Description

Die Erfindung betrifft ein Kraftfahrzeugschloß mit einer Schloßfalle und einer Sperrklinkenanordnung gemäß Anspruch 1. Vorliegend sind unter dem Begriff Kraftfahrzeugschloß alle Arten von Tür-, Hauben- oder Klappenschlössern zusammengefaßt.The invention relates to a motor vehicle lock with a lock latch and a pawl arrangement according to claim 1. In the present case, all types of door, hood or flap locks are summarized under the term motor vehicle lock.

Heutige Kraftfahrzeugschlösser sind in der Regel mit einer Schloßfalle und mit einer Sperrklinke ausgestattet, um eine kraftschlüssige Verbindung mit einem an der Kraftfahrzeugkarosserie angeordneten Schließkloben o. dgl. zu realisieren (EP 0 589 158 A1). Die Schloßfalle ist dabei um eine Schwenkachse schwenkbar und jedenfalls in eine Hauptschließstellung bringbar. Die Sperrklinke ist hier hakenförmig ausgebildet und hält die Schloßfalle in der Hauptschließstellung, indem sie in eine entsprechende Ausformung ― Hauptrast ― an der Schloßfalle eingreift. Dieses Grundkonzept findet auch bei Kraftfahrzeugschlössern mit einem motorischen Öffnungsantrieb Anwendung, wie ebenfalls in der EP 0 589 158 A1 gezeigt ist.Today's motor vehicle locks are generally equipped with a lock latch and with a pawl in order to realize a non-positive connection with a locking block or the like arranged on the motor vehicle body (EP 0 589 158 A1). The lock latch can be pivoted about a pivot axis and can in any case be brought into a main closed position. The pawl is hook-shaped here and holds the lock latch in the main closed position by engaging in a corresponding shape - main catch - on the lock latch. This basic concept also applies to motor vehicle locks with a motorized opening drive, as is also shown in EP 0 589 158 A1.

Grundsätzlich stellt sich bei dem oben beschriebenen Kraftfahrzeugschloß das Problem, daß je nach Ausgestaltung von Schloßfalle und Sperrklinke das Ausheben der Sperrklinke und damit das Freigeben der Schloßfalle mit einer bestimmten Mindestkraft und einer bestimmten Mindestarbeit verbunden ist, die im wesentlichen durch die Reibkraft zwischen der Schloßfalle und der Sperrklinke während des Aushebens der Sperrklinke bestimmt wird. Neben dem Reibkoeffizienten ist für die Reibarbeit die von der Schloßfalle auf die Sperrklinke wirkende Rückstellkraft sowie der zum Ausheben der Sperrklinke erforderliche Verstellweg maßgebend.Basically, the problem with the motor vehicle lock described above arises that, depending on the design of the lock latch and pawl, the lifting of the pawl and thus the release of the lock latch is associated with a certain minimum force and a certain minimum work, which is essentially due to the frictional force between the lock latch and the pawl is determined while the pawl is being lifted. In addition to the coefficient of friction, the restoring force exerted by the lock latch on the pawl and the adjustment path required to lift the pawl are decisive for the friction work.

Unter Beibehaltung des beschriebenen Grundkonzepts ist eine Reduzierung der Reibkraft bzw. der Reibarbeit nur beschränkt möglich, ohne die Betriebssicherheit des Kraftfahrzeugschlosses zu gefährden. Dies führt dazu, daß es bei einem mechanisch betätigbaren Kraftfahrzeugschloß ggf. zu Komforteinbußen wegen hoher Betätigungskräfte kommt. Wenn das Kraftfahrzeugschloß mit einem motorischen Öffnungsantrieb ausgestattet ist, dann ist dieser Öffnungsantrieb entsprechend für hohe Kräfte bzw. Leistungen auszulegen. Dies führt zu hohen Platzanforderungen sowie zu hohen Kosten.
Einen Ansatz zur Reduzierung der zum Ausheben der Sperrklinke erforderlichen Kraft zeigt ein bekanntes Kraftfahrzeugschloß (DE 102 36 282 A1). Dieses zeigt eine Sperrklinkenanordnung bestehend aus zwei Sperrklinken. Die erste Sperrklinke ist in Eingriff mit der Schloßfalle bringbar, um die Schloßfalle in der Hauptschloßstellung zu halten. Die zweite Sperrklinke ist mit der ersten Sperrklinke in Eingriff bringbar, um diese in ihrer Haltestellung zu halten. Die erste Sperrklinke ist mit einer für diesen Zweck überdimensionierten Feder in Richtung ihrer Haltestellung belastet.While maintaining the basic concept described, a reduction in the friction force or the friction work is only possible to a limited extent without endangering the operational safety of the motor vehicle lock. This leads to a loss of comfort due to high actuation forces in a mechanically actuated motor vehicle lock. If the motor vehicle lock is equipped with a motorized opening drive, then this opening drive is corresponding designed for high forces or performance. This leads to high space requirements and high costs.
A known motor vehicle lock (DE 102 36 282 A1) shows an approach to reducing the force required to lift the pawl. This shows a pawl arrangement consisting of two pawls. The first pawl can be brought into engagement with the lock latch to hold the lock latch in the main lock position. The second pawl can be brought into engagement with the first pawl in order to hold it in its holding position. The first pawl is loaded with an oversized spring for this purpose in the direction of its stop position.

Nachteilig an diesem Kraftfahrzeugschloß ist, daß die Bewegung der Sperrklinken sehr genau aufeinander abgestimmt sein muß, damit ein Zurückschlagen der Fahrzeugtür beim Schließen, verursacht durch eine zu langsame Bewegung der ersten Sperrklinke, verhindert wird. Diese notwendige Abstimmung der Sperrklinken aufeinander macht den Aufbau des Kraftfahrzeugschlosses kompliziert. Die Abstimmung der Sperrklinken aufeinander erfolgt mittels einer Feder mit hoher Steifigkeit. Dies führt jedoch wiederum dazu, daß die Betätigungskräfte zum Ausheben der Sperrklinke erhöht sind. Die zum Ausheben der Sperrklinke erforderliche Kraft ist durch die Verringerung der Reibkraft zwar verringert, diese Verringerung wird jedoch zumindest teilweise durch die hohe Steifigkeit der Feder wieder zunichte gemacht.A disadvantage of this motor vehicle lock is that the movement of the pawls has to be coordinated very precisely with one another so that the vehicle door is prevented from swinging back when closing, caused by the slow movement of the first pawl. This necessary matching of the pawls to each other complicates the structure of the motor vehicle lock. The pawls are matched to one another by means of a spring with high rigidity. However, this in turn means that the actuating forces for lifting the pawl are increased. The force required to lift the pawl is reduced by the reduction in the frictional force, but this reduction is at least partially canceled out by the high rigidity of the spring.

