Definitions

  • the invention relates to a lock logic arrangement for a motor vehicle lock arrangement according to the preamble of claim 1 and a motor vehicle lock arrangement as such according to the preamble of claim 15.
  • motor vehicle lock arrangement encompasses all types of door, hood or flap lock arrangements.
  • the motor vehicle lock arrangement in question is equipped with a lock logic arrangement on the one hand and a locking mechanism on the other. While the lock logic arrangement is used to set different lock states such as “unlocked” and “locked”, the locking mechanism takes care of the holding forces that are required to hold the respective motor vehicle door or the like.
  • the well-known lock logic arrangement ( DE 20 2013 105 314 U1 ), from which the invention is based, is assigned to a motor vehicle lock arrangement which, in the assembled state, is coupled to at least one outside door handle.
  • the lock mechanism has a switching element designed as a central locking lever with which the lock states “unlocked” and “locked” can be set. In the “unlocked” lock state, the locking mechanism can be opened by mechanical actuation of the outside door handle, while in the "locked” lock state a mechanical actuation of the outside door handle is released or blocked.
  • the central locking lever is adjusted to its respective switching positions by an actuator that is coupled to the central locking lever via a push-push mechanism.
  • the push-push mechanism has an input lever, an intermediate lever mounted on the input lever and spring-preloaded into a central position, and the switching element designed as a central locking lever.
  • This push-push mechanism made up of three levers, is mechanically robust, but comparatively complex to manufacture.
  • the invention is based on the problem of designing and developing the known lock logic arrangement in such a way that the cost of its manufacture is reduced.
  • the ratchet function can be produced by the switching element itself, provided that a locking spring arrangement is assigned to the switching element.
  • the latching spring arrangement fixes the switching element in a latching manner in each of the switching positions.
  • the detent spring arrangement is tensioned by the input element in the course of a push movement of the input element and then over-locked.
  • the detent spring arrangement is only tensioned by the input element, but not over-locked.
  • the locking spring arrangement ensures that the switching element assumes a mechanically stable state of equilibrium in each of the switching positions. This means that the switching element is deflected out of the respective switching position against the spring force of the detent spring arrangement. After the latching spring arrangement has been over-latched, the latching spring arrangement establishes a mechanically stable state of equilibrium for the respective new switching position, so that the switching element, driven by the latching spring arrangement, falls into the new switching position after the latching.
  • the push movement causes the detent spring arrangement to latch and thus a spring-driven adjustment of the switching element into the new switching position and that a loading movement only causes the switching element to be deflected out of the respective switching position, but not latching so that after completion of the loading movement, the switching element, again driven by the locking spring arrangement, can fall back into its original switching position.
  • the push-push function can be implemented with the proposed solution from just two levers and a locking spring arrangement. An intermediate lever of any kind for realizing the ratchet function is no longer required.
  • the proposed lock logic arrangement is used for the implementation of a central locking function, in particular for the implementation of the lock states "unlocked” and "locked".
  • the high mechanical robustness of the proposed lock logic arrangement which is achievable not least because of the small number of parts, means that the proposed lock logic arrangement is particularly suitable for the central locking function that is most frequently used in a motor vehicle.
  • the further preferred embodiment according to claim 3 relates to the use of the detent spring arrangement for the implementation of a second part of the switching movement of the switching element in which the input element has already come out of driving engagement from the switching element.
  • the driving engagement between the input element and the switching element can be implemented in a structurally particularly simple manner.
  • a push movement always causes a switching movement in one and the same direction of movement.
  • the switching element is preferably designed to be endlessly rotatable. Different drive directions are therefore not required for the adjustment of the switching element, which further simplifies the structural design.
  • the proposed solution allows the actuator to be designed unidirectionally (claim 9).
  • a resetting spring according to claim 10 is provided, which acts against the drive direction of the input element.
  • An embodiment according to claims 9 and 10 can best be realized by a particularly preferred embodiment according to claim 11, in which the input element is driven via a flexible traction means, in particular a rope, a belt or a chain. This can be implemented not only in a simple manner in terms of production engineering, but also inexpensively.
  • the loading movement of the input element is driven by the drive motor of the actuator, while the push movement is driven by the return spring arrangement.
  • This enables, for example, a comparatively weak design of the drive motor, since the movement in the drive direction of the input element does not necessarily have to take place at high speed.
  • This is different in the case of the return movement, which here and preferably is the push movement, which must bring about the desired switching of the switching element as quickly as possible.
  • the further preferred refinements according to claims 13 and 14 relate to variants for a central locking clutch which is controlled by the switching element and which are easy to implement in terms of manufacturing technology and in particular have a compact design.
  • the proposed lock logic arrangement 1 is assigned to a motor vehicle lock arrangement 2.
  • motor vehicle lock arrangement With regard to the broad interpretation of the term “motor vehicle lock arrangement”, reference may be made to the introductory part of the description.
  • the motor vehicle lock arrangement 2 has, in addition to the lock logic arrangement 1, a locking mechanism 3, which here and preferably has the usual locking elements lock latch 4 and locking pawl 5.
  • the lock latch 4 can be converted into an in Fig. 1 Bring the illustrated closed position in which it is in holding engagement with a striker 6 or the like.
  • a striker a striker, a locking bolt or the like can also be used.
  • the pawl 5 holds the latch 4 in its closed position.
  • the pawl 5 can be adjusted into a raised position, not shown, in which it releases the lock latch 4 so that the associated motor vehicle door or the like can be opened.
  • the motor vehicle lock arrangement 2 is mechanically coupled to an outside door handle 7 and possibly to an inside door handle 8. This coupling is preferably done via a Bowden cable, a linkage or the like.
  • the lock logic arrangement 1 and the locking mechanism 3 are combined in one unit and, in particular, accommodated in a housing 9. In principle, however, it can also be provided that the lock logic arrangement 1 and the locking mechanism 3 are arranged separately from one another and, in particular, are arranged in separate housings.
  • Fig. 2 shows that the lock logic arrangement 1 has a lock mechanism 10 and an actuator 11, wherein the lock mechanism 10 can be brought into different lock states by means of the actuator 11, which are shown in FIG Figures 3a, 3c and in Figures 4a, 4b are shown.
  • the locking mechanism 3 can be opened in the assembled state of the motor vehicle lock arrangement 2 as a function of the mechanical lock states by mechanical, manual actuation of the outside door handle 7 and possibly the inside door handle 8.
  • the mechanical, manual actuation of the outside door handle 7 relates here to a movement of the outside door handle 7 carried out by the operator, which is passed through to the pawl 5 of the locking mechanism 3 depending on the state of the lock.
  • the lock mechanism 10 is equipped with a push-push mechanism 12, by means of which the lock mechanism 10 can be adjusted to different lock states.

  • an adjustable switching element 16 which can be brought into at least two switching positions, preferably in at least three switching positions, here and preferably in four switching positions, via switching movements 17.
  • the switching element 16 in the course of a push movement 14 the switching element 16 out of a switching position ( Fig. 3a ) in a switching movement 17 a new switching position ( Figure 3c ) takes.
  • the switching element 16 retains its switching position.
  • the push-push mechanism 12 is assigned a latching spring arrangement 18 which fixes the switching element 16 in a latching manner.
  • a latching spring arrangement 18 which fixes the switching element 16 in a latching manner.
  • the detent spring assembly 18 is initially tensioned and then locked.
  • the detent spring assembly 18 is tensioned, but not over-locked.

