  • the present invention relates to a motor vehicle lock according to the preamble of claim 1 and a motor vehicle lock arrangement with such a motor vehicle lock according to claim 12.
  • the motor vehicle lock in question can be used for all types of locking elements of a motor vehicle. These include, in particular, side doors, rear doors, tailgates, trunk lids, front hoods, in particular engine hoods. These closure elements can basically be designed in the manner of sliding doors.
  • the well-known motor vehicle lock ( DE 10 2014 119 382 A1 ), from which the invention is based, provides three motor comfort functions.
  • the motor vehicle lock is equipped with the usual "lock latch" and "pawl” locking elements.
  • the first convenience function is a motorized opening function with which the pawl can be lifted out to open the locking element.
  • the second convenience function is a motorized opening function with which the lock latch and thus the locking element can be set up in the respective opening direction.
  • the third convenience function is a motorized closing function in which the lock latch and thus the locking element are pulled from a pre-locking position to a main locking position.
  • Another motor vehicle lock with a bidirectional drive arrangement for the three convenience functions is from the DE 197 00 887 A1 known.
  • the invention is based on the problem of designing and developing the known motor vehicle lock in such a way that its structural design is simplified with a high degree of compactness.
  • the motor vehicle lock has an actuation arrangement, the actuation of which can generate a closing movement and an opening movement of the lock latch and an opening movement of the pawl.
  • the actuation arrangement is assigned two actuation elements which are to be actuated in an actuation direction permanently assigned to the respective actuation element in order to implement the above comfort functions.
  • the term "permanently assigned actuation direction" means that the actuation of the respective actuation element is only provided in one and the same actuation direction.
  • the actuating element is a pivotable actuating element
  • the actuating direction defines one of the two pivoting directions of the actuating element.
  • the actuation of the actuating element is an adjustment of the actuating element from an initial position in the associated actuating direction, the return of the actuating element counter to the actuating direction is no longer assigned to the initial position of actuation. This reset is then preferably provided by a spring.
  • the proposed motor vehicle lock is particularly suitable for the use of a drive arrangement that is coupled to the actuating elements via Bowden cables that only transmit pulling movements.
  • the actuation arrangement have a first actuation element with a permanently assigned actuation direction and a second actuation element, which can be actuated separately therefrom, with a permanently assigned actuation direction, the closing movement and the opening movement of the lock latch depending on the actuation of the two actuation elements in the respectively assigned actuation direction and the opening movement of the pawl can be generated.
  • the term “separately actuatable” means in the present case that the two actuation elements can be actuated independently of one another, insofar as the motor vehicle lock otherwise permits this. This means in particular that one of the actuating elements can be actuated while the other actuating element remains unactuated.
  • the above, unidirectional actuation of the actuating elements alone results in a simplified structural design.
  • the actuating elements can be actuated independently of one another, which results in a high degree of flexibility with regard to the positioning of the actuating elements in the motor vehicle lock within certain limits. This in turn is a prerequisite for increasing the compactness of the motor vehicle lock.
  • the preferred embodiment according to claim 3 relates to the realization of two drive trains, which are designed separately from one another at least in sections, for generating the opening movement and the erecting movement on the one hand and the closing movement on the other.
  • Drive train means any mechanical structure via which drive movements can be transmitted. With “designed separately” is meant that the two drive trains can be operated independently of one another at least in sections, as far as the motor vehicle lock otherwise permits.
  • the above division of the comfort functions over two drive trains is particularly advantageous for various reasons. First of all, it is regularly the case that comparatively low forces are required for the opening movement and the erecting movement, while comparatively high forces are required for the closing movement. This results from the fact that the closing movement is regularly accompanied by a compression of door seals. With the proposed division, the drive trains can be designed differently accordingly.
  • the above distribution of the comfort functions between the two drive trains is also advantageous insofar as the set-up movement can, according to law, only take place after the opening movement.
  • This principle makes the generation of the opening movement and the erecting movement in a separate drive train appear particularly appropriate from a structural point of view.
  • the further preferred configurations according to claims 4 to 10 relate to advantageous design variants for the two drive trains.
  • the equipment of the first drive train with an opening element and a positioning element and the equipment of the second drive train with a closing element which each serve to initiate the relevant movements in the pawl and the lock latch.

  • the separate design of the two drive trains can hereby be implemented in a very simple way.
  • the proposed solution is particularly suitable for the actuation of the two actuating elements via two Bowden cables which exclusively transmit pulling movements and which are connected to a drive arrangement. Accordingly, it is preferably provided according to claim 11 that the motor vehicle lock with corresponding Bowden cable connections Is provided.
  • the use of Bowden cables represents a mechanically particularly robust and at the same time cost-effective way of transmitting cable movements.
  • the drive arrangement has a first Bowden cable, which is coupled to the first actuating element, and a second Bowden cable, which is coupled to the second actuating element.
  • alternating pulling movements can be introduced into the Bowden cables by means of the drive arrangement for actuating the actuating elements.

Description

Die vorliegende Erfindung betrifft ein Kraftfahrzeugschloss gemäß dem Oberbegriff von Anspruch 1 sowie eine Kraftfahrzeugschlossanordnung mit einem solchen Kraftfahrzeugschloss gemäß Anspruch 12.The present invention relates to a motor vehicle lock according to the preamble of claim 1 and a motor vehicle lock arrangement with such a motor vehicle lock according to claim 12.

Das in Rede stehende Kraftfahrzeugschloss kann bei allen Arten von Verschlusselementen eines Kraftfahrzeugs Anwendung finden. Dazu gehören insbesondere Seitentüren, Hecktüren, Heckklappen, Heckdeckel, Fronthauben, insbesondere Motorhauben. Diese Verschlusselemente können grundsätzlich nach Art von Schiebetüren ausgestaltet sein.The motor vehicle lock in question can be used for all types of locking elements of a motor vehicle. These include, in particular, side doors, rear doors, tailgates, trunk lids, front hoods, in particular engine hoods. These closure elements can basically be designed in the manner of sliding doors.

Insbesondere bei Seitentüren kommt dem komfortablen Öffnen und Schließen besondere Bedeutung zu. Vor diesem Hintergrund sind motorische Komfortfunktionen bekannt geworden, die der Unterstützung des Benutzers beim Öffnen und Schließen der Kraftfahrzeugtür dienen.Convenient opening and closing is particularly important for side doors. Against this background, motorized convenience functions have become known which serve to support the user when opening and closing the motor vehicle door.

