Description

Die Erfindung betrifft Offnungs- und / oder Schließmechanismus an Türen, Klappen oder dgl., für ein Kraftfahrzeug mit einem Schloss aufweisend ein Gehäuse, in welchem zumindest ein Sperrelement angeordnet ist, welches eine Sperrklinke und eine Drehfalle aufweist und einem als Schließbügel ausgebildetes Schließelement, welches mit dem Schloss in Schließstellung in Wirkverbindung steht, wobei die Drehfalle zwischen einer Freigabestellung und einer das Schließelement fangenden Sperrstellung verlagerbar ist, und die Drehfalle mindestens einen Drehfallenabschnitt mit mindestens einer Anschlagsfläche aufweist und die Sperrklinke mindestens einen Sperrklinkenabschnitt mit mindestens einer Anschlagsfläche aufweist, wobei sich in Sperrstellung die Anschlagsfläche des Drehfallenabschnitts und die Anschlagsfläche des Sperrklinkenabschnitts in einem Kontaktbereich berühren, und dass das Gehäuse bei einer Deformierung des Gehäuses zumindest teilweise von dem Sperrelement, insbesondere von einem Abschnitt der Drehfalle, kontaktiert wird, um die Tür am Öffnen zu hindern.The invention relates to opening and / or closing mechanism on doors, flaps or the like., For a motor vehicle with a lock having a housing in which at least one locking element is arranged, which has a pawl and a catch and a closing element designed as a closing element which is in operative engagement with the lock in the closed position, wherein the rotary latch between a release position and the locking element catching locking position is displaced, and the rotary latch has at least one rotary latch section with at least one stop surface and the pawl has at least one pawl portion with at least one stop surface, wherein in Locking position, the stop surface of the rotary latch portion and the abutment surface of the pawl portion in a contact area touch, and that the housing at a deformation of the housing at least partially by the blocking element, in particular From a portion of the catch, is contacted to prevent the door from opening.

Aus dem Stand der Technik sind Schlösser bekannt, die eine Drehfalle und eine Sperrklinke aufweisen. Bei hohen Belastungen Quer zur Öffnungsrichtung kommen die Drehfalle und die Sperrklinke außer Eingriff, so dass sich das Schloss bei einem Aufprall vorzeitig öffnen könnte.Locks are known from the prior art, which have a catch and a pawl. At high loads transverse to the opening direction of the catch and the pawl disengage, so that the lock could open prematurely in an impact.

In der deutschen Offenlegungsschrift DE1948907 ist ein Fahrzeugtürschloss beschrieben, welches eine Drehfalle und eine Sperrklinke aufweist. Die Drehfalle weist eine Rastnase auf die bei einer Deformierung des Gehäuses mit einer Seitenwand des Gehäuses einen Formschluss bildet, um ein Öffnen der Tür zu verhindern. Nachteilig bei dieser Lösung ist jedoch, dass die Drehfalle zusätzlich mit einer Rastnase versehen werden muss, die ausschließlich die Funktion aufweist, bei einer Deformierung des Gehäuses, beispielsweise bei einem Crash, mit der Ausnehmung am Gehäuse einen Formschluss zu bilden. Dies bedeutet einen höheren Fertigungsaufwand, welcher unnötiger Weise die Herstellungskosten erhöht.In the German Offenlegungsschrift DE1948907 a vehicle door lock is described, which has a rotary latch and a pawl. The rotary latch has a latching nose on which forms a positive connection with a deformation of the housing with a side wall of the housing to prevent opening of the door. A disadvantage of this solution, however, is that the catch additionally must be provided with a detent which has only the function to form a positive connection with a deformation of the housing, for example in a crash with the recess on the housing. This means a higher production cost, which unnecessarily increases the manufacturing cost.