  • the input element 13 is preferably already disengaged from the switching element 16.

  • a further counter-engagement part 20 comes into the range of movement of the engagement part 19 here and preferably corresponds to the transition of the Figure 3b on Figure 3c , in which the switching element 16 has reached its new switching position.
  • a loading movement 15 of the input element 13, as can be seen from the transition from Fig. 3a 3b results only in a minor effect on the switching element 16, but does not influence the switching position of the switching element 16.
  • the switching element 16 executes an evasive movement out of the range of movement of the input element 13, without overriding the detent spring arrangement 18. This means that the switching element 16, driven by the detent spring arrangement 18, falls back into its switching position as soon as the engagement part 19 has pivoted past the counter-engagement part 20 of the switch element 16.

  • the switching element 16 is designed here and preferably to be endlessly rotatable. This means that the switching element 16 is, as it were, rotated further by one switching position with each switching movement 17. This also means that several switch positions can be implemented, each of which can generate a different lock state.

  • the switching element 16 has two switching positions which generate the “locked” lock state. This corresponds to the in Figure 3c shown switching position and a switching position in which the switching element 16 is again rotated 180 °.
  • the switching element 16 alternately assumes the switching positions generating the different lock states by means of its adjustment.
  • the detent spring assembly 18 is, as in FIG Fig. 3 visible, implemented in a particularly simple way.

  • the latching spring arrangement 18 is latched between the tensioning and releasing of the detent spring arrangement 18.
  • the detent spring arrangement 18 is resiliently supported on the counter detent surface 22 of the switching element 16.
  • the detent spring arrangement 18 has a detent spring 23 which is formed at least in sections, here and preferably completely, from a spring wire. The design of the detent spring 23 in the manner of a leg spring is shown and is preferred in this respect.
  • the detent spring arrangement 18 Of particular importance for the proposed function of the detent spring arrangement 18 is the shape of the counter-detent surface 22 such that the detent spring 23, which is resiliently supported on the counter-detent surface 22, engages in the counter-detent surface 22 when the respective switching position is reached.

Description

Die Erfindung betrifft eine Schlosslogikanordnung für eine Kraftfahrzeugschlossanordnung gemäß dem Oberbegriff von Anspruch 1 und eine Kraftfahrzeugschlossanordnung als solche gemäß dem Oberbegriff von Anspruch 15.The invention relates to a lock logic arrangement for a motor vehicle lock arrangement according to the preamble of claim 1 and a motor vehicle lock arrangement as such according to the preamble of claim 15.

Unter dem Begriff "Kraftfahrzeugschlossanordnung" sind vorliegend alle Arten von Tür-, Hauben- oder Klappenschlossanordnungen zusammengefasst.In the present case, the term "motor vehicle lock arrangement" encompasses all types of door, hood or flap lock arrangements.

Die in Rede stehende Kraftfahrzeugschlossanordnung ist mit einer Schlosslogikanordnung einerseits und einem Sperrwerk andererseits ausgestattet. Während die Schlosslogikanordnung der Einstellung unterschiedlicher Schlosszustände wie "entriegelt" und "verriegelt" dient, sorgt das Sperrwerk für die Aufnahme der Haltekräfte, die für das Halten der jeweiligen Kraftfahrzeugtür o. dgl. erforderlich sind.The motor vehicle lock arrangement in question is equipped with a lock logic arrangement on the one hand and a locking mechanism on the other. While the lock logic arrangement is used to set different lock states such as "unlocked" and "locked", the locking mechanism takes care of the holding forces that are required to hold the respective motor vehicle door or the like.

Die bekannte Schlosslogikanordnung ( DE 20 2013 105 314 U1 ), von der die Erfindung ausgeht, ist einer Kraftfahrzeugschlossanordnung zugeordnet, die im montierten Zustand zumindest mit einem Türaußengriff gekoppelt ist. Die Schlossmechanik weist ein als Zentralverriegelungshebel ausgestaltetes Schaltelement auf, mit dem sich die Schlosszustände "entriegelt" und "verriegelt" einstellen lassen. Im Schlosszustand "entriegelt" lässt sich das Sperrwerk durch eine mechanische Betätigung des Türaußengriffs öffnen, während im Schlosszustand "verriegelt" eine mechanische Betätigung des Türaußengriffs freiläuft oder blockiert wird.The well-known lock logic arrangement ( DE 20 2013 105 314 U1 ), from which the invention is based, is assigned to a motor vehicle lock arrangement which, in the assembled state, is coupled to at least one outside door handle. The lock mechanism has a switching element designed as a central locking lever with which the lock states "unlocked" and "locked" can be set. In the "unlocked" lock state, the locking mechanism can be opened by mechanical actuation of the outside door handle, while in the "locked" lock state a mechanical actuation of the outside door handle is released or blocked.

Die Verstellung des Zentralverriegelungshebels in seine jeweiligen Schaltstellungen erfolgt durch einen Stellantrieb, der über eine Push-Push-Mechanik mit dem Zentralverriegelungshebel gekoppelt ist. Die Push-Push-Mechanik weist einen Eingangshebel, einen am Eingangshebel gelagerten und in eine Mittelstellung federvorgespannten Zwischenhebel und das als Zentralverriegelungshebel ausgestaltete Schaltelement auf. Diese aus drei Hebeln aufgebaute Push-Push-Mechanik ist zwar mechanisch robust, allerdings vergleichsweise aufwendig herzustellen.The central locking lever is adjusted to its respective switching positions by an actuator that is coupled to the central locking lever via a push-push mechanism. The push-push mechanism has an input lever, an intermediate lever mounted on the input lever and spring-preloaded into a central position, and the switching element designed as a central locking lever. This push-push mechanism, made up of three levers, is mechanically robust, but comparatively complex to manufacture.

Bei einer weiteren bekannten Schlosslogikanordnung ( DE 20 2016 100 521 U1 ) findet eine Push-Push-Mechanik Anwendung für die Realisierung einer Kindersicherungsfunktion, mit der ein Türinnengriff bedarfsweise deaktivierbar ist. Eine fertigungstechnische Vereinfachung der obigen Schlosslogikanordnung ergibt sich hieraus nicht.In another known lock logic arrangement ( DE 20 2016 100 521 U1 ) a push-push mechanism is used to implement a child safety function with which an inside door handle can be deactivated if necessary. This does not result in a production-related simplification of the above lock logic arrangement.

Der Erfindung liegt das Problem zugrunde, die bekannte Schlosslogikanordnung derart auszugestalten und weiterzubilden, dass der Aufwand für ihre Herstellung reduziert wird.The invention is based on the problem of designing and developing the known lock logic arrangement in such a way that the cost of its manufacture is reduced.

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

Wesentlich ist die Erkenntnis, dass zur Realisierung einer Push-Push-Funktion, bei der im Zuge einer Push-Bewegung das Schaltelement eine neue Schaltstellung einnimmt und im Zuge einer Lade-Bewegung das Schaltelement seine Schaltstellung beibehält, eine Art Ratschenfunktion zwischen Eingangselement und Schaltelement vorgesehen sein muss. Dies bedeutet, dass die Push-Bewegung des Eingangselements das obige Schalten des Schaltelements bewirkt, während die Lade-Bewegung möglichst keine oder nur eine geringfügige Auswirkung auf das Schaltelement hat.What is essential is the knowledge that a kind of ratchet function is provided between the input element and the switching element in order to implement a push-push function in which the switching element assumes a new switching position during a push movement and the switching element maintains its switching position during a loading movement have to be. This means that the push movement of the input element effects the above switching of the switching element, while the charging movement has as little or no effect as possible on the switching element.