Das bekannte Kraftfahrzeugschloss ( DE 10 2014 119 382 A1 ), von dem die Erfindung ausgeht, stellt drei motorische Komfortfunktionen bereit. Das Kraftfahrzeugschloss ist mit den üblichen Schließelementen "Schlossfalle" und "Sperrklinke" ausgestattet. Bei der ersten Komfortfunktion handelt es sich um eine motorische Öffnungsfunktion, mit der sich die Sperrklinke zum Öffnen des Verschlusselements ausheben lässt. Bei der zweiten Komfortfunktion handelt es sich um eine motorische Aufstellfunktion, mit der sich die Schlossfalle und damit das Verschlusselement in der jeweiligen Öffnungsrichtung aufstellen lässt. Bei der dritten Komfortfunktion handelt es sich um eine motorische Zuziehfunktion, bei der die Schlossfalle und damit das Verschlusselement von einer Vorschließstellung in eine Hauptschließstellung zugezogen werden.The well-known motor vehicle lock ( DE 10 2014 119 382 A1 ), from which the invention is based, provides three motor comfort functions. The motor vehicle lock is equipped with the usual "lock latch" and "pawl" locking elements. The first convenience function is a motorized opening function with which the pawl can be lifted out to open the locking element. The second convenience function is a motorized opening function with which the lock latch and thus the locking element can be set up in the respective opening direction. The third convenience function is a motorized closing function in which the lock latch and thus the locking element are pulled from a pre-locking position to a main locking position.

Alle drei Komfortfunktionen werden bei dem bekannten Kraftfahrzeugschloss von einer einzigen Antriebsanordnung übernommen, die separat vom Kraftfahrzeugschloss angeordnet sein kann und die über einen Bowdenzug mit dem Kraftfahrzeugschloss antriebstechnisch gekoppelt sein kann. Allerdings ist der konstruktive Aufbau wenig kompakt und vergleichsweise aufwändig. Dies geht in erster Linie auf die Tatsache zurück, dass die Schlossfalle für die Zuziehfunktion einerseits und die Aufstellfunktion andererseits in entgegengesetzten Richtungen anzutreiben ist, so dass der hieran beteiligte Antriebsstrang entsprechend bidirektional betrieben werden muss. Ähnliches gilt für ein ebenfalls bekanntes Kraftfahrzeugschloss ( DE 10 2014 205 371 A1 ), das einen alternativen konstruktiven Aufbau zeigt.In the known motor vehicle lock, all three comfort functions are taken over by a single drive arrangement which can be arranged separately from the motor vehicle lock and which can be drive-connected to the motor vehicle lock via a Bowden cable. However, the structural design is not very compact and comparatively complex. This is primarily due to the fact that the lock latch for the closing function on the one hand and the opening function on the other hand are in opposite directions Directions is to be driven, so that the drive train involved must be operated bidirectionally accordingly. The same applies to a well-known motor vehicle lock ( DE 10 2014 205 371 A1 ), which shows an alternative structural design.

Ein weiteres Kraftfahrzeugschloss mit bidirektionaler Antriebsanordnung für die drei Komfortfunktionen ist aus der DE 197 00 887 A1 bekannt.Another motor vehicle lock with a bidirectional drive arrangement for the three convenience functions is from the DE 197 00 887 A1 known.

Der Erfindung liegt das Problem zugrunde, das bekannte Kraftfahrzeugschloss derart auszugestalten und weiterzubilden, dass dessen konstruktiver Aufbau bei hoher Kompaktheit vereinfacht wird.The invention is based on the problem of designing and developing the known motor vehicle lock in such a way that its structural design is simplified with a high degree of compactness.

Das obige Problem wird bei einem Kraftfahrzeugschloss gemäß dem Oberbegriff von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The above problem is solved in a motor vehicle lock according to the preamble of claim 1 by the features of the characterizing part of claim 1.

Vorschlagsgemäß wird zunächst einmal davon ausgegangen, dass das Kraftfahrzeugschloss eine Betätigungsanordnung aufweist, durch deren Betätigung eine Zuziehbewegung und eine Aufstellbewegung der Schlossfalle sowie eine Öffnungsbewegung der Sperrklinke erzeugbar ist.According to the proposal, it is initially assumed that the motor vehicle lock has an actuation arrangement, the actuation of which can generate a closing movement and an opening movement of the lock latch and an opening movement of the pawl.

Wesentlich ist nun die grundsätzliche Erkenntnis, dass ein spezieller struktureller Aufbau der Betätigungsanordnung zu einer Vereinfachung nicht nur des Kraftfahrzeugschlosses, sondern auch der dem Kraftfahrzeugschloss zugeordneten Antriebsanordnung, also der Kraftfahrzeugschlossanordnung insgesamt, führt. Dabei werden der Betätigungsanordnung zwei Betätigungselemente zugeordnet, die in einer dem jeweiligen Betätigungselement fest zugeordneten Betätigungsrichtung zu betätigen sind, um die obigen Komfortfunktionen umzusetzen.The fundamental knowledge that a special structural design of the actuating arrangement leads to a simplification not only of the motor vehicle lock but also of the drive arrangement assigned to the motor vehicle lock, that is to say the motor vehicle lock arrangement as a whole, is now essential. In this case, the actuation arrangement is assigned two actuation elements which are to be actuated in an actuation direction permanently assigned to the respective actuation element in order to implement the above comfort functions.

Der Begriff "fest zugeordnete Betätigungsrichtung" bedeutet, dass die Betätigung des jeweiligen Betätigungselements nur in ein und derselben Betätigungsrichtung vorgesehen ist. Für den bevorzugten Fall, dass es sich bei dem Betätigungselement um ein schwenkbares Betätigungselement handelt, definiert die Betätigungsrichtung eine der beiden Schwenkrichtungen des Betätigungselements. Beispielsweise ist es vorzugsweise so, dass die Betätigung des Betätigungselements eine Verstellung des Betätigungselements aus einer Ausgangsstellung heraus in der zugeordneten Betätigungsrichtung ist, wobei die Rückstellung des Betätigungselements entgegen der Betätigungsrichtung zurück in die Ausgangsstellung der Betätigung nicht mehr zugeordnet ist. Diese Rückstellung ist dann vorzugsweise federgetrieben vorgesehen.The term "permanently assigned actuation direction" means that the actuation of the respective actuation element is only provided in one and the same actuation direction. For the preferred case that the actuating element is a pivotable actuating element, the actuating direction defines one of the two pivoting directions of the actuating element. For example, it is preferably such that the actuation of the actuating element is an adjustment of the actuating element from an initial position in the associated actuating direction, the return of the actuating element counter to the actuating direction is no longer assigned to the initial position of actuation. This reset is then preferably provided by a spring.

Dadurch, dass jedes Betätigungselement zur Umsetzung der in Rede stehenden Komfortfunktionen nur in der jeweiligen fest zugeordneten Betätigungsrichtung betätigt werden muss, eignet sich das vorschlagsgemäße Kraftfahrzeugschloss in besonderer Weise für die Verwendung einer Antriebsanordnung, die über ausschließlich Zugbewegungen übertragende Bowdenzüge mit den Betätigungselementen gekoppelt ist.Because each actuating element only has to be actuated in the respective permanently assigned actuating direction to implement the convenience functions in question, the proposed motor vehicle lock is particularly suitable for the use of a drive arrangement that is coupled to the actuating elements via Bowden cables that only transmit pulling movements.

