Description

Le domaine technique de l'invention est celui des verrous, en particulier destinés à être montés dans des mécanismes de fermeture d'ouvrants de véhicule automobile.The technical field of the invention is that of locks, in particular intended to be fitted in mechanisms for closing motor vehicle doors.

Un verrou classique comporte un corps fixe appelé stator, monté solidaire du mécanisme de fermeture et/ou de l'ouvrant, un rotor, de forme générale cylindrique, emboîté dans le corps fixe et présentant un logement pouvant accueillir une clé. Un jeu de paillettes, mobiles radialement, retient ou libère en rotation le rotor par rapport au corps fixe. Les paillettes sont déplacées lorsqu'une clé est introduite dans le logement du rotor, et le rotor n'est libéré en rotation que lorsque la clé est conforme. C'est ensuite la rotation du rotor qui déclenche le déverrouillage du mécanisme de fermeture.A conventional lock comprises a fixed body called a stator, mounted integral with the closing mechanism and / or the opening, a rotor, of generally cylindrical shape, fitted into the fixed body and having a housing capable of accommodating a key. A set of radially movable spangles retains or releases the rotor in rotation relative to the fixed body. The chaff is displaced when a key is inserted into the rotor housing, and the rotor is released to rotate only when the key is compliant. It is then the rotation of the rotor which triggers the unlocking of the closing mechanism.

Le rotor est configuré pour être relié à une serrure par un cardan au niveau d'une interface de liaison configurée pour recevoir une première extrémité dudit cardan. Ce cardan est fixé à une seconde extrémité, opposée à la première ; à une serrure de sorte que la rotation du rotor par la clé entraine le déverrouillage de la serrure.The rotor is configured to be connected to a lock by a gimbal at a link interface configured to receive a first end of said gimbal. This gimbal is fixed at a second end, opposite to the first; to a lock so that the rotation of the rotor by the key unlocks the lock.

Pour éviter le désassemblage entre le rotor et le cardan au niveau de l'interface de liaison, dues aux vibrations du véhicule lorsque celui-ci est en mouvement, une solution a été proposée, qui consiste en un élément disposé autour du rotor et recouvrant l'interface de liaison.To avoid disassembly between the rotor and the gimbal at the connection interface, due to vibrations of the vehicle when the latter is in motion, a solution has been proposed, which consists of an element arranged around the rotor and covering the 'link interface.

Cette solution présente plusieurs inconvénients, notamment une mauvaise position du cardan dans le verrou. De plus, lors de la sollicitation du verrou, particulièrement lors de la rotation du rotor, l'élément recouvrant l'interface de liaison est mal maintenu. Enfin, l'assemblage du cardan avec le rotor doit être effectué en amont de celui du dispositif de verrouillage, ce qui complexifie l'assemblage du dispositif de verrouillage. Le document FR2912174 décrit un procédé de fabrication d'un verrou rotatif de véhicule automobile de l'état de la technique.This solution has several drawbacks, in particular a bad position of the gimbal in the lock. In addition, when the latch is urged, particularly during rotation of the rotor, the element covering the link interface is poorly maintained. Finally, the assembly of the cardan shaft with the rotor must be carried out upstream of that of the locking device, which complicates the assembly of the locking device. The document FR2912174 describes a method of manufacturing a rotary lock for a motor vehicle of the state of the art.

La présente invention est définie par la revendication 1 et vise à remédier à au moins un de ces inconvénients en fournissant un assemblage comprenant un verrou et un cardan, le verrou comprenant un rotor et un stator, ledit rotor étant disposé à l'intérieur dudit stator et configuré pour être mobile en rotation autour d'un axe de rotation par rapport au stator, le rotor étant configuré pour être relié à une serrure par ledit cardan au niveau d'une interface de liaison configurée pour recevoir une extrémité dudit cardan, dans lequel le verrou comporte un élément de protection fixé audit stator et configuré pour recouvrir au moins en partie l'interface de liaison du rotor avec le cardan.The present invention is defined by claim 1 and aims to remedy at least one of these drawbacks by providing an assembly comprising a lock and a gimbal, the lock comprising a rotor and a stator, said rotor being disposed inside said stator and configured to be movable in rotation about an axis of rotation relative to the stator, the rotor being configured to be connected to a lock by said gimbal at a link interface configured to receive one end of said gimbal, in which the lock comprises a protection element fixed to said stator and configured to cover at least part of the connection interface of the rotor with the gimbal.