Einen weiteren Ansatz zur Reduzierung der zum Ausheben der Sperrklinke erforderlichen Kraft zeigt das bekannte Kraftfahrzeugschloß (EP 0 406 777 B1), von dem die vorliegende Erfindung ausgeht. Hier ist eine Sperrklinkenanordnung vorgesehen, die wie die oben beschriebene Sperrklinke in Eingriff mit der Schloßfalle bringbar ist, um die Schloßfalle in der Hauptschließstellung zu halten. Dabei besteht die Sperrklinkenanordnung aus einem ersten Hebel, an den ein zweiter Hebel schwenkbar angelenkt ist. Der zum Halten der Schloßfalle notwendige Eingriff zwischen der Sperrklinkenanordnung einerseits und der Schloßfalle anderseits erfolgt über den zweiten Hebel. Zur Freigabe der Schloßfalle wird der erste Hebel verschwenkt, was zu einem Verschwenken des zweiten Hebels relativ zum ersten Hebel führt. Gleichzeitig rollt der zweite Hebel gewissermaßen auf der Schloßfalle ab, bis ein instabiler Zustand entsteht und die Schloßfalle in ihre Offenstellung schwenkt. Reibarbeit kann durch das Verschwenken des zweiten Hebels bei der Freigabe der Schloßfalle weitgehend vermieden werden.The known motor vehicle lock (EP 0 406 777 B1), from which the present invention is based, shows a further approach to reducing the force required to lift the pawl. Here, a pawl arrangement is provided which, like the pawl described above, can be brought into engagement with the lock latch in order to hold the lock latch in the main closed position. The pawl arrangement consists of a first lever, to which a second lever is pivoted. The engagement between the pawl arrangement, on the one hand, and the lock latch, on the other hand, required to hold the lock latch is carried out via the second lever. To release the lock latch, the first lever is pivoted, which leads to a pivoting of the second lever relative to the first lever. At the same time, the second lever rolls, so to speak, on the lock latch until an unstable state arises and the lock latch swings into its open position. Rubbing can be done by swiveling the second lever when releasing the lock latch largely avoided.

Problematisch ist bei dem oben genannten Kraftfahrzeugschloß allerdings die Tatsache, daß die Betriebssicherheit bei in Hauptschließstellung befindlicher Schloßfalle nicht hinreichend gewährleistbar ist. Bei hohen äußeren Beschleunigungen kann es sein, daß sich der zweite Hebel verschwenkt und zu einer ungewünschten Freigabe der Schloßfalle führt. Um eine hohe Betriebssicherheit zu erreichen, wäre eine hohe Vorspannung des zweiten Hebels gegen den ersten Hebel erforderlich, was wiederum zu einer hohen zur Freigabe der Schloßfalle erforderlichen Kraft führt.The problem with the motor vehicle lock mentioned above, however, is the fact that operational safety cannot be adequately guaranteed when the lock latch is in the main locking position. At high external accelerations, the second lever may pivot and lead to an undesired release of the lock latch. In order to achieve a high level of operational security, a high preload of the second lever against the first lever would be required, which in turn leads to a high force required to release the lock latch.

Der vorliegenden Erfindung liegt das Problem zugrunde, das bekannte Kraftfahrzeugschloß derart auszugestalten und weiterzubilden, daß bei hoher Betriebssicherheit die für Freigabe der Schloßfalle aufzubringende Kraft bzw. Arbeit auf ein Minimum reduziert wird.The present invention is based on the problem of designing and developing the known motor vehicle lock in such a way that the force or work to be released for releasing the lock latch is reduced to a minimum with high operational reliability.

Das vorliegende Problem wird bei einem Kraftfahrzeugschloß mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The present problem is solved in a motor vehicle lock with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.

Wesentlich ist zunächst, daß die Rückstellung der Schloßfalle aus der Hauptschließstellung heraus in Richtung der Offenstellung die Verstellung einer Sperrklinkenkinematik der Sperrklinkenanordnung bewirkt. Bei in Haltestellung befindlicher Sperrklinkenanordnung blockiert ein verstellbares Blockierelement der Sperrklinkenanordnung die durch die Schloßfalle bewirkbare Verstellung der Sperrklinkenkinematik und damit die Rückstellung der Schloßfalle.It is essential first of all that the return of the lock latch from the main closed position in the direction of the open position causes the adjustment of a pawl kinematics of the pawl arrangement. When the pawl arrangement is in the holding position, an adjustable blocking element of the pawl arrangement blocks the adjustment of the pawl kinematics that can be effected by the lock latch and thus the resetting of the lock latch.

Der Begriff "Sperrklinkenkinematik" ist vorliegend umfassend als ein beliebiger Mechanismus zu verstehen, der zwischen die Schloßfalle und das Blockierelement geschaltet ist. Bei entsprechender Auslegung der Sperrklinkenkinematik läßt sich damit die zur Freigabe der Schloßfalle notwendige Kraft, nämlich die Kraft zur Verstellung des Blockierelements, reduzieren.The term “pawl kinematics” is to be understood comprehensively here as any mechanism that is connected between the lock latch and the blocking element. With an appropriate design of the pawl kinematics, the force required to release the lock latch, namely the force for adjusting the blocking element, can thus be reduced.

