1. SCOPE

1.1.

This Regulation applies to head-restraint devices conforming to one of the types defined in paragraph 2.2 below (1).

1.1.1.

It does not apply to head-restraint devices which may be fitted to folding seats or seats facing towards the side or towards the rear.

1.1.2.

It applies to seat backs themselves, when they are so designed as to serve also as head restraints as defined in paragraph 2.2 below.

2. DEFINITIONS

For the purposes of this Regulation,

2.1.

‘Vehicle type’ means a category of power-driven vehicles which do not differ in such essential respects as:

2.1.1.

the lines and internal dimensions of the bodywork constituting the passenger compartment,

2.1.2.

the types and dimensions of the seats,

2.1.3.

type and dimensions of head-restraint attachment and of the relevant parts of the vehicle structure in the case of head restraint directly anchored to the vehicle structure;

2.2.

‘Head restraint’ means a device whose function is to limit the rearward displacement of an adult occupant’s head in relation to his torso in order to reduce the danger of injury to the cervical vertebrae of that occupant in the event of an accident;

2.2.1.

‘Integrated head restraint’ means a head restraint constituted by the upper part of the seat back. Head restraints corresponding to the definitions in paragraphs 2.2.2 and 2.2.3 below, but which cannot be detached from the seat or the vehicle structure except by the use of tools or following the partial or total removal of the seat furnishings, correspond to this definition;

2.2.2.

‘Removable head restraint’ means a head restraint constituted by a component separable from the seat, designed for insertion and positive retention in the seat back structure;

2.2.3.

‘Separate head restraint’ means a head restraint constituted by a separate component of the seat, designed for insertion and/or positive retention in the structure of the vehicle;

2.3.	‘Type of seat’ means a category of seats which do not differ in their dimensions, in their framework or in their padding, although they may differ in finish and colour;

2.4.	‘Type of head restraint’ means a category of head restraints which do not differ in their dimensions, in their framework or in their padding, although they may differ in finish, in colour and in covering;

2.5.	‘Reference point’ of the seat (‘H point’) (see Annex 3 to this Regulation) means the trace, in a vertical plane longitudinal in relation to the seat, of the theoretical axis of rotation between the leg and the torso of a human body represented by a manikin;

2.6.

‘Reference line’ means a straight line which, either on a test manikin having the weight and dimensions of a fiftieth percentile adult male or on a test manikin having identical characteristics, passes through the joint of the leg with the pelvis and the joint of the neck with the thorax. On the manikin reproduced in Annex 3 to this Regulation, for determining the H point of the seat, the reference line is that shown in figure 1 in the appendix to that Annex;

2.7.	‘Head line’ means a straight line passing through the centre of gravity of the head and through the joint of the neck with the thorax. When the head is at rest the head line is situated in the extension of the reference line;

2.8.	‘Folding seat’ means an auxiliary seat intended for occasional use and normally folded;

2.9.

‘Adjustment system’ means the device by which the seat or its parts can be adjusted to a position suited to the morphology of the seated occupant.

This device may, in particular, permit:

2.9.1.

longitudinal displacement,

2.9.2.

vertical displacement,

2.9.3.

angular displacement;

2.10.

‘Displacement system’ means a device by which the seat or one of its parts can be displaced or rotated, without a fixed intermediate position, to permit easy access to the space behind the seat concerned.

6. GENERAL SPECIFICATIONS

6.1.

The presence of the head restraint shall not be an additional cause of danger to occupants of the vehicle. In particular it shall not in any position of use exhibit any dangerous roughness or sharp edge liable to increase the risk or seriousness of injury to the occupants. Parts of the head restraint which are situated in the impact zone defined below shall be capable of dissipating energy in the manner specified in Annex 6 to this Regulation.

6.1.1.

The impact zone is bounded laterally by two vertical longitudinal planes, one on each side of and each 70 mm distant from the plane of symmetry of the seat considered.

6.1.2.

The impact zone is limited in height to the part of the head restraint situated above the plane perpendicular to the reference line R and 635 mm distant from the H point.

6.1.3.

By derogation from the above provisions, the requirements concerning energy absorption shall not apply to the rear faces of head restraints for seats behind which there are no other seats.

6.2.

Parts of the front and rear faces of the head restraint, excluding parts of the rear faces of head restraints designed to be installed in seats behind which no other seating positions are provided, which are situated outward of the longitudinal vertical planes defined above shall be so padded as to prevent any direct contact of the head with the components of the structure, which shall, in those areas which can be contacted by a sphere of 165 mm diameter, have a radius of curvature of not less than 5 mm.

Alternatively, these components may be considered satisfactory if they pass the energy-absorption test described in Annex 6 to this Regulation. If the above-mentioned parts of the head restraints and their supports are covered with material softer than 50 Shore (A) hardness, the requirements of this paragraph, with the exception of those relating to energy absorption as defined in Annex 6 to this Regulation, shall apply only to the rigid parts.

6.3.

The head restraint shall be anchored to the seat or, where appropriate, to the vehicle structure, in such a way that no rigid and dangerous part projects from the padding of the head restraint, from the anchorage or from the seat back as a result of the pressure exerted by the head during the test.

6.4.

The height of the head restraint, measured in accordance with the requirements of paragraph 7.2 below, shall conform to the following specifications:

6.4.1.

The height of head restraints shall be measured as described in paragraph 7.2 below.

6.4.2.

For head restraints not adjustable for height, the height shall be not less than 800 mm in the case of front seats and 750 mm in the case of other seats.

6.4.3.

For head restraints adjustable for height:

6.4.3.1.

the height shall be not less than 800 mm in the case of front seats and 750 mm in the case of other seats; this value shall be obtained in a position between the highest and lowest positions to which adjustment is possible;

6.4.3.2.

there shall be no ‘use position’ resulting in a height of less than 750 mm;

6.4.3.3.

in the case of seats other than the front seats the head restraints may be such that they can be displaced to a position resulting in a height of less than 750 mm, provided that such position is clearly recognisable to the occupant as not being included for the use of the head restraint;

6.4.3.4.

in the case of front seats head restraints may be such that they can be automatically displaced when the seat is not occupied, to a position resulting in a height of less than 750 mm, provided that they automatically return to the position of use when the seat is occupied.