Im Einzelnen wird vorgeschlagen, dass die Betätigungsanordnung ein erstes Betätigungselement mit einer fest zugeordneten Betätigungsrichtung und ein separat davon betätigbares, zweites Betätigungselement mit einer fest zugeordneten Betätigungsrichtung aufweist, wobei je nach Betätigung der beiden Betätigungselemente in der jeweils zugeordneten Betätigungsrichtung die Zuziehbewegung und die Aufstellbewegung der Schlossfalle sowie die Öffnungsbewegung der Sperrklinke erzeugbar sind. Der Begriff "separat betätigbar" bedeutet vorliegend, dass die beiden Betätigungselemente unabhängig voneinander betätigbar sind, soweit das Kraftfahrzeugschloss im Übrigen dies zulässt. Dies bedeutet insbesondere, dass eines der Betätigungselemente betätigbar ist, während das jeweils andere Betätigungselement unbetätigt bleibt.Specifically, it is proposed that the actuation arrangement have a first actuation element with a permanently assigned actuation direction and a second actuation element, which can be actuated separately therefrom, with a permanently assigned actuation direction, the closing movement and the opening movement of the lock latch depending on the actuation of the two actuation elements in the respectively assigned actuation direction and the opening movement of the pawl can be generated. The term “separately actuatable” means in the present case that the two actuation elements can be actuated independently of one another, insofar as the motor vehicle lock otherwise permits this. This means in particular that one of the actuating elements can be actuated while the other actuating element remains unactuated.

Mit der vorschlagsgemäßen Lösung ergibt sich allein durch die obige, unidirektionale Betätigung der Betätigungselemente ein vereinfachter konstruktiver Aufbau. Hinzu kommt, dass die Betätigungselemente unabhängig voneinander betätigbar sind, woraus sich in gewissen Grenzen eine hohe Flexibilität hinsichtlich der Positionierung der Betätigungselemente in dem Kraftfahrzeugschloss ergibt. Dies wiederum ist eine Voraussetzung für die Steigerung der Kompaktheit des Kraftfahrzeugschlosses.With the proposed solution, the above, unidirectional actuation of the actuating elements alone results in a simplified structural design. In addition, the actuating elements can be actuated independently of one another, which results in a high degree of flexibility with regard to the positioning of the actuating elements in the motor vehicle lock within certain limits. This in turn is a prerequisite for increasing the compactness of the motor vehicle lock.

Die bevorzugte Ausgestaltung gemäß Anspruch 3 betrifft die Realisierung zweier Antriebsstränge, die zumindest abschnittsweise separat voneinander ausgestaltet sind, für die Erzeugung der Öffnungsbewegung und der Aufstellbewegung einerseits und der Zuziehbewegung andererseits. Mit "Antriebsstrang" ist jede mechanische Struktur gemeint, über die Antriebsbewegungen übertragbar sind. Mit "separat ausgestaltet" ist gemeint, dass die beiden Antriebsstränge zumindest abschnittsweise unabhängig voneinander betätigbar sind, soweit dies das Kraftfahrzeugschloss im Übrigen zulässt.The preferred embodiment according to claim 3 relates to the realization of two drive trains, which are designed separately from one another at least in sections, for generating the opening movement and the erecting movement on the one hand and the closing movement on the other. "Drive train" means any mechanical structure via which drive movements can be transmitted. With "designed separately" is meant that the two drive trains can be operated independently of one another at least in sections, as far as the motor vehicle lock otherwise permits.

Die obige Aufteilung der Komfortfunktionen auf zwei Antriebsstränge, stellt sich aus verschiedenen Gründen besonders vorteilhaft dar. Zunächst einmal ist es regelmäßig so, dass für die Öffnungsbewegung und die Aufstellbewegung vergleichsweise geringe Kräfte erforderlich sind, während für die Zuziehbewegung vergleichsweise hohe Kräfte aufzubringen sind. Dies ergibt sich dadurch, dass die Zuziehbewegung regelmäßig mit einem Komprimieren von Türdichtungen einhergeht. Mit der vorschlagsgemäßen Aufteilung lassen sich die Antriebsstränge entsprechend unterschiedlich auslegen.The above division of the comfort functions over two drive trains is particularly advantageous for various reasons. First of all, it is regularly the case that comparatively low forces are required for the opening movement and the erecting movement, while comparatively high forces are required for the closing movement. This results from the fact that the closing movement is regularly accompanied by a compression of door seals. With the proposed division, the drive trains can be designed differently accordingly.

Die obige Aufteilung der Komfortfunktionen auf die beiden Antriebsstränge ist aber auch insoweit vorteilhaft, als die Aufstellbewegung denkgesetzlich erst im Anschluss an die Öffnungsbewegung stattfinden kann. Diese Gesetzmäßigkeit lässt die Erzeugung der Öffnungsbewegung und der Aufstellbewegung in einem separaten Antriebsstrang in konstruktiver Hinsicht als besonders sachgerecht erscheinen.The above distribution of the comfort functions between the two drive trains is also advantageous insofar as the set-up movement can, according to law, only take place after the opening movement. This principle makes the generation of the opening movement and the erecting movement in a separate drive train appear particularly appropriate from a structural point of view.

Die weiter bevorzugten Ausgestaltungen gemäß den Ansprüchen 4 bis 10 betreffen vorteilhafte Auslegungsvarianten für die beiden Antriebsstränge. Bemerkenswert sind hier die Ausstattung des ersten Antriebsstrangs mit einem Öffnungselement und einem Aufstellelement gemäß Anspruch 4 und die Ausstattung des zweiten Antriebsstrangs mit einem Zuziehelement, die jeweils der Einleitung der betreffenden Bewegungen in die Sperrklinke und die Schlossfalle dienen. Dabei ist es insbesondere vorgesehen, dass das Öffnungselement und das Aufstellelement einerseits und das Zuziehelement andererseits separat voneinander, also unabhängig voneinander ausgestaltet sind. Die voneinander separate Ausgestaltung der beiden Antriebsstränge lässt sich hierdurch auf denkbar einfache Weise umsetzen.The further preferred configurations according to claims 4 to 10 relate to advantageous design variants for the two drive trains. Noteworthy here are the equipment of the first drive train with an opening element and a positioning element and the equipment of the second drive train with a closing element, which each serve to initiate the relevant movements in the pawl and the lock latch. It is provided in particular that the opening element and the positioning element on the one hand and the closing element on the other hand are designed separately from one another, that is to say independently of one another. The separate design of the two drive trains can hereby be implemented in a very simple way.

