Description

Die Erfindung betrifft ein Kraftfahrzeugschloss gemäß dem Oberbegriff von Anspruch 1.The invention relates to a motor vehicle lock according to the preamble of claim 1.

Aus dem Stand der Technik ist eine Vielzahl von Kraftfahrzeugschlössern bekannt. Kraftfahrzeugschlösser finden Anwendung bei allen Arten von Verschlusselementen eines Kraftfahrzeugs. Dazu gehören insbesondere Seitentüren, Hecktüren, Heckklappen, Heckdeckel oder Motorhauben. Diese Verschlusselemente können grundsätzlich auch nach der Art von Schiebetüren ausgestaltet sein.A large number of motor vehicle locks are known from the prior art. Motor vehicle locks are used in all types of locking elements of a motor vehicle. These include, in particular, side doors, rear doors, tailgates, trunk lids or bonnets. These closure elements can in principle also be designed in the manner of sliding doors.

In der DE 10 2004 014 550 A1 ist beispielsweise ein Kraftfahrzeugschloss mit den Schließelementen Sperrklinke und Schlossfalle beschrieben. Das Kraftfahrzeugschloss weist eine Schlossmechanik auf. Diese ist in verschiedene Funktionszustände bringbar. Die Schlossmechanik weist ein in unterschiedliche, den Funktionszuständen entsprechende Funktionsstellungen federelastisch auslenkbares Funktionselement auf. Das Funktionselement ist motorisch in die verschiedenen Funktionsstellungen bringbar. Bei der Verstellung zwischen den verschiedenen Funktionsstellungen wirkt die Rückstellkraft des Funktionselements voll auf den Antriebsstrang des Antriebs. Hierdurch sind für eine sichere Einstellung der Funktionszustände verhältnismäßig starke und damit kostenaufwendige Antriebe für die Verstellung des Funktionselements notwendig.In the DE 10 2004 014 550 A1 For example, a motor vehicle lock with the locking elements pawl and lock latch is described. The motor vehicle lock has a lock mechanism. This can be brought into different functional states. The lock mechanism has a functional element that can be elastically deflected into different functional positions corresponding to the functional states. The functional element can be brought into the various functional positions by a motor. When adjusting between the various functional positions, the restoring force of the functional element acts fully on the drive train of the drive. As a result, relatively strong and therefore costly drives for adjusting the functional element are necessary for a reliable setting of the functional states.

Der vorliegenden Erfindung liegt das Problem zugrunde, ein Kraftfahrzeugschloss gemäß dem Oberbegriff von Anspruch 1 derart auszugestalten und weiterzubilden, dass sich die verschiedenen Funktionszustände kostengünstig umsetzen lassen.The present invention is based on the problem of designing and developing a motor vehicle lock according to the preamble of claim 1 in such a way that the various functional states can be implemented cost-effectively.

Die vorstehende Aufgabe wird bei einem Kraftfahrzeugschloss gemäß dem Oberbegriff von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The above object is achieved in a motor vehicle lock according to the preamble of claim 1 by the features of the characterizing part of claim 1.

Durch das Vorsehen eines Freilaufwegs, in dem das Betätigungselement freiläuft und eines Betätigungswegs, in dem das Betätigungselement das Schließelement betätigt, ist es leicht möglich, verschiedene Funktionszustände bereitzustellen, indem ein Funktionselement die Betätigungsbewegung entweder in den Freilaufweg oder in den Betätigungsweg führt. Hierzu kann das Funktionselement eine Führungskraft auf das Betätigungselement ausüben.By providing a freewheeling path in which the actuating element frees and an actuating path in which the actuating element actuates the closing element, it is easily possible to provide different functional states by having a functional element either the actuating movement in the freewheeling path or leads into the actuation path. For this purpose, the functional element can exert a guiding force on the actuating element.

Da der Kraftfluss der Führungskraft außerhalb des Antriebsstrangs der Antriebsanordnung verläuft, sind nur geringe Antriebskräfte für die Verstellung des Funktionselements notwendig. Führungskräfte oder Betätigungskräfte für das Betätigungselement müssen nicht vom Antriebstrang aufgenommen werden. Der Antrieb für das Funktionselement kann daher entsprechend klein und kostengünstig ausgelegt werden.Since the power flow of the guiding force runs outside the drive train of the drive arrangement, only small drive forces are necessary for the adjustment of the functional element. Managers or operating forces for the operating element do not have to be absorbed by the drive train. The drive for the functional element can therefore be designed to be correspondingly small and inexpensive.

Gemäß einer Weiterbildung der Erfindung wird vorgeschlagen (Anspruch 6), dass das Funktionselement in einer Funktionsstellung die Betätigungsbewegung des Betätigungselements in den Freilaufweg freigibt oder in den Betätigungsweg freigibt. Durch das einfache Einstellen einer Ablenkung werden die beiden Funktionszustände auf besonders einfache Art und Weise realisiert. Zum Führen des Betätigungselements weist das Funktionselement eine Führungskontur auf.According to a development of the invention, it is proposed (claim 6) that the functional element in a functional position releases the actuation movement of the actuation element into the freewheeling path or releases it into the actuation path. By simply setting a deflection, the two functional states are implemented in a particularly simple manner. The functional element has a guide contour for guiding the actuating element.

