摘要： A seating unit includes a base, a seat, a back, and a control operably supporting the seat and the back on the base for movement between upright and recline positions. The control includes a spring providing a biasing supporting force to the back during recline, and further includes a booster mechanism for increasing the supporting force, and still further includes a stop member and a selector device for activating and deactivating the booster mechanism. The selector device is easily movable with a low effort that is independent from friction generated by internal components of the booster mechanism. The stop member is linearly slidably mounted atop a control housing for selectively engaging the booster mechanism and the link for movement between a disengaged position, a booster-engaged position, a partial-recline position, and a recline-prevented position.

摘要： A seating unit includes a base with a control housing, a back supported on the base for reclining movement, and a seat supported at least partially by a pivoting link on the base for synchronous movement with the back upon recline of the back. A back stop is operably mounted on a pair of parallel guide rods that extend transversely across the control housing for selective movement to a plurality of different positions where the back stop engages the link to limit movement of the seat and hence limit recline of the back to a plurality of selectable recline positions corresponding to the plurality of different positions.

摘要： A seating unit includes a back support with a perimeter frame defining an opening, and a plurality of resilient members spanning the opening. An upholstery cover extends over and covers the resilient members and a front of the perimeter frame. A bow-tie-shaped lumbar device is positioned between the cover and sides of the perimeter frame for vertical adjustment. The lumbar device includes a body with end sections defining a greater dimension than a middle of the body. Upper and lower edges of the end sections are thin and serve to wedgingly slip between the cover and the resilient members in a manner leading the middle over irregular surfaces between the resilient members. A thick area between the upper and lower edges causes a change in lumbar support force and shape as the lumbar device is adjusted. Handles are attached to the body by stretchable fabric.

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.

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.
摘要翻译： 背部包括集成的铰接背框和背部支撑。 后框架具有枢转到椅子控制器的下部段，用于胸部支撑的上部段，以及与上部和下部段形成四杆连杆的连杆，在腰部区域形成有关节。 背部支撑件在有限的方向上是可拉伸的，以适应关节式后框架中的形状变化，但为座椅使用者提供足够的支撑。 在腰部接头处收到向后的压力时，后框架本身变形。 在四杆连杆中的枢转位置产生一种机构，其同时控制腰部弯曲期间上段的旋转和平移运动。 后框架靠近后支撑，以提供显着的设计灵活性，但允许大量的腰部弯曲。 预期可以适应后框架的铰接的各种后支撑。

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.
