  • Seat arrangements providing adjustable lumbar support

    Abstract: An assembly for incorporation in a seat back to provide adjustable lumbar support comprises a platform element suspended by tension springs in a seat frame to support the cushioning of a back rest. The platform element has elongate lateral rails between which extend transverse wires that provide the platform support. A Bowden cable is linked between respective portions of each of the rails to apply a force of longitudinal compression, whereby the rails are caused to be hinged outwardly at an articulation point to vary the lumbar support provided by the transverse wires.
