Description
Die vorliegende Erfindung betrifft ein Sitzmöbel, insbesondere einen Bürostuhl, mit einer Rückenlehne mit Lumbalstütze.The The present invention relates to a chair, in particular an office chair, with a backrest with lumbar support.
Die bisherigen Konstruktionen von an Rückenlehnen angebrachten Lumbalstützen weisen den Nachteil einer vergleichsweise geringen Flexibilität auf. Hierdurch führt die Benutzung von Lumbalstützen oft zu unangenehmen Druckstellen am Rücken des Sitzenden. Darüber hinaus sind die bekannten Lumbalstützen nur in einem kleinen Einstellbereich in ihrer Höhe verstellbar.The previous constructions of lumbar supports attached to the backrest have the Disadvantage of a comparatively low flexibility. hereby leads the Use of lumbar supports often to unpleasant pressure points on the back of the sitter. Furthermore are the known lumbar supports adjustable in height only in a small adjustment range.

Demgegenüber ist es eine Aufgabe der vorliegenden Erfindung, den Sitz- und Bedienkomfort eines Sitzmöbels zu verbessern. Diese Aufgabe wird durch ein Sitzmöbel mit den Merkmalen des Patentanspruchs 1 gelöst.In contrast, is It is an object of the present invention, the seating and operating comfort a chair to improve. This task is accompanied by a seating the features of claim 1.
Eine Grundidee der Erfindung ist es danach, die Lumbalstütze an einem flexiblen Führungsband höhenverstellbar anzuordnen. Das Führungsband ist vorgespannt und die Vorspannung ist veränderbar. Die Anordnung an einem Führungsband hat gegenüber den aus dem Stand der Technik bekannten Befestigungstechniken von Lumbalstützen den Vorteil, daß zum einen die Position der Lumbalstütze auf besonders einfache Art und Weise verändert werden kann. So ist beispielsweise bei einer Klemmhalterung der Lumbalstütze an dem Führungsband eine Höhenverstellung durch einfaches Verschieben möglich. Zum anderen wird durch die flexible Ausgestaltung des Führungsbandes eine zu starke Druckbelastung am Rücken des Sitzenden vermieden. Die Lumbalstütze gibt mit anderen Worten dem Druck des Sitzenden nach, wodurch das Sitzgefühl wesentlich verbessert wird.A The basic idea of the invention is thereafter, the lumbar support on a flexible guide band height adjustable to arrange. The leader band is preloaded and the bias is variable. The arrangement at one guide band has opposite known from the prior art fastening techniques of lumbar support the advantage that to one the position of the lumbar support can be changed in a particularly simple way. Such is for example in a clamping bracket of the lumbar support on the guide band a height adjustment possible by simply moving. On the other hand, the flexible design of the guide band Too much pressure on the back of the sitting avoided. The lumbar support In other words, it replies the pressure of the sitter, causing the sitting experience is significantly improved.
