Description

BALAI D'ESSUIE-GLACE DE VEHICULE, NOTAMMENT AUTOMOBILE, A DISTRIBUTION DE LIQUIDE DE NETTOYAGE AMELIOREE, ET ESSUIE- GLACE ET VEHICULE AUTOMOBILE ASSOCIE.VEHICLE WIPER BLADE, ESPECIALLY AUTOMOTIVE, WITH IMPROVED CLEANING FLUID DISTRIBUTION, AND ICE WIPER AND ASSOCIATED MOTOR VEHICLE.

L'invention concerne principalement un balai d'essuie-glace de véhicule, notamment automobile, permettant d'améliorer la distribution du liquide de nettoyage sur la surface à nettoyer lors de l'activation du dit balai pendant l'avancement du véhicule.The invention relates primarily to a vehicle wiper blade, in particular automobile, to improve the distribution of the cleaning liquid on the surface to be cleaned during the activation of said broom during the advance of the vehicle.

L'invention concerne également un essuie-glace comportant un tel balai. De façon connue, le nettoyage du pare-brise ou de la lunette arrière d'un véhicule automobile s'effectue par projection du liquide de lavage sur la surface à nettoyer depuis un gicleur situé sur le capot du véhicule ou en périphérie de la lunette arrière.The invention also relates to a wiper comprising such a broom. In known manner, the cleaning of the windshield or the rear window of a motor vehicle is effected by spraying the washing liquid on the surface to be cleaned from a nozzle located on the hood of the vehicle or the periphery of the rear window .

De tels gicleurs entraînent une projection de liquide de lavage inégalement répartie sur la surface de la vitre à nettoyer, ce dont il résulte une qualité de nettoyage insatisfaisante. La publication FR2603850 décrit un système de projection de liquide de nettoyage intégré au balai d'essuie-glace. A cet effet, un déflecteur est monté sur la partie supérieure du balai en s'étendant jusqu'à proximité de la surface à nettoyer. Le déflecteur intègre une rampe d'alimentation en liquide de nettoyage ainsi que des orifices d'aspersion. La structure du déflecteur permet de former une zone d'air calme au niveau de la projection du jet de liquide et ce, même lorsque le véhicule circule à grande vitesse.Such nozzles cause a projection of washing liquid unevenly distributed on the surface of the glass to be cleaned, which results in unsatisfactory cleaning quality. The publication FR2603850 describes a cleaning fluid projection system integrated in the windscreen wiper blade. For this purpose, a deflector is mounted on the upper part of the blade extending to near the surface to be cleaned. The baffle incorporates a cleaning liquid supply ramp and spray holes. The structure of the deflector makes it possible to form a zone of calm air at the level of the projection of the jet of liquid, even when the vehicle is traveling at high speed.

Ce système présente l'inconvénient de mettre en jeu une pièce supplémentaire, à savoir le déflecteur monté sur le balai d'essuie glace et un système complexe de projection du liquide de nettoyage. Par ailleurs, la rigidité du déflecteur empêche le balai de présenter une forme galbée assurant le contact entre la lame d'essuyage et la surface à nettoyer, ce qui nuit à la qualité du nettoyage de la dite surface. Dans ce contexte, la présente invention vise un balai d'essuie-glace permettant de pallier les inconvénients précités. A cet effet, le balai d'essuie-glace de véhicule, notamment automobile, de l'invention comporte au moins un corps longitudinal solidaire le long de sa partie inférieure à une lame d'essuyage selon un axe transversal du balai, et au moins une vertèbre principale qui s'étend le long du corps longitudinal en présentant au moins une partie longitudinale située dans l'épaisseur du corps du dit balai, et est essentiellement caractérisé en ce qu'il comporte des moyens de projection d'un liquide de nettoyage à proximité de la lame d'essuyage, et en ce que l'un des bords longitudinaux de la vertèbre principale situé du coté du liquide de nettoyage projeté, s'étend à proximité de la surface à essuyer en formant une zone coudée de protection du liquide projeté des écoulements d'air issus de l'avancement du véhicule.This system has the disadvantage of putting into play an additional piece, namely the deflector mounted on the wiper blade and a complex system of projection of the cleaning liquid. Furthermore, the rigidity of the baffle prevents the blade from having a curved shape ensuring contact between the wiper blade and the surface to be cleaned, which affects the quality of cleaning of said surface. In this context, the present invention aims a wiper blade to overcome the aforementioned drawbacks. For this purpose, the wiper blade of a vehicle, in particular an automobile, of the invention comprises at least one longitudinal body secured along its lower part to a wiping blade along a transverse axis of the blade, and at least a main vertebra which extends along the longitudinal body having at least one longitudinal portion located in the thickness of the body of said brush, and is essentially characterized in that it comprises means for spraying a cleaning liquid close to the wiper blade, and in that one of the longitudinal edges of the main vertebra located on the side of the projected cleaning liquid, extends close to the surface to be wiped, forming a bent protection zone of the liquid projected air flows from the advance of the vehicle.

