Description

• einem Gesperre,
• einem ersten Hebel,
• einem zweiten Hebel und
• einer Antriebseinheit mit einem z.B. elektromotorischen Antrieb und einem drehbaren Stellglied,

wobei mit dem Antrieb über das Stellglied sowohl der erste Hebel aus einer ersten Funktionsstellung in eine zweite Funktionsstellung als auch der zweite Hebel aus einer ersten Funktionsstellung in eine zweite Funktionsstellung überführbar ist und umgekehrt. Erster Hebel und zweiter Hebel meint ganz allgemein verschiedene Hebel innerhalb eines Kraftfahrzeugtürverschlusses. Bei dem ersten Hebel kann es sich beispielsweise um einen Zentralverriegelungshebel und bei dem zweiten Hebel um einen Diebstahlsicherungshebel handeln. Ferner kann es sich bei den Hebeln um solche für das elektrische Öffnen der Drehfalle und das elektrische Zuziehen der Drehfalle handeln. Erster und/oder zweiter Hebel können auch als Kindersicherungshebel oder als Hebel für die Betätigung eines Nebenschlosses ausgebildet sein. Stets sind mit erstem Hebel und zweitem Hebel zwei Hebel eines Kraftfahrzeugtürverschlusses gemeint, welche zwei (unterschiedliche) Schlossfunktionen betätigen. Ein Gesperre besteht üblicherweise aus einer Drehfalle und einer auf die Drehfalle wirkenden Sperrklinke. Verriegelungshebel und Diebstahlsicherungshebel wirken in einem solchen Kraftfahrzeugtürverschluss in an sich bekannter Weise mit einer entsprechenden Verriegelungsmechanik und/oder Betätigungsmechanik derart zusammen, dass der Verriegelungshebel in der Position entriegelt eine entsprechende Kraftwirkungskette (z. B. Innenbetätigungskette und Außenbetätigungskette) freigibt und in der verriegelten Position blockiert oder einen Leerhub erzeugt. Während der Verriegelungshebel, z.B. in der Ausführungsform als Zentralverriegelungshebel üblicherweise eine Außenbetätigungskette unterbricht, wirkt der Diebstahisicherungshebel üblicherweise sowohl auf die Außenbetätigungskette als auch auf eine Innenbetätigungskette, so dass der Kraftfahrzeugtürverschluss in der diebstahlgesicherten Funktionsstellung auch über einen Innenverriegelungshebel oder einen Innenbetätigungshebel nicht entriegelbar ist.The invention relates to a motor vehicle door lock with at least

• a locking mechanism,
• a first lever,
• a second lever and
• a drive unit with an eg electromotive drive and a rotatable actuator,

wherein with the drive via the actuator both the first lever from a first functional position to a second functional position and the second lever from a first functional position can be converted into a second functional position and vice versa. First lever and second lever generally means different levers within a motor vehicle door latch. For example, the first lever may be a central locking lever and the second lever may be an anti-theft lever. Furthermore, the levers may be those for the electrical opening of the rotary latch and the electrical tightening of the rotary latch. First and / or second lever can also be designed as a child safety lever or as a lever for the operation of a secondary lock. Always means with the first lever and second lever two levers of a motor vehicle door lock, which operate two (different) lock functions. A locking mechanism usually consists of a rotary latch and a pawl acting on the rotary latch. Locking lever and anti-theft lever act in such a motor vehicle door lock in a conventional manner with a corresponding locking mechanism and / or operating mechanism such together that the locking lever in the unlocked position releases a corresponding force action chain (eg, inner idler chain and outer idler chain) and blocks in the locked position or creates a deadlift. While the lock lever, for example, in the embodiment as the central lock lever usually interrupts an external operation chain, the theft prevention lever usually acts on both the outside operation chain and an inside operation chain, so that the vehicle door lock can not be unlocked in the theft-proof operation position even by an inside lock lever or an inside operation lever.

Motor vehicle door locks of the type described above are known in various embodiments. From the DE 43 43 340 A1 One knows such a motor vehicle door lock, in which a single electric motor drive operates on both a central locking lever and an anti-theft lever. For this purpose, an output element with eccentric control pin is connected to the reversible electric motor, which engages on the one hand in a fork seat of the central locking lever and on the other hand works on a corresponding control surface on the anti-theft lever. Such motor vehicle door locks have proven themselves in principle. They are, however, capable of further development.

