Description

Die Erfindung betrifft einen Mehrfunktionshebel für das Hebelwerk insbesondere eines Kraftfahrzeugtürverschlusses.The invention relates to a multi-function lever for the lever mechanism, in particular a motor vehicle door lock.

Bei zum Beispiel aus FR 1492728 A , WO 03/025319 A1 oder WO 03/018939 A1 bekannten Hebelwerken erfüllen ren einzelne Hebel regelmäßig eine ganz bestimmte Betätigungsfunktion und werden daher für diese Betätigungsfunktion gefertigt und eingesetzt. So kennt man beispielsweise bei Kraftfahrzeugtürverschlüssen mit Drehfalle, Sperrklinke und Auslösehebel für die Betätigung der Sperrklinke einerseits eine mechanische Betätigung für den Auslösehebel und andererseits eine motorische Betätigung. Für die mechanische Betätigung mag man beispielsweise auf einen Bowdenzug, eine Stange etc. zurückgreifen, während die motorische Betätigung einen Elektromotor einsetzt. Zwischen dem Elektromotor und dem Auslösehebel mögen noch ein Getriebe sowie Verbindungsmittel, beispielsweise andere Hebel, ein Bowdenzug, eine Stange etc., zwischengeschaltet sein. So oder so ist der Auslösehebel für die mechanische Betätigung anders ausgebildet als für die motorische Betätigung, so dass zwei verschiedene Auslösehebel zur Verfügung stehen und wahlweise gefertigt bzw. eingesetzt werden müssen. Das hängt davon ab, ob der Kraftfahrzeugtürverschluss für eine mechanische oder motorische Betätigung ausgelegt ist.For example, off FR 1492728 A . WO 03/025319 A1 or WO 03/018939 A1 known leverages meet ren single lever regularly a very specific actuation function and are therefore manufactured and used for this actuation function. So you know, for example, in motor vehicle door locks with catch, pawl and release lever for the operation of the pawl on the one hand, a mechanical operation for the release lever and on the other hand a motorized operation. For mechanical actuation, for example, one may resort to a Bowden cable, a rod, etc., while the motor actuation employs an electric motor. Between the electric motor and the release lever like a gear and connecting means, such as other levers, a Bowden cable, a rod, etc. may be interposed. Either way, the release lever for the mechanical actuation is designed differently than for the motor actuation, so that two different release levers are available and must either be manufactured or used. That depends on whether the motor vehicle door lock is designed for mechanical or motorized operation.

Die bekannte und zuvor beschriebene Vorgehensweise ist in fertigungstechnischer und montagetechnischer Einsicht für jedes beliebige Hebelwerk aufwendig, gleichgültig auf welchem technischen Sachgebiet ein solches Hebelwerk eingesetzt wird. - Hier will die Erfindung Abhilfe schaffen.The well-known and previously described procedure is complicated in manufacturing technology and assembly technical insight for any lever, indifferent to which technical subject area such a leverage is used. - Here the invention wants to remedy the situation.

Der Erfindung liegt das technische Problem zugrunde, einen Mehrfunktionshebel der eingangs beschriebenen Ausführungsform zu schaffen, der sich in einfacher und funktionsgerechter Bauweise durch mehrere Betätigungsfunktionen auszeichnet.The invention is based on the technical problem to provide a multi-function lever of the embodiment described above, which is characterized in a simple and functional design by multiple actuation functions.

Zur Lösung dieses Problems wird ein Mehrfunktionshebel gemäß Anspruch 1 vorgeschlagen. - Die Maßnahmen der Erfindung haben zur Folge, dass ein Mehrfunktionshebel verwirklicht wird, dessen Basishebel für seine ursprüngliche Betätigungsfunktion eingesetzt werden kann. Wenn darüber hinaus mehrere Betätigungsfunktionen verlangt sind, kann dieser Basishebel eine entsprechende Anzahl Hebelglieder für die weiteren verlangten Betätigungsfunktionen aufweisen, die drehfest mit dem Basishebel verbunden werden. Die Hebelglieder werden vorzugsweise mit dem Basishebel vernietet oder auf den Basishebel aufgeclipst. Bei einer Ausführungsform in Stahl ist allerdings auch eine Adhäsivverbindung im Wege des Verschweißens denkbar. Ferner besteht die Möglichkeit, die Hebelglieder mit dem Basishebel gleichachsig zu verbinden, wenn der Basishebel in Ausübung seiner Betätigungsfunktion auf einer Schwenkachse verschwenkbar gelagert ist.To solve this problem, a multi-function lever is proposed according to claim 1. - The measures of the invention have the consequence that a multi-function lever is realized, the base lever can be used for its original operating function. In addition, if more actuation functions are required, this base lever may have a corresponding number of lever members for the other required actuation functions, which are rotatably connected to the base lever. The lever members are preferably riveted to the base lever or clipped onto the base lever. In one embodiment in steel, however, an adhesive connection by means of welding is also conceivable. Furthermore, it is possible to connect the lever members with the base lever coaxially, when the base lever is pivotally mounted in the exercise of its actuation function on a pivot axis.

