    摘要: A reclining chair is provided which includes a base, and a support linkage assembly pivotally supported from the base. 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.

    摘要: A chair including a power-assisted linear actuation drive mechanism having a cam guide which is linearly movable upon rotation of a shaft for selectively actuating a lift and tilt linkage mechanism, and for causing forward lifting and tilting movement of the chair when a motor of the mechanism is operated in a first direction. Rotation of a shaft in a second opposite direction acts to lower the chair to a normal seating position. Continued rotation in the second direction causes a first cam block pivotably mounted to the cam guide to engage a first follower assembly for causing extension of a leg rest assembly and for causing a rearward tilt of the chair frame. Further rotation in the second direction causes a second cam block pivotably mounted to the cam guide to engage a second follower assembly for causing reclining movement of the chair and for causing an additional rearward tilt of the chair frame. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.
