Description

Planche de bord à volet de sac gonflable tenu sur une mousse à cellules ouvertes La présente invention concerne une planche de bord d'automobile munie d'un sac gonflable. On connaît déjà des planches de bord d'automobile qui comprennent, sur un substrat relativement rigide, une couche de mousse et une peau apparente. Une ouverture est formée dans le substrat pour le passage d'un sac gonflable lorsque celui-ci se déploie ; cette ouverture est fermée par un volet lors de la fabrication de la couche de mousse par introduction d'une matière fluide entre le substrat et la peau. The present invention relates to an automobile dashboard provided with an airbag. Automobile dashboards are already known which comprise, on a relatively rigid substrate, a layer of foam and an apparent skin. An opening is formed in the substrate for passage of an airbag as it deploys; this opening is closed by a flap during the manufacture of the foam layer by introducing a fluid material between the substrate and the skin.
La figure unique du dessin annexé représente une coupe agrandie d'une partie de planche de bord voisine d'un bord de l'ouverture de la planche de bord.The single figure of the accompanying drawing shows an enlarged section of a dashboard portion adjacent to an edge of the dashboard opening.
Plus précisément, la planche de bord comporte un substrat relativement rigide 10, par exemple de polyuréthanne, de copolymère de styrène et d'anhydride maléique, de polyoléfine ou autre. Le substrat 10 porte une couche de mousse 12 qui porte elle-même une peau 14, avantageusement formée par rotomoulage.More specifically, the dashboard comprises a relatively rigid substrate 10, for example polyurethane, copolymer of styrene and maleic anhydride, polyolefin or other. The substrate 10 carries a layer of foam 12 which itself carries a skin 14, advantageously formed by rotational molding.
Un volet 20 est destiné à fermer l'ouverture 16 de la planche de bord 10. Ce volