Abstract
Description
Die Erfindung bezieht sich auf das Gebiet der Möbelindustrie. Sie betrifft einen Stuhl mit verstellbarer Sitztiefe.The invention relates to the field of furniture industry. It concerns one Chair with adjustable seat depth.
Es sind unterschiedliche technische Lösungen für Stühle bekannt, mit denen zur Anpassung an die jeweilige Beinlänge eines Benutzers die Sitztiefe des Stuhles verstellt werden kann.There are different technical solutions for chairs known, with which Adaptation to the respective leg length of a user's seat depth of the chair can be adjusted.
So wird beispielsweise beim Modell Chicago der Anmelderin der gesamte Sitz auf einer Schiene nach vorn (bzw. hinten) verschoben. Der Nachteil dieses Systems besteht darin, dass die gesamte Sitzmulde, die vordere Überwölbung für die Abstützung der Oberschenkel sowie die Abstützung für den Beckenkamm nach vorn wandert und dadurch die Entfernung zum Lehnenabstützpunkt größer wird. Dadurch ist kein optimales Sitzen mehr möglich.For example, in the Chicago model of the Applicant, the entire seat becomes a rail forward (or rear) moved. The disadvantage of this system is that the entire seat recess, the front overhang for the Support of the thighs and the support for the iliac crest after moves forward and thereby the distance to Lehnenabstützpunkt is greater. As a result, optimal sitting is no longer possible.
Bekannt ist auch ein Stuhl der Fa. Sitag mit zweigeteiltem Sitz, bei welchem ein Teil des Sitzes unter das andere Teil abtaucht und dadurch eine Sitztiefenverstellung erfolgt. Diese technische Lösung hat den Nachteil, dass das Polster im vorderen Bereich getrennt ist und somit keine durchgängige Fläche vorhanden ist. Das führt beim Benutzer zu einem unangenehmen Sitzgefühl. Außerdem können auch Druckstellen beim Besitzen auftreten.Also known is a chair of the Fa. Sitag with two-part seat, in which a Part of the seat dips under the other part and thereby one Seat depth adjustment takes place. This technical solution has the disadvantage that the Pad is separated in the front area and thus no continuous area is available. This leads to an unpleasant sitting feeling for the user. In addition, pressure points can also occur when owning.
Schließlich ist aus der Zeitschrift Office Design vom 03.06.2000, S. 65 ein Bürostuhl mit einem Schiebesitz bekannt, bei welchem die Polsterplatte des Stuhles über einen Keil für die Beckenrandstützung gezogen wird. Die Beckenrandabstützung soll bei Veränderung der Sitztiefe immer in fester Position zum Rücken bleiben. Zwar wird durch eine neuartige Polstertechnik, bei der der Polsterschaum im Randbereich und im Bereich der Sitzbeine härter ausgebildet ist als in dem Bereich, in dem die Oberschenkel aufliegen, ein hoher Sitzkomfort erreicht, welcher aber aufgrund einer fehlenden Sitzmulde nachteilig wieder reduziert wird.Finally, from the magazine Office Design of 03.06.2000, p. 65 a Office chair with a sliding seat known in which the upholstery of the Chair is pulled over a wedge for the pelvic edge support. The Beckenrandabstützung should always change the seat depth in a fixed position stay to the back. Although it is by a novel upholstery technology, in which the Upholstery foam in the edge region and formed harder in the area of the seat legs is as in the area where the thighs rest, a high level of comfort reached, but which due to a lack of seating disadvantageous again is reduced.
Aus US 6 193 313 B1 ist ein Stuhl mit verstellbarer Sitztiefe bekannt, welcher eine nicht verformbare Sitzpolsterplatte und eine Sitztragplatte aufweist. Die untere Tragplatte weist eine Gleitebene auf, die in Form von geraden Schienen ausgebildet ist, auf denen Räder, die an der Sitzpolsterplatte angebracht sind, vorwärts und rückwärts bewegbar sind, so dass auf diese Weise eine Sitztiefenverstellung realisiert werden kann.From US 6 193 313 B1 a chair with adjustable seat depth is known which a non-deformable seat cushion plate and a seat support plate. The lower support plate has a sliding plane, which is in the form of straight rails, on which wheels, which are attached to the seat cushion plate, forward and backward are movable, so realized in this way a seat depth adjustment can be.
Die Erfindung versucht, diesen genannten Nachteil des bekannten Standes der Technik zu vermeiden. Ihr liegt die Aufgabe zugrunde, einen Stuhl mit verstellbarer Sitztiefe zu schaffen, bei welchem die Sitztiefe problemlos an die verschiedenen Beinlängen unterschiedlicher Benutzer anpassbar ist und die Sitzmulde des Stuhles immer an der gleichen Stelle verbleibt, so dass ein extrem hoher Sitzkomfort realisiert wird.The invention seeks to overcome this mentioned disadvantage of the prior art Technology to avoid.
