  • Patent number: 3937376
    Abstract: A wheelchair support is attached to and extends from the bumper of an automobile and may be swung upwardly out of the way when not in use. A support frame for confining the wheels comprises members which define wheel recesses on opposite sides of an intermediate member, which carries an adjustable retaining member. The frame is supported on pivoted arms attached to a mounting frame having adjustable clamps which fit on and tighten to a conventional automobile bumper. A collapsed wheelchair is tilted upwards to place the large wheels in the well. Downward rotation of the wheelchair in the support frame causes the wheelchair frame to engage the retainer which secures the wheelchair in place.