Nach einer Ausführungsform der Erfindung, der selbständige Bedeutung zukommt, ist ein ein Kraftfahrzeugtürverschluss mit zumindest einer Drehfalle, einer Sperrklinke für die Drehfalle und mit einem Auslösehebel für die Betätigung der Sperrklinke, wobei der Auslösehebel als Basishebel zumindest einen als abzweigendes Hebelglied ausgebildeten Mitnehmerarm aufweist, der mit einem motorisch angetriebenen Mitnehmerrad zusammenwirkt mit einem erfindungsgemäß Mehrfunktionshebel vorgesehen, wobei der Mitnehmerarm mit dem Auslösehebel eine Baueinheit bildet und mit dem Aulösehebel drehfest verbunden ist. Bei dieser Ausführungsform kann also der Auslösehebel einerseits mit beispielsweise einem Bowdenzug mechanisch betätigt werden, jedoch besteht ferner die Möglichkeit, den gleichen Auslösehebel auch motorisch zu betätigen. Dazu arbeitet beispielsweise ein Elektromotor mit einem Ritzel oder Schneckenrad auf das einen Zahnkranz oder Zahnkranzabschnitt aufweisende Mitnehmerrad. Das Mitnehmerrad weist zweckmäßigerweise einen Steuernocken für den Mitnehmerarm auf, der gegen diesen Steuernocken anliegt und dafür sorgt, dass der Auslösehebel bei rotierendem Mitnehmerrad eine Schwenkbewegung zur Betätigung der Sperrklinke ausführt, um also die Sperrklinke einzuklinken oder auszuklinken. Darüber hinaus kann der Auslösehebel als Basishebel im Rahmen der Erfindung aber auch noch eine weitere Betätigungsfunktion erfüllen, wenn nämlich der Auslösehebel auch noch einen Betätigungshebel als abzweigendes Hebelglied aufweist. Über diesen Betätigungshebel kann durch das Verschwenken des Auslösehebels beispielsweise ein Innen- oder Außenbetätigungshebel aber auch ein Zentralverriegelungshebel des Kraftfahrzeugtürverschlusses verstellt werden. Für den Betätigungshebel wie für den Mitnehmerarm gilt; weil es sich um Hebelglieder der eingangs beanspruchten Ausführungsform handelt, dass eine mehrteilige oder einteilige Bauweise mit dem Auslösehebel als Basishebel verwirklicht sein kann. Im Rahmen der mehrteiligen Ausführungsform können der Mitnehmerarm und der Betätigungshebel wiederum mit dem Auslösehebel vernietet oder darauf aufgeclipst sein. Dabei ist eine Ausführungsform aus vorzugsweise Kunststoff aber auch Stahl denkbar. Im ersteren Fall ist auch eine Klebeverbindung denkbar. Im letzteren Fall und bei einteiliger Ausführungsform können der Betätigungshebel und der Mitnehmerarm mit dem Auslösehebel auch verschweißt sein.According to one embodiment of the invention, which is of independent significance, is a motor vehicle door lock with at least one catch, a pawl for the catch and a release lever for the operation of the pawl, wherein the release lever has at least one designed as a branch lever arm member as a lever lever, the lever cooperates with a motor-driven Mitnehmerrad provided with a multi-function lever according to the invention, wherein the Mitnehmerarm forms a structural unit with the release lever and is rotatably connected to the Aulösehebel. In this embodiment, therefore, the release lever on the one hand with a Bowden cable, for example, be mechanically operated, but there is also the possibility to operate the same trip lever and motor. For this purpose, for example, an electric motor with a pinion or worm wheel on the one sprocket or sprocket portion having Mitnehmerrad. The Mitnehmerrad expediently has a control cam for the Mitnehmerarm, which rests against this control cam and ensures that the release lever rotates when the Mitnehmerrad rotates to actuate the pawl, so as to engage the pawl or disengage. In addition, the release lever as a base lever within the scope of the invention but also fulfill another actuation function, namely, when the release lever also has an actuating lever as a branching lever member. About this operating lever can be adjusted by the pivoting of the release lever, for example, an internal or external operating lever but also a central locking lever of the motor vehicle door lock. For the operating lever as well as for the driving arm applies; because it is lever members of the initially claimed embodiment, that a multi-part or one-piece design can be realized with the release lever as the base lever. In the context of the multi-part embodiment of the driving arm and the actuating lever can in turn be riveted to the release lever or clipped on it. In this case, an embodiment of preferably plastic but also steel is conceivable. In the former case, an adhesive connection is conceivable. In the latter case and in one-piece embodiment, the actuating lever and the driving arm can also be welded to the triggering lever.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Es zeigen:

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. Show it:

In den Figuren ist ein Mehrfunktionshebel für das Hebelwerk eines Kraftfahrzeugtürverschlusses dargestellt. Dieser Mehrfunktionshebel weist einen Basishebel 1 für eine erste Betätigungsfunktion und zwei von dem Basishebel 1 abzweigende Hebelglieder 2, 3 für eine zweite und dritte Betätigungsfunktion auf, wobei die Hebelglieder 2, 3 mit dem Basishebel 1 in einteiliger Ausführungsform eine Baueinheit bilden oder aber auch mit dem Basishebel 1 als getrennte Hebelglieder verbunden sein können.In the figures, a multi-function lever for the lever mechanism of a motor vehicle door lock is shown. This multi-function lever has a base lever 1 for a first actuating function and two branching from the base lever 1 lever members 2, 3 for a second and third actuating function, wherein the lever members 2, 3 with the base lever 1 in one-piece embodiment form a structural unit or with the Base lever 1 can be connected as separate lever members.

Im Rahmen des Ausführungsbeispiels nach der Fig. 1 ist lediglich das Hebelglied 3 mit dem Basishebel 1 drehfest verbunden. Dagegen fehlt bei dieser Variante das weitere Hebelglied, weil insofern eine mechanische Betätigung des dargestellten und aus Basishebel 1 sowie Hebelglied 3 zusammengesetzten Auslösehebels 1, 3 verfolgt wird. Demgegenüber wird der Auslösehebel 1, 2, 3 entsprechend der Fig. 2 motorisch betätigt, wobei in diesem Fall das Hebelglied 2 für die Anbindung eines Elektromotors 6 in Verbindung mit seinem Schneckenrad 7 sorgt, welches zusammengenommen ein Mitnehmerrad 5 beaufschlagen. Tatsächlich handelt es sich in diesem Fall bei dem mit dem Basishebel 1 vernieteten Hebelglied 2 um einen Mitnehmerarm, der mit dem motorisch angetriebenen Mitnehmerrad 5 zusammenwirkt.In the context of the embodiment of the Fig. 1 is only the lever member 3 rotatably connected to the base lever 1. By contrast, in this variant, the further lever member is missing, because insofar a mechanical actuation of the illustrated and composed of the base lever 1 and lever member 3 release lever 1, 3 is followed. In contrast, the release lever 1, 2, 3 according to the Fig. 2 operated by a motor, in which case the lever member 2 provides for the connection of an electric motor 6 in conjunction with its worm wheel 7, which together act on a Mitnehmerrad 5. In fact, in this case, the lever member 2 riveted to the base lever 1 is a driver arm which cooperates with the motor-driven driving wheel 5.

Dazu arbeitet der Elektromotor 6 mit seinem Schneckenrad 7 auf das einen Zahnkranzabschnitt aufweisende Mitnehmerrad 5, welches einen Steuernocken 8 für den Mitnehmerarm 2 aufweist. Bei angetriebenem Mitnehmerrad 5 führt der Auslösehebel 1, 2, 3 eine Schwenkbewegung aus und betätigt die Sperrklinke 4, die entweder in die angedeutete Hauptrast 9 der Drehfalle 10 einfällt oder demgegenüber ausgehoben wird.For this purpose, the electric motor 6 works with its worm wheel 7 on the one sprocket portion having Mitnehmerrad 5, which has a control cam 8 for the driving arm 2. When driven Mitnehmerrad 5 of the trigger lever 1, 2, 3 performs a pivoting movement and actuates the pawl 4, which either occurs in the indicated main catch 9 of the rotary latch 10 or is lifted in contrast.

