Description

Die Erfindung betrifft einen Kraftfahrzeugschlüssel mit einem Identifikationsgeber zur Betätigung einer Kraftfahrzeugschließanlage über eine Luftschnittstelle, mit einem Gehäuse und einem in einer Ruheposition in dem Gehäuse angeordneten und entnehmbaren Notschlüssel zur mechanischen Betätigung der Kraftfahrzeugschließanlage, wobei der Notschlüssel in seiner Ruheposition von einem ersten Rastelement freigebbar verrastet wird und wobei der Kraftfahrzeugschlüssel eine Freigabetaste aufweist, durch deren Betätigung das erste Rastelement den Notschlüssel freigibt.The invention relates to a motor vehicle key with an identification transmitter for actuating a motor vehicle locking system via an air interface, with a housing and a arranged in a rest position in the housing and removable emergency key for mechanical actuation of the motor vehicle locking system, wherein the emergency key is releasably locked in its rest position by a first locking element and wherein the motor vehicle key has a release button, by the actuation of which the first latching element releases the emergency key.

Derartige Kraftfahrzeugschlüssel zur Betätigung einer Schließvorrichtung eines Kraftfahrzeugs über eine Luftschnittstelle sind bekannt und als Autoschlüssel moderner Kraftfahrzeuge weit verbreitet. Ferner weist ein solcher Schlüssel einen in dem Gehäuse des Schlüssels angeordneten und aus dem Gehäuse entnehmbaren Notschlüssel zur mechanischen Betätigung der Kraftfahrzeugschließanlage auf, der ein Öffnen und Starten des Fahrzeuges in dem Fall ermöglicht, dass eine Betätigung der Schließvorrichtung über eine Luftschnittstelle beispielsweise infolge des Ausfalls einer Batterie nicht mehr möglich ist.Such motor vehicle keys for actuating a locking device of a motor vehicle via an air interface are known and widely used as car keys of modern motor vehicles. Furthermore, such a key has an arranged in the housing of the key and removable from the housing emergency key for the mechanical operation of the motor vehicle locking system, which allows opening and starting the vehicle in the event that actuation of the closure device via an air interface, for example due to the failure of a Battery is no longer possible.

Dabei wird der Notschlüssel in seiner Ruheposition von einem ersten Rastelement freigebbar verrastet und der Kraftfahrzeugschlüssel weist ein Betätigungselement auf, durch dessen Betätigung dieses erste Rastelement den Notschlüssel zur Entnahme freigibt.In this case, the emergency key is releasably locked in its rest position by a first locking element and the motor vehicle key has an actuating element, by the operation of this first locking element releases the emergency key for removal.

Nachteilig ist dabei, dass nach einer gegebenenfalls versehentlichen Betätigung der Notschlüssel von diesem ersten Rastelement freigegeben wird und versehentlich aus dem Gehäuse herausfallen und hierdurch verloren gehen kann. Weiterhin nachteilig ist, dass dann, wenn der Notschlüssel in Entnahmerichtung federbelastet ist, es passieren kann, dass bei einer Betätigung des Betätigungselementes der Notschlüssel aus dem Gehäuse durch die Feder herausgedrückt wird, was wiederum selbst in dem Fall, dass die Betätigung von dem Benutzer absichtlich ausgelöst wird, dazu führen kann, dass der Notschlüssel herunterfällt und im schlimmsten Fall verloren geht.The disadvantage here is that is released after an accidental operation, if necessary, the emergency key of this first locking element and accidentally fall out of the case and thus can be lost. Another disadvantage is that when the emergency key is spring-loaded in the withdrawal direction, it may happen that upon actuation of the actuating element of the emergency key is pushed out of the housing by the spring, which in turn, even in the event that the operation of the user intentionally can cause the emergency key to fall off and in the worst case to be lost.

Die Aufgabe der Erfindung ist es daher, einen Kraftfahrzeugschlüssel der eingangs genannten Art derart weiterzubilden, dass einerseits eine Entnahme des Notschlüssels auf eine leichte Art und Weise für den Benutzer ermöglicht wird und es andererseits gewährleistet ist, dass der Notschlüssel auch bei einer versehentlichen Betätigung des Betätigungselementes nicht verloren geht.The object of the invention is therefore to develop a motor vehicle key of the type mentioned in such a way that on the one hand a removal of the emergency key is made possible in an easy way for the user and on the other hand it ensures that the emergency key even with an accidental actuation of the actuating element not lost.

