ABSTRACT:
A wheelchair lift for a van adapted to be installed into a recess formed into the rear of the van floor and bumper assembly. The lift includes a pair of spaced apart guide rails, each securely connectable into the sides of the recess so that they lie in spaced, longitudinally disposed verticle planes, the guide rails sloping diagonally downward toward the rear of the van. The lift also includes a movable platform whose central bed is horizontally disposed between spaced parallel side panels and adapted to receive a wheelchair or the like thereatop. A pair of spaced-apart rollers rotatably connected to each side panel engage within the guide rails to facilitate translation of the platform within the guide rails while maintaining the bed generally horizontal. A length of drive chain is connected at one end to each guide rail or van floor structure, each drive chain extending partially around a sprocket rotatably secured to each side panel, then extending to a drive device which controllably retracts and extends the drive chain to raise and lower the platform.
