Le domaine de la présente invention est celui des équipements pour les 5 véhicules, et plus particulièrement celui des équipements pour l'essuyage des vitres d'un véhicule. La présente invention vise un système de connexion assurant une liaison mécanique entre un bras d'essuyage et un balai d'essuyage apte à essuyer une vitre arrière ou un pare-brise du véhicule, notamment. î o Les véhicules automobiles sont couramment équipés de système d'essuie- glace pour assurer un balayage et un lavage du pare-brise et éviter que la vision qu'a le conducteur de son environnement ne soit perturbée. Ces essuie-glaces sont classiquement entraînés par un bras effectuant un mouvement de va-et-vient angulaire et comportent des balais allongés, porteurs eux-mêmes de lamesThe field of the present invention is that of equipment for vehicles, and more particularly that of equipment for wiping windows of a vehicle. The present invention provides a connection system providing a mechanical connection between a wiper arm and a wiper blade adapted to wipe a rear window or a windshield of the vehicle, in particular. Motor vehicles are commonly equipped with a windshield wiper system to sweep and wash the windshield and to prevent the driver's vision from being disturbed. These windscreen wipers are conventionally driven by an angularly reciprocating arm and comprise elongate brushes, themselves carrying blades.
15 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 réal isés sous la forme, soit, dans une version classique, de palonniers articulés qui tiennent la lame racleuse en plusieurs endroits discrets, soit, dans une version plus récente dénommée "flat blade" (pourScrapers 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.

Dans cette seconde solution, le balai est rattaché au bras tournant de l'essuie-glace par un ensemble constitué d'un connecteur mécanique et d'un adaptateur.

In this second solution, the blade is attached to the rotating arm of the wiper by a set consisting of a mechanical connector and an adapter.

These two parts are connected to each other by a transverse axis which allows their relative rotation in a plane perpendicular to the windshield passing through the arm.
Il est connu de relier le connecteur et l'adaptateur en enfilant un axe 30 transversal au travers de ces deux pièces, après alignement de ces dernières. It is known to connect the connector and the adapter by threading a transverse axis through these two parts, after alignment thereof.
Une telle solution technique présente plusieurs inconvénients. En effet, la liaison pivot qui résulte de ce montage fait ainsi appel à trois pièces distinctes. L'axe transversal est une pièce métallique, qui représente un coût non négligeable. Par ail leurs, l'util isation de ces trois pièces génère des compl ications d'ordre logistique lors de l'assemblage de l'adaptateur sur le connecteur. Il convient donc de modifier la connexion pour supprimer l'axe transversal. Such a technical solution has several disadvantages. Indeed, the pivot connection that results from this assembly and uses three separate parts. The transverse axis is a metal part, which represents a significant cost. In addition, the use of these three parts generates order compliications. logistics when assembling the adapter to the connector. It is therefore necessary to modify the connection to remove the transverse axis.
Le document WO2005/039944A1 divulgue un dispositif de connexion entre 5 un connecteur et un adaptateur d'un système d'essuyage. Le connecteur est fabriqué à partir d'une feu ille métall ique pl iée, une telle feuille étant alors porteuse de l'axe transversal sur lequel l'adaptateur est encliqueté. Dans cette solution technique, l'axe transversal reste néanmoins une pièce supplémentaire qu'il faut disposer préalablement sur le connecteur, avant d'enfiler l'adaptateur, î o Le positionnement de l'axe transversal impose ainsi une étape spécifique lors de l'assemblage de la connexion. WO2005 / 039944A1 discloses a connection device between a connector and an adapter of a wiper system. The connector is made from a light metal plate ply, such a sheet then carrying the transverse axis on which the adapter is latched. In this technical solution, however, the transverse axis remains an additional piece that must be previously arranged on the connector, before threading the adapter, o The positioning of the transverse axis thus imposes a specific step when the assembly of the connection.
Le but de la présente invention est donc de résoudre les inconvénients décrits ci-dessus principalement en supprimant l'axe transversal distinct qui 15 assure la liaison pivot entre l'adaptateur et le connecteur. Selon l'invention, cet axe transversal est directement issu de l'adaptateur, et ne forme ainsi pas une pièce supplémentaire dont il faut assurer le montage et la gestion logistique. The object of the present invention is therefore to overcome the disadvantages described above mainly by eliminating the distinct transverse axis which provides the pivotal connection between the adapter and the connector. According to the invention, this transverse axis is directly derived from the adapter, and thus does not form an additional part which must be provided for assembly and logistics management.
L'invention a donc pour objet un système de connexion apte à assurer une 20 liaison mécanique entre un bras d'essuyage et un balai d'essuyage, comprenant un connecteur apte à être fixé d irectement sur au moins un d ispositif de rigidification du balai d'essuyage et un adaptateur apte à être relié au bras d'essuyage, le connecteur et l'adaptateur étant reliés par une liaison pivot, où l'adaptateur délimite un logement dans lequel s'insère un flanc du connecteur, 25 caractérisé en ce que la liaison pivot est réalisée par au moins une excroissance issue de l'adaptateur et logée dans au moins une cavité ménagée dans le flanc. The invention therefore relates to a connection system capable of providing a mechanical connection between a wiper arm and a wiper blade, comprising a connector capable of being fastened directly to at least one bending stiffening device. wiper arm and an adapter adapted to be connected to the wiper arm, the connector and the adapter being connected by a pivot connection, wherein the adapter defines a housing into which a flank of the connector is inserted, characterized in that that the pivot connection is made by at least one protrusion from the adapter and housed in at least one cavity in the sidewall.
Dans un tel cas, le connecteur est une pièce qui est apte à venir en prise sur au moins une vertèbre logée dans une lame ou un support de lame du balai 30 d'essuyage. In such a case, the connector is a part that is adapted to engage at least one vertebra housed in a blade or blade holder of the wiper blade 30.
Ce connecteur est par exemple rendu solidaire du balai d'essuyage sensiblement au centre de celui-ci, selon une direction d'extension longitudinale du balai d'essuyage. This connector is for example made integral with the wiper blade substantially in the center thereof, in a direction of longitudinal extension. wiper blade.
Le système de connexion selon l'invention est adapté pour assurer une l iaison mécan ique à l'égard d'un balai de technologie plate, c'est-à-dire qui 5 comporte un unique point de fixation centrale et un ou plusieurs dispositifs de rigidification. The connection system according to the invention is adapted to provide a mechanical connection to a flat technology broom, i.e. which has a single central attachment point and one or more devices. stiffening.
Selon un exemple de l'invention, l'excroissance débouche dans le logement. î o Le système de connexion selon l'invention peut comprendre un moyen facil itant une insertion de l'excroissance dans la cavité. Le système peut comporter plusieurs de ces moyens disposés sur le connecteur et/ou l'adaptateur. According to an example of the invention, the protuberance opens into the housing. The connection system according to the invention may comprise means facilitating insertion of the protuberance into the cavity. The system may comprise several of these means disposed on the connector and / or the adapter.
Selon un exemple de réalisation de ce moyen, celui-ci est formé par au 15 moins un premier chanfrein ménagé à une extrémité libre de l'excroissance. Un tel chanfrein facilite la déformation de l'adaptateur pendant une étape d'insertion de l'excroissance dans la cavité. According to an exemplary embodiment of this means, it is formed by at least a first chamfer formed at a free end of the protrusion. Such a chamfer facilitates the deformation of the adapter during a step of insertion of the protrusion in the cavity.
Selon un autre exemple alternatif ou complémentaire, le moyen facilitant 20 l'insertion est formé par une languette flexible issue de l'adaptateur et formant support de l'excroissance. Une telle languette flexible est agencée pour autoriser un déplacement réversible de l'excroissance pendant la phase d'assemblage de l'adaptateur sur le connecteur. According to another alternative or complementary example, the means facilitating the insertion is formed by a flexible tongue coming from the adapter and forming the support of the protuberance. Such a flexible tongue is arranged to allow a reversible displacement of the protrusion during the assembly phase of the adapter on the connector.
25 Selon encore un exemple alternatif ou complémentaire, le moyen facilitant l'insertion est formé par une rainure ménagée dans le flanc et au droit de laquelle la cavité se term ine . U ne tel le ra inu re assure également un gu idage de l'excroissance vers la cavité. According to yet another alternative or complementary example, the means facilitating the insertion is formed by a groove formed in the sidewall and at the right of which the cavity terminates. U n such the ra inu re also ensures a gu idage of the outgrowth to the cavity.
30 Selon un exemple de réalisation, le moyen facilitant l'insertion est formé par un deuxième chanfrein ménagé sur le flanc, et qui s'étend au moins entre une arête bordant ce flanc et la cavité. Il est également possible que le moyen facilitant l'insertion soit formé par la rainure ménagée dans le flanc et au droit de laquelle la cavité se termine, un fond de la rainure formant le deuxième chanfrein. According to an exemplary embodiment, the means facilitating the insertion is formed by a second chamfer formed on the sidewall, which extends at least between an edge bordering this sidewall and the cavity. It is also possible that the means facilitating insertion is formed by the groove formed in the sidewall and the right of which the cavity ends, a bottom of the groove forming the second chamfer.
5  5
Selon un exemple de l'invention, la rainure s'étend au moins partiellement selon une direction passant par deux extrémités longitudinales du flanc.  According to an example of the invention, the groove extends at least partially in a direction passing through two longitudinal ends of the sidewall.
Le système de connexion selon l'invention peut comprendre un moyen de î o centrage de l'excroissance vers la cavité. Le moyen facilitant l'insertion décrit ci- dessus peut former un tel moyen de centrage. Autrement dit, certaines formes du moyen facilitant l'insertion peuvent également réaliser la fonction de centrage de l'excroissance par rapport à la cavité. The connection system according to the invention may comprise means for centering the protuberance towards the cavity. The insertion facilitating means described above may form such a centering means. In other words, some forms of the means facilitating insertion can also perform the centering function of the protrusion relative to the cavity.
15 Selon un mode de réalisation, le moyen de centrage prend la forme d'au moins une tranche ménagée dans le flanc et qui s'étend entre une arête bordant le flanc et la cavité. Une telle tranche peut être formée par une tranche de la rainure décrite ci-dessus. According to one embodiment, the centering means takes the form of at least one slice formed in the sidewall and which extends between an edge bordering the sidewall and the cavity. Such a slice may be formed by a slice of the groove described above.
