ABSTRACT:
An adjustable lumbar support (100) adapted to be easily integrated into new or existing seat structures. Adjustable lumbar support (100) includes a lower floating plate (115) that is adapted to have a second, or upper, plate (130) hinged relative to the lower plate (115). The upper and lower plates have independently actuated support linkages (120and140) that are selectively actuated by first and second actuating mechanisms. In this manner, selective actuation actuator mechanisms associated with the lower and upper support plates (115and130) provides adjustment of a vertical dimension of the adjustable floating plate lumbar support. The degree of support provided by floating plates (115and130) is adjusted by adjusting the effective length of the support linkages.
