摘要： A tilt control mechanism for an office chair includes a spring assembly therein which controls the tilt tension on the back assembly. The tilt control mechanism includes a control plate mounted to the control shaft on which the uprights are mounted, wherein the control plate rotates in combination with the uprights. This control plate is located within the control body and cooperates with a front stop assembly and a back stop assembly to vary the limits of forward and rearward tilting of the seat and back assemblies. Also, the tilt control mechanism includes a pneumatic actuator assembly having fixed and rotatable cam blocks. The rotatable cam block rotates relative to the fixed block such that the rotatable cam block is driven downwardly to depress the control valve of the pneumatic cylinder and thereby vary the height of the seat assembly.

摘要： A tilt control mechanism for an office chair includes a spring arrangement which permits forward and rearward tilting of the chair while also urging the chair to a normal upright position. The spring arrangement includes front and rear springs which act in combination such that the upward acting forces acting on the chair can be varied during use. The forces being applied by the front spring are adjusted by a side-actuated tension adjustment mechanism which incorporates a wedge block for adjusting the spring forces. Further, the rear springs provide a variable spring force such that the spring force is maximized when in the normal position but is decreased substantially once the chair is fully reclined. This reduction in spring force allows a user to maintain the chair in the fully reclined position with significantly less force than was required to tilt the chair rearwardly while a sufficient spring force continues to be applied by the front spring to urge the chair to the normal position.

摘要： An office-type chair is provided with a base, a seat-back arrangement including a seat assembly which is vertically tiltable relative to the base and a back assembly which is vertically tiltable relative to both the seat assembly and base, and a tilt control mechanism operatively coupled between the base and the seat-back arrangement for permitting the back assembly and seat assembly to be respectively rearwardly and downwardly tilted away from an upright position in a synchronous but differential rate. A front tilt control device is associated with and interconnected with the tilt control mechanism for permitting the seat and back assemblies to be synchronously and nondifferentially tilted forwardly away from the upright position.

摘要： An office-type chair which provides for synchronous differential tilting of the seat and back assemblies, with the seat assembly being constructed such that the front lip thereof does not significantly lift upon rearward tilting. The chair incorporates a tilt control mechanism formed by a control body which secures to the upper end of the chair pedestal and an upright which pivotally connects to the control body about an axis disposed forwardly of the pedestal. A pivot assembly connects the upright and control body together.

摘要： A height adjusting mechanism is connected between a rigid upright extending upwardly from the seat assembly and an inner shell of the back assembly. The height adjusting mechanism includes a ratcheting latch which engages a vertically elongate rack to maintain the back assembly at a selected elevation and a release lever or cam which is connected to the catch and automatically disengages the catch from the rack at the upper limit of travel of the back assembly. The release cam continuously contacts the inner shell of the back assembly and is deactivated merely by a short upward shifting of the back assembly which thereby permits the pawl to reengage the rack at any desired elevation. Accordingly, reengagement of the pawl with the rack can be accomplished at any point between the upper and lower limits of travel of the back assembly.
摘要翻译：高度调节机构连接在从座椅组件向上延伸的刚性立柱和后组件的内壳之间。高度调节机构包括棘轮闩锁，其接合垂直细长的齿条以将后组件保持在选定的高度;以及释放杆或凸轮，该释放杆或凸轮连接到所述卡扣并且在所述卡盘的行进上限处自动地从所述齿条脱离后组装。释放凸轮连续地接触后组件的内壳，并且仅通过后组件的短暂的向上移动来停用，从而允许棘爪以任何期望的高度重新接合齿条。因此，可以在背部组件的行进的上限和下限之间的任何点处实现具有齿条的棘爪的重新接合。
