La pièce de panneau de porte 11 représentée partiellement à la FigureIn all that follows, the orientations are the usual orientations of a motor vehicle. Thus, the terms "interior", "exterior", "upper", "lower", "transverse" and "longitudinal" refer to the direction of movement of the vehicle and the position of a driver. The door panel part 11 partially shown in FIG.
1 est destinée à être fixée sur le garnissage intérieur d'une porte de véhicule automobile (non représentée), par exemple entre le vide-poches et une partie supérieure de ce garnissage.1 is intended to be fixed on the interior lining of a vehicle door automobile (not shown), for example between the storage compartment and an upper portion of this lining.
La pièce 11 comprend une armature de support 13 rigide, un tissu d'aspect 15 assemblé sur une surface intérieure 17 concave de l'armature 13, et une équerre 18 de maintien en position de l'armature 13.The piece 11 comprises a rigid support armature 13, a fabric of appearance 15 assembled on a concave inner surface 17 of the armature 13, and a bracket 18 for holding the armature 13 in position.
L'armature 13 comprend une partie supérieure 19 sensiblement verticale formant un médaillon et une partie inférieure 21 formant un accoudoir.The armature 13 comprises a substantially vertical upper portion 19 forming a medallion and a lower portion 21 forming an armrest.
La partie supérieure 19 comprend un corps 23 de support de tissu réalisé à base d'un matériau rigide et présentant une tranche inférieure 25 en forme de biseau.The upper part 19 comprises a body 23 of fabric support made of a rigid material and having a lower portion 25 shaped bevel.
La partie inférieure 21 présente une forme bombée vers l'intérieur du véhicule. Elle comprend une paroi d'appui 27 sensiblement horizontale adjacente à la partie supérieure 19. La paroi 27 présente une tranche extérieure 29 en forme de biseau disposée en regard de la tranche inférieure 25 du corps 23. Dans cet exemple, le tissu 15 est formé par une feuille multi-couches continue. Cette feuille comprend une couche intermédiaire 31 de mousse souple assemblée sur l'armature 13, et une couche 33 de revêtement textile souple assemblée sur une surface intérieure 35 de la couche de mousse 31.The lower part 21 has a curved shape towards the inside of the vehicle. It comprises a substantially horizontal bearing wall 27 adjacent to the upper portion 19. The wall 27 has an outer edge 29 in the form of a bevel disposed facing the lower edge 25 of the body 23. In this example, the fabric 15 is formed by a continuous multilayer sheet. This sheet comprises an intermediate layer 31 of flexible foam assembled on the frame 13, and a layer 33 of flexible textile coating assembled on an inner surface 35 of the foam layer 31.
La couche de mousse 31 délimite une surface masquée 36 du tissu sur laquelle est fixée l'armature 13, alors que la couche de revêtement textile 33 délimite une surface d'aspect 38 du tissu.The foam layer 31 delimits a masked surface 36 of the fabric on which the reinforcement 13 is fixed, while the textile covering layer 33 delimits an appearance surface 38 of the fabric.
Le tissu 15 comprend une région supérieure 37 fixée sur la partie supérieure 19, une région inférieure 39 fixée sur la partie inférieure 21 , et un repli intermédiaire à rebroussement 41 disposé entre la partie supérieure 19 et la partie inférieure 21.The fabric 15 comprises an upper region 37 fixed on the upper part 19, a lower region 39 fixed on the lower part 21, and an intermediate foldback 41 placed between the upper part 19 and the lower part 21.
