<p>An assembly for incorporation in a seat back to provide adjustable lumbar support comprises a platform element (3) suspended by tension springs (2) in a seat frame (1) to support the cushioning of a back rest. The platform element (3) has elongate lateral rails (5,9) between which extend transverse wires (10) that provide the platform support. A Bowden cable (21) is linked between respective portions of each of the rails (5,9) to apply a force of longitudinal compression, whereby the rails (5,9) are caused to be hinged outwardly at an articulation point (150) to vary the lumbar support provided by the transverse wires (10). <IMAGE> <IMAGE></p> |
