Description

Die Erfindung betrifft ein Sitzmöbel, insbesondere einen Bürostuhl, mit einem auf einem Sitzträger befestigten Sitz und einer an einem Rückenlehnenträger befestigten Rückenlehne, wobei der Rückenlehnenträger gelenkig an einem Basisträger angeordnet ist und der Rückenlehnenträger und der Sitzträger über zwei Hebel gelenkig miteinander verbunden sind.The invention relates to a chair, in particular an office chair, with a seat mounted on a seat support and a seat back attached to a backrest support, wherein the backrest support is pivotally mounted on a base support and the backrest support and the seat support are pivotally connected to each other via two levers.

Ein solches Sitzmöbel ist aus dem deutschen Gebrauchsmuster DE 20 2005 010 952 U1 bereits bekannt. Es zeichnet sich durch die Möglichkeit einer synchronen Verstellung von Rückenlehne und Sitz aus, bei der sich keine Relativbewegung zwischen Rückenlehne und Kleidung einer sitzenden Person ergibt. Außerdem bleibt der untere Teil des Rückens der Person in allen Neigungsstellungen der Rückenlehne gut unterstützt.Such seating is from the German utility model DE 20 2005 010 952 U1 already known. It is characterized by the possibility of a synchronous adjustment of the backrest and seat, in which there is no relative movement between the backrest and clothing of a seated person. In addition, the lower part of the person's back remains well supported in all recline positions of the backrest.

Bei dem bekannten Sitzmöbel ist jedoch ein dritter Hebel vorgesehen, der drehgelenkig am Basisträger gelagert ist und den hinteren der beiden Hebel, die den Sitzträger und den Rückenlehnenträger miteinander verbinden, zwangsführt. Die bekannte Konstruktion der Synchronmechanik zwischen Rückenlehne und Sitz ist durch den benötigten dritten Hebel relativ aufwändig.In the known seating, however, a third lever is provided, which is pivotally mounted on the base support and the rear of the two levers, which connect the seat support and the backrest support together, forcibly leads. The well-known construction of Synchronous mechanism between the backrest and seat is relatively complicated by the required third lever.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, die bekannte Synchronmechanik konstruktiv zu vereinfachen und dabei ihre günstigen Eigenschaften beizubehalten.The present invention is therefore based on the object to simplify the known synchronous mechanism constructive while maintaining their favorable properties.

Die Aufgabe wird durch ein Sitzmöbel der eingangs genannten Art gelöst, das erfindungsgemäß dadurch gekennzeichnet ist, dass einer der beiden Hebel unmittelbar am Basisträger zwangsgeführt ist.The object is achieved by a chair of the type mentioned above, which is inventively characterized in that one of the two levers is forcibly guided directly on the base support.

Beim erfindungsgemäßen Sitzmöbel kann also auf einen dritten Hebel verzichtet werden. Zweckmäßigerweise kann außerdem der vordere der beiden Hebel, der sowieso dichter am Basisträger angeordnet ist, an diesem zwangsgeführt sein. Hierdurch ergeben sich auch günstigere Kräfteverhältnisse für die Zwangsführung.When seating furniture according to the invention can therefore be dispensed with a third lever. Conveniently, in addition, the front of the two levers, which is anyway arranged closer to the base support, be forcibly guided on this. This also results in more favorable balance of power for the forced operation.

Bei einer bevorzugten Ausführungsform kann der Hebel über eine Verzahnung am Basisträger zwangsgeführt sein. Die Verzahnungen von Hebel und Basisträger können dabei auf Kreisbogenabschnitten liegen, sodass der Hebel wie das Zahnrad eines Planetengetriebes auf dem Basisträger abrollen kann, wenn die Neigung des Sitzes und der Rückenlehne verstellt wird. Diese Art der Zwangsführung ist sehr robust und verzichtet auf bewegliche Teile zwischen Hebel und Basisträger.In a preferred embodiment, the lever may be forcibly guided via a toothing on the base support. The teeth of lever and base support can lie on circular arc sections, so that the lever as the gear of a planetary gear can roll on the base support when the inclination of the seat and the backrest is adjusted. This type of forced operation is very robust and dispenses with moving parts between lever and base support.