Dans l'exemple illustré par la Figure 1 , le repli intermédiaire 41 est formé par deux bandes longitudinales 43A, 43B de tissu repliées l'une sur l'autre vers l'intérieur du véhicule. Ces bandes 43A et 43B sont enserrées partiellement entre la tranche inférieure 25 et la tranche extérieure 29. Le repli intérieur 41 délimite, sur la surface d'aspect 38 du tissu 15, une ligne de pliage 47 longitudinale et deux régions 49A et 49B de la surface d'aspect 38 situées de part et d'autre de la ligne de pliage 47. Les régions 49A et 49B sont situées respectivement en regard de la partie supérieure 19 et de la partie inférieure 21. Elles forment entre elles un angle intérieur inférieur à 160° et, dans cet exemple voisin de 90°.In the example illustrated in Figure 1, the intermediate fold 41 is formed by two longitudinal strips 43A, 43B of fabric folded one over the other towards the inside of the vehicle. These strips 43A and 43B are partially clamped between the lower edge 25 and the outer edge 29. The inner fold 41 defines, on the surface of appearance 38 of the fabric 15, a longitudinal fold line 47 and two regions 49A and 49B of the surface of appearance 38 located on either side of the fold line 47. The regions 49A and 49B are located respectively opposite the upper part 19 and the lower part 21. They form between them an internal angle of less than 160 ° and in this example close to 90 °.
Comme on le verra plus bas, la partie inférieure 21 est déplaçable par rapport à la partie supérieure 19 lors du montage de la pièce 11 pour former le repli intermédiaire 41 par pliage.As will be seen below, the lower portion 21 is movable relative to the upper portion 19 during assembly of the piece 11 to form the intermediate fold 41 by folding.
L'équerre 18 comprend une partie supérieure 51 rapportée sur une surface extérieure 53 du corps 23, et une partie inférieure 55 rapportée sur une surface inférieure 57 de la paroi 27. L'équerre 18 chevauche le repli intermédiaire 41 et maintient la pièce 11 en position après son montage.The bracket 18 comprises an upper portion 51 attached to an outer surface 53 of the body 23, and a lower portion 55 attached to a lower surface 57 of the wall 27. The bracket 18 overlaps the intermediate fold 41 and holds the workpiece 11 in place. position after mounting.
Comme illustré par la Figure 2, la pièce 11 est réalisée selon un procédé selon l'invention mis en œuvre en partie dans un moule 59 (Figure 2(a)). Le moule 59 comprend un demi-moule 61 de support du tissu 15, un demi-moule 63 de fermeture et des moyens 65 d'injection de matière plastique fondue dans le moule 59. Le demi-moule 61 comprend une partie 67 qui fait saillie vers le demi- moule 63.As illustrated in Figure 2, the part 11 is made according to a method according to the invention implemented in part in a mold 59 (Figure 2 (a)). The mold 59 comprises a half-mold 61 for supporting the fabric 15, a closure half-mold 63 and means 65 for injecting molten plastic material into the mold 59. The half-mold 61 comprises a portion 67 which protrudes to the half-mold 63.
Le demi-moule de fermeture 63 est mobile par rapport au demi-moule 61 entre une position d'ouverture du moule 59 et une position de fermeture du moule 59. Lorsque le tissu 15 est disposé dans le moule 59, et que le moule 59 est dans sa position de fermeture, le tissu d'aspect 15 et le demi-moule 63 de fermeture délimitent deux cavités d'injection 69 et 71 disjointes situées de part et d'autre de la partie saillante 67.The closing half-mold 63 is movable relative to the half-mold 61 between an open position of the mold 59 and a closed position of the mold 59. When the fabric 15 is placed in the mold 59, and the mold 59 is in its closed position, the appearance fabric 15 and the closure half-mold 63 delimit two injection cavities 69 and 71 disjoint located on either side of the projecting portion 67.
Les moyens d'injection 65 de matière plastique fondue débouchent dans les deux cavités 69 et 71.The injection means 65 of molten plastic material open into the two cavities 69 and 71.
Le procédé de réalisation de la pièce 11 comprend une étape de disposition du tissu 15 dans le moule, une étape de surmoulage simultané de la partie supérieure 19 et de la partie inférieure 21 , une étape de démoulage de la pièce 11 , une étape de déplacement relatif de la partie inférieure 21 par rapport à la partie supérieure 19, et une étape de fixation de l'équerre 18.The method for producing the part 11 comprises a step of disposing the fabric 15 in the mold, a step of simultaneous overmolding of the upper part 19 and the lower part 21, a demolding step of the part 11, a moving step relative of the lower part 21 with respect to the upper part 19, and a step of fixing the bracket 18.