Um die Crashsicherheit des Kraftfahrzeugschlosses zu erhöhen, kann gemäß Anspruch 10 das Kraftfahrzeugschloss in der Art ausgelegt und ausgebildet sein, dass in einer Funktionsstellung "entriegelt" die Trägheit des Betätigungselements eine Bewegung des Betätigungselements auf den Freilaufweg bewirkt, wenn die Geschwindigkeit der Betätigungsbewegung eine Geschwindigkeitsschwelle überschreitet, und eine Bewegung des Betätigungselements auf den Betätigungsweg bewirkt, wenn die Geschwindigkeit der Betätigungsbewegung eine Geschwindigkeitsschwelle unterschreitet.In order to increase the crash safety of the motor vehicle lock, the motor vehicle lock can be designed and constructed in such a way that in a functional position "unlocked" the inertia of the actuating element causes the actuating element to move on the freewheel path when the speed of the actuating movement exceeds a speed threshold , and causes a movement of the actuating element on the actuating path when the speed of the actuating movement falls below a speed threshold.

Um den Antrieb möglichst schwach auslegen zu können, kann gemäß Anspruch 14 vorgesehen sein, dass die Rotationsachse des Funktionselements maximal 2 cm, vorzugsweise maximal 1 cm, vom Massenmittelpunkt des Funktionselements entfernt ist. Weiter vorzugsweise ist die Rotationsachse des Funktionselements durch den Massenmittelpunkt des Funktionselements geführt.In order to be able to design the drive as weakly as possible, it can be provided according to claim 14 that the axis of rotation of the functional element is a maximum of 2 cm, preferably a maximum of 1 cm, from the center of mass of the functional element. Furthermore, the axis of rotation of the functional element is preferably guided through the center of mass of the functional element.

Fig. 1 zeigt schematisch ein vorschlagsgemäßes Kraftfahrzeugschloss 1. Mit dem Kraftfahrzeugschloss 1 können verschiedenste Verschlusselemente eines Kraftfahrzeugs gehalten werden. Diesbezüglich wird auf den einleitenden Teil verwiesen. Fig. 1 shows schematically a proposed motor vehicle lock 1. The motor vehicle lock 1 can be used to hold a wide variety of locking elements of a motor vehicle. In this regard, reference is made to the introductory part.

Das Kraftfahrzeugschloss 1 weist eine Tragstruktur 2 zur Aufnahme mindestens eines Schließelements 3 und einer Schlossmechanik 5 auf. Die Tragstruktur 2 ist vorzugsweise fest mit einem nicht gezeigten Gehäuse des Kraftfahrzeugschlosses 1 verbunden oder kann einen Teil eines nicht gezeigten Gehäuses des Kraftfahrzeugschlosses 1 bilden.The motor vehicle lock 1 has a support structure 2 for receiving at least one locking element 3 and a lock mechanism 5. The support structure 2 is preferably firmly connected to a housing, not shown, of the motor vehicle lock 1 or can form part of a housing, not shown, of the motor vehicle lock 1.

Hier und vorzugsweise sind an der Tragstruktur 2 die Schließelemente 3 Schlossfalle 3a und Sperrklinke 3b angeordnet. Zum Halten eines Verschlusselements wirken die Schlossfalle 3a und die Sperrklinke 3b in üblicher Weise mit einem Schließkeil 4 zusammen.Here, and preferably, the locking elements 3 lock latch 3a and pawl 3b are arranged on the support structure 2. To hold a locking element, the lock latch 3a and the pawl 3b interact in the usual way with a locking wedge 4.

Die Schlossmechanik 5 ist in unterschiedliche Funktionszustände bringbar. Hierfür weist die Schlossmechanik 5 ein in unterschiedliche, den Funktionszuständen entsprechende Funktionsstellungen verstellbares Funktionselement 6 auf. Das Funktionselement 6 ist bevorzugt aus Kunststoff ausgebildet. Besonders bevorzugt ist das Funktionselement 6 als Kunststoffspritzteil ausgebildet.The lock mechanism 5 can be brought into different functional states. For this purpose, the lock mechanism 5 has a functional element 6 that can be adjusted into different functional positions corresponding to the functional states. The functional element 6 is preferably made of plastic. The functional element 6 is particularly preferably designed as a plastic injection-molded part.

Zur motorischen Verstellung des Funktionselements 6 ist eine Antriebsanordnung 7 mit einem Antriebsstrang 8 zum Funktionselement 6 hin vorgesehen. Für mindestens eine Funktionsstellung des Funktionselements 6 kann ein Anschlag 6a vorgesehen sein. Darüber hinaus können für weitere, insbesondere für alle, Funktionsstellungen des Funktionselements 6 Anschläge vorgesehen sein.For the motorized adjustment of the functional element 6, a drive arrangement 7 with a drive train 8 towards the functional element 6 is provided. A stop 6a can be provided for at least one functional position of the functional element 6. In addition, stops can be provided for further, in particular for all, functional positions of the functional element 6.

Ferner weist das Kraftfahrzeugschloss 1 ein Betätigungselement 9 auf, durch dessen Betätigungsbewegung das mindestens eine Schließelement 3, insbesondere die Sperrklinke 3b, betätigbar ist. Im Ausführungsbeispiel ist das Betätigen des Schließelements 3 das Ausheben der Sperrklinke 3b. Vorzugsweise wird das Betätigungselement 9 durch einen nicht gezeigten Betätigungshebel, insbesondere durch einen Türaußengriff oder einen Türinnengriff betätigt.The motor vehicle lock 1 also has an actuating element 9, the actuating movement of which can actuate the at least one closing element 3, in particular the pawl 3b. In the exemplary embodiment, the actuation of the closing element 3 is the lifting of the pawl 3b. The actuating element 9 is preferably actuated by an actuating lever (not shown), in particular by an outside door handle or an inside door handle.

