Description

DISPOSITIF DE RACCORDEMENT ETANCHE  SEALED CONNECTION DEVICE
D'UN TUYAU DE DISTRIBUTION DE LIQUIDE LAVE-VITRE. L'invention concerne le dispositif de distribution du liquide lave-vitre pour un véhicule de préférence un véhicule automobile. Plus précisément, l'invention concerne un dispositif de raccordement et de fixation d'un tuyau de liquide lave-vitre pouvant être utilisé au niveau du joint d'étanchéité d'un capot de véhicule automobile.  A WINDOW FLUID LIQUID DISPENSING PIPE. The invention relates to the device for dispensing windshield washer fluid for a vehicle, preferably a motor vehicle. More specifically, the invention relates to a device for connecting and fixing a windshield washer fluid pipe that can be used at the seal of a motor vehicle hood.
Afin d'éviter l'endommagement des pièces constitutives du moteur de véhicule par l'eau de pluie ou par le liquide lave-vitre, il est connu de disposer entre l'arrière du capot et le compartiment moteur un joint d'étanchéité. Celui-ci est généralement constitué par un tuyau de section circulaire qui vient s'écraser contre le capot ou sa doublure. Un problème d'étanchéité au niveau de ce joint a été relevé lorsque les gicleurs de liquide lave-vitre ne sont pas placés sur le capot mais sont dissimulés et placés sous le capot. En effet, en se référant à la figure 1 montrant un capot (1 ) muni d'une doublure (3) avec des gicleurs (5) disposés sur la doublure (3), on peut constater que pour pouvoir alimenter les gicleurs (5) en liquide lave-vitre, le tuyau de distribution (7) du liquide doit franchir le joint arrière d'étanchéité (9). Des fuites ont été constatées au niveau du passage du tuyau de distribution (7) de liquide lave-vitre. De ce fait, de l'eau ou du liquide lave-vitre peuvent goutter à l'intérieur du bloc moteur, sur l'alternateur par exemple, ce qui risque de l'endommager.  In order to avoid damage to the constituent parts of the vehicle engine by rain water or windscreen washer fluid, it is known to arrange a seal between the rear of the hood and the engine compartment. This is usually constituted by a circular section of pipe that collapses against the hood or its lining. A sealing problem at this seal has been noted when the washer fluid nozzles are not placed on the hood but are hidden and placed under the hood. Indeed, with reference to Figure 1 showing a cover (1) provided with a liner (3) with nozzles (5) disposed on the liner (3), it can be seen that to power the nozzles (5) in window washing liquid, the distribution pipe (7) of the liquid must pass through the rear seal (9). Leaks were observed at the passage of the dispensing pipe (7) of windshield washer fluid. As a result, water or windshield washer fluid may drip inside the engine block, for example on the alternator, which may damage it.
Le problème de la distribution de liquide lave-vitre sous le capot notamment par le passage du joint d'étanchéité a déjà été étudié dans l'art antérieur.  The problem of the distribution of windshield washer fluid under the hood, in particular by the passage of the gasket, has already been studied in the prior art.
