Abstract

A reclining chair (20) is provided which includes a base frame (33), a support linkage assembly (30, 32) pivotally supported from the base frame (33), a seat back (26) operably coupled to the support linkage assembly (30, 32) and the reclining chair (20) including a seat frame (22). A longitudinal link (50) is operably interconnected to the support linkage assembly (30, 32). A recline linkage assembly (100) is operably coupled to the longitudinal link (50) and to the base frame (33) for controlling movement of the longitudinal link (50) from an upright position to at least one reclined position. A
rotatable drive shaft (80) is journally supported by the longitudinal link (50). The reclining chair (20) further includes a leg rest assembly (28) supported from the longitudinal link (50) and operably coupled to the drive shaft (80) for movement from a retracted position to an extended position in response to rotation of the drive shaft (80).
The support linkage assembly further operates to recline the chair (20) between an upright position and a fully reclined position. The reclining chair (20) optionally includes a swivel base assembly (420) which provides a rotational degree of freedom between the chair (20) and a floor base (456).
