Description

La présente invention concerne un verrou et plus particulièrement un verrou pour ouvrant de véhicule automobile et encore plus particulièrement un verrou de blocage de colonne de direction d'un véhicule automobile. Ce type de verrou comprend généralement un rotor imbriqué dans un stator, dans lequel le rotor est entraîné en rotation dans le stator lors de l'introduction de la clé adéquate pour déverrouiller un véhicule par exemple. Afin d'accroître la difficulté pour une personne mal intentionnée de forcer le verrou et donc éventuellement de voler le véhicule, un moyen anti-arrachement a été conçu au niveau du rotor afin d'empêcher son mouvement rotatoire lors de l'introduction d'un objet forçant le déverrouillage. Tels moyens sont connus par exemple des documents US1705344 , EP3150783 , JP 58-180348 ou US 2016/0039388 .The present invention relates to a lock and more particularly to a lock for an opening of a motor vehicle and even more particularly to a lock for locking the steering column of a motor vehicle. This type of lock generally comprises a rotor nested in a stator, in which the rotor is driven in rotation in the stator during the introduction of the appropriate key to unlock a vehicle for example. In order to increase the difficulty for an ill-intentioned person to force the lock and therefore possibly to steal the vehicle, an anti-tearing means has been designed at the level of the rotor in order to prevent its rotary movement during the introduction of a object forcing unlocking. Such means are known, for example from documents US1705344 , EP3150783 , JP 58-180348 or US 2016/0039388 .

Un moyen similaire tel que décrit ci-dessus est connu de l'art antérieur comme indiqué dans le brevet FR2964688 concernant un verrou de commutateur électrique rotatif pour antivol de véhicule automobile destiné à être inséré et fixé dans un corps de réception de véhicule automobile comprenant :

  • un stator à l'intérieur duquel un rotor est susceptible d'être mobile en rotation, lorsque la clé conforme au verrou est insérée de manière à dé-condamner le système de verrouillage du véhicule automobile, le stator comprenant un moyen de fixation au corps d'antivol, un cache du rotor fixé en face avant du stator, le cache présentant une ouverture pour le passage de la clé susceptible de coopérer avec le rotor, un moyen anti-arrachement porté par le cache et le stator pour fixer le cache au stator et retenir axialement le rotor dans le stator.
A similar means as described above is known from the prior art as indicated in the patent. FR2964688 concerning a rotary electrical switch lock for a motor vehicle anti-theft device intended to be inserted and fixed in a motor vehicle receiving body comprising:
  • a stator inside which a rotor is capable of being movable in rotation, when the key conforming to the lock is inserted so as to unlock the locking system of the motor vehicle, the stator comprising a means of attachment to the body of 'anti-theft device, a rotor cover fixed to the front face of the stator, the cover having an opening for the passage of the key capable of cooperating with the rotor, an anti-tearing means carried by the cover and the stator for fixing the cover to the stator and axially retaining the rotor in the stator.

Un inconvénient de ce moyen utilisé est qu'en introduisant un outil à travers le verrou, le mouvement de rotation du rotor est induit avec peu d'effort de la part d'un individu voulant forcer le verrou. Les moyens anti-arrachement actuels permettent d'éviter l'introduction d'objet afin de déverrouiller un ouvrant mais n'ont pas la fonction de bloquer le mouvement rotatoire du rotor efficacement.A disadvantage of this means used is that by introducing a tool through the lock, the rotational movement of the rotor is induced with little effort on the part of an individual wanting to force the lock. The current anti-tearing means make it possible to avoid the introduction of an object in order to unlock an opening but do not have the function of effectively blocking the rotary movement of the rotor.