Das Kraftfahrzeugschloss 1 kann zusätzlich ein nicht gezeigtes weiteres Betätigungselement aufweisen, durch dessen Betätigungsbewegung das mindestens eine Schließelement 3, insbesondere die Sperrklinke 3b, betätigbar ist. Vorzugsweise wird das nicht gezeigte weitere Betätigungselement durch einen nicht gezeigten weiteren Betätigungshebel, insbesondere einen Türinnengriff, betätigt.The motor vehicle lock 1 can additionally have a further actuating element, not shown, by whose actuating movement the at least one locking element 3, in particular the pawl 3b, can be actuated. The further actuating element, not shown, is preferably actuated by a further actuating lever, not shown, in particular an inside door handle.

Das Funktionselement 6 kann in einer Funktionsstellung die Betätigungsbewegung des Betätigungselements 9 entweder in einen Freilaufweg F führen, in dem das Betätigungselement 9 freiläuft, oder in einen Betätigungsweg B führen, indem das Betätigungselement 9 das Schließelement 3 betätigt. Vorzugsweise betätigt das Betätigungselement 9 das Schließelement 3 mittels einer Eingriffskontur 9a. Diese kann als Nase ausgebildet sein. In der Schlossmechanik 5 können weitere Wege, insbesondere für weitere Funktionszustände, für das Betätigungselement 9 vorgesehen sein.In a functional position, the functional element 6 can guide the actuating movement of the actuating element 9 either into a freewheeling path F in which the actuating element 9 frees, or into an actuating path B in which the actuating element 9 actuates the closing element 3. The actuating element 9 preferably actuates the closing element 3 by means of an engagement contour 9a. This can be designed as a nose. In the lock mechanism 5, further paths, in particular for further functional states, can be provided for the actuating element 9.

Dadurch, dass verschiedene Funktionszustände des Kraftfahrzeugschlosses 1 über den Freilaufweg F bzw. den Betätigungsweg B vorgesehen werden, kann die Schlossmechanik 5 mechanisch schwach ausgelegt werden. Die Komponenten der Schlossmechanik 5 müssen nicht zur Aufnahme von Blockadekräften innerhalb der Schlossmechanik 5 dimensioniert werden.The fact that various functional states of the motor vehicle lock 1 can be provided via the freewheeling path F or the actuating path B the lock mechanism 5 are designed to be mechanically weak. The components of the lock mechanism 5 do not have to be dimensioned to absorb blocking forces within the lock mechanism 5.

Zum Führen des Betätigungselements 9 übt das Funktionselement 6 eine Führungskraft auf das Betätigungselement 9 aus. Der Kraftfluss der Führungskraft verläuft außerhalb des Antriebsstrangs 8 der Antriebsanordnung 7. Hierdurch muss der Antriebsstrang 8 keine Führungskräfte und/oder Betätigungskräfte des Betätigungselements 9 zur Bereitstellung der Funktionszustände aufnehmen. Der Antrieb 10 muss lediglich das Funktionselement 6 verstellen und ggf. Reibungskräften durch das Abgleiten des Betätigungselements 9 widerstehen. Er kann entsprechend schwach ausgelegt werden.In order to guide the actuating element 9, the functional element 6 exerts a guiding force on the actuating element 9. The power flow of the management force runs outside the drive train 8 of the drive arrangement 7. As a result, the drive train 8 does not have to absorb any managers and / or actuation forces of the actuation element 9 in order to provide the functional states. The drive 10 only has to adjust the functional element 6 and, if necessary, withstand frictional forces caused by the actuating element 9 sliding off. It can be interpreted accordingly weak.

Hier und vorzugsweise ist das bzw. sind die Schließelemente 3 in einer anderen Ebene des Kraftfahrzeugschlosses 1 angeordnet, als das Funktionselement 6. Das Betätigungselement 6 bewegt sich vorzugsweise in der Ebene des Funktionselements 6.Here and preferably, the locking element 3 is or are arranged in a different plane of the motor vehicle lock 1 than the functional element 6. The actuating element 6 preferably moves in the plane of the functional element 6.

Wie im Ausführungsbeispiel der Fig. 6 gezeigt, können die Schließelemente 3 und das Funktionselement 6 auf unterschiedlichen Seiten der Tragstruktur 2 angeordnet sein. Die Tragstruktur 2 weist dann vorzugsweise eine Ausnehmung 11 zur Kopplung von Schließelement 3 und Funktionselement 6 auf. Hierzu kann eine Eingriffkontur 3c, welche am Schließelement 3, insbesondere der Sperrklinke 3b, oder am Funktionselement 6 ausgebildet sein kann, durch die Ausnehmung 11 ragen. Im Ausführungsbeispiel ist die Eingriffkontur 3c an der Sperrklinke 3b oder einem mit der Sperrklinke 3b gekoppelten Hebel ausgebildet. Sie wird hier und vorzugsweise vom Funktionselement 6 überdeckt.As in the embodiment of Fig. 6 As shown, the closing elements 3 and the functional element 6 can be arranged on different sides of the support structure 2. The support structure 2 then preferably has a recess 11 for coupling the closing element 3 and the functional element 6. For this purpose, an engagement contour 3c, which can be formed on the closing element 3, in particular the locking pawl 3b, or on the functional element 6, protrudes through the recess 11. In the exemplary embodiment, the engagement contour 3c is formed on the pawl 3b or on a lever coupled to the pawl 3b. It is covered here and preferably by the functional element 6.

