The guideway indexing system allows the support component (5) to be mounted in a predefined position. Removal of the indexing means releases the support component (5) along the axis of translation of the guideway (27) and thus allows the position of the support component (5) to be redefined.

Description

PIECE DE SUPPORT D'UNE PIECE DE CARROSSERIE SUR UN VEHICULE SUPPORT PART OF A BODY PIECE ON A VEHICLE
AVEC SYTEME D'INDEXAGE A GLISSIERE. WITH INTEXING SYSTEM WITH SLIDER.
L'invention concerne une pièce permettant d'assurer le support et le positionnement d'une pièce de carrosserie juxtaposée à un ouvrant. Par exemple, l'invention concerne une pièce de support de pare-choc de véhicule automobile destinée à être fixée à la caisse dudit véhicule et à être au moins partiellement couvert par une peau de pare-choc juxtaposée à un hayon. L'invention concerne également un élément de structure de caisse de véhicule automobile destiné à recevoir une telle pièce de support. Enfin l'invention concerne un véhicule comprenant au moins une telle pièce de support. Le support de pare-choc et la peau de pare-choc doivent être placés de façon précise par rapport à la caisse d'un véhicule automobile. Leur centrage permet de respecter les exigences de jeux d'affleurement avec un ouvrant pouvant prendre une position ouverte et une position fermée sur le véhicule, tel qu'un hayon. Il est connu de donner à un absorbeur de chocs arrière une fonction de support et de positionnement de la plage supérieure d'une peau de pare-choc arrière juxtaposée au hayon. Il existe à l'heure actuelle plusieurs solutions permettant d'assurer un bon positionnement des différentes pièces entre elles. The invention relates to a part for providing support and positioning of a bodywork part juxtaposed to an opening. For example, the invention relates to a motor vehicle bumper support piece intended to be fixed to the body of said vehicle and to be at least partially covered by a bumper skin juxtaposed to a tailgate. The invention also relates to a motor vehicle body structure element intended to receive such a support piece. Finally, the invention relates to a vehicle comprising at least one such support piece. The bumper support and the bumper skin must be precisely positioned in relation to the body of a motor vehicle. Their centering makes it possible to comply with the flush clearance requirements with an opening that can take an open position and a closed position on the vehicle, such as a tailgate. It is known to give a rear impact absorber a support function and positioning of the upper range of a rear bumper skin juxtaposed to the tailgate. There are currently several solutions to ensure proper positioning of the different parts together.
Une première solution, dite « gabaritée », permet de définir le positionnement de l'absorbeur de choc, et en conséquent de la peau de pare-choc qui y est fixée, par rapport au gabarit du hayon lorsqu'il est placé en position fermée. Pour ce faire, on monte d'abord le hayon sur le véhicule. On le ferme et on rapporte une cale en élastomère le long de son bord inférieur. On rapporte ensuite l'absorbeur de chocs en dessous de cette cale en le plaquant contre elle. La plaque en élastomère va définir un jeu entre l'absorbeur de chocs et le bord inférieur du hayon. On fixe ensuite définitivement l'absorbeur sur le véhicule, ou plus précisément sur l'élément arrière de structure de caisse. Une fois l'absorbeur fixé, on démonte la cale en élastomère et l'on rapporte la peau de pare-choc sur l'absorbeur. A first solution, known as "gabarite", makes it possible to define the positioning of the shock absorber, and consequently of the bumper skin that is attached thereto, relative to the template of the tailgate when it is placed in the closed position. . To do this, first assemble the tailgate on the vehicle. It is closed and reported an elastomer wedge along its lower edge. The shock absorber is then reported below this wedge by pressing against it. The elastomer plate will define a clearance between the shock absorber and the lower edge of the tailgate. The absorber is then permanently fixed on the vehicle, or more precisely on the element rear body structure. Once the absorber is attached, the elastomer wedge is removed and the bumper skin is attached to the absorber.