Vorschlagsgemäß ist nun erkannt worden, dass für die oben angesprochene Ratschenfunktion kein zusätzlicher Zwischenhebel erforderlich ist. Vielmehr kann die Ratschenfunktion durch das Schaltelement selbst hergestellt werden, sofern dem Schaltelement eine Rastfederanordnung zugeordnet ist.According to the proposal, it has now been recognized that no additional intermediate lever is required for the ratchet function discussed above. Rather, the ratchet function can be produced by the switching element itself, provided that a locking spring arrangement is assigned to the switching element.

Im Einzelnen wird vorgeschlagen, dass die Rastfederanordnung das Schaltelement in den Schaltstellungen jeweils rastend festlegt. Die Rastfederanordnung wird im Zuge einer Push-Bewegung des Eingangselements von dem Eingangselement gespannt und anschließend überrastet. Im Zuge einer Lade-Bewegung des Eingangselements dagegen wird die Rastfederanordnung von dem Eingangselement lediglich gespannt, jedoch nicht überrastet.In detail, it is proposed that the latching spring arrangement fixes the switching element in a latching manner in each of the switching positions. The detent spring arrangement is tensioned by the input element in the course of a push movement of the input element and then over-locked. In the course of a loading movement of the input element, on the other hand, the detent spring arrangement is only tensioned by the input element, but not over-locked.

Die Rastfederanordnung sorgt dafür, dass das Schaltelement in den Schaltstellungen jeweils einen mechanisch stabilen Gleichgewichtszustand einnimmt. Dies bedeutet, dass eine Auslenkung des Schaltelements aus der jeweilige Schaltstellung heraus gegen die Federkraft der Rastfederanordnung erfolgt. Nach dem obigen Überrasten der Rastfederanordnung stellt die Rastfederanordnung einen mechanisch stabilen Gleichgewichtszustand für die jeweils neue Schaltstellung her, so dass das Schaltelement, getrieben durch die Rastfederanordnung, nach dem Überrasten in die neue Schaltstellung fällt.The locking spring arrangement ensures that the switching element assumes a mechanically stable state of equilibrium in each of the switching positions. This means that the switching element is deflected out of the respective switching position against the spring force of the detent spring arrangement. After the latching spring arrangement has been over-latched, the latching spring arrangement establishes a mechanically stable state of equilibrium for the respective new switching position, so that the switching element, driven by the latching spring arrangement, falls into the new switching position after the latching.

Vorschlagsgemäß ist es also so, dass die Push-Bewegung ein Überrasten der Rastfederanordnung und damit ein federgetriebenes Verstellen des Schaltelements in die neue Schaltstellung bewirkt und dass eine Lade-Bewegung lediglich ein Auslenken des Schaltelements aus der jeweiligen Schaltstellung heraus, nicht jedoch ein Überrasten, bewirkt, so dass nach Abschluss der Lade-Bewegung das Schaltelement, wiederum getrieben von der Rastfederanordnung, zurück in seine ursprüngliche Schaltstellung fallen kann. Es fällt auf, dass sich die Push-Push-Funktion mit der vorschlagsgemäßen Lösung aus lediglich zwei Hebeln und einer Rastfederanordnung realisieren lässt. Ein irgendwie gearteter Zwischenhebel zur Realisierung der Ratschenfunktion ist nicht mehr erforderlich.According to the proposal, the push movement causes the detent spring arrangement to latch and thus a spring-driven adjustment of the switching element into the new switching position and that a loading movement only causes the switching element to be deflected out of the respective switching position, but not latching so that after completion of the loading movement, the switching element, again driven by the locking spring arrangement, can fall back into its original switching position. It is noticeable that the push-push function can be implemented with the proposed solution from just two levers and a locking spring arrangement. An intermediate lever of any kind for realizing the ratchet function is no longer required.

Bei der besonders bevorzugten Ausgestaltung gemäß Anspruch 2 wird die vorschlagsgemäße Schlosslogikanordnung für die Realisierung einer Zentralverriegelungsfunktion, in Einzelnen für die Realisierung der Schlosszustände "entriegelt" und "verriegelt" genutzt. Die nicht zuletzt aufgrund der geringen Teileanzahl erreichbare, hohe mechanische Robustheit der vorschlagsgemäßen Schlosslogikanordnung führt dazu, dass die vorschlagsgemäße Schlosslogikanordnung für die in einem Kraftfahrzeug am höchsten frequentierte Zentralverriegelungsfunktion besonders geeignet ist.In the particularly preferred embodiment according to claim 2, the proposed lock logic arrangement is used for the implementation of a central locking function, in particular for the implementation of the lock states "unlocked" and "locked". The high mechanical robustness of the proposed lock logic arrangement, which is achievable not least because of the small number of parts, means that the proposed lock logic arrangement is particularly suitable for the central locking function that is most frequently used in a motor vehicle.

Die weiter bevorzugte Ausgestaltung gemäß Anspruch 3 betrifft die Nutzung der Rastfederanordnung für die Umsetzung eines zweiten Teils der Schaltbewegung des Schaltelements, in dem das Eingangselement bereits außer antreibenden Eingriff von dem Schaltelement gekommen ist. Hierdurch lässt sich der antreibende Eingriff zwischen dem Eingangselement und dem Schaltelement auf konstruktiv besonders einfache Weise umsetzen. Bei der besonders bevorzugten Ausgestaltung gemäß Anspruch 5 bewirkt eine Push-Bewegung stets eine Schaltbewegung in ein und derselben Bewegungsrichtung. Dabei ist das Schaltelement vorzugsweise endlos drehbar ausgebildet. Unterschiedliche Antriebsrichtungen sind für die Verstellung des Schaltelements also nicht erforderlich, was den konstruktiven Aufbau weiter vereinfacht.The further preferred embodiment according to claim 3 relates to the use of the detent spring arrangement for the implementation of a second part of the switching movement of the switching element in which the input element has already come out of driving engagement from the switching element. As a result, the driving engagement between the input element and the switching element can be implemented in a structurally particularly simple manner. In the particularly preferred embodiment according to claim 5, a push movement always causes a switching movement in one and the same direction of movement. The switching element is preferably designed to be endlessly rotatable. Different drive directions are therefore not required for the adjustment of the switching element, which further simplifies the structural design.

Die vorschlagsgemäße Lösung erlaubt gemäß den Ansprüchen 9 bis 12, dass der Stellantrieb unidirektional ausgelegt ist (Anspruch 9). Für die Rückstellung des Eingangselements ist entsprechend eine Rückstellfeder gemäß Anspruch 10 vorgesehen, die gegen die Antriebsrichtung des Eingangselements wirkt.According to claims 9 to 12, the proposed solution allows the actuator to be designed unidirectionally (claim 9). For resetting the input element, a resetting spring according to claim 10 is provided, which acts against the drive direction of the input element.

