These parts must not break or become detached under the tension set up by the prescribed load.

2.4.5.

Retractors.

Retractors shall fulfil the requirements specified below, including the tests for strength prescribed in 2.7.6.1 and 2.7.6.2.

2.4.5.1.

Automatically locking retractors.

2.4.5.1.1.

The strap of a safety belt equipped with an automatically locking retractor shall not move more than 30 mm between the locking positions of the retractor. After a rearward movement by the wearer, the belt must either remain in its initial position or return to that position automatically on subsequent forward movements by the wearer.

2.4.5.1.2.

If the retractor is part of a lap belt, the retracting force of the strap shall be not less than 0,7 daN when measured in the free length between the manikin and the retractor in accordance with 2.7.7.4. If the retractor is part of a diagonal strap the retracting force of the strap shall be not less than 0,2 daN and not more than 0,7 daN when similarly measured. If the strap passes through a guide or pulley, the retracting force shall be measured in the freelength between the manikin and the guide or pulley. If the assembly incorporates a device which, upon manual or automatic operation, prevents the strap from being completely retracted, such a device shall not be operated when the retracting force is assessed.

2.4.5.1.3.

The strap shall be withdrawn from the retractor and allowed to retract repeatedly, in accordance with the method described in 2.7.7.1, until 5 000 cycles of withdrawal and retraction have been completed. The retractor shall then be subjected to the corrosion test prescribed in 2.7.2 followed by the dust resistance test described in 2.7.7.3. It shall then satisfactorily complete a further 5 000 cycles after which it shall still meet the requirements of 2.4.5.1.1 and 2.4.5.1.2. After the above tests, the retractor shall still function correctly and stow the strap efficiently.

2.4.5.2.

Emergency locking retractors.

2.4.5.2.1.

An emergency locking retractor shall satisfy the following conditions when tested in accordance with 2.7.7.2. In the case of a single sensitivity, according to point 1.8.4.1, only the specifications regarding deceleration of the vehicle are valid.

In order to comply with the requirements of 2.4.5.2.1.2, a retractor shall be considered as satisfactory if, at the strap acceleration values prescribed in that point, it does not lock until at least the first 50 mm of strap has been unwound, starting at the length specified in 2.7.7.2.1.

2.4.5.2.4.

If the retractor is part of a lap belt, the retracting force of the strap shall be not less than 0,7 daN when measured in the free length between the manikin and the retractor, in accordance with 2.7.7.4. If the retractor is part of a diagonal strap; the retracting force of the strap shall be not less than 0,2 daN and not more than 0,7 daN when similarly measured. If the strap passes through a guide or pulley, the retracting force shall be measured in the free length between the manikin and the guide or pulley if the assembly incorporates a device which, upon manual or automatic operation, prevents the strap from being completely retracted, such a device shall not be operated when the retracting force is assessed.

2.4.5.2.5.

The strap shall be withdrawn from the retractor and allowed to retract repeatedly in accordance with the method described in 2.7.7.1 until 40 000 cycles of withdrawal and retraction have been completed. The retractor shall then be subjected to the corrosion test prescribed in 2.7.2 followed by the dust resistance test described in 2.7.7.3. It shall then satisfactorily complete a further 5 000 cycles of withdrawal and retraction, after which it shall still meet the requirements of 2.4.5.2.1, 2.4.5.2.2, 2.4.5.2.3 and 2.4.5.2.4.

However if the adjustment device for height consists of the anchorage itself, as permitted by Council Directive 76/115/EEC (4), the technical service responsible for the tests can, if it so wishes, apply the provisions of point 2.7.8.1 hereafter.

2.6.1.2.4.

In the case of a safety belt with a pre-loading device the minimum displacement specified in point 2.6.1.4.1 below may be reduced by half. For the purpose of this text, the pre-loading device shall be in operation.

2.6.1.3.

During this test, the following requirements shall be met:

2.6.1.3.1.

no part of a belt assembly or a restraint system securing the occupant shall break and no buckle or locking or displacement system shall unlock; and

2.6.1.3.2.

the forward displacement of the manikin shall be between 80 and 200 mm at pelvic level in the case of lap belts. In case of a harness belt the minimum displacement specified for the pelvis may be reduced by half. In the case of other types of belt, the forward displacement shall be between 80 and 200 mm at pelvic level and between 100 and 300 mm at torso level. These displacements are the displacements in relation to the measurement points shown in Annex VIII, Figure 6.

2.6.1.3.3.

In the case of a safety belt intended to be used in an outboard front seating position protected by an airbag in front of it, the displacement of the chest reference point may exceed that specified in paragraph 2.6.1.3.2 above if its speed at this value does not exceed 24 km/h.

2.6.1.4.

