Abstract

Es wird eine bewegungsgekoppelte Servoeinrichtung (29) für ein Sitzteil (14), insbesondere eines Stuhls (1) vorgesehen, Das Sitzteil ist synchron zu einem ausgehend von einer Ruheposition in mehrere Neigungspositionen neigbaren Rückenlehnenteil (15) an einem Traggestell (5) längsverschieblich und gegebenenfalls bezüglich des Traggestells (5) zwangsgeführt neigbar. Die Servoeinrichtung (29) ist einerseits mit dem Traggestell (5) und andererseits mit dem Sitzteil (14) verbunden. Die Servoeinrichtung (29) ist als eine mehrere Gelenkhebelelemente (31, 38; 31', 38') umfassende, scherenförmige Gelenkhebelanordnung (30, 30') mit progressiver Federkraftbeaufschlagung derart ausgelegt, dass in jeder Position des Sitzteils (14) durch die relativen Winkeländerungen der Gelenkhebelelemente (31, 38; 31', 38') zueinander eine etwa konstante Kraftübertragung auf das Sitzteil (14) erfolgt. Ferner ist die Auslegung derart getroffen, dass sich bei einem relativ großen Längsverschiebungsweg des Sitzteils (14) ein kurzer Federweg bei der Federkraftbeaufschlagung ergibt.