Un exemple de pièce de support utilisée pour assurer un positionnement selon une solution « gabaritée », est décrit dans le document FR2912987. La pièce de support, par exemple un absorbeur de choc, comprend avantageusement un système de pattes ressort formant des moyens élastiques. Lorsque le hayon est ouvert, l'absorbeur de choc est placé dans une première position peu précise. La fermeture du hayon va lui imposer un déplacement vers une seconde position par déformation de ses moyens élastiques. C'est dans cette seconde position, ou position définitive, que l'absorbeur de chocs est fixé définitivement sur l'élément arrière de structure de caisse, et donc que la pièce de carrosserie qu'elle supporte est centrée sur le véhicule. Une autre solution, dite « indexée », consiste à utiliser un moyen d'indexage pour définir précisément la position que doit prendre l'absorbeur de chocs sur l'élément arrière de structure de caisse. L'absorbeur de chocs est donc mis en position par clippage sur la caisse du véhicule, et y est fixé définitivement sans réajustement de sa position. La peau de pare-choc et le hayon sont dimensionnés pour répondre aux exigences de jeu en fonction de cette position prédéfinie de l'absorbeur de chocs. An example of a support piece used to ensure positioning according to a "template" solution is described in the document FR2912987. The support piece, for example a shock absorber, advantageously comprises a system of spring tabs forming elastic means. When the tailgate is open, the shock absorber is placed in an unspecified first position. Closing the tailgate will impose a displacement to a second position by deformation of its elastic means. It is in this second position, or final position, that the shock absorber is permanently fixed on the rear body structure element, and therefore the body part that it supports is centered on the vehicle. Another solution, called "indexed", is to use an indexing means to precisely define the position that must take the shock absorber on the rear body structure element. The shock absorber is placed in position by clipping on the vehicle body, and is fixed permanently without readjustment of its position. The bumper skin and tailgate are sized to meet game requirements based on this predefined position of the shock absorber.
Les deux solutions connues pour le positionnement d'une pièce de carrosserie juxtaposée à un ouvrant sont donc alternatives. Or, lorsqu'on réalise les premiers prototypes d'un véhicule, il faut choisir par avance quel va être le type de solution de positionnement que l'on va utiliser. Les solutions de type « indexées » sont plus économiques que les solutions de type « gabaritées » et auront donc tendance à être préférées dans la mesure du possible. Lors des essais réalisés dans le cadre de la conception d'un véhicule, il est parfois nécessaire de basculer d'une solution à l'autre. Or, s'il est actuellement faisable de partir d'une solution de type « gabaritée » pour revenir ensuite à une solution de type « indexée », l'inverse n'est pas possible. En effet, l'emploi d'une solution « gabaritée » implique de prévoir des moyens, sur l'absorbeur de chocs et sur l'élément de structure de caisse, qui vont coopérer pour guider l'absorbeur de chocs jusqu'à sa position définitive et des moyens de maintien en position jusqu'à sa fixation définitive. The two known solutions for the positioning of a bodywork part juxtaposed with an opening are therefore alternatives. However, when making the first prototypes of a vehicle, you must choose in advance what will be the type of positioning solution that we will use. "Indexed" type solutions are more economical than "gabarity" solutions and will therefore tend to be preferred wherever possible. During tests carried out as part of the design of a vehicle, it is sometimes necessary to switch from one solution to another. However, if it is currently feasible to start from a "template" type solution and then return to an "indexed" type solution, the opposite is not the case. Not possible. Indeed, the use of a "template" solution involves providing means on the shock absorber and on the body structure element, which will cooperate to guide the shock absorber to its position. definitive and means of holding in position until its final fixation.
L'invention a pour objectif de répondre aux inconvénients présentés par l'art antérieur en proposant une nouvelle pièce de positionnement permettant de passer au besoin pour son positionnement sur un élément de structure de caisse d'une solution de type « indexée » à une solution de type « gabaritée ». The object of the invention is to meet the drawbacks presented by the prior art by proposing a new positioning piece that makes it possible to switch to a situation where it is positioned on a body structure element of an "indexed" solution to a solution. of type "gabaritée".
A cet effet, l'invention a pour objet une pièce de support et de positionnement d'une pièce de carrosserie destinée à être juxtaposée avec un ouvrant remarquable en ce qu'elle comprend au moins un système d'indexage à glissière comprenant un patin et une paire de moyens d'indexage, le ou les systèmes d'indexage à glissière étant destinés à coopérer avec une ou des glissières d'un élément de structure de caisse pour positionner et retenir ladite pièce de support contre l'élément de structure de caisse en vue de sa fixation sur ledit élément de structure de caisse. For this purpose, the subject of the invention is a piece for supporting and positioning a bodywork part intended to be juxtaposed with a remarkable opening in that it comprises at least one sliding indexing system comprising a skid and a pair of indexing means, the one or more sliding indexing systems being intended to cooperate with one or more rails of a body structure element for positioning and holding said support piece against the body structure element for attachment to said body structure member.

L'invention a également pour objet un véhicule comprenant une pièce de support et de positionnement d'une pièce de carrosserie destinée à être juxtaposée avec un ouvrant telle que définie plus haut, la pièce de carrosserie et l'ouvrant formant une jonction lorsqu'ils sont juxtaposés, la pièce de support comprenant un système d'indexage à glissière, et un élément de structure de caisse présentant au moins une glissière destinée à venir coopérer avec au moins un système d'indexage à glissière de la pièce de support. Préférentiellement, la glissière est disposée selon une direction perpendiculaire à la jonction entre la pièce de carrosserie et l'ouvrant. The invention also relates to a vehicle comprising a support and positioning part of a bodywork part intended to be juxtaposed with an opening as defined above, the bodywork part and the opening forming a junction when are juxtaposed, the support member comprising a sliding indexing system, and a body structure member having at least one slide intended to cooperate with at least one sliding indexing system of the support piece. Preferably, the slideway is arranged in a direction perpendicular to the junction between the bodywork part and the opening.
De préférence, le système d'indexage à glissière comprend un patin présente une tête, et la glissière se présente sous forme d'un trou oblong avec un dégagement suffisant pour le passage de la tête du patin. De préférence encore, la longueur de la glissière est équivalente à la distance présentée par les éléments de la paire de moyens d'indexage de sorte à ce que les dits éléments de la paire de moyens d'indexage puissent s'insérer dans la glissière et venir se placer en butée contre les extrémités de la glissière. Preferably, the sliding indexing system comprises a shoe has a head, and the slide is in the form of an oblong hole with sufficient clearance for the passage of the head of the pad. More preferably, the length of the slide is equivalent to the distance presented by the elements of the pair of indexing means so that said elements of the pair of indexing means can be inserted into the slide and come to abut against the ends of the slide.
L'invention a enfin pour objet un procédé de positionnement d'une pièce de support sur un élément de structure de caisse au cours duquel : The invention finally relates to a method of positioning a support piece on a body structure element in which:
- on engage un pion d'indexage et une tête de patin portés par la pièce de support dans une glissière formée d'un trou oblong dans l'élément de structure de caisse,  an indexing pin and a skid head carried by the support piece are engaged in a slide formed of an oblong hole in the body structure element,
- on pousse la pièce de support selon la direction de translation autorisée par la glissière jusqu'à ce que le pion d'indexage vienne se poser en butée contre l'une des extrémités de la glissière limitant le déplacement de la pièce de support dans la glissière selon un premier sens,  the support piece is pushed along the direction of translation authorized by the slideway until the indexing pin comes into abutment against one of the ends of the slideway limiting the displacement of the support piece in the slide according to a first sense,
- un clip porté par la pièce de support se déploie automatiquement dans la glissière au niveau de son extrémité opposée limitant le déplacement de la pièce de support dans la glissière selon le deuxième sens de translation, opposé au premier sens, a clip carried by the support piece is automatically deployed in the slideway at its opposite end limiting the movement of the support piece in the slide in the second direction of translation, opposite to the first direction,
- on fixe définitivement la pièce de support ainsi immobilisée sur l'élément de structure de caisse. the support piece thus immobilized is fixed permanently on the body structure element.