Aus dem deutschen Gebrauchsmuster DE202005005689U1 , insbesondere aus dem in Figur 19 gezeigten Ausführungsbeispiel, ist ebenfalls ein Fahrzeugtürschloss bekannt, welches eine Drehfalle und eine Sperrklinke aufweist. In dieser Lösung weist die Drehfalle zwei Rastnasen auf, welche senkrecht in Richtung des Gehäuses ausgerichtet sind, um bei einem Crash mit den Ausnehmungen des Gehäuses einen Formschluss zu bilden. Hierbei wird jedoch nicht das Gehäuse deformiert, sondern die Drehfalle wird aufgrund einer Soll-Biegestelle B am Halteelement, welches die Drehfalle lagert, verkippt.
Diese Lösung weist den Nachteil auf, dass das Haltelement eine Soll Biegestelle auf weisen muss. Dies ist wiederum mit einem höheren Fertigungsaufwand verbunden, welcher die Konstruktionskosten erhöht.From the German utility model DE202005005689U1 , in particular from the in FIG. 19 In the embodiment shown, a vehicle door lock is also known, which has a rotary latch and a pawl. In this solution, the catch on two locking lugs, which are aligned perpendicularly in the direction of the housing to form a positive connection in a crash with the recesses of the housing. In this case, however, the housing is not deformed, but the rotary latch is tilted due to a desired bending point B on the holding element which supports the rotary latch.
This solution has the disadvantage that the holding element must have a desired bending point. This in turn is associated with a higher production cost, which increases the construction costs.

Zum Stand der Technik gehört auch die US6010164A , welche ein Fahrzeugtürschloss offenbart. Bei dieser Lösung weist das Gehäuse einen Vorsprung auf, der wiederum bei einer Deformation des Gehäuses mit einem an der Drehfalle angeordneten Vorsprung einen Formschluss bildet, um die Tür am Öffnen zu hindern. Allerdings ist auch bei diesem Fahrzeugschloss ein erhöhter konstruktiver Aufwand nötig, da die Drehfalle und das Gehäuse zusätzlich mit einem Vorsprung ausgebildet werden müssen.The state of the art also includes the US6010164A which discloses a vehicle door lock. In this solution, the housing has a projection, which in turn in a deformation of the housing with a on the Rotary latch arranged projection forms a positive connection to prevent the door from opening. However, an increased design effort is also necessary in this vehicle lock, since the catch and the housing must be additionally formed with a projection.

Aufgabe der Erfindung ist es daher eine Vorrichtung der eingangs genannten Art zu schaffen, welche auch bei einem Aufprall, insbesondere bei einem Crash sicherstellt, dass die Türen und Klappen des Fahrzeugs verschlossen bleiben und einfach sowie kostengünstig in der Herstellung ist.The object of the invention is therefore to provide a device of the type mentioned above, which ensures even in a crash, especially in a crash that the doors and flaps of the vehicle remain closed and is simple and inexpensive to manufacture.

Die Erfindung wird dadurch gelöst, dass bei einer Deformierung des Gehäuses in Sperrstellung mindestens eine Anschlagsfläche eines Drehfallenabschnitts der Drehfalle sich formschlüssig mit dem Gehäuse verbindet.The invention is achieved in that at a deformation of the housing in the blocking position at least one stop surface of a rotary latch portion of the rotary latch connects positively to the housing.

Die erfindungsgemäße Lösung bietet den Vorteil, dass im Gegenteil zum Stand der Technik die Anschlagsfläche des Drehfallenabschnitts der Drehfalle, welche in Sperrstellung die Anschlagsfläche des Sperrklinkenabschnitts der Sperrklinke in einem Kontaktbereich kontaktiert, gleichzeitig die Funktion aufweist, mit dem Gehäuse bei einer Deformierung des Gehäuses einen Formschluss zu bilden. Deshalb kann in vorteilhafterweise auf ein zusätzlich an der Drehfalle angeordnetes Bauteil, wie beispielsweise eine Rastnase, verzichtet werden. Die Anschlagsfläche des Drehfallenabschnitts der Drehfalle weist dementsprechend zwei Funktionen auf. Beim herkömmlichen Betrieb, d.h. im Sperrzustand dient sie dazu in Wirkverbindung mit der Anschlagsfläche des Sperrklinkenabschnitts der Sperrklinke, die Tür in einem verriegelten Zustand zu halten. Beim Crash sorgt Sie dafür, dass die Tür nicht geöffnet wird und die Insassen aus dem Fahrzeug heraus geschleudert werden, weil die Anschlagsfläche des Drehfallenabschnitts der Drehfalle mit dem Gehäuse einen Formschluss bildet. Der konstruktive Aufwand und die Herstellungskosten werden ohne Verzicht auf die Sicherheit demzufolge verringert.The solution according to the invention has the advantage that, in contrast to the prior art, the abutment surface of the rotary latch portion of the rotary latch, which contacts the abutment surface of the pawl portion of the pawl in a contact area in blocking position, at the same time has the function with the housing in a deformation of the housing a positive connection to build. Therefore, can be advantageously dispensed with an additionally arranged on the catch component, such as a latch. The abutment surface of the rotary latch portion of the rotary latch accordingly has two functions. In conventional operation, ie in the locked state, it serves in operative connection with the abutment surface of the pawl portion of the pawl to hold the door in a locked state. In the crash, it ensures that the door is not opened and the occupants are thrown out of the vehicle, because the stop surface of the rotary latch portion of the rotary latch forms a positive connection with the housing. The design effort and the manufacturing costs are consequently reduced without sacrificing safety.

