ABSTRACT:
A vehicle having accommodations for a wheelchair includes an upper floor panel disposed within the vehicle and having a lowerable portion thereof adapted to support a wheelchair, and a lift mechanism mounted below the upper floor panel for lowering and raising the lowerable portion with respect to the upper floor panel. The lift mechanism comprises threaded holes on a protruding part of the lowerable panel. The threaded holes are engaged by a plurality of jack screws. The jack screws can be driven by a motor, sprocket and chain drive system. These accommodations allow a person in the wheelchair to be lowered to a level where they can comfortably see out the windows of the vehicle.
