Description

SYSTEME D'ESSUYAGE D'UNE VITRE, NOTAMMENT VITRE ARRIERE DE  SYSTEM FOR WIPING A GLASS, IN PARTICULAR BACK GLASS OF
VEHICULE AUTOMOBILE  MOTOR VEHICLE
Le secteur technique de la présente invention est celui des systèmes 5 d'essuyage d'une vitre d'un véhicule, notamment automobile. Le système conforme à l'invention est plus particulièrement destiné à être installé sur une vitre ou lunette arrière du véhicule. The technical sector of the present invention is that of systems 5 for wiping a window of a vehicle, in particular an automobile. The system according to the invention is more particularly intended to be installed on a window or rear window of the vehicle.
En matière d'essuyage des vitres d'une automobile, l'accent est souvent mis î o sur l'essuyage du pare-brise. Cependant, l'essuyage de la vitre arrière ne doit pas être oublié. Il sert en effet à assurer au conducteur une vision dégagée du trafic à l'arrière du véhicule ou en cas de marche arrière. Alors que les balais d'essuyage pou r pare-brise sont généra lement amovi bl es pa r ra pport à l eu r bras d'entraînement pour permettre le remplacement du seul balai en cas d'usure, 15 dans le cas de système pour vitre-arrière, il est plus usuel de remplacer un ensemble formé à la fois du balai d'essuyage et du bras d'entrainement. Ledit ensemble est pour cela rendu amovible par rapport à un moyeu ou dispositif d'actionnement du bras. When wiping the windows of an automobile, the focus is often on the wiping of the windshield. However, wiping the rear window should not be forgotten. It serves to ensure the driver an unobstructed view of the traffic at the rear of the vehicle or in case of reverse. While the windshield wipers are generally provided with the drive arm to allow the replacement of the broom only in case of wear, in the case of a system for rear window, it is more usual to replace a set formed both wiper blade and the drive arm. Said assembly is for this reason made removable with respect to a hub or device for actuating the arm.
20 Par ailleurs, pour assurer un essuyage efficace, il est nécessaire que le balai soit appliqué avec un certain effort contre la vitre. Différentes solutions ont déjà été proposées en ce sens, notamment à l'aide d'une pièce rapportée tel qu'un ressort spiral appliquant un effort entre le dispositif d'actionnement et le bras. Un besoin d'amélioration demeure cependant, en particulier en termes deFurthermore, to ensure effective wiping, it is necessary that the blade be applied with a certain force against the window. Various solutions have already been proposed in this sense, in particular with the aid of an insert such as a spiral spring applying a force between the actuating device and the arm. However, a need for improvement remains, particularly in terms of
25 facilité de montage/démontage de l'ensemble bras-balai. 25 ease of assembly / disassembly of the arm-brush assembly.
L'invention vise à pallier les inconvénients précités et propose à cet effet un dispositif système d'essuyage d'une vitre, notamment de véhicule automobile, comprenant un balai d'essuyage et un bras d'entrainement dudit balai, ledit balai 30 comprenant une lame d'essuyage et une ou des vertèbres de rigidification de lad ite lame d'essuyage, led it bras s'étendant à partir d'une extrém ité, d ite proximale, de la ou desdites vertèbres, ledit bras étant configuré pour appliquer ledit balai sur ladite vitre. The invention aims to overcome the aforementioned drawbacks and proposes for this purpose a device for wiping a window, particularly a motor vehicle, comprising a wiper blade and a drive arm of said blade, said blade 30 comprising a wiper blade and one or more stiffening vertebrae of said wiper blade, said arm extending from an end, proximal dite, of said one or more vertebrae, said arm configured to apply said broom on said window.
En servant du bras lui-même pour appliquer le balai sur la vitre, on simplifie le système. On facilite en outre le changement de l'ensemble bras-balai. By using the arm itself to apply the broom to the glass, the system is simplified. It also facilitates the change of the arm-brush assembly.

Ledit système pourra également comprendre ledit dispositif d'actionnement. Selon un mode de réalisation avantageux, ce dernier comprend un corps, articulé en rotation autour d'un axe de pivotement et apte à recevoir ledit bras, et un 25 moyen de verrouillage dudit bras sur ledit corps. Said system may also include said actuating device. According to an advantageous embodiment, the latter comprises a body, articulated in rotation about a pivot axis and adapted to receive said arm, and a locking means of said arm on said body.
Ledit moyen de verrouillage pourra être articulé en rotation sur ledit corps, en particulier selon un axe d'articulation, transversal audit axe de pivotement du corps. On d ispose de la sorte d'u ne sol ution permettant u n montage et 30 démontage facile du bras et, par suite, du balai. Il s'agit en outre d'une solution qui facilite l'utilisation d'un dispositif d'aspersion de liquide de lavage intégré au balai. Avantageusement, ledit corps est configuré pour positionner ledit bras avant verrouillage, nota m ment à l'aide desdites ailes prévues su r la languette configurée pour être reliée au dispositif d'actionnement. Said locking means may be articulated in rotation on said body, in particular along an axis of articulation transverse to said axis of pivoting of the body.

