摘要： An armrest includes an armrest support and a subassembly supported thereon for vertical adjustment by a height adjustment device having a rotatable high-lead-angle threaded shaft, a mating nut, and a trigger. The shaft member is rotatable upon a vertical force being placed on the subassembly, and the trigger engages the shaft to prevent rotation and fix a selected height position. The subassembly includes a housing, an armrest cap, and a pair of swing arms pivoted to each of the housing and cap for adjustably supporting the armrest cap for rotational and translational horizontal movement. Horizontal adjustment is controlled by choice of materials, a frictional wave spring and dampener. Optionally, the armrest cap includes a keyhole slot and one of the links includes a configured protrusion shaped to selectively linearly slide along a long part of the slot or rotate in the circular end of the keyhole slot.

摘要： A chair includes a lower back frame, a back construction, including a back support attached to the lower back frame, a cushion assembly attached to the back support, and a vertically adjustable lumbar. The lumbar frame includes a transition shell and a vertically sliding lumbar device having a plurality of horizontal flexible wires. A lower edge of the transition shell is positioned on top of an uppermost horizontal flexible wire of the lumbar device. The lumbar device is operably slidably mounted between the outer shell and cushion assembly and the transition shell upper edge slides between the outer shell and the upholstery cushion assembly. Another chair includes a Y-shaped lower back frame having two uprights and a cross-piece attached to the back support. An overlap flange and channel-shaped flange mate to form an overlap joint, including a box beam for added structural support.
摘要翻译：椅子包括下背框架，后结构，其包括附接到下后框架的后支撑件，附接到后支撑件的缓冲组件和可垂直调节的腰部。腰椎骨架包括过渡壳和具有多个水平柔性线的垂直滑动腰部装置。过渡壳的下边缘位于腰部装置的最上方的水平柔性线的顶部。腰部装置可操作地可滑动地安装在外壳和衬垫组件之间，并且过渡壳上边缘在外壳和内饰垫组件之间滑动。另一个椅子包括具有两个立柱的Y形下背框架和连接到后支撑件的横梁。重叠法兰和通道形凸缘配合以形成重叠接头，包括用于增加结构支撑的箱梁。

摘要： A vertically adjustable armrest includes a tubular support constructed for attachment to a chair, an armrest assembly telescopingly positioned in the tubular support, and a height adjustment mechanism slidably received in the armrest assembly. The armrest assembly includes a sleeve and a post. The height adjustment mechanism includes an actuator rod, an operative member, a locking member, and a resilient member. The actuator rod operatively engages the locking member with the inclined wedge mateably engaged with the inclined surface and the angled surfaces slideably engaged with the lateral followers. To vertically adjust the armrest, the operative member is lifted upward, causing the resilient member to compress and the teeth of the locking member to disengage from the detents. To reengage the teeth with the positional detents, the operative member is released.
摘要翻译：可垂直调节的扶手包括构造用于附接到椅子的管状支撑件，可伸缩地定位在管状支撑件中的扶手组件以及可滑动地容纳在扶手组件中的高度调节机构。扶手组件包括套筒和支柱。高度调节机构包括致动器杆，操作构件，锁定构件和弹性构件。致动器杆可操作地接合锁定构件，倾斜的楔形物可与倾斜表面配合接合，并且成角度的表面可与侧向从动件可滑动地接合。为了垂直调节扶手，操作构件被向上提升，导致弹性构件压缩，并且锁定构件的齿与制动爪脱离。为了用位置制动器重新啮合齿，操作构件被释放。
