ABSTRACT:
An improved actuation mechanism is disclosed which is particularly well-suited for incorporation into "high-leg" reclining chairs. The actuation includes a swing linkage for coordinating the extensible movement of a leg rest assembly in response to reclining movement of a seat assembly with respect to the chair frame. An over-center biasing mechanism is provided for assisting in extending and retracting the leg rest assembly. Furthermore, the actuation mechanism also includes a tilt linkage for permitting the seat assembly to be independently tilted following extension of the leg rest assembly. The actuation mechanism also includes a mechanical stop arrangement is provided for positively defining the limits of retracted and extended movement of the leg rest assembly which, in conjunction with the over-center biasing mechanism, effectively inhibits undesirable droop of the leg rest assembly.