Wie oben angedeutet, eignet sich die vorschlagsgemäße Lösung insbesondere für die Betätigung der beiden Betätigungselemente über zwei ausschließlich Zugbewegungen übertragende Bowdenzüge, die an eine Antriebsanordnung angeschlossen sind. Entsprechend ist es gemäß Anspruch 11 vorzugsweise vorgesehen, dass das Kraftfahrzeugschloss mit entsprechenden Bowdenzuganschlüssen ausgestattet ist. Die Anwendung von Bowdenzügen stellt hier eine mechanisch besonders robuste und gleichzeitig kostengünstige Art der Übertragung von Zugbewegungen dar.As indicated above, the proposed solution is particularly suitable for the actuation of the two actuating elements via two Bowden cables which exclusively transmit pulling movements and which are connected to a drive arrangement. Accordingly, it is preferably provided according to claim 11 that the motor vehicle lock with corresponding Bowden cable connections Is provided. The use of Bowden cables represents a mechanically particularly robust and at the same time cost-effective way of transmitting cable movements.

Nach einer weiteren Lehre gemäß Anspruch 12, der eigenständige Bedeutung zukommt, wird eine Kraftfahrzeugschlossanordnung mit einem vorschlagsgemäßen Kraftfahrzeugschloss sowie mit einer Antriebsanordnung als solche beansprucht.According to a further teaching according to claim 12, which is of independent significance, a motor vehicle lock arrangement with a proposed motor vehicle lock and with a drive arrangement as such is claimed.

Die Antriebsanordnung weist einen ersten Bowdenzug, der mit dem ersten Betätigungselement gekoppelt ist, und einen zweiten Bowdenzug, der mit dem zweiten Betätigungselement gekoppelt ist, auf. Vorschlagsgemäß sind mittels der Antriebsanordnung zur Betätigung der Betätigungselemente wechselweise Zugbewegungen in die Bowdenzüge einleitbar. Angesichts der oben angesprochenen, fest zugeordneten Betätigungsrichtungen der Betätigungselemente reichen solche Zugbewegungen aus, um die in Rede stehenden Komfortfunktionen umzusetzen.The drive arrangement has a first Bowden cable, which is coupled to the first actuating element, and a second Bowden cable, which is coupled to the second actuating element. According to the proposal, alternating pulling movements can be introduced into the Bowden cables by means of the drive arrangement for actuating the actuating elements. In view of the above-mentioned, permanently assigned actuation directions of the actuation elements, such pulling movements are sufficient to implement the convenience functions in question.

Gemäß Anspruch 13 kann die Antriebsanordnung mit einem Antriebsmotor oder mit mehr als einem Antriebsmotor ausgestattet sein. Bei den besonders bevorzugten Ausgestaltungen gemäß den Ansprüchen 14 und 15 ist ein einziger Antriebsmotor vorgesehen, der ein linear oder rotatorisch verstellbares Stellelement antreibt. Die Zugbewegungen in den beiden Bowdenzügen werden dadurch erzeugt, dass das Stellelement in zwei entgegengesetzten Antriebsrichtungen verstellbar ist. Bei der mechanisch besonders einfach zu realisierenden Variante gemäß Anspruch 15 ist hierfür eine Kupplungsanordnung vorgesehen, die für die beiden Bowdenzüge wechselweise als Freilaufkupplung arbeitet.According to claim 13, the drive arrangement can be equipped with one drive motor or with more than one drive motor. In the particularly preferred refinements according to claims 14 and 15, a single drive motor is provided which drives a linearly or rotationally adjustable adjusting element. The pulling movements in the two Bowden cables are generated in that the adjusting element can be adjusted in two opposite drive directions. In the variant according to claim 15, which is particularly easy to implement mechanically, a clutch arrangement is provided for this purpose, which operates alternately as a free-wheel clutch for the two Bowden cables.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. In der Zeichnung zeigt

Die vorschlagsgemäße Kraftfahrzeugschlossanordnung 1 weist ein Kraftfahrzeugschloss 2 und eine mit dem Kraftfahrzeugschloss 2 zusammenwirkende Antriebsanordnung 3 auf. Das Kraftfahrzeugschloss 2 kann jedwedem Verschlusselement 4 eines Kraftfahrzeugs zugeordnet sein. Hier und vorzugsweise handelt es sich bei dem Verschlusselement 4 um eine Seitentür eines Kraftfahrzeugs. Hinsichtlich weiterer möglicher Anwendungsbereiche darf auf den einleitenden Teil der Beschreibung verwiesen werden.The proposed motor vehicle lock arrangement 1 has a motor vehicle lock 2 and a drive arrangement 3 cooperating with the motor vehicle lock 2. The motor vehicle lock 2 can be assigned to any locking element 4 of a motor vehicle. Here, and preferably, the closure element 4 is a side door of a motor vehicle. With regard to other possible areas of application, reference may be made to the introductory part of the description.

Das in den Fig. 1 bis 4 dargestellte Kraftfahrzeugschloss 2 ist mit einer um eine Schlossfallenachse 5a schwenkbaren Schlossfalle 5 ausgestattet, die zwischen einer Offenstellung (Fig. 2a)), einer Vorschließstellung (Fig. 2b)) und einer Hauptschließstellung (Fig. 3b)) verstellbar ist. In den Schließstellungen wirkt die Schlossfalle 5 mit einem Schließteil 6 zusammen, bei dem es sich um einen Schließbügel, einen Schließbolzen oder dergleichen handeln kann. Die Schlossfalle 5 ist mittels einer Schlossfallenfeder 5b in Öffnungsrichtung vorgespannt.That in the Figs. 1 to 4 The motor vehicle lock 2 shown is equipped with a lock latch 5 which can be pivoted about a lock latch axis 5a and which moves between an open position ( Fig. 2a )), a pre-locking position ( Figure 2b )) and a main closed position ( Figure 3b )) is adjustable. In the closed positions, the latch 5 cooperates with a locking part 6, which can be a striker, a locking bolt or the like. The lock latch 5 is biased in the opening direction by means of a lock latch spring 5b.

Der Schlossfalle 5 ist eine um eine Sperrklinkenachse 7a schwenkbare Sperrklinke 7 zugeordnet, die in ihrer Einfallstellung die Schlossfalle 5 in der jeweiligen Schließstellung hält (Fig. 2b), 3b)). Hierfür kann die Sperrklinke 7, wie in der Zeichnung dargestellt, in unmittelbarem Eingriff mit der Schlossfalle 5 stehen. Denkbar ist aber auch, dass es sich bei der Sperrklinke 7 um eine sogenannte Sekundärsperrklinke handelt, die dem Sperren einer Primärsperrklinke dient. Dabei steht nicht die Sekundärsperrklinke, sondern die Primärsperrklinke in unmittelbarem Eingriff mit der Schlossfalle 5, so dass die Schlossfalle 5 von der Sperrklinke 7 nur mittelbar gesperrt wird. Andere Arten von Sperrklinken 7 können hier Anwendung finden.The lock latch 5 is assigned a locking pawl 7 which can pivot about a ratchet axis 7a and which, in its collapsed position, holds the lock latch 5 in the respective closed position ( Figure 2b ), 3b)). For this purpose, the pawl 7, as shown in the drawing, can be in direct engagement with the latch 5. It is also conceivable, however, that the pawl 7 is a so-called secondary pawl, which is used to lock a primary pawl serves. It is not the secondary pawl, but the primary pawl that is in direct engagement with the latch 5, so that the latch 5 is only indirectly blocked by the pawl 7. Other types of pawls 7 can be used here.

