Abstract: A device for loading and unloading a wheelchair into and out of a motor vehicle, consisting of a horizontal carriage track mounted transversely on the floor of the vehicle and extending the length of the compartment behind the front seat. A carriage block is slideably engaged with the carriage track and connected to a motor-actuated screw drive that causes it to slide along the track on command. An arm with a wheel-support track assembly conforming to the front wheels of a standard wheelchair is pivotally attached to the carriage block and can be extended to the outside of the vehicle to receive the folded wheelchair and move it in and out of the vehicle as the arm is retracted or extended as a result of the carriage block sliding across the track. The device is controlled by a single switch operable from the driver's seat.
