Description

DISPOSITIF DE CONNEXION D'UN SYSTEME D'ESSUYAGE  DEVICE FOR CONNECTING A WIPING SYSTEM
Le domaine de la présente invention est celui des équipements pour les véhicules, et plus particulièrement celui des équipements pour l'essuyage des 5 vitrages des automobiles. The field of the present invention is that of equipment for vehicles, and more particularly that of equipment for wiping the windows of automobiles.
Les automobiles sont couramment équipées de systèmes d'essuie-glace pour assurer un lavage du pare-brise et éviter que la vision qu'a le conducteur de son environnement soit perturbée. Ces essuie-glaces sont classiquement entraînés par un bras effectuant un mouvement de va-et-vient angulaire et î o comportent des balais allongés, porteurs eux-mêmes de lames racleuses réalisées en une matière élastique. Ces lames frottent contre le pare-brise et évacuent l'eau en l'amenant en dehors du champ de vision du conducteur. Les balais sont réalisés sous la forme, soit, dans une version classique, d'étriers articulés qui tiennent la lame racleuse en plusieurs endroits discrets, soit, dans Automobiles are commonly equipped with wiper systems to wash the windshield and prevent the driver's vision from being disturbed. These windscreen wipers are conventionally driven by an arm performing an angular reciprocating movement and they comprise elongated brushes, themselves carrying scraping blades made of an elastic material. These blades rub against the windshield and evacuate the water by bringing it out of the driver's field of vision. The brooms are made in the form, or, in a conventional version, articulated stirrups that hold the scraper blade in several discrete places, or, in
15 une version plus récente dénom mée "flat blade" (pour "lame plate"), d'un ensemble semi-rigide qui maintient la lame racleuse sur toute sa longueur. Dans les deux solutions, le balai est rattaché au bras tournant de l'essuie-glace par un ensemble constitué d'un connecteur et d'un adaptateur. Ces deux pièces sont reliées l'une à l'autre par un axe transversal qui autorise leur rotation relative,15 a more recent version called "flat blade" (for "flat blade"), a semi-rigid assembly that keeps the scraper blade along its entire length. In both solutions, the blade is attached to the rotating arm of the wiper by a set consisting of a connector and an adapter. These two parts are connected to each other by a transverse axis which allows their relative rotation,
20 dans un plan perpendiculaire au pare-brise passant par le bras. 20 in a plane perpendicular to the windshield passing through the arm.
Les essuie-glaces sont également équipés de dispositifs d'amenée d'un liquide lave-vitre qui est acheminé depuis un réservoir situé sur le véhicule et qui est pulvérisé en direction du pare-brise par des buses situées soit autour du pare- brise, soit sur l'essuie-glace lui-même pour une meilleure distribution du liquide. The wipers are also equipped with devices for supplying a windscreen washer fluid which is conveyed from a tank located on the vehicle and which is sprayed towards the windscreen by nozzles located around the windscreen, either on the windscreen wiper itself for a better distribution of the liquid.
25 Dans le cas de buses placées sur les balais, le liquide lave-vitre est acheminé, avant d'être réparti entre elles, par des canalisations qui sont fixées sur le bras de l'essuie-glace et qui sont raccordées au système de distribution du balai au niveau du connecteur. In the case of nozzles placed on the brushes, the window washer fluid is conveyed, before being distributed between them, by pipes which are fixed on the arm of the windscreen wiper and which are connected to the distribution system. broom at the connector.
Sur des modèles pour véhicules de haut de gamme, on trouve également On models for high-end vehicles, we also find
30 des dispositifs de chauffage de l'essuie-glace pour dégeler le balai en cas de grand froid et éviter qu'il colle au pare-brise sous l'action du gel. Ces dispositifs, qui sont plus spécialement adaptés à des balais plats, comportent généralement un dispositif chauffant intégré dans l'ensemble porteur de la lame racleuse et sur laquelle sont déposées des résistances électriques. Ils nécessitent eux aussi un dispositif de connexion électrique, placé au niveau du connecteur, pour transmettre au dispositif chauffant le courant électrique provenant du véhicule. 30 wiper heating devices to thaw the broom in extreme cold and avoid it sticks to the windshield under the action of frost. These devices, which are more specifically adapted to flat brushes, generally comprise a heating device integrated in the carrier assembly of the scraper blade and on which electrical resistances are deposited. They also require an electrical connection device, placed at the connector, to transmit to the heating device the electric current from the vehicle.
II importe donc d'assurer la connexion électrique entre le fil d'alimentation porté pa r l e b ras d e l ' ess u i e-glace et le dispositif chauffant du balai correspondant, ainsi que la connexion hydraulique entre les canalisations portées par le bras et ce même balai.  It is therefore important to ensure the electrical connection between the supply wire carried by the ice-cream machine and the heating device of the corresponding broom, as well as the hydraulic connection between the pipes carried by the arm and the same broom. .
Le document WO2010/034447 montre un connecteur mécanique solidaire d'un bras et au travers duquel une alimentation électrique et un liquide passent. Un connecteur supplémentaire fournit en électricité et en liquide le connecteur mécanique. Le connecteur supplémentaire est inséré dans le connecteur mécanique selon une direction générale d'extension du balai. Pour assurer la liaison hydraulique, le connecteur mécanique présente un orifice d'admission du liquide qui s'étend dans une direction perpendiculaire à la direction générale d'extension du balai.  WO2010 / 034447 shows a mechanical connector secured to an arm and through which a power supply and a liquid pass. An additional connector supplies the mechanical connector with electricity and liquid. The additional connector is inserted into the mechanical connector in a general direction of extension of the blade. To provide the hydraulic connection, the mechanical connector has a liquid inlet which extends in a direction perpendicular to the general direction of extension of the blade.
L'inconvénient d'une telle structure réside dans la difficulté d'aligner les deux connecteurs en phase de montage du balai sur le bras. En effet, il est alors nécessaire de réaliser le montage mécanique du balai sur le bras tout en veillant à ce que le connecteur supplémentaire soit correctement instal lé dans le connecteur mécanique. Ceci complique le montage et par conséquent n'est pas ergonomique. Cet assemblage augmente également le risque d'absence ou de mauvais contact électrique et le risque de fuite par absence d'étanchéité entre les deux connecteurs.  The disadvantage of such a structure lies in the difficulty of aligning the two connectors in the assembly phase of the blade on the arm. Indeed, it is then necessary to perform the mechanical assembly of the blade on the arm while ensuring that the additional connector is properly installed in the mechanical connector. This complicates the assembly and therefore is not ergonomic. This assembly also increases the risk of absence or poor electrical contact and the risk of leakage due to lack of sealing between the two connectors.
II convient donc de trouver une solution plus ergonomique et qui garantisse la continuité électrique ainsi que l'étanchéité hydraul ique au n iveau de la connexion entre un bras et un balai d'essuie-glace.  It is therefore necessary to find a more ergonomic solution that guarantees electrical continuity as well as hydraulic sealing at the level of the connection between an arm and a wiper blade.
La présente invention a pour but de remédier à ces inconvénients en proposant un nouveau moyen de relier le balai au bras. Contrairement à l'art antérieur où l'orifice d'admission de l iquide du connecteur mécanique est perpendiculaire à la direction générale du balai, l'invention propose de localiser cet orifice de telle sorte qu'il présente une direction qui s'étend parallèlement à la direction générale d'extension du balai. L'étanchéité entre le connecteur hydraulique et le dispositif de connexion selon l'invention n'est ainsi pas assurée à l'arrière du dispositif de connexion mais sur le dessus de ce dernier, par exemple dans un plan parallèle à la direction générale d'extension du balai. The present invention aims to overcome these disadvantages by proposing a new way to connect the brush to the arm. Unlike the prior art where the liquid inlet of the mechanical connector is perpendicular to the general direction of the brush, the invention proposes to locate this orifice so that it has a direction that extends parallel to the general direction of extension of the broom. The seal between the hydraulic connector and the connection device according to the invention is thus not ensured at the rear of the connection device but on the top of the latter, for example in a plane parallel to the general direction of the connection. extension of the broom.
