Abstract: A chair comprises a seat; a support for the seat; and, a plurality of biasing members mounted between the support and the seat, the biasing members, in combination, have a compressive strength sufficiently high to essentially resist static movement of a person while seated in the chair and sufficiently low to cushion dynamic loads applied to the seat when a person sits down quickly in the chair. Alternately the chair comprises a plurality of connecting members extending between the seat and the support, each connecting member having at least one first detent member to lockingly connecting the seat to the support.

Abstract: A chair back is provided with an adjustable lumbar support member. The vertical height of the lumbar support member and/or the amount of lumbar support which is provided by the chair back may be adjusted. The controls for adjusting the lumbar support member are positionable on the sides and the rear surface of the chair back.

Abstract: A chair back comprises a rear surface, a front surface spaced from the rear surface and a side extending between the front and rear surfaces; a lumbar support member positioned between the front and rear surfaces and mounted for vertical movement with respect to the chair back and for forward movement with respect to the front surface; a first control member positioned on the rear surface of the chair back for adjusting the forward movement of the lumbar support member; and, a second control member positioned adjacent one of the sides of the chair back for adjusting the vertical height of the lumbar support member.

Abstract: A chair comprises a longitudinally extending seat; a support member for supporting the seat at an elevated height; a slide member fixedly mounted to one of the seat and the support member; a housing positioned between the seat and the support member and fixedly mounted to the other of the seat and the support member, the housing having a cavity for slidably receiving the slide member, the slide member mounted for longitudinal movement forward and rearward with respect to the housing; and, an adjustment member mounted in the housing and drivingly connected to the slide member, whereby movement of the adjustment member in a first direction causes the seat to move forwardly and movement of the adjustment member in the opposite direction causes the seat to move rearwardly.

Abstract: An office panelling system is advantageously combined with fiber optic communication cable wherein the panels of the system are generally open in the center thereof and the vertical space of the panel is advantageously used for reducing the curvature of the cable between panels disposed at an angle. The panels have a metal framework onto the sides of which cover members are secured such that the interior of the framework is generally open. The framework includes a host of distributed passage ports therethrough for allowing communication cables and the like to pass through the framework where desired.

Abstract: A modular office panelling system has been improved by providing an air circulation arrangement of selectively cool or remove heat from a particular area defined by the panelling system. Fans are provided in removable panel cover portions which can advantageously be secured in the office panelling system in the same manner as fabric covered removable cover portions. Thus, the air circulation arrangement may be provided as an original specification or added as a retrofit in the field. The interior of the panel is also used as a large inlet plenum whereby the flow of air into the panel is at a slow velocity.

Abstract: Securement and cooperation between panels of an office panelling system is improved by mechanically connecting panels in a manner to maintain a particular orientation and to allow transfer of loads therebetween. The mechanical fasteners are advantageously combined with compressible strips between panels which not only deform during fastening of the fasteners, but engage the panel and distribute the clamping force to a larger area thereby adding structural rigidity.