Ainsi, le document FR2668568 propose de contourner le joint. En effet ce document décrit un joint d'étanchéité pour véhicule automobile comportant un conduit intégré qui s'étend parallèlement à la direction longitudinale du joint. Ce conduit est obtenu par moulage en même temps que le joint. Il peut être utilisé pour transporter le liquide lave- vitre. De ce fait, il n'est plus nécessaire que le tuyau de distribution franchise le joint d'étanchéité puisqu'il y est intégré. Néanmoins cette solution, implique l'utilisation de joints spéciaux et des modifications structurelles du circuit de distribution de liquide lav- vitre. Le document JP2008025797 divulgue un dispositif pour prévenir l'écrasement le tuyau de distribution du liquide lave-vitre par le joint d'étanchéité du capot lorsque le tuyau est coincé entre le capot et le joint. Pour ce faire, il est proposé de fixer sur le capot, au niveau du joint, une pièce de raccordement présentant une section transversale de forme générale sensiblement semi-elliptique. Cette pièce de raccordement est réalisée en matériau élastique et se déforme sous l'effet de la pression du joint afin d'éviter de générer des espaces libres au niveau de ses extrémités latérales entre le capot et le joint. Les ouvertures ainsi créées seraient en effet préjudiciables à l'étanchéité de l'ensemble. Elle présente une surface plane pourvue de moyens de fixations qui est destinée à être collée ou accrochée sur le capot et une surface convexe destinée à coopérer avec le joint pour assurer l'étanchéité lors de la fermeture du capot. Elle comprend en outre un conduit interne s'étendant de part et d'autre de la pièce sous forme d'embouts. Le tuyau de distribution de liquide lave vitre est coupé en deux. Chaque extrémité du tuyau est raccordée à un embout de la pièce de raccordement. Le liquide lave-vitre traverse ainsi la pièce de raccordement. La pièce de raccordement présente une résistance à l'écrasement par le joint supérieure à celle du tuyau de distribution et sa forme est adaptée pour coopérer avec lui en vue d'assurer l'étanchéité. Si cette solution semble efficace pour lutter contre l'écrasement, l'étanchéité n'est néanmoins pas optimale du fait de la déformation du joint au niveau de la pièce de raccordement. En effet, le joint arrière du capot est un joint présentant généralement une section circulaire (tubing) qui, pour assurer une étanchéité optimale, n'admet pas de déformation de sa surface d'appui. Thus, the document FR2668568 proposes to bypass the joint. Indeed this document describes a seal for a motor vehicle having an integrated conduit which extends parallel to the longitudinal direction of the seal. This duct is obtained by molding at the same time as the seal. It can be used to transport the washer fluid. Therefore, it is no longer necessary for the dispensing pipe to free the seal since it is integrated therein. Nevertheless, this solution involves the use of special seals and structural modifications of the washing liquid distribution circuit. JP2008025797 discloses a device to prevent crushing the windshield washer fluid distribution pipe through the hood seal when the pipe is stuck between the hood and the gasket. To do this, it is proposed to fix on the cover, at the joint, a connecting piece having a cross section of generally semi-elliptical general shape. This connecting piece is made of elastic material and deforms under the effect of the seal pressure to avoid generating free spaces at its lateral ends between the cover and the seal. The openings thus created would indeed be detrimental to the tightness of the assembly. It has a flat surface provided with fastening means which is intended to be glued or hung on the cover and a convex surface intended to cooperate with the seal to ensure tightness during closure of the cover. It further comprises an inner duct extending on either side of the piece in the form of end pieces. The washer fluid distribution pipe is cut in half. Each end of the pipe is connected to a tip of the connecting piece. The windshield washer fluid thus passes through the connecting piece. The connecting piece has a resistance to crushing by the seal greater than that of the distribution pipe and its shape is adapted to cooperate with it to ensure sealing. If this solution seems effective in the fight against crushing, the seal is nevertheless not optimal because of the deformation of the seal at the connection piece. Indeed, the rear seal of the hood is a seal generally having a circular section (tubing) which, to ensure optimum sealing, does not allow deformation of its bearing surface.