Comme on l'aura compris à la lecture de la définition qui vient d'en être donnée, l'invention consiste à proposer une pièce de support pour un montage par indexage, correspondant à une solution de type « indexée », impliquant un positionnement prédéfini de la pièce de support aussi bien selon les directions longitudinale (X), transversale (Y) que verticale (Z) par rapport à l'élément de structure de caisse. Selon l'invention, le montage de la pièce de support sur ledit élément de structure de caisse implique un mouvement de translation dans un guide, par exemple une glissière, porté par l'élément de structure de caisse selon une direction perpendiculaire à la jonction entre la pièce de carrosserie et l'ouvrant. Dans le cas d'une pièce de support destinée à supporter une peau de pare-choc et à la positionner par rapport au hayon d'un véhicule automobile, cette direction est verticale. L'emploi d'un guide sur l'élément de structure de caisse, coopérant avec un patin porté par la pièce de support, permet à la pièce de support d'être positionnée de manière prédéfinie selon les directions longitudinale (X) et transversale (Y). Le positionnement prédéfini selon la direction verticale (Z) est assuré par des moyens d'indexage associés au patin et coopérant avec le guide, de sorte à immobiliser le patin dans le guide. As will be understood from reading the definition that has just been given, the invention consists in proposing a support piece for an indexing assembly, corresponding to an "indexed" type solution, implying a predefined positioning of the support piece both in the longitudinal (X), transverse (Y) and vertical (Z) directions with respect to the body structure element. According to the invention, the mounting of the support piece on said body structure element involves a translational movement in a guide, for example a slide, carried by the body structure element in a direction perpendicular to the junction between the body part and the opening. In the case of a support piece intended to support a bumper skin and to position it relative to the tailgate of a motor vehicle, this direction is vertical. The use of a guide on the body structure element, cooperating with a pad carried by the support piece, allows the support piece to be positioned in a predefined manner along the longitudinal (X) and transverse ( Y). The predefined positioning in the vertical direction (Z) is provided by indexing means associated with the pad and cooperating with the guide, so as to immobilize the pad in the guide.
L'invention consiste donc à proposer une solution « indexée » dont les moyens d'indexage ne définissent le positionnement de la pièce de support sur l'élément de structure de caisse que selon une direction perpendiculaire à la jonction entre la pièce de carrosserie et l'ouvrant. Le centrage selon les autres directions est assuré par la coopération d'au moins un patin de la pièce support avec au moins un guide ou une glissière dédiée de l'élément de structure de caisse. Ceci permet, en coupant lesdits moyens d'indexage, de rétablir la liberté de mouvement de la pièce de support par rapport à l'élément de structure de caisse selon cette direction. Lorsque les moyens d'indexage sont retirés, la pièce de support, montée sur l'élément de structure de caisse, est mobile en translation selon une direction perpendiculaire à la jonction entre la pièce de carrosserie et l'ouvrant tout en présentant un positionnement prédéfini par rapport aux deux autres directions perpendiculaires à sa direction de translation. La pièce de support présente donc des moyens suffisants pour être mise en position selon un procédé de montage compatible avec une solution de type « gabaritée ». L'invention consiste à pourvoir une pièce de support d'un double moyen de positionnement, à savoir un patin destiné à coopérer avec un guide ou une glissière de l'élément de structure de caisse, et une paire de moyens d'indexage pour limiter le mouvement de la pièce de support selon les deux sens de la direction de translation autorisée par le guide ou la glissière. L'invention permet de fournir à l'homme du métier une pièce de support pouvant être mise en position sur un élément de structure de caisse aussi bien selon une solution « indexée » que « gabaritée » et lui permettant de choisir la plus adaptée selon les circonstances. L'invention est remarquable en ce qu'elle permet de basculer d'une solution de type « indexée » à une solution de type « gabaritée ». The invention therefore consists in proposing an "indexed" solution whose indexing means define the positioning of the support piece on the body structure element only in a direction perpendicular to the junction between the bodywork piece and the body. 'opening. The centering in the other directions is provided by the cooperation of at least one pad of the support piece with at least one guide or a dedicated slide of the body structure element. This allows, by cutting said indexing means, to restore the freedom of movement of the support part relative to the body structure element in this direction. When the indexing means are removed, the support piece, mounted on the body structure element, is movable in translation in a direction perpendicular to the junction between the bodywork part and the opening while having a predefined positioning relative to the other two directions perpendicular to its direction of translation. The support piece thus has sufficient means to be placed in position according to a mounting method compatible with a "gabarite" type solution. The invention consists in providing a support piece with a double positioning means, namely a pad intended to cooperate with a guide or a slide of the body structure element, and a pair of indexing means for limiting the movement of the support piece in both directions of the translation direction allowed by the guide or slide. The invention makes it possible to provide the person skilled in the art with a support piece that can be placed in position on a body structure element as well according to an "indexed" solution as "gabaritée" and that enables it to choose the most adapted according to the circumstances. The invention is remarkable in that it makes it possible to switch from an "indexed" type solution to a "gabarite" type solution.
L'invention sera bien comprise et d'autres aspects et avantages apparaîtront clairement au vu de la description qui suit donnée à titre d'exemple en référence aux planches de dessins annexées sur lesquelles : The invention will be well understood and other aspects and advantages will become apparent from the following description given by way of example with reference to the accompanying drawings in which:
- La figure 1 est une représentation schématique en perspective éclatée d'une partie des éléments constitutifs de la caisse arrière d'un véhicule automobile. - Figure 1 is a schematic perspective exploded view of part of the constituent elements of the rear body of a motor vehicle.
- La figure 2 est une vue schématique en perspective de l'avant d'une partie d'une pièce de support selon l'invention. - Figure 2 is a schematic perspective view of the front of a portion of a support part according to the invention.
- La figure 3 est une vue de l'avant d'un élément de structure de caisse présentant une glissière dans laquelle s'est inséré le système d'indexage à glissière selon l'invention. - La figure 4 est une vue schématique en perspective de l'avant d'une partie d'une pièce de support selon l'invention présentant en outre des pattes ressort. On se référera en premier lieu à la figure 1 présentant la partie arrière inférieure d'un véhicule comprenant un ouvrant arrière (1 ) ou hayon, un élément (3) arrière de structure de caisse d'un véhicule, une pièce de support (5) de pare-choc destinée à être positionnée puis fixée sur l'élément (3) de structure de caisse, et une peau de pare-choc (7) destinée à être montée sur la pièce de support (5) de pare-choc. La peau (7) de pare-choc est destinée à être juxtaposée au hayon (1 ) arrière du véhicule. Le hayon (1 ) arrière peut prendre une position ouverte ou une position fermée. Pour des raisons de clarté, les feux arrière et leurs supports de feux n'ont pas été représentés. Dans notre exemple, nous décrirons le positionnement de la pièce de support (5) de pare-choc sur l'élément (3) arrière de structure de caisse du véhicule. Dans notre exemple de réalisation, la pièce de support (5) est un absorbeur de chocs. Néanmoins la localisation de la pièce de support (5) à l'arrière du véhicule ne saurait être limitative de l'invention. Par exemple, la pièce de support peut permettre de positionner une pièce de carrosserie avant, juxtaposée à un capot avant. A cet effet, la pièce de support peut être constituée d'une grille de calandre, d'un rebord intérieur de peau de pare-choc avant, ou d'une face avant technique supportant un radiateur. Il est également envisageable d'utiliser la pièce de support selon l'invention pour assurer le positionnement d'une pièce de carrosserie latérale avec une portière. - Figure 3 is a front view of a body structure member having a slide in which is inserted the sliding indexing system according to the invention. - Figure 4 is a schematic perspective view of the front of a portion of a support member according to the invention further having spring tabs. Referring firstly to Figure 1 showing the lower rear part of a vehicle comprising a rear opening (1) or tailgate, a rear element (3) of a vehicle body structure, a support part (5). ) bumper to be positioned and attached to the body structure element (3), and a bumper skin (7) to be mounted on the bumper support piece (5). The skin (7) bumper is intended to be juxtaposed to the rear tailgate (1) of the vehicle. The tailgate (1) rear can take an open position or a closed position. For the sake of clarity, the taillights and their light holders were not shown. In our example, we will describe the positioning of the bumper support part (5) on the rear body structure element (3) of the vehicle. In our exemplary embodiment, the support piece (5) is a shock absorber. Nevertheless, the location of the support piece (5) at the rear of the vehicle can not be limited to the invention. For example, the support piece can be used to position a front bodywork part, juxtaposed to a front cover. For this purpose, the support piece may consist of a grille, an inner rim of bumper skin front, or a technical front supporting a radiator. It is also conceivable to use the support piece according to the invention to ensure the positioning of a side bodywork part with a door.
