Description

Die Erfindung betrifft ein Kraftfahrzeug-Türschloß nach dem Oberbegriff von Anspruch 1.The invention relates to a motor vehicle door lock according to the preamble of claim 1.

Das bekannte Kraftfahrzeug-Türschloß, von dem die Erfindung ausgeht (DE-C 3 220 705), weist einen Übertragungshebel auf, der einarmig etwa mittig an dem Außenauslösehebel schwenkbar gelagert ist. Der Übertragungshebel weist einen sich etwa entlang der Einfallsrichtung der Sperrklinke axial erstreckenden Kulissenschlitz auf, in welchen ein abgekröpfter Ansatz des Außensicherungshebels als Kulissenstein eingreift. Bei Betätigung des Außensicherungshebels, der im übrigen mit dem Innensicherungshebel durch eine Steckverbindung bewegungsgekuppelt ist, wird der Übertragungshebel hin und her geschwenkt, die Kulissenverbindung erlaubt aber zugleich eine translatorische Bewegung des Übertragungshebels bei Betätigung des Außenauslösehebels. An seinem freien Ende ist der Übertragungshebel mit einer nach außen freigeschnittenen langlochartigen Kupplungsöffnung versehen, deren Längsachse sich ebenfalls in Axialrichtung des Übertragungshebels erstreckt. Der freigeschnittene Bereich der Kupplungsöffnung ist von einem quer zur Einfallsrichtung vorragenden Quersteg und von einem etwa in Einfallsrichtung vorragenden Längssteg begrenzt, zwischen denen eine Durchgangsöffnung gebildet ist. Befindet sich der hier vorhandene Mitnehmerzapfen der Sperrklinke in Höhe der Durchgangsöffnung, so kann der Übertragungshebel durch den Außensicherungshebel bzw. den Innensicherungshebel geschwenkt werden. Bei geöffneter Schloßfalle und Sperrklinke hingegen befindet sich der Mitnehmerzapfen im hinterschnittenen Bereich der Kupplungsöffnung. In diesem Fall kann der Übertragungshebel nicht geschwenkt werden. Er blockiert damit in diesem Zustand die Bewegung des Außensicherungshebels und des Innensicherungshebels, die also in diesem Zustand in Entsicherungsstellung blockiert sind.The known motor vehicle door lock, from which the invention is based (DE-C 3 220 705), has a transmission lever which is pivotably mounted with one arm approximately centrally on the outer release lever. The transmission lever has a link slot that extends axially approximately along the direction of incidence of the pawl, in which a cranked extension of the external securing lever engages as a link block. When the outer locking lever, which is otherwise coupled to the inner locking lever by a plug connection, is actuated, the transmission lever is pivoted back and forth, but the link connection also allows a translational movement of the transmission lever when the outer trigger lever is actuated. At its free end, the transmission lever is provided with an outwardly cut slot-like coupling opening, the longitudinal axis of which likewise extends in the axial direction of the transmission lever. The cut-away area of the coupling opening is delimited by a transverse web projecting transversely to the direction of incidence and by a longitudinal web projecting approximately in the direction of incidence, between which a through opening is formed. If the pawl of the pawl present here is at the level of the through opening, the transmission lever can be pivoted through the external locking lever or the internal locking lever. When the lock latch and pawl are open, however, the driver pin is located in the undercut area of the coupling opening. In this case, the transmission lever cannot be swiveled. He thus blocks the movement of the external locking lever and the internal locking lever in this state, which are therefore blocked in this state in the unlocked position.

Mit der zuvor erläuterten Konstruktion wird erreicht, daß bei geöffneter Fahrertür die Fahrertür nicht abgeschlossen oder durch Drücken des Türknöpfchens von innen gesichert werden kann, da ansonsten die Gefahr besteht, daß man das Kraftfahrzeug bei im Kraftfahrzeug liegendem Türschlüssel verriegelt.With the construction explained above it is achieved that when the driver's door is open the driver's door cannot be locked or secured from the inside by pressing the doorknob, since otherwise there is a risk that the motor vehicle will be locked when the door key is in the motor vehicle.