5 L' invention a donc pour objet un dispositif de connexion d'un système d'essuyage comprenant un bras, un balai et un connecteur hydraulique relié au bras, le dispositif de connexion comprend :  The invention therefore relates to a connection device of a wiper system comprising an arm, a blade and a hydraulic connector connected to the arm, the connection device comprises:
- un moyen de solidarisation apte à rendre le d ispositif de connexion solidaire du balai,  a securing means capable of making the connection device integral with the blade,
î o - un dispositif de fixation apte à relier le dispositif de connexion au connecteur hydraulique, î o - a fixing device adapted to connect the connection device to the hydraulic connector,
- au moins un canal de distribution d'un liquide qui s'étend selon une direction longitudinale, le canal comprenant un orifice d'admission, caractérisé en ce que l'orifice d'adm ission s'étend dans une direction parallèle à la direction at least one liquid distribution channel which extends in a longitudinal direction, the channel comprising an inlet orifice, characterized in that the admission orifice extends in a direction parallel to the direction
15 longitudinale. On comprend donc que, contrairement à l'art antérieur, la liaison hydraulique entre le dispositif de connexion et le connecteur hydraulique est assurée sur une face supérieure du dispositif de connexion, cette face supérieure s'étendant dans un plan qui contient au moins un droite parallèle à la direction longitudinale du canal. Cette dernière est quant à elle parallèle une directionLongitudinal. It is therefore understood that, contrary to the prior art, the hydraulic connection between the connection device and the hydraulic connector is provided on an upper face of the connection device, this upper face extending in a plane which contains at least one straight line. parallel to the longitudinal direction of the canal. The latter is parallel direction
20 longitudinale du balai. 20 longitudinal broom.
Selon une première caractéristique de l'invention, l'orifice d'admission forme un plan apte à recevoir un moyen d'étanchéité installé entre le dispositif de connexion et le connecteur hydraulique. Un joint est par exemple installé autour de l'orifice d'admission de sorte à garantir l'étanchéité hydraulique quand le According to a first characteristic of the invention, the inlet orifice forms a plane adapted to receive a sealing means installed between the connection device and the hydraulic connector. For example, a seal is installed around the intake opening to ensure the hydraulic seal when the
25 connecteur hydraulique est fixé sur le dispositif de connexion. 25 hydraulic connector is attached to the connection device.
Selon une deuxième caractéristique de l'invention, l'orifice d'admission est relié au canal de distribution du liquide par au moins un puits qui s'étend selon une direction concourante avec la direction longitudinale.  According to a second characteristic of the invention, the inlet orifice is connected to the liquid distribution channel by at least one well which extends in a direction concurrent with the longitudinal direction.
Selon encore une caractéristique de l'invention, le dispositif de fixation est According to another characteristic of the invention, the fixing device is
30 apte à assurer au moins un lien mécanique et une étanchéité hydraulique entre le connecteur hydraulique et le dispositif de connexion. Au surplus, le dispositif de fixation garantit le contact électrique entre le connecteur hydraulique et le dispositif de connexion de sorte à alimenter l'élément chauffant intégré au balai. Il assure donc également un lien électrique entre le dispositif de connexion et le connecteur hydraulique. 30 capable of ensuring at least one mechanical link and a hydraulic seal between the hydraulic connector and the connection device. In addition, the fixing device ensures the electrical contact between the hydraulic connector and the connecting device so as to power the heating element integrated in the broom. It also ensures an electrical connection between the connection device and the hydraulic connector.
Selon encore une autre caractéristique de l'invention, le dispositif de fixation 5 est amovible selon un déplacement en rotation du connecteur hydraulique par rapport au dispositif de connexion.  According to yet another characteristic of the invention, the fixing device 5 is removable according to a rotational displacement of the hydraulic connector relative to the connection device.
Le dispositif de fixation comprend au moins une gorge et au moins un clip. The fixing device comprises at least one groove and at least one clip.
Avantageusement, l'orifice d'admission est installé entre la gorge et le clip. Cette disposition garantit un effort mécanique de pression qui assure l'étanchéité. î o Avantageusement encore, le dispositif de connexion comprend en outre un dispositif conducteur d'électricité destiné à relier électriquement le connecteur hydraulique à un élément chauffant intégré au balai. Advantageously, the intake port is installed between the groove and the clip. This arrangement ensures a mechanical pressure force which ensures sealing. Advantageously, the connection device further comprises an electrically conductive device for electrically connecting the hydraulic connector to a heating element integrated in the brush.
Selon une première caractéristique de l'invention, le dispositif conducteur d'électricité comprend au moins un point de contact électrique avec le connecteur 15 hydraulique. De manière préférentielle, le point de contact étant installé entre la gorge et le clip.  According to a first characteristic of the invention, the electrically conductive device comprises at least one point of electrical contact with the hydraulic connector. Preferably, the point of contact being installed between the groove and the clip.
Selon une deuxième caractéristique de l'invention, le moyen de solidarisation est inamovible. On comprend ici que le moyen de solidarisation établit un lien mécanique indémontable entre le balai et le dispositif de connexion. 20 L'invention vise également un balai d'un système d'essuyage comprenant un dispositif de connexion selon l'une quelconque des caractéristiques évoquées ci- dessus.  According to a second characteristic of the invention, the securing means is irremovable. It is understood here that the securing means establishes an indémontable mechanical link between the brush and the connection device. The invention also relates to a wiper of a wiper system comprising a connecting device according to any one of the characteristics mentioned above.
