  • Patent number: 7963730
    Abstract: Apparatus for securing one or more wheelchairs to a vehicle includes a plurality of straps for holding the wheelchairs to the vehicle.

This allows the area to be utilized by other passengers when no wheelchairs are present and also facilitates ingress and egress of the wheelchairs. In the preferred embodiment, movable elements, which carry housings for wheelchair-engaging belts and passenger restraint belts, are mounted to the side wall of the vehicle for pivotal movement about vertical axes between storage positions and operative positions. The apparatus allows an operator to quickly and easily secure or release a passenger in a wheelchair and maintains the integrity of the straps.
