Die Erfindung betrifft eine Türschlossbaugruppe für ein Kraftfahrzeug, insbesondere für eine Seitentür oder Heckklappe, aufweisend ein Gehäuse, in welchem eineThe invention relates to a door lock assembly for a motor vehicle, in particular for a side door or tailgate, comprising a housing in which a

Drehfalle und eine Sperrklinke angeordnet ist, die mit einem Mitnehmer mechanisch verbunden ist, wobei die Sperrklinke und der Mitnehmer relativ zueinander bewegbar ausgebildet sind und der Mitnehmer, insbesondere bei einem Öffnungsvorgang, über ein Antriebselement mittels eines Elektromotors bewegbar ist.Rotary latch and a pawl is arranged, which is mechanically connected to a driver, wherein the pawl and the driver are designed to be movable relative to each other and the driver, in particular during an opening operation, via a drive element by means of an electric motor is movable.

Aus dem Stand der Technik ist die deutsche Offenlegungsschrift DE102007024672A1 bekannt, die eine Türschlossbaugruppe mit einem Gehäuse offenbart. Die Türschlossbaugruppe weist einen Mitnehmer und eine Sperrklinke auf, wobei die Sperrklinke über dem Mitnehmer drehbar gelagert angeordnet ist. Häufig ist es der Fall, dass bei Kraftfahrzeugen zur Aufnahme von Schlossbaugruppen innerhalb der Seitentüren, Heckklappen und dergleichen nur Bauräume mit geringen Abmaßen zur Verfügung gestellt werden. In diesen Fällen ist ein Einbau der aus dem Stand der Technik bekannten Türschlossbaugruppe nur bedingt möglich.The German Offenlegungsschrift is known from the prior art DE102007024672A1 which discloses a door lock assembly having a housing. The door lock assembly has a driver and a pawl, wherein the pawl is rotatably mounted on the driver. It is often the case that in motor vehicles for receiving lock assemblies within the side doors, tailgates and the like, only installation spaces with small dimensions are provided. In these cases, installation of the door lock assembly known from the prior art is only possible to a limited extent.

Die FR2768761A1 offenbart eine Türschlossbaugruppe, bei welcher der Mitnebmer auf der Sperrklinke angeordnet ist.The FR2768761A1 discloses a door lock assembly in which the rider is located on the pawl.

Daher ist es die Aufgabe der Erfindung, eine konstruktiv einfache und kompakte Türschlossbaugruppe bereitzustellen.It is therefore the object of the invention to provide a structurally simple and compact door lock assembly.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Mitnehmer eine Ausnehmung aufweist, die zur Aufnahme der Sperrklinke dient. Durch diese vorteilhafte Ausgestaltung ist es möglich, die Gehäuseabmaße zu verringern. Die Höhe des Gehäuses wird mindestens um den Betrag der Höhe der Sperrklinke verringert. Somit ist sichergestellt, dass auch bei kleineren in den Seitentüren oder Heckklappen zur Verfügung stehenden Bauräumen eine zuverlässige, kostengünstige und kompakte Türschlossbaugruppe eingesetzt werden kann. Ebenfalls wird durch geringere Gehäuseabmaße das Gewicht der Türschlossbaugruppe reduziert. Ferner wird weniger Material für das meist aus Edelstahl oder Kunststoff ausgebildete Gehäuse der Türschlössbaugruppe benötigt, wenn dieses kompakter aufgebaut ist.The object is achieved in that the driver has a recess which serves to receive the pawl. This advantageous embodiment, it is possible to reduce the housing dimensions. The height of the housing is reduced by at least the amount of the height of the pawl. This ensures that a reliable, cost-effective and compact door lock assembly can be used even with smaller installation spaces available in the side doors or tailgates. Also, smaller housing dimensions reduce the weight of the door lock assembly. Furthermore, less material is required for the usually made of stainless steel or plastic housing of the door lock assembly, if this is constructed more compact.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Ausnehmung durch mindestens zwei, insbesondere zueinander parallel, angeordnete Stege des Mitnehmers gebildet wird, wobei die Stege aus einem Basisabschnitt des Mitnehmers herausragen. Durch diese Maßnahme gelingt es, mit einfachen konstruktiven Mitteln eine Ausnehmung bereitzustellen, welche für eine Aufnahme einer Sperrklinke geeignet ist. Die zwei zueinander angeordneten parallel angeordneten Stege sorgen für eine stabile Lagerung der Sperrklinke innerhalb des Mitnehmers.According to a further embodiment of the invention it is provided that the recess is formed by at least two, in particular parallel to each other, arranged webs of the driver, wherein the webs protrude from a base portion of the driver. By this measure, it is possible to provide a recess with simple structural means, which is suitable for receiving a pawl. The two mutually parallel arranged webs ensure stable storage of the pawl within the driver.

