ABSTRACT:
A pneumatic sit/stand device which is preferably used in assisting an invalid or physically disadvantaged person in rising from, or being seated in, a chair. The sit/stand device includes an inflatable bag having two or more cavities which inflate sequentially to help stabilize the person as he is raised from or lowered into a chair. Rear and side wall cavities inflate first to provide stabilization and push the person forward so that his feet contact the floor. A center cavity then inflates to lift and thrust the person into a standing position. The side walls help prevent the person from tilting or leaning from one side to another as air pressure equalizes the bag. The device can be used alone by the physically disadvantaged person or in conjunction with an attendant whose duty is to assist the person in sitting or standing.
