Description

Die vorliegende Erfindung betrifft ein Kraftfahrzeugschloss aufweisend ein Schlossgehäuse mit wenigstens einem Gesperre und Betätigungsmitteln. Die Erfindung findet insbesondere Anwendung im Bereich der Schließsysteme für Kraftfaluzeugtüren.The present invention relates to a motor vehicle lock comprising a lock housing with at least one locking mechanism and actuating means. The invention finds particular application in the field of locking systems for Kraftfaluzeugtüren.

Ein solches Kraftfahrzeugschloss dient beispielsweise zum Verschließen bzw. Öffnen von Kraftfahrzeugtüren, -klappen und dergleichen. Da das Kraftfahrzeugschloss bzw. die darin enthaltenen Komponenten regelmäßig staub und/oder wassergeschützt angeordnet sind, wird regelmäßig ein geschlossenes Schlossgehäuse bereitgestellt, in dem insbesondere auch das Gesperre vorgesehen ist. Das Gesperre setzt sich üblicherweise aus einer Drehfalle und zumindest einer Sperrklinke zusammen, wobei diese Gesperrebauteile so angeordnet sind, dass sie einen karosserieseitig befestigten Schlosshalter in der verriegelten Position aufnehmen und arretieren können. Die Sperrklinke hat dabei die Aufgabe, die Drehfalle in dieser Position zu blockieren.Such a motor vehicle lock is used for example for closing or opening of motor vehicle doors, flaps and the like. Since the motor vehicle lock or the components contained therein are regularly arranged dust and / or water protected, a closed lock housing is regularly provided, in which in particular the locking mechanism is provided. The ratchet is usually composed of a catch and at least one pawl, said ratchet members are arranged so that they can receive and lock a body-mounted lock holder in the locked position. The pawl has the task of blocking the catch in this position.

In diesem Zusammenhang ist zu berücksichtigen, dass ein solches Gesperre insbesondere bei einem Kfz-Seitenaufprall erhöhten Kräften ausgesetzt ist, beispielsweise dann, wenn ein Türaußenblech gegen das Gehäuse gedrückt wird und hier eine massive Verformung verursacht. Das kann im Extremfall zu einer Blockade des Gesperres führen, so dass eine zugehörige Kraftfahrzeugtür nur noch mit sehr hohem Aufwand zu öffnen ist. Deshalb wurde bereits vorgeschlagen, zur Verbesserung der Crash-Sicherheit Verstärkungselemente im Kraftfahrzeugschloss vorzusehen, z. B. in der Gestalt von Verstärkungsplatten, die mit dem Gehäuse verbunden sind.In this context, it should be noted that such a locking is exposed to increased forces, especially in a car side impact, for example, when a door outer panel is pressed against the housing and here causes a massive deformation. In the extreme case, this can lead to a blockage of the locking mechanism, so that an associated motor vehicle door can only be opened with great effort. Therefore, it has been proposed to provide reinforcing elements in the motor vehicle lock to improve the crash safety, z. In the form of reinforcing plates connected to the housing.

Die bekannten Kraftfahrzeugschlösser haben sich in dieser Hinsicht bereits weit entwickelt, allerdings können immer noch Crash-Szenarien zu einer unerwünschten Einschränkung der Betriebssicherheit führen, insbesondere auch dann, wenn die Hauptverformung in einem vom Kraftfahrzeug benachbart angeordneten Bereich stattfindet.The known motor vehicle locks have already developed far in this regard, but still crash scenarios can lead to an undesirable restriction of operational safety, especially when the main deformation takes place in an area arranged adjacent to the motor vehicle.

Aus der DE 10 2005 012 419 A1 geht ein Lagerbügel für eine Fahrzeugfür hervor.From the DE 10 2005 012 419 A1 goes out a bearing bracket for a vehicle for.

Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, die mit Bezug auf den Stand der Technik geschilderten Probleme zumindest teilweise zu lösen. Darüber hinaus soll insbesondere ein Kraftfahrzeugschloss angegeben werden, das im Hinblick auf die Betriebssicherheit während eines Seiten-Crashs oder erhöhten mechanische Beanspruchungen gleichwohl die Betriebssicherheit gewährleistet. Zudem soll das Kraftfahrzeugschloss kostengünstig herstellbar sein und einen geringeren Montageaufwand erfordern.On this basis, it is an object of the present invention, at least partially solve the problems described with reference to the prior art. In addition, in particular, a motor vehicle lock should be specified, which nevertheless ensures operational safety with regard to operational safety during a side crash or increased mechanical stresses. In addition, the motor vehicle lock should be inexpensive to produce and require less installation effort.