6.4.4.

The dimensions mentioned in paragraphs 6.4.2 and 6.4.3.1 above may be less than 800 mm in the case of front seats and 750 mm in the case of other seats to leave adequate clearance between the head restraint and the interior surface of the roof, the windows or any part of the vehicle structure; however, the clearance shall not exceed 25 mm. In the case of seats fitted with displacement and/or adjustment systems, this shall apply to all seat positions. Furthermore, by derogation to paragraph 6.4.3.2 above, there shall not be any ‘use position’ resulting in a height lower than 700 mm.

6.4.5.

By derogation to the height requirements mentioned in paragraphs 6.4.2 and 6.4.3.1 above, the height of any head restraint designed to be provided in rear centre seats or seating positions shall be not less than 700 mm.

6.5.

The height of the device on which the head rests, measured as prescribed in paragraph 7.2, shall in the case of a head restraint adjustable for height be not less than 100 mm.

6.6.

There shall be no gap of more than 60 mm between the seat back and the head restraint in the case of a device not adjustable for height.

6.6.1.

If the head restraint is adjustable for height it shall, in its lowest position, be not more than 25 mm from the top of the seat back.

6.6.2.

In the case of a head restraint not adjustable for height, the area to be considered is:

6.6.2.1.

above a plane perpendicular to the reference line at 540 mm from the R point and

6.6.2.2.

between two vertical longitudinal planes passing at 85 mm on either side of the reference line.

In this area, one or more gaps, which regardless of its shape can show a distance ‘a’ measured as described in paragraph 7.5 of more than 60 mm, are permitted provided that after the additional test under paragraph 7.4.3.4, the requirements of paragraph 7.4.3.6 are still met.

6.6.3.

In the case of head restraints adjustable for height, one or more gaps, which regardless of its shape can show a distance ‘a’ measured as described in paragraph 7.5 of more than 60 mm, are permitted on the part of the device serving as the head restraint provided that, after the additional test under paragraph 7.4.3.4, the requirements of paragraph 7.4.3.6 are still met.

6.7.

The width of the head restraint shall be such as to provide suitable support for the head of a person normally seated. In the plane of measurement of width defined in paragraph 7.3 below, the head restraint shall cover an area extending not less than 85 mm to each side of the plane of symmetry of the seat for which the head restraint is intended, that distance being measured as prescribed in paragraph 7.3.

6.8.

The head restraint and its anchorage shall be such that the maximum backward displacement of the head permitted by the head restraint and measured in conformity with the static procedure prescribed in paragraph 7.4 below is less than 102 mm.

6.9.

The head restraint and its anchorage shall be strong enough to bear without failure the load prescribed in paragraph 7.4.3.7 below.

6.10.

If the head restraint is adjustable, it must not be possible to exceed the maximum prescribed height for use without voluntary action by the user in addition to adjusting operation.

7. TESTS

7.1. Determination of the reference point (H point) of the seat in which the head restraint is incorporated

This point shall be determined in conformity with the requirements of Annex 3 to this Regulation.

7.2. Determination of the height of the head restraint

7.2.1. All lines shall be drawn in the plane of symmetry of the seat considered, the intersection of which plane with the seat determines the contour of the head restraint and of the seat back (see Annex 4, figure 1, to this Regulation).

7.2.2. The manikin corresponding to a fiftieth percentile adult male or the manikin shown in Annex 3 to this Regulation shall be placed in a normal position on the seat. The seat back, if inclinable, shall be locked in a position corresponding to a rearward inclination of the reference line of the manikin’s torso of as nearly as possible 25o from the vertical.

7.2.3. The projection of the reference line of the manikin shown in Annex 3 shall in the case of the seat considered be drawn in the plane specified in paragraph 7.2.1. The tangent S to the top of the head restraint shall be drawn perpendicular to the reference line.

7.2.4. The distance h from the H point to the tangent S is the height to be taken into consideration in implementing the requirement of paragraph 6.4.

7.3. Determination of the width of the head restraint (see Annex 4, figure 2, to this Regulation).

7.3.1. The plane S1 perpendicular to the reference line and situated 65 mm below the tangent S defined in paragraph 7.2.3 defines a section in the head restraint bounded by the outline C. The direction of the straight lines tangential to C representing the intersection of the vertical planes (P and P’), parallel to the plane of symmetry of the seat considered, with the plane S1 shall be traced in the plane S1.

7.3.2. The width of the head restraint to be taken into consideration in implementing the requirement of paragraph 6.7 is the distance L separating the traces of planes P and P’ in plane S1.

7.3.3. The width of the head restraint shall if necessary also be determined 635 mm above the reference point of the seat, this distance being measured along the reference line.

7.4. Determination of the effectiveness of the device

7.4.1. The effectiveness of the head restraint shall be checked by the static test described below.

7.4.2. Preparation for the test

7.4.2.1.

If the head restraint is adjustable it shall be set in the highest position.

7.4.2.2.

In the case of a bench seat, where part or all of the supporting frame (including that of the head restraints) is common to more than one seating position, the test shall be conducted simultaneously for all those seating positions.

7.4.2.3.

If the seat or the seat-back is adjustable relative to a head restraint anchored to the vehicle structure, it shall be placed in the most unfavourable position as considered by the technical service.

7.4.3. Testing

7.4.3.1.

All lines shall be drawn in the vertical plane of symmetry of the seat considered (see Annex 5 to this Regulation).

7.4.3.2.

A projection of the reference line R shall be drawn in the plane referred to in paragraph 7.4.3.1.

7.4.3.3.

The displaced reference line R1 shall be determined by applying to the part simulating the back in the manikin referred to in Annex 3 to this Regulation an initial force producing a rearward moment of 37,3 daNm about the H point.

7.4.3.4.

By means of a spherical head 165 mm in diameter an initial force producing a moment of 37,3 daNm about the H point shall be applied at right angles to the displaced reference line R1 at a distance of 65 mm below the top of the head restraint the reference line being retained in its displaced position R1 as determined in accordance with the requirements of paragraph 7.4.3.3 above.

7.4.3.4.1.

If the presence of gaps prevents the application of the force prescribed above at 65 mm from the top of the head restraint, the distance may be reduced so that the axis of the force passes through the centre line of the frame element nearest to the gap.

7.4.3.4.2.

In the case described in paragraphs 6.6.2 and 6.6.3 above, the test shall be repeated by applying to each gap, using a sphere of 165 mm in diameter, a force:

passing through the centre of gravity of the smallest of the sections of the gap, along transversal planes parallel to the reference line, and reproducing a moment of 37,3 daNm about the ‘R’ point.

7.4.3.5.

The tangent Y to the spherical head, parallel to the displaced reference line R1, shall be determined.

7.4.3.6.

The distance X between the tangent Y and the displaced reference line R1 shall be measured. The requirement of paragraph 6.8 shall be considered to be met if the distance X is less than 102 mm.

7.4.3.7.

In cases where the force prescribed in paragraph 7.4.3.4 is applied at a distance of 65 mm or less below the top of the head restraint, and only in such cases, it shall be increased to 89 daN unless breakage of the seat or its back occurs earlier.

7.5. Determination of distance ‘a’ of head restraint gaps (see Annex 7 to this Regulation)

7.5.1. The distance ‘a’ shall be determined for each gap and in relation to the front face of the head restraint, by means of a sphere having a diameter of 165 mm;

7.5.2. The sphere shall be put into contact with the gap in a point of the gap area which allows the maximum sphere intrusion considering no load to be applied;

7.5.3. The distance between the two points of contact of the sphere with the gap will constitute the distance ‘a’ to be considered for the evaluation of the provisions under paragraph 6.6.2 and 6.6.3.

8. CONFORMITY OF PRODUCTION

8.1.

Every head restraint or seat bearing an approval mark in conformity with Annex 2 shall conform to the type of head restraint approved and comply with the conditions prescribed in paragraphs 6 and 7 above.

8.2.

In order to verify conformity as aforesaid, a sufficient number of random checks shall be performed on serially-produced head restraints.

8.3.

Head restraints offered or to be offered for sale shall be used for the tests.

8.4.

Head restraints selected for verification of conformity with an approved type shall undergo the test described in paragraph 7 of this Regulation.

9. PENALTIES FOR NON-CONFORMITY OF PRODUCTION

9.1. Approved head restraints

The approval granted in respect of a type of head restraint pursuant to this Regulation may be withdrawn if head restraints bearing the particulars referred to in paragraph 5.4 above fail to pass the random checks or do not conform to the type approved.

9.2. If a Contracting Party to the Agreement applying this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a communication form conforming to the model in Annex 1 to this Regulation.

10. MODIFICATION AND EXTENSION OF APPROVAL OF A TYPE OF HEAD RESTRAINT

10.1.

Every modification of the type of head restraint shall be notified to the administrative department which approved the type of head restraint. The department may then either:

10.1.1.

Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the head restraint still complies with the requirements; or

10.1.2.

Require a further test report from the technical service responsible for conducting the tests.

10.2.

Confirmation or refusal of approval, specifying the alterations shall be communicated by the procedure specified in paragraph 5.3 above to the Parties to the Agreement applying this Regulation.

10.3.

ANNEX 3

Procedure for determining the ‘H’ point and the actual torso angle for seating positions in motor vehicles

1. PURPOSE

The procedure described in this Annex is used to establish the ‘H’ point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer (1).

2. DEFINITIONS

For the purposes of this Annex:

2.1.

‘Reference data’ means one or several of the following characteristics of a seating position:

2.1.1.

the ‘H’ point and the ‘R’ point and their relationship;

2.1.2.

the actual torso angle and the design torso angle and their relationship.

2.2.	‘Three-dimensional “H” point machine’ (3-D H machine) means the device used for the determination of ‘H’ points and actual torso angles. This device is described in Appendix 1 to this Annex.

2.3.

‘H’ point means the pivot centre of the torso and thigh of the 3-D H machine installed in the vehicle seat in accordance with paragraph 4 below. The ‘H’ point is located in the centre of the centreline of the device which is between the ‘H’ point sight buttons on either side of the 3-D H machine. The ‘H’ point corresponds theoretically to the ‘R’ point (for tolerances see paragraph 3.2.2 below). Once determined in accordance with the procedure described in paragraph 4, the ‘H’ point is considered fixed in relation to the seat-cushion structure and to move with it when the seat is adjusted.

2.4.	‘R’ point or ‘seating reference point’ means a design point defined by a vehicle manufacturer for each seating position and established with respect to the three-dimensional reference system.

2.5.	‘Torso-line’ means the centreline of the probe of the 3-D H machine with the probe in the fully rearward position.

2.6.	‘Actual torso angle’ means the angle measured between a vertical line through the ‘H’ point and the torso line using the back angle quadrant on the 3-D H machine. The actual torso angle corresponds theoretically to the design torso angle (for tolerances see paragraph 3.2.2 below).

2.7.	‘Design torso angle’ means the angle measures between a vertical line through the ‘R’ point and the torso line in a position which corresponds to the design position of the seat-back established by the vehicle manufacturer.

2.8.

‘Centreplane of occupant’ (C/LO) means the median plane of the 3-D H machine positioned in each designated seating position; it is represented by the coordinate of the ‘H’ point on the ‘Y’ axis. For individual seats, the centreplane of the seat coincides with the centreplane of the occupant. For other seats, the centreplane of the occupant is specified by the manufacturer;

2.9.	‘Three-dimensional reference system’ means a system as described in Appendix 2 to this Annex;

2.10.

2.11.

‘Vehicle measuring attitude’ means the position of the vehicle as defined by the coordinates of fiducial marks in the three-dimensional reference system.

3. REQUIREMENTS

3.1. Data presentation

For each seating position where reference data are required in order to demonstrate compliance with the provisions of the present Regulation, all or an appropriate selection of the following data shall be presented in the form indicated in appendix 3 to this Annex:

3.1.1.

the coordinates of the ‘R’ point relative to the three-dimensional reference system;

3.1.2.

the design torso angle;

3.1.3.

all indications necessary to adjust the seat (if it is adjustable) to the measuring position set out in paragraph 4.3 below.

3.2. Relationship between measured data and design specifications

3.2.1.

