Description

Die Erfindung betrifft einen Stuhl, insbesondere einen Bürostuhl, mit einem gegenüber der Horizontalen neigbaren Sitzträger und einem synchron zur Neigung des Sitzträgers in seiner Neigung verstellbaren Rückenlehnenträger.The invention relates to a chair, in particular an office chair, with a seat bracket that can be tilted in relation to the horizontal and one in sync with the inclination of the seat support in his Adjustable backrest support.

Bei der Synchronverstellung der Sitzfläche und der Rückenlehne eines Stuhles ist aus ergonomischen Gesichtspunkten darauf zu achten, daß die Vorderkante der Sitzfläche bei der Kippbewegung nach hinten in möglichst unveränderter Stellung bleibt und daß sich der Winkel zwischen Rückenlehne und Sitzfläche beim Nachhintenneigen vergrößert. Zur Befriedigung dieser Anforderungen sind bereits unterschiedliche Mechanismen vorgeschlagen worden, die jedoch alle einen relativ hohen konstruktiven Aufwand erfordern.With the synchronous adjustment of the seat and backrest a chair is approached from an ergonomic point of view make sure that the front edge of the seat surface tilts remains in the unchanged position to the rear and that the angle between the backrest and seat enlarged when leaning back. To satisfy this Different mechanisms have already been proposed for requirements been, however, all of a relatively high constructive Require effort.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Stuhl mit einer Synchronverstellmechanik der Sitzfläche und der Rückenlehne zu schaffen, der konstruktiv weniger aufwendig ist als die seither bekannten Lösungen. The present invention has for its object a Chair with a synchronous adjustment mechanism of the seat and to create the backrest that is less constructive than the solutions known since then.

Die Aufgabe wird mit einem Stuhl der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß der Sitzträger und der Rückenlehnenträger aus einem mindestens bereichsweise elastisch federnden Bauteil gebildet sind und der Sitzträger aus einem im wesentlichen U-förmig gebogenen Bereich des Bauteiles besteht, wobei einer der Schenkel des U-förmigen Sitzträgers an einer Stuhlsäule angeordnet ist. Durch die einteilige Ausbildung von Sitzträger und Rückenlehnenträger entfallen die bei herkömmlichen Stühlen erforderlichen Montagearbeiten. Der gesamte Stuhl besteht aus Wenigen Einzelkomponenten, die rasch zusammenbaubar sind. Durch die U-förmige Ausbildung des Sitzträgers erhält dieser die notwendige Flexibilität. Zweckmäßigerweise sind dabei die Schenkel des U-förmigen Sitzträgers in ihrem Endbereich über ein Verbindungselement miteinander gekoppelt. Das Verbindungselement kann elastisch sein, so daß eine ungehinderte aber gesteuerte Übertragung der Bewegung des Sitzträgers auf den Rückenlehnenträger möglich ist. Die Vorderkante der die Sitzfläche des Stuhles bildenden Basis des U-förmigen Sitzträgers kann vorteilhafterweise flexibel ausgebildet und an einer mit der Stuhlsäule verbundenen Führungsbahn geführt sein. Hierdurch ist ein Absenken der Sitzfläche nach hinten möglich, ohne daß sich die Höhe der Vorderkante der Sitzfläche ändert, was zu einem unangenehmen Druck auf die Beine des Benutzers im Bereich der Kniekehlen führen würde. Neben der federnden Lagerung kann der Schenkel des U-förmigen Sitzträgers auch um eine horizontale Achse begrenzt verschwenkbar an der Stuhlsäule angeordnet sein. Dabei ist es möglich, den Sitzträger und den Rückenlehnenträger begrenzt nach vorne verschwenkbar an der Stuhlsäule zu lagern, um den Rücken des Benutzers auch bei einer nach vorne gebeugten Arbeitshaltung gut zu unterstützen. Die Neigung des Sitzträgers und des Rückenlehnenträgers kann dabei auch arretierbar eingestellt werden. Um den erfindungsgemäßen Stuhl an Personen unterschiedlichen Körpergewichts anpassen zu können, können Vorrichtungen zur körpergewichtsabhängigen Einstellung der Empfindlichkeit der Synchronverstellung an Rückenlehne und Sitzträger angeordnet sein. Hierzu kann beispielsweise die Steifigkeit des an der Stuhlsäule angeordneten Schenkels des Sitzträgers mittels einer entlang des Schenkels verschiebbaren Hülse körpergewichtsabhängig einstellbar sein. Durch Verschieben der Hülse