En se reportant aux figures 2 et 3, on voit que la pièce de support (5) présente des moyens (19, 21 , 23) destinés à coopérer avec des moyens complémentaires (27, représentés sur la figure 3) situés sur l'élément (3) arrière de structure de caisse pour sa mise en position sur ledit élément (3) arrière de structure de caisse et son maintien en position le temps de sa fixation définitive. A cet effet, la pièce de support (5) présente au moins un système d'indexage à glissière comprenant un patin (21 ) associé à une paire de moyens d'indexage (19, 23). Le patin (21 ) est destiné à être inséré dans une glissière (27) de l'élément (3) de structure de caisse. Avantageusement, la glissière (27) se présente sous forme d'un trou oblong présentant un dégagement au niveau d'une de ses extrémités pour le passage du patin (21 ). Eventuellement, le patin (21 ) est monté sur un support (17) disposé en travers d'un ajour (13) offrant une visibilité au monteur pour son insertion dans le dégagement de la glissière (27). La glissière (27) est configurée pour autoriser une translation de la pièce de support (5) par rapport à l'élément (3) de structure de caisse selon une direction perpendiculaire à la jonction entre l'ouvrant, à savoir le hayon, et la pièce de carrosserie, à savoir la peau de pare choc. La direction de translation autorisée par la glissière (27) est dans notre exemple une direction verticale selon un axe Z. Avantageusement, l'extrémité de la glissière (21 ) présentant le dégagement est disposée supérieure à l'autre extrémité selon la direction verticale. De la sorte, lors du montage de la pièce de support (5) sur l'élément (3) de structure de caisse, le monteur, après avoir inséré le patin (21 ) dans le dégagement de la glissière, effectuera un mouvement de poussée vers le bas de la pièce de support (5) par rapport à l'élément (3) de structure de caisse, pour la mettre en position. Referring to Figures 2 and 3, we see that the support member (5) has means (19, 21, 23) for cooperating with complementary means (27, shown in Figure 3) located on the element (3) rear body structure for its positioning on said rear body structure element (3) and its holding in position the time of its final fixation. For this purpose, the support (5) has at least one sliding indexing system comprising a shoe (21) associated with a pair of indexing means (19, 23). The shoe (21) is intended to be inserted into a slide (27) of the body structure element (3). Advantageously, the slide (27) is in the form of an oblong hole having a clearance at one of its ends for the passage of the pad (21). Optionally, the shoe (21) is mounted on a support (17) disposed across an opening (13) providing visibility to the fitter for insertion into the clearance of the slide (27). The slide (27) is configured to allow a translation of the support piece (5) relative to the body structure element (3) in a direction perpendicular to the junction between the opening, namely the tailgate, and the body part, namely the bumper skin. The direction of translation allowed by the slide (27) is in our example a vertical direction along an axis Z. Advantageously, the end of the slide (21) having the clearance is disposed greater than the other end in the vertical direction. In this way, when mounting the support piece (5) on the body structure element (3), the fitter, after inserting the shoe (21) in the clearance of the slide, will make a pushing movement down the support piece (5) relative to the body structure element (3), to put it in position.
On aura compris que l'utilisation d'un système d'indexage à glissière permet de prédéfinir le positionnement de la pièce de support (5) sur l'élément (3) de structure de caisse selon la direction transversale du véhicule, à savoir la direction d'axe Y, par l'insertion du pied du patin (21 ) dans la glissière (27). A cet effet, la largeur de la glissière (27) est, en dehors de son dégagement, équivalente à la largeur du pied du patin (21 ). It will be understood that the use of a sliding indexing system predefines the positioning of the support piece (5) on the body structure element (3) in the transverse direction of the vehicle, namely the Y axis direction, by inserting the foot of the shoe (21) in the slide (27). For this purpose, the width of the slide (27) is, apart from its clearance, equivalent to the width of the foot of the pad (21).
Elle permet également de prédéfinir le positionnement de la pièce de support (5) sur l'élément (3) de structure de caisse selon la direction longitudinale du véhicule, à savoir la direction d'axe X. A cet effet, lorsque le patin (21 ) est inséré dans la glissière, la tête du patin (21 ) va coopérer avec l'élément (3) de structure de caisse (ou la glissière si celle-ci est rapportée) pour retenir la pièce de support (5) contre ledit élément (3) de structure de caisse. Avantageusement, la pièce de support (5) présente, sur sa face (9) destinée à être placée en regard de l'élément (3) de structure de caisse, des éléments saillants ou écarteurs (15), par exemple des nervures (15). Ceci permet de définir un écartement minimal entre la pièce de support (5) et l'élément (3) de structure de caisse lorsque la pièce de support (5) est positionnée contre l'élément (3) de structure de caisse. L'emploi d'écarteurs (15) est particulièrement avantageux pour minimiser les zones de frottement entre la pièce de support (5) et l'élément (3) de structure de caisse lors des mouvements de translation de l'un par rapport à l'autre durant leur mise en position. It also makes it possible to predefine the positioning of the support piece (5) on the body structure element (3) in the longitudinal direction of the vehicle, namely the X axis direction. For this purpose, when the shoe ( 21) is inserted in the slide, the head of the shoe (21) will cooperate with the body structure element (3) (or the slide if it is reported) to retain the support piece (5) against said element (3) of structure checkout. Advantageously, the support piece (5) has, on its face (9) intended to be placed facing the body structure element (3), projecting elements or spacers (15), for example ribs (15). ). This makes it possible to define a minimum distance between the support piece (5) and the body structure element (3) when the support piece (5) is positioned against the body structure element (3). The use of spacers (15) is particularly advantageous for minimizing the areas of friction between the support part (5) and the body structure element (3) during the translation movements of one relative to the other. other during their setting in position.
