Description

Die Erfindung betrifft ein Schließsystem für eine Tür oder Klappe eines Kraftfahrzeug, mit einem Lagerbügel und einem an dem Lagerbügel angeordneten Zylinderschloss, wobei das Zylinderschloss eine Zylinderbuchse und einen Zylinderkern aufweist, und mit einer an dem Lagerbügel gehaltenen und die Zylinderbuchse hintergreifenden Verriegelungsklammer, die eine parallel zur Zylinderbuchse ausgerichtete Haltelasche aufweist, wobei eine Befestigungsschraube durch die Haltelasche hindurchgreift und mit einer Schraubenspitze in einer Aufnahmevertiefung der Zylinderbuchse einliegt, um die Verriegelungsklammer gegen die Zylinderbuchse vorzuspannen.The invention relates to a locking system for a door or hatch of a motor vehicle, with a bearing bracket and a cylinder lock arranged on the bearing bracket, the cylinder lock having a cylinder bush and a cylinder core, and with a locking clip held on the bearing bracket and engaging behind the cylinder bush, which has a parallel has a retaining lug aligned with the cylinder liner, with a fastening screw reaching through the retaining lug and having a screw tip resting in a receiving recess of the cylinder liner in order to prestress the locking clip against the cylinder liner.

Weiterhin betrifft die Erfindung eine Tür oder Klappe für ein Kraftfahrzeug mit einem solchen Schließsystem.Furthermore, the invention relates to a door or hatch for a motor vehicle with such a locking system.

Außerdem betrifft die Erfindung ein Kraftfahrzeug mit einer derartigen Tür oder Klappe.The invention also relates to a motor vehicle with such a door or flap.

Schließsysteme der eingangs genannten Art sind aus dem Stand der Technik bekannt. So offenbart die Offenlegungsschrift DE 10 2012 112 520 A1 ein gattungsgemäßes Schließsystem. Zum Verbessern des Diebstahlschutzes beziehungsweise Schutzes vor unbefugten Öffnen des Zylinderschlosses ist dort eine Verrieglungsklammer aus Stahlblech vorgesehen, welche an dem Lagerbügel gehalten ist und die Zylinderbuchse radial hintergreift. Um das Hintergreifen dauerhaft zu gewährleisten, ist die Verriegelungsklammer mithilfe einer Befestigungsschraube gegen die Zylinderbuchse vorgespannt. Dabei ist die Befestigungsschraube in eine Aufnahmevertiefung der Zylinderbuchse eingeführt, sodass die Zylinderbuchse an der Verriegelungsklammer verankert beziehungsweise verriegelt ist. Nur unter Aufwendung hoher Gewalt und/oder unter Zerstörung der Verriegelungsklammer kann die Zylinderbuchse nun aus dem Lagerbügel entfernt werden. Es hat sich gezeigt, dass ein derart ausgebildetes Schließsystem zu einer hohen Einbruchsicherheit oder Diebstahlsicherheit führt. Ähnliche Schließsysteme sind auch aus den Offenlegungsschriften DE 10 2004 012 456 A1 , DE 10 2008 019 013 A1 und EP 1 286 010 A1 bekannt.Locking systems of the type mentioned are known from the prior art. This is what the disclosure document reveals DE 10 2012 112 520 A1 a generic locking system. To improve the anti-theft protection or protection against unauthorized opening of the cylinder lock, a locking clip made of sheet steel is provided there, which is held on the bearing bracket and engages radially behind the cylinder bushing. In order to ensure permanent gripping from behind, the locking clip is preloaded against the cylinder liner with the aid of a fastening screw. The fastening screw is inserted into a receiving recess in the cylinder bushing, so that the cylinder bushing is anchored or locked on the locking clip. The cylinder liner can only be removed from the bearing bracket by using excessive force and/or by destroying the locking clip. It has been shown that a locking system designed in this way leads to high security against burglary or theft. Similar locking systems are also from the published documents DE 10 2004 012 456 A1 , DE 10 2008 019 013 A1 and EP 1 286 010 A1 known.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Schließsystem zu schaffen, das die Diebstahlsicherheit weiter erhöht.The invention is based on the object of creating an improved locking system which further increases the security against theft.

