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