Nach einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Stege durch eine erste Wand miteinander verbunden sind, welche als Anschlag für die Sperrklinke dient. Beim Schließvorgang wird somit in vorteilhafterweise der Mitnehmer von der Sperrklinke mitgenommen, so dass auf einen elektrische Antrieb verzichtet werden kann, um den Mitnehmer zu bewegen.According to a preferred embodiment of the invention it is provided that the webs are connected by a first wall, which serves as a stop for the pawl. During the closing process, the driver is thus advantageously carried along by the pawl, so that an electric drive can be dispensed with in order to move the driver.

Nach einer nächsten bevorzugten Ausführungsform ist vorgesehen, dass die Stege durch eine zweite Wand miteinander verbunden sind, welche als Lager zur Abstützung der Stege dient. Aufgrund dieser Weiterbildung wird die Lagerung der einzelnen Stege zueinander verbessert, so dass eine noch stabilere Aufnahme der Sperrklinke in dem Mitnehmer gewährleistet wird.According to a next preferred embodiment it is provided that the webs are connected by a second wall, which serves as a bearing for supporting the webs. Due to this development, the storage of the individual webs is improved to each other, so that an even more stable recording of the pawl is ensured in the driver.

Bei einer weiteren vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, dass jeder Steg jeweils eine Öffnung aufweist, die zur schwenkbaren Lagerung des Mitnehmers dient. Der wesentliche Vorteil besteht darin, dass die Öffnungen mit einfachen Mitteln kostengünstig hergestellt werden können. Beispielsweise können die Öffnungen nachträglich ausgestanzt werden, oder es werden bereits im Formwerkzeug entsprechende Schieber zur Herstellung der Öffnungen bereitgestellt.In a further advantageous embodiment of the object of the invention it is provided that each web has in each case an opening which serves for the pivotable mounting of the driver. The main advantage is that the openings can be made inexpensively by simple means. For example, the openings can be punched out later, or there are already provided in the mold corresponding slide for producing the openings.

Sehr einfach und kostengünstig ist der konstruktive Aufbau, wenn die Sperrklinke eine Öffnung aufweist, die zur schwenkbaren Lagerung der Sperrklinke dient.Very simple and inexpensive is the structural design, when the pawl has an opening which serves for the pivotable mounting of the pawl.

Nach einer vorteilhaften Weiterbildung des Gegenstands der Erfindung ist vorgesehen, dass eine Oberflächenebene des Betätigungsabschnitt und eine Oberflächenebene des Basisabschnitt in einem Winkel a, von vorzugsweise 45°, zueinander angeordnet sind. Durch diese Maßnahme gelingt es, die Schlossbaugruppe mit einem kompakten Gehäuse zu versehen, in welchem gleichzeitig ein elektrischer Antrieb des Türschlosses angeordnet werden kann. Insbesondere bei einem Winkel α von 40° bis 50°, vorzugsweise 45° ist die Gehäusehöhe ausreichend, um die Türschlossbaugruppe auch bei kleineren zur Verfügung stehenden Bauräumen in der Seitentür oder Heckklappe einzusetzen. Der Bauraum wird meist durch die Kontur, insbesondere durch die Außenkontur der Heckklappe oder Seitentür vorgegeben, wobei sich der oben genannte Winkelbereich als vorteilhaft herausgestellt hat.According to an advantageous development of the subject of the invention, it is provided that a surface plane of the actuating portion and a surface plane of the base portion at an angle a, preferably of 45 °, are arranged to each other. By this measure, it is possible to provide the lock assembly with a compact housing, in which at the same time an electric drive of the door lock can be arranged. In particular, at an angle α of 40 ° to 50 °, preferably 45 °, the housing height is sufficient to use the door lock assembly even with smaller available space in the side door or tailgate. The space is usually given by the contour, in particular by the outer contour of the tailgate or side door, with the above-mentioned angle range has been found to be advantageous.