Comme illustré aux figures 1 à 3, l'invention concerne un système d'essuyage d'une vitre de véhicule, ici d'une vitre arrière de véhicule automobile. 5 Ledit système comprend un balai d'essuyage 3 et un bras d'entraînement 2 dudit balai d'essuyage 3. As illustrated in Figures 1 to 3, the invention relates to a wiper system of a vehicle window, here a rear window of a motor vehicle. Said system comprises a wiper blade 3 and a drive arm 2 of said wiper blade 3.
Le balai d'essuyage 3, lorsqu'il est monté sur le véhicule, est en appui contre une face extérieure de la vitre arrière du véh icule. La vitre arrière î o mentionnée ici est un exemple d'une vitre essuyée par le système d'essuyage selon l'invention, mais il va de soi que cette vitre peut être un pare-brise du véhicule et d'une manière générale tout vitrage d'un véhicule automobile dont la surface est apte à être essuyée par un système d'essuyage. The wiper blade 3, when mounted on the vehicle, bears against an outer face of the rear window of the veh icule. The rear window 1 o mentioned here is an example of a window wiped by the wiper system according to the invention, but it goes without saying that this window can be a windshield of the vehicle and in general all glazing of a motor vehicle whose surface is able to be wiped by a wiper system.
15 Ledit système est avantageusement destiné à être positionné sur le véhicule de façon à ce q ue led it bala i d 'essuyage 3, a u repos , so it en position sensiblement horizontale, par exemple, le long d'un bord inférieur de la vitre arrière. En fonctionnement, il pivote alors selon un mouvement de va et vient entre sa position de repos et une position angulairement décalée de laditeSaid system is advantageously intended to be positioned on the vehicle so that it wipes the wiper 3, at rest, so it in substantially horizontal position, for example, along a lower edge of the rear window . In operation, it then pivots in a movement back and forth between its rest position and a position angularly offset from said
20 position de repos de façon à essuyer la zone souhaitée. 20 rest position so as to wipe the desired area.
Comme cela est plus particulièrement visi ble à la fig u re 2, le balais d'essuyage 3 comprend une lame d'essuyage ou raclette 4 destinée à être plaquée contre la vitre arrière et une ou plusieurs vertèbres 6, ici deux, de 25 rigidification de la lame 4, rel iées à ladite lame 4 et qui s'étendent le long de celle-ci. Ledit balai pourra en particulier être de type à lame plate (flat blade, en anglais). Autrement dit, il pourra s'agir d'un balai dans lequel la ou les vertèbres 6, naturellement cintrées, confèrent une forme légèrement oblique au balai 3. As is more particularly visible in FIG 2, the wiper blade 3 comprises a wiper blade or scraper 4 intended to be pressed against the rear window and one or more vertebrae 6, here two, stiffening of the blade 4, reléées said blade 4 and extending along it. Said broom may in particular be of type flat blade (flat blade, in English). In other words, it may be a broom in which the vertebrae 6 or, naturally curved, give a slightly oblique shape to the broom 3.
30 D'un côté, en l'occurrence à gauche sur la figure 2, la raclette 4 et les vertèbres 6 pourront présenter des extrémités axiales situées en vis-à-vis tandis qu'à leurs extrémités opposées, les vertèbres 6 s'étendent axialement au-delà de la raclette 4. On one side, in this case on the left in FIG. 2, the squeegee 4 and the vertebrae 6 may have axial ends located opposite each other while at their opposite ends the vertebrae 6 extend axially beyond the raclette 4.
Ledit système d'essuyage comprend en outre ici un embout d'assemblage 8 permettant de solidariser la raclette 4 et les vertèbres 6 au niveau de leurs 5 extrémités situées en vis-à-vis ainsi que, ici, un cache 64 des vertèbres 6 et d'une partie supérieure de la raclette 4 (figures 1 et 3). A leur autre extrémité, les vertèbres 6, en particulier leur partie dépassant axialement de la raclette 4, sont solidarisées au bras d'entraînement 2, comme cela sera détaillé plus loin. î o Le balai d'essuyage 3 est mis en mouvement sur la vitre arrière du véhicule par un dispositif d'actionnement 1 dudit système d'essuyage, lui-même entraîné par un ensemble d'actionnement comprenant, par exemple, un moteur électrique, avantageusement électronisé, chargé de transformer l'énergie électrique en un mouvement de rotation. Said wiper system further comprises here an assembly nozzle 8 for securing the squeegee 4 and the vertebrae 6 at their ends facing each other, as well as, here, a cover 64 of the vertebrae 6 and an upper portion of the squeegee 4 (Figures 1 and 3). At their other end, the vertebrae 6, in particular their axially projecting portion of the squeegee 4, are secured to the drive arm 2, as will be detailed below. The wiper blade 3 is moved on the rear window of the vehicle by an actuating device 1 of said wiper system, itself driven by an actuating assembly comprising, for example, an electric motor, advantageously electronically, responsible for transforming the electrical energy into a rotational movement.