Für ein mechanisch betätigbares Kraftfahrzeugschloß ergibt sich daraus der Vorteil, daß die für die Freigabe der Schloßfalle notwendigen Betätigungskräfte gering sind und die Hebelketten von der Sperrklinkenanordnung, insbesondere vom verstellbaren Blockierelement, bis zu einem Außenbetätigungshebel bzw. bis zu einem Innenbetätigungshebel vergleichsweise schwach ausgelegt werden können. Durch die geringen Betätigungskräfte lassen sich hier auch Kunststoffmaterialien vorteilhaft einsetzen. Dies betrifft auch Verbindungselemente wie Seilzüge oder Stangen zu einem Türaußengriff oder zu einen Türinnengriff sowie den Türaußengriff oder den Türinnengriff selbst.For a mechanically actuated motor vehicle lock, this results in the advantage that the actuation forces required for releasing the lock latch are low and the lever chains can be designed to be comparatively weak from the pawl arrangement, in particular from the adjustable blocking element, to an external actuation lever or to an internal actuation lever. Due to the low actuation forces, plastic materials can also be used advantageously. This also applies to connecting elements such as cables or rods to an outside door handle or to an inside door handle as well as the outside door handle or the inside door handle itself.

Es gibt eine Vielzahl von Möglichkeiten, die genannte Lehre der Erfindung auszugestalten und weiterzubilden. Dazu darf auf die Unteransprüche verwiesen werden.There are a multitude of possibilities for embodying and developing the above-mentioned teaching of the invention. For this purpose, reference may be made to the subclaims.

Mit der Ausgestaltung der Sperrklinkenkinematik als Untersetzungsgetriebe gemäß Anspruch 2 läßt sich die vom Blockierelement aufzubringende Blockierkraft auf einfache Weise reduzieren. Durch die geringe Blockierkraft ist auch eine nur geringe Überdeckung zwischen dem Blockierelement und dem jeweiligen zu blockierenden Element der Sperrklinkenkinematik notwendig. Durch die resultierende Reduzierung des Verstellwegs des Blockierelements kann die für die Freigabe der Schloßfalle aufzubringende Arbeit weiter reduziert werden.With the design of the pawl kinematics as a reduction gear according to claim 2, the blocking force to be applied by the blocking element can be reduced in a simple manner. Due to the low blocking force, only a slight overlap between the blocking element and the respective element of the pawl kinematics to be blocked is necessary. As a result of the resulting reduction in the adjustment path of the blocking element, the work to be performed to release the lock latch can be further reduced.

Besonders vorteilhaft ist die erfindungsgemäße Lösung für ein Kraftfahrzeugschloß mit einem motorischen Öffnungsantrieb gemäß Anspruch 3. Durch die Reduzierung der für die Freigabe der Schloßfalle aufzubringenden Kraft bzw. Arbeit ist hier ein Antrieb mit nur geringer Leistung und entsprechend mit geringen Betätigungsströmen erforderlich. Ferner ist es nunmehr bei elektrischer Betätigung möglich, die Betätigungszeiten auch bei Antrieben mit geringer Leistung zu reduzieren.The solution according to the invention for a motor vehicle lock with a motorized opening drive is particularly advantageous. By reducing the force or work to be released for the release of the lock latch, a drive with only low power and correspondingly with low actuation currents is required here. Furthermore, with electrical actuation, it is now possible to reduce the actuation times even with drives with low power.

Ferner ist es bei der oben genannten elektrischen Betätigung nun ohne weiteres möglich, die motorische Freigabe der Schloßfalle sowohl im Normalbetrieb bei geringen Dichtungsgegendrücken sowie im Notbetrieb bei hohen Türgegenkräften (Crashfall) zu gewährleisten, da die für die Freigabe der Schloßfalle aufzubringende Kraft bei entsprechender Auslegung der Sperrklinkenkinematik entsprechend reduzierbar ist.Furthermore, with the above-mentioned electrical actuation, it is now easily possible to ensure the motorized release of the lock latch both in normal operation with low sealing counterpressures and in emergency operation with high door counter forces (crash event), since the force to be released for the release of the lock latch is appropriately designed Pawl kinematics can be reduced accordingly.

Die besonders bevorzugte Ausgestaltung gemäß Anspruch 4 führt dazu, daß die Schloßfalle mit dem Zwischenhebel und dem Übertragungshebel ein Viergelenk bildet, mit dem weitgehend beliebige Untersetzungsverhältnisse, die gemäß Anspruch 5 in Abhängigkeit von der Stellung der Schloßfalle veränderbar sein können, einstellbar sind. Mit dieser einfachen Einstellbarkeit der Untersetzung, insbesondere mit der veränderbaren Untersetzung in Abhängigkeit von der Stellung der Schloßfalle, läßt sich die Sperrklinkenanordnung optimal auf den jeweiligen Anwendungsfall anpassen.The particularly preferred embodiment according to claim 4 leads to the lock latch forming a four-bar linkage with the intermediate lever and the transmission lever, with which largely any reduction ratios, which can be changeable depending on the position of the lock latch, can be adjusted. With this simple adjustability of the reduction, in particular with the variable reduction depending on the position of the lock latch, the pawl arrangement can be optimally adapted to the respective application.

Durch die schwenkbare Anlenkung des Zwischenhebels an die Schloßfalle entfällt die Notwendigkeit des direkten blockierenden Eingriffs zwischen der Sperrklinkenanordnung und der Schloßfalle. Dadurch ergibt sich eine bessere Zerreißfestigkeit des Kraftfahrzeugschlosses insbesondere in Richtung der Fahrzeuglängsachse, wenn hohe Kräfte senkrecht zur Flachseite der Schloßfalle wirken. Durch die schwenkbare Anlenkung des Zwischenhebels an die Schloßfalle ist ein Vorbeirutschen der Schloßfalle am Blockierelement weitgehend ausgeschlossen. Grundsätzlich gilt diese Überlegung auch im Hinblick auf die Zerreißfestigkeit des Kraftfahrzeugschlosses quer zur Fahrzeuglängsachse.The pivotable articulation of the intermediate lever to the lock latch eliminates the need for direct blocking engagement between the pawl arrangement and the lock latch. This results in better tensile strength of the motor vehicle lock, in particular in the direction of the vehicle longitudinal axis, when high forces act perpendicular to the flat side of the lock latch. The pivotable linkage of the intermediate lever to the lock latch largely prevents the lock latch from sliding past the blocking element. In principle, this consideration also applies to the tensile strength of the motor vehicle lock transverse to the longitudinal axis of the vehicle.