The invention has for its object to provide a motor vehicle door lock of the type described above, which can perform two castle functions with a single drive in a simple and reliable manner and which is constructed at the same time simple and inexpensive.

To solve this technical problem, the invention teaches in a generic motor vehicle door lock of the type described above, that the first lever and the second lever via a clutch lever with each other are connected. In this case, the second lever via the clutch lever with the actuator of the drive unit can be coupled or coupled. In the context of the invention, a perfect and reliable actuation or manipulation of a plurality of levers of a motor vehicle door lock thus succeeds with a single electromotive drive. The coupling between the first lever and the second lever via the clutch lever, which at the same time couples the second lever to the actuator, ensures trouble-free operation in a structurally simple and cost-effective manner via a single drive, eg a single electric motor.

The clutch lever is preferably pivotally and slidably connected to the first lever and / or to the second lever and / or to the actuator. According to a particularly preferred embodiment of the invention, the clutch lever is acted upon or acted upon by at least one clutch spring, which z. B. is connected to the first lever.

The drive unit preferably has a rotatable adjusting disk (or a setting wheel) as an actuator, wherein the adjusting disk has at least a first control receptacle for the first lever and a second control receptacle for the second lever and / or the coupling lever in the course of rotation of the adjusting disk over the electromotive The first lever for transferring from the first functional position into the second functional position (or vice versa) can therefore be pivoted on the one hand because the first lever engages in a corresponding control receptacle of the adjusting disc or is connected to such a control receptacle. In addition, the second lever can be transferred from the first functional position to the second functional position (or vice versa) by rotation of the adjusting disc via the electromotive drive, since the second lever, for. B. with the interposition of the coupling lever, engages in the second control receptacle of the adjusting disc or connected to the second control receptacle.

Furthermore, the invention proposes that the rotatable adjusting disc is designed as a spring-loaded adjusting disc, which is traceable by means of a return spring in a basic position after actuation by the drive. This configuration of the adjusting disc with application of a "center-zero spring" makes it possible to perform the two actuating operations of the two levers not only with one and the same electric motor drive and one and the same adjusting disc, but also with an identical operating rotation of the same basic position in the same direction , possibly even over the same angle of rotation.

Thus, the invention proposes according to a very preferred embodiment, that the adjusting disc transferred by a first actuation from a basic position in a predetermined first rotational direction over a predetermined rotation angle, the first lever from the first functional position to the second functional position, wherein the adjusting disc after the first actuation via the return spring is returned to the home position and that subsequently by a second actuation again from the basic position in preferably the same first rotational direction of the second lever is transferred from the first functional position to the second functional position. This succeeds in particular because the clutch lever is preferably biased in the course of the first actuation of the first lever or in the course of pivoting of the first lever via the clutch spring. Subsequently, the clutch spring transfers the clutch lever after returning the adjusting disk in the basic position in an activated functional position coupling the second lever with the adjusting disk, wherein the second lever in this activated functional position of the coupling lever in the course of a second operation in the second functional position can be transferred. Accordingly, the spring-loaded clutch lever allows the operation of the first lever and the second lever successively with identical operating rotation in the same direction and possibly also with the same angle of rotation. The return The center-zero spring also ensures, taking into account appropriate control recordings in the adjusting disc, that not only an electromechanical actuation, but also a manual actuation in the event of failure of the drive is possible.

Of course, it is possible to convert the reversible motor by actuation of the actuator in the opposite direction of rotation, both the first lever in its first operating position and the second lever in its first functional position. The activation of the clutch lever after the operation of the first lever takes place automatically via the clutch spring.

According to another proposal of the invention, the second control receptacle in the adjusting disk as a recess, z. B. slot guide, formed, in which a (connected to the second lever) coupling pin or the like coupling element of the coupling lever engages. The first shot in the adjusting disc can also be used as a recess, for. B. as edge-side adjusting recess, be formed, in which engages an actuating pin or the like actuating element of the first lever. The first control receptacle and second control receptacle can be arranged on different radii of the adjusting disc and / or in different "angular ranges" of the adjusting disc. Overall, an arrangement of the first lever on the one hand and the second lever on the other hand succeeds without overlap or overlaps, so that a particularly compact and reliable construction is ensured.

The clutch lever can z. B. have a connection pin or the like, which in a recess, for. B. engages a slot guide of the first lever. In the region of this recess then preferably also the clutch spring is arranged, that is, the clutch spring moves the Connecting pin of the coupling lever in the slot guide or the coupling pin biases the clutch spring in the course of movement through the slot guide.

