Description

DISPOSITIF DE VERROUILLAGE D'UN CAPOT DE VEHICULE AUTOMOBILE L'invention concerne les dispositifs de verrouillage pour capot de véhicule automobile et notamment ceux du type comportant une serrure dont l'ouverture s'effectue en deux temps. Dans un premier temps, la serrure est déverrouillée à partir d'un mécanisme commandé à distance depuis l'intérieur du véhicule puis l'ouverture est effectuée manuellement par actionnement du crochet de sécurité. The invention relates to locking devices for a hood of a motor vehicle and in particular those of the type comprising a lock which is opened in two stages. Initially, the lock is unlocked from a remotely controlled mechanism from inside the vehicle and the opening is performed manually by actuating the safety hook.

Pour ouvrir la serrure, il faut donc glisser la main entre le capot et la calandre de pare-choc pour actionner le crochet de sécurité et libérer le capot. On conçoit que l'accès au crochet est particulièrement difficile, l'utilisateur doit glisser sa main dans un intervalle très réduit 1s entre le capot et la calandre et la manipulation se fait ainsi "en aveugle". Le but de l'invention est donc de proposer un système d'ouverture de capot permettant un accès direct et visuel au crochet de sécurité. 20 A cet effet, la présente invention a pour objet un dispositif de verrouillage de capot de véhicule automobile du type comportant une serrure comprenant un pêne lié à la structure inférieure du véhicule et une gâche pratiquée dans une paroi du capot en regard de l'extrémité du pêne. 25 Le dispositif de verrouillage comporte, en outre et selon les enseignements de l'invention, une palette articulée, mobile en rotation, autour d'un axe transversal perpendiculaire à l'axe du capot monté dans un support fixé sur la structure inférieure du véhicule et un organe de transmission d'effort relié, d'une part 30 à la palette et d'autre part au pêne pour agir en traction sur dudit pêne lorsque la palette est basculée autour de son axe. To open the lock, you must slide your hand between the hood and the bumper grille to activate the safety hook and release the hood. It is understood that the access to the hook is particularly difficult, the user must slide his hand in a very short interval 1s between the hood and the grille and the manipulation is thus "blind". The object of the invention is therefore to provide a hood opening system allowing direct and visual access to the safety hook. To this end, the present invention relates to a motor vehicle hood locking device of the type comprising a lock comprising a bolt connected to the lower structure of the vehicle and a strike in a wall of the hood facing the end. bolt. The locking device further comprises, and according to the teachings of the invention, an articulated pallet movable in rotation about a transverse axis perpendicular to the axis of the hood mounted in a support fixed to the lower structure of the vehicle. and a force transmission member connected on the one hand to the pallet and on the other hand to the bolt to act in tension on said bolt when the pallet is tilted about its axis.

Selon d'autres caractéristiques avantageuses de l'invention : - la face extérieure de la palette porte un emblème. - En variante, la palette est elle-même en forme d'emblème. - Dans un mode de réalisation, le pêne est formé d'un crochet articulé autour d'un axe transversal fixé sur une platine perpendiculairement à l'axe du capot. - Avantageusement, l'organe de transmission d'effort est constitué d'une tirette souple. - Dans un autre mode de réalisation, le pêne est en forme de io doigt maintenu engagé dans la gâche par un dispositif élastique libéré par la manoeuvre de la palette. - Selon un mode de réalisation, la palette est logée au moins en partie dans une découpe formée dans le capot. D'autres caractéristiques et avantages de l'invention is apparaîtront clairement à la lecture de la description ci-après, donnée à titre indicatif en référence aux dessins annexés dans lesquels : La figure 1 est une vue d'un capot muni d'un système d'ouverture selon l'invention, 20 La figure 2 est une vue en coupe selon l'axe XX' de la figure 1 au droit du système d'ouverture, en position fermée du capot et, La figure 3 est une vue analogue à celle de la figure 2, en position ouverte du capot. 25 Sur la figure 1 est représenté un capot 1 de véhicule automobile dont le bord avant est muni d'une découpe médiane 2. Cette découpe est destinée à recevoir une plaque en forme de palette 3. Avantageusement, cette palette a également des 30 fonctions décoratives. Sa face extérieure porte, par exemple, un emblème 4 qui peut-être, comme cela est bien connu, celui du constructeur et/ou celui du modèle du véhicule. En variante, la palette elle-même peut être façonnée en forme d'emblème. According to other advantageous features of the invention: the outer face of the pallet bears an emblem. As a variant, the pallet is itself in the form of an emblem. In one embodiment, the bolt is formed of a hook hinged about a transverse axis fixed on a plate perpendicular to the axis of the cap. Advantageously, the force transmission member consists of a flexible zipper. In another embodiment, the bolt is in the form of a finger held engaged in the striker by an elastic device released by the operation of the pallet. According to one embodiment, the pallet is housed at least partly in a cutout formed in the cover. Other features and advantages of the invention will become clear from reading the description below, given for information with reference to the accompanying drawings in which: FIG. 1 is a view of a hood equipped with a system 2 is a sectional view along the axis XX 'of FIG. 1 to the right of the opening system, in the closed position of the hood, and FIG. 3 is a view similar to FIG. that of Figure 2, in the open position of the cover. FIG. 1 shows a hood 1 of a motor vehicle whose front edge is provided with a central cut-out 2. This cutout is intended to receive a pallet-shaped plate 3. Advantageously, this pallet also has decorative functions. . Its outer face bears, for example, an emblem 4 which may be, as is well known, that of the manufacturer and / or the model of the vehicle. Alternatively, the pallet itself can be shaped emblem.