The coordinates of the ‘H’ point and the value of the actual torso angle obtained by the procedure set out in paragraph 4 below shall be compared, respectively, with the coordinates of the ‘R’ point and the value of the design torso angle indicated by the vehicle manufacturer.

3.2.2.

The relative positions of the ‘R’ point and the ‘H’ point and the relationship between the design torso angle and the actual torso angle shall be considered satisfactory for the seating position in question if the ‘H’ point, as defined by its coordinates, lies within a square of 50 mm side length with horizontal and vertical sides whose diagonals intersect at the ‘R’ point, and if the actual torso angle is within 5 degree of the design of the torso angle.

3.2.3.

If these conditions are met, the ‘R’ point and the design torso angle, shall be used to demonstrate compliance with the provisions of this Regulation.

3.2.4.

If the ‘H’ point or the actual torso angle does not satisfy the requirements of paragraph 3.2.2 above, the ‘H’ point and the actual torso angle shall be determined twice more (three times in all). If the results of two of these three operations satisfy the requirements, the conditions of paragraph 3.2.3 above shall apply.

3.2.5.

If the results of at least two of the three operations described in paragraph 3.2.4 above do not satisfy the requirements of paragraph 3.2.2 above, or if the verification cannot take place because the vehicle manufacturer has failed to supply information regarding the position of the ‘R’ point or regarding the design torso angle, the centroid of the three measured points or the average of the three measured angles shall be used and be regarded as applicable in all cases where the ‘R’ point or the design torso angle is referred to in this Regulation.

4. PROCEDURE FOR ‘H’ POINT AND ACTUAL TORSO ANGLE DETERMINATION

4.1. The vehicle shall be preconditioned at the manufacturer’s discretion, at a temperature of 20 ± 10 degrees C to ensure that the seat material reaches the room temperature. If the seat to be checked has never been sat upon, a 70 to 80 kg person or device shall sit on the seat twice for one minute to flex the cushion and back. At the manufacturer’s request, all seat assemblies shall remain unloaded for a minimum period of 30 min prior to installation of the 3-D H machine.

4.2. The vehicle shall be at the measuring attitude defined in paragraph 2.11 above.

4.3. The seat, if it is adjustable, shall be adjusted first to the rearmost normal driving or riding position, as indicated by the vehicle manufacturer, taking into consideration only the longitudinal adjustment of the seat, excluding seat travel used for purposes other than normal driving or riding positions. Where other modes of seat adjustment exist (vertical, angular, seat-back. etc.) these will be then adjusted to the position specified by the vehicle manufacturer. For suspension seats, the vertical position shall be rigidly fixed corresponding to a normal driving position as specified by the manufacturer.

4.4. The area of the seating position contacted by the 3-D H machine shall be covered by a muslin cotton, of sufficient size and appropriate texture, described as a plain cotton fabric having 18,9 threads per cm2 and weighing 0,228 kg/m2 or knitted or non-woven fabric having equivalent characteristics.

If test is run on a seat outside the vehicle, the floor on which the seat is placed shall have the same essential characteristics (2) as the floor of the vehicle in which the seat is intended to be used.

4.5. Place the seat and back assembly of the 3-D H machine so that the centreplane of the occupant (C LO) coincides with the centreplane of the 3-D H machine. At the manufacturer’s request, the 3-D H machine may be moved inboard with respect to the C LO if the 3-D H machine is located so far outboard that the seat edge will not permit levelling of the 3-D H machine.

4.6. Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by using the T-bar and lower leg assembly. A line through the ‘H’ point sight buttons shall be parallel to the ground and perpendicular to the longitudinal centreplane of the seat.

4.7. Adjust the feet and leg positions of the 3-D H machine as follows:

4.7.1. Designated seating position: driver and outside front passenger

4.7.1.1.

Both feet and leg assemblies shall be moved forward in such a way that the feet take up natural positions on the floor, between the operating pedals if necessary. Where possible the left foot shall be located approximately the same distance to the left of the centreplane of the 3-D H machine as the right foot is to the right. The spirit level verifying the transverse orientation of the 3-D H machine is brought to the horizontal by readjustment of the seat pan if necessary, or by adjusting the leg and foot assemblies towards the rear. The line passing through the ‘H’ point sight buttons shall be maintained perpendicular to the longitudinal centreplane of the seat.

4.7.1.2.

If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by the structure, move the left foot until it is supported. The alignment of the sight buttons shall be maintained.

4.7.2. Designated seating position: outboard rear

For rear seats or auxiliary seats, the legs are located as specified by the manufacturer. If the feet then rest on parts of the floor which are at different levels, the foot which first comes into contact with the front seat shall serve as a reference and the other foot shall be so arranged that the spirit level giving the transverse orientation of the seat of the device indicates the horizontal.

4.7.3. Other designated seating positions:

The general procedure indicated in paragraph 4.7.1 above shall be followed except that the feet shall be placed as specified by the vehicle manufacturer.

4.8. Apply lower leg and thigh weights and level the 3-D H machine.

4.9. Tilt the back pan forward against the forward stop and draw the 3-D H machine away from the seat-back using the T-bar. Reposition the 3-D H machine on the seat by one of the following methods:

4.9.1.

If the 3-D H machine tends to slide rearward, use the following procedure. Allow the 3-D H machine to slide rearward until a forward horizontal restraining load on the T-bar is no longer required, i.e. until the seat pan contacts the seat-back. If necessary, reposition the lower leg;

4.9.2.

If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the 3-D H machine rearwards by applying a horizontal rearward load to the T-bar until the seat pan contacts the seat-back (see figure 2 of Appendix 1 to this Annex).

4.10. Apply a 100 + 10 N load to the back and pan assembly of the 3-D H machine at the intersection of the hip angle quadrant and the T-bar housing. The direction of load application shall be maintained along a line passing by the above intersection to a point just above the thigh bar housing (see figure 2 of Appendix 1 to this Annex). Then carefully return the back pan to the seat-back. Care must be exercised throughout the remainder of the procedure to prevent the 3-D H machine from sliding forward.

4.11. Install the right and left buttock weights and then, alternately, the eight torso weights. Maintain the 3-D H machine level.

4.12. Tilt the back pan forward to release the tension on the seatback. Rock the 3-D H machine from side to side through 10° arc (5° to each side of the vertical centreplane) for three complete cycles to release any accumulated friction between the 3-D H machine and the seat.