Afin de prévenir l'écrasement du tuyau, il est également connu de l'art antérieur de réaliser un embouti sur la doublure du capot du véhicule au niveau du joint d'étanchéité. Le tuyau de distribution est généralement retenu par clipsage à l'intérieur de cet embouti au moyen d'une pièce de fixation ayant le double rôle de maintenir le tuyau de distribution et d'assurer l'étanchéité du système. L'écrasement du tuyau est prévenu par une telle disposition puisque le joint arrière du capot ne pénètre pas dans l'embouti. Néanmoins, l'étanchéité du dispositif n'est pas optimale et des fuites ont été constatées, ce qui génère un risque de court circuit aggravé dans le moteur. L'invention propose d'apporter une solution au manque d'étanchéité constaté lorsque le tuyau de distribution lave-vitre traverse un embouti réalisé sur la doublure du capot. A cet effet, l'invention a pour objet un dispositif de raccordement pour un tuyau de distribution de liquide lave-vitre apte à être placé dans un embouti de la doublure du capot d'un véhicule, ladite doublure servant de surface d'appui à un joint d'étanchéité, ledit dispositif comprenant une face plane et une face présentant un renflement traversé par un conduit remarquable en ce que le renflement est destiné à être placé dans l'embouti et sa face plane est destinée à venir affleurer la surface de la doublure de capot afin de servir de surface d'appui pour le joint d'étanchéité sans le déformer de manière ponctuelle. To prevent the crushing of the pipe, it is also known from the prior art to make a stamping on the lining of the hood of the vehicle at the seal. The distribution pipe is generally held by clipping inside this stamping by means of a fastener having the dual role of maintaining the distribution pipe and sealing the system. The crushing of the pipe is prevented by such an arrangement since the rear seal of the hood does not penetrate the stamping. However, the seal of the device is not optimal and leaks were found, which generates a risk of short circuit aggravated in the engine. The invention proposes to provide a solution to the lack of tightness found when the windshield washer distribution pipe passes through a stamped formed on the lining of the hood. For this purpose, the invention relates to a connection device for a windshield washer fluid distribution pipe adapted to be placed in a stamping of the lining of the hood of a vehicle, said lining acting as a support surface for a seal, said device comprising a planar face and a face having a bulge crossed by a remarkable duct in that the bulge is intended to be placed in the stamping and its planar face is intended to come flush with the surface of the bonnet liner to serve as a support surface for the seal without deforming it in a timely manner.
De préférence, le dispositif comprend en outre au moins une aile latérale présentant un moyen de fixation saillant s'étendant du côté de la face présentant le renflement, de préférence encore il comprend deux ailes latérales chacune munie d'un moyen de fixation.  Preferably, the device further comprises at least one lateral wing having a projecting fastening means extending on the side of the face having the bulge, more preferably it comprises two lateral wings each provided with a fixing means.
De manière optionnelle, le conduit qui traverse le renflement se prolonge de part et d'autre du renflement sous forme d'embouts.  Optionally, the conduit that passes through the bulge extends on either side of the bulge in the form of end caps.
Selon un mode de réalisation préféré de l'invention, le corps présente en outre une lèvre périphérique souple. De préférence, la lèvre périphérique présente à sa base la même épaisseur que les ailes auxquelles elle est fixée. De préférence encore, la lèvre périphérique suit le contour de la face présentant un renflement du dispositif  According to a preferred embodiment of the invention, the body further has a flexible peripheral lip. Preferably, the peripheral lip has at its base the same thickness as the wings to which it is attached. More preferably, the peripheral lip follows the contour of the face having a bulge of the device
Selon un mode de réalisation préféré de l'invention, le dispositif est moulé en matériau élastomère, de préférence en EPDM. Optionnellement, les moyens de fixation et/ou le conduit sont réalisés en matériau plastique rigide et préférentiellement en polypropylène. According to a preferred embodiment of the invention, the device is molded of elastomeric material, preferably EPDM. Optionally, the fixing means and / or the conduit are made of rigid plastic material and preferably of polypropylene.
Selon un autre mode de réalisation préféré de l'invention, le conduit et les moyens de fixation sont formés d'une seule pièce en plastique rigide sur lesquels sont surmoulés en matériau élastomère le corps dudit dispositif, les ailes et de préférence la lèvre périphérique. On aura compris que l'invention consiste à obstruer de manière étanche l'embouti formé dans doublure du capot au moyen d'un dispositif de raccordement qui est traversé par un conduit aux extrémités duquel se raccorde le tuyau de distribution de liquide lave-vitre. L'invention s'attache en premier lieu à combler l'espace existant entre le dispositif de raccordement et le joint d'étanchéité tout en évitant une déformation éventuelle dudit joint. La mise en œuvre de l'invention consiste donc à fournir une surface d'appui plane pour le joint d'étanchéité au niveau du passage du tuyau de distribution de liquide lave-vitre. La surface d'appui du dispositif de raccordement selon l'invention affleure la surface plane d'appui fournie par la doublure du capot pour coopérer avec le joint d'étanchéité. De plus, la surface d'appui du dispositif de raccordement selon l'invention n'excède pas la surface plane d'appui fournie par la doublure du capot pour coopérer avec le joint d'étanchéité. En second lieu, l'invention s'attache à combler ou à sceller le jeu mécanique résultant de l'ajustement du dispositif de raccordement dans l'embouti de la doublure du capot. La mise en œuvre de l'invention consiste fixer hermétiquement le dispositif de raccordement dans l'embouti de la doublure du capot. Autrement dit, le dispositif de raccordement est pourvu d'un joint périphérique. According to another preferred embodiment of the invention, the conduit and the fixing means are formed of a single piece of rigid plastic on which are molded elastomeric material body of said device, the wings and preferably the peripheral lip. It will be understood that the invention consists in sealing the seal formed in the liner of the hood by means of a connecting device which is traversed by a pipe at the ends of which is connected the windshield washer fluid distribution pipe. The invention is primarily to fill the space between the connecting device and the seal while avoiding any deformation of said seal. The implementation of the invention is therefore to provide a flat bearing surface for the seal at the passage of the windshield washer fluid distribution pipe. The bearing surface of the connecting device according to the invention is flush with the flat bearing surface provided by the lining of the cover to cooperate with the seal. In addition, the bearing surface of the connecting device according to the invention does not exceed the flat bearing surface provided by the lining of the cover to cooperate with the seal. Secondly, the invention seeks to fill or seal the mechanical clearance resulting from the adjustment of the connection device in the stamping of the hood liner. The implementation of the invention consists of sealing the connection device in the stamping of the hood lining. In other words, the connecting device is provided with a peripheral seal.
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 a déjà été commentée dans la partie introductive. L'invention va maintenant être décrite en référence aux figures 2 et 3 qui présentent un exemple de dispositif (1 1 ) de raccordement selon l'invention apte à être utilisé pour la fixation d'un tuyau de distribution (7) de liquide lave-vitre d'un véhicule automobile, et à la figure 4 qui présente en coupe le dispositif (1 1 ) disposé entre la doublure (3) du capot et le joint d'étanchéité (9), dans l'embouti (23) de la doublure (3) de capot. Figure 1 has already been commented on in the introductory part. The invention will now be described with reference to FIGS. 2 and 3 which show an example of a connecting device (1 1) according to the invention suitable for use in fixing a dispensing pipe (7) for washing liquid. window of a motor vehicle, and in Figure 4 which presents in section the device (1 1) disposed between the lining (3) of the cover and the seal (9) in the stamping (23) of the lining (3) hood.
On comprendra néanmoins que ce dispositif peut également être utilisé pour la fixation de tuyaux destinés à transporter d'autres types de liquides ou de fluides tels que des gaz ou des éléments solides tels que par exemple des câbles. Le contenant du tuyau raccordé au dispositif de distribution (1 1 ) selon l'invention ne saurait constituer une limitation de l'invention. It will be understood, however, that this device can also be used for fixing pipes intended to carry other types of liquids or fluids such as gases or solid elements such as for example cables. The container of the pipe connected to the dispensing device (1 1) according to the invention can not constitute a limitation of the invention.
Le dispositif (1 1 ) de raccordement selon l'invention se présente sous la forme d'un corps de section sensiblement semi-cylindrique présentant au moins une aile (13) et de préférence deux ailes (13) disposées symétriquement de part et d'autre dudit corps. Le dispositif (1 1 ) présente une face d'appui (15) plane et une face (17) présentant un arrondi ou renflement (19). Il va sans dire que la face (15) plane est constituée de la surface du corps et des ailes (13) disposées en continuité et est destinée à servir de surface d'appui pour le joint (9) d'étanchéité. On notera que la forme du renflement (19) ne saurait être limitative quand à la portée de l'invention. On aura compris que la forme prise par le dispositif (1 1 ) de raccordement selon l'invention est avant tout complémentaire de la forme de l'embouti (23) de la doublure (3) du capot dans laquelle il s'emboîte. Ainsi la section du dispositif peut avoir par exemple une forme sensiblement semi-circulaire, semi-elliptique ou encore même trapézoïdale. L'essentiel pour le dispositif de raccordement selon l'invention est de présenter une face plane (15) et une face (17) présentant un renflement (19) longitudinal de forme complémentaire à la forme de l'embouti (23) et au travers duquel va passer un conduit (21 ) de distribution du liquide.  The connecting device (1 1) according to the invention is in the form of a substantially semi-cylindrical section body having at least one wing (13) and preferably two wings (13) arranged symmetrically on both sides. other of said body. The device (1 1) has a flat bearing face (15) and a face (17) having a rounding or bulge (19). It goes without saying that the flat face (15) consists of the surface of the body and the flanges (13) arranged in continuity and is intended to serve as a bearing surface for the seal (9) sealing. It will be noted that the shape of the bulge (19) can not be limiting when within the scope of the invention. It will be understood that the shape taken by the connecting device (1 1) according to the invention is above all complementary to the shape of the stamping (23) of the lining (3) of the cover in which it fits. Thus the section of the device may have for example a substantially semi-circular, semi-elliptical or even trapezoidal shape. The essential point for the connecting device according to the invention is to present a plane face (15) and a face (17) having a longitudinal bulge (19) of shape complementary to the shape of the stamping (23) and through which will pass a conduit (21) for dispensing the liquid.