Nach einer nächsten bevorzugten Ausführungsform ist vorgesehen, dass der Mitnehmer aus Kunststoff ausgebildet ist. Die Verwendung von Kunststoff ist bei der erfindungsgemäßen Türschlossgruppe von großem Vorteil, weil zum Einem das Gewicht der Türschlossbaugruppe verringert wird, und zum Anderem die Geräusche beim Anschlag des Mitnehmers an das Dämpfungselement verringert werden.According to a next preferred embodiment, it is provided that the driver is made of plastic.

Die Sperrklinke 8 ist mit einem Mitnehmer 13 mechanisch verbunden, wobei die Sperrklinke 8 und der Mitnehmer 13 relativ zueinander bewegbar ausgebildet sind. Der Mitnehmer 13 wird, insbesondere bei einem Öffnungsvorgang des Türschlosses über ein Antriebselement 14, welches im vorliegenden Fall als Antriebsscheibe mit einer Steuerkurve ausgebildet ist, mittels eines Elektromotors 15 aufweisend einen Schneckenantrieb von einer Schließstellung, bei welcher ein am Kraftfahrzeug befestigter Schließbügel 16 von der Drehfalle 7 gefangen ist, in eine Öffnungsstellung (siehe Figur 4) bewegt. Der Mitnehmer 13 weist eine Ausnehmung 17 auf, die in Figur 6 und Figur 7 visualisiert ist. Die Ausnehmung 17 dient zur Aufnahme der Sperrklinke 8. Die Ausnehmung 17 umfasst zwei zueinander parallel angeordnete Stege 18, die aus einem Basisabschnitt 19 des Mitnehmers 13 herausragen. Der Basisabschnitt des Mitnehmers 13 weist ferner einen Vorsprung 61 zur Abstützung an der Drehfalle 7 auf. Die Stege 18 sind durch eine Wand 20 miteinander verbunden, die als Anschlag für die Sperrklinke 8 dient. Die Funktionsweise des Anschlags wird später noch detaillierter beschrieben. Aus Stabilitätsgründen werden die Stege 18 durch eine zweite Wand 21 miteinander verbunden, welche als Lager zur Abstützung der Stege 18 dient. Die Stege 18 weisen jeweils eine Öffnung 22 auf. Die Sperrklinke 8 weist ebenfalls eine nicht näher gezeigte Öffnung auf. Ein mit dem Gehäuse 2 verbundener Dorn 23 durchdringt die Öffnungen 22 der Stege 18 des Mitnehmers 13 und die Öffnung der Sperrklinke 8, so dass die Sperrklinke 8 und der Mitnehmer 13 mechanisch schwenkbar miteinander verbunden sind. Der Dorn 23 dient dementsprechend als Schwenkachse für die Sperrklinke 8 und den Mitnehmer 13, so dass diese relativ zueinander bewegbar ausgebildet sind.The pawl 8 is mechanically connected to a driver 13, wherein the pawl 8 and the driver 13 are designed to be movable relative to each other. The driver 13 is, in particular in an opening operation of the door lock via a drive element 14, which is formed in the present case as a drive pulley with a cam, by means of an electric motor 15 comprising a worm drive from a closed position, in which an attached to the motor vehicle closing bracket 16 of the rotary latch 7 is caught, in an open position (see FIG. 4 ) emotional. The driver 13 has a recess 17 which in FIG. 6 and FIG. 7 is visualized. The recess 17 serves to receive the pawl 8. The recess 17 comprises two mutually parallel webs 18 which protrude from a base portion 19 of the driver 13. The base portion of the driver 13 also has a projection 61 for support on the rotary latch 7. The webs 18 are interconnected by a wall 20 which serves as a stop for the pawl 8. The operation of the stop will be described in more detail later. For stability reasons, the webs 18 are interconnected by a second wall 21, which serves as a bearing for supporting the webs 18. The webs 18 each have an opening 22. The pawl 8 also has an opening not shown in detail. A connected to the housing 2 mandrel 23 penetrates the openings 22 of the webs 18 of the driver 13 and the opening of the pawl 8, so that the pawl 8 and the driver 13 mechanically pivotally connected to each other. The mandrel 23 accordingly serves as a pivot axis for the pawl 8 and the driver 13, so that they are designed to be movable relative to each other.