During the rocking action, the T-bar of the 3-D H machine may tend to diverge from the specified horizontal and vertical alignment. The T-bar must therefore be restrained by applying an appropriate lateral load during the rocking motions. Care shall be exercised in holding the T-bar and rocking the 3-D H machine to ensure that no inadvertent exterior loads are applied in a vertical or fore and aft direction.

The feet of the 3-D H machine are not to be restrained or held during this step. If the feet change position, they should be allowed to remain in that attitude for the moment.

Carefully return the back pan to the seat-back and check the two spirit levels for zero position. If any movement of the feet has occurred during the rocking operation of the 3-D H machine, they must be repositioned as follows:

Alternately, lift each foot off the floor the minimum necessary amount until no additional foot movement is obtained. During this lifting, the feet are to be free to rotate; and no forward or lateral loads are to be applied. When each foot is placed back in the down position, the heel is to be in contact with the structure designed for this;

Check the lateral spirit level for zero position; if necessary, apply a lateral load to the top of the back pan sufficient to level the 3-D H machine’s seat pan on the seat.

4.13. Holding the T-bar to prevent the 3-D H machine from sliding forward on the seat cushion, proceed as follows:

(a)	return the back pan to the seat back;

(b)

alternately apply and release a horizontal rearward load, not to exceed 25 N, to the back angle bar at a height approximately at the centre of the torso weights until the hip angle quadrant indicates that a stable position has been reached after load release. Care shall be exercised to ensure that no exterior downward or lateral loads are applied to the 3-D H machine. If another level adjustment of the 3-D H machine is necessary, rotate the back pan forward, re-level, and repeat the procedure from 4.12.

4.14. Take all measurements:

4.14.1.

The coordinates of the ‘H’ point are measured with respect to the three-dimensional reference system;

4.14.2.

The actual torso angle is read at the back angle quadrant of the 3-D H machine with the probe in its fully rearward position.

4.15. If a re-run of the installation of the 3-D H machine is desired, the seat assembly should remain unloaded for a minimum period of 30 min prior to the re-run. The 3-D H machine should not be left loaded on the seat assembly longer than the time required to perform the test.

4.16. If the seats in the same row can be regarded as similar (bench seat, identical seats, etc.) only one ‘H’ point and one ‘actual torso angle’ shall be determined for each row of seats, the 3-D H machine described in Appendix 1 to this Annex being seated in a place regarded as representative for the row. This place shall be:

4.16.1.

in the case of the front row, the driver’s seat;

4.16.2.

in the case of the rear row or rows, an outer seat.

(1) In any seating position other than front seats where the ‘H’ point cannot be determined using the ‘Three-dimensional “H” point machine’or procedures, the ‘R’ point indicated by the manufacturer may be taken as a reference at the discretion of the competent authority.

(2) Tilt angle, height difference with a seat mounting, surface texture, etc.

Appendix 1

Description of the three dimensional ‘H’ point machine (*1)

(3-D H machine)

1. Back and seat pans

The back and seat pans are constructed of reinforced plastic and metal; they simulate the human torso and thigh and are mechanically hinged at the ‘H’ point. A quadrant is fastened to the probe hinged at the ‘H’ point to measure the actual torso angle. An adjustable thigh bar, attached to the seat pan, establishes the thigh centreline and serves as a baseline for the hip angle quadrant.

2. Body and leg elements

Lower leg segments are connected to the seat pan assembly at the T-bar joining the knees, which is a lateral extension of the adjustable thigh bar. Quadrants are incorporated in the lower leg segments to measure knee angles. Shoe and foot assemblies are calibrated to measure the foot angle. Two spirit levels orient the device in space. Body element weights are placed at the corresponding centres of gravity to provide seat penetration equivalent to a 76 kg male. All joints of the 3-D H machine should be checked for free movement without encountering noticeable friction.

The machine corresponds to that described in ISO Standard 6549-1980.

Appendix 2

THREE-DIMENSIONAL REFERENCE SYSTEM

The three-dimensional reference system is defined by three orthogonal planes established by the vehicle manufacturer (see figure) (*1).

The vehicle measuring attitude is established by positioning the vehicle on the supporting surface such that the coordinates of the fiducial marks correspond to the values indicated by the manufacturer.

The coordinates of the ‘R’ point and the ‘H’ point are established in relation to the fiducial marks defined by the vehicle manufacturer.

ANNEX 6

TEST PROCEDURE FOR CHECKING ENERGY DISSIPATION

1. Installation, test apparatus, recording instruments and procedure

1.1. Installation

The head restraint covered with an energy dissipating material shall be fitted and tested on the seat or the structural part of the vehicle in which it is installed. The structural component shall be firmly secured to the test bench so as to remain stationary when the impact is applied, and the base on which it rests shall, in the absence of a particular specification for which reasons are given, be approximately horizontal. The seat back, if it can be adjusted, shall be bolted into the position described in paragraph 7.2.2 of this Regulation.

The head restraint shall be mounted on the seat back, as it is presented in the vehicle. In the case of a separate head restraint, it shall be secured to the part of the vehicle structure to which it is normally secured.

If the head restraint is adjustable it shall be placed in the most unfavourable position the adjustment device permits.

1.2. Test apparatus

1.2.1.

This apparatus consists of a pendulum whose pivot is supported by ball-bearings and whose reduced mass (*1) at its centre of percussion is 6,8 kg. The lower extremity of the pendulum consists of a rigid headform 165 mm in diameter whose centre is identical with the centre of percussion of the pendulum.

1.2.2.

The headform shall be fitted with two accelerometers and a speed-measuring device, all capable of measuring values in the direction of impact.

1.3. Recording instruments

The recording instruments used shall be such that measurements can be made with the following degrees of accuracy:

1.3.1.

Acceleration:

accuracy = ± 5 % of the actual value

frequency class of the measurement chain: CFC 600 corresponding to the characteristics of ISO standard 6487 (1987)

Transverse sensitivity ≤ 5 % of the lowest point on the scale.

1.3.2.

Speed:

accuracy = ± 2,5 % of the real value;

sensitivity = 0,5 km/h

1.3.3.

