摘要：
A pneumatically cushioned vehicle seat and apparatus and method to adjust the same is provided by the present invention. A novel switching and pumping arrangement for the pneumatic seat and/or seating combination allows the pump to inflate the pneumatic cushion and also deflate the pneumatic cushion. Use of the pump for deflation of the pneumatic cushion eliminates the need of the chair occupant pushing against the same cushion when adjusting the seat to a less firm position.