La fixation de l'élément de protection au stator permet de ne pas interférer avec la rotation du rotor, entraînant une position adéquate du cardan dans le rotor. De plus, l'élément de protection évite le décrochement de la liaison entre l'extrémité du cardan et le rotor. Enfin, l'élément de protection offre une sécurité antivol accrue d'un ouvrant, protégeant la liaison entre le rotor et le cardan.Attaching the protective element to the stator ensures that it does not interfere with the rotation of the rotor, resulting in a proper position of the gimbal in the rotor. In addition, the protection element prevents the connection between the end of the gimbal and the rotor from becoming detached. Finally, the protection element offers an increased anti-theft security of an opening, protecting the connection between the rotor and the gimbal.

L'élément de protection peut être un élément rapporté sur le stator ou l'élément de protection et le stator peuvent former qu'une seule pièce.The protection element can be an element attached to the stator or the protection element and the stator can form a single piece.

En effet, l'élément de protection et le stator sont deux éléments solidaires en mouvement mais peuvent soit former qu'une seule pièce ou deux pièces rapportées l'une sur l'autre ;Indeed, the protection element and the stator are two integral moving elements but can either form a single part or two parts attached to one another;

Avantageusement, le stator est formé par deux coquilles, l'une de ces coquilles comprenant l'élément de protection.Advantageously, the stator is formed by two shells, one of these shells comprising the protection element.

Avantageusement encore, l'élément de protection est rapporté au stator.Also advantageously, the protection element is attached to the stator.

Notamment, une extrémité du stator comporte au moins une rainure configurée pour recevoir au moins une languette correspondante de l'élément de protection.In particular, one end of the stator comprises at least one groove configured to receive at least one corresponding tongue of the protective element.

Selon une possibilité, l'élément de protection est surmoulé sur le stator.According to one possibility, the protection element is molded onto the stator.

Ceci offre un assemblage du verrou simplifié.This provides for simplified latch assembly.

Selon l'invention, le verrou comprend une tige, ledit rotor comprend au moins un logement de rotor configuré pour recevoir la tige, ladite extrémité dudit cardan comprend au moins un logement de cardan configuré pour recevoir la tige, ladite tige étant configurée pour lier ledit rotor audit cardan.

The housing has a flare, configured to clamp the rod.

Dans un mode de réalisation, le rotor est configuré pour se déplacer entre une première position et une deuxième position décalée angulairement l'une par rapport à l'autre selon l'axe de rotation.In one embodiment, the rotor is configured to move between a first position and a second position angularly offset from one another along the axis of rotation.

Dans un autre mode de réalisation, l'élément de protection est configuré pour être en regard de l'au moins un logement de rotor lorsque le rotor est en première position, l'au moins un logement de rotor étant libre lorsque ledit rotor est en deuxième position. La deuxième position permet à la tige d'être insérée et la première position emprisonne la tige.In another embodiment, the protective element is configured to be facing the at least one rotor housing when the rotor is in the first position, the at least one rotor housing being free when said rotor is in position. second position. The second position allows the rod to be inserted and the first position traps the rod.

La figure 1 montre un verrou 1 relié à une serrure 2 par un cardan 3. La serrure 2 est configurée pour verrouiller et/ou déverrouiller l'ouverture d'un ouvrant, de véhicule automobile par exemple.The figure 1 shows a lock 1 connected to a lock 2 by a universal joint 3. The lock 2 is configured to lock and / or unlock the opening of an opening, of a motor vehicle for example.

Le verrou 1 comprend un rotor 4 inséré à l'intérieur d'un stator 5.The lock 1 comprises a rotor 4 inserted inside a stator 5.

L'une des extrémités du verrou 1 comporte un capuchon 6 d'insertion d'une clé configurée pour mettre en mouvement le rotor 4 selon un axe de rotation A. L'autre extrémité du verrou 1, soit l'extrémité du rotor 4 la plus éloignée du capuchon 6 d'insertion de la clé, reçoit une extrémité du cardan 3 configurée pour être assemblée dans le rotor 4. Un élément de protection 7 recouvre au moins une partie du rotor 4.One of the ends of the lock 1 comprises a cap 6 for inserting a key configured to set the rotor 4 in motion along an axis of rotation A. The other end of the lock 1, i.e. the end of the rotor 4 la further away from the key insertion cap 6, receives an end of the gimbal 3 configured to be assembled in the rotor 4. A protection element 7 covers at least a part of the rotor 4.

