Definitions
- the invention relates to a chair, in particular an office chair, with a seat mounted on a seat support seat and attached to a backrest support backrest, 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, wherein the front of the two levers is forcibly guided directly on the base support.
- 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 reclining positions of the backrest.
- 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.
- the present invention is therefore based on the object to simplify the known synchronous mechanism constructive while maintaining their favorable properties.
- a chair of the type mentioned which is inventively characterized in that the articulation points of the lever on the backrest support and the seat support are arranged independently of the pivotal position of the lever below the rear half of the seat.
- seating furniture according to the invention can therefore be dispensed with a third lever.
- 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.
- the lever may be forcibly guided via a toothing on the base support.
- the teeth of the 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.
- the articulation points of the levers on the backrest support and on the seat support are arranged independently of the pivoting position of the levers all below the rear half of the seat. In this way, an ergonomic synchronous adjustment of the seat and backrest can be achieved.
- 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.
- a spring element in one of its end positions of the pivoting movement.
- 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.
- a clamping lever may be provided with a slotted guide.
- the slotted guide can engage a arranged on the backrest support pin or the like.
- 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.
- 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.
- the seat front edge can be lowered via an adjusting.
- the drawing shows in the various figures each an office chair 20 with a seat 21 and a backrest 22.
- Wie Fig. 1 shows, the office chair 20 on a chair column 23, at the lower end of a not shown here base with wheels can be arranged.
- a base support 4 is attached at the upper end of the chair column 23, a base support 4 is attached.
- 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 shows the chair 20 in an upright position of the backrest 22.
- the lever 7 is in its forwardmost 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.
- 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 articulation point 9 is, the stronger the spring element 8 is biased, ie the stronger the force required to lower the backrest 22 to the rear.
- the pivot point 9 relative to the in Fig. 1 Move the position shown down.
- 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 Anlenk Vietnameses 9.
- In the slide guide 5.1 projects a bolt or the like of the backrest support 3 into it.
- Fig. 2 now shows the chair 20 off Fig. 1 with backrest 22 lowered backwards.
- the levers 6, 7 and the clamping lever 5 have been pivoted into their extreme right position.
- 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 cause a shift in the lowering of the backrest and the seat Clothes of the user of the chair can come and whose back always remains well supported even in the lumbar region.
- Fig. 3 clarified in the sectional view of the chair 20 a possibility of locking the position of the seat 21 and backrest 22.
- 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 blocks the further movement of the backrest support 3.
- 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.
- 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 lowers, as in Fig. 4 is shown.
- Fig. 1 on the other hand shows the operating lever 11 in its front pivot position. Now the front edge of the seat 21 is opposite to the position in Fig. 4 raised. In this way, the chair 20 can be easily adapted to people with different lengths lower legs.

Abstract
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, wobei der vordere der beiden Hebel unmittelbar am Basisträger zwangsgeführt ist.The invention relates to a chair, in particular an office chair, with a seat mounted on a seat support seat and attached to a backrest support backrest, 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, wherein the front of the two levers is forcibly guided directly on the base support.
Ein solches Sitzmöbel ist aus dem deutschen Gebrauchsmuster
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.
Ein weiteres Beispiel ist aus dem Patentdokument
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 die Anlenkpunkte der Hebel am Rückenlehnenträger und am Sitzträger unabhängig von der Schwenkstellung der Hebel unterhalb der hinteren Hälfte des Sitzes angeordnet sind.The object is achieved by a chair of the type mentioned, which is inventively characterized in that the articulation points of the lever on the backrest support and the seat support are arranged independently of the pivotal position of the lever below the rear half of the seat.
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 the 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 sind unabhängig von der Schwenkstellung der Hebel alle unterhalb der hinteren Hälfte des Sitzes angeordnet. 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 are arranged independently of the pivoting position of the levers 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.
