Description

Serrure pour un ouvrant de véhicule automobile Lock for an opening of a motor vehicle
La présente invention concerne une serrure pour un ouvrant de véhicule automobile. The present invention relates to a lock for an opening of a motor vehicle.
Une serrure de véhicule automobile est destinée à être montée sur un ouvrant de véhicule automobile et comporte typiquement un pêne destiné à pivoter autour d'une gâche fixée sur la structure du véhicule automobile afin d'assurer la fermeture de l'ouvrant. L'ouverture de l'ouvrant est réalisée par une rotation du pêne en sens inverse. Dans des conditions normales d'utilisation, la rotation en sens inverse, dit « sens d'ouverture de l'ouvrant », est réalisée par le déplacement de la poignée extérieure qui est reliée à la serrure par un moyen de commande qui agit sur un levier d'ouverture dit extérieur afin de faire pivoter ce dernier qui libère à son tour le pêne via un dispositif d'accrochage dans la direction souhaitée.  A lock of a motor vehicle is intended to be mounted on an opening of a motor vehicle and typically comprises a bolt for pivoting around a striker fixed to the structure of the motor vehicle to ensure the closing of the opening. The opening of the opening is performed by a rotation of the bolt in the opposite direction. Under normal conditions of use, the rotation in the opposite direction, called "opening direction of the leaf", is achieved by the movement of the outer handle which is connected to the lock by a control means which acts on a opening said lever outside to rotate the latter which releases in turn the bolt via a shackle in the desired direction.
Cependant, en cas de choc latéral, la force inertielle exercée sur l'ouvrant peut exercer une force de traction suffisante sur le moyen de commande et agir sur le levier d'ouverture pour commander l'ouverture de la serrure et donc la libération de l'ouvrant.  However, in the event of a side impact, the inertial force exerted on the opening can exert sufficient traction force on the control means and act on the opening lever to control the opening of the lock and thus the release of the door. 'opening.
Pour éviter cela, il existe des serrures configurées pour ne pas avoir de mouvement de cinématique lors d'un choc ou inhiber l'effet du mouvement. Ainsi, il est proposé des solutions de blocage de la chaîne cinématique par effort résistant, tel que les ressorts, ou par blocage. Cette dernière solution permet une meilleure robustesse de la serrure vis-à-vis des différentes familles de choc.  To avoid this, there are locks configured to not have kinematic movement during a shock or to inhibit the effect of movement. Thus, it is proposed solutions for blocking the drive train by resistant force, such as springs, or by blocking. This last solution allows a better robustness of the lock vis-à-vis the different families of shock.
Le blocage de serrure peut être réalisé par un obstacle externe engendrant une déformation, suite à un mouvement inertiel temporaire ou permanent, avec une possibilité de remise à l'état avant choc dans ce dernier cas.  The lock lock can be achieved by an external obstacle causing deformation, following a temporary or permanent inertial movement, with a possibility of return to the state before shock in the latter case.
Le blocage par obstacle extérieur est typiquement réalisé par un système qui intervient par déformation de la porte. Si une déformation est supérieure à une valeur seuil, alors il y a un obstacle extérieur qui bloque le mouvement de la chaîne d'ouverture.  Blocking by external obstacle is typically achieved by a system that intervenes by deformation of the door. If a deformation is greater than a threshold value, then there is an external obstacle that blocks the movement of the opening chain.
La consigne de blocage vient typiquement de déformation de la tôle du véhicule. La déformation de cette tôle va venir positionner un obstacle appartenant soit à la serrure, soit à la tôlerie, en face du levier d'ouverture extérieur. Le levier intervenant directement dans l'ouverture de la serrure, cette dernière ne peut se faire.  The locking instruction typically comes from deformation of the vehicle sheet. The deformation of this sheet will come to position an obstacle belonging either to the lock or the sheet metal, opposite the opening lever outside. The lever intervenes directly in the opening of the lock, the latter can not be done.
Cependant, un tel système nécessite une adaptation à la géométrie de la porte, une déformation de ladite porte, une insensibilité au mouvement de la poignée et l'impossibilité d'ouverture de la porte après le choc. However, such a system requires an adaptation to the geometry of the door, a deformation of said door, an insensitivity to the movement of the handle and the impossibility opening the door after the shock.