Die Anlenkpunkte der Hebel am Rückenlehnenträger und am Sitzträger können unabhängig von der Schwenkstellung der Hebel alle unterhalb der hinteren Hälfte des Sitzes angeordnet sein. Auf diese Weise lässt sich eine ergonomische Synchronverstellung von Sitz und Rückenlehne erreichen.The articulation points of the levers on the backrest support and on the seat support can be arranged independently of the pivotal position of the lever all below the rear half of the seat. In this way, an ergonomic synchronous adjustment of the seat and backrest can be achieved.

Zweckmäßigerweise kann außerdem einer der Hebel, vorzugsweise der zwangsgeführte Hebel, über ein Federelement in einer seiner Endlagen der Schwenkbewegung vorgespannt sein. Dabei wird man diejenige Endlage auswählen, in der die Rückenlehne senkrecht gestellt ist. Die Vorspannung durch das Federelement sorgt dafür, dass der Stuhl in eine definierte Lage zurück bewegt wird, wenn er nicht belastet ist.Conveniently, in addition, one of the levers, preferably the positively driven lever, can be biased by a spring element in one of its end positions of the pivoting movement. Here you will select the end position in which the backrest is placed vertically. The bias by the spring element ensures that the chair is moved back into a defined position when it is not loaded.

Das Federelement bestimmt außerdem die Kraft, die ein Benutzer des Stuhls ausüben muss, um die Rückenlehne und den Sitz in ihrer Position zu verstellen. Um diese Kraft auf Personen unterschiedlichen Körpergewichts einstellen zu können, kann der Anlenkpunkt des Federelements am Hebel verstellbar sein.The spring element also determines the force a user of the chair must exert to adjust the backrest and seat in position. In order to adjust this force to persons of different body weight, the point of articulation of the spring element on the lever can be adjusted.

Da der Hebel bei der Verstellung der Rückenlehne und des Sitzes verschwenkt, bewegt sich auch der Anlenkpunkt des Federelements. Damit dieser Anlenkpunkt in seiner voreingestellten Position am Hebel fixiert bleibt und sich während der Bewegung des Hebels nicht wieder verstellt, kann ein Klemmhebel mit einer Kulissenführung vorgesehen sein. In die Kulissenführung kann ein am Rückenlehnenträger angeordneter Stift oder dergleichen eingreifen.Since the lever is pivoted in the adjustment of the backrest and the seat, and the articulation point of the spring element moves. So that this pivot point remains fixed in its preset position on the lever and does not move again during the movement of the lever, a clamping lever may be provided with a slotted guide. In the slotted guide can engage a arranged on the backrest support pin or the like.

Weiterhin kann die Stellung des Hebels und damit die Sitz- und Rückenlehnenposition in einer gewünschten Stellung durch den Benutzer des Stuhls arretierbar sein. Hierzu lässt sich beispielsweise ein Rastschieber einsetzen. Dieser kann am Rückenlehnenträger angeordnet sein und mit der Verzahnung des Basisträgers in Eingriff gebracht werden. Dadurch wird die Position des Rückenlehnenträgers und des mit ihm über die Hebel gekoppelten Sitzträgers bezüglich des feststehend angeordneten Basisträgers fixiert.Furthermore, the position of the lever and thus the seat and backrest position can be locked in a desired position by the user of the chair. For this purpose, for example, a locking slide can be used. This can be arranged on the backrest support and be brought into engagement with the toothing of the base support. As a result, the position of the backrest support and the seat support coupled with it via the lever is fixed relative to the stationary base support.

Zur besseren Anpassung des Sitzmöbels an Personen mit unterschiedlich langen Unterschenkeln kann zudem die Sitzvorderkante über ein Verstellglied absenkbar sein.For better adaptation of the chair to persons with different lengths lower legs also the seat front edge can be lowered via an adjusting.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Sitzmöbels anhand der Zeichnung näher beschrieben.Hereinafter, a preferred embodiment of a seat according to the invention will be described in more detail with reference to the drawing.