Der Freilaufweg F und der Betätigungsweg B verlaufen vorzugsweise nebeneinander. Im Ausführungsbeispiel verlaufen der Freilaufweg F und der Betätigungsweg B in Richtung quer zu der Rotationsachse SA, SB eines Schließelements 3 versetzt nebeneinander. Zusätzlich oder alternativ können der Freilaufweg F und der Betätigungsweg B auch in Richtung der Rotationsachse SA, SB eines Schließelements 3 nebeneinander verlaufen. Der Freilaufweg F und der Betätigungsweg B können parallel nebeneinander verlaufen.The freewheeling path F and the actuating path B preferably run next to one another. In the exemplary embodiment, the freewheeling path F and the actuating path B run offset next to one another in the direction transverse to the axis of rotation S A , S B of a closing element 3. Additionally or alternatively, the freewheeling path F and the actuating path B can also run next to one another in the direction of the axis of rotation S A , S B of a closing element 3. The freewheeling path F and the actuating path B can run parallel to one another.

Zum Führen des Betätigungselements 9 weist das Funktionselement 6 eine Führungskontur 6b auf. Vorzugsweise weist die Führungskontur 6b einen stetigen Verlauf auf. Die Führungskontur 6b ist, wie im Ausführungsbeispiel gezeigt, zylinderabschnittsförmig ausgebildet.To guide the actuating element 9, the functional element 6 has a guide contour 6b. The guide contour 6b preferably has a continuous course. As shown in the exemplary embodiment, the guide contour 6b is configured in the shape of a cylinder section.

Das Funktionselement 6 kann gemäß einem weiteren nicht dargestellten Ausführungsbeispiel nach Art einer Weiche ausgebildet sein und mit einer Führungskontur 6b das Betätigungselement 9 entweder in den Freilaufweg F und/oder den Betätigungsweg B führen.According to a further exemplary embodiment, not shown, the functional element 6 can be designed in the manner of a switch and guide the actuating element 9 either into the freewheeling path F and / or the actuating path B with a guide contour 6b.

Vorzugsweise ist die Führungskontor 6b oberflächenbehandelt, insbesondere beschichtet, um ein gutes Gleiten des Betätigungselements 9 entlang der Führungskontur 6b zu gewährleisten. Vorzugsweise ist die Führungskontur 6b mit Kunststoffmaterial beschichtet.
Des Weiteren kann auch die Eingriffskontur 9a des Betätigungselements 9 oberflächenbehandelt, insbesondere beschichtet, sein. Vorzugsweise ist die Eingriffskontur 9a des Betätigungselements 9 mit einem Kunststoffmaterial beschichtet.The guide contour 6b is preferably surface-treated, in particular coated, in order to ensure good sliding of the actuating element 9 along the guide contour 6b. The guide contour 6b is preferably coated with plastic material.
Furthermore, the engagement contour 9a of the actuating element 9 can also be surface-treated, in particular coated. The engagement contour 9a of the actuating element 9 is preferably coated with a plastic material.

Das Kunststoffmaterial zur Ausgestaltung der Führungskontur 6b und/oder der Eingriffskontur 9a kann ein Thermoplastisches Polyester Elastomer (TPE) und/oder ein Polymer-Gleitlagerwerkstoff sein. Als Thermoplastisches Polyester Elastomer haben sich in diesem Zusammenhang insbesondere die kommerziell erhältlichen Werkstoffe Hytrel® 4774, Hytrel® 5526, Hytrel® 6356 von Du-Pont® oder Riteflex® 677 von Ticona® bewährt.The plastic material for designing the guide contour 6b and / or the engagement contour 9a can be a thermoplastic polyester elastomer (TPE) and / or a polymer plain bearing material. In this context, the commercially available materials Hytrel® 4774, Hytrel® 5526, Hytrel® 6356 from Du-Pont® or Riteflex® 677 from Ticona® have proven particularly useful as thermoplastic polyester elastomers.

Als Polymer-Gleitlagerwerkstoff haben sich die kommerziell erhältlichen Werkstoffe Iglidur® G, Iglidur® W 300 und Iglidur® J von Igus®.The commercially available materials Iglidur® G, Iglidur® W 300 and Iglidur® J from Igus® have proven to be the polymer plain bearing material.

Hier und vorzugsweise führt das Funktionselement 6 in einer Funktionsstellung die Betätigungsbewegung des Betätigungselements 9, indem es die Betätigungsbewegung des Betätigungselements 9 in den Betätigungsweg B freigibt. Bei dieser Ausführung führt das Funktionselement 6 in einer anderen Funktionsstellung die Betätigungsbewegung des Betätigungselements 9 auf den Freilaufweg F, vorzugsweise, indem es den Betätigungsweg B sperrt. Weiter vorzugsweise führt das Funktionselement wie zuvor beschrieben entweder auf den Betätigungsweg B oder auf den Freilaufweg F.Here and preferably, the functional element 6 guides the actuation movement of the actuation element 9 in a functional position by releasing the actuation movement of the actuation element 9 in the actuation path B. In this embodiment, the functional element 6 guides the actuating movement of the actuating element 9 onto the freewheeling path F in another functional position, preferably by blocking the actuating path B. As described above, the functional element also preferably leads either to actuation path B or to freewheel path F.