Um die Sicherheit der Fahrzeuginsassen bei einem Crash weiter zu erhöhen, ist nach einer weiteren Ausgestaltung des Gegenstandes der Erfindung vorgesehen, dass die Drehfalle mindestens einen weiteren Drehfallenabschnitt mit einer zweiten Anschlagsfläche aufweist, der bei der Deformierung des Gehäuses sich formschlüssig mit dem Gehäuse verbindet.In order to further increase the safety of the vehicle occupants in the event of a crash, according to a further embodiment of the subject invention, the rotary latch has at least one further rotary latch section with a second abutment surface which, when the housing deforms, positively connects to the housing.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist dem Gehäuse mindestens ein Mittel zugeordnet ist, mit welchem sich mindestens eine Anschlagsfläche eines Drehfallenabschnitts formschlüssig verbindet.According to a further preferred embodiment of the invention, the housing is associated with at least one means with which at least one stop surface of a rotary latch section connects positively.

Nach einer weiteren Ausführungsform ist vorgesehen, dass das Mittel als Vertiefung im Gehäuse ausgebildet ist, mit welchem sich mindestens eine Anschlagsfläche eines Drehfallenabschnitts formschlüssig verbindet. Somit ist gewährleistet, dass bei einem Crash die formschlüssige Verbindung zwischen dem Gehäuse und der Anschlagsfläche des Drehfallenabschnitts der Drehfalle bestehen bleibt und ein Öffnen der Tür unmöglich ist. Die Vertiefung am Gehäuse ist einfach und kostengünstig herzustellen.According to a further embodiment it is provided that the means is formed as a recess in the housing, with which at least one stop surface of a rotary latch portion connects positively. This ensures that in a crash, the positive connection between the housing and the abutment surface of the rotary latch portion of the rotary latch remains and opening the door is impossible. The recess on the housing is simple and inexpensive to manufacture.

Nach einer alternativen Ausführungsform ist das Mittel als Vorsprung im Gehäuse ausgebildet, mit welchem sich mindestens eine Anschlagsfläche eines Drehfallenabschnitts formschlüssig verbindet.According to an alternative embodiment, the means is formed as a projection in the housing, with which at least one stop surface of a rotary latch section connects positively.

Nach einer weiteren alternativen Ausführungsform ist das Mittel als Ausnehmung im Gehäuse ausgebildet, mit welchem sich mindestens eine Anschlagsfläche eines Drehfallenabschnitts formschlüssig verbindet. Die Ausnehmung bietet den Vorteil, dass diese sehr einfach in ein bereits aus dem Stand der Technik bekanntes Gehäuses des Schlosses integriert werden kann. Dies wird vorzugsweise durch Bohren oder Stanzen durchgeführt.According to a further alternative embodiment, the means is formed as a recess in the housing, with which at least one stop surface of a rotary latch section connects positively. The recess has the advantage that it can be easily integrated into a housing of the lock already known from the prior art. This is preferably done by drilling or punching.

Vorzugsweise liegt die Ausnehmung in einer Ebene, welche parallel zu einer Ebene ist, in welcher die Seitenwände der Drehfalle liegen. Dadurch ist sichergestellt, dass die bei einem Crash hervorgerufenen Quer- bzw. Aufprallkräfte, die im Wesentlichen senkrecht zu den Seitenwänden der Drehfalle wirken, die Anschlagsfläche des Drehfallenabschnitts der Drehfalle in die Ausnehmung am Gehäuse führt, so dass sich ein Formschluss zwischen Anschlagsfläche und Ausnehmung bildet, der ein Öffnen der Tür verhindert.Preferably, the recess lies in a plane which is parallel to a plane in which the side walls of the rotary latch lie. This ensures that the impact forces generated in a crash, which act substantially perpendicular to the side walls of the rotary latch, the abutment surface of the rotary latch portion of the rotary latch leads into the recess on the housing, so that a positive connection between stop surface and recess forms, which opens the Door prevented.

