Description

La présente invention a pour objet un dispositif d'actionnement d'une serrure de porte de véhicule automobile du type comportant un actionneur antivol agissant d'une part sur un levier de condam­nation de la serrure, susceptible d'occuper une position déverrouillée et une position condamnée, et d'autre part sur un bouton de condamnation intérieur.The subject of the present invention is a device for actuating a motor vehicle door lock of the type comprising an anti-theft actuator acting on the one hand on a lock locking lever, capable of occupying an unlocked position and a position condemned, and on the other hand on an interior condemnation button.

L'évolution des systèmes de condamnation de serrure équipant les portes de véhicules automobiles, en vue d'une amélioration croissante de la sécurité contre le vol, nécessite l'emploi d'un dispositif d'actionnement du type mentionné ci-dessus qui est débrayable et qui permet de verrouiller le bouton de condamnation intérieur afin d'empêcher une ouverture par effraction en agissant directement sur ce bouton de condamnation.The evolution of lock locking systems equipping the doors of motor vehicles, with a view to increasing security against theft, requires the use of an actuation device of the type mentioned above which is disengageable and which makes it possible to lock the interior locking button in order to prevent breaking and entering by acting directly on this locking button.

Toutefois, dans le cas d'une panne électri­que affectant l'actionneur antivol, les systèmes connus ne comportent pas de fonction de secours mécanique permettant un débrayage manuel de la fonction antivol, par exemple par une opération d'ouverture manuelle extérieure de la serrure au moyen d'une clé.However, in the event of an electrical failure affecting the anti-theft actuator, the known systems do not include a mechanical emergency function allowing manual disengagement of the anti-theft function, for example by an external manual opening operation of the lock at by means of a key.

Dans le but de permettre cette intervention de dépannage et de secours, l'invention propose un dispositif d'actionnement du type mentionné plus haut, caractérisé en ce qu'il comprend un levier intermé­diaire sur lequel agit directement l'actionneur anti­vol et auquel est relié le bouton de condamnation, et des premier et des second moyens d'entraînement unidi­rectionnel permettant l'entraînement du levier de condamnation par le levier intermédiaire, respective­ment vers sa position déverrouillée et vers sa posi­tion condamnée, les second moyens d'entraînement unidirectionnel étant susceptibles de s'escamoter de façon à permettre le retour vers sa position déver­rouillée du levier intermédiaire lorsque le levier de condamnation occupe déjà sa position déverrouillée suite à une opération préalable d'ouverture manuelle extérieure de la serrure.In order to allow this breakdown and rescue intervention, the invention provides an actuation device of the type mentioned above, characterized in that it comprises an intermediate lever on which the anti-theft actuator acts directly and to which is connected the locking button, and first and second unidirectional drive means allowing the locking lever to be driven by the intermediate lever, respectively to its unlocked position and to its locked position, the second drive means unidirectional being capable of being retracted so as to allow the return to its unlocked position of the intermediate lever when the locking lever already occupies its unlocked position following a prior operation of manual exterior opening of the lock.

Grâce à cette conception, le levier intermé­diaire de secours peut agir de façon positive sur le levier de condamnation dans le sens du déverrouillage de la serrure, l'escamotage des seconds moyens d'en­traînement unidirectionnel permettant le réenclenche­ment fonctionnel du levier de secours avec le levier de condamnation, lorsqu'il y a eu désynchronisation des mouvements entre ces deux leviers, suite à une action de dépannage à l'aide de la clé de la serrure.Thanks to this design, the intermediate emergency lever can act positively on the locking lever in the direction of unlocking the lock, the retraction of the second unidirectional drive means allowing the functional reset of the emergency lever with the lever of condemnation, when there was desynchronization of the movements between these two levers, following a repair action using the key of the lock.

Selon une autre caractéristique de l'inven­tion, les seconds moyens d'entraînement unidirection­nel comprennent un élément élastique, agencé sur le levier intermédiaire, dont une portion d'extrémité coopère avec une surface d'entraînement prévue en vis à vis sur le levier de condamnation, ce dernier com­portant un profil de came qui provoque la déformation élastique de la portion d'extrémité pour permettre son escamotage.According to another characteristic of the invention, the second unidirectional drive means comprise an elastic element, arranged on the intermediate lever, one end portion of which cooperates with a drive surface provided facing the locking lever. , the latter comprising a cam profile which causes the elastic deformation of the end portion to allow its retraction.