Die Sperrklinke 7 ist vorzugsweise mit einer Sperrklinkenfeder 7b ausgestattet, die die Sperrklinke 7 in ihre Einfallstellung vorspannt
Das vorschlagsgemäße Kraftfahrzeugschloss 2 weist eine Betätigungsanordnung 8 auf, durch deren Betätigung eine Zuziehbewegung 9 (Fig. 3a)) und eine Aufstellbewegung 10 (Fig. 4b)) der Schlossfalle 5 sowie eine Öffnungsbewegung 11 (Fig. 4a)) der Sperrklinke 7 erzeugbar ist.The pawl 7 is preferably equipped with a pawl spring 7b which biases the pawl 7 into its collapsed position
The proposed motor vehicle lock 2 has an actuation arrangement 8, through the actuation of which a closing movement 9 ( Fig. 3a )) and an erection movement 10 ( Figure 4b )) of the latch 5 and an opening movement 11 ( Figure 4a )) the pawl 7 can be generated.

Bei der Zuziehbewegung 9 handelt es sich vorzugsweise um eine Bewegung der Schlossfalle 5 von der Vorschließstellung in die Hauptschließstellung. Damit beschränkt sich das Schließen des Verschlusselements 4 für den Benutzer auf eine Verstellung der Schlossfalle 5 von der Offenstellung in die Vorschließstellung. Das anschließende Zuziehen des Verschlusselements 4 wird dann durch eine motorische Verstellung der Schlossfalle 5 von der Vorschließstellung in die Hauptschließstellung bewerkstelligt.The closing movement 9 is preferably a movement of the lock latch 5 from the pre-locking position into the main locking position. Thus, the closing of the closure element 4 for the user is limited to an adjustment of the latch 5 from the open position into the pre-closed position. The subsequent closing of the locking element 4 is then brought about by a motorized adjustment of the lock latch 5 from the pre-locking position into the main locking position.

Die Aufstellbewegung 10 der Schlossfalle 5 entspricht einer Verstellung der Schlossfalle 5 in Öffnungsrichtung je nach Auslegung bis zur Offenstellung oder über die Offenstellung hinaus. Damit wird dem Benutzer ein erster Abschnitt der Öffnungsbewegung des Verschlusselements 4 abgenommen. Ein solcher Aufstellvorgang kann beispielsweise vorgesehen sein, wenn das Verschlusselement 4 keinen Türaußengriff aufweist. Dann ergreift der Benutzer für das Öffnen des Verschlusselements 4 eben keinen Türaußengriff. Vielmehr hintergreift der Benutzer einen durch die Aufstellbewegung der Schlossfalle 5 erzeugten Eingriffsspalt zwischen Verschlusselement 4 und Kraftfahrzeugkarosserie. Grundsätzlich kann die Aufstellbewegung aber auch nur vorgesehen sein, um ein etwaiges Verkleben des Verschlusselements 4 an der Kraftfahrzeugkarosserie aufzuheben.The erecting movement 10 of the lock latch 5 corresponds to an adjustment of the lock latch 5 in the opening direction, depending on the design, up to the open position or beyond the open position. A first section of the opening movement of the closure element 4 is thus removed from the user. Such an erection process can be provided, for example, when the closure element 4 does not have an outside door handle. Then the user does not grasp an outside door handle to open the closure element 4. Rather, the user engages behind an engagement gap between the locking element 4 and the motor vehicle body that is created by the opening movement of the lock latch 5. In principle, however, the erecting movement can only be provided in order to prevent any sticking of the closure element 4 to the motor vehicle body.

Die Öffnungsbewegung 11 der Sperrklinke 7 dient dem motorischen Öffnen des Kraftfahrzeugschlosses 2, indem die Sperrklinke 7 die Schlossfalle 5 freigibt, wodurch das Schließteil 6 die Schlossfalle 5 verlassen kann und das Verschlusselement 4 frei vom Kraftfahrzeugschloss 2 verstellbar ist.The opening movement 11 of the pawl 7 is used to open the motor vehicle lock 2 by motor, in that the pawl 7 releases the latch 5, whereby the locking part 6 can leave the latch 5 and the locking element 4 is freely adjustable from the motor vehicle lock 2.

Wesentlich ist nun, dass die Betätigungsanordnung 8 ein erstes Betätigungselement 12 mit einer fest zugeordneten Betätigungsrichtung 13 und ein in obigem Sinne separat davon betätigbares, zweites Betätigungselement 14 mit einer ebenfalls fest zugeordneten Betätigungsrichtung 15 aufweist, wobei je nach Betätigung der beiden Betätigungselemente 12, 14 in der jeweils zugeordneten Betätigungsrichtung 13, 15 die Zuziehbewegung 9, die Aufstellbewegung 10 und die Öffnungsbewegung 11 erzeugbar sind.It is now essential that the actuation arrangement 8 has a first actuation element 12 with a permanently assigned actuation direction 13 and a second actuation element 14, which can be actuated separately in the above sense, with a likewise permanently assigned actuation direction 15, depending on the actuation of the two actuation elements 12, 14 in the respectively assigned actuation direction 13, 15, the closing movement 9, the erecting movement 10 and the opening movement 11 can be generated.

Die beiden Betätigungselemente 12, 14 sind jeweils um eine ortsfeste Betätigungselementachse 12a, 14a schwenkbar. Dabei ist es weiter vorzugsweise so, dass die Betätigungselementachse 12a des ersten Betätigungselements 12 beabstandet von der Schlossfallenachse 5a und der Sperrklinkenachse 7a ist. Alternativ oder zusätzlich ist es so, dass die Betätigungselementachse 14a des zweiten Betätigungselements 14 beabstandet von der Schlossfallenachse 5a und der Sperrklinkenachse 7a ist. Insbesondere die Beabstandung der Betätigungselementachse 12a des ersten Betätigungselements 12 von der Sperrklinkenachse 7a ist vorliegend für die Erzeugung der Öffnungsbewegung und der Aufstellbewegung von Bedeutung, wie noch erläutert wird.The two actuation elements 12, 14 are each pivotable about a stationary actuation element axis 12a, 14a. It is further preferred that the actuating element axis 12a of the first actuating element 12 is spaced apart from the lock latch axis 5a and the pawl axis 7a. Alternatively or additionally, the actuating element axis 14a of the second actuating element 14 is spaced apart from the lock latch axis 5a and the ratchet axis 7a. In particular, the spacing of the actuation element axis 12a of the first actuation element 12 from the pawl axis 7a is important in the present case for generating the opening movement and the erecting movement, as will be explained below.