Enfin, l'invention couvre un système d'essuyage comprenant un bras, un balai, un connecteur hydraulique et un adaptateur intercalé entre le bras et le 25 connecteur hydraulique, caractérisé en ce qu' il com prend un dispositif de connexion selon l'une quelconque des particularités indiquées précédemment.  Finally, the invention covers a wiper system comprising an arm, a broom, a hydraulic connector and an adapter inserted between the arm and the hydraulic connector, characterized in that it comprises a connection device according to one of any of the features indicated above.
Dans ce système, le balai présente au moins un degré de liberté en rotation par rapport au bras selon un axe de rotation, cet axe de rotation étant réalisé par le connecteur hydraulique.  In this system, the blade has at least one degree of freedom in rotation relative to the arm along an axis of rotation, this axis of rotation being formed by the hydraulic connector.
30 On notera que le connecteur hydraulique et le dispositif de connexion sont isostatiques quand ils sont reliés ou assemblés par le dispositif de fixation. It should be noted that the hydraulic connector and the connection device are isostatic when they are connected or assembled by the fixing device.
Un avantage qui découle de l'invention réside dans la facilité de montage et de démontage du balai vis-à-vis du bras. Le raccordement et l'étanchéité en liquide lave vitre entre le dispositif de connexion et le connecteur hydraulique sont assurés en même temps que l'opération de montage du balai sur le bras. Il n'existe donc plus de difficulté pour aligner et enfiler les différents composants, ce 5 positionnement étant garantit par des formes conjuguées entre le dispositif de connexion et le connecteur hydraulique. One advantage of the invention lies in the ease of assembly and disassembly of the blade vis-à-vis the arm. The connection and sealing of windshield washer fluid between the connecting device and the hydraulic connector are provided at the same time as the operation of mounting the blade on the arm. There is thus no longer any difficulty in aligning and threading the various components, this positioning being ensured by the combined shapes between the connecting device and the hydraulic connector.

Il faut noter que les figures exposent l'invention de manière détaillée, lesdites figures pouvant bien entendu servir à mieux définir l'invention le cas échéant.  It should be noted that the figures disclose the invention in detail, said figures can of course be used to better define the invention where appropriate.
La figure 1 illustre un système d'essuyage comprenant un bras 1 présentant 30 une extrémité 2, autrement appelé chape. Cette extrémité supporte un balai 3 qui peut être du type à palonniers ou de type plat, connu de l'anglais « flat blade ». Ce balai comprend un élément chauffant qui prend la forme d'une piste résistive qui chemine sur un support du balai. Une alimentation en liquide lave-vitre 4 prend la forme d'un tuyau qui court le long du bras 1 jusqu'à l'extrémité 2 de ce dernier, où un connecteur hydraulique et un dispositif de connexion selon l'invention sont installés. Figure 1 illustrates a wiper system comprising an arm 1 having an end 2, otherwise called a yoke. This end supports a broom 3 which can be of the type with rudder or flat type, known as "flat blade". This broom includes a heating element which takes the form of a resistive track who walks on a broom stand. A windshield washer fluid supply 4 takes the form of a pipe that runs along the arm 1 to the end 2 of the latter, where a hydraulic connector and a connection device according to the invention are installed.
5 Pour permettre au balai de suivre la courbure du pare-brise à essuyer, le balai 3 présente au moins un degré de liberté en rotation par rapport au bras 1 , et plus spécifiquement par rapport à l'extrémité 2, selon un axe de rotation symbolisé par la référence 23. Le balai 3 doit ainsi pouvoir tourner autour de cet axe de rotation 23.  To allow the blade to follow the curvature of the windshield to be wiped, the blade 3 has at least one degree of freedom in rotation with respect to the arm 1, and more specifically with respect to the end 2, along an axis of rotation. symbolized by the reference 23. The blade 3 must thus be able to rotate about this axis of rotation 23.
î o Le balai 3 s'étend principalement dans une direction 1 16 qualifiée de longitudinale en ce sens qu'elle est déterminée par la longueur du balai. Cette direction longitudinale 1 16 du balai est sensiblement orthogonale à l'axe de rotation 23. The brush 3 extends mainly in a direction 1 16 termed longitudinal in that it is determined by the length of the brush. This longitudinal direction 1 16 of the wiper is substantially orthogonal to the axis of rotation 23.