Le dispositif selon l'invention vise à répondre à cet inconvénient en fournissant un verrou comprenant un rotor et un stator composé de deux éléments, ledit rotor comprenant au moins un moyen anti-arrachement disposé entre le conduit d'introduction de la clé et l'extrémité dudit rotor la plus proche dudit conduit d'introduction de la clé, caractérisé en ce que le moyen anti-arrachement comprend au moins une zone fusible apte à entraîner la division en au moins deux parties dudit moyen anti-arrachement, ledit moyen anti-arrachement comprenant également au moins une dent disposée radialement vers l'extérieur en direction du stator sur chaque extrémité de chacune desdites parties; ledit stator comprenant au moins un évidement sur chacun de ses éléments de manière à ce que chaque dent s'imbrique dans l'évidement correspondant lors d'une tentative d'effraction dudit verrou afin de bloquer le mouvement rotatoire dudit rotor.The device according to the invention aims to respond to this drawback by providing a lock comprising a rotor and a stator composed of two elements, said rotor comprising at least one anti-tearing means arranged between the conduit for introducing the key and the end of said rotor closest to said conduit for introducing the key, characterized in that the anti-tearing means comprises at least one fusible zone capable of causing the division into at least two parts of said anti-tearing means, said anti-tearing means breakout also comprising at least one tooth disposed radially outwards in the direction of the stator on each end of each of said parts; said stator comprising at least one recess on each of its elements so that each tooth fits into the corresponding recess during an attempt to break said lock in order to block the rotary movement of said rotor.

En effet, lors de l'introduction d'un objet pour forcer le mouvement rotatoire du rotor, chaque zone fusible cède permettant ainsi une division du moyen anti-arrachement en au moins deux parties et son déplacement radial jusqu'à la coopération de forme entre chaque dent du moyen anti-arrachement et chaque évidement correspondant dans le stator.Indeed, during the introduction of an object to force the rotary movement of the rotor, each fusible zone gives way thus allowing a division of the anti-tearing means into at least two parts and its radial displacement until the form cooperation between each tooth of the anti-pullout means and each corresponding recess in the stator.

Préférentiellement, chaque zone fusible présente un chanfrein. Cette surface fait que lorsque le verrou est forcé, la rupture de chaque zone fusible induit l'écartement des parties du moyen anti-arrachement par la poussée de l'objet introduit.Preferably, each fusible zone has a chamfer. This surface means that when the lock is forced, the breaking of each fusible zone induces the separation of the parts of the anti-tearing means by the thrust of the introduced object.

Encore préférentiellement, lors de la division du moyen anti-arrachement, chacune des parties dudit moyen anti-arrachement est apte à se déplacer radialement jusqu'à s'imbriquer dans les évidements du stator.Even more preferably, during the division of the anti-tearing means, each of the parts of said anti-tearing means is able to move radially until it is nested in the recesses of the stator.

Avantageusement, chaque partie du moyen anti-arrachement présente au moins deux congés disposés de part et d'autre de chaque dent de manière à ce que chaque congé forme butée avec le stator lors du déplacement radial de chaque partie dudit moyen anti-arrachement. Le moyen anti-arrachement est donc en butée contre le stator par l'intermédiaire de chaque congé de chaque partie du moyen anti-arrachement et le mouvement rotatoire du rotor est bloqué, évitant ainsi le déverrouillage d'un ouvrant par exemple.Advantageously, each part of the anti-tearing means has at least two fillets arranged on either side of each tooth so that each fillet forms a stop with the stator during the radial displacement of each part of said anti-tearing means. The anti-tearing means is therefore in abutment against the stator via each fillet of each part of the anti-tearing means and the Rotary movement of the rotor is blocked, thus preventing the unlocking of an opening for example.

Encore avantageusement, chacune des dents présente au moins chacune une rainure sur une des surfaces s'imbriquant dans les évidements, lesdits évidements présentant au moins chacun une languette sur une des surfaces recevant lesdites dents de façon à ce que chaque languette rentre dans chaque rainure de ladite dent.Again advantageously, each of the teeth has at least each one groove on one of the surfaces interlocking with the recesses, said recesses each having at least one tongue on one of the surfaces receiving said teeth so that each tongue fits into each groove of said tooth.

Cette conformation permet d'éviter un déplacement axial par rapport au rotor de chaque partie du moyen anti-arrachement lors de l'imbrication de chaque dent dans chaque évidement correspondant du stator.This configuration makes it possible to avoid an axial displacement with respect to the rotor of each part of the anti-tearing means during the nesting of each tooth in each corresponding recess of the stator.

Idéalement, chaque zone fusible est établie au niveau de l'axe de symétrie du moyen anti-arrachement. Ceci permet une division du moyen anti-arrachement en deux parties égales et ainsi entraîner chaque dent de chacune des parties du moyen anti-arrachement en même temps dans les évidements correspondant du stator afin de bloquer le mouvement du rotor plus efficacement.Ideally, each fusible zone is established at the level of the axis of symmetry of the anti-tearing means. This enables a division of the anti-chipping means into two equal parts and thus driving each tooth of each of the parts of the anti-chipping means at the same time into the corresponding recesses of the stator in order to block the movement of the rotor more effectively.