Eine Ausgestaltung gemäß den Ansprüchen 9 und 10 lässt sich am besten durch eine besonders bevorzugte Ausgestaltung gemäß Anspruch 11 realisieren, bei der der Antrieb des Eingangselements über ein flexibles Zugmittel, insbesondere ein Seil, ein Band oder eine Kette, erfolgt. Dies lässt sich nicht nur auf fertigungstechnisch einfache Weise, sondern auch kostengünstig umsetzen.An embodiment according to claims 9 and 10 can best be realized by a particularly preferred embodiment according to claim 11, in which the input element is driven via a flexible traction means, in particular a rope, a belt or a chain. This can be implemented not only in a simple manner in terms of production engineering, but also inexpensively.

Bei der besonders bevorzugten Ausgestaltung gemäß Anspruch 12 ist die Lade-Bewegung des Eingangselements vom Antriebsmotor des Stellantriebs getrieben, während die Push-Bewegung von der Rückstellfederanordnung getrieben ist. Dies ermöglicht beispielsweise eine vergleichsweise schwache Auslegung des Antriebsmotors, da die Bewegung in Antriebsrichtung des Eingangselements nicht notwendigerweise mit hoher Geschwindigkeit erfolgen muss. Anders ist dies bei der Rückstellbewegung, bei der es sich hier und vorzugsweise ja um die Push-Bewegung handelt, die das gewünschte Schalten des Schaltelements möglichst schnell bewirken muss. Die weiter bevorzugten Ausgestaltungen gemäß den Ansprüchen 13 und 14 betreffen fertigungstechnisch einfach zu realisierende und insbesondere kompakt bauende Varianten für eine Zentralverriegelungskupplung, die von dem Schaltelement angesteuert wird. Interessant dabei ist speziell die Ausgestaltung gemäß Anspruch 14, bei der das Kupplungselement zumindest in einer Bewegungskomponente in Richtung der Rotationsachsen der Kupplungshebel verstellbar ist. Eine Verstellung des Kupplungselements quer zu den Rotationsachsen der Kupplungshebel, die stets Bauraum erfordert, ist damit nicht unbedingt erforderlich.In the particularly preferred embodiment according to claim 12, the loading movement of the input element is driven by the drive motor of the actuator, while the push movement is driven by the return spring arrangement. This enables, for example, a comparatively weak design of the drive motor, since the movement in the drive direction of the input element does not necessarily have to take place at high speed. This is different in the case of the return movement, which here and preferably is the push movement, which must bring about the desired switching of the switching element as quickly as possible. The further preferred refinements according to claims 13 and 14 relate to variants for a central locking clutch which is controlled by the switching element and which are easy to implement in terms of manufacturing technology and in particular have a compact design. The embodiment according to claim 14, in which the coupling element is adjustable in at least one movement component in the direction of the axes of rotation of the coupling levers, is of particular interest. An adjustment of the coupling element transversely to the axes of rotation of the coupling levers, which always requires installation space, is therefore not absolutely necessary.

Nach einer weiteren Lehre gemäß Anspruch 15, der eigenständige Bedeutung zukommt, wird eine Kraftfahrzeugschlossanordnung mit einer vorschlagsgemäßen Schlosslogikanordnung und einem Sperrwerk beansprucht, wobei die Kraftfahrzeugschlossanordnung im montierten Zustand mit einem Türaußengriff und ggf. mit einem Türinnengriff gekoppelt ist. Auf alle Ausführungen zu der vorschlagsgemäßen Schlosslogikanordnung darf verwiesen werden.According to a further teaching according to claim 15, which has an independent meaning, a motor vehicle lock arrangement with a proposed Lock logic arrangement and a locking mechanism claimed, wherein the motor vehicle lock arrangement is coupled in the assembled state with an outside door handle and possibly with an inside door handle. Reference may be made to all statements on the proposed lock logic arrangement.

Die vorschlagsgemäße Schlosslogikanordnung 1 ist einer Kraftfahrzeugschlossanordnung 2 zugeordnet. Hinsichtlich der weiten Auslegung des Begriffs "Kraftfahrzeugschlossanordnung" darf auf den einleitenden Teil der Beschreibung verwiesen werden.The proposed lock logic arrangement 1 is assigned to a motor vehicle lock arrangement 2. With regard to the broad interpretation of the term "motor vehicle lock arrangement", reference may be made to the introductory part of the description.

Die Kraftfahrzeugschlossanordnung 2 weist neben der Schlosslogikanordnung 1 ein Sperrwerk 3 auf, das hier und vorzugsweise die üblichen Schließelemente Schlossfalle 4 und Sperrklinke 5 aufweist. Die Schlossfalle 4 lässt sich in eine in Fig. 1 dargestellte Schließstellung bringen, in der sie in haltendem Eingriff mit einem Schließkeil 6 o. dgl. steht. Anstelle des Schließkeils 6 kann auch ein Schließbügel, ein Schließkloben o. dgl. Anwendung finden.The motor vehicle lock arrangement 2 has, in addition to the lock logic arrangement 1, a locking mechanism 3, which here and preferably has the usual locking elements lock latch 4 and locking pawl 5. The lock latch 4 can be converted into an in Fig. 1 Bring the illustrated closed position in which it is in holding engagement with a striker 6 or the like. Instead of the striker 6, a striker, a locking bolt or the like can also be used.

Die Sperrklinke 5 hält die Schlossfalle 4 in ihrer Schließstellung. Für das Öffnen des Sperrwerks 3 lässt sich die Sperrklinke 5 in eine nicht dargestellte, ausgehobene Stellung verstellen, in der sie die Schlossfalle 4 freigibt, so dass die zugeordnete Kraftfahrzeugtür o. dgl. geöffnet werden kann.The pawl 5 holds the latch 4 in its closed position. To open the locking mechanism 3, the pawl 5 can be adjusted into a raised position, not shown, in which it releases the lock latch 4 so that the associated motor vehicle door or the like can be opened.

Im montierten Zustand ist die Kraftfahrzeugschlossanordnung 2 mechanisch mit einem Türaußengriff 7 und ggf. mit einem Türinnengriff 8 gekoppelt. Diese Kopplung erfolgt vorzugsweise über einen Bowdenzug, ein Gestänge o. dgl..In the assembled state, the motor vehicle lock arrangement 2 is mechanically coupled to an outside door handle 7 and possibly to an inside door handle 8. This coupling is preferably done via a Bowden cable, a linkage or the like.

Bei dem in Fig. 1 dargestellten und insoweit bevorzugten Ausführungsbeispiel sind die Schlosslogikanordnung 1 und das Sperrwerk 3 in einer Einheit zusammengefasst und insbesondere in einem Gehäuse 9 aufgenommen. Grundsätzlich kann es aber auch vorgesehen sein, dass die Schlosslogikanordnung 1 und das Sperrwerk 3 separat voneinander angeordnet und insbesondere in separaten Gehäusen angeordnet sind.The in Fig. 1 The illustrated and insofar preferred exemplary embodiment, the lock logic arrangement 1 and the locking mechanism 3 are combined in one unit and, in particular, accommodated in a housing 9. In principle, however, it can also be provided that the lock logic arrangement 1 and the locking mechanism 3 are arranged separately from one another and, in particular, are arranged in separate housings.

Fig. 2 zeigt, dass die Schlosslogikanordnung 1 eine Schlossmechanik 10 und einen Stellantrieb 11 aufweist, wobei die Schlossmechanik 10 mittels des Stellantriebs 11 in unterschiedliche Schlosszustände bringbar ist, die in Fig. 3a, 3c und in Fig. 4a, 4b gezeigt sind. Fig. 2 shows that the lock logic arrangement 1 has a lock mechanism 10 and an actuator 11, wherein the lock mechanism 10 can be brought into different lock states by means of the actuator 11, which are shown in FIG Figures 3a, 3c and in Figures 4a, 4b are shown.