In the case of a restraint system:

2.6.1.4.1.

the movement of the chest reference point may exceed that specified in 2.6.1.3.2 if it can be shown, either by calculation or by a further test, that no part of the torso or the head of the manikin used in the dynamic test would have come into contact with any forward rigid part of the vehicle, apart from contact of the chest with the steering assembly, if the latter meets the requirements of Council Directive 74/297/EEC (5) and provided that contact does not occur at a speed higher than 24 km/h. For this assessment, the seat shall be considered to be in the position specified in 2.7.8.1.5.

2.6.1.4.2.

In vehicles where such devices are used, the displacement and locking systems enabling the occupants of all seats to leave the vehicle shall still be operable by hand after the dynamic test.

2.6.1.5.

By way of derogation, in the case of a restraint system, the displacements may be greater than those specified in point 2.6.1.3.2 in the case where the upper anchorage fitted to the seat profits by the derogation provided in point 5.5.4 of Annex I to Directive 76/115/EEC. Details of the restraint system concerned shall be included in the Addendum to the type-approval certificate referred to in Appendices 3 and 4 to Annex II.

2.6.2.

Strength after abrasion procedure.

2.6.2.1.

For both samples conditioned in conformity with 2.7.3.6, the breaking load shall be assessed in accordance with 2.5.2 and 2.7.6. It shall be at least equal to 75 % of the average of the breaking loads determined during tests on unabraded straps, and not less than the minimum load specified for the items being tested. The difference between the breaking loads of the two samples shall not exceed 20 % of the greater of the breaking loads measured. In the type 1 and type 2 procedures, the tensile-strength test shall be conducted on the strap samples only (point 2.7.5). In type 3 procedures, the tensile-strength test shall be conducted on the strap and relevant rigid parts (point 2.7.6).

2.6.2.2.

The items to be subjected to an abrasion procedure and the procedures to be followed are indicated in the following table. A new sample shall be used for each procedure.

2.7.

The breaking load shall be determined within 10 minutes of the strap's removal from the water.

2.7.3.6.

Conditioning by abrasion.

2.7.3.6.1.

The abrasion procedure shall be performed on every device in which the strap is in contact with a rigid part of the belt. However, the type 1 abrasion test (2.7.3.6.4.1) need not be carried out on the belt-adjusting device where the micro-slip test (2.7.4) shows that the strap slips less than half the prescribed amount. The setting on the test apparatus shall approximately maintain the relative position of strap and contact area.

2.7.3.6.2.

The samples to be subjected to abrasion shall be kept for a minimum of 24 hours in an atmosphere having a temperature of 20 ± 5 oC and a relative humidity of 65 ± 5 %. The room temperature during testing shall be between 15 and 30 oC.

2.7.3.6.3.

The table below sets out the requirements for each abrasion procedure:

The shift given in the fifth column of this table represents the amplitude of a back-and-forth motion applied to the strap.

2.7.3.6.4.

Particular procedure conditions.

2.7.3.6.4.1.

Type 1 procedure: for cases where the strap slides through an adjusting device.

The 2,5 daN load shall be vertically and permanently applied to one section of the strap.

The other section, set horizontally, shall be subjected to a back-and-forth motion.

The adjusting device shall be so placed that the horizontal section of the strap shall remain under load (see Annex XII, Figure 1).

2.7.3.6.4.2.

Type 2 procedure: in cases where the strap changes direction once in passing through a rigid part.

The angles which both strap ends make with each other must be as shown in Annex XII, Figure 2.

A permanent load of 0,5 daN must be applied. If the strap changes direction more than once on passing through a rigid part, the 0,5 daN load may be increased so as to achieve the prescribed 300 mm of strap movement through that rigid part.

2.7.3.6.4.3.

Type 3 procedure: for cases where the strap is fixed to a rigid part by sewing or similar means.

The total shift shall be 300 ± 20 mm and the 5 daN load shall be applied only during the time corresponding to a shift of 100 ± 20 mm for each half period (see Annex XII, Figure 3).

2.7.4.

Micro-slip test (see Annex XII, Figure 3).

2.7.4.1.

The components or devices to be subjected to the micro-slip test shall be kept for a minimum of 24 hours before testing in an atmosphere having a temperature of 20 ± 5 oC and a relative humidity of 65 ± 5 %.

The test shall be carried out at a temperature between 15 and 30 oC.

2.7.4.2.

It shall be ensured that the free section of the adjusting device points either up or down on the test bench, as in the vehicle.

2.7.4.3.

A 5 daN load shall be attached to the lower end of the section of strap.

The other end shall be subjected to a back-and-forth motion the total amplitude being 300 ± 20 mm (see figure).

2.7.4.4.

If there is a free end serving as reserve strap, it must in no way be fastened or clipped to the section under load.

2.7.4.5.

It shall be ensured that on the test bench the strap, in the slack position, descends in a concave curve from the adjusting device, as in the vehicle.

The 5 daN load applied on the test bench shall be guided vertically in such a way as to prevent the load swaying and the belt twisting.

The attachment shall be fixed to the 5 daN load as in the vehicle.

2.7.4.6.