Ferner kann dadurch, daß der Zwischenhebel schwenkbar an der Schloßfalle angelenkt ist, die Oberfläche der Schloßfalle weitgehend beliebig gestaltet sein. Eine besonders harte Oberfläche der Schloßfalle ist nicht erforderlich. Dies führt zur Möglichkeit der Ausgestaltung der Oberfläche der Schloßfalle im Hinblick auf eine optimale Zerreißfestigkeit sowie zu geringen Kosten.Furthermore, the fact that the intermediate lever is pivotally articulated on the lock latch, the surface of the lock latch can be designed largely arbitrarily. A particularly hard surface of the lock latch is not necessary. This leads to the possibility of designing the surface of the lock latch with a view to optimum tear resistance and at low cost.

Es darf darauf hingewiesen werden, daß in allen Ausführungsbeispielen durch die erfindungsgemäße Lösung eine Gewichtsreduzierung möglich ist, sei es, daß leichtere Kunststoffwerkstoffe verwendbar sind, sei es, daß bestimmte Komponenten weniger "massiv" auszulegen sind oder sei es, daß kleinere Antriebe verwendbar sind.It may be pointed out that in all of the exemplary embodiments, the solution according to the invention can reduce the weight, be it that lighter plastic materials can be used, be it that certain components are designed to be less "solid" or be it that smaller drives can be used.

Die Fig. 1 bis 4 zeigen ausschnittsweise ein Kraftfahrzeugschloß mit einer einen Schließkloben 1 haltenden Schloßfalle 2 und einer Sperrklinkenanordnung 3. Die Schloßfalle 2 ist um eine Schwenkachse 4 verschwenkbar und läßt sich in die in Fig. 3 dargestellte Offenstellung sowie in die in Fig. 1 dargestellte Hauptschließstellung bringen. Für die Begrenzung der Schwenkbewegung der Schloßfalle 2 beim Schließvorgang ist ferner ein ortsfester Anschlag 2a vorgesehen. Bei Seitentürschlössern ist es vorzugsweise vorgesehen, daß die Schloßfalle 2 zusätzlich in eine Vorschließstellung bringbar ist (Fig. 2). Die Sperrklinkenanordnung 3 ist in eine in Fig. 1 und in Fig. 2 dargestellte Haltestellung sowie in eine in Fig. 3 dargestellte Freigabestellung bringbar. Die in der Haltestellung befindliche Sperrklinkenanordnung 3 hält die Schloßfalle 2 in der Hauptschließstellung und, soweit vorgesehen, in der Vorschließstellung. Dabei kann es sein, daß die Sperrklinkenanordnung 3 zum Halten der Schloßfalle 2 in der Hauptschließstellung in eine erste Haltestellung bringbar ist und zum Halten der Schloßfalle 2 in der Vorschließstellung in eine zweite Haltestellung bringbar ist. Es kann aber auch sein, daß nur eine einzige Haltestellung vorgesehen ist.1 to 4 show sections of a motor vehicle lock with a lock latch 2 holding a locking bolt 1 and a pawl arrangement 3. The lock latch 2 can be pivoted about a pivot axis 4 and can be moved into the open position shown in FIG. 3 and into the position shown in FIG. 1 bring the main closing position shown. A stationary stop 2a is also provided to limit the pivoting movement of the lock latch 2 during the closing process. In the case of side door locks, it is preferably provided that the lock latch 2 can additionally be brought into a pre-closing position (FIG. 2). The pawl arrangement 3 can be brought into a holding position shown in FIG. 1 and in FIG. 2 and into a release position shown in FIG. 3. The pawl arrangement 3 in the holding position holds the lock latch 2 in the main closed position and, if provided, in the pre-closed position. It may be the case that the pawl arrangement 3 can be brought into a first holding position for holding the lock latch 2 in the main closing position and can be brought into a second holding position for holding the lock latch 2 in the pre-closing position. But it can also be the case that only a single stop position is provided.

Wesentlich ist, daß die Sperrklinkenanordnung 3 eine Sperrklinkenkinematik 5 und ein verstellbares Blockierelement 6 aufweist. Durch eine Kopplung zwischen der Schloßfalle 2 und der Sperrklinkenkinematik 5 bewirkt die Rückstellung der Schloßfalle 2 aus der in Fig. 1 dargestellten Hauptschließstellung heraus in Richtung der in Fig. 3 dargestellten Offenstellung eine entsprechende Verstellung der Sperrklinkenkinematik 5. Wenn sich die Sperrklinkenanordnung 3, wie in Fig. 1 dargestellt, in der Haltestellung befindet, so blockiert das Blockierelement 6 die durch die Schloßfalle 2 bewirkbare Verstellung der Sperrklinkenkinematik 5 und damit die Rückstellung der Schloßfalle 2. Die Vorteile einer derartigen Ausgestaltung der Sperrklinkenanordnung 3 wurden im allgemeinen Teil der Beschreibung bereits erläutert.It is essential that the pawl arrangement 3 has a pawl kinematics 5 and an adjustable blocking element 6. Through a coupling between the lock latch 2 and the pawl kinematics 5, the return of the lock latch 2 from the main closing position shown in FIG. 1 in the direction of the open position shown in FIG. 3 results in a corresponding adjustment of the pawl kinematics 5. As shown in FIG. 1, in the holding position, the blocking element 6 blocks the adjustment of the pawl kinematics 5 which can be effected by the lock latch 2 and thus the resetting of the lock latch 2. The advantages of such a configuration of the pawl arrangement 3 have already been described in the general part of the description explained.

In besonders bevorzugter Ausgestaltung ist die Sperrklinkenkinematik 5 als Untersetzungsgetriebe ausgestaltet, so daß die vom Blockierelement 6 zur Blockierung der Schloßfalle 2 aufzubringende Blockierkraft entsprechend der Auslegung des Untersetzungsgetriebes reduziert ist. Mit dem Begriff "Untersetzungsgetriebe" ist vorliegend gemeint, daß der Betrag der von der Schloßfalle 2 auf die Sperrklinkenkinematik 5 wirkenden Rückstellkraft größer ist als die resultierende von der Sperrklinkenkinematik 5 auf das Blockierelement 6 wirkende Kraft.In a particularly preferred embodiment, the pawl kinematics 5 is designed as a reduction gear, so that the blocking force to be applied by the blocking element 6 to block the lock latch 2 is reduced in accordance with the design of the reduction gear. In the present case, the term "reduction gear" means that the amount of the restoring force acting on the latch mechanism 5 from the latch 2 is greater than the resulting force acting on the blocking element 6 from the latch mechanism 5.