Das zuvor erläuterte Kraftfahrzeug-Türschloß hat auch die Möglichkeit, einen Zentralverriegelungsantrieb mit Hilfe eines Zentralverriegelungshebels am Außensicherungshebel und am Innensicherungshebel angreifen zu lassen.The motor vehicle door lock explained above also has the possibility of having a central locking drive engage on the external locking lever and on the internal locking lever with the aid of a central locking lever.

Bei einer Mehrstellenverriegelung, wie sie zunehmend bei Zentralverriegelungen gefordert wird, stellt sich mit dem zuvor erläuterten, bekannten Kraftfahrzeug-Türschloß das Problem, daß die Blockierung des Außensicherungshebels und des Innensicherungshebels bei geöffneter Schloßfalle und Sperrklinke auch gegenüber dem Zentralverriegelungsantrieb wirkt, wenn dieser beispielsweise von der Beifahrertür oder von der Kofferklappe her in Richtung der Sicherungsstellung aktiviert wird. Man kann hier eine elektronische Speicherschaltung vorsehen, die den Schaltbefehl für den Zentralverriegelungsantrieb des Kraftfahrzeug-Türschlosses der noch offenstehenden Tür speichert. Das ist aber technisch aufwendig.In a multi-point locking system, as is increasingly required for central locking systems, the known motor vehicle door lock explained above has the problem that the blocking of the external locking lever and the internal locking lever when the lock latch and pawl is open also acts on the central locking drive, for example if the latter operates from Passenger door or from the trunk lid is activated in the direction of the securing position. An electronic memory circuit can be provided here, which stores the switching command for the central locking drive of the motor vehicle door lock of the door which is still open. But that is technically complex.

Der Erfindung liegt folglich die Aufgabe zugrunde, das bekannte Kraftfahrzeug-Türschloß unter Berücksichtigung der Voraussetzungen bei einer Mehrstellenverriegelung über eine vorgesehene Zentralverriegelung mechanisch auszugestalten und weiterzubilden.The invention is therefore based on the object of mechanically designing and developing the known motor vehicle door lock, taking into account the requirements for a multi-point locking system, via a central locking system.

Die zuvor aufgezeigte Aufgabe ist bei einem Kraftfahrzeug-Türschloß mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst. Erfindungsgemäß wird von dem bei der eingangs erläuterten, elektronischen Lösung mit einer Speicherschaltung vorgesehenen Konzept der Gleichbehandlung von Handbetätigung und Zentralverriegelungs-Betätigung abgegangen. Unter Berücksichtigung und Analyse der Voraussetzungen bei einer mechanischen Lösung des zuvor erläuterten Problems bei Mehrstellenverriegelungen wird vielmehr zwischen Handbetätigung einerseits und Betätigung durch die Zentralverriegelung bzw. durch den Zentralverriegelungsantrieb unterschieden. Für die Handbetätigung bleibt es bei der im Stand der Technik bekannten Blockierung des Außensicherungshebels und des ggf. ebenfalls blockierten Innensicherungshebels bei geöffneter Schloßfalle und Sperrklinke. Für den Eingriff vom Zentralverriegelungsantrieb her, also über den Zentralverriegelungshebel hingegen wird die Blockierung des Außensicherungshebels und des ggf. ebenfalls blockierten Innensicherungshebels lösbar gestaltet. Damit trägt man der Tatsache Rechnung, daß eine Verriegelung von einer anderen Stelle als beispielsweise der Fahrerseite des Kraftfahrzeugs her ja denkgesetzlich voraussetzt, daß der Fahrer oder die sonstige Bedienungsperson den Fahrzeugschlüssel in der Hand hält.The object presented above is achieved in a motor vehicle door lock with the features of the preamble of claim 1 by the features of the characterizing part of claim 1. According to the invention, the concept of equal treatment of manual actuation and central locking actuation provided in the electronic solution with a memory circuit provided in the introduction is abandoned. Taking into account and analyzing the prerequisites for a mechanical solution to the problem explained above with multi-point locking systems, a distinction is made between manual operation on the one hand and operation by the central locking or by the central locking drive. For manual operation it remains with the blocking of the external securing lever and the possibly also blocked internal securing lever known in the prior art when the lock latch and pawl are open. For the procedure on the other hand, from the central locking drive, that is to say via the central locking lever, the blocking of the external securing lever and the possibly also blocked internal securing lever is made releasable. This takes into account the fact that locking from a position other than, for example, the driver's side of the motor vehicle requires that the driver or the other operator holds the vehicle key in his hand.