Le dispositif (1 1 ) est réalisé en un matériau élastique souple comme un élastomère par exemple de l'EPDM (Ethylène-Propylène-Diène Monomère). Il peut être au choix intégralement réalisé en EPDM par moulage ou comme nous le verrons plus loin constitué de l'assemblage de deux pièces l'une en EPDM et l'autre en matériau plus rigide comme le Polypropylène.  The device (1 1) is made of a flexible elastic material such as an elastomer, for example EPDM (Ethylene-Propylene-Diene Monomer). It can be either entirely made of EPDM by molding or as we shall see later consisting of the assembly of two parts one EPDM and the other more rigid material such as polypropylene.
La face plane (15) ou face d'appui sera celle qui sera visible par l'utilisateur lorsque le dispositif de raccordement (1 1 ) est positionné sur la doublure (3) du capot. Avantageusement, comme on peut le voir sur la figure 4, la surface plane (15) du dispositif (1 1 ) se trouve au même niveau que la face supérieure de la doublure (3) du capot destinée à coopérer avec le joint d'étanchéité (9) lorsque le dispositif (1 1 ) est fixé. C'est-à-dire que la surface plane (15) du dispositif affleure sans l'excéder la surface plane de la doublure (3) du capot qui sert de surface d'appui au joint d'étanchéité (9). On comprendra sans peine qu'ainsi la surface plane du dispositif (1 1 ) selon l'invention sert de surface d'appui au joint (9) et se place en continuité de la surface d'appui de la doublure (3) du capot de telle sorte à ce que le joint d'étanchéité (9) ne se déforme pas à son contact. De plus, le dispositif de raccordement (1 1 ) ne présente pas, sur sa surface faisant face au joint (9), d'évidement qui pourrait offrir un passage à l'eau. Le dispositif de raccordement (1 1 ) coopère donc avec le joint d'étanchéité (9) au même titre et de la même façon que la doublure (3) du capot pour assurer l'étanchéité arrière du capot (1 ). On rappelle au besoin que le joint arrière (9) du capot est généralement un joint à section circulaire qui assure l'étanchéité en s'écrasant sur une surface la plus plane possible. Ce qui veut dire que le joint (9) n'admet qu'une déformation infinitésimale de la surface d'appui, sans cela il ne rempli pas sa fonction. De même, il ne lui est pas aisé de pénétrer dans un évidement de la surface sur laquelle il s'écrase. Le dispositif de raccordement pour un tuyau de distribution de liquide lave-vitre selon l'invention est donc apte à être placé dans un embouti de la doublure du capot d'un véhicule, ladite doublure servant de surface d'appui à un joint d'étanchéité, il comprend une face plane et une face présentant un renflement traversé par un conduit et est remarquable en ce que le renflement présente une forme complémentaire de la forme de l'embouti de telle sorte que lorsque le dispositif est placé dans l'embouti sa face plane vient affleurer la surface de la doublure de capot afin de servir de surface d'appui pour le joint d'étanchéité sans le déformer. The flat face (15) or bearing face will be the one that will be visible to the user when the connecting device (1 1) is positioned on the lining (3) of the cover. Advantageously, as can be seen in FIG. 4, the flat surface (15) of the device (1 1) is at the same level as the upper face of the lining (3) of the cover intended to cooperate with the seal (9) when the device (1 1) is fixed. That is to say that the flat surface (15) of the device is flush without exceeding the flat surface of the lining (3) of the cover which serves as a bearing surface for the seal (9). It will be readily understood that the flat surface of the device (1 1) according to the invention serves as a bearing surface for the seal (9) and is placed in continuity with the bearing surface of the lining (3) of the hood so that the seal (9) does not deform on contact. In addition, the connecting device (1 1) does not have a recess on its surface facing the seal (9) which could provide a passage to