Zusätzlich oder alternativ kann vorgesehen sein, dass das Funktionselement 6 in einer Funktionsstellung die Betätigungsbewegung des Betätigungselements 9 auf den Freilaufweg F freigibt. Bei dieser Ausführung führt das Funktionselement 6 in einer anderen Funktionsstellung die Betätigungsbewegung des Betätigungselements 9 auf den Betätigungsweg B, vorzugsweise, indem es den Freilaufweg F sperrt. Weiter vorzugsweise führt das Funktionselement wie zuvor beschrieben entweder auf den Betätigungsweg B oder auf den Freilaufweg F.Additionally or alternatively, it can be provided that the functional element 6 releases the actuating movement of the actuating element 9 on the freewheeling path F in a functional position. In this embodiment, the functional element 6 guides the actuating movement of the actuating element 9 onto the actuating path B in another functional position, preferably by blocking the free-running path F. As described above, the functional element also preferably leads either to actuation path B or to freewheel path F.

In einer Weiterbildung der Erfindung wird vorgeschlagen, dass das Kraftfahrzeugschloss 1 eine auf das Betätigungselement 9 wirkende Federanordnung 12 aufweist. Die Federanordnung 12 kann eine Schenkelfeder aufweisen. Hier und vorzugsweise spannt die Federanordnung 12 das Betätigungselement 9 gegen das Funktionselement 6 vor. Hierdurch kann eine Bewegungstendenz des Betätigungselements 9 bei der Betätigung bewirkt werden. Im Ausführungsbeispiel bewirkt die Federanordnung 12 eine Bewegungstendenz des Betätigungselements 9 auf den Betätigungsweg B.In a further development of the invention, it is proposed that the motor vehicle lock 1 have a spring arrangement 12 that acts on the actuating element 9. The spring arrangement 12 can have a leg spring. Here, and preferably, the spring arrangement 12 biases the actuating element 9 against the functional element 6. This can cause the actuating element 9 to tend to move during actuation. In the exemplary embodiment, the spring arrangement 12 causes the actuating element 9 to move along the actuating path B.

Hier und vorzugsweise kann das Betätigungselement 9 einen Kulissenstein 9b zur Bewegungsführung des Betätigungselements 9 aufweisen. Der Kulissenstein 9b ist vorzugsweise zumindest teilweise in einer nicht gezeigten Kulisse geführt. Vorzugsweise stellt die Kulisse zumindest eine Bewegungsführung auf einem Teil des Betätigungsweges B und/oder auf einem Teil des Freilaufweges F bereit. Besonders bevorzugt ist die Kulisse geschlossen ausgebildet und stellt eine Bewegungsführung sowohl für den Freilaufweg F als auch für den Betätigungsweg B bereit. Im Ausführungsbeispiel stellt die Kulisse eine Bewegungsführung auf dem Betätigungsweg B und dem Freilaufweg F bereit, während das Funktionselement 6 durch Sperren oder Freigeben das Betätigungselement 9 entweder auf den Betätigungsweg B oder den Freilaufweg F führt.Here and preferably, the actuating element 9 can have a sliding block 9b for guiding the movement of the actuating element 9. The sliding block 9b is preferably at least partially guided in a setting, not shown. The link preferably provides at least one movement guide on part of the actuation path B and / or on part of the freewheel path F. The link is particularly preferably designed to be closed and provides movement guidance for both the freewheeling path F and the actuating path B. In the exemplary embodiment, the link provides movement guidance on the actuation path B and the freewheel path F, while the functional element 6 guides the actuation element 9 either on the actuation path B or the freewheel path F by locking or unlocking.

Im dargestellten Ausführungsbeispiel stellt die Schlossmechanik 5 die Funktion "verriegelt" und "entriegelt", insbesondere über die jeweilige Funktionsstellung des Funktionselements 6, bereit.In the illustrated embodiment, the lock mechanism 5 provides the function “locked” and “unlocked”, in particular via the respective functional position of the functional element 6.

Die Fig. 1 und 2 zeigen das Funktionselement 6 in einer Funktionsstellung "verriegelt". Das Funktionselement 6 versperrt dem Betätigungselement 9 den Betätigungsweg B. Bei der Betätigung des Betätigungselements 9 wird dieses durch die Federanordnung 12 auf das Funktionselement 9 gedrückt und gleitet am Funktionselement 9 ab. Das Betätigungselement 9 wird aufgrund der auf das Funktionselement 6 zurückgehenden Führungskraft, welche hier und vorzugsweise eine Gegenkraft für das Betätigungselement 9 ist, auf dem Freilaufweg F geführt. Hier und vorzugsweise wirkt die Führungskraft senkrecht zur Bewegungsrichtung des Betätigungselements 9.The Fig. 1 and 2 show the functional element 6 in a functional position "locked". The functional element 6 blocks the actuating element 9 from the actuation path B. When the actuating element 9 is actuated, it is pressed onto the functional element 9 by the spring arrangement 12 and slides off the functional element 9. The actuating element 9 is guided on the freewheeling path F due to the guiding force going back to the functional element 6, which here and preferably is a counterforce for the actuating element 9. Here, and preferably, the guide force acts perpendicular to the direction of movement of the actuating element 9.

Auf dem Freilaufweg kann das Schließelement 3 vom Betätigungselement 9 nicht ausgehoben werden, da es außer Eingriff vom Betätigungselement 9 gehalten wird.On the freewheeling path, the closing element 3 cannot be lifted out by the actuating element 9, since it is held out of engagement by the actuating element 9.

