Description

La présente invention concerne les serrures pour porte de véhicule automobile et, plus particulièrement, les serrures à condamnation/décondamnation électrique extérieure et/ou intérieure.The present invention relates to locks for motor vehicle and, more particularly, locks with exterior and / or interior electrical locking / unlocking.

De telles serrures comportent, de façon connue, un pêne à fourche destiné à coopérer avec une gâche, un cliquet assurant normalement le blocage du pêne en position fermée, un mécanisme de libération du pêne comportant un organe de commande subissant un mouvement d'actionnement en réponse à l'actionnement, par l'utilisateur, d'une poignée de la porte correspondante du véhicule automobile. L'organe de commande peut prendre une position active pour laquelle il agit, au cours de son mouvement d'actionnement, sur le cliquet pour le mettre dans une position "échappée" ou "effacée" (dans laquelle ledit cliquet libère le pêne), et une position inhibée pour laquelle ledit organe de commande, lors de son mouvement d'actionnement, n'a aucun effet sur ledit cliquet. La serrure comporte, en outre, un dispositif électromécanique de condamnation/décondamnation répondant au moins à un signal de décondamnation en déplaçant ledit organe de commande de sa position inhibée à sa position active.Such locks comprise, in a known manner, a latch fork intended to cooperate with a keeper, a pawl ensuring normally locking the bolt in the closed position, a locking mechanism release of the bolt comprising a control member undergoing a actuation movement in response to actuation, by the user, a handle of the corresponding door of the vehicle automobile. The control unit can take an active position for which it acts, during its actuation movement, on the ratchet to put it in an "escaped" or "erased" position (in which said pawl releases the bolt), and an inhibited position for which said control member, during its movement actuation, has no effect on said pawl. The lock has, in addition, an electromechanical locking / unlocking device responding at least to an unlocking signal by moving said control member from its inhibited position to its active position.

On connaít des systèmes de fermeture de porte de véhicule dans lesquels le signal de décondamnation est généré par l'actionnement d'un barillet de serrure. Dans d'autres systèmes connus, ce signal de décondamnation est fourni par un dispositif électronique de reconnaissance en réponse à un signal de télécommande à infrarouge ou de télécommande radioélectrique produit par l'utilisateur au moyen d'une télécommande appropriée. Avec ces systèmes connus, si la serrure est dans un état condamné, c'est-à-dire si l'organe de commande, qui fait partie du mécanisme de libération du pêne, est dans sa position inhibée, deux actions successives sont alors nécessaires pour ouvrir la porte : tout d'abord, il faut décondamner la serrure à l'aide d'un moyen adapté (clé, télécommande, etc ...), puis il faut ouvrir la porte, par exemple en tirant sur la poignée extérieure de celle-ci.We know vehicle door closing systems in which the unlocking signal is generated by actuation of a lock cylinder. In other known systems, this unlocking signal is provided by an electronic device for recognition in response to an infrared remote control signal or of radio remote control produced by the user by means of a suitable remote control. With these known systems, if the lock is in a condemned state, i.e. if the organ of control, which is part of the bolt release mechanism, is in its position inhibited, two successive actions are then necessary to open the door: first of all, unlock the lock using suitable means (key, remote control, etc.), then open the door, for example by pulling on the outer handle thereof.

Il est évident que, lors d'utilisations fréquentes du véhicule, le fait d'avoir toujours deux actions à faire pour décondamner la serrure et accéder à son véhicule peut apparaítre comme une contrainte. En outre, dans la mesure où ces systèmes connus nécessitent l'utilisation soit d'une clé, soit d'une télécommande, qui occupe une main de l'utilisateur, cela peut apparaítre également comme une gêne.It is obvious that, during frequent uses of the vehicle, always having two actions to unlock the lock and access to your vehicle may appear as a constraint. In addition, insofar as these known systems require the use of either a key or a remote control, which occupies a hand of the user, this can also appear as discomfort.

C'est pourquoi, on a déjà proposé des systèmes dits "d'accès au véhicule main libre" qui sont censés permettre à un utilisateur d'ouvrir directement une porte de son véhicule en une seule action sur la poignée extérieure de la porte correspondante, quel que soit l'état de condamnation ou de décondamnation de la serrure de ladite porte, et cela sans avoir en main une clé, une télécommande ou analogue pour décondamner la serrure. A cet effet, ces systèmes connus sont équipés d'un dispositif électronique de reconnaissance muni d'un émetteur radio et conçu pour pouvoir dialoguer avec un dispositif radioélectrique, appelé "identifiant électronique", incorporé dans une montre, une carte de crédit, un badge ou analogue porté par l'utilisateur. Le dispositif électronique de reconnaissance ne produit son signal de décondamnation qu'après identification du bon propriétaire.This is why, we have already proposed so-called systems "hands-free vehicle access" which is intended to allow a user to directly open a door of his vehicle in one action on the outside handle of the corresponding door, whatever either the state of condemnation or unlocking of the lock of said door, without having a key, remote control or similar to unlock the lock. To this end, these systems known are equipped with an electronic recognition device fitted with a radio transmitter and designed to be able to communicate with a radio device, called "electronic identifier", incorporated in a watch, credit card, badge or the like worn by the user. The electronic recognition device does not produce its unlocking signal only after identification of the correct owner.

Dans de tels systèmes connus, dits à accès main libre, l'émission du signal de décondamnation commandant le dispositif électromécanique de condamnation/décondamnation, d'une part, et l'actionnement du mécanisme de libération, d'autre part, ont lieu simultanément. Or, la différence entre le temps de réponse, relativement long, du dispositif électromécanique et celui, très court, du mécanisme de libération est telle qu'il arrive fréquemment que ledit organe de commande, qui fait partie du mécanisme de libération du pêne, a terminé son mouvement d'actionnement alors qu'il n'a toujours pas été mis en position active par le dispositif électromécanique de condamnation/décondamnation. Il en résulte que la première action de l'utilisateur sur la poignée de la porte n'entraíne pas l'ouverture de cette dernière et que ledit utilisateur doit agir à nouveau sur ladite poignée pour obtenir l'ouverture de la porte. Cette nécessité d'une double action sur la poignée de la porte constitue bien évidemment un inconvénient pour un système qui était censé permettre l'ouverture de la porte en une seule action.In such known systems, known as hands-free systems, the transmission of the unlocking signal controlling the device electromechanical locking / unlocking, on the one hand, and the actuation of the release mechanism, on the other hand, take place simultaneously. Now, the difference between the response time, relatively long, of the electromechanical device and that, very short, of the release mechanism is such that it frequently happens that said control member, which is part of the release mechanism of the bolt, has completed its actuation movement when it still has not put into active position by the electromechanical device of locking / unlocking. As a result, the first action of the user on the door handle does not cause the opening of the latter and that said user must act again on said handle to open the door. This need for double action on the door handle obviously constitutes a disadvantage for a system that was supposed to allow the opening of the door in one action.

La demande de brevet français n° 98 05604 déposée le 4 Mai 1998 fournit deux solutions pour remédier à cet inconvénient. Ces deux solutions consistent à utiliser un moyen de rattrapage d'ouverture qui, lorsqu'il y a émission du signal de décondamnation sensiblement en fin de course du mouvement d'actionnement de l'organe de commande, amène le cliquet dans sa position "échappée". Concrètement, dans ces deux solutions connues, l'organe de commande, qui agit sur le cliquet pour le faire passer dans sa position "échappée" ou un levier d'actionnement, qui fait également partie du mécanisme de libération du pêne, est conformé de manière à présenter une portion de surface en forme de rampe, qui est inclinée par rapport à la direction de mouvement de l'organe de commande et qui, en fin de course du mouvement d'actionnement dudit organe de commande, agit directement ou indirectement, selon la première ou deuxième solution précitée, à la manière d'une came sur le cliquet pour le faire passer dans sa position "échappée".French patent application n ° 98 05604 filed on May 4, 1998 provides two solutions to remedy this drawback. These two solutions consist in using a catch-up means opening which, when the unlocking signal is emitted substantially at the end of the actuation movement of the control member, brings the pawl to its "escaped" position. Concretely, in these two known solutions, the control, which acts on the pawl to move it into its position "breakaway" or an actuation lever, which is also part of the bolt release mechanism, is shaped so as to present a ramp-shaped surface portion, which is inclined relative to to the direction of movement of the control member and which, at the end of stroke of the actuating movement of said control member, acts directly or indirectly, depending on the first or second solution above, like a cam on the pawl to pass it in its "escaped" position.

La présente invention a donc pour but de fournir une solution pour éviter à l'utilisateur d'avoir à exercer une double action sur la poignée de la porte en vue d'ouvrir cette dernière, et cela sans avoir à utiliser un dispositif électrique d'actionnement surpuissant pour décondamner la serrure et faire passer le cliquet dans sa position "échappée".The present invention therefore aims to provide a solution to avoid the user having to exercise a double action on the door handle to open the door, without have to use a powerful electric actuator to unlock the lock and move the ratchet to its position "Escaped".

