Abstract

The armrest consists of an arm support (3) on the top of, and the same length as, an elongated base (2). The arm support can swivel in relation to the base on a vertical axle (4) at the back of the base. The arm support's swivel movement is restricted by a circle-arc shaped cavity with centre through the vertical axle into which a guide pin (6) protrudes. The cavity is positioned on the arm support's underside and has the guide pin protruding into it beyond the top of the base. A preferably spring loaded clutch (7) fits into one of several holders inside the rim support's path of movement.

Description

Die Erfindung betrifft eine Armlehne für Sessel oder Stühle, enthaltend einen länglichen Basiskörper und eine an der Oberseite des Basiskörpers angebrachte Armstütze, die im wesentlichen die gleiche Länge wie der Basiskörper aufweist und relativ zum Basiskörper um eine Vertikalachse seitlich verschwenkbar ist, die im Bereich des hinteren Endes des Basiskörpers angebracht ist.The invention relates to an armrest for armchairs or chairs containing an elongated Base body and an armrest attached to the top of the base body, the has substantially the same length as the base body and relative to the base body is laterally pivotable about a vertical axis in the area of the rear end of the base body is attached.

Bei einer derartigen, in der US-A-4 576 351 beschriebenen Armlehne wird die Vertikalachse durch eine Schraube gebildet, die durch den Basiskörper in die Unterseite der Armstütze eingeschraubt ist. Zum Verschwenken der Armstütze muß diese Schraube gelöst und anschließend zur Arretierung der Armlehne wieder in die Armstütze eingeschraubt werden. Dieses Lösen und Wiederanziehen der Schraube setzt den Bedienungskomfort beim Verstellen der Armstütze herab, was häufig dazu führt, daß auf eine körpergerechte Einstellung der Armstütze verzichtet wird. In such an armrest, described in US-A-4,576,351, the vertical axis becomes formed by a screw that goes through the base body into the bottom of the Armrest is screwed in. This screw must be used to pivot the armrest loosened and then screwed back into the armrest to lock the armrest become. This loosening and tightening of the screw ensures ease of use when adjusting the armrest down, which often leads to a appropriate adjustment of the armrest is dispensed with.

Aus der DE-A-2 507 848 ist eine Armstütze bekannt, die auf einer Horizontalachse schwenkbar gelagert ist, die mittels einer Lasche seitlich fest mit einer Sitzrückenlehne verbunden ist. Die Armstütze ist um die Horizontalachse zwischen einer abgeklappten Lage und einer hochgeschwenkten Lage verschwenkbar. Der Schwenkbereich der Armstütze wird begrenzt durch eine fest mit der Horizontalachse verbundene Anschlagplatte, die mit zwei Führungsschlitzen versehen ist, in die zwei seitlich an der Armstütze angebrachte Anschlagbolzen ragen. Zur Arretierung der Armstütze in der hochgeschwenkten Lage einerseits und gegebenenfalls auch in der abgeklappten Lage andererseits dienen an den freien Enden der beiden Anschlagbolzen angebrachte Bunde, die in den Endstellungen der Armstütze unter Einwirkung einer Feder in zugeordnete, als Bohrungen ausgebildete Aussparungen der Anschlagplatte einrasten. Die Bohrungen sind jeweils im Bereich der Endpunkte der beiden Führungsschlitze angeordnet. Das Lösen der Arretierung erfolgt manuell durch Druck auf die Armstütze im Bereich einer einclipsbaren Abdeckplatte, wodurch die Feder zusammengedrückt wird und damit die freien Enden der beiden Anschlagbolzen mit ihrem Bund in gleicher Richtung aus den Bohrungen der Anschlagplatte herausbewegt werden.From DE-A-2 507 848 an armrest is known which is on a horizontal axis is pivotally mounted, which is fixed laterally with a seat back by means of a tab connected is. The armrest is folded down about the horizontal axis Location and a pivoted up position. The swivel range of the Armrest is limited by a stop plate firmly connected to the horizontal axis, which is provided with two guide slots in the two on the side of the armrest attached stop pins protrude. To lock the armrest in the swiveled up position Position on the one hand and possibly also in the folded position on the other hand serve bundles attached to the free ends of the two stop bolts, the assigned in the end positions of the armrest under the action of a spring, as Snap the holes in the stop plate into the holes. The holes are each arranged in the area of the end points of the two guide slots. The The lock is released manually by pressing the armrest in the area a clip-on cover plate, which compresses the spring and thus the free ends of the two stop bolts with their collar in the same direction be moved out of the holes in the stop plate.
