Description

Die Erfindung betrifft eine Schließsystemkomponente für ein Schließsystem gemäß dem Oberbegriff von Anspruch 1 sowie ein Schließsystem gemäß Anspruch 15.The invention relates to a locking system component for a locking system according to the preamble of claim 1 and a locking system according to claim 15.

Das in Rede stehende Schließsystem ist einem Verschlusselement eines Kraftfahrzeugs zugeordnet und stellt verschiedene Funktionen zur Verfügung, die mit der Fixierung des Verschlusselements in seiner geschlossenen Stellung im Zusammenhang stehen. Der Begriff "Verschlusselement" ist vorliegend weit zu verstehen. Er umfasst Türen, insbesondere Seitentüren, Klappen, insbesondere Heckklappen, Heckdeckel, Motorhauben, Laderaumböden o. dgl..The locking system in question is associated with a closure element of a motor vehicle and provides various functions that are related to the fixation of the closure element in its closed position. The term "closure element" is to be understood in the present case. It includes doors, in particular side doors, flaps, in particular tailgates, trunk lids, hoods, load compartment floors o. Like.

Ein obiges Schließsystem kann eine ganze Reihe unterschiedlicher Schließsystemkomponenten umfassen. Hierzu gehören ein Kraftfahrzeugschloss, das regelmässig mit einem Schließkeil o. dgl. zusammenwirkt, oder eine Schließhilfsanordnung, die der Verstellung des Verschlusselements von einer Vorschließstellung in eine Hauptschließstellung dient.An above closure system may include a variety of different closure system components. These include a motor vehicle lock, which interacts regularly with a closing wedge o. The like., Or a Schließhilfsanordnung, which serves to adjust the closure member from a Vorschließstellung in a main closed position.

Die bekannte Schließsystemkomponente ( DE 20 2008 007 719 U1 ), von der die Erfindung ausgeht, ist als Kraftfahrzeugschloss ausgestaltet. Das Kraftfahrzeugschloss ist mit einer Reihe von motorischen Komfortfunktionen ausgestattet, die jeweils auf eine Verstellung von Stellelementen, allgemeiner von Bewegungselementen, zurückgehen. Ein Beispiel für eine solche Komfortfunktion ist das motorische Ausheben der Sperrklinke des Kraftfahrzeugschlosses zum Öffnen des Verschlusselements.The known locking system component ( DE 20 2008 007 719 U1 ), from which the invention proceeds, is designed as a motor vehicle lock. The motor vehicle lock is equipped with a series of motorized comfort functions, each of which goes back to an adjustment of control elements, more generally of movement elements. An example of such a comfort function is the motorized lifting of the pawl of the motor vehicle lock for opening the closure element.

Um insbesondere die steuerungstechnische Auslegung des bekannten Kraftfahrzeugschlosses einfach zu halten, ist es dort vorgesehen, dass die motorische Verstellung im Blockbetrieb erfolgt. Dies bedeutet, dass das betreffende Bewegungselement motorisch gegen eine Prallanordnung gefahren wird, die den Bewegungsimpuls des Bewegungselements aufnimmt. Die Prallanordnung ist hier als Gummipuffer ausgestaltet, der beim Aufprall des Bewegungselements zunächst mit einer elastischen Verformung reagiert. Damit lässt sich die mechanische Belastung der hinter dem Gummipuffer liegenden Komponenten wirksam reduzieren.In particular, to keep the control technology design of the known motor vehicle lock simple, it is there provided that the motorized adjustment takes place in block operation. This means that the relevant movement element is driven by a motor against a baffle arrangement, which receives the movement impulse of the movement element. The impact arrangement is designed here as a rubber buffer, which initially reacts with elastic deformation on impact of the moving element. This effectively reduces the mechanical load on the components behind the rubber buffer.

Nachteilig bei der Verwendung der obigen Gumipuffer als Prallanordnung ist allerdings die Tatsache, dass ein solcher Gummipuffer als elastische Feder wirkt, was zu einem entsprechenden Rückfedern führt. Das Rückfedern kann zu einer Fehlpositionierung des Bewegungselements führen, nachdem es in die Prallanordnung gefahren worden ist. Ferner kann das Rückfedern eine Art Prellen verursachen, das ungewünschte Geräuscheffekte mit sich bringen kann.A disadvantage of the use of the above gum buffers as a baffle arrangement, however, is the fact that such a rubber buffer acts as an elastic spring, resulting in a corresponding springback. The springback can lead to a mispositioning of the moving element after it has been driven into the baffle arrangement. Furthermore, the springback can cause a kind of bounce that can bring about undesirable noise effects.

