A lumbar support device has a seat frame, a pair of brackets connected to the seat frame, a spring assembly connected to the pair of brackets in such a manner as to form a center section traversing the seat frame and a pair of cantilevered ends on opposite sides of the center section, and an actuator assembly operatively connecting the cantilevered ends. The pair of brackets respectively provide a pair of fulcrums about which the cantilevered ends can rotate. In operation, the actuator assembly moves the cantilevered ends of the spring assembly to bow the center portion. The lumbar support device may also have a single cantilevered end. |
