Abstract
Eine Verriegelungsvorrichtung für verstellbare wenigstens eine Kopfstützstange (4) aufweisende Kopfstützen für eine Rückenlehne eines Fahrzeugsitzes weist eine Drehverriegelung auf, durch die wenigstens eine Kopfstützstange (4) in einer gewünschten Position arretierbar ist. Die Drehverriegelung erfolgt mit Hilfe einer Verriegelungskugel (19), die in einem die Kopfstützstange (4) umgebenden Grundkörper (10) aufgenommen ist und radial von einer den Grundkörper (10) umgebenden Drehhülse (12) beaufschlagt ist. In der Verriegelungsstellung stellt die Verriegelungskugel (19) zwischen dem Grundkörper (10) und der Kopfstützstange (4) einen Formschluss her, der durch Drehen der Drehhülse (12) in eine die Kopfstützstange (4) freigebende Drehlage aufhebbar ist.A locking device for adjustable headrests, which have at least one headrest rod (4) for a backrest of a vehicle seat, has a rotary lock by means of which at least one headrest rod (4) can be locked in a desired position. The rotary locking takes place with the aid of a locking ball (19) which is received in a base body (10) surrounding the head support rod (4) and is radially acted upon by a rotary sleeve (12) surrounding the base body (10). In the locking position, the locking ball (19) creates a positive fit between the base body (10) and the head support rod (4), which can be canceled by turning the rotary sleeve (12) into a rotational position that releases the head support rod (4).
Description

Die Aufgabe der vorliegenden Erfindung besteht darin, eine weitere Verriegelungsvorrichtung für eine verstellbare Kopfstütze eines Fahrzeugsitzes anzugeben, die einfach herstellbar, montierbar und bedienbar ist.The The object of the present invention is a further locking device for one adjustable headrest specify a vehicle seat, which is easy to manufacture, assemble and is operable.
Die Aufgabe wird durch die Erfindung nach Anspruch 1 gelöst.The The object is solved by the invention according to claim 1.
Vorteilhafte und zweckmäßige Weiterbildungen der Aufgabenlösung sind in den Unteransprüchen angegeben.advantageous and appropriate training the task solution are in the subclaims specified.
Die Erfindung gibt als Verriegelungsvorrichtung eine Drehverriegelung an, mit der einerseits eine Abnahmesicherung und andererseits eine Höhenverstellung der Kopfstütze realisiert werden kann. Die erfindungsgemäße Drehverriegelung braucht nur auf einer Seite der Kopfstütze eingesetzt zu werden. Auf der anderen Seite kann die Kopfstützstange in einer einfachen Hülse geführt werden. Die erfindungsgemäße Verriegelungsvorrichtung besteht aus mehreren einfach herzustellenden Teilen, die miteinander verclipsbar sind, wobei zur Verwendung an verschiedenen Lehnenoberkanten lediglich ein Teil entsprechend umgestaltet und angepasst zu werden braucht, während alle anderen Teile der Verriegelungsvorrichtung gleich bleiben können.The Invention is as a locking device a twist lock on, on the one hand a safety device and on the other hand a height adjustment the headrest can be realized. The rotation lock invention needs only on one side of the headrest to be used. On the other hand, the head support bar in a simple sleeve guided become. The locking device according to the invention consists of several easy-to-produce parts that can be clipped together are, for use on different backrest edges only a part needs to be redesigned and adapted accordingly while all other parts of the locking device can remain the same.
Die Erfindung soll nachfolgend anhand der beigefügten Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, näher erläutert werden.The Invention will be described below with reference to the accompanying drawings in which embodiment is shown, closer explained become.
