Abstract
A lumbar system for use in a seat includes a frame having a first side and a second side substantially opposite the first side, a pump mounted to the second side of the frame and operable to pressurize air, and a control module mounted to the second side of the frame. The control module is in communication with the pump to receive pressurized air. The lumbar system also includes a plurality of air cells mounted to the first side of the frame. Each of the plurality of air cells individually communicates with the control module to receive variable amounts of pressurized air provided by the pump such that each air cell is independently inflatable. The frame, the pump, the control module, and the plurality of air cells are installable in the seat as a single unit by coupling the frame to the seat.