Encore idéalement, l'axe de symétrie du moyen anti-arrachement est l'axe longitudinal (X).Again ideally, the axis of symmetry of the anti-tearing means is the longitudinal axis (X).

Dans un mode de réalisation, le moyen anti-arrachement présente au moins une encoche de part et d'autre de chaque zone fusible. Chaque encoche a l'avantage de faire céder le moyen anti-arrachement au niveau de chaque zone fusible plus facilement, ainsi, dès l'introduction d'un objet non adéquat dans le verrou, chaque point de fusion cède et le mouvement rotatoire du rotor est empêché.In one embodiment, the anti-tearing means has at least one notch on either side of each fuse zone. Each notch has the advantage of causing the anti-tearing means to give way at each fusible zone more easily, thus, as soon as an unsuitable object is introduced into the lock, each melting point gives way and the rotary movement of the rotor is prevented.

Dans un autre mode de réalisation, chaque extrémité du moyen anti-arrachement présente deux dents diamétralement opposées, les axes d'extension desdites dents étant parallèles entres eux.In another embodiment, each end of the anti-pullout means has two diametrically opposed teeth, the extension axes of said teeth being parallel to each other.

Encore dans un autre mode de réalisation préféré, le verrou permet de verrouiller et/ou déverrouiller un ouvrant de véhicule automobile ou une colonne de direction d'un véhicule automobile.In yet another preferred embodiment, the lock makes it possible to lock and / or unlock an opening of a motor vehicle or a steering column of a motor vehicle.

Sur cette figure, des logements 13 sont représentés sur le rotor 12, autorisant l'insertion de paillettes (non représentées), retenant ou libérant ainsi le mouvement du rotor 12 par rapport au stator 14. Le rotor 12 est inséré à l'intérieur du stator 14 divisé en deux éléments 14a et 14b avec un élément supérieur 14a et un élément inférieur 14b. Ces deux éléments 14a et 14b du stator 14 s'assemblent et enferment le rotor 12 contenant le moyen anti-arrachement 11.The figure 2 shows part of the lock according to the invention. An anti-tearing means 11 which will be described in more detail in the figure 3 following is introduced into the rotor 12 at a specific location which is the end of the rotor 12 closest to the introduction duct (not shown) allowing the insertion of the appropriate key for unlocking an opening, for example. In this figure, housings 13 are shown on the rotor 12, allowing the insertion of flakes (not shown), thus retaining or releasing the movement of the rotor 12 relative to the stator 14. The rotor 12 is inserted inside the rotor. stator 14 divided into two elements 14a and 14b with an upper element 14a and a lower element 14b. These two elements 14a and 14b of the stator 14 are assembled and enclose the rotor 12 containing the anti-tearing means 11.

La figure 3 montre le moyen anti-arrachement 11 conformément à l'invention. Un évidement de forme rectangulaire est réalisée au centre du moyen anti-arrachement 11 afin de faire traverser la clé déverrouillant un ouvrant de véhicule par exemple. Le moyen anti-arrachement 11 présente un axe de symétrie selon l'axe longitudinal X où au moins une zone fusible est mise en place. Sur cette figure, deux zones fusibles 15a et 15b apparaissent, ayant la fonction de séparer en deux parties égales le moyen anti-arrachement 11 lors de l'introduction d'un objet inadapté dans le verrou.The figure 3 shows the anti-tearing means 11 according to the invention. A rectangular-shaped recess is made in the center of the anti-tearing means 11 in order to pass through the key unlocking a vehicle opening for example. The anti-tearing means 11 has an axis of symmetry along the longitudinal axis X where at least one fusible zone is placed. In this figure, two fusible zones 15a and 15b appear, having the function of separating the anti-tearing means 11 into two equal parts when an unsuitable object is introduced into the lock.

On voit également deux encoches 20 réalisées sur le moyen anti-arrachement 11 de part et d'autre de l'axe de symétrie selon l'axe vertical Y en direction de l'évidement central du moyen anti-arrachement 11. Ces encoches 20 permettent de faciliter la rupture des zones fusibles 15a et 15b de par la plus faible largeur et épaisseur du moyen anti-arrachement 11 au niveau de son axe de symétrie selon l'axe Y.We also see two notches 20 made on the anti-tearing means 11 on either side of the axis of symmetry along the vertical axis Y in the direction of the central recess of the anti-tearing means 11. These notches 20 allow to facilitate the breaking of the fusible zones 15a and 15b by virtue of the smaller width and thickness of the anti-tearing means 11 at its axis of symmetry along the Y axis.

