Patent ID: 7611202

Claim:
A tilt mechanism for use on a chair having a chassis, a seat, and a back, the mechanism comprising: a seat base adapted to be slidably coupled to the chassis and configured for rigid coupling with the chair seat; a back bracket configured for coupling with the chair back; a back support bar having a body portion configured to extend from the chassis and a distal end configured for moveable engagement with the back bracket; a guide track formed with at least one channel and being coupled with and extending rearwardly away from the seat base; and a back follower member configured for coupling with and depending downwardly from the chair back and received within the at least one channel of the guide track for moveable engagement therewith; wherein movement of the chair from an upright position to a recline position such that the chair back moves rearwardly and downwardly relative to the chassis and achieves an increasing angle of tilt relative to the chair seat results in the back bracket moving relative to and in engagement with the back support bar distal end, the back follower member moving within the at least one channel of the guide track and the seat base sliding forwardly relative to the chassis.
