Abstract

Bei einem Stuhl mit einem Tragrahmen (1), einer Sitzplatte (6) und einer verschwenkbaren Rückenlehne (5) weist eine Lagereinrichtung (11) für die Sitzplatte (6) mindestens ein Biegefederglied (12) auf, das im Bereich seines der Rückenlehne zugewandten Endes einseitig am Tragrahmen (1) gehalten ist und auf dessen Oberseite (14) im Bereich seines federelastisch auslenkbaren, freien Endes (13) ein an der Sitzplatte (6) angebrachtes Lagerteil (16) aufliegt, wobei der vorderseitige Teil der Sitzplatte (6) vom Biegefederglied (12) getragen wird. Zur Ausbildung eines Gegenlagers ist eine am Tragrahmen (1) angeordnete Führungsfläche (17) vorgesehen, an der das Lagerteil (16) oder ein weiteres an der Sitzplatte (6) angebrachtes Lagerteil anliegt, wobei die zur Vorderseite des Stuhls hin nach unten abfallende Oberseite (14) des Biegefedergliedes (12) und die Führüngsfläche (17) winkelig zueinander stehen und in Richtung zur Rückseite des Stuhls aufeinander zulaufen und im unverschwenkten Zustand der Rückenlehne (5) das Biegefederglied (12) gegenüber dem Lagerteil (16) vorgespannt ist.