Diese Aufgabe wird erfindungsgemäß durch einen Kraftfahrzeugschlüssel nach Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a motor vehicle key according to claim 1. Advantageous developments of the invention are specified in the subclaims.

Besonders vorteilhaft bei dem Kraftfahrzeugschlüssel mit einem Identifikationsgeber zur Betätigung einer Kraftfahrzeugschließanlage über eine Luftschnittstelle, mit einem Gehäuse und einem in einer Ruheposition in dem Gehäuse angeordneten und entnehmbaren Notschlüssel zur mechanischen Betätigung der Kraftfahrzeugschließanlage, wobei der Notschlüssel in seiner Ruheposition von einem ersten Rastelement freigebbar verrastet wird und wobei der Kraftfahrzeugschlüssel eine Freigabetaste aufweist, durch deren Betätigung das erste Rastelement den Notschlüssel freigibt, ist es, dass der Kraftfahrzeugschlüssel ein zweites Rastelement als Zwischenraste aufweist, welches den Notschlüssel nach Freigabe durch das erste Rastelement und dem Verlassen seiner Ruheposition in einer Zwischenposition zwischen der Ruheposition und einer die Entnahme des Notschlüssels ermöglichenden Freigabeposition freigebbar verrastet.Particularly advantageous in the motor vehicle key with an identification transmitter for actuating a motor vehicle locking system via an air interface, with a housing and a arranged in a rest position in the housing and removable emergency key for mechanical actuation of the motor vehicle locking system, the emergency key is releasably locked in its rest position by a first locking element and wherein the motor vehicle key has a release button, by the actuation of the first locking element releases the emergency key, it is that the motor vehicle key has a second latching element as an intermediate catch, which the emergency key after release by the first locking element and leaving its rest position in an intermediate position between the Rest position and a release of the emergency key enabling release position releasably latched.

Kern der Erfindung ist es somit, dass zusätzlich zu dem ersten Rastelement, welches dazu vorgesehen ist den Notschlüssel in seiner Ruheposition innerhalb des Gehäuses des Kraftfahrzeugschlüssels freigebbar zu verrasten, ferner ein zweites Rastelement als Zwischenraste angeordnet ist. Diese Zwischenraste ist derart positioniert, dass der Notschlüssel nach der Betätigung der Freigabetaste und dem Verlassen seiner Ruheposition in einer Zwischenposition zwischen der Ruheposition und der Freigabeposition freigebbar verrastet wird. Zur endgültigen Freigabe des Notschlüssels ist es somit erforderlich, die Zwischenraste in Form des zweiten Rastelementes aus ihrer Raststellung, in welcher sie den Notschlüssel in der Zwischenposition freigebbar verrastet, zu verlagern, um hierdurch den Notschlüssel aus der Zwischenposition freizugeben und dessen Verlagerung in seine Freigabeposition zu ermöglichen, in welcher die Entnahme des Notschlüssels aus dem Gehäuse ermöglicht ist.The core of the invention is thus that, in addition to the first locking element, which is intended to releasably lock the emergency key in its rest position within the housing of the motor vehicle key, also a second locking element is arranged as an intermediate catch. This intermediate catch is positioned so that the emergency key is releasably latched after actuation of the release button and leaving its rest position in an intermediate position between the rest position and the release position. For final release of the emergency key, it is thus necessary, the intermediate catch in the form of the second locking element from its locking position in which it releasably locked the emergency key in the intermediate position, to thereby release the emergency key from the intermediate position and its displacement in its release position allow in which the removal of the emergency key is made possible from the housing.

Durch diese Zwischenraste wird ein versehentliches Herausfallen des Notschlüssels aus dem Gehäuse zuverlässig verhindert, unabhängig von der Frage, ob die Betätigung der Freigabetaste durch einen Benutzer bewusst oder versehentlich erfolgt. Hierdurch wird ein Verlust des Notschlüssels zuverlässig verhindert und die Entnahme für den Benutzer vereinfacht.By this intermediate catch accidental dropping out of the emergency key from the housing is reliably prevented, regardless of the question of whether the actuation of the release button by a user is aware or accidental. This reliably prevents a loss of the emergency key and simplifies removal for the user.