Die Fig. 3 zeigt das Funktionselement 6 in einer Funktionsstellung "entriegelt". Bei der Betätigung des Betätigungselements 9 wird das Betätigungselement 9 von der Federanordnung 12 auf den Betätigungsweg B gedrückt. Das Funktionselement 6 führt das Betätigungselement 9, indem es den Betätigungsweg B für das Betätigungselement 9 freigibt. Das Betätigungselement 9 hebt durch die Betätigungsbewegung auf dem Betätigungsweg B das Schließelement 3 aus, wie in Fig. 4 gezeigt. Bei der Betätigung des Schließelements 3, 3a, 3b wirkt hier und vorzugsweise das Betätigungselement 9 getriebefrei auf das Schließelement 3. Der Begriff "getriebefrei" bedeutet hier, dass das Schließelement 3, 3a, 3b ohne die Zwischenschaltung eines Getriebes, insbesondere eines Hebelgetriebes, auf das Schließelement 3 wirkt.The Fig. 3 shows the functional element 6 in a functional position "unlocked". When the actuating element 9 is actuated, the actuating element 9 is pressed onto the actuating path B by the spring arrangement 12. The functional element 6 guides the actuating element 9 by releasing the actuating path B for the actuating element 9. The actuating element 9 lifts the closing element 3 by the actuating movement on the actuating path B, as in FIG Fig. 4 shown. When the closing element 3, 3a, 3b is actuated, the actuating element 9 acts on the closing element 3 in a gear-free manner. The term "gear-free" here means that the closing element 3, 3a, 3b without the interposition of a gear, in particular a lever gear the closing element 3 acts.

Das Betätigungselement 9 wirkt im Ausführungsbeispiel über seine Betätigungskontur 9a indirekt über eine Wirkkontur 6c auf das Schließelement 3, vorliegend die Sperrklinke 3b. Die Wirkkontur 6c ist hier und vorzugsweise am Funktionselement 6 ausgebildet.In the exemplary embodiment, the actuating element 9 acts indirectly via its actuating contour 9a via an active contour 6c on the closing element 3, in the present case the pawl 3b. The active contour 6c is formed here and preferably on the functional element 6.

Gemäß einem anderen Ausführungsbeispiel kann das Betätigungselement 9 auch direkt auf das Schließelement 3, insbesondere die Sperrklinke 3b wirken.According to another exemplary embodiment, the actuating element 9 can also act directly on the closing element 3, in particular the pawl 3b.

Alternativ zu der zuvor beschriebenen Kinematik kann auch im Sinne einer kinematischen Umkehr das Funktionselement 6 in einer Funktionsstellung "entriegelt" den Freigabeweg F sperren bzw. in einer Funktionsstellung "verriegelt" die Federanordnung 12 das Betätigungselement auf den Freigabeweg F drücken und das Funktionselement 6 den Freigabeweg F freigeben.As an alternative to the kinematics described above, the functional element 6 can also block the release path F in a functional position “unlocked” or “lock” it in a functional position in the sense of a kinematic reversal Spring arrangement 12 press the actuating element onto the release path F and the functional element 6 release the release path F.

Vorzugsweise stellt die Schlossmechanik 5 zusätzlich die Funktion "kindergesichert" und/oder "diebstahlgesichert", insbesondere ebenfalls über eine Funktionsstellung des Funktionselements 6, bereit.The lock mechanism 5 preferably also provides the function “child-proof” and / or “theft-proof”, in particular likewise via a functional position of the functional element 6.

Die angesprochenen Funktionszustände betreffen bevorzugt die Möglichkeit des Öffnens eines Verschlusselements eines Kraftfahrzeugs mittels eines Türinnengriffs und mittels eines Türaußengriffs. Im Funktionszustand "verriegelt" kann von innen geöffnet werden, nicht jedoch von außen. Im Funktionszustand "entriegelt" kann sowohl von innen als auch von außen geöffnet werden. Im Funktionszustand "diebstahlgesichert" kann weder von innen noch von außen geöffnet werden. Im Funktionszustand "kindergesichert" kann von innen entriegelt, aber weder von innen noch von außen geöffnet werden.The functional states mentioned preferably relate to the possibility of opening a closure element of a motor vehicle by means of an inside door handle and by means of an outside door handle. In the "locked" functional state, it can be opened from the inside, but not from the outside. In the "unlocked" functional state, it can be opened from the inside as well as from the outside. In the "anti-theft" functional state, it cannot be opened from the inside or outside. In the "child-proof" functional state, it can be unlocked from the inside, but it cannot be opened from the inside or outside.

Ferner lässt sich bei dem vorschlagsgemäßen Kraftfahrzeugschloss 1 eine Crashsicherung auf besonders einfache Art und Weise bereitstellen. Wenn das Kraftfahrzeugschloss 1 in der Art ausgelegt und ausgebildet wird, dass in einer Funktionsstellung "entriegelt" die Trägheit des Betätigungselements 9 eine Bewegung des Betätigungselements 9 auf den Freilaufweg F bewirkt, wenn die Geschwindigkeit der Betätigungsbewegung eine Geschwindigkeitsschwelle überschreitet, und eine Bewegung des Betätigungselements 9 auf dem Betätigungsweg B bewegt wird, wenn die Geschwindigkeit der Betätigungsbewegung eine Geschwindigkeitsschwelle unterschreitet. Dies ist im dargestellten Ausführungsbeispiel der Fall. Das Betätigungselement 9 wird bei einer normalen Betätigung auf dem Betätigungsweg B geführt und die Sperrklinke 3b ausheben. In einer Crashsituation, in der besonders hohe Beschleunigungen auftreten, wird sich das Betätigungselement 9 sehr schnell bewegen, wobei seine Trägheit verhindert, dass die Federanordnung 12 das Betätigungselement in den Betätigungsweg B bewegt, obwohl das Funktionselement 6 den Betätigungsweg B an sich freigegeben hat. Daher wird sich das Betätigungselement 9 in einer Crashsituation in den Freilaufweg F bewegen. Die Sperrklinke 3b wird nicht ausgehoben und das Verschlusselement des Kraftfahrzeugs bleibt geschlossen.Furthermore, in the motor vehicle lock 1 according to the proposal, crash protection can be provided in a particularly simple manner. If the motor vehicle lock 1 is designed and constructed in such a way that in a functional position "unlocks" the inertia of the actuating element 9 causes a movement of the actuating element 9 on the freewheeling path F when the speed of the actuating movement exceeds a speed threshold, and a movement of the actuating element 9 is moved on the actuation path B when the speed of the actuation movement falls below a speed threshold. This is the case in the illustrated embodiment. During normal actuation, the actuating element 9 is guided on the actuating path B and the pawl 3b is lifted out. In a crash situation in which particularly high accelerations occur, the actuating element 9 will move very quickly, its inertia preventing the spring arrangement 12 from moving the actuating element into actuating path B, although functional element 6 has released actuating path B itself. The actuating element 9 will therefore move into the freewheeling path F in a crash situation. The pawl 3b is not lifted and the locking element of the motor vehicle remains closed.

