Abstract

Die Erfindung betrifft eine Synchronmechanik für eine korrelierte Sitz-Rückenlehnen-Bewegung eines Bürostuhles, mit einem auf einer Stuhlsäule plazierbaren Basisträger (1), einem Sitzträger (3) und einem Rückenlehnenträger (4). Um eine Synchronmechanik bereitzustellen, durch die ein hoher Sitzkomfort auf preiswerte Art und Weise erreicht werden kann, wird eine Mechanik vorgeschlagen, bei welcher der Rückenlehnenträger (4) um eine Querachse (8) schwenkbar mit dem Basisträger (3) verbunden ist und einen in Wirkverbindung mit dem Sitzträger (3) stehenden Mitnehmer (9) aufweist derart, daß der Sitzträger (3) bei einer Schwenkbewegung (6) der Rückenlehne nach hinten ebenfalls eine Bewegung (13) nach hinten vollführt.

The invention relates to a synchronous mechanism for a correlated seat-backrest movement of an office chair, with a base support (1) placeable on a chair column, a seat support (3) and a backrest support (4). In order to provide a synchronous mechanism by which a high seating comfort can be achieved in a cost effective manner, a mechanism is proposed in which the backrest support (4) about a transverse axis (8) pivotally connected to the base support (3) and one in operative connection with the seat support (3) standing driver (9) has such that the seat support (3) during a pivoting movement (6) of the backrest to the rear also performs a movement (13) to the rear.
