Description
La présente invention concerne un procédé de fabrication d'un habillageThe present invention relates to a method of manufacturing a skin
intérieur de véhicule automobile comprenant un support et une peau décorative recouvrant le support, du type comprenant l'étape d'appliquer de la matière chauffée destinée à former au moins une partie du motor vehicle interior comprising a support and a decorative skin covering the support, of the type comprising the step of applying heated material intended to form at least a portion of the
support contre la peau, de façon que la matière chauffée adhère à la peau en refroidissant. support against the skin, so that the heated material adheres to the skin while cooling.
Le document WO 97/47454 décrit des procédés de fabrication d'habillages intérieurs de véhicules automobiles de ce type. WO 97/47454 discloses methods for manufacturing interior linings of motor vehicles of this type.
Il est parfois demandé par les constructeurs automobiles d'apposer sur la peau des habillages intérieurs des inserts ornementaux, tels que des logos représentant la marque des constructeurs automobiles ou des logos fournissant une indication particulière, telle que la présence d'un airbag. It is sometimes required by car manufacturers to affix on the skin interior trim ornamental inserts, such as logos representing the brand of car manufacturers or logos providing a particular indication, such as the presence of an airbag.
Il est possible de coller un tel logo sur la peau après la fabrication de l'habillage intérieur. Néanmoins, ceci requiert une étape supplémentaire, et doit être réalisé avec précaution pour ne pas endommager la peau au moment où l'on applique l'insert contre celle-ci. It is possible to stick such a logo on the skin after the manufacture of the interior trim. Nevertheless, this requires an additional step, and must be done carefully to avoid damaging the skin when the insert is applied against it.
Un but de l'invention est de proposer un procédé de fabrication d'un habillage intérieur permettant de fixer un insert ornemental de façon simple et économique. An object of the invention is to provide a method of manufacturing an interior trim for fixing an ornamental insert simply and economically.
A cet effet, l'invention propose un procédé du type précité, dans lequel on recouvre au moins une zone d'un insert ornemental d'un adhésif thermoactivable, et on applique la zone de l'insert recouverte par l'adhésif thermoactivable sur la peau du côté opposé au support, de façon à ce que la chaleur de la matière chauffée active l'adhésif thermoactivable à travers la peau lorsque la matière chauffée est appliquée contre la peau, et que l'insert est ainsi collé sur la peau. For this purpose, the invention proposes a method of the aforementioned type, in which at least one zone of an ornamental insert is covered with a heat-activatable adhesive, and the zone of the insert coated with the heat-activatable adhesive is applied to the skin on the opposite side of the support, so that the heat of the heated material activates the heat-activatable adhesive through the skin when the heated material is applied against the skin, and that the insert is thus adhered to the skin.
Selon d'autres modes de mise en oeuvre, le procédé comprend une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou selon toutes les combinaisons techniquement possibles: - on applique l'insert recouvert d'adhésif thermoactivable sur la peau avant d'appliquer la matière chauffée contre la peau; 2890329 2 - on applique la matière chauffée contre la peau en disposant la peau dans un moule, puis en injectant la matière chauffée en fusion dans le moule pour la surmoulée sur la peau; on dispose l'insert recouvert de l'adhésif thermoactivable contre une paroi du moule et on dispose la peau contre la paroi du moule en l'appliquant sur au moins la zone de l'insert recouverte par l'adhésif thermoactivable avant d'injecter la matière chauffée en fusion dans le moule; - on fixe l'insert contre la paroi du moule à l'aide d'un adhésif apte à maintenir une force d'adhésion entre l'insert et le moule inférieure à la force d'adhésion fournie par l'adhésif thermoactivable entre l'insert et la peau une fois l'adhésif thermoactivable activé par la chaleur; - avant d'injecter la matière chauffée en fusion, on dispose une base dans le moule formant une partie du support, et on injecte la matière chauffée en fusion entre la peau et la base, la matière chauffée formant après refroidissement une couche intermédiaire formant une partie du support située entre la peau et la base; - la matière chauffée appliquée contre la peau est de la matière plastique. According to other embodiments, the method comprises one or more of the following characteristics, taken in isolation or in any technically possible combination: the heat-activated adhesive-coated insert is applied to the skin before apply the heated material against the skin; The heated material is applied to the skin by placing the skin in a mold and then injecting the heated material into the mold for overmolding on the skin; the insert coated with the heat-activatable adhesive is placed against a wall of the mold and the skin is placed against the wall of the mold by applying it to at least the zone of the insert covered by the heat-activatable adhesive before injecting the material heated in fusion in the mold; the insert is fixed against the wall of the mold by means of an adhesive capable of maintaining an adhesion force between the insert and the mold that is less than the adhesive force provided by the heat-activatable adhesive between the insert and the skin once the thermo-activatable adhesive activated by heat; before injecting the molten heated material, a base is placed in the mold forming part of the support, and the molten heated material is injected between the skin and the base, the heated material forming, after cooling, an intermediate layer forming a part of the support located between the skin and the base; the heated material applied against the skin is plastic.
