Abstract

Bei einem Stuhl (1), insbesondere einen Bürostuhl, mit einer über einem Lehnenträger (3) an einem Sitzträger (2) neigbar gehaltenen Rückenlehne (4) und mit einer Sitzfläche (6), die sich über mindestens einen Sitzlenker (7,8) am Sitzträger (2) abstützt, ist zur Synchronisation zwischen der Bewegung der Rückenlehne (4) und der Bewegung der Sitzfläche (6) ein mit der Sitzfläche (6) und mit dem Lehnenlenker (3) drehbar verbundener Koppellenker (14) vorgesehen. Zur Absenkung der Sitzfläche (6) bei der Synchronbewegung ist der mit der Sitzfläche (6) über einen oberen Drehpunkt (D5) und mit dem Sitzträger (2) über einen unteren Drehpunkt (D4) drehbeweglich verbundene hintere Sitzlenker (8) nach vorne unten geneigt angeordnet, wobei der Abstand des oberen Drehpunktes (D5) zur Rückenlehne (4) kleiner ist als der Abstand des unteren Drehpunktes (D4).
