Definitions
- the invention is directed to a motor vehicle door lock with a closed position in the closed position closing element and in the direction of the closing element biased open position rotary latch, a pawl which engages in an engaged position with the rotary latch in such a manner that the rotary latch on a movement in the direction of the open position and a drive member to which a coupling portion of the pawl is movably coupled and which moves the pawl between the engaged position and a release position in which the pawl is disengaged from the rotary latch so that the rotary latch can move in the open position
- the drive element is formed as an eccentric disc having an eccentric pin arranged outside its center, which is drive shaft connected to a drive unit, and wherein the drive element, the pawl during the initial loading movement from the engagement position in the direction of the release position moves such that during this movement with the pawl still engaged rotary catch moves in the direction of the open position.
- a motor vehicle door lock of the aforementioned type is for example from the EP 0 397 866 A1 known.
- a motor vehicle door lock from the DE 10 2007 024 672 A1 known.
- This known motor vehicle door lock is used for example in a tailgate of a motor vehicle and comprises a connected to a trunk lid, usually designed as a rotary latch element and a connected to a body of the vehicle lock counterpart, which may be in the form of a striker or latch bolt.
- a control device Through which the Tailgate by means of a drive element, which is preferably operated by electric motor, can be opened.
- a pivotally mounted pawl from an engagement position in which the pawl is in engagement with the rotary latch, deflected in the direction of a release position of the drive element until it has reached the release position and is no longer engaged with the catch, whereby a rotational movement the catch is released from the closed position in the direction of an open position.
- the invention has for its object to provide a solution that provides a motor vehicle door lock in a structurally simple manner and cost, in which the opening noise is reduced to a minimum, or at least in which the opening process no clearly audible and the comfort negatively impairing noise generated.
- the object is achieved in that the movement of the eccentric is a rotary movement, wherein the rotational direction of the rotational movement of the eccentric around the eccentric pin around the movement of the pawl from the engaged position to the release position and from the release position back in the engaged position is the same.
- the invention provides a motor vehicle door closure which contributes to increasing the comfort and quality of the closure and its operation.
- the motor vehicle door lock according to the invention is characterized by a functional design and has a simple and inexpensive construction.
- the bias of the tailgate degrades because the defined movement of the pawl causes a relative movement between the motor vehicle door lock and the closing element and thus relieving the tailgate, wherein the rotary latch to a predetermined rotational movement in the open position is turned.
- the invention provides that the bias between the tailgate or motor vehicle door lock and closing element is reduced before the pawl and the catch are disengaged.
- the drive element is designed as an eccentric, because this is dispensed with in contrast to other known motor vehicle door locks on a lever mechanism and / or on toggle that take a lot more installation space and where additionally due to the limited installation and movement space, the rotational movement of the drive element is limited to a minimum.
- the coupling portion of the pawl has a bearing opening which rotatably receives the eccentric disc, so that the eccentric disc can rotate relative to the pawl in the bearing opening. Because the eccentric disc is driven via the eccentric eccentric pin, a circular movement of the bearing opening of the detent pawl is ultimately effected by means of the eccentric disc. This serves to reduce the preload, with which the tailgate is biased in the closed position, gradually and not abruptly.

- the movement of the pawl executed during the opening process of the motor vehicle door lock is thus divided into two or consists of a sequence of movements in which the pawl is moved in at least two different spatial directions. To initially take the pressure from the tailgate in the closed position or to relieve the preloaded tailgate, there is a substantially tangential movement of the pawl with respect to the catch.
- a structurally particularly simple way of defined guidance of the pawl in the release position is in a further embodiment of the motor vehicle door lock in that a in the engaged position with the rotary catch engaging latching portion of the pawl by means of a guide member and / or attached to the pawl control pin is.