Die der Erfindung zugrundeliegende Aufgabe wird durch ein Schließsystem mit den Merkmalen des Anspruchs 1 gelöst. Dieses hat den Vorteil, dass ein Entfernen des Schließzylinders oder der Zylinderbuchse aus dem Lagerbügel nahezu unmöglich wird, ohne dass der Lagerbügel insgesamt zerstört wird. Durch die Erfindung wird erreicht, dass ein Herauslösen der Schraube aus der Aufnahmevertiefung, ohne die Befestigungsschraube selbst zu drehen, sicher verhindert ist. Erfindungsgemäß ist hierzu vorgesehen, dass auf einer Außenseite des Lagerbügels ein Schutzelement aufliegt, das zumindest eine Rückhaltelasche aufweist, die parallel zu der Zylinderbuchse ausgebildet ist, und dass die Befestigungsschraube auch durch die Rückhaltelasche geführt ist beziehungsweise die Rückhaltelasche durchgreift. Dadurch ist die Schraube durch die Rückhaltelasche des Schutzelements einerseits und durch die Haltelasche der Verriegelungsklammer andererseits an dem Lagerbügel geführt gehalten, sodass insbesondere ein Verbiegen der Schraube, bis sie mit ihrer Schraubenspitze aus der Ausnahmevertiefung herausgebogen ist, nicht mehr möglich ist. Dadurch ist die Diebstahlsicherheit weiter erhöht.The object on which the invention is based is achieved by a locking system having the features of claim 1 . This has the advantage that it is almost impossible to remove the lock cylinder or the cylinder bushing from the bearing bracket without destroying the bearing bracket as a whole. What is achieved by the invention is that the screw is reliably prevented from being released from the receiving recess without turning the fastening screw itself. According to the invention, a protective element rests on the outside of the bearing bracket and has at least one retaining tab that is formed parallel to the cylinder liner, and that the fastening screw is also guided through the retaining tab or reaches through the retaining tab. As a result, the screw is guided on the bearing bracket by the retaining tab of the protective element on the one hand and by the retaining tab of the locking clip on the other hand, so that in particular it is no longer possible to bend the screw until its screw tip has been bent out of the recessed recess. This further increases the security against theft.

Gemäß einer bevorzugten Weiterbildung der Erfindung sind die Verriegelungsklammer und das Schutzblech zumindest im Wesentlichen parallel zueinander an dem Lagerbügel angeordnet. Dadurch können Kräfte vorteilhaft von der Schraube in die Verriegelungsklammer und Schutzblech eingeleitet werden, wenn ein Diebstahlversuch vorgenommen wird.According to a preferred development of the invention, the locking clip and the protective plate are arranged at least essentially parallel to one another on the bearing bracket. This allows forces to be advantageously directed from the bolt into the latch bracket and fender if a theft attempt is made.

Insbesondere ist die Verriegelungsklammer axial zur Zylinderbuchse formschlüssig an dem Lagerbügel gehalten. Dadurch ist ein axiales Verschieben der Verriegelungsklammer in dem Lagerbügel sicher verhindert. Damit ist die Schraube durch die Rückhaltelasche und Haltelasche besonders fest in ihrer Ausrichtung an dem Lagerbügel beziehungsweise an der Zylinderbuchse befestigt.In particular, the locking clip is held in a form-fitting manner on the bearing bracket axially with respect to the cylinder bushing. As a result, axial displacement of the locking clip in the bearing bracket is reliably prevented. The screw is thus fastened particularly firmly in its alignment on the bearing bracket or on the cylinder bushing by the retaining tab and retaining tab.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist der Lagerbügel aus Kunststoff gefertigt, während die Verriegelungsklammer und das Schutzelement aus Metall gefertigt sind. Wird ein Diebstahlversucht vorgenommen, so schützen die metallischen Komponenten den Kunststoff des Lagerbügels vor Beschädigung, wodurch die Diebstahlsicherheit weiter erhöht wird.According to a preferred development of the invention, the bearing bracket is made of plastic, while the locking clip and the protective element are made of metal. If theft is attempted, the metallic components protect the plastic of the bearing bracket from damage, which further increases theft protection.