Das weitere Hebelglied 3 ist als Betätigungsarm ausgeführt und bildet eine Baueinheit mit dem Basishebel 1. Insoweit ist der Betätigungshebel 3 bzw. Betätigungsarm beispielsweise mit einem Innen- oder Außenbetätigungshebel oder auch einem Zentralverriegelungselement verbunden. Das gesamte Hebelwerk aus Basishebel 1 sowie den Hebelgliedern 2, 3 kann aus Metall, Kunststoff oder einer Kombination beider vorgenannten Werkstoffe bestehen.The further lever member 3 is designed as an actuating arm and forms a structural unit with the base lever 1. In that regard, the operating lever 3 or actuator arm, for example, connected to an internal or external operating lever or a central locking element. The entire lever mechanism of the base lever 1 and the lever members 2, 3 may be made of metal, plastic or a combination of both aforementioned materials.

Im Rahmen der mechanischen Variante nach Fig. 1 mit dem Auslösehebel 1, 3, bestehend aus dem Basishebel 1 und dem Betätigungshebel bzw. Betätigungsarm 3, wird die Verschwenkung des Auslösehebels 1, 3 mechanisch bewerkstelligt. Dazu verfügt der Auslösehebel 1, 3 bzw. der Basishebel 1 über eine Ausnehmung bzw. Bohrung 11, in die ein Verbindungselement 12 eingreift. Mit Hilfe des Verbindungselementes 12, welches als Bowdenzug, Stange etc. ausgeführt sein kann, lässt sich der Auslösehebel 1, 3 bei der mechanischen Version manuell im Gegenuhrzeigersinn beim Übergang von der Fig. 1 zur Fig. 2 um seine Achse 13 verschwenken, so dass infolgedessen die hiermit zusammenwirkende Sperrklinke 4 in Bezug auf die Drehfalle 10 ausgehoben wird. Wie gesagt, fehlt in diesem Fall einer mechanischen Betätigung des Auslösehebels 1, 3 das Hebelglied 2 bzw. der Hebelarm 2.Within the scope of the mechanical variant Fig. 1 with the release lever 1, 3, consisting of the base lever 1 and the actuating lever or actuating arm 3, the pivoting of the trigger lever 1, 3 is accomplished mechanically. For this purpose, the release lever 1, 3 or the base lever 1 via a recess or bore 11 into which a connecting element 12 engages. With the help of the connecting element 12, which may be designed as a Bowden cable, rod, etc., the release lever 1, 3 in the mechanical version can be manually counterclockwise when passing from the Fig. 1 to Fig. 2 pivot about its axis 13, so that consequently the pawl 4 cooperating therewith in relation to the rotary latch 10 is excavated. As I said, one is missing in this case mechanical actuation of the release lever 1, 3, the lever member 2 and the lever arm. 2

Erfindungsgemäß ist es nun möglich, unter Rückgriff auf den gleichen Basishebel 1 (sowie das übereinstimmende Hebelglied 3) die dargestellte Version aufzurüsten, in dem nun ein elektrisches Öffnen des Gesperres 4, 10 aus Sperrklinke 4 und Drehfalle 10 möglich wird. Dazu geht das Hebelglied 2 bzw. der Mitnehmerarm die bereits beschriebene Verbindung mit dem Basishebel 1 ein, bei welcher es sich vorliegend um eine Nietverbindung entsprechend der Fig. 2 handelt. Grundsätzlich sind zur Kopplung des Hebelarmes 2 mit dem Basishebel 1 aber auch andere Verbindungsmöglichkeiten denkbar und vom Erfindungsgedanken umfasst, so z. B. eine Rast-, Schraub-, oder auch AdhäsivverbindungAccording to the invention it is now possible, using the same base lever 1 (and the matching lever member 3) to upgrade the version shown, in which now an electrical opening of the locking mechanism 4, 10 of pawl 4 and rotary latch 10 is possible. For this purpose, the lever member 2 and the driving arm, the already described connection with the base lever 1, in which there is a rivet connection according to the present Fig. 2 is. Basically, for the coupling of the lever arm 2 with the base lever 1 but also other connection options are conceivable and includes the concept of the invention, such. B. a locking, screw, or adhesive connection