Description
Die Erfindung richtet sich auf einen Kraftfahrzeugtürverschluss mit einer in Schließstellung ein Schließelement umgreifenden und in Richtung einer das Schließelement freigebenden Offenstellung vorgespannten Drehfalle, einer Sperrklinke, die in einer Eingriffsstellung mit der Drehfalle derart in Eingriff steht, dass die Drehfalle an einer Bewegung in Richtung der Offenstellung gehindert ist, und einem Antriebselement, mit dem ein Kopplungsabschnitt der Sperrklinke bewegungsgekoppelt ist und das die Sperrklinke zwischen der Eingriffsstellung und einer Freigabestellung bewegt, in welcher die Sperrklinke mit der Drehfalle außer Eingriff steht, so dass sich die Drehfalle in Richtung der Offenstellung bewegen kann, wobei das Antriebselement als Exzenterscheibe ausgebildet ist, die einen außerhalb ihres Mittelpunktes angeordneten Exzenterbolzen aufweist, der mit einer Antriebseinheit antriebswellenverbunden ist, und wobei das Antriebselement die Sperrklinke während der anfänglichen Bewegung aus der Eingriffsstellung in Richtung der Freigabestellung derart bewegt, dass sich die bei dieser Bewegung mit der Sperrklinke nach wie vor in Eingriff stehende Drehfalle in Richtung der Offenstellung bewegt.The invention is directed to a motor vehicle door lock with a closed position in the closed position closing element and in the direction of the closing element biased open position rotary latch, a pawl which engages in an engaged position with the rotary latch in such a manner that the rotary latch on a movement in the direction of the open position and a drive member to which a coupling portion of the pawl is movably coupled and which moves the pawl between the engaged position and a release position in which the pawl is disengaged from the rotary latch so that the rotary latch can move in the open position, wherein the drive element is formed as an eccentric disc having an eccentric pin arranged outside its center, which is drive shaft connected to a drive unit, and wherein the drive element, the pawl during the initial loading movement from the engagement position in the direction of the release position moves such that during this movement with the pawl still engaged rotary catch moves in the direction of the open position.
Ein Kraftfahrzeugtürverschluss der eingangs genannten Art ist beispielsweise aus der
Ferner ist ein Kraftfahrzeugtürverschluss aus der
In Schließstellung der Heckklappe ist diese beispielsweise gegen eine Dichtung vorgespannt. Unter Vorspannung ist hierbei zu verstehen, dass der von einer Klappendichtung verursachte Dichtungsgegendruck dem Schließen der Kraftfahrzeugklappe entgegenwirkt. Dadurch herrscht aufgrund der von der Heckklappe komprimierten Dichtung ein hoher Druck in Öffnungsrichtung der Heckklappe. Wenn die Sperrklinke mit der Drehfalle außer Eingriff gelangt, baut sich der durch die Dichtung aufgebaute Druck in Form eines sogenannten Entlastungsschlags schnell ab und die Heckklappe bewegt sich schlag- und ruckartig in Richtung der Öffnungsrichtung, was sich in einem akustisch hörbaren Öffnungsgeräusch negativ bemerkbar macht und zu Einbußen im Komfort führt.In the closed position of the tailgate this is biased for example against a seal. Under bias is to be understood here that the sealing gasket pressure caused by a flap seal counteracts the closing of the motor vehicle door. As a result, there is a high pressure in the opening direction of the tailgate due to the compressed from the tailgate seal. When the pawl is disengaged from the catch, the pressure built up by the seal builds up rapidly in the form of a so-called unloading stroke and the tailgate moves abruptly and jerkily in the direction of the opening direction, which is negatively noticeable in an acoustically audible opening noise and leads to losses in comfort.
Der Erfindung liegt die Aufgabe zugrunde eine Lösung zu schaffen, die auf konstruktiv einfache Weise und kostengünstig einen Kraftfahrzeugtürverschluss bereitstellt, bei dem das Öffnungsgeräusch auf ein Minimum reduziert ist, zumindest aber bei dem der Öffnungsvorgang kein deutlich hörbares und den Komfort negativ beeinträchtigendes Geräusch erzeugt.The invention has for its object to provide a solution that provides a motor vehicle door lock in a structurally simple manner and cost, in which the opening noise is reduced to a minimum, or at least in which the opening process no clearly audible and the comfort negatively impairing noise generated.
Bei einem Kraftfahrzeugtürverschluss der eingangs bezeichneten Art wird die Aufgabe erfindungsgemäß dadurch gelöst, dass die Bewegung der Exzenterscheibe eine Drehbewegung ist, wobei die Drehrichtung der Drehbewegung der Exzenterscheibe um den Exzenterbolzen herum zur Bewegung der Sperrklinke aus der Eingriffsstellung in die Freigabestellung und aus der Freigabestellung zurück in die Eingriffsstellung die gleiche ist. Durch das "nach wie vor in Eingriff stehen" von Sperrklinke und Drehfalle bei der anfänglichen Bewegung aus der Eingriffsstellung wird die Geschwindigkeit der Bewegung der Drehfalle zur Freigabe des Schließelements verzögert, denn die Bewegung der Drehfalle ist an die kontrollierte Bewegung der Sperrklinke angepasst, so dass ein plötzliches und geräuschbehaftetes Aufschlagen der Drehfalle und den Kraftfahrzeugtürverschlusses verhindert wird und die Vorspannung durch die Dichtung zunächst durch die anfänglich kontrollierte und verzögerte Bewegung der Drehfalle abgebaut wird.In a motor vehicle door lock of the type described, the object is achieved in that the movement of the eccentric is a rotary movement, wherein the rotational direction of the rotational movement of the eccentric around the eccentric pin around the movement of the pawl from the engaged position to the release position and from the release position back in the engaged position is the same. By the "still engaged" by pawl and catch in the initial movement from the engaged position, the speed of movement of the rotary latch is released to release the closing element, because the movement of the rotary latch is adapted to the controlled movement of the pawl, so that a sudden and noisy impact of the catch and the motor vehicle door lock is prevented and the bias through the seal is first relieved by the initially controlled and delayed movement of the catch.
Vorteilhafte und zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous and expedient refinements and developments of the invention will become apparent from the dependent claims.
Durch die Erfindung wird ein Kraftfahrzeugtürverschluss zur Verfügung gestellt, der zur Erhöhung des Komforts und der Qualität des Verschlusses und dessen Funktionsweise beiträgt. Der erfindungsgemäße Kraftfahrzeugtürverschluss zeichnet sich durch eine funktionsgerechte Konstruktion aus und weist einen einfachen und kostengünstigen Aufbau auf. Durch die Auslösemechanik des Kraftfahrzeugtürverschlusses gemäß der vorliegenden Erfindung stehen die Sperrklinke und die Drehfalle zumindest während eines anfänglichen Bewegungsvorgangs der Sperrklinke in Richtung der Freigabestellung nach wie vor in Eingriff. Zwar ermöglicht diese Bewegung der Sperrklinke nicht das Öffnen der Heckklappe. Jedoch wird durch diese (erste bzw. anfängliche) Bewegung beim Öffnungsvorgang die Vorspannung der Heckklappe abgebaut, da die definierte Bewegung der Sperrklinke eine Relativbewegung zwischen dem Kraftfahrzeugtürverschluss und dem Schließelement und somit eine Entlastung der Heckklappe bewirkt, wobei die Drehfalle um eine vorbestimmte Drehbewegung in Offenstellung gedreht wird. Dadurch wird der Heckklappe letztlich ermöglicht, sich um einen definierten Hub relativ zum Schließelement zu bewegen, wodurch die Vorspannung und der Druck genommen ist, welcher zuvor bei den aus dem Stand der Technik bekannten Kraftfahrzeugtürverschlüssen für das akustisch wahrnehmbare und störende Öffnungsgeräusch verantwortlich war. Demnach sieht die Erfindung vor, dass die Vorspannung zwischen Heckklappe bzw. Kraftfahrzeugtürverschluss und Schließelement reduziert wird, bevor die Sperrklinke und die Drehfalle außer Eingriff gebracht werden. Dabei ist von besonderem Vorteil, dass das Antriebselement als Exzenterscheibe ausgebildet ist, denn dadurch wird im Gegensatz zu anderen bekannten Kraftfahrzeugtürverschlüssen auf ein Hebelgetriebe und/oder auf Gelenkhebel verzichtet, die sehr viel mehr Einbauraum in Anspruch nehmen und bei denen zusätzlich aufgrund des begrenzten Einbau- und Bewegungsraumes die Drehbewegung des Antriebselements auf ein Mindestmaß beschränkt ist.The invention provides a motor vehicle door closure which contributes to increasing the comfort and quality of the closure and its operation. The motor vehicle door lock according to the invention is characterized by a functional design and has a simple and inexpensive construction. By the trigger mechanism of the motor vehicle door lock according to the present invention, the pawl and the rotary latch are still at least during an initial movement operation of the pawl in the direction of the release position still engaged. Although this movement of the pawl does not allow the opening of the tailgate. However, by this (first or initial) movement during the opening process, the bias of the tailgate degrades because the defined movement of the pawl causes a relative movement between the motor vehicle door lock and the closing element and thus relieving the tailgate, wherein the rotary latch to a predetermined rotational movement in the open position is turned. This ultimately allows the tailgate to move a defined stroke relative to the closure member, thereby relieving the preload and pressure previously responsible for the acoustically perceptible and disturbing opening noise in the automotive door closures known in the art. Accordingly, the invention provides that the bias between the tailgate or motor vehicle door lock and closing element is reduced before the pawl and the catch are disengaged. It is of particular advantage that the drive element is designed as an eccentric, because this is dispensed with in contrast to other known motor vehicle door locks on a lever mechanism and / or on toggle that take a lot more installation space and where additionally due to the limited installation and movement space, the rotational movement of the drive element is limited to a minimum.
Die Erfindung sieht in vorteilhafter Ausgestaltung vor, dass der Kopplungsabschnitt der Sperrklinke eine Lageröffnung aufweist, welche die Exzenterscheibe drehbar aufnimmt, so dass sich die Exzenterscheibe relativ zu der Sperrklinke in der Lageröffnung drehen kann. Dadurch, dass die Exzenterscheibe über den außermittig angeordneten Exzenterbolzen angetrieben ist, wird letztlich mit Hilfe der Exzenterscheibe eine kreisförmige Bewegung der Lageröffnung der Sperrklinke bewirkt. Dies dient dazu, dass die Vorspannung, mit welcher die Heckklappe in Schließstellung vorgespannt ist, allmählich und nicht schlagartig abgebaut wird. Diese kreisförmige Bewegung kann eine kreisabschnittsförmige Bewegung sein, wie zum Beispiel eine viertelkreisförmige oder auch halbkreisförmige Bewegung. Die Sperrklinke wird im Bereich ihrer Lageröffnung mittels der Exzenterscheibe folglich entlang einer Kreisbahn bewegt, wobei die Lageröffnung gleichzeitig den Drehpunkt der Sperrklinke definiert. Die Sperrklinke ist damit frei um die Exzenterscheibe als Drehpunkt drehbar, wobei der Drehpunkt infolge des Exzenterbolzens relativ zu einer ortsfesten Drehachse der Drehfalle bewegbar und verschiebbar ist.The invention provides in an advantageous embodiment, that the coupling portion of the pawl has a bearing opening which rotatably receives the eccentric disc, so that the eccentric disc can rotate relative to the pawl in the bearing opening. Because the eccentric disc is driven via the eccentric eccentric pin, a circular movement of the bearing opening of the detent pawl is ultimately effected by means of the eccentric disc. This serves to reduce the preload, with which the tailgate is biased in the closed position, gradually and not abruptly. This circular motion may be a circular motion, such as a quarter circle or semi-circular motion. The pawl is thus moved in the region of its bearing opening by means of the eccentric disc along a circular path, wherein the bearing opening simultaneously defines the pivot point of the pawl. The pawl is thus freely rotatable about the eccentric disc as a fulcrum, wherein the fulcrum is movable and displaceable due to the eccentric pin relative to a stationary axis of rotation of the rotary latch.
Für einen minimalen Einbauraum bei gleichzeitig großer Funktionalität des Kraftfahrzeugtürverschlusses ist es bei der Erfindung von Vorteil, wenn die Bewegung der Exzenterscheibe eine Drehbewegung ist, wobei die Drehrichtung der Drehbewegung der Exzenterscheibe um den Exzenterbolzen herum zur Bewegung der Sperrklinke aus der Eingriffsstellung in die Freigabestellung und aus der Freigabestellung zurück in die Eingriffsstellung die gleiche ist. Um somit die Sperrklinke wieder in eine gewünschte Stellung zurückzubewegen, muss der Antriebsmotor keinen Rücklauf aufweisen, sondern er muss lediglich die gleiche Antriebskraft für eine in die gleiche Richtung weisende bewegen zur Verfügung stellen. Mit Bezug auf den Kraftfahrzeugtürverschluss muss der Antriebsmotor damit einfach eine Drehbewegung in eine Richtung realisieren, die sowohl dem Öffnen als auch dem Schließen dient. Auf diese Weise muss kein reversierender Antriebsmotor eingesetzt werden, sondern es reicht ein dazu kostengünstigerer Antriebsmotor, der eine Drehbewegung in die eine Richtung bewirkt.For a minimal installation space with great functionality of the motor vehicle door lock, it is advantageous in the invention if the movement of the eccentric disc is a rotary movement, wherein the rotational direction of the rotational movement of the eccentric around the eccentric pin around the movement of the pawl from the engaged position to the release position and off the release position is back to the engaged position the same. Thus, the pawl back into a desired To move back position, the drive motor must have no return, but he must provide only the same driving force for pointing in the same direction move available. With respect to the motor vehicle door lock of the Drive motor so that simply realize a rotational movement in one direction, which serves both the opening and the closing. In this way, no reversing drive motor must be used, but it is sufficient to a more cost-effective drive motor, which causes a rotational movement in one direction.
In Ausgestaltung des Kraftfahrzeugtürverschlusses sieht die Erfindung vor, dass die Drehbewegung des als Exzenterscheibe ausgebildeten Antriebselements während der Bewegung der Sperrklinke aus der Eingriffsstellung in Richtung der Freigabestellung eine in Bezug auf die Drehfalle im Wesentlichen tangentiale Bewegung eines mit der Drehfalle zusammenwirkenden Rastabschnitts der Sperrklinke und dann, um die Sperrklinke und die Drehfalle außer Eingriff zu bringen, eine im Wesentlichen radial von der Drehfalle wegweisende Bewegung des Rastabschnitts der Sperrklinke bewirkt. Diese Bewegung bezieht sich allein auf den Rastabschnitt der Sperrklinke, welcher in der Eingriffsstellung mit der Drehfalle in Eingriff steht. Mit anderen Worten wird das Antriebselement zum Öffnen des Kraftfahrzeugtürverschlusses derart gedreht, dass die Sperrklinke oder zumindest ein Abschnitt der Sperrklinke, d.h. der Rastabschnitt, zunächst während der Bewegung aus der Eingriffsstellung in Richtung der Freigabestellung im Wesentlichen tangential in Bezug auf die Drehfalle bewegt wird und dann, um die Sperrklinke und die Drehfalle außer Eingriff zu bringen, von der Drehfalle im Wesentlichen radial weg bewegt wird. Die beim Öffnungsvorgang des Kraftfahrzeugtürverschlusses ausgeführte Bewegung der Sperrklinke ist somit zweigeteilt bzw. besteht aus einer Bewegungsabfolge, bei welcher die Sperrklinke in wenigstens zwei verschiedene Raumrichtungen bewegt wird. Um in Schließposition zunächst den Druck von der Heckklappe zu nehmen bzw. die vorgespannte Heckklappe zu entlasten, erfolgt eine im Wesentlichen tangentiale Bewegung der Sperrklinke in Bezug auf die Drehfalle. Bei dieser Bewegung steht die Sperrklinke nach wie vor mit der Drehfalle in Eingriff, wobei jedoch in Abhängigkeit der tangentialen Distanz, um die die Sperrklinke bewegt wird, der Drehfalle eine Drehung in Offenstellung ermöglicht wird, wodurch sich der Druck der Heckklappe abbaut. Erst nach dem Druckabbau bzw. der Reduzierung der Vorspannung erfolgt dann mit Hilfe einer radialen Seitwärtsbewegung der Sperrklinke das außer Eingriff bringen mit der Drehfalle, wodurch diese dann zur Öffnung der Heckklappe das Schließelement freigibt. Die sich aus zwei Bewegungen in unterschiedlichen Raumrichtungen zusammensetzende Öffnungsbewegung der Sperrklinke ermöglicht somit den Abbau der auf die Heckklappe in Schließstellung wirkenden Vorspannung, indem die Sperrklinke eine kontrollierte Bewegung der Heckklappe in Öffnungsrichtung für einen gewissen Hub bewirkt.In an embodiment of the motor vehicle door lock, the invention provides that the rotational movement of the drive element formed as an eccentric disc during movement of the pawl from the engaged position in the direction of the release position with respect to the rotary latch substantially tangential movement of a cooperating with the rotary latch portion of the pawl and then to disengage the pawl and the catch causes a substantially radially away from the catch movement of the locking portion of the pawl. This movement relates solely to the latching portion of the pawl, which engages in the engaged position with the rotary latch. In other words, the drive element for opening the motor vehicle door lock is rotated such that the pawl or at least a portion of the pawl, ie the latching portion, initially during movement from the engaged position in the direction of the release position is moved substantially tangentially with respect to the rotary latch and then to disengage the pawl and the catch, is moved substantially radially away from the catch. The movement of the pawl executed during the opening process of the motor vehicle door lock is thus divided into two or consists of a sequence of movements in which the pawl is moved in at least two different spatial directions. To initially take the pressure from the tailgate in the closed position or to relieve the preloaded tailgate, there is a substantially tangential movement of the pawl with respect to the catch. In this movement, the pawl is still engaged with the rotary latch, however, depending on the tangential distance by which the pawl is moved, the catch a rotation in Open position is enabled, thereby reducing the pressure of the tailgate. Only after the pressure reduction or the reduction of the bias is then carried out with the aid of a radial sideways movement of the pawl disengage the catch, which then releases the closing element for opening the tailgate. The resulting from two movements in different directions in space opening movement of the pawl thus allows the degradation of acting on the tailgate in the closed position bias by the pawl causes a controlled movement of the tailgate in the opening direction for a certain stroke.
Eine Möglichkeit, die vorstehend beschriebene Bewegungsabfolge des Rastabschnitts der Sperrklinke zu realisieren, besteht in Ausgestaltung der Erfindung darin, dass die Bewegung des Kopplungsabschnitts der Sperrklinke aus der Eingriffsstellung in die Freigabestellung eine im Wesentlichen halbkreisförmige Bewegung ist. Eine Bewegung des Kopplungsabschnitts, der an einem der beiden Längsenden der Sperrklinke ausgebildet ist, ermöglicht eine Bewegung des Rastabschnitts, der an dem anderen Längsende der Sperrklinke ausgeformt ist.One way to realize the above-described sequence of movements of the locking portion of the pawl, is in an embodiment of the invention is that the movement of the coupling portion of the pawl from the engaged position to the release position is a substantially semi-circular motion. A movement of the coupling portion, which is formed at one of the two longitudinal ends of the pawl, allows movement of the latching portion, which is formed at the other longitudinal end of the pawl.
Eine konstruktiv besonders einfache Möglichkeit zur definierten Führung der Sperrklinke in die Freigabestellung besteht in weiterer Ausgestaltung des erfindungsgemäßen Kraftfahrzeugtürverschlusses darin, dass ein in der Eingriffsstellung mit der Drehfalle in Eingriff stehender Rastabschnitt der Sperrklinke mit Hilfe eines Führungselements und/oder eines an der Sperrklinke angebrachten Steuerzapfens bewegungsgeführt ist. Bei dieser geführten Bewegung wird beim Öffnungsvorgang die Sperrklinke von der Drehfalle radial weg bewegt, wobei es von besonderem Vorteil ist, wenn lediglich der mit der Drehfalle in Eingriff stehende Abschnitt der Sperrklinke und nicht die gesamte Sperrklinke von der Drehfalle weg bewegt wird.A structurally particularly simple way of defined guidance of the pawl in the release position is in a further embodiment of the motor vehicle door lock in that a in the engaged position with the rotary catch engaging latching portion of the pawl by means of a guide member and / or attached to the pawl control pin is. In this guided movement, the pawl is moved radially away from the rotary latch during the opening process, it being particularly advantageous if only the portion of the pawl engaged with the catch and not the entire pawl is moved away from the rotary latch.
In Ausgestaltung des Kraftfahrzeugtürverschlusses ist ferner vorgesehen, dass das Führungselement, welches an einem Gehäuseelement des Kraftfahrzeugtürverschlusses schwenkbar angeordnet ist, eine Führungsausnehmung aufweist, welche eine Bewegung des mit der Drehfalle in Eingriff bringbaren Rastabschnitts der Sperrklinke hin zu der Drehfalle oder weg von der Drehfalle führt. Alternativ hierzu könnte das Führungselement auch an der Drehfalle selbst ausgebildet sein und dafür sorgen, dass der Rastabschnitt der Sperrklinke mit der Drehfalle außer Eingriff gebracht wird.In an embodiment of the motor vehicle door lock, it is further provided that the guide element, which is pivotable on a housing element of the motor vehicle door lock is arranged, having a guide recess, which guides a movement of the engageable with the catch catch portion of the pawl to the catch or away from the catch. Alternatively, the guide element could also be formed on the catch itself and ensure that the latching portion of the pawl is disengaged from the catch.