Entsprechendes gilt für eine bekannte, als Schließhilfsanordnung ausgestaltete Schließsystemkomponente ( DE 20 2008 007 719 U1 ).The same applies to a known closing system component configured as a closing auxiliary arrangement ( DE 20 2008 007 719 U1 ).

Der Erfindung liegt das Problem zugrunde, die bekannte Schließsystemkomponente derart auszugestalten und weiterzubilden, dass das Betriebsverhalten der Prallanordnung verbessert wird.The invention is based on the problem of designing and further developing the known locking system component in such a way that the operating behavior of the impact arrangement is improved.

Das obige Problem wird bei einer Schließsystemkomponente gemäß dem Oberbegriff von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The above problem is solved in a lock system component according to the preamble of claim 1 by the features of the characterizing part of claim 1.

Es wird vorgeschlagen, dass die Prallanordnung ein Kunststoff-Schaumelement aufweist, das zumindest zum Teil, vorzugsweise vollständig, aus einem mikrozellulären, offenporigen Kunststoffschaum, insbesondere einem Polyurethanschaum, besteht. Vorschlagsgemäß ist erkannt worden, dass mit einem solchen Kunststoffschaum nicht nur die mechanische Belastung der beteiligten Komponenten bei einem Auftreffen der Bewegungskomponente auf die Prallanordnung reduziert werden kann, sondern dass der offenporige Kunststoffschaum bei geeigneter Auslegung außerordentlich gute Dämpfungseigenschaften aufweisen kann. Dies führt dazu, dass die Bewegungsenergie des Bewegungselements zu einem beträchtlichen Teil innerhalb des Kunststoffschaums abgebaut werden kann. Ein Rückprellen des Bewegungselements nach dem Auftreffen auf dem Prallelement lässt sich so auf elegante Weise vermeiden. Nach dem Auftreffen und der damit verbundenen Verformung des Kunstoffschaums relaxiert der Kunststoffschaum je nach Auslegung relativ langsam in seine Ausgangskonstellation zurück.It is proposed that the impact arrangement comprises a plastic foam element which consists at least in part, preferably completely, of a microcellular, open-pored plastic foam, in particular a polyurethane foam. According to the proposal has been recognized that with such a plastic foam not only the mechanical stress of the components involved in a hitting the movement component can be reduced to the baffle arrangement, but that the open-cell plastic foam can have extraordinarily good damping properties with a suitable design. This results in that the kinetic energy of the moving element can be degraded to a considerable extent within the plastic foam. A rebound of the moving element after hitting the baffle element can be avoided in an elegant way. After impact and the associated deformation of the plastic foam, the plastic foam relaxes depending on the design relatively slowly back to its initial constellation.

Die vorschlagsgemäße Lösung eignet sich besonders gut für eine als Kraftfahrzeugschloss ausgestaltete Schließsystemkomponente (Anspruch 2) sowie für eine als Schließhilfsanordnung ausgestaltete Schließsystemkomponente (Anspruch 3). Dies liegt daran, dass die motorischen Komfortfunktionen dieser Komponenten nicht fortlaufend, sondern nur bei Bedarf ausgelöst werden. Die obige, relativ langsame Relaxation des Kunststoffschaums kann bei diesen bevorzugten Anwendungsfällen ohne weiteres in Kauf genommen werden.The proposed solution is particularly well suited for a designed as a motor vehicle lock locking system component (claim 2) and designed as a closing auxiliary locking system component (claim 3). This is because the motor comfort functions of these components are not triggered continuously, but only when needed. The above, relatively slow relaxation of the plastic foam can readily be accepted in these preferred applications.