L'ensemble patin-glissière (21 ,27) fait donc office de butée selon les directions X et Y, perpendiculaires à la direction d'enfoncement de la pièce de support (5) dans la glissière (27). Sur la figure 3, les flèches illustrent la direction d'enfoncement du patin (21 ) dans la glissière (27) tel que vu depuis la face avant (25) de l'élément (3) de structure de caisse. Le positionnement de la pièce de support (5) selon les axes X et Y est donc acquis par l'emploi un système de glissière (21 , 27), et ce que la pièce de support (5) soit employée pour un montage selon une solution « indexée » ou selon une solution « gabaritée ». The runner-slide assembly (21, 27) therefore serves as a stop in the X and Y directions, perpendicular to the direction of insertion of the support piece (5) into the slide (27). In Figure 3, the arrows illustrate the direction of depression of the shoe (21) in the slide (27) as seen from the front face (25) of the body structure element (3). The positioning of the support piece (5) along the X and Y axes is therefore acquired by the use of a slide system (21, 27), and that the support piece (5) is used for mounting according to a solution "indexed" or according to a solution "gabaritée".
Lorsque le montage se fait selon une solution « indexée », le positionnement de la pièce de support (5) selon l'axe vertical se fait grâce à une paire de moyens d'indexage (19, 23) associés au patin (21 ). De préférence, au moins un de ces moyens d'indexage est un élément d'emboîtage élastique, par exemple un clip (23). De préférence, l'un des moyens d'indexage est un pion (19) d'indexage. Le pion (19) est dimensionné pour pouvoir s'insérer dans la glissière (27). Le pion (19) est destiné à limiter le déplacement de la pièce de support (5) vers le bas le long de la glissière (27) en se plaçant en butée contre l'extrémité inférieure de la glissière (27). Le pion (19) et le clip (23) sont écartés l'un l'autre d'une distance équivalente à la distance séparant les extrémités de la glissière (27). Si bien que lorsque le pion (19) vient se positionner en butée contre l'extrémité inférieure de la glissière, le clip (23) se déploie et s'insère dans la glissière au niveau de son extrémité supérieure. Le clip (23) est destiné à limiter le déplacement vers le haut en se plaçant en butée contre l'extrémité supérieure de la glissière. La paire de moyen d'indexage, s'insérant dans la glissière et venant en butée contre les deux extrémités de la glissière, va donc empêcher tout mouvement de la pièce de support (5) selon l'axe Z et donc la positionner selon une position prédéfinie selon l'axe Z. When the assembly is done according to an "indexed" solution, the positioning of the support part (5) along the vertical axis is done through a pair of indexing means (19, 23) associated with the pad (21). Preferably, at least one of these indexing means is an elastic casing element, for example a clip (23). Preferably, one of the indexing means is an indexing pin (19). The pin (19) is sized to fit into the slide (27). The pin (19) is intended to limit the movement of the support piece (5) downwards along the slide (27) by placing itself in abutment against the lower end of the slide (27). The pin (19) and the clip (23) are separated from each other by a distance equivalent to the distance separating the ends of the slide (27). So that when the pawn (19) is positioned in abutment against the lower end of the slide, the clip (23) unfolds and fits into the slide at its upper end. The clip (23) is intended to limit the movement upwards by placing itself in abutment against the upper end of the slide. The pair of indexing means, inserting into the slide and abutting against both ends of the slide, will therefore prevent any movement of the support piece (5) along the Z axis and thus position it according to a predefined position along the Z axis.