Die Zeichnung zeigt in den verschiedenen Figuren jeweils einen Bürostuhl 20 mit einem Sitz 21 und einer Rückenlehne 22. Wie Fig. 1 zeigt, weist der Bürostuhl 20 eine Stuhlsäule 23 auf, an deren unterem Ende ein hier nicht dargestelltes Fußkreuz mit Laufrollen angeordnet sein kann. Am oberen Ende der Stuhlsäule 23 ist ein Basisträger 4 befestigt. An diesem ist ein Rückenlehnenträger 3 gelenkig gelagert. Der Sitz 21 ruht auf einem Sitzträger 1, der mit dem Rückenlehnenträger 3 über zwei Hebel 7 und 6 gelenkig verbunden ist. Der Basisträger 4 und der Hebel 7 weisen jeweils eine Verzahnung 4.1 und 7.1 auf, die ineinander greifen. Die Verzahnungen 4.1 und 7.1 liegen jeweils auf Kreisbogen, sodass der Hebel 7 mit seiner Verzahnung 4.1 auf der Verzahnung 4.1 des Basisträgers 4 wie das Zahnrad eines Planetengetriebes abrollen kann, wenn er verschwenkt wird. Über die Verzahnungen 4.1 und 7.1 ist somit der Hebel 7 und damit die gesamte aus dem Rückenlehnenträger 3, dem Sitzträger 1 und den beiden Hebel in 6, 7 bestehende Synchronmechanik für Sitz 21 und Rückenlehne 22 zwangsgeführt.The drawing shows in the various figures each an office chair 20 with a seat 21 and a backrest 22. As shown in FIG. 1, the office chair 20 has a chair column 23, at the lower end of which a foot cross (not shown) with rollers can be arranged. At the upper end of the chair column 23, a base support 4 is attached. At this a backrest support 3 is articulated. The seat 21 rests on a seat support 1, which is pivotally connected to the backrest support 3 via two levers 7 and 6. The base support 4 and the lever 7 each have a toothing 4.1 and 7.1, which engage with each other. The teeth 4.1 and 7.1 are each on circular arc, so that the lever 7 with its teeth 4.1 on the teeth 4.1 of the base support 4 as the gear of a planetary gear can roll when it is pivoted. Over the teeth 4.1 and 7.1 thus the lever 7 and thus the entire of the backrest support 3, the seat support 1 and the two levers in 6, 7 existing synchronous mechanism for seat 21 and backrest 22 is forcibly guided.

Fig. 1 zeigt den Stuhl 20 mit aufrechter Position der Rückenlehne 22. Der Hebel 7 befindet sich in seiner vordersten Schwenkposition. In dieser ist er durch ein Federelement 8 vorgespannt. Dessen Anlenkpunkt 9 am Hebel 7 ist entsprechend dem Körpergewicht des Benutzers des Stuhls verstellbar. Hierzu weist der Hebel 7 eine zweite Verzahnung 7.2 auf, entlang der der mit einem kleinen Zahnrad versehene Anlenkpunkt 9 auf und ab bewegt werden kann. Je weiter oben sich der Anlenkpunkt 9 befindet, umso stärker ist das Federelement 8 vorgespannt, d. h. umso stärker ist die Kraft, die benötigt wird, die Rückenlehne 22 nach hinten abzusenken. Für leichtere Personen ist es daher zweckmäßig, den Anlenkpunkt 9 gegenüber der in Fig. 1 gezeigten Position nach unten zu verschieben. Damit sich die einmal gewählte Positionen des Anlenkpunkts 9 bezüglich des Hebels 7 nicht mehr verschiebt, wenn der Hebel 7 durch Absenken der Rückenlehne 22 verschwenkt wird, ist ein Klemmhebel 5 mit einer Kulissenführung 5.1 vorgesehen. Der Klemmhebel 5 weist ebenfalls eine Verzahnung auf, in die das Zahnrad des Anlenkpunkts 9 eingreift. In die Kulissenführung 5.1 ragt ein Bolzen oder dergleichen des Rückenlehnenträgers 3 hinein. Dadurch wird der Hebel 5 parallel zum Hebel 7 mit verschwenkt, wenn die Rückenlehne 22 abgesenkt wird, und klemmt den Anlenkpunkt 9 in seiner Position fest.Fig. 1 shows the chair 20 with upright position of the backrest 22. The lever 7 is in its foremost pivot position. In this he is biased by a spring element 8. Its articulation point 9 on the lever 7 is adjustable according to the body weight of the user of the chair. For this purpose, the lever 7 has a second toothing 7.2, along which the articulation point 9 provided with a small toothed wheel can be moved up and down. The farther up the pivot point 9 is, the stronger the spring element 8 is biased, d. H. the stronger the force needed to lower the backrest 22 to the rear. For lighter persons, it is therefore expedient to move the articulation point 9 relative to the position shown in FIG. 1 downwards. Thus, the once selected positions of the pivot point 9 with respect to the lever 7 no longer shifts when the lever 7 is pivoted by lowering the backrest 22, a clamping lever 5 is provided with a slotted guide 5.1. The clamping lever 5 also has a toothing, in which engages the gear of the Anlenkpunkts 9. In the slide guide 5.1 projects a bolt or the like of the backrest support 3 into it. Thereby, the lever 5 is pivoted parallel to the lever 7 with, when the backrest 22 is lowered, and clamps the pivot point 9 in its position.