L'élément élastique peut par exemple être constitué par un ressort en fil dont une branche repliée fait saillie hors du plan du levier intermé­diaire pour coopérer avec une première portion du bord du levier de condamnation qui constitue ladite surface d'entraînement.The elastic element may for example be constituted by a wire spring, a folded branch of which protrudes out of the plane of the intermediate lever to cooperate with a first portion of the edge of the locking lever which constitutes said drive surface.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la descrip­tion détaillée de l'invention qui va suivre, pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :

  • La figure 1 est une vue schématique en perspective du dispositif d'actionnement selon l'invention ;
  • La figure 2 est une vue simplifiée, en plan, du levier intermédiaire et du levier de condamnation qui occupent tous deux leur position déverrouillée ;

  • Les figures 9 à 13 sont des vues similaires à celles de la figure 2 représentant les positions respectives occupées successivement par les deux leviers lors de la phase de déverrouillage du levier intermédiaire, effectuée au moyen de l'actionneur antivol, après remise en état de marche du dispositif d'actionnement suite à la panne électrique ayant nécessité l'intervention manuelle extérieure.
Other characteristics and advantages of the invention will appear on reading the detailed description of the invention which follows, for the understanding of which reference will be made to the drawings annexed in which:
  • Figure 1 is a schematic perspective view of the actuating device according to the invention;
  • Figure 2 is a simplified plan view of the intermediate lever and the locking lever which both occupy their unlocked position;

  • Figures 6 and 7 are views similar to those of Figure 2 showing the successive positions occupied by the two levers during an unlocking phase performed by means of the anti-theft actuator.
  • Figure 8 is a view similar to that of Figure 2 in which the two levers occupy their respective positions after an unlocking operation performed manually, from the outside, by means of the key to the lock; and
  • Figures 9 to 13 are views similar to those of Figure 2 showing the respective positions successively occupied by the two levers during the unlocking phase of the intermediate lever, carried out by means of the anti-theft actuator, after restoration in working order of the actuating device following the electrical failure requiring external manual intervention.

On a représenté à la figure 1, sous forme simplifiée, un boîtier de serrure 10 d'une serrure de porte de véhicule automobile. La condamnation et le déverrouillage de la serrure peuvent premièrement être effectués au moyen d'un verrou de portière 12 commandé par une clé 14 qui agit sur la serrure grâce à un levier de commande 16 auquel le verrou 12 est relié fonctionnellement. La liaison fonctionnelle entre le verrou 12 et le levier de commande 16 a été représen­tée de manière symbolique par le trait mixte 18.There is shown in Figure 1, in simplified form, a lock housing 10 of a motor vehicle door lock. Locking and unlocking the lock can first be effected by means of a door lock 12 controlled by a key 14 which acts on the lock by means of a control lever 16 to which the lock 12 is functionally connected. The functional connection between the latch 12 and the control lever 16 has been represented symbolically by the dashed line 18.

La commande de la serrure peut également être effectuée grâce au dispositif d'actionnement 20. Ce dispositif d'actionnement 20 comporte un levier de condamnation 22 monté pivotant sur une platine fixe 24 du boîtier de serrure 10 au moyen d'un axe 26. Le levier de condamnation 22 est susceptible de pivoter autour de l'axe 26 pour occuper une position déverrouillée et une position condamnée définies par des moyens de butées internes au boîtier de serrure 10.The lock can also be controlled by the actuating device 20. This actuating device 20 comprises a locking lever 22 pivotally mounted on a fixed plate 24 of the lock housing 10 by means of an axis 26. The locking lever 22 is capable of pivoting about the axis 26 to occupy an unlocked position and a locked position defined by means of stops internal to the lock housing 10.

Le dispositif d'actionnement comporte également un levier intermédiaire de secours 28 monté pivotant sur la platine fixe 24 au moyen d'un axe 30 disposé au voisinage de l'extrémité libre repliée 32 de la platine 24. Cet agencement du levier intermé­diaire 28 lui permet de pivoter, entre une position déverrouillée et une position condamnée, dans un plan parallèle au plan dans lequel pivote le levier de condamnation 22.The actuating device also comprises an intermediate emergency lever 28 pivotally mounted on the fixed plate 24 by means of an axis 30 disposed in the vicinity of the folded free end 32 of the plate 24. This arrangement of the intermediate lever 28 allows it to pivot, between an unlocked position and a locked position, in a plane parallel to the plane in which the locking lever 22 pivots.

