Abstract: An improved tilt rate control mechanism for a tilt back chair has an adjustable torsion spring, a tilt rate adjustment actuator and an actuator movement mechanism. The torsion spring has an adjustment lever for adjusting the tension on the torsion spring. The tilt rate adjustment actuator is disposed in contact with the adjustment lever such that the movement of the adjustment actuator causes movement of the adjustment lever. The adjustment actuator is moveable between (i) a first actuator position wherein the actuator is proximal to the torsion spring and the adjustment lever is in a minimum tension position, and (ii) a second actuator position wherein the actuator is distal from the torsion spring and the adjustment lever is in a maximum tension position.

Abstract: A chair having a seat and a back rest. The back rest is attached to the seat via a back rest support element. The flat spring can be made from a non-metallic material, such as from fiberglass. The back rest support element comprises a flat spring disposed under pretension. In one embodiment, the seat is disposed upon a seat support structure having four legs. Preferably, the legs are splayed outside the perimeter of the seat, so that the chair is stackable with chairs of like design. The seat and the back rest can be made from a lightweight plastic material, and that the support structure can be made from tubular steel.

Abstract: An improved, multifunction office furniture system having a novel interlocking connecting mechanism which permits the easy assembly of a variety of different structural components in a variety of different configurations to form highly efficient work areas. The system includes uniquely configured, vertical support columns to which a number of different types of structural components can be quickly and easily connected and provides a highly versatile work station system which is very attractive, is easy to assembly, disassemble and adjust, and yet, is structurally sound and durable in use. Because of its novel construction, the system is capable of readily accommodating changing work conditions in the users' facilities.