Diese Aufgaben werden gelöst mit einem Kraftfahrzeugschloss gemäß den Merkmalen des Patentanspruchs 1. Weitere vorteilhafte Ausgestaltungen des Kraftfahrzeugschlosses sind in den abhängig formulierten Patentansprüchen angegeben. Es ist darauf hinzuweisen, dass die in den Patentansprüchen einzeln aufgeführten Merkmale in beliebiger, technologisch sinnvoller, Weise miteinander kombiniert werden können und weitere Ausgestaltungen der Erfindung aufzeigen. Die Beschreibung, insbesondere im Zusammenhang mit den Figuren, charakterisiert und spezifiziert die Erfindung zusätzlich.These objects are achieved with a motor vehicle lock according to the features of claim 1. Further advantageous embodiments of the motor vehicle lock are specified in the dependent formulated claims. It should be noted that the features listed individually in the claims in any technologically meaningful way, can be combined with each other and show other embodiments of the invention. The description, in particular in connection with the figures, additionally characterizes and specifies the invention.

Das erfindungsgemäße Kraftfahrzeugschloss weist ein Schlossgehäuse mit wenigstens einem Gesperre und Betätigungsmitteln auf, wobei sich zumindest ein Betätigungsmittel durch eine Öffnung im Schlossgehäuse hindurch erstreckt und diese Öffnung mit zumindest einem Verstärkungseinsatz ausgebildet istThe motor vehicle lock according to the invention has a lock housing with at least one locking mechanism and actuating means, wherein at least one actuating means extends through an opening in the lock housing and this opening is formed with at least one reinforcement insert

Wie bereits in der Einleitung erläutert, liegt im verriegelten Zustand die Situation vor, dass die Drehfalle mittels einer Sperrklinke bewegungsblockiert den Schlosshalter aufnimmt. Um nun das Gesperre zu entriegeln, müssen Betätigungsmittel am Gesperre angreifen, die eine Trennung der Gesperrebauteile zum gewünschten Zeitpunkt gewährleisten. Diese Betätigungsmittel können beispielsweise Hebel, Bowdenzüge, Antriebsstränge und ähnliche Bewegungs- und/oder Kraft- und/oder Drehmomentübertrager sein. Der Benutzer wird diese Betätigung des Gesperres zumeist an einem Ort auslösen, der entfernt vom Kraftfahrzeugschloss angeordnet ist, beispielsweise ausgehend von einem Türaußengriff und/oder einem Türinnengriff. Das heißt mit anderen Worten, dass sich die Betätigungsmittel, die letztendlich eine Wirkverbindung zwischen Gesperre und beispielsweise dem Türgriff bereitstellen, auch durch das Schlossgehäuse hindurch erstrecken bzw. dort fixiert und/oder angebunden sind. Dabei ist möglich, dass mit dem Schlossgehäuse direkt eine Öffnung hin zum Innenraum des Schlossgehäuses bereitgestellt wird, es ist jedoch auch möglich, dass eine Öffnung zur Aufnahme der Betätigungsmittel außen und/oder innen am Schlossgehäuse bereitgestellt ist. Die Öffnung kann somit insbesondere nach Art einer Ausnehmung, Durchlass, Luke, Loch, etc. ausgeführt sein, wobei diese in die Umgebung des Schlossgehäuses sich erstreckend und/oder die Umgebung mit dem Innenraum verbindend ausgebildet sein kann. Jedenfalls dienen diese Öffnungen zur örtlichen Fixierung der Betätigungsmittel mit Bezug auf das Schlossgehäuse bzw. die darin angeordneten Gesperrebauteile. Somit bildet die Öffnung insbesondere den Anlenkpunkt für das äußere Betätigungsmittel - wie z.B. der Innenbetätigungshebel und/oder der Außenbetätigungshebel.As already explained in the introduction, is in the locked state, the situation that the catch by means of a pawl motion blocking the lock holder receives. In order to unlock the locking mechanism, actuating means must engage the locking mechanism, which ensure a separation of the locking components at the desired time. These actuating means may be, for example, levers, Bowden cables, drive trains and similar motion and / or force and / or torque converter. The user will usually trigger this actuation of the locking mechanism in a location which is arranged away from the motor vehicle lock, for example, starting from an outside door handle and / or an inside door handle. In other words, the actuating means, which ultimately provide an operative connection between the locking mechanism and, for example, the door handle, also extend through the lock housing or are fixed and / or connected there. It is possible that with the lock housing an opening is provided directly to the interior of the lock housing, but it is also possible that an opening for receiving the actuating means is provided on the outside and / or inside of the lock housing. The opening can thus be designed, in particular, in the manner of a recess, passage, hatch, hole, etc., whereby this can extend into the surroundings of the lock housing and / or the surroundings can be designed to connect with the interior. In any case, these openings are used for local fixation of the actuating means with respect to the lock housing or the Gesperrebauteile disposed therein. Thus, the opening in particular forms the point of articulation for the outer actuating means - such as the internal operating lever and / or the external operating lever.