20 Le centrage de l'excroissance vis-à-vis de la cavité est amélioré lorsque la tranche est inclinée en direction d'une extrémité longitudinale du flanc, par rapport à un plan vertical tangent à la cavité. The centering of the protrusion vis-à-vis the cavity is improved when the wafer is inclined towards a longitudinal end of the sidewall, relative to a vertical plane tangent to the cavity.
La liaison pivot est réalisée par l'excroissance et la cavité qui présentent 25 une section circulaire. The pivot connection is made by the protrusion and the cavity which have a circular section.
On notera que le connecteur peut comprendre au moins un conduit dans lequel un liquide de lavage de la vitre est apte à circuler. It will be noted that the connector may comprise at least one duct in which a liquid for washing the window is able to circulate.
30 Selon un exemple de réalisation de l'invention, l'adaptateur peut comprendre deux excroissances reçues dans deux cavités ménagées dans le connecteur, les deux cavités étant séparées l'une de l'autre par une paroi . Une telle paroi, solidaire du flanc, forme un renfort qui permet d'augmenter la tenue mécanique du connecteur. According to an exemplary embodiment of the invention, the adapter may comprise two protrusions received in two cavities formed in the connector, the two cavities being separated from one another by a wall. Such a wall, integral with the sidewall, forms a reinforcement that increases the mechanical strength of the connector.
L'invention concerne aussi un ensemble d'essuyage comprenant un bras d'essuyage, un balai d'essuyage et un unique système de connexion comprenant l'une quelconque des caractéristiques présentées ci-dessus, un tel système de connexion assurant une l iaison pivot entre le bras d 'essuyage et le balai d'essuyage, ainsi que la fixation démontable entre le balai d'essuyage et le bras d'essuyage. The invention also relates to a wiper assembly comprising a wiper arm, a wiper blade and a single connection system comprising any of the features presented above, such a connection system providing a pivotal connection. between the wiper arm and the wiper blade, as well as the removable attachment between the wiper blade and the wiper arm.
Un tout premier avantage selon l'invention réside d'une manière générale dans la simplification de l'assemblage entre un adaptateur et son connecteur. Cet assemblage ne nécessite que deux pièces primaires, sans qu'il soit utile de recourir à l'emploi d'un axe transversal d istinct du connecteur. L'étape de positionnement de l'axe transversal peut ainsi être supprimée. A first advantage of the invention resides in a general manner in the simplification of the assembly between an adapter and its connector. This assembly requires only two primary parts, without it being necessary to resort to the use of a transverse axis of the connector. The step of positioning the transverse axis can thus be deleted.
Un autre avantage réside dans la possibilité de réduire le coût de la fonction liée à la connexion mécanique entre un bras d'essuyage et un balai d'essuyage, en supprimant l'axe transversal distinct et en supprimant l'étape d'assemblage liée à cet axe transversal. Another advantage lies in the possibility of reducing the cost of the function related to the mechanical connection between a wiper arm and a wiper blade, by eliminating the distinct transverse axis and by eliminating the assembly step related to this transverse axis.

Il faut noter que les figures exposent l'invention de manière détaillée pour mettre en œuvre l'invention, 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 to implement the invention, said figures can of course be used to better define the invention where appropriate.
Le système de connexion selon l'invention comprend un connecteur 1 illustré sur la figure 1 associé à un adaptateur 2 représenté sur la figure 2. Ces deux pièces sont définies dans un repère orthonormé OX-OY-OZ, où la direction OX représente un axe longitudinal, la direction OZ représente un axe vertical et la direction OY représente un axe transversal. The connection system according to the invention comprises a connector 1 illustrated in Figure 1 associated with an adapter 2 shown in Figure 2. These two parts are defined in an orthonormal coordinate system OX-OY-OZ, where the direction OX represents an axis longitudinal, the direction OZ represents a vertical axis and the direction OY represents a transverse axis.
Le connecteur 1 montré sur la figure 1 est agencé pour être rendu solidaire, par exemple par sertissage, d'un balai d'essuyage qui se déplace sur un pare- brise de véhicule. Un tel balai d'essuyage est entraîné en rotation par un bras d'essuyage. The connector 1 shown in Figure 1 is arranged to be secured, for example by crimping, a wiper blade which moves on a vehicle windshield. Such wiper blade is rotated by a wiper arm.
Le connecteur 1 assure une liaison mécanique dite complète avec le balai d'essuyage, en ce sens qu'il n'existe pas de degré de liberté. Le connecteur 1 peut également assurer une fonction de transport et de distribution d'un liquide de lavage du pare-brise. The connector 1 provides a so-called complete mechanical connection with the wiper, in that there is no degree of freedom. The connector 1 can also provide a function for transporting and dispensing a windshield washing liquid.