Vorzugsweise ist das Schutzelement als Schutzblech ausgebildet. Dies ist einfach und kostengünstig herstellbar und bietet die oben genannten Vorteile. Darüber hinaus hat das Schutzblech den Vorteil, dass es wenig Bauraum beansprucht und daher vorteilhaft in das Schließsystem integrierbar ist.The protective element is preferably designed as a protective plate. This can be produced easily and inexpensively and offers the advantages mentioned above. In addition, the mudguard has the advantage that it takes up little space and can therefore be advantageously integrated into the locking system.

Besonders bevorzugt weist die Haltelasche eine Schraubenöffnung mit einem Innengewinde auf, wobei die Befestigungsschraube in das Innengewinde eingeschraubt ist. Dadurch stützt sich die Befestigungsschraube einerseits an dem Schließzylinder und andererseits an der Haltelasche ab. Dadurch ist ein einfaches Verspannen der Verriegelungsklammer gegen die Zylinderbuchse mithilfe der Befestigungsschraube gewährleistet, weil die Befestigungsschraube die Haltelasche selbst an der Zylinderbuchse abstützt.The retaining tab particularly preferably has a screw opening with an internal thread, with the fastening screw being screwed into the internal thread. As a result, the fastening screw is supported on the lock cylinder on the one hand and on the retaining tab on the other hand. This ensures that the locking clip can be easily braced against the cylinder liner with the aid of the fastening screw, because the fastening screw itself supports the retaining tab on the cylinder liner.

Gemäß einer bevorzugten Weiterbildung der Erfindung sind die Schraubenspitze und die Aufnahmevertiefung der Zylinderbuchse korrespondierend zueinander ausgebildet. Dadurch wird der Vorteil erreicht, dass Schraubenspitze und Aufnahmevertiefung formschlüssig miteinander zusammenwirken, insbesondere zumindest im Wesentlichen spielfrei, sodass ein fester Sitz der Befestigungsschraube in der Aufnahmevertiefung gewährleistet ist. Vorzugsweise sind Schraubenspitze und Aufnahmevertiefung kegelförmig ausgebildet, um eine Selbstzentrierung der Befestigungsschraube bei der Montage zu ermöglichen.According to a preferred development of the invention, the screw tip and the receiving recess of the cylinder liner are designed to correspond to one another. This achieves the advantage that the screw tip and receiving recess interact with one another in a form-fitting manner, in particular at least essentially without play, so that a tight fit of the fastening screw in the receiving recess is ensured. Preferably, the screw tip and receiving recess are conical in shape in order to enable self-centering of the fastening screw during assembly.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist das Schutzelement ringförmig ausgebildet und umgibt das Zylinderschloss. Damit weist das Schutzelement grundsätzlich eine Form auf, die der der Verriegelungsklammer ähnelt. Dadurch, dass das Schutzelement den Schließzylinder ringförmig umgibt, gewährleistet es eine große Auflagefläche auf dem Lagerbügel, zur vorteilhaften Krafteinleitung, und schützt den Lagerbügel auch direkt vor Beschädigungen, weil es verhindert, dass ein Werkzeug im Bereich des Schließzylinders direkt auf den Lagerbügel trifft.According to a preferred development of the invention, the protective element is ring-shaped and surrounds the cylinder lock. Thus, the protective element basically has a shape that is similar to that of the locking clip. Because the protective element surrounds the lock cylinder in a ring, it ensures a large contact surface on the bearing bracket, for the advantageous introduction of force, and also protects the bearing bracket directly from damage because it prevents a tool in the area of the lock cylinder from hitting the bearing bracket directly.

