Description
Vitraqe destiné à être adapté sur une carrosserie de véhiculeVitraqe intended to be adapted to a vehicle body
L'invention se rapporte à un vitrage destiné à être adapté sur une carrosserie de véhicule. The invention relates to a glazing intended to be adapted to a vehicle body.
Les vitrages équipant les véhicules ont aujourd'hui tendance à augmenter en surface, ainsi certains vitrages ont une partie formant pare-brise et une autre appartenant au pavillon du véhicule. De plus, la place accordée aux zones io structurelles tend à se réduire au strict nécessaire afin de ne pas géner la visibilité du conducteur. The windows fitted to vehicles today tend to increase in surface, so some windows have a part forming windshield and another belonging to the pavilion of the vehicle. In addition, the place accorded to the structural zones tends to be reduced to what is strictly necessary so as not to impair the visibility of the driver.
Néanmoins pour ce type de vitrage, afin de satisfaire les prestations de tenue en choc et de rigidité de la structure du véhicule, des traverses sont nécessaires. Ainsi, ces véhicules possèdent notamment une traverse orientée transversalement au véhicule, disposée entre la zone avant du pavillon et la zone arrière du pare-brise. La traverse est réalisée en tôle emboutie, la zone du vitrage située, entre la partie formant parebrise et la partie appartenant au pavillon du véhicule, est alors collée sur cette traverse. However, for this type of glazing, in order to satisfy the benefits of shock resistance and stiffness of the vehicle structure, sleepers are necessary. Thus, these vehicles have in particular a cross-beam oriented transversely to the vehicle, disposed between the front zone of the roof and the rear area of the windshield. The cross is made of pressed sheet metal, the glazing area between the windshield portion and the part belonging to the vehicle roof, is then glued to this cross.
Toutefois, la traverse présente un certain encombrement dû à son volume, aux zones permettant le collage du vitrage... De plus pour des raisons esthétiques, la traverse doit être recouverte d'un garnissage. However, the crossbar has a certain size due to its volume, the areas for gluing the glazing ... Moreover for aesthetic reasons, the cross must be covered with a lining.
Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
A cette fin, le vitrage selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il intègre un élément intermédiaire formant traverse destiné à renforcer ladite carrosserie. To this end, the glazing according to the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that it incorporates an intermediate element forming a cross member for reinforcing said bodywork.
Par ailleurs, l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes: - le vitrage comprend au moins une première feuille et une seconde feuille reliées l'une à l'autre par une couche adhésive intercalaire, l'élément intermédiaire est disposé entre les deux feuilles, - l'élément intermédiaire a une épaisseur de 0,1 à 1,5 mm, l'élément intermédiaire est disposé à proximité de l'une des feuilles du vitrage, - une couche adhésive est interposée entre chacune des faces de l'élément intermédiaire et les dites première et deuxième feuilles, l'élément intermédiaire comprend des éléments métalliques et/ou des charges de renforcement telles que des fibres de verre, des fibres organiques, notamment des fibres de carbone, - les charges de renforcement sont entourées d'un polymère thermodurcissable, telle qu'une résine, - la première et la deuxième feuille sont réalisées en verre, et la couche adhésive intercalaire est 25 réalisée en polyvinylbutyral, - la carrosserie possède une paire de montants latéraux et une paire d'arcs de pavillon, les extrémités latérales dudit élément intermédiaire viennent se positionner à proximité de la zone de jonction des montants latéraux et des arcs de pavillon, - le vitrage comprend deux parties, une première partie formant pare-brise et une deuxième partie appartenant au pavillon du véhicule, l'élément intermédiaire est situé dans la zone de jonction de ces deux parties. Furthermore, the invention may comprise one or more of the following features: the glazing comprises at least a first sheet and a second sheet connected to one another by an interlayer adhesive layer, the intermediate element is arranged between the two sheets, the intermediate element has a thickness of 0.1 to 1.5 mm, the intermediate element is placed close to one of the sheets of the glazing, an adhesive layer is interposed between each of the faces. of the intermediate element and said first and second sheets, the intermediate element comprises metal elements and / or reinforcing fillers such as glass fibers, organic fibers, in particular carbon fibers, reinforcing fillers, are surrounded by a thermosetting polymer, such as a resin, the first and second sheets are made of glass, and the interlayer adhesive layer is made of polyvinyl butyral, the bodywork has a pair of lateral uprights and a pair of roof arches, the lateral ends of said intermediate element are positioned close to the junction zone of the lateral uprights and roof arches, the glazing comprises two parts, a first part forming windshield and a second part belonging to the vehicle roof, the intermediate element is located in the junction zone of these two parts.
D'autres particularités et avantages apparaîtront à la lecture de la description ci-après faite en référence aux figures dans lesquelles: -la figure 1 représente une vue schématique en io perspective d'une carrosserie de véhicule automobile équipée d'un vitrage conforme à l'invention, - la figure 2 représente une vue schématique en coupe du vitrage de l'invention. Other particularities and advantages will appear on reading the following description made with reference to the figures in which: FIG. 1 represents a diagrammatic perspective view of a motor vehicle bodywork equipped with a glazing unit in accordance with FIG. FIG. 2 represents a schematic sectional view of the glazing unit of the invention.
Comme le montre la figure 1, la carrosserie de véhicule comprend deux montants latéraux 11, aussi appelés montants de baie, deux arcs de pavillon 13 et un pavillon 12. As shown in FIG. 1, the vehicle bodywork comprises two lateral uprights 11, also called bay struts, two roof arches 13 and a roof 12.
De façon traditionnelle, les montants de baie 11, encadrent et soutiennent le pare-brise 25 du véhicule; les arcs de pavillon 13 qui s'étendent longitudinalement vers l'arrière du véhicule supportent le pavillon 12. Ces arcs de pavillon 13 sont reliés à leur extrémité opposée au pavillon avant par une traverse de pavillon arrière 14, de sorte que l'ensemble formé par le pavillon 12, par les arcs de pavillon 13 et par la traverse arrière de pavillon 14 possède sensiblement la forme d'un parallélogramme. Traditionally, the rack amounts 11, frame and support the windshield 25 of the vehicle; the roof arches 13 which extend longitudinally towards the rear of the vehicle support the roof 12. These roof arches 13 are connected at their opposite end to the front roof by a rear roof crossbar 14, so that the assembly formed by the flag 12, the roof arches 13 and the rear roof cross member 14 has substantially the shape of a parallelogram.
La carrosserie du véhicule est équipée d'un vitrage, dont une partie forme le pare-brise 25, l'autre partie 26 forme une portion du pavillon 12. Ce vitrage 20 est réalisé en une seule pièce. Ces deux parties possèdent ainsi des angles d'inclinaison différents. The body of the vehicle is equipped with a glazing, part of which forms the windshield 25, the other part 26 forms a portion of the roof 12. This glazing 20 is made in one piece. These two parts thus have different angles of inclination.
La partie formant le pare-brise 25 est fixée sur les montants de baie 11, tandis que la partie 26 formant une portion du pavillon 12 est fixée sur la partie avant des arcs de pavillon 13. La partie arrière arcs de pavillon 13 reçoit la seconde partie du pavillon 12, réalisée de façon classique en acier, en aluminium ou en matériau composite. The portion forming the windshield 25 is fixed on the uprights 11, while the portion 26 forming a portion of the roof 12 is fixed on the front part of the roof arches 13. The rear part roof arches 13 receives the second part of the roof 12, made conventionally of steel, aluminum or composite material.
Des moyens de fixation assurent le maintien du vitrage 20 sur les arcs de pavillon 13 et sur les montants de baie 11. Ces moyens peuvent être mécaniques, ou constitués d'un matériau io adhésif tel qu'un mastic ou une colle. Fixing means ensure the maintenance of the glazing 20 on the roof arches 13 and on the uprights 11. This means may be mechanical, or consist of an adhesive material such as mastic or glue.
Le vitrage 20 est constitué de deux feuilles de verre 21, 22 reliées l'une à l'autre par une couche adhésive 23 de polyvinylbutyral, aussi appelé PVB, possédant une épaisseur d'environ 1 mm. The glazing 20 consists of two glass sheets 21, 22 connected to one another by an adhesive layer 23 of polyvinyl butyral, also called PVB, having a thickness of about 1 mm.