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 schématique en perspective d'un habillage intérieur de véhicule automobile, - les Figures 2 à 4 sont des vues en coupe d'un moule, illustrant des 25 étapes successives d'un procédé conforme à l'invention mis en uvre pour obtenir l'habillage de la Figure 1, - la Figure 5 est une vue de détail de la Figure 2, - la Figure 6 est une vue analogue à celle de la Figure 1, illustrant un habillage intérieur selon une variante, et 2890329 3 - la Figure 7 est une vue analogue à celle de la Figure 3, illustrant une étape d'un procédé conforme à l'invention mis en oeuvre pour obtenir l'habillage de la Figure 6. 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 schematic perspective view of FIG. 2 to 4 are sectional views of a mold, illustrating successive steps of a method according to the invention used to obtain the cladding of FIG. 1. 5 is a view similar to that of FIG. 1, illustrating a variant interior trim, and FIG. 7 is a view similar to FIG. that of Figure 3, illustrating a step of a method according to the invention implemented to obtain the cladding of Figure 6.
Tel que représenté sur la Figure 1, l'habillage intérieur 2 de véhicule 5 automobile comprend un support en matière plastique 4 et une peau décorative 6 recouvrant le support 4. As shown in FIG. 1, the automobile vehicle interior trim 2 comprises a plastic support 4 and a decorative skin 6 covering the support 4.
L'habillage 2 est destiné à être fixé dans l'habitacle du véhicule automobile, par exemple pour recouvrir une planche de bord ou l'intérieur d'une porte. The casing 2 is intended to be fixed in the passenger compartment of the motor vehicle, for example to cover a dashboard or the inside of a door.
Le support 4 confère une rigidité suffisante à l'habillage 2, et la peau 6 constitue la partie visible de l'habillage 2 une fois celui-ci fixé dans le véhicule. La peau 6 est par exemple en plastique pour les véhicules de bas de gamme, et en tissu ou en cuir pour les véhicules haut de gamme. The support 4 gives sufficient rigidity to the cladding 2, and the skin 6 constitutes the visible part of the cladding 2 once it is fixed in the vehicle. The skin 6 is for example plastic for low-end vehicles, and fabric or leather for high-end vehicles.
Un insert ornemental 8 est fixé sur la peau 6. L'insert 8 représente par exemple un logo, tel que la marque du véhicule automobile ou un pictogramme. L'insert 8 est par exemple une plaque mince en plastique ou en métal, ou une feuille imprimée. An ornamental insert 8 is attached to the skin 6. The insert 8 represents for example a logo, such as the mark of the motor vehicle or a pictogram. The insert 8 is for example a thin plate of plastic or metal, or a printed sheet.
L'habillage 2 est représenté de façon schématique avec un contour sensiblement rectangulaire, l'insert 8 étant fixé au centre de la peau 6. The covering 2 is shown schematically with a substantially rectangular contour, the insert 8 being fixed at the center of the skin 6.
L'habillage 2 possède en variante une forme quelconque adaptée à l'élément d'habitacle qu'il doit recouvrir, et le logo 8 est placé en variante à un endroit différent, par exemple à la périphérie de la peau 6. The cladding 2 has alternatively any shape adapted to the cabin element that it must cover, and the logo 8 is alternatively placed at a different place, for example at the periphery of the skin 6.
L'habillage 2 est obtenu par la mise en oeuvre d'un procédé de fabrication dans lequel de la matière chauffée, par exemple de la matière synthétique telle que de la matière plastique, destinée à former le support est appliquée contre la peau, de façon à ce que la matière plastique adhère à la peau. The covering 2 is obtained by the implementation of a manufacturing method in which heated material, for example synthetic material such as plastic, intended to form the support is applied against the skin, so that the plastic adheres to the skin.
Pour ce faire, comme représenté sur les Figures 2 à 4, on utilise par exemple un moule 10 comprenant une partie inférieure 12 et une partie supérieure 14 déplaçables l'une par rapport à l'autre entre une position fermée (Figure 3) dans laquelle elles sont rapprochées et définissent entre elles une cavité 16 de moulage, et une position ouverte (Figure 2) dans laquelle elles sont écartées pour permettre d'accéder à l'intérieur du moule 10. To do this, as shown in FIGS. 2 to 4, use is made, for example, of a mold 10 comprising a lower portion 12 and an upper portion 14 movable relative to one another between a closed position (FIG. 3) in which they are close together and define between them a molding cavity 16, and an open position (FIG. 2) in which they are spaced to allow access to the interior of the mold 10.