In one embodiment of the invention, the first lever as a locking lever, z. B. central locking lever, whose first functional position "unlocks" the position and the second functional position is the position "locked". The second lever may be formed as an anti-theft lever, the first functional position of the position "theft-proof" and the second functional position is the position "theft-proof". However, first lever and second lever can also be other levers, which fulfill two different lock functions, eg. B. in connection with the opening of the catch, with the closing of the catch, with a child safety lock or with an operation of a secondary lock.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A motor vehicle door lock 1 for a motor vehicle 2 is shown in detail in the figures, comprising a locking catch and a pawl acting on the rotary latch, a first lever designed as a locking lever 3, a second lever designed as a theft prevention lever 4, and a drive unit 5 having. Furthermore, such a motor vehicle door lock 1 in a conventional manner corresponding force action chains for an internal operation and / or an external operation and an internal lock and an external lock on. This is not shown in detail. The locking lever 3 is usually designed as a central locking lever 3, which is actuated via the drive unit 5. The drive unit 5 has an electric motor drive 6 and a rotatable actuator 7, wherein the drive motor 6 via a gear unit 8, z. B. a screw or the like works on the actuator 7.

In the context of the invention is now with a single electric motor drive 6 via the rotatable actuator 7, both the locking lever 3 from a first functional position "unlocked" in a second functional position "locked" and the theft prevention lever 4 from a first functional position "theft-proof" in a second Function position "theft-proof" convertible and vice versa.

To ensure this in a structurally simple and reliable manner, the locking lever 3 and the anti-theft lever 4 are connected to each other via a clutch lever 9. This means that the anti-theft locking lever 4 can be coupled to the actuator 7 of the drive unit 5 via the clutch lever 9. The clutch lever 9 is acted upon by a clutch spring 19, which is connected to the locking lever 3. For this purpose, an arcuate slot guide 20 is arranged in the locking lever, in which the spring 19, the pin 12 is applied.

The figures show that the central locking lever 3 as about a pivot axis 10 pivotable lever and the anti-theft lever 4 are also designed as pivotable about a pivot axis 11, wherein both the anti-theft lever 4 and the central locking lever 3 with z. B. their end portions in the range of action of the actuator 7 protrude. Between the anti-theft lever 4 and the central locking lever 3, the clutch lever 9 is held without further articulation on the motor vehicle door lock 1. The clutch lever 9 is therefore not itself hinged to a housing o. The like. In this case, the clutch lever 9 is initially pivotally and slidably connected to the locking lever 3. For this purpose, the clutch lever 9 engages with an end-side pin 12 in a slot guide 20 in the central locking lever 3 a. With its opposite end of the clutch lever 9 engages a second pin 13 in a slot recess 14 of the anti-theft lever 4 a. In addition, the clutch lever 9 engages with this coupling pin 13 in a theft prevention lever 4 associated control receptacle 16 of the actuator 7, so that via the clutch lever 9 of the anti-theft lever 4 with the actuator 7 of the drive unit 5 can be coupled.

The actuator 7 is designed as a rotatable adjusting disk 7, wherein this adjusting disk 7 a first control receptacle 15 for the central locking lever. 3 and a second control receptacle 16 for the anti-theft lever 4 and the clutch lever 9 has. Further, it is indicated that the rotatable adjusting disc 7 is formed as a spring-loaded adjusting disc, which is held by a return spring 17 in the sense of a "center-zero spring" in a basic position or is returned to the successful operation by the drive 6 in such a basic position , This basic position is in Fig. 2 shown. The figures also show that the second control receptacle 16 in the adjusting disc 7 as a recess, namely as (arcuate) slot guide 16, is formed, in which the coupling pin 13 of the coupling lever 9 engages. This slot guide 16 is formed in the embodiment as a Z-shaped slot guide or step-like slot guide with two arranged on different radii arcuate guide areas. The first control receptacle 15 in the adjusting disc is formed as an "open" edge-side adjusting recess 15, in which an actuating pin 18 of the locking lever 3 engages.