A cet effet, l'invention fournit une serrure à condamnation/décondamnation électrique pour une porte de véhicule automobile à accès main libre, comprenant :

  • a) un pêne à fourche destiné à coopérer avec une gâche ;
  • b) un cliquet assurant le blocage du pêne en position fermée et pouvant prendre une position "échappée" pour laquelle il n'agit plus sur le pêne ;
  • c) un mécanisme de libération du pêne comportant un organe de commande extérieur qui peut subir un mouvement d'actionnement en réponse à l'actionnement d'une poignée extérieure de ladite porte par un utilisateur et qui, dans un état décondamné vis-à-vis de l'extérieur de la serrure, peut agir, au cours de son mouvement d'actionnement, sur le cliquet pour le mettre dans ladite position "échappée" ;
  • d) un dispositif électromécanique de condamnation/décondamnation incluant un dispositif électrique d'actionnement extérieur réagissant au moins à un signal de condamnation ou décondamnation extérieure pour faire passer la serrure dans ledit état condamné ou décondamné extérieur ;
  • e) un dispositif électronique de reconnaissance apte à produire ledit signal de décondamnation lorsqu'il reçoit un signal de commande approprié, en provenance par exemple d'une télécommande ou d'un dispositif identifiant électronique approprié porté le propriétaire du véhicule ou par un utilisateur autorisé ;
    • caractérisée par le fait qu'elle comprend en outre un dispositif à accumulation d'énergie, qui comporte un moyen à ressort et qui est interposé entre ledit organe de commande et ledit cliquet de telle façon que, dans l'état condamné extérieur de la serrure, ledit moyen à ressort accumule de l'énergie en étant bandé par ledit organe de commande au cours de son mouvement d'actionnement en réponse à l'actionnement de ladite poignée extérieure de porte, et que, lorsque la serrure passe à l'état décondamné vis-à-vis de l'extérieur en réponse audit signal de décondamnation, sensiblement en fin de course du mouvement d'actionnement dudit organe de commande, l'énergie emmagasinée dans ledit moyen à ressort est libérée et le dispositif à accumulation d'énergie fait passer ledit cliquet dans sa position "échappée".To this end, the invention provides an electric locking / unlocking lock for a door of a motor vehicle with hands-free access, comprising:
  • a) a fork bolt intended to cooperate with a keeper;
  • b) a pawl ensuring the locking of the bolt in the closed position and which can take an "escaped" position for which it no longer acts on the bolt;
  • c) a bolt release mechanism comprising an external control member which can undergo an actuating movement in response to the actuation of an external handle of said door by a user and which, in a unlocked state with respect to screw from the outside of the lock, can act, during its actuation movement, on the pawl to put it in said "escaped"position;
  • d) an electromechanical locking / unlocking device including an electrical external actuation device reacting at least to an external locking or unlocking signal to move the lock into said exterior locked or unlocked state;
  • e) an electronic recognition device capable of producing said unlocking signal when it receives an appropriate control signal, coming for example from a remote control or from an appropriate electronic identifying device worn by the owner of the vehicle or by an authorized user ;
    • characterized in that it further comprises an energy storage device, which comprises a spring means and which is interposed between said control member and said pawl in such a way that, in the external locked state of the lock , said spring means accumulates energy by being bandaged by said control member during its actuation movement in response to the actuation of said exterior door handle, and that, when the lock changes to the state unlocked from the outside in response to said unlocking signal, substantially at the end of the movement of actuation of said control member, the energy stored in said spring means is released and the accumulation device energy causes said pawl to pass into its "escaped" position.

    Dans ces conditions, lorsque le dispositif électronique de reconnaissance identifie le bon propriétaire ou un utilisateur autorisé et que ce dernier tire la poignée de porte, le cliquet est automatiquement amené dans sa position "échappée" et le pêne libéré, grâce à l'énergie "gratuite" accumulée dans le moyen à ressort lors de l'actionnement de la poignée de porte. Il en résulte que le dispositif électrique d'entraínement, prévu pour la condamnation/décondamnation de la serrure et constitué par exemple par un électro-aimant ou par un moteur électrique, peut avoir une taille et une puissance réduites puisqu'il ne sert plus à faire passer le cliquet dans sa position "échappée" pour libérer le pêne, mais seulement à décondamner la serrure.Under these conditions, when the electronic device of recognition identifies the correct owner or an authorized user and that the latter pulls the door handle, the pawl is automatically brought into its "escaped" position and the bolt released, thanks to the energy "free" accumulated in the spring means upon actuation of the door handle. As a result, the electrical device training, planned for the conviction / unlocking of the lock and constituted for example by an electromagnet or by a electric motor, may have reduced size and power since it is no longer used to move the pawl into its position "escape" to release the bolt, but only to unlock the lock.

    Dans un mode de réalisation de la présente invention, ledit dispositif à accumulation d'énergie comporte un premier levier basculant qui est attaché audit organe de commande et bascule autour d'un premier axe sous l'action dudit organe de commande, un deuxième levier basculant qui est monté basculant sur ledit premier axe et qui coopère avec le cliquet de manière à l'entraíner avec lui dans son mouvement de basculement, et ledit moyen à ressort qui est monté entre les deux leviers basculants.In one embodiment of the present invention, said energy storage device has a first lever which is attached to said control member and swings around of a first axis under the action of said control member, a second tilting lever which is pivotally mounted on said first axis and who cooperates with the ratchet so as to drag him with him in his tilting movement, and said spring means which is mounted between the two tilting levers.

    Dans l'état décondamné extérieur de la serrure, le dispositif électro-mécanique de condamnation/décondamnation accouple les premier et deuxième leviers basculants de telle sorte qu'ils basculent conjointement autour dudit premier axe sous l'action dudit organe de commande. Dans l'état condamné extérieur de la serrure, ledit dispositif électromécanique de condamnation/décondamnation empêche le deuxième levier de basculer, de sorte que le moyen à ressort soit bandé par le premier levier lorsqu'il bascule sous l'action dudit organe de commande.In the unlocked outside state of the lock, the electro-mechanical coupling / unlocking device the first and second rocking levers so that they rock jointly around said first axis under the action of said organ of ordered. In the locked external state of the lock, said electromechanical locking / unlocking device prevents the second lever to tilt, so that the spring is bandaged by the first lever when it rocks under the action of said organ control.

    Dans un mode de réalisation de l'invention, le deuxième levier basculant peut présenter des première et seconde pattes, qui sont espacées l'une de l'autre dans une direction tangentielle par rapport au mouvement de basculement dudit deuxième levier et qui font saillie sur une face de ce deuxième levier à distance dudit premier axe. Le deuxième levier présente également une première lumière oblongue qui s'étend dans le sens longitudinal du deuxième levier, entre ledit premier axe et les première et seconde pattes.In one embodiment of the invention, the second tilting lever may have first and second legs, which are spaced from each other in a tangential direction from the tilting movement of said second lever and which protrude from one face of this second lever at a distance from said first axis. The second lever also has a first oblong lumen which extends in the longitudinal direction of the second lever, between said first axis and first and second legs.

    Dans ce mode de réalisation, le premier levier basculant passe entre les première et seconde pattes du deuxième levier basculant et présente une troisième patte qui fait saillie sur une face de ce premier levier à distance dudit premier axe et qui est en appui sur la première patte du deuxième levier en absence d'action sur la poignée de porte. Le premier levier basculant présente également une seconde lumière ayant deux parties sensiblement en L, dont l'une des deux parties coïncide avec la première lumière oblongue du deuxième levier quand ladite troisième patte est en appui sur ladite première patte. Ledit moyen à ressort peut être alors disposé entre lesdites seconde et troisième pattes, et il peut être constitué par un ressort hélicoïdal.In this embodiment, the first tilting lever passes between the first and second legs of the second rocking lever and has a third tab which projects from one side of this first lever remote from said first axis and which is supported on the first second lever tab in the absence of action on the door handle. The first tilting lever also has a second light having two substantially L-shaped parts, one of the two parts coincides with the first oblong light of the second lever when said third leg is supported on said first leg. said spring means can then be disposed between said seconds and third legs, and it can be constituted by a helical spring.

    Le dispositif électromécanique de condamnation/ décondamnation peut comporter un levier de condamnation extérieure qui est couplé au dispositif électrique d'actionnement extérieur et qui est monté pivotant sur un second axe qui est parallèle audit premier axe. Dans ce cas, le levier de condamnation extérieure peut présenter un doigt de blocage qui, dans l'état condamné extérieur de la serrure, coopère avec la seconde patte du deuxième levier basculant pour empêcher celui-ci de basculer. De préférence, dans l'état condamné extérieur de la serrure, lesdites première et seconde pattes du deuxième levier basculant, ledit doigt de blocage et le centre dudit second axe sont alignés.The electromechanical locking device / unlocking may include an external locking lever which is coupled to the external electrical actuation device and which is pivotally mounted on a second axis which is parallel to said first axis. In this case, the external locking lever may have a locking finger which, in the locked external condition of the lock, cooperates with the second leg of the second rocking lever for prevent it from tipping over. Preferably in the condemned state outside of the lock, said first and second legs of the second tilting lever, said locking finger and the center of said second axis are aligned.

    Le dispositif électromécanique de condamnation/ décondamnation peut en outre comporter une biellette, dont une première extrémité est accouplée aux premier et deuxième leviers basculants par un premier téton qui est engagé dans les première et seconde lumières desdits premier et deuxième leviers basculants et qui les rend solidaires en rotation l'un de l'autre dans l'état décondamné extérieur de la serrure. La seconde extrémité de la biellette est accouplée audit levier de condamnation par un second téton qui est engagé dans une troisième lumière oblongue prévue dans ce levier de condamnation. Cette troisième lumière est, au moins approximativement, alignée avec la première lumière oblongue du deuxième levier basculant dans l'état décondamné extérieur de la serrure. Le second téton est mobile dans la troisième lumière à l'encontre de la force de rappel d'un ressort qui sollicite la biellette dans un sens tel que son premier téton tend à venir se placer à celle des deux extrémités de ladite première lumière oblongue qui est la plus éloignée dudit premier axe.The electromechanical locking device / unlocking may also include a link, one of which first end is coupled to the first and second levers tilting by a first stud which is engaged in the first and second lights of said first and second tilting levers and which makes them integral in rotation with each other in the unlocked state outside of the lock. The second end of the link is coupled to said locking lever by a second stud which is engaged in a third oblong light provided in this lever conviction. This third light is, at least approximately, aligned with the first oblong light of the second lever tilting in the external unlocked state of the lock. The second stud is movable in the third light at against the return force of a spring which urges the link in a direction such that its first nipple tends to come to be placed with that of two ends of said first oblong lumen which is the most distant from said first axis.

