Abstract
A wheelchair according to one embodiment is provided with a frame and a seat assembly that is movable in elevation relative to the frame. The frame has a seat hinge mounted thereto, and is rotatably coupled to left and right wheels. The seat assembly has a side member hingedly coupled to the seat hinge and a seat back hingedly coupled to the side member such that the seat back can be maintained at a constant angle relative to the frame when the side member pivots about the seat hinge and moves the seat assembly between multiple elevations. The wheelchair also comprises a lockable spring hingedly mounted to the frame and to the seat assembly; the spring is lockable at multiple positions thereby locking the seat assembly at the multiple elevations. This spring can be sufficiently elastic to suspend the seat assembly and absorb shock at each of the locked multiple elevations.
