Description

Structure pour ouvrant de véhicule comprenant des moyens de positionnement et de fixation d'une serrure sur un panneau de l' ouvrant Structure for a vehicle opening comprising means for positioning and fixing a lock on a panel of the opening
L' invention se rapporte à une structure pour ouvrant de véhicule, et en particulier pour ouvrant de véhicule automobile . De manière classique en soi, l'ouvrant de véhicule comporte un panneau interne, appelé caisson, lequel est agencé avec un panneau externe pour constituer un panneau d'ouvrant. Une serrure d'ouvrant est fixée à l'intérieur du panneau interne au moyen d'une platine (ou plaque de serrure) . La serrure comporte un pêne destiné à coopérer avec un fil de gâche fixé à la structure de caisse du véhicule. La fixation de la platine sur le panneau interne est réalisée au moyen de vis de fixation. The invention relates to a structure for opening a vehicle, and in particular for opening a motor vehicle. In a conventional manner, the vehicle opening comprises an inner panel, called box, which is arranged with an outer panel to form an opening panel. A sash lock is fixed inside the inner panel by means of a plate (or lock plate). The lock comprises a bolt for cooperating with a strike wire attached to the body structure of the vehicle. The fixing of the plate on the inner panel is achieved by means of fixing screws.
Lors du mouvement de fermeture de l'ouvrant, un fil de gâche rentre en contact avec le pêne et force sur ce dernier pour le déplacer. Lorsque le mouvement arrive en fin de fermeture, le fil de gâche dépasse le pêne lequel reprend sa position, emprisonnant alors le fil de gâche. Ce mouvement de fermeture étant effectué plusieurs milliers de fois pendant la durée de vie du véhicule, il est nécessaire d'assurer une résistance aux mouvements répétés de fermeture. A cet égard, le panneau interne comporte une zone renforcée au moyen d'un élément de renfort se présentant sous la forme d'une plaque fixée à l'intérieur du panneau interne et sur laquelle la platine de serrure est fixée. Une telle structure est décrite dans la demande de brevet français FR2434725.  During the closing movement of the opening, a striker wire comes into contact with the bolt and forces on the latter to move it. When the movement arrives at the end of closing, the striker wire exceeds the bolt which resumes its position, then trapping the striker wire. This closing movement being performed several thousand times during the life of the vehicle, it is necessary to ensure resistance to repeated closing movements. In this regard, the inner panel comprises a reinforced zone by means of a reinforcing element in the form of a plate fixed inside the inner panel and on which the lock plate is fixed. Such a structure is described in the French patent application FR2434725.
Afin de permettre un positionnement correct de la platine de serrure sur la zone renforcée, l'élément de renfort présente des déformations coniques ménagées autour des trous de passage des vis de fixation, sur la face de l'élément de renfort recevant la platine de serrure, et aptes à s' emboîter dans les déformations coniques femelles ménagées dans la platine. La présence des déformations coniques permet de guider et de centrer la platine de serrure lors de son montage sur la zone renforcée du panneau interne . In order to allow correct positioning of the lock plate on the reinforced zone, the reinforcing element has conical deformations formed around the holes for the fixing screws, on the face of the reinforcing element receiving the lock plate, and able to fit into the female conical deformations formed in the plate. The presence of conical deformations makes it possible to guide and center the lock plate when it is mounted on the reinforced zone of the inner panel.
Un tel agencement présente toutefois un certain nombre d' inconvénients .  Such an arrangement, however, has a number of disadvantages.
En premier lieu, un tel agencement induit un problème d' hyperstatisme lié à l'assemblage de la platine de serrure et de l'élément de renfort par 1 ' emboîtement des déformations coniques prévues sur chacun des deux éléments. Ce problème d' hyperstatisme s'avère d'autant plus gênant que l'élément de renfort présente une certaine épaisseur.  In the first place, such an arrangement induces a problem of hyperstatism related to the assembly of the lock plate and the reinforcing element by one interlocking of the conical deformations provided on each of the two elements. This problem of hyperstatism is all the more troublesome as the reinforcing element has a certain thickness.
