Description

"Agencement pour le montage d'un dispositif d'essuyage a mouvement"Arrangement for mounting a motion wiper device

elliptique" L'invention concerne un agencement pour le montage d'un dispositif d'essuyage du type a mouvement elliptique sur un element de structure d'un vehicule automobile. L'invention propose plus particulierement un agencement pour un dispositif d'essuyage d'une face transversale arriere d'un panneau vitre d'orientation principale transversale, sur un element de structure globalement parallele au panneau vitre, sur lequel le io panneau vitre est fixe et dont une face transversale arriere de ['element de structure comporte un logement en creux d'orientation principale longitudinale, dont le fond transversal est decale longitudinalement vers ['avant par rapport a la face transversale arriere de ['element de structure, le dispositif 15 d'essuyage comportant un mecanisme d'entrainement qui est monte sur une face transversale avant de ['element de structure, et qui comporte un arbre d'entrainement d'axe principal longitudinal A traversant un orifice realise dans le fond du logement en creux, de maniere que I'extremite arriere libre de 20 ['arbre d'entrainement est revue dans le logement en creux, un dispositif de transformation de mouvement, qui est monte sur I'extremite arriere libre de ('arbre d'entrainement, dans le logement en creux, et qui comporte un arbre de sortie d'axe principal B longitudinal decale radialement par rapport a I'axe 25 longitudinal A et mobile a rotation autour de ['axe longitudinal A et autour de son axe principal B, et un bras d'entrainement d'un balai d'essuyage de la face transversale arriere du panneau vitre, qui est monte sur ['arbre de sortie du dispositif de transformation de mouvement. 30 Les evolutions recentes des panneaux vitres avant et arriere des vehicules automobile ont generalement pour resultat que les dimensions du panneau vitre avant d'un vehicule 2 automobile, aussi appele pare-brise, augmentent, tandis que les dimensions du panneau vitre arriere diminuent. Ainsi, le panneau vitre arriere d'un vehicule est generalement de forme allongee transversalement avec une hauteur verticale relativement reduite. Les dispositifs d'essuyage classiques, pour lesquels le balai d'essuyage effectue un mouvement globalement circulaire, sont particulierement adaptes aux panneaux vitres ayant une hauteur verticale et une largeur transversale globalement io similaires ou ayant une hauteur verticale legerement plus faible que la largeur transversal. En effet, c'est la plus petite dimension du panneau vitre qui permet de definir les caracteristiques dimensionnelles du mecanisme d'essuyage. 15 Ainsi, un mecanisme d'essuyage a mouvement circulaire est peu adapte a un panneau vitre dont la hauteur est nettement plus faible que sa largeur. Pour remedier a une telle difficulte, it est connu d'utiliser des dispositifs d'essuyage pour lesquels le deplacement du balai 20 d'essuyage s'effectue selon une trajectoire en forme d'une portion d'ellipse. Le document US-A-6.557.205 decrit un tel dispositif d'essuyage a mouvement elliptique comportant un mecanisme d'entrainement compose principalement d'un motoreducteur a 25 arbre de sortie globalement longitudinal, et un dispositif de transformation du mouvement de rotation de I'arbre d'entrainement en un mouvement elliptique du bras d'essuyage. Ce dispositif de transformation de mouvement comporte un premier pignon fixe coaxial a I'arbre d'entrainement et un 30 ensemble de pignons mobiles qui sont montes sur un support mobile solidaire de I'arbre d'entrainement. Un arbre de sotie de ce dispositif de transformation de mouvement est solidaire de run des pignons mobiles et porte le 3 balai d'essuyage pour son entrainement en mouvement de balayage elliptique. Selon ce document, le dispositif d'essuyage est monte sur un element de structure du vehicule, qui consiste globalement en une tole pliee et emboutie, qui porte, sur sa face verticale transversale externe le panneau vitre. Le motoreducteur est ainsi monte sur une face interne de ('element de structure, et le dispositif de transformation de mouvement est monte sur la face arriere de I'element de io structure. L'element de structure comporte en outre un logement en creux qui debouche vers I'arriere dans la face arriere de ('element de structure, et dont le fond vertical transversal de ce logement en creux est decale longitudinalement vers ('avant. 15 Le dispositif de transformation de mouvement est rep dans ce logement en creux, et est mobile en rotation autour de ('axe principal de I'arbre d'entrainement a I'interieur du logement en creux. Une telle disposition du dispositif de transformation de 20 mouvement a I'interieur du logement en creux permet de rendre ce dispositif de transformation de mouvement relativement discret. Cependant, la totalite du support mobile est accessible par n'importe quelle personne au niveau de I'ouverture arriere du 25 logement en creux. Ainsi, it y a un risque qu'une personne puisse toucher le support mobile, et se blesse, notamment lorsque le mecanisme d'essuyage est en fonctionnement. De plus, selon ce document, le mecanisme d'entrainement 30 et le dispositif de transformation de mouvement sont mantes longitudinalement de chaque cote de ('element de structure, et de maniere sepal-6e. 4 Ainsi, le montage du dispositif d'essuyage sur ('element de structure s'effectue suivant deux operations successives, ce qui augmente la duree totale d'assemblage du vehicule automobile. L'invention a pour but de proposer un agencement pour le montage d'un tel dispositif d'essuyage a mouvement elliptique, dans lequel le mecanisme d'entrainement est dissimule de maniere a garantir une securite suffisante vis-a-vis des personnes, et de maniere a ameliorer I'esthetique generale du vehicule.  The invention relates to an arrangement for mounting an elliptical-type wiping device on a structural element of a motor vehicle, and more particularly the invention provides an arrangement for a wiper device. a transverse rear face of a glass panel of transverse main orientation, on a structural element generally parallel to the glass panel, on which the glass panel is fixed and a rear transverse face of the structural element comprises a housing trough of longitudinal main orientation, whose transverse bottom is shifted longitudinally forwardly relative to the rear transverse face of the structural element, the wiper device comprising a drive mechanism which is mounted on one side transverse front of the structural element, and which comprises a longitudinal axis main drive shaft A through an orifice made in the bottom of the housing in c in such a way that the rear end of the drive shaft is recessed in the hollow housing, a motion-transforming device which is mounted on the rear end of the drive shaft, in the hollow recess, and which has an output shaft of main axis B longitudinal shifts radially relative to the longitudinal axis A and rotatable about the longitudinal axis A and about its main axis B, and a drive arm of a wiper blade of the rear transverse face of the window panel, which is mounted on the output shaft of the motion transformation device. Recent developments in the front and rear window panels of motor vehicles have generally resulted in the size of the front window panel of a motor vehicle, also called the windshield, increasing, while the dimensions of the rear window panel are decreasing. Thus, the rear window panel of a vehicle is generally of transversely elongated shape with a relatively small vertical height. Conventional wiping devices, for which the wiper blade makes a generally circular movement, are particularly suitable for window panes having a generally similar vertical height and cross-sectional width or having a vertical height slightly smaller than the transverse width. Indeed, it is the smaller dimension of the glass panel that defines the dimensional characteristics of the wiper mechanism. Thus, a circular wiping mechanism is poorly adapted to a glass panel whose height is much smaller than its width. To remedy such a problem, it is known to use wiper devices for which the wiper 20 moves in a path in the form of an ellipse portion. US-A-6,557,205 discloses such an elliptical movement wiping device comprising a drive mechanism consisting mainly of a gear motor with a generally longitudinal output shaft, and a device for transforming the rotational movement of I drive shaft in an elliptical motion of the wiper arm. This motion transformation device comprises a first fixed gear coaxial with the drive shaft and a set of movable gears which are mounted on a movable support integral with the drive shaft. A sotie shaft of this motion transforming device is integral with run of the moving gears and carries the wiper blade 3 for its drive in elliptical sweeping motion. According to this document, the wiper device is mounted on a structural element of the vehicle, which consists generally of a folded and stamped sheet, which carries, on its vertical transverse outer face the glass panel. The gearmotor is thus mounted on an inner face of the structural element, and the motion transformation device is mounted on the rear face of the element of structure. opening towards the rear in the rear face of the structural element, and whose transverse vertical bottom of this recessed housing is shifted longitudinally towards the front The movement transformation device is rep in this recessed housing, and is rotatable about the main axis of the drive shaft within the recessed housing, and such an arrangement of the motion transformation device within the recessed housing makes this device However, the entire movable support is accessible by anyone at the rear opening of the recessed housing, so there is a risk can touch the mobile support, and is injured, especially when the wiper mechanism is in operation. In addition, according to this document, the driving mechanism 30 and the motion transformation device are longitudinally disposed on each side of the structural element, and in a sepal-6 manner. on the structural element is carried out following two successive operations, which increases the total duration of assembly of the motor vehicle.The object of the invention is to propose an arrangement for mounting such a movement wiper device. elliptical trainer, in which the driving mechanism is concealed so as to guarantee a sufficient safety towards the persons, and so as to improve the general aesthetics of the vehicle.

L'ouvrant arriere 10 comporte aussi un dispositif io d'essuyage de la face verticale transversale arriere 18a du panneau vitre 18, comportant notamment un bras 20 d'entrainement d'un balai d'essuyage 22 de la face arriere 18a du panneau vitre 18 et un mecanisme d'entrainement 22 du bras 20 en mouvement de balayage alterne par rapport au panneau 15 vitre 18. Comme on peut le voir a la figure 4, le mecanisme d'entrainement 24 est monte sur une face verticale transversale avant 16a de ('element de structure 12, qui est ici la face verticale avant 16a de la deuxieme tole 16. 20 Le mecanisme d'entrainement 24 est un moto reducteur de type connu, comportant un moteur electrique dont ('axe principal s'etend dans un plan vertical transversal, et un reducteur qui est monte sur I'arbre de sortie du moteur electrique, et qui comporte un arbre d'entrainement 26 d'axe principal A longitudinal qui 25 s'etend vers ('arriere en traversant un premier orifice associe 28 de la deuxieme tole 16, et un deuxieme orifice associe 30 realise dans la premiere tole 14. Le dispositif d'essuyage est realise de maniere que le bras d'entrainement 20 est mobile par rapport a la face arriere 18a du 30 panneau vitre 18 selon une trajectoire en forme d'une portion d'ellipse. Pour obtenir un tel mouvement du bras d'entrainement, le dispositif d'essuyage comporte en outre un dispositif 32 de 8 transformation du mouvement de rotation de I'arbre d'entrainement 26 en un mouvement elliptique, qui est agence entre le bras d'entrainement 20 et la I'arbre d'entrainement 26.

It will also adopt the forward-backward orientation as being the longitudinal direction and from right to left with reference to Figure 4. In the description which In the following, identical, similar or similar elements will be indicated by the same reference numerals: FIGS are shown a rear opening 10 of a motor vehicle, in particular a rear hatch, which extends vertically transversely to the rear of the vehicle and which is mounted articulated relative to the vehicle body around a transverse axis (not shown) .The opening comprises a structural element 12 which is constituted of a first rear panel 14 which extends mainem in a vertical transverse plane, which is shaped by cutting and bending. The structural element 12 may also be made of composite material. As can be seen in FIG. 4, the structural element 12 comprises a second front panel 16 which is generally parallel to the first rear panel 14, which is also shaped by cutting and folding, and which is located longitudinally at a distance from the first rear panel 14. The rear opening 10 comprises a glass panel 18 which extends generally in a transverse vertical plane, and which is mounted on the first sheet 14 so that it closes an opening (not shown). ) which is made in the rear panel 14. The rear opening 10 also comprises a device wiping the rear transverse vertical face 18a of the glass panel 18, including an arm 20 for driving a wiper blade 22 of the rear face 18a of the glass panel 18 and a drive mechanism 22 of the arm 20 in alternate scanning movement with respect to the glass panel 18. As can be seen in FIG. 4, the driving mechanism 24 is goes up on a college The driving mechanism 24 is a reduction motor of the known type, comprising an electric motor whose axis (16) is the transverse vertical front 16a of the structural element 12, which is here the vertical front face 16a of the second plate 16. main stretcher extends in a transverse vertical plane, and a reducer which is mounted on the output shaft of the electric motor, and which comprises a drive shaft 26 of main axis A longitudinal which extends to the back passing through a first associated orifice 28 of the second sheet 16, and a second associated orifice 30 made in the first sheet 14. The wiper is made so that the drive arm 20 is movable relative to the rear face 18a of the glass panel 18 along a path in the form of an ellipse portion. To obtain such a movement of the driving arm, the wiper device further comprises a device 32 for transforming the rotational movement of the drive shaft 26 into an elliptical movement, which is arranged between the arm of the drive arm. 20 and the drive shaft 26. The motion transformation device 32 is of known type, for example of the type of device described in US-A-6,557,205 to which reference will be made for more details. The motion transformation device is constructed so that the main axis B of the output shaft 38 is offset radially from the longitudinal axis A of the drive shaft 26, and so that In the operation of the wiper device, the output shaft 38 is able to rotate simultaneously about the longitudinal axis A of the drive shaft 26, and about its main axis B. As can be seen in the figures The structural element 12 comprises a hollow recess 40 which is formed in the first rear wall 14, so that the transverse vertical bottom 42 of this hollow recess 40 is offset longitudinally towards the front with respect to the vertical plane. transverse main face 14a of the first sheet 14.

According to one embodiment, the recessed housing 40 is cylindrical in shape of circular section and it is coaxial a longitudinal main axis A of the drive shaft 26. Also, the orifice 30 which is made in the rear panel 14, is made in the bottom 42 of the recessed housing 40, as can be seen more FIG. 3. In accordance with the invention, the rear opening of the recessed housing 40 is closed by a closure disk 44 which extends in a transverse vertical plane behind the movement transformation device.

Ainsi, le disque de fermeture 44 ferme le logement en creux 40 en empechant tout acces au dispositif de transformation de mouvement 32, de maniere a le proteger notamment d'eventuelles agressions exterieures. Selon un mode de realisation prefere, le disque de io fermeture 44 est de forme circulaire coaxiale a ('axe principal longitudinal A de I'arbre d'entrainement 26. De plus, le diametre exterieur du disque de fermeture est globalement egal au diametre interieur du logement en creux 40. Comme on peut le voir a la figure 2, le disque de fermeture 15 44 comporte une ouverture radiale 46 qui est traversee par I'arbre de sortie 38 du dispositif de transformation de mouvement 32. Selon un mode de realisation prefere, la largeur de ('ouverture radiale 46, mesuree tangentiellement par rapport a ('axe longitudinal A, est globalement egale au diametre de I'arbre 20 de sortie 38. Ainsi, le disque de fermeture 44 obture la totalite du logement en creux 40, sauf au niveau de ('ouverture 46 qui est situee angulairement autour de ('axe longitudinal A a la meme position que I'arbre de sortie 38. 25 Comme on I'a dit plus haut, I'arbre de sortie 38 est mobile en rotation autour de ('axe longitudinal A lors du fonctionnement du dispositif d'essuyage. Selon un autre aspect de ('invention, le disque de fermeture 44 est monte pivotant par rapport a ('element de 30 structure 12 autour de I'axe longitudinal A et de maniere solidaire de I'arbre de sortie 38. L'ouverture radiale 46 est apte a cooperer avec I'arbre de sortie 38 lors du fonctionnement du dispositif d'essuyage, pour io I'entraInement en rotation du disque de fermeture autour de ('axe longitudinal A. Ainsi, lors du fonctionnement du dispositif d'essuyage, le disque de fermeture 44 obture la majeure partie de I'ouverture d'extremite longitudinale arriere du logement en creux 40, mise a part la partie correspondant a I'ouverture radiale 46 du disque de fermeture 44, qui est situee a la meme position angulaire autour de ('axe longitudinale A que I'arbre de sortie 38. Comme on peut le voir a Ia figure 1, le disque de fermeture to 44 est monte articule autour de ('axe longitudinal A par I'intermediaire d'un cache arriere de montage 48 qui s'etend dans un plan vertical transversal situe longitudinalement en arriere du disque de fermeture 44. Le cache de montage 48 chevauche transversalement le 15 disque de fermeture 44, et it comporte deux pieds lateraux 50 par I'intermediaire desquels le cache de montage 48 est monte sur la tole arriere 14, ici par emboitement elastique d'un doigt longitudinal 52 qui est porte par chaque pied 50, dans un logement complementaire 54 realise dans la tole arriere 14. 20 De plus, comme on peut le voir a la figure 6, le cache de montage 48 comporte une tige longitudinale 56 coaxiale a I'axe longitudinal A, qui s'etend longitudinalement vers ('avant, et qui coopere avec un orifice associe 58 du disque de fermeture 44 pour ('articulation du disque de fermeture 44 par rapport au cache 25 de montage 48, et par consequent, par rapport a ('element de structure 12, en rotation autour de ['axe longitudinal A de I'arbre d'entrainement 26. D'une maniere generale, le panneau vitre 18 est un element de forme globalement rectangulaire, dont la plus grande 30 Iongueur est transversale. De plus, le dispositif d'essuyage a mouvement elliptique est realise de maniere que la portion d'ellipse formee par le balai 22 d'essuyage tors du fonctionnement du dispositif d'essuyage, 11 est elle aussi d'orientation principale transversale, c'est-a-dire que le grand axe de cette ellipse est globalement parallele a la direction transversale. Le dispositif d'essuyage est ainsi agence sur le hayon 10 au niveau d'un bord transversal d'extremite inferieure 18i du panneau vitro 18 et it est agence transversalement globalement au milieu de ce bord transversal inferieur 18i du panneau vitro. Selon un autre aspect de I'agencement selon I'invention, et comme on peut le voir plus en details a la figure 3, le logement en io creux 40 est realise