    • 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.

    • In a cushion support element for incorporation in a structure such as a seat, bed or the like comprising a platform formed by lateral side edge wires sheathed in a compressible material, and a plurality of transverse spring wires wound around the sheathing of the edge wires, an improved connection is provided between the transverse wires and the edge wires in that the transverse wires are wound around the sheathing, hooked over upon themselves to provide an interlocked connection and then bent back towards the sheathing so that their free ends engage the latter. This both shields the sharp ends of the transverse wires and also urges the sheathing into the crook of the wound transverse wire to ensure a tighter connection.
    • 在用于结合在诸如座椅,床等的结构中的缓冲支撑元件包括由围绕在可压缩材料中的横向侧边缘线形成的平台和缠绕在边缘线的护套周围的多个横向弹簧线, 在横向线和边缘线之间提供了改进的连接,因为横向线缠绕在护套上,钩在自身上以提供互锁连接,然后朝着护套弯曲,使得它们的自由端与其接合。 这两者都屏蔽了横向线的尖端,并且还将护套推入缠绕的横向线的弯头中以确保更紧密的连接。

    • 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).