the water. The connecting device (1 1) therefore cooperates with the seal (9) in the same way and in the same way as the lining (3) of the cover to ensure the rear seal of the cover (1). It is recalled that if necessary the rear seal (9) of the cover is generally a circular section seal which seals by crashing on a surface as flat as possible. This means that the seal (9) admits only infinitesimal deformation of the bearing surface, otherwise it does not fulfill its function. In the same way, it is not easy for him to penetrate into a recess of the surface on which he crashes. The connection device for a windshield washer fluid distribution pipe according to the invention is therefore suitable for being placed in a stamped part of the lining of the hood of a vehicle, said lining acting as a support surface for a gasket. sealing, it comprises a flat face and a face having a bulge through which a conduit and is remarkable in that the bulge has a shape complementary to the shape of the stamped so that when the device is placed in the stamped its plane face is flush with the surface of the bonnet liner to serve as a bearing surface for the seal without deforming it.
Les ailes (13) du dispositif de raccordement (9) présentent avantageusement au moins un moyen de fixation (25) saillant s'étendant du coté de la face (17) présentant le renflement (19) en direction de la doublure (3) de capot. Les moyens de fixation (25) sont destinés à coopérer avec des moyens présents sur la doublure (3) du capot pour y assurer le positionnement et la fixation du dispositif de raccordement (1 1 ). Lorsque le dispositif (1 1 ) est intégralement réalisé en EPDM, ce moyen de fixation (25) peut être un téton saillant qui coopère avec un trou (non représenté) présent dans l'embouti (23) de la doublure (3) du capot en vue d'un emboîtage élastique de type « bouton- pression ». Néanmoins, l'homme du métier peut également envisager d'autres moyens de fixation. The wings (13) of the connecting device (9) advantageously have at least one projecting fastening means (25) extending on the side of the face (17) presenting the bulge (19) in the direction of the lining (3) of cover. The fixing means (25) are intended to cooperate with means present on the lining (3) of the cover to ensure the positioning and fixing of the connecting device (1 1). When the device (1 1) is integrally made of EPDM, this fixing means (25) may be a projecting stud which cooperates with a hole (not shown) present in the stamping (23) the lining (3) of the hood for an elastic "push-button" type casing. Nevertheless, those skilled in the art may also consider other means of attachment.
Ainsi, dans un mode de réalisation préféré de l'invention, le moyen de fixation (25) du dispositif de raccordement (1 1 ) est en plastique moins souple, tel que du Polypropylène (PP). Dans ce cas on aura un dispositif de raccordement (1 1 ) non plus d'une seule pièce mais résultant de l'assemblage d'au moins deux pièces. De préférence, le moyen de fixation (25) prend la forme d'une languette à encliqueter. La fixation du dispositif (1 1 ) sur la doublure (3) du capot se fera alors par encliquetage. Ce mode de réalisation offre l'avantage de générer un petit bruit lors de la mise en place du dispositif (1 1 ) qui indique aux personnes installant le dispositif qu'il a bien été fixé.  Thus, in a preferred embodiment of the invention, the fastening means (25) of the connecting device (1 1) is less flexible plastic, such as polypropylene (PP). In this case we will have a connecting device (1 1) no longer in one piece but resulting from the assembly of at least two parts. Preferably, the fastening means (25) takes the form of a snap-on tongue. Fixing the device (1 1) on the lining (3) of the cover will then snap. This embodiment has the advantage of generating a small noise during the introduction of the device (1 1) which indicates to people installing the device that it has been fixed.