    Avantageusement, le dispositif électromécanique de condamnation/décondamnation comprend un dispositif électrique d'actionnement intérieur réagissant à un signal de décondamnation intérieure pour faire passer la serrure dans un état décondamné intérieur, dans laquelle l'actionnement d'une poignée intérieure de porte par un utilisateur agit sur le mécanisme de libération du pêne, pour mettre le cliquet en position échappée, et à un signal de condamnation intérieure, pour faire passer la serrure dans un état condamné intérieur, dans lequel l'actionnement de la poignée intérieure de porte et la tirette de frise sont sans effet sur ledit mécanisme de libération, ledit dispositif électromécanique de condamnation/ décondamnation comprenant un levier de condamnation intérieure qui est couplé audit dispositif électrique d'actionnement intérieur, ledit levier de condamnation intérieure étant monté pivotant sur un axe et présentant une première ouverture oblongue sensiblement en arc de cercle, traversée par un pion d'entraínement qui est reçu également dans une deuxième ouverture oblongue, s'étendant sensiblement perpendiculairement à la première ouverture oblongue, dans le levier de condamnation extérieure, de façon que le pivotement de l'un desdits levier de condamnation intérieure et levier de condamnation extérieure provoque le libre coulissement du pion d'entraínement dans l'ouverture oblongue de l'autre desdits levier de condamnation intérieure et levier de condamnation extérieure.Advantageously, the electromechanical device of locking / unlocking includes an electrical device internal actuation reacting to a unlocking signal inside to put the lock in an unlocked state interior, in which the actuation of an interior handle of carried by a user acts on the bolt release mechanism, to put the pawl in the escaped position, and at a signal inner lock, to get the lock into a state inner condemned, in which the actuation of the inner handle door and the frieze zipper have no effect on the said release, said electromechanical locking device / unlocking including an inner locking lever which is coupled to said electric internal actuation device, said inner locking lever being pivotally mounted on an axis and having a first oblong opening substantially in an arc of circle, crossed by a training piece which is also received in a second oblong opening, extending substantially perpendicular to the first oblong opening, in the lever of external condemnation, so that the pivoting of one of said interior locking lever and exterior locking lever causes free movement of the drive pin in the opening oblong from the other of said interior locking lever and lever of external condemnation.

    Dans un mode de réalisation particulier, la serrure comporte un levier supplémentaire pour la décondamnation extérieure automatique à l'ouverture intérieure, ledit levier supplémentaire étant monté pivotant sur ledit second axe et comportant une première branche apte à coopérer avec la poignée intérieure de porte, ledit levier supplémentaire coopérant avec le levier de condamnation extérieure pour le faire pivoter vers sa position décondamnée extérieure, lors de l'actionnement de la poignée intérieure de porte. Dans ce cas, ledit levier supplémentaire peut comporter une deuxième branche apte à coopérer avec une tirette de frise intérieure, pour faire pivoter le levier de condamnation extérieure vers sa position condamnée extérieure, lors de l'actionnement de la tirette de frise vers sa position condamnée extérieure.In a particular embodiment, the lock has an additional lever for external unlocking automatic upon internal opening, said additional lever being pivotally mounted on said second axis and comprising a first branch able to cooperate with the interior door handle, said lever additional cooperating with the external locking lever to rotate it to its outer unlocked position, when actuation of the interior door handle. In this case, said additional lever may include a second branch capable of cooperate with an interior frieze zipper, to rotate the lever external condemnation to its external condemned position, when of the actuation of the frieze zipper towards its locked position exterior.

    Selon une autre caractéristique, le levier supplémentaire et le levier de condamnation extérieure sont couplés en rotation dans la position décondamnée intérieure et sont découplés en rotation en position condamnée intérieure. Dans ce cas, le levier supplémentaire peut comporter une troisième ouverture sensiblement en L dont une première partie correspond à ladite deuxième ouverture oblongue du levier de condamnation extérieure et dont une deuxième partie correspond à la première ouverture oblongue du levier de condamnation intérieure, en position condamnée intérieure, ladite troisième ouverture étant traversée par le pion d'entraínement précité. De préférence, le levier supplémentaire est intercalé entre le levier de condamnation intérieure et le levier de condamnation extérieure. Avantageusement, le dispositif électromécanique de condamnation/ décondamnation est apte à réagir à un signal de décondamnation pour faire passer la serrure d'un état supercondamné à un état décondamné vis-à-vis de l'intérieur et de l'extérieur.According to another characteristic, the additional lever and the external locking lever are coupled in rotation in the inner unlocked position and are decoupled in rotation in interior condemned position. In this case, the additional lever may include a third substantially L-shaped opening, one of which first part corresponds to said second oblong opening of the external locking lever and a second part of which corresponds to the first oblong opening of the lever inner lock, in the inner locked position, said third opening being crossed by the aforementioned drive pin. Preferably, the additional lever is interposed between the lever inner lock and the outer lock lever. Advantageously, the electromechanical locking device / unlocking is able to react to an unlocking signal for change the lock from a super-locked state to a unlocked state vis-à-vis the interior and exterior.

    L'alimentation en courant électrique du dispositif électrique d'actionnement peut être obtenue par un commutateur normalement ouvert, dont la fermeture est commandée en réponse à l'émission du signal de décondamnation, ce commutateur fermant un circuit d'alimentation électrique du dispositif électrique d'actionnement.The power supply of the device electric actuation can be obtained by a switch normally open, closing of which is ordered in response to the transmission of the unlocking signal, this switch closing a electrical supply circuit of the electrical actuating device.

    De préférence, le dispositif électronique de reconnaissance n'est alimenté électriquement que lors de l'action d'ouverture exercée sur la poignée de porte par l'utilisateur. On évite ainsi que le dispositif électronique de reconnaissance ne soit alimenté en permanence et consomme inutilement de l'énergie.Preferably, the electronic recognition device is electrically powered only during the opening action exerted on the door handle by the user. This prevents the device recognition electronics is permanently powered and consumes energy unnecessarily.

    A cet effet, l'alimentation en courant électrique du dispositif électronique de reconnaissance peut être obtenue par un système de commande, tel qu'un micro-interrupteur, normalement ouvert, dont la fermeture est commandée par ladite action d'ouverture exercée sur la poignée de porte, ce micro-interrupteur fermant un circuit d'alimentation électrique du dispositif électronique de reconnaissance.To this end, the supply of electric current to the electronic recognition device can be obtained by a control system, such as a microswitch, normally open, the closing of which is controlled by said opening action exerted on the door handle, this microswitch closing a electrical supply circuit of the electronic device recognition.

    En se référant à la figure 1, on peut voir que le premier mode de réalisation de la serrure selon l'invention comporte un pêne à fourche 1, dont la fourche délimite un logement 2, sensiblement en forme de V, qui est destiné à recevoir une gâche 3 qui coopère avec la serrure. De façon connue, la gâche 3 peut être constituée par un téton qui fait saillie sur un montant fixe d'une porte d'un véhicule automobile en vis-à-vis de la serrure qui est portée par ladite porte. Le mouvement relatif de la porte par rapport au montant de porte, dans le sens de la fermeture de la porte, correspond à un déplacement relatif de la gâche 3 selon la flèche F1 de la figure 1.Referring to Figure 1, we can see that the first embodiment of the lock according to the invention comprises a latch fork 1, the fork of which delimits a housing 2, substantially in V shape, which is intended to receive a keeper 3 which cooperates with the lock. In a known manner, the keeper 3 can be constituted by a stud which protrudes from a fixed amount of a door of a motor vehicle opposite the lock which is carried by said door. Movement relative of the door with respect to the door jamb, in the direction of the door closing, corresponds to a relative movement of the striker 3 according to arrow F1 in FIG. 1.

    Le pêne 1 est susceptible de pivoter autour d'un axe 4 et, dans l'état fermé de la serrure, il coopère avec un cliquet 5, qui peut pivoter autour d'un axe 6. Le cliquet 5 est soumis à une force de rappel élastique qui le pousse vers le pêne 1. Cette force de rappel élastique peut être produite par un ressort (non montré), par exemple un ressort de torsion porté par l'axe 6.The bolt 1 is capable of pivoting about an axis 4 and, in the closed state of the lock, it cooperates with a pawl 5, which can pivot around an axis 6. The pawl 5 is subjected to a restoring force elastic which pushes it towards the bolt 1. This elastic return force can be produced by a spring (not shown), for example a spring of torsion carried by the axis 6.

    Lorsque, à la fermeture de la porte, le pêne 1 est repoussé à l'encontre d'une force de rappel élastique qui agit sur lui, dans la position où il se trouve sur la figure 1, le cliquet 5 vient prendre appui par son bec 5a contre un cran 1a formé sur le pêne 1. De la sorte, le pêne 1 est retenu dans la position qu'il occupe sur la figure 1 et la gâche 3 est emprisonnée dans l'évidement 2, ce qui maintient la porte en état de fermeture.When, when the door is closed, the bolt 1 is pushed back against an elastic restoring force which acts on it, in the position in which it is located in FIG. 1, the pawl 5 comes to bear by its beak 5 has against a notch 1 has formed on the bolt 1. In this way, the bolt 1 is retained in the position it occupies in FIG. 1 and the keeper 3 is trapped in the recess 2, which maintains the door in closed state.

    De façon connue, le pêne 1 peut comporter un deuxième cran 1b, qui correspond à une position légèrement ouverte, mais verrouillée, de la porte, lorsque ce cran coopère avec le bec 5a du cliquet 5.In known manner, the bolt 1 may comprise a second notch 1b, which corresponds to a slightly open, but the locked position, the door, when this notch cooperates with the spout 5 has the pawl 5.

    La serrure comporte en outre un mécanisme de libération qui, dans certaines conditions qui seront décrites plus loin, permet de libérer le pêne 1 en faisant passer le cliquet 5 dans une position "échappée" ou "effacée" pour laquelle il ne bloque plus le pêne 1 et permet donc l'ouverture de la porte. Ce mécanisme, qui n'est que partiellement représenté dans la figure 1, comporte, de façon connue, un organe de commande 7, qui est relié mécaniquement à la poignée de porte (non montrée) de façon à pouvoir être actionné par cette poignée lorsque l'utilisateur exerce une traction sur elle, plus précisément sur une palette mobile de ladite poignée.The lock further includes a release mechanism which, under certain conditions which will be described later, makes it possible to release the bolt 1 by passing the pawl 5 into a position "escaped" or "erased" for which it no longer blocks the bolt 1 and therefore allows the door to be opened. This mechanism, which is only partially shown in FIG. 1, comprises, in a known manner, a control member 7, which is mechanically connected to the handle door (not shown) so that it can be operated by this handle when the user pulls on it, more precisely on a movable pallet of said handle.

