摘要：
A back portion for a chair includes a peripheral frame defining an opening therein. A lumbar support portion is disposed in the opening. The lumbar support portion comprises a substantially rigid panel. Two hinge devices are hingedly mounted on opposite sides of the peripheral frame. The lumbar support portion is mounted on the peripheral frame by the two hinge devices. Each hinge device has a biasing device associated with it to bias the hinge devices forwardly relative to the peripheral frame. A cushion may be mounted atop the lumbar support portion. The cushion has a first substantially planar sheet of resiliently flexible material and a second substantially planar sheet of resiliently flexible material. The first and second sheets are separated by a plurality of spaced webs of resiliently flexible material.