Un chanfrein 16 est également réalisé au niveau de l'axe de symétrie selon l'axe X du moyen anti-arrachement 11 dans les deux zones fusibles 15a et 15b. Deux paires de dents 17a, 17b et 17c,17d sont disposées radialement vers l'extérieur sur chaque extrémité de manière symétrique par rapport à l'axe longitudinal X du moyen anti-arrachement 11. Des congés 19 sont également réalisés sur le moyen anti-arrachement 11, situés de part et d'autre de chaque dent 17a, 17b, 17c, 17d afin de faire office de butée avec le stator lors de l'imbrication des dents 17a,17b,17c,17d du moyen anti-arrachement 11 dans chaque évidement correspondant du stator.A chamfer 16 is also produced at the level of the axis of symmetry along the X axis of the anti-tearing means 11 in the two fusible zones 15a and 15b. Two pairs of teeth 17a, 17b and 17c, 17d are arranged radially outwardly on each end symmetrically with respect to the longitudinal axis X of the anti-tearing means 11. Fillets 19 are also made on the anti-tearing means. tearing 11, located on either side of each tooth 17a, 17b, 17c, 17d in order to act as stop with the stator during the nesting of the teeth 17a, 17b, 17c, 17d of the anti-pullout means 11 in each corresponding recess of the stator.

La figure 4a montre l'assemblement du rotor 12 à l'intérieur du stator 14, composé par son élément supérieur 14a et son élément inférieur 14b, dans lequel le moyen anti-arrachement 11 est positionné dans le rotor 12 au niveau de son extrémité le plus proche du conduit d'introduction. Sur cette figure, le moyen anti-arrachement 11 est intact, les zones fusibles 15a et 15b sont toujours intactes et les deux paires de dents 17a, 17b et 17c, 17d sont en position de repos, c'est à dire qu'elles ne sont pas imbriquées dans chaque évidement correspondant 18a,18b,18c,18d du stator 14. Le verrou n'a donc pas été forcé et le mouvement rotatoire du rotor 12 dans le stator 14 est permis par l'introduction de la clé adéquate pour déverrouiller un ouvrant de véhicule automobile par exemple.The figure 4a shows the assembly of the rotor 12 inside the stator 14, composed by its upper element 14a and its lower element 14b, in which the anti-tearing means 11 is positioned in the rotor 12 at the level of its end closest to the introductory conduit. In this figure, the anti-tearing means 11 is intact, the fusible zones 15a and 15b are still intact and the two pairs of teeth 17a, 17b and 17c, 17d are in the rest position, that is to say that they are not are not nested in each corresponding recess 18a, 18b, 18c, 18d of the stator 14. The lock has therefore not been forced and the rotary movement of the rotor 12 in the stator 14 is allowed by the introduction of the appropriate key to unlock a motor vehicle opening, for example.

Au niveau des zones fusibles 15a et 15b, des encoches 20 sont réalisées sur chaque surface de chaque zone fusible à l'exception de la surface intérieure de l'évidement central du moyen anti-arrachement 11 facilitant ainsi la rupture des zones fusibles 15a et 15b lors d'une tentative d'effraction du verrou de l'ouvrant du véhicule automobile. Un chanfrein 16 est également réalisé sur le pourtour des zones fusibles 15a et 15b au niveau des encoches afin d'induire un mouvement des parties du moyen anti-arrachement 11 de façon radial lors de la rupture des zones fusibles 15a et 15b lors d'une tentative d'effraction comme illustré dans la figure suivante.At the level of the fuse zones 15a and 15b, notches 20 are made on each surface of each fuse zone with the exception of the inner surface of the central recess of the anti-tearing means 11 thus facilitating the breaking of the fuse zones 15a and 15b during an attempt to break the lock of the opening of the motor vehicle. A chamfer 16 is also produced around the perimeter of the fusible zones 15a and 15b at the level of the notches in order to induce a movement of the parts of the anti-tearing means 11 radially during the rupture of the fusible zones 15a and 15b during a attempted break-in as shown in the following figure.

Sur l'élément supérieur 14a du stator 14, on voit deux évidements 18a et 18b destinés à recevoir respectivement les deux dents 17a et 17b de la partie supérieure 11a du moyen anti-arrachement 11 lors de la division du moyen anti-arrachement 11 au niveau des zones fusibles 15a et 15b. On note cela plus particulièrement au niveau du chanfrein 16 entraînant l'écartement des deux parties 11a et 11b du moyen anti-arrachement 11 jusqu'à leur logement dans les évidements correspondant prévus dans le stator 14 et sur l'élément inférieur 14b du stator 14.On the upper element 14a of the stator 14, we see two recesses 18a and 18b intended to receive respectively the two teeth 17a and 17b of the upper part 11a of the anti-tearing means 11 during the division of the anti-tearing means 11 at the level fusible zones 15a and 15b. This is more particularly noted at the level of the chamfer 16 causing the separation of the two parts 11a and 11b of the anti-tearing means 11 until they are housed in the corresponding recesses provided in the stator 14 and on the lower element 14b of the stator 14 .

En outre, on voit deux évidements 18c et 18d destinés à recevoir respectivement les deux dents 17c et 17d de la partie inférieure 11b du moyen anti-arrachement 11 lors de la division du moyen anti-arrachement 11 au niveau des zones fusibles 15a et 15b et plus particulièrement au niveau du chanfrein 16 entraînant l'écartement des deux parties 11a et 11b du moyen anti-arrachement 11 jusqu'à leur logement dans les évidements correspondant prévus dans le stator 14 comme illustré dans la figure suivante.In addition, we see two recesses 18c and 18d intended to receive respectively the two teeth 17c and 17d of the lower part 11b of the anti-tearing means 11 during the division of the anti-tearing means 11 at the level of the fusible zones 15a and 15b and more particularly at the level of the chamfer 16 causing the separation of the two parts 11a and 11b of the anti-pullout means 11 until they are housed in the corresponding recesses provided in the stator 14 as illustrated in the following figure.

La figure 4b montre l'assemblement du rotor 12 avec le stator 14 dans lequel le moyen anti-arrachement 11 est divisé en deux parties 11a et 11b du fait de la rupture des zones fusibles 15a et 15b par l'introduction d'un objet inadapté dans le verrou afin de forcer la rotation du rotor 12 dans le stator 14 dans le but de déverrouiller un ouvrant de véhicule automobile par exemple.The figure 4b shows the assembly of the rotor 12 with the stator 14 in which the anti-tearing means 11 is divided into two parts 11a and 11b due to the rupture of the fusible zones 15a and 15b by the introduction of an unsuitable object in the lock in order to force the rotation of the rotor 12 in the stator 14 with the aim of unlocking an opening of a motor vehicle for example.

Les parties 11a et 11b ont toutes deux une forme de H. Chaque dent 17a,17b,17c,17d s'imbrique dans chaque évidement correspondant du stator 14, respectivement 18a,18b,18c,18d, bloquant ainsi le mouvement rotatoire du rotor 12 dans le stator 14. Cette figure montre bien que chaque congé 19 disposé de part et d'autre de chaque dent 17a,17b,17c,17d forme butée contre le stator 14. La figure montre également que les zones fusibles 15a et 15b sont rompues au niveau du chanfrein 16.The parts 11a and 11b both have a shape of H. Each tooth 17a, 17b, 17c, 17d fits into each corresponding recess of the stator 14, respectively 18a, 18b, 18c, 18d, thus blocking the rotary movement of the rotor 12 in the stator 14. This figure clearly shows that each fillet 19 disposed on either side of each tooth 17a, 17b, 17c, 17d forms a stop against the stator 14. The figure also shows that the fusible zones 15a and 15b are broken. at the chamfer 16.

La figure 5 montre une dent 17a imbriquée dans son évidement correspondant 18a de l'élément supérieur 14a du stator 14 du fait de la division du moyen anti-arrachement 11 puis du déplacement radial de la partie 11a du moyen anti-arrachement 11. Sur cette figure, on voit des congés 19 de la partie 1 la du moyen anti-arrachement 11 en contact avec le stator 14 ce qui indique que le déplacement radial de la partie 11a du moyen anti-arrachement 11 a été effectué jusqu'à venir en butée avec l'élément supérieur 14a du stator et donc que le rotor 12 ne peut pas être amené à effectuer un mouvement de rotation.The figure 5 shows a tooth 17a nested in its corresponding recess 18a of the upper element 14a of the stator 14 due to the division of the anti-tearing means 11 and then the radial displacement of the part 11a of the anti-tearing means 11. In this figure, we see sees leaves 19 of part 1 la of the anti-tearing means 11 in contact with the stator 14 which indicates that the radial displacement of part 11a of the anti-tearing means 11 has been carried out until it comes into abutment with the upper element 14a of the stator and therefore the rotor 12 cannot be caused to perform a rotational movement.