Weiterhin ist bevorzugt vorgesehen, dass das Schutzelement als Außenverkleidung des Schließsystems, insbesondere der Tür oder Klappe, ausgebildet ist. Das Schutzelement weist somit einerseits die zuvor beschriebenen vorteilhaften Eigenschaften zum Diebstahlschutz auf, und bildet andererseits gleichzeitig ein Außenblech und somit ein Sichtteil des Schließsystems. Durch die hochintegrative Ausbildung ergeben sich Bauraumvorteile.Furthermore, it is preferably provided that the protective element is designed as an outer covering of the locking system, in particular of the door or flap. The protective element thus has on the one hand the advantageous properties for protection against theft described above, and on the other hand simultaneously forms an outer panel and thus a visible part of the locking system. The highly integrative design results in space advantages.

Gemäß einer bevorzugten Weiterbildung der Erfindung weist die Zylinderbuchse einen vom Lagerbügel vorstehenden Zylinderbuchsenkopf auf, der größer ist als eine Öffnung des ringförmigen Schutzelements, sodass sich der Zylinderbuchsenkopf axial direkt oder indirekt auf dem Schutzelement abstützt. Dadurch ist ein Eindrücken der Zylinderbuchse beziehungsweise des Schließzylinders in den Lagerbügel hinein beziehungsweise in Richtung der Innenseite der Tür oder der Klappe, sicher verhindert. Die Zylinderbuchse stützt sich mit ihrem vergrößerten Zylinderbuchsenkopf dabei an dem Schutzelement ab, das wiederum auf dem Lagerbügel aufliegt. Optional ist zwischen Schutzelement und Zylinderbuchsenkopf ein Verkleidungselement, insbesondere das Außenverkleidungselement, vorzugsweise Außenverkleidungsblech, angeordnet, sodass sich der Zylinderbuchsenkopf an dem Verkleidungselement abstützt, das sich wiederum an dem Schutzelement abstützt, das auf dem Lagerbügel aufliegt.According to a preferred development of the invention, the cylinder liner has a cylinder liner head that protrudes from the bearing bracket and is larger than an opening in the ring-shaped protective element, so that the cylinder liner head is axially supported directly or indirectly on the protective element. This reliably prevents the cylinder bushing or the lock cylinder from being pressed into the bearing bracket or in the direction of the inside of the door or the flap. The cylinder liner is supported with its enlarged cylinder liner head on the protective element, which in turn rests on the bearing bracket. Optionally, a cladding element, in particular the outer cladding element, is preferred between the protective element and the cylinder liner head Outer trim panel arranged so that the cylinder liner head bears on the trim member, which in turn bears on the protective member resting on the bearing bracket.

Die erfindungsgemäße Tür oder Klappe zeichnet sich durch das erfindungsgemäße Schließsystem aus. Es ergeben sich hierdurch die bereits genannten Vorteile.The door or flap according to the invention is characterized by the locking system according to the invention. This results in the advantages already mentioned.

Besonders bevorzugt weist die Tür oder Klappe ein Außenblech auf, das insbesondere das Schutzelement bildet und die Rückhaltelasche aufweist. Damit wird die Rückhaltelasche vorteilhaft durch das Außenblech der Tür oder Klappe selbst mitgebildet. Dadurch ergibt sich eine bauraumsparende Ausführung des Schließsystems.Particularly preferably, the door or flap has an outer panel, which in particular forms the protective element and has the retaining tab. The retaining tab is thus advantageously also formed by the outer panel of the door or flap itself. This results in a space-saving design of the locking system.

Das erfindungsgemäße Kraftfahrzeug mit den Merkmalen des Anspruchs 13 zeichnet sich durch die erfindungsgemäße Tür oder Klappe aus. Es ergeben sich hierdurch die bereits genannten Vorteile.The motor vehicle according to the invention with the features of claim 13 is characterized by the door or flap according to the invention. This results in the advantages already mentioned.

a second longitudinal sectional view through the bearing bracket in one to that in Figure 2A shown representation rotated by 90 ° plane.