Le connecteur 1 comprend une embase 3 qui s'étend longitudinalement et transversalement. Cette embase 3 comprend une zone de solidarisation 5 sur le bal ai d 'essuyage, et pl us particul ièrement su r u ne vertèbre de ce balai d'essuyage. Cette zone de solidarisation 5 prend par exemple la forme d'une saignée ménagée dans l'embase 3, cette saignée étant bordée par deux crochets aptes à venir en prise sur le balai d'essuyage. L'embase reçoit également un conduit 6 qui s'étend de manière rectiligne selon l'axe longitudinal OX. Un tel conduit 6 est ménagé sur u n côté de l 'embase 3, cette dern ière donnant naissance à deux embouts 7 qui délimitent le conduit 6, et sur lesquels s'enfile un moyen de distribution du liquide de lavage constitutif du balai d'essuyage. The connector 1 comprises a base 3 which extends longitudinally and transversely. This base 3 comprises a securing zone 5 on the wiper blade, and pl us particul ely su ru vertebra of this wiper blade. This securing zone 5 takes for example the shape of a groove formed in the base 3, this groove being bordered by two hooks adapted to engage on the wiper blade. The base also receives a conduit 6 which extends rectilinearly along the longitudinal axis OX. Such a duct 6 is formed on one side of the base 3, the latter giving rise to two end pieces 7 which delimit the duct 6, and on which is threaded a means of dispensing the washing liquid constituting the wiper blade .
L'embase 3 est surmontée d'un flanc 4, par exemple, issu de cette embase 3. Ce flanc 4 présente une dimension transversale et une dimension longitudinale inférieures à celles de l'embase 3. Le flanc 4 est par exemple centré sur l'embase 3, selon l'axe transversal OY et l'axe longitudinal OX. The base 3 is surmounted by a flank 4, for example, from this base 3. This flank 4 has a transverse dimension and a longitudinal dimension smaller than those of the base 3. The flank 4 is for example centered on the base 3, along the transverse axis OY and the longitudinal axis OX.
Le flanc 4 reçoit un canal 8 de circulation par lequel le liquide de lavage peut arriver. Un tel canal 8 est ainsi délimité par le flanc 8 et par un embout 7 qui prend naissance sur le flanc 4, et sur lequel s'enfile un tube de transport du liquide de lavage du pare-brise. The flank 4 receives a circulation channel 8 through which the washing liquid can arrive. Such a channel 8 is thus delimited by the sidewall 8 and a tip 7 which originates on the sidewall 4, and on which a windshield washing liquid transport tube is inserted.
On notera que le flanc 4 peut présenter une pluralité de nervures 9 qui assurent un renforcement mécanique du flanc 4. It will be noted that the flank 4 may have a plurality of ribs 9 which provide a mechanical reinforcement of the flank 4.
Le connecteur 1 et l'adaptateur 2 sont reliés mécaniquement par une liaison pivot. En ce qui concerne le connecteur 1 , cette liaison pivot est mise en œuvre par une cavité 10 réalisée dans le flanc 4. Cette cavité 1 0 s'étend selon l'axe transversal OY et présente une section circulaire. En d'autres termes, la cavité 10 peut être un trou d'axe central 1 1 , ce dernier étant parallèle à l'axe transversal OY. Dans le plan OXZ, la cavité 10 présente une section circulaire. The connector 1 and the adapter 2 are mechanically connected by a pivot connection. As regards the connector 1, this pivot connection is implemented by a cavity 10 made in the sidewall 4. This cavity 1 0 extends along the transverse axis OY and has a circular section. In other words, the cavity 10 may be a central axis hole January 1, the latter being parallel to the transverse axis OY. In the plane OXZ, the cavity 10 has a circular section.
Le connecteur 1 décrit ci-dessus est avantageusement unitaire, c'est-à-dire constitué par une même matière synthétique. Ce connecteur peut ainsi être fabriqué au cours d'une unique opération de moulage, notamment par injection. La figure 2 montre l'adaptateur 2, ce dernier étant une pièce dont les formes sont adaptées aux formes réalisées à une extrémité du bras d'essuyage. Ainsi, le système de connexion selon l'invention peut être utilisé pour différents types de bras d'essuyage, les formes particulières de chaque bras étant reportées sur l'adaptateur 2, alors que le connecteur 1 reste identique quelque soit le type de bras d'essuyage utilisé. L'adaptateur 2 présente une section dans un plan OYZ en forme de U. Cette forme délimite un logement 12 dans lequel est inséré le flanc 4 du connecteur 1 . L'adaptateur 2 comprend donc une base 1 3 à partir de laquelle s'étend un premier côté 14 et un deuxième côté 15. Le logement 12 est ainsi bordé par la base 13, par le premier côté 14 et par le deuxième côté 15. The connector 1 described above is advantageously unitary, that is to say constituted by the same synthetic material. This connector can thus be manufactured during a single molding operation, in particular by injection. Figure 2 shows the adapter 2, the latter being a part whose shapes are adapted to the shapes made at one end of the wiper arm. Thus, the connection system according to the invention can be used for different types of wiper arm, the particular shapes of each arm being reported on the adapter 2, while the connector 1 remains the same regardless of the type of wiper arm used. The adapter 2 has a section in a U-shaped plane OYZ. This shape delimits a housing 12 in which the flank 4 of the connector 1 is inserted. The adapter 2 therefore comprises a base 1 3 from which extends a first side 14 and a second side 15. The housing 12 is thus bordered by the base 13, the first side 14 and the second side 15.
