Abstract
A control mechanism for a tilt back chair includes a control body supported in a relatively stationary position by an integral vertical post member. A torsion unit is freely mounted between two flanges of the control body rearwardly of the post member and includes two spring-urged components respectively joined to a rearwardly extending tilt bracket and a forwardly extending tension lever. The tension lever includes a medial opening freely surrounding the post member and adjustment means acting upon its forward edge to vary the angular relationship between the tension lever and control body and thus the torque being applied to the tilt bracket.