Die bevorzugten Ausgestaltungen gemäß den Ansprüchen 5 bis 9 betreffen vorteilhafte Auslegungsvarianten für den Kunststoffschaum. Bei der ganz besonders bevorzugten Ausgestaltung gemäß Anspruch 5 hat sich die Verwendung des Materials PORON® als außerordentlich vorteilhaft herausgestellt. Das Material PORON® geht auf die Herstellerfirma Rogers Corporation, Connecticut, USA zurück. Mit dem PORON®-Material lassen sich ganz besonders gute Dämpfungsergebnisse erzielen. Gleichzeitig hat sich bei der vorschlagsgemäßen Verwendung als Material für eine obige Prallanordnung eine nur geringe Materialermüdung gezeigt.The preferred embodiments according to claims 5 to 9 relate to advantageous design variants for the plastic foam. In the most preferred embodiment according to claim 5, the use of the material PORON ® has proven to be extremely beneficial. The material PORON ® goes back to the manufacturer Rogers Corporation, Connecticut, USA. Very good damping results can be achieved with PORON ® material. At the same time, only limited material fatigue has been shown in the proposed use as a material for an above baffle arrangement.

In Versuchen hat sich weiter herausgestellt, dass der mikrozelluläre, offenporige Kunststoffschaum für die in Rede stehenden Anwendungen in Impulsrichtung außerordentlich dünn ausgestaltet sein kann (Anspruch 10), ohne seine Dämpfungseigenschaften nennenswert zu verlieren.In experiments it has further been found that the microcellular, open-cell plastic foam for the applications in question in the pulse direction can be designed extremely thin (claim 10), without losing its damping properties significantly.

Die besonders bevorzugte Ausgestaltung gemäß Anspruch 14 sieht in einer Variante vor, dass die Eigenelastizität des Kunststoffschaums zur Befestigung des Kunststoff-Schaumelements genutzt wird. Interessant ist, dass dies mit der vorschlagsgemäßen Lösung bei geeigneter Auslegung möglich ist, ohne dass die Dämpfungseigenschaften des Kunstsoffschaums allzu sehr in Mitleidenschaft gezogen werden.The particularly preferred embodiment according to claim 14 provides in a variant that the inherent elasticity of the plastic foam is used for fastening the plastic foam element. It is interesting that this is possible with the proposed solution with a suitable design, without the damping properties of Kunstsoffschaums are affected too much.

Nach einer weiteren Lehre nach Anspruch 15, der eigenständige Bedeutung zukommt, wird ein Schließsystem, das einem Verschlusselement eines Kraftfahrzeugs zugeordnet ist, als solches beansprucht. Das Schließsystem ist hier mit einem vorschlagsgemäßen Kraftfahrzeugschloss und/oder mit einer vorschlagsgemäßen Schließhilfsanordnung ausgestattet. Insoweit darf auf alle Ausführungen zu Kraftfahrzeugschloss und Schließhilfsanordnung verwiesen werden.According to another teaching according to claim 15, which has independent significance, a locking system associated with a closure element of a motor vehicle is claimed as such. The locking system is here equipped with a proposed motor vehicle lock and / or with a proposed closing auxiliary arrangement. In that regard may be made to all statements on motor vehicle lock and auxiliary closing arrangement.

In den Fig. 2 und 3 sind die Bewegungselemente 4a, 4b im Kraftfahrzeugschloss 1a beweglich gelagert, In Fig. 3 ist das Bewegungselement 4c unabhängig vom Kraftfahrzeugschloss 1 a beweglich.In the Fig. 2 and 3 the movement elements 4a, 4b are movably mounted in the motor vehicle lock 1a, In Fig. 3 is the moving element 4c independently of the motor vehicle lock 1 a movable.

Wesentlich ist für die vorschlagsgemäße Lehre ist, dass die Prallanordnung 3 ein Kunststoff-Schaumelement 5 aufweist, das zumindest zum Teil, vorzugsweise vollständig, aus einem mikrozellulären, offenporigen Kunststoffschaum, insbesondere einem Polyurethanschaum, besteht. Die hiermit verbundenen Vorteile, insbesondere im Hinblick auf die erzielbaren Dämpfungseigenschaften, wurden weiter oben erläutert.It is essential for the proposed teaching that the impact assembly 3 comprises a plastic foam element 5, which consists at least in part, preferably completely, of a microcellular, open-cell plastic foam, in particular a polyurethane foam. The associated advantages, in particular with regard to the achievable damping properties, have been explained above.

Wie schon angesprochen handelt es sich bei der hier in erster Linie diskutierten Schließsystemkomponente um das Kraftfahrzeugschloss 1a, das in an sich üblicher Weise mit einem Schließkeil 12 o. dgl. in haltenden Eingriff bringbar ist.As already mentioned, the locking system component discussed here in the first place is the motor vehicle lock 1a, which can be brought into holding engagement with a closing wedge 12 or the like in a conventional manner.

In einer bevorzugten, hier nicht dargestellten Variante ist eine Schließsystemkomponente in obigem Sinne als Schließhilfsanordnung ausgestaltet, mit der eine Verstellung des Verschlußelements 2 von einer Vorschließstellung in eine Hauptschließstellung bewirkbar ist. Andere Varianten für die Schließsystemkomponente sind denkbar.In a preferred variant, not shown here, a locking system component in the above sense is designed as a closing auxiliary arrangement, with which an adjustment of the closure element 2 from a prelocking position into a main closed position can be effected. Other variants for the locking system component are conceivable.

Es sind zahlreiche Möglichkeiten für die konstruktive Umsetzung der Prallanordnung 3 denkbar. Beispielsweise kann es vorgesehen sein, dass das KunststoffSchaumelement 5 der Prallanordnung 3 bei der Impulsaufnahme in unmittelbaren Eingriff mit dem jeweiligen Bewegungselement 4 bringbar ist. Dies ist bei allen dargestellten Ausführungsbeispielen daran zu erkennen, dass das jeweilige Kunststoff-Schaumelement 5 stets zum Bewegungselement 4 hin offen, und nicht etwa gekapselt, angeordnet ist.There are numerous possibilities for the constructive implementation of the impact arrangement 3 conceivable. For example, provision may be made for the plastic foam element 5 of the impact arrangement 3 to be able to be brought into direct engagement with the respective movement element 4 when the pulse is picked up. This can be seen in all illustrated embodiments of the fact that the respective plastic foam element 5 is always open to the movement element 4, and not encapsulated.

Denkbar ist aber grundsätzlich auch, dass die Prallanordnung 3 zwischen dem Kunststoff-Schaumelement 5 und dem Bewegungselement 4 eine separate Kontaktfläche bereitstellt, die bei der Impulsaufnahme in unmittelbaren Eingriff mit dem Bewegungselement 4 bringbar ist und den Bewegungsimpuls auf das Kunststoff-Schaumelement 5 leitet.It is also conceivable, however, in principle that the impact arrangement 3 between the plastic foam element 5 and the movement element 4 provides a separate contact surface, which in the pulse recording in direct engagement with the movement element 4 can be brought and directs the movement pulse to the plastic foam element 5.

Es darf darauf hingewiesen werden, dass das Kunststoff-Schaumelelement 5, wie dargestellt, einstückig ausgestaltet sein kann, was zu einer kostengünstigen Variante führt. Alternativ dazu kann das Kunststoff-Schaumelement 5 mehrstückig, insbesondere aus mehrereren Lagen von Kunststoff-Schaumelementen, ausgestaltet sein. Mit der letztgenannten Variante lässt sich das Prallverhalten durch eine geeignete Wahl der einzelnen Lagen besonders genau einstellen.It may be pointed out that the plastic foam element 5, as shown, can be designed in one piece, which leads to a cost-effective variant. Alternatively, the plastic foam element 5 may be designed in several pieces, in particular from a plurality of layers of plastic foam elements. With the last-mentioned variant, the impact behavior can be set particularly precisely by a suitable choice of the individual layers.

Besonders gute Erfahrungen sind mit der vorschlagsgemäßen Lösung gemacht worden, wenn das Kunststoff-Schaumelementmaterial als PORON®-Material ausgelegt worden ist. Die trifft, wie oben erläutert, insbesondere für das erzielbare Dämpfungsverhalten zu. Als bevorzugt hat sich vor allem das PORON®-Material 4790-92 (Produktbezeichnung der Rogers Corporation) herausgestellt. Weiter bevorzugt sind die PORON®-Materialien 4701-30, 4701-40 und 4701-41.Particularly good experiences have been made with the proposed solution, when the plastic foam element material has been designed as PORON ® material. This applies, as explained above, especially for the achievable damping behavior. As preferred above all the PORON ® material 4790-92 (product of Rogers Corporation) has been found. More preferably, the PORON ® materials 4701-30, 4701-40 and 4701-41.

Die Porengröße der Poren eines bevorzugten Kunststoff-Schaumelementmaterials liegt zwischen etwa 3µm und etwa 500µm, vorzugsweise zwischen etwa 10µm und etwa 70µm, vorzugsweise bei etwa 40µm.The pore size of the pores of a preferred plastic foam element material is between about 3 microns and about 500 microns, preferably between about 10 microns and about 70 microns, preferably about 40 microns.

