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 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.
Aus 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.The object of the invention is therefore to provide a simple, inexpensive and easy-to-use adjusting 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.This object is achieved in that a transversely extending to the backrest and lumbar support slide is provided with at least one ramped cam surface, which is in operative engagement with a reciprocal ramp-shaped cam surface on the lumbar support.
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.This ensures that the lumbar support by moving the transverse slider to the right or left automatically moves forward or back, so that so that the protrusion in the lumbar region is increased or decreased.
In Ausgestaltung können die Kulissenflächen Rasterpunkte zur individuellen Positionierung aufweisen. Damit wird sichergestellt, dass die gewünschte Vorwölbung der Lordosenstütze sich nicht unbeabsichtigt verändert.In an embodiment, the slide surfaces can have grid points for individual positioning. This ensures 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.Likewise, double-sided end stops to limit the movement of the slider are provided 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.The slider may have on both sides Griffwülste for better usability. The lumbar support is advantageously designed as a movable plastic part in order to obtain the most cost-effective and 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 lumbar support may also be vertically displaceable up and down. This is an adaptation to the size of the user of each 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:
