Description

PARE-BRISE DONT AU MOINS LA PARTIE INTERIEURE EST CONSTITUEE PAR UNE PAROI EN MATIERE PLASTIQUE TRANSPARENTE  WINDSHIELDS OF WHICH AT LEAST THE INNER PART IS CONSISTED OF A TRANSPARENT PLASTIC WALL
La présente invention concerne un pare-brise dont au moins la partie intérieure est constituée par une paroi en matière plastique transparente. The present invention relates to a windshield at least the inner portion is constituted by a transparent plastic wall.
L'invention concerne également un véhicule automobile équipé d'un tel pare- brise.  The invention also relates to a motor vehicle equipped with such a windshield.
La figure 1 est une vue en coupe longitudinale partielle montrant un pare- brise fixé sur la baie d'un véhicule automobile ainsi qu'une grille d'auvent fixée à ce pare-brise.  Figure 1 is a partial longitudinal sectional view showing a windshield attached to the bay of a motor vehicle and an awning grid attached to the windshield.
Actuellement, selon les normes en vigueur, le pare-brise 1 est en verre feuilleté et est fixé sur la baie 2 du véhicule grâce à un cordon de colle 3.  Currently, according to the standards in force, the windshield 1 is laminated glass and is fixed to the bay 2 of the vehicle with a bead of glue 3.
La référence 4 désigne une grille d'auvent qui est fixée au bord inférieur 1 a du pare-brise 1 au moyen d'un joint 5 qui est chaussé sur le bord 1 a du pare-brise 1 ou collé à ce bord 1 a.  Reference 4 designates an awning grid which is attached to the lower edge 1a of the windshield 1 by means of a gasket 5 which is shod on the edge 1a of the windshield 1 or glued to this edge 1a.
Ce joint 5 présente une gorge 6 présentant deux lèvres souples 7 permettant la fixation par encliquetage entre celles-ci d'une partie saillante 8 de la grille d'auvent 4.  This seal 5 has a groove 6 having two flexible lips 7 allowing attachment by snapping between them of a projecting portion 8 of the awning grid 4.
La face inférieure du joint 5 comporte des protubérances 9 prenant appui sur la traverse inférieure de la baie 2.  The underside of the gasket 5 has protuberances 9 bearing on the bottom rail of the bay 2.
Grâce à ces protubérances 9, le joint 5 permet de régler l'épaisseur du cordon de colle 3.  Thanks to these protuberances 9, the seal 5 makes it possible to adjust the thickness of the adhesive bead 3.
La fabrication et le montage du joint 5 présentent l'inconvénient d'être coûteux, car ce joint est une pièce distincte du pare-brise et de la grille d'auvent.  The manufacture and assembly of the gasket 5 have the disadvantage of being expensive, because this gasket is a separate part of the windshield and the awning grid.
Le but de la présente invention est de remédier à cet inconvénient.  The object of the present invention is to overcome this disadvantage.
Ce but est atteint, selon l'invention, grâce à un pare-brise dont au moins la partie intérieure est constituée par une paroi en matière plastique transparente, caractérisé en ce que l'un des bords de cette paroi comporte une partie moulée d'une seule pièce avec ladite paroi, qui présente des moyens permettant la fixation par encliquetage d'une pièce fonctionnelle distincte du pare-brise.  This object is achieved, according to the invention, thanks to a windshield whose at least the inner part is constituted by a transparent plastic wall, characterized in that one of the edges of this wall comprises a molded part of a single piece with said wall, which has means for snap fastening of a separate functional part of the windshield.
Le joint chaussé ou collé sur le bord du pare-brise est ainsi, selon l'invention, remplacé par une partie moulée d'une seule pièce avec la paroi en matière plastique qui constitue une partie ou la totalité du pare-brise. Sur cette partie moulée peut être fixée par encliquetage une pièce fonctionnelle, telle qu'une grille d'auvent. The seal shod or glued on the edge of the windshield is thus, according to the invention, replaced by a molded part in one piece with the plastic wall which constitutes a part or the whole of the windshield. On this molded part can be snap-fastened a functional part, such as a cowl grille.
L'invention permet ainsi de diminuer les coûts de fabrication et de montage évoqués plus haut.  The invention thus makes it possible to reduce the manufacturing and assembly costs mentioned above.
Dans une version préférée de l'invention, la partie extérieure du pare-brise est constituée par une feuille en verre qui est collée sur ladite paroi en matière plastique transparente.  In a preferred version of the invention, the outer portion of the windshield is constituted by a glass sheet which is bonded to said transparent plastic wall.
Cependant, le pare-brise peut être entièrement en matière plastique transparente.  However, the windshield may be entirely of transparent plastic.
Dans cette version, ladite partie moulée est de préférence moulée d'une seule pièce avec le bord de ladite paroi en matière plastique transparente destiné à être collé sur la traverse inférieure de la baie du pare-brise.  In this version, said molded part is preferably molded in one piece with the edge of said transparent plastic wall to be glued to the lower rail of the windshield bay.
De préférence également, ladite partie comporte une gorge de section transversale en U dont les deux ailes latérales sont munies chacune d'une lèvre souple permettant la fixation par encliquetage d'une grille d'auvent constituant ladite pièce fonctionnelle distincte du pare-brise.  Also preferably, said portion comprises a U-shaped cross-section groove, the two lateral wings of which are each provided with a flexible lip allowing snap-fastening of an awning grid constituting said functional part distinct from the windshield.
Selon une particularité avantageuse de l'invention, les deux ailes latérales de ladite gorge font saillie par rapport à la face extérieure de ladite paroi en matière plastique transparente sur laquelle est collée ladite feuille en verre.  According to an advantageous feature of the invention, the two lateral wings of said groove protrude from the outer face of said transparent plastic wall on which said glass sheet is bonded.
Dans un mode de réalisation avantageux de l'invention, ladite partie comporte une face faisant saillie par rapport à la face intérieure de ladite paroi en matière plastique transparente, cette face étant destinée à prendre appui sur la traverse inférieure de la baie du pare-brise.  In an advantageous embodiment of the invention, said part comprises a surface projecting from the inside of said transparent plastic wall, this face being intended to bear on the lower cross member of the windshield bay. .
Cette face permet ainsi de régler la distance entre le pare-brise et la baie du véhicule et par conséquent l'épaisseur du cordon de colle.  This face thus adjusts the distance between the windshield and the vehicle bay and therefore the thickness of the adhesive bead.
Dans un mode de réalisation préféré, ladite paroi est en matière plastique transparente dure et ladite partie comprend plusieurs zones en matière plastique souple obtenues par co-injection.  In a preferred embodiment, said wall is made of hard transparent plastics material and said part comprises a plurality of soft plastic zones obtained by co-injection.
Ces zones souples par exemple en élastomère permettent à ces zones de se déformer et donc de présenter des fonctions avantageuses par rapport aux surfaces destinées à venir en contact avec ces zones.  These flexible zones, for example made of elastomer, allow these zones to deform and thus to have advantageous functions with respect to the surfaces intended to come into contact with these zones.
Selon une autre particularité avantageuse, la face extérieure de la paroi en matière plastique transparente est recouverte par une couche résistive électriquement conductrice reliée à un fil conducteur noyé dans la partie moulée destiné à être connecté à une source d'alimentation électrique. According to another advantageous feature, the outer face of the transparent plastic wall is covered by a resistive layer electrically conductive connected to a conductive wire embedded in the molded portion to be connected to a power source.
Cette couche lorsqu'elle est alimentée électriquement peut ainsi chauffer le pare-brise et dégivrer celui-ci.  This layer when electrically powered can heat the windshield and defrost it.
Selon un autre aspect, l'invention concerne également un véhicule automobile équipé d'un pare-brise selon l'invention.  According to another aspect, the invention also relates to a motor vehicle equipped with a windshield according to the invention.
D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après.  Other features and advantages of the invention will become apparent throughout the description below.

- la figure 5 est une vue analogue à la figure 4, à échelle agrandie, montrant d'autres particularités de l'invention.  - Figure 5 is a view similar to Figure 4, on an enlarged scale, showing other features of the invention.
La figure 2 représente la partie inférieure 1 1 d'un pare-brise selon l'invention. Cette partie inférieure 1 1 est constituée par une paroi en matière plastique transparente, telle que le polycarbonate ou le polyméthacrylate de méthyle (PMMA).  FIG. 2 represents the lower part 11 of a windshield according to the invention. This lower part 11 is constituted by a transparent plastic wall, such as polycarbonate or polymethylmethacrylate (PMMA).
Conformément à l'invention, l'un 1 1 a des bords de cette paroi 1 1 comporte une partie 12 moulée d'une seule pièce avec cette paroi.  According to the invention, one 1 1 has edges of this wall January 1 comprises a portion 12 molded in one piece with this wall.
Cette partie 12 présente des moyens qui seront détaillés plus loin permettant la fixation par encliquetage d'une pièce fonctionnelle 19 distincte du pare-brise.  This part 12 has means which will be detailed later allowing snap attachment of a functional part 19 separate from the windshield.
Comme montré sur la figure 2, la partie extérieure 13 du pare-brise est constituée par une feuille en verre qui est collée sur la paroi 1 1 en matière plastique transparente par exemple grâce à une couche 14 de résine polyuréthane.  As shown in Figure 2, the outer portion 13 of the windshield is constituted by a glass sheet which is bonded to the wall 1 1 of transparent plastic material for example by a layer 14 of polyurethane resin.
Le pare-brise représenté sur la figure 3 est communément appelé « pare- brise hybride » en raison de sa constitution en verre et en matière plastique. La figure 4 représente le pare-brise tel que montré sur la figure 3, fixé sur la baie d'un véhicule. The windshield shown in Figure 3 is commonly called "hybrid windshield" because of its constitution in glass and plastic. Figure 4 shows the windshield as shown in Figure 3, attached to the bay of a vehicle.
Sur cette figure 4, la référence 15 désigne la traverse inférieure de la baie du véhicule.  In this figure 4, the reference 15 designates the lower rail of the vehicle bay.
Le pare-brise est fixé sur la traverse 15 grâce à un cordon de colle 16 qui est comprimé entre la paroi inférieure 1 1 en matière plastique transparente et la traverse 15.  The windshield is fixed on the crosspiece 15 by means of a bead of glue 16 which is compressed between the lower wall 1 1 of transparent plastic material and the crosspiece 15.
On voit sur les figures 2, 3 et 4, que la partie 12 est moulée d'une seule pièce avec le bord 1 1 a de la paroi 1 1 en matière plastique transparente destiné à être collé sur la traverse inférieure 15 de la baie du pare-brise.  FIGS. 2, 3 and 4 show that the part 12 is molded in one piece with the edge 11a of the wall 11 of transparent plastic material intended to be bonded to the lower crossmember 15 of the windshield.
Cette partie 12 comporte une gorge 17 de section transversale en U dont les deux ailes latérales 17a, 17b sont munies chacune d'une lèvre souple 18a, 18b permettant la fixation par encliquetage d'une pièce fonctionnelle distincte du pare- brise, telle que la grille d'auvent 19 représentée sur la figure 4.  This portion 12 comprises a groove 17 of U cross section whose two lateral wings 17a, 17b are each provided with a flexible lip 18a, 18b for snap fastening of a separate functional part of the windshield, such as the Louvre grille 19 shown in Figure 4.
Les figures 2 à 4 montrent que les deux ailes latérales 17a, 17b de la gorge Figures 2 to 4 show that the two lateral wings 17a, 17b of the throat
17 font saillie par rapport à la face extérieure 1 1 b de la paroi 1 1 en matière plastique transparente sur laquelle est collée la feuille en verre 13. 17 protrude from the outer face 1 1 b of the wall 1 1 of transparent plastic material on which is glued the glass sheet 13.
La distance entre le sommet des ailes 17a, 17b est sensiblement égale à l'épaisseur de la feuille en verre 13.  The distance between the top of the wings 17a, 17b is substantially equal to the thickness of the glass sheet 13.
Par ailleurs, la partie 12 comporte une face 20 faisant saillie par rapport à la face intérieure 1 1 c de la paroi 1 1 en matière plastique transparente.  Furthermore, the portion 12 has a face 20 projecting from the inner face 1 1 c of the wall 1 1 transparent plastic material.
Cette face 20 comporte deux nervures 20a, 20b destinées à prendre appui sur la traverse inférieure 15 de la baie du pare-brise, comme montré sur la figure 4.  This face 20 comprises two ribs 20a, 20b intended to bear on the lower cross member 15 of the windshield bay, as shown in FIG. 4.
La paroi 1 1 est en matière plastique transparente dure, telle que le polycarbonate ou le PMMA.  The wall 1 1 is made of hard transparent plastic, such as polycarbonate or PMMA.
Cependant, cette paroi 1 1 peut comprendre plusieurs zones en matière plastique souple obtenues par co-injection.  However, this wall 1 1 may comprise several areas of flexible plastic material obtained by co-injection.
Ces zones sont hachurées sur la vue agrandie de la figure 5.  These areas are hatched in the enlarged view of Figure 5.
Ces zones comprennent les deux lèvres souples 18a, 18b, les deux nervures These zones comprise the two flexible lips 18a, 18b, the two ribs
20a, 20b destinées à venir en appui sur la traverse inférieure 15 de la baie du pare-brise et la face de l'aile 17a de la gorge en U 17 adjacente à la feuille en verre 13 du pare-brise. Ces zones souples peuvent être en élastomère. 20a, 20b intended to bear against the lower cross member 15 of the windshield bay and the side of the wing 17a of the U-shaped groove 17 adjacent to the glass sheet 13 of the windshield. These soft areas may be elastomeric.
Grâce à leur souplesse, ces zones peuvent se déformer et remplir ainsi des fonctions techniques avantageuses.  Thanks to their flexibility, these zones can deform and thus fulfill advantageous technical functions.
Ainsi, la souplesse des lèvres 18a et 18b de la partie 12 permet à celles-ci de se déformer lors de l'engagement de l'élément de fixation 21 porté par la grille d'auvent 19 dans la gorge 17 de cette partie et de l'encliquetage de cet élément 21 entre les deux lèvres.  Thus, the flexibility of the lips 18a and 18b of the portion 12 allows them to deform during the engagement of the fastener 21 carried by the awning grid 19 in the groove 17 of this part and the snap of this element 21 between the two lips.
La souplesse de la zone adjacente à la feuille de verre 13 permet de protéger celle-ci contre les chocs.  The flexibility of the area adjacent to the glass sheet 13 protects it from shocks.
De plus, la souplesse des nervures 20a, 20b permet de filtrer les vibrations qui sont transmises au pare-brise.  In addition, the flexibility of the ribs 20a, 20b can filter the vibrations that are transmitted to the windshield.
En outre, la distance comprise entre le sommet des nervures 20a, 20b et la face intérieure 1 1 c de la paroi 1 1 permet de régler l'écrasement du cordon de colle 16, c'est-à-dire la distance comprise entre la face 1 1 c et la traverse 15.  In addition, the distance between the apex of the ribs 20a, 20b and the inner face 1 1c of the wall 1 1 makes it possible to adjust the crushing of the adhesive bead 16, that is to say the distance between the face 1 1 c and the cross 15.
Dans l'exemple représenté sur la figure 5, la face extérieure 1 1 b de la paroi In the example shown in FIG. 5, the outside face 1 1 b of the wall
1 1 en matière plastique transparente est recouverte par une couche résistive électriquement conductrice 22 reliée à un fil conducteur 23 noyé dans la partie moulée 12 de la paroi 1 1 destiné à être connecté à une source d'alimentation électrique 24. 1 1 transparent plastic is covered by an electrically conductive resistive layer 22 connected to a conductor wire 23 embedded in the molded portion 12 of the wall 1 1 intended to be connected to a power supply 24.
Cette couche conductrice 22 est recouverte par la couche de colle 14 appliquée sous la feuille de verre 13.  This conductive layer 22 is covered by the layer of adhesive 14 applied under the glass sheet 13.
Lorsque cette couche conductrice 23 est alimentée électriquement, elle chauffe le pare-brise, ce qui permet de le dégivrer.  When this conductive layer 23 is electrically powered, it heats the windshield, which allows defrosting.
L'invention peut également s'appliquer à un pare-brise entièrement en matière plastique transparente.  The invention can also be applied to a windshield made entirely of transparent plastic.
Dans ce cas, la paroi 1 1 n'est pas recouverte par une feuille de verre, mais simplement recouverte par une couche de vernis de protection à l'égard des rayures.  In this case, the wall January 1 is not covered by a sheet of glass, but simply covered by a layer of protective varnish against scratches.
Bien entendu, la partie 12 du pare-brise pourrait servir à fixer des pièces fonctionnelles autres qu'une grille d'auvent.  Of course, the portion 12 of the windshield could be used to attach functional parts other than a canopy grille.