Der Sperrklinke 8 ist ein als Kraftspeicher ausgebildetes Federelement 25 zugeordnet. Das Federelement 24 ist als Spiralfeder ausgebildet und umfasst einen beweglichen Federschenkel 25 und einen unbeweglichen Federschenkel 26, wobei der spiralförmige Bereich des Federelements 24 den Dorn 23 zumindest teilweise ummantelt. Der unbewegliche Federschenkel 26 stützt sich an einer Wandung des Gehäuses 2 ab, wobei der bewegliche Federschenkel 25 sich an einer Schulter 27 der Sperrklinke 8 abstützt. Die Schulter 27 der Sperrklinke 8 ist in einem Federarmabstützabschnitt 28 angeordnet. Die Sperrklinke 8 selber weist einen Rastabschnitt 8.1 auf, welcher sowohl während des Schließvorgangs als auch während des Öffnungsvorgangs sowie in der Schließstellung und der Öffnungsstellung stets außerhalb der Ausnehmung 17 des Mitnehmers 13 angeordnet ist.The pawl 8 is associated with a designed as a force storage spring element 25.

Der Mitnehmer 13 umfasst weiter einen Nockenabschnitt 29, der beim Schließvorgang ein innerhalb des Gehäuses 2 an der Gehäuseunterschale 3 angeordnetes Dämpfungselement 30 kontaktiert. Das aus einem elastischen Werkstoff, vorzugsweise aus Gummi ausgebildete Dämpfungselement 30 dient hauptsächlich zur Geräuschminimierung und ist zwischen der Drehfalle 7 und der Gehäuseunterschale 3 angeordnet. Das Dämpfungselement 30 weist eine Öffnung 30.1 auf, welche beim Anschlag der Drehfalle 7 elastisch verformt wird. Das beim Anschlag der Drehfalle 7 zusammengestauchte Material des Dämpfungselements 30 wird in Richtung der Öffnung 30.1 verdrängt, so dass sich die Öffnung 30.1 verkleinert.The driver 13 further comprises a cam portion 29 which contacts a damping element 30 arranged within the housing 2 on the housing lower shell 3 during the closing operation. The damping element 30, which is formed from an elastic material, preferably made of rubber, serves primarily to minimize noise and is arranged between the rotary catch 7 and the housing lower shell 3. The damping element 30 has an opening 30.1, which is elastically deformed when the rotary latch 7 stops. The compressed at the stop of the catch 7 material of the damping element 30 is displaced in the direction of the opening 30.1, so that the opening 30.1 decreases.

Ferner umfasst der Mitnehmer 13 einen Betätigungsabschnitt 31, der an dem Basisabschnitt 19 angrenzt. Der Betätigungsabschnitt 31 weist einen Betätigungsnocken 32 auf, der mit einer Steuerkurve des Antriebselements 14 in Wirkverbindung steht. In diesem Ausführungsbeispiel ist eine Oberflächenebene des Betätigungsabschnitts 31 und eine Oberflächenebene des Basisabschnitts 19 in einem Winkel α von 45° zueinander angeordnet. Der Betätigungsnocken 32 betätigt ein als Mikroschalter ausgebildetes Schaltelement 33 mit einem ersten Kontakt 50, einem zweiten Kontakt 51 und einem dritten Kontakt 52 auf.