    Dans l'exemple de réalisation représenté sur la figure 1, l'organe de commande 7 est constitué par une tringle, dont l'extrémité supérieure est attachée à un levier basculant 8 qui peut basculer autour d'un axe 9 sous l'action de la tringle de commande 7. Dans la figure 1, la flèche F2 indique le sens de déplacement de la tringle de commande 7 lorsque l'utilisateur exerce une traction sur la poignée de porte.In the embodiment shown in FIG. 1, the control member 7 is constituted by a rod, the end of which upper is attached to a rocker lever 8 which can rock around an axis 9 under the action of the control rod 7. In FIG. 1, arrow F2 indicates the direction of movement of the control rod 7 when the user exerts traction on the door handle.

    Un deuxième levier 11 est monté basculant sur l'axe 9 et est couplé au cliquet 5 de manière à l'entraíner avec lui dans son mouvement de basculement. Dans le mode de réalisation le plus simple, les deux axes 6 et 9 peuvent être par exemple confondus ou alignés l'un avec l'autre. Dans ce cas, le cliquet 5 et le levier 11 peuvent être réalisés d'une seule pièce ou sous la forme de deux pièces distinctes qui sont accolées l'une à l'autre lors de l'assemblage des pièces de la serrure et qui sont pourvues d'éléments complémentaires (par exemple un tenon et une mortaise) qui sont emboítés l'un dans l'autre lors dudit assemblage de ces deux pièces afin de les rendre solidaires en rotation. Dans un autre mode de réalisation de l'invention, les deux axes 6 et 9 peuvent être séparés et disposés parallèlement l'un à l'autre et le levier 11 peut agir sur le cliquet 5 soit directement, par exemple par poussée, soit par l'intermédiaire d'un moyen de transmission de mouvement, comme par exemple une biellette de liaison formant un parallélogramme articulé avec le cliquet 5 et le levier 11, ou encore un jeu d'engrenages porté par les axes 6 et 9.A second lever 11 is mounted tilting on the axis 9 and is coupled to the pawl 5 so as to drive it with it in its tilting movement. In the most preferred embodiment simple, the two axes 6 and 9 can for example be combined or aligned with each other. In this case, the pawl 5 and the lever 11 can be made in one piece or as two pieces separate which are joined to each other during the assembly of parts of the lock which are provided with complementary elements (for example a tenon and a mortise) which are fitted one in the other during said assembly of these two parts in order to make them united in rotation. In another embodiment of the invention, the two axes 6 and 9 can be separated and arranged in parallel one to the other and the lever 11 can act on the pawl 5 either directly, by example by pushing, either through a means of transmission of movement, such as a connecting rod link forming a hinged parallelogram with the pawl 5 and the lever 11, or a set of gears carried by axes 6 and 9.

    Le levier 11 présente, en saillie sur une de ses faces et à distance de l'axe 9, deux pattes 11a, 11b qui sont espacées l'une de l'autre dans une direction tangentielle par rapport au mouvement de basculement de ce levier 11 autour de l'axe 9. Le levier 11 comporte en outre une lumière oblongue 12 qui s'étend en gros dans le sens longitudinal dudit levier 11, entre l'axe 9 et la paire de pattes 11a, 11b.The lever 11 has, projecting on one of its faces and at a distance from the axis 9, two legs 11 a , 11 b which are spaced from one another in a tangential direction relative to the tilting movement of this lever 11 around the axis 9. The lever 11 further comprises an oblong slot 12 which extends roughly in the longitudinal direction of said lever 11, between the axis 9 and the pair of lugs 11 a , 11 b .

    Comme montré dans les figures, le levier 8 passe entre les deux pattes 11a et 11b du levier 11 et il présente lui-même une patte 8a qui fait saillie sur une de ses faces à distance de l'axe 9 et qui, en l'absence de toute action sur la poignée de porte, est maintenue en appui contre la patte 11a du levier 11 par un moyen à ressort 13, par exemple un ressort hélicoïdal. L'extrémité opposée du ressort 13 prend appui sur la patte 11b du levier 11. Le levier 8 comporte également une lumière 14 ayant deux parties 14a et 14b disposées en équerre. La partie 14a de la lumière 14 coïncide avec la lumière oblongue 12 du levier 11 quand la patte 8a est en appui sur la patte 11a, comme montré dans les figures 1 et 2.As shown in the figures, the lever 8 passes between the two tabs 11 a and 11 b of the lever 11 and it itself has a tab 8 a which projects on one of its faces at a distance from the axis 9 and which, in the absence of any action on the door handle, is held pressed against the lug 11a of the lever 11 by a spring means 13, for example a helical spring. The opposite end of the spring 13 bears on the tab 11 b of the lever 11. The lever 8 also includes a slot 14 having two parts 14 a and 14 b arranged at right angles. The part 14 has light 14 coincides with the oblong light 12 of the lever 11 when the tab 8 a is in contact with the tab 11 a , as shown in FIGS. 1 and 2.

    Comme cela sera expliqué en détail plus loin au cours de la description du fonctionnement de la serrure, les deux leviers 8 et 11 et le ressort 13 constituent ensemble un dispositif à accumulation d'énergie qui accouple la tringle de commande 7 au cliquet 5.As will be explained in detail later in the course of the description of the operation of the lock, the two levers 8 and 11 and the spring 13 together constitute an accumulation device of energy which couples the control rod 7 to the pawl 5.

    La serrure selon l'invention comporte en outre, de façon connue, un dispositif électromécanique de condamnation/décondamnation 15 comportant un dispositif électrique d'actionnement 16 qui permet de mettre la serrure de manière sélective soit dans un état condamné, soit dans un état décondamné. Ce dispositif électrique d'actionnement 16 peut être constitué, de façon connue en soi, par exemple par un électro-aimant qui est couplé, par exemple par une tringle de liaison 17, à un levier de condamnation 18, qui peut pivoter sur un axe 19. Ainsi, le levier 18 peut être placé sélectivement soit dans la position représentée dans la figure 1, qui correspond à l'état décondamné de la serrure, soit dans la position représentée dans la figure 2, qui correspond à l'état condamné de la serrure.The lock according to the invention further comprises, so known, an electromechanical device for locking / unlocking 15 comprising an electrical actuating device 16 which allows to selectively put the lock either in a state condemned, either in a unlocked state. This electrical device actuator 16 can be constituted, in a manner known per se, by example by an electromagnet which is coupled, for example by a connecting rod 17, to a locking lever 18, which can pivot on an axis 19. Thus, the lever 18 can be selectively placed either in the position shown in Figure 1, which corresponds to the state unlocked from the lock, either in the position shown in the Figure 2, which corresponds to the locked state of the lock.

    Dans l'état condamné de la serrure, un doigt de blocage 18a du levier 18 se trouve en vis-à-vis de la patte 11b du levier 11 et empêche celui-ci de basculer autour de l'axe 9. La patte 11b du levier 11, le doigt de blocage 18a et le centre de l'axe 19 sont de préférence alignés de façon à procurer un appui rigide au levier 11 dans l'état condamné de la serrure, si une personne non autorisée exerce une traction sur la poignée de porte. Dans ces conditions, l'actionnement de la tringle de commande 7 en réponse à l'actionnement de la poignée de porte n'a aucun effet sur le cliquet 5 et la serrure reste verrouillée, de sorte que la porte ne peut être ouverte.In the locked state of the lock, a blocking finger 18 a of the lever 18 is located opposite the tab 11 b of the lever 11 and prevents the latter from tilting around the axis 9. The tab 11 b of the lever 11, the locking finger 18 a and the center of the axis 19 are preferably aligned so as to provide rigid support for the lever 11 in the locked state of the lock, if an unauthorized person exercises a pull on the door handle. Under these conditions, the actuation of the control rod 7 in response to the actuation of the door handle has no effect on the pawl 5 and the lock remains locked, so that the door cannot be opened.

    Le dispositif électromécanique de condamnation/ décondamnation 15 comporte en outre une biellette 21 dont les extrémités sont respectivement munies de tétons 22 et 23. L'une des extrémités de la biellette 21 est accouplée aux leviers 8 et 11 par le téton 22 qui est engagé dans les lumières 12 et 14 desdits leviers. Dans l'état décondamné de la serrure (figure 1), le téton 22 se trouve à l'extrémité de la lumière 12 du levier 11 et à l'extrémité correspondante de la partie 14a de la lumière 14 du levier 8, qui sont les plus éloignées de l'axe 9. Dans cette position, le téton 22 de la biellette 21 accouple les deux leviers 8 et 11 de telle façon qu'ils puissent basculer ensemble autour de l'axe 9 sous l'action de la tringle de commande 7.The electromechanical locking / unlocking device 15 further comprises a link 21 whose ends are respectively provided with studs 22 and 23. One end of the link 21 is coupled to levers 8 and 11 by the stud 22 which is engaged in lights 12 and 14 of said levers. In the unlocked state of the lock (FIG. 1), the stud 22 is located at the end of the lumen 12 of the lever 11 and at the corresponding end of the part 14 a of the lumen 14 of the lever 8, which are furthest from the axis 9. In this position, the stud 22 of the link 21 couples the two levers 8 and 11 so that they can tilt together around the axis 9 under the action of the rod command 7.