Das Sperrwerk 3 lässt sich im montierten Zustand der Kraftfahrzeugschlossanordnung 2 in Abhängigkeit von den mechanischen Schlosszuständen durch eine mechanische, manuelle Betätigung des Türaußengriffs 7 und ggf. des Türinnengriffs 8 öffnen. Die mechanische, manuelle Betätigung des Türaußengriffs 7 betrifft hier eine vom Bediener durchgeführte Bewegung des Türaußengriffs 7, die zu der Sperrklinke 5 des Sperrwerks 3 in Abhängigkeit vom Schlosszustand durchgeleitet wird.The locking mechanism 3 can be opened in the assembled state of the motor vehicle lock arrangement 2 as a function of the mechanical lock states by mechanical, manual actuation of the outside door handle 7 and possibly the inside door handle 8. The mechanical, manual actuation of the outside door handle 7 relates here to a movement of the outside door handle 7 carried out by the operator, which is passed through to the pawl 5 of the locking mechanism 3 depending on the state of the lock.

Die Schlossmechanik 10 ist mit einer Push-Push-Mechanik 12 ausgestattet, mittels der sich die Schlossmechanik 10 in unterschiedliche Schlosszustände verstellen lässt. Die Push-Push-Mechanik 12 weist ein mittels des Stellantriebs 11 verstellbares Eingangselement 13, das in einer Push-Bewegung 14 und einer entgegengesetzten Lade-Bewegung 15 verstellbar ist. Hier und vorzugsweise sind die Push-Bewegung 14 und die Lade-Bewegung 15 entgegengesetzt, betragsmäßig aber identisch zueinander. Der Betrag einer Bewegung betrifft vorliegend stets den Bewegungsweg.The lock mechanism 10 is equipped with a push-push mechanism 12, by means of which the lock mechanism 10 can be adjusted to different lock states. The push-push mechanism 12 has an input element 13 which can be adjusted by means of the actuating drive 11 and which can be adjusted in a push movement 14 and an opposing loading movement 15. Here, and preferably, the push movement 14 and the loading movement 15 are opposite in terms of amount but identical to each other. In the present case, the amount of a movement always relates to the movement path.

Die Push-Push-Mechanik 12 weist ferner ein verstellbares Schaltelement 16 auf, das über Schaltbewegungen 17 in mindestens zwei Schaltstellungen, vorzugsweise in mindestens drei Schaltstellungen, hier und vorzugsweise in vier Schaltstellungen, bringbar ist. Ganz allgemein ist es vorgesehen, dass im Zuge einer Push-Bewegung 14 das Schaltelement 16 aus einer Schaltstellung heraus (Fig. 3a) in einer Schaltbewegung 17 eine neue Schaltstellung (Fig. 3c) einnimmt. Im Zuge einer Lade-Bewegung 15 dagegen behält das Schaltelement 16 seine Schaltstellung bei.The push-push mechanism 12 also has an adjustable switching element 16, which can be brought into at least two switching positions, preferably in at least three switching positions, here and preferably in four switching positions, via switching movements 17. In general, it is provided that in the course of a push movement 14 the switching element 16 out of a switching position ( Fig. 3a ) in a switching movement 17 a new switching position ( Figure 3c ) takes. In the course of a loading movement 15, however, the switching element 16 retains its switching position.

Wesentlich ist für die vorschlagsgemäße Lösung, dass der Push-Push-Mechanik 12 eine Rastfederanordnung 18 zugeordnet ist, die das Schaltelement 16 jeweils rastend festlegt. Dies ist in den Fig. 3a, 3b und 3c gezeigt. Im Zuge einer Push-Bewegung des Eingangselements 13, die sich aus dem Übergang von Fig. 3b auf Fig. 3c ergibt, wird die Rastfederanordnung 18 zunächst gespannt und anschließend überrastet. Im Zuge einer Lade-Bewegung 15 des Eingangselements 13, die sich aus dem Übergang von Fig. 3a auf Fig. 3b ergibt, wird die Rastfederanordnung 18 zwar gespannt, jedoch nicht überrastet. Interessant bei der Push-Bewegung 14 ist die Tatsache, dass die Rastfederanordnung 18 nach dem Überrasten wieder entspannt wird, bis das Schaltelement 16 seine neue Schaltstellung eingenommen hat. Damit lässt sich die Rastfederanordnung 18 nutzen, um einen Teil der Push-Bewegung 14 zu bewirken, wie noch erläutert wird.It is essential for the proposed solution that the push-push mechanism 12 is assigned a latching spring arrangement 18 which fixes the switching element 16 in a latching manner. This is in the Figures 3a, 3b and 3c shown. In the course of a push movement of the input element 13, resulting from the transition from Figure 3b on Figure 3c results, the detent spring assembly 18 is initially tensioned and then locked. In the course of a loading movement 15 of the input element 13, resulting from the transition from Fig. 3a on Figure 3b results, the detent spring assembly 18 is tensioned, but not over-locked. What is interesting about the push movement 14 is the fact that the detent spring arrangement 18 is relaxed again after it has been locked until the switching element 16 has assumed its new switching position. The detent spring arrangement 18 can thus be used to effect part of the push movement 14, as will be explained below.

Vorzugsweise handelt es sich bei dem Schaltelement 16 um einen Zentralverriegelungshebel, wobei die Schlossmechanik 10 in Abhängigkeit von der Schaltstellung des Schaltelements 16 im Schlosszustand "entriegelt", indem eine mechanische, manuelle Betätigung des Türaußengriffs 7 das Sperrwerk 3 öffnet, oder im Schlosszustand "verriegelt", indem eine mechanische, manuelle Betätigung des Türaußengriffs 7 freiläuft oder blockiert wird, steht. Fig. 3a zeigt die den Schlosszustand "entriegelt" erzeugende Schaltstellung, während Fig. 3c die den Schlosszustand "verriegelt" erzeugende Schaltstellung zeigt.The switching element 16 is preferably a central locking lever, the lock mechanism 10 "unlocking" depending on the switching position of the switching element 16 in the lock state by mechanical, manual actuation of the outside door handle 7 opening the locking mechanism 3 or "locking" in the lock state by a mechanical, manual actuation of the outside door handle 7 freewheels or is blocked. Fig. 3a shows the switch position generating the "unlocked" lock state, while Figure 3c shows the switch position generating the lock state "locked".

Durch die vorschlagsgemäße Ausstattung der Push-Push-Mechanik 12 mit einer Rastfederanordnung 18 kann es ohne weiteres vorgesehen sein, dass die Rastfederanordnung 18 nach dem Überrasten zumindest einen Teil der Schaltbewegung des Schaltelements 16 in die neue Schaltstellung bewirkt. In besonders bevorzugter Ausgestaltung ist es entsprechend so, dass jede Push-Bewegung 14 nur einen ersten Teil einer Schaltbewegung des Schaltelements 16 in Richtung der neuen Schaltstellung und das Überrasten der Rastfederanordnung 18 bewirkt, wodurch die Rastfederanordnung 18 den zweiten Teil der Schaltbewegung des Schaltelements 16 in die nächste Schaltstellung hinein bewirkt. Im zweiten Teil der Schaltbewegung des Schaltelements 16 steht das Eingangselement 13 vorzugsweise bereits außer Eingriff von dem Schaltelement 16.By equipping the push-push mechanism 12 with a detent spring arrangement 18 as proposed, it can readily be provided that the detent spring arrangement 18 after locking causes at least part of the switching movement of the switching element 16 into the new switching position. In a particularly preferred embodiment, it is correspondingly so that each push movement 14 causes only a first part of a switching movement of the switching element 16 in the direction of the new switching position and the locking of the detent spring arrangement 18, whereby the detent spring arrangement 18 in the second part of the switching movement of the switching element 16 causes the next switch position in. In the second part of the switching movement of the switching element 16, the input element 13 is preferably already disengaged from the switching element 16.