Der zweiten Schaltelementaufnahme 54 sind ebenfalls jeweils zwei aus der Ebene der Gehäuseunterschale 3 im Wesentlichen senkrecht hervorstehende Kontaktpinne 57 und 58 zugeordnet, wobei der Kontaktpin 57 einteilig mit der Leitung 33.1 und der Kontaktpin 58 mit der Leitung 33.2 ausgebildet ist. Wenn der Mikroschalter bis 10 Watt-Lampenlast abgesichert werden soll, dann wird wie im vorliegenden Ausführungsbeispiel der Mikroschalter in die Schaltelementaufnahme 54 montiert und der erste Kontakt 50 des Mikroschalters mit dem Kontaktpin 57 sowie der dritte Kontakt 52 des Mikroschalters mit dem Kontaktpin 58 elektrisch verbunden. Die erste Schaltelementaufnahme 53 bleibt dabei unbelegt. Generell ist immer nur eine Schaltelementaufnahme 53 oder 54 mit einem Mikroschalter besetzt. Falls der Mikroschalter zwischen 10 Watt-Lampenlast und 30 Watt-Lampenlast abgesichert werden soll, so wird der Mikroschalter in die Schaltelementaufnahme 53 montiert und der dritte Kontakt 52 des Mikroschalters mit dem Kontaktpin 55 sowie der zweite Kontakt 51 des Mikroschalters mit dem Kontaktpin 56 elektrisch verbunden.Furthermore, the driver 13 comprises an actuating portion 31 which adjoins the base portion 19. The actuating portion 31 has an actuating cam 32 which is in operative connection with a control cam of the drive element 14. In this embodiment, a surface plane of the operating portion 31 and a surface plane of the base portion 19 are arranged at an angle α of 45 ° to each other. The actuating cam 32 actuates a switching element 33 designed as a microswitch with a first contact 50, a second contact 51 and a third contact 52. The switching element 33 is connected to a first line 33.1 (plus microswitch) and a second line 33.2 (ground), which lead into the connector receptacle 6. In addition, a third line 33.3 (plus electric motor 15) associated with the electric motor 15, which also leads into the connector receptacle 6. In the lower housing shell a plurality of support rods 59 for holding the lines 33.1, 33.2 and 33.3 are arranged, which are integrally formed with the housing lower shell 3. The lines 33.1, 33.2 and 33.3 are plugged onto the support rods 59 and heat staked. Furthermore, the housing lower shell 3 has two switching element receptacles 53 and 54, which each have two round and one quadrangular recess, which serve for fastening the switching element. The first switching element receptacle 53 are each associated with two contact spiders 55 and 56 which project substantially perpendicularly from the plane of the housing lower shell 3, wherein the contact pin 55 is formed integrally with the line 33.2 and the contact pin 56 with the line 33.1. The second switching element receptacle 54 are also each assigned two contact spiders 57 and 58, which project substantially perpendicularly from the plane of the housing lower shell 3, wherein the contact pin 57 is formed integrally with the line 33.1 and the contact pin 58 with the line 33.2. If the microswitch is to be protected to 10 watt lamp load, then as in the present embodiment, the microswitch is mounted in the switching element receptacle 54 and the first contact 50 of the microswitch with the contact pin 57 and the third contact 52 of the microswitch electrically connected to the contact pin 58. The first switching element receptacle 53 remains unoccupied. In general, only one switching element receptacle 53 or 54 is always occupied by a microswitch. If the microswitch is to be protected between 10 watt lamp load and 30 watt lamp load, then the microswitch is mounted in the switching element receptacle 53 and the third contact 52 of the microswitch is electrically connected to the contact pin 55 and the second contact 51 of the microswitch is electrically connected to the contact pin 56 ,

Der in der Schaltelementaufnahme 54 angeordnete Mikroschalter wird im vorliegenden Ausführungsbeispiel durch eine Betätigungsschräge 60 des Mitnehmers 13 betätigt, und zwar wenn sich das Türschloss in der Vorraststellung bzw. in der Öffnungsstellung befindet. Durch die Betätigung des Mikroschalters wird in der Vorraststellung, beispielsweise ein am Armaturenbrett des Kraftfahrzeugs angeordnetes Anzeigeelement aktiviert, welches dem Benutzer anzeigt bzw. warnt, dass die Heckklappe oder Seitentür geöffnet ist. Dem Anzeigeelement ist mindestens eine Lampe zugeordnet, welche mit einer vorgegebenen Lampenlast betreibbar ist. In Abhängigkeit der geforderten Lampenlast zur Anzeige der Öffnungs- bzw. Schließstellung wird der Mikroschalter ausgewählt. Dadurch, dass zwei Schaltelementaufnahme 53, 54 zur Verfügung stehen, reichen zwei Leitungen 33.1 und 33.2 aus. Die Schaltelementaufnahmen 53, 54 sind einteilig mit der Gehäuseunterschale 3 ausgebildet und sind deshalb einfach und kostengünstiger herzustellen, als zusätzlich weitere Leiterbahnen in der Gehäuseunterschale 3 nachträglich zu montieren. Je nach Anforderung, ob 10 Watt-Lampenlast oder 10 bis 30 Watt-Lampenlast, muss ein Werker oder eine Maschine während der Montage lediglich nur den Mikroschalter in die entsprechende Schaltelementaufnahme 53 oder 54 stecken und die entsprechenden Kontaktpinne des Mikroschalters mit den entsprechenden Kontaktpinne der Leitungen 33.1 und 33.2 verbinden.The arranged in the switching element holder 54 microswitch is actuated in the present embodiment by an actuating slope 60 of the driver 13, and that when the door lock in the pre-locked position or in the open position. By actuation of the microswitch is activated in the pre-locking position, for example, arranged on the dashboard of the motor vehicle display element, which indicates to the user or warns that the tailgate or side door is open. The display element is associated with at least one lamp which is operable with a predetermined lamp load. Depending on the required lamp load to display the open or closed position of the microswitch is selected. Because two switching element receptacles 53, 54 are available, two lines 33.1 and 33.2 are sufficient. The switching element receptacles 53, 54 are formed integrally with the housing lower shell 3 and are therefore simple and inexpensive to manufacture, as additional additional strip conductors in the housing lower shell 3 to be retrofitted. Depending on the requirements, whether 10-watt lamp load or 10 to 30-watt lamp load, a worker or a machine during assembly only the microswitch in the appropriate switching element receptacle 53 or 54 stuck and the corresponding contact pin of the microswitch with the corresponding contact pin of the lines Connect 33.1 and 33.2.