Selon l'invention, le vitrage comprend une traverse 24 composite intégrée au vitrage 20. Cette traverse 24 est orientée transversalement au véhicule, dans la zone avant du pavillon 12. Les deux extrémités latérales de la traverse 24 viennent se positionner à proximité de la zone de jonction 15 des montants de baie 11 et des arcs de pavillon 13. Ainsi, la traverse 24 se trouve également dans la zone de jonction des deux parties 25, 26 décrites précédemment formant le vitrage 20. According to the invention, the glazing comprises a composite crossmember 24 integrated with the glazing 20. This crossmember 24 is oriented transversely to the vehicle, in the front zone of the roof 12. The two lateral ends of the crossmember 24 are positioned near the zone joining the rack posts 11 and roof arches 13. Thus, the crossbar 24 is also in the junction zone of the two parts 25, 26 previously described forming the glazing 20.
Plus particulièrement, la traverse 24 est constituée d'une résine du type époxy, phénolique ou polyester insaturé renforcée de fibres de verre. La traverse possède une épaisseur de 0,1 à 1,5 mm. More particularly, the crossbar 24 is made of a resin of the epoxy, phenolic or unsaturated polyester fiberglass reinforced type. The cross member has a thickness of 0.1 to 1.5 mm.
La traverse 24 est comprise entre les deux feuilles de verre 21, 22 du vitrage; elle se trouve, par exemple, noyée dans la couche 23 de PVB (voir figure 2) ou située à proximité de l'une des feuilles 21, 22 du vitrage 20. The crossbar 24 is between the two glass sheets 21, 22 of the glazing; it is, for example, embedded in the layer 23 of PVB (see Figure 2) or located near one of the sheets 21, 22 of the glazing 20.
Ainsi, une telle traverse 24 intégrée au vitrage permet de supprimer la traverse métallique traditionnellement utilisée. Les bénéfices obtenus sont notamment une optimisation de la largeur de la traverse ainsi créée et une possible décoration de la zone de renfort grâce à l'aspect technique des fibres. La traverse intégrée au vitrage gène ainsi au minimum le conducteur. Thus, such a cross member 24 integrated glazing allows to remove the metal crossbar traditionally used. The benefits obtained include an optimization of the width of the crossbar thus created and a possible decoration of the reinforcement zone thanks to the technical aspect of the fibers. The crossbar integrated into the glazing gene and at a minimum the driver.
L'intégration de la traverse 24 composite dans le vitrage 20, peut notamment se faire avant le passage en autoclave du io vitrage 20 feuilleté à un stade où les différentes feuilles 21, 22 et la couche adhésive 23 sont préparées en vue de leur assemblage. Ainsi, lors de cette étape, la traverse 24 est placée dans la couche adhésive 23 ou à l'interface de l'une des feuilles 21, 22 et de la couche adhésive 23, comme vus précédemment. Puis, le vitrage 20 est passé en autoclave afin de permettre l'assemblage des différents éléments 21, 22, 23, 24 et leur solidarisation et aussi afin de figer la géométrie du vitrage 20. The integration of the composite crossmember into the glazing 20 may in particular be carried out before the laminated glazing is autoclaved at a stage where the various sheets 21, 22 and the adhesive layer 23 are prepared for their assembly. Thus, during this step, the cross member 24 is placed in the adhesive layer 23 or at the interface of one of the sheets 21, 22 and the adhesive layer 23, as seen above. Then, the glazing 20 is autoclaved in order to allow the assembly of the various elements 21, 22, 23, 24 and their joining together and also to freeze the geometry of the glazing 20.
Le passage en autoclave permet la polymérisation de la résine thermodurcissable, ce qui assure la robustesse de la traverse 24. The passage in an autoclave allows the polymerization of the thermosetting resin, which ensures the robustness of the crossbar 24.
L'invention s'applique également à une traverse intégrée au vitrage réalisée en éléments métalliques ou en fibres organiques, notamment en fibres de carbone. Dans ce dernier cas, les fibres organiques sont également enrobées de résine. Tout autre fibre permettant de rigidifier la structure du véhicule peut être envisagée. The invention also applies to an integrated transom glazing made of metal elements or organic fibers, especially carbon fibers. In the latter case, the organic fibers are also coated with resin. Any other fiber that makes it possible to stiffen the structure of the vehicle can be envisaged.
De même, le vitrage peut être composé de feuilles de polymères tels que du polyméthacrylate de méthyle (PMMA) ou du polycarbonate (PC), l'adhésif utilisé est alors du polyuréthanne (PU). Similarly, the glazing may be composed of polymer sheets such as polymethyl methacrylate (PMMA) or polycarbonate (PC), the adhesive used is then polyurethane (PU).