Time recording

the instrumentation shall enable the action to be recorded throughout its duration and readings to be made within one one-thousandth of a second:

the beginning of the impact at the moment of first contact between the headform and the item being tested shall be detected on the recordings used for analysing the test.

1.4. Test procedure

1.4.1.

With the head restraint installed and adjusted as indicated in paragraph 1.1 of this Annex, the impact shall take place at points selected by the laboratory in the impact zone defined in paragraph 6.1 of this Regulation and possibly outside the impact zone defined in paragraph 6.2 of this Regulation on surfaces with a radius of curvature of less than 5 mm.

1.4.1.1.

On the rear surface, the direction of impact from the rear towards the front in a longitudinal plane shall be at an angle of 45o to the vertical.

1.4.1.2.

On the front surface, the direction of impact from the front towards the rear, in a longitudinal plane, shall be horizontal.

1.4.1.3.

The front and rear zones are bounded by the horizontal plane tangential to the top of the head restraint as determined in paragraph 7.2 of this Regulation.

1.4.2.

The headform shall strike the test item at a speed of 24,1 km/h; this speed shall be achieved either by the mere energy of propulsion or by using an additional impelling device.

2. Results

In tests carried out by the above procedure the deceleration of the headform shall not exceed 80 g continuously for more than 3 milliseconds. The deceleration rate shall be taken as the average of the readings on the two decelerometers.

3. Equivalent procedures

3.1.

Equivalent test procedures shall be permitted on condition that the results required in paragraph 2 above can be obtained, in particular, items of test apparatus may be oriented differently so long as the relative angles between the head restraint and the direction of impact are respected.

3.2.

Responsibility for demonstrating the equivalence of a method other than that described in paragraph 1 shall rest with the person using that other method.

(*1) The relationship of the reduced mass ‘mr ’ of the pendulum to the total mass ‘m’ of the pendulum at a distance ‘a’ between the centre of percussion and the axis of rotation and at a distance ‘l’ between the centre of gravity and the axis of rotation is given by the formula: mr = m (l/a).

1. SCOPE AND PURPOSE

1.1.

This Regulation applies to external projections of category M1 vehicles (1). It does not apply to exterior rear-view mirrors or to the ball of towing devices.

1.2.

The purpose of this Regulation is to reduce the risk or seriousness of bodily injury to a person hit by the bodywork or brushing against it in the event of a collision. This is valid both when the vehicle is stationary and in motion.

2. DEFINITIONS

For the purposes of this Regulation:

2.1.	‘Approval of a vehicle’ means the approval of a vehicle type with regard to its external projections.

2.2.	‘Vehicle type’ means a category of motor vehicles which do not differ in such essential respects as, shape or materials of the external surface.

2.3.	‘External surface’ means the outside of the vehicle including the bonnet, the lid of the luggage compartment, the doors, the wings, the roof, the lighting and light-signalling devices and the visible strengthening components.

2.4.

‘Floor line’ means the line determined as follows:

Successively position round a laden vehicle a cone with a vertical axis the height of which is not defined, and with a half angle of 30° in such a way that it contacts, constantly and as low as possible, the external surface of the vehicle. The floor line is the geometric trace of these points of contact. In determining the floor line, the jacking points, exhaust pipes or wheels shall not be taken into consideration. The gaps of the wheel arches are assumed to be filled in by an imaginary surface forming a smooth continuation of the surrounding external surface. At both ends of the vehicle the bumper shall be taken into consideration when establishing the floor line. Dependent upon the particular vehicle the floor line trace may occur at the bumper section extremity or at the body panel below the bumper. Where two or more points of contact occur simultaneously, the lower point of contact shall be used to determine the floor line.

2.5.	‘Radius of curvature’ means the radius of the arc of a circle which comes closest to the rounded form of the component under consideration.

2.6.

‘Laden vehicle’ means the vehicle laden to the maximum permitted technical mass. Vehicles equipped with hydropneumatic, hydraulic or pneumatic suspension or a device for automatic levelling according to load shall be tested with the vehicle in the most adverse normal running condition specified by the manufacturer.

2.7.

‘Extreme outer edge’ of the vehicle means, in relation to the sides of the vehicle, the plane parallel to the median longitudinal plane of the vehicle coinciding with its outer lateral edge, and, in relation to the front and rear ends, the perpendicular transverse plane of the vehicle coinciding with its outer front and rear edges, account not being taken of the projection:

2.7.1.

of tyres near their point of contact with the ground, and connections for tyre pressure gauges;

2.7.2.

of any anti-skid devices which may be mounted on the wheels;

The hardness measurement shall be taken with the component as installed on the vehicle. Where it is impossible to carry out a hardness measurement by the Shore A procedure, comparable measurements shall be used for evaluation.

5.6.

The provisions of the above paragraphs 5.1 to 5.5 shall apply in addition to the particular specifications of the following paragraph 6, except where these particular specifications expressly provide otherwise.

6. PARTICULAR SPECIFICATIONS

6.1. Ornaments.

6.1.1.

Added ornaments which project more than 10 mm from their support shall retract, become detached or bend over under a force of 10 daN exerted at their most salient point in any direction in a plane approximately parallel to the surface on which they are mounted. These provisions shall not apply to ornaments on radiator grilles, to which only the general requirements of paragraph 5 shall apply. To apply the 10 daN force a flat-ended ram of not more than 50 mm diameter shall be used. Where this is not possible, an equivalent method shall be used. After the ornaments are retracted, detached or bent over, the remaining projections shall not project more than 10 mm. These projections shall in any case satisfy the provisions of paragraph 5.2. If the ornament is mounted on a base, this base is regarded as belonging to the ornament and not to the supporting surface.

6.1.2.

Protective strips or shielding on the external surface shall not be subject to the requirements of paragraph 6.1.1 above; however, they shall be firmly secured to the vehicle.

6.2. Headlights.

6.2.1.

Projecting visors and rims shall be permitted on headlights, provided that their projection, as measured in relation to the external transparent surface of the headlight does not exceed 30 mm and their radius of curvature is at least 2,5 mm throughout. In the case of a headlamp mounted behind an additional transparent surface, the projection shall be measured from the outermost transparent surface. The projections shall be determined according to the method described in paragraph 3 of Annex 3 to this Regulation.