Das Gehäuse des Kraftfahrzeugschlüssels weist vorzugsweise einen Aufnahmeschacht auf, in welchem der Notschlüssel entnehmbar angeordnet ist. In seiner Ruheposition ist der Notschlüssel vorzugsweise vollständig in dem Gehäuse des Kraftfahrzeugschlüssels aufgenommen.The housing of the motor vehicle key preferably has a receiving shaft in which the emergency key is removably arranged. In its rest position, the emergency key is preferably completely received in the housing of the motor vehicle key.

Vorzugsweise sind das erste Rastelement und das zweite Rastelement kinematisch gekoppelt und derart angeordnet, dass durch eine Betätigung der Freigabetaste, durch die das erste Rastelement in eine Freigabestellung verlagert wird, das zweite Rastelement in eine Raststellung verlagert wird.Preferably, the first detent element and the second detent element are kinematically coupled and arranged such that by an actuation of the release button, by which the first detent element is displaced into a release position, the second detent element is displaced into a detent position.

Durch eine derartige kinematische Kopplung des ersten Rastelementes und des zweiten Rastelementes ist es gewährleistet, dass bei einem Verlagern des ersten Rastelementes von seiner Rastposition in eine Freigabeposition durch Betätigung der Freigabetaste automatisch das zweite Rastelement in seine Raststellung verlagert wird wodurch die Sicherung des Notschlüssels in der Zwischenposition automatisch herbeigeführt wird.By such a kinematic coupling of the first locking element and the second locking element, it is ensured that upon a displacement of the first locking element from its locking position to a release position Actuation of the release button automatically the second locking element is displaced into its locking position whereby the backup of the emergency key is automatically brought about in the intermediate position.

Das erste und/oder das zweite Rastelement können mittels einer rotatorischen Bewegung und/oder mittels translatorischen Bewegung oder einer Kombination aus rotatorischer und translatorischer Bewegung zwischen der jeweiligen Freigabestellung und der jeweiligen Raststellung verlagerbar sein.The first and / or the second latching element can be displaced by means of a rotary movement and / or by means of a translatory movement or a combination of rotational and translational movement between the respective release position and the respective latching position.

Vorzugsweise weist der Notschlüssel eine erste Rastung auf, die In der Ruheposition des Notschlüssels mit dem ersten Rastelement zusammen wirkt und den Notschlüssel in der Ruheposition freigebbar verrastet.Preferably, the emergency key has a first detent, which interacts with the first detent element in the rest position of the emergency key and locks the emergency key releasably in the rest position.

Vorzugsweise weist der Notschlüssel eine zweite Rastung auf, die in der Zwischenposition des Notschlüssels mit dem zweiten Rastelement zusammenwirkt und den Notschlüssel in der Zwischenposition freigebbar verrastet.Preferably, the emergency key on a second detent, which cooperates in the intermediate position of the emergency key with the second locking element and releasably locked the emergency key in the intermediate position.

Bei dieser ersten Rastung und/oder der zweiten Rastung des Notschlüssels kann es sich um Vorsprünge an dem Notschlüssel handeln, die von entsprechenden Gegenstücken übergriffen werden. Alternativ kann es sich um Hinterschneidungen handeln, die entsprechend hintergriffen werden. Auch ist es möglich, dass es sich bei der ersten und/oder der zweiten Rastung um Nuten handelt, in die entsprechende Rastelemente eingreifen.This first detent and / or the second detent of the emergency key may be projections on the emergency key, which are overlapped by corresponding counterparts. Alternatively, they may be undercuts, which are underpinned accordingly. It is also possible that the first and / or the second latching means are grooves in which corresponding latching elements engage.

In einer besonders bevorzugten Ausführungsform sind das erste Rastelement und das zweite Rastelement und die Freigabetaste einstückig ausgeführt.In a particularly preferred embodiment, the first locking element and the second locking element and the release button are made in one piece.

Durch eine derartige einstückige Ausführung von erstem Rastelement, zweitem Rastelement und der Freigabetaste kann über die Betätigung der Freigabetaste die jeweils gewünschte Freigabe des ersten Rastelementes und/oder des zweiten Rastelementes durch den Bediener herbeigeführt werden.By such a one-piece design of the first latching element, the second latching element and the release button, the respectively desired release of the first latching element and / or the second latching element can be brought about by the operator via the actuation of the release button.

