摘要： A low profile knee-tilt chair control for controlling biased tilting between a chair seat plate and a chair base plate of a pedestal base chair wherein the chair base plate is supported by a single vertical spindle at the rear of the base plate, and the chair seat plate pivots about a horizontal axis at the front of the base plate. The chair seat is biased to an at-rest position by a low profile, conical helical compression spring operable between the base plate and chair seat and located between the spindle and the horizontal pivot axis of the base plate. The low profile, conical helical compression spring is so mounted relative to the base plate and chair seat plate that the small coils of the compression spring may pass through the large coils during compression of the spring. The control is further characterized by a lockout for securing the chair seat plate against tilting relative to the base plate in either of two different, selectable, at-rest positions.
摘要翻译：一种低调的膝盖倾斜椅控制装置，用于控制椅座座板与座椅之间椅座椅座基板之间的倾斜倾斜，其中椅基座由基板后部的单个垂直轴支撑，椅子座板围绕基板前部的水平轴线枢转。椅座通过可在基板和椅座之间操作并且位于主轴与基板的水平枢转轴线之间的低轮廓的锥形螺旋压缩弹簧而偏置到静止位置。小型锥形螺旋压缩弹簧相对于基板和椅座座安装，使得压缩弹簧的小线圈在弹簧压缩期间可以穿过大线圈。该控制的特征还在于，该锁定装置用于在两个不同的，可选择的静止位置中的任何一个中固定椅座板以防止相对于基板倾斜。

摘要： A J-back calibration device is adapted to vary respective positions of the seat and the back on a chair to which it is removedly attached. A chair measurement device is mounted to the seat of the chair and is adapted to take measurements of the chair given a set position of the J-back calibration device. A design of experiments software is provided with test condition information including the variable positions of the J-back calibration device and measurements from the chair measurement device. The software generates a table of configuration settings for the J-back calibration device at which shirt-pull and bridging or other such variable sought to be optimized can be measured and provided to the software. Through graphical and other analytical tools, optimal configuration settings for the variable positions of the J-back calibration device are determined. The J-back of a chair is adapted to these calibrated settings.

摘要： A chair control mechanism is provided for use on a chair having a separate seat 14 and backrest 16 that move with respect to a base 12 of the chair. The mechanism 22 includes a housing 26 supported on the base, and brackets 28, 30 secured to the seat and backrest. The seat bracket 28 is supported on the housing for pivotal movement about a horizontally extending front pivot axis 68 between an upright position and a reclining position, and the front pivot axis is located adjacent the front end of the housing. The backrest bracket 30 is supported on the housing for pivotal movement about a horizontally extending rear pivot axis 80 that is located rearward of the front pivot axis. A mechanical linkage 70, 78 is connected between the brackets at a position spaced rearward of the rear pivot axis relative to the housing for transmitting pivoting movement between the brackets, and a spring assembly 32 is connected between the housing and the backrest bracket for biasing the seat and backrest toward the upright position.

摘要： A retaining plate is provided for use in the assembly of a chair to couple a J-back to a tilt mechanism. The J-back is provided with a number of mounting holes. Similarly, the tilt mechanism is provided with a number mounting holes that can be aligned with the mounting holes in the J-back. The retaining plate has a number of mounting holes disposed therethrough that are located to align with the mounting holes of the J-back and the tilt mechanism. The plate also includes a nut-retaining wall that is formed around the mounting holes and that is dimensioned to hold a threaded nut. The plate has a mechanism that is used to couple the plate to the tilt mechanism. In use, nuts may be placed within and held by the nut-retaining wall, and the plate may be coupled to the tilt mechanism so that the J-back may be coupled to the tilt mechanism by threading bolts into the nuts, the nuts being held in place by the nut-retaining walls.

A forward travel-stop control assembly 38 is provided on the mechanism for adjusting the forward most position of the seat and backrest, as is a tilt control assembly 36 which permits the seat and backrest to be locked against tilting movement. The tilt control assembly 36 includes a locking plate 102 supported on the housing for relative translational movement between an extended position in which the locking plate is received in an aperture of the backrest bracket to lock the backrest bracket from further pivotal movement, and a retracted position removed from the aperture to allow further pivotal movement of the seat and backrest. A locking pawl 106 is supported on a lever 104 of the tilt assembly and engages the lock plate 102 to retract and extend the plate when the lever is rotated. In addition, a clutch is interposed between the actuating lever and the locking pawl for exerting a rotating force on the locking pawl to move the locking pawl from the second position when the actuating lever is rotated. The rotating force of the clutch is smaller than the friction force that is exerted on the locking plate when the pivoting force of the spring assembly 32 is exerted on the locking plate such that the locking plate can only be retracted when the friction force is reduced to a magnitude less than the rotating force.

摘要： In a chair having a base, a seat, a backrest, and a tilt control mechanism, a horizontal adjustment mechanism is provided for allowing fore and aft shifting movement of the seat relative to the backrest. The tilt control mechanism typically includes a pair of rails or other mounting structure by which the control mechanism is normally fastened to the seat. The rails present a pair of laterally spaced longitudinally extending edges and a plurality of mounting holes arranged in a predetermined pattern. The horizontal adjustment mechanism includes a seat mounting assembly provided with a pair of laterally spaced guides adapted to engage the edges of the rails to support the seat mounting assembly for sliding movement on the control mechanism. The seat mounting assembly presents at least one plurality of mounting holes by which it can be fastened to the seat, and these mounting holes of the seat mounting assembly are arranged in the same pattern as the holes in the rails so that the horizontal adjustment mechanism can be employed on the chair without requiring modification or added expense. Likewise, by employing the rails of the tilt control mechanism to support the guides of the seat mounting assembly, a low profile is presented that reduces the overall height of the seat above the ground.
摘要翻译：在具有基座，座椅，靠背和倾斜控制机构的椅子中，设置有水平调节机构，用于允许座椅相对于靠背的前后移动运动。倾斜控制机构通常包括一对轨道或其他安装结构，通过该一对轨道或控制机构通常将其固定到座椅。轨道呈现一对横向间隔的纵向延伸的边缘和以预定图案布置的多个安装孔。水平调节机构包括座椅安装组件，该座椅安装组件设置有一对横向间隔开的导轨，其适于接合轨道的边缘以支撑座椅安装组件，用于在控制机构上滑动。座椅安装组件具有至少多个安装孔，通过该安装孔可将其固定到座椅上，并且座椅安装组件的这些安装孔以与轨道中的孔相同的图案布置，使得水平调节机构可被雇用在椅子上，不需要修改或增加费用。类似地，通过使用倾斜控制机构的轨道来支撑座椅安装组件的引导件，呈现出降低座椅在地面上方的整体高度的低轮廓。
