APPARATUS AND METHOD FOR LUMBAR SUPPORT STRUCTURE

摘要

The invention is a lumbar support structure adapted to attach to a frame of a seat. An upper support bar (10) and a lower support bar (14) attach to the frame of the seat. A plurality of vertical springwires (30) connect to the support bars. Spacers (40) are used to maintain a desired distance between each of the springwires. A lumbar portion (36) of the springwires extends away from a plane containing the support bars. By utilizing different diameter springwires and different shaped limbar portions a saddle support distribution (50) is created. The saddle support distribution allows the structure to customize the response to an occupant sitting in the seat.
