摘要： A chair is provided with a frame defining a curved arm support, a seat supported in the frame, and a back. An arm member is movably mounted on the arm support and operatively connected to the back so that movement of the back between upright and reclined positions is controlled by the arm member and arm support. A resilient spring is operatively connected to the back to bias the back towards an upright position. In one embodiment, the resilient spring encompasses the curved arm support and provides support for a seated user's arm. In another embodiment, an arm cap covers the resilient spring. Optionally, the arm cap slideably rides on roller bearings over the curved arm support. In another embodiment, the curved arm support and arm member are telescopingly arranged, and the resilient spring is operably placed therein. Another embodiment includes first and second springs, the second springs being disengageable to produce discrete selectable levels of bias force for biasing the back toward the upright position. In another embodiment, the resilient spring is continuously adjustable, and includes a control mechanism including opposing springs that slide on a pivotable actuator arms thus creating a variable torque arm which is adjustable to vary the resulting bias force on the chair back.

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.

摘要： A utility distribution system is provided for open office plans and other similar settings, and includes a prefabricated floor construction designed to be supported directly on a building floor. The floor construction has a hollow interior which defines at least one raceway to route utility conduits therethrough, and a floor surface on which workstations can be positioned. The utility distribution system also includes at least one utility post having a foot which mounts to the floor construction to support the utility post in a generally upstanding orientation. The foot portion of the utility post has an open area disposed above and communicating with the floor raceway. At least one utility outlet is mounted on the utility post, and is adapted to dispense a selected utility therefrom. The utility post has at least one utility channel in which utility conduits can be routed, and includes an outwardly oriented open face. The utility channel extends continuously between and communicates with the utility outlet and the open area of the foot, such that utilities can be readily provided to the workstations by pulling selected utility conduits from the floor raceway, through the open area of the foot portion of an adjacent utility post, and then laying the selected utility conduits into the utility channel portion of the utility post by insertion into the open face thereof to a location adjacent the utility outlet for connection therewith.

摘要： A chair control includes a flexible truss having tandem springs interconnected in spaced relation so that they interact to provide a unique torque versus displacement profile during flexing, with a portion of one of the springs moving longitudinally relative to a portion of the other spring as they are flexed. A stop on the springs limits the longitudinal movement, thereby limiting the angle of tilt both in the upright and rearward chair back positions. In one form, the springs are pairs of leaf springs connected in tandem and operably attached to a chair back and bottom formed by a corrugated member. In another form, one of the springs is a flexible shell forming a chair with the other spring attached thereto in a nested arrangement. In yet another form, the flexible truss is a separate module installable in furniture as a self-contained energy absorber.