En ce qui concerne l'adaptateur 2, la liaison pivot est assurée par au moins une excroissance 1 6 qui vient se loger dans la cavité 1 0 ménagée dans le connecteur 1 . L'excroissance 16 forme ainsi une pièce mâle qui entre dans une forme femelle, cette dernière étant la cavité 1 0. On notera également que l'excroissance 16 peut déboucher ou dépasser dans le logement 12. Dans le plan OXZ, l'excroissance 16 présente une section circulaire. As regards the adapter 2, the pivot connection is provided by at least one protrusion 16 which is housed in the cavity 10 formed in the connector 1. The protrusion 16 thus forms a male part which enters a female form, the latter being the cavity 1 0. It will also be noted that the protuberance 16 may open or protrude into the housing 12. In the plane OXZ, the protrusion 16 has a circular section.
Selon l'exemple de réalisation, l'adaptateur 2 comprend deux excroissances 16 (une seule d'entre elles étant visible sur la figure 2) qui se font faces l'une à l'autre, par exemple. Ces deux excroissances forment chacune un toron circulaire 22 coaxial sur un axe de toron 1 7. Une fois l'adaptateur 2 assemblé sur le connecteur 1 , l'axe de toron 17 est confondu avec l'axe central 1 1 de la ou des cavités 10. Un bras de verrouillage 18 prend naissance sur la base 13 de l'adaptateur 2.According to the exemplary embodiment, the adapter 2 comprises two protuberances 16 (only one of them being visible in FIG. 2) which face each other, for example. These two protuberances each form a circular strand 22 coaxial on a strand axis 1 7. Once the adapter 2 assembled on the connector 1, the strand axis 17 coincides with the central axis 1 1 of the cavity or cavities 10. A locking arm 18 originates on the base 13 of the adapter 2.
Un tel bras de verrouillage 1 8 assure le blocage selon l'axe longitudinal OX de l'adaptateur 2 vis-à-vis du bras d'essuyage, un tel bras de verrouillage étant terminé par un plot 19 qui coopère avec un trou ménagé à l'extrémité du bras d'essuyage. Such a locking arm 1 8 ensures the locking along the longitudinal axis OX of the adapter 2 vis-à-vis the wiper arm, such a locking arm being terminated by a stud 19 which cooperates with a hole in the end of the wiper arm.
A l'autre extrémité longitudinale de l'adaptateur 2, on trouve un capot 20 dont la fonction est de fermer le logement 12 pour cacher la liaison mécanique entre le connecteur 1 et l'adaptateur 2. At the other longitudinal end of the adapter 2, there is a cover 20 whose function is to close the housing 12 to hide the mechanical connection between connector 1 and adapter 2.
A une extrémité libre du premier côté 14 et du deuxième côté 15, on trouve un bord 21 dont la fonction est d'assurer une butée selon l'axe vertical OZ à 5 encontre de l'extrémité du bras d'essuyage. At one free end of the first side 14 and the second side 15, there is an edge 21 whose function is to provide a stop along the vertical axis OZ against the end of the wiper arm.
Selon un exemple de l'invention, le système de connexion comprend un moyen 23 facilitant une insertion de l'excroissance 16 de l'adaptateur 2 dans la cavité 10 du connecteur 1 . Un tel moyen 23 peut être réalisé soit uniquement sur î o le connecteur 1 , soit uniquement sur l'adaptateur 2, soit sur ce connecteur 1 et sur cet adaptateur 2. According to an example of the invention, the connection system comprises a means 23 facilitating insertion of the protuberance 16 of the adapter 2 into the cavity 10 of the connector 1. Such a means 23 can be made either only on the connector 1, or only on the adapter 2, or on this connector 1 and on this adapter 2.
Selon un exemple de réalisation de ce moyen 23, il est ménagé un premier chanfrein 24 à une extrémité libre de l'excroissance 16. De manière plus précise, 15 un tel premier chanfrein 24 s'étend entre une face d'extrémité du toron circulaire 22 et une face périphérique de celui-ci. Ce premier chanfrein 24 est réalisé sur le toron, du côté opposé à la base 13 par rapport à l'axe de toron 17. According to an exemplary embodiment of this means 23, there is provided a first chamfer 24 at a free end of the protrusion 16. More specifically, such a first chamfer 24 extends between an end face of the circular strand 22 and a peripheral face thereof. This first chamfer 24 is formed on the strand, on the opposite side to the base 13 with respect to the strand axis 17.
La figure 2 montre un autre exemple de réalisation d'un moyen 23 facilitant 20 une insertion de l'excroissance 1 6 de l'adaptateur 2 dans la cavité 1 0 du connecteur 1 . Ce moyen 23 est ici formé par une languette flexible 25 issue de l'adaptateur 2 et formant support de l'excroissance 16. La languette flexible 25 est agencée de manière à autoriser un déplacement réversible de celle-ci selon l'axe transversal OY. Cette languette flexible 25 prend ainsi naissance sur la base 13 25 et s'étend parallèlement au premier côté 14 en ce qui concerne une première excroissance, ou au deuxième côté 1 5 en ce q u i concerne u ne deuxième excroissance 16. Cette languette flexible n'est pas reliée au côté concerné de l'adaptateur 2, une fente 26 entourant cette dernière. FIG. 2 shows another exemplary embodiment of a means 23 facilitating an insertion of the protrusion 166 of the adapter 2 into the cavity 1 0 of the connector 1. This means 23 is here formed by a flexible tongue 25 coming from the adapter 2 and forming a support for the protuberance 16. The flexible tongue 25 is arranged to allow a reversible displacement thereof along the transverse axis OY. This flexible tongue 25 thus originates on the base 13 25 and extends parallel to the first side 14 with respect to a first protrusion, or the second side 1 5 with respect to a second upright 16. This flexible tongue n ' is not connected to the relevant side of the adapter 2, a slot 26 surrounding the latter.
