Description
Die vorliegende Erfindung betrifft eine Arretiervorrichtung mit einem Arretiermittel, das relativ zu mindestens zwei eine Mehrzahl von Ausnehmungen aufweisenden Haltestangen reversibel von einer Freigabestellung in eine Arretierstellung bewegbar ist, wobei es in der Arretierstellung jeweils arretierend mit den Ausnehmungen zusammenwirkt und bei der das Arretiermittel mit einem Federmittel zusammenwirkt, das in der Arretierstellung vorgespannt und in der Freigabestellung im Vergleich zur Arretierstellung stärker gespannt ist.The present invention relates to a locking device with a locking means which is movable relative to at least two retaining recesses having a plurality of recesses reversibly from a release position to a locking position, wherein it cooperates in the locking position each arresting with the recesses and in which the locking means with a spring means cooperates, which is biased in the locking position and in the release position in comparison to the locking position is more tensioned.
Des Weiteren betrifft die vorliegende Erfindung einen Kraftfahrzeugsitz aufweisend die erfindungsgemäße Arretiervorrichtung.Furthermore, the present invention relates to a motor vehicle seat comprising the locking device according to the invention.
Die Kopfstützen an Kraftfahrzeugsitzen, wie sie beispielsweise in der
Es hat deshalb nicht an Versuchen gefehlt, derartige Arretierungsvorrichtungen zur Verfügung zu stellen. Beispielsweise werden in der
Es war deshalb die Aufgabe der vorliegenden Erfindung, eine Arretiervorrichtung zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist.It was therefore the object of the present invention to provide a locking device which does not have the disadvantages of the prior art.
Gelöst wird die Aufgabe mit einer Arretiervorrichtung gemäß Patentanspruch 1.The problem is solved with a locking device according to claim 1.
Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass die erfindungsgemäße Arretiervorrichtung vergleichsweise leicht zu entriegeln ist, dass aber aufgrund der Vorspannung des Federmittels gleichzeitig eine sichere Arretierung der Haltestangen, an denen beispielsweise eine Kopfstütze angeordnet ist, sichergestellt ist.It was extremely surprising and unexpected for the skilled person that the locking device according to the invention is relatively easy to unlock, but that due to the bias of the spring means at the same time a secure locking of the support rods on which, for example, a headrest is arranged, is ensured.
Erfindungsgemäß weist die Vorrichtung ein Arretiermittel auf, das relativ zu zumindest zwei Haltestangen von einer Arretier- in eine Freigabestellung verschiebbar ist. Die Haltestangen weisen eine Mehrzahl von Ausnehmungen auf, die in der Arretierstellung mit dem Arretiermittel form- und/oder kraftschlüssig so zusammenwirken, dass die Haltestangen relativ zu dem Arretiermittel nicht verschiebbar sind. Des Weiteren weist die erfindungsgemäße Arretiervorrichtung ein Federmittel auf, das mit dem Arretiermittel zusammenwirkt und dieses in der Arretierstellung in die Ausnehmungen hinein vorspannt, so dass auch bei Erschütterungen oder einem Unfall sichergestellt ist, dass sich die Arretierung zwischen dem Arretiermittel und den Haltestangen nicht löst; d. h. der Form- und/oder Kraftschluß zwischen dem Arretiermittel und den Ausnehmungen nicht aufgehoben wird. Des Weiteren bewirkt die Vorspannung, dass zwischen dem Arretiermittel und den Haltestangen keine Geräuschentwicklung auftritt. In der Freigabestellung ist das Federmittel im Vergleich zur Arretierung stärker gespannt bzw. weist in dieser Stellung seine maximale Deformation auf.According to the invention, the device has a locking means, which is displaceable relative to at least two support rods from a locking into a release position. The support rods have a plurality of recesses which positively and / or non-positively cooperate in the locking position with the locking means such that the support rods are not displaceable relative to the locking means. Furthermore, the locking device according to the invention on a spring means which cooperates with the locking means and biases it in the locking position in the recesses, so that it is ensured even with shock or an accident that does not solve the lock between the locking means and the support rods; d. H. the positive and / or frictional connection between the locking means and the recesses is not canceled. Furthermore, the bias causes no noise to occur between the locking means and the support rods. In the release position, the spring means is more taut compared to the lock or has in this position its maximum deformation.
Als Federmittel eignet sich jedes dem Fachmann bekannte Federmittel. Vorzugsweise handelt es sich bei dem Federmittel jedoch um eine Blattfeder, die an zwei Punkten mit dem Arretiermittel zusammenwirkt und die in der Mitte an einem Gehäuse oder dergleichen gelagert ist.As spring means, any spring known in the art is suitable. Preferably, however, the spring means is a leaf spring which cooperates at two points with the locking means and which is mounted in the middle on a housing or the like.
Erfindungsgemäß weist die Arretiervorrichtung weiterhin ein Verstellmittel auf, welches das Arretiermittel von der Arretier- in die Freigabestellung bewegt und dort fixiert. Diese Entriegelung des Arretiermittels kann beispielsweise durch eine Schiebe- oder Drehbewegung des Verstellmittels erfolgen. Sobald dieses Verstellmittel wieder in die entgegengesetzte Richtung bewegt wird, verschiebt sich das Arretiermittel von der Freigabestellung in die Arretierstellung zurück.According to the invention, the locking device further comprises an adjusting means which moves the locking means from the locking to the release position and fixed there. This unlocking of the locking means can be done for example by a sliding or rotary movement of the adjusting means. As soon as this adjusting means is moved again in the opposite direction, the locking means shifts from the release position to the locking position.
Vorzugsweise wirken das Arretiermittel und das Verstellmittel an mindestens zwei Stellen gleichzeitig zusammen.Preferably, the locking means and the adjusting act at least two places together at the same time.
In einer weiteren bevorzugten Ausführungsform ist das Arretiermittel federnd gestaltet.In a further preferred embodiment, the locking means is resilient.
Die erfindungsgemäße Arretiervorrichtung eignet sich insbesondere zur Arretierung einer Kopfstütze relativ zu der Lehne eines Kraftfahrzeugsitzes. Ein weiterer Gegenstand der vorliegenden Erfindung ist deshalb ein Kraftfahrzeugsitz, der die erfindungsgemäße Arretiervorrichtung aufweist.The locking device according to the invention is particularly suitable for locking a headrest relative to the back of a motor vehicle seat. Another object of the present invention is therefore a motor vehicle seat having the locking device according to the invention.
Vorzugsweise dient die Arretiervorrichtung zur Halterung einer Kopfstütze, die an dem Kraftfahrzeugsitz angeordnet ist und diese in der jeweils gewünschten Höheneinstellung arretiert.Preferably, the locking device is used to hold a headrest, which is arranged on the motor vehicle seat and locks it in the respectively desired height adjustment.
Im Folgenden wird die Erfindung anhand der

Die erfindungsgemäße Arretiervorrichtung hat den Vorteil, dass insbesondere die Erzeugung der Freigabestellung mit vergleichsweise geringen Kräften erfolgen kann und somit manuell sehr komfortabel bewerkstelligt werden kann. Durch die permanente Vorspannung des Federmittels