Bei dem eingangs erläuterten, bekannten Kraftfahrzeug-Türschloß kann die Blockierung des Außensicherungshebels bei geöffneter Schloßfalle und Sperrklinke dadurch überwunden werden, daß man bei der Betätigung des Außensicherungshebels gleichzeitig den Außenauslösehebel zieht. Dadurch wird nämlich dort der Übertragungshebel translatorisch in axialer Richtung bewegt, so daß der Mitnehmerzapfen der Sperrklinke in den Bereich der Durchgangsöffnung des Übertragungshebels kommt. Dann aber ist die vom Außensicherungshebel her ausgelöste Schwenkbewegung des Übertragungshebels wieder möglich. Diese Konzeption könnte man auch in Verbindung mit der Lehre der Erfindung einsetzen, indem man nämlich den Zentralverriegelungsantrieb bzw. den Zentralverriegelungshebel auf den Übertragungshebel zwecks translatorischer Bewegung wirken läßt.In the known motor vehicle door lock explained at the outset, the blocking of the external locking lever when the lock latch and pawl are open can be overcome by simultaneously pulling the external release lever when the external locking lever is actuated. As a result, the transmission lever is translationally moved there in the axial direction, so that the driver pin of the pawl comes into the region of the through opening of the transmission lever. But then the pivoting movement of the transmission lever triggered by the external securing lever is possible again. This concept could also be used in conjunction with the teaching of the invention, namely by allowing the central locking drive or the central locking lever to act on the transmission lever for the purpose of translatory movement.

Bei einer bevorzugten Ausgestaltung des erfindungsgemäßen Kraftfahrzeug-Türschlosses ist jedoch anders als in der zuvor erläuterten ersten konstruktiven Konkretisierung der Lehre ein zusätzlicher Blockierhebel vorgesehen und entsprechend den Merkmalen des Anspruchs 3 angeordnet. Das erlaubt eine größere konstruktive Freiheit bei der Gestaltung der Schließmechanik des Kraftfahrzeug-Türschlosses.In a preferred embodiment of the motor vehicle door lock according to the invention, however, in contrast to the previously explained first structural specification of the teaching, an additional blocking lever is provided and arranged in accordance with the features of claim 3. This allows greater design freedom in the design of the locking mechanism of the motor vehicle door lock.

Weitere vorteilhafte Ausgestaltungen sind Gegenstand der weiteren Unteransprüche.Further advantageous embodiments are the subject of the further subclaims.

Für weitere Erläuterungen der Lehre der Erfindung wird auf die Erläuterung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung verwiesen.For further explanations of the teaching of the invention reference is made to the explanation of a preferred embodiment with reference to the drawing.

Die Fig. 1 und 2 der Zeichnung zeigen schematisch, untereinander, die beiden an einer Tragplatte eines erfindungsgemäßen Kraftfahrzeug-Türschlosse im Winkel angeordneten Bereiche der Schließmechanik in Sicherungsstellung, wobei Fig. 2 eine Ansicht in Fig. 1 von links darstellt.1 and 2 of the drawing show schematically, one below the other, the two areas of the locking mechanism arranged at an angle on a support plate of a motor vehicle door lock according to the invention in the locking position, FIG. 2 showing a view in FIG. 1 from the left.

