  • Patent number: 7160068
    Abstract: A flush-mounted securing device, preferably secured in a floor of a vehicle, to restrain a handicapped person in a wheelchair or scooter in a passenger vehicle. The securing device comprises a base plate, a top plate rotationally mounted relative to the base plate and including a series of belt or strap receptacles to fasten the transportable equipment, a low-profile shaft that axially supports the top plate for rotational movement against lateral forces between the top plane and base plate, a set of circumferentially disposed bearings (or slip rings) between the top plate and the base plate, and a retaining cap that secures the top plate to the base plate. Optionally, the device may include a locking/ratcheting mechanism to fixedly position the top plate at discrete rotational positions to assist passenger ingress/egress.

  • Patent number: 6568646
    Abstract: A wheelchair swivel platform that allows a standard, unmodified wheelchair or other non-swiveling chair and an occupant to swivel about an area of a workstation, in much the same way as a modem swivel office chair. The wheelchair swivel platform includes a top plate 16 and a bottom plate. The bottom plate serves as a base for the platform which lies on the floor to support the top plate 16. The top plate 16 swivels about the bottom plate while supporting the wheelchair. A rotation locking device prevents rotation of the platform during positioning of the wheelchair on and off the platform.
