ABSTRACT:
A hollow beam is supported in cantilever fashion at one end on a frame and has laterally spaced rail flanges along its lower edges. A carriage has rollers on each corner which are supported on the rail flanges. A cable drum extends longitudinally of the carriage and is rotatable relative to the carriage. A shaft having a square cross section extends through the drum and the carriage and is rotatably supported at its ends by the beam. Rollers at each end of the drum and transverse to the shaft roll along the sides of the shaft. A motor mounted on the frame is connected to rotate the shaft and the drum thereon. A cable wound on the drum is connected to the center of a rigid hanger. Flexible suspension cables of equal length hang from the ends of the hanger and connect to the corners of a rectangular seat frame. A flexible side, back, neck and head panel has side edges anchored along the suspension cables connected to the front corners of the seat frame, and has tubular guides anchoring the rear edges of the side panel in isosceles relation to the cables at the front corners of the seat. Side strips from the neck and head supporting portions of the panel lap the rear cables and are anchored along their front edges to the front cables.
