Abstract

The chair (1) has a backrest (4) connected to a support (2) over a back rest support, where the backrest has an adjustable lumbar support as well as a seat surface (5), which is attached at the support. An inclination position of the backrest and an adjusting position of the lumbar support are coupled with one another over a coupling unit e.g. bowden cable, in such that a downwardly directed tilting movement of the backrest causes a change of the adjusting position of the lumbar support, in particular relaxation of the lumbar support.

Description

Der Erfindung liegt die Aufgabe zugrunde, einen Stuhl anzubieten, der eine besonders komfortable automatische Verstellmöglichkeit bietet.Of the Invention is based on the object to offer a chair, the a particularly comfortable automatic adjustment offers.

Diese Aufgabe wird durch einen Stuhl mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausführungsformen des Stuhls werden in den Unteransprüchen beschrieben.These Task is by a chair with the features of the claim 1 solved. Advantageous embodiments of the chair are described in the subclaims.

Der Stuhl ist anhand von Ausführungsbeispielen in den Zeichnungsfiguren weiter erläutert. Es zeigen:Of the Chair is based on embodiments further explained in the drawing figures. Show it:

1 eine schematische Darstellung eines Stuhls mit aufgerichteter Rückenlehne, 1 a schematic representation of a chair with upright backrest,

2 eine vergrößerte Darstellung von 1, 2 an enlarged view of 1 .

3 eine schematische Darstellung eines Stuhls mit abgekippter Rückenlehne sowie 3 a schematic representation of a chair with tilted backrest and

4 eine vergrößerte Darstellung von 3. 4 an enlarged view of 3 ,

1 und 2 zeigt den Stuhl 1 mit einem Träger 2 in der Position mit senkrecht stehender an einem Lehnenträger 3 angebrachten Rückenlehne 4 und an sich bekannter und z.B. durch einen Seilzug verstellbarer gekrümmter Lumbalstütze 6. 1 and 2 shows the chair 1 with a carrier 2 in the upright position on a backrest support 3 attached backrest 4 and known per se and eg adjustable by a cable curved lumbar support 6 ,

In 3 und 4 wurde die Rückenlehne 4 nach hinten gekippt, die Lumbalstütze 6 ist gerade und entspannt.In 3 and 4 became the backrest 4 tilted back, the lumbar support 6 is straight and relaxed.

Durch Neigung der Rückenlehne wird im Kopplungselement 7 (z.B. einem Seilzug) eine Änderung der Lageposition erzeugt (z.B. Seilfreigabe und Seilverlängerung). Diese wird automatisch in der Lumbalstütze 6 in unterschiedliche Verstellpositionen umgesetzt.By inclination of the backrest is in the coupling element 7 (eg a cable) generates a change in the position position (eg rope release and rope extension). This will automatically be in the lumbar support 6 implemented in different adjustment positions.

Gleichzeitig kann durch das Kippen der Rückenlehne 4 nach hinten die Sitzfläche 5 ebenfalls kippen (z.B. Absenkung der Sitzfläche 5 im vorderen Bereich in Richtung 8).At the same time, by tilting the backrest 4 behind the seat 5 also tilt (eg lowering of the seat 5 in the front area towards 8th ).
