POWERED WHEELCHAIR CONFIGURATIONS AND RELATED METHODS OF USE

摘要

A wheelchair includes a frame, a chair, a pair of drive wheels, a pair of rear wheels, and a pair of front wheels. Each front wheel is part of a front arm assembly that is rigidly coupled to a drive via a mounting plate. The mounting plate is connected to the wheelchair frame by a pivot. The drives are transversely mounted. The batteries are disposed rearward of the drives. The wheelchair seat can be moved forward to provide access to the batteries without fully removing the wheelchair from the frame.
