Abstract
Description
Die Erfindung betrifft eine Verstellvorrichtung für eine Lordosenstütze in einer Rückenlehne, insbesondere für Bürostühle mit einem im Wesentlichen flächigen Stützteil und einer verstellbaren Lordosenstütze.The The invention relates to an adjusting device for a lumbar support in a backrest, in particular for office chairs with a substantially flat support member and an adjustable lumbar support.

der
Eine
derartige Ausgestaltung ist ausgesprochen aufwendig und kostenintensiv.
Sie kommt insbesondere für Bürostühle,
die in großer Auflage hergestellt und verkauft werden,
nicht in Betracht. Dasselbe gilt für die aus der
Aufgabe der Erfindung ist es daher, eine möglichst einfache, kostengünstige und leicht zu bedienende Verstellvorrichtung bereitzustellen.task The invention is therefore the simplest possible, cost-effective and easy to use adjustment device.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass ein quer zur Rückenlehne und zur Lordosenstütze verlaufender Schieber mit wenigstens einer rampenförmigen Kulissenfläche vorgesehen ist, die mit einer reziproken rampenförmigen Kulissenfläche an der Lordosenstütze im Wirkeingriff steht.These The object is achieved according to the invention that one across the backrest and lumbar support extending slide with at least one ramp-shaped Sliding surface is provided with a reciprocal ramp-shaped backdrop surface on the lumbar support is in operative intervention.
Hiermit wird erreicht, dass die Lordosenstütze durch Verschieben des querlaufenden Schiebers nach rechts oder links sich automatisch nach vorne oder hinten bewegt, so dass damit die Vorwölbung im Lordosenbereich vergrößert oder verkleinert wird.Herewith is achieved by moving the lumbar support of the transverse slider to the right or left automatically moves forward or backward, allowing the protrusion enlarged or reduced in the lordosis area becomes.
In Ausgestaltung können die Kulissenflächen Rasterpunkte zur individuellen Positionierung aufweisen. Damit wird sichergestellt, dass die gewünschte Vorwölbung der Lordosenstütze sich nicht unbeabsichtigt verändert.In Design, the backdrop surfaces grid points have for individual positioning. This will ensure that the desired protrusion of the lumbar support does not change unintentionally.
Ebenso sind beidseitige Endanschläge zur Begrenzung der Bewegung des Schiebers vorgesehen, damit dieser nicht ausrastet.As well are double-sided end stops to limit the movement provided the slider so that it does not disengage.
Der Schieber kann zur besseren Bedienbarkeit beidseitige Griffwülste aufweisen. Die Lordosenstütze ist vorteilhaft als bewegliches Kunststoffteil ausgebildet, um eine möglichst kostengünstige und gewichtssparende Lösung zu erhalten.Of the Slider can handle both sides for better usability exhibit. The lumbar support is beneficial as a mobile Plastic part designed to be as cost effective as possible and to obtain a weight-saving solution.
Die Lordosenstütze kann darüber hinaus vertikal auf und ab verschiebbar sein. Damit findet eine Anpassung an die Größe des Benutzers des jeweiligen Sitzes statt.The In addition, lumbar support can be vertical on and be relocatable. This is an adaptation to the size the user of the respective seat instead.
Die Erfindung ist nachstehend anhand der Zeichnung näher erläutert. Diese zeigt in:The Invention is explained below with reference to the drawing. This shows in:
