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。

摘要： A modular "bridge" section is disclosed having a seat frame assembly and a detachable seat back assembly supported therefrom. The seat frame assembly and the detachable seat back assembly are upholstered to define an aesthetically pleasing seat section which can be installed between two seat sections or, alternatively, which can be used as an armless end unit of a modular sectional arrangement. The detachable seat back assembly is further defined by an improved linkage mechanism for use with a retractable or "flip-down" sofa table comprising a pair of pivotable links, a centerboard mounted on one set of the links, and an upholstered cover which covers and aesthetically conceals the linkage mechanism and centerboard from view. Counter-balance means are provided to assist movement of the table between open and closed position.

摘要： A tray table assembly for a chair is disclosed which is adapted for use in a health care environment. The tray table assembly enables a seated occupant or care giver to quickly and conveniently pivot the tray table in various incremental positions throughout a generally horizontal 360.degree. circular path. The tray table assembly includes a main tray assembly pivotally coupled to a mounting arm assembly to facilitate the lateral adjustments of the tray table. Furthermore, the tray table assembly includes a locking mechanism for quickly and conveniently mounting and demounting the tray table assembly from the health care chair. Still further, the tray table assembly includes positioning means for retaining the tray table in the desired position.

摘要： A modular reclining chair having an improved chair frame assembly and improved pantograph linkage is disclosed. The chair frame assembly includes a hybrid front frame member assembly having a plywood front frame board and a pair of metal front frame brackets for interconnecting a pair of side frame assemblies to define a rigid box-like chair frame. The front frame member assembly is further interconnected with the actuation mechanism to provide an integrated chair frame assembly. The improved pantograph linkage is adapted to be readily removable from a fully assembled chair for facilitating field serviceability and repair without requiring partial or complete disassembly of the reclining chair.