Le système d'indexage à glissière selon l'invention est particulièrement avantageux en ce qu'il permet d'assurer un positionnement de la pièce selon toutes les directions X, Y et Z, donc un positionnement isostatique, et de le maintenir ainsi jusqu'à la fixation définitive. A cet effet, la paroi avant (9) de la pièce (5) de support présente en outre des moyens (1 1 ) de fixation définitive à l'élément (3) de structure de caisse. Les moyens (1 1 ) de fixation définitive sont par exemple constitués par un trou pour le passage d'une vis de fixation. The sliding indexing system according to the invention is particularly advantageous in that it makes it possible to ensure positioning of the part in all the X, Y and Z directions, and thus isostatic positioning, and thus to maintain it up to to the final fixation. For this purpose, the front wall (9) of the support part (5) further has means (1 1) for permanently fixing the body structure element (3). The means (1 1) for permanent attachment are for example constituted by a hole for the passage of a fixing screw.
Lorsqu'on souhaite que le montage se fasse selon une solution « gabaritée », on coupe la paire de moyens d'indexage (19, 23). La suppression du clip (23) et/ou du pion (19) se fait par tous moyens. Néanmoins, le clip (23) et/ou le pion (19) sont préférentiellement configurés pour être sécables. La suppression des moyens d'indexage selon la direction perpendiculaire à la jonction entre l'ouvrant et la pièce de carrosserie - à savoir la direction verticale dans notre exemple - permet de ne conserver que le système à glissière compatible avec une solution « gabaritée ». Le positionnement en X et Y est assuré par la mise en place du patin (21 ) dans la glissière (27). Un monteur va pousser la pièce de support (5) contre le hayon en position fermée (ou contre les cales en élastomère disposées sous le hayon) pour assurer le positionnement en Z. When it is desired that the mounting is done according to a "template" solution, the pair of indexing means (19, 23) is cut off. The removal of the clip (23) and / or the pin (19) is done by any means. Nevertheless, the clip (23) and / or the pin (19) are preferentially configured to be scored. The removal of the indexing means in the direction perpendicular to the junction between the opening and the bodywork part - namely the vertical direction in our example - makes it possible to keep only the sliding system compatible with a solution "gabaritée". The positioning in X and Y is ensured by the implementation of the pad (21) in the slide (27). An assembler will push the support piece (5) against the tailgate in the closed position (or against the elastomer wedges located under the tailgate) to ensure Z positioning.
Selon une variante de l'invention représentée à la figure 4, la pièce de support (5) comprend en outre sur sa face avant (29) au moins un moyen élastique, de préférence une patte ressort (33) placée dans une fenêtre (31 ). De préférence, elle comprend deux à cinq pattes ressort. La direction d'enfoncement exercé par le hayon sur la pièce de support (5) est parallèle à la direction de déformation des pattes ressort, soit dans notre exemple sensiblement verticale par rapport au véhicule. L'élasticité des pattes ressort va permettre de pousser la pièce de support (5) vers le haut, contre le hayon, en s'appuyant sur l'élément (3) de structure de caisse. Le fonctionnement de telles pattes ressort est connu de l'homme du métier et ne sera pas détaillé plus avant. Ces pattes sont inutiles tant que l'on emploie les moyens d'indexage mais permettent de pousser la pièce vers le haut si lesdits moyens d'indexage ont été retirés. According to a variant of the invention shown in FIG. 4, the support piece (5) further comprises on its front face (29) at least one resilient means, preferably a spring tab (33) placed in a window (31). ). Preferably she includes two to five spring legs. The driving direction exerted by the tailgate on the support piece (5) is parallel to the deformation direction of the spring tabs, in our example substantially vertical with respect to the vehicle. The elasticity of the spring tabs will allow to push the support piece (5) upwards against the tailgate, based on the body structure element (3). The operation of such spring tabs is known to those skilled in the art and will not be detailed further. These tabs are useless as long as the indexing means are used but allow to push the piece upwards if said indexing means have been removed.
L'invention ne se limite pas aux modes de réalisation décrits ci-avant, seulement à titre d'exemple mais englobe toutes les variantes que pourra envisager l'homme du métier dans le cadre de la définition qui en a été donnée. En particulier, la pièce de support peut être venue de matière avec la pièce de carrosserie. The invention is not limited to the embodiments described above, only by way of example but encompasses all the variants that may be envisaged by those skilled in the art within the framework of the definition that has been given. In particular, the support piece can be integral with the bodywork part.