sur la tole arriere 14 de maniere quill soit agence verticalement a proximite du bord transversal inferieur 18i du panneau vitro 18. Selon un mode de realisation prefere, le logement en creux 40 est agence verticalement de maniere qu'une portion du 15 panneau vitro 18 recouvre en partie I'ouverture d'extremite longitudinale arriere du logement en creux 40. Aussi, selon ce mode de realisation, le disque de fermeture 44 est agence longitudinalement par rapport au panneau vitro 18, de maniere que la portion du panneau vitro 18 qui recouvre en 20 partie I'ouverture d'extremite longitudinale arriere du logement en creux 40, recouvre aussi en partie le disque de fermeture 44. Un decrochement 60 est realise dans le bord inferieur 18i du panneau vitro 18, et le cache de montage 48 est apte a etre recu en partie a I'interieur de ce decrochement 60, pour donner a 25 I'agencement un aspect esthetique agreable. Pour cela, le cache de montage 48 est monte sur la tole arriere 14 de maniere que sa face verticale transversale arriere 48A affleure avec la face verticale transversale arriere 18a du panneau vitro 18, comme on peut le voir notamment aux figures 4 30 et 6. Comme on I'a dit plus haut, la tole arriere 14 et la tole avant 16 comportent chacune un orifice 30, 28 qui est traverse par I'arbre d'entrainement 26 du mecanisme d'entrainement 24. 12 Selon encore un autre aspect de ('invention, les formes et les dimensions de chacun de ces orifices 30, 28 sont determinees de maniere que le dispositif de transformation de mouvement 32 est apte a titre introduit dans le logement en creux 40 au travers de ces deux ouvertures 28, 30. Selon un premier mode de realisation de cette autre aspect de ('invention, et comme on peut le voir aux figures 2, 3 et 4, ('orifice 30 qui est realise dans le fond 42 du logement en creux 40 est de forme globalement oblongue et s'etend radialement par io rapport a I'axe longitudinal A de I'arbre d'entrainement 26. De plus, comme on peut le voir a la figure 2, le support mobile 36 comporte un premier logement cylindrique 62 qui est coaxial a ('axe longitudinal A de I'arbre d'entrainement 26, a I'interieur duquel le pignon fixe 34 est rep, et un logement radial 15 64 qui prolonge radialement le premier logement 62 par rapport a ('axe longitudinal A, et qui Porte les pignons et I'arbre de sortie 38 du dispositif de transformation de mouvement 32. Ici, lorsque le dispositif d'essuyage est en position de repos, ('axe principal radial du deuxieme logement radial 64 est 20 parallele a la direction transversale T. De plus, la largeur du deuxieme logement radial 64 qui est ici la dimension verticale de ce logement 64, est inferieure au diametre externe du premier logement cylindrique 62. Par consequent, selon ('invention, la largeur de ('orifice 30 25 qui est realisee dans le fond 42 du logement en creux 40, qui est ici la petite dimension de cet orifice oblong, est legerement superieure au diametre exterieur du premier logement cylindrique 62 du support mobile 36. De plus, la longueur transversale de cet orifice 30 est 30 legerement superieure a la longueur transversale globale du support mobile 36. L'ouverture 30 du fond 42 du logement en creux 40 est positionne angulairement autour de ('axe longitudinal A 13 globalement a la meme cote angulaire que le support mobile 36, lorsque le dispositif d'essuyage est en position de repose. Enfin, I'ouverture 28 qui est realisee dans la deuxieme tole avant 16 est de dimensions superieures a celles de I'orifice 30 qui est realise dans le fond 42 du logement en creux 40, et I'ouverture 28 est positionnee verticalement et transversalement globalement coaxialement a I'ouverture 30. Ainsi, lors du montage du dispositif d'essuyage sur ('element de structure 12, le dispositif de transformation de to mouvement 32 est introduit dans le logement en creux 40 selon un mouvement globalement longitudinal de I'avant vers I'arriere, en traversant successivement I'ouverture 28 qui est realisee dans la deuxieme tole avant 16, puis I'orifice 30 realise dans le fond 42 du logement en creux 40. 15 Enfin, ('orifice 30 qui est realise dans le fond 42 du logement en creux 40 est forme et est oriente de maniere qu'il corresponde globalement a la position du dispositif de transformation de mouvement lorsque le dispositif d'essuyage est dans sa position de repos. 20 Ainsi, tors du montage du dispositif d'essuyage sur ('element de structure 12, le mouvement du dispositif d'essuyage par rapport a ('element de structure 12 consiste en un seul mouvement de translation longitudinale, qui ne comporte pas de rotation autour d'un axe longitudinal. 