La figure 5 montre également la conformation spécifique de l'évidement qui présente trois languettes 21 disposées au milieu de chaque surface intérieure de l'évidement. Chaque dent a donc une conformation complémentaire à celui de l'évidement, ce qui induit que chaque dent présente trois rainures disposées à recevoir les languettes 21 de l'évidement de façon à ce que chaque dent s'imbrique dans chacun de ses évidements lors du déplacement radial de chacune des parties du moyen anti-arrachement 11.The figure 5 also shows the specific conformation of the recess which has three tabs 21 arranged in the middle of each interior surface of the recess. Each tooth therefore has a conformation complementary to that of the recess, which means that each tooth has three grooves arranged to receive the tongues 21 of the recess so that each tooth fits into each one. of its recesses during the radial displacement of each of the parts of the anti-tearing means 11.

Ces conformations permettent une imbrication plus solide de la dent dans son évidement et ainsi bloquer le déplacement axial des parties du moyen anti-arrachement 11 par rapport au rotor 12.These conformations allow a more solid nesting of the tooth in its recess and thus block the axial displacement of the parts of the anti-tearing means 11 relative to the rotor 12.

Dans les paragraphes suivants, le mode de fonctionnement de la présente invention est expliqué de façon non limitatif.In the following paragraphs, the mode of operation of the present invention is explained without limitation.

Lorsqu'un objet inadéquat est introduit dans un conduit d'introduction tel que celui représenté dans la figure 1, dans le but de forcer le déverrouillage d'un ouvrant de véhicule par exemple, la première pièce rencontrée par l'objet en question au niveau du rotor 12 est le moyen anti-arrachement 11 conforme à l'invention comme celui représenté à la figure 3, ce qui a l'avantage de bloquer directement le mouvement de rotation du rotor 12 afin d'empêcher le déverrouillage de l'ouvrant et ainsi l'éventuel vol du véhicule.When an unsuitable object is introduced into an introduction duct such as the one shown in the figure 1 , in order to force the unlocking of a vehicle opening for example, the first part encountered by the object in question at the level of the rotor 12 is the anti-tearing means 11 in accordance with the invention, such as that shown in figure 3 , which has the advantage of directly blocking the rotational movement of the rotor 12 in order to prevent the unlocking of the opening and thus the possible theft of the vehicle.

En effet, lorsqu'un individu introduit un objet pour forcer le verrou afin de déverrouiller l'ouvrant, cet objet force sur le moyen anti-arrachement 11 et plus particulièrement sur les zones fusibles 15a et 15b représentées sur la figure 3 du moyen anti-arrachement 11 qui sont plus fragiles que le reste du moyen anti-arrachement 11 et cèdent sous la pression de l'objet ce qui induit une division en deux parties du moyen anti-arrachement 11 au niveau de son axe de symétrie selon l'axe longitudinal X.Indeed, when an individual introduces an object to force the lock in order to unlock the opening, this object forces on the anti-tearing means 11 and more particularly on the fusible zones 15a and 15b shown on the figure. figure 3 of the anti-tearing means 11 which are more fragile than the rest of the anti-tearing means 11 and yield under the pressure of the object which induces a division into two parts of the anti-tearing means 11 at the level of its axis of symmetry according to the longitudinal axis X.