Before the actual start of the test, a series of 20 cycles shall be completed so that the self-tightening system settles properly.

2.7.4.7.

1 000 cycles shall be completed at a frequency of 0,5 cycle per second, the total amplitude being 300 ± 20 mm. The 5 daN load shall be applied only during the time corresponding to a shift of 100 ± 20 mm for each half period.

2.7.5.

Test of breaking strength of strap (static test).

2.7.5.1.

The test shall be carried out each time on two new samples of strap, of sufficient length, conditioned in accordance with one of the provisions of 2.7.3.

2.7.5.2.

Each strap shall be gripped between the clamps of a tensile-testing machine. The clamps shall be so designed as to avoid breakage of the strap at or near the point of contact with the clamps. The speed of traverse shall be about 100 mm per minute. The free length of the sample between the clamps of the machine at the start of the test shall be 200 ± 40 mm.

2.7.5.3.

When the load reaches 980 daN, the width of the strap shall be measured without stopping the machine.

2.7.5.4.

The load shall then be increased until the strap breaks, and the breaking load shall be noted.

2.7.5.5.

If the strap slips or breaks at the point of contact with one of the clamps or within 10 mm of either of them, the test shall be invalid and a new test shall be carried out on another sample.

2.7.6.

Static test of belt components incorporating rigid parts.

2.7.6.1.

The buckle and strap adjusting device must be connected to the tensile-testing machine by their normal attachments and a load of 980 daN must be applied. In the case of harness belts, the buckle shall be connected to the testing apparatus by the straps which are attached to the buckle and the tongue or two tongues located in an approximately symmetrical way to the geometric centre of the buckle. If the buckle or adjusting device is part of the attachment or of the common component of a three-point strap, the buckle or adjusting device must be tested together with the attachment in accordance with point 2.7.6.2, except in the case of retractors with a return pulley at the upper strap anchorage. In this case the test load must be 980 daN and the length of strap remaining on the reel at the moment of locking must be as close as possible to 450 mm.

2.7.6.2.

The attachments and any belt adjustment devices for height shall be tested in the manner described in 2.7.6.1, but the load shall be 1 470 daN and, subject to the provisions of the second sentence of 2.7.8.1, shall be applied in the least favourable conditions likely to occur in a vehicle in which the belt is correctly installed. In the case of retractors, the test shall be performed with the strap completely unwound from the reel.

2.7.6.3.

Two samples of the complete belt assembly shall be placed in a low-temperature chamber at -10 ± 1 oC for two hours. Immediately after being removed from the chamber the mating parts of the buckle shall then be locked together manually.

2.7.6.4.

Two samples of the complete belt assembly shall be placed in a low-temperature chamber at a temperature of -10 ± 1 oC for two hours. All rigid items and parts made of plastic under test shall then be laid in turn on a flat steel surface (which has been kept with the samples in the low temperature chamber), placed on the horizontal surface of a compact rigid block with a mass of at least 100 kg; within 30 seconds of their being removed from the low-temperature chamber, an 18 kg steel mass shall be allowed to fall under gravity from a height of 300 mm onto the item. The impact face of the mass shall have a hardness of at least 45 HRC and take the form of a convex surface having a transverse radius of 10 mm and a longitudinal radius of 150 mm. One sample shall be tested with the axis of the curved bar in line with the strap, and the other sample shall be tested at 90 o to the strap.

2.7.6.5.

Buckles having parts common to two safety belts shall be loaded in such a way as to simulate the conditions of use in a vehicle with the seats in the mid-position of their adjustment. The direction of application of the load shall be established in accordance with 2.7.8.1. A load of 1 470 daN shall be applied simultaneously to each of the straps. Suitable apparatus for the above test is shown in Annex XI.

2.7.6.6.

When testing any manual adjusting device, the strap shall be drawn steadily through that device, having regard to normal conditions of use, at a rate of approximately 100 mm/s, and the maximum force shall be measured to the nearest 0,1 daN after the first 25 mm of strap movement. The test shall be carried out in both directions of strap travel through the adjusting device, the strap being cycled 10 times prior to measurement.

2.7.7.

Additional tests for retractors.

2.7.7.1.

Durability of retractor mechanism.

2.7.7.1.1.

The strap shall be withdrawn and allowed to retract for the required number of cycles at a rate of not more than 30 cycles per minute. In the case of emergency locking retractors, a snatch shall be introduced at each fifth cycle to lock the retractor. The snatches shall occur in equal numbers at each of five different extractions, namely, 90, 80, 75, 70 and 65 % of the total length of the strap on the retractor. However, where more than 900 mm is provided, the above percentages shall be related to the final 900 mm of strap which remain wound on the retractor.

2.7.7.1.2.

Suitable apparatus for the tests specified in 2.7.7.1.1 is shown in Annex IV.

2.7.7.2.

Locking of emergency locking retractors.

2.7.7.2.1.

The retractor shall be tested for locking when 300 ± 3 mm of strap remain wound on the retractor reel.