En second lieu, un tel agencement impose une surface de contact faible entre la platine de serrure et l'élément de renfort du fait des déformations coniques mises en œuvre pour permettre le montage de la platine sur l'élément de renfort et des espaces nécessaires pour le passage du fluide de cataphorèse. Il en résulte donc une mauvaise interface en termes de géométrie et de contact entre les trois pièces principales intervenant dans la fixation de la serrure sur le panneau interne, à savoir le panneau interne lui-même, l'élément de renfort et la platine de serrure sur laquelle est montée la serrure.  Secondly, such an arrangement imposes a weak contact surface between the lock plate and the reinforcing element because of the conical deformations implemented to allow the mounting of the plate on the reinforcing element and the spaces necessary for the passage of the cataphoresis fluid. This therefore results in a bad interface in terms of geometry and contact between the three main parts involved in fixing the lock on the inner panel, namely the inner panel itself, the reinforcing element and the lock plate on which is mounted the lock.
Ce problème d'interface est d'autant plus gênant qu'il génère en outre des instabilités de montage se répercutant sur la prestation ouverture et fermeture de l'ouvrant.  This interface problem is all the more troublesome as it also generates mounting instabilities that affect the opening and closing of the opening.
Par ailleurs, un tel agencement impose un certain ordre de vissage de la platine de serrure sur le panneau interne. Il a en effet été constaté que l'ordre de vissage avait une influence directe sur la surface de contact entre la platine de serrure et l'élément de renfort et donc sur la qualité de 1 ' interface .  Moreover, such an arrangement imposes a certain order of screwing the lock plate on the inner panel. It has indeed been found that the screwing order had a direct influence on the contact surface between the lock plate and the reinforcing element and thus on the quality of the interface.
L' invention vise à remédier à ces problèmes en proposant une structure pour ouvrant de véhicule permettant d'améliorer l'interface entre la platine de serrure, l'élément de renfort et le panneau interne en termes de surface d'appui et de géométrie, tout en assurant un positionnement et une fixation satisfaisants de la plaque de serrure sur le panneau interne, de sorte à renforcer la tenue mécanique de la serrure lors du claquage à la fermeture de l'ouvrant. The aim of the invention is to remedy these problems by providing a vehicle opening structure for improving the interface between the lock plate, the reinforcing member and the inner panel in terms of bearing surface and geometry, while ensuring satisfactory positioning and attachment of the lock plate on the inner panel, so as to strengthen the mechanical strength of the lock during the breakdown when closing the door.
A cet effet, et selon un premier aspect, l'invention propose une structure pour ouvrant de véhicule, en particulier de véhicule automobile, comprenant un panneau destiné à former un caisson d'ouvrant, une plaque de renfort en appui sur une paroi intérieure du panneau, la plaque et le panneau formant une zone renforcée présentant des trous traversant la plaque et le panneau, et des moyens de positionnement et de fixation d'une plaque de serrure sur la zone renforcée, les moyens de fixation comprenant des tiges de fixation traversant chacune un des trous cylindriques, chacune des tiges étant pourvue d'une portée cylindrique de centrage coopérant avec au moins l'un des trous cylindriques .  For this purpose, and according to a first aspect, the invention proposes a structure for opening a vehicle, in particular a motor vehicle, comprising a panel intended to form an opening box, a reinforcing plate resting on an inner wall of the panel, the plate and the panel forming a reinforced zone having holes through the plate and the panel, and means for positioning and fixing a lock plate on the reinforced zone, the fastening means comprising through fastening rods each one of the cylindrical holes, each of the rods being provided with a cylindrical centering bearing cooperating with at least one of the cylindrical holes.
Ainsi, la présence d'une portée cylindrique sur les tiges de fixation traversant la plaque de renfort et le panneau, permet d'assurer avec le trou de fixation associé de forme complémentaire à celle de la portée cylindrique un centrage de la tige de fixation avec le trou. En d'autres termes, cet agencement permet de disposer la tige de fixation coaxialement avec le trou de fixation associé.  Thus, the presence of a cylindrical surface on the fastening rods passing through the reinforcing plate and the panel makes it possible to ensure, with the associated fixing hole of a shape complementary to that of the cylindrical seat, a centering of the fixing rod with the hole. In other words, this arrangement makes it possible to arrange the fixing rod coaxially with the associated fixing hole.
Avantageusement, la portée cylindrique de centrage présente une hauteur supérieure à l'épaisseur de la zone renforcée. Cela permet ainsi de favoriser un centrage automatique de la plaque sur la zone renforcée et ainsi de compenser les éventuels jeux présents entre les tiges de fixation et les trous de fixation traversant ménagés dans la plaque de serrure et aptes à recevoir une tige de fixation.  Advantageously, the cylindrical centering surface has a height greater than the thickness of the reinforced zone. This thus makes it possible to promote automatic centering of the plate on the reinforced zone and thus to compensate any gaps present between the fixing rods and the through-fixing holes formed in the lock plate and able to receive a fixing rod.