Nach einer weiteren bevorzugten Ausführungsform ist das im Gehäuse angeordnete Mittel auf einer ersten Bahn angeordnet, welche beim Öffnungs-/Schließvorgang von mindestens einem Drehfallenabschnitt aufweisend mindestens eine Anschlagsfläche abgefahren wird.
Wenn sich das Mittel, wie beispielsweise die zuvor erwähnte Ausnehmung, auf der ersten Bahn angeordnet ist, so ist sichergestellt, dass die Anschlagsfläche des Drehfallenabschnitts der Drehfalle bei einer Deformierung des Gehäuses mit der Ausnehmung einen Formschluss bildet. Auf der Bahn können auch mehrer Mittel angeordnet sein, die in vorbestimmten Abständen zueinander angeordnet sind. So können beispielsweise mehrere Ausnehmungen auf einer Bahn angeordnet sein, die je nach Deformierung des Gehäuses und Stellung der Drehfalle für einen Formschluss mit mindestens einer Anschlagsfläche eines Drehfallenabschnitts zur Verfügung stehen können.According to a further preferred embodiment, the means arranged in the housing is arranged on a first path, which is traversed during the opening / closing operation of at least one rotary latch portion comprising at least one stop surface.
If the means, such as the recess mentioned above, is arranged on the first track, then it is ensured that the abutment surface of the rotary latch section of the rotary latch forms a positive connection in the case of a deformation of the housing with the recess. On the track also several means may be arranged, which are arranged at predetermined distances from each other. Thus, for example, a plurality of recesses may be arranged on a path which, depending on the deformation of the housing and the position of the rotary latch, can be available for positive engagement with at least one abutment surface of a rotary latch section.

Sehr sicher und einfach ist der konstruktive Aufbau des Schlosses, wenn das dem Gehäuse zugeordnete Mittel auf der ersten Bahn gegenüber dem Kontaktbereich angeordnet ist.Very safe and simple is the structural design of the castle when the housing associated with the means on the first path opposite the contact area is arranged.

Nach einer weiteren Ausgestaltung des Schlosses ist vorgesehen, dass das im Gehäuse angeordnete Mittel auf einer zweiten Bahn angeordnet ist, welche versetzt im Nahbereich zur ersten Bahn angeordnet ist, welche beim Öffnungs-/Schließvorgang von mindestens einem Drehfallenabschnitt aufweisend mindestens eine Anschlagsfläche abgefahren wird.According to a further embodiment of the lock, it is provided that the means arranged in the housing is arranged on a second path, which is offset in the vicinity of the first path, which is traversed by at least one rotary latch section comprising at least one stop surface during the opening / closing operation.

Vorzugsweise ist dann das dem Gehäuse zugeordnete Mittel auf der zweiten Bahn angeordnet ist, welche im Wesentlichen gegenüber dem Kontaktbereich angeordnet ist.Preferably, the means associated with the housing is then arranged on the second track, which is arranged substantially opposite the contact area.

Nach einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass das Mittel auf einer Rückseite eines Rückblechs des Gehäuses angeordnet ist.According to a further preferred embodiment it is provided that the means is arranged on a rear side of a rear plate of the housing.

Die Sicherheit des Schlosses gegen ein unbeabsichtigtes Öffnen der Tür bei einem Crash wird weiter erhöht, wenn mindestens eine Anschlagsfläche eines Drehfallenabschnitts als Vorsprung ausgebildet ist, welcher sich formschlüssig mit dem dem Gehäuse zugeordnetem Mittel verbindetThe safety of the lock against unintentional opening of the door in the event of a crash is further increased if at least one abutment surface of a rotary latch section is designed as a projection which connects in a form-fitting manner to the means associated with the housing

Vorzugsweise ist das Schloss unterhalb eines Türinnenbleches eines Fahrzeugs, insbesondere an einer Fahrzeugtür angeordnet ist.Preferably, the lock is located below a door inner panel of a vehicle, in particular on a vehicle door.