Im Einzelnen ist es hier und vorzugsweise so, dass das Eingangselement 13 mindestens einen Eingriffsteil 19, hier und vorzugsweise genau ein Eingriffsteil 19, aufweist und das Schaltelement 16 mindestens ein Gegeneingriffsteil 20, hier und vorzugsweise vier Gegeneingriffsteile 20, aufweist. Im Zuge einer Push-Bewegung 14 kommt nun ein Eingriffsteil 19 des Eingangselements 13 mit einem Gegeneingriffsteil 20 des Schaltelements 16 in Eingriff, wodurch das Schaltelement 16 um den ersten Teil der Schaltbewegung bewegt wird. Da dies mit einem Überrasten der Rastfederanordnung 18 verbunden ist, sorgt die Rastfederanordnung 18 wie oben angesprochen für den zweiten Teil der Schaltbewegung 17. Im Zuge des zweiten Teils der Schaltbewegung 17 kommt hier und vorzugsweise ein weiteres Gegeneingriffsteil 20 in den Bewegungsbereich des Eingriffsteils 19. Dies entspricht dem Übergang der Fig. 3b auf Fig. 3c, in der das Schaltelement 16 seine neue Schaltstellung erreicht hat.In detail, it is here and preferably so that the input element 13 has at least one engagement part 19, here and preferably precisely one engagement part 19, and the switching element 16 has at least one counter-engagement part 20, here and preferably four counter-engagement parts 20. In the course of a push movement 14, an engagement part 19 of the input element 13 now comes into engagement with a counter-engagement part 20 of the switching element 16, whereby the switching element 16 is moved by the first part of the switching movement. Since this is associated with an overlocking of the detent spring arrangement 18, the detent spring arrangement 18 provides, as mentioned above, the second part of the switching movement 17. In the course of the second part of the switching movement 17, a further counter-engagement part 20 comes into the range of movement of the engagement part 19 here and preferably corresponds to the transition of the Figure 3b on Figure 3c , in which the switching element 16 has reached its new switching position.

Eine Lade-Bewegung 15 des Eingangselements 13, wie sich aus dem Übergang von Fig. 3a auf 3b ergibt, hat nur eine geringfügige Auswirkung auf das Schaltelement 16, beeinflusst jedoch die Schaltstellung des Schaltelements 16 nicht. Im Einzelnen vollzieht das Schaltelement 16 im Zuge der Lade-Bewegung 15, getrieben durch das Eingangselement 13, eine Ausweichbewegung aus dem Bewegungsbereich des Eingangselements 13 heraus, ohne die Rastfederanordnung 18 zu überrasten. Dies bedeutet, dass das Schaltelement 16, getrieben durch die Rastfederanordnung 18, zurück in seine Schaltstellung fällt, sobald das Eingriffsteil 19 an dem Gegeneingriffsteil 20 des Schaltelements 16 vorbeigeschwenkt ist.A loading movement 15 of the input element 13, as can be seen from the transition from Fig. 3a 3b results only in a minor effect on the switching element 16, but does not influence the switching position of the switching element 16. Specifically, in the course of the loading movement 15, driven by the input element 13, the switching element 16 executes an evasive movement out of the range of movement of the input element 13, without overriding the detent spring arrangement 18. This means that the switching element 16, driven by the detent spring arrangement 18, falls back into its switching position as soon as the engagement part 19 has pivoted past the counter-engagement part 20 of the switch element 16.

Hier und vorzugsweise sind das Eingangselement 13 und/oder das Schaltelement 16 jeweils um eine Rotationsachse 13a, 16a schwenkbar. Die Rotationsachsen 13a, 16a von Eingangselement 13 und Schaltelement 16 sind parallel zueinander, jedoch beabstandet voneinander angeordnet.Here and preferably the input element 13 and / or the switching element 16 can each be pivoted about an axis of rotation 13a, 16a. The axes of rotation 13a, 16a of input element 13 and switching element 16 are arranged parallel to one another, but spaced from one another.

Bemerkenswert ist bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel, dass sich das Schaltelement 16 mit jeder Push-Bewegung 14 des Eingangselements 13 in einer Schaltbewegung 17 mit ein und derselben Bewegungsrichtung bewegt. Letztlich ist das Schaltelement 16 hier und vorzugsweise endlos drehbar ausgebildet. Dies bedeutet, dass das Schaltelement 16 mit jeder Schaltbewegung 17 gewissermaßen um eine Schaltstellung weitergedreht wird. Dies bedeutet auch, dass mehrere Schaltstellungen realisiert sein können, die jeweils einen unterschiedlichen Schlosszustand erzeugen können.It is noteworthy in the illustrated and insofar preferred exemplary embodiment that the switching element 16 moves with each push movement 14 of the input element 13 in a switching movement 17 with one and the same direction of movement. Ultimately, the switching element 16 is designed here and preferably to be endlessly rotatable. This means that the switching element 16 is, as it were, rotated further by one switching position with each switching movement 17. This also means that several switch positions can be implemented, each of which can generate a different lock state.

Hier und vorzugsweise ist es allerdings vorgesehen, dass das Schaltelement 16 mindestens zwei, hier und vorzugsweise vier, unterschiedliche Schaltstellungen aufweist, die ein und denselben Schlosszustand erzeugen. Bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel weist das Schaltelement 16 zwei den Schlosszustand "entriegelt" erzeugende Schaltstellungen auf. Dies entspricht der in Fig. 3a gezeigten Schaltstellung sowie einer Schaltstellung, bei der das Schaltelement 16 um 180° weitergedreht ist. Ferner weist das Schaltelement 16 zwei den Schlosszustand "verriegelt" erzeugende Schaltstellungen auf. Dies entspricht der in Fig. 3c dargestellten Schaltstellung sowie einer Schaltstellung, bei der das Schaltelement 16 wiederum um 180° weitergedreht ist.Here and preferably, however, it is provided that the switching element 16 has at least two, here and preferably four, different switching positions that produce one and the same lock state. In the exemplary embodiment shown, which is preferred in this respect, the switching element 16 has two switching positions which generate the “unlocked” lock state. This corresponds to the in Fig. 3a switching position shown as well as a switching position in which the switching element 16 is rotated further by 180 °. In addition, the switching element 16 has two switching positions which generate the “locked” lock state. This corresponds to the in Figure 3c shown switching position and a switching position in which the switching element 16 is again rotated 180 °.

Bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel ist es schließlich vorgesehen, dass das Schaltelement 16 über seine Verstellung die unterschiedliche Schlosszustände erzeugenden Schaltstellungen abwechselnd einnimmt.In the exemplary embodiment shown, which is preferred in this respect, it is finally provided that the switching element 16 alternately assumes the switching positions generating the different lock states by means of its adjustment.

Mit der oben angesprochenen, mehrfachen, hier doppelten Realisierung eines Schlosszustands durch mehrere, hier zwei, Schaltstellungen lässt sich der Betrag der Schaltbewegung reduzieren, da sich eine volle Umdrehung des Schaltelements 16 auf die jeweils vorgesehene Anzahl von Schaltstellungen aufteilt.With the above-mentioned, multiple, here double realization of a lock state through several, here two, switching positions, the amount of the switching movement can be reduced, since a full rotation of the switching element 16 is divided into the respectively intended number of switching positions.

Die Rastfederanordnung 18 ist, wie in Fig. 3 ersichtlich, auf besonders einfache Weise umgesetzt. Die Rastfederanordnung 18 weist eine Rastfläche 21 auf, während das Schaltelement 16 eine Gegenrastfläche 22 aufweist. Rastfläche 21 und Gegenrastfläche 22 stehen derart miteinander in Eingriff oder lassen sich zumindest derart miteinander in Eingriff bringen, dass eine Verstellung des Schaltelements 16 zwischen zwei Schaltstellungen mit einem Spannen und einem Entspannen der Rastfederanordnung 18 verbunden ist. Zwischen dem Spannen und dem Entspannen der Rastfederanordnung 18 ist, wie oben erläutert, das Überrasten der Rastfederanordnung 18 vorgesehen. Wie ebenfalls in Fig. 3 gezeigt, stützt sich die Rastfederanordnung 18 an der Gegenrastfläche 22 des Schaltelements 16 federnd ab. Hierfür weist die Rastfederanordnung 18 eine Rastfeder 23 auf, die zumindest abschnittsweise, hier und vorzugsweise vollständig, aus einem Federdraht gebildet ist. Dargestellt und insoweit bevorzugt ist die Ausgestaltung der Rastfeder 23 nach Art einer Schenkelfeder.The detent spring assembly 18 is, as in FIG Fig. 3 visible, implemented in a particularly simple way. The detent spring arrangement 18 has a detent surface 21, while the switching element 16 has a counter-detent surface 22. Locking surface 21 and Mating latching surfaces 22 are in engagement with one another or can at least be brought into engagement with one another in such a way that an adjustment of the switching element 16 between two switching positions is connected with tensioning and releasing the latching spring arrangement 18. As explained above, the latching spring arrangement 18 is latched between the tensioning and releasing of the detent spring arrangement 18. As in Fig. 3 As shown, the detent spring arrangement 18 is resiliently supported on the counter detent surface 22 of the switching element 16. For this purpose, the detent spring arrangement 18 has a detent spring 23 which is formed at least in sections, here and preferably completely, from a spring wire. The design of the detent spring 23 in the manner of a leg spring is shown and is preferred in this respect.

Von besonderer Bedeutung für die vorschlagsgemäße Funktion der Rastfederanordnung 18 ist die Formgestaltung der Gegenrastfläche 22 derart, dass die Rastfeder 23, die sich an der Gegenrastfläche 22 federnd abstützt, beim Erreichen der jeweiligen Schaltstellung in die Gegenrastfläche 22 einrastet. Entsprechend ist zur Erzeugung der Rastwirkung die Gegenrastfläche 22 im Querschnitt quer zu der Rotationsachse 16a des Schaltelements 16 mehreckig, vorzugsweise sternförmig, ausgestaltet. Um die Rastwirkung weiter zu verstärken, ist die Rastfläche 21 an der Rastfeder 23 komplementär zu der Gegenrastfläche 22 geformt. Bei dem dargestellten Ausführungsbeispiel bedeutet dies, dass die Rastfeder 23 einen Knick 23a aufweist.Of particular importance for the proposed function of the detent spring arrangement 18 is the shape of the counter-detent surface 22 such that the detent spring 23, which is resiliently supported on the counter-detent surface 22, engages in the counter-detent surface 22 when the respective switching position is reached. Correspondingly, in order to generate the locking effect, the counter-locking surface 22 is configured to be polygonal, preferably star-shaped, in cross section transverse to the axis of rotation 16a of the switching element 16. In order to further strengthen the latching effect, the latching surface 21 on the latching spring 23 is shaped complementary to the counter-latching surface 22. In the illustrated embodiment, this means that the detent spring 23 has a kink 23a.

Die antriebstechnische Kopplung des Stellantriebs 11 mit dem Eingangselement 13 ist bei dem dargestellten Ausführungsbeispiel auf die Push-Push-Mechanik 12 hin optimiert. Dabei ist es vorzugsweise so, dass der Stellantrieb 11 mit dem Eingangselement 13 lediglich unidirektional antriebstechnisch gekoppelt ist, so dass das Eingangselement 13 mittels des Stellantriebs 11 nur in einer einzigen Antriebsrichtung 24 des Eingangselements 13 verstellbar ist. Die Rückstellung des Eingangselements 13 erfolgt federgetrieben, indem eine Rückstellfederanordnung 25 vorgesehen ist, die gegen die Antriebsrichtung 24 auf das Eingangselement 13 wirkt.The drive coupling of the actuator 11 to the input element 13 is optimized for the push-push mechanism 12 in the illustrated embodiment. In this case, it is preferably the case that the actuating drive 11 is only drive-coupled to the input element 13 in a unidirectional manner, so that the input element 13 can only be adjusted in a single drive direction 24 of the input element 13 by means of the actuating drive 11. The return of the input element 13 takes place in a spring-driven manner in that a return spring arrangement 25 is provided which acts against the drive direction 24 on the input element 13.

Durch die obige, unidirektional vorgesehene, antriebstechnische Kopplung des Stellantriebs 11 mit dem Eingangselement 13 lässt sich ein flexibles Zugmittel 26 zwischen Stellantrieb 11 und Eingangselement 13 schalten. Im Einzelnen ist es vorgesehen, dass der Stellantrieb 11 einen Antriebsmotor 27 aufweist, wobei die antriebstechnische Kopplung zwischen dem Antriebsmotor 27 und dem Eingangselement 13 ein flexibles Zugmittel 26, hier und vorzugsweise ein Seil, ein Band oder eine Kette, aufweist. In besonders bevorzugter Ausgestaltung ist das Eingangselement 13, wie in der Zeichnung dargestellt, als Seilscheibe ausgestaltet, auf das das flexible Zugmittel 26 aufwickelbar bzw. von dem das flexible Zugmittel abwickelbar ist.The above unidirectional drive coupling of the actuator 11 to the input element 13 enables a flexible traction means 26 to be switched between the actuator 11 and the input element 13. In detail is it is provided that the actuator 11 has a drive motor 27, the drive coupling between the drive motor 27 and the input element 13 having a flexible traction means 26, here and preferably a rope, a belt or a chain. In a particularly preferred embodiment, the input element 13, as shown in the drawing, is designed as a pulley onto which the flexible traction means 26 can be wound or from which the flexible traction means can be unwound.