Il existe le blocage temporaire par mouvement inertiel réalisé par un système qui réagit à une accélération anormale de la serrure. Si la valeur et la durée de l'accélération sont supérieures à une valeur seuil, alors une biellette se déplace pour bloquer l'ouverture ou débrayer le mouvement.  There is the temporary blocking by inertial movement realized by a system that reacts to an abnormal acceleration of the lock. If the value and duration of the acceleration are greater than a threshold value, then a link moves to block the opening or to disengage the movement.
Dans ces conceptions, une cale de condamnation avec ressort est typiquement accrochée au levier d'ouverture extérieur. Un effort inertiel déplace ladite cale sur le côté pendant le mouvement dudit levier. Une goulotte accueille la cale et l'empêche de redescendre le temps que le levier d'ouverture extérieur est activé. Le levier d'ouverture extérieur ne pouvant être activé, il n'y a pas d'ouverture. Dans ces conceptions, il est possible de remettre à l'état initial après la survenue du choc. La cale revenant à sa position initiale lors du retour en position de repos du levier d'ouverture.  In these designs, a spring-loaded shim is typically attached to the outer opening lever. Inertial force moves said shim to the side during movement of said lever. A chute receives the hold and prevents it from going back down while the outside opening lever is activated. The external opening lever can not be activated, there is no opening. In these designs, it is possible to reset after the occurrence of the shock. The shim returning to its initial position when returning to the rest position of the opening lever.
Cependant, ce système nécessite une bonne connaissance du choc, notamment du mouvement de la poignée en cas de choc et une certaine synchronisation des mouvements de réglage.  However, this system requires a good knowledge of the shock, including the movement of the handle in case of impact and a certain synchronization of the adjustment movements.
Un but de l'invention est de proposer une serrure pour un véhicule automobile qui permet d'interdire l'ouverture extérieure ou intérieure sous l'effet d'une force inertielle, qu'elle soit unique ou multiple, appliquée à la serrure durant un accident de voiture, tout en permettant, une fois la force inertielle redevenue nulle, la réouverture de la serrure sans présenter les inconvénients de l'art antérieur.  An object of the invention is to provide a lock for a motor vehicle that allows to prohibit the outer or inner opening under the effect of an inertial force, whether single or multiple, applied to the lock during a car accident, while allowing, once the inertial force back to zero, the reopening of the lock without the disadvantages of the prior art.
A cet effet, l'invention a pour objet une serrure pour un ouvrant de véhicule automobile comportant :  For this purpose, the invention relates to a lock for an opening of a motor vehicle comprising:
- un moyen de commande mobile,  a mobile control means,
- un levier d'ouverture dudit ouvrant destiné à permettre l'ouverture de l'ouvrant comprenant une came mobile en rotation selon un axe de rotation et fixée audit moyen de commande au niveau d'une zone de fixation de sorte à être entraîner en rotation lors du déplacement du moyen de commande,  a lever for opening said opening intended to allow the opening of the opening comprising a cam movable in rotation along an axis of rotation and fixed to said control means at a fastening zone so as to be rotated when moving the control means,
- un moyen de blocage configuré pour prendre une position active de blocage dans laquelle ledit moyen de blocage vient bloquer ladite came et une position de repos dans laquelle ledit moyen de blocage est en contact avec la came sur un profil de came et autorise le mouvement de ladite came,  a blocking means configured to take an active locking position in which said blocking means blocks said cam and a rest position in which said blocking means is in contact with the cam on a cam profile and allows the movement of said cam,
- un moyen de retour élastique configuré pour mettre ledit moyen de blocage en appui sur le profil de came, resilient return means configured to put said locking means into press on the cam profile,

La serrure de la présente invention permet ainsi d'avoir un blocage efficace de la porte en fonction de la force inertielle subie par la serrure par l'intermédiaire de l'accélération subie par le levier d'ouverture. Ainsi, l'ouverture de la serrure de l'invention est évitée pour un mouvement du levier d'ouverture suite à un choc latéral au-delà d'un seuil prédéfini.  The lock of the present invention thus makes it possible to effectively block the door as a function of the inertial force experienced by the lock by means of the acceleration experienced by the opening lever. Thus, the opening of the lock of the invention is avoided for a movement of the opening lever following a side impact beyond a predefined threshold.
