ABSTRACT:
The present invention is a lumbar support system that retreats into the seat back when reclined, providing a constant pressure support. The lumbar support system has a lumbar support basket that can retreat into the seat back. The lumbar support basket is supported by a crossbar that is pivotably connected to opposite sides of a seat frame via a pair of connecting members. A spring is provided for biasing the connecting members to a biased position.