La palette 3 est munie sur sa face intérieure d'une patte 5 dans laquelle est engagée un axe 6 perpendiculaire à l'axe XX' du capot. L'axe 6 est monté dans un support 7 fixé sur la structure inférieure 8 du véhicule de sorte que la palette 3 est articulée, mobile en rotation, autour de cet axe. io Une serrure est fixée sur la structure 8 du véhicule en regard de la palette 3. Elle comporte une platine 9 sur laquelle est monté un pêne en forme de crochet 10. Ledit pêne est articulé autour d'un axe transversal 110 fixé sur la platine 9 perpendiculairement à l'axe XX' du capot. La rotation du pêne is est bloquée en position verrouillée du capot au moyen d"un mécanisme (non représenté), commandé depuis l'intérieur du véhicule. Une gâche 13 est pratiquée dans une paroi interne 14 du capot 1 en regard de l'extrémité 11 du pêne 10, de façon que 20 cette extrémité soit engagée dans l'ouverture de la gâche en position de fermeture du capot. Un organe de transmission d'effort, par exemple une tirette 12, est fixé d'une part sur le pêne 10 et d'autre part sur la face intérieure de la palette 3, au dessous du point d'articulation de 25 l'axe 6. La tirette est avantageusement un élément souple, de type fils, câble, sangle ou analogue afin de ne pas ajouter de point dur à cet emplacement pour respecter les normes de sécurité en cas de choc, notamment avec un piéton. The pallet 3 is provided on its inner face with a lug 5 in which is engaged an axis 6 perpendicular to the axis XX 'of the hood. The axis 6 is mounted in a support 7 fixed on the lower structure 8 of the vehicle so that the pallet 3 is hinged, rotatable about this axis. A lock is fixed on the structure 8 of the vehicle facing the pallet 3. It comprises a plate 9 on which is mounted a hook-shaped bolt 10. Said bolt is articulated about a transverse axis 110 fixed on the plate 9 perpendicular to the axis XX 'of the hood. The rotation of the bolt is locked in the locked position of the cover by means of a mechanism (not shown) controlled from inside the vehicle A strike 13 is formed in an inner wall 14 of the cover 1 opposite the end 11 of the bolt 10, so that this end is engaged in the opening of the striker in the closed position of the cover.A force transmission member, for example a pull tab 12, is fixed on the one hand on the bolt 10 and on the other hand on the inner face of the pallet 3, below the point of articulation of the axis 6. The zipper is advantageously a flexible element, wire, cable, strap or the like so as not to add hard point at this location to meet the safety standards in case of impact, especially with a pedestrian.

Le fonctionnement du système se déduit logiquement de la description que l'on vient de faire. Lorsque la rotation du pêne 10 a été débloquée de l'intérieur du véhicule, il suffit de lever la palette 3 dans le sens de la flèche F. La tirette 12, entraînée par ce mouvement, exerce une traction sur le pêne 10 qui tourne autour de son point d'articulation 110 sur la platine 9. L'extrémité 11 du pêne se désengage alors de la gâche 13 solidaire du capot, libérant celui-ci. io A l'inverse, pour verrouiller le capot il suffit d'exercer sur celui-ci un effort dans le sens vertical, selon la flèche F1, le bord 15 de la découpe 2 vient alors en appui sur la patte 5 portée par la palette 3 qui bascule sur son axe. Le pêne 10 qui n'est plus maintenu en position relevée par la tirette 12, tourne autour de is son axe pour venir s'engager dans la gâche 13 du capot lequel est ainsi de nouveau verrouillé. Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire. On peut, par exemple, utiliser un pêne en forme de doigt, maintenu engagé dans la 20 gâche par un dispositif élastique libéré par la manoeuvre de la palette. Le système que l'on vient de décrire est simple à réaliser. Il est implanté dans une zone particulièrement repérable et facile à atteindre. En outre la manoeuvre est facilitée par la 25 démultiplication des efforts obtenue par l'effet de bras de levier qui s'exerce sur l'axe d'articulation du pêne de la serrure pour entraîner sa rotation. The operation of the system is logically deduced from the description just made. When the rotation of the bolt 10 has been released from inside the vehicle, it is sufficient to lift the pallet 3 in the direction of the arrow F. The pull tab 12, driven by this movement, exerts a pull on the bolt 10 which rotates around its point of articulation 110 on the plate 9. The end 11 of the bolt then disengages the keeper 13 secured to the cover, releasing it. Conversely, to lock the hood simply exert on it a force in the vertical direction, according to the arrow F1, the edge 15 of the blank 2 then bears on the leg 5 carried by the pallet 3 that rocks on its axis. The bolt 10 which is no longer maintained in the raised position by the pull tab 12, rotates about is its axis to engage in the striker 13 of the cover which is thus locked again. Of course, the invention is not limited to the embodiment that has just been described. One can, for example, use a finger-shaped bolt held engaged in the keeper by an elastic device released by the operation of the pallet. The system just described is simple to perform. It is located in a particularly identifiable area and easy to reach. In addition, the maneuver is facilitated by the reduction of the forces obtained by the leverage effect exerted on the axis of articulation of the bolt of the lock to cause its rotation.