2.7.7.2.1.1.

In the case of a locking retractor actuated by strap movement, the extraction shall be in the direction in which it normally occurs when the retractor is installed in a vehicle.

2.7.7.2.1.2.

When retractors are being tested for sensitivity to vehicle deceleration, they shall be tested at the above extraction in both directions along two mutually perpendicular axes, which are horizontal if the retractor is to be installed in a vehicle as specified by the safety belt manufacturer. One of these test directions shall be chosen by the technical service conducting the approval test so as to give the most adverse conditions with respect to actuation of the locking mechanism.

2.7.7.2.2.

Suitable apparatus for the tests specified in 2.7.7.2.1 is described in Annex V. The design of any such test apparatus shall ensure that the required acceleration is achieved before the webbing is drawn out of the retractor by more than 5 mm and that the withdrawal takes place at an average rate of increase of acceleration of at least 25 g/s and not more than 150 g/s.

2.7.7.2.3.

For the purpose of testing the requirements of 2.4.5.2.1.3 and 2.4.5.2.1.4, the retractor shall be mounted on a horizontal table and the table tilted at a speed not exceeding 2 o per second until locking has occurred. The test shall be repeated in other directions so as to ensure that the requirements are fulfilled.

2.7.7.3.

Dust resistance.

2.7.7.3.1.

The retractor shall be placed in a test chamber, as shown in Annex VI. Its relative position shall be the same as that in which it is mounted in the vehicle. The test chamber shall contain a quantity of dust which meets the requirements of 2.7.7.3.2. 500 mm of the strap shall be extracted from the retractor and kept extracted, except that it shall be subjected to 10 complete cycles of retraction and withdrawal within one or two minutes after each agitation of the dust.

For a period of five hours, the dust shall be agitated every 20 minutes for five seconds by compressed air which is dry and free of lubricating oil, passing through an aperture 1,5 ± 0,1 mm in diameter at a gauge pressure of 5,5 × 105 ± 0,5 × 105 Pa.

2.7.7.3.2.

The dust used in the test described in 2.7.7.3.1 shall consist of about 1 kg of dry quartz. The particle size distribution shall be as follows:

(a)  passing through a 150 μm aperture, 104 μm wire diameter: 99 to 100 %;

(b)  passing through a 105 μm aperture, 64 μm wire diameter: 76 to 86 %;

(c)  passing through a 75 μm aperture, 52 μm wire diameter: 60 to 70 %.

2.7.7.4.

Retracting force.

2.7.7.4.1.

The retracting force shall be measured with the safety belt assembly fitted to a manikin, as in the dynamic test prescribed in 2.7.8. The strap tension shall be measured as close as possible to the points of contact with (but just clear of) the manikin, while the strap is being retracted at an approximate speed of 0,6 m per minute.

2.7.8.

Dynamic tests of the belt assembly or the restraint system.

2.7.8.1.

The belt assembly shall be mounted on a trolley equipped with the seat and the anchorages defined in Annex VII. If, however, the belt assembly is intended for a specific vehicle or for specific types of vehicle, the distances between the manikin and the anchorages shall be determined by the service conducting the tests, in accordance either with the fitting instructions supplied with the belt, or with the data supplied by the manufacturer of the vehicle. In that case, when the dynamic test has been carried out for a type of vehicle it need not be repeated for other types of vehicle where each anchorage point is less than 50 mm distant from the corresponding anchorage point of the tested belt. Alternatively, manufacturers may determine a hypothetical anchorage position for testing in order to enclose the maximum number of real anchorage points. If the belt is equipped with a belt adjustment device for height such as defined in 1.8.6 above, the position of the device and the means of securing it shall be the same as those of the vehicle design.

2.7.8.1.1.

In the case of a safety belt or restraint system with pre-loading devices relying on component parts other than those incorporated in the belt assembly itself, the belt assembly shall be mounted in conjunction with the necessary additional vehicle parts on the test trolley in the manner prescribed in points 2.7.8.1.2 to 2.7.8.1.6.

Alternatively, in the case where those devices cannot be tested on the test trolley, the manufacturer may demonstrate by a conventional frontal impact test at 50 km/h in conformity with ISO procedure 3560 (1975/11/1 — Road vehicles — Frontal fixed barrier collision test method) that the device complies with the requirements of the Directive.

If a safety belt forms part of an assembly which is the subject of an application for component type-approval as a restraint system, this safety belt must be mounted on that part of the vehicle structure to which it is normally fitted and that part must be attached to the test trolley as follows.

2.7.8.1.2.

The method used to secure the vehicle during the test shall not be such as to strengthen the anchorages of the seats or safety belts, or to lessen the normal deformation of the structure.

No forward part of the vehicle shall be present which, by limiting the forward movement of the manikin, apart from the feet, would reduce the load imposed on the restraint system during the test. The discarded parts of the structure can be replaced by parts of equivalent strength, provided that they do not hinder the forward movement of the manikin.

