Abstract
A lumbar support apparatus includes a guide rail on a seat frame, and a bendable occupant support structure mounted for sliding movement on the guide rail. The bendable structure, which is preferably configured as a grid, includes a spring that imparts increasingly bowed contours to the grid upon increasingly arched deflection of the spring relative to the seat frame and the guide rail. The apparatus further includes an actuator, a cable, and a fastener. A first section of the cable extends from the actuator into engagement with the grid so as to apply a bending force to the grid under the influence of the actuator. A second section of the cable extends from the first section to an end portion of the cable that is anchored to the seat frame.
