ABSTRACT:
A mobility chair is provided with a pair of mounting members projecting downwardly from armrests on opposite lateral sides of a seat frame approximately midway between a front end of the seat frame and a back frame. The mounting members are pivotally connected to supports extending upwardly from a chassis so that the user-receiving frame moves between forwardly inclined and rearwardly inclined positions. A gas cylinder extends between the chassis and the frame and prevents the angular movement of the frame from accelerating. The pivotal connections between the mounting members and the support members are disposed below the seat. In a restraining chair, the mounting members are disposed on opposite lateral sides of the seat substantially closer to the front end of the seat than to the back, and the pivotal connections between the mounting members and the support members are adjacent to the seat. The gas cylinder extends between the support members and the back of the frame and is adapted to urge the restraining chair towards the forwardly inclined position.
