Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: 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.
Abstract translation: 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。