wird die Biegezone des Schenkels in der Länge variiert und somit die Steifigkeit des Schenkels eingestellt. Der Stuhl kann außerdem Arretiervorrichtungen für die Neigung des Sitz- und des Rückenlehnenträgers aufweisen. Auch die Tiefe der Sitzfläche kann einstellbar sein.The task is carried out with a chair of the type mentioned at the beginning solved according to the invention in that the seat support and Backrest support made of an elastic at least in some areas resilient component are formed and the seat support an essentially U-shaped area of the component consists of one of the legs of the U-shaped seat support is arranged on a chair column. Through the one-piece training the seat support and backrest support are omitted assembly work required for conventional chairs. Of the Entire chair consists of a few individual components that are quick can be assembled. Due to the U-shaped design of the seat support this gets the necessary flexibility. Conveniently are the legs of the U-shaped seat support in their end region coupled to one another via a connecting element. The connecting element can be elastic, so that an unimpeded but controlled transmission of the movement of the Seat support on the backrest support is possible. The leading edge the base of the U-shaped part forming the seat of the chair Seat carrier can advantageously be flexible and on a guideway connected to the chair column be led. This is a lowering of the seat possible to the rear without changing the height of the front edge The seat changes, causing an uncomfortable pressure on the Would lead the user's legs in the area of the hollow of the knees. In addition to the resilient mounting, the leg of the U-shaped Seat carrier can also be pivoted to a limited extent about a horizontal axis be arranged on the chair column. It is possible to limit the seat support and the backrest support to be pivoted forward on the chair column to support the Back of the user even when the work posture is bent forward to support well. The inclination of the seat support and the backrest support can also be locked will. To the chair according to the invention on people to be able to adapt to different body weights Devices for body weight-dependent adjustment of the Sensitivity of the synchronous adjustment on the backrest and Seat support can be arranged. For example, the Stiffness of the leg of the Seat carrier by means of a slidable along the leg Sleeve can be adjusted depending on body weight.

Der Stuhl 10 nach Fig. 1 weist einen Rückenlehnenträger 11 auf, der einteilig mit einem Sitzträger 12 ausgebildet ist. Das den Rückenlehnenträger 11 und den Sitzträger 12 bildende Bauteil 13 ist im Bereich des Sitzträgers 12 U-förmig gebogen. Ein Schenkel 14 des U-förmigen Sitzträgers 12 ist über ein Lager 15 mit einer Stuhlsäule 16 verbunden, die in einem Fußkreuz 17 höhenverstellbar angeordnet ist. Der Schenkel 14 des U-förmigen Sitzträgers 12 ist mit dem zweiten Schenkel 18 über ein Verbindungselement 19 elastisch verbunden. Im Bereich der Vorderkante des Stuhles 10 weist der Sitzträger 12 eine flexible Zone 20 auf. In diesem Bereich ist der Sitzträger 12 an einer bogenförmigen Führungsbahn 21 geführt, die mit der Stuhlsäule 16 verbunden ist. Hierdurch ist gewährleistet, daß bei einer Verstellung der Neigung des Sitzträgers 12 die Vorderkante des Stuhles 10 in der Höhe nicht verändert wird. Im dargestellten Beispiel ist der Schenkel 14 des Sitzträgers 12 an einer arretierbaren Achse 22 an der Stuhlsäule 16 gelagert, die auch ein Verschwenken des Sitzträgers 12 nach vorne erlaubt. Die beiden extremsten Neigungsstellungen des Stuhles 10 sind in Fig. 3 dargestellt. Der Sitzträger 12 ist um einen Winkel α unter die Horizontale 30 absenkbar und um einen Winkel β gegenüber der Horizontalen 30 anhebbar. Bei dem in Fig. 3 mit durchgezogenen Linien angezeigten maximalen Absenken des Sitzträgers 12 bildet der Sitzträger 12 mit dem Rückenlehnenträger 11 einen Winkel δ, der größer ist als der Winkel γ zwischen dem Sitzträger 12 und dem Rückenlehnenträger 11 in Ruhestellung des Sitzträgers 12, wie Fig. 2 verdeutlicht. Die Vorderkante 20 des Stuhles 10 ändert ihre Höhe beim Absenken des Sitzträgers 12 unter die Horizontale 30 