Le balai d'essuie-glace de l'invention peut également comporter les caractéristiques optionnelles suivantes considérées isolément ou selon toutes les combinaisons techniques possibles : - le bord longitudinal de la vertèbre principale qui est situé à proximité de la surface à nettoyer comporte au moins une zone discontinue. - la zone discontinue est une rainure qui s'étend transversalement le long de la zone coudée de protection du liquide projeté jusqu'au bord longitudinal de la vertèbre principale qui est situé à proximité de la surface à nettoyer. - le bord longitudinal de la vertèbre principale qui est situé à proximité de la surface à nettoyer comporte une pluralité de zones discontinues régulièrement réparties le long du dit bord longitudinal. - le bord longitudinal opposé de la vertèbre principale est emmanché dans un logement borgne longitudinal réalisé dans l'épaisseur du corps du balai, et la partie de la vertèbre principale située entre le bord longitudinal opposé et la zone coudée est sensiblement perpendiculaire à l'axe transversal du balai. - le balai d'essuie-glace comporte une seconde vertèbre située du coté opposé au liquide de nettoyage projeté et s'étendant sensiblement perpendiculairement à l'axe transversal du balai depuis un bord longitudinal emmanché dans un logement borgne longitudinal réalisé dans l'épaisseur de corps du balai jusqu'au bord longitudinal libre opposé situé à distance de la surface à nettoyer. - les bords longitudinaux respectifs de la vertèbre principale et de la seconde vertèbre qui sont emmanchés dans les logements borgne respectifs se font face dans un même plan sensiblement perpendiculaire à l'axe transversal du balai. - le corps longitudinal et la lame d'essuyage du dit balai sont réalisés en une seule pièce. L'invention porte en outre sur un essuie-glace de véhicule, notamment automobile, comportant un balai d'essuie-glace tel que précédemment défini.The wiper blade of the invention may also include the following optional features considered in isolation or in any possible technical combination: the longitudinal edge of the main vertebra which is located near the surface to be cleaned comprises at least one discontinuous zone. the discontinuous zone is a groove that extends transversely along the bent zone for protecting the liquid sprayed up to the longitudinal edge of the main vertebra which is located near the surface to be cleaned. - The longitudinal edge of the main vertebra which is located near the surface to be cleaned comprises a plurality of discontinuous areas evenly distributed along said longitudinal edge. - The opposite longitudinal edge of the main vertebra is fitted in a longitudinal blind housing made in the thickness of the body of the blade, and the portion of the main vertebra located between the opposite longitudinal edge and the bent zone is substantially perpendicular to the axis. transverse broom. the wiper blade comprises a second vertebra located on the opposite side to the projected cleaning liquid and extending substantially perpendicularly to the transverse axis of the wiper from a longitudinal edge fitted into a longitudinal blind housing made in the thickness of body of the broom to the opposite free longitudinal edge located at a distance from the surface to be cleaned. the respective longitudinal edges of the main vertebra and the second vertebra which are fitted into the respective blind housings face each other in the same plane substantially perpendicular to the transverse axis of the blade. - The longitudinal body and the wiper blade of said broom are made in one piece. The invention furthermore relates to a vehicle windscreen wiper, in particular a motor vehicle, comprising a windscreen wiper blade as previously defined.

Enfin, l'invention concerne un véhicule automobile comprenant au moins un tel essuie-glace. D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est donnée ci-dessous, à titre indicatif et nullement limitatif, en référence aux figures annexées parmi lesquelles : - la figure 1 est une représentation schématique en perspective de l'extrémité d'un balai d'essuie-glace intégrant un système de projection de liquide de nettoyage, - la figure 2 est une représentation schématique en coupe du balai d'essuie-glace de la figure 1 selon la ligne II-II illustrant les écoulements d'air issus de l'avancement du véhicule, - la figure 3 est une représentation schématique en perspective d'un essuie-glace de l'invention, et - la figure 4 est une représentation schématique en perspective du balai d'essuie-glace de l'invention prise au niveau d'une coupe selon la ligne IV-IV de la figure 3. En référence à la figure 1, le balai d'essuie-glace de l'invention intègre des moyens de projection du liquide de nettoyage à proximité de la lame d'essuyage. Pour ce faire, le balai d'essuie-glace 1 présente un corps longitudinal 2 solidaire le long de sa partie inférieure à une lame d'essuyage galbée 3 permettant de s'adapter au galbe de la surface à nettoyer. Le corps longitudinal 2 et la lame d'essuyage 3 s'étendent selon un axe transversal YY' du balai d'essuie-glace 1 (figure 2). Un embout de distribution du liquide 4 est fixé à l'une des extrémités du balai 1 et comporte d'une part une tubulure d'arrivée du liquide de nettoyage 5 connectée à des moyens d'alimentation en liquide de nettoyage non représentés, et d'autre part un gicleur 6 apte à projeter le liquide de nettoyage 7 à proximité et le long de la lame d'essuyage 3. Comme visible sur la figure 2, le liquide de nettoyage 7 est projeté parallèlement à la lame d'essuyage 3 à proximité à la fois de la dite lame 3 et de la surface à nettoyer 8. Comme visible sur la figure 2 et de façon connue, un balai d'essuie-glace comporte une vertèbre métallique 10 emmanchée dans un logement borgne longitudinal 11 réalisé dans l'épaisseur du corps 2 du balai d'essuie-glace 1. La vertèbre métallique 10 ne s'oppose pas au galbe de la lame d'essuyage 3 précédemment évoqué. En référence à la figure 2, l'avancement du véhicule entraîne la formation d'écoulements d'air 9 à proximité du liquide de nettoyage projeté 7 qui nuisent à l'écoulement du liquide de lavage 7 le long de la lame d'essuyage 3. Des tests ont montrés que pour une longueur de balai d'essuie-glace 1 donnée, le liquide de nettoyage 7 s'écoule sur 100% de la longueur du balai d'essuie-glace 1 lorsque le véhicule est à l'arrêt, tandis que le liquide de nettoyage 7 ne s'écoule que sur 50% de la longueur du balai 1 lorsque le véhicule présente une vitesse d'avancement de 130 kilomètres par heure. Par conséquent, lorsque le véhicule est en état d'avancement, les écoulements d'air 9 au niveau du liquide de nettoyage projeté 7 entraînent une distribution défectueuse du liquide de nettoyage 7 le long de la lame, la qualité du nettoyage de la vitre en étant affectée.Finally, the invention relates to a motor vehicle comprising at least one such windshield wiper. Other features and advantages of the invention will emerge clearly from the description which is given below, by way of indication and in no way limiting, with reference to the appended figures among which: FIG. 1 is a diagrammatic representation in perspective of the end of a wiper blade incorporating a cleaning liquid spraying system; FIG. 2 is a schematic sectional representation of the wiper blade of FIG. 1 along the line II-II illustrating the air flows from the vehicle advance, - Figure 3 is a schematic perspective view of a wiper of the invention, and - Figure 4 is a schematic perspective view of the wiper blade. ice of the invention taken at a section along the line IV-IV of Figure 3. Referring to Figure 1, the wiper blade of the invention incorporates means for spraying the cleaning liquid near é of the wiper blade. To do this, the wiper blade 1 has a longitudinal body 2 secured along its lower portion to a curved wiper blade 3 to fit the curve of the surface to be cleaned. The longitudinal body 2 and the wiper blade 3 extend along a transverse axis YY 'of the wiper blade 1 (FIG. 2). A liquid distribution nozzle 4 is attached to one end of the blade 1 and comprises, on the one hand, a delivery pipe for the cleaning liquid 5 connected to unrepresented cleaning liquid supply means, and on the other hand, a nozzle 6 capable of throwing the cleaning liquid 7 close to and along the wiping blade 3. As can be seen in FIG. 2, the cleaning liquid 7 is projected parallel to the wiping blade 3 to proximity both of said blade 3 and the surface to be cleaned 8. As shown in Figure 2 and in known manner, a wiper blade has a metal vertebra 10 fitted in a longitudinal blind housing 11 made in the thickness of the body 2 of the wiper blade 1. The metal vertebra 10 does not oppose the curve of the wiper blade 3 previously mentioned. With reference to FIG. 2, the advance of the vehicle causes the formation of airflows 9 in the vicinity of the projected cleaning liquid 7 which impede the flow of the washing liquid 7 along the wiper blade 3 Tests have shown that for a given wiper blade length 1, the cleaning liquid 7 flows over 100% of the length of the wiper blade 1 when the vehicle is stationary, while the cleaning liquid 7 flows only 50% of the length of the blade 1 when the vehicle has a forward speed of 130 km / h. Therefore, when the vehicle is in the state of progress, the air flows 9 in the projected cleaning liquid 7 cause a defective distribution of the cleaning liquid 7 along the blade, the quality of the cleaning of the glass being affected.

