    摘要： A chair includes a lower back frame, a back construction, including a back support attached to the lower back frame, a cushion assembly attached to the back support, and a vertically adjustable lumbar frame positioned between the back support and the cushion assembly. The lumbar frame includes a transition shell and a vertically sliding lumbar device having a plurality of horizontal flexible wires. A lower edge of the transition shell is positioned on top of an uppermost horizontal flexible wire of the lumbar device. The lumbar device is operably slidably mounted between the outer shell and cushion assembly and the transition shell upper edge slides between the outer shell and the upholstery cushion assembly. Also disclosed is a chair including a Y-shaped lower back frame having two uprights and a cross-piece attached to the back support. The uprights and cross-piece of the lower back frame include an overlap flange and the back support includes a channel-shaped flange having detents. The overlap flange and channel-shaped flange mate to form an overlap joint, including a box beam for added structural support.

    摘要： A cushion subassembly includes a support, a cushion of non-woven polymeric (PET) or PETE fibers with a formed edge that wraps over an edge of the support, and an upholstery sock pulled onto and covering the support and the cushion. The formed edge has sufficient structure to retain the cushion in place on the support as the upholstery sock is pulled onto the support. A back support shell supports the cushion assembly, and has first fasteners that engage in a first direction and second fasteners that prevent disengagement. The cushion assembly is stressed during assembly, especially at corners, but is thermally stress-relieved after assembly to relax the polymeric fibers and the upholstery sock to a state of minimized balanced tension. The back support shell includes a shallow depression on its face. The cushion fills the depression sufficient to eliminate loose fabric but provides a same force deflection curve across its shape.

    摘要： A chair includes a lower back frame, a back construction, including a back support attached to the lower back frame, a cushion assembly attached to the back support and a clip wedgingly engaged between the back support and the cushion assembly. The cushion assembly further includes an inner shell which includes two or more apertures and a hook extending downwardly and outwardly from each aperture. The clip further includes at least one angled ramp and at least one stop. The angled ramp is configured to allow the hook of the inner shell to slide through the angled ramp and the stop is configured to suspend sliding of the hook. Methods of assembling a back construction are also provided.

    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 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 seating unit illustrated as a mobile office chair includes a base, a back upright operably supported on the base for reclining movement and a back construction. The back construction includes a cushion assembly attached to a back support shell with quick-attach top and bottom connectors. Specifically, the back support shell includes top apertures, and the cushion assembly includes hooks for drop-in attachment to the top apertures. The back support shell also includes a molded bottom section defining a recess, and the back cover includes a stiffened edge flange configured to frictionally engage the recess to retain the back cover to the back support. The cushion assembly includes a cover assembly with an upholstered front panel, and a rear panel formed by a first sheet section having a one-directional stretch in a vertical direction, and a second section having a high-stretch property.
