ABSTRACT:
A seat cushion and body support assembly is provided where the cushion comprises a plurality of individually inflatable chambers. Each of the chambers is connected, through its own conduit means, to a controllable pressure source so that, when desired, the chambers can be inflated. The chambers may all be inflated simultaneously, and thereafter the operator can control individual vent or dump valves to reduce the pressure or volume of pressure fluid in any respective chamber, thereby achieving a desired contour for the cushion for purposes of body or back support; or the chambers may be individually inflated by operation of a respective valve for each chamber. The inflatable seat cushion and body support is portable, and is particularly intended for use in vehicles such as automobiles and trucks.