In den Figuren 1 bis 3 ist ein als Öffnungs- und Schließmechanismus ausgebildetes Heckklappenschloss 1 für eine nicht näher dargestellte Heckklappe eines Kraftfahrzeug abgebildet, welches unterhalb eines Türinnenblechs eines Fahrzeugs, insbesondere an einer Fahrzeugtür angeordnet ist.In the FIGS. 1 to 3 is designed as an opening and closing mechanism tailgate lock 1 for a tailgate of a motor vehicle, not shown, which is arranged below a door inner panel of a vehicle, in particular on a vehicle door.

Ein nicht näher gezeigtes und aus dem Stand der Technik bekanntes als Schließbügel ausgebildetes Schließelement, welches U-Förmig ausgebildet ist und mit dem Fahrzeug fest verbunden ist, steht bei einer Schließstellung mit dem Heckklappenschloss 1 in Wirkverbindung und verhindert somit ein Öffnen der Heckklappe.An unspecified and known from the prior art known as a closing bracket closing element, which is U-shaped and is firmly connected to the vehicle, is in a closed position with the Tailgate lock 1 in operative connection and thus prevents opening of the tailgate.

Das Heckklappenschloss 1 weist ein Gehäuse 2 auf. Innerhalb des Gehäuses sind Sperrelemente angeordnet, die als Drehfalle 3 und Sperrklinke 4 ausgebildet sind, wobei die Drehfalle 3 zwischen einer Freigabestellung und einer das Schließelement fangenden Sperrstellung verlagerbar ist.The tailgate lock 1 has a housing 2. Within the housing locking elements are arranged, which are designed as a rotary latch 3 and pawl 4, wherein the rotary latch 3 is displaceable between a release position and a locking element catching the locking position.

Bei der Sperrstellung wird zwischen zwei Zuständen unterschieden, und zwar zwischen einer Hauptrastsperrstellung und einer Vorrastsperrstellung. Bei der Hauptrastsperrstellung ist die Heckklappe fest verschlossen und bei der Vorrastsperrstellung befindet sich die Heckklappe in einem leicht verschlossenen Zustand, wobei zwischen Karosserierahmen und Tür ein Spalt ist.In the blocking position, a distinction is made between two states, namely between a main detent locking position and a Vorrastsperrstellung. In the main detent lock position, the tailgate is firmly closed and in the Vorrastsperrstellung the tailgate is in a slightly closed state, with a gap between the body frame and door.

Die Drehfalle 3 weist einen ersten Drehfallenabschnitt 5 mit einer als Hauptrast ausgebildeten ersten Anschlagsfläche 6 auf und die Sperrklinke 4 weist einen Sperrklinkenabschnitt 7 mit einer Anschlagsfläche 8 auf. Die Drehfalle 3 ist über einen Bolzen 9 und die Sperrklinke 4 ist über einen Bolzen 10, welcher jeweils an einer Rückseite 11 des Gehäuses 2 drehbar befestigt ist, jeweils drehbar über eine nicht näher gezeigte Feder gelagert.The rotary latch 3 has a first rotary latch section 5 with a first stop surface 6 designed as a main catch, and the pawl 4 has a pawl section 7 with a stop surface 8. The rotary latch 3 is connected via a pin 9 and the pawl 4 is rotatably supported via a respective bolt 10, which is rotatably mounted respectively on a rear side 11 of the housing 2 via a spring not shown in detail.

Die erste Anschlagsfläche 6 der Drehfalle 3 und die Anschlagsfläche 8 der Sperrklinke ist jeweils in Form eines Zahns ausgebildet, wobei sich in Sperrstellung des Heckklappenschlosses 1 die erste Anschlagsfläche 6 des ersten Drehfallenabschnitts 5 der Drehfalle 3 und die Anschlagsfläche 8 des Sperrklinkenabschnitts 7 der Sperrklinke 4 in einem Kontaktbereich 12 berühren. In diesem Fall befindet sich das Heckklappenschloss 1 mit dem Schließbügel in der Hauptrastsperrstellung (siehe Figur 2).The first stop surface 6 of the catch 3 and the abutment surface 8 of the pawl is each in the form of a tooth, wherein in the locked position of the tailgate lock 1, the first stop surface 6 of the first rotary latch portion 5 of the rotary latch 3 and the abutment surface 8 of the pawl portion 7 of the pawl 4 in touch a contact area 12. In this case, the tailgate lock 1 is located with the striker in the main detent lock position (see FIG. 2 ).

