Description
Die Erfindung betrifft eine Vorrichtung zur Sitzneigeverstellung eines Stuhles, insbesondere eines Bürostuhles.The The invention relates to a device for seat tilt adjustment of a Chair, in particular an office chair.
Hochwertigere Bürostühle sind oft mit einer sogenannten Synchronmechanik ausgerüstet, mit deren Hilfe sich Sitz und Rückenlehne des Stuhles beim Zurücklehnen des Benutzers in einer korrelierten Bewegung gemeinsam nach hinten unten verschwenken. Darüber hinaus sind zur Verbesserung der Ergonomie von Bürostühlen verschiedene Einstellmöglichkeiten bekannt, wie beispielsweise die Höheneinstellung von Sitz, Rücken- und Armlehne, die Verstellbarkeit der Armlehne in Längs- und Querposition sowie die Längsverstellung des Sitzes.Higher quality Office chairs are often equipped with a so-called synchronous mechanism, with their Help the seat and backrest of the chair when leaning back of the user in a correlated movement together backwards swivel down. About that In addition, to improve the ergonomics of office chairs different settings known, such as the height adjustment of the seat, back and Armrest, the adjustability of the armrest in longitudinal and transverse position as well the longitudinal adjustment of the seat.
Darüber hinaus wird zur weiteren Verbesserung der Ergonomie von Bürostühlen zunehmend eine Einstellbarkeit der Grundneigung des Sitzes gefordert. Dabei soll es zumindest möglich sein, den Sitz zwischen einer waagerechten Position und einer leicht nach vorn geneigten Position zu verstellen. Von dieser Position aus wird dann bei der Aktivierung der Synchronmechanik die damit hervorgerufene Schwenkbewegung des Sitzes nach hinten unten vollführt.Furthermore is increasingly becoming one to further improve the ergonomics of office chairs Adjustability of the basic inclination of the seat required. It should at least possible be the seat between a horizontal position and a light one to tilt forward inclined position. From this position then, when activating the synchronous mechanism, it turns off caused pivoting movement of the seat backwards down performs.
In
der Patent
Eine Aufgabe der Erfindung ist es, eine Sitzneigeverstellung bereitzustellen, die eine besonders sichere und zuverlässige Verstellung der Sitzneigung ermöglicht.A The object of the invention is to provide a seat tilt adjustment, which allows a particularly safe and reliable adjustment of the seat angle.
Diese Aufgabe wird durch eine Vorrichtung nach Anspruch 1 gelöst.These The object is achieved by a device according to claim 1.
Erfindungsgemäß umfaßt die Vorrichtung einen Basisträger, einen mit dem Basisträger über ein Gelenk verbundenen Sitzträger sowie einen Verstellmechanismus derart, daß eine Schwenkbewegung des Sitzträgers nach vorn über eine im wesentlichen waagerechte Grundposition hinaus wahlweise möglich ist.According to the invention, the device comprises a basic carrier, one with the base carrier over a joint connected seat support and an adjusting mechanism such that a pivoting movement of the seat carrier forward over a substantially horizontal basic position also optional possible is.
Eine Grundidee der Erfindung ist es, für die Verstellung der Sitzneigung des Stuhles den Sitzträger selbst über seine Grundposition hinaus zu verschwenken. Die Sitzneigeverstellung kann erfindungsgemäß wahlweise anbeziehungsweise abgeschaltet werden. Dies ermöglicht eine besonders flexible Handhabung, je nach Anwendungsfall und Benutzerwunsch. Darüber hinaus kann die erfindungsgemäße Vorrichtung optional in eine ansonsten übliche Synchronmechanik eingebaut werden. Ein Nachrüsten ist mit anderen Worten wahlweise möglich.A The basic idea of the invention is to adjust the seat inclination of the chair the seat carrier itself over to pivot out of its basic position. The seat tilt adjustment can according to the invention optionally be switched off or switched off. This allows a particularly flexible Handling, depending on the application and user request. Furthermore can the device of the invention optional in an otherwise usual Synchronous mechanism to be installed. A retrofit is in other words optionally possible.
