Abstract

Ein Bürostuhl enthält eine Sitzfläche (1) und eine Rückenlehne (2), deren Neigung durch ein Führungsgetriebe in Form eines Koppelgetriebes gesteuert ist. Dessen Bewegungsebene verläuft parallel zur Zeichnungsebene. Das Koppelgetriebe enthält in Form einer Getriebekette aneinandergelenkt einen Sitzträger (7) als Basislenker (3), einen darüber verlaufenden Sitzlenker (4) als Träger der Sitzfläche (1) und als Verbindungsglied zwischen beiden einen die Rückenlehne tragenden Rücklenker (6). Diese Getriebekette wird durch eine Rückstellfeder entgegen der Rückneigerichtung nach oben (14) beaufschlagt. Die Rückstellfeder ist eine Drehfeder (10) mit die Gelenkachse (15) zwischen Sitzträger (7) und Rücklenker (9) umgebendem oder bildendem Federkörper (11). Die Drehfeder (10) ist mit einem vorderen Federende (13) am Sitzträger (7) abgestützt. Sie bildet mit ihrem rückwärtigen Federende (9) mindestens teilweise den Rücklenker (6). Der Rücklenker (6) ist dadurch in Rückstellrichtung (14) selbsttätig vorgespannt.