Of particular importance is now in the context of the invention that the adjusting disc 7 transferred by a first operation from a basic position in a predetermined first rotational direction A over a predetermined angle of rotation, the locking lever 3 from the position "unlocked" in the position "locked", wherein the Adjusting disk 7 is returned to the initial position after the first actuation via the return spring 17 and that then transferred by a second operation from the basic position in the same first direction of rotation A theft prevention lever 4 from the position "unlocked" in the position "secured". The clutch lever 9 is pretensioned in the course of the first operation of the locking lever 3 via the clutch spring 19. Thus, the clutch spring 19 transfers the clutch lever 19 after returning the adjusting disk 7 in the basic position in an anti-theft lever 4 and the adjusting disc 7 "activated functional position", wherein the anti-theft lever 4 in this activated functional position of the clutch lever 9 in the course of a second operation in the functional position "secured" can be transferred.

• Fig. 2 zeigt die Anordnung zunächst einmal in einer "Grundausgangsposition", in welcher der Zentralverriegelungshebel 3 sich in der Position "entriegelt"und der Diebstahlsicherungshebel 4 in der Position "entsichert" befinden. Die Stellscheibe 7 befindet sich in der über die Feder 17 zurückgeführten Grundposition. Zum Zwecke der Verriegelung wird nun der reversierbare elektromotorische Antrieb 6 bestromt und die Stellscheibe 7 in der ersten Drehrichtung A (gegen den Uhrzeigersinn) gedreht. Eine vergleichende Betrachtung der Fig. 2 und 3 zeigt, dass im Zuge dieser ersten Betätigung eine erste Steuerkante a der Steuerausnehmung 15 auf den Zentralverriegelungshebel 3 bzw. dessen endseitigen Zapfen 18 arbeitet und folglich den Zentralverriegelungshebel 3 im Uhrzeigersinn um die Schwenkachse 10 verschwenkt und ihn so in die Funktionsstellung "verriegelt" überführt. In dieser Funktionsstellung des Zentralverriegelungshebels 3 wird üblicherweise die entsprechende Kraftwirkungskette, z. B. Außenbetätigungskette unterbrochen bzw. blockiert. Dieses ist nicht im Detail dargestellt. In Fig. 3 ist ferner erkennbar, dass der Diebstahlsicherungshebel 4 seine Position im Zuge der ersten Betätigung nicht verändert, da der Kupplungszapfen 13, welcher den Diebstahlsicherungshebel 4 durchgreift, in der zugeordneten Langlochführung 16 freibewegt werden kann. Fig. 3 zeigt jedoch, dass durch Verschwenken des Zentralverriegelungshebels 3 zugleich die Kupplungsfeder 19 von dem Kupplungshebel 9 innerhalb der Langlochführung 20 vorgespannt wird. Durch die Zwangsführung des Kupplungshebels 9 in der zugeordneten Führung 16 der Stellscheibe 7 verbleibt der Kupplungshebel 9 jedoch im Wesentlichen in seiner Ausgangsposition. Nach erfolgter Verriegelung gelangt die Stellscheibe 7 über die Rückstellfeder 17 automatisch in ihre Grundposition (vgl. Fig. 4). In dieser Grundposition kann nun die vorgespannte Kupplungsfeder 19 den Kupplungshebel 9 in der dargestellten Weise innerhalb des Langloches 14 des Diebstahlsicherungshebels 4 verschieben, so dass nun über den Kupplungshebel 9 bzw. dessen Kupplungszapfen 13 der Diebstahlsicherungshebel 4 mit der Stellscheibe 7 gekoppelt und folglich die Diebstahlsicherung gleichsam aktiviert wird. Insofern zeigt Fig. 4 eine Funktionsstellung des Diebstahlsicherungshebels 4, in der der Diebstahlsicherungshebel zwar nach wie vor entsichert, jedoch "aktiviert" ist. Ausgehend von dieser Grundposition der Stellscheibe in Fig. 4 kann nun durch erneute Bestromung des Elektromotors 6 die Stellscheibe nochmals in exakt derselben ersten Drehrichtung A (gegen den Uhrzeigersinn) gedreht werden. Da sich der Verriegelungshebel 3 bereits in der verriegelten Position befindet, erfolgt nun keine Manipulation des Verriegelungshebels 3 mehr. Eine vergleichende Betrachtung der Fig. 4 und 5 macht jedoch deutlich, dass nun der den Diebstahlsicherungshebel 4 durchgreifende Kupplungszapfen 13 gegen die zugeordnete Steuerkante b der Langlochführung 16 in der Stellscheibe 7 anliegt, so dass der Diebstahlsicherungshebel 4 gemäß Fig. 5 im Zuge der Drehung der Stellscheibe 7 um die Schwenkachse 11 im Uhrzeigersinn verschwenkt wird. Fig. 5 zeigt daher eine Funktionsstellung, bei der sich der Verriegelungshebel 3 in der Position verriegelt und der Diebstahlsicherungshebel 4 in der Position gesichert befindet. Nun kann über die Rückstellfeder 17 die Stellscheibe 7 wieder in ihre Grundposition gelangen. Dieses ergibt sich aus einer vergleichenden Betrachtung der Fig. 5 und 6.

