摘要： An office-type chair (10) including a back support (12) having a suspension mesh (14) back support and a back support frame (16). The suspension mesh (14) back support has an integral retaining channel (48) disposed at a peripheral edge thereof, and the back support frame (16) includes a central pair of upright support posts (18) and wedge base (22) for mounting to a chair frame. The back support frame (16) includes a plurality of flexible and spaced support arms (20) extending laterally outward from the upright support posts (18). The support arms each have a peripheral edge configured for fastenerless attachment in a tensioned state within the suspension mesh (14) retaining channel (48). An upholstery cover (60) encapsulates the suspension mesh (14) and back support frame (16). The office chair (10) also includes a lumbar mechanism (80) including a resilient cushion (62) that may be positioned in the space between the suspension mesh (14) and the support frame (16) and adjusted along the vertical extent of the back support (12) by rolling the resilient cushion (62) on the rear of the suspension mesh (14).

摘要： An office chair includes a seat and a backrest that are pivotally connected together at a pivot axis such that the backrest can pivot with respect to the seat between an upright position and a reclining position. The seat is mounted on a base such that the seat can move with respect to a base, and the seat includes front and rear portions that can pivot with respect to one another. When the backrest is pivoted from the upright position to the reclining position, both of the seat and the pivot axis move forward with respect to said base, and the seat front portion flexes with respect to the seat rear portion such that the angle between said upward faces of said seat front portion and the seat rear portion increases. The backrest may also include an upper portion and a lower portion that can pivot with respect to one another. When the backrest is moved to the recline position, the angle between the forward faces of the upper and lower backrest portions decreases.

摘要： An improved chair back is formed of a molded construction uses multiple mold shots of mold materials to develop different performance characteristics in selected areas of the chair back. The chair back has the appearance of a unitary molded panel, but is formed from multiple mold shots which preferably are performed at multiple stations on a mold tool. By providing multiple mold shots and selected materials to form different areas of the chair back, different performance characteristics are generated including the provision of a peripheral frame providing structural rigidity to the chair back, a lumbar support panel which provides localized support to the lumbar region of the chair occupant, and a thin sheet-like support panel extending between the frame and enclosing the interior region defined between the peripheral frame to provide a more flexible and pliant surface providing more comfortable contact with the occupant's back.

摘要： An office chair is provided having a back assembly which is configured to provide supplemental support to the back of a chair occupant in addition to the support provided by the primary support surface of the chair back. The chair back includes a lumbar support unit having a lumbar support pad wherein asymmetric support is provided to the left and right halves of the lumbar pad. As such, the asymmetric support loads are independently adjustable to more comfortably support a chair occupant. The chair back also includes a pelvic support pad which is disposed vertically adjacent to the lumbar support.

摘要： A tilt control mechanism (18) for an office chair (10) includes a spring assembly (56) therein which controls the tilt tension on the back assembly (24). This tilt control mechanism (18) includes a tension adjustment assembly (50,57) having a cam wedge (82) which supports the legs (79) of a pair of coil springs (77) and a cooperating drive block (83) assembly which cooperates with the cam wedge to drive the cam wedge upwardly and downwardly to vary the tilt tension. The drive assembly includes drive blocks mounted on a threaded shaft which are displaceable sidewardly toward and away from each other to either drive the cam wedge upwardly when the drive blocks (83) move together or downwardly when the drive blocks move away from each other.

摘要： An arm assembly (21) on a chair (11) includes an armrest (22) which adjacent one end is connected to an upper end of a support column (23). The support column is axially slidably supported within an elongate support tube (61) which projects downwardly adjacent a side of the chair seat (14). The support column and support tube have a cooperating linear anti-friction bearing arrangement (71) therebetween, the latter incorporating a resilient support track (77) to eliminate circumferential clearance. A latch member (82) is carried on the column and cooperates with a plurality of latch-receiving slots (85) formed in the support tube. The latch member is activated by a push rod (91) which projects upwardly through the support column, and at its upper end is activated by a lever (93) which terminates in a button (96) adjacent the front of the armrest. The latch member (82) has an inclined cam surface (87) and the lower end of the push rod (91) has a cam roller (88) which on downward movement of the push rod effects sideways movement of the latch member and disengagement of the latch member from the slots (85).
摘要翻译： 在椅子（11）上的臂组件（21）包括扶手（22），其邻近一端连接到支撑柱（23）的上端。 支撑柱轴向可滑动地支撑在细长支撑管（61）内，该支撑管（61）向下邻近椅子座（14）的一侧向下突出。 支撑柱和支撑管在其间具有协作的线性抗摩擦轴承装置（71），后者包括弹性支撑轨道（77）以消除周向间隙。 闩锁构件（82）承载在柱上并与形成在支撑管中的多个闩锁接收槽（85）配合。 闩锁构件由推杆（91）启动，推杆（91）通过支撑柱向上突出，并且在其上端由靠近扶手前部的按钮（96）的杆（93）启动。 闩锁构件（82）具有倾斜的凸轮表面（87），并且推杆（91）的下端具有凸轮辊（88），所述凸轮辊在所述推杆向下运动时实现所述闩锁构件的侧向运动， 所述闩锁构件来自所述狭槽（85）。