La figure 2 illustre l'extrémité 2 du bras term inée par une forme en « U », 15 c'est-à-dire comprenant une base 6 et deux branches latérales 7a et 7b délimitant ainsi un volume interne.  FIG. 2 illustrates the end 2 of the end arm in a "U" shape, that is to say comprising a base 6 and two lateral branches 7a and 7b thus delimiting an internal volume.
Un adaptateur 9 présente une forme complémentaire au volume interne, de sorte à venir se loger dans ce dernier. Cet adaptateur 9 comprend deux trous 24a et 24b chacun pratiqué au travers de ses parois latérales. Ces deux trous 24a et An adapter 9 has a shape complementary to the internal volume, so as to be housed in the latter. This adapter 9 comprises two holes 24a and 24b each made through its side walls. These two holes 24a and
20 24b présentent un axe confondu, cet axe étant également confondu avec l'axe de rotation 23 entre le balai et le bras quand le système d'essuyage intégrant le dispositif de connexion est assemblé. 24b have an axis coincident, this axis being also coincident with the axis of rotation 23 between the blade and the arm when the wiper system incorporating the connecting device is assembled.
Sur la figure 2, l'extrémité 2 du bras est illustrée en transparence. L'adaptateur 9 est logé dans la section en « U » formée par l'extrémité 2 et le trou 25 24a est en prise sur un arbre 25 constitutif d'un moyen de rotation entre l'adaptateur 9 et un connecteur hydraulique 5, ce moyen de rotation étant centré sur un axe confondu à l'axe de rotation 23 entre le bras et le balai.  In Figure 2, the end 2 of the arm is illustrated in transparency. The adapter 9 is housed in the "U" section formed by the end 2 and the hole 24a is engaged on a shaft 25 constituting a means of rotation between the adapter 9 and a hydraulic connector 5, which means of rotation being centered on an axis coinciding with the axis of rotation 23 between the arm and the blade.
Dans cet exem ple de réal isation, l'adaptateur 9 est verroui l lé dans l'extrémité 2 du bras par une languette 48 issue d'un plat supérieur 1 1 formant In this exemplary embodiment, the adapter 9 is locked in the end 2 of the arm by a tongue 48 coming from an upper plate 1 1 forming
30 l'adaptateur 9. Cette languette 48 dépasse du plan formé par le plat supérieur 1 1 de sorte à pénétrer dans un évidement 42 formé dans la base 6 de l'extrémité 2. On empêche ainsi le mouvement de translation entre l'adaptateur 9 et l'extrémité 2, tout en autonsant l'extraction du connecteur hydraulique 5 pour le remplacer quand celui-ci est détérioré. The tab 48 protrudes from the plane formed by the upper plate 1 1 so as to penetrate into a recess 42 formed in the base 6 of the end 2. This prevents the translational movement between the adapter 9. and the end 2, while autonsant the extraction of the hydraulic connector 5 to replace it when it is damaged.
Le dispositif de connexion 27 peut également être appelé connecteur mécanique. Il est qualifié ainsi car il est solidarisé de manière indémontable sur le 5 balai. Il assure ainsi la transmission de l'effort mécanique en provenance du bras 1 vers le balai 3. Ce dispositif de connexion 27 comprend ainsi un moyen de solidarisation sur le balai qui est inamovible. On comprend par ce terme que le moyen de solidarisation est fixé à demeure sur la structure du balai et qu'il ne comprend pas de moyen réversible lui permettant d'être démonté du balai. Il est î o donc inam ovi ble car son dém ontage entraîne une casse du m oyen de solidarisation ou du balai.  The connection device 27 may also be called a mechanical connector. It is so qualified because it is secured in a way that can not be dismantled on the broom. It thus ensures the transmission of the mechanical force from the arm 1 to the brush 3. This connection device 27 thus comprises a securing means on the brush which is irremovable. It is understood by this term that the securing means is fixed permanently on the structure of the brush and that it does not include reversible means allowing it to be removed from the brush. It is therefore immovable because its demage causes a breakage of the fastening means or the broom.
Ce dispositif de connexion 27 comprend deux canaux de distribution 29 et 30 (sur la figure 2, seul le canal 29 est visible) d'un liquide lave-vitre qui coopère avec des conduits de circulation de liquide du connecteur hydraulique 5. Ces This connection device 27 comprises two distribution channels 29 and 30 (in FIG. 2, only the channel 29 is visible) of a windshield washer fluid which cooperates with liquid circulation conduits of the hydraulic connector 5. These
15 canaux 29 et 30 s'étendent sur les côtés du connecteur mécanique 27, mais se poursuivent au centre de celui-ci et se term ine par un orifice d'admission du liquide. Ce dernier débouche au droit de chaque conduit de circulation de liquide du connecteur hydraulique. L'étanchéité au droit de l'orifice entre les conduits de circulation du connecteur hydraulique et les canaux de distribution 29 et 30 duChannels 29 and 30 extend along the sides of the mechanical connector 27, but continue in the center thereof and terminate in a liquid inlet. The latter opens to the right of each liquid circulation conduit of the hydraulic connector. The tightness at the orifice between the circulation ducts of the hydraulic connector and the distribution channels 29 and 30 of the
20 dispositif de connexion est assurée par un moyen d'étanchéité, par exemple un joint. L'orifice d'admission forme ainsi un plan qui reçoit le moyen d'étanchéité installé entre le dispositif de connexion 27 et le connecteur hydraulique 5. 20 connection device is provided by a sealing means, for example a seal. The inlet thus forms a plane which receives the sealing means installed between the connection device 27 and the hydraulic connector 5.
Les canaux de distribution 29 ou 30 s'étendent principalement selon une direction longitudinal 1 12, par exemple rectiligne. Cette direction est parallèle à la 25 direction longitudinale du balai 3.  The distribution channels 29 or 30 extend mainly in a longitudinal direction 1 12, for example rectilinear. This direction is parallel to the longitudinal direction of the blade 3.
Enfin, le dispositif de connexion 27 présente une première extrémité 104 qui supporte une casquette 35. Cette dernière ferme une partie avant de l'ensemble formé par l'extrémité 2 du bras, l'adaptateur 9, le connecteur hydraulique 5 et le dispositif de connexion 27. Cette casquette 35 joue un rôle d'écran pour protéger Finally, the connection device 27 has a first end 104 which supports a cap 35. The latter closes a front part of the assembly formed by the end 2 of the arm, the adapter 9, the hydraulic connector 5 and the device of FIG. connection 27. This cap 35 plays a role of screen to protect
30 ces composants tout en assurant une finition extérieur de bonne facture. 30 these components while ensuring an exterior finish of good quality.
La figure 3 illustre en détail un exemple de réalisation du connecteur hydraulique 5. Ce dernier est formé par un corps 1 3 qui présente une section globalement rectangulaire bordé latéralement par un premier flan 15 et un deuxième flan 16. FIG. 3 illustrates in detail an exemplary embodiment of the hydraulic connector 5. The latter is formed by a body 1 3 which has a section generally rectangular bordered laterally by a first blank 15 and a second blank 16.
Le connecteur 5 est qualifié d'hydraulique en ce sens qu'il conduit ou canalise un liquide. Pour ce faire, deux conduits de circulation d'un liquide 17 et 5 18 sont formés dans le corps 13. Les deux conduits 17 et 18 sont chacun terminé par un tube de raccordement qui forme une zone d'accostage des tuyaux 4. A l'extrémité opposée à ce tube de raccordement, chaque conduit est terminé par un orifice d'évacuation référencé 100 et 101 . Le conduit 17 ou 18 comprend donc une première partie rectiligne et une deuxième partie qui s'étend dans une î o direction sensiblement orthogonale à la direction rectiligne.  The connector 5 is qualified hydraulic in that it conducts or channels a liquid. To do this, two fluid circulation ducts 17 and 18 are formed in the body 13. The two ducts 17 and 18 are each terminated by a connection tube which forms a docking zone for the pipes 4. To opposite end to this connecting tube, each conduit is terminated by a discharge port referenced 100 and 101. The conduit 17 or 18 therefore comprises a first rectilinear part and a second part which extends in a direction which is substantially orthogonal to the rectilinear direction.
Le connecteur hydraulique est croisé par l'axe de rotation 23. En pratique, c'est le connecteur hydraulique 5 qui sert de base et autour duquel le bras et éventuellement l'adaptateur peuvent tournés. Pour ce faire, le connecteur hydraulique comprend un moyen de rotation qui peut prendre toute forme pour The hydraulic connector is crossed by the axis of rotation 23. In practice, it is the hydraulic connector 5 which serves as a base and around which the arm and possibly the adapter can be rotated. To do this, the hydraulic connector comprises a rotation means which can take any form for
15 autant qu'il autorise une rotation. 15 as much as it allows rotation.
Dans cet exemple de réalisation, ce moyen de rotation prend la forme d'un arbre 25 d'axe confondu avec l'axe de rotation 23. Cet arbre 25 forme un tourillon de section cylindrique qui débouche d'une face externe du premier et du deuxième flan 15 et 16. Quand l'adaptateur 9 est monté sur le connecteur In this embodiment, this means of rotation takes the form of a shaft 25 of axis coinciding with the axis of rotation 23. This shaft 25 forms a cylindrical section pin which opens out of an outer face of the first and the second blank 15 and 16. When the adapter 9 is mounted on the connector
20 hydraulique 5, les arbres 25 sont logés dans les trous 24a et 24b pratiqués dans chaque paroi latérale de l'adaptateur. 5, the shafts 25 are housed in the holes 24a and 24b formed in each side wall of the adapter.
L'invention couvre aussi le cas où le connecteur hydraulique 5 comprend un moyen de rotation qui prend la forme d'au moins un trou pratiqué dans le premier flan 15 et dans le deuxième flan 16, ces trous étant destinés à recevoir des arbres The invention also covers the case where the hydraulic connector 5 comprises a means of rotation which takes the form of at least one hole made in the first blank 15 and in the second blank 16, these holes being intended to receive shafts.
25 fabriqués dans l'adaptateur. 25 made in the adapter.
Le connecteur hydraulique 5 comprend aussi au moins une piste conductrice d'électricité qui chem ine à l' intérieur du corps 1 3 du connecteur. Dans cet exemple, le connecteur hydraulique comprend deux pistes distinctes 102 et 103 dont une zone est apparente au niveau d'une face du corps du connecteur The hydraulic connector 5 also comprises at least one electrically conductive track which runs inside the body 1 3 of the connector. In this example, the hydraulic connector comprises two separate tracks 102 and 103, an area of which is apparent at a face of the connector body
30 hydraulique. Il s'agit ici d'un point de contact électrique voué à coopérer avec un dispositif conducteur d'électricité intégré au dispositif de connexion. Ces pistes 102 et 103 sont raccordées au réseau électrique du véhicule au niveau d'une face arrière du corps 13 qui croise les tubes de raccordement des conduits 17 et 18.30 hydraulic. This is an electrical contact point dedicated to cooperate with an electrically conductive device integrated in the connection device. These tracks 102 and 103 are connected to the electrical network of the vehicle at a face rear of the body 13 which crosses the connecting tubes of the ducts 17 and 18.
La figure 4 montre en détail le dispositif de connexion 27 selon l'invention. Ce dernier comprend une embase 31 qui présente une forme générale rectangulaire comprenant une direction d'extension longitudinale et une direction 5 d'extension transversale. Cette embase 31 est bordée sur un premier côté par le premier canal de distribution de liquide 29. Un second côté opposé au premier côté par rapport à l'embase 31 reçoit un second canal de distribution de liquide 30. Ces canaux présentent chacun une section tubulaire qui s'étend de manière rectiligne selon la direction longitudinale du dispositif de connexion, et plus î o particulièrement de l'em base 31 . On notera que ces sections tubulaires dépassent de part et d'autre d'une première extrémité 1 04 et d'une deuxième extrémité 105 de l'embase 31 . Figure 4 shows in detail the connection device 27 according to the invention. The latter comprises a base 31 which has a generally rectangular shape comprising a direction of longitudinal extension and a direction 5 of transverse extension. This base 31 is bordered on a first side by the first liquid distribution channel 29. A second side opposite the first side relative to the base 31 receives a second liquid distribution channel 30. These channels each have a tubular section which extends rectilinearly in the longitudinal direction of the connecting device, and more particularly o em base 31. It will be noted that these tubular sections protrude on either side of a first end 104 and a second end 105 of the base 31.
L'embase 31 , les canaux de distribution 29 et 30 et la casquette 35 forment une pièce unitaire avantageusement moulée à partir d'un plastique.  The base 31, the distribution channels 29 and 30 and the cap 35 form a unitary piece advantageously molded from a plastic.

