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 the 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 the 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 co-ordinate 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.

‘Fiducial marks’ are physical points (holes, surfaces, marks or indentations) on the vehicle body as defined by the manufacturer;

2.11.

‘Vehicle measuring attitude’ means the position of the vehicle as defined by the co-ordinates 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 co-ordinates 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 co-ordinates 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 co-ordinates 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 co-ordinates, 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 5o of the design 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 oC to ensure that the seat material reached 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 then be 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 the 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 seat-back. Rock the 3-D H machine from side to side through a 10o arc (5o 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 spirits 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 paragraph 4.12.

4.14.

Take all measurements:

4.14.1.

The co-ordinates 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.

The manufacturer shall be responsible for the conformity of production procedures and for that purpose must in particular:

4.1.1.

Ensure the existence of effective procedures so that the quality of the products can be inspected,

4.1.2.

Have access to the testing equipment needed to inspect the conformity of each product,

4.1.3.

Ensure that the test results are recorded and that the documents remain available for a time period of 10 years after the tests,

4.1.4.

Demonstrate that the samples tested are a reliable measure of the performance of the batch (examples of sampling methods according to batch production are given below).

4.1.5.

Analyse results of tests in order to verify and ensure the stability of the barrier characteristics, making allowance for variations of an industrial production, such as temperature, raw materials quality, time of immersion in chemical, chemical concentration, neutralisation etc, and the control of the processed material in order to remove any residue from the processing,

4.1.6.

Ensure that any set of samples or test pieces giving evidence of non-conformity gives rise to a further sampling and test. All the necessary steps must be taken to restore conformity of the corresponding production.

4.2.

The manufacturer's level of certification must be at least ISO 9002 standard.

4.3.

Minimum conditions for the control of production: the holder of an agreement will ensure the control of conformity following the methods hereunder described.

4.4.   Examples of sampling according to batch

4.4.1.

If several examples of one block type are constructed from one original block of aluminium honeycomb and are all treated in the same treatment bath (parallel production), one of these examples could be chosen as the sample, provided care is taken to ensure that the treatment is evenly applied to all blocks. If not, it may be necessary to select more than one sample.

4.4.2.

If a limited number of similar blocks (say three to twenty) are treated in the same bath (serial production), then the first and last block treated in a batch, all of which are constructed from the same original block of aluminium honeycomb, should be taken as representative samples. If the first sample complies with the requirements but the last does not, it may be necessary to take further samples from earlier in the production until a sample that does comply is found. Only the blocks between these samples should be considered to be approved.

4.4.3.

Once experience is gained with the consistency of production control, it may be possible to combine both sampling approaches, so that more than one groups of parallel production can be considered to be a batch provided samples from the first and last production groups comply.

5.   STATIC TESTS

5.1.

One or more samples (according to the batch method) taken from each batch of processed honeycomb core shall be tested, according to the following test procedure:

5.2.

The sample size of the aluminium honeycomb for static tests shall be the size of a normal block of the impactor, that is to say 250 mm × 500 mm × 440 mm for top row and 250 mm × 500 mm × 500 mm for the bottom row.

5.3.

The samples should be compressed between two parallel loading plates which are at least 20 mm larger that the block cross section.

5.4.

The compression speed shall be 100 millimetres per minute, with a tolerance of 5 per cent.

5.5.

The data acquisition for static compression shall be sampled at a minimum of 5 Hz.

The load cell impact plate area centres shall align with those of the six impact zones of the mobile deformable barrier face. Their edges shall clear adjacent areas by 20 mm such that, within the tolerance of impact alignment of the MDB, the impact zones will not contact the adjacent impact plate areas. Cell mounting and plate surfaces shall be in accordance with the requirements set out in the annex to standard ISO 6487:1987.

6.1.2.3.

Surface protection, comprising a plywood face (thickness: 12 ± 1 mm), is added to each load cell plate such that it shall not degrade the transducer responses.

6.1.2.4.

The rigid wall shall be either anchored in the ground or placed on the ground with, if necessary, additional arresting devices to limit its deflection. A rigid wall (to which the load cells are attached) having different characteristics but giving results that are at least equally conclusive may be used.

6.2.   Propulsion of the mobile deformable barrier

At the moment of impact the mobile deformable barrier shall no longer be subject to the action of any additional steering or propelling device. It shall reach the obstacle on a course perpendicular to the front surface of the dynamometric wall. Impact alignment shall be accurate to within 10 mm.

6.3.   Measuring instruments

6.3.1.   Speed

The impact speed shall be 35 ± 0,5 km/h the instrument used to record the speed on impact shall be accurate to within 0,1 percent.

6.5.   General specifications of the impactor

6.5.1.

The suitability of an impactor as regards the dynamic test requirements shall be confirmed when the outputs from the six load cell plates each produce signals complying with the requirements indicated in this annex.

6.5.2.

Impactors shall carry consecutive serial numbers which are stamped, etched or otherwise permanently attached, from which the batches for the individual blocks and the date of manufacture can be established.

6.6.   Data processing procedure

6.6.1.

Raw data: At time T = T0, all offsets should be removed from the data. The method by which offsets are removed shall be recorded in the test report.

6.6.2.   Filtering

6.6.2.1.

The raw data will be filtered prior to processing/calculations.

6.6.2.2.

Accelerometer data for integration will be filtered to CFC 180, ISO 6487:1987.

6.6.2.3.

Accelerometer data for impulse calculations will be filtered to CFC 60, ISO 6487:1987.

6.6.2.4.

Load cell data will be filtered to CFC 60, ISO 6487:1987.

6.6.3.   Calculation of MDB face deflection

6.6.3.1.

