    摘要: A seating unit is provided having a base assembly, a back frame pivoted to the base assembly for movement between upright and reclined positions, and a seat slidably supported on the base assembly and pivoted to the back frame so that the seat moves forwardly and its rear moves forwardly and downwardly with the back frame upon recline. A flexible back is connected to the back frame at top and bottom locations and is provided with lumbar adjustment for improved lumbar force/support and shape. A seat is provided with seat depth adjustment and with active and passive thigh flex support. The seat includes a front section adjustably and/or flexibly supported on a rear section for optimal comfort while supporting a seated adult user's thighs, With the rear section being configured to carry a majority of the weight of a typical seated adult user. A novel energy mechanism is provided that includes a moment arm shift adjuster for adjusting the spring tension on the back frame. The moment arm shift adjuster is readily adjustable and includes an overtorque device to prevent damage to components of the energy mechanism.

    摘要: A chair base includes a leg assembly having a plurality of radially-extending legs, and a leg cover adapted to cover the legs. The tubular legs have a top surface divided by a center line and have apertures offset from the center line. The leg covers are adapted to cover the legs, and the leg covers including downwardly extending off-centered bosses for engaging the apertures. Each of the tubular legs have an end with aligned vertical holes therein. A sleeve-like pintle retainer is located in the aligned vertical holes and flared at its top and bottom to hold the pintle retainer in the tubular legs. The leg assembly includes a tubular center hub. The plurality of radially extending tubular legs each have a top wall, a bottom wall and opposing side walls, the top and bottom walls each having an arcuately shaped end engaging the center hub. A pair of ring welds extend continuously circumferentially around the center hub for welding the arcuately shaped ends of the top and bottom walls to the center hub. In a modified form the covers include a plurality of flat-topped intermediate retainers shaped for attachment to a top of the legs, and a plurality of aesthetic flat-bottomed trim pieces shaped for mating adhering attachment to the top of the retainers.

    摘要: A chair, with independent control of a lumbar portion of a seat back and a thoracic portion of the seat back, has a seat connected with a base and a control connected with the base, generally under the seat. A first support, pivotally connected with the control, extends from the control to the thoracic portion of the seat back. A second support extends to the lumbar portion of the seat back. The two supports operate independently and the thoracic and lumbar portions of the seat back rotate independently rearward with respect to the seat, providing sympathetic back support for a user. The thoracic portion may rotate laterally to follow twisting movements of a user's thoracic region. The lumbar portion may be connected with the second support to limit lateral rotation of the lumbar portion.