La partie 12 comprend des buses 18 débouchant d'un côté dans la cavité 16 lorsque le moule 10 est fermé, et raccordées du côté opposé à une source d'alimentation en matière plastique en fusion. The portion 12 comprises nozzles 18 opening on one side into the cavity 16 when the mold 10 is closed, and connected on the opposite side to a molten plastic feed source.
La partie 14 comprend une région centrale 20 possédant une paroi 22 délimitant la cavité 16 et un rebord 24 périphérique s'étendant en direction de la partie 12. La partie 14 comprend des buses 26 débouchant sur la paroi 22 et raccordées à une source de vide. The portion 14 comprises a central region 20 having a wall 22 defining the cavity 16 and a peripheral rim 24 extending towards the portion 12. The portion 14 comprises nozzles 26 opening on the wall 22 and connected to a vacuum source .
Lors d'une première étape, et comme illustré sur la Figure 5, l'insert 8 est recouvert sur une face 30 destinée à être orientée vers la peau 6 d'un adhésif 32 thermoactivable, et sur une face 34 opposée, destinée à être la face visible de l'insert 8, d'un adhésif 36 qui est par exemple un adhésif sensible à la pression. In a first step, and as illustrated in FIG. 5, the insert 8 is covered on one face 30 intended to face the skin 6 with a thermo-activatable adhesive 32, and on an opposite face 34 intended to be the visible face of the insert 8, an adhesive 36 which is for example a pressure-sensitive adhesive.
Lors d'une deuxième étape, l'insert 8 est fixé à un emplacement déterminé contre la paroi 22, en appliquant l'insert 8 contre la paroi 22 à l'aide de l'adhésif 36. In a second step, the insert 8 is fixed at a specific location against the wall 22, by applying the insert 8 against the wall 22 with the adhesive 36.
Lors d'une troisième étape, la peau 6 est appliquée contre la paroi 22, et maintenue contre la paroi 22 en formant un vide entre la paroi 22 et la peau 6 à l'aide des buses 26 (Figure 2). In a third step, the skin 6 is applied against the wall 22, and held against the wall 22 forming a vacuum between the wall 22 and the skin 6 using the nozzles 26 (Figure 2).
Dans cette position, une face 38 de la peau 6, destinée à être visible, recouvre la face 30 et est en contact avec l'adhésif 32. In this position, a face 38 of the skin 6, intended to be visible, covers the face 30 and is in contact with the adhesive 32.
Lors d'une quatrième étape, le moule 10 est refermé (Figure 3). In a fourth step, the mold 10 is closed again (FIG. 3).
Lors d'une cinquième étape, la matière plastique en fusion est injectée à travers les buses 18 dans la cavité 16, et remplit la cavité 16 (Figure 3) . In a fifth step, the molten plastic is injected through the nozzles 18 into the cavity 16, and fills the cavity 16 (Figure 3).
La matière plastique en fusion est donc appliquée sur une face 39 de la peau 6 opposée à l'insert 8. La chaleur de la matière plastique en fusion traverse la peau 6 et atteint l'adhésif 32. Si une quantité de chaleur suffisante est apportée à l'adhésif 32, celui-ci est thermoactivé, de sorte que l'insert 8 est scellé sur la peau 6. The molten plastic material is thus applied to a face 39 of the skin 6 opposite to the insert 8. The heat of the molten plastic material passes through the skin 6 and reaches the adhesive 32. If a sufficient amount of heat is provided to the adhesive 32, the latter is thermoactivated, so that the insert 8 is sealed on the skin 6.
La quantité de chaleur apportée dépend de la température de la matière chauffée, de la conductivité thermique de la peau 6, de l'épaisseur de la peau 6 et de la durée pendant laquelle la chaleur est transférée à travers la peau 6. Par conséquent, en fonction de ces paramètres, il sera fait en sorte que la chaleur apportée à l'adhésif 32 soit suffisante pour son activation. The amount of heat supplied depends on the temperature of the heated material, the thermal conductivity of the skin 6, the thickness of the skin 6 and the time during which the heat is transferred through the skin 6. Therefore, depending on these parameters, it will be ensured that the heat provided to the adhesive 32 is sufficient for its activation.
En refroidissant, la matière plastique adhère à la peau 6. By cooling, the plastic adheres to the skin 6.
Lors d'une sixième étape, le moule 10 est ouvert (Figure 4). Les forces d'adhésion respectives de l'adhésif 32 une fois activé et de l'adhésif 36 sont choisies de sorte que la force d'adhésion produite par l'adhésif 32 entre l'insert 8 et la peau 6 est supérieure à la force d'adhésion produite par l'adhésif 36 entre l'insert 8 et le moule 6. Ainsi, à l'ouverture du moule 10, l'insert 8 se décolle de la paroi 20 et reste scellé sur la peau 6 sans altération de l'insert 8 ou de la peau 6. In a sixth step, the mold 10 is open (Figure 4). The respective adhesion forces of the activated adhesive 32 and adhesive 36 are chosen so that the adhesive force produced by the adhesive 32 between the insert 8 and the skin 6 is greater than the force adhesion produced by the adhesive 36 between the insert 8 and the mold 6. Thus, at the opening of the mold 10, the insert 8 is detached from the wall 20 and remains sealed on the skin 6 without altering the insert 8 or skin 6.