Schließlich ist in Ausgestaltung des erfindungsgemäßen Kraftfahrzeugtürverschlusses vorgesehen, dass die Antriebseinheit einen Antriebsmotor, eine mit dem Antriebsmotor gekoppelte Antriebswelle mit einer Antriebsschnecke und ein mit der Antriebsschnecke in Eingriff stehendes Antriebszahnrad umfasst, welches mit dem Antriebselement bewegungsgekoppelt ist. Auch auf diese Weise lässt sich ein kompakter und wenig Bauraum beanspruchender Kraftfahrzeugtürverschluss erzielen.Finally, in an embodiment of the motor vehicle door lock according to the invention, it is provided that the drive unit comprises a drive motor, a drive shaft coupled to the drive motor with a drive worm and a drive gear meshing with the drive worm, which is motion-coupled to the drive element. In this way, a compact and little space consuming claim vehicle door lock can be achieved.

Zusammenfassend wurde ein Kraftfahrzeugtürverschluss 1 vorgestellt, welcher sich dadurch auszeichnet, dass die Geräuschentwicklung beim Öffnungsvorgang auf ein Minimum reduziert ist und insbesondere das Geräusch beim Entlastungsschlag minimiert ist. Dies wird dadurch erreicht, dass beim Öffnungsvorgang die Sperrklinke 6 und die Drehfalle 3 derart zueinander bewegt werden, dass sich die Heckklappe und damit der Kraftfahrzeugtürverschluss 1 relativ zu dem Schließelement 2 entfernen kann, wodurch der auf die Heckklappe lastende Druck bzw. die Vorspannung der Heckklappe zunächst reduziert wird, bevor die Sperrklinke 6 und die Drehfalle 3 endgültig außer Eingriff gelangen, um das Schließelement 2 freizugeben. Insbesondere wird dies dadurch erreicht, indem beim Öffnungsvorgang der Kopplungsabschnitt 9, der eine Schwenkachse für die Sperrklinke 6 definiert, relativ zur Drehachse 4 der Drehfalle 3 bewegt wird, wodurch die zunächst tangentiale Bewegung zur Drehfalle 3 und dann die radial von der Drehfalle 3 wegweisende Bewegung des Rastabschnitts 7 der Sperrklinke 6 umgesetzt wird. Die vorliegende Erfindung offenbart somit ein Heckschloss bzw. einen Kraftfahrzeugtürverschluss 1 für ein Kraftfahrzeug, mit der in Schließstellung das Schließelement 2 umgreifenden und in Richtung der das Schließelement 2 freigebenden Offenstellung vorgespannten Drehfalle 3 und der Sperrklinke 6, die zwischen der Freigabestellung und der Eingriffsstellung bewegbar ist, wobei die Sperrklinke 6 in der Freigabestellung mit der Drehfalle 3 außer Eingriff steht und in der Eingriffsstellung mit der Drehfalle 3 derart in Eingriff steht, das die Drehfalle 3 an einer Bewegung in Richtung der Offenstellung gehindert ist. Bei dem Kraftfahrzeugtürverschluss sind Verzögerungsmittel vorgesehen, die mit der Drehfalle 3 gekoppelt sind, um eine Geschwindigkeit einer Bewegung der Drehfalle 3 zur Freigabe des Schließelementes 2 zu verzögern. Dabei ist die Drehfalle 3 über die Sperrklinke 6 mit den Verzögerungsmitteln derart gekoppelt, dass die Geschwindigkeit der Bewegung der Drehfalle 3 zur Freigabe der Drehfalle 3 kontrolliert erfolgt. Dabei können die Verzögerungsmittel gleichzeitig eine Betätigung der Sperrklinke 6 bewirken. Bei dem dargestellten Ausführungsbeispiel ist das Antriebselement 10 das Verzögerungsmittel, welches für die Bewegung der Sperrklinke 6 und insbesondere die erwünschten Bewegungen des Kopplungsabschnitts 9 und des Rastabschnitts 7 ursächlich ist.In summary, a motor vehicle door lock 1 was presented, which is characterized in that the noise during opening is reduced to a minimum and in particular the noise is minimized in the discharge stroke. This is achieved in that the
