ABSTRACT:
A wheel chair hoist assembly for a vehicle having a body, a roof and a door opening comprises a support bar suspended within the body, with a mount tube reciprocally mounted upon the support bar. A boom having a retracted position within the body is located parallel to the support bar and at one end is secured to the mount tube. A motor operated winch assembly depends from the mount tube, and includes a drum with a cable wound thereon, and projected through the boom. The cable terminates in hooks to support a wheel chair. A reversible electric motor is supported upon the mount tube and drives a pinion in mesh with a stationary rack gear for reciprocally feeding the boom from its retracted position to an advanced position through the door opening. A manual remote control selectively connects the vehicle battery to the motor and to the winch assembly for alternately advancing and retracting the boom, and for alternately lowering and raising the wheel chair.