Initialement, le moule 59 est maintenu dans sa position d'ouverture. Lors de l'étape de disposition du tissu 15 dans le moule, la couche 33 de revêtement textile est appliquée contre le demi-moule de support 61. La couche intermédiaire de mousse 31 s'étend alors en regard du moule de fermeture 63. Le moule 59 est ensuite fermé. La région 73 du tissu 15 appliquée sur la partie saillante 67 entre alors en contact avec le demi-moule de fermeture 63 pour délimiter les deux cavités d'injection 69 et 71 disjointes.Initially, the mold 59 is held in its open position. During the step of placing the fabric 15 in the mold, the layer 33 of textile coating is applied against the support half-mold 61. The intermediate layer of foam 31 then extends facing the closure mold 63. mold 59 is then closed. The region 73 of the fabric 15 applied to the projecting portion 67 then comes into contact with the closure half-mold 63 to delimit the two disjoint injection cavities 69 and 71.
La matière plastique fondue est alors injectée simultanément dans les deux cavités d'injection 69, 71 pour former respectivement la partie supérieure 19 et la partie inférieure 21 de l'armature 13, après refroidissement.The molten plastic material is then injected simultaneously into the two injection cavities 69, 71 to form respectively the upper part 19 and the lower part 21 of the armature 13, after cooling.
Puis, la pièce 11 est démoulée comme représenté à la Figure 2(b). La partie supérieure 19 et la partie inférieure 21 sont alors sensiblement coplanaires.Then, the piece 11 is demolded as shown in Figure 2 (b). The upper part 19 and the lower part 21 are then substantially coplanar.
Lors de l'étape de déplacement, la partie inférieure 21 est déplacée vers le haut par pivotement autour de la partie de tissu 73. Lors de ce déplacement, les bandes 43A et 43B du tissu 15 situées respectivement en regard des tranches inférieure et extérieure 25, 29 s'appliquent l'une contre l'autre pour former le repli 41.During the displacement step, the lower portion 21 is moved upwardly by pivoting around the tissue portion 73. During this movement, the bands 43A and 43B of the fabric 15 respectively facing the lower and outer slices 25 , 29 apply against each other to form the fold 41.
L'équerre 18 est ensuite fixée à l'arrière de l'armature 13 pour maintenir en position la partie inférieure 21 par rapport à la partie supérieure 19, de sorte que ces parties 19 et 21 sont sensiblement orthogonales.The bracket 18 is then attached to the rear of the frame 13 to maintain in position the lower portion 21 relative to the upper portion 19, so that these portions 19 and 21 are substantially orthogonal.
Par ailleurs, l'équerre 18 maintient constante la distance entre la tranche inférieure 25 et la tranche extérieure 29 pour enserrer le repli 41.Furthermore, the bracket 18 keeps the distance between the lower edge 25 and the outer edge 29 constant so as to grip the fold 41.
Le tissu 15 étant maintenu tendu lors du surmoulage de l'armature 13, la couche de revêtement textile 33 est dépourvue de plis et la surface d'aspect 38 de la pièce 11 présente un aspect esthétique satisfaisant.Since the fabric 15 is held taut during overmolding of the armature 13, the textile covering layer 33 is free of wrinkles and the appearance surface 38 of the part 11 has a satisfactory aesthetic appearance.
Le procédé selon l'invention permet donc d'obtenir une pièce 11 d'aspect esthétique améliorée, par des moyens simples et peu coûteux, avec une seule étape d'injection de l'armature 13.The method according to the invention thus makes it possible to obtain a piece 11 of improved aesthetic appearance, by simple and inexpensive means, with a single step of injection of the armature 13.