    Dans l'état condamné de la serrure (figure 2), le téton 22 de la biellette 21 se trouve à l'extrémité de la lumière 12 la plus proche de l'axe 9. Dans cette position, les deux leviers 8 et 11 sont désaccouplés. En effet, si le levier 8 est basculé autour de l'axe 9 par la tringle de commande 7 en réponse à l'actionnement de la poignée de porte, le téton 22 s'engage dans la partie 14b de la lumière 14, de sorte que le levier 11 n'est pas entraíné avec le levier 8. Bien entendu, l'amplitude totale du mouvement de basculement du levier 8 autour de l'axe 9, correspondant à la course totale de mouvement de la tringle de commande 7 en réponse à l'actionnement de la poignée de porte, doit être telle que le téton 22 de la biellette 21 ne vienne jamais en contact avec l'extrémité de la partie 14b de la lumière 14 et que le levier 8 ne vienne jamais en contact avec la patte 11b du levier 11.In the locked state of the lock (Figure 2), the stud 22 of the link 21 is located at the end of the slot 12 closest to the axis 9. In this position, the two levers 8 and 11 are uncoupled. Indeed, if the lever 8 is tilted around the axis 9 by the control rod 7 in response to the actuation of the door handle, the stud 22 engages in the part 14 b of the light 14, of so that the lever 11 is not driven with the lever 8. Of course, the total amplitude of the tilting movement of the lever 8 around the axis 9, corresponding to the total stroke of movement of the control rod 7 in response to the actuation of the door handle, must be such that the stud 22 of the link 21 never comes into contact with the end of the part 14 b of the light 14 and that the lever 8 never comes into contact with the tab 11 b of the lever 11.

    L'autre extrémité de la biellette 21 est accouplée au levier de condamnation 18 par le téton 23 qui est engagé dans une lumière oblongue 24 du levier 18. Comme montré dans la figure 1, la lumière oblongue 24 est au moins approximativement alignée avec la lumière oblongue 12 du levier 11 et également avec la partie 14a de la lumière 14 du levier 8, dans l'état décondamné de la serrure. Le téton 23 de la biellette 21 est mobile dans la lumière 24 à l'encontre de la force de rappel d'un ressort 25 qui sollicite la biellette dans un sens tel que son téton 22 tend à venir se placer à l'extrémité de la lumière 12 qui est la plus éloignée de l'axe 9.The other end of the link 21 is coupled to the locking lever 18 by the stud 23 which is engaged in an oblong opening 24 of the lever 18. As shown in FIG. 1, the oblong opening 24 is at least approximately aligned with the opening oblong 12 of lever 11 and also with part 14 a of light 14 of lever 8, in the unlocked state of the lock. The stud 23 of the link 21 is movable in the light 24 against the return force of a spring 25 which biases the link in a direction such that its stud 22 tends to come to be placed at the end of the light 12 which is furthest from axis 9.

    Afin de permettre un accès main libre au véhicule, c'est-à-dire afin de permettre à l'utilisateur d'ouvrir la porte de son véhicule par une action unique sur la poignée de porte, sans que l'utilisateur ait à employer une clé ou une télécommande pour décondamner au préalable la serrure si elle était dans un état condamné, un dispositif électronique de reconnaissance 26 (figure 1) est associé à la serrure pour la faire passer dans un état décondamné lorsqu'il reconnaít un dispositif identifiant électronique approprié 27 porté par le propriétaire du véhicule ou par un utilisateur autorisé. Ce dispositif électronique de reconnaissance 26 comporte, de façon connue, un émetteur radio équipé d'une antenne 28, qui peut être par exemple logée dans la poignée de porte et au moyen de laquelle il peut dialoguer, selon un protocole approprié prédéfini, avec un dispositif radioélectrique, également équipé d'une antenne 29, du dispositif identifiant électronique 27. Ce dispositif 27 peut être incorporé, de façon connue, dans une montre ou une carte ou un badge porté par l'utilisateur.In order to allow hands-free access to the vehicle, i.e. to allow the user to open the door of their vehicle by a single action on the door handle, without the user having use a key or remote control to unlock the the lock if it was in a condemned state, a device recognition electronics 26 (figure 1) is associated with the lock to put it in an unlocked state when it recognizes a appropriate electronic identification device 27 worn by the owner vehicle or by an authorized user. This electronic device recognition 26 comprises, in known manner, a radio transmitter equipped with an antenna 28, which can for example be housed in the door handle and by means of which it can interact, according to a appropriate predefined protocol, with a radio device, also equipped with an antenna 29, with the device identifying electronic device 27. This device 27 can be incorporated, in a known manner, in a watch or card or badge worn by the user.

    Lorsque le dispositif électronique de reconnaissance 26 reconnaít le bon propriétaire ou un utilisateur autorisé, il émet sur sa sortie un signal de décondamnation qui est envoyé par la ligne 31 au dispositif électromécanique de condamnation/décondamnation 15 décrit plus haut, en vue de décondamner la serrure. Par exemple, dans le mode de réalisation représenté sur la figure 1, en réponse au signal de décondamnation présent sur la ligne 31, un commutateur 32 se ferme et établit ainsi un circuit d'alimentation du dispositif électrique d'actionnement 16, par exemple un électro-aimant, à partir d'une source de tension Vc1.When the electronic recognition device 26 recognizes the correct owner or an authorized user, it transmits on its an unlocking signal which is sent by line 31 to the electromechanical locking / unlocking device 15 described above, in order to unlock the lock. For example, in the embodiment shown in Figure 1, in response to the signal unlocking present on line 31, a switch 32 closes and thus establishes a supply circuit for the electrical device actuator 16, for example an electromagnet, from a voltage source Vc1.

    Usuellement, l'émission du signal de décondamnation qui commande le dispositif électrique d'actionnement 16, d'une part, et l'actionnement du mécanisme de libération du pêne, c'est-à-dire l'actionnement de la poignée de porte et, par suite, l'actionnement de la tringle de commande 7, d'autre part, ont lieu simultanément ou à peu près simultanément. Cela est particulièrement vrai lorsque, afin d'éviter une consommation inutile d'énergie électrique, le dispositif électronique de reconnaissance 26 n'est alimenté en courant électrique que lors de l'action exercée sur la poignée de porte par l'utilisateur pour ouvrir la porte. A cet effet, comme montré dans la figure 1, le dispositif électronique de reconnaissance 26 est relié électriquement à une source de tension continue Vc2 par exemple par un micro-interrupteur 33, qui est normalement ouvert et peut être fermé en réponse à ladite action sur la poignée de porte, comme cela est symbolisé par la flèche 34.Usually, the emission of the unlocking signal which controls the electrical actuation device 16, on the one hand, and actuation of the bolt release mechanism, i.e. actuation of the door handle and, consequently, actuation of the control rod 7, on the other hand, take place simultaneously or more or less close simultaneously. This is especially true when, in order avoid unnecessary consumption of electrical energy, the device recognition electronics 26 is not supplied with electric current that during the action exerted on the door handle by the user to open the door. To this end, as shown in Figure 1, the electronic recognition device 26 is electrically connected to a DC voltage source Vc2 for example by a microswitch 33, which is normally open and can be closed by response to said action on the door handle, as is symbolized by arrow 34.

    Le temps total mis par le dispositif électronique de reconnaissance 26 pour dialoguer avec le dispositif 27, identifier le bon propriétaire et émettre le signal de décondamnation, plus le temps mis par le dispositif électromécanique de condamnation/décondamnation 15 pour faire passer le levier 18 et le téton 22 de leur position correspondant à l'état condamné (figure 2) à leur position correspondant à l'état décondamné de la serrure (figure 1), en réponse à l'émission du signal de décondamnation, est généralement plus long que le temps de réponse du mécanisme de libération du pêne 1, c'est-à-dire le temps mis par la tringle de commande 7 pour effectuer sa course d'actionnement en réponse à l'actionnement de la poignée de porte. La tringle de commande 7 a donc généralement terminé son mouvement d'actionnement alors que le levier 18 et le téton 22 n'ont pas encore été mis dans leur position correspondant à l'état décondamné de la serrure. A ce moment, malgré l'émission du signal de décondamnation, le mouvement d'actionnement de la tringle de commande 7 n'a pas d'effet sur le cliquet 5.The total time taken by the electronic device recognition 26 to interact with the device 27, identify the correct owner and send the unlocking signal, the longer the time taken by the electromechanical locking / unlocking device 15 to move the lever 18 and the stud 22 from their position corresponding to the condemned state (figure 2) at their position corresponding to the unlocked state of the lock (Figure 1), in response when issuing the unlocking signal, is generally longer that the response time of the bolt release mechanism 1, i.e. the time taken by the control rod 7 to run its course actuation in response to actuation of the door handle. The control rod 7 has therefore generally finished its movement actuation while the lever 18 and the stud 22 have not yet been put in their position corresponding to the unlocked state of the lock. At this time, despite the emission of the unlocking signal, the actuation movement of the control rod 7 has no effect on the pawl 5.

    Le dispositif à accumulation d'énergie formé par les leviers 8 et 11 et par le ressort 13 permet de remédier à cela, comme on va maintenant le voir au cours de la description du fonctionnement de la serrure selon l'invention.The energy storage device formed by the levers 8 and 11 and by the spring 13 makes it possible to remedy this, as we will now see it during the description of how the lock according to the invention.

    Si la serrure est dans l'état décondamné (figure 1), les deux leviers 8 et 11 sont rendus solidaires l'un de l'autre par la biellette 21 et son téton 22, comme indiqué plus haut. De ce fait, si l'utilisateur tire sur la poignée de porte, la tringle de commande 7 se déplace dans le sens de la flèche F2 et fait basculer, dans le sens de la flèche F3, le levier 8 qui entraíne avec lui le levier 11, lequel entraíne lui-même le cliquet 5 en le faisant pivoter dans le sens de la flèche F4 autour de l'axe 6, libérant ainsi le pêne 1. La porte peut être alors ouverte en continuant à tirer sur la poignée de porte.If the lock is in the unlocked state (Figure 1), the two levers 8 and 11 are made integral with each other by the link 21 and its nipple 22, as indicated above. Therefore, if the user pulls on the door handle, the control rod 7 moves in the direction of arrow F2 and toggles, in the direction of arrow F3, the lever 8 which carries with it lever 11, which itself drives the ratchet 5 by rotating it in the direction of arrow F4 around axis 6, thus releasing the bolt 1. The door can then be opened by continuing to pull the door handle.

