Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
L'invention concerne, de façon générale, le domaine de l'équipement automobile. The invention relates generally to the field of automotive equipment.
Plus précisément, l'invention concerne, selon un premier de ses aspects, un déflecteur pour un véhicule automobile équipé d'un pare-brise présentant un bord supérieur, un bord inférieur et deux bords dressés. More specifically, the invention relates, according to a first of its aspects, a deflector for a motor vehicle equipped with a windshield having an upper edge, a lower edge and two raised edges.
Les déflecteurs, dont l'utilisation est bien connue dans l'industrie automobile, visent à permettre l'amélioration du coefficient de pénétration de véhicules automobiles dans l'air. Deflectors, the use of which is well known in the automotive industry, are intended to allow the improvement of the coefficient of penetration of motor vehicles in the air.
Bien que l'invention se situe dans ce contexte et poursuive la même finalité, elle permet de surcroît de résoudre un problème nouveau, qui est celui de la protection d'un mécanisme d'essuie-glace dont un véhicule automobile peut être doté, et qui, en position de repos, comprend au moins un essuie-glace adjacent à un bord dressé correspondant du pare-brise. Although the invention is situated in this context and pursues the same purpose, it also makes it possible to solve a new problem, which is that of the protection of a wiper mechanism with which a motor vehicle can be fitted, and which, in the rest position, comprises at least one wiper adjacent to a corresponding raised edge of the windscreen.
A cette fin, le déflecteur de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend un bandeau fixe et un rideau rigide et mobile, en ce que le bandeau est disposé à distance du pare-brise, le long de son bord supérieur, en ce que le rideau présente lui-même un bord supérieur, un bord inférieur et deux bords dressés, et en ce que le rideau est mobile entre une position escamotée dans laquelle ce rideau est au moins partiellement disposé entre le bandeau et le pare-brise, et une position déployée dans laquelle le bord inférieur de ce rideau dépasse du bandeau en direction du bord inférieur du pare-brise, vers lequel il converge. To this end, the deflector of the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that it comprises a fixed strip and a rigid and movable curtain, in that the strip is arranged at a distance from the windscreen, along its upper edge, in that the curtain itself has an upper edge, a lower edge and two erected edges, and in that the curtain is movable between a position retracted in which this curtain is at least partially disposed between the strip and the windshield, and a deployed position in which the lower edge of this curtain protrudes from the strip towards the lower edge of the windshield, towards which it converges.
Le rideau, en position déployée, converge de préférence vers le pare-brise. The curtain, in the deployed position, preferably converges towards the windshield.
Le bord inférieur du rideau peut ainsi être recouvert d'un joint déformable qui, en position déployée du rideau, est appliqué sur le pare-brise. The lower edge of the curtain can thus be covered with a deformable seal which, in the deployed position of the curtain, is applied to the windshield.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Les bords dressés du rideau sont très avantageusement espacés horizontalement des bords dressés du pare-brise de manière à n'interférer avec aucun essuie-glace disposé le long d'un bord dressé du parebrise. The erected edges of the curtain are very advantageously spaced horizontally from the erected edges of the windshield so as not to interfere with any wiper arranged along an erected edge of the windshield.
Le déflecteur de l'invention comporte par exemple une crémaillère solidaire du rideau et un pignon moteur engrenant avec la crémaillère pour déplacer le rideau entre sa position escamotée et sa position déployée, la crémaillère s'étendant de préférence parallèlement aux bords dressés du rideau. The deflector of the invention comprises for example a rack integral with the curtain and a drive pinion meshing with the rack to move the curtain between its retracted position and its deployed position, the rack preferably extending parallel to the erected edges of the curtain.
Pour son mouvement entre ses positions escamotée et déployée, le rideau peut être guidé par tout moyen sur le bandeau. For its movement between its retracted and deployed positions, the curtain can be guided by any means on the strip.
De préférence, le bandeau présente une section transversale en forme de coin, dont le sommet est tourné vers le bord inférieur du pare-brise. Preferably, the strip has a wedge-shaped cross section, the top of which faces the lower edge of the windshield.
Comme indiqué précédemment, le déflecteur de l'invention est particulièrement applicable à la protection sélective d'un mécanisme d'essuie-glace présentant, en position de repos, au moins un essuieglace adjacent à un bord dressé correspondant du parebrise. As indicated above, the deflector of the invention is particularly applicable to the selective protection of a wiper mechanism having, in the rest position, at least one wiper adjacent to a corresponding raised edge of the windshield.
D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquels : - la Figure 1 est une vue schématique en coupe d'un déflecteur conforme à l'invention, la coupe étant réalisée suivant un plan vertical médian du véhicule ; et - la Figure 2 est une vue schématique en perspective du déflecteur de la figure 1, illustré pour la position déployée du rideau. Other characteristics 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 drawings, in which: - Figure 1 is a schematic sectional view of 'A deflector according to the invention, the cut being made along a vertical median plane of the vehicle; and - Figure 2 is a schematic perspective view of the deflector of Figure 1, illustrated for the deployed position of the curtain.
Comme annoncé précédemment, l'invention concerne un déflecteur pour un véhicule automobile. As previously announced, the invention relates to a deflector for a motor vehicle.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
Ce déflecteur est plus particulièrement destiné à équiper le pare-brise 1 d'un véhicule automobile, ce pare-brise présentant de façon classique un bord supérieur 12, un bord inférieur 10 et deux bords dressés 11 (visible sur la figure 2). This deflector is more particularly intended to equip the windshield 1 of a motor vehicle, this windshield conventionally having an upper edge 12, a lower edge 10 and two raised edges 11 (visible in FIG. 2).
Le déflecteur de l'invention comprend principalement un bandeau fixe 2 et un rideau rigide et mobile 3. The deflector of the invention mainly comprises a fixed strip 2 and a rigid and movable curtain 3.
Comme le montre la figure 1, le bandeau 2, par exemple fixé sur les montants latéraux avant du véhicule, est disposé à distance du pare-brise 1, le long du bord supérieur 12 de ce dernier. As shown in FIG. 1, the strip 2, for example fixed on the front lateral uprights of the vehicle, is arranged at a distance from the windscreen 1, along the upper edge 12 of the latter.
Ce bandeau 2 présente une section transversale en forme de coin, dont le sommet 20 est tourné vers le bord inférieur 10 du pare-brise 1. This strip 2 has a wedge-shaped cross section, the top 20 of which faces the lower edge 10 of the windshield 1.
Le rideau 3 présente lui-même un bord supérieur 32, un bord inférieur 30 et deux bords dressés 31. The curtain 3 itself has an upper edge 32, a lower edge 30 and two raised edges 31.
Ce rideau 3 est monté mobile, par rapport au bandeau 1, entre une position escamotée et une position déployée. This curtain 3 is mounted movable, relative to the strip 1, between a retracted position and a deployed position.
Dans sa position escamotée, illustrée en traits pleins sur la figure 1, le rideau 3 est au moins partiellement disposé entre le bandeau 2 et le pare-brise 1. In its retracted position, illustrated in solid lines in FIG. 1, the curtain 3 is at least partially disposed between the strip 2 and the windshield 1.
En revanche, dans la position déployée du rideau 3, illustrée en pointillés sur la figure 1, le bord inférieur 30 de ce rideau 3 dépasse nettement du bandeau 2 en direction du bord inférieur 10 du pare-brise 1. On the other hand, in the deployed position of the curtain 3, illustrated in dotted lines in FIG. 1, the lower edge 30 of this curtain 3 clearly protrudes from the strip 2 in the direction of the lower edge 10 of the windshield 1.
Comme le montre également la figure 1, le rideau 3, en position déployée, converge vers le pare-brise 1. En d'autres termes, la distance, prise dans un plan vertical, entre un point du rideau et le pare-brise, est d'autant plus faible que ce point est éloigné du bandeau 2. As also shown in FIG. 1, the curtain 3, in the deployed position, converges towards the windshield 1. In other words, the distance, taken in a vertical plane, between a point of the curtain and the windshield, is all the weaker as this point is far from the strip 2.
Le bord inférieur 30 du rideau 3 est recouvert d'un joint déformable 4 qui, en position déployée du rideau, The lower edge 30 of the curtain 3 is covered with a deformable seal 4 which, in the deployed position of the curtain,
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Ce joint, de forme aérodynamique, s'applique de préférence de façon étanche sur le pare-brise et permet ainsi d'éviter que l'air ne s'engouffre entre le parebrise et le rideau 3. This aerodynamically shaped seal is preferably applied in a leaktight manner to the windshield and thus makes it possible to prevent air from rushing between the windshield and the curtain 3.
Pour déplacer le rideau 3 entre sa position escamotée et sa position déployée, le déflecteur de l'invention comprend une crémaillère 51 et un pignon moteur 52. To move the curtain 3 between its retracted position and its deployed position, the deflector of the invention comprises a rack 51 and a motor pinion 52.
La crémaillère 51 est solidaire du rideau 3 et s'étend parallèlement aux bords dressés 31 de ce rideau 3. The rack 51 is integral with the curtain 3 and extends parallel to the raised edges 31 of this curtain 3.
Le pignon moteur 52 engrène avec la crémaillère 51 et est mû par un moteur électrique (non représenté). The driving pinion 52 meshes with the rack 51 and is driven by an electric motor (not shown).
Pour son déplacement entre sa position escamotée et sa position déployée, le rideau 3 est guidé par tout moyen approprié sur le bandeau 1. For its movement between its retracted position and its deployed position, the curtain 3 is guided by any appropriate means on the strip 1.
L'invention est particulièrement applicable aux véhicules automobiles équipés d'un mécanisme d'essuieglace à guidage linéaire. The invention is particularly applicable to motor vehicles fitted with a wiper mechanism with linear guidance.
Comme le montre la figure 2, un tel mécanisme comprend un ou deux essuie-glaces 6, dont chacun est disposé, en position de repos, à proximité immédiate d'un bord dressé 11 correspondant du pare-brise 1. Les moteurs électriques des mécanismes d'essuie-glaces sont par exemple logés dans un carter 7. As shown in FIG. 2, such a mechanism comprises one or two wipers 6, each of which is arranged, in the rest position, in the immediate vicinity of a corresponding raised edge 11 of the windshield 1. The electric motors of the mechanisms wipers are for example housed in a casing 7.
En fonctionnement, chacun de ces essuie-glaces se déplace parallèlement à lui-même grâce à des organes de guidage disposés entre le bandeau 2 et le pare-brise 1. In operation, each of these wipers moves parallel to itself thanks to guide members arranged between the strip 2 and the windshield 1.
Dans ces conditions, les bords dressés 31 du rideau 3 sont de préférence espacés horizontalement des bords dressés 11 du pare-brise 1, de manière que le rideau 3, dans sa position déployée, s'intercale entre les essuieglaces 6 dans leur position de repos. Under these conditions, the raised edges 31 of the curtain 3 are preferably spaced horizontally from the raised edges 11 of the windshield 1, so that the curtain 3, in its deployed position, is inserted between the wipers 6 in their rest position. .
Grâce à l'agencement de l'invention, non seulement le coefficient de pénétration du véhicule dans l'air est amélioré par l'abaissement du rideau en position Thanks to the arrangement of the invention, not only the coefficient of penetration of the vehicle in the air is improved by lowering the curtain in position