25 Ceci permet donc de simplifier le processus d'assemblage du dispositif d'essuyage sur I'ouvrant arriere 10. De plus, un tel mode de montage du dispositif d'essuyage sur ('element de structure 12 permet d'assembler le dispositif de transformation de mouvement 32 sur le mecanisme 30 d'entrainement 24 prealablement a leur montage sur ('element de structure, par exemple par I'equipement entier qui est fournisseur du dispositif d'essuyage. 14 Comme on peut le voir a la figure 4, le dispositif d'essuyage comporte aussi une platine 66 de support et de montage du mecanisme d'entra?nement 24 et du dispositif de transformation de mouvement 32 sur ('element de structure 12.  Thus, the closure disc 44 closes the hollow housing 40 by preventing access to the motion-transforming device 32, so as to protect it in particular from possible external aggressions. According to a preferred embodiment, the closing disc 44 is coaxially circular in shape with the longitudinal main axis A of the drive shaft 26. In addition, the outer diameter of the closure disk is generally equal to the inside diameter. As can be seen in FIG. 2, the closure disc 44 has a radial opening 46 which is traversed by the output shaft 38 of the motion transformation device 32. According to one embodiment of the embodiment of FIG. Preferably, the width of the radial opening 46, measured tangentially with respect to the longitudinal axis A, is generally equal to the diameter of the output shaft 38. Thus, the closure disk 44 closes the entire hollow housing. 40, except at the opening 46 which is angularly located about the longitudinal axis A at the same position as the output shaft 38. As mentioned above, the output shaft 38 is mobile rotation about (longitudinal axis A lor s operation of the wiper device. In another aspect of the invention, the closure disc 44 is pivotally mounted relative to the structural member 12 about the longitudinal axis A and integrally with the output shaft 38. The radial opening 46 is adapted to cooperate with the output shaft 38 during operation of the wiper device, for the rotational engagement of the closure disk around the longitudinal axis A. Thus, during the operation of the wiper device , the closure disc 44 closes most of the rear longitudinal end opening of the recessed housing 40, apart from the portion corresponding to the radial opening 46 of the closure disc 44, which is located at the same position angularly around the longitudinal axis A that the output shaft 38. As can be seen in FIG. 1, the closure disc 44 is mounted articulated around the longitudinal axis A by means of a cover rear mounting 48 which extends in a transverse vertical plane It is located longitudinally behind the closure disc 44. The mounting cover 48 overlaps transversely the closure disc 44, and it has two lateral legs 50 through which the mounting cover 48 is mounted on the rear panel 14, here by elastic interlocking of a longitudinal finger 52 which is carried by each leg 50, in a complementary housing 54 made in the rear panel 14. In addition, as can be seen in FIG. Longitudinal rod 56 coaxial with the longitudinal axis A, which extends longitudinally towards the front, and which cooperates with an associated orifice 58 of the closure disk 44 for the articulation of the closing disk 44 with respect to the mounting plate 48, and therefore, with respect to the structural element 12, rotating about the longitudinal axis A of the drive shaft 26. Generally, the window panel 18 is a generally shaped element. rectangular, whose pl We have 30 long and transverse. In addition, the wiper device with elliptical movement is made in such a way that the portion of ellipse formed by the wiper blade 22 is wiped with the operation of the wiper device, 11 is also of transverse main orientation, that is, the major axis of this ellipse is generally parallel to the transverse direction. The wiper device is thus arranged on the tailgate 10 at a transverse edge of the lower end 18i of the panel 18 and it is transversely arranged overall in the middle of the lower transverse edge 18i of the panel. According to another aspect of the arrangement according to the invention, and as can be seen in more detail in FIG. 3, the hollow housing 40 is made on the rear panel 14 so that it is arranged vertically close to the edge. 18. In a preferred embodiment, the recessed housing 40 is vertically arranged so that a portion of the panel 18 partially covers the rear longitudinal end opening of the recessed housing 40. Also, according to this embodiment, the closure disc 44 is longitudinally arranged with respect to the panel 18, so that the portion of the panel 18 that partially covers the rear longitudinal end opening of the recessed housing. 