Le cardan 3 est également inséré, par une extrémité opposée à l'extrémité insérée dans le rotor 4, dans la serrure 2.The gimbal 3 is also inserted, by an end opposite to the end inserted in the rotor 4, in the lock 2.

Le cardan 3 est sous la forme d'une tige rigide ou d'un câble présentant trois parties. Une première partie 8 est apte à être introduite à l'intérieur du rotor 4, une deuxième partie 9 est apte à être introduite à l'intérieur de la serrure 2 et une troisième partie 10 relie les première et deuxième parties 8 et 9.The gimbal 3 is in the form of a rigid rod or a cable having three parts. A first part 8 is able to be inserted inside the rotor 4, a second part 9 is able to be inserted inside the lock 2 and a third part 10 connects the first and second parts 8 and 9.

La figure 2 montre le verrou 1 dépourvu de son stator 5.The figure 2 shows lock 1 without its stator 5.

Le verrou 1 présente une pluralité de paillettes 11 configurées pour retenir ou libérer en rotation le rotor 4 par rapport au stator 5.The latch 1 has a plurality of straws 11 configured to retain or release in rotation the rotor 4 relative to the stator 5.

L'extrémité du rotor 4, la plus éloignée du capuchon 6 d'insertion de la clé, comporte deux logements 12a et 12b, ici des orifices, situés en regard l'un de l'autre et disposés selon un axe, l'axe transversal B étant transversal à un axe A de rotation du rotor.The end of the rotor 4, the farthest from the key insertion cap 6, has two housings 12a and 12b, here orifices, located opposite one another and arranged along an axis, the axis transverse B being transverse to an axis A of rotation of the rotor.

La première partie 8 du cardan 3, comportant l'extrémité configurée pour s'insérer à l'intérieur du rotor 4, présente un logement 13, ici un orifice.The first part 8 of the gimbal 3, comprising the end configured to fit inside the rotor 4, has a housing 13, here an orifice.

Le logement 13 de l'extrémité de la première partie 8 du cardan 3 est configuré pour venir s'aligner avec chacun des logements 12a et 12b du rotor 4 lors de l'insertion de l'extrémité de la première partie 8 dans le rotor 4.The housing 13 of the end of the first part 8 of the gimbal 3 is configured to come into line with each of the housings 12a and 12b of the rotor 4 when inserting the end of the first part 8 into the rotor 4 .

Un élément de fixation, ici une tige 14, notamment une clavette, est configurée pour traverser les logements 12a ou 12b du rotor 4 et le logement 13 de l'extrémité de la première partie 8 du cardan 3 de manière à fixer le cardan 3 dans le rotor 4.A fixing element, here a rod 14, in particular a key, is configured to pass through the housings 12a or 12b of the rotor 4 and the housing 13 of the end of the first part 8 of the gimbal 3 so as to fix the gimbal 3 in rotor 4.

Lorsque la tige 14 assemble le cardan 3 avec le rotor 4, chaque extrémité de la tige 14 obstrue le logement 12a ou 12b correspondant.When the rod 14 assembles the gimbal 3 with the rotor 4, each end of the rod 14 obstructs the corresponding housing 12a or 12b.

Alternativement, un seul des logements 12a ou 12b pourrait être traversé par la tige 14.Alternatively, only one of the housings 12a or 12b could be crossed by the rod 14.

Comme cela est représenté sur la figure 3, un élément de protection 7 est configuré pour recouvrir au moins en partie le rotor 4 au niveau de ses logements 12a et 12b de manière à ce que la tige 14 ne puisse pas s'extraire du rotor 4 et ainsi désassembler le cardan 3 et le rotor 4.As shown in the figure 3 , a protective element 7 is configured to cover at least part of the rotor 4 at the level of its housings 12a and 12b so that the rod 14 cannot be extracted from the rotor 4 and thus disassemble the cardan shaft 3 and the rotor 4.

L'élément de protection 7 peut être un élément rapporté sur le stator 5 ou l'élément de protection 7 et le stator 5 peuvent former qu'une seule pièce.The protection element 7 can be an element attached to the stator 5 or the protection element 7 and the stator 5 can form a single piece.

En effet, l'élément de protection 7 et le stator 5 sont deux éléments solidaires en mouvement mais peuvent soit former qu'une seule pièce ou deux pièces rapportées l'une sur l'autre.Indeed, the protection element 7 and the stator 5 are two integral moving elements but can either form a single part or two parts attached to one another.