Das erste Betätigungselement 12 ist hier Bestandteil eines ersten Antriebsstrangs 16, während das zweite Betätigungselement 14 Bestandteil eines zweiten Antriebsstrangs 17 ist, der zumindest abschnittsweise, hier und vorzugsweise vollständig, in obigem Sinne separat von dem ersten Antriebsstrang 16 ausgestaltet ist.The first actuating element 12 is here part of a first drive train 16, while the second actuating element 14 is part of a second drive train 17, which is at least partially, here and preferably completely, configured separately from the first drive train 16 in the above sense.

Interessant ist nun die Tatsache, dass der erste Antriebsstrang 16 zur Erzeugung der Öffnungsbewegung 11 auf die Sperrklinke 7 und zur Erzeugung der Aufstellbewegung 10 auf die Schlossfalle 5 wirkt, während der zweite Antriebsstrang 17 zur Erzeugung der Zuziehbewegung 9 auf die Schlossfalle 5 wirkt.It is interesting to note that the first drive train 16 acts on the pawl 7 to generate the opening movement 11 and on the latch 5 to generate the erecting movement 10, while the second drive train 17 acts on the latch 5 to generate the closing movement 9.

Der erste Antriebsstrang 16 weist bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel ein Öffnungselement 18 mit einer Öffnungs-Eingriffskontur 18a für die Einleitung der Öffnungsbewegung 11 in die Sperrklinke 7 und ein Aufstellelement 19 mit einer Aufstell-Eingriffskontur 19a für die Einleitung der Aufstellbewegung 10 in die Schlossfalle 5 auf. Dabei bilden weiter vorzugsweise das Öffnungselement 18 und das Aufstellelement 19 über ein Verbindungsgelenk 20 eine Gelenkkette. Wie der Darstellung in den Fig. 1 bis 4 zu entnehmen ist, stellt das erste Betätigungselement 12 zumindest einen Teil des Öffnungselements 18 bereit. Alternativ kann es auch lediglich vorgesehen sein, dass das erste Betätigungselement 12 mit dem Öffnungselement 18 verbunden ist.The first drive train 16 has in the illustrated and thus preferred exemplary embodiment an opening element 18 with an opening engagement contour 18a for initiating the opening movement 11 in the pawl 7 and a positioning element 19 with a positioning engagement contour 19a for initiating the positioning movement 10 in the lock latch 5. In this case, the opening element 18 and the positioning element 19 also preferably form a link chain via a connecting joint 20. As shown in the Figs. 1 to 4 As can be seen, the first actuating element 12 provides at least part of the opening element 18. Alternatively, it can also only be provided that the first actuating element 12 is connected to the opening element 18.

Durch die Schwenkbarkeit des ersten Betätigungselements 12 um die Betätigungselementachse 12a teilt sich der erste Antriebsstrang 16 hier gewissermaßen in zwei Teilantriebsstränge auf, die einerseits von dem Öffnungselement 18 und andererseits von dem Aufstellelement 19 bereitgestellt werden.Due to the pivotability of the first actuation element 12 about the actuation element axis 12a, the first drive train 16 is divided into two partial drive trains, which are provided by the opening element 18 on the one hand and by the positioning element 19 on the other.

Der erste Antriebsstrang 16 ist nun so ausgelegt, dass im Zuge einer Betätigung des ersten Betätigungselements 12 in der zugeordneten Betätigungsrichtung 13 zunächst die Öffnungs-Eingriffskontur 18a in Eingriff mit der Sperrklinke 7 kommt und die Sperrklinke 7 aushebt und erst anschließend die Ausstell-Eingriffskontur 19a in Eingriff mit der Schlossfalle 5 kommt und die Schlossfalle 5 aufstellt.The first drive train 16 is now designed in such a way that when the first actuating element 12 is actuated in the associated actuation direction 13, the opening engagement contour 18a first comes into engagement with the pawl 7 and lifts the pawl 7 and only then does the opening engagement contour 19a in Engagement with the latch 5 comes and the latch 5 sets up.

Im Einzelnen weist die Sperrklinke 7 vorzugsweise eine Öffnungs-Gegenkontur 21 auf, wobei die Öffnungs-Eingriffskontur 18a im Zuge einer Betätigung des ersten Betätigungselements 12 mit der Öffnungs-Gegenkontur 21 in Eingriff kommt. Bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel ist es vorgesehen, dass die Öffnungs-Eingriffskontur 18a im Zuge der Betätigung des ersten Betätigungselements 12 an der Öffnungs-Gegenkontur 21 entlanggleitet. Mit diesem Eingriff zwischen der Öffnungs-Eingriffskontur 18a und der Öffnungs-Gegenkontur 21 wird erreicht, dass die Sperrklinke 7 ausgehoben wird und während der Erzeugung der Aufstellbewegung 10 ausgehoben bleibt. Dies ist in der Zeichnung durch den Übergang von Fig. 3b) über Fig. 4a) auf Fig. 4b) gezeigt. Hierbei wird deutlich, dass der Eingriff des Öffnungselements 18 mit der Sperrklinke 7 genau auf den Eingriff des Aufstellelements 19 mit der Schlossfalle 5 abgestimmt sein muss. Diese Abstimmung lässt sich auf besonders einfache Weise durch eine entsprechende, weiter oben bereits angesprochene Beabstandung der Betätigungselementachse 12a des ersten Betätigungselements 12 von der Sperrklinkenachse 7a einstellen.In detail, the pawl 7 preferably has an opening mating contour 21, the opening engagement contour 18a engaging with the opening mating contour 21 in the course of actuation of the first actuating element 12. In the illustrated and insofar preferred exemplary embodiment, it is provided that the opening engagement contour 18a slides along the opening counter contour 21 in the course of the actuation of the first actuating element 12. With this engagement between the opening engagement contour 18a and the opening counter contour 21 it is achieved that the pawl 7 is lifted out and remains lifted during the generation of the erecting movement 10. This is shown in the drawing by the transition from Figure 3b ) about Figure 4a ) on Figure 4b ) shown. It becomes clear here that the engagement of the opening element 18 with the pawl 7 must be precisely coordinated with the engagement of the positioning element 19 with the latch 5. This coordination can be carried out in a particularly simple manner by means of a corresponding one that has already been addressed above Set the spacing of the actuating element axis 12a of the first actuating element 12 from the pawl axis 7a.

Ähnlich wie die Sperrklinke 7 weist auch die Schlossfalle 5 eine Gegenkontur, nämlich eine Aufstell-Gegenkontur 22 auf, mit der die Aufstell-Eingriffskontur 19a während der Aufstellbewegung 10 in Eingriff kommt. Die Aufstell-Gegenkontur 22 befindet sich am Außenumfang der im Wesentlichen scheibenartigen Schlossfalle 5.Similar to the pawl 7, the latch 5 also has a counter-contour, namely a set-up counter-contour 22, with which the set-up engagement contour 19a comes into engagement during the set-up movement 10. The opposing set-up contour 22 is located on the outer circumference of the essentially disk-like lock latch 5.