Die Lade-Bewegung 15 des Eingangselements 13 ist hier und vorzugsweise vom Antriebsmotor 27 getrieben und in Antriebsrichtung 24 des Eingangselements 13 gerichtet, während die Push-Bewegung 14 hier und vorzugsweise von der Rückstellfederanordnung 25 getrieben und gegen die Antriebsrichtung 24 gerichtet ist. Damit kann die motorgetriebene Lade-Bewegung 15, bei der die Rückstellfederanordnung 15 gespannt wird, vergleichsweise langsam erfolgen, da mit dieser Lade-Bewegung 15, wie oben erläutert, kein Schalten des Schaltelements 16 einher geht. Beispielsweise wäre es denkbar, dass die Lade-Bewegung 15 bereits vorgenommen wird, bevor der Bediener, beispielsweise über eine Funkfernbedienung, eine Änderung des Schlosszustands auslöst. Grundsätzlich ist es aber auch denkbar, dass die Lade-Bewegung 15 erst vorgenommen wird, wenn der Bediener die Änderung des Schlosszustands auslöst.The loading movement 15 of the input element 13 is here and preferably driven by the drive motor 27 and directed in the drive direction 24 of the input element 13, while the push movement 14 is here and preferably driven by the return spring arrangement 25 and directed against the drive direction 24. The motor-driven loading movement 15, during which the return spring arrangement 15 is tensioned, can thus take place comparatively slowly, since this loading movement 15, as explained above, is not accompanied by any switching of the switching element 16. For example, it would be conceivable that the loading movement 15 is already carried out before the operator triggers a change in the lock state, for example via a radio remote control. In principle, however, it is also conceivable that the loading movement 15 is only carried out when the operator triggers the change in the lock state.

Für die Realisierung der Schlosszustände "entriegelt" und "verriegelt" weist die Schlossmechanik 10 eine Zentralverriegelungskupplung 28 auf, die einen konstruktiv besonders einfachen Aufbau zeigt. Die Zentralverriegelungskupplung 28 weist, wie in Fig. 4 dargestellt, einen ersten Kupplungshebel 29, der im montierten Zustand mit dem Sperrwerk 3, insbesondere mit der Sperrklinke 5, verbunden ist, einen zweiten Kupplungshebel 30, der im montierten Zustand mit dem Türaußengriff 7 verbunden ist, sowie einen in eine Kuppelstellung (Fig. 4a) und in eine Entkuppelstellung (Fig. 4b) verstellbares Kupplungselement 31 auf. Die beiden Kupplungshebel 29, 30 sind in Abhängigkeit von der Stellung des Kupplungselements 31 miteinander gekuppelt oder voneinander entkuppelt, wobei das Kupplungselement 31 durch das Schaltelement 16 verstellbar ist. Hierfür weist das Schaltelement 16, wie aus einer Zusammenschau der Fig. 3 und 4 hervorgeht, eine Führungskulisse 32 auf, die das Kupplungselement 31 in Abhängigkeit von der Schaltstellung des Schaltelements 16 in die Kuppelstellung (Fig. 4a) oder in die Entkuppelstellung (Fig. 4b) auslenkt oder freigibt. Hierfür ist das Kupplungselement 31 mittels einer Kupplungsfeder 32, hier und vorzugsweise in die Entkuppelstellung, vorgespannt.For the implementation of the “unlocked” and “locked” lock states, the lock mechanism 10 has a central locking clutch 28 which has a particularly simple construction. The central locking clutch 28 has, as in Fig. 4 shown, a first clutch lever 29, which in the assembled state is connected to the locking mechanism 3, in particular to the pawl 5, a second clutch lever 30, which is connected to the outside door handle 7 in the assembled state, and one in a coupling position ( Figure 4a ) and in a decoupling position ( Figure 4b ) adjustable coupling element 31. The two clutch levers 29, 30 are coupled to one another or decoupled from one another as a function of the position of the coupling element 31, the coupling element 31 being adjustable by the switching element 16. For this purpose, the switching element 16, as from a synopsis of the Fig. 3 and 4th emerges, a guide slot 32, which the coupling element 31 depending on the switching position of the switching element 16 in the coupling position ( Figure 4a ) or in the uncoupling position ( Figure 4b ) deflects or releases. This is for this The coupling element 31 is prestressed by means of a coupling spring 32, here and preferably in the uncoupling position.

Bei dem dargestellten und insoweit bevorzugten Ausführungsbeispiel sind die Rotationsachsen 29a, 30a der beiden Kupplungshebel 29, 30 parallel zueinander, weiter vorzugsweise koaxial, ausgerichtet. Dabei ist das Kupplungselement 31 zumindest in einer Bewegungskomponente entlang der Schwenkachsen 29a, 30a der Kupplungshebel 29, 30 verstellbar.In the exemplary embodiment shown and in this respect preferred, the axes of rotation 29a, 30a of the two clutch levers 29, 30 are aligned parallel to one another, more preferably coaxially. The coupling element 31 is adjustable in at least one movement component along the pivot axes 29a, 30a of the coupling levers 29, 30.

Das Kupplungselement 31 ist, wie in Fig. 4 gezeigt, vorzugsweise an einem der Kupplungshebel, hier am ersten Kupplungshebel 29, schwenkbar angelenkt. Es weist eine Führungsfläche 33 auf, die mit der Führungskulisse 32 des Schaltelements 16 in Eingriff steht.The coupling element 31 is, as in Fig. 4 shown, preferably on one of the clutch levers, here on the first clutch lever 29, pivotably articulated. It has a guide surface 33 which engages with the guide slot 32 of the switching element 16.

Die Rotationsachse 16a des Schaltelements 16 ist parallel zu und vorzugsweise beabstandet von den Rotationsachsen 29a, 30a der beiden Kupplungshebel 29, 30 ausgerichtet. Die Führungskulisse 32 stellt eine bezogen auf die Rotationsachse 16a des Schaltelements 16 axial ausgerichtete Lauffläche für die Führungsfläche 33 des Kupplungselements 31 bereit. Dadurch, dass hier und vorzugsweise zwei Schaltstellungen vorgesehen sind, um den Schlosszustand "entriegelt" zu erzeugen, ist das Schaltelement 16 mit zwei Führungskulissen 32 ausgestattet, die bezogen auf die Rotationsachse 16a des Schaltelements 16 um 180° versetzt zueinander angeordnet sind.The axis of rotation 16a of the switching element 16 is aligned parallel to and preferably at a distance from the axes of rotation 29a, 30a of the two clutch levers 29, 30. The guide slot 32 provides a running surface for the guide surface 33 of the coupling element 31 that is axially aligned with respect to the axis of rotation 16a of the switching element 16. The fact that here and preferably two switch positions are provided to produce the "unlocked" lock state, the switching element 16 is equipped with two guide slots 32, which are arranged offset from one another by 180 ° with respect to the axis of rotation 16a of the switching element 16.

Nach einer weiteren Lehre, der eigenständige Bedeutung zukommt, wird eine Kraftfahrzeugschlossanordnung 2 mit einer Schlosslogikanordnung 1 und einem Sperrwerk 3 beansprucht, wobei die Kraftfahrzeugschlossanordnung 2 im montierten Zustand mechanisch mit einem Türaußengriff 7 und ggf. mit einem Türinnengriff 8 gekoppelt ist. Bei der Schlosslogikanordnung 1 handelt es sich um eine vorschlagsgemäße Schlosslogikanordnung, so dass insoweit auf alle obigen Ausführungen verwiesen werden darf.According to a further teaching, which is of independent importance, a motor vehicle lock arrangement 2 with a lock logic arrangement 1 and a locking mechanism 3 is claimed, the motor vehicle lock arrangement 2 being mechanically coupled to an outside door handle 7 and possibly to an inside door handle 8 in the assembled state. The lock logic arrangement 1 is a proposed lock logic arrangement, so that reference may be made to all of the above statements.
