ABSTRACT:
An adjustable recliner chair of the type in which the chair back is pivoted at an intermediate point to a supporting frame and the chair seat is pivotally supported at its rear by the chair back so that as the chair back is tilted rearwardly, the chair seat moves forwardly, the chair seat having adjacent its front an inclined cam surface which slidably engages a support member secured to said supporting frame so that as the chair seat moves forwardly the front of it moves upwardly. The support member and inclined cam surface are held together by an adjustable friction connection which is adjusted to vary the frictional effect tending to hold the chair seat in any adjusted position. The supporting frame may be mounted on a base through coil springs which enable the chair to be rocked. The adjustable friction connection, in such case, is adjusted to ensure that the frictional effect is sufficient to maintain the chair seat and chair back in their adjusted position as the coil springs are flexed during the rocking operation. The chair may also have a swivel connection between the supporting frame and base to enable the chair to be swivelled.