2.7.8.1.3.

A securing device shall be regarded as satisfactory if it produces no effect on an area extending over the whole width of the structure, and if the vehicle or the structure is blocked or immobilised in front at a distance of not less than 500 mm from the anchorage of the restraint system tested. At the rear, the structure shall be secured at a distance behind the anchorages which is sufficient to ensure that the requirements of 2.7.8.1.2 are fulfilled.

2.7.8.1.4.

The seats shall be adjusted and placed in the driving or travelling position considered by the technical service conducting the approval tests as providing the most adverse conditions of strength consistent with the positioning of the manikin in the vehicle. The positions of the seats shall be stated in the report. If the seat back is adjustable, it must be locked as specified by the manufacturer or, in the absence of any specification, locked in such a manner as to form an effective angle as near as possible to 25 o in the case of vehicles in categories M1 and N1 and as close as possible to 15 o in the case of vehicles of all other categories.

2.7.8.1.5.

For the purpose of assessing the requirements of 2.6.1.4.1, the seat shall be regarded as being in its most forward driving or travelling position appropriate to the dimensions of the manikin.

2.7.8.1.6.

All seats of the same group shall be tested simultaneously.

2.7.8.2.

The belt assembly must be attached to the manikin described in Annex VIII. A board 25 mm thick must be placed between the back of the manikin and the seat back. The belt must be firmly fastened around the manikin. The board must then be removed and the manikin so positioned that the whole length of its back is in contact with the seat back. A check shall be made to ensure that the mode of engagement of the two parts of the buckle entails no risks of reducing the reliability of locking.

2.7.8.3.

The free ends of the straps shall extend sufficiently far beyond the adjusting devices to allow for slip.

2.7.8.4.

The trolley shall then be propelled in such a way that, at the moment of impact, its free running speed is 50 ± 1 km/h and the manikin remains stable. The stopping distance of the trolley shall be 400 ± 50 mm. The trolley shall remain horizontal throughout deceleration. Deceleration of the trolley shall be achieved by using the apparatus shown in Annex VII or any other device giving equivalent results. The apparatus shall meet the performance requirements given in Annex IX.

2.7.8.5.

The trolley speed immediately before impact, the forward displacement of the manikin and the speed of the chest at a 300 mm displacement of the chest shall be measured.

2.7.8.6.

After impact, the belt assembly or restraint system and its rigid parts shall be inspected visually, without opening the buckle, in order to determine whether there has been any failure or breakage. In the case of restraint systems, a check shall also be made, after the test, to establish whether the parts of the vehicle structure which are attached to the trolley have undergone any permanent deformation. Any such deformation found shall be taken into account in any calculation made in accordance with 2.6.1.4.1.

2.7.9.

Buckle-opening test.

2.7.9.1.

Belt assemblies which have already undergone the dynamic test in accordance with 2.7.8, shall be used for this test.

2.7.9.2.

The belt assembly must be detached from the test trolley without the buckle being opened. A load shall be applied to the buckle by direct traction via the straps tied to it so that all the straps are subjected to the force of 60/n daN; ‘n’ is the number of straps linked to the buckle when it is in a locked position, its minimum is deemed to be 2. If the buckle is connected to a rigid part, account must be taken, when the force is applied, of the angle formed by the buckle and the rigid part during the dynamic test. At a speed of 400 ± 20 mm/min, a load must be applied to the geometric centre of the buckle-release button along a fixed axis running parallel to the initial direction of motion of the button. The buckle must be held in place by a rigid support when the force required to open the buckle is applied. The abovementioned load must not exceed the limit specified in point 2.4.2.5. The point of contact of the test assembly must be spherical, with a radius of 2,5 ± 0,1 mm. It must have a smooth metal surface.

2.7.9.3.

The buckle-opening force shall be measured and any failure of the buckle noted.

2.7.9.4.

After the buckle-opening test, the components of the belt assembly or restraint system which have undergone the tests prescribed in 2.7.8 shall be inspected and the extent of the damage sustained by the belt assembly or restraint system in the dynamic test shall be recorded in the test report.

2.7.10.

Additional tests on safety belts with pre-loading devices — Conditioning.

The pre-loading device may be separated from the safety belt to be tested and kept for 24 hours at a temperature of 60 ± 5 oC. The temperature shall then be raised to 100 ± 5 oC for two hours. Subsequently it shall be kept for 24 hours at a temperature of -30 ± 5 oC. After being removed from conditioning, the device shall warm up to ambient temperature. If it has been separated it shall be fitted again to the safety belt.

2.7.11.

Test report.

The test report shall record the results of the tests prescribed in 2.7 and, in particular, the trolley speed, the maximum forward displacement of the manikin, the position of the buckle, the buckle-opening force, and any failure or breakage. If, pursuant to 2.7.8.1, the anchorage requirements of Annex VII have not been respected, the report shall describe how the belt assembly or the restraint system is mounted and specify important angles and dimensions. The report, shall also mention any distortion or breakage of the buckle that occurred during the test.