Das in den Fig. 1 und 2, die man stets im Zusammenhang betrachten muß, dargestellte Kraftfahrzeug-Türschloß weist eine nicht dargestellte Schloßfalle und eine nicht dargestellte Sperrklinke auf. Im dargestellten und insoweit bevorzugten Ausführungsbeispiel gilt dabei, daß zur Betätigung der Sperrklinke ein Mitnehmerzapfen 1 vorgesehen ist, der in Fig. 2 in seiner untersten Stellung, bei eingefallener Sperrklinke, also geschlossener Schloßfalle zu sehen ist. Die Schließmechanik weist eine das Rückgrat der gesamten Konstruktion bildende, winkelförmige Tragplatte 2 sowie einen Innenauslösehebel 3 zur Auslösung des Türschlosses von innen, einen Außenauslösehebel 4 zur Auslösung des Türschlosses von außen, beispielsweise über eine in einen Befestigungsclip 5 eingehakte Stange von einem Außen-Schließzylinder her betätigbaren, nämlich um eine Schwenkachse 6 schwenkbaren Außenauslösehebel 4, einen Innensicherungshebel 7, dargestellt in Fig. 1, zumeist verbunden mit einem sogenannten Innensicherungsknöpfchen, einen mit dem Innensicherungshebel 7 gekuppelten, in Fig. 2 erkennbaren Außensicherungshebel 8, einen auf den Innensicherungshebel 7 und den Außensicherungshebel 8 drückenden, an einem nicht dargestellten Zentralverriegelungsantrieb anschließbaren Zentralverriegelungshebel 9 und, jedenfalls im hier dargestellten Ausführungsbeispiel einen Übertragungshebel 10 auf. Der Innensicherungshebel 7 weist eine Mitnehmerkulisse 11 auf, in der eine in Fig. 2 erkennbare Mitnehmernase 12 des Außensicherungshebels 8 kuppelnd eingreift. Am der Schwenkachse 13 gegenüberliegenden Ende des Außensicherungshebels 8 befindet sich ein Gestängeclip 14 zur Einhängung einer mit dem Schließzylinder des Kraftfahrzeug-Türschlosses verbundenen Stange. Der Zentralverriegelungshebel 9 ist in Fig. 1 in strichpunktierten Linien auch noch in Entsicherungsstellung dargestellt. Er greift mit einem Mitnehmerzapfen 15 in eine Ausnehmung 16 im Innensicherungshebel 7 zu dessen Mitnahme ein. Wegen der Kupplung mit dem Außensicherungshebel 8 wird insoweit dann vom Zentralverriegelungshebel 9 auch der Außensicherungshebel 8 mitgenommen.The motor vehicle door lock shown in FIGS. 1 and 2, which must always be considered in connection, has a lock latch, not shown, and a pawl, not shown. In the illustrated and in this respect preferred embodiment, it applies that a driving pin 1 is provided for actuating the pawl, which can be seen in FIG. The locking mechanism has an angled support plate 2, which forms the backbone of the entire construction, and an inside release lever 3 for releasing the door lock from the inside, an outside release lever 4 for releasing the door lock from outside, for example via a rod hooked into a fastening clip 5 from an outside lock cylinder Actuatable, namely pivotable about a pivot axis 6 external release lever 4, an interior locking lever 7, shown in Fig. 1, mostly connected to a so-called interior locking button, an external locking lever 8 coupled to the interior locking lever 7, recognizable in Fig. 2, one on the interior locking lever 7 and the External locking lever 8 pushes on central locking lever 9, which can be connected to a central locking drive (not shown) and, at least in the exemplary embodiment shown here, a transmission lever 10. The inner locking lever 7 has a driver link 11, in which a driver lug 12 of the outer locking lever 8, which can be seen in FIG. 2, engages in a coupling manner. At the end of the external locking lever 8 opposite the pivot axis 13 there is a linkage clip 14 for hanging a rod connected to the locking cylinder of the motor vehicle door lock. The central locking lever 9 is also shown in broken lines in Fig. 1 in the unlocked position. He engages with a driver pin 15 in a recess 16 in the inner locking lever 7 to take it. Because of the coupling with the external locking lever 8, the central locking lever is then used 9 also the external locking lever 8 is taken along.

