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.
