A lumbar support device, preferably secured in a seat frame, includes a support structure attached between a pair of levers that are rotated by an actuator assembly. In one embodiment, the pair of levers are each formed from a serpentine wire, and each lever wraps around a bar that is secured to the seat frame and wraps around a side of the support structure. The actuator assembly rotates the pair of levers which move the support structure into the lumbar region and pull the support structure in tension. |