30 Le premier côté 14 et/ou le deuxième côté 15 comprend un dégagement 27 qui permet de libérer un espace entre la languette flexible 25 et le côté concerné, de manière à autoriser son mouvement réversible. Cette languette flexible 25 peut délimiter le logement 12. Elle porte l'excroissance 16, cette dernière étant issue de la languette flexible 25. The first side 14 and / or the second side 15 comprises a recess 27 which allows to release a space between the flexible tongue 25 and the concerned side, so as to allow its reversible movement. This flexible tongue 25 may delimit the housing 12. It carries the protuberance 16, the latter coming from the flexible tongue 25.
5 Selon l'exemple de la figure 2, l'adaptateur 2 comprend une première languette flexible 25 imméd iatement adjacente au prem ier côté 1 4 et une deuxième languette flexible 28 immédiatement adjacente au deuxième côté 15, et réalisée de manière identique à la première languette flexible 25. î o L'adaptateur 2 décrit ci-dessus est avantageusement unitaire, c'est-à-dire constitué par une même matière plastique. Cet adaptateur peut ainsi être fabriqué par une unique opération de moulage, notamment par injection. In the example of Figure 2, the adapter 2 comprises a first flexible tongue 25 immediately adjacent to the first side 14 and a second flexible tongue 28 immediately adjacent to the second side 15, and made identically to the first one. The adapter 2 described above is advantageously unitary, that is to say constituted by the same plastic material. This adapter can thus be manufactured by a single molding operation, in particular by injection.
La figure 3 est une vue partielle du connecteur 1 , montrant un mode de 15 réalisation d u moyen 23 facil itant u ne insertion de l 'excroissance 1 6 de l'adaptateur 2 dans la cavité 10 du connecteur 1 . Selon ce mode de réalisation, ce moyen 23 est aménagé sur le flanc 4 du connecteur 1 . Il s'agit ici d'une rainure 29 ménagée dans une face latérale 30 délimitant le flanc 4, et au droit de laquelle la cavité 10 se termine. On comprend ici que la rainure 29 et la cavité 10 sont en 20 intersection l'une avec l'autre, la rainure 29 s'étendant ainsi depuis une arête 34 du flanc 4 jusqu'au trou formant la cavité 10. FIG. 3 is a partial view of the connector 1, showing an embodiment of the means 23 facilitating the insertion of the protrusion 166 of the adapter 2 into the cavity 10 of the connector 1. According to this embodiment, this means 23 is arranged on the flank 4 of the connector 1. This is a groove 29 formed in a side face 30 defining the sidewall 4, and the right of which the cavity 10 ends. It is understood here that the groove 29 and the cavity 10 are in intersection with each other, the groove 29 thus extending from an edge 34 of the sidewall 4 to the hole forming the cavity 10.
Au droit de la rainure 29, le flanc 4 présente une épaisseur 31 inférieure à une épaisseur 32 d'une portion du flanc 4 bordant ladite rainure 29. Ces 25 épaisseurs sont mesurées selon une direction parallèle à l'axe de la liaison pivot, c'est-à-dire parallèlement à l'axe central 1 1 ou à l'axe transversal OY. Ainsi formée, cette rainure 29 est délimitée par un fond 35 et par deux tranches 36 qui relient le fond 35 à la face latérale 30. At the right of the groove 29, the flank 4 has a thickness 31 less than a thickness 32 of a portion of the flank 4 bordering said groove 29. These thicknesses are measured in a direction parallel to the axis of the pivot connection, c that is parallel to the central axis 1 1 or the transverse axis OY. Thus formed, this groove 29 is delimited by a bottom 35 and two slices 36 which connect the bottom 35 to the lateral face 30.
30 Bien entendu, le flanc 4 peut être pourvu de deux rainures identiques ménagées sur chacune des faces latérales 30 et 33 délimitant le flanc 4. Le système de connexion selon l'invention peut être pourvu d'un moyen de centrage 37 de l'excroissance 16 vers la cavité 10. La fonction de ce moyen de centrage 37 est de conduire, c'est-à-dire diriger, l'excroissance 16 de manière à la rendre coaxiale avec la cavité 10. Of course, the flank 4 may be provided with two identical grooves formed on each of the lateral faces 30 and 33 delimiting the flank 4. The connection system according to the invention can be provided with a means 37 for centering the protuberance 16 towards the cavity 10. The function of this centering means 37 is to drive, that is to say to direct, the protrusion 16 so as to make it coaxial with the cavity 10.