The mode of operation of the motor vehicle door lock 1 according to the invention will now be described with reference to FIG Fig. 2 to 7 be explained:

• Fig. 2 shows the arrangement first of all in a "basic starting position" in which the central locking lever 3 is in the "unlocked" position and the anti-theft lever 4 in the "unlocked" position. The adjusting disc 7 is located in the returned via the spring 17 basic position. For the purpose of locking the reversible electromotive drive 6 is now energized and the adjusting disc 7 in the first direction of rotation A (counterclockwise) rotated. A comparative analysis of the FIGS. 2 and 3 shows that in the course of this first operation, a first control edge a of the control recess 15 on the central locking lever 3 and its end-side pin 18 operates and thus pivots the central locking lever 3 in a clockwise direction about the pivot axis 10 and so "locked" in the functional position. In this functional position of the central locking lever 3 is usually the corresponding force action chain, z. B. external actuating chain interrupted or blocked. This is not shown in detail. In Fig. 3 is also seen that the anti-theft lever 4 does not change its position in the course of the first operation, since the coupling pin 13, which passes through the anti-theft lever 4, can be moved in the associated slot guide 16. Fig. 3 However, shows that by pivoting the central locking lever 3 at the same time the clutch spring 19 is biased by the clutch lever 9 within the slot guide 20. Due to the positive guidance of the clutch lever 9 in the associated guide 16 of the adjusting disc 7, the clutch lever 9, however, remains essentially in its starting position. After locking, the adjusting disk 7 automatically passes over the return spring 17 in their Basic position (cf. Fig. 4 ). In this basic position, the preloaded clutch spring 19 can now move the clutch lever 9 in the manner shown within the slot 14 of the anti-theft lever 4, so that now coupled via the clutch lever 9 and the coupling pin 13 of the anti-theft lever 4 with the adjusting disc 7 and thus theft protection as it were is activated. In this respect shows Fig. 4 a functional position of the anti-theft lever 4, in which the anti-theft lever is still unlocked, but "activated" is. Starting from this basic position of the adjusting disk in Fig. 4 can now by re-energizing the electric motor 6, the adjusting disc again in exactly the same first rotational direction A (counterclockwise) are rotated. Since the locking lever 3 is already in the locked position, there is now no manipulation of the locking lever 3 more. A comparative analysis of the 4 and 5 However, it makes it clear that now the anti-theft lock lever 4 by cross-coupling pin 13 rests against the associated control edge b of the slot guide 16 in the adjusting disc 7, so that the anti-theft lever 4 according to Fig. 5 in the course of rotation of the adjusting disc 7 is pivoted about the pivot axis 11 in the clockwise direction. Fig. 5 shows therefore a functional position in which the locking lever 3 is locked in position and the anti-theft lever 4 is secured in position. Now, the adjusting disk 7 can return to its basic position via the return spring 17. This results from a comparative analysis of the Fig. 5 and 6 ,

A comparative analysis of the 6 and 7 makes it clear that now by an operation or rotation of the adjusting disc 7 in the opposite direction B, namely clockwise in a single operation, both the locking lever 3 unlocked and the anti-theft lever 4 can be interpreted. For the respectively associated control edges c, d of the second control recess 16 and the first control recess 15 engage now at the associated pin 18 on the locking lever 3 and the coupling pin 13, which also passes through the anti-theft lever 4, to. About the return spring 17, the adjusting disk 7 then passes from the in Fig. 7 position shown in the already in Fig. 2 illustrated starting position.

In principle, it is also possible to jump directly from the functional position Fig. 4 to transfer the locking lever 3 again in the unlocked position, namely in the starting from Fig. 4 the adjusting disk 7 is moved in the opposite direction of rotation B (clockwise), so that then not as in Fig. 5 indicated in the theft-proof position, but as in Fig. 7 indicated, would get into the unlocked and unlocked position.