Figuren 1A und 1B zeigen in unterschiedlichen Ansichten ein Schließsystem 1 für eine hier nicht dargestellte Tür oder Klappe eines Kraftfahrzeugs. Figur 1A zeigt dabei das Schließsystem 1 in einer Draufsicht und Figur 1B zeigt das Schließsystem 1 in einer Seitenansicht. Figures 1A and 1B show different views of a locking system 1 for a door or hatch of a motor vehicle, not shown here. Figure 1A shows the locking system 1 in a plan view and Figure 1B shows the locking system 1 in a side view.

Das Schließsystem 1 weist einen Lagebügel 2 auf, der aus Kunststoff gefertigt ist und an der Tür oder Klappe befestigbar ist. Der Lagerbügel ist dazu ausgebildet, einen betätigbaren Türgriff des Kraftfahrzeugs beweglich zu lagern, mittels dessen ein Benutzer die Klappe oder Tür entriegeln und öffnen kann. Aus Übersichtlichkeitsgründen ist der Türgriff nicht dargestellt.The locking system 1 has a bracket 2 that is made of plastic and can be attached to the door or hatch. The bearing bracket is designed to movably mount an actuatable door handle of the motor vehicle, by means of which a user can unlock and open the hatch or door. For reasons of clarity, the door handle is not shown.

Weiterhin trägt der Lagerbügel 2 ein Zylinderschloss 3. Dieses weist eine an dem Lagerbügel 2 befestigte Zylinderbuchse 4 auf, in welcher ein Zylinderkern 5 verdrehbar gelagert ist. Der Zylinderkern 5 weist eine Aufnahme für einen passenden Schlüssel auf, sodass eine Drehbewegung des Zylinderkerns 5 nur dann möglich ist, wenn der zugehörige Schlüssel in die Schlüsselaufnahme eingesteckt ist. Der Zylinderkern 5 ist mit einer Verriegelungsmechanik verbunden, mittels welcher die Klappe oder Tür an einem Fahrzeugrahmen arretierbar ist. Aus Übersichtlichkeitsgründen ist die Verriegelungsmechanik nicht gezeigt, dem Fachmann jedoch bekannt.Furthermore, the bearing bracket 2 carries a cylinder lock 3. This has a cylinder bushing 4 which is fastened to the bearing bracket 2 and in which a cylinder core 5 is rotatably mounted. The cylinder core 5 has a receptacle for a suitable key, so that the cylinder core 5 can only rotate when the associated key is inserted into the key receptacle. The cylinder core 5 is connected to a locking mechanism, by means of which the flap or door can be locked on a vehicle frame. For reasons of clarity, the locking mechanism is not shown, but is known to those skilled in the art.

Zur Arretierung der Zylinderbuchse 4 an dem Lagerbügel 2 ist eine Verriegelungsklammer 6 vorhanden, welche in einer Ebene senkrecht zur Längsmittelsachse der Zylinderbuchse 4 liegt und die Zylinderbuchse 4 radial hintergreift.To lock the cylinder liner 4 to the bearing bracket 2, a locking clip 6 is present, which lies in a plane perpendicular to the longitudinal center axis of the cylinder liner 4 and the cylinder liner 4 engages radially from behind.

Zur Veranschaulichung zeigen Figuren 2A und 2B jeweils Längsschnittdarstellungen durch den Lagerbügel 2 auf Höhe der Mittellängsachse der Zylinderbuchse 4. Dabei zeigt Figur 2A einen Längsschnitt durch das Schließsystem 1 gemäß der Linie A-A. Figur 2B zeigt eine Längsschnittdarstellung durch das Schließsystem 1 gemäß der Linie B-B aus Figur 1B. Die beiden Schnittebenen liegen somit in einem Winkel von 90° zueinander und führen jeweils durch die Längsmittelachse der Zylinderbuchse 4.Show for illustration Figures 2A and 2B each showing longitudinal sections through the bearing bracket 2 at the level of the central longitudinal axis of the cylinder liner 4 Figure 2A a longitudinal section through the locking system 1 along line AA. Figure 2B shows a longitudinal section through the locking system 1 along the line BB Figure 1B . The two sectional planes are thus at an angle of 90° to one another and each lead through the longitudinal center axis of the cylinder liner 4.