nicht. Die verschiedenen Neigungsstellungen des Sitz- und des Rückenlehnenträgers können mittels einer Klemmvorrichtung 31 arretiert werden. Zur Einstellung der notwendigen Verstellkraft der Synchronverstellung in Abhängigkeit vom Körpergewicht des Benutzers des Stuhles ist der Schenkel 14 des U-förmigen Sitzträgers 12 mit einer Hülse 23 versehen, die längs des Schenkels 14 verschiebbar ist (Fig. 4, 5). Ist die Hülse 23, wie in Fig. 4 gezeigt, möglichst weit nach hinten geschoben, so erhält der Biegebereich 24 des Schenkels 14 seine größte Ausdehnung. Die Synchronverstellung benötigt einen nur geringen Kraftaufwand. Wird die Hülse 23, wie in Fig. 5 gezeigt, nach vorne geschoben, so verkleinert sich der Biegebereich 24 entsprechend, wodurch eine Verstellung der Synchronmechanik nur mit einem relativ großen Kraftaufwand möglich ist. Die körpergewichtsabhängige Einstellung der Synchronverstellung mit der Hülse 23 stellt eine konstruktiv einfache und leicht zu bedienende Lösung dar. Selbstverständlich kann die Hülse 23 auch arretierbar sein. Fig. 6 zeigt einen Sitzträger 12 mit einer Möglichkeit zur Sitztiefenverstellung. Aufgrund des flexiblen Bereiches 20 an der Vorderkante des Sitzträgers 12 läßt sich die Tiefe des Sitzträgers 12 durch eine beispielsweise teleskopartige Verlängerung der Führungsbahn 21 um maximal den Betrag d vergrößern.1 has a backrest support 11 on, which is formed in one piece with a seat support 12. That forming the backrest support 11 and the seat support 12 Component 13 is bent in a U-shape in the area of the seat support 12. One leg 14 of the U-shaped seat support 12 is over a Bearing 15 connected to a chair column 16, which is in a base 17 is arranged adjustable in height. The leg 14 of the U-shaped seat support 12 is over with the second leg 18 a connecting element 19 is elastically connected. In the field of The front edge of the chair 10, the seat support 12 has a flexible Zone 20 on. In this area the seat support 12 is on an arcuate guide track 21, which with the Chair column 16 is connected. This ensures that when adjusting the inclination of the seat support 12, the front edge the height of the chair 10 is not changed. in the The example shown is the leg 14 of the seat support 12 mounted on a lockable axis 22 on the chair column 16, which also allows pivoting of the seat support 12 to the front. The two most extreme inclination positions of the chair 10 are shown in Fig. 3. The seat support 12 is one Angle α can be lowered below the horizontal 30 and by an angle β can be raised relative to the horizontal 30. At the in Fig. 3 shown with solid lines maximum subsidence the seat support 12 forms the seat support 12 with the Backrest support 11 has an angle δ which is greater than that Angle γ between the seat support 12 and the backrest support 11 in the rest position of the seat support 12, as shown in FIG. 2. The front edge 20 of the chair 10 changes its height when Do not lower the seat support 12 below the horizontal 30. The different inclinations of the seat and backrest support can be locked by means of a clamping device 31 will. To set the necessary adjustment force the synchronous adjustment depending on the body weight of the The user of the chair is the leg 14 of the U-shaped seat support 12 provided with a sleeve 23, which is along the leg 14 is displaceable (Fig. 4, 5). Is the sleeve 23, as in Fig. 4 shown pushed as far back as possible the bending area 24 of the leg 14 has its greatest extent. The synchronous adjustment requires only a small amount Effort. The sleeve 23, as shown in Fig. 5, after pushed forward, the bending area 24 is reduced accordingly, whereby an adjustment of the synchronous mechanism only is possible with a relatively large amount of force. The body weight dependent Setting the synchronous adjustment with the Sleeve 23 represents a structurally simple and easy to use Solution. Of course, the sleeve 23 can also be lockable. Fig. 6 shows a seat support 12 with a Possibility of seat depth adjustment. Because of the flexible Area 20 on the front edge of the seat support 12 can be the depth of the seat support 12 by, for example, a telescopic Extension of the guideway 21 by a maximum of Increase amount d.