    Si la serrure est à l'état condamné (figure 2) et si une personne non autorisée tire sur la poignée de porte, la tringle de commande 7 fait, là encore, basculer le levier 8 dans le sens de la flèche F3 autour de l'axe 9 (figure 3). Toutefois, dans ce cas, du fait que le téton 22 de la biellette 21 se trouve maintenant à l'extrémité de la lumière 12 la plus proche de l'axe 9, en regard de la partie 14b de la lumière 14 du levier 8, ce dernier n'entraíne pas, au cours de son mouvement de basculement, le levier 11 car le téton 22 pénètre dans ladite partie 14b de la lumière 14. En outre, au cours du mouvement de basculement du levier 8, le ressort 13 est comprimé et tend ainsi à faire tourner le levier 11 dans le sens de la flèche F3 autour de l'axe 9, mais ce levier 11 ne tourne pas étant donné que le levier de condamnation 18 l'en empêche par son doigt 18a en butée sur la patte 11b du levier 11. Ce dernier est donc bloqué et le cliquet 5 ne peut être amené dans sa position "échappée" ou "effacée", de sorte que la gâche 3 reste prisonnière du pêne 1 et que la porte ne peut être ouverte.If the lock is in the locked state (Figure 2) and if an unauthorized person pulls on the door handle, the control rod 7 again causes the lever 8 to tilt in the direction of the arrow F3 around the axis 9 (figure 3). However, in this case, due to the fact that the stud 22 of the link 21 is now at the end of the lumen 12 closest to the axis 9, opposite the part 14b of the lumen 14 of the lever 8 , the latter does not cause, during its tilting movement, the lever 11 because the stud 22 enters said portion 14b of the light 14. In addition, during the tilting movement of the lever 8, the spring 13 is compressed and thus tends to rotate the lever 11 in the direction of the arrow F3 around the axis 9, but this lever 11 does not rotate since the locking lever 18 prevents it by its finger 18 a in abutment on the tab 11 b of the lever 11. The latter is therefore blocked and the pawl 5 cannot be brought into its "escaped" or "erased" position, so that the keeper 3 remains trapped in the bolt 1 and the door does not can be opened.

    Si la serrure est dans un état condamné (figure 2) et que le propriétaire du véhicule ou une personne autorisée portant un dispositif identifiant électronique 27 approprié tire sur la poignée de porte, dans une première phase il se produit exactement la même chose que dans le cas précédent. Le levier 8 bascule autour de l'axe 9, le ressort 13 est comprimé, mais le levier 11 reste bloqué par le doigt 18a du levier de condamnation 18. Dans une deuxième phase qui suit très rapidement après la première phase, la personne ayant été reconnue par le dispositif électronique de reconnaissance 26, celui-ci active le dispositif électrique d'actionnement 16 (par exemple un électro-aimant) qui agit par la tige de liaison 17 sur le levier de condamnation 18 pour le faire pivoter dans le sens de la flèche F5 autour de l'axe 19 (figure 4) et l'amener dans la position décondamnée (figure 5). Au cours de ce mouvement de rotation du levier 18, dès que son doigt 18a a libéré la patte 11b du levier 11 (figure 4), celui-ci est quasi instantanément entraíné en rotation dans le sens de la flèche F6 autour de l'axe 9, grâce à l'énergie gratuite qui avait été fournie par l'utilisateur et emmagasinée dans le ressort 13 au cours de la première phase. En basculant dans le sens de la flèche F6, le levier 11 entraíne avec lui le cliquet 5. Ce dernier libère donc le pêne 1, de sorte que la porte peut être ouverte.If the lock is in a locked condition (Figure 2) and the owner of the vehicle or an authorized person wearing an appropriate electronic identification device 27 pulls on the door handle, in the first phase exactly the same thing happens as in the previous case. The lever 8 rocks around the axis 9, the spring 13 is compressed, but the lever 11 remains blocked by the finger 18 a of the locking lever 18. In a second phase which follows very quickly after the first phase, the person having been recognized by the electronic recognition device 26, this activates the electrical actuation device 16 (for example an electromagnet) which acts by the connecting rod 17 on the locking lever 18 to rotate it in the direction arrow F5 around axis 19 (Figure 4) and bring it into the unlocked position (Figure 5). During this rotation movement of the lever 18, as soon as his finger 18 has released the tab 11b of the lever 11 (FIG. 4), the latter is almost instantaneously rotated in the direction of the arrow F6 around the axis 9, thanks to the free energy which had been supplied by the user and stored in the spring 13 during the first phase. By tilting in the direction of arrow F6, the lever 11 drives with it the pawl 5. The latter therefore releases the bolt 1, so that the door can be opened.

    On notera que peu de temps après le commencement du mouvement de rotation du levier 18 dans le sens de la flèche F5 autour de l'axe 19, la patte 11b, le doigt 18a, et le centre de l'axe 19 cessent d'être alignés et, sous l'action du ressort 13 qui pousse la patte 11b contre l'extrémité du doigt 18a, du levier 18, ce doigt 18a est soumis à une force dont le moment par rapport à l'axe 19 n'est plus nul et tend aussi à faire tourner le levier 18 dans le sens de la flèche F5, aidant ainsi le dispositif électrique d'actionnement 16 à faire tourner le levier 18 pour l'amener dans sa position décondamnée. Il en résulte que le dispositif électrique d'actionnement 16 n'a pas besoin de fournir une énergie importante, puisqu'il lui suffit de vaincre, en plus de la fonction condamnation, le petit frottement entre la patte 11b et l'extrémité du doigt 18a du levier 18 au commencement du mouvement de décondamnation de ce levier 18.It will be noted that shortly after the beginning of the movement of rotation of the lever 18 in the direction of the arrow F5 around the axis 19, the tab 11 b , the finger 18 a , and the center of the axis 19 cease d '' be aligned and, under the action of the spring 13 which pushes the tab 11 b against the end of the finger 18 a , of the lever 18, this finger 18 a is subjected to a force whose moment relative to the axis 19 is no longer zero and also tends to rotate the lever 18 in the direction of the arrow F5, thus helping the electrical actuating device 16 to rotate the lever 18 to bring it into its unlocked position. As a result, the electric actuating device 16 does not need to provide significant energy, since it suffices to overcome, in addition to the locking function, the small friction between the tab 11 b and the end of the finger 18 has lever 18 at the beginning of the unlocking movement of this lever 18.

    En même temps que le levier 18 commence à tourner vers sa position décondamnée (figure 4), sa lumière 24 se déplace et comprime le ressort 25, puisque la biellette 21 ne peut pas tourner étant donné, qu'à ce moment, son téton 22 est en appui contre le bord de la partie 14b de la lumière 14 du levier 8. Dès que la patte 11b du levier 11 est libérée par le doigt 18a du levier de condamnation 18, et que le levier 11 bascule dans le sens de la flèche F6, sa lumière 12 agit sur le téton 22 de la biellette 21 afin de le ramener vers la branche 14a de la lumière 14 du levier 8. Dès que la lumière 12 du levier 11 coïncide avec ladite partie 14a de la lumière 14, le téton 22 de la biellette 21 est repoussé par le ressort 25 jusqu'à l'extrémité de la partie 14a de la lumière 14 la plus éloignée de l'axe 9 (figure 5). Ainsi, lorsque la poignée de porte est ensuite relâchée, la serrure se trouve dans un état décondamné.At the same time as the lever 18 begins to rotate towards its unlocked position (FIG. 4), its light 24 moves and compresses the spring 25, since the link 21 cannot rotate given that, at this moment, its stud 22 is in abutment against the edge of the part 14 b of the light 14 of the lever 8. As soon as the tab 11 b of the lever 11 is released by the finger 18 a of the locking lever 18, and that the lever 11 rocks in the direction arrow F6, its light 12 acts on the stud 22 of the link 21 in order to bring it back towards the branch 14 a of the light 14 of the lever 8. As soon as the light 12 of the lever 11 coincides with said part 14 a of the light 14, the stud 22 of the link 21 is pushed back by the spring 25 to the end of the part 14a of the light 14 furthest from the axis 9 (FIG. 5). When the door handle is then released, the lock is in an unlocked state.

    Afin que l'utilisateur, au moment où il tire sur la poignée de porte, ait sensiblement la même sensation que la serrure soit condamnée ou décondamnée, le ressort 13 est de préférence installé entre les deux pattes 8a et 11b de telle façon que, lorsque la serrure est dans l'état représenté sur la figure 1 ou 2, il soit dans un état pré-bandé ou pré-contraint tel que l'effort à fournir par l'utilisateur pour comprimer le ressort lorsque la serrure est à l'état condamné, soit le même ou sensiblement le même que l'effort à fournir par l'utilisateur pour vaincre les frottements entre le cliquet 5 et le pêne 1 quand la serrure est décondamnée.So that the user, when he pulls on the door handle, has substantially the same feeling that the lock is locked or unlocked, the spring 13 is preferably installed between the two tabs 8 a and 11 b so that , when the lock is in the state shown in FIG. 1 or 2, it is in a pre-bandaged or pre-stressed state such as the effort to be provided by the user to compress the spring when the lock is at 'condemned state, either the same or substantially the same as the effort to be provided by the user to overcome the friction between the pawl 5 and the bolt 1 when the lock is unlocked.

    Avec la serrure décrite ci-dessus, on voit donc que le pêne 1 peut être libéré de façon sûre par une action unique sur la poignée de la porte du véhicule, en réponse à l'émission du signal de décondamnation produit par le dispositif électronique de reconnaissance 26, et cela quel que soit l'état condamné ou décondamné de la serrure.With the lock described above, we can see that the bolt 1 can be safely released by a single action on the handle the vehicle door, in response to the transmission of the signal unlocking produced by the electronic recognition device 26, regardless of the condemned or unlocked state of the lock.

    Dans le cas où le véhicule est équipé d'un système centralisé de condamnation/décondamnation, le signal de décondamnation émis sur la ligne 31 peut être aussi utilisé pour décondamner les serrures des autres portes ou ouvrants du véhicule.In case the vehicle is equipped with a system central locking / unlocking, the unlocking signal issued on line 31 can also be used to unlock the locks on other doors or doors of the vehicle.