Wie aus Figuren 2A und 2B ersichtlich, umgreift die Verriegelungsklammer 6 die Zylinderbuchse 4 ringförmig. Dabei ist die Verriegelungsklammer 6 formschlüssig in axialer Richtung durch den Lagerbügel 2 gehalten, sodass sie insbesondere nur radial zu der Zylinderbuchse 4 verschiebbar ist. Der Lagerbügel 2 weist dazu eine Führungsaufnahme 7 auf, durch welche die Verriegelungsklammer 6 radial zur Zylinderbuchse 4 verschiebbar gelagert ist. Wie Figur 2B zeigt, weist die Zylinderbuchse 4 eine seitliche radiale Vertiefung 8 auf, in welche die Verriegelungsklammer 6 hineinziehbar ist, um die Zylinderbuchse 4 axial an dem Lagerbügel 2 zu befestigen. Um den Sitz der Verriegelungsklammer 6 in der Vertiefung 8 dauerhaft zu gewährleisten, ist der Verriegelungsklammer 6 eine Befestigungsschraube 9 zugeordnet.How out Figures 2A and 2B As can be seen, the locking clip 6 surrounds the cylinder liner 4 in a ring shape. In this case, the locking clip 6 is held in a form-fitting manner in the axial direction by the bearing bracket 2 , so that it can only be displaced radially with respect to the cylinder liner 4 . For this purpose, the bearing bracket 2 has a guide receptacle 7 through which the locking clip 6 is mounted so that it can be displaced radially with respect to the cylinder bushing 4 . How Figure 2B shows, the cylinder liner 4 has a lateral radial depression 8 into which the locking clip 6 can be drawn in order to fasten the cylinder liner 4 axially to the bearing bracket 2 . In order to permanently ensure that the locking clip 6 is seated in the depression 8 , the locking clip 6 is assigned a fastening screw 9 .

Die Verriegelungsklammer 6 weist eine Haltelasche 10 auf, die, wie beispielsweise in Figur 1B und 2B gezeigt, zumindest im Wesentlichen parallel zur Längsmittelachse der Zylinderbuchse 4 ausgerichtet ist und eine Schraubenöffnung 11 mit einem Innengewinde 12 aufweist. Die Befestigungsschraube ist in das Innengewinde 12 mit einer Schraubenspitze 13 in Richtung der Zylinderbuchse 4 zu vorderst eingeschraubt. Dadurch ist die Längsmittelachse der Befestigungsschraube 9 zumindest im Wesentlichen radial zu der Zylinderbuchse 4 ausgerichtet. Die Schraubenspitze 13 ist dazu ausgebildet, in eine Aufnahmevertiefung 14 der Zylinderbuchse 4 radial einzugreifen. Dazu sind die Schraubenspitze 13 und die Aufnahmevertiefung 14 korrespondierend zueinander ausgebildet. Gemäß dem vorliegenden Ausführungsbeispiel weisen die Schraubenspitze 13 und die Aufnahmevertiefung 14 einen zylinderförmigen Längsschnitt auf. Optional weisen die Schraubenspitze 13 und die Aufnahmevertiefung 14 einen kegelförmigen Längsschnitt auf, um ein Einfädeln der Befestigungsschraube 9 in die Aufnahmevertiefung 14 zu erleichtern und eine Selbstzentrierung zu ermöglichen.The locking clip 6 has a retaining tab 10 which, as for example in Figure 1B and 2 B shown, is aligned at least essentially parallel to the longitudinal central axis of the cylinder liner 4 and has a screw opening 11 with an internal thread 12 . The fastening screw is screwed into the internal thread 12 with a screw tip 13 in the direction of the cylinder liner 4 at the front. As a result, the longitudinal center axis of the fastening screw 9 is aligned at least essentially radially with respect to the cylinder liner 4 . The screw tip 13 is designed to engage radially in a receiving recess 14 of the cylinder liner 4 . These are the screw tip 13 and the Receiving recess 14 formed corresponding to each other. According to the present embodiment, the screw tip 13 and the receiving recess 14 have a cylindrical longitudinal section. Optionally, the screw tip 13 and the receiving recess 14 have a conical longitudinal section in order to facilitate threading of the fastening screw 9 into the receiving recess 14 and to enable self-centering.