Der Außensicherungshebel 8 ist in Fig. 2 in T-Form dargestellt und weist am unteren Ende eine gebogene Langlochkulisse 17 auf, in der ein Übertragungszapfen 18 läuft. Der Übertragungszapfen 18 kann bei Betätigen des Außenauslösehebels 4 in der in Fig. 2 erkennbaren Stellung am freien Ende des Übertragungshebels 10 frei vorbeigeschwenkwt werden, wird aber der Außensicherungshebel 8 um die Schwenkachse 13 im Uhrzeigersinn in Entsicherungsstellung geschwenkt, so kommt der Übertragungszapfen 18 an einer Übertragungsfläche 30 am Übertragungshebel 10 zur Anlage. Wird dann der Außenauslösehebel 4 (oder der Innenauslösehebel 3) betätigt, so wird der Übertragungshebel 10 um sein in Fig. 2 links liegendes, an der Tragplatte 2 schwenkbar gelagertes Ende hochgeschwenkt, wodurch dann der Mitnehmerzapfen 1 an der Sperrklinke angehoben und die Sperrklinke geöffnet wird.The external locking lever 8 is shown in T-shape in FIG. 2 and has a curved slot link 17 at the lower end, in which a transmission pin 18 runs. The transmission pin 18 can be swiveled freely past the free end of the transmission lever 10 when the outer release lever 4 is actuated in the position shown in FIG 30 on the transmission lever 10 to the system. If the outer release lever 4 (or the inner release lever 3) is then actuated, the transmission lever 10 is pivoted upward about its end on the left in FIG. 2, which is pivotably mounted on the support plate 2, as a result of which the driving pin 1 on the pawl is raised and the pawl is opened .

Wesentlich ist nun, daß aus den in der Beschreibungseinleitung erläuterten Gründen der Außensicherungshebel 8 und, im hier dargestellten Ausführungsbeispiel, auch der Innensicherungshebel 7 bei geöffneter Schloßfalle und Sperrklinke in Entsicherungsstellung blockiert ist bzw. sind. Dabei ist erfindungsgemäß vorgesehen, daß die Blockierung des Außensicherungshebels 8 und des ggf. ebenfalls blockierten Innensicherungshebels 7 bei geöffneter Schloßfalle und Sperrklinke durch Bewegung des Zentralverriegelungshebels 9 in Richtung der in den Figuren dargestellten Sicherungsstellung lösbar und danach der Außensicherungshebel 8 und ggf. auch der Innensicherungshebel 7 mit dem Zentralverriegelungshebel 9 weiter in Sicherungsstellung bringbar ist bzw. sind.It is now essential that, for the reasons explained in the introduction to the description, the external locking lever 8 and, in the exemplary embodiment shown here, the internal locking lever 7 is or are blocked in the unlocked position when the lock latch and pawl are open. It is provided according to the invention that the blocking of the external locking lever 8 and the possibly also blocked internal locking lever 7 when the lock latch and pawl is open can be released by moving the central locking lever 9 in the direction of the locking position shown in the figures and then the external locking lever 8 and possibly also the internal locking lever 7 with the central locking lever 9 can be brought into the securing position.

Dazu ist im hier dargestellten Ausführungsbeispiel ein zusätzlicher Blockierhebel 19 vorgesehen, der bei in Entsicherungsstellung befindlichem Außensicherungshebel 8 (und hier auch Innensicherungshebel 7) und geöffneter Schloßfalle und Sperrklinke zwischen einer Blockierfläche 20 am Außensicherungshebel 8 und einer Gegenfläche 21 an einem ortsfesten Teil, hier an der Tragplatte 2, in Blockierstellung einfällt. Im hier dargestellten Ausführungsbeispiel ist eine Feder 22 in Form einer Doppel-Schwenkelfeder zur Belastung des Blockierhebels 19 in Richtung der Blockierstellung vorgesehen.For this purpose, an additional locking lever 19 is provided in the exemplary embodiment shown here, which, when the external locking lever 8 is in the unlocking position (and here also the internal locking lever 7) and the open latch and pawl between a locking surface 20 on the external locking lever 8 and a counter surface 21 on a stationary part, here on the support plate 2, engages in the blocking position. In the exemplary embodiment shown here, a spring 22 is provided in the form of a double swivel spring for loading the blocking lever 19 in the direction of the blocking position.