Es wurde ebenfalls im allgemeinen Teil der Beschreibung erläutert, daß die Ausgestaltung des Kraftfahrzeugschlosses mit einem motorischen Öffnungsantrieb in Verbindung mit der beschriebenen Sperrklinkenanordnung 3 besonders vorteilhaft ist. Dabei ist die Freigabe der Schloßfalle 2 dadurch auslösbar, daß ein nicht weiter dargestellter Öffnungsantrieb eine Verstellung des Blockierelements 6 von der blockierenden Stellung in die in Fig. 1 gestrichelt dargestellte, nicht blockierende Stellung bewirkt. Vorzugsweise handelt es sich bei dem Öffnungsantrieb um einen Elektromotor.It was also explained in the general part of the description that the configuration of the motor vehicle lock with a motorized opening drive in connection with the described pawl arrangement 3 is particularly advantageous. The release of the lock latch 2 can be triggered in that an opening drive (not shown) causes the blocking element 6 to be moved from the blocking position into the non-blocking position shown in broken lines in FIG. 1. The opening drive is preferably an electric motor.

Im dargestellten und insoweit bevorzugten Ausführungsbeispiel weist die Sperrklinkenkinematik 5 einen um eine Schwenkachse 7 schwenkbaren Übertragungshebel 8 auf. Durch die Rückstellung der Schloßfalle 2 aus der Hauptschließstellung heraus in Richtung der Offenstellung, in Fig. 1 rechtsherum, ist der Übertragungshebel 8, in Fig. 1 rechtsherum, verstellbar. Bei in Haltestellung befindlicher Sperrklinkenanordnung 3 blockiert das Blockierelement 6 den Übertragungshebel 8, so daß im Ergebnis auch die Rückstellung der Schloßfalle 2 blockiert wird.In the illustrated and preferred embodiment, the pawl kinematics 5 has a transmission lever 8 which can be pivoted about a pivot axis 7. By resetting the lock latch 2 from the main closed position in the direction of the open position, to the right in FIG. 1, the transmission lever 8 is adjustable to the right in FIG. 1. When the pawl arrangement 3 is in the holding position, the blocking element 6 blocks the transmission lever 8, so that, as a result, the reset of the lock latch 2 is also blocked.

Eine besonders einfache, mit wenigen Bauteilen realisierbare Ausgestaltung des oben genannten Prinzips zeigt Fig. 5 in schematischer Darstellung. Der Übertragungshebel 8 ist hier einerseits mit dem Blockierelement 6 und andererseits mit der Schloßfalle 2 in Eingriff bringbar. Fig. 5 zeigt die Schloßfalle 2 in Hauptschließstellung und die Sperrklinkenanordnung 3 in Haltestellung.A particularly simple embodiment of the above-mentioned principle that can be implemented with a few components is shown in a schematic illustration in FIG. 5. The transmission lever 8 is here on the one hand with the blocking element 6 and on the other hand with the lock latch 2 can be brought into engagement. Fig. 5 shows the lock latch 2 in the main closed position and the pawl arrangement 3 in the holding position.

Wird nun das Blockierelement 6 in Fig. 5 nach rechts verschwenkt, so wird die Schloßfalle 2 freigegeben. Die Rückstellung der Schloßfalle 2 aus der in Fig. 5 dargestellten Hauptschließstellung in Fig. 5 rechtsherum bewirkt dann ein Verschwenken des Übertragungshebels 8 in Fig. 5 linksherum gegen der Vorspannung der Feder 8b. Durch die an der Schloßfalle 2 angeordnete Führungsfläche 9 wird der Übertragungshebel 8 in der ausgelenkten Stellung gehalten. Durch eine weitere Führungsfläche 10 wird das Blockierelement 6 ebenfalls in der ausgelenkten Stellung gehalten. Bei der anschließenden Verstellung der Schloßfalle 2 aus der Offenstellung heraus in die Hauptschließstellung kommt das Blockierelement 6 wieder in blockierenden Eingriff mit dem Übertragungshebel 8 und hält damit die Schloßfalle 2 in der dargestellten Hauptschließstellung. Besonders vorteilhaft ist hier die Tatsache, daß der Übertragungshebel 8, der Teil der Sperrklinkenkinematik 3 ist, als Untersetzungsgetriebe ausgebildet ist, da die Schwenkachse 7 des Übertragungshebels 8 nicht mittig, sondern versetzt am Übertragungshebel 8 angeordnet ist.If the blocking element 6 is now pivoted to the right in FIG. 5, the lock latch 2 is released. The return of the lock latch 2 from the main locking position shown in FIG. 5 in FIG. 5 to the right then causes the transmission lever 8 in FIG. 5 to pivot to the left against the bias of the spring 8b. The transmission lever 8 is held in the deflected position by the guide surface 9 arranged on the lock latch 2. The blocking element 6 is also held in the deflected position by a further guide surface 10. During the subsequent adjustment of the lock latch 2 from the open position into the main closed position, the blocking element 6 comes into blocking engagement with the transmission lever 8 again and thus holds the lock latch 2 in the main closed position shown. It is particularly advantageous here that the transmission lever 8, which is part of the pawl kinematics 3, is designed as a reduction gear, since the pivot axis 7 of the transmission lever 8 is not arranged in the center, but offset on the transmission lever 8.

Es darf darauf hingewiesen werden, daß die Blockierung des Übertragungshebels 8 durch das Blockierelement 6 vorzugsweise in nur einer Schwenkrichtung des Übertragungshebels 8 vorgesehen ist. In bestimmten Anwendungsfällen kann es aber auch vorteilhaft sein, daß die Blockierung durch das Blokkierelement 6 ein Verschwenken des Übertragungshebels 8 in beiden Schwenkrichtungen verhindert.It should be pointed out that the blocking of the transmission lever 8 by the blocking element 6 is preferably provided in only one pivoting direction of the transmission lever 8. In certain applications, however, it can also be advantageous that the blocking by the blocking element 6 prevents the transmission lever 8 from pivoting in both pivoting directions.