40, also partially covers the closing disc 44. A recess 60 is made in the lower edge 18i of the glass panel 18, and the mounting cover 48 is able to be partially received inside this recess 60, to give the arrangement a pleasant aesthetic appearance. For this, the mounting cover 48 is mounted on the rear panel 14 so that its rear transverse vertical face 48A is flush with the rear transverse vertical face 18a of the panel 18, as can be seen in particular in Figures 4 and 6. As mentioned above, the rear panel 14 and the front panel 16 each have an orifice 30, 28 which is traversed by the drive shaft 26 of the driving mechanism 24. According to yet another aspect of (Invention, the shapes and dimensions of each of these orifices 30, 28 are determined so that the motion transformation device 32 is suitably introduced into the recessed housing 40 through these two openings 28, 30. According to a first embodiment of this other aspect of the invention, and as can be seen in FIGS. 2, 3 and 4, the orifice 30 which is made in the bottom 42 of the recessed housing 40 is of generally oblong shape. and extends radially with respect to the axis In addition, as can be seen in FIG. 2, the movable support 36 comprises a first cylindrical housing 62 which is coaxial with the longitudinal axis A of the drive shaft. 26, within which the fixed gear 34 is rep, and a radial housing 64 which radially extends the first housing 62 relative to (longitudinal axis A, and which carries the pinions and the output shaft 38 of the device In this case, when the wiper device is in the rest position, the radial principal axis of the second radial housing 64 is parallel to the transverse direction T. In addition, the width of the second radial housing 64 which here is the vertical dimension of this housing 64, is smaller than the outer diameter of the first cylindrical housing 62. Therefore, according to the invention, the width of the orifice 25 which is made in the bottom 42 of the recessed housing 40, which is here the small dimension of this oblo orifice ng, is slightly greater than the outside diameter of the first cylindrical housing 62 of the movable support 36. In addition, the transverse length of this orifice 30 is slightly greater than the overall transverse length of the movable support 36. The opening 30 of the bottom 42 of the The recessed housing 40 is angularly positioned around the longitudinal axis A 13 generally at the same angular dimension as the movable support 36 when the wiper device is in the rest position. Finally, the opening 28 which is made in the second sheet before 16 is of greater dimensions than those of the orifice 30 which is formed in the bottom 42 of the recessed housing 40, and the opening 28 is positioned vertically and transversely globally. Thus, when the wiper device is mounted on the structural element 12, the movement transformation device 32 is introduced into the recessed housing 40 in a generally longitudinal movement of the front. towards the rear, passing successively through the opening 28 which is made in the second sheet before 16, then the orifice 30 made in the bottom 42 of the recessed housing 40. Finally, the orifice 30 which is made in the The bottom 42 of the hollow recess 40 is shaped and is oriented so that it corresponds globally to the position of the motion transformation device when the wiper device is in its rest position. On wiping element 12, the movement of the wiper relative to the structural element 12 consists of a single longitudinal translational movement which does not rotate about a longitudinal axis. This thus makes it possible to simplify the assembly process of the wiper device on the rear opening 10. In addition, such a mounting mode of the wiper device on the structural element 12 makes it possible to assemble the device of FIG. Transformation of movement 32 on the drive mechanism 24 prior to their mounting on the structural element, for example by the entire equipment which is the supplier of the wiper device As can be seen in FIG. the wiper device also comprises a plate 66 for supporting and mounting the driving mechanism 24 and the movement-transforming device 32 on the structural element 12.

