ABSTRACT:
A lumbar support apparatus includes a seat frame, a first wire support member fixed to the frame, a second wire support member attached to the frame and a third wire support member interconnecting the first and second support members. The second support member is movable to a position forward of the seat frame. The movement of the three support members by virtue of the interconnections causes a reduction in the discomfort to a seat occupant.