Un tel système de blocage est de manière avantageuse indépendant de la géométrie de la porte, n'engendre pas de stress sur la chaîne cinématique, ne nécessite pas de réglage délicat et est indépendant des contraintes géométriques.  Such a locking system is advantageously independent of the geometry of the door, does not generate stress on the kinematic chain, does not require delicate adjustment and is independent of geometric constraints.

The outer opening lever is connected via a cable, such as the Bowden cable, or a rod to the outer handle and the intermediate opening lever is connected via other kinematic elements of the motor vehicle located inside said vehicle, such as the interior handles.
Comme représenté sur la figure 1 , la serrure de l'invention 1 est adaptée pour ouvrir tout type d'ouvrant d'un véhicule automobile, notamment une porte latérale 2.  As shown in Figure 1, the lock of the invention 1 is adapted to open any type of opening of a motor vehicle, including a side door 2.
Sur cette figure 1 est illustré un exemple de choc latéral suivant une direction 3 sensiblement perpendiculaire à l'axe principal 4 du véhicule automobile 5. Le choc peut être engendré par toute sorte d'élément, ici est représenté un véhicule automobile 6. Un tel choc agit sur la poignée dans le sens de l'ouverture de cette dernière selon un mouvement oscillant comprenant une ou plusieurs phases dans lesquelles la tringle ou le câble sont tirés engendrant de ce fait l'ouverture de la serrure 1.  In this figure 1 is illustrated an example of lateral impact in a direction 3 substantially perpendicular to the main axis 4 of the motor vehicle 5. The shock can be generated by any kind of element, here is shown a motor vehicle 6. Such a shock acts on the handle in the direction of the opening of the latter in an oscillating movement comprising one or more phases in which the rod or the cable are pulled thereby causing the opening of the lock 1.
Comme représenté schématiquement sur les figures 2 à 5, ladite serrure 1 comporte un système de blocage comprenant:  As shown diagrammatically in FIGS. 2 to 5, said lock 1 comprises a locking system comprising:
- un moyen de commande 13 mobile, a mobile control means 13,
- un levier d'ouverture 15 dudit ouvrant 2 destiné à permettre l'ouverture de l'ouvrant 2 comprenant une came 17 mobile en rotation autour d'un axe de rotation 18 et fixée audit moyen de commande 13 au niveau d'une zone de fixation 19 de sorte à être entraîner en rotation lors du déplacement du moyen de commande 13; an opening lever 15 of said opening 2 intended to allow the opening of the opening 2 comprising a cam 17 mobile in rotation about an axis of rotation 18 and fixed to said control means 13 at a zone of fastening 19 so as to be dragged into rotation when moving the control means 13;
- un moyen de blocage 21, disposé notamment à proximité de la zone de fixation 19 du moyen de commande, ledit moyen de blocage 21 étant configuré pour prendre une position active de blocage dans laquelle ledit moyen de blocage 21 vient bloquer ladite came 17 et une position de repos dans laquelle ledit moyen de blocage 21 est en contact avec la came 17 et autorise le mouvement de ladite came 17,  a locking means 21 disposed in particular close to the attachment zone 19 of the control means, said locking means 21 being configured to take an active locking position in which said locking means 21 blocks said cam 17 and a rest position in which said locking means 21 is in contact with the cam 17 and allows the movement of said cam 17,
- un moyen de retour élastique 23 configuré pour mettre ledit moyen de blocage 21 en appui sur le profil de came 17,  an elastic return means 23 configured to put said locking means 21 in abutment on the cam profile 17,
le profil de came 25 comprenant une rupture de pente 15a configurée pour amener le moyen de blocage 21 de la position de repos à la position active de blocage lorsque la came 17 pivote autour de son axe 18 vers le sens de l'ouverture de l'ouvrant 2 avec une accélération supérieure à une valeur seuil prédéterminée.  the cam profile 25 comprising a slope break 15a configured to bring the locking means 21 from the rest position to the active locking position when the cam 17 pivots about its axis 18 towards the opening direction of the opening 2 with an acceleration greater than a predetermined threshold value.
