    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 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： 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： A seating unit includes a base, a reclineable back, a seat, and a control operably supporting the back and the seat on the base for synchronous movement between upright and recline positions. The control includes a pair of flexible support members and a link that combine to operably support the seat and back for synchronous movement on the base upon recline, which provides ergonomic non-shearing support for a seated user during recline. The back and seat each include perimeter frames, parallel resilient support members extending between side frame sections of the perimeter frames, and covers covering the resilient support members for distributed support and aesthetics. By this arrangement, the flexible member and the link move the one component along a defined path during recline of the back, and the seat and back also provide ergonomic support, both during recline and without recline.

    摘要： A seating unit includes a seat, a back, a base, and a motion control having a plurality of flexible supports for operably supporting the seat and back on the base. The flexible supports are movable in a generally fore-to-aft direction but stiff in a generally vertical direction, and further the flexible supports have end sections projecting generally outward from said base for operably engaging the seat and/or back, so that when the flexible supports flex in the fore-to-aft direction, they provide for directed movement of the seat and/or the back. In one form, the flexible supports are integrally molded with the center section of the motion control.