Ferner hat sich ein Kunststoffschaum für die Anwendung mit der vorschlagsgemäßen Lösung bewährt, dessen Dichte, gemessen nach ASTDM D 3574-95 Test A, in einem Bereich zwischen etwa 200 kg/m3 und 440 kg/m3 liegt.Furthermore, a plastic foam for use with the proposed solution has proven its density, measured according to ASTM D 3574-95 Test A, in a range between about 200 kg / m 3 and 440 kg / m 3 .

Dabei liegt die Härte (Shore "O") des Kunststoffschaums, gemessen mit Durometer nach ASTM D 2240-97, vorzugsweise zwischen etwa 1,5 und etwa 70, weiter vorzugsweise zwischen etwa 1,5 und etwa 4, weiter vorzugsweise bei etwa 2.The hardness (Shore "O") of the plastic foam, measured by durometer according to ASTM D 2240-97, is preferably between about 1.5 and about 70, more preferably between about 1.5 and about 4, more preferably about 2.

Das Dämpfungsverhalten spiegelt sich am besten an der Ermittlung der sogenannten Rückverformung, gemessen mit einem Resiliometer nach ASTM D 2632 (vertikaler Abprall), wider. Die englische Bezeichnung hierfür ist "Resilience by vertical Rebound". Die so gemessene Rückverformung liegt vorzugsweise zwischen etwa 3% und etwa 9%, vorzugsweise zwischen etwa 4% und etwa 8% und weiter vorzugsweise bei etwa 4,5%. Diese geringen Werte machen deutlich, dass bei einer solchen Auslegung ein eingangs erwähntes Prellverhalten kaum auftreten kann.The damping behavior is best reflected in the determination of the so-called rebound, measured with a Resiliometer according to ASTM D 2632 (vertical rebound). The English term for this is "Resilience by vertical rebound". The recovery measured in this way is preferably between about 3% and about 9%, preferably between about 4% and about 8% and more preferably about 4.5%. Do these low values it is clear that with such a design, a bouncing behavior mentioned at the outset can hardly occur.

Es wurde schon darauf hingewiesen, dass der vorschlagsgemäße Kunststoffschaum nach seiner Verformung relativ langsam in seine Ausgangskonstellation relaxiert. Bei einer bevorzugten Variante erfolgt die Relaxation nach einer Verformung um 50% in einem Zeitbereich zwischen 0,1s und 2s. Dies ist bei dem in Rede stehenden Anwendungsfall ohne weiteres akzeptabel.It has already been pointed out that the proposed plastic foam relaxes relatively slowly into its starting constellation after it has been deformed. In a preferred variant, the relaxation occurs after deformation by 50% in a time range between 0.1s and 2s. This is readily acceptable in the case in question.

Überraschenderweise lassen sich die vorschlagsgemäßen Kunstsoffschäume bei gutem Dämpfungsverhalten sehr dünn in Impulsrichtung auslegen. Vorzugsweise ist die Dicke des Kunststoff-Schauemelements 5 in Impulsrichtung geringer als 6mm, vorzugsweise geringer als 5mm, weiter vorzugsweise geringer als 3mm.Surprisingly, the proposed Kunstsoffschäume can interpret very thin in pulse direction with good damping behavior. Preferably, the thickness of the plastic Schauemelements 5 in the pulse direction is less than 6mm, preferably less than 5mm, more preferably less than 3mm.

Das mit dem vorschlagsgemäßen Kunststoffschaum erzielbare Dämpfungsverhalten lässt sich in seiner vollen Breite nutzen, wenn die Prallanordnung 3 einen Blockieranschlag, insbesondere einen Endanschlag, für das Bewegungselement 4 bildet. Dies ist bei allen dargestellten Ausführungsformen der Fall.The achievable with the proposed plastic foam damping behavior can be used in its full width when the baffle assembly 3 forms a blocking stop, in particular an end stop for the moving element 4. This is the case in all illustrated embodiments.