Ainsi, grâce à l'invention, le moyen de blocage 21 est déclenché en fonction de la force inertielle ressentie par le levier d'ouverture 15 qui est proportionnelle à l'accélération subie par la came 17. Le déclenchement est contrôlé par la valeur seuil prédéterminée.  Thus, thanks to the invention, the locking means 21 is triggered according to the inertial force felt by the opening lever 15 which is proportional to the acceleration experienced by the cam 17. The trigger is controlled by the threshold value predetermined.
Ladite valeur seuil peut être déterminée par la raideur du moyen de retour élastique 23 et de la masse des cames 17.  Said threshold value may be determined by the stiffness of the elastic return means 23 and the mass of the cams 17.
De manière simple efficace, le blocage du levier d'ouverture 15 est réalisé lors d'un choc exerçant une traction suffisante sur le moyen de commande 13.  In a simple and effective manner, the blocking of the opening lever 15 is achieved during an impact exerting sufficient traction on the control means 13.
Le levier d'ouverture 15 est connecté à la poignée extérieure de l'ouvrant 2 actionnable par un utilisateur via le moyen de commande 13, par exemple une tringle ou, comme ici, un câble, dit « câble Bowden ». Le moyen de commande 13 est mobile entre une position de repos correspondant à la position où aucune action n'est exercée sur ledit moyen de commande 13 et une position active d'ouverture de l'ouvrant correspondant à la position où la poignée extérieure de l'ouvrant 2 est tirée par un utilisateur engendrant une traction sur ledit moyen de commande 13, notamment le câble, engendrant l'ouverture de la serrure 1 de l'invention.  The opening lever 15 is connected to the outer handle of the leaf 2 actuated by a user via the control means 13, for example a rod or, as here, a cable, called "Bowden cable". The control means 13 is movable between a rest position corresponding to the position where no action is exerted on said control means 13 and an active opening position of the opening corresponding to the position where the outer handle of the 2 is pulled by a user generating traction on said control means 13, including the cable, causing the opening of the lock 1 of the invention.
Comme il est visible sur la figure 2, le levier d'ouverture 15 comporte une came 17 mobile en rotation selon un axe de rotation 18, lorsqu'une traction est exercée sur le moyen de commande 13.  As can be seen in FIG. 2, the opening lever 15 comprises a cam 17 rotatable about an axis of rotation 18, when traction is exerted on the control means 13.
Pour ce faire, la came 17 est fixée audit moyen de commande 13 au niveau d'une zone de fixation 19 de sorte à être entraîner en rotation lors du déplacement du moyen de commande 13. La zone de fixation 19 peut être une zone étendue ou une zone ponctuelle. Selon le mode de réalisation illustré sur les figures, la zone de fixation 19 est située sur une excroissance 24 de la came. To do this, the cam 17 is fixed to said control means 13 at a fastening zone 19 so as to be rotated during the movement of the means of control 13. The attachment zone 19 may be an extended zone or a point zone. According to the embodiment illustrated in the figures, the attachment zone 19 is located on a protrusion 24 of the cam.
Selon le mode de réalisation représenté sur les figures, le moyen de commande 13 est inséré dans un logement 26 traversant l'excroissance 24. L'extrémité 27 ainsi insérée dans l'excroissance 24 ressort du logement 26 selon un axe sensiblement colinéaire à l'axe de rotation 18 de la came. Ainsi lorsqu'une traction est exercée sur le moyen de commande 13 dans le sens de l'ouverture de l'ouvrant 2, la came 17 via la zone de fixation 19 est entraînée en rotation selon son axe de rotation 18.  According to the embodiment shown in the figures, the control means 13 is inserted into a housing 26 passing through the protrusion 24. The end 27 thus inserted into the protrusion 24 leaves the housing 26 along an axis substantially co-linear with the rotation axis 18 of the cam. Thus when traction is exerted on the control means 13 in the opening direction of the opening 2, the cam 17 via the attachment zone 19 is rotated along its axis of rotation 18.