Avantageusement, l'un des trous cylindriques présente une forme oblongue permettant le déplacement de la portée cylindrique de centrage le long du trou cylindrique. Cela permet ainsi d'ajuster la position de l'une au moins des tiges de fixation sur la zone renforcée de sorte à rattraper les éventuels écarts de positionnement intervenant entre les trous de fixation de la zones renforcée et les trous de fixation de la plaque de serrure. Advantageously, one of the cylindrical holes presents an oblong shape for moving the centering cylindrical bearing surface along the cylindrical hole. This thus makes it possible to adjust the position of at least one of the fixing rods on the reinforced zone so as to make up for any positioning differences occurring between the fixing holes of the reinforced zone and the holes for fixing the plate. lock.
Avantageusement, l'un des trous cylindriques présente un diamètre supérieur à celui de la portée cylindrique de centrage de sorte à n'intervenir que dans la fixation de la plaque de serrure sur la zone renforcée.  Advantageously, one of the cylindrical holes has a diameter greater than that of the cylindrical centering surface so as to intervene only in the fixing of the lock plate on the reinforced zone.
La disposition, la forme et les dimensions des trous cylindriques de la zone renforcée et de la configuration épaulée des tiges de fixation permettent d'assurer un positionnement correct et précis des tiges de fixation par rapport à la zone renforcée, et donc d'assurer un maintien satisfaisant et stable de la plaque de serrure sur la zone renforcée .  The arrangement, the shape and the dimensions of the cylindrical holes of the reinforced zone and the shouldered configuration of the fixing rods make it possible to ensure a correct and precise positioning of the fixing rods with respect to the reinforced zone, and thus to ensure a satisfactory and stable maintenance of the lock plate on the reinforced area.
Afin d'améliorer la stabilité du montage plaque de serrure et panneau, la zone renforcée comporte des portions de surface embouties définissant des surfaces de contact entre la plaque de renfort et le panneau.  In order to improve the stability of the lock plate and panel mount, the reinforced area has embossed surface portions defining contact surfaces between the backing plate and the panel.
Avantageusement, les portions de surface embouties s' étendent, en tout ou partie, autour des trous cylindriques.  Advantageously, the stamped surface portions extend, in all or part, around the cylindrical holes.
Selon une configuration avantageuse, la zone renforcée, pourvue de trois trous cylindriques, comporte une première portion de surface emboutie formée sur le panneau et s' étendant entre deux des trois trous cylindriques et une deuxième portion de surface emboutie formée sur la plaque de renfort et s' étendant autour du troisième trou cylindrique. Selon un mode de réalisation particulier, la première portion de surface emboutie s'étend entre le trou coopérant avec la portée cylindrique de centrage et le trou de forme oblongue.  According to an advantageous configuration, the reinforced zone, provided with three cylindrical holes, comprises a first stamped surface portion formed on the panel and extending between two of the three cylindrical holes and a second stamped surface portion formed on the reinforcing plate and extending around the third cylindrical hole. According to a particular embodiment, the first stamped surface portion extends between the hole cooperating with the centering cylindrical bearing surface and the oblong hole.
Avantageusement, les surfaces de contact sont séparées les unes des autres par une zone de passage pour un fluide de cataphorèse. Advantageously, the contact surfaces are separated from each other by a passage zone for a cataphoresis fluid.

For the sake of clarity, identical or similar elements of the various embodiments are marked with identical reference signs throughout the figures.
En relation avec les figures 1 à 6, il est décrit une structure 1 pour ouvrant de véhicule comprenant un panneau interne 2 de porte (appelé également caisson) et une plaque de renfort 3, le panneau et la plaque formant une zone renforcée . In relation with FIGS. 1 to 6, there is described a structure 1 for a vehicle opening comprising a panel internal door 2 (also called box) and a reinforcing plate 3, the panel and the plate forming a reinforced zone.
La structure 1 comporte en outre un logement 40 destiné à recevoir une serrure. Le logement 40 est formé par une découpe réalisée dans la zone renforcée 4.  The structure 1 further comprises a housing 40 for receiving a lock. The housing 40 is formed by a cut made in the reinforced zone 4.
De manière classique en soi, le panneau interne 2 et la plaque de renfort 3 sont des pièces en tôles. La plaque de renfort 3 est fixée à l'intérieur du panneau interne 2, de préférence par soudure. Avec le terme « intérieur », on désigne la face disposée en regard du panneau externe lorsque le panneau interne est assemblé avec celui-ci.  In a conventional manner, the inner panel 2 and the reinforcing plate 3 are sheet metal parts. The reinforcing plate 3 is fixed inside the inner panel 2, preferably by welding. With the term "interior" is meant the face disposed opposite the outer panel when the inner panel is assembled therewith.
La présence d'un tel renfort permet de prévoir un panneau interne 2 ayant une épaisseur moindre que celle d'un panneau interne non renforcé. Cela permet ainsi non seulement de diminuer la masse du panneau interne 2, mais également de faciliter l'emboutissage de celui-ci. La plaque de renfort 3 présente une épaisseur supérieure à celle du panneau interne 2.  The presence of such a reinforcement allows to provide an inner panel 2 having a thickness less than that of an unreinforced inner panel. This thus not only reduces the mass of the inner panel 2, but also to facilitate the stamping thereof. The reinforcing plate 3 has a thickness greater than that of the inner panel 2.
La plaque de renfort 3 est destinée à maintenir fixe sur le panneau interne 2 une plaque sur laquelle est montée la serrure (figures 4 et 5) . Cette dernière est appelée par la suite platine de serrure ou plaque de serrure 9.  The reinforcing plate 3 is intended to hold fixed on the inner panel 2 a plate on which is mounted the lock (Figures 4 and 5). The latter is called thereafter lock plate or lock plate 9.
La plaque de serrure 9 est assemblée à la zone renforcée 4 au moyen de vis de fixation 80 traversant chacune un trou associé prévu dans la zone renforcée 4. Dans le mode de réalisation décrit, l'assemblage est réalisé au moyen de trois vis de fixation 80 traversant associées à trois trous 5, 6, 7.  The lock plate 9 is assembled to the reinforced zone 4 by means of fastening screws 80 each passing through an associated hole provided in the reinforced zone 4. In the embodiment described, the assembly is made by means of three fastening screws. 80 crossing associated with three holes 5, 6, 7.
Outre de permettre la fixation d'une plaque de serrure In addition to allowing the fixing of a lock plate
9 sur la zone renforcée 4, les vis de fixation 80 ont pour avantage d'assurer un positionnement précis de la plaque de serrure 9 sur la zone renforcée 4. Plus particulièrement, les vis de fixation 80 présentent une configuration particulière pour assurer leur centrage dans le trou qu'elles traversent, et ainsi participer au positionnement correct de la plaque de serrure 9 sur la zone renforcée 4.9 on the reinforced zone 4, the fixing screws 80 have the advantage of ensuring precise positioning of the lock plate 9 on the reinforced zone 4. More particularly, the fixing screws 80 have a particular configuration to ensure their centering in the hole they cross, and thus participate in the positioning correct of the lock plate 9 on the reinforced zone 4.
Chacune des vis de fixation 80 comporte une tête 83 prolongée par une tige filetée 81. Selon l'invention, la tige 81 est pourvue d'un épaulement de centrage s' étendant radialement et délimitant avec la face inférieure de la tête 83 une portée cylindrique de centrage 82. La portée de centrage 82, formée directement sous la tête 83 de la vis de fixation 80, présente ainsi un diamètre inférieur à celui de la tête 83 mais supérieur à celui de la tige filetée 81 de la vis 80. Il est par ailleurs concentrique à la tête 83 (figure 3) . Each of the fixing screws 80 comprises a head 83 extended by a threaded rod 81. According to the invention, the rod 81 is provided with a centering shoulder extending radially and delimiting with the lower face of the head 83 a cylindrical bearing surface. 82. The centering surface 82, formed directly under the head 83 of the fixing screw 80, thus has a diameter smaller than that of the head 83 but greater than that of the threaded rod 81 of the screw 80. It is otherwise concentric to the head 83 (Figure 3).
Avantageusement, la portée de centrage 82 présente une hauteur supérieure à l'épaisseur de la zone renforcée 4. Cela permet ainsi à la plaque de serrure 9 de venir en appui contre la portée de centrage 82. La partie de la portée de centrage 82 s 'étendant au-delà du trou permet ainsi d'assurer des points de contact 30 avec la plaque de serrure 9 lorsque celle-ci est montée sur la partie renforcée 4. Un tel arrangement a également l'avantage de permettre un centrage "automatique" de la plaque de serrure 9 sur la zone renforcée 4.  Advantageously, the centering surface 82 has a height greater than the thickness of the reinforced zone 4. This thus allows the lock plate 9 to bear against the centering surface 82. The portion of the centering surface 82 s extending beyond the hole thus ensures contact points 30 with the lock plate 9 when it is mounted on the reinforced portion 4. Such an arrangement also has the advantage of allowing an "automatic" centering of the lock plate 9 on the reinforced zone 4.