On se réfère aux figures 2 et 3 pour décrire le balai d'essuie glace de l'invention 20. Le balai d'essuie-glace de l'invention 20 comporte un corps longitudinal 21 et une lame d'essuyage 22 réalisés en une seule pièce en un matériau thermoplastique.2 and 3 to describe the wiper blade of the invention 20. The wiper blade of the invention comprises a longitudinal body 21 and a wiper blade 22 made in one wiper blade. piece made of a thermoplastic material.

Le système de projection du liquide de nettoyage est identique, bien que non représenté sur ces figures, à celui précédemment décrit en référence aux figure 1 et 2 de sorte que le liquide de nettoyage projeté 23 s'écoule le long et à proximité de la lame d'essuyage 22 et de la surface à nettoyer 24. Le balai d'essuie-glace de l'invention 20 comporte deux vertèbres, une vertèbre principale 25 et une vertèbre secondaire 33. Ces deux vertèbres 25, 33 sont réalisées en un matériau métallique et présentent chacune une épaisseur suffisamment fine permettant ne pas s'opposer au galbe de la lame d'essuyage 22.The projection system of the cleaning liquid is identical, although not shown in these figures, to that previously described with reference to FIGS. 1 and 2 so that the projected cleaning liquid 23 flows along and close to the blade The wiper blade of the invention comprises two vertebrae, a main vertebra 25 and a secondary vertebra 33. These two vertebrae 25, 33 are made of a metallic material. and each have a thickness sufficiently fine not to oppose the curve of the wiper blade 22.

La vertèbre principale longitudinale 25 s'étend du coté du liquide de nettoyage projeté 23 depuis un premier bord longitudinal 26 situé à proximité de la surface à nettoyer 24 jusqu'au bord longitudinal opposé 27 qui est emmanché dans un logement borgne longitudinal 28 réalisé dans l'épaisseur du corps 21 du balai 20. Selon cette configuration, la vertèbre principale 25 présente une zone coudée 29 qui protège le liquide de nettoyage projeté 23 des écoulements d'air 32 issus de la vitesse d'avancement du véhicule, étant entendu que la partie 30 de la vertèbre principale 25 située entre le bord longitudinal opposé 27 et la zone coudée 29 est perpendiculaire à l'axe transversal YY' du balai d'essuie-glace 20. De préférence, afin de ne pas limiter le galbe de lame d'essuyage 22, le bord longitudinal 26 de la vertèbre principale 25 situé à proximité de la surface à nettoyer 24 du coté du liquide de nettoyage projeté 23, comporte une série de zones discontinues 31 régulièrement réparties tout le long du balai d'essuie-glace (figure 3). Chaque zone discontinue 31 présente une largeur la plus fine possible afin que la zone coudée 29 assure au mieux sa fonction de protection du liquide de nettoyage projeté 23 des écoulements d'air 32, tout en conservant à la vertèbre principale 25 sa qualité de ne pas s'opposer au galbe de la lame d'essuyage 22.The main longitudinal vertebra 25 extends on the side of the projected cleaning liquid 23 from a first longitudinal edge 26 located near the surface to be cleaned 24 to the opposite longitudinal edge 27 which is fitted into a longitudinal blind housing 28 formed in the The thickness of the body 21 of the blade 20. According to this configuration, the main vertebra 25 has a bent zone 29 which protects the projected cleaning liquid 23 from the air flows 32 originating from the forward speed of the vehicle, it being understood that the part 30 of the main vertebra 25 located between the opposite longitudinal edge 27 and the bent zone 29 is perpendicular to the transverse axis YY 'of the wiper blade 20. Preferably, in order not to limit the blade curve of wiping 22, the longitudinal edge 26 of the main vertebra 25 located near the surface to be cleaned 24 on the side of the projected cleaning liquid 23, comprises a series of zones discont Inues 31 are regularly distributed all along the wiper blade (Figure 3). Each discontinuous zone 31 has the thinnest possible width so that the bent zone 29 best serves its function of protecting the projected cleaning liquid 23 from the air flows 32, while retaining at the main vertebra 25 its quality of not oppose the curve of the wiper blade 22.