La came 17 comporte également un profil de came 25 configuré pour amener le moyen de blocage 21 de la position de repos à la position active de blocage lorsque la came 17 pivote autour de son axe de rotation 18 vers le sens de l'ouverture de l'ouvrant 2.  The cam 17 also comprises a cam profile 25 configured to bring the locking means 21 from the rest position to the active locking position when the cam 17 pivots about its axis of rotation 18 toward the opening direction of the cam. opening 2.
Le profil de came 25 peut comporter une rupture de pente afin de permettre le passage de la position de blocage à la position de repos du moyen de blocage 21. On entend ici par « rupture de pente », un profil de came présentant une surface avec au moins deux plans directeurs formant un angle non nul.  The cam profile 25 may comprise a slope break in order to allow the blocking position to pass to the rest position of the blocking means. In this case, the term "slope break" means a cam profile having a surface with at least two planes forming a non-zero angle.
Selon le mode de réalisation représenté sur les figures, le profil de came 25 présente une forme sensiblement concave par rapport au centre de la came 17.  According to the embodiment shown in the figures, the cam profile 25 has a substantially concave shape with respect to the center of the cam 17.
La came 17 peut également comporter un renfoncement 31 apte à recevoir une partie 33 du moyen de blocage. Le renfoncement 33 peut être formé en continuité avec le profil de came 25 ce qui permet de simplifier la fabrication de la serrure de l'invention.  The cam 17 may also include a recess 31 adapted to receive a portion 33 of the locking means. The recess 33 may be formed in continuity with the cam profile 25 which simplifies the manufacture of the lock of the invention.
Le moyen de blocage 21 est disposé à proximité de la zone de fixation 19 du moyen de commande, ledit moyen de blocage 21 étant configuré pour prendre une position active de blocage dans laquelle ledit moyen de blocage 21 vient bloquer ladite came 17 et une position de repos dans laquelle ledit moyen de blocage 21 est en contact avec la came 17 et autorise le mouvement de ladite came 17. Le moyen de blocage 21 peut être mobile en rotation selon un axe de rotation 38 sensiblement colinéaire à l'axe de rotation 18 de la came.  The locking means 21 is disposed near the attachment zone 19 of the control means, said locking means 21 being configured to take an active locking position in which said locking means 21 blocks said cam 17 and a position of rest in which said locking means 21 is in contact with the cam 17 and allows the movement of said cam 17. The locking means 21 can be rotatable about an axis of rotation 38 substantially collinear with the axis of rotation 18 of drug.
Le moyen de blocage 21 peut comporter une excroissance 41 configurée pour suivre le profil de came 25 lorsque le moyen de blocage 21 est la position de repos et au début du passage de la position de repos à la position active de blocage sous l'effet d'une accélération subie par le levier d'ouverture 15 supérieure à la valeur seuil prédéterminée. L'excroissance 41 peut être avantageusement élastique afin de mieux suivre sur le contour du profil de came 25 en position de repos et au début du passage de la position de repos à la position active de blocage. The blocking means 21 may comprise a protrusion 41 configured to follow the cam profile 25 when the locking means 21 is the rest position and at the beginning of the transition from the rest position to the active locking position under the effect of an acceleration experienced by the opening lever 15 greater than the predetermined threshold value. The protrusion 41 may advantageously be elastic so as to better follow the contour of the cam profile 25 in the rest position and at the beginning of the transition from the rest position to the active locking position.
Le moyen de blocage peut être réalisé de manière monobloc ou non. Ainsi, l'excroissance peut être réalisée de matière avec le moyen de blocage ou rapporté sur ce dernier.  The locking means may be made integrally or not. Thus, the protrusion can be made of material with the locking means or attached to the latter.
Le moyen de blocage 21 est réalisé dans un matériau adapté, tel que les matières plastiques, l'acier ou le zamak®.  The locking means 21 is made of a suitable material, such as plastics, steel or zamak®.
