A wheelchair space must be fitted with—
(a)a wheelchair and wheelchair user restraint system complying with item 19 of Directive 2007/46/EC, Annex XI, Appendix 3; or
(b)a restraint system comprising—
(i)a four point wheelchair tie-down system suitable for general wheelchair application; and
(ii)a wheelchair user restraint system comprising a minimum of three anchorage points to provide a pelvic and upper torso restraint system.
A wheelchair tie-down device must comply with ISO 10542 and be marked accordingly.
The geometry of the wheelchair tie-down and occupant restraint system anchorages and webbing must comply with ISO 10542. A surrogate wheelchair as defined in ISO 10542 or equivalent must be used for this purpose.
A static test must be conducted on the anchorage points for both the wheelchair tie-downs and occupant restraints in accordance with the following requirements—
(c)The tests must be conducted on a vehicle or a representative section of a vehicle structure including any vehicle fittings that are likely to contribute to the strength or rigidity of the structure;
(d)The forces specified in 5 below must be applied by means of a surrogate wheelchair of adequate strength as defined in ISO 10542, or equivalent, with attachment points for the front and rear tie-downs and reproducing the geometry of the wheelchair tie-down system;
(e)The forces specified in 6 below must be applied by means of a traction device specified in paragraph 5.3.4 of Annex I to Directive 76/115/EEC as last amended by Directive 96/38/EC and supported on the surrogate wheelchair defined in (b) above;
(f)The forces in (b) and (c) above must be applied simultaneously in the forward direction at an angle of 10° ± 5° above the horizontal plane. The force in (b) shall be applied at a height of not less than 200 mm and not more than 300 mm measured vertically above the floor of the wheelchair space;
(g)The force in 5(b) must be applied in the rearward direction at an angle of 10° ± 5° above the horizontal plane at a height of not less than 200 mm and not more than 300 mm measured vertically above the floor of the wheelchair space;
(h)All forces must be applied as rapidly as possible through the central vertical axis of the wheelchair and wheelchair space; and
(i)All forces must be maintained for a period of not less than 0.2 seconds.
For test purposes the components comprising the wheelchair tie-down and occupant restraint devices may be replaced with components suitable for test purposes having a similar function.
The force applied to the surrogate wheelchair:
(j)in the forward direction to be 24.50 kN;
(k)in the rearward direction to be 12.25 kN.
The forces to be those specified in paragraph 5.4 of Annex I to Directive 76/115/EEC as amended by Directive 96/38/EC.
The anchorages will meet the test performance requirements if—
(l)no part of the system has failed, or become detached during the test;
(m)no part of the anchorage system has deformed to such an extent that sharp edges or protrusion may cause injury.