Le renflement (19) du corps du dispositif (1 ) est, comme nous l'avons vu, traversé longitudinalement par un conduit (21 ). Ce conduit (21 ) débouche de part et d'autre du dispositif au niveau des bases du semi-cylindre formé par le renflement (19). Le conduit (21 ) se prolonge préférentiellement au-delà des ces bases par des embouts (27) aptes à être connectés chacun à une extrémité du tuyau (7) de distribution du liquide lave- vitre. En effet, le dispositif de raccordement (1 1 ) va se substituer au tuyau (7) de distribution du liquide au niveau du passage du joint d'étanchéité (9). Le tuyau (7) est donc coupé en deux pour se raccorder de part et d'autre du dispositif de raccordement (1 1 ). Le conduit (21 ) et ses embouts (27) saillants peuvent être réalisés en EDPM ou en PP, à la convenance de l'homme du métier. Il est à noter que grâce au fait que le dispositif de raccordement (1 1 ) est intercalé entre un embouti (23) de la doublure (3) du capot et le joint (9), la pression exercée sur lui par le joint (9) ne conduira pas à un écrasement du conduit (21 ). En effet, la surface plane (15) du dispositif (1 1 ) est au même niveau que la surface plane de la doublure (3) du capot, de ce fait la pression du joint (9) ne conduit pas à une déformation du dispositif de raccordement (1 1 ). La mise en œuvre d'un conduit (21 ) en PP est néanmoins préférée pour faciliter le raccordement du tuyau (7) de distribution de liquide lave-vitre. De préférence, les moyens de fixation (25) et le conduit (21 ) en PP seront d'une seule pièce, le reste du dispositif sera surmoulé en EPDM. Selon une mise en œuvre préférée de l'invention, l'étanchéité de l'ensemble est encore renforcée par la présence sur le dispositif de raccordement (1 1 ) d'un joint sous forme d'une lèvre (29) périphérique qui va sceller le jeu mécanique résultant de l'ajustement du dispositif (1 1 ) dans l'embouti (23) de la doublure (3) du capot. Cette lèvre (29) périphérique suit les contours de l'embouti (23) et donc des contours définis par la face (17) du dispositif (1 1 ). C'est-à-dire notamment qu'elle va passer sous les extrémités ou embouts (27) du conduit (21 ) traversant le dispositif (1 1 ). De préférence la lèvre (29) périphérique présente à sa base la même épaisseur que les ailes latérales (13) du dispositif (1 1 ) auxquelles elle est fixée. On aura compris que la lèvre (29) périphérique ne fait qu'un avec le corps du dispositif (1 1 ) et est donc réalisée en EPDM. The bulge (19) of the body of the device (1) is, as we have seen, traversed longitudinally by a conduit (21). This duct (21) opens on either side of the device at the bases of the semi-cylinder formed by the bulge (19). The duct (21) is preferably extended beyond these bases by end pieces (27) each capable of being connected to one end of the pipe (7) for dispensing the washing-glass liquid. Indeed, the connecting device (1 1) will replace the pipe (7) for dispensing the liquid at the passage of the seal (9). The pipe (7) is thus cut in half to connect on both sides of the connecting device (1 1). The duct (21) and its tips (27) projecting can be made in EDPM or PP, at the convenience of the skilled person. It should be noted that thanks to the fact that the connecting device (1 1) is interposed between a stamp (23) of the lining (3) of the cover and the seal (9), the pressure exerted on it by the seal (9) ) will not lead to a crushing of the duct (21). Indeed, the flat surface (15) of the device (1 1) is at the same level as the flat surface of the lining (3) of the cover, therefore the pressure of the seal (9) does not lead to a deformation of the device connection (1 1). The implementation of a duct (21) made of PP is nevertheless preferred to facilitate the connection of the pipe (7) for dispensing washer fluid. Preferably, the fastening means (25) and the conduit (21) made of PP will be in one piece, the rest of the device will be overmolded in EPDM. According to a preferred embodiment of the invention, the tightness of the assembly is further enhanced by the presence on the connecting device (1 1) of a seal in the form of a peripheral lip (29) which will seal the mechanical clearance resulting from the adjustment of the device (1 1) in the stamping (23) of the lining (3) of the cover. This lip (29) peripheral follows the contours of the stamping (23) and thus the contours defined by the face (17) of the device (1 1). That is to say that it will pass under the ends or ends (27) of the conduit (21) passing through the device (1 1). Preferably the peripheral lip (29) has at its base the same thickness as the lateral wings (13) of the device (1 1) to which it is attached. It will be understood that the peripheral lip (29) is one with the body of the device (1 1) and is therefore made of EPDM.