Chaque canal de distribution 29 ou 30 est relié à un orifice d'admission 107, respectivement 108, par un puits 1 14, respectivement 1 15. Ce puits établit la communication hydraulique entre l'orifice d'admission et le canal de distribution 15 concerné. Ce puits s'étend selon une direction concourante, c'est-à-dire qui croise la direction longitudinale 1 12. Les puits 1 14 ou 1 15 prennent la forme d'un cône évasé en direction de l'orifice d'admission.  Each distribution channel 29 or 30 is connected to an intake orifice 107, respectively 108, by a well 11, respectively 1 15. This well establishes the hydraulic communication between the inlet orifice and the distribution channel 15 concerned. . This well extends in a concurrent direction, that is to say, which crosses the longitudinal direction 1 12. The wells 1 14 or 1 15 take the form of a cone flared in the direction of the inlet port.
Cette figure 6 met en avant un exemple de réalisation d'un moyen de solidarisation 1 17 constitutif du dispositif de connexion 27 selon l'invention. La 20 fonction de ce moyen de solidarisation est de relier mécaniquement le dispositif de connexion au balai. Il s'agit ici de rendre solidaire le dispositif de connexion et le balai une fois que ces deux composants sont assemblés.  This FIG. 6 shows an exemplary embodiment of a securing means 1 17 constituting the connection device 27 according to the invention. The function of this securing means is to mechanically connect the connection device to the brush. It is a matter of making the connecting device and the broom integral once these two components are assembled.
Le moyen de solidarisation 1 1 7 prend ici la forme d'une rainure 1 18 pratiquée de chaque côté de l'embase 31 . Cette rainure 1 18 s'étend dans une 25 direction parallèle à la direction longitudinale 1 12 d'un canal de distribution 29 ou 30. On notera également que cette rainure 1 18 est pratiquée sous le canal de distribution qui borde l'embase 31 et dans le prolongement de ce dernier.  The securing means 1 1 7 here takes the form of a groove 1 18 made on each side of the base 31. This groove 1 18 extends in a direction parallel to the longitudinal direction 1 12 of a distribution channel 29 or 30. It will also be noted that this groove 1 18 is formed under the distribution channel which borders the base 31 and in the extension of the latter.
La rainure 1 18 forme ainsi un logement dans lequel une armature du balai est reçue.  The groove 1 18 thus forms a housing in which a frame of the blade is received.
30 La partie de l'embase 31 dans laquelle est formée la rainure 1 18 est reliée au canal de distribution concerné par des bras de renfort 1 19, ce qui permet de rigidifier le moyen de solidarisation 1 17.

Le tenon 52 déborde latéralement du corps 13 du connecteur hydraulique 5 et présente une section circulaire. Ce tenon 52 est prisonnier du clip 54 fabriqué dans le dispositif de connexion 27. Ce clip 54 prend la forme de deux jambes qui forme une fourche et dans laquelle le tenon est maintenu en place puisque les The post 52 protrudes laterally from the body 13 of the hydraulic connector 5 and has a circular section. This tenon 52 is trapped in the clip 54 produced in the connection device 27. This clip 54 takes the form of two legs which form a fork and in which the tenon is held in place since the
30 jambes de la fourche enserrent le tenon 52. L'extrémité libre de chaque jambe constituant la fourche comprend un bossage de retenu qui maintient en place le tenon 52 une fois installé dans le clip 54. Le crochet 51 est également maintenu dans la gorge 53 si bien qu'en cette position, l'étanchéité hydraulique du liquide lave vitre entre le connecteur hydraulique 5 et le dispositif de connexion 27 est parfaitement assurée tout comme un contact électrique exempt de vibration entre le dispositif conducteur 5 d'électricité constitutif du dispositif de connexion et le conducteur ou piste électrique noyé dans le plastique formant le connecteur hydraulique. 30 legs of the fork grip the post 52. The free end of each leg constituting the fork comprises a retaining boss which holds in place the tenon 52 once installed in the clip 54. The hook 51 is also held in the groove 53 so that in this position, the hydraulic sealing of the window washer fluid between the hydraulic connector 5 and the connection device 27 is perfectly ensured as a vibration-free electrical contact between the electrical conductive device constituting the connecting device and the conductor or electric track embedded in the plastic forming the hydraulic connector.
La figure 9 illustre une phase de déblocage du moyen de fixation 26. En effectuant une rotation du connecteur hydraulique 5 par rapport au dispositif de connexion 27 autour de l'axe transversal qui passe par les crochets 51 , on extrait î o le tenon 52 du clip 54.  FIG. 9 illustrates a phase of unlocking the fastening means 26. By rotating the hydraulic connector 5 with respect to the connection device 27 around the transverse axis which passes through the hooks 51, the stud 52 is extracted from clip 54.
