    摘要： A seating unit includes a perimeter frame, a flexible seating surface supported by the frame, and parallel elongated resilient force-distributing members coupled to the seating surface to control a contour of the seating surface when supporting a seated user. The resilient force-distributing members 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 seated user. The resilient force-distributing members can be wire rods, long strips, or other resilient material with memory. The resilient force-distributing members 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, such as by providing on ends of the resilient force-distributing members one or more rotatable pivots, sliding support at ends of the resilient force-distributing members, stretchable rubber supports, and/or elastic fabric.

    摘要翻译： 座椅单元包括周边框架，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，其联接到座位表面，以在支撑就座的使用者时控制座位表面的轮廓。 弹性力分布构件沿其长度是可弯曲的并且在数量和分布上是足够的，以便基本上减小座面的局部偏转，从而减少由坐着的使用者感到的压力点接触。 弹性力分配构件可以是线材，长条或具有记忆的其它弹性材料。 弹性力分配构件可以以各种方式支撑在周边框架的相对侧上，以在弹性力分布构件弯曲期间减小相对侧上的向内压力，例如通过在弹性力分配构件的端部上设置 一个或多个可旋转的枢轴，在弹性力分配构件的端部处的滑动支撑件，可伸缩橡胶支撑件和/或弹性织物。

    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 back includes an integrated 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 that 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： A chair includes a perimeter frame with side, front and rear sections defining an open area. A support structure includes slats and/or resilient wires supported on the perimeter frame and bridging between the side sections. A cushion of non-uniform thickness has a relatively thinner rear portion supported on the support structure and a relatively thicker front portion supported on the front section adjacent its rearwardly-facing edge. The thin rear portion of the cushion combines with the support structure to provide a transition region over the inwardly-facing edge of the front section. By this arrangement, a seated user does not sense a sudden change in supportive force across the transition region.

    摘要： A back construction for a chair includes a back shell having a plurality of horizontal bands defining a flexible lumbar section, with the back shell including non-parallel guides defined along its edges. A vertically adjustable lumbar support includes a panel body located at the flexible lumbar section, a bent wire member that engages the panel body and that is stretchable laterally, and opposing handles attached to ends of the bent wire member that engage the non-parallel guides. The opposing handles slidingly follow the guides and are movable between a first position where the bent wire member is flexed to a first width dimension, and a second position where the bent wire member is flexed to a second width dimension different than the first width dimension. Slots in the panel body retain the bent wire member to the panel body, but permit the bent wire member to be stretched horizontally during vertical adjustment of the lumbar support. The panel body includes generously radiused upper and lower edges shaped to slide over top and bottom edges of the plurality of horizontal bands without catching on and unacceptably twisting individual ones of the bands when the vertically adjustable lumbar support is vertically adjusted.
