Abstract
A multipurpose adjustment mechanism for a synchrotilt chair mechanism and a chair with the mechanism. The synchrotilt chair mechanism is for use on a chair that has a base assembly with an extending pedestal, a seat, and a back. The synchrotilt mechanism includes a chassis that is coupled to the pedestal and a seat plate that is coupled to the chassis and to the chair seat. The seat plate slides relative to the chassis. The synchrotilt mechanism further includes a multipurpose adjustment mechanism that can adjust both the height of the chair as well as the orientation of the seat with respect to the chassis. The multipurpose adjustment mechanism may also lock the seat plate with respect to the chassis, such that the seat will not move when the user reclines the chair.