Accelerometer data from all three accelerometers individually (after filtering at CFC 180), will be integrated twice to obtain deflection of the barrier deformable element.

6.6.3.2.

The initial conditions for deflection are:

6.6.3.2.1.

velocity = impact velocity (from speed measuring device).

6.6.3.2.2.

deflection = 0

6.6.3.3.

The deflection at the left hand side, mid-line and right hand side of the mobile deformable barrier will be plotted with respect to time.

6.6.3.4.

The maximum deflection calculated from each of the three accelerometers should be within 10 mm. If it is not the case, then the outlier should be removed and difference between the deflection calculated from the remaining two accelerometers checked to ensure that it is within 10 mm.

6.6.3.5.

If the deflections as measured by the left hand side, right hand side and mid-line accelerometers are within 10 mm, then the mean acceleration of the three accelerometers should be used to calculate the deflection of the barrier face.

6.6.3.6.

If the deflection from only two accelerometers meets the 10 mm requirement, then the mean acceleration from these two accelerometers should be used to calculate the deflection for the barrier face.

6.6.3.7.

If the deflections calculated from all three accelerometers (left hand side, right hand side and mid-line) are NOT within the 10 mm requirement, then the raw data should be reviewed to determine the causes of such large variation. In this case the individual test house will determine which accelerometer data should be used to determine mobile deformable barrier deflection or whether none of the accelerometer readings can be used, in which case, the certification test must be repeated. A full explanation should be given in the test report.

6.6.3.8.

The mean deflection-time data will be combined with the load cell wall force-time data to generate the force-deflection result for each block.

6.6.4.   Calculation of energy

The absorbed energy for each block and for the whole MDB face should be calculated up to the point of peak deflection of the barrier.

where:

t0	is the time of first contact
t1	is the time where the trolley comes to rest, i.e. where u = 0.
s	is the deflection of the trolley deformable element calculated according to paragraph 6.6.3.

6.6.5.   Verification of dynamic force data

6.6.5.1.

Compare the total impulse, I, calculated from the integration of the total force over the period of contact, with the momentum change over that period (M*)V).

6.6.5.2.

Compare the total energy change to the change in kinetic energy of the MDB, given by: where Vi is the impact velocity and M the whole mass of the MDB If the momentum change (M*)V) is not equal to the total impulse (I) ± 5 per cent, or if the total energy absorbed (E En) is not equal to the kinetic energy, EK ± 5 per cent, then the test data must be examined to determine the cause of this error.

(1)  The amounts of energy indicated are the amounts of energy dissipated by the system when the extent to which the impactor is crushed is greatest.

(2)  All dimensions are in mm. The tolerances on the dimensions of the blocks allow for the difficulties of measuring cut aluminium honeycomb. The tolerance on the overall dimension of the impactor is less than that for the individual blocks since the honeycomb blocks can be adjusted, with overlap if necessary, to maintain a more closely defined impact face dimension.

ANNEX 7

INSTALLATION OF THE SIDE IMPACT DUMMY

1.   GENERAL

1.1.

The side impact dummy as described in annex 6 of this Regulation is to be used according the following installation procedure.

2.   INSTALLATION

2.1.

Adjust the knee and ankle joints so that they just support the lower leg and the foot when extended horizontally (1 to 2 g — adjustment).

2.2.

Check if the dummy is adapted to the desired impact direction.

2.3.

The dummy shall be clothed in a form-fitting cotton stretch mid-calf length pant and may be clothed in a form-fitting cotton stretch shirt with short sleeves.

2.4.

Each foot shall be equipped with a shoe.

2.5.

Place the dummy in the outboard front seat on the impacted side as described in the side impact test procedure specification.

2.6.

The plane of symmetry of the dummy shall coincide with the vertical median plane of the specified seating position.

2.7.

The pelvis of the dummy shall be positioned such that a lateral line passing through the dummy H-points is perpendicular to the longitudinal centre plane of the seat. The line through the dummy H-points shall be horizontal with a maximum inclination of ± 2 degrees (1). The correct position of the dummy pelvis can be checked relative to the H-point of the H-point Manikin by using the M3 holes in the H-point back plates at each side of the ES-2 pelvis. The M3 holes are indicated with ‘Hm’. The ‘Hm’ position should be in a circle with a radius of 10 mm round the H-point of the H-point Manikin.

2.8.

The upper torso shall be bent forward and then laid back firmly against the seat back (see note 14). The shoulders of the dummy shall be set fully rearward.

2.9.

Irrespective of the seating position of the dummy, the angle between the upper arm and the torso arm reference line on each side shall be 40 ± 5 degrees. The torso arm reference line is defined as the intersection of the plane tangential to the front surface of the ribs and the longitudinal vertical plane of the dummy containing the arm.

2.10.

For the driver's seating position, without inducing pelvis or torso movement, place the right foot of the dummy on the non-depressed accelerator pedal with the heel resting as far forward as possible on the floor-pan. Set the left foot perpendicular to the lower leg with the heel resting on the floor-pan in the same lateral line as the right heel. Set the knees of the dummy such that their outside surfaces are 150 ± 10 mm from the plane of symmetry of the dummy. If possible within these constraints, place the thighs of the dummy in contact with the seat cushion.

2.11.

For other seating positions, without inducing pelvis or torso movement, place the heels of the dummy as far forward as possible on the floor-pan without compressing the seat cushion more than the compression due to the weight of the leg. Set the knees of the dummy such that their outside surfaces are 150 ± 10 mm from the plane of symmetry of the dummy.

---

(1)  The dummy can be equipped with tilt sensors in the thorax and the pelvis. These instruments can help to obtain the desired position.