Vorzugsweise ist der Antrieb 10, der das Funktionselement 6 antreibt, nach Art eines Direktantriebs ausgebildet. Bei einem Direktantrieb ist zwischen dem Antrieb 10 und dem Funktionselement 6 keine Getriebeübersetzung angeordnet.The drive 10, which drives the functional element 6, is preferably designed in the manner of a direct drive. In the case of a direct drive, no gear ratio is arranged between the drive 10 and the functional element 6.

Zusätzlich oder alternativ kann die Antriebsanordnung 7 zumindest teilweise in das Funktionselement 6 integriert sein. Beispielsweise können die Spulen 13 oder Permanentmagneten 14 des Antriebs 10 in das Funktionselement 6 integriert sein, beispielsweise, indem das Funktionselement 6 im Kunststoff-Spritzgießverfahren um die Spulen 13 und/oder Permanentmagneten 14 gespritzt wird. Im Allgemeinen können das Funktionselement 6 und der Antrieb 10 kraftschlüssig und/oder formschlüssig und/oder stoffschlüssig miteinander verbunden oder ineinander integriert sein.Additionally or alternatively, the drive arrangement 7 can be at least partially integrated into the functional element 6. For example, the coils 13 or permanent magnets 14 of the drive 10 can be integrated into the functional element 6, for example by the functional element 6 being injected around the coils 13 and / or permanent magnets 14 in a plastic injection molding process. In general, the functional element 6 and the drive 10 can be non-positively and / or positively and / or cohesively connected to one another or integrated into one another.

Im dargestellten und insoweit bevorzugten Ausführungsbeispiel ist der Antrieb 10 als Klauenpolmotor ausgebildet. Er kann jedoch auch gemäß eines anderen Antriebskonzepts ausgebildet sein.In the illustrated and thus preferred exemplary embodiment, the drive 10 is designed as a claw-pole motor. However, it can also be designed according to a different drive concept.

Vorzugsweise ist das Funktionselement 6 rotatorisch und/oder linear zwischen seinen Funktionsstellungen bewegbar. Im dargestellten Ausführungsbeispiel wird das Funktionselement 6 zwischen seinen Funktionsstellungen rotatorisch bewegt.The functional element 6 can preferably be moved rotationally and / or linearly between its functional positions. In the illustrated embodiment, the functional element 6 is rotated between its functional positions.

Die Rotationsachse R des Funktionselements 6 ist parallel, insbesondere koaxial, zu der Rotationsachse SA, SB eines Schließelements 3 und/oder zu der Drehachse D des Antriebs 10 ausgerichtet. Im Ausführungsbeispiel ist die Rotationsachse R des Funktionselements 6 koaxial zu der Rotationsachse SB der Sperrklinke 3b ausgerichtet. Zusätzlich ist die Drehachse D des Antriebs koaxial zu der Rotationsachse SB der Sperrklinke 3b ausgerichtet. Hierdurch ist eine besonders kompakte Ausgestaltung des Kraftfahrzeugschlosses 1 möglich.The axis of rotation R of the functional element 6 is aligned parallel, in particular coaxially, to the axis of rotation S A , S B of a closing element 3 and / or to the axis of rotation D of the drive 10. In the exemplary embodiment, the axis of rotation R of the functional element 6 is aligned coaxially with the axis of rotation S B of the pawl 3b. In addition, the axis of rotation D of the drive is aligned coaxially to the axis of rotation S B of the pawl 3b. This enables a particularly compact design of the motor vehicle lock 1.

Vorzugsweise weist das Kraftfahrzeugschloss 1 mindestens einen Lagerbolzen 15, 16 auf, um welchen das Funktionselement 6 rotatorisch bewegbar ist. Der Lagerbolzen 15, 16 kann zugleich das Statormaterial des Antriebs 10 bilden. In einer solchen Ausbildung sind die Spulen 13 des Antriebs 10 um den Lagerbolzen 15, 16 angeordnet. Zusätzlich kann auf dem Lagerbolzen 15, 16 auch die Sperrklinke 3b oder die Schlossfalle 3a gelagert sein. Vorzugsweise wird über den Lagerbolzen 15, 16 der Kraftfluss der Führungskraft außerhalb des Antriebsstrangs 8 der Antriebsanordnung 7 abgeleitet.The motor vehicle lock 1 preferably has at least one bearing pin 15, 16 about which the functional element 6 can be rotated. The bearing pin 15, 16 can at the same time form the stator material of the drive 10. In such a design, the coils 13 of the drive 10 are arranged around the bearing pin 15, 16. In addition, the pawl 3b or the lock latch 3a can be mounted on the bearing pin 15, 16. Preferably is about the bearing pin 15, 16 derives the power flow of the guide force outside the drive train 8 of the drive arrangement 7.