Le moyen de blocage 21 est associé au moyen de retour élastique 23 configuré pour mettre ledit moyen de blocage 21 en appui sur le profil de came 17 afin de garantir un contact permanent entre le moyen de blocage et la came 11 en position de repos. Le moyen de retour élastique 23 peut être un ressort travaillant en torsion, notamment un ressort en spirale dont l'axe de rotation est sensiblement confondu avec l'axe de rotation 38 du moyen de blocage ou peut être sensiblement déporté par rapport audit axe 38.  The locking means 21 is associated with the elastic return means 23 configured to put said locking means 21 in abutment on the cam profile 17 in order to guarantee permanent contact between the locking means and the cam 11 in the rest position. The elastic return means 23 may be a torsion spring, in particular a spiral spring whose axis of rotation is substantially coincident with the axis of rotation 38 of the locking means or may be substantially offset with respect to said axis 38.
Le ressort en spirale peut comporter une première extrémité 23 a fixée à un élément fixe 61 de la serrure et une seconde extrémité 23b fixée au moyen de blocage 21 de sorte à entraîner le moyen de blocage en appui sur le profil de came 25.  The spiral spring may comprise a first end 23a fixed to a fixed element 61 of the lock and a second end 23b fixed to the locking means 21 so as to cause the locking means to bear on the cam profile 25.
Pour ce faire, l'extrémité 23b peut traverser une cavité ménagée dans ou contre la surface du moyen de blocage 21.  To do this, the end 23b can pass through a cavity formed in or against the surface of the locking means 21.
La structure fixe de la serrure 1 de l'invention peut comporter une butée élastique 51 configurée pour recevoir une partie 53 du moyen de blocage en position de blocage. La butée élastique permet alors le maintien du moyen de blocage en position bloquée.  The fixed structure of the lock 1 of the invention may comprise a resilient stop 51 configured to receive a portion 53 of the locking means in the locking position. The elastic stop then makes it possible to hold the locking means in the locked position.
Ladite butée élastique 51 est configurée pour se déformer afin de permettre le retour du moyen de blocage 21 de la position de blocage à la position de repos.  Said elastic stop 51 is configured to deform in order to allow the return of the locking means 21 from the locking position to the rest position.
Afin de déformer la butée 51 pour passer le moyen de blocage 21 de la position de blocage à la position de repos, la contrainte appliquée sur ladite butée 51 doit être supérieure à une valeur seuil prédéfinie. Ladite contrainte peut correspondre à une force de traction exercée sur le moyen de commande 13.  In order to deform the stop 51 to pass the blocking means 21 from the blocking position to the rest position, the stress applied on said stop 51 must be greater than a predefined threshold value. Said stress may correspond to a traction force exerted on the control means 13.
Ainsi, on prévient le déblocage de la came 17 et donc l'ouverture de l'ouvrant 2 durant les phases d'oscillation.  Thus, it prevents the release of the cam 17 and thus the opening of the opening 2 during the oscillation phases.
La butée élastique 51 est configurée pour ne pas gêner le déplacement de la came 17 et du moyen de blocage 21 en position de repos et en position de blocage de la came 11. La butée élastique est réalisée dans un matériau flexible adapté, tel que les matières plastiques, notamment une résine acétal, un polyamide. The elastic stop 51 is configured so as not to hinder the displacement of the cam 17 and the locking means 21 in the rest position and in the locked position of the cam 11. The elastic abutment is made of a suitable flexible material, such as plastics, especially an acetal resin, a polyamide.
Selon une variante non représentée, le moyen de blocage peut être bloqué en position de blocage directement par un élément de la came qui peut bloquer le moyen de blocage dans la position de blocage et peut se déformer élastiquement lorsque la came pivote autour de son axe dans le sens de l'ouverture de l'ouvrant afin de libérer le moyen de blocage vers la position de repos.  According to a variant not shown, the locking means can be locked in the locking position directly by a member of the cam which can lock the locking means in the locking position and can deform elastically when the cam pivots about its axis in the opening direction of the opening to release the locking means to the rest position.