Wird nun die Befestigungsschraube 9 in das Gewinde 12 eingeschraubt, sodass die Schraubenspitze 13 in der Aufnahmevertiefung 14 zum Liegen kommt, wie in Figur 2B gezeigt, so wird mit zunehmender Einschraubtiefe die Verriegelungsklammer 6 an ihrem von der Haltelasche 10 abgewandten Ende in die radiale Vertiefung 8 der Zylinderbuchse 4, die auf der der Aufnahmevertiefung 14 gegenüberliegenden beziehungsweise abgewandten Seite ausgebildet ist, hineingezogen, wodurch die Zylinderbuchse 4 fest an dem Lagerbügel 2 befestigt ist.If the fastening screw 9 is now screwed into the thread 12 so that the screw tip 13 comes to rest in the receiving recess 14, as in Figure 2B shown, as the screwing depth increases, the locking clip 6 is pulled at its end remote from the retaining tab 10 into the radial recess 8 of the cylinder bushing 4, which is formed on the side opposite or remote from the receiving recess 14, whereby the cylinder bushing 4 is firmly attached to the bearing bracket 2 is attached.

Das Schließsystem 1 weist darüber hinaus ein Schutzelement 15 auf. Das Schutzelement 15 ist als Schutzblech 16 ausgebildet, das auf einer Außenseite des Lagerbügels 2 aufliegt. Wie aus Figur 1A ersichtlich, ist das Schutzelement 15 ringförmig ausgebildet, sodass es, ähnlich wie die Verriegelungsklammer 6, die Zylinderbuchse 4 umgibt. Das Schutzelement 15 ist insbesondere parallel zur Verriegelungsklammer 6 angeordnet. Durch die ringförmige Ausbildung weist das Schutzelement 15 eine Öffnung 16 auf, durch welche die Zylinderbuchse 5 hindurchragt. Dabei ist die lichte Weite der Öffnung 16 kleiner als die Bereite eines Zylinderbuchsenkopfs 17 der Zylinderbuchse 4. Der Zylinderbuchsenkopf 17 der Zylinderbuchse 4 steht von dem Lagerbügel 2 vor, sodass das Schutzelement 15 unterhalb des Zylinderkopfs 17 liegt und zwischen Zylinderkopf 17 und Lagerbügel 2 verspannbar ist.The locking system 1 also has a protective element 15 . The protective element 15 is designed as a protective plate 16 which rests on an outside of the bearing bracket 2 . How out Figure 1A As can be seen, the protective element 15 is ring-shaped so that it surrounds the cylinder bushing 4 in a manner similar to the locking clip 6 . The protective element 15 is arranged in particular parallel to the locking clip 6 . Due to the ring-shaped design, the protective element 15 has an opening 16 through which the cylinder liner 5 protrudes. The clear width of the opening 16 is smaller than the width of a cylinder liner head 17 of the cylinder liner 4. The cylinder liner head 17 of the cylinder liner 4 protrudes from the bearing bracket 2, so that the protective element 15 lies below the cylinder head 17 and can be braced between the cylinder head 17 and the bearing bracket 2 .

Das Schutzelement 15 ist beispielsweise an dem Lagerbügel 2 verschraubt, um seine Position im Lagerbügel 2 festzulegen. Ist dies erfolgt, kann die Zylinderbuchse 4 nicht mehr nach innen in die Tür oder die Klappe eingedrückt werden, weil sich der Zylinderbuchsenkopf 17 an dem Schutzelement 15 abstützt.The protective element 15 is, for example, screwed to the bearing bracket 2 in order to fix its position in the bearing bracket 2 . Once this has taken place, the cylinder liner 4 can no longer be pressed inwards into the door or the hatch because the cylinder liner head 17 is supported on the protective element 15 .

