摘要： A clutch mechanism for seating units of the type having an adjustable support member. The clutch mechanism includes a housing having first and second opposite ends, and a generally cylindrical inner sidewall. A clamp member is movably interconnected with the housing, and the clamp member is adapted to secure the housing to a frame member of a seating unit. A rotor is rotatably mounted within the housing, and the rotor has a generally cylindrical outer surface. The rotor defines an axis of rotation, and has a channel with opposed sidewalls in the cylindrical outer surface extending generally parallel to the axis. A handle extends from the rotor, and a pulley is rotatably interconnected with the rotor. The pulley has an annular groove and an extension disposed in the channel of the rotor. The pulley is adapted to be operably coupled to an adjustable support member of a seating unit to provide adjustment of the support member. A coil spring is disposed around the rotor, and has opposite ends disposed in the channel adjacent the opposed sidewalls with the extension of the pulley position between the opposite ends. The coil spring frictionally engages the cylindrical inner sidewall and prevents rotation of the pulley relative to the housing when a rotational force is applied to the pulley. The sidewalls of the channel of the rotor engage the opposite ends of the coil spring and generate tension on the coil spring in a manner tending to reduce friction between the coil spring and the housing to permit rotation of the rotor and pulley relative to the housing when a force is applied to the handle.

摘要翻译： 一种用于具有可调节支撑构件的座椅单元的离合器机构。 离合器机构包括具有第一和第二相对端以及大致圆柱形的内侧壁的壳体。 夹紧构件与壳体可移动地互连，并且夹紧构件适于将壳体固定到座椅单元的框架构件。 转子可旋转地安装在壳体内，并且转子具有大致圆柱形的外表面。 转子限定旋转轴线，并且具有在圆柱形外表面中具有大致平行于轴线延伸的相对侧壁的通道。 手柄从转子延伸，并且滑轮与转子可旋转地互连。 滑轮具有设置在转子通道中的环形槽和延伸部。 滑轮适于可操作地联接到座位单元的可调节的支撑构件，以提供支撑构件的调节。 螺旋弹簧设置在转子周围，并且相对端设置在邻近相对侧壁的通道中，并且带轮位置在相对端之间延伸。 当旋转力施加到滑轮时，螺旋弹簧摩擦地接合圆柱形内侧壁并防止滑轮相对于壳体的旋转。 转子的通道的侧壁与螺旋弹簧的相对端接合，并且以一种倾向于减小螺旋弹簧和壳体之间的摩擦力的方式产生螺旋弹簧上的张力，以允许转子和滑轮相对于壳体旋转， 向手柄施加力。

摘要： A highly flexible and cost effective stranded conduit for a control cable assembly comprises about twenty-one (21) to thirty (30) individual strands of low carbon SAE 1005 to 1040 steel wire wrapped in a contiguous helical configuration about a plastic resin liner at a pitch of 0.5 to 3.0 inches, with the individual strands of wire having a diameter of 0.008 to 0.020 inches. The wire layer is surrounded by a jacket material formed of an abrasion resistant plastic resin.