Fig. 2 zeigt nun den Stuhl 20 aus Fig. 1 mit nach hinten abgesenkter Rückenlehne 22. Die Hebel 6,7 und der Klemmhebel 5 sind in ihre äußerste rechte Position verschwenkt worden. Gleichzeitig zur Rückenlehne 22 hat sich auch der Sitz 21 in seinem hinteren Bereich nach unten abgesenkt. Durch die erfindungsgemäße Synchronmechanik und die Anordnung sämtlicher Drehpunkte der Hebel 6,7 unterhalb der hinteren Hälfte des Sitzes 21 bleibt dabei der hintere Rand des Sitzes 21 stets dicht benachbart zur Rückenlehne 22, sodass es beim Absenken der Rückenlehne und des Sitzes nicht zu einer Verschiebung der Kleidung des Benutzers des Stuhles kommen kann und dessen Rücken auch im Lendenwirbelbereich stets gut abgestützt bleibt.2 now shows the chair 20 of FIG. 1 with the backrest 22 lowered backwards. The levers 6, 7 and the clamping lever 5 have been pivoted into their extreme right position. At the same time to the backrest 22, the seat 21 has lowered in its rear area down. Due to the synchronous mechanism according to the invention and the arrangement of all pivot points of the lever 6,7 below the rear half of the seat 21 while the rear edge of the seat 21 always remains close to the backrest 22 so that it does not shift the seat back and the seat to a shift Clothes of the user of the chair can come and whose back always remains well supported even in the lumbar region.

Fig. 3 verdeutlicht im Schnittbild des Stuhls 20 eine Arretiermöglichkeit der Position von Sitz 21 und Rückenlehne 22. Dazu ist am Rückenlehnenträger 3 ein Rastschieber 12 angeordnet, der mit der Verzahnung 4.1 des Basisträgers 4 in Eingriff gebracht werden kann und damit die weitere Bewegung des Rückenlehnenträgers 3 blockiert.Fig. 3 illustrates in the sectional view of the chair 20 a possibility of locking the position of the seat 21 and backrest 22. For this purpose, a locking slide 12 is arranged on the backrest support 3, which can be brought into engagement with the teeth 4.1 of the base support 4 and thus the further movement of the backrest support 3 blocked.

In Fig. 4 schließlich wird verdeutlicht, wie die vordere Kante des Sitzes 21 entlang der Richtung des Doppelpfeils 24 abgesenkt oder angehoben werden kann. Dazu ist am Sitzträger 1 ein Keilschieber 10 angeordnet, der eine Verzahnung 10.1 aufweist. Mit dieser Verzahnung 10.1 steht ein an einem Bedienhebel 11 angeordnetes Zahnrad in Eingriff. Wird der Bedienhebel 11 nach hinten entlang des Doppelpfeils 25 verschwenkt, so senkt sich die vordere Kante des Sitzes 21 ab, wie in Fig. 4 gezeigt ist. Fig. 1 zeigt dagegen den Bedienhebel 11 in seiner vorderen Schwenkposition. Jetzt ist die Vorderkante des Sitzes 21 gegenüber der Position in Fig. 4 angehoben. Auf diese Weise lässt sich der Stuhl 20 an Personen mit unterschiedlich langen Unterschenkeln auf einfache Weise anpassen.In Fig. 4, finally, it is illustrated how the front edge of the seat 21 can be lowered or raised along the direction of the double arrow 24. For this purpose, a wedge slide 10 is arranged on the seat support 1, which has a toothing 10.1. With this toothing 10.1 is arranged on an operating lever 11 gear engaged. If the operating lever 11 is pivoted backwards along the double arrow 25, then the front edge of the seat 21 is lowered, as shown in FIG. 4. Fig. 1, however, shows the operating lever 11 in its front pivot position. Now the front edge of the seat 21 is raised relative to the position in FIG. 4. In this way, the chair 20 can be easily adapted to people with different lengths lower legs.
