ABSTRACT:
A powered 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 rear wheels are part of an articulating beam assembly and are positioned to provide access to the batteries from the rear of the wheelchair with ease.