Besonders bevorzugt ist das erste Rastelement in Richtung auf seine Rastposition federbelastet.Particularly preferably, the first latching element is spring-loaded in the direction of its latching position.

Durch eine derartige Federbelastung ist eine zuverlässige freigebbare Verrastung und Sicherung des Notschlüssels in seiner Ruheposition innerhalb des Kraftfahrzeugschlüsselgehäuses gewährleistet. Gleichzeitig bewirkt eine solche Federbelastung einen entsprechenden Gegendruck gegen eine Betätigung der Freigabetaste, die kinematisch mit zumindest dem ersten Rastelement gekoppelt ist.By such a spring load a reliable releasable locking and securing the emergency key is ensured in its rest position within the motor vehicle key housing. At the same time such a spring load causes a corresponding back pressure against actuation of the release button, which is kinematically coupled to at least the first latching element.

Ferner führt eine solche Federbelastung des erste Rastelementes in Richtung auf seiner Rastposition zu einem automatischen Einrasten dieses ersten Rastelementes nachdem vollständigen Einsetzen des Notschlüssels in die entsprechende Aufnahme in dem Gehäuse des Kraftfahrzeugschlüssels. In dem Fall, dass das erste Rastelement, das zweite Rastelement und die Freigabetaste einstückig ausgeführt sind führt eine solche Federbelastung zu einer Rückstellkraft in jene Richtung, in welcher das zweite Rastelement in seiner Freigabestellung und das erste Rastelement in seiner Raststellung ist Hierdurch wird ein in seine Ruheposition eingebrachter Notschlüssel wiederum automatisch verrastet und gegen ein Herausfallen gesichert.Furthermore, such spring loading of the first latching element in the direction of its latching position leads to an automatic latching of this first latching element after complete insertion of the emergency key into the corresponding receptacle in the housing of the motor vehicle key. In the event that the first locking element, the second locking element and the release button are made in one piece leads such a spring load to a restoring force in the direction in which the second locking element in its release position and the first locking element is in its rest position Rest position introduced emergency key again automatically locked and secured against falling out.

Vorzugsweise befindet sich der Notschlüssel in der Zwischenposition vollständig oder teilweise innerhalb des Gehäuses. Sofern die Zwischenposition derart angeordnet ist, dass sich der Notschlüssel innerhalb dieser Zwischenposition immer noch vollständig innerhalb des Gehäuses befindet, ist gewährleistet, dass keine überstehenden Kanten entstehen, sofern eine versehentliche Betätigung der Freigabetaste und ein Lösen des ersten Rastelementes erfolgt ist. Bei einem Lösen des zweiten Rastelementes und damit einer Freigabe des Notschlüssels aus der Zwischenposition kann dieser dann weiter in Richtung auf seine Freigabeposition verlagert werden, so dass der Notschlüssel entnehmbar ist.Preferably, the emergency key is in the intermediate position completely or partially within the housing. If the intermediate position is arranged such that the emergency key within this intermediate position is still completely within the housing, it is ensured that no protruding edges arise, provided that an accidental actuation of the release button and release of the first locking element has occurred. Upon release of the second latching element and thus a release of the emergency key from the intermediate position, this can then be moved further in the direction of its release position, so that the emergency key can be removed.