In jedem Fall besteht die Möglichkeit, das Hebelwerk mit dem Basishebel 1, der Sperrklinke 4 und der Drehfalle 10 im Schlosskasten zu realisieren, und zwar ungeachtet dessen, welche Funktionen der Kraftfahrzeugtürverschluss letztendlich ausführen soll. Je nach Kundenwunsch lässt sich dann diese Grundversion mit dem weiteren Hebelglied 3 als Betätigungsarm ausrüsten, um beispielsweise eine Öffnung des Gesperres 4, 2 mit Hilfe eines Außenbetätigungshebels oder auch Innenbetätigungshebels mechanisch gewährleisten zu können.In any case, it is possible to realize the lever mechanism with the base lever 1, the pawl 4 and the rotary latch 10 in the lock case, regardless of which functions the motor vehicle door lock is ultimately intended to perform. Depending on customer requirements, this basic version can then be equipped with the further lever member 3 as an actuating arm in order to be able to mechanically ensure, for example, an opening of the locking mechanism 4, 2 with the aid of an external actuating lever or also an internal actuating lever.

Fehlt an dieser Stelle beispielsweise ein Außenbetätigungshebel, weil insofern die zugehörige Kraftfahrzeugtür grifflos gestaltet ist, kann auf das betreffende Hebelglied 3 verzichtet werden. Dann wird man regelmäßig lediglich den Innenbetätigungshebel über das Verbindungselement 12 und die Bohrung 11 auf den Basishebel 1 arbeiten lassen. Wird in diesem Fall zusätzlich noch eine elektromotorische Öffnung gewünscht, so wird das Hebelglied 2 an den Basishebel 1 angeschlossen und werden im Übrigen der Elektromotor 6, das Schneckenrad 7 und das Mitnehmerrad 5 mit dem Steuernocken 8 im Schlosskasten platziert.Missing at this point, for example, an external operating lever, because insofar as the associated motor vehicle door is designed handleless, can be dispensed with the relevant lever member 3. Then you will regularly only the Inner operating lever via the connecting element 12 and the bore 11 to work on the base lever 1. If an electromotive opening is additionally desired in this case, then the lever member 2 is connected to the base lever 1 and, moreover, the electric motor 6, the worm wheel 7 and the driving wheel 5 with the control cam 8 are placed in the lock case.

Im Rahmen des Ausführungsbeispiels nach Fig. 3 ist der Mitnehmerarm 2 als separates Hebelglied ausgeführt, welcher mit dem aus Basishebel 1 und Hebelglied 3 zusammengesetzten Auslösehebel 1, 3 auf einer Achse 13 verschwenkbar gelagert. ist. Der Mitnehmerarm 2 verfügt über einen Anschlag 14, welcher mit einer vorzugsweise ebenen Kontur 15 des Auslösehebels 1, 3 korrespondiert, so dass aus Auslösehebel 1, 3 und Mitnehmerarm 2 ein formschlüssiger Verbund entsteht. Der Verbund aus Mitnehmerarm 2 und Auslösehebel 1, 3 bilden so den Mehrfunktionshebel 1, 2, 3, der über das elektromotorisch angetriebene Mitnehmerrad 5 bzw. den Steuernocken 8 verschwenkt werden kann.In the context of the embodiment according to Fig. 3 the driver arm 2 is designed as a separate lever member, which is pivotably mounted on an axis 13 with the release lever 1, 3 composed of base lever 1 and lever member 3. is. The driving arm 2 has a stop 14, which corresponds to a preferably flat contour 15 of the release lever 1, 3, so that from release lever 1, 3 and driving arm 2, a positive connection is formed. The composite of Mitnehmerarm 2 and tripping lever 1, 3 thus form the multi-function lever 1, 2, 3, which can be pivoted about the electric motor driven Mitnehmerrad 5 and the control cam 8.

In jedem Fall führt ein Verschwenken des Mitnehmerarms 2 des Mehrfunktionshebels 1, 2, 3 im Gegenuhrzeigersinn beim Übergang von der Fig. 3 zur Fig. 2 dazu, dass die Sperrklinke 4 in Bezug auf die Drehfalle 10 aus der Hauptrast 9 ausgehoben wird.In any case, a pivoting of the Mitnehmerarms 2 of the multi-function lever 1, 2, 3 in the counterclockwise direction in the transition from the Fig. 3 to Fig. 2 in that the pawl 4 is lifted out of the main catch 9 with respect to the catch 10.