Ici, la platine 66 comporte une premiere portion plane 68 qui est monte sur la face avant 16a de le tole avant 16. Le mecanisme d'entrainement 24 est monte sur la face verticale transversale avant 68a de la portion plane 68, et le pignon fixe 34 du dispositif de transformation de mouvement est monte sur la face verticale transversale arriere 68b de cette portion plane 68. La platine 66 comporte aussi un fit cylindrique 70 qui s'etend longitudinalement vers I'arriere depuis la face verticale transversale arriere 68b de la portion plane 68, et qui est revue sans jeu dans I'ouverture 30 qui est realisee dans le fond 42 du logement en creux 40. La section du fit cylindrique 70, suivant un plan vertical transversal est par consequent complementaire de I'ouverture 30. De plus, un joint 72 annulaire est agence au niveau du bord de I'ouverture 30 et it est recu entre le fit 70 de la platine 66 et le bord de I'ouverture 30, de maniere a assurer une etancheite entre la tole arriere 14 et la platine 66. On a represents aux figures 5 et 6 une variante de realisation de ('invention selon laquelle le fit 70 de la platine de support 66 est de diametre globalement egal au diametre du logement en creux 40, et dans Iequel est regu ('ensemble du dispositif 32 de transformation de mouvement. De plus, comme on peut le voir plus en detail a la figure 6, le fond 42 du logement en creux 40 est agence longitudinalement en avant de la face arriere 14a de la tole arriere 14, et a proximite de celle-ci.  Here, the plate 66 includes a first flat portion 68 which is mounted on the front face 16a of the front plate 16. The drive mechanism 24 is mounted on the vertical transverse front face 68a of the flat portion 68, and the fixed gear 34 of the movement transformation device is mounted on the rear transverse vertical face 68b of this flat portion 68. The plate 66 also comprises a cylindrical fit 70 which extends longitudinally towards the rear from the rear transverse vertical face 68b of the portion 68, which is viewed without play in the opening 30 which is made in the bottom 42 of the recessed housing 40. The section of the cylindrical fit 70, in a transverse vertical plane is therefore complementary to the opening 30. De in addition, an annular seal 72 is provided at the edge of the opening 30 and is received between the end 70 of the plate 66 and the edge of the opening 30, so as to ensure a seal between the rear panel 14 and the dish 66. FIGS. 5 and 6 show an alternative embodiment of the invention in which the fit 70 of the support plate 66 is of a diameter generally equal to the diameter of the recessed housing 40, and in which it is received. set of the motion transformation device 32. In addition, as can be seen in more detail in FIG. 6, the bottom 42 of the recessed housing 40 is arranged longitudinally in front of the rear face 14a of the rear panel 14, and in proximity thereto.

15 L'ouverture 30 qui est realisee dans ce fond 42 est elle aussi circulaire, et son diametre est egal au diametre externe du fat 70 de la platine 66. Selon ce mode de realisation, I'ouverture 28 qui est realisee dans la deuxieme tole arriere 16 est identique a I'ouverture 30 realisee dans le fond 42 du logement en creux 40. Les deux ouvertures 28, 30, ainsi que le fat 70 de la platine de support 66 sont coaxiaux a ('axe principal longitudinal A de I'arbre d'entrainement 26 pour permettre le montage du io dispositif d'essuyage sur l'element de structure 12 selon un mouvement de translation de ('avant vers ('arriere, tel que decrit precedemment. Enfin, comme on I'a dit plus haut, le disque de fermeture 44 est de diametre exterieur globalement egal au diametre 15 interieur du logement en creux 40, et le diametre du fat 70 de la platine 66 est lui aussi inferieur au diametre interne du logement en creux 40. Par consequent, le disque de fermeture 44 selon I'invention obture aussi le fat 70 de la platine 66.The opening 30 which is made in this bottom 42 is also circular, and its diameter is equal to the outer diameter of the fat 70 of the plate 66. According to this embodiment, the opening 28 which is made in the second sheet rear 16 is identical to the opening 30 made in the bottom 42 of the recessed housing 40. The two openings 28, 30, as well as the fat 70 of the support plate 66 are coaxial with the longitudinal main axis A of FIG. drive shaft 26 to allow the wiper device to be mounted on the structural member 12 in a forward to back translation movement as previously described. high, the closure disk 44 is of external diameter generally equal to the inner diameter of the recessed housing 40, and the diameter of the fat 70 of the plate 66 is also lower than the internal diameter of the recessed housing 40. Therefore, the closing disc 44 according to the invention also closes the fat 70 platinum 66.