Ferner ist der Drehfalle 3 ein weiterer, zweiter Drehfallenabschnitt 13 mit einer zweiten Anschlagsfläche 14 zugeordnet. Bei der Vorrastsperrstellung kontaktiert die Anschlagsfläche 14 des zweiten Drehfallenabschnitts 13 die Anschlagsfläche 8 des Sperrklinkenabschnitts 7 der Sperrklinke 4, so dass ein Öffnen der Heckklappe verhindert wird. Dementsprechend dient die zweite Anschlagsfläche 14 des zweiten Drehfallenabschnitts 13 der Drehfalle 3 als Vorrast.Furthermore, the rotary latch 3 is assigned a further, second rotary latch section 13 with a second stop surface 14. In the Vorrastsperrstellung contacted the abutment surface 14 of the second rotary latch portion 13, the stop surface 8 of the pawl portion 7 of the pawl 4, so that opening of the tailgate is prevented. Accordingly, the second stop surface 14 of the second rotary latch portion 13 of the rotary latch 3 serves as a pre-detent.

Die Vorrast ist als Sicherheitsmittel vorgesehen, um bei einem Versagen der Hauptraststellung, insbesondere während der Fahrt, die Tür in Schließstellung zu halten. Ein Versagen der Hauptrastsperrstellung kann auftreten, wenn beispielsweise nach dem Schließvorgang die erste Anschlagsfläche 6 des ersten Drehfallenabschnitts 5 der Drehfalle 3 und die Anschlagsfläche 8 des Sperrklinkenabschnitts 7 der Sperrklinke 4 sich im Kontaktbereich 12 nur tangential berühren und eine kraftschlüssige Verbindung bilden, weil bereits geringe auf das Heckklappenschloss 1 wirkende Kräfte, welche beim Fahren eines Kraftfahrzeugs hervorgerufen werden, diese Verbindung lösen können. Im Falle eines Lösens dieser Verbindung dient die als Anschlagsfläche 14 des Drehfallenabschnitts 13 ausgebildete Vorrast als Sicherheitselement, das ein Öffnen der Heckklappe verhindert.The pre-restraint is provided as a safety means to keep the door in the closed position in the event of a failure of the main rest position, in particular while driving. A failure of the main detent lock position can occur, for example, after the closing operation, the first stop surface 6 of the first rotary latch portion 5 of the rotary latch 3 and the abutment surface 8 of the pawl portion 7 of the pawl 4 touch only tangentially in the contact area 12 and form a frictional connection, because already low on the tailgate lock 1 acting forces, which are caused when driving a motor vehicle, can solve this connection. In the case of a release of this compound designed as a stop surface 14 of the rotary latch portion 13 pre-catch serves as a security element that prevents opening of the tailgate.