Bei dem in den Fig. 1 bis 4 dargestellten und insoweit bevorzugten Ausführungsbeispiel ist es vorgesehen, daß der Übertragungshebel 8 mit der Schloßfalle 2 bewegungsgekoppelt ist. Hiermit ist eine Zwangskopplung zwischen dem Übertragungshebel 8 und der Schloßfalle 2 gemeint, die dazu führt, daß eine Verstellung der Schloßfalle 2 grundsätzlich zu einer entsprechenden Verstellung des Übertragungshebels 8 führt.In the exemplary embodiment shown in FIGS. 1 to 4 and so far preferred, it is provided that the transmission lever 8 is coupled in motion with the lock latch 2. This means a forced coupling between the transmission lever 8 and the lock latch 2, which means that an adjustment of the lock latch 2 basically leads to a corresponding adjustment of the transmission lever 8.

In bevorzugter Ausgestaltung ist zur oben genannten Bewegungskopplung ein Zwischenhebel 11 zwischen dem Übertragungshebel 8 und der Schloßfalle 2 angeordnet, der an der Schloßfalle 2 einerseits und am Übertragungshebel 8 andererseits schwenkbar angelenkt ist. Der Anlenkpunkt 12 an der Schloßfalle 2 ist bezüglich der Schwenkachse 4 der Schloßfalle 2 exzentrisch, also von der Schwenkachse 4 beabstandet, angeordnet. Entsprechend ist der Anlenkpunkt 13 am Übertragungshebel 8 bezüglich der Schwenkachse 7 des Übertragungshebels 8 exzentrisch angeordnet.In a preferred embodiment, an intermediate lever 11 is arranged between the transmission lever 8 and the lock latch 2 for the above-mentioned motion coupling, which is on the lock latch 2 on the one hand and on the transmission lever 8 on the other hand is pivotally articulated. The articulation point 12 on the lock latch 2 is arranged eccentrically with respect to the pivot axis 4 of the lock latch 2, that is to say spaced from the pivot axis 4. Accordingly, the articulation point 13 on the transmission lever 8 is arranged eccentrically with respect to the pivot axis 7 of the transmission lever 8.

Durch die oben beschriebene Kopplung zwischen Schloßfalle 2, Zwischenhebel 11 und Übertragungshebel 8 ergibt sich ein Viergelenkgetriebe, durch das sich die jeweils gewünschte Untersetzung der Sperrklinkenkinematik 5 mit geringem konstruktiven Aufwand einstellen läßt. Besonders vorteilhaft ist die Tatsache, daß sich die Untersetzung eines derartigen Viergelenkgetriebes je nach Stellung beispielsweise des Übertragungshebels 8 ändert.The coupling between the lock latch 2, the intermediate lever 11 and the transmission lever 8 described above results in a four-bar transmission, by means of which the desired reduction ratio of the pawl kinematics 5 can be set with little design effort. The fact that the reduction of such a four-bar linkage changes depending on the position of, for example, the transmission lever 8 is particularly advantageous.

Besonders anwendungsgerecht ist es, wenn die Untersetzung bei in Hauptschließstellung befindlicher Schloßfalle 2 besonders hoch ist und wenn die Untersetzung bei in Vorschließstellung befindlicher Schloßfalle 2 entsprechend niedriger ist. Dies ist insofern anwendungsgerecht, als die bei in der Hauptschließstellung befindlicher Schloßfalle 2 auftretenden Haltekräfte weitaus höher sind als bei in der Vorschließstellung befindlicher Schloßfalle 2. Der Grad der Untersetzung bei in der Hauptschließstellung befindlicher Schloßfalle 2 ist vorzugsweise bis zu achtmal größer als der Grad der Untersetzung bei in der Vorschließstellung befindlicher Schloßfalle 2. Insgesamt führt die variable Untersetzung des Viergelenks zu einer optimalen Nutzung des im Kraftfahrzeugschloß vorhandenen Bauraums.It is particularly suitable for use if the reduction is particularly high when the lock case 2 is in the main closed position and if the reduction ratio is correspondingly lower when the lock case 2 is in the closed position. This is appropriate for the application in that the holding forces that occur when the lock latch 2 is in the main closed position are far higher than when the lock latch 2 is in the closed position. The degree of reduction when the lock latch 2 is in the main closed position is preferably up to eight times greater than the degree of reduction when the lock latch 2 is in the pre-closed position. Overall, the variable reduction of the four-bar linkage leads to an optimal use of the space available in the motor vehicle lock.

Besonders vorteilhaft für die Betriebssicherheit des Kraftfahrzeugschlosses ist es, wenn bei in Hauptschließstellung und, falls vorgesehen, in Vorschließstellung befindlicher Schloßfalle 2 die von der Schloßfalle 2 über den Zwischenhebel 11 auf den Übertragungshebel 8 wirkende Kraft ein Drehmoment am Übertragungshebel 8 bezüglich dessen Schwenkachse 7 bewirkt, und wenn die Blockierkraft des Blockierelements 6 diesem Drehmoment entgegenwirkt. In der Darstellung gemäß Fig. 1 läßt sich erkennen, daß bei einer Kraftwirkung vom Schließkloben 1 auf die Schloßfalle 2 in Fig. 1 nach unten (beispielsweise bei einer Zugkraft auf eine geschlossene Seitentür) eine entsprechende Kraft von der Schloßfalle 2 über den Zwischenhebel 11 auf den Übertragungshebel 8 geleitet wird. Die Kraftwirkungslinie 14 dieser Kraft läuft durch die beiden Anlenkpunkte 12, 13.It is particularly advantageous for the operational safety of the motor vehicle lock if, when the lock latch 2 is in the main closed position and, if provided, in the lock position, the force acting on the transmission lever 8 from the lock latch 2 via the intermediate lever 11 causes a torque on the transmission lever 8 with respect to its pivot axis 7. and when the blocking force of the blocking element 6 counteracts this torque. 1 it can be seen that with a force acting from the locking block 1 on the lock latch 2 in FIG. 1 downward (for example with a tensile force on a closed side door), a corresponding force is exerted by the lock latch 2 via the intermediate lever 11 the transmission lever 8 is directed. The line of action 14 of this force runs through the two articulation points 12, 13.

