ABSTRACT:
This wheelchair incorporates a unitary supporting frame for the drive wheels and swivalable casters, and an adjustable seating assembly. The supporting frame is adjustable to change the wheelbase, track, and frame pitch and thereby shift the user's center of gravity and orientation with respect to the wheels. In a preferred embodiment provision is made for adjusting and maintaining the alignment of the wheels and casters. The seating assembly allows the seat and seat back to be positioned independently to suit the user's size, posture, balance, and other physical characteristics. A powered seat mount allows the user to raise and lower the seating assembly.
