| Abstract: |
A wheelchair provides a seat mounted to a base preferably through use of a universal joint to provide for selective orientation of the seat. A pair of actuators are interposed between the seat and base so that selective extension and retraction of the actuators orients the seat as desired. A level sensing device(s) provides suitable output signals to control the extension and retraction of the actuators, and thus the final orientation of the seat. This allows a wheelchair occupant to remain level while the chair traverses uneven ground or to selectively reposition the seat to relieve pressure points without the assistance of an attendant.

Having thus described the invention, it is now claimed:
1. A self positioning wheelchair seat comprising:
- a base;
- wheels rotatably secured to the base;
- a seat adapted to receive an occupant therein; and
- a mounting assembly for securing the seat to the base including
- (i) a joint interposed between the seat and base allowing at least two degrees of movement of the seat relative to the base,
- (ii) an actuator assembly extending between the seat and base, the actuator assembly being secured to the seat to permit the seat to pivot fore and aft, and side to side and;
- (iii) a sensing device that indicates whether the seat is level relative to the ground surface and provides a signal to the actuator assembly for adjusting the position of the seat in response thereto.