La deuxième pièce selon l'invention 81 est représentée sur la Figure 3. La partie supérieure 19 et la partie inférieure 21 comprennent des prolongements extérieurs respectifs 83 et 85 qui font saillie extérieurement et vers le bas par rapport au corps 23 et à la paroi 27. Les prolongements 83 et 85 s'étendent sensiblement parallèlement l'un rapport à l'autre pour enserrer le repli 41.The second part according to the invention 81 is shown in FIG. 3. The upper part 19 and the lower part 21 comprise respective external extensions 83 and 85 which project outwardly and downwards by relative to the body 23 and the wall 27. The extensions 83 and 85 extend substantially parallel to each other to enclose the fold 41.
La pièce 11 présente alors une section transversale sensiblement en forme de Y au voisinage du repli 41. Les prolongements 83 et 85 sont maintenus en position l'un par rapport à l'autre par une pince 87 qui chevauche extérieurement ces prolongements 81 et 83.The piece 11 then has a substantially Y-shaped cross section in the vicinity of the fold 41. The extensions 83 and 85 are held in position relative to each other by a clamp 87 which externally overlaps these extensions 81 and 83.
Les prolongements 83 et 85 permettent de générer des plans de glissement entre les deux parties 19 et 21 de l'armature 13, ce qui améliore la mise en forme du tissu 15. En effet, le maintien du tissu 15 au niveau du repli 41 est amélioré, ainsi que celui de la pince 87 sur les prolongements 83 et 85.The extensions 83 and 85 make it possible to generate sliding planes between the two parts 19 and 21 of the armature 13, which improves the shaping of the fabric 15. Indeed, the maintenance of the fabric 15 at the level of the fold 41 is improved, as well as that of the clamp 87 on the extensions 83 and 85.
La troisième pièce 91 selon l'invention représentée sur la Figure 4(c) diffère de la première pièce 11 en que la partie supérieure 19 et la partie inférieure 21 de l'armature 13 sont reliées entre elles par une charnière 93 longitudinale venue de matière avec les parties 19 et 21.The third piece 91 according to the invention shown in FIG. 4 (c) differs from the first piece 11 in that the upper part 19 and the lower part 21 of the frame 13 are connected to each other by a longitudinal hinge 93 made of material with parts 19 and 21.
La charnière 93 s'étend à l'extérieur du repli 41. Elle présente une épaisseur inférieure à l'épaisseur des parties 19 et 21.The hinge 93 extends outside the fold 41. It has a thickness less than the thickness of the parts 19 and 21.
Pour réaliser la troisième pièce 91 , le moule 59 représenté sur la Figure 4(a) diffère du moule représenté sur la Figure 2(a) en ce que le demi- moule de fermeture 63 comprend une partie saillante 95. Au contraire, le demi- moule de support 61 est dépourvu de partie saillante 67.To make the third piece 91, the mold 59 shown in Fig. 4 (a) differs from the mold shown in Fig. 2 (a) in that the half-closure mold 63 comprises a protruding portion 95. On the contrary, the half - Support mold 61 has no protruding portion 67.
Lorsque le tissu 15 est placé dans le moule 59 et que le moule 59 est disposé dans sa position de fermeture, la partie saillante 95 est située à l'écart de la couche de mousse 31. Le tissu 15 délimite avec le demi-moule de fermeture 63 une cavité unique 99 d'injection.When the fabric 15 is placed in the mold 59 and the mold 59 is disposed in its closed position, the projecting portion 95 is located away from the foam layer 31. The fabric 15 defines with the half-mold of closing 63 a single injection cavity 99.
La cavité 99 présente, en regard de la partie saillante 95, une région d'épaisseur inférieure aux régions adjacentes. La pièce 91 présente donc, après l'étape de surmoulage, une rainure longitudinale 97 délimitant la charnière 93. The cavity 99 has, opposite the projecting portion 95, a region of lower thickness than the adjacent regions. The piece 91 thus has, after the overmolding step, a longitudinal groove 97 defining the hinge 93.