Le dispositif d'actionnement comprend un actionneur antivol 34 dont on a représenté uniquement, et en silhouette, l'extrémité supérieure 36. La commande électrique des déplacements de l'actionneur antivol 34 selon une direction sensiblement parallèle à son axe longitudinal 38 est effectuée par des moyens connus qui ne sont pas représentés et qui ne font pas partie de l'invention. L'extrémité 36 de l'actionneur antivol 34 agit directement sur le levier intermédiaire de secours 28 au moyen d'un pion latéral 40 qui fait saillie hors du plan du levier 28 vers la droite en considérant la figure 1.The actuating device comprises an anti-theft actuator 34 of which the upper end 36 is shown only, and in silhouette, The electrical control of the movements of the anti-theft actuator 34 in a direction substantially parallel to its longitudinal axis 38 is effected by known means which are not shown and which do not form part of the invention. The end 36 of the anti-theft actuator 34 acts directly on the lever emergency intermediary 28 by means of a lateral pin 40 which projects out of the plane of the lever 28 to the right when considering FIG. 1.

La commande de la serrure de portière peut enfin être effectuée au moyen d'un bouton de condam­nation intérieur 42 agencé dans la frise de la por­tière du véhicule automobile. Le bouton de condamna­tion intérieur 42 agit indirectement sur le levier de condamnation 22, par l'intermédiaire du levier de secours 28, auquel il est relié fonctionnellement en un point 44 disposé entre l'axe 30 du levier 28 et le pion latéral 40 sur lequel agit l'actionneur antivol 38. La liaison fonctionnelle entre le bouton de con­damnation intérieur 42 et le levier intermédiaire de secours 28 est représenté, à la figure 1, de manière symbolique par le trait mixte 46.The control of the door lock can finally be performed by means of an interior locking button 42 arranged in the frieze of the door of the motor vehicle. The internal locking button 42 acts indirectly on the locking lever 22, by means of the emergency lever 28, to which it is functionally connected at a point 44 disposed between the axis 30 of the lever 28 and the lateral pin 40 on which the anti-theft actuator 38 acts. The functional connection between the internal locking button 42 and the intermediate emergency lever 28 is represented, in FIG. 1, symbolically by the dashed line 46.

Aux figures 1 et 2, les différents compo­sants du dispositif d'actionnement selon l'invention sont représentés dans la position déverrouillée de la serrure. Dans cette position déverrouillée, le levier de condamnation 22 est en butée contre des moyens de butée correspondants prévus à l'intérieur du boîtier de commande 10. Le levier intermédiaire 28 coopère, au moyen d'une surface de butée 48, constituée par la partie supérieure de son bord , avec une patte d'entraînement 50 du levier de condamnation 22. La patte d'entraînement 50 est formée d'une portion repliée latéralement du levier de condamnation 22. Comme cela sera expliqué plus avant , la patte d'entraînement 50 et la surface de butée 48 consti­tuent des premiers moyens d'entraînement unidirec­tionnel du levier de condamnation 22 vers sa position déverrouillée, par le levier intermédiaire 28.In Figures 1 and 2, the various components of the actuating device according to the invention are shown in the unlocked position of the lock. In this unlocked position, the locking lever 22 is in abutment against corresponding abutment means provided inside the control unit 10. The intermediate lever 28 cooperates, by means of an abutment surface 48, constituted by the part upper edge, with a drive tab 50 of the locking lever 22. The drive tab 50 is formed of a laterally folded portion of the locking lever 22. As will be explained later, the drive tab 50 and the abutment surface 48 constitute first unidirectional drive means for the locking lever 22 towards its unlocked position, by the intermediate lever 28.

La platine fixe 24 comporte également une patte de butée 52 qui s'étend latéralement depuis le plan de la platine 24 et qui a pour fonction de définir de manière précise la position condamnée du levier intermédiaire 28.The fixed plate 24 also includes a stop tab 52 which extends laterally from the plane of the plate 24 and which has the function of precisely defining the locked position of the intermediate lever 28.

Conformément à l'invention, le dispositif d'actionnement comporte également des seconds moyens d'entraînement unidirectionnel du levier de condam­nation 22, vers sa position condamnée, par le levier intermédiaire 28.According to the invention, the actuating device also comprises second unidirectional drive means for the locking lever 22, towards its locked position, by the intermediate lever 28.