Plus précisément, c'est le chanfrein 16 représenté à la figure 3, réalisé au niveau de l'axe de symétrie X dans les zones fusibles 15a et 15b, qui initie, lors de la rupture des zones fusibles 15a et 15b par l'introduction d'un objet inadapté dans le verrou, l'écartement radial des deux parties 11a et 11b du moyen anti-arrachement 11, l'un vers le haut et l'autre vers le bas, afin que les dents 17a,17b,17c,17d du moyen anti-arrachement 11 s'imbriquent dans chaque évidement correspondant du stator, ce qui entraîne le blocage du mouvement rotatoire du rotor dans le stator. Cela fonctionne aussi si l'axe de symétrie est différent.More precisely, it is the chamfer 16 shown on figure 3 , carried out at the level of the axis of symmetry X in the fusible zones 15a and 15b, which initiates, upon rupture of the fusible zones 15a and 15b by the introduction of an unsuitable object into the lock, the radial spacing of the two parts 11a and 11b of the anti-tearing means 11, one upwards and the other downwards, so that the teeth 17a, 17b, 17c, 17d of the anti-tearing means 11 fit into each corresponding recess of the stator, which causes the rotational movement of the rotor to be blocked in the stator. It also works if the axis of symmetry is different.

En effet, lors de la rupture des zones fusibles 15a et 15b, l'objet introduit dans le verrou exerce une poussée sur le chanfrein 16 réalisé sur chaque zone fusible 15a et 15b ce qui amène un déplacement radial simultané des parties 11a et 11b du moyen anti-arrachement 11. La partie supérieure 11a du moyen anti-arrachement 11 se déplace radialement jusqu'à se loger dans les évidements 18a et 18b de l'élément supérieur 14a du stator 14 par l'intermédiaire respectivement des dents 17a et 17b présentes sur la partie supérieure 1 la du moyen anti-arrachement 11.Indeed, during the rupture of the fusible zones 15a and 15b, the object introduced into the lock exerts a thrust on the chamfer 16 produced on each fusible zone 15a and 15b which brings about a simultaneous radial displacement of the parts 11a and 11b of the means. anti-tearing 11. The upper part 11a of the anti-tearing means 11 moves radially until it is housed in the recesses 18a and 18b of the upper element 14a of the stator 14 by means respectively of the teeth 17a and 17b present on the upper part 11a of the anti-tearing means 11.

La partie inférieure 11b du moyen anti-arrachement 11 se déplace radialement jusqu'à se loger dans les évidements 18c et 18d de l'élément inférieur 14b du stator 14 par l'intermédiaire respectivement des dents 17c et 17d présentes sur la partie inférieure 11b du moyen anti-arrachement 11 comme représenté sur la figure 4b. De par le déplacement simultané des parties 11a et 11b du moyen anti-arrachement 11, chaque dent 17a,17b,17c,17d s'imbrique en même temps dans l'évidement correspondant, respectivement 18a, 18b,18c,18d.The lower part 11b of the anti-pullout means 11 moves radially until it is housed in the recesses 18c and 18d of the lower element 14b of the stator 14 by means respectively of the teeth 17c and 17d present on the lower part 11b of the anti-tearing means 11 as shown in figure 4b . By the simultaneous displacement of the parts 11a and 11b of the anti-pullout means 11, each tooth 17a, 17b, 17c, 17d fits at the same time in the corresponding recess, respectively 18a, 18b, 18c, 18d.

C'est lorsque les congés 19 présents sur chaque partie 11a et 11b du moyen anti-arrachement 11 entrent en contact avec le stator 14 que le déplacement radial des parties 11a et 11b du moyen anti-arrachement s'arrête, les dents du moyen anti-arrachement 11 ne vont pas jusqu'à boucher les évidements du stator 14 du fait de la butée créée par les congés 19 avec le stator 14 comme illustré dans la figure 5.It is when the fillets 19 present on each part 11a and 11b of the anti-tearing means 11 come into contact with the stator 14 that the radial displacement of the parts 11a and 11b of the anti-tearing means stops, the teeth of the anti-tearing means -tearing 11 do not go so far as to block the recesses of the stator 14 due to the stop created by the fillets 19 with the stator 14 as illustrated in figure 5 .

Les parties 11a et 11b du moyen anti-arrachement 11, lorsqu'elles sont imbriquées dans les évidements 18a,18b,18c,18d du stator 14 par l'intermédiaire respectivement des dents 17a,17b,17c,17d, bloquent le mouvement rotatoire du rotor 12. Dans l'exemple donné, l'ouvrant du véhicule automobile ne peut donc pas être déverrouillé.The parts 11a and 11b of the anti-tearing means 11, when they are nested in the recesses 18a, 18b, 18c, 18d of the stator 14 via respectively the teeth 17a, 17b, 17c, 17d, block the rotary movement of the rotor 12. In the example given, the opening of the motor vehicle cannot therefore be unlocked.