Des Weiteren weist die Drehfalle 3 einen weiteren, dritten Drehfallenabschnitt 15 mit einer dritten Anschlagsfläche 16 auf. Auf der inneren Rückseite des Gehäuses 2 ist ein mit der Rückseite 11 fest verbundener Anschlag 17 angeordnet. In Sperrstellung - sowohl in Hauptrastsperrstellung als auch in Vorrastsperrstellung- befinden sich der Anschlag 17 und die dritte Anschlagsfläche 16 des dritten Drehfallenabschnitts 15 in einem kontaktfreien Zustand. Wenn das Hecklappenschloss 1 die Sperrstellung verlässt, dann dreht sich die Drehfalle 3 in Pfeilrichtung A zurück und die dritte Anschlagsfläche 16 des dritten Drehfallenabschnitts 15 der Drehfalle 3 schlägt an den Anschlag 17 an. Folglich sind der Schließbügel und die Drehfalle 3 außer Kontakt und ein Öffnen der als Tür ausgebildeten Heckklappe ist möglich. Der Anschlag 17 dient somit als Begrenzung für ein Durchdrehen der Drehfalle 3. Bei einem Crash, insbesondere bei einem Aufprall von hinten auf das Kraftfahrzeug, kann das Gehäuse 2 des Heckklappenschlosses aufgrund der Einwirkung von Querkräften deformiert werden. Im Falle der Deformation des Gehäuses wird mindestens eine Anschlagsfläche 6,14 eines Drehfallenabschnitts 5,13 der Drehfalle sich formschlüssig mit dem Gehäuse 2 verbinden. In dem vorliegenden Ausführungsbeispiel verbindet sich je nach Sperrstellung, entweder die erste Anschlagsfläche 6 (Hauptrast), wenn sich die Drehfalle 3 in Hauptrastsperrstellung befindet, oder die zweite Anschlagsfläche (Vorrast), wenn sich die Drehfalle 3 in Vorrastsperrstellung befindet, formschlüssig mit dem Gehäuse 2, insbesondere mit der Rückwand des Gehäuses 2.Furthermore, the rotary latch 3 has a further, third rotary latch section 15 with a third stop surface 16. On the inner rear side of the housing 2, a fixed to the back 11 stop 17 is arranged. In the blocking position - both in the main detent locking position and in Vorrastsperrstellung- are the stop 17 and the third stop surface 16 of the third rotary latch portion 15 in a non-contact state. When the tailgate latch 1 leaves the locking position, then the rotary latch 3 rotates back in the direction of arrow A and the third stop surface 16 of the third rotary latch section 15 of the rotary latch 3 abuts against the stop 17. Consequently, the striker and the rotary latch 3 are out of contact and opening of the door flap designed as a door is possible. The stop 17 thus serves as a limitation for a spin of the rotary latch 3. In a crash, especially in an impact from the rear of the vehicle, the housing 2 of the tailgate lock can be deformed due to the influence of shear forces. In the case of the deformation of the housing, at least one abutment surface 6, 14 of a rotary latch section 5, 13 of the rotary latch will positively connect to the housing 2. In the present embodiment, depending on the blocking position, either the first stop surface 6 (main branch) connects when the catch 3 is in the main detent position, or the second stop surface (pre-rest), when the catch 3 in Vorrastsperrstellung is, form-fitting with the housing 2, in particular with the rear wall of the housing. 2

Dem Gehäuse 2 des Heckklappenschlosses 1 ist ein Mittel 18 zugeordnet, mit welchem sich die jeweilige Anschlagsfläche 6,14 bei der Deformierung des Gehäuses 2 formschlüssig verbindet.The housing 2 of the tailgate lock 1 is associated with a means 18, with which the respective abutment surface 6.14 connects in a form-fitting manner during the deformation of the housing 2.

In dem vorliegenden Ausführungsbeispiel ist das Mittel 18 als Ausnehmung ausgebildet, mit welcher sich die erste Anschlagsfläche 6 des ersten Drehfallenabschnitts 5 oder die zweite Anschlagsfläche 14 des Drehfallenabschnitts 13 - abhängig von der Sperrstellung - formschlüssig verbindet, wobei die Ausnehmung gegenüber dem Kontaktbereich 12 auf einer ersten Bahn 19 angeordnet ist, welche beim Öffnungs-/Schließvorgang von dem ersten Drehfallenabschnitt 5 und dem zweiten Drehfallenabschnitt 13 abgefahren wird. In Figur 1 ist zu erkennen, dass die Ausnehmung in einer Ebene liegt, welche parallel zu der Ebene ist, in welcher Seitenwand der Drehfalle 3 liegt. Alternativ kann das Mittel 18 auch als Vertiefung ausgebildet sein. Ebenfalls ist es möglich, dass das Gehäuse 2 ein als Vorsprung ausgebildetes Mittel 18 aufweist, mit welchem bei einer Deformierung des Gehäuses 2 die erste Anschlagsfläche 6 des ersten Drehfallenabschnitts 5 oder die zweite Anschlagsfläche 14 des zweiten Drehfallenabschnitts 13 der Drehfalle 3 einen Formschluss bildet. Man kann auch die Drehfallenabschnitte 5,13,15 mit Vorsprüngen versehen, welche in Richtung der Rückseite 11 des Gehäuses 2 ausgerichtet sind und bei einer Deformierung des Gehäuses 2 mit dem Mittel 18 (Ausnehmung, Vertiefung, Vorsprung) einen Formschluss bilden, um die Tür, insbesondere die Heckklappe, bei einem Crash am Öffnen zu hindern.In the present embodiment, the means 18 is formed as a recess with which the first abutment surface 6 of the first rotary latch portion 5 or the second stop surface 14 of the rotary latch portion 13 - depending on the blocking position - positively connects, wherein the recess relative to the contact portion 12 on a first Track 19 is arranged, which is traveled in the opening / closing operation of the first rotary latch section 5 and the second rotary latch section 13. In FIG. 1 It can be seen that the recess lies in a plane which is parallel to the plane in which side wall of the rotary latch 3 lies. Alternatively, the means 18 may also be formed as a recess. It is also possible for the housing 2 to have a means 18 designed as a projection, with which the first abutment surface 6 of the first rotary latch section 5 or the second abutment surface 14 of the second rotary latch section 13 of the rotary latch 3 forms a positive connection in the event of deformation of the housing 2. It is also possible to provide the rotary latch sections 5, 13, 15 with projections which are aligned in the direction of the rear side 11 of the housing 2 and form a positive connection with the means 18 (recess, recess, projection) when the housing 2 is deformed , in particular the tailgate, in a crash to prevent the opening.

