Abstract
An adjustable lumbar support device for installation within seats, and particularly vehicular seats, to enable a seat occupant to adjust a seat back to provide a desired amount of support for the lumbar region of the back. The adjustable lumbar seat support includes a pair of leaf spring members which are joined at their opposite edges with hinge members. Application of pressure to or release of pressure from the hinge members causes movement of the leaf members and a corresponding change in the central spacing between the leaf spring members such that the adjustable lumbar seat support is expanded or contracted. A flexion control device is provided to variably regulate the expansion and contraction of the hinge members such that the central spacing between the leaf spring members is changed and the adjustable lumbar seat support is expanded or contracted as desired. An actuator is also provided to enable the effortless operation of the flexion control device and use the adjustable lumbar seat support.
