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.
摘要翻译：一种椅子，其包括具有凸轮引导件的动力辅助线性致动驱动机构，所述凸轮导向件在轴的旋转时可直线移动，用于选择性地致动提升和倾斜连杆机构，并且用于当椅子的电动机机构在第一方向上操作。在第二相反方向上的轴的旋转用于将椅子降低到正常的就座位置。在第二方向上的继续旋转使得可枢转地安装到凸轮引导件的第一凸轮块接合第一从动件组件，以使腿部组件延伸并引起椅子框架的向后倾斜。在第二方向的进一步旋转使得可枢转地安装到凸轮引导件的第二凸轮块接合第二从动组件，用于引起椅子的斜倚运动并引起椅子框架的额外的向后倾斜。支腿组件和倾斜联动装置的这种顺序操作是独立的，并且可以容易地禁止以选择性地消除任何一个特征。