Fig. 3a) zeigt, dass der zweite Antriebsstrang 17 ein Zuziehelement 23 mit einer Zuzieh-Eingriffskontur 23a für die Einleitung der Zuziehbewegung 9 in die Schlossfalle 5 aufweist. Hierfür ist die Schlossfalle 5 mit einer Zuzieh-Gegenkontur 24 ausgestattet, wobei im Zuge der Betätigung des zweiten Betätigungselements 14 die Zuzieh-Eingriffskontur 23a mit der Zuzieh-Gegenkontur 24 in Eingriff kommt und die Zuziehbewegung in die Schlossfalle 5 einleitet. Dies entspricht dem Übergang von Fig. 2b) auf Fig. 3a). Fig. 3a ) shows that the second drive train 17 has a closing element 23 with a closing engagement contour 23a for initiating the closing movement 9 into the lock latch 5. For this purpose, the lock latch 5 is equipped with a closing mating contour 24, with the closing engagement contour 23a engaging with the closing mating contour 24 as the second actuating element 14 is actuated and initiating the closing movement into the lock latch 5. This corresponds to the transition from Figure 2b ) on Fig. 3a ).

Im Sinne der oben angesprochenen, separaten Ausgestaltung der Antriebsstränge 16, 17 ist es nun vorgesehen, dass im Zuge der Betätigung des ersten Betätigungselements 12 die Zuzieh-Eingriffskontur 23a außerhalb des Bewegungsbereichs der Zuzieh-Gegenkontur 24 steht, wie den Darstellungen gemäß Fig. 4a) und Fig. 4b) zu entnehmen ist.In terms of the above-mentioned, separate configuration of the drive trains 16, 17, it is now provided that in the course of the actuation of the first actuating element 12, the closing engagement contour 23a is outside the range of motion of the closing countercontour 24, as shown in the illustrations Fig. 4a) and Fig. 4b ) can be found.

Wie oben im Zusammenhang mit dem ersten Betätigungselement 12 erläutert, ist es vorzugsweise vorgesehen, dass das zweite Betätigungselement 14 zumindest einen Teil des Zuziehelements 23 bereitstellt. Alternativ kann es auch hier vorgesehen sein, dass das zweite Betätigungselement 14 mit dem Zuziehelement 23 lediglich verbunden ist.As explained above in connection with the first actuating element 12, it is preferably provided that the second actuating element 14 provides at least part of the closing element 23. Alternatively, it can also be provided here that the second actuating element 14 is merely connected to the closing element 23.

Auf Grund der jeweils fest zugeordneten Betätigungsrichtungen 13, 15 lässt sich die Betätigungsanordnung 8 ohne Weiteres durch solche Bowdenzüge 25, 26 betätigen, die ausschließlich Zugbewegungen übertragen. Ein bidirektional übertragender Bowdenzug, beispielsweise ein Push-Pull-Bowdenzug, ist angesichts der vorschlagsgemäßen Struktur der Betätigungsanordnung 8 nicht erforderlich. Damit ergibt sich eine besonders kostengünstige Auslegung der Bowdenzüge 25, 26.On the basis of the respectively permanently assigned actuation directions 13, 15, the actuation arrangement 8 can be actuated easily by such Bowden cables 25, 26 which only transmit pulling movements. A bidirectionally transmitting Bowden cable, for example a push-pull Bowden cable, is not necessary in view of the proposed structure of the actuating arrangement 8. This results in a particularly cost-effective design of the Bowden cables 25, 26.

Vorzugsweise ist das Kraftfahrzeugschloss 2 mit einem ersten Bowdenzuganschluss 27 und mit einem zweiten Bowdenzuganschluss 28 ausgestattet, wobei den beiden Betätigungselementen 12, 14 jeweils ein Bowdenzuganschluss 27, 28 für den bewegungseinleitenden Anschluss eines Bowdenzugs 25, 26 zugeordnet sind. Anderenends sind die Bowdenzüge 25, 26 mit einer Antriebsanordnung 3 gekoppelt, wie im Zusammenhang mit der zweiten Lehre nun im Detail erläutert wird.The motor vehicle lock 2 is preferably equipped with a first Bowden cable connection 27 and with a second Bowden cable connection 28, the two actuating elements 12, 14 each being assigned a Bowden cable connection 27, 28 for the movement-initiating connection of a Bowden cable 25, 26. At the other end, the Bowden cables 25, 26 are coupled to a drive arrangement 3, as will now be explained in detail in connection with the second teaching.

Gemäß der zweiten Lehre wird die Kraftfahrzeugschlossanordnung 1 als solche beansprucht, die ein vorschlagsgemäßes Kraftfahrzeugschloss 2 und eine obige Antriebsanordnung 3 aufweist. Die Antriebsanordnung 3 weist einen ersten Bowdenzug 25, der mit dem ersten Betätigungselement 12 gekoppelt ist, und einen zweiten Bowdenzug 26, der mit dem zweiten Betätigungselement 14 gekoppelt ist, auf. Dabei sind mittels der Antriebsanordnung 3 zur Betätigung der Betätigungselemente 12, 14 wechselweise Zugbewegungen in die Bowdenzüge 25, 26, insbesondere in die Seelen 25a, 26a der Bowdenzüge 25, 26, einleitbar.According to the second teaching, the motor vehicle lock arrangement 1 is claimed as having a motor vehicle lock 2 according to the proposal and an above drive arrangement 3. The drive arrangement 3 has a first Bowden cable 25, which is coupled to the first actuating element 12, and a second Bowden cable 26, which is coupled to the second actuating element 14. In this case, by means of the drive arrangement 3 for actuating the actuating elements 12, 14, alternating pulling movements can be introduced into the Bowden cables 25, 26, in particular into the cores 25a, 26a of the Bowden cables 25, 26.

Die Darstellung gemäß Fig. 5 zeigt, dass die Antriebsanordnung 3 in einem von dem Kraftfahrzeugschloss 2 separaten Antriebsgehäuse 29 mindestens einen Antriebsmotor 30, hier und vorzugsweise genau einen Antriebsmotor 30, zur Erzeugung der Zugbewegungen aufweist. Der Antriebsmotor 30 ist über ein Zwischengetriebe 31 mit einem rotatorisch verstellbaren Stellelement 32 gekoppelt. Je nach Anwendungsfall kann auf das Zwischengetriebe 31 auch verzichtet werden.The representation according to Fig. 5 shows that the drive arrangement 3 in a drive housing 29 separate from the motor vehicle lock 2 has at least one drive motor 30, here and preferably precisely one drive motor 30, for generating the pulling movements. The drive motor 30 is coupled via an intermediate gear 31 to a rotationally adjustable adjusting element 32. Depending on the application, the intermediate gear 31 can also be dispensed with.