The closing operation of the door lock assembly 1 is performed without the operation of the electric motor 15 to save power. The door lock assembly 1 is in Direction of the striker 16 moves, for example, by closing the tailgate or the side door or the front door of the motor vehicle, whereby the striker 16, the catch 7 contacts. The spring-loaded rotary latch 7 is rotated counterclockwise and biased in the course of the closing operation. In this case, the spring-loaded pawl 8 first reaches the pre-locking position, in which the latching section 8.1 contacts the pre-catch 9, as in FIG FIG. 2 shown. The pawl 8 takes along the driver 13 via the first wall 20, so that both components move simultaneously in the direction of the catch 7 at the same time in the direction of the clockwise direction. After the latching section 8.1 has left the area of the preliminary catch 9, the latching section 8.1 remains in a trough-shaped section 37 of the rotary latch 7 because of the spring element 24, in particular by the voltage applied to the shoulder 27 of the pawl 8 movable spring leg 25. In this case, the pawl 8 contacted within the recess 17, the inner surface of the first wall 20 and pushes the driver 13 in the direction of the trough-shaped portion 37th

Nachdem die Sperrklinke 8 den muldenförmigen Abschnitt 37 der Drehfalle 7 passiert hat, gelangt der Rastabschnitt 8.1 der Sperrklinke 8 zu dem Hauptrastabschnitt 36, welcher dafür sorgt, dass die Sperrklinke 8 relativ zum Mitnehmer 13 bewegt wird und der Mitnehmer 13 in seiner Position zunächst verbleibt. Dabei schwenkt die Sperrklinke 8 aus der Ausnehmung 17 des Mitnehmers 13 heraus und bewegt sich in Richtung des Uhrzeigersinns, wobei insbesondere der an der Schulter 27 angrenzende Abschnitt der Sperrklinke 8 sich aus der Ausnehmung 17 herausbewegt (siehe Figur 3). Die Sperrklinke 8 wird durch den an der Drehfalle 7 und an der Hauptrast 10 angrenzenden hervorstehenden Hauptrastabschnitt 36 bezüglich des Stellweges weiter in Richtung des Uhrzeigersinns ausgelenkt als der Mitnehmer 13. Der Hauptrastabschnitt 36 wirkt der Federkraft des Federelements 24 entgegen und drückt die Sperrklinke 8 daher aus der Ausnehmung des Mitnehmers 13 heraus, wobei das Federelement 24 vorgespannt wird. Der Mitnehmer 13 verbleibt durch die Kopplung mit dem Antriebselement 14 in seiner Position. Da der Mitnehmer 13 und die Sperrklinke 8 relativ zueinander beweglich sind und der Mitnehmer 13 zuvor nicht den gleichen Stellweg wie die Sperrklinke 8 durchlaufen hat, ist der Abstand zwischen Mitnehmer 13 und Drehfalle 7 im Wesentlichen identisch zu dem Abstand, welchen der Mitnehmer 13 bereits in der Vorraststellung aufwies.After the pawl 8 has passed the trough-shaped section 37 of the rotary latch 7, the latching section 8.1 of the pawl 8 arrives at the main catch section 36, which ensures that the pawl 8 is moved relative to the driver 13 and the driver 13 initially remains in its position. In this case, the pawl 8 pivots out of the recess 17 of the driver 13 and moves in the clockwise direction, wherein in particular the adjacent to the shoulder 27 portion of the pawl 8 moves out of the recess 17 (see FIG. 3 ). The pawl 8 is deflected by the adjacent to the catch 7 and the main catch 10 protruding Hauptast section 36 with respect to the travel further in the clockwise direction than the driver 13. The Haupttrastabschnitt 36 counteracts the spring force of the spring element 24 and therefore pushes the pawl 8 the recess of the driver 13 out, wherein the spring element 24 is biased. The driver 13 remains in its position by the coupling with the drive element 14. Since the driver 13 and the pawl 8 are movable relative to each other and the driver 13 has not previously gone through the same travel as the pawl 8, the distance between the driver 13 and 7 rotary latch is substantially identical to the distance which the driver 13 already had in the pre-locked position.

Nachdem der Rastabschnitt 8.1 den Hauptrastabschnitt 36 passiert hat, gelangt der Rastabschnitt 8.1 in die Hauptraststellung, dargestellt in Figur 4. Dabei nimmt die durch das Federelement 24 vorgespannte Sperrklinke 8 den Mitnehmer 13 über die erste Wand 20 mit, so dass beide Bauteile sich gegen die Richtung des Uhrzeigersinns in Richtung der Drehfalle 7 bewegen.After the latching section 8.1 has passed the main latching section 36, the latching section 8.1 reaches the main latching position, shown in FIG FIG. 4 , The biased by the spring member 24 pawl 8 takes the driver 13 on the first wall 20 so that both components move in the direction of the rotary latch 7 against the direction of clockwise.

Im Verlauf des Schließvorgangs wird aufgrund des im Wesentlichen unveränderten und geringen Abstands des Mitnehmers 13 zur Drehfalle 7 beim Anschlag des Vorsprungs 61 an den Begrenzungsabschnitt 38 das Anschlagsgeräusch minimiert, weil der Mitnehmer 13 wegen des geringen zurückgelegten Stellweges von der Position in Figur 3 zu Figur 4 eine geringere Beschleunigung erfährt, und dadurch weniger anfängt zu schwingen. Da der Mitnehmer 13 über den Dorn 23 mit der Sperrklinke 8 gekoppelt ist, wird dementsprechend auch die Sperrklinke 8 gedämpft. Zeitgleich schlägt auch der Mitnehmer 13 ebenfalls geräuschminimiert mit seinem Nockenabschnitt 29 am Dämpfungselement 30 an. Insgesamt wird dadurch die Geräuschentwicklung des Türschlosses in vorteilhafterweise verringert. Ebenfalls ist die Stärke des Aufpralls des Mitnehmers 13 mit seinem Vorsprung 61 an den Begrenzungsabschnitt 38 der Drehfalle 7 geringer, so dass der Mitnehmer anstatt aus Metall auch aus Kunststoff hergestellt werden kann. Zusätzlich wird noch die Lebensdauer des Mitnehmers 13 erhöht. Nach Beendigung des Schließvorgangs hat die Drehfalle 7 den Schließbügel 16 gefangen und die Türschlossbaugruppe 1 befindet sich der Schließstellung.In the course of the closing operation, the stop sound is minimized due to the substantially unchanged and small distance of the driver 13 to the rotary latch 7 when the projection 61 abuts against the limiting section 38, because the driver 13 is minimized because of the small trajectory traveled from the position in FIG FIG. 3 to FIG. 4 a lower acceleration experiences, and thus less begins to swing. Since the driver 13 is coupled via the mandrel 23 with the pawl 8, accordingly, the pawl 8 is attenuated. At the same time, the driver 13 also suggests a minimum noise with its cam portion 29 on the damping element 30. Overall, the noise of the door lock is thereby advantageously reduced. Also, the strength of the impact of the driver 13 with its projection 61 to the limiting portion 38 of the rotary latch 7 is lower, so that the driver can be made of plastic instead of metal. In addition, the life of the driver 13 is increased. After completion of the closing process, the catch 7 has caught the striker 16 and the door lock assembly 1 is in the closed position.