Betrachtet man Fig. 2, so kann in der dargestellten Sicherungsstellung der Blockierhebel 19 nicht in Blockierstellung einfallen. Dieser Blockierhebel 19 ist aber am Außensicherungshebel 8 mittels der Schwenkachse 23 schwenkbar gelagert. Wird nun der Außensicherungshebel 8 in Fig. 2 um die Schwenkachse 23 im Uhrzeigersinn in Entsicherungsstellung geschwenkt, so wird gleichzeitig der Blockierhebel 19 mit verschwenkt. Er kommt dann aber zunächst, bei noch geschlossener Tür, am Mitnehmerzapfen 1 mit einer Anlagefläche 24 zur Anlage. Die Federkraft der Feder 22 reicht nicht aus, den Mitnehmerzapfen 1 nach oben zu drücken. Wird nun aber der Außenauslösehebel 4 beispielsweise betätigt, so wird der Mitnehmerzapfen 1 angehoben, die Sperrklinke wird in Öffnungsstellung gebracht. Gleichzeitig wird die Anlagefläche 24 frei und der Blockierhebel 19 kann weiter im Uhrzeigersinn schwenken. Die in Fig. 2 rechts oben erkennbare Blockiernase 25 kann zwischen der Blockierfläche 20 und der Gegenfläche 21 einfallen und eine Rückbewegung des Außensicherungshebels 8 verhindern.2, the blocking lever 19 cannot engage in the blocking position in the illustrated securing position. This blocking lever 19 is, however, pivotably mounted on the external securing lever 8 by means of the pivot axis 23. If the external locking lever 8 in FIG. 2 is pivoted clockwise about the pivot axis 23 in the unlocking position, the blocking lever 19 is also pivoted at the same time. However, it then comes to rest, with the door still closed, on the driving pin 1 with a contact surface 24. The spring force of the spring 22 is not sufficient to push the driver pin 1 upwards. However, if the external release lever 4 is now actuated, for example, the driver pin 1 is raised and the pawl is brought into the open position. At the same time, the contact surface 24 becomes free and the blocking lever 19 can continue to pivot clockwise. The blocking lug 25 which can be seen at the top right in FIG. 2 can engage between the blocking surface 20 and the counter surface 21 and prevent the outer locking lever 8 from moving back.

