Regulation 97C

at least 2 anchorage points; and

a lap belt,which meet the specifications as specified in the Road Traffic (Motor Vehicles, Seat Belts) Rules (R 15).

comply with the dynamic test carried out in accordance with paragraph (6) (when the wheelchair restraint system is attached to anchorages in accordance with paragraph (6)(a)(i)) and be securely attached to vehicle anchorages which comply with the static test carried out in accordance with paragraph (5); or

be securely attached to vehicle anchorages such that the combination of restraint and anchorages comply with the dynamic test carried out in accordance with paragraph (6) (when the wheelchair restraint system is attached to anchorages in accordance with paragraph (6)(a)(ii)).

a representative section of the vehicle structure together with any fitting provided in the vehicle which is likely to contribute to the strength or rigidity of the structure shall be used;

in the case of anchorages provided for a wheelchair restraint system fitted to a vehicle with maximum laden weight not exceeding 5,000 kilograms —

a force of 11,100 N shall be applied in the longitudinal plane of the vehicle and towards the front of the vehicle; and

a force of 5,500 N shall be applied in the longitudinal plane of the vehicle and towards the rear of the vehicle;

in the case of anchorages provided for a wheelchair restraint system fitted to a vehicle with maximum laden weight exceeding 5,000 kilograms —

a force of 7,400 N shall be applied in the longitudinal plane of the vehicle and towards the front of the vehicle; and

a force of 3,700 N shall be applied in the longitudinal plane of the vehicle and towards the rear of the vehicle; and

the forces specified in sub-paragraph (b) or (c) shall be —

applied by means of a device reproducing the geometry of the wheelchair restraint system;

applied at a height of not less than 200 millimetres and not more than 300 millimetres measured vertically from the floor of the wheelchair space;

applied simultaneously, at an angle of 10°± 5 above the horizontal plane, in the forward direction and rearward direction;

applied as rapidly as possible through the central vertical axis of the wheelchair space; and

maintained for a period of not less than 0.2 seconds.

the wheelchair restraint system shall be attached to —

anchorages fixed to a test rig which represents the geometry of the anchorages in a vehicle; or

anchorages forming part of a representative section of the vehicle structure together with any fitting provided in the vehicle which is likely to contribute to the strength or rigidity of the structure;

a representative wheelchair test trolley of mass 85 kilograms shall, from a speed of between 48 km/h and 50 km/h to rest, be subject to a deceleration-time pulse in the forward direction which —

exceeds 15 g for a cumulative period of at least 0.04 seconds;

exceeds 20 g for a cumulative period of at least 0.015 seconds;

exceeds 15 g but does not exceed 28 g, for a cumulative period of not more than 0.08 seconds;

is for an overall duration of at least 0.075 seconds and not more than 0.12 seconds; and

a representative wheelchair test trolley of mass 85 kilograms shall, from a speed of between 48 km/h and 50 km/h to rest, be subject to a deceleration-time pulse in the rearward direction which —

exceeds 5 g for a cumulative period of at least 0.015 seconds; and

exceeds 5 g but does not exceed 8 g, for a cumulative period of not more than 0.02 seconds.

no part of the wheelchair restraint system has failed, or has become detached from its anchorage or from the vehicle, during the test;

mechanisms to release the wheelchair and wheelchair user are capable of release after completion of the test;

the wheelchair does not move more than 200 millimetres in the longitudinal plane of the vehicle during the test; and

no part of the wheelchair restraint system is deformed to such an extent after completion of the test that, because of any sharp edge or other protrusion, the part is capable of causing injury.