6.2.2.

Retracting headlights shall meet the provisions of paragraph 6.2.1 above in both the operative and retracted positions.

6.2.3.

The provisions of paragraph 6.2.1 above do not apply to headlamps which are sunk into the bodywork or which are ‘overhung’ by the bodywork, if the latter complies with the requirements of paragraph 6.9.1.

6.3. Grilles and gaps.

6.3.1.

The requirements of paragraph 5.4 shall not apply to gaps between fixed or movable elements, including those forming part of air intake or outlet grilles and radiator grilles, provided that the distance between consecutive elements does not exceed 40 mm and provided that the grilles and gaps have a functional purpose. For gaps of between 40 mm and 25 mm the radii of curvature shall be 1 mm or more. However, if the distance between two consecutive elements is equal to or less than 25 mm, the radii of curvature of external faces of the elements shall not be less than 0,5 mm. The distance between two consecutive elements of grilles and gaps shall be determined according to the method described in paragraph 4 of Annex 3 to this Regulation.

6.3.2.

The junction of the front with the side faces of each element forming a grille or gap shall be blunted.

6.4. Windscreen wipers.

6.4.1.

The windscreen wiper fittings shall be such that the wiper shaft is furnished with a protective casing which has a radius of curvature meeting the requirements of paragraph 5.4 above and an end surface area of not less than 150 mm2. In the case of rounded covers, these shall have a minimum projected area of 150 mm2 when measured not more than 6,5 mm from the point projecting furthest. These requirements shall also be met by rear window wipers and headlamp wipers.

6.4.2.

Paragraph 5.4 shall not apply to the wiper blades or to any supporting members. However, these units shall be so made as to have no sharp angles or pointed or cutting parts.

6.5. Bumpers.

6.5.1.

The ends of the bumpers shall be turned in towards the external surface in order to minimise the risk of fouling. This requirement is considered to be satisfied if either the bumper is recessed or integrated within the bodywork or the end of the bumper is turned in so that it is not contactable by a 100 mm sphere and the gap between the bumper end and the surrounding bodywork does not exceed 20 mm.

6.5.2.

If the line of the bumper which corresponds to the outline contour of the car vertical projection is on a rigid surface, that surface shall have a minimum radius of curvature of 5 mm at all its points lying from the contour line to 20 mm inward, and a minimum radius of curvature of 2,5 mm in all other cases. This provision applies to that part of the zone lying from the contour line to 20 mm inward which is situated between and in front (or rear in case of the rear bumper) of tangential points with the contour line of two vertical planes each forming with the longitudinal plane of symmetry of the vehicle an angle of 15° (see fig. 1).

6.5.3.

The requirement of paragraph 6.5.2 shall not apply to parts on or of the bumper or to bumper insets which have a projection of less than 5 mm, with special reference to joint covers and jets for headlamp washers; but the outward facing angles of such parts shall be blunted, save where such parts protrude less than 1,5 mm.

6.6. Handles, hinges and push-buttons of doors, luggage compartments and bonnets; fuel tank filler caps and covers

6.6.1.

The projection shall not exceed 40 mm in the case of door or luggage compartment handles and 30 mm in all other cases.

Figure 1

6.6.2.

If lateral door handles rotate to operate, they shall meet one or other of the following requirements:

6.6.2.1.

In the case of handles which rotate parallel to the plane of the door, the open end of handles must be directed towards the rear. The end of such handles shall be turned back towards the plane of the door and fitted into a protective surround or be recessed.

6.6.2.2.

Handles which pivot outwards in any direction which is not parallel to the plane of the door shall, when in the closed position, be enclosed in a protective surround or be recessed. The open end shall face either rearwards or downwards.

Nevertheless, handles which do not comply with this last condition may be accepted if:

(a)	they have an independent return mechanism;

(b)	should the return mechanism fail, they cannot project more than 15 mm;

(c)	they comply, in such opened position, with the provisions of paragraph 5.4; and

(d)	their end surface area, when measured not more than 6,5 mm from the point projecting furthest, is not less than 150 mm2.

6.7. Wheels, wheel nuts, hub caps and wheel discs.

6.7.1.

The requirements of paragraph 5.4 shall not apply.

6.7.2.

The wheels, wheel nuts, hub caps and wheel discs shall not exhibit any pointed or sharp projections that extend beyond the external plane of the wheel rim. Wing nuts shall not be allowed.

6.7.3.

When the vehicle is travelling in a straight line, no part of the wheels other than the tyres, situated above the horizontal plane passing through their axis of rotation shall project beyond the vertical projection, in a horizontal plane of the external surface or structure. However, if functional requirements so warrant, wheel discs which cover wheel and hub nuts may project beyond the vertical projection of the external surface or structure on condition that the radius of curvature of the surface of the projecting part is not less than 30 mm and that the projection beyond the vertical projection of the external surface or structure in no case exceeds 30 mm.

6.8. Sheet-metal edges.

6.8.1.

Sheet-metal edges, such as gutter edges and the rails of sliding doors, shall not be permitted unless they are folded back or are fitted with a shield meeting the requirements of this Regulation which are applicable to it.

An unprotected edge shall be considered to be folded back either if it is folded back by approximately 180°, or if it is folded towards the bodywork in such a manner that it cannot be contacted by a sphere having a diameter of 100 mm.

The requirements of paragraph 5.4 shall not apply to the following sheet metal edges: rear edge of bonnet and front edge of rear luggage boot.

6.9. Body-panels.

6.9.1.

Folds in body panels may have a radius of curvature of less than 2,5 mm provided that it is not less than one-tenth of the height ‘H’ of the projection, measured in accordance with the method described in paragraph 1 of Annex 3.

6.10. Lateral air or rain deflectors.

6.10.1.

Lateral deflectors shall have a radius of curvature of at least 1 mm on edges capable of being directed outwards.

6.11. Jacking brackets and exhaust pipes.

6.11.1.

The jacking brackets and exhaust pipe(s) shall not project more than 10 mm beyond the vertical projection of the floor line lying vertically above them. As an exception to this requirement an exhaust pipe may project more than 10 mm beyond the vertical projection of the floor line, so long as it terminates in rounded edges, the minimum radius of curvature being 2,5 mm.