Avantageusement, la tête de vis 83 comporte un moyen de prise 84 permettant la prise de la vis par un outil de serrage (non représenté) . Dans le mode de réalisation illustré, le moyen de prise 84 est formé par une rainure.  Advantageously, the screw head 83 comprises a gripping means 84 enabling the screw to be gripped by a clamping tool (not shown). In the illustrated embodiment, the engaging means 84 is formed by a groove.
Comme précédemment indiqué, la zone renforcée 4 comporte trois trous 5, 6, 7 ménagés pour être placés en vis-à-vis de trois trous de fixation ménagés dans la plaque de serrure 9 lors de l'assemblage de cette dernière avec la zone renforcée 4 et permettre ainsi le passage des vis de fixation 80.  As previously indicated, the reinforced zone 4 comprises three holes 5, 6, 7 arranged to be placed opposite three fixing holes formed in the lock plate 9 during assembly of the latter with the reinforced zone. 4 and thus allow the passage of the fixing screws 80.
Les trois trous 5, 6, 7 sont répartis autour du logement 40 recevant la serrure. Deux des trous 5, 6 sont alignés selon un axe vertical, de part et d'autre du logement 40, le troisième trou 7 étant disposé aligné avec l'un des deux trous 5, 6 selon un axe horizontal. Dans le mode de réalisation illustré sur les figures lb et 2b, le trou 5 est disposé au-dessus du logement 40 et le trou 6 au- dessous du logement. The three holes 5, 6, 7 are distributed around the housing 40 receiving the lock. Two of the holes 5, 6 are aligned along a vertical axis, on either side of the housing 40, the third hole 7 being disposed aligned with one of the two holes 5, 6 along a horizontal axis. In the embodiment illustrated in Figures lb and 2b, the hole 5 is disposed above the housing 40 and the hole 6 below the housing.
Dans la description, les termes « vertical » et « horizontal» sont définis par rapport à la position finale du panneau interne 2 sur le véhicule, ie. lorsque l'ouvrant est monté sur le véhicule.  In the description, the terms "vertical" and "horizontal" are defined with respect to the final position of the inner panel 2 on the vehicle, ie. when the opening is mounted on the vehicle.
Le premier trou 5, de forme circulaire, présente un diamètre calibré de sorte à permettre le passage de la portée de centrage 82. Par diamètre calibré, on entend un diamètre déterminé pour recevoir, avec un faible jeu, la portée de centrage 82 de la vis de fixation 80. Ainsi configuré, le premier trou 5 constitue un trou de centrage de la vis de fixation sur la zone renforcée 4. Ce premier trou 5 ainsi calibré permet, une fois la plaque de serrure 9 pré-positionnée sur la zone renforcée 4 au moyen de la languette 10 prévue à cet effet sur la plaque de renfort 3, d'assurer que la plaque de fixation 9 soit correctement positionnée sur la zone renforcée 4.  The first hole 5, circular in shape, has a calibrated diameter so as to allow the passage of the centering surface 82. By calibrated diameter means a determined diameter to receive, with a small clearance, the centering surface 82 of the fixing screw 80. Thus configured, the first hole 5 is a centering hole of the fastening screw on the reinforced zone 4. This first hole 5 and calibrated allows, once the lock plate 9 pre-positioned on the reinforced area 4 by means of the tongue 10 provided for this purpose on the reinforcing plate 3, to ensure that the fixing plate 9 is correctly positioned on the reinforced zone 4.
Le deuxième trou 6, de forme sensiblement oblongue, est agencé de façon à compenser d'éventuels écarts de positionnement ou de dimension entre les trous ménagés dans la zone renforcée 4 et les trous de fixation de la plaque de serrure 9. On parlera par la suite de trou d'ajustement. Plus particulièrement, le trou d'ajustement 6 s'étend suivant un axe s' étendant en direction du trou de centrage 5. Cette configuration présente l'avantage de permettre d'ajuster la position de la vis de fixation sur la zone renforcée et ainsi compenser d'éventuels écarts entre l'emplacement des trous de fixation de la plaque de fixation 4 et l'emplacement du trou associé ménagé sur la zone renforcée 4.  The second hole 6, of substantially oblong shape, is arranged to compensate for any differences in positioning or size between the holes formed in the reinforced zone 4 and the fixing holes of the lock plate 9. We will speak by the following adjustment hole. More particularly, the adjustment hole 6 extends along an axis extending in the direction of the centering hole 5. This configuration has the advantage of making it possible to adjust the position of the fastening screw on the reinforced zone and thus to compensate for possible differences between the location of the fixing holes of the fixing plate 4 and the location of the associated hole formed on the reinforced zone 4.