    En se référant maintenant aux figures 6 à 12, un deuxième mode de réalisation de la serrure de l'invention va être décrit, pour lequel les éléments identiques ou analogues à ceux du premier mode de réalisation porte les mêmes chiffres de référence augmentés d'une centaine.Referring now to Figures 6 to 12, a second embodiment of the lock of the invention will be described, for which elements identical or analogous to those of the first mode of achievement has the same reference numbers increased by hundred.

    Sur ces figures, seul le pion d'actionnement 105 du cliquet est représenté. De façon connue en soi, ce pion 105 traverse une ouverture allongée, ménagée dans une paroi séparant le compartiment de rétention de la serrure, contenant notamment le pêne et le cliquet, du compartiment de cinématique, contenant les leviers d'ouverture et de condamnation de la serrure.In these figures, only the actuating pin 105 of the pawl is represented. In a manner known per se, this pin 105 crosses a elongated opening, formed in a wall separating the compartment of retention of the lock, containing in particular the bolt and the ratchet, kinematics compartment, containing the opening and locking the lock.

    Sur la figure 6, la poignée extérieure de portière est destinée à être reliée par un organe de commande, constitué par exemple par une tringle, à une extrémité 107 d'un levier basculant 108. Ce levier basculant 108 est monté pivotant sur un axe 109, à l'opposé de l'extrémité 107. Le levier 108 est destiné à basculer dans le sens anti-horaire, lorsque l'utilisateur exerce une traction sur la poignée de porte.In Figure 6, the exterior door handle is intended to be connected by a control member, consisting of example by a rod, at one end 107 of a rocking lever 108. This rocking lever 108 is pivotally mounted on an axis 109, opposite from the end 107. The lever 108 is intended to tilt in the direction anti-clockwise, when the user pulls the handle door.

    Un deuxième levier 111 est monté basculant sur l'axe 109 et comporte une branche 110 apte à coopérer avec le pion de cliquet 105 pour l'entraíner avec lui dans son mouvement de basculement.A second lever 111 is mounted tilting on the axis 109 and comprises a branch 110 capable of cooperating with the pawl pin 105 to train him with him in his tilting movement.

    Le levier 111 comporte, en saillie, sur l'une de ses faces et à distance de l'axe 109, deux pattes 111a et 111b qui sont espacées l'une de l'autre, pour recevoir entre elles le levier 108 précité. Le levier 111 comporte, en outre, une lumière oblongue 112 qui s'étend sensiblement dans une direction radiale par rapport à l'axe 109. Le levier 108 présente également une patte 108a qui fait saillie sur l'une de ses faces à distance de l'axe 109 et qui est maintenue en appui contre la patte 111a du levier 111 par un moyen élastique de compression 113, par exemple un ressort hélicoïdal. Le ressort 113 prend appui, à son extrémité opposée, sur la patte 111b du levier 111. Le levier 108 comporte également une lumière 114 sensiblement en L, comportant deux parties 114a et 114b. La partie 114a coïncide avec la lumière oblongue 112, lorsque les pattes 108a et 111a sont en appui l'une contre l'autre, comme illustré sur les figures 6 à 8.The lever 111 comprises, projecting, on one of its faces and at a distance from the axis 109, two tabs 111 a and 111 b which are spaced from one another, to receive the aforementioned lever 108 between them . The lever 111 further comprises an oblong slot 112 which extends substantially in a radial direction relative to the axis 109. The lever 108 also has a tab 108 a which projects on one of its remote faces of the axis 109 and which is held in abutment against the tab 111 a of the lever 111 by an elastic compression means 113, for example a helical spring. The spring 113 is supported, at its opposite end, on the tab 111 b of the lever 111. The lever 108 also includes a light 114 substantially L-shaped, comprising two parts 114 a and 114 b . Part 114 coincides with the oblong slot 112, when the legs 108a and 111a are pressed against each other, as shown in Figures 6 to 8.

    Le dispositif électromécanique de condamnation/ décondamnation 115 comporte, ici, un dispositif électrique d'actionnement extérieur 116 qui comporte par exemple un moteur électrique entraínant, par l'intermédiaire d'un train d'engrenages, une vis sans fin 116a représentée par un axe sur la figure 6, sur laquelle coulisse axialement un écrou 117 portant une paire de branches formant une fourchette apte à déplacer une patte repliée à angle droit 118b d'un levier de condamnation extérieure 118 (LCE), ladite patte 118b traversant une paroi séparant le compartiment de cinématique et le compartiment électrique de la serrure, dans lequel est logé le dispositif électromécanique 115 précité.The electromechanical locking / unlocking device 115 comprises here an actuating external electrical device 116 which comprises for example an electric motor driving, through a gear train, a worm 116 is represented by a axis in FIG. 6, on which axially slides a nut 117 carrying a pair of branches forming a fork capable of moving a lug folded at right angles 118 b of an external locking lever 118 (LCE), said lug 118 b passing through a wall separating the kinematics compartment and the electrical compartment of the lock, in which the above-mentioned electromechanical device 115 is housed.

    Ce dispositif électromécanique 115 comporte, en outre, un dispositif électrique d'actionnement intérieur 148 qui comporte, de manière connue en soi, un moteur électrique relié par une chaíne d'engrenages, à un levier 148a représenté en traits interrompus sur la figure 6, situé dans le compartiment électrique de la serrure, ce levier 148a étant solidaire en rotation, par un axe traversant ladite paroi séparatrice, d'une fourchette 148b, apte à déplacer un levier de condamnation intérieure 144 (LCI) dont le fonctionnement sera expliqué plus loin.This electromechanical device 115 further comprises an electrical internal actuation device 148 which comprises, in a manner known per se, an electric motor connected by a chain of gears, to a lever 148a shown in broken lines in FIG. 6, located in the electrical compartment of the lock, this lever 148 a being integral in rotation, by an axis passing through said separating wall, with a fork 148 b , able to move an internal locking lever 144 (LCI) whose operation will be explained further.

    Le LCE 118 est monté pivotant sur un axe 119, parallèle à l'axe 109 précité, et comporte un doigt de blocage 118a qui se trouve en vis-à-vis de la patte 111b du levier 111, dans l'état condamné extérieur de la serrure, comme illustré sur les figures 7 et 8, empêchant ainsi le levier 111 de basculer autour de l'axe 109.The LCE 118 is pivotally mounted on an axis 119, parallel to the aforementioned axis 109, and includes a locking finger 118 a which is located opposite the tab 111 b of the lever 111, in the locked state outside of the lock, as illustrated in FIGS. 7 and 8, thus preventing the lever 111 from tilting around the axis 109.

    Une biellette 121 comporte à ses deux extrémités des tétons 122 et 123, le téton 122 étant engagé dans les lumières 112 et 114 des leviers 111 et 108, alors que l'autre téton 123 est engagé dans une lumière oblongue 124 du LCE 118. Le téton 123 est mobile dans la lumière 124 à l'encontre de la force de rappel d'un ressort 125.A link 121 has at its two ends nipples 122 and 123, the nipple 122 being engaged in the slots 112 and 114 of levers 111 and 108, while the other stud 123 is engaged in an oblong lumen 124 of the LCE 118. The stud 123 is movable in the light 124 against the return force of a spring 125.

    Le LCE 118 comporte, sur sa branche opposée à celle munie de la lumière 124, une ouverture oblongue 120, sensiblement en arc de cercle, s'étendant sensiblement radialement entre l'axe 119 et la patte 118b du LCE 118. L'ouverture 120 est sensiblement à angle droit par rapport au doigt de blocage 118a.The LCE 118 comprises, on its branch opposite to that provided with the light 124, an oblong opening 120, substantially in an arc, extending substantially radially between the axis 119 and the lug 118 b of the LCE 118. The opening 120 is substantially at right angles to the locking finger 118 a .

    Le LCI 144 est monté pivotant sur un axe 145 parallèle à l'axe 119 précité et comporte un doigt excentré 147 apte à être déplacé par la fourchette 148b du dispositif d'actionnement intérieur 148, pour faire basculer le LCI 144 entre une position décondamnée intérieure illustrée sur les figures 6 et 7, et une position condamnée intérieure illustrée sur les figures 8 et 9. Le LCI 144 comporte, sur une branche, une ouverture oblongue 146 s'étendant sensiblement à angle droit par rapport à l'ouverture 120 du LCE 118. Comme mieux visible sur la figure 12, l'ouverture 120 du LCE 118 et l'ouverture 146 du LCI 144 sont traversées par un pion d'entraínement ou d'accouplement 149.The LCI 144 is pivotally mounted on an axis 145 parallel to the aforementioned axis 119 and has an eccentric finger 147 capable of being moved by the fork 148 b of the internal actuating device 148, in order to tilt the LCI 144 between a unlocked position interior illustrated in FIGS. 6 and 7, and an interior locked position illustrated in FIGS. 8 and 9. The LCI 144 has, on one branch, an oblong opening 146 extending substantially at right angles to the opening 120 of the LCE 118. As best seen in FIG. 12, the opening 120 of the LCE 118 and the opening 146 of the LCI 144 are crossed by a drive or coupling pin 149.

    La serrure selon ce deuxième mode de réalisation de l'invention comporte, en outre, un levier supplémentaire 140, monté pivotant sur l'axe 119 précité et intercalé entre le LCE 118 et le LCI 144, comme illustré sur la figure 12. Le levier 140 comporte une fourchette 141 dans laquelle peut être inséré un moyen de liaison à une tirette de frise intérieure de la portière. Le levier 140 comporte, en outre, une rampe d'actionnement 142 apte à coopérer avec un organe de commande d'ouverture intérieure de la portière, pour faire basculer le levier 140 dans le sens anti-horaire. Le levier 140 comporte, en outre, une ouverture 143 sensiblement en forme de L, dont une partie correspond à l'ouverture 120 du LCE 118 et dont l'autre partie correspond à l'ouverture 146 du LCI 144, en position condamnée intérieure.The lock according to this second embodiment of the invention further comprises an additional lever 140, mounted pivoting on the aforementioned axis 119 and interposed between the LCE 118 and the LCI 144, as illustrated in FIG. 12. The lever 140 has a fork 141 into which can be inserted a means of connection to a interior door panel. The lever 140 comprises, in in addition, an actuating ramp 142 capable of cooperating with a member door opening control switch lever 140 counterclockwise. The lever 140 comprises, in in addition, a substantially L-shaped opening 143, part of which corresponds to opening 120 of LCE 118 and of which the other part corresponds to opening 146 of LCI 144, in the locked position interior.