Hier wird nun weiter vorgeschlagen, dass diese Öffnungen mit zumindest einem Verstärkungseinsatz ausgebildet sind. Auch wenn generell z.B. auch zwei Verstärkungseinsätze zur (teilweisen) Begrenzung der Öffnung vorgesehen sein können, so ist doch im Hinblick auf die kostengünstige Herstellung und den möglichst geringen Montageaufwand ein einzelner Verstärkungseinsatz pro Öffnung bevorzugt. Der Verstärkungseinsatz bildet insbesondere einen Teil oder (bevorzugt) den vollständigen Umfang der Öffnung. Dabei muss nicht die gesamte Öffnungsinnenfläche damit ausgebildet sein, es reicht vielmehr auch, wenn der Verstärkungseinsatz an bzw. in wenigstens einem Seitenbereich bzw. einer Stirnfläche der Öffnung vorgesehen ist. Der Verstärkungseinsatz könnte zwar auch nach Art einer Beschichtung ausgeführt sein, bevorzugt ist jedoch eine ring- bzw. kragenförmige Ausgestaltung des Verstärkungseinsatzes im Bereich der Öffnung. Der Verstärkungseinsatz zeichnet sich insbesondere dadurch aus, dass er erhöhte Festigkeitseigenschaften gegenüber der die Öffnung bildende Struktur des Schlossgehäuses aufweist. Damit wird insbesondere ein Verschleißschutz bzw. Ausbruchsschutz für den Fall einer besonders hohen Beanspruchung, wie z. B. im Fall eines Seitenaufpralls, bereitgestellt.Here it is now further proposed that these openings are formed with at least one reinforcing insert. Although in general, for example, two reinforcing inserts for (partial) limitation of the opening can be provided, so it is still preferable in view of the cost-effective production and the lowest possible assembly costs, a single reinforcing insert per opening. The reinforcing insert in particular forms a part or (preferably) the complete circumference of the opening. It does not have the entire opening inner surface be formed so that it is sufficient even if the reinforcing insert is provided on or in at least one side region or an end face of the opening. Although the reinforcing insert could also be designed in the manner of a coating, preference is given to a ring-shaped or collar-shaped configuration of the reinforcing insert in the region of the opening. The reinforcing insert is characterized in particular by the fact that it has increased strength properties with respect to the opening-forming structure of the lock housing. This is especially a wear protection or escape protection for the case of a particularly high stress, such. In the case of a side impact.

Gemäß einer weiteren Ausführungsvariante des Kraftfahrzeugschlosses wird auch vorgeschlagen, dass der zumindest eine Verstärkungseinsatz ein anderes Material als das die Öffnung bildende Schlossgehäuse aufweist. So wird hier beispielsweise in Betracht gezogen, das Schlossgehäuse im Bereich der Öffnung mit Kunststoff auszuführen und den zumindest einen Verstärkungseinsatz aus Metall bereitzustellen. Damit hat der Verstärkungseinsatz insbesondere eine höhere Abriebfestigkeit und Verformungssteifigkeit.According to a further embodiment variant of the motor vehicle lock, it is also proposed that the at least one reinforcing insert has a different material than the lock housing forming the opening. For example, it is considered here to make the lock housing in the region of the opening with plastic and to provide the at least one reinforcing insert made of metal. Thus, the reinforcing insert in particular has a higher abrasion resistance and deformation stiffness.