Le troisième trou 7 présente avantageusement un diamètre supérieur à celui de la portée de centrage 82 de sorte qu'il n'a comme fonction que celle de recevoir la vis de fixation associée. On parlera par la suite de trou de fixation. En d'autres termes, le troisième trou 7 est agencé pour ne pas intervenir dans le centrage de la plaque de fixation 9 lors de son positionnement sur la zone renforcée 4, sa seule fonction étant de fixer la plaque de serrure 9 sur la zone renforcée. The third hole 7 advantageously has a diameter greater than that of the centering surface 82 so that its only function is to receive the associated fixing screw. We will talk about the hole of fixation. In other words, the third hole 7 is arranged not to intervene in the centering of the fixing plate 9 during its positioning on the reinforced zone 4, its only function being to fix the lock plate 9 on the reinforced zone .
Afin d'améliorer l'interface entre la plaque de serrure 9 et la zone renforcée 4, des surfaces de contact 11, 12 entre la plaque de renfort 3 et le panneau interne 2 sont formées. Dans le mode de réalisation décrit, les surfaces de contact 11 consistent en des portions de surface de la plaque de renfort 3 et du panneau 2 embouties s' étendant autour des trous de fixation 5, 6, 7.  In order to improve the interface between the lock plate 9 and the reinforced area 4, contact surfaces 11, 12 between the reinforcing plate 3 and the inner panel 2 are formed. In the embodiment described, the contact surfaces 11 consist of surface portions of the reinforcing plate 3 and the stamped panel 2 extending around the fixing holes 5, 6, 7.
Plus précisément, la zone renforcée 4 comporte deux surfaces de contact principales 11, 12 : une première surface de contact 11 délimitée par une portion de surface emboutie 110 ménagée sur le panneau interne 2 et s' étendant entre le trou de centrage 5 et le trou d'ajustement 6 et une deuxième surface de contact 12 délimitée par une portion de surface emboutie 120 ménagée sur la plaque de renfort 3 et s' étendant autour du trou de fixation 7.  More specifically, the reinforced zone 4 comprises two main contact surfaces 11, 12: a first contact surface 11 delimited by a pressed surface portion 110 formed on the inner panel 2 and extending between the centering hole 5 and the hole 6 and a second contact surface 12 delimited by a pressed surface portion 120 formed on the reinforcing plate 3 and extending around the fixing hole 7.
Bien entendu, il peut être prévu d'autres portions de surface embouties, et donc d'autres surfaces de contact. En particulier, dans le mode de réalisation illustré sur la figure 2b, la plaque de renfort 3 comporte, outre la surface de contact s' étendant autour du trou de fixation 7, quatre surfaces de contact complémentaires disposées en bordure de la plaque de renfort 3 et représentées respectivement sous les références 13.  Of course, it may be provided other surface portions stamped, and therefore other contact surfaces. In particular, in the embodiment illustrated in FIG. 2b, the reinforcing plate 3 comprises, in addition to the contact surface extending around the fixing hole 7, four complementary contact surfaces disposed at the edge of the reinforcing plate 3. and respectively represented under the references 13.
Avantageusement, les surfaces de contact sont séparées les unes des autres par une zone de passage 21 pour un fluide de cataphorèse. Avantageusement, les surfaces de contact sont locales afin de prendre en compte les contraintes de cataphorèse.  Advantageously, the contact surfaces are separated from each other by a passage zone 21 for a cataphoresis fluid. Advantageously, the contact surfaces are local in order to take into account the cataphoresis constraints.
Les moyens de positionnement et de fixation tels que mis en œuvre selon l'invention permettent d'améliorer l'interface en terme de contact entre la plaque de serrure et la plaque de renfort 3. La surface de contact ainsi obtenue est représentée sur la figure 7 sous la référence 40. The positioning and fixing means as implemented according to the invention make it possible to improve the interface in terms of contact between the lock plate and the reinforcing plate 3. The contact surface thus obtained is shown in FIG. 7 under the reference 40.
L' invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention.  The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