    On peut noter qu'en l'absence du dispositif d' actionnement intérieur 144 à 149, le LCE 118 peut intégrer la rampe 142 et la fourchette 141, sans levier supplémentaire. Dans ce cas, la serrure ne comporte pas la fonction de supercondamnation, dans laquelle la serrure est condamnée vis-à-vis de l'intérieur et de l'extérieur.It can be noted that in the absence of the actuating device interior 144 to 149, the LCE 118 can integrate the ramp 142 and the fork 141, without additional lever. In this case, the lock does not does not have the function of super-conviction, in which the lock is condemned vis-à-vis the interior and exterior.

    Le pion d'entraínement 149 comporte une collerette intermédiaire 150, de plus grand diamètre, intercalée entre le LCI 144 et le levier supplémentaire 140, pour bloquer en position axiale le pion d'entraínement 149 par rapport aux différents leviers.The training pin 149 has a flange intermediate 150, larger diameter, sandwiched between LCI 144 and the additional lever 140, to lock the pin in axial position 149 with respect to the various levers.

    Le fonctionnement de cette serrure va maintenant être décrit en référence aux figures 6 à 11.The operation of this lock will now be described with reference to Figures 6 to 11.

    Sur la figure 6, la serrure est dans un état décondamné vis-à-vis de l'intérieur et de l'extérieur. Sous l'action manuelle de l'utilisateur situé à l'intérieur du véhicule, sur une tirette de frise interne de la portière agissant sur la fourchette 141, le levier 140 est pivoté dans le sens horaire, ce qui entraíne par l'intermédiaire du pion d'entraínement 149 le basculement dans le sens horaire du LCE 118, jusqu' à ce que son doigt de blocage 118a se trouve en face de la patte 111b du levier 111, comme illustré sur la figure 7. Le pivotement du LCE 118 entraíne le coulissement de l'écrou 117 sur sa vis sans fin 116a qui peut tourner librement par rapport à son moteur électrique, et le pion d'entraínement 149 peut librement coulisser dans l'ouverture oblongue 146 du LCI 144, sans déplacer ce dernier.In Figure 6, the lock is in a unlocked state vis-à-vis the interior and exterior. Under the manual action of the user located inside the vehicle, on an internal frieze zipper of the door acting on the fork 141, the lever 140 is pivoted clockwise, which drives through the drive pin 149 tilting clockwise of the LCE 118, until its locking finger 118 a is opposite the tab 111 b of the lever 111, as illustrated in FIG. 7. The pivoting of the LCE 118 causes the nut 117 to slide on its worm 116 a which can rotate freely relative to its electric motor, and the drive pin 149 can freely slide in the oblong opening 146 of LCI 144, without moving this latest.

    A partir de la position illustrée sur la figure 7, un utilisateur peut actionner la poignée intérieure de portière, ce qui provoque le déplacement du cliquet 105 vers sa position échappée, tout en agissant sur la rampe 142 du levier 140, pour le faire basculer dans le sens anti-horaire. Ce basculement du levier 140 provoque le basculement dans le sens anti-horaire du LCE 118, jusqu' à sa position décondamnée illustrée sur la figure 6. La rampe 142 constitue donc un moyen de décondamnation automatique à l'ouverture de la portière, lorsque la portière n'est pas condamnée vis-à-vis de l'intérieur.From the position illustrated in Figure 7, a user can operate the interior door handle, which causes the pawl 105 to move towards its escaped position, while by acting on the ramp 142 of the lever 140, to make it tilt in counterclockwise. This tilting of the lever 140 causes the anti-clockwise tilting of the LCE 118 to its position unlocked illustrated in FIG. 6. The ramp 142 therefore constitutes a automatic unlocking means when the door is opened, when the door is not condemned vis-à-vis the interior.

    Pour passer de la figure 6 à la figure 7, il est également possible d'envoyer un signal de condamnation extérieure au véhicule, pour provoquer, par l'intermédiaire du moteur électrique, le déplacement de l'écrou 117, entraínant le basculement du LCE 118 dans le sens horaire, jusqu'à sa position condamnée extérieure. Dans ce cas, la fourchette 141 du levier 140 entraíne le déplacement de la tirette de frise vers sa position condamnée.To go from figure 6 to figure 7, it is also possible to send an external condemnation signal to the vehicle, to cause, through the electric motor, the displacement of the nut 117, causing the tilting of the LCE 118 clockwise to its outer locked position. In this case, the fork 141 of the lever 140 causes the movement of the zipper frieze to its doomed position.

    En revanche, lorsque le véhicule reçoit un signal de condamnation intérieure, le moteur électrique associé provoque le basculement de la fourchette 148b pour faire pivoter le LCI 144 dans le sens anti-horaire jusqu'à sa position illustrée sur la figure 8. Lors du basculement du LCI 144, le pion d'entraínement 149 coulisse librement dans les ouvertures oblongues superposées 120 et 143 des leviers 118 et 140. Dans la position condamnée intérieure, le pion d'entraínement 149 est en vis-à-vis de l'autre portion de l'ouverture 143 en L du levier 140. Ainsi, si un utilisateur actionne la poignée intérieure de portière ou la tirette de frise, le pivotement du levier 140 dans le sens anti-horaire n'entraíne pas le pivotement du LCE 118, de sorte que l'on a supprimé la décondamnation automatique à l'ouverture. La chaíne cinématique du mécanisme d'ouverture et de condamnation intérieure n' est pas représentée et est connue en soi.On the other hand, when the vehicle receives an interior locking signal, the associated electric motor causes the fork 148 b to tilt to rotate the LCI 144 counterclockwise to its position illustrated in FIG. 8. tilting of the LCI 144, the drive pin 149 slides freely in the superimposed oblong openings 120 and 143 of the levers 118 and 140. In the inner locked position, the drive pin 149 is opposite the other portion of the opening 143 in L of the lever 140. Thus, if a user actuates the interior door handle or the frieze zipper, the pivoting of the lever 140 counterclockwise does not cause the pivoting of the LCE 118, so that the automatic unlocking on opening was eliminated. The kinematic chain of the opening and interior locking mechanism is not shown and is known per se.

    A partir de la position illustrée sur la figure 8, si un utilisateur actionne la poignée extérieure de portière, le levier 108 bascule dans le sens anti-horaire, ce qui comprime le ressort 113, car le levier 111 est bloqué en rotation par le doigt 118a du LCE 118, comme illustré à la figure 9.From the position illustrated in FIG. 8, if a user actuates the exterior door handle, the lever 108 swings counterclockwise, which compresses the spring 113, because the lever 111 is locked in rotation by the finger 118 a of LCE 118, as illustrated in Figure 9.

    Lorsque le véhicule reçoit un signal de décondamnation, les moteurs électriques sont alimentés pour décondamner à la fois vis-à-vis de l'intérieur et de l'extérieur, comme illustré sur la figure 10. En effet, sur cette figure, on constate que le LCI 144 bascule dans le sens horaire en même temps que le LCE 118 bascule dans le sens horaire vers leur position décondamnée respective. When the vehicle receives an unlocking signal, the electric motors are powered to unlock both vis-à-vis from the inside and from the outside, as illustrated in figure 10. In Indeed, in this figure, we see that the LCI 144 rocks in the direction clockwise at the same time as the LCE 118 switches clockwise towards their respective unlocked position.

    Après un mouvement suffisant du levier 118 pour que son doigt de blocage 118a ne soit plus en vis-à-vis de la patte 111b, le levier 111 est libre de pivoter, et bascule sous l'action de l'énergie emmagasinée par le ressort 113, ce qui provoque le déplacement du pion de cliquet 105, par la branche 110 du levier 111, comme illustré à la figure 11. Simultanément le levier 144 continue son basculement vers sa position état décondamné sans gêner le basculement du levier 118.After sufficient movement of the lever 118 so that its locking finger 118 a is no longer facing the tab 111 b , the lever 111 is free to pivot, and tilts under the action of the energy stored by the spring 113, which causes the displacement of the pawl pin 105, by the branch 110 of the lever 111, as illustrated in FIG. 11. Simultaneously the lever 144 continues its tilting towards its unlocked state position without hindering the tilting of the lever 118.

    Lorsque l'utilisateur relâche la poignée extérieure de portière, la serrure revient à l'état illustré à la figure 6.When the user releases the outer handle of door, the lock returns to the state illustrated in FIG. 6.

    Il peut arriver qu'un utilisateur, par exemple un enfant, tire sur la poignée extérieure de portière, avant qu'un autre utilisateur, par exemple un parent, actionne un bouton de décondamnation sur son boítier de télécommande. Dans ce cas, l'ouverture de la portière s'effectuera, sans avoir à effectuer une deuxième traction sur la poignée extérieure de portière.It may happen that a user, for example a child, pulls on the outside door handle, before another user, for example a parent, activates a unlocking button on his remote control unit. In this case, opening the door will be carried out, without having to perform a second pull on the handle door exterior.

    Il va de soi que le mode de réalisation de l'invention qui a été décrit ci-dessus a été donné à titre d'exemple purement indicatif et nullement limitatif, et que de nombreuses modifications peuvent être apportées par l'homme de l'art sans pour autant sortir du cadre de l'invention {tel que définie par les revendications}. C'est ainsi, notamment, que le ressort hélicoïdal 13 peut être remplacé par un autre type de ressort, par exemple un ressort pneumatique.It goes without saying that the embodiment of the invention which has been described above was given as a purely indicative example and in no way limitative, and that many modifications can be made by those skilled in the art without departing from the scope of the invention {as defined by the claims}. Thus, in particular, that the helical spring 13 can be replaced by another type of spring, for example a spring pneumatic.
