Abstract
One example of a vehicle seat assembly includes a seat back, a seat bottom coupled to the seat back, and a bladder support system coupled to at least one of the seat back and the seat bottom. The bladder support system includes air cells and a pump fluidly connected to the air cells to selectively inflate the air cells when the pump receives an activation signal. A valve system defining flow paths fluidly connected between the pump and the air cells. The valve system includes at least three control valves, with each control valve generating a control valve output when receiving the activation signal. The valve system also includes passive valves movable to an open position to inflate the corresponding air cell when receiving at least three control valve outputs. A controller is configured to send the activation signal to the control valves and the pump.