Zusätzlich oder alternativ kann vorgesehen sein, dass das Funktionselement 6 zumindest über einen Abschnitt formschlüssig geführt wird und insbesondere zumindest ein Teil des Kraftflusses der Führungskraft über den Formschluss verläuft. Ferner kann das Kraftfahrzeugschloss 1 einen nicht gezeigten Anschlag aufweisen, über welchen der Kraftfluss der Führungskraft außerhalb des Antriebsstrangs der Antriebsanordnung abgeleitet wird. In letztem Fall wirkt der Anschlag vorzugsweise mit der Führungskontur 6b zusammen. In diesem Fall kann der Anschlag zugleich eine Führung für das Funktionselement 6 bereitstellen.Additionally or alternatively, it can be provided that the functional element 6 is guided in a form-fitting manner at least over a section and, in particular, at least part of the force flow of the management force runs over the form-fit connection. Furthermore, the motor vehicle lock 1 can have a stop, not shown, via which the flow of force of the guiding force outside the drive train of the drive arrangement is derived. In the latter case, the stop preferably interacts with the guide contour 6b. In this case, the stop can also provide a guide for the functional element 6.

Um die für die Verstellung des Funktionselements 6 notwendigen Kräfte möglichst gering zu halten, ist hier und vorzugsweise vorgesehen, dass die Rotationsachse R des Funktionselements 6 maximal 2 cm, vorzugsweise maximal 1 cm, vom Massemittelpunkt M des Funktionselements 6 entfernt ist. Im insofern bevorzugten, dargestellten Ausführungsbeispiel ist die Rotationsachse R des Funktionselements 6 durch den Massemittelpunkt M des Funktionselements 6 geführt. Eine sich durch die Führungskontur 6b ergebende Masseverschiebung ist durch eine der Führungskontur 6b gegenüberliegende Kontur 6d ausgeglichen.In order to keep the forces necessary for adjusting the functional element 6 as low as possible, it is provided here and preferably that the axis of rotation R of the functional element 6 is a maximum of 2 cm, preferably a maximum of 1 cm, from the center of mass M of the functional element 6. In the exemplary embodiment shown, which is preferred in this respect, the axis of rotation R of the functional element 6 is guided through the center of mass M of the functional element 6. A mass displacement resulting from the guide contour 6b is compensated for by a contour 6d opposite the guide contour 6b.

Das Kraftfahrzeugschloss 1 kann wie zuvor beschrieben ein weiteres Betätigungselement zum Öffnen des Kraftfahrzeugschlosses 1 aufweisen. Vorzugsweise wirkt das weitere Betätigungselement 9 zum Öffnen des Kraftfahrzeugschlosses 1 auf das Funktionselement 6. Hierfür kann das Funktionselement 6 eine zusätzliche Betätigungskontur 6e aufweisen, über welche die Sperrklinke 3b aushebbar ist. Vorzugsweise sind die der Führungskontur 6b gegenüberliegende Kontur 6d und die Betätigungskontur 6e gemeinsam am Funktionselement 6 ausgebildet.As described above, the motor vehicle lock 1 can have a further actuating element for opening the motor vehicle lock 1. The further actuating element 9 preferably acts on the functional element 6 for opening the motor vehicle lock 1. For this purpose, the functional element 6 can have an additional actuating contour 6e, via which the pawl 3b can be lifted out. The contour 6d opposite the guide contour 6b and the actuating contour 6e are preferably formed jointly on the functional element 6.

Hier und vorzugsweise weist das Betätigungselement 9 bzw. ggf. das weitere Betätigungselemente 9 eine Stange und/oder einen Bowdenzug auf.Here and preferably the actuating element 9 or, if applicable, the further actuating element 9 has a rod and / or a Bowden cable.

Ferner weist das Funktionselement 6 vorzugsweise eine Wirkkontur 6c auf, über die der Antrieb 10 die Sperrklinke 3b ausheben kann, wie dies in der Fig. 5 gezeigt ist. Auf diese Weise lässt sich besonders einfach ein Öffnungshilfsantrieb zum motorischen Ausheben der Sperrklinke 3b bereitstellen.Furthermore, the functional element 6 preferably has an active contour 6c, via which the drive 10 can lift the pawl 3b, as shown in FIG Fig. 5 shown is. In this way, an auxiliary opening drive for motorized lifting of the pawl 3b can be provided in a particularly simple manner.

Das vorgeschlagene Kraftfahrzeugschloss 1 weist einen konstruktiv einfachen und kompakten Aufbau auf. Dadurch, dass der Kraftfluss der Führungskraft außerhalb des Antriebsstrangs 8 der Antriebsanordnung 7 verläuft, kann das Funktionselement 6 mit einem sehr schwachen Antrieb 10 bewegt werden. Folglich ist nicht nur ein besonders kompakter, sondern auch kostengünstiger Aufbau des Kraftfahrzeugschlosses 1 möglich.The proposed motor vehicle lock 1 has a structurally simple and compact structure. Because the power flow of the leadership force runs outside the drive train 8 of the drive arrangement 7, the functional element 6 can be moved with a very weak drive 10. Consequently, not only a particularly compact, but also an inexpensive construction of the motor vehicle lock 1 is possible.
