Lumbar Seat

The In-Line Circuit Breaker is hot at all times and applies voltage to the Sport Seat Switches. Each Sport Seat Switch contains a lumbar seat switch and a bolster seat switch.

The lumbar seat switch controls both power to the Sport Seat Pump motor and air flow to the Lumbar Bladder.

Moving the switch in one direction powers the Sport Seat Pump motor and, at the same time, routes compressed air to the Lumbar Bladder; the Lumbar Bladder inflates. Releasing the switch stops the Pump motor and closes the air passage to the Lumbar Bladder; the Bladder remains inflated.

Moving the switch in the other direction opens the air passage to the Bladder and the Bladder deflates; the Pump does not run.

The bolster seat switch controls both power to the Sport Seat Pump motor and air flow to the Bolster Bladder. Operation of the bolster mechanism is similar to that of the Lumbar mechanism.
