Abstract
A seat back comprises a frame structure from which are resiliently suspended a first platform element and a second platform element that together provide support for the upholstery of the seat. The first platform element can be buckled to provide adjustable horizontal lumbar support. In addition, the lower margin of the platform element is coupled to a cranked shaft that can be adjustably rotated to vary the vertical position of the platform element in the frame structure. During such adjustment, the upper margin of the platform element (3) slides upon lateral rails of the upper platform element (4).