In the case of a restraint system, the test report shall also specify the method of attaching the vehicle structure to the trolley, the position of the seats and the tilt of the seat backs. If the forward displacement of the manikin has exceeded the values prescribed in 2.6.1.3, the report shall state whether the requirements of 2.6.1.4.1 have been met.

2.8.

Conformity of production.

2.8.1.

Any safety belt or restraint system approved under this Directive shall be so manufactured as to conform to the type approved by meeting the requirements set forth in 2.3, 2.4, 2.5, 2.6 and 2.7 above.

2.8.2.

In order to verify that the requirements of point 2.8.1 are met, suitable controls of the production shall be carried out.

2.8.3.

As a general rule, measures to ensure the conformity of production shall be taken in accordance with the provisions laid down in Article 10 of Directive 70/156/EEC.

2.8.3.1.

Special provisions detailing the tests to be carried out and the test frequency are laid down in Annex XVI to this Directive or in Annex 16 of the document referred to in Annex XVII, as applicable.

2.9.

3.1.1.

With the exception of seating intended solely for use when the vehicle is stationary, the seats of vehicles belonging to category M1, M2 (of class III or B), M3 (of class III or B) and N shall be equipped with safety belts and/or restraint systems conforming to the requirements of this Directive.

Class I, II or A vehicles belonging to category M2 or M3 may be fitted with safety belts and/or restraint systems, provided they conform to the requirements of this Directive.

▼M6

3.1.2.

The types of safety belts or restraint systems for each seating position where installation is required shall be those specified in Annex XV (with which neither non-locking retractors (1.8.1) nor manually unlocking retractors (1.8.2) can be used). For all seating positions where lap belts type B are specified in Annex XV lap belts type Br3 are permitted except in the case that, in use, they retract to such an extent as to reduce comfort in a notable way after normal buckling up.

3.1.3.

If a vehicle is fitted with an integrated child restraint system it shall comply with the relevant requirements contained in Annex XVII.

3.1.4.

Where no safety belts are required any type of safety belt or restraint system conforming to this Directive may be provided at the choice of the manufacturer. A-type belts of the types permitted in Annex XV may be provided as an alternative to lap belts for those seating positions where lap belts are specified in Annex XV.

3.1.5.

On three point belts fitted with retractors, one retractor must operate at least on the diagonal strap.

3.1.6.

Except for vehicles of category M, an emergency locking retractor of type 4N (1.8.5) may be permitted instead of a retractor of type 4 (1.8.4) where it has been shown to the satisfaction of the services responsible for the tests that the fitting of a type 4 retractor would not be practical.

3.1.7.

For the front outboard and front centre seating positions shown in Annex XV and marked with the symbol *, lap belts of the type specified in that Annex shall be considered adequate where the windscreen is located outside the reference zone defined in Annex II to Directive 74/60/EEC.

As regards safety belts, the windscreen is considered as part of the reference zone when it is capable of entering into static contact with the test apparatus according to the method described in Annex II to Directive 74/60/EEC.

3.1.8.

For all seating positions in Annex XV marked with the symbol #, lap belts of the types specified in Annex XV must be provided where an ‘exposed seating position’ as defined in 3.1.9 exists.

3.1.9.

An ‘exposed seating position’ is one where there is no ‘protective screen’ in front of the seat within the following defined space:

— between two horizontal planes, one through the H-point and the other 400 mm above it,

— between two vertical longitudinal planes which are symmetrical in relation to the H-point and are 400 mm apart,

— behind a transverse vertical plane 1,30 m from the H-point.

For the purpose of this requirement ‘protective screen’ means a surface of suitable strength and showing no discontinuities such that, if a sphere of 165 mm diameter is geometrically projected in a longitudinal horizontal direction through any point of the space defined above and through the centre of the sphere, nowhere in the protective screen is there any aperture through which the geometrical projection of the sphere could be passed.

A seat is considered to be in an ‘exposed seating position’, if the protective screens within the space defined above have a combined surface area of less than 800 cm2.

3.1.10.

At every seating position in Annex XV marked with the symbol , three-point belts of a type specified in Annex XV shall be provided unless one of the following conditions is fulfilled:

— there is a seat or other vehicle parts conforming to point 3.5 of Appendix 1 of Annex III to Council Directive 74/408/EEC (7) directly in front, or

— no part of the vehicle is in or, when the vehicle is in motion, capable of being in the reference zone, or

— parts of the vehicle within the said reference zone comply with the energy absorbing requirements set out in Appendix 6 of Annex III to Directive 74/408/EEC,

in which case two-point belts of a type specified in Annex XV may be provided.

3.1.11.

Save as provided by point 3.1.12 every passenger seating position which is fitted with an air bag shall be provided with a warning against the use of a rearward-facing child restraint on that seat. The warning label, in the form of a pictogram which may include explanatory text, shall be durably affixed and located such that it is easily visible in front of a person about to install a rearward-facing child restraint on the seat in question. An example of a possible design of pictogram is shown in Figure 1. A permanent reference should be visible at all times, in case the warning is not visible when the door is closed.