Ledit bras 2 pourra alors comprendre des orifices 48 de passage situés dans le prolongement desdits orifices de fixation 44. La fixation du capot 46 sur le corps 10 est ainsi réalisée par l'introduction d'ergots, non visibles, situés à l'intérieur dudit capot 46, dans lesdits orifices de fixation 44 à travers les orifices de passage 48. Said body 10 may comprise one or more orifices 44 for fixing said cover 46 of said wiper system. Said fixing orifices 44 are located, for example, between the bar 26 and the distal end 32 of the body 10, in the locked position. Said arm 2 may then comprise orifices 48 of passage located in the extension of said fixing holes 44. The fixing of the cover 46 on the body 10 is thus achieved by the introduction of not visible pins, located at the inside of said cover 46, in said fixing holes 44 through the through openings 48.
Cela étant, selon l'invention, ledit bras 2 s'étend à partir de l'une des 5 extrémités de la ou desdites vertèbres 6, ici leurs extrémités opposées à celles munies dudit embout 8. Ledit bras est configuré pour appliquer ledit balai 3 sur ladite vitre. That being so, according to the invention, said arm 2 extends from one of the 5 ends of said vertebrae 6, here their opposite ends to those provided with said tip 8. Said arm is configured to apply said blade 3 on said window.
Ledit bras 2 pourra en particulier présenter en ce sens effet ressort. Il est î o réalisé pour cela, par exemple, en un matériau résiliant, notamment un matériau métallique présentant une élasticité appropriée. Il présente un profil en forme de S aplati muni de deux languettes 50, 52, ici parallèles, reliées par une branche oblique 54. Lesdites languettes 50, 52 et ladite branche oblique 54 sont issues de matière. Elles présentent une même largeur et/ou une même épaisseur, le choix 15 de ladite épaisseur participant à l'effet ressort du bras 2. Said arm 2 may in particular present in this sense spring effect. For this purpose, for example, it is made of a resilient material, in particular a metallic material having a suitable elasticity. It has a flattened S-shaped profile provided with two tabs 50, 52, here parallel, connected by an oblique branch 54. Said tabs 50, 52 and said oblique branch 54 are made of material. They have the same width and / or the same thickness, the choice of said thickness participating in the spring effect of the arm 2.
L'une 50 des languettes forme l'extrémité proximale du bras 2. Elle est reliée audit dispositif d'actionnement 1 , en position verrouillée, en venant être pris en sandwich entre ledit méplat 28 du corps 10 et ladite barrette 26 du moyen 14 de 20 verrouillage. Ladite première languette 50 est munie desdits ailes 40 du bras 2 et desdits orifices 48 de passage des ergots du capot 46. Ladite première languette pourra comporter un têton 56 destiné à coopérer avec une rainure 58 prévu dans le corps 10 en direction dudit logement 15 du corps 10.

Il peut en particulier s'agir d'une rampe 60 formée dans le cache 64 du bala i 3. Selon un autre 15 exemple de réalisation, ladite rampe d'aspersion pourra être formée par un conduit intégré à la raclette 4, et qui chemine le long de la direction longitudinale de ce dernier. According to an exemplary embodiment, said projection ramp 60 is manufactured separately from the squeegee 4, and attached thereto. It may in particular be a ramp 60 formed in the cover 64 of the bala i 3. According to another exemplary embodiment, said spray boom may be formed by a duct integrated in the squeegee 4, and which runs along the longitudinal direction of the latter.
Ledit dispositif d'aspersion pourra être configuré pour asperger ladite vitre 20 depuis ledit balai 3 selon une première et/ou une seconde direction d'aspersion opposée. Autrement dit, une dite rampe d'aspersion pourra être située de chaque côté dudit balai 3 pour asperger la vitre par un premier et/ou un second desdits côtés, notamment en fonction du sens ascendant ou descendant du balai 3. Said spray device may be configured to spray said window 20 from said brush 3 in a first and / or second opposite direction of spray. In other words, a said spray boom may be located on each side of said brush 3 to spray the glass by a first and / or second of said sides, in particular according to the upward or downward direction of the blade 3.
25 Si l'on se reporte de nouveau aux figures 4 et 5, on constate que ledit dispositif d'aspersion comprend en outre ici un circuit d'alimentation de la ou desdites rampes d'aspersion. Ledit circuit d'alimentation comprend, par exemple, un conduit flexible 70, reliant un embout de connexion hydraulique 72 prévu au niveau dudit bras 2 et/ou dudit balai 3, d'une part, et, d'autre part, une arrivée 74Referring again to FIGS. 4 and 5, it can be seen that said spraying device further comprises a supply circuit for the one or more spray bars.