Die bei einem Crash auftretenden Querkräfte führen dazu, dass sich das Gehäuse 2 deformiert, und dadurch im Falle der Hauptrastsperrstellung der erste Drehfallenabschnitt 5 der Drehfalle 3 und der Sperrklinkenabschnitt 7 der Sperrklinke 4 sich in voneinander unterschiedliche Ebenen schieben, so dass die erste Anschlagsfläche 6 der Drehfalle 3 und die Anschlagsfläche 8 der Sperrklinke 4 im Kontaktbereich 12 außer Kontakt gelangen. Analog gilt dies für den Fall zweiten Drehfallenabschnitt 13 der Drehfalle 3, wenn die Vorrastsperrstellung vorliegt.The transverse forces occurring in a crash cause the housing 2 deformed, and thereby in the case of the main detent locking position of the first rotary latch portion 5 of the rotary latch 3 and the pawl portion 7 of the pawl 4 slide into different levels, so that the first stop surface 6 of Rotary latch 3 and the stop surface 8 of the pawl. 4 get out of contact in the contact area 12. This applies analogously to the case of the second rotary latch section 13 of the rotary latch 3 when the pre-barrier position is present.

Eine alternative Ausführungsform sieht vor, dass die Mittel auf einer zweiten Bahn 20 angeordnet sind, welche versetzt im Nahbereich zur ersten Bahn 19 angeordnet sind. Dann sind die Mittel 18 vorzugsweise im Wesentlichen gegenüber dem Kontaktbereich 12 angeordnet.An alternative embodiment provides that the means are arranged on a second web 20, which are arranged offset in the vicinity of the first web 19. Then, the means 18 are preferably arranged substantially opposite the contact region 12.

Ebenfalls ist es möglich, dass in der Nähe des Anschlags 17 ein Mittel 18 vorgesehen ist, welches mit der dritten Anschlagsfläche 16 des dritten Drehfallenabschnitts 15 der Drehfalle 3 bei einer Deformierung des Gehäuses 2 beim Crash einen Formschluss bildet.It is also possible that in the vicinity of the stop 17, a means 18 is provided which forms a positive connection with the third abutment surface 16 of the third rotary latch portion 15 of the rotary latch 3 in a deformation of the housing 2 in the crash.

Mann kann auch mehrere Mittel 18 bei dem Heckklappenschloss vorsehen, um die Sicherheit weiter zu erhöhen. So kann beispielsweise eine Ausnehmung auf der ersten Bahn 19 im Nahbereich des Anschlags 17 angeordnet sein und eine weitere Ausnehmung auf der zweiten Bahn 20 im Wesentlichen gegenüber dem Kontaktbereich 12 angeordnet sein.Man can also provide several means 18 at the tailgate lock to further increase safety. For example, a recess may be arranged on the first track 19 in the vicinity of the stop 17 and a further recess on the second track 20 may be arranged substantially opposite the contact zone 12.

In diesem Ausführungsbeispiel wird auf eine Heckklappe Bezug genommen. Die Erfindung ist nicht beschränkt auf Heckklappen und findet selbstverständlich auch Anwendung bei jeglichen anderen Formen von Türen, wie beispielsweise Seitentüren, Frontklappen und dergleichen.In this embodiment, reference is made to a tailgate. The invention is not limited to tailgates and of course also applies to any other forms of doors, such as side doors, front doors and the like.