Optional ist zwischen dem Schutzelement 15 und dem Zylinderkopf 17 außerdem eine Außenverkleidung 18 der Tür oder Klappe angeordnet, insbesondere in Form eines Verkleidungsblechs, das sich in dem Bereich des Zylinderkopfs 17 und Schutzelement 15 erstreckt.Optionally, an outer paneling 18 of the door or hatch is also arranged between the protective element 15 and the cylinder head 17 , in particular in the form of a panelling, which extends in the area of the cylinder head 17 and protective element 15 .

Das Schutzelement 15 ist so dazu ausgebildet, flächig auf dem Lagerbügel 2 aufzuliegen, um hohe Kräfte auf den Lagerbügel 2 übertragen zu können. Es verhindert, dass das Schließsystem 1 durch ein Eindrücken des Schließzylinders 3 aufgebrochen werden kann.The protective element 15 is designed to lie flat on the bearing bracket 2 in order to be able to transmit high forces to the bearing bracket 2 . It prevents the locking system 1 from being forced open by the locking cylinder 3 being pressed in.

Außerdem weist das Schutzblech 15 eine Rückhaltelasche 19 auf, die sich zumindest im Wesentlichen parallel zu dem Schließzylinder 3 erstreckt. Dabei ist die Rückhaltelasche 19 derart ausgebildet, dass sie eine Öffnung 20 aufweist, deren Innendurchmesser nur geringfügig größer als der Außendurchmesser der Befestigungsschraube 9 ist. Die Rückhaltelasche 19 erstreckt sich derart weit parallel zu dem Schließzylinder 3, dass die Öffnung 20 auf Höhe der Befestigungsschraube 9 liegt, wobei die Rückhaltelasche 19 dabei bevorzugt zwischen der Befestigungslasche 10 und der Zylinderbuchse 4 liegt. Die Befestigungsschraube 9 ist, wie insbesondere in Figur 2B ersichtlich, durch die Öffnung 20 hindurchgeführt, sodass die Schraube radial durch die Rückhaltelasche 19 umfangen und gestützt ist.In addition, the protective plate 15 has a retaining tab 19 which extends at least essentially parallel to the lock cylinder 3 . The retaining tab 19 is designed in such a way that it has an opening 20 whose inner diameter is only slightly larger than the outer diameter of the fastening screw 9 . The retaining tab 19 extends so far parallel to the lock cylinder 3 that the opening 20 is level with the fastening screw 9 , the retaining tab 19 preferably being located between the fastening tab 10 and the cylinder bushing 4 . The fastening screw 9 is, as in particular in Figure 2B as can be seen, passed through the opening 20 so that the screw is radially encompassed and supported by the retaining tab 19.

Wird nun bei einem Aufbrauchversuch eine hohe Kraft auf die Befestigungsschraube 9 ausgeübt, beispielsweise um diese aus der Aufnahmevertiefung 14 mit Gewalt zu entfernen, hindert das Schutzelement 15 mit der Rückhaltelasche 19 die Befestigungsschraube 9 daran, aus der Aufnahmevertiefung 14 herausgebogen zu werden. Dadurch ist ein Aufbrechen des Schließsystems 1 sicher verhindert.If a high force is now exerted on the fastening screw 9 in an attempt to use it up, for example in order to force it out of the receiving recess 14 , the protective element 15 with the retaining tab 19 prevents the fastening screw 9 from being bent out of the receiving recess 14 . This reliably prevents the locking system 1 from being forced open.

Insbesondere sind das Schutzelement 15 und die Verriegelungsklammer 6 aus Metall gefertigt, um hohen Kräften standzuhalten und den Lagerbügel 2 vor Schädigungen zu schützen.In particular, the protective element 15 and the locking clip 6 are made of metal in order to withstand high forces and to protect the bearing bracket 2 from damage.

Zur Sicherstellung der Dichtheit ist außerdem bevorzugt ein ringförmiges elastisch verformbares Dichtelement 21 zwischen Zylinderbuchsenkopf 17 und Außenverkleidungsteil 18 oder Schutzelement 15 vorgespannt gehalten.To ensure tightness, an annular, elastically deformable sealing element 21 is also preferably held prestressed between the cylinder liner head 17 and the outer lining part 18 or protective element 15 .