Dadurch, daß die Kraftwirkungslinie 14 in Fig. 1 rechts an der Schwenkachse 7 des Übertragungshebels 8 vorbeiläuft, wird ein Drehmoment am Übertragungshebel 8 in Fig. 1 rechtsherum erzeugt. Diesem Drehmoment wirkt die Blockierkraft des Blockierelements 6 entgegen. Fig. 1 macht dabei deutlich, daß die Untersetzung desto größer wird, je näher die Kraftwirkungslinie 14 zu der Schwenkachse 7 verläuft. Man wird die beiden obigen Ziele im Sinne eines optimalen Kompromisses durch eine geeignete Beabstandung der Kraftwirkungslinie 14 zur Schwenkachse 7 miteinander verbinden.Due to the fact that the line of action 14 in FIG. 1 runs past the pivot axis 7 of the transmission lever 8 on the right, a torque is generated on the transmission lever 8 in FIG. 1 to the right. The blocking force of the blocking element 6 counteracts this torque. Fig. 1 makes it clear that the reduction is greater, the closer the line of action 14 to the pivot axis 7. The two above goals will be connected to one another in the sense of an optimal compromise by a suitable spacing of the force action line 14 from the pivot axis 7.

Dadurch, daß bei in Hauptschließstellung befindlicher Schloßfalle 2 in der Regel eine Zugkraft vom Schließkloben 1 auf die Schloßfalle 2 wirkt (Dichtungsgegendrücke), entsteht in der Regel das oben genannte Drehmoment auf den Übertragungshebel 8. Dies führt dazu, daß bei in Hauptschließstellung befindlicher Schloßfalle 2 der Übertragungshebel 8 grundsätzlich in der in Fig. 1 dargestellten Stellung steht, die durch das in der blockierenden Stellung stehende Blockierelement 6 definiert ist.The fact that when the lock latch 2 is in the main closed position usually acts as a pulling force from the locking block 1 on the lock latch 2 (sealing counterpressures) usually results in the above-mentioned torque on the transmission lever 8. This leads to the fact that when the lock latch 2 is in the main closed position the transmission lever 8 is basically in the position shown in FIG. 1, which is defined by the blocking element 6 in the blocking position.

Um bei der Freigabe der Schloßfalle 2 eine sichere Rückstellung der Schloßfalle 2 aus der Hauptschließstellung heraus in die Offenstellung gewährleisten zu können, ist es in bevorzugter Ausgestaltung vorgesehen, daß der Übertragungshebel 8 vorgespannt ist und daß die Blockierkraft des Blockierelements 6 der Vorspannung des Übertragungshebels 8 entgegenwirkt. Grundsätzlich kann diese Vorspannung auch an anderen Komponenten der Sperrklinkenkinematik 5 vorgesehen werden. Im Hinblick auf die im dargestellten Ausführungsbeispiel herrschenden Hebelverhältnisse ist es allerdings besonders vorteilhaft, wenn der Übertragungshebel 8 wie beschrieben vorgespannt ist. Die Richtung dieser Vorspannung ist in den Fig. 1 bis 4 durch den Pfeil 15 dargestellt.In order to be able to ensure a safe return of the lock latch 2 from the main closed position to the open position when the lock latch 2 is released, it is provided in a preferred embodiment that the transmission lever 8 is pretensioned and that the blocking force of the blocking element 6 counteracts the pretension of the transmission lever 8 , In principle, this preload can also be provided on other components of the pawl kinematics 5. With regard to the lever ratios prevailing in the illustrated embodiment, it is particularly advantageous if the transmission lever 8 is pretensioned as described. The direction of this bias is shown in Figs. 1 to 4 by the arrow 15.

Um die oben genannte Blockierkraft vom Blockierelement 6 auf den Übertragungshebel 8 übertragen zu können, weist der Übertragungshebel 8 in bevorzugter Ausgestaltung eine Hauptrast 16 und eine Vorrast 16a auf. Wie oben bereits erläutert wurde, kann auf eine Vorrast 16a je nach Anwendungsfall ggf. verzichtet werden. Das Blockierelement 6 ist über die Hauptrast 16, und, falls vorhanden, die Vorrast 16a in blockierenden Eingriff mit dem Übertragungshebel 8 bringbar. Dies ist in den Fig. 1 und 2 für die Hauptschließstellung und die Vorschließstellung der Schloßfalle 2 dargestellt.In order to be able to transmit the blocking force mentioned above from the blocking element 6 to the transmission lever 8, the transmission lever 8 in a preferred embodiment has a main catch 16 and a preliminary catch 16a. As already explained above, depending on the application, a preliminary catch 16a may be dispensed with. The blocking element 6 can be brought into blocking engagement with the transmission lever 8 via the main catch 16 and, if present, the preliminary catch 16a. This is shown in FIGS. 1 and 2 for the main closed position and the closed position of the lock latch 2.

Das Blockierelement 6 ist in bevorzugter Ausgestaltung nach Art einer Sperrklinke um eine Schwenkachse 17 schwenkbar. Es ist ferner ein Anschlag 6a vorgesehen, an dem das Blockierelement 6 in der blockierenden Stellung anliegt und gegen den die Vorspannung einer am Blockierelement 6 angreifenden Feder 6b wirkt. Bei in Haltestellung befindlicher Sperrklinkenanordnung 3 steht das Blokkierelement 6, wie oben beschrieben, in blockierendem Eingriff mit dem Übertragungshebel 8. Eine derartige Ausgestaltung des Blockierelements 8 nach Art einer Sperrklinke führt zu einer konstruktiv besonders einfachen Realisierung.In a preferred embodiment, the blocking element 6 can be pivoted about a pivot axis 17 in the manner of a pawl. A stop 6a is also provided, against which the blocking element 6 rests in the blocking position and against which the bias of a spring 6b acting on the blocking element 6 acts. When the pawl arrangement 3 is in the holding position, the blocking element 6 is, as described above, in blocking engagement with the transmission lever 8. Such a design of the blocking element 8 in the manner of a pawl leads to a particularly simple construction.