Beispielsweise könnte das Bewegungselement 4 ein manuell oder motorisch verstellbarer Hebel sein, wobei die Prallanordnung 3 dann einen Blockieranschlag für den Hebel bereitstellen würde. Ein solcher Hebel könnte beispielsweise ein Zentralverriegelungshebel des Kraftfahrzeugschlosses 1a sein.For example, the moving element 4 could be a manually or motor-adjustable lever, wherein the baffle arrangement 3 would then provide a blocking stop for the lever. Such a lever could for example be a central locking lever of the motor vehicle lock 1a.

In einer bevorzugten, in Fig. 3 gezeigten Alternative ist das Kraftfahrzeugschloss 1a mit den Schließelementen Schlossfalle 6 und Sperrklinke 7 , sowie vorzugsweise mit einem der Sperrklinke 7 zugeordneten Öffnungshilfsantrieb 8 ausgestattet. Grundsätzlich kann es sich auch um eine manuell aushebbare Sperrklinke 7 handeln. Die Sperrklinke 7 bildet in beiden Fällen ein oben angesprochenes Bewegungselement 4a. Hier und vorzugsweise ist der Öffnungshilfsantrieb 8 ein Seilantrieb mit einem Antriebsseil 9, dass gegen impulsartige Kraftwirkungen zu schützen ist. Hierfür ist der Sperrklinke 7 die Prallanordnung 3a zugeordnet, auf die die Sperrklinke 7 beim Erreichen ihrer ausgehobenen Stellung mit einem Anschlag 7a trifft. Mit der vorschlagsgemäßen Lösung kann wie erläutert das Rückprellen verhindert werden, was mit einer entsprechenden Schonung des Antriebsseils 9 verbunden ist.In a preferred, in Fig. 3 Alternative shown is the motor vehicle lock 1a with the closing elements latch 6 and pawl 7, and preferably equipped with a pawl 7 associated with the auxiliary opening drive 8. In principle, it may also be a manually liftable pawl 7. The pawl 7 forms in both cases an above-mentioned movement element 4a. Here and preferably, the auxiliary opening drive 8 is a cable drive with a drive cable 9 that is to protect against pulse-like force effects. For this purpose, the pawl 7 is associated with the baffle arrangement 3a, to which the pawl 7 strikes upon reaching its raised position with a stop 7a. With the proposed solution, as explained, the rebounding can be prevented, which is associated with a corresponding protection of the drive cable 9.

Fig. 2 zeigt eine Anordnung mit einem motorisch verstellbaren Stellelement 10, das ebenfalls ein Bewegungselement 4b in obigem Sinne bereitstellt. Dem Stellelement 10 ist eine Prallanordnung 3b zugeordnet, die wiederum einen Blockieranschlag, hier einen beidseitigen Blockieranschlag, für das Stellelement 10 bereitstellt. Dafür ist das Stellelement 10 mit zwei Anschlagflächen 10a, 10b ausgestattet. Hier ist durch den Wegfall des Rückprellens die genaue Positionierbarkeit im Blocketrieb von besonderem Vorteil. Das Stellelement 10 kann beispielsweise Bestandteil eines Zentralverriegelungsantiebs für das Kraftfahrzeugschloss 1a sein. Fig. 2 shows an arrangement with a motor-adjustable actuator 10, which also provides a moving member 4b in the above sense. The control element 10 is associated with a baffle arrangement 3b, which in turn provides a blocking stop, here a two-sided blocking stop, for the actuating element 10. For this, the actuator 10 is provided with two stop surfaces 10a, 10b. Here is the absence of bounce the exact positioning in block mode of particular advantage. The actuator 10 may be part of a Zentralverriegelungsantiebs for the motor vehicle lock 1a, for example.

Fig. 4 zeigt das Einlaufmaul 11 des Kraftfahrzeugschlosses. Das Einlaufmaul 11 dient dem Einlaufen eines Schließkeils 12, der in Eingriff mit der oben angesprochenen Schloßfalle 6 bringbar ist. Der Schließkeil 12 ist üblicherweise karosseriefest angeordnet, und kommt erst beim Schließen des Verschlusselements 2 in Eingriff mit dem Kraftfahrzeugschloss 1a, insbesondere mit der Schloßfalle 6. Interessant bei dem in Fig. 4 gezeigten Ausführungsbeispiel ist die Tatsache, dass es sich beim Schließkeil 12 um ein Bewegungselement 4c im obigen Sinne handelt. Dem Schließkeil 12 ist eine Prallanordnung 3c zugeordnet, die sich an einem Ende des Einlaufinauls 11 befindet. Die Prallanordnung 3c stellt eine Dämpfungsaufnahme für den Schließkeil 11 bereit, wenn der Schließkeil 12 das Einlaufmaul 11 durchlaufen hat. Fig. 4 shows the inlet mouth 11 of the motor vehicle lock. The inlet mouth 11 serves to shrink a closing wedge 12, which can be brought into engagement with the above-mentioned latch 6. The closing wedge 12 is usually arranged fixed to the body, and comes only when closing the closure element 2 into engagement with the motor vehicle lock 1a, in particular with the latch 6. Interesting in the Fig. 4 the embodiment shown is the fact that it is the closing wedge 12 is a moving element 4c in the above sense. The striker 12 is associated with a baffle arrangement 3 c, which is located at one end of the inlet inlet 11. The baffle arrangement 3c provides a damping absorption for the closing wedge 11 when the closing wedge 12 has passed through the inlet opening 11.