Darüber hinaus wird als vorteilhaft erachtet, wenn der zumindest eine Verstärkungseinsatz die Öffnung umschließt und sich in einen Innenraum des Schlossgehäuses hinein erstreckt. Somit wird der Verstärkungseinsatz beispielsweise nach Art einer (ggf. offenen) Ringscheibe ausgebildet, die außen an der Öffnung (teilweise) den Rand bildet, wobei der Verstärlcungseinsatz dann eine Lasche bildet, der sich über die Öffnung hinaus nach innen erstreckt. Damit ist insbesondere gemeint, dass sich der Verstärkungseinsatz bis hinein in einen Innenraum des Schlossgehäuses hinein erstreckt, um beispielsweise dort befestigt zu sein und/oder dort weitere Funktionen zu übernehmen.In addition, it is considered advantageous if the at least one reinforcing insert surrounds the opening and extends into an interior of the lock housing. Thus, the reinforcing insert is formed, for example, in the manner of a (possibly open) annular disc which forms the rim (partially) on the outside of the opening, the reinforcing insert then forming a tab which extends inwardly beyond the opening. This means, in particular, that the reinforcing insert extends into an interior space of the lock housing so as to be fastened there, for example, and / or to assume additional functions there.

Einer Weiterbildung des Kraftfahrzeugschlosses zufolge bildet der zumindest eine Verstärkungseinsatz eine Rastverbindung mit dem Schlossgehäuse im Bereich der Öffnung. Dabei wird eine einfache Montage von Verstärkungseinsatz und Schlossgehäuse realisiert. Zu diesem Zweck kann, beispielsweise der leichter verformbare Teil des Kunststoff-Schlossgehäuses formschlüssig mit dem Verstärkungseinsatz in Kontakt gebracht werden. Dabei können beispielsweise leichte Hinterschneidungen gebildet sein, so dass eine Klick- bzw. Rastverbindung (die gegebenenfalls auch wieder lösbar ist) schnell und einfach realisiert ist.According to a development of the motor vehicle lock, the at least one reinforcement insert forms a latching connection with the lock housing in the region of the opening. In this case, a simple installation of reinforcing insert and lock housing is realized. For this purpose, for example, the more easily deformable part of the plastic lock housing can be brought into positive contact with the reinforcing insert in contact. In this case, for example, slight undercuts may be formed, so that a click or locking connection (which may also be releasable again) is realized quickly and easily.

Außerdem ist es im Hinblick auf die multifunktionale Ausgestaltung eines solchen Verstärkungseinsatzes vorteilhaft, wenn der zumindest eine Verstärkungseinsatz wenigstens eine Führung oder eine Lagerung für das zumindest eine Betätigungsmittel bildet. Ganz besonders bevorzugt ist der Verstärkungseinsatz mit Lagerungen und einer Führung für jedes Betätigungsmittel ausgeführt. So können beispielsweise zwei Fixpunkte für die Lagerung eines Bowdenzugs und/oder eines Hebels realisiert sein, wobei die Erstreckung des Bewegungsmittels zwischen diesen beiden Lagerpunkten gegebenenfalls geführt wird. Damit wird eine besonders belastbare und genaue Führung der Betriebsmittel im Schlossgehäuse mittels des Verstärkungseinsatzes realisiert, wobei die Funlctionssicherheit gleichzeitig auch Crash-Fall verbessert wird. Nur der Vollständigkeit halber sei darauf hingewiesen, dass selbstverständlich die Lagerung und/oder Führung mit weiteren, gegebenenfalls separaten, Bauteilen ausgeführt sein können, insbesondere mit Buchsen, Dichtungen und ähnlichem.Moreover, in view of the multifunctional design of such a reinforcing insert, it is advantageous if the at least one reinforcing insert forms at least one guide or a bearing for the at least one actuating means. Most preferably, the reinforcing insert is designed with bearings and a guide for each actuator. For example, two fixed points for the storage of a Bowden cable and / or a lever can be realized, wherein the extension of the movement means between these two bearing points is optionally performed. Thus, a particularly reliable and accurate guidance of the resources in the lock housing is realized by means of the reinforcing insert, wherein the Funluidssicherheit is also improved crash case. For the sake of completeness it should be pointed out that, of course, the bearing and / or guide can be designed with further, optionally separate, components, in particular with bushes, seals and the like.

Im Rahmen einer Weitebildung des Kraftfahrzeugschlosses ist der zumindest eine Verstärkungseinsatz mit einer Verstärkungsplatte gebildet, die sich zwischen dem Schlossgehäuse und dem Gesperre erstreckt. In diesem Fall wurde nicht nur die Betriebssicherheit der Betätigungsmittel im Bereich der Aufnahme beim Kraftfahrzeugschloss verbessert, sondern gleichzeitig eine Integration dieses Verstärkungseinsatzes mit den eingangs erwähnten Verstärkungsplatten realisiert. So kann bei gleichzeitiger Erhöhung der Betriebssicherheit die Teileanzahl zur Herstellung eines solchen Crash-gesicherten Kraftfahrzeugschlosses beibehalten werden. Außerdem wird durch die zumeist relativ starre Integration der Verstärkungsplatte eine formsteife Ausrichtung des Verstärkungseinsatzes im Hinblick auf die Öffnung und damit ein praktisch nahezu unveränderlicher Anlenkungspunkt des Betätigungsmittels an das Schlossgehäuse realisiert, so dass auch nach eine Vielzahl von Betätigungen eine leichtgängige, schnelle und exakte Betätigung gewährleistet werden kann.In the context of a development of the motor vehicle lock, the at least one reinforcing insert is formed with a reinforcing plate which extends between the lock housing and the locking mechanism. In this case, not only was the operational safety of the actuating means in the area of the receptacle in the motor vehicle lock improved, but at the same time an integration of this reinforcing insert with the reinforcing plates mentioned above is realized. So can be maintained while increasing the reliability of the number of parts for the production of such a crash-secured motor vehicle lock. In addition, by the mostly relatively rigid integration of the reinforcing plate, a dimensionally stable alignment of the reinforcing insert with respect to the opening and thus a virtually almost invariable articulation point of the actuating means realized on the lock housing, so that even after a variety of operations ensures a smooth, fast and accurate operation can be.

Im Hinblick auf das hier bevorzugte Anwendungsgebiet der Erfindung wird auch ein Kraftfaluzeug vorgeschlagen, das wenigstens ein hier erfindungsgemäß beschriebenes Kraftfahrzeugschloss aufweist. Das Kraftfahrzeug betrifft insbesondere Personenkraftwagen bzw. Lastkraftwagen.With regard to the preferred field of application of the invention, a power tool is also proposed which has at least one motor vehicle lock described here according to the invention. The motor vehicle relates in particular to passenger cars or trucks.

Fig. 1 veranschaulicht schematisch ein Kraftfahrzeug 14 mit einer Tür 15, die mit einem Kraftfaluzeugschloss 1 ausgeführt ist. Wie bekannt, lässt sich ein solches Kraftfahrzeugschloss 1 beispielsweise über einen Türgriff 16 an der Tür 15 betätigen, wobei der Betätigungswunsch bzw. die Betätigungsaktion über Betätigungsmittel 16 an das Gesperre 3 weitergegeben wird. Die Betätigungsmittel 6 können grundsätzlich auch als Hebel ausgeführt sein, hier sind beispielhaft Bowdenzüge 7 veranschaulicht. Fig. 1 schematically illustrates a motor vehicle 14 with a door 15, which is designed with a force lock effector 1. As is known, such a motor vehicle lock 1 can be actuated, for example, via a door handle 16 on the door 15, wherein the actuation request or the actuation action is transmitted via actuating means 16 to the locking mechanism 3. The actuating means 6 can in principle be designed as a lever, here are exemplified Bowden cables 7 illustrated.

Die Bewegungsmittel 6 erstrecken sich nunmehr in einen Innenraum 19 des Schlossgehäuses 2 hinein. Dort ist das Gesperre 3 angeordnet, welches eine Drehfalle 4 und eine Sperrklinke 5 aufweist. In der hier veranschaulichten Position nimmt die Drehfalle 4 einen karosserieseitig befestigten Schlosshalter 17 auf und ist über die Sperrklinke 5 beweguügsblockiert. Es lässt sich erahnen, wie wichtig es ist, dass weder die Betätigungsmittel 6 noch das Gesperre 3 durch übermäßige Beanspruchung in der Funktion beeinträchtigt wird, nämlich für den Fall, wenn von außen verunfallte Personen durch die Tür 15 geborgen werden sollen.The movement means 6 now extend into an interior 19 of the lock housing 2. There, the locking mechanism 3 is arranged, which has a rotary latch 4 and a pawl 5. In the position illustrated here, the rotary latch 4 receives a body-side fastened lock holder 17 and is beweguügsblockiert on the pawl 5. It can be guessed how important it is that neither the actuating means 6 nor the locking mechanism 3 is impaired by excessive stress in the function, namely for the case when accidentally injured persons are to be recovered by the door 15.

Die Fig. 2 zeigt in einer perspektivischen Darstellung eine Ausführungsvariante eines Kraftfahrzeugschlosses 1, wobei hier das gekapselte Schlossgehäuse 2 erkennbar ist. Im unteren rechten Bereich des Kraftfahrzeugschloss 1 ist nunmehr eine Öffnung 8 vorgesehen, in der ein Bowdenzug 7 über eine Lagerung 13 geführt bzw. fixiert ist. Die Öffnung 8 ist dabei in einem Teil des Schlossgehäuses 2 eingelassen, das aus Kunststoff gefertigt ist. Die Lagerung 13 ist in die U- bzw. Omega-förmige Öffnung 8 eingesetzt, wobei ein dort bereitgestellter Verstärkungseinsatz 9 die Fixierung der Lagerung 13 auch bei hohen Kräften sicherstellt. Dabei ist der Verstärkungseinsatz 9 mit der Verstärkungsplatte 18 verbunden, die sich nicht nur außen auf dem Schlossgehäuse sondern auch noch in innere Bereiche des Kraftfahrzeugschlosses 9 hinein erstreckt.The Fig. 2 shows a perspective view of an embodiment of a motor vehicle lock 1, in which case the encapsulated lock housing 2 can be seen. In the lower right area of the motor vehicle lock 1, an opening 8 is now provided, in which a Bowden cable 7 is guided or fixed via a bearing 13. The opening 8 is embedded in a part of the lock housing 2, which is made of plastic. The bearing 13 is inserted into the U- or omega-shaped opening 8, wherein there provided a reinforcing insert 9 ensures the fixation of the bearing 13 even at high forces. In this case, the reinforcing insert 9 is connected to the reinforcing plate 18, the extends not only outside of the lock housing but also in inner areas of the motor vehicle lock 9 inside.

Die Fig. 3 zeigt erneut perspektivisch eine Ausführungsvariante der Fixierung eines Betätigungsmittels 6 mit dem Schlossgehäuse 2. Im vorne dargestellten Bereich ist erneut eine (nicht geschlossene) Öffnung 8 bzw. Aufnahme für das Betätigungsmittel 6 ausgebildet. Im normalen Betrieb wird das Bewegungsmittel 6 beispielsweise in deren Erstreckungsrichtung vor und zurück bewegt bzw. mit einer entsprechenden Kraft beaufschlagt. Dies kann nun dazu führen, dass gerade die Öffnung 8 besonders hohen Kräften ausgesetzt ist, entweder aufgrund einer hohen Dauerbelastung und/oder einer übermäßig hohen Kraft. Um hier nun eine dauerhafte und ortsgenaue Fixierung im Schlossgehäuses 2 zu gewährleisten, ist stirnseitig zu der Öffnung 8 nach außen hin ein Verstärkungseinsatz 9 vorgesehen, der im Wesentlichen eine gleiche Öffnung bzw. Aufnahme für das Betätigungsmittel 6 ausformt. Um nunmehr im Betrieb einen stabilen Verbund zwischen Schlossgehäuse 2 und Verstärkungseinsatz 9 zu realisieren, sind die beiden über eine Rastverbindung 11 miteinander arretiert.The Fig. 3 again shows in perspective a variant of the embodiment of the fixation of an actuating means 6 with the lock housing 2. In the area shown in the foreground, again, a (non-closed) opening 8 or receptacle for the actuating means 6 is formed. In normal operation, the moving means 6 is moved for example in the direction of extension back and forth or acted upon by a corresponding force. This can now lead to the fact that the opening 8 is subjected to particularly high forces, either due to a high continuous load and / or an excessively high force. In order to ensure a permanent and localized fixation in the lock housing 2, a reinforcing insert 9 is provided on the front side to the opening 8 to the outside, which forms a substantially identical opening or receptacle for the actuating means 6. In order to realize now in operation a stable bond between the lock housing 2 and reinforcing insert 9, the two are locked together via a snap-in connection 11.