Par ailleurs, chaque zone discontinue 31 présente la forme d'une rainure 31 qui s'étend transversalement le long de la zone coudée 29 jusqu'au bord longitudinal 26 de la vertèbre principale 25 située à proximité de la surface à nettoyer 24 du coté du liquide de nettoyage projeté 23, de sorte que le bord longitudinal 26 de la vertèbre principale 25 présente ainsi une structure en forme de peigne. Comme visible sur la figure 4, le balai d'essuie-glace de l'invention 20 comporte en outre une seconde vertèbre 33 située du coté opposé au liquide de nettoyage projeté 23 et qui s'étend perpendiculairement à l'axe transversal YY' depuis un bord longitudinal 34 emmanché dans un logement borgne longitudinal 35 réalisé dans l'épaisseur du corps 21 du balai 20 jusqu'au bord longitudinal libre opposé 36 situé à distance de la surface à nettoyer 24. Les bords longitudinaux respectifs 27, 34 de la vertèbre principale 25 et de la vertèbre secondaire 33 qui sont emmanchés dans les logements borgnes respectifs 28,35 se font faces selon un plan P perpendiculaire à l'axe transversal YY' du balai d'essuie-glace de l'invention 20. En référence à la figure 3, l'essuie-glace de l'invention 40 comporte un levier d'essuie-glace 41 à l'extrémité duquel est monté le balai d'essuie glace 20 précédemment décrit. Lors de l'utilisation de l'essuie-glace 40, le levier d'essuie- glace 41 pivote autour d'un axe non représenté entraînant le balai d'essuie-glace 20 en déplacement contre la surface à nettoyer, en l'occurrence la vitre concernée du véhicule. Il résulte de la structure du balai d'essuie-glace de l'invention 20 telle que précédemment décrite que la vertèbre principale 25 permet à la fois de protéger le liquide de nettoyage projeté 23 des écoulements d'air 32 tout en contribuant à conserver le galbe de la lame d'essuyage 22, ce qui a pour conséquence une qualité améliorée de distribution du liquide de nettoyage et de nettoyage de la vitre.Furthermore, each discontinuous zone 31 has the shape of a groove 31 which extends transversely along the bent zone 29 to the longitudinal edge 26 of the main vertebra 25 located near the surface to be cleaned 24 on the side of the projected cleaning liquid 23, so that the longitudinal edge 26 of the main vertebra 25 thus has a comb-like structure. As can be seen in FIG. 4, the wiper blade of the invention further comprises a second vertebra 33 located on the opposite side to the projected cleaning liquid 23 and extending perpendicular to the transverse axis YY 'from a longitudinal edge 34 fitted in a longitudinal blind housing 35 formed in the thickness of the body 21 of the blade 20 to the opposite free longitudinal edge 36 located at a distance from the surface to be cleaned 24. The respective longitudinal edges 27, 34 of the vertebra 25 and the secondary vertebra 33 which are fitted into the respective blind housings 28,35 face in a plane P perpendicular to the transverse axis YY 'of the wiper blade of the invention 20. Referring to Figure 3, the wiper of the invention 40 comprises a wiper lever 41 at the end of which is mounted the wiper blade 20 previously described. When using the windscreen wiper 40, the windscreen wiper lever 41 pivots around an axis (not shown) causing the windscreen wiper blade 20 to move against the surface to be cleaned, in this case the relevant window of the vehicle. It results from the structure of the wiper blade of the invention as previously described that the main vertebra 25 both protects the projected cleaning liquid 23 from the air flows 32 while helping to maintain the curve of the wiper blade 22, which results in improved quality of distribution of the cleaning liquid and cleaning the glass.

Par ailleurs, l'utilisation d'une vertèbre pour former un moyen de protection du liquide de nettoyage projeté contre les écoulements d'air issus de l'avancement du véhicule est avantageux en terme de fabrication et de coût.Furthermore, the use of a vertebra to form a protective means of the cleaning liquid sprayed against the air flows from the vehicle advance is advantageous in terms of manufacture and cost.
