Abstract
A device for assisting physically handicapped persons in moving from a seated position or a standing position to a bathing position in a bathtub and then returning to a seated or standing position. This device consists of an inflatable seat of resilient material, a source of pressurized air, and pneumatically controlled valves for the controlled inflation and deflation of the seat. The seat has several sturdy walls of stiff resilient material which enhance structural stability of the seat while the seat is fully or partially inflated. The sturdy walls are connected by flexible collapse joints of flexible resilient material which allow predictable and compact folding of the sturdy walls as the seat is deflated. A flexible top and flexible side walls of flexible resilient material permit and conform to the folding of the sturdy walls in deflation. The seat is secured in place in the end of the tub opposite the water source by suction cups on the bottom and rear wall of the seat. The handicapped person is seated on the top of the seat while it is fully inflated and then the seat is deflated by actuating a deflation valve, lowering the handicapped person to the bathing position. When bathing is completed, the seat is inflated, raising the handicapped person to a seated position.
