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.

A seat-mounted part (14), in particular a chair (1), is provided in a motion-coupled manner. The seat part is longitudinally displaceable on a support frame (5) and optionally in synchronism with a backrest part (15) which can be tilted from a rest position into a plurality of inclination positions with respect to the support frame (5) forcibly tilted. The servo device (29) is connected on the one hand to the support frame (5) and on the other hand to the seat part (14). The servo device (29) is designed as a multi-lever elements (31, 38, 31 ', 38') comprising scissor-type articulated lever assemblies (30, 30 ') with progressive spring force loading such that in each position of the seat member (14) by the relative angular changes the articulated lever elements (31, 38; 31 ', 38') to each other an approximately constant power transmission to the seat part (14). Furthermore, the design is such that results in a relatively long Längsverschiebungsweg of the seat part (14) a short spring travel in the Federkraftbeaufschlagung.
