Abstract
An inflatable lumbar support arrangement includes a pump unit for selectively inflating a bladder whereby the bladder is located in the lumbar region of the backrest. The pump unit is connected to the bladder and includes a pump and a release valve. The pump unit further includes a single actuator handle which projects sidewardly from below the seat and is movable vertically in opposite directions. The actuator handle operatively cooperates with both the pump and the release valve which are thereby operated by movement of the actuator handle in the opposite directions. As such, the pump is operated to inflate the bladder by repetitive movement of the actuator handle in one direction, while the release valve is opened by movement of the actuator handle in the opposite direction.