En position de repos, le moyen de blocage 12 est en contact permanent avec la came de sorte que la rotation de la came dans le sens de l'ouverture de l'ouvrant comprime le moyen de retour élastique sans rompre le contact entre la came 17 et le moyen de blocage 21. Ceci permet de mettre en léger mouvement le moyen de blocage en position de repos de sorte à éviter tout grippage du moyen de retour élastique et du moyen de blocage si la position de blocage n'est pas activée durant une grande période de temps.  In the rest position, the locking means 12 is in permanent contact with the cam so that the rotation of the cam in the opening direction of the leaf compresses the elastic return means without breaking the contact between the cam 17 and the locking means 21. This makes it possible to put in slight movement the locking means in the rest position so as to prevent seizing of the elastic return means and the locking means if the locking position is not activated during a great period of time.
La cinématique suivant un choc latéral, par exemple celui suivant la direction 3, va être maintenant décrite plus en détail, à l'aide des figures 3a à 3f.  The kinematics following a side impact, for example that along the direction 3, will now be described in more detail, using FIGS. 3a to 3f.
Dans le mode de réalisation représenté sur la figure 3a, le moyen de blocage 21 et le moyen de commande 13 sont tous les deux en position de repos. Dans cette position et en l'absence de choc latéral, l'excroissance 41 du moyen de blocage est en appui constant sur le profil de came 25 grâce au moyen de retour élastique 23.  In the embodiment shown in FIG. 3a, the locking means 21 and the control means 13 are both in the rest position. In this position and in the absence of lateral impact, the protrusion 41 of the blocking means is in constant abutment on the cam profile 25 by means of resilient return means 23.
Dans le mode de réalisation représenté sur la figure 3b, lors d'un choc latéral par exemple, une traction est exercée sur le moyen de commande 13 engendrant la rotation de la came 11 autour de son axe de rotation 18 via la zone de fixation 19.  In the embodiment shown in FIG. 3b, during a lateral impact, for example, a traction is exerted on the control means 13 generating the rotation of the cam 11 around its axis of rotation 18 via the fastening zone 19 .
Lorsque la traction est exercée sur le moyen de commande 13 inférieure à une valeur seuil, correspondant à une traction normale d'un utilisateur, le moyen de blocage 21 reste en contact permanent sur la came par l'excroissance 41 qui suit le profil de came 25 et par le moyen de retour élastique 23.  When the traction is exerted on the control means 13 below a threshold value, corresponding to a normal traction of a user, the locking means 21 remains in permanent contact on the cam by the protrusion 41 which follows the cam profile 25 and by the elastic return means 23.
Comme représenté sur la figure 3 c, si la valeur de la traction exercée sur le moyen de commande 13 vers le sens de l'ouverture de l'ouvrant, est supérieure à la valeur seuil, l'excroissance 41 suit de manière plus rapide le profil de came 25 si bien que lorsque l'excroissance 41 arrive au niveau de la rupture de pente du profil de came 25, l'excroissance 41 cesse d'être en contact avec la surface de la came 17.  As shown in FIG. 3c, if the value of the traction exerted on the control means 13 towards the direction of opening of the opening leaf is greater than the threshold value, the protrusion 41 follows more rapidly the cam profile 25 so that when the protrusion 41 reaches the level of the slope break of the cam profile 25, the protrusion 41 ceases to be in contact with the surface of the cam 17.
Le moyen de retour élastique 23 présente une raideur insuffisante pour ramener le moyen de blocage 21 en contact sur la came 11. Du fait de l'accélération que subie le moyen de blocage 21 lors de cette rotation, ce dernier finit sa rotation autour de son axe de rotation 38 et la partie 33 du moyen de blocage vient se loger dans le renfoncement 31 de la came 11 (voir figure 3d). The resilient return means 23 has insufficient stiffness to bring the locking means 21 in contact on the cam 11. Due to the acceleration experienced by the locking means 21 during this rotation, the latter ends its rotation about its axis of rotation 38 and the portion 33 of the locking means comes to fit in the recess 31 of the cam 11 (see Figure 3d).
Le moyen de blocage 21 ne peut plus alors revenir à sa position de repos du fait de la butée élastique 51 qui bloque ledit moyen de blocage 21 dans la position de blocage.  The locking means 21 can not then return to its rest position due to the elastic stop 51 which blocks said locking means 21 in the locking position.
Si le choc subi par l'ouvrant 2 induit des oscillations tendant à faire pivoter came 11 dans le sens de l'ouverture de l'ouvrant 2, ces dernières ont typiquement une intensité inférieure à la raideur de la butée élastique 51 , si bien que la butée élastique ne se déforme pas et la rotation de la came 17 reste bloquer par le moyen de blocage.  If the shock suffered by the opening 2 induces oscillations tending to pivot cam 11 in the opening direction of the opening 2, the latter typically have a lower intensity than the stiffness of the elastic abutment 51, so that the elastic stop does not deform and the rotation of the cam 17 remains blocked by the blocking means.
Afin de dégager le moyen de blocage 12 de sa position de blocage et le remettre en position de repos, une traction est imposée au moyen de commande 13 de sorte à faire pivoter la came 17 avec une force supérieure à la raideur de la butée élastique 51 si bien que cette dernière se déforme pour libérer le moyen de blocage 21 (voir figure 3 e).  In order to release the blocking means 12 from its blocking position and return it to the rest position, traction is imposed on the control means 13 so as to rotate the cam 17 with a force greater than the stiffness of the elastic stop 51 so that the latter is deformed to release the locking means 21 (see Figure 3 e).
Comme visible sur la figure 3f, le moyen de retour élastiques 23 rappelle le moyen de blocage 21 vers la position de repos, en appui sur le profil de came 25.  As can be seen in FIG. 3f, the elastic return means 23 recalls the locking means 21 towards the rest position, resting on the cam profile 25.
Ainsi de manière avantageuse, la serrure de l'invention présente un moyen de blocage actionné par la vitesse de traction du moyen de commande, ici le câble Bowden, tout en comportant une phase dans laquelle on déclenche l'envolée du moyen de blocage vers sa position de blocage sous l'impulsion d'un effort inertiel. Grâce à l'invention, il existe un principe de blocage, qui empêche l'ouverture par blocage du levier d'ouverture, un principe de remise en position de repos et du principe de mise en torsion ou en moment pour éviter le grippage.  Thus advantageously, the lock of the invention has a locking means actuated by the traction speed of the control means, here the Bowden cable, while having a phase in which the flight of the locking means is triggered towards its blocking position under the impulse of an inertial effort. Thanks to the invention, there is a blocking principle, which prevents opening by locking the opening lever, a principle of restoring the rest position and the principle of torsion or moment to avoid seizure.
La serrure de l'invention présente les avantages suivants :  The lock of the invention has the following advantages:
- le blocage de l'ouverture en cas de traction sur le câble de levier d'ouverture lors d'un choc inertiel avec un dispositif de blocage indépendant de l'environnement de la serrure,- the locking of the opening in case of traction on the opening lever cable during an inertial shock with a locking device independent of the environment of the lock,
- le blocage de la chaîne cinématique de la serrure réalisé au sein de la serrure en évitant toute interaction avec des éléments présents dans l'ouvrant, - Locking the kinematic chain of the lock made within the lock by avoiding any interaction with elements present in the opening,
- le déclenchement sous l'effet inertiel provenant d'un choc ou non,  - the triggering under the inertial effect resulting from an impact or not,
- le déclenchement s'opérant à partir d'un seuil d'effort inertiel qui est déterminé par la rupture de pente du profil de came et de la raideur choisi du moyen de retour élastique du moyen de blocage, - le positionnement du moyen de blocage présente une haute tolérance car le blocage se fait par contact sur des zones ce qui permet de s'affranchir des jeux de fabrication, the triggering taking place from an inertial force threshold which is determined by the slope break of the cam profile and the stiffness chosen for the elastic return means of the locking means, - The positioning of the locking means has a high tolerance because the blocking is done by contact on areas which eliminates manufacturing games,
- la remise en positon de repos peut s'effectuer de manière simple et fiable par un effort supplémentaire réalisable par un utilisateur,  - Restoring rest position can be performed simply and reliably by additional effort achievable by a user,
- le volume du support sur lequel est fixé le moyen de blocage est réduit ce qui permet également une réduction du coût de fabrication. - The volume of the support on which is fixed the locking means is reduced which also allows a reduction in manufacturing cost.
