One embodiment of a lumbar support system includes one or more air cells adapted to be mounted to a vehicle seat assembly, a pump selectively inflating the air cells, and a valve (116) fluidly connected between the pump and the air cells. The valve includes a body defining a pair of cavities (178a, 178b) corresponding with each of the air cells. The valve further includes an inflate plunger (164a) movable in one of the cavities to selectively open the cavity and a deflate plunger (164b) movable in the other cavity to selectively open the other cavity. Furthermore, the valve includes an actuator (120) movably coupled to the body between a first operational position to inflate the air cell, and a second operational position to deflate the air cell. An electrical switch (is electrically coupled to an electrical input of the pump and closed when the actuator is moved to the first or second operational positions. |