5  5
Selon un exemple de réalisation illustré à la figure 4, ce moyen de centrage 37 prend la forme d'une inclinaison de la ou des tranches 36 bordant la rainure 29. Cette tranche 36 s'étend ainsi depuis l'arête 34 bordant la face latérale 30 du fl anc 4 j usq u 'à l a cavité 1 0, en particu l ier en tangentant cette dernière, î o L'incl inaison est opérée de tel le sorte que la distance qu i sépare un bord angulaire situé entre la tranche 36 et l'arête 34, et l'extrémité longitudinale du flanc 4 soit inférieure à une distance qui sépare un point de tangence de la tranche 36 sur la cavité 1 0 et la même extrémité longitudinale, cette dernière étant celle où débouche l'embout 7.  According to an exemplary embodiment illustrated in FIG. 4, this centering means 37 takes the form of an inclination of the slice (s) 36 bordering the groove 29. This slice 36 thus extends from the edge 34 bordering the lateral face. The inclination is made such that the distance between an angular edge situated between the edge 36 and the edge 34, and the longitudinal end of the flank 4 is less than a distance between a tangent point of the edge 36 on the cavity 1 0 and the same longitudinal end, the latter being that where the tip 7 opens .
15  15
L'inclinaison de la tranche 36 est réalisée de manière à former un angle 38 entre la tranche 36 et un plan vertical tangent à la cavité 10, c'est-à-dire un plan OYZ.  The inclination of the wafer 36 is formed so as to form an angle 38 between the wafer 36 and a vertical plane tangent to the cavity 10, that is to say a plane OYZ.
20 Lorsque le connecteur 1 est pourvu de deux flancs 36 tels que détaillés ci- dessus, il est formé un cône de guidage de l'excroissance 16 vers la cavité 10. When the connector 1 is provided with two sidewalls 36 as detailed above, a cone is formed for guiding the protuberance 16 towards the cavity 10.
La figure 5 montre à nouveau un exemple de réalisation d'un moyen 23 facilitant l'insertion de l'excroissance 16 dans la cavité 10. Cette figure est une 25 coupe selon le plan OYZ du connecteur 1 et passant par l'axe central 1 1 . FIG. 5 again shows an exemplary embodiment of a means 23 facilitating the insertion of the protrusion 16 into the cavity 10. This figure is a section along the plane OYZ of the connector 1 and passing through the central axis 1 1.
Selon cet exemple, ce moyen 23 est réalisé par une inclinaison du fond 35 délimitant la rainure 29, formant ainsi un deuxième chanfrein. Il existe ainsi un angle 39 entre un plan passant par le fond 35 et un plan vertical OXY. Un tel 30 angle 39 se traduit par une augmentation progressive de l'épaisseur 31 du flanc 4 au fur et à mesure que l'excroissance 16 est approchée de la cavité 10, pendant la phase d'assemblage de l'adaptateur 2 sur le connecteur 1 . L'exemple de réalisation détaillé ci-dessus mentionne que le fond 35 de la rainure est incliné. L'invention couvre également le cas où le flanc 4 est dépourvu de rainure 29. Dans un tel cas, le deuxième chanfrein peut être réalisé tout le 5 long du flanc 4, c'est-à-dire d'une extrémité longitudinale à l'autre de ce flanc 4. According to this example, this means 23 is formed by an inclination of the bottom 35 delimiting the groove 29, thus forming a second chamfer. There is thus an angle 39 between a plane passing through the bottom 35 and a vertical plane OXY. Such an angle 39 results in a gradual increase in the thickness 31 of the sidewall 4 as the protuberance 16 is approached to the cavity 10 during the assembly phase of the adapter 2 on the connector 1. The embodiment detailed above mentions that the bottom 35 of the groove is inclined. The invention also covers the case where the flank 4 is devoid of groove 29. In such a case, the second chamfer can be made all along the flank 4, that is to say from one longitudinal end to the other. other of this flank 4.
La figure 6 montre une variante de réal isation du connecteur 1 . Ce connecteur 1 est identique au connecteur décrit en référence à la figure 1 à l'exception de ce qui suit, la description en rapport avec cette figure étant bien î o entendu transposable au connecteur 1 illustré sur la figure 6. FIG. 6 shows a variant of realisation of the connector 1. This connector 1 is identical to the connector described with reference to FIG. 1 with the exception of the following, the description with respect to this figure being of course transposable to the connector 1 illustrated in FIG.
Dans le cas du connecteur de la figure 1 , l'assemblage de l'adaptateur 2 sur le connecteur 1 est réalisé uniquement par une translation selon l'axe vertical OZ. In the case of the connector of Figure 1, the assembly of the adapter 2 on the connector 1 is made only by a translation along the vertical axis OZ.
15 En ce qui concerne le connecteur 1 de la figure 6, l 'assemblage de l'adaptateur de la figure 2 est réalisé par une étape de translation selon l'axe OZ su ivie d'une étape de translation selon l'axe OX. Pour ce faire, le flanc 4 comprend une rainure 29 dont une entrée 42 est décalée longitudinalement par rapport à l'axe central 1 1 de la cavité 10. Le flanc 4 comprend ainsi une portionWith regard to the connector 1 of FIG. 6, the assembly of the adapter of FIG. 2 is carried out by a step of translation along the axis OZ of a translational step along the axis OX. To do this, the flank 4 comprises a groove 29, an inlet 42 is offset longitudinally relative to the central axis 1 1 of the cavity 10. The flank 4 thus comprises a portion
20 41 qui se poursuit au dessus de la cavité 10. La rainure 29 présente un profil en L, où la rainure s'étend au moins en partie selon une direction passant par les deux extrémités longitudinales du flanc 4. The groove 29 has an L-shaped profile, where the groove extends at least partly in a direction passing through the two longitudinal ends of the sidewall 4.
Dans un tel cas, l'excroissance 16 de l'adaptateur 2 est présentée face à 25 l'entrée 42, translaté selon l'axe OZ, puis translaté selon l'axe OX jusqu'à ce que l'excroissance 16 de loge dans la cavité 10. In such a case, the protuberance 16 of the adapter 2 is presented facing the inlet 42, translated along the axis OZ, and then translated along the axis OX until the box protrusion 16 in the cavity 10.
Selon une variante de réalisation applicable à l'un quelconque des modes décrits ci-dessus, le système de connexion peut comprendre deux excroissances, 30 par exemple coaxiales. De manière complémentaire, le connecteur comprend deux cavités, notamment coaxiales. Ces deux cavités peuvent être formées par un même trou traversant de part en part le flanc. Il est également possible que le flanc comprenne une paroi qui sépare les deux cavités, formant ainsi deux trous borgnes dans le flanc. According to an alternative embodiment applicable to any of the modes described above, the connection system may comprise two excrescences, for example coaxial. In a complementary manner, the connector comprises two cavities, in particular coaxial cavities. These two cavities can be formed by a single through hole from side to side the sidewall. It is also possible that the sidewall comprises a wall separating the two cavities, thus forming two blind holes in the sidewall.
Le système de connexion évoqué dans la description des figures 1 à 6 est 5 particulièrement adapté pour relier mécaniquement un bras d'essuyage à un balai d'essuyage, la liaison pivot permettant de mettre en œuvre une rotation du balai d'essuyage par rapport au bras d'essuyage. Ces composants forment ainsi un ensemble d'essuyage pour véhicule automobile. î o Le balai d'essuyage de cet ensemble d'essuyage comprend une lame d'essuyage, autrement appelée raclette, qui s'étend longitudinalement le long du balai d'essuyage. Cette dernière est un composant souple du balai d'essuyage en appui contre la face extérieure du pare-brise à essuyer. The connection system mentioned in the description of FIGS. 1 to 6 is particularly suitable for mechanically connecting a wiper arm to a wiper blade, the pivot connection enabling the wiper blade to be rotated relative to the wiper blade. wiper arm. These components thus form a wiper assembly for a motor vehicle. The wiper blade of this wiper assembly includes a wiper blade, otherwise referred to as a squeegee, which extends longitudinally along the wiper blade. The latter is a flexible component of the wiper blade resting against the outer face of the windshield to be wiped.
15 Le balai d'essuyage comprend encore au moins un élément dans lequel est ménagé au moins un conduit apte à canaliser le liquide de lavage du pare-brise. Selon un exemple de réalisation, l'élément est un déflecteur d'air qui coiffe une partie supérieure du balai d'essuyage, un tel déflecteur d'air étant notamment m u n i d 'u ne au be déflectrice agencée pou r util iser l 'effet dynam iq ue d uThe wiper blade further comprises at least one element in which is provided at least one duct capable of channeling the washing liquid of the windshield. According to an exemplary embodiment, the element is an air deflector which cap an upper portion of the wiper blade, such air deflector being in particular munid 'u ne bebe deflector arranged to use the dynam e effect of the
20 déplacement du véhicule pour augmenter la force d'appui du balai d'essuyage sur le pare-brise. 20 movement of the vehicle to increase the support force of the wiper blade on the windshield.
Le balai d'essuyage est pourvu de deux éléments distincts enfilés sur le balai d'essuyage de part et d'autre du système de connexion selon l'invention. A 25 titre d'exemple de réal isation , les deux éléments présentent une structure identique à celle décrite ci-dessus, c'est-à-dire délimitant au moins un conduit et présentant au moins une aube déflectrice. The wiper blade is provided with two separate elements threaded onto the wiper blade on either side of the connection system according to the invention. As an example of real isation, the two elements have a structure identical to that described above, that is to say, defining at least one duct and having at least one deflector blade.
Le balai d'essuyage comprend également au moins un dispositif de 30 rigidification de la lame d'essuyage. Un tel dispositif de rigidification peut être formé par une ou deux vertèbres, ces dernières prenant la forme d'une lame métallique qui précontraint le balai d'essuyage de manière à suivre une courbe quand celui-ci n'est pas appliqué contre le pare-brise. La ou les deux vertèbres sont rendues solidaires de la lame d'essuyage constitutive du balai d'essuyage, par exemple au moyen du connecteur et/ou à l'aide d'un embout d'extrémité enfilé sur les extrémités longitudinales du balai d'essuyage. La lame d'essuyage peut 5 être pourvu de deux fentes ouvertes le long du balai d'essuyage et disposées latéralement sur celle-ci, ces deux fentes recevant chacune une vertèbre de rigidification. Alternativement, le balai peut comprendre un support dans lequel est ménagée une rainure qu i reçoit un talon de la lame d'essuyage et un logement long itud inale dans lequel est installée u ne u n iq ue vertèbre de î o rigidification. The wiper blade also includes at least one stiffening device for the wiper blade. Such a stiffening device may be formed by one or two vertebrae, the latter taking the form of a metal blade which prestresses the wiper blade so as to follow a curve when it is not applied against the windshield.
