摘要： A chair includes a base, a seat, a back, and a control operably supporting the seat and back on the base for movement between upright and recline positions. The seat and back include a stiff perimeter frame with opposing perimeter sections, and a plurality of rods each independently bendable in vertical and angled directions. End bearings on the rods are captured in pockets in the perimeter frame, which limits their inward and outward sliding movement. The control includes front and rear leaf springs and a pivot arm operably supporting the seat and the back for synchronous movement, with the direction of movement being such that energy is stored during recline. The energy stored during recline assists in providing a heavier person with added counterbalancing force during recline. A booster mechanism is also selectively engageable for added support upon recline.
摘要翻译：椅子包括基座，座椅，靠背以及可操作地支撑座椅并且在基座上用于在直立和倾斜位置之间移动的控制器。座椅和靠背包括具有相对的周边部分的刚性周边框架和多个杆，每个杆可沿垂直方向和成角度的方向独立地弯曲。棒上的端部轴承被捕获在周边框架的口袋中，这限制了它们向内和向外的滑动运动。该控制装置包括前后板簧和一个可操作地支撑座椅和后部以进行同步运动的枢转臂，其运动方向使得在倾斜过程中存储能量。斜倚期间储存的能量有助于在斜倚期间提供更重的平衡力。助力机构也可选择性地接合以在斜躺时增加支撑。

摘要： A seating construction includes a perimeter frame defining an open area, and a one-piece molded seating component supported on the frame. The seating component includes a plurality of integrally-formed flexible slats defining a support surface over the open area. Resilient wires are coupled to the slats to resiliently support the slats when flexed. The component can be handled as a unit for assembly, and is retained by connecting rods that extend along the side section of the frame, with the slats each rotatably engaging mating bearing structure on the frame. A flex-limiting member in a center of the frame limits the resilient supports to a maximum deflected condition. Tabs on the molded component interconnect the slats and permit one-piece molding, but are either flexible or breakable to permit independent flexing of the slats. Methods related to the above are also disclosed.

摘要： A seating unit (50) includes a perimeter frame (90), a flexible seating surface supported by the frame, and parallel elongated resilient force-distributing members (103) coupled to the seating surface to control a contour of the seating surface when supporting a user. The resilient force-distributing members (103) are bendable along their length and are sufficient in number and distribution to substantially reduce localized deflection of the seating surface and thereby reduce pressure point contact felt by the user. The resilient force-distributing members (103) can be wire rods, long strips, or other resilient material with memory. The resilient force-distributing members (103) can be supported on opposing sides of the perimeter frame in various ways to reduce inward pressure on the opposing sides during flexure of the resilient force-distributing members (103).
摘要翻译：座椅单元（50）包括周边框架（90），由框架支撑的柔性就座表面，以及平行细长的弹性力分布构件（103），其联接到座位表面，以在支撑座椅表面时控制座位表面的轮廓用户。弹性力分配构件（103）沿着它们的长度是可弯曲的并且在数量和分布上是足够的，以基本上减小座面的局部偏转，从而减少使用者感觉到的压力点接触。弹性力分配构件（103）可以是线材，长条或具有存储器的其它弹性材料。弹性力分配构件（103）可以以各种方式支撑在周边框架的相对侧上，以在弹性力分配构件（103）弯曲期间减小相对侧上的向内压力。

摘要： A back includes an articulating back frame and a back support. The back frame has a lower segment pivoted to a chair control, an upper segment for thoracic support, and links forming a four-bar linkage with the upper and lower segments, with a joint being formed at the lumbar region. The back support is stretchable in limited directions to accommodate shape change in the articulating back frame but to provide adequate support to a seated user. Upon receiving a rearward pressure on the lumbar joint, the back frame itself changes shape. The pivot locations in the four bar linkage create a mechanism the simultaneously controls rotational and translational movement of the upper segment during flexure of the lumbar. The back frame is close to the back support to provide significant design flexibility, but permit substantial lumbar flexure. Various back supports are contemplated that accommodate articulation of the back frame.
摘要翻译：背部包括铰接式背部框架和背部支撑。靠背框架具有枢转到椅子控制件的下部段，用于胸部支撑的上部段，以及与上部和下部段形成四连杆机构的连杆，其中在腰部区域形成接头。靠背支撑在有限的方向上可伸缩，以适应铰接背部框架的形状变化，但为坐着的使用者提供足够的支撑。在腰部接受一个向后的压力时，靠背框架本身会改变形状。四连杆机构中的枢轴位置产生一种机构，该机构在腰部弯曲期间同时控制上部节段的旋转和平移运动。背框靠近背部支撑，以提供显着的设计灵活性，但允许大量的腰部弯曲。考虑了适应背部框架铰接的各种背部支撑。
