A tilt control mechanism for a chair utilizing a control housing and a pivot block mounted for pivotal movement with respect to each other about an axis. An actuator block is supported for movement along that axis and carries a pin thereon. In one position of the actuator block, the pin engages a flange on the control housing, preventing pivotal movement of the control housing with respect to the pivot block. In another position of the actuator block along the axis, pivoting movement is permitted. In a third position of the actuator block along the axis, a gas cylinder mechanism is actuated controlling the height of the chair. |
