Abstract
Description
Die vorliegende Erfindung betrifft ein Sitzmöbel, insbesondere einen Bürostuhl, mit einer Rückenlehne mit Lumbalstütze.The The present invention relates to seating furniture, 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 designs of lumbar supports attached to the backrests indicate the Disadvantage of a comparatively low flexibility. hereby leads the Use of lumbar supports often too uncomfortable pressure points on the back of the seated person. Furthermore are the well-known lumbar supports only adjustable in height in a small setting range.
Aufgabe der vorliegenden Erfindung ist es, Sitz- und Bedienkomfort eines Sitzmöbels zu verbessern. Diese Aufgabe wird durch ein Sitzmöbel nach Anspruch 1 gelöst.task The present invention is a seat and ease of use seating furniture to improve. This task is achieved by seating furniture 1 solved.
Eine Grundidee der Erfindung ist es danach, die Lumbalstütze an einem flexiblen Führungsband höhenverstellbar anzuordnen. 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 then the lumbar support on one flexible guide band adjustable in height to arrange. The arrangement on a guide belt has compared to the known from the prior art fastening techniques of lumbar supports Advantage that the position of the lumbar support can be changed in a particularly simple manner. For example with a lumbar support clamp on the guide band a height adjustment easy to move. On the other hand, the flexible design of the guide belt Avoid excessive pressure on the back of the seated person. The lumbar support in other words, gives way to the pressure of the seated person, causing the sitting experience is significantly improved.
