ABSTRACT:
A lightweight, optionally foldable wheelchair which allows the user maximum control over both travel direction and seat position. The wheelchair is driven manually by an arrangement of drive gears, which are actuated by a drive gear selector and operated by rotating a pair of opposed handwheels, one of which is contacted by each of the occupant's hands. One of four or more different gears may be selected, including a "Forward Only" and a "Reverse Only" gear, which allow travel only in the direction selected. A dual function shift lever supports the drive gear selector and may be activated to disengage the drive gears and engage a seat positioning gear. When the seat positioning gear is engaged, rotation of the handwheels by the wheelchair occupant will activate a seat raising mechanism which moves the seat from a horizontal sitting position to a substantially vertical position toward the rear of the wheelchair. The leg rests and foot rests fold and are engaged by the wheelchair frame so that they are guided away from the front of the chair, thus enabling the occupant to assume a standing position without changing the center of gravity of the chair.