3.1.12.

The requirements of point 3.1.11 shall not apply if the vehicle is fitted with a mechanism which senses automatically the presence of a rearward-facing child restraint, and ensures that the air bag will not be deployed when such a child restraint system is fitted.

3.1.13.

In the case of seats capable of being turned to or placed in other orientations, for use when the vehicle is stationary, the requirements of point 3.1.1 shall only apply to those orientations designated for normal use when the vehicle is travelling on a road, in accordance with this Directive. A note to this effect shall be included in the information document.

3.2.

General requirements.

3.2.1.

Safety belts and restraint systems shall be fixed to anchorages conforming to the specifications of Directive 76/115/EEC.

3.2.2.

The safety belts and the restraint systems shall be so installed that, when properly worn, they will work satisfactorily and reduce the risk of bodily injury in the event of an accident. In particular they shall be so installed that:

3.2.2.1.

the straps are not liable to assume a dangerous configuration;

3.2.2.2.

that the danger of a correctly positioned belt slipping from the shoulder of a wearer as a result of his/her forward movement is reduced to a minimum;

3.2.2.3.

the risk of the strap deteriorating through contact with sharp rigid parts of the vehicle or seat structure is reduced to a minimum.

3.2.2.4.

The design and installation of every safety belt provided for each seating position shall be such as to be readily available for use. Furthermore, where the complete seat or the seat cushion and/or the seat back can be folded to permit access to the rear of the vehicle or to carry goods or luggage, after folding and restoring those seats to the seating position, the safety belts provided for those seats shall be accessible for use or be easily recovered from under or behind the seat by one person, according to instructions in the vehicle users handbook, without the need for that person to have training or practice.

3.2.2.5.

The technical service shall verify that, with the buckle tongue engaged in the buckle and no occupant in the seat:

— the possible slack in the belt does not prevent the correct installation of child restraint systems recommended by the manufacturer, and

— in the case of three-point belts, a tension of at least 50 N can be established in the lap section of the belt by external application of tension in the diagonal section of the belt.

3.3.

Special requirements for rigid parts incorporated in safety belts or restraint systems.

3.3.1.

Rigid parts, such as the buckles, adjusting devices and attachments, shall not increase the risk of bodily injury to the wearer or to other occupants of the vehicle in the event of an accident.

3.3.2.

The device for releasing the buckle shall be clearly visible to and within easy reach of the wearer and shall be so designed that it cannot be opened inadvertently or accidentally. The buckle shall also be located in such a position that it is readily accessible to a rescuer needing to release the wearer in an emergency.

The buckle shall be so installed that, both when not under load and when sustaining the wearer's weight, it is capable of being released by the wearer with a single simple movement of either hand in one direction. In the case of safety belts or restraint systems for front outboard seating positions, except if these are harness belts, the buckle shall also be capable of being locked in the same manner.

A check shall be made to ensure that, if the buckle is in contact with the wearer, the contact surface satisfies the requirements of 2.4.2.1 of this Annex.

3.3.3.

When the belt is being worn, it shall either adjust automatically to fit the wearer or be so designed that the manual adjusting device is readily accessible to the wearer when seated and is convenient and easy to use. It shall also be possible for it to be tightened with one hand to suit the build of the wearer and the position of the vehicle seat.

3.3.4.

Safety belts or restraint systems incorporating retractors shall be so installed that the retractors are able to operate correctly and stow the strap efficiently.

3.4.

In order to inform the vehicle user(s) of the provision made for the transport of children, the requirements of Annex XVIII shall be met.

4.

table 2: references, names, materials and principal dimensions of the components of the manikin.

1.2.

Description of the manikin

1.2.1.

Lower leg structure (see Figures 3 and 4)

The lower leg structure consists of three components:

— a sole plate (30),

— a shin tube (29),

— a knee tube (26).

The knee tube has two lugs which limit the movement of the lower leg in relation to the thigh.

The lower leg can rotate rearwards about 120o from the straight position.

1.2.2.

Thigh structure (see Figures 3 and 4)

The thigh structure consists of three components:

— a knee tube (22),

— a thigh bar (21),

— a hip tube (20).

Movement of the knee is limited by two cut-outs in the knee tube (22) which engage with the lugs of the leg.

1.2.3.

Torso structure (see Figures 1 and 2)

The torso structure consists of the following components:

— a hip tube (2),

— a roller chain (4),

— ribs (6) and (7),

— a sternum (8),

— chain attachments (3 and, partly, 7 and 8).

1.2.4.

Neck (see Figures 1 and 2)

The neck consists of seven polyurethane discs (9). The degree of stiffness of the neck can be adjusted by means of a chain tensioner.

1.2.5.

