Abstract
A synchronizing mechanism for correlated seat/backrest motion of an office chair is provided with a base carrier to be placed on a chair column; a seat carrier, which is pivotable about a transverse axis and, at its front end, articulated to the base carrier; and a backrest carrier, which is also pivotable about a transverse axis and articulated to the base carrier. It is coupled with the seat carrier such that a backward pivoting motion of the backrest induces a lowering motion of the rear end of the seat carrier. The joint between the base carrier and the seat carrier is a turning and sliding joint so that the lowering motion of the seat carrier is combined with a horizontal sliding motion.