6.12. Air intake and outlet flaps.

6.12.1.

Air intake and outlet flaps shall meet the requirements of paragraphs 5.2, 5.3 and 5.4 in all positions of use.

6.13. Roof.

6.13.1.

Opening roofs shall be considered only in the closed position.

6.13.2.

Convertible vehicles shall be examined with the hood in both the raised and lowered positions.

6.13.2.1.

With the hood lowered, no examination shall be made of the vehicle inside an imaginary surface formed by the hood when in the raised position.

6.13.2.2.

Where a cover for the linkage of the hood when folded is provided as standard equipment, the examination shall be made with the cover in position.

6.14. Windows.

6.16. Luggage racks and ski racks.

6.16.1.

Luggage racks and ski racks shall be so attached to the vehicle that positive locking exists in at least one direction and that horizontal, longitudinal and transverse forces can be transmitted which are at least equal to the vertical load-bearing capacity of the rack as specified by its manufacturer. For the test of the luggage rack or ski rack fixed to the vehicle according to the manufacturer’s instructions, the test loads shall not be applied at one point only.

6.16.2.

Surfaces which, after installation of the rack, can be contacted by a sphere of 165 mm diameter shall not have parts with a radius of curvature less than 2,5 mm, unless the provisions of paragraph 6.3 can be applied.

6.16.3.

Fastening elements such as bolts that are tightened or loosened without tools shall not project more than 40 mm beyond the surfaces referred to in 6.16.2, the projection being determined according to the method prescribed in paragraph 2 of Annex 3, but using a sphere of 165 mm diameter in those cases where the method prescribed in paragraph 2.2 of that annex is employed.

6.17. Aerials

6.17.1.

Radio receiving and transmitting aerials shall be fitted to the vehicle in such a way that if their unattached end is less than 2 m from the road surface in any position of use specified by the manufacturer of the aerial, it shall be inside the zone bounded by the vertical planes which are 10 cm inside the extreme outer edge of the vehicle as defined in paragraph 2.7.

6.17.2.

Furthermore, aerials shall be so fitted to the vehicle, and if necessary their unattached ends so restricted, that no part of the aerials protrude beyond the extreme outer edge of the vehicle as defined in paragraph 2.7.

6.17.3.

Shafts of aerials may have radii of curvature of less than 2,5 mm. However, the unattached ends shall be fitted with fixed cappings, the radii of curvature of which are not less than 2,5 mm.

6.17.4.

The bases of aerials shall not project more than 40 mm when determined according to the procedure of Annex 3, paragraph 2.

6.17.4.1.

In cases where by the absence of a flexible shaft or part it is not possible to identify what the base is of an aerial this requirement is deemed to be met if, after a horizontal force of not more than 50 daN in forward and rearward direction is applied by a flat-ended ram of not more than 50 mm diameter at the most salient part of the aerial:

(a)	the aerial bends towards the support and does not project more than 40 mm, or

(b)	the aerial breaks off and the remaining part of the aerial does not show any sharp or dangerous part that can be contacted by the 100 mm sphere and does not project more than 40 mm.

6.17.4.2.

Paragraphs 6.17.4 and 6.17.4.1 shall not apply to aerials located behind the vertical transversal plane passing through the ‘R’ point of the driver, provided that the maximum projection of the aerial including its housing does not exceed 70 mm when determined according to the procedure of annex 3, paragraph 2.

If the aerial is located behind that vertical plane but projects more than 70 mm, paragraph 6.17.4.1 shall apply using a projection limit of 70 mm instead of 40 mm.

6.18. Assembly instructions.

6.18.1.

Luggage racks, ski racks and radio receiving or transmitting aerials that have been approved as separate technical units may not be offered for sale, sold or purchased unless accompanied by assembly instructions. The assembly instructions shall contain sufficient information to enable the approved components to be mounted on the vehicle in a manner that complies with the relevant provisions of paragraphs 5 and 6. In particular, the positions of use must be indicated for telescopic aerials.

ANNEX 3

Methods of determining the dimensions of projections and gaps

1. METHOD OF DETERMINING THE HEIGHT OF THE PROJECTION OF FOLDS IN BODY PANELS

1.1.

The height H of a projection is determined graphically by reference to the circumference of a 165 mm diameter circle, internally tangential to the external outline of the external surface at the section to be checked.

1.2.

H is the maximum value of the distance, measured along a straight line passing through the centre of the 165 mm diameter circle between the circumference of the aforesaid circle and the external contour of the projection (see Figure 1).

1.3.

In cases where it is not possible for a 100 mm diameter circle to contact externally part of the external outline of the external surface at the section under consideration, the surface outline in this area will be assumed to be that formed by the circumference of the 100 mm diameter circle between its tangent points with the external outline (see Figure 2).

1.4.

Drawings of the necessary sections through the external surface shall be provided by the manufacturer to allow the height of the projections referred to above to be measured.

Figure 1

Figure 2

2. METHOD OF DETERMINING THE DIMENSION OF THE PROJECTION OF A COMPONENT MOUNTED ON THE EXTERNAL SURFACE

2.1.

The dimension of the projection of a component which is mounted on a convex surface may be determined either directly or by reference to a drawing of an appropriate section of this component in its installed condition.

2.2.

If the dimension of the projection of a component which is mounted on a surface other than convex cannot be determined by simple measurement, it shall be determined by the maximum variation of the distance of the centre of a 100 mm diameter sphere from the nominal line of the panel when the sphere is moved over and is in constant contact with that component. Figure 3 shows an example of the use of this procedure.

3. METHOD OF DETERMINING THE PROJECTION OF HEADLAMP VISORS AND RIMS

3.1.

The projection from the external surface of the headlamp shall be measured horizontally from the point of contact of a 100 mm diameter sphere as shown in Figure 4.

4. METHOD OF DETERMINING THE DIMENSION OF A GAP OR THE SPACE BETWEEN ELEMENTS OF A GRILLE

4.1.

The dimension of a gap or space between elements of a grille shall be determined by the distance between two planes passing through the points of contact of the sphere and perpendicular to the line joining those points of contact. Figures 5 and 6 show examples of the use of this procedure.
