Abstract
A reclining chair is provided which includes a base frame, a support linkage assembly pivotally supported from the base frame, a seat back operably coupled to the support linkage and a chair frame, including a seat frame, secured to the support linkage. A longitudinal link is operably interconnected to the support linkage assembly. A recline linkage assembly is operably coupled to the longitudinal link and to the base for controlling movement of the longitudinal link from an upright position to at least one reclined position. A rotatable drive shaft is journally supported by the longitudinal link. The reclining chair further includes a leg rest assembly supported from the longitudinal link and operably coupled to the drive shaft for movement from a retracted position to an extended position in response to rotation of the drive shaft. The support linkage further operates to recline the seat assembly between an upright position and a fully reclined position. The reclining chair optionally incudes a swivel base which provides a rotational degree of freedom between the chair frame and the floor.