La présence de la lèvre (29) périphérique en extension des ailes (13) permet de combler le jeu mécanique entre le dispositif (1 1 ) et la doublure (3) du capot. En effet, il a été montré par l'inventeur que ce jeu s'étendant longitudinalement forme avec le joint d'étanchéité (9) un petit canal parallèle au conduit (21 ) du dispositif (1 1 ) et susceptible de laisser passer l'eau lorsqu'il n'est pas comblé par la lèvre (9). La poursuite de la lèvre (9) périphérique le long du contour de la face (17) permet de sceller le jeu résultant de l'ajustement du dispositif (1 1 ) dans l'embouti (23) de la doublure (3) du capot.  The presence of the peripheral lip (29) in extension of the wings (13) makes it possible to fill the mechanical clearance between the device (1 1) and the lining (3) of the cover. Indeed, it has been shown by the inventor that this game extending longitudinally forms with the seal (9) a small channel parallel to the conduit (21) of the device (1 1) and likely to pass the water when not filled by the lip (9). The pursuit of the peripheral lip (9) along the contour of the face (17) seals the clearance resulting from the adjustment of the device (1 1) in the stamping (23) of the lining (3) of the hood .
De ce fait, lorsque le capot (1 ) est fermé, il ne reste plus de passage possible pour l'eau autour du dispositif (1 1 ). Puisque le dispositif (1 1 ) est fixé hermétiquement sur la doublure (3) du capot grâce à la lèvre (29) sur sa face (17) et ses côtés, et que l'étanchéité avec le joint (9) est assurée au niveau de sa face d'appui (15) du fait de sa surface plane affleurante.  As a result, when the hood (1) is closed, there is no longer any passage for the water around the device (1 1). Since the device (1 1) is hermetically fixed on the lining (3) of the hood with the lip (29) on its face (17) and its sides, and that the seal with the seal (9) is ensured at its bearing face (15) due to its flush flat surface.
Le dispositif (1 1 ) selon l'invention peut donc présenter deux niveaux d'étanchéité. Un premier niveau d'étanchéité est représenté par la surface plane (15) et un second niveau d'étanchéité est donné par la lèvre périphérique (29) qui suit la courbure de l'embouti (23) et donc de la face (17) du dispositif (1 1 ).  The device (1 1) according to the invention can therefore have two levels of sealing. A first level of sealing is represented by the flat surface (15) and a second level of sealing is given by the peripheral lip (29) which follows the curvature of the stamp (23) and therefore of the face (17). of the device (1 1).
L'invention est remarquable en ce qu'elle permet au tuyau (7) de distribution du liquide lave-vitre de franchir le joint (9) arrière de capot (1 ) sans en altérer l'étanchéité. L'invention permet de préserver à la fois l'étanchéité à l'eau, aux bruits et aux odeurs tout en supprimant les risques de court circuit aggravé. Par ailleurs, Le dispositif (1 1 ) de l'invention permet d'assurer le positionnement du tuyau (7) de distribution. En effet, celui-ci n'est plus clippé dans un dispositif de fixation mais raccordé à une pièce. Il ne risque donc plus de glisser ou de bouger, sa position est donc assurée ce qui offre une amélioration d'un point de vue du montage du dispositif de projection de liquide lave-vitre. The invention is remarkable in that it allows the pipe (7) for dispensing the windshield washer fluid to cross the seal (9) rear bonnet (1) without altering the seal. The invention preserves both watertightness, noise and odors while eliminating the risk of aggravated short circuit. Furthermore, the device (1 1) of the invention ensures the positioning of the pipe (7) distribution. Indeed, it is no longer clipped into a fastener but connected to a room. It is therefore no longer risk of slipping or moving, its position is therefore ensured which offers an improvement from a point of view of mounting the windscreen washer spraying device.
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.  The invention is not limited to the embodiments described above only by way of example, but encompasses all the variants that may be considered by those skilled in the art within the scope of the definition that has been given.