La figure 3 montre le verrou 1 comprenant le rotor 4 inséré dans le stator 5. Le rotor est dans une première position, matérialisée par la disposition de l'axe des logements 12a et 12b de manière parallèle à l'axe transversal B du verrou 1.The figure 3 shows the latch 1 comprising the rotor 4 inserted into the stator 5. The rotor is in a first position, materialized by the arrangement of the axis of the housings 12a and 12b parallel to the transverse axis B of the latch 1.

Le stator présente une ouverture 19 par laquelle l'extrémité du rotor 4 la plus éloignée du capuchon 6 d'insertion de la clé est accessible par l'extérieur du stator 5. L'extrémité de la première partie 8 du cardan 3 est insérée à l'intérieur du rotor 4, et plus précisément, le logement 13 de l'extrémité de la première partie 8 du cardan 3 est inséré dans le rotor 4, de manière à ce que le logement 13 soit axé avec chacun des logements 12a et 12b du rotor 4.The stator has an opening 19 through which the end of the rotor 4 furthest from the key insertion cap 6 is accessible from the outside of the stator 5. The end of the first part 8 of the gimbal 3 is inserted through the interior of the rotor 4, and more precisely, the housing 13 of the end of the first part 8 of the gimbal 3 is inserted into the rotor 4, so that the housing 13 is centered with each of the housings 12a and 12b rotor 4.

Le logement 13 présente un évasement, serrant ainsi la tige 14 lorsque celle-ci lie le cardan 3 et le rotor 4.The housing 13 has a flare, thus tightening the rod 14 when the latter connects the gimbal 3 and the rotor 4.

La tige 14 assemble le rotor 4 avec le cardan 3 en traversant un des logements 12a ou 12b et 13. La tige 14 est parallèle à l'axe transversal B du verrou 1.The rod 14 assembles the rotor 4 with the gimbal 3 by passing through one of the housings 12a or 12b and 13. The rod 14 is parallel to the transverse axis B of the lock 1.

L'élément de protection 7 recouvre une partie du rotor 4 de manière à bloquer la tige 14 dans le stator 5 lorsque le rotor 4 est dans sa première position.The protective element 7 covers part of the rotor 4 so as to block the rod 14 in the stator 5 when the rotor 4 is in its first position.

Le rotor 4 étant de forme cylindrique, l'élément de protection 7 forme un demi-cercle autour d'une partie du rotor 4, de manière à obstruer les deux logements 12a et 12b du rotor 4.The rotor 4 being of cylindrical shape, the protective element 7 forms a semicircle around a part of the rotor 4, so as to obstruct the two housings 12a and 12b of the rotor 4.

L'élément de protection 7 est rapporté au stator 5.The protection element 7 is attached to the stator 5.

Plus précisément, l'élément de protection 7 est configuré pour s'associer au stator 5 au niveau de son extrémité la plus proche de l'interface de liaison entre le cardan 3 et le verrou 1.More precisely, the protection element 7 is configured to associate with the stator 5 at its end closest to the link interface between the gimbal 3 and the lock 1.

L'extrémité du stator 5 recevant l'élément de protection 7 présente deux rainures 15a et 15b disposées perpendiculairement par rapport à l'axe de rotation A du rotor 4. Ces deux rainures 15a et 15b sont configurées pour recevoir une languette 16a et 16b correspondante présentes sur l'élément de protection 7.The end of the stator 5 receiving the protective element 7 has two grooves 15a and 15b arranged perpendicular to the axis of rotation A of the rotor 4. These two grooves 15a and 15b are configured to receive a corresponding tongue 16a and 16b. present on the protective element 7.

En effet, l'élément de protection 7 comporte deux bras, ici les languettes 16a et 16b, solidaires de la forme en demi-cercle de l'élément de protection 7 recouvrant au moins une partie du rotor 4.Indeed, the protection element 7 comprises two arms, here the tongues 16a and 16b, integral with the semi-circular shape of the protection element 7 covering at least part of the rotor 4.

Le surmoulage de l'élément de protection 7 au stator 5 est également envisageable.The overmolding of the protective element 7 to the stator 5 is also possible.

La figure 4 montre l'élément de protection 7 disposé sur au moins une partie du rotor 4.The figure 4 shows the protection element 7 arranged on at least part of the rotor 4.

L'élément de protection 7 présente une face recouvrant au moins une partie du rotor 4. L'autre face de l'élément de protection 7, opposée à la précédente, présente des nervures.The protection element 7 has a face covering at least part of the rotor 4. The other face of the protection element 7, opposite to the previous one, has ribs.

En effet, trois nervures 17a, 17b et 17c sont réparties uniformément sur la face opposée à la face recouvrant au moins une partie du rotor 4. Ces nervures 17a, 17b et 17c augmentent la résistance et la rigidité de l'élément de protection 7.Indeed, three ribs 17a, 17b and 17c are distributed uniformly on the face opposite to the face covering at least part of the rotor 4. These ribs 17a, 17b and 17c increase the strength and rigidity of the protective element 7.

L'élément de protection 7 est limitrophe à l'extrémité du stator 5 la plus éloignée du capuchon 6 d'insertion de la clé.The protection element 7 is adjacent to the end of the stator 5 furthest from the cap 6 for inserting the key.

L'élément de protection 7 recouvre également toute la longueur, parallèle à l'axe de rotation A, d'au moins une partie du rotor 4 par rapport à l'ouverture 19 du stator 5.The protective element 7 also covers the entire length, parallel to the axis of rotation A, of at least part of the rotor 4 relative to the opening 19 of the stator 5.

Les figures 5a, 5b et 5c représentent plusieurs étapes d'assemblage du cardan 3 sur le verrou 1.The figures 5a, 5b and 5c represent several stages of assembly of the gimbal 3 on the lock 1.

Sur ces figures, le stator 5 est composé de deux coquilles 18a et 18b, s'emboitant l'une dans l'autre par complémentarité de forme.In these figures, the stator 5 is made up of two shells 18a and 18b, fitting into each other by complementary shape.

La coquille 18a comporte l'élément de protection 7. Il est également envisageable que l'élément de protection 7 soit supporté par la coquille 18b.The shell 18a comprises the protective element 7. It is also conceivable that the protective element 7 is supported by the shell 18b.

Dans les paragraphes suivants, la méthode d'assemblage du cardan 3 sur le verrou 1 est explicitée en références aux figures 5a, 5b et 5c.In the following paragraphs, the method of assembling the gimbal 3 on the lock 1 is explained with reference to the figures 5a, 5b and 5c .

Sur la figure 5a, les deux coquilles 18a et 18b composant le stator 5 sont assemblées de manière à emprisonner le rotor 4.On the figure 5a , the two shells 18a and 18b making up the stator 5 are assembled so as to trap the rotor 4.

L'élément de protection 7, supporté par la coquille 18a, recouvre partiellement l'extrémité du rotor 4 la plus éloignée du capuchon 6 d'insertion de la clé lorsque les coquilles 18a et 18b sont emboîtées.The protection element 7, supported by the shell 18a, partially covers the end of the rotor 4 furthest from the key insertion cap 6 when the shells 18a and 18b are fitted.

Le rotor 4 est dans sa première position, les logements 12a et 12b situés sur le rotor 4 sont obstrués par l'élément de protection 7. La tige 14 ne peut donc pas être insérée dans le rotor 4 afin de lier le cardan 3 avec le rotor 4.The rotor 4 is in its first position, the housings 12a and 12b located on the rotor 4 are blocked by the protection element 7. The rod 14 can therefore not be inserted into the rotor 4 in order to link the gimbal 3 with the rotor 4.

Sur la figure 5b, le rotor 4 est dans sa deuxième position. En effet, le rotor 4 étant mobile en rotation selon l'axe A, le rotor 4 est décalé d'un certain angle, notamment de plus de 10°, entre sa première position et sa deuxième position.On the figure 5b , the rotor 4 is in its second position. Indeed, the rotor 4 being movable in rotation along the axis A, the rotor 4 is offset by a certain angle, in particular by more than 10 °, between its first position and its second position.

La deuxième position du rotor 4 peut être amenée par la rotation selon l'axe A de la clé correspondante lorsque celle-ci est insérée dans le verrou 1 au niveau du capuchon 6.The second position of the rotor 4 can be brought about by the rotation along the axis A of the corresponding key when the latter is inserted into the lock 1 at the level of the cap 6.

Lorsque le rotor 4 est dans sa deuxième position, l'un des logements 12a ou 12b n'est plus obstrué par l'élément de protection 7. Cette deuxième position permet d'insérer la tige 14 à travers le logement 12a ou 12b qui n'est pas condamné par l'élément de protection 7, comme illustré sur la figure 5c.When the rotor 4 is in its second position, one of the housings 12a or 12b is no longer obstructed by the protection element 7. This second position allows the rod 14 to be inserted through the housing 12a or 12b which is no longer blocked. 'is not blocked by the protection element 7, as illustrated on the figure 5c .

Sur la figure 5c, l'extrémité de la première partie 8 du cardan 3 est insérée dans le rotor 4 de manière à ce que son logement 13 soit aligné avec les logements 12a et 12b du rotor 4. Puis, la tige 14 est insérée de manière à traverser le logement 12a ou 12b qui n'est pas obstrué par l'élément de protection 7 mais également le logement 13 de l'extrémité de la première partie 8 du cardan 3 jusqu'à ce que la tige 14 soit en butée contre l'élément de protection 7 au niveau du logement 12a ou 12b qui n'a pas été traversé par la tige 14.On the figure 5c , the end of the first part 8 of the gimbal 3 is inserted into the rotor 4 so that its housing 13 is aligned with the housings 12a and 12b of the rotor 4. Then, the rod 14 is inserted so as to pass through the housing 12a or 12b which is not obstructed by the protection element 7 but also the housing 13 of the end of the first part 8 of the gimbal 3 until the rod 14 is in abutment against the protection 7 at the level of the housing 12a or 12b which has not been crossed by the rod 14.

Une fois le rotor 4 et le cardan 3 liés par la tige 14, le rotor 4 est déplacé dans sa première position de manière à ce que la tige 14 soit emprisonnée par l'élément de protection 7.Once the rotor 4 and the gimbal 3 linked by the rod 14, the rotor 4 is moved to its first position so that the rod 14 is trapped by the protective element 7.

Les différents avantages de l'invention sont présentés ci-dessous.The various advantages of the invention are presented below.

L'élément de protection 7, fixé au stator 5, permet de garder une même position du cardan 3 dans le rotor 4 mais également d'éviter le risque de désassemblage du cardan 3 avec le rotor 4 par la migration de la tige 14 en dehors du rotor 4.The protective element 7, fixed to the stator 5, makes it possible to keep the same position of the gimbal 3 in the rotor 4 but also to avoid the risk of disassembly of the gimbal 3 with the rotor 4 by the migration of the rod 14 outside. rotor 4.

En effet, lorsque, par exemple, le véhicule est en mouvement, les vibrations dues à ce mouvement peuvent éjecter la tige 14 de sa position de liaison par le logement 12a ou 12b. Lorsque le véhicule est en mouvement, le rotor 4 est en première position. De ce fait, les logements 12a et 12b sont obstrués par l'élément de protection 7 et donc la migration de la tige 14 en dehors du rotor 4 est impossible, garantissant la liaison du cardan 3 avec le rotor 4.Indeed, when, for example, the vehicle is moving, the vibrations due to this movement can eject the rod 14 from its connection position via the housing 12a or 12b. When the vehicle is in motion, the rotor 4 is in the first position. As a result, the housings 12a and 12b are blocked by the protection element 7 and therefore the migration of the rod 14 outside the rotor 4 is impossible, ensuring the connection of the cardan shaft 3 with the rotor 4.

Le verrouillage et/ou le déverrouillage de l'ouvrant est généralement effectué lorsque le véhicule est à l'arrêt. Il n'y a donc aucun moyen pour que la tige 14 s'extraie du rotor 4 lors de sa rotation.Locking and / or unlocking the opening is generally carried out when the vehicle is stationary. There is therefore no way for the rod 14 to come out of the rotor 4 during its rotation.

L'assemblage du cardan 3 avec le verrou 1 peut être réalisé en dernière étape d'assemblage du dispositif de verrouillage, entraînant une flexibilité de production.The assembly of the gimbal 3 with the lock 1 can be carried out as the last assembly step of the locking device, resulting in production flexibility.

Enfin, l'élément de protection 7 assure la fonction d'antivol. En effet, un voleur ne pourra pas extraire la tige 14 pour déplacer le cardan 3, déverrouillant ainsi le véhicule, puisque la tige 14 est emprisonnée dans le rotor 4 par l'élément de protection 7.Finally, the protection element 7 performs the anti-theft function. Indeed, a thief will not be able to extract the rod 14 to move the gimbal 3, thus unlocking the vehicle, since the rod 14 is trapped in the rotor 4 by the protection element 7.

Bien entendu, la présente invention ne se limite pas aux modes de réalisations présentés.Of course, the present invention is not limited to the embodiments presented.