Alternativ zu der rotatorischen Verstellbarkeit des Stellelements 32 kann auch eine lineare Verstellbarkeit des Stellelements 32 vorgesehen sein. Alle Ausführungen zu der rotatorischen Verstellbarkeit des Stellelements 32 gelten für eine eventuelle, lineare Verstellbarkeit des Stellelements 32 entsprechend.As an alternative to the rotational adjustability of the adjusting element 32, a linear adjustability of the adjusting element 32 can also be provided. All statements regarding the rotational adjustability of the adjusting element 32 apply accordingly to a possible linear adjustability of the adjusting element 32.

Das Stellelement 32 ist mittels des Antriebsmotors 30 in zwei entgegengesetzten Antriebsrichtungen, hier in zwei entgegengesetzten Schwenkrichtungen, verstellbar, wobei das Stellelement 32 über eine Kupplungsanordnung 33 mit den Bowdenzügen 25, 26, hier und vorzugsweise mit den antriebsseitigen Bowdenzugendstücken 25b, 26b, der Bowdenzüge 25, 26, gekoppelt ist. Bei den Bowdenzugendstücken 25b, 26b handelt es sich beispielsweise um tonnenförmige Bowdenzugendstücke, um kugelförmige Bowdenzugendstücke o.dgl.The actuating element 32 can be adjusted by means of the drive motor 30 in two opposite drive directions, here in two opposite pivoting directions, the actuating element 32 via a coupling arrangement 33 with the Bowden cables 25, 26, here and preferably with the drive-side Bowden cable end pieces 25b, 26b, the Bowden cables 25, 26, is coupled. The Bowden cable end pieces 25b, 26b are, for example, barrel-shaped Bowden cable end pieces, spherical Bowden cable end pieces or the like.

Die Kupplungsanordnung 33 ist hier und vorzugsweise in das Stellelement 32 integriert. Alternativ kann es auch vorgesehen sein, dass die Kupplungsanordnung 33 separat von dem Stellelement 32 ausgestaltet ist.The coupling arrangement 33 is here and preferably integrated into the actuating element 32. Alternatively, it can also be provided that the coupling arrangement 33 is configured separately from the actuating element 32.

Die Kupplungsanordnung 33 ist vorzugsweise derart ausgestaltet, dass in einer ersten Antriebsrichtung 34 des Stellelements 32 eine Zugbewegung in den ersten Bowdenzug 25 und in einer zweiten Antriebsrichtung 35 des Stellelements 32 eine Zugbewegung in den zweiten Bowdenzug 26 einleitbar ist. Dabei ist es vorzugsweise so, dass die Kupplungsanordnung 33 die antriebsseitigen Bowdenzugendstücke 25b, 26b der beiden Bowdenzüge 25, 26 je nach Antriebsrichtung des Stellelements 32 wechselweise mitnimmt oder freilaufen lässt. Hierfür weist das Stellelement 32 eine erste Mitnahmekontur 36 für den ersten Bowdenzug 25 und eine zweite Mitnahmekante 37 für den zweiten Bowdenzug 26 auf. Fig. 5 zeigt eine Ausgangsstellung für das Stellelement 32, aus der heraus eine Verstellung des Stellelements 32 in der ersten Antriebsrichtung 34 über die erste Mitnahmekontur 36 eine Zugbewegung in den ersten Bowdenzug 25 einleitet. Entsprechendes gilt für den zweiten Bowdenzug 26 bei einer Verstellung des Stellelements 32 in der zweiten Antriebsrichtung 35.The clutch arrangement 33 is preferably designed such that a pulling movement in the first Bowden cable 25 can be initiated in a first drive direction 34 of the actuating element 32 and a pulling movement in the second Bowden cable 26 can be initiated in a second drive direction 35 of the actuating element 32. It is preferably such that the coupling arrangement 33 alternately entrains the drive-side Bowden cable end pieces 25b, 26b of the two Bowden cables 25, 26 depending on the drive direction of the actuating element 32 or allows them to run freely. For this purpose, the adjusting element 32 has a first driving contour 36 for the first Bowden cable 25 and a second driving edge 37 for the second Bowden cable 26. Fig. 5 shows an initial position for the adjusting element 32, from which an adjustment of the adjusting element 32 in the first drive direction 34 via the first entrainment contour 36 initiates a pulling movement in the first Bowden cable 25. The same applies to the second Bowden cable 26 when the adjusting element 32 is adjusted in the second drive direction 35.

Die Kupplungsanordnung 33 weist neben den beiden Mitnahmekonturen 36, 37 einen ersten Freilaufabschnitt 38 und einen zweiten Freilaufabschnitt 39 auf, die von dem jeweils nicht mitgenommenen Bowdenzug 25, 26 durchlaufen werden. Damit ist gewährleistet, dass je nach Antriebsrichtung 34, 35 des Stellelements 32 eine Zugbewegung nur in einen der Bowdenzüge 25, 26 eingeleitet wird, während der jeweils andere Bowdenzug 26, 25 unbeeinflusst von dem Stellelement 32 bleibt.In addition to the two entrainment contours 36, 37, the clutch arrangement 33 has a first freewheel section 38 and a second freewheel section 39, which are traversed by the Bowden cable 25, 26 that is not entrained. This ensures that, depending on the drive direction 34, 35 of the actuating element 32, a pulling movement is only introduced into one of the Bowden cables 25, 26, while the other Bowden cable 26, 25 remains unaffected by the actuating element 32.

Mit der vorschlagsgemäßen Kraftfahrzeugschlossanordnung 1 lassen sich die Zuziehfunktion, die Aufstellfunktion und die Öffnungsfunktion mit einem mechanisch besonders einfach aufgebauten Kraftfahrzeugschloss 1 und mit einer mechanisch besonders einfach aufgebauten Antriebsanordnung 3 umsetzten, die über kostengünstige, ausschließlich Zugbewegungen übertragende Bowdenzüge 25, 26 miteinander gekoppelt sind. Diese Vorteile gehen auf die Aufteilung der Öffnungsfunktion und der Aufstellfunktion auf einen ersten Antriebsstrang 16 und der Zuziehfunktion auf einen zweiten Antriebsstrang 17 zurück. Dabei sind die beiden Antriebsstränge 16, 17 zumindest abschnittsweise separat voneinander ausgestaltet, so dass eine entsprechend voneinander unabhängige Auslegung der Antriebsstränge 16, 17 in konstruktiv einfacher und kompakt bauender Weise möglich ist.With the proposed motor vehicle lock arrangement 1, the closing function, the erecting function and the opening function can be implemented with a mechanically particularly simple motor vehicle lock 1 and with a mechanically particularly simply constructed drive arrangement 3 which are coupled to one another via inexpensive Bowden cables 25, 26 that transmit only pulling movements. These advantages are due to the division of the opening function and the positioning function on a first drive train 16 and the closing function on a second drive train 17. The two drive trains 16, 17 are configured separately from one another, at least in sections, so that a correspondingly independent design of the drive trains 16, 17 is possible in a structurally simple and compact manner.