Ces seconds moyens d'entraînement comportent un élément élastique 54 agencé sur le levier intermédiaire 28. L'élément élastique 54 est constitué par un ressort en fil comportant deux branches 56 et 58 reliées entre elles par une boucle centrale 60. L'extrémité de la première branche 56 prend appui sous une patte latérale d'accrochage 62 du levier intermé­diaire 28. L'extrémité de la seconde branche 58 du ressort en fil 54 comprend une portion repliée à angle droit 66 qui fait saillie hors du plan du levier intermédiaire 28 pour venir coopérer avec une surface d'entraînement 64 prévue en vis à vis sur le levier de condamnation 22. La surface d'entraînement 64 est formée d'une première portion du bord périphérique du levier de condamnation 22 avec laquelle la portion repliée 66 de l'extrémité de la branche 58 est susceptible de coopérer.These second drive means comprise an elastic element 54 arranged on the intermediate lever 28. The elastic element 54 is constituted by a wire spring comprising two branches 56 and 58 connected together by a central loop 60. The end of the first branch 56 is supported under a lateral hooking tab 62 of the intermediate lever 28. The end of the second branch 58 of the wire spring 54 comprises a portion folded at right angles 66 which projects out of the plane of the intermediate lever 28 for come to cooperate with a driving surface 64 provided opposite on the locking lever 22. The driving surface 64 is formed of a first portion of the peripheral edge of the locking lever 22 with which the folded portion 66 of the the end of the branch 58 is capable of cooperating.

La portion repliée 66 de la branche 58 est reçue dans une lumière oblongue 68 du levier intermé­diaire 28. Du fait de l'action élastique exercée par la boucle centrale 60 du ressort sur la branche 58, la portion repliée 66 est maintenue élastiquement en appui contre le bord extrême de droite, en considérant la figure 2, de la lumière 68. La lumière 68 permet à la branche 58 de pivoter dans le sens horaire, en considérant la figure 2, et d'assurer ainsi la fonc­tion d'escamotage des seconds moyens d'entraînement unidirectionnel comme cela sera exposé plus avant.The folded portion 66 of the branch 58 is received in an oblong opening 68 of the intermediate lever 28. Due to the elastic action exerted by the central loop 60 of the spring on the branch 58, the folded portion 66 is resiliently pressed against the extreme right edge, considering FIG. 2, of the light 68. The light 68 allows the branch 58 to rotate clockwise, considering Figure 2, and thus ensure the retraction function of the second one-way drive means as will be discussed later.

La première portion 64 du bord périphérique du levier 22 se prolonge, selon une direction sensib­lement perpendiculaire, par une seconde portion adja­cente 66 du bord qui définit un profil de came apte à provoquer la déformation élastique de la portion d'extrémité repliée 66 du ressort 54 pour permettre son escamotage.The first portion 64 of the peripheral edge of the lever 22 is extended, in a substantially perpendicular direction, by a second adjacent portion 66 of the edge which defines a cam profile capable of causing the elastic deformation of the folded end portion 66 of the spring 54 to allow its retraction.

On décrira maintenant le mode de réalisation du dispositif d'actionnement selon l'invention.The embodiment of the actuating device according to the invention will now be described.