In besonders bevorzugter Ausgestaltung weist die Anlenkung des Zwischenhebels 11 an der Schloßfalle 2 einen Freilauf auf. Dadurch ist es möglich, daß eine Verstellung der Schloßfalle 2 aus der Hauptschließstellung heraus in eine von der Offenstellung aus gesehen jenseits der Hauptschließstellung liegende Überhubstellung möglich ist, ohne notwendigerweise eine Verstellung des Übertragungshebels 8 nach sich zu ziehen. Diese Überhubstellung der Schloßfalle 2 ist in Fig. 4 gestrichelt dargestellt. Die Überhubstellung der Schloßfalle 2 wird kurzzeitig dann eingenommen, wenn beispielsweise die Seitentür eines Kraftfahrzeugs zugeschlagen wird. Der Übertragungshebel 8 wird währenddessen gegen den Anschlag 8a in seine Überhubstellung gedrückt, so daß das Blockierelement 6 in die blockierende Stellung einfallen kann.In a particularly preferred embodiment, the articulation of the intermediate lever 11 on the lock latch 2 has a freewheel. This makes it possible for the lock latch 2 to be moved out of the main closed position into an overstroke position lying beyond the main closed position, as seen from the open position, without necessarily requiring an adjustment of the transmission lever 8. This overstroke position of the lock latch 2 is shown in dashed lines in FIG. 4. The overtravel position of the lock latch 2 is briefly assumed when, for example, the side door of a motor vehicle is slammed shut. The transmission lever 8 is pressed against the stop 8a in its overtravel position, so that the blocking element 6 can fall into the blocking position.

Der oben genannte Freilauf ist dadurch realisiert, daß die Schloßfalle 2 ein Langloch 18 und der Zwischenhebel 11 einen im Langloch 18 angeordneten Zapfen 19 aufweist. Bei der Verstellung der Schloßfalle 2 von der Hauptschließstellung in die Überhubstellung läuft der Zapfen 19 im Langloch 18, wie in Fig. 4 dargestellt.The above-mentioned freewheel is realized in that the lock latch 2 has an elongated hole 18 and the intermediate lever 11 has a pin 19 arranged in the elongated hole 18. When the lock latch 2 is moved from the main closed position into the overstroke position, the pin 19 runs in the elongated hole 18, as shown in FIG. 4.

Um eine hinreichende Kopplung zwischen Schloßfalle 2 und Sperrklinkenkinematik 5 insbesondere für die Rückstellung der Schloßfalle 2 aus der Hauptschließstellung in die Offenstellung sowie die oben bereits beschriebene Fixierung des Übertragungshebels 8 am Anschlag 8a beim Überhub der Schloßfalle 2 zu gewährleisten, und um ferner ein unkontrolliertes Laufen des Zapfens 19 im Langloch 18 zu vermeiden, ist der Zwischenhebel 11 gegen die Schloßfalle 2 derart vorgespannt, daß die Schloßfalle 2 nur gegen die Vorspannung in die Überhubstellung bringbar ist. Diese Vorspannung läßt sich durch eine Vorspannfeder 20 realisieren, wie in Fig. 1 dargestellt.In order to ensure a sufficient coupling between the lock latch 2 and pawl kinematics 5, in particular for the return of the lock latch 2 from the main closed position to the open position and the above-described fixing of the transmission lever 8 at the stop 8a when the lock latch 2 is overstroke, and also to ensure that the lock latch 2 runs uncontrolled To avoid pin 19 in the slot 18, the intermediate lever 11 is biased against the lock latch 2 such that the lock latch 2 only against the bias in the Overtravel position can be brought. This bias can be realized by a bias spring 20, as shown in Fig. 1.

Mit der erfindungsgemäßen Lösung lassen sich auch Vorteile im Hinblick auf den Diebstahlschutz erreichen. Eine bevorzugte Ausgestaltung sieht vor, daß das Kraftfahrzeugschloß einen Einlaufschlitz 21 aufweist und daß das Blockierelement 6 zum Diebstahlschutz derart im Kraftfahrzeugschloß angeordnet ist, daß das Blockierelement 6 vom Einlaufschlitz 21 aus nicht oder nur schwer erreichbar ist. Hiermit ist gemeint, daß durch das Zwischenschalten der Sperrklinkenkinematik 5 nunmehr die Möglichkeit besteht, das Blockierelement 6 dort im Kraftfahrzeugschloß anzuordnen, wo es vor unberechtigten Eingriffen vom Einlaufschlitz 21 aus geschützt ist.With the solution according to the invention, advantages in terms of theft protection can also be achieved. A preferred embodiment provides that the motor vehicle lock has an inlet slot 21 and that the blocking element 6 for theft protection is arranged in the motor vehicle lock in such a way that the blocking element 6 is difficult or impossible to reach from the inlet slot 21. This means that by interposing the pawl kinematics 5 there is now the possibility of arranging the blocking element 6 in the motor vehicle lock where it is protected against unauthorized interference from the inlet slot 21.

Ferner bietet die erfindungsgemäße Lösung auch eine besonders kompakte Realisierung einer Schließhilfe. Nach dieser Ausgestaltung ist ein nicht weiter dargestellter Schließhilfsantrieb vorgesehen, der mit dem Übertragungshebel 8 gekoppelt ist. Die Schloßfalle 2 ist dann mittels des Schließhilfsantriebs über den Übertragungshebel 8 in die Hauptschließstellung verstellbar. Die notwendige Voraussetzung hierfür ist die oben erläuterte Bewegungskopplung zwischen dem Übertragungshebel 8 und der Schloßfalle 2.Furthermore, the solution according to the invention also offers a particularly compact implementation of a locking aid. According to this embodiment, a locking auxiliary drive, not shown, is provided, which is coupled to the transmission lever 8. The lock latch 2 can then be adjusted into the main closed position by means of the auxiliary locking drive via the transmission lever 8. The necessary prerequisite for this is the above-described movement coupling between the transmission lever 8 and the lock latch 2.