Auf der gegenüberliegenden Seite einstückig mit dem ersten Rastelement 5 ausgebildet ist ein zweites Rastelement 7 angeordnet, welches durch die Betätigung der Freigabetaste 3 aus seiner Ruheposition gemäß Fig. 3a in die Position gemäß Fig. 3b verlagert wird, in welcher der Notschlüssel 2 durch Lösen des ersten Rastelementes 5 freigegeben wird. Der Notschlüssel 2 weist eine zweite Rastung 8 auf, die bei einer Verlagerung des Notschlüssels von der Ruheposition in eine Zwischenposition gemäß Fig. 3c mit dem zweiten Rastelement 7, welches als Zwischenraste dient, in Eignriff kommt und den Notschlüssel 2 in der Zwischenposition gemäß Fig. 3c freigebbar verrastet. Die zweite Rastung 8 ist dementsprechend gegenüber der ersten Rastung 6 entlang der Länge des Notschlüssels versetzt angeordnet, da das erste Rastelement 5 und das zweite Rastelement 7 auf der gleichen Höhe senkrecht zur Bewegungsrichtung des Notschlüssels angeordnet sind. Solange die Freigabetaste 3 entsprechend Fig. 3c gegen die Federkraft der Feder 4 eingedrückt ist, bleibt das als Zwischen raste dienende zweite Rastelement 7 mit der zweiten Rastung 8 des Notschlüssels 2 im Eingriff und sichert den Notschlüssel 2 in der Zwischenposition.On the opposite side formed integrally with the first locking element 5, a second locking element 7 is arranged, which in accordance with the actuation of the release button 3 from its rest position Fig. 3a in the position according to Fig. 3b is shifted, in which the emergency key 2 is released by releasing the first locking element 5. The emergency key 2 has a second detent 8, which in a shift of the emergency key from the rest position to an intermediate position according to Fig. 3c with the second locking element 7, which serves as an intermediate catch comes into action and the emergency key 2 in the intermediate position according to Fig. 3c releasably latched. The second detent 8 is accordingly arranged offset relative to the first detent 6 along the length of the emergency key, since the first detent element 5 and the second detent element 7 are arranged at the same height perpendicular to the direction of movement of the emergency key. As long as the release button 3 accordingly Fig. 3c is pressed against the spring force of the spring 4, which serves as an intermediate detent second locking element 7 with the second detent 8 of the emergency key 2 remains engaged and secures the emergency key 2 in the intermediate position.

Zur Freigabe des Notschlüssels und um die Entnahme des Notschlüssels 2 aus dem Gehäuse 1 zu ermöglichen muss die Freigabetaste 3 wiederum losgelassen werden, wie dies in Fig. 3d dargestellt ist, so dass das zweite Rastelement 7 mit der zweiten Rastung 8 am Notschlüssel 2 außer Eingriff kommt und den Notschlüssel 2 zur Entnahme aus dem Gehäuse 1 freigibt. Solange die Freigabetaste 3 jedoch wie in Fig. 3c dargestellt gedrückt bleibt, ist eine Entnahme und damit ein Herausfallen des Notschlüssels 2 aus dem Gehäuse 1 nicht möglich. Hierdurch wird ein versehentliches Herausrutschen des Notschlüssels 2 aus dem Gehäuse 1 und damit ein Verlust des Notschlüssels 2 wirksam verhindert.To release the emergency key and to allow the removal of the emergency key 2 from the housing 1, the release button 3 must be released again, as in Fig. 3d is shown, so that the second locking element 7 with the second detent 8 on the emergency key 2 is disengaged and releases the emergency key 2 for removal from the housing 1. As long as the release button 3, however, as in Fig. 3c shown pressed, a removal and thus falling out of the emergency key 2 from the housing 1 is not possible. As a result, an accidental slipping out of the emergency key 2 from the housing 1 and thus a loss of the emergency key 2 is effectively prevented.

Der als erstes Rastelement 5 ausgebildete Rasthaken weist eine Anlaufschräge 10 auf, welche das Einschieben des Notschlüssels 2 in den entsprechenden Aufnahmeschacht innerhalb des Gehäuses 1 erleichtert. Das heißt, dass der Notschlüssel 2 nach einem Benutzen auf leichte Weise wieder in das Gehäuse 1 eingesetzt werden kann und in seiner Ruheposition gemäß Fig. 3a mit dem ersten Rastelement 5 in seiner Ruheposition freigebbar verrastet wird. Aufgrund der Rückstellkraft der Feder 4 erfolgt das Verrasten des Notschlüssels 2 in der Ruheposition innerhalb des Gehäuses 1 automatisch.The catch hook formed as a first latching element 5 has a run-on slope 10, which facilitates the insertion of the emergency key 2 into the corresponding receiving shaft within the housing 1. That is, the emergency key 2 can be easily re-inserted into the housing 1 after use, and in its rest position according to FIG Fig. 3a is releasably latched with the first locking element 5 in its rest position. Due to the restoring force of the spring 4, the latching of the emergency key 2 takes place automatically in the rest position within the housing 1.