Von besonderer Bedeutung ist vorliegend die Befestigung des KunststoffSchaumelements 5 derart, dass die Montage einfach und die Betriebssicherheit hoch ist. Eine bevorzugte Variante ist das Kleben des KunststoffSchaumelements 5. Eine andere Variante geht auf ein Klemmen des KunststoffSchaumelements 5 zurück. Das Kunststoff-Schaumelement kann auch vorteilhafterweise in einer insbesondere taschenartigen Ausformung zumindest zum Teil formschlüssig aufgenommen sein.Of particular importance in the present case, the attachment of the plastic foam element 5 such that the assembly is simple and the reliability is high. A preferred variant is the gluing of the plastic foam element 5. Another variant is based on a clamping of the plastic foam element 5. The plastic foam element can also advantageously be received in a form-fitting manner, in particular in a pocket-like shape, at least in part.

Besonders kostengünstig und gleichzeitig robust ist eine Variante, bei der das Kunststoff-Schaumelement 5 durch seine Eigenelastizität an der Schließsystemkomponente 1a im Übrigen befestigt ist. Bei dem in Fig. 2 dargestellten und insoweit bevorzugten Ausführungsbeispiel ist Kunststoff-Schaumelement 5b im Wesentlichen hülsenartig ausgestaltet und über eine insbesondere dornartige Aufnahme 13 geschoben. Für die Befestigung besonders vorteilhaft ist es, wenn das Kunststoff-Schaumelement 5b unter Vorspannung, das KunststoffSchaumelement 5b elastisch aufweitend, auf die Aufnahme 13 geschoben ist.Particularly cost-effective and at the same time robust is a variant in which the plastic foam element 5 is fastened by its inherent elasticity to the closing system component 1a, moreover. At the in Fig. 2 illustrated preferred embodiment, plastic foam element 5b is designed substantially sleeve-like and a particular thorn-like Shot 13 pushed. It is particularly advantageous for the attachment when the plastic foam element 5b is pushed onto the receptacle 13 under prestress, the plastic foam element 5b elastically widening.

Auch für die Herstellung des Kunststoff-Schaumelements 5 sind verschiedene Varianten möglich. In einer Variante ist das Kunststoff-Schaumelement 5 extrudiert. In diesem Fall wird das Kunststoff-Schaumelement 5 vorzugsweise aus einem extrudierten Halbzeug ausgestanzt sein. Auf das Stanzen kann verzichtet werden, wenn das Kunststoff-Schaumelement 5 im Kunststoff-Spritzgießverfahren spritzgegossen ist.Also for the production of the plastic foam element 5 different variants are possible. In a variant, the plastic foam element 5 is extruded. In this case, the plastic foam element 5 will preferably be punched out of an extruded semi-finished product. The punching can be dispensed with if the plastic foam element 5 is injection molded in the plastic injection molding process.

Nach einer weiteren Lehre, der eigenständige Bedeutung zukommt, wird ein Schließsystem 1 mit einem vorschlagsgemäßen Kraftfahrzeugschloss 1a und/oder mit einer vorschlagsgemäßen Schließhilfsanordnung beansprucht. Auf alle Ausführungen zu Kraftfahrzeugschloss 1a und Schließhilfsanordnung darf verwiesen werden.According to another teaching, which has independent significance, a locking system 1 is claimed with a proposed motor vehicle lock 1a and / or with a proposed auxiliary closing arrangement. Reference may be made to all versions of motor vehicle lock 1a and closing auxiliary arrangement.