Um den zuvor erläuterten, erfindungsgemäß verwirklichten Effekt bei dieser Situation und bei Ansteuerung des Zentralverriegelungsantriebs zu verwirklichen, könnte man den Übertragungshebel 10 selbst beeinflussen. Im dargestellten Ausführungsbeispiel ist aber eine andere Lösung gewählt, nämlich die, daß der Zentralverriegelungshebel 9 den Blockierhebel 19 in seine nicht blockierende Stellung zurückbewegt, und zwar durch Beaufschlagung der Anlagefläche 24 in Fig. 2 nach unten. Dazu ist im dargestellten Ausführungsbeispiel allerdings keine direkte Bewegungskupplung des Zentralverriegelungshebels 9 mit dem Blockierhebel 19 vorgesehen, was durchaus auch möglich wäre, sondern zwischen beiden ist noch ein Hilfshebel 26 angeordnet. Der Hilfshebel 26 ragt mit seiner Betätigungsnase 27, die auch in Fig. 2 zu erkennen ist, in die Bewegungsbahn der Anlagefläche 24. Befindet sich die Anlagefläche 24 des Blockierhebels 19 in gegenüber Fig. 2 angehobener Stellung, ist also die Blockierstellung des Blockierhebels 19 eingenommen, so führt eine Schwenkung des Hilfshebels 26 um seine Schwenkachse 28 im Uhrzeigersinn dazu, daß die Anlagefläche 24 in Fig. 2 wieder nach unten gedrückt, der Blockierhebel 19 also entgegen dem Uhrzeigersinn aus seiner Blockierstellung herausgeschwenkt wird. Diese Bewegung des Hilfshebels 26 wird durch Schwenkung des Zentralverriegelungshebels 9 mit einer entsprechenden Kraftübertragungsplatte 29 erreicht. Dazu hat der Mitnehmerzapfen 15 in der Ausnehmung 16 im Innensicherungshebel 7, wie in Fig. 1 dargestellt, ausreichend Spiel. Auf dem ersten Stück der Bewegung des Zentralverriegelungshebels 9 in Richtung der Sicherungsstellung wird nur der Hilfshebel 26 bewegt und der Blockierhebel 19 aus seiner Blockierstellung angehoben. Auf dem weiteren Weg in Richtung der Sicherungsstellung kommt dann der Mitnehmerzapfen 15 an der in Fig. 1 rechts erkennbaren Kante der Ausnehmung 16 im Innensicherungshebel 7 zur Anlage und beginnt dann auch den Innensicherungshebel 7 in Richtung der Sicherungsstellung mitzunehmen. Da zwischenzeitlich die Blockierung des Außensicherungshebels 8 aufgehoben worden ist, kann die Schwenkung des Innensicherungshebels 7 und des Außensicherungshebels 8 in Sicherungsstellung unbehindert ablaufen.In order to achieve the previously explained effect according to the invention in this situation and when the central locking drive is activated, the transmission lever 10 itself could be influenced. In the illustrated embodiment, however, another solution is chosen, namely that the central locking lever 9 moves the blocking lever 19 back into its non-blocking position, namely by acting on the contact surface 24 in FIG. 2 downwards. For this purpose, however, no direct movement coupling of the central locking lever 9 with the blocking lever 19 is provided in the exemplary embodiment shown, which would also be possible, but an auxiliary lever 26 is arranged between the two. The auxiliary lever 26 projects with its actuating lug 27, which can also be seen in FIG. 2, into the movement path of the contact surface 24. The contact surface 24 of the blocking lever 19 is located in relation to FIG. 2 raised position, that is, the blocking position of the blocking lever 19 is assumed, pivoting the auxiliary lever 26 about its pivot axis 28 in a clockwise direction leads to the bearing surface 24 in FIG is swung out. This movement of the auxiliary lever 26 is achieved by pivoting the central locking lever 9 with a corresponding power transmission plate 29. For this purpose, the driver pin 15 has sufficient play in the recess 16 in the internal securing lever 7, as shown in FIG. 1. On the first part of the movement of the central locking lever 9 in the direction of the securing position, only the auxiliary lever 26 is moved and the blocking lever 19 is lifted out of its blocking position. On the further path in the direction of the securing position, the driver pin 15 then comes to rest on the edge of the recess 16 in the interior locking lever 7, which can be seen on the right in FIG. 1, and then also starts to take the interior locking lever 7 in the direction of the locking position. Since the blocking of the external securing lever 8 has been lifted in the meantime, the pivoting of the internal securing lever 7 and the external securing lever 8 can proceed unhindered in the securing position.

Das dargestellte Ausführungsbeispiel stellt selbstverständlich nur eine Lösungsform für die grundsätzliche Lehre der Erfindung dar, eine Vielzahl anderer Ausgestaltungsmöglichkeiten ist denkbar.The exemplary embodiment shown is of course only one form of solution for the basic teaching of the invention, and a large number of other design options are conceivable.

Die separate Anordnung eines Hilfshebels 26 hat den Vorteil, daß den einbautechnischen Voraussetzungen gerade bei einer winkligen Gestaltung des Kraftfahrzeug-Türschlosses Rechnung getragen werden kann. Der Hilfshebel 26 ist dabei zweckmäßigerweise mit den beiden mit ihm zusammenwirkenden Hebeln jeweils nur in einer Kraftübertragungsrichtung bewegungsgekuppelt.The separate arrangement of an auxiliary lever 26 has the advantage that the installation-technical requirements can be taken into account precisely in the case of an angular design of the motor vehicle door lock. The auxiliary lever 26 is expediently motion-coupled with the two levers interacting with it only in one direction of power transmission.
