Abstract
A synchronizing mechanism for the correlated movement of the seat and backrest assembly of an office chair has a basic carrier capable of being positioned on the chair upright, a seat carrier and a backrest carrier. The backrest carrier is capable of pivoting about a transverse shaft and is connected directly in an articulated fashion both to the basic carrier and to the rear end area of the seat carrier such that a pivoting movement of the backrest in a rearward direction induces a lowering movement in the rearward area of the seat carrier. The seat carrier is connected in an articulated fashion to the basic carrier such that a horizontal sliding movement towards the rear is superimposed on the lowering movement of the seat carrier. Through the direct linking of the backrest carrier to the basic carrier and the seat carrier, it is possible to simplify the construction.
