IV-23 FTA guidelines recommend either a static or dynamic test. The Access Board has deferred to NHTSA's expertise in establishing a viable outer bamer or retention device test. 10. Inner Roll Stop Strength (S5.4.8 and S6.5) - In addition to a wheelchair retention device 01 outer bamer, the proposed platform lift systems designed for buses and MPVs >4,450 kg (l0,CllOO lbs.) GVWR, are to have an Inner Roll Stop which prevents the wheelchair fiom inadvertently rolling or sliding off the inner edge (vehicle side) of the platform and prevents contact (pinchii 18) of occupant foot/toes between the WC lift platform and the vehicle structure. No inner roll stclp is required on personal use vehicles
IV-24 The lift is raised to the floor level of the bus or MPV, and to conform to requirements, the innc:r roll stop must prevent the wheelchair test device from being pinched between the lift and any other structure (e.g., bus body or door structure) throughout the range of passenger operation. This simulates the potential for pinching of WC user feetkoes. For personal use vehicles 4,540 kg (10,000 lbs.) GVWR ir which case the lift must be able to be loaded with the WC in a forward or rearward direction, whereas for personal use vehicles
