Description
Habillage intérieur de véhicule et procédé de fabrication d'un tel habillage. La présente invention concerne un habillage intérieur de véhicule, du type comprenant une armature rigide et une garniture souple recouvrant l'armature. Un habillage de ce type est utilisable dans tout type de véhicule, et notamment dans les véhicules automobiles, les trains ou les avions. Les constructeurs de véhicules, notamment de véhicules automobiles, souhaitent disposer d'habillages intérieurs possédant un aspect visuel et un toucher conférant une impression de bonne qualité pour les utilisateurs, notamment concernant l'assemblage et l'ajustage des pièces. Vehicle interior trim and method of making such a trim. The present invention relates to a vehicle interior lining, of the type comprising a rigid frame and a flexible lining covering the frame. A dressing of this type can be used in any type of vehicle, and in particular in motor vehicles, trains or aircraft. Manufacturers of vehicles, especially motor vehicles, wish to have interior cladding having a visual appearance and a touch giving a good quality impression for users, particularly concerning the assembly and adjustment of parts.
Pour ce faire, il est possible de prévoir un habillage intérieur comprenant une armature rigide recouverte par un revêtement bicouche comprenant une garniture souple et un textile. La garniture confère de la souplesse au toucher, et le textile améliore la qualité visuelle et le toucher superficiel de l'habillage intérieur. Néanmoins, la fixation du revêtement bicouche sur l'armature nécessite de tendre le revêtement pour éviter la formation de bourrelets inesthétiques dans le revêtement. De ce fait, toutes les formes d'habillage intérieur ne sont pas réalisables avec une qualité suffisante, et cette opération est délicate à réaliser. En outre, l'accostage de l'habillage intérieur avec une autre pièce du véhicule risque de former des bourrelets dans le revêtement. To do this, it is possible to provide an interior lining comprising a rigid frame covered by a bilayer coating comprising a flexible liner and a textile. The lining provides softness to the touch, and the textile improves the visual quality and surface feel of the interior trim. Nevertheless, the fixation of the bilayer coating on the reinforcement requires tensioning the coating to avoid the formation of unsightly beads in the coating. As a result, not all forms of interior trim are feasible with sufficient quality, and this operation is difficult to achieve. In addition, the docking of the interior trim with another part of the vehicle may form beads in the coating.
Un but de l'invention est de fournir un habillage intérieur de véhicule conférant une impression de bonne qualité perçue, qui soit facile à fabriquer, et offrant une plus grande liberté de style. A cet effet, l'invention propose un habillage intérieur de véhicule du type précité, dans lequel la garniture est surmoulée sur l'armature et floquée avec des fibres. Selon d'autres modes de réalisation, l'habillage intérieur comprend une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou suivant toutes les combinaisons techniquement possibles : - la garniture est réalisée en mousse ; - la garniture est réalisée en gel ; - l'épaisseur de la garniture est égale ou supérieure à 1 mm ; - la garniture comprend des régions plus épaisses ; - les fibres de flocage sont des fibres textiles, notamment des fibres de polyamide ou de polypropylène ; et - l'épaisseur du flocage est égale ou supérieure à 0.1 mm. L'invention concerne également un véhicule automobile comprenant un habillage intérieur tel que défini ci-dessus. L'invention concerne encore un procédé de fabrication d'un habillage intérieur tel que défini ci-dessus, dans lequel on surmoule la garniture sur le support par moulage par injection, puis on floque la garniture avec les fibres. L'invention et ses avantages seront mieux compris à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés, sur lesquels : - la Figure 1 est une vue en coupe d'un habillage intérieur de véhicule automobile ; - les Figures 2 à 4 sont des vues analogues à celle de la Figure 1, illustrant des étapes d'un procédé de fabrication de l'habillage intérieur de la Figure 1 ; et - les Figures 5 et 6 sont des vues analogues à celle de la Figure 1 et illustrant des modes de réalisation particuliers. Tel que représenté sur la Figure 1, l'habillage 2 est destiné à être fixé à l'intérieur d'un véhicule automobile pour habiller par exemple un accoudoir, un panneau de porte, une planche de bord, un siège ... L'habillage 2 comprend une face frontale 4 destinée à être visible et accessible pour un utilisateur, et une face arrière 6 destinée à être masquée lorsque l'habillage intérieur 2 est fixé dans le véhicule automobile. L'habillage 2 est multicouche. Il comprend une armature 8 rigide, une garniture 10 souple recouvrant l'armature 8 et surmoulée sur celle-ci, et un flocage 12 recouvrant la garniture 10 du côté opposé à l'armature 8. Le flocage 12 est situé du côté de la face frontale 4, et l'armature 8 est située du côté de la face arrière 6. L'armature 8 détermine la forme générale de l'habillage 2. Elle est obtenue de manière classique, par exemple par moulage par injection de matière plastique, telle que du polypropylène ou de l'ABS. La garniture 10 recouvre l'armature 8 pour conférer à l'habillage 2 une certaine souplesse au toucher afin d'améliorer la qualité perçue et le confort. La garniture 10 est réalisée dans un matériau compressible élastiquement au toucher afin de se comprimer lorsqu'un utilisateur appuie dessus. Le confort et la souplesse de la garniture dépendent notamment de sa nature et de son épaisseur. An object of the invention is to provide a vehicle interior trim conferring an impression of good perceived quality, which is easy to manufacture, and offering greater freedom of style. For this purpose, the invention proposes a vehicle interior trim of the aforementioned type, in which the trim is overmolded on the armature and flocked with fibers. According to other embodiments, the inner lining comprises one or more of the following characteristics, taken in isolation or in any technically possible combination: the lining is made of foam; the filling is made of gel; - the thickness of the lining is equal to or greater than 1 mm; the lining comprises thicker regions; the flocking fibers are textile fibers, in particular polyamide or polypropylene fibers; and the thickness of the flocking is equal to or greater than 0.1 mm. The invention also relates to a motor vehicle comprising an interior trim as defined above. The invention also relates to a method of manufacturing an inner liner as defined above, in which the lining is molded onto the support by injection molding, and then the lining is flocked with the fibers. The invention and its advantages will be better understood on reading the description which follows, given solely by way of example, and with reference to the appended drawings, in which: FIG. 1 is a sectional view of FIG. interior trim of a motor vehicle; - Figures 2 to 4 are views similar to that of Figure 1, illustrating steps of a method of manufacturing the inner lining of Figure 1; and Figures 5 and 6 are views similar to that of Figure 1 and illustrating particular embodiments. As shown in Figure 1, the casing 2 is intended to be fixed inside a motor vehicle to dress for example an armrest, a door panel, a dashboard, a seat ... The cladding 2 comprises a front face 4 intended to be visible and accessible to a user, and a rear face 6 intended to be hidden when the inner lining 2 is fixed in the motor vehicle. The skin 2 is multilayer. It comprises a rigid armature 8, a flexible lining 10 covering the armature 8 and overmolded on it, and a flocking 12 covering the lining 10 on the opposite side to the armature 8. The flocking 12 is located on the side of the face 4, and the armature 8 is located on the side of the rear face 6. The armature 8 determines the general shape of the casing 2. It is obtained in a conventional manner, for example by plastic injection molding, such as only polypropylene or ABS. The liner 10 covers the frame 8 to give the cladding 2 some flexibility to the touch to improve the perceived quality and comfort. The liner 10 is made of an elastically compressible material to the touch to compress when a user presses on it. The comfort and flexibility of the lining depend in particular on its nature and its thickness.
La garniture 10 est par exemple formée d'une mousse, notamment d'une mousse en polyuréthane. En variante, la garniture est formée d'un gel. La garniture 10 présente par exemple une épaisseur E égale ou supérieure à 1 mm, de préférence supérieure à 3 mm. Le flocage 12 est réalisé directement sur la garniture 10. Il comprend une couche d'adhésif 16 appliquée sur la surface supérieure 18 de la garniture 10 opposée à l'armature 8, et des fibres 20 fixées dans la couche d'adhésif 16. Les fibres 20 ont une extrémité emprisonnée dans la couche d'adhésif, et une extrémité libre. La qualité perçue et le toucher superficiel conféré par le flocage 12 dépendent notamment de la nature des fibres 20, de leur longueur libre (ou épaisseur du flocage), de leur disposition et de leur nombre. Les fibres 20 sont de préférence des fibres textiles, et par exemple des fibres en polyamide ou en polypropylène. Les fibres 20 présentent de préférence une longueur libre comprise entre 0.2 mm et 1 mm, par exemple 0.6 mm. Les fibres 20 sont de préférence disposées sensiblement perpendiculairement à la surface supérieure 18 de la garniture 10 pour conférer un toucher superficiel plus doux. L'habillage 2 confère une impression de bonne qualité du fait, d'une part, du rembourrage fourni par la garniture 10, et, d'autre part, de l'aspect visuel et du toucher superficiel doux et soyeux conférés par le flocage 12. L'habillage 2 est obtenu facilement et à faible coût du fait, d'une part, que la garniture 10 est surmoulée sur l'armature 8, et d'autre part que le flocage 12 est réalisé directement sur la garniture 10. The lining 10 is for example formed of a foam, in particular a polyurethane foam. Alternatively, the liner is formed of a gel. The lining 10 has for example a thickness E equal to or greater than 1 mm, preferably greater than 3 mm. The flocking 12 is carried out directly on the liner 10. It comprises an adhesive layer 16 applied on the upper surface 18 of the lining 10 opposite to the frame 8, and fibers 20 fixed in the adhesive layer 16. fibers 20 have one end trapped in the adhesive layer, and one free end. The perceived quality and the surface feel conferred by the flocking 12 depend in particular on the nature of the fibers 20, their free length (or thickness of the flocking), their arrangement and their number. The fibers 20 are preferably textile fibers, and for example polyamide or polypropylene fibers. The fibers 20 preferably have a free length of between 0.2 mm and 1 mm, for example 0.6 mm. The fibers 20 are preferably disposed substantially perpendicular to the upper surface 18 of the liner 10 to impart a softer surface feel. The cladding 2 confers a good quality impression due, on the one hand, the padding provided by the lining 10, and, on the other hand, the visual appearance and soft and silky surface feel conferred by the flocking 12 The cladding 2 is obtained easily and at low cost because, on the one hand, the lining 10 is overmolded on the frame 8, and on the other hand that the flocking 12 is made directly on the lining 10.
La garniture 10 obtenue par surmoulage de l'armature 8 permet une fabrication facile et économique de l'habillage, ainsi qu'un bon contrôle de l'épaisseur de la garniture 10. Il en résulte également que la garniture 10 est solidaire de l'armature 8, ce qui évite la formation de bourrelets dans la garniture 10 lors de l'assemblage de l'habillage 2 dans le véhicule 2. Le flocage 12 réalisé sur la garniture 10 facilite la fabrication de l'habillage 2 et évite la formation de bourrelets lors de l'assemblage de l'habillage 2 dans le véhicule 2. La réalisation d'un flocage 12 sur une garniture 10 surmoulée permet en outre une grande liberté de style, du fait que des formes très variées peuvent être conférée à la garniture 10 pendant le moulage, et que le flocage 12 permet de recouvrir facilement toute la garniture 10, ce qui n'est pas possible avec un revêtement tendu sur l'armature, et en particulier un revêtement bicouche comprenant une garniture et un textile de parement. De plus, il est envisageable de floquer seulement une partie de la garniture 10, par exemple pour des effets de style. Selon un procédé de fabrication illustré sur les figures 2 à 4, on fournit une armature 8, par exemple moulée par injection, et on la place dans une cavité 22 de moulage d'un moule 24 comprenant deux matrices 26 complémentaires définissant la cavité 22 entre elles (Figure 2). Ensuite, on injecte dans la cavité 22 de la matière en fusion destinée à constituer la garniture 10. La matière en fusion recouvre l'armature 8, et se surmoule sur celle-ci, assurant au final une bonne cohésion entre la garniture 10 et l'armature 8 (Figure 3). Ensuite, on sort l'armature 8 et la garniture 10 du moule 24, et on floque la garniture 10, de manière classique, dans un appareil de flocage. Lors du flocage, on applique la couche d'adhésif 16 sur la surface supérieure 18 de la garniture 10, puis on projette des fibres 20 sur cette surface supérieure 18 à l'aide d'une buse 28. Les fibres 20 viennent s'emprisonner dans la couche d'adhésif 16 (Figure 4). De manière connue, pour orienter les fibres 20 perpendiculairement à la surface supérieure 18, on crée un champ électrostatique pendant l'étape de projection des fibres 20. The lining 10 obtained by overmoulding of the frame 8 allows an easy and economical manufacture of the covering, as well as a good control of the thickness of the lining 10. It also results that the lining 10 is secured to the lining 10. reinforcement 8, which avoids the formation of beads in the liner 10 during assembly of the trim 2 in the vehicle 2. The flocking 12 made on the liner 10 facilitates the manufacture of the covering 2 and avoids the formation of bead during assembly of the trim 2 in the vehicle 2. The embodiment of a flocking 12 on an overmolded trim 10 also allows a great freedom of style, because very varied shapes can be conferred to the trim 10 during the molding, and that the flocking 12 can easily cover all the lining 10, which is not possible with a coating stretched over the frame, and in particular a bilayer coating comprising a lining and a textile of pare is lying. In addition, it is conceivable to flock only a portion of the lining 10, for example for style effects. According to a manufacturing method illustrated in FIGS. 2 to 4, a reinforcement 8, for example injection-molded, is provided and placed in a cavity 22 for molding a mold 24 comprising two complementary matrices 26 defining the cavity 22 between they (Figure 2). Then, the cavity 22 is injected with molten material intended to constitute the lining 10. The molten material covers the armature 8, and overmolds on it, finally ensuring a good cohesion between the lining 10 and the lining 10. frame 8 (Figure 3). Then, the frame 8 and the liner 10 are taken out of the mold 24, and the lining 10 is flocked, in a conventional manner, in a flocking apparatus. During flocking, the layer of adhesive 16 is applied to the upper surface 18 of the lining 10, and then fibers 20 are sprayed onto this upper surface 18 by means of a nozzle 28. The fibers 20 come to imprison themselves. in the adhesive layer 16 (Figure 4). In a known manner, to orient the fibers perpendicular to the upper surface 18, an electrostatic field is created during the projection step of the fibers 20.
Le procédé de fabrication avec surmoulage de la garniture 10 sur l'armature 8 et flocage de la garniture 10 permet une liberté stylistique plus grande. Tel qu'illustré sur la Figure 5, dans un mode de réalisation, la garniture 10 comprend une région 30 plus épaisse pour améliorer localement le confort, par exemple dans une zone d'appui privilégié pour un utilisateur, du fait de la fonction et/ou de la disposition de l'habillage 2 dans le véhicule. La région 30 plus épaisse définit sur la face frontale 4 un relief 32. Dans l'exemple illustré, le relief 32 possède des surfaces 34 en contre-dépouille. The manufacturing process with overmolding of the lining 10 on the frame 8 and flocking of the lining 10 allows greater stylistic freedom. As illustrated in Figure 5, in one embodiment, the liner 10 includes a thicker region 30 for locally improving comfort, for example in a preferred bearing area for a user, due to the function and or the layout of the trim 2 in the vehicle. The thicker region 30 defines on the front face 4 a relief 32. In the illustrated example, the relief 32 has surfaces 34 undercut.
En effet, du fait de la souplesse de la garniture 10, le relief 32 est démoulable, et le flocage permet de recouvrir entièrement le relief 32, y compris la surface en contre dépouille 34. Dans le mode de réalisation de la Figure 6, l'habillage 2 forme un accoudoir et est fixé sur un panneau 36 d'habillage intérieur d'une portière 38. Indeed, because of the flexibility of the lining 10, the relief 32 is demoldable, and flocking completely covers the relief 32, including the undercut surface 34. In the embodiment of FIG. cover 2 forms an armrest and is fixed on a panel 36 of interior trim of a door 38.
L'habillage 2 présente une section transversale sensiblement en C ouverte vers le panneau 36, et comprenant deux branches 40. L'habillage 2 est fixé sur le panneau 36 par les extrémités des branches 40. La portion supérieure 42 de l'habillage 2 définit une portion d'appui pour le coude. La garniture 10 est munie de régions 44 plus épaisses dans cette portion d'appui 42. La surface supérieure 18 de la garniture 10 présente à la jonction entre les branches 40 un rayon de courbure R faible, par exemple supérieur à 20 mm.