En partant de la position qu'occupent les divers composants représentés à la figure 2, la phase de condamnation par l'actionneur antivol 34 se déroule de la manière suivante :
- L'actionneur 34 relié au levier intermé­diaire 28 entraîne le mouvement de rotation de celui-­ci dans le sens horaire jusqu'à ce qu'il occupe la position, représentée à la figure 3, dans laquelle la portion repliée 66 du ressort 54 vient en contact avec la surface d'entraînement 64 du levier de condamnation 22.
- Le mouvement de rotation du levier inter­médiaire 28 se poursuit en entraînant en rotation, dans le sens anti-horaire, le levier de condamnation 22 jusqu'à ce que les composants occupent leur position respective représentée à la figure 4.
- Ensuite, comme on peut le constater à la figure 4, la portion repliée 66 du ressort 54 se dégage de la surface d'entraînement 64 et le levier d'entraînement 28 poursuit sa rotation dans le sens horaire, sans entraîner plus avant le levier de condamnation 22, jusqu'à venir en butée contre la patte de butée 52. Toutefois, après ce dégagement de la portion repliée 66 de la surface d'entraînement 64, le levier de condamnation 22 poursuit sa rotation dans le sens anti-horaire, vers sa position condamnée, sous l'action de moyens élastiques internes au boîtier de serrure 10, jusqu'à ce que le levier de condamnation 22 occupe sa position condamnée représentée à la figure 5. Dans cette position, le levier de condamna­tion 22 est en appui contre des moyens de butée, non représentés, internes au boîtier de serrure 10.Starting from the position occupied by the various components shown in FIG. 2, the locking phase by the anti-theft actuator 34 takes place as follows:
- The actuator 34 connected to the intermediate lever 28 causes the rotational movement of the latter in a clockwise direction until it occupies the position, shown in FIG. 3, in which the folded portion 66 of the spring 54 comes in contact with the drive surface 64 of the locking lever 22.
- The rotation movement of the intermediate lever 28 continues by driving in rotation, counterclockwise, the locking lever 22 until the components occupy their respective positions shown in FIG. 4.
- Then, as can be seen in Figure 4, the folded portion 66 of the spring 54 emerges from the drive surface 64 and the drive lever 28 continues to rotate clockwise, without further driving the lever of locking 22, until it abuts against the stop tab 52. However, after this release of the folded portion 66 of the drive surface 64, the locking lever 22 continues to rotate counterclockwise, toward its locked position, under the action of elastic means internal to the lock housing 10, until the locking lever 22 occupies its locked position shown in FIG. 5. In this position, the locking lever 22 is in support against abutment means, not shown, internal to the lock housing 10.

Au cours de cette phase de condamnation, le levier intermédiaire 28 a également entraîné en translation vers le bas le bouton de condamnation intérieur 42 au moyen de la liaison fonctionnelle 46.During this locking phase, the intermediate lever 28 also caused the interior locking button 42 to translate downwards by means of the functional link 46.

Une phase de déverrouillage effectuée au moyen de l'actionneur antivol, en partant de la position représentée à la figure 5, se déroule de la manière suivante :
- L'actionneur antivol 34 entraîne le levier intermédiaire 28 en rotation dans le sens anti-horaire jusqu'à ce que la surface de butée 48 de levier intermédiaire 28 vienne en contact avec la patte d'entraînement 50 du levier de condamnation 22, comme cela est représenté à la figure 6.
- le mouvement de rotation du levier intermédiaire 28 se poursuit dans le sens anti-horaire et provoque, grâce à la coopération entre la surface de butée 48 et la patte d'entraînement 50, la rotation dans le sens horaire du levier de condamnation 22 vers sa position déverrouillée.An unlocking phase carried out by means of the anti-theft actuator, starting from the position shown in FIG. 5, takes place as follows:
- The anti-theft actuator 34 drives the intermediate lever 28 to rotate anti-clockwise until the abutment surface 48 of intermediate lever 28 comes into contact with the drive tab 50 of the locking lever 22, as this is shown in Figure 6.
- The rotation movement of the intermediate lever 28 continues counterclockwise and causes, thanks to the cooperation between the abutment surface 48 and the drive tab 50, the clockwise rotation of the locking lever 22 towards its unlocked position.

La figure 7 représente les positions qu'oc­cupent le levier de condamnation 22 et le levier intermédiaire 28 lorsque la serrure est en position déverrouillée et que le levier de condamnation 22 est en butée contre ses moyens de butée internes au boîtier de serrure 10.FIG. 7 represents the positions occupied by the locking lever 22 and the intermediate lever 28 when the lock is in position unlocked and that the locking lever 22 is in abutment against its abutment means internal to the lock housing 10.

Comme on peut le constater, les deux leviers 22 et 28 sont agencés et dimensionnés de façon à ce que la portion repliée 66 du ressort 54 ne vienne pas interférer avec le profil de came 64 du levier de condamnation 22 lors de cette phase normale de déver­rouillage à l'aide de l'actionneur antivol 34.As can be seen, the two levers 22 and 28 are arranged and dimensioned so that the folded portion 66 of the spring 54 does not come to interfere with the cam profile 64 of the locking lever 22 during this normal unlocking phase using the anti-theft actuator 34.

En cas de panne électrique, il n'est plus possible d'entraîner le levier intermédiaire 28, et donc le levier de condamnation 22, au moyen de l'ac­tionneur antivol 34.In the event of an electrical failure, it is no longer possible to drive the intermediate lever 28, and therefore the locking lever 22, by means of the anti-theft actuator 34.