Auch in diesem Fall ist der Verstärkungseinsatz 9 nicht allein im Bereich der Öffnung 8 vorgesehen, sondern dieser erstreckt sich hin bis zu weiteren Lagerungen 13 für das Betätigungsmittel 6. In dem Verbindungsbereich zwischen der Öffnung 8 und der Lagerung 13 ist in einer Oberfläche sogar eine Führung 12 für das Betätigungsmittel 6 vorgesehen. Diese, insbesondere mit Metall bereitgestellte, Verstärkungsplatte 18, die gleichzeitig den Verstärkungseinsatz 9 bildet, zeichnet sich also durch eine besonders hohe Robustheit und Verformungssteifigkeit aus, so dass die Funktionalität der Betätigungsmittel 6 für viele Fälle gewährleistet werden kann.Also in this case, the reinforcing insert 9 is not provided alone in the region of the opening 8, but this extends to further bearings 13 for the actuating means 6. In the connecting region between the opening 8 and the bearing 13 is in a surface even a guide 12 is provided for the actuating means 6. This, in particular provided with metal, reinforcing plate 18, which simultaneously forms the reinforcing insert 9, thus characterized by a particularly high robustness and deformation stiffness, so that the functionality of the actuating means 6 can be ensured in many cases.

In der Fig. 4 ist perspektivisch eine Ausführungsvariante für eine Verstärkungsplatte 18 dargestellt, wobei diese in einer laschenförmigen Erweiterung den hier Omega-förmig ausgeformten Verstärkungsemsatz 9 zur Anlage an der Öffnung 8 ausformt. Hierbei ist gleichzeitig zu erkennen, dass sich die Verstärkungsplatte 18 bis hin in innere Bereiche des Schlossgehäuses 2 hinein erstreckt, insbesondere auch über die Drehachsen 20 des Gesperres 3, um somit gleichzeitig das hier nicht dargestellte Gesperre 3 im Falle eines Seitenaufpralls zu schützen.In the Fig. 4 is shown in perspective a variant for a reinforcing plate 18, which in a tab-like extension here Omega-shaped reinforcement set 9 forms to rest against the opening 8. It can be seen at the same time that the reinforcing plate 18 extends into inner areas of the lock housing 2, in particular also on the axes of rotation 20 of the locking mechanism 3, thus simultaneously to protect the locking mechanism 3, not shown here in the event of a side impact.

Als Draufsicht zeigt die Fig. 5 eine weitere Ausführungsvariante für eine Aufnahme des Betätigungsmittels 6 mit einer Öffnung 8 und dem Verstärkungseinsatz 9. Auch in diesem Beispiel ist der Verstärkungseinsatz 9 mit einer Verstärkungsplatte 18 einstückig verbunden. Die Öffnung 8 bzw. der Verstärkungseinsatz 9 dient hier insbesondere zur Aufnahme einer Buchse 21, die zur Lagerung des hier nur angedeuteten Betätigungsmittels 6 dient. Die Buchse 21 kann sich dabei insbesondere beidseitig der Öffnung 8 erstrecken, wobei gegebenenfalls auch auf der gegenüberliegenden Stirnfläche ein zusätzlicher, gegebenenfalls separater, Verstärkungseinsatz 9 befinden kann, wie es hier gestrichelt angedeutet ist.As a top view shows the Fig. 5 a further embodiment for receiving the actuating means 6 with an opening 8 and the reinforcing insert 9. Also in this example, the reinforcing insert 9 is integrally connected to a reinforcing plate 18. The opening 8 and the reinforcing insert 9 is used here in particular for receiving a bushing 21, which serves to support the actuating means 6 only indicated here. The bushing 21 may extend in particular on both sides of the opening 8, wherein optionally also on the opposite end face an additional, possibly separate, reinforcing insert 9 may be located, as indicated by dashed lines.