Im Folgenden wird der Öffnungsvorgang der Türschlossbaugruppe1 näher beschrieben. Die während des Schließvorgangs durch das Federelement vorgespannte federgelagerte Drehfalle 7 hat immer das Bestreben sich in Richtung des Uhrzeigersinns zu drehen. In der Schließstellung in Figur 4 wird die Drehfalle 7 an ihrer Hauptrast 10 von dem Rastabschnitt 8.1 der Sperrklinke 8 gehalten und der Nockenabschnitt 29 des Mitnehmers 13 kontaktiert das Dämpfungselement 30. Der Mikroschalter ist dabei in einer unbetätigten Stellung. Wenn ein Benutzer einen mit der Türschlossbaugruppe 1 in Wirkverbindung stehenden Hecktaster einer Heckklappe, oder alternativ einen Taster einer Seitentür betätigt, oder eine Taste auf einer dem Kraftfahrzeug zugeordneten Fernbedienung drückt, wird ein Steuergerät aktiviert, welches den Elektromotor 15 ansteuert, um diesen zu starten. Beim Start des Elektromotors 15 wird das Antriebselement 14 in Bewegung versetzt und treibt den Mitnehmer 13 an. Der Mitnehmer 13 wird zunächst um die durch den Dorn 23 definierte Schwenkachse in Richtung des Uhrzeigersinns geschwenkt und nimmt die Sperrklinke 8 mit Hilfe der Wand 20 mit, an welcher die Sperrklinke 8 anliegt. Der Mikroschalter wird durch die Betätigungsschräge 60 des Mitnehmers betätigt und das nicht näher dargestellte Anzeigeelement am Armaturenbrett zeigt an, dass das Türschloss sich nicht vollständig in der Schließstellung befindet. Insbesondere während der Fahrt wird der Benutzer des Kraftfahrzeugs mit Hilfe des Anzeigenelements darauf hingewiesen, dass die Heckklappe oder Seitentür nicht ordnungsgemäß geschlossen ist und kann ggf. mit dem Kraftfahrzeug halten, um die Heckklappe oder Seitentür zu schließen. Gleichzeitig verliert der Rastabschnitt 8.1 der Sperrklinke 8 den Kontakt zur Hauptrast 10 der Drehfalle 7. Die federgelagerte Drehfalle 7, welche zuvor durch die Sperrklinke 8 gehalten wurde, dreht sich schlagartig durch die Federspannung zurück in die in Figur 1 gezeigte Öffnungsstellung. Danach schwenkt der Mitnehmer 13 und die in der Ausnehmung 17 angeordnete Sperrklinke 8 gegen die Richtung des Uhrzeigersinns, wobei die Sperrklinke 8 an die Drehfalle 7 anschlägt und der Vorsprung 61 des Mitnehmers 13 an den Begrenzungsabschnitt 38 anschlägt. Während des gesamten Öffnungsvorgangs führen der Mitnehmer 13 und die Sperrklinke 8 keine Relativbewegung zueinander aus, d.h., dass die Schulter 27 in ihrer Position innerhalb des Mitnehmers 13 verbleibt, ohne aus dem Mitnehmer auszuschwenken.Hereinafter, the opening operation of the door lock assembly 1 will be described in more detail. The biased by the spring element spring-loaded rotary latch 7 during the closing process always has the tendency to rotate in the clockwise direction. In the closed position in FIG. 4 the catch 7 is held at its main catch 10 of the locking portion 8.1 of the pawl 8 and the cam portion 29 of the driver 13 contacts the damping element 30. The micro-switch is in an unactuated position. When a user operates a tailgate door latch button operatively connected to the door lock assembly 1, or alternatively a side door button, or a button presses a remote control associated with the motor vehicle, a control unit is activated, which controls the electric motor 15 to start this. When starting the electric motor 15, the drive element 14 is set in motion and drives the driver 13 at. The driver 13 is first pivoted in the clockwise direction about the pivot axis defined by the mandrel 23 and takes the pawl 8 by means of the wall 20, against which the pawl 8 rests. The microswitch is actuated by the operating slope 60 of the driver and the display element not shown on the dashboard indicates that the door lock is not completely in the closed position. In particular, while driving the user of the motor vehicle with the help of the display element is pointed out that the tailgate or side door is not properly closed and can possibly hold with the motor vehicle to close the tailgate or side door. At the same time the locking portion 8.1 of the pawl 8 loses contact with the main catch 10 of the rotary latch 7. The spring-loaded rotary latch 7, which was previously held by the pawl 8, abruptly rotates back through the spring tension in the in FIG. 1 shown opening position. Thereafter, the driver 13 and arranged in the recess 17 pawl 8 pivots counterclockwise, the pawl 8 abuts against the catch 7 and the projection 61 of the driver 13 abuts against the limiting portion 38. During the entire opening process, the driver 13 and the pawl 8 do not perform any relative movement, ie, the shoulder 27 remains in its position within the driver 13, without swinging out of the driver.
