摘要： An integrated chair and control arrangement for tilt back chairs. The chair has a base 4, as well as a back 5 and a bottom or seat 6 which are interconnected for mutual rotation about a common axis 7. The common axis 7 is located above the chair bottom 6, forward of the chair back 5, and generally adjacent to the hip joints H of a seated user. A control supports 3 the chair back 5 and chair bottom 6 on the base 4 in a mnner such that rearward tilting of the chair back 5 simultaneously shifts the chair back 5, the chair bottom 6, and the location of the common axis l0 in a manner which maintains the adjacent spatial relationship between the common axis 7 and the hip joints l3 of the seated user to provide improved comfort and support.
摘要翻译：用于倾斜后椅的综合椅子和控制装置。椅子具有基座4以及背部5和底部或座椅6，它们互相连接以相对于公共轴线7相互旋转。公共轴线7位于椅子底部6的上方，椅背5的前方，并且通常与坐着的使用者的髋关节H相邻。控制装置以椅子5的方式支撑椅背5和底座4上的椅子底部6，使得椅背5的向后倾斜同时将椅子背部5，椅子底部6和公共轴线10的位置移动到保持坐着的用户的公共轴线7和髋关节13之间的相邻空间关系，以提供改善的舒适度和支撑。

摘要： A chair column has a spindle (2) for securing at its upper end (3) to a chair seat, the lower portion (6) of the spindle threadedly carrying a first clutch dog in the form of a nut (7). A second clutch dog is provided by an indent (8) in a tubular casing (9), the lower end (22) of which is secured in use to a chair base. In order to adjust the height of the chair seat relative to the base, the unoccupied seat is turned, and the interengaged clutch dogs will effect an adjustment. When a person sits on the seat the spindle moves down to compress a spring (10), and the clutch dogs are automatically disengaged.
In order to prevent inadvertent adjustment of the nut (7) by swivelling of the occupied chair seat, the nut (7) is arranged to be locked to the spindle (2) by a locking member (12) which is conically shaped in its upper half to have a wedging engagement with the spindle (2) and nut (7). The lower half of locking member (12) is also of conical shape but with a larger cone angle to provide a self-centring bearing with a spring abutment member (11).
摘要翻译：椅子柱具有用于将其上端（3）固定到椅子座的心轴（2），心轴的下部（6）螺纹地携带螺母（7）形式的第一离合器爪。第二离合器爪由凹部（8）设置在管状壳体（9）中，其下端（22）固定在椅子基座上。为了调整椅座相对于基座的高度，转动空闲的座椅，并且相互啮合的离合器狗将进行调整。当一个人坐在座椅上时，主轴向下移动以压缩弹簧（10），并且离合器卡爪自动脱开。为了通过旋转被占用的座椅来防止螺母（7）的无意调节，螺母（7）被布置成通过锁定构件（12）锁定在主轴（2）上，锁定构件（12）在其上部一半与主轴（2）和螺母（7）具有楔形接合。锁定构件（12）的下半部也是圆锥形，但具有较大的锥角，以提供具有弹簧抵接构件（11）的自定心轴承。
