Abstract

A synchronizing mechanism provides a correlated seat-backrest movement of an office chair. To provide a self-adjusting synchronizing mechanism which is structurally simple, a backrest support is flexibly connected directly both to a base support so as to be pivotable about a transverse axis and to a seat support such that a pivoting movement of a backrest from an initial position into a rearwardly pivoted position induces an immediate lowering movement of the rear region of the seat support, when viewed in the longitudinal direction of the chair, rearwardly downward. The seat support is flexibly connected to the base support by a coupling element which is hinged to the seat support and to the base support such that when the backrest performs the pivoting movement from the initial position into the rearwardly pivoted position, an immediate lifting movement of the front region of the seat support, is effected rearwardly upward.