L'insert 8 est donc fixé sur la peau 6 en même temps que le support 4, sans opération supplémentaire, et sans risque d'altérer la peau. The insert 8 is attached to the skin 6 at the same time as the support 4, without additional operation, and without the risk of damaging the skin.
Tel que représenté sur la Figure 6, un habillage 2 selon une variante comprend un support 4 bicouches comprenant une base inférieure rigide 40 et une couche intermédiaire souple 42 interposée entre la peau 6 et la base 40. As shown in FIG. 6, an alternative covering 2 comprises a bilayer support 4 comprising a rigid lower base 40 and a flexible intermediate layer 42 interposed between the skin 6 and the base 40.
La base 40 fournit à l'habillage 2 sa rigidité. La couche intermédiaire 42 est par exemple une mousse et confère à l'habillage 2 une certaine 25 souplesse au toucher lorsque l'on appuie sur la peau 6. Cette souplesse est perçue comme un critère de qualité par les utilisateurs. The base 40 provides the cladding 2 its rigidity. The intermediate layer 42 is for example a foam and gives the cladding 2 a certain flexibility in touching when the skin is pressed 6. This flexibility is perceived as a criterion of quality by the users.
Un moule 10 pour la fabrication de l'habillage diffère de celui des Figures 2 à 4 en ce que les buses 18 sont reliées à une source de vide, et la partie 14 comprend des buses 46 traversant le rebord 24 et raccordées à une source d'alimentation en matière synthétique en fusion et sous pression. A mold 10 for the manufacture of the covering differs from that of Figures 2 to 4 in that the nozzles 18 are connected to a vacuum source, and the portion 14 comprises nozzles 46 passing through the flange 24 and connected to a source of heat. supply of synthetic material in fusion and under pressure.
Comme illustré sur la Figure 7, l'habillage 2 est obtenu de la même façon que précédemment, à ceci près que, avant de refermer le moule 10, on dispose la base 40 contre la partie 12 et on la maintient plaquée contre la partie 12 en créant un vide entre la base 40 et la partie 12 par l'intermédiaire des buses 18, puis on referme le moule et on injecte la matière synthétique en fusion dans la cavité 16, par l'intermédiaire des buses 46 débouchant dans la cavité 16 entre la peau 6 et la base 40. En refroidissant, la couche intermédiaire 42 adhère d'un côté à la base 40 et de l'autre côté à la peau 6. Comme précédemment, la chaleur de la matière en fusion permet d'activer l'adhésif thermoactivable recouvrant l'insert 8. As illustrated in FIG. 7, the covering 2 is obtained in the same way as before, except that, before closing the mold 10, the base 40 is placed against the part 12 and it is pressed against the part 12 by creating a vacuum between the base 40 and the portion 12 through the nozzles 18, then the mold is closed and the molten plastic is injected into the cavity 16, through the nozzles 46 opening into the cavity 16 between the skin 6 and the base 40. In cooling, the intermediate layer 42 adheres on one side to the base 40 and on the other side to the skin 6. As before, the heat of the molten material makes it possible to activate the heat-activatable adhesive covering the insert 8.
Dans une variante applicable à l'habillage de la Figure 1 ou 6, l'insert 8 dont la face 30 est recouverte de l'adhésif 32 est appliqué sur la peau 6 immédiatement après le démoulage de l'habillage 2, de façon que l'adhésif est activé par la chaleur de la matière du support 4 encore chaude. In a variant applicable to the covering of FIG. 1 or 6, the insert 8, the face 30 of which is covered with the adhesive 32, is applied to the skin 6 immediately after demolding of the covering 2, so that the adhesive is activated by the heat of the material of the support 4 still hot.
Dans une autre variante, le support 4 est fabriqué préalablement, la peau 6 est ensuite appliquée sur la matière du support encore chaude ou réchauffée, et l'insert 8 est appliqué sur la peau 6. Il n'est pas nécessaire d'appliquer l'insert 8 en exerçant une pression importante, ce qui simplifie l'opération et limite les risques d'altération de la peau 6. In another variant, the support 4 is manufactured beforehand, the skin 6 is then applied to the material of the support still hot or heated, and the insert 8 is applied to the skin 6. It is not necessary to apply the insert 8 exerting significant pressure, which simplifies the operation and limits the risk of skin damage 6.
