ABSTRACT:
A support apparatus for selectively supporting a human being in one of a plurality of positions includes a support structure and a seat assembly having a frame and a seat mounted on the frame for movement therewith. The seat assembly is positionable relative to support structure along an arcuate path defined by an arcuate guide track provided on one of the frame and support structure. A plurality of rollers are rotatably supported on the other of the frame and support structure, the rollers engaging the guide track to support the seat assembly on the support structure and being movable relative to the guide track to permit movement of the seat assembly relative to the support structure. A back support member may be pivotally mounted on the frame to permit selective positioning of the back support member in one of a plurality of positions relative to the seat while moving with the seat during movement of the seat assembly relative to the support structure.