Pour procéder au déverrouillage de la serrure 10 il est possible d'agir sur le boîtier de serrure au moyen de la clé extérieure 14 pour permet­tre une ouverture de la serrure de porte. Au cours de cette opération manuelle extérieure de déverrouillage de la serrure, le levier de condamnation 22 est en­traîné en rotation, dans le sens horaire, à partir de la position qu'il occupait à la figure 5 pour venir occuper sa position déverrouillée représentée à la figure 8. Lors de cette action manuelle d'ouverture, le levier intermédiaire 28 est resté immobile en butée contre la patte 52 et occupe donc toujours sa position condamnée ainsi que le bouton de condamnation inté­rieur 42.To unlock the lock 10, it is possible to act on the lock housing by means of the external key 14 to allow the door lock to be opened. During this external manual unlocking operation of the lock, the locking lever 22 is rotated, clockwise, from the position it occupied in FIG. 5 to come to occupy its unlocked position shown in FIG. FIG. 8. During this manual opening action, the intermediate lever 28 has remained stationary in abutment against the tab 52 and therefore always occupies its locked position as well as the inner locking button 42.

Après la remise en état de l'actionneur antivol 34, on donne à ce dernier un ordre provoquant son déplacement dans le sens correspondant au déver­rouillage de la serrure qui s'effectue de la manière suivante :
- En partant de la figure 8, le levier intermédiaire 28 commence à tourner dans le sens anti-­ horaire jusqu'à ce que la portion repliée 66 du ressort 54 vienne en contact avec le profil de came 65 du levier de condamnation 22 comme cela est représenté à la figure 9.
- Le levier de condamnation 22 étant en bu­tée en position déverrouillée, la poursuite du mouve­ment de rotation du levier intermédiaire 28, sous l'action de l'actionneur antivol 34, provoque un escamotage progressif de la portion repliée 66 du ressort 54 à l'intérieur de la lumière 68 sous l'effet de came dû au profil de came 65 comme cela est repré­senté à la figure 10.
- Le phénomène d'escamotage de la branche repliée 66 se poursuit jusqu'à ce que les deux leviers occupent leurs positions respectives représentées à la figure 11. Dès que cette position est atteinte, sous l'effet de la sollicitation élastique dûe à la boucle centrale 60, la portion repliée 66 du ressort 54 re­vient brusquement en appui contre le bord extrême de droite de la lumière 68. Le mouvement de rotation du levier intermédiaire 28 se poursuit, comme cela est représenté à la figure 12 jusqu'à ce que la surface de butée 48 vienne en contact avec la patte d'entraînement 50 du levier de condamnation 22 qui définit la position déverrouillée du levier intermé­diaire 28 représenté à la figure 13.After the anti-theft actuator 34 has been repaired, the latter is given an order causing it to move in the direction corresponding to the unlocking of the lock which is carried out as follows:
- Starting from FIG. 8, the intermediate lever 28 begins to rotate in the anti-direction clockwise until the folded portion 66 of the spring 54 comes into contact with the cam profile 65 of the locking lever 22 as shown in FIG. 9.
- The locking lever 22 being in abutment in the unlocked position, the continued rotational movement of the intermediate lever 28, under the action of the anti-theft actuator 34, causes a progressive retraction of the folded portion 66 of the spring 54 at the inside of the light 68 under the cam effect due to the cam profile 65 as shown in FIG. 10.
- The phenomenon of retraction of the folded branch 66 continues until the two levers occupy their respective positions shown in Figure 11. As soon as this position is reached, under the effect of the elastic stress due to the loop central 60, the folded portion 66 of the spring 54 abruptly abuts against the extreme right edge of the light 68. The rotational movement of the intermediate lever 28 continues, as shown in Figure 12 until the abutment surface 48 comes into contact with the drive tab 50 of the locking lever 22 which defines the unlocked position of the intermediate lever 28 shown in FIG. 13.

A l'issue de cette action de "réencliqueta­ge" de la portion élastique 66 du ressort 54 en vis à vis de la surface d'entraînement 64, l'ensemble des composants du dispositif d'actionnement selon l'invention occupe à nouveau leur position déverrouil­lée, également représentée à la figure 3, correspon­dant à un fonctionnement normal du dispositif d'ac­tionnement.At the end of this "reclosing" action of the elastic portion 66 of the spring 54 facing the drive surface 64, all of the components of the actuation device according to the invention again occupy their position unlocked, also shown in Figure 3, corresponding to normal operation of the actuating device.
