Abstract
Abstract Apparatus to be mounted on a cartop for raising a wheelchair from the driver's seat and orienting and engaging the wheelchair for transport on the roof. The supporting base is mounted on the roof with an overlying frame rotatably mounted to the base above the driver's position. The frame is biased to rotate outwardly of the car and a cable is used to raise the wheelchair, engage the frame for rotation and change the attitude of the chair so that it is flat-lying and engaged by the frame for transport.