Head (see Figures 1 and 2)

The head (15) is hollow; the polyurethane is reinforced by steel bands (17). The chain tensioner which enables the neck to be adjusted consists of a poiyamide block (10), a tubular spacer (11) and a tensioning component (12 and 13). The head can rotate at the joint berween the first and second cervical vertebrae (the atlas-axis joint), which consists of an adjuster assembly (14 and 18), a spacer (16) and a polyamide block (10).

1.2.6.

Knee joint (see Figure 4)

The lower leg and thighs are connected by a tube (27) and a tensioner (28).

1.2.7.

Hip joint (see Figure 4)

The thighs and torso are connected by a tube (23), friction plates (24) and a tensioner (25).

1.2.8.

Polyurethane

1.2.9.

Overall

The manikin is covered by a special overall.

2.

CORRECTION OF THE MASS

In order to calibrate the manikin to certain values and its total mass, the mass distribution must be adjusted by means of six correction weights of 1 kg each which can be fitted to the hip joint. Six other polyurethane weights of 1 kg each can be fitted to the back of the torso.

3.

CUSHION

A cushion shall be positioned between the chest of the manikin and the overall. This cushion must be made of polyethylene foam complying with the following specification:

— hardness: 7 to 10 shore A

— thickness: 25 ± 5 mm.

It shall be replaceable.

4.

ADJUSTMENT OF THE JOINTS

4.1.

General

In order to achieve reproducible results, it is necessary to specify and control the friction at each joint.

4.2.

Knee joint:

tighten the knee joint;

set the thigh and lower leg vertical;

rotate the lower leg through 30o;

gradually slacken the tensioner until the lower leg starts to fall under its own weight;

lock the tensioner in this position.

4.3.

Hip joints:

increase the rigidity of the hip ioints for the purposes of adjustment;

place the thighs in a horizontal position and the torso in a vertical position;

rotate the torso forwards until it forms an angle of 60o with the thighs;

gradually slacken the tensioner until the torso starts to fall under its own weight;

lock the tensioner in this position.

4.4.

Atlas-axis joint:

adjust the atlas-axis joint so that it just resists its own weight in the fore and aft directions.

4.5.

Neck:

the neck can be adjusted by means of the chain tensioner (13);

when the neck is adjusted, the upper end of the tensioner shall be displaced between 40 and 60 mm when subjected to a horizontal load of 10 daN.

TEST APPARATUS

1.1.

The apparatus shall consist of a mist chamber, a salt solution reservoir, a supply of suitably conditioned compressed air, one or more atomising nozzles, sample supports, provision for heating the chamber and the necessary means of control. The size and constructional details of the apparatus shall be optional, provided that the test conditions are met.

1.2.

It is important to ensure that drops of solution accumulated on the ceiling or cover of the chamber do not fall on test samples, and

1.3.

that drops of solution which fall from test samples are not returned to the reservoir and then atomised again.

1.4.

The apparatus shall not be constructed of materials which affect the corrosiveness of the mist.

2.

LOCATION OF TEST SAMPLES IN THE MIST CABINET

2.1.

Samples, except retractors, shall be supported or suspended between 15o and 30o from the vertical and preferably parallel to the principal direction of horizontal flow of mist through the chamber, as determined, in relation to the dominant surface being tested.

2.2.

Retractors shall be supported or suspended in such a manner that the axes of the reels for storing the strap are normal to the principal direction of horizontal flow of mist through the chamber. The strap opening in the retractor shall also be facing this principal direction.

2.3.

Each sample shall be so placed as to permit the mist to settle freely on all samples.

2.4.

Each sample shall be so placed as to prevent salt solution dripping from one sample to another.

3.

SALT SOLUTION

3.1.

The salt solution shall be prepared by dissolving 5 ± 1 parts by mass of sodium chloride in 95 parts of distilled water. The salt shall be sodium chloride substantially free from nickel and copper and containing in the dry state not more than 0,1 % of sodium iodide and not more than 0,3 % of impurities in total.

3.2.

The solution shall be such that when atomised at 35 oC the collected solution is in the pH range of 6,5 to 7,2.

4.

AIR SUPPLY

The compressed air supply to the nozzle or nozzles for atomising the salt solution shall be free from oil and impurities, and maintained at a pressure of between 70 kN/m2 and 170 kN/m2.

5.

CONDITIONS IN THE MIST CHAMBER

5.1.

The exposure zone of the mist chamber shall be maintained at 35 ± 5 oC. At least two clean mist collectors shall be placed within the exposure zone to prevent drops of solution from the test samples or any other source from accumulating. The collectors shall be placed near the test samples, one as near as possible to the nozzles and the other as far away as possible from the nozzles. The mist shall be such that, for each 80 cm2 of horizontal collecting area, an average of between 1,0 and 2,0 ml of solution per hour is collected in each collector when measured over at least 16 hours.

5.2.

The nozzle or nozzles shall be directed or baffled in such a manner that the spray does not strike directly onto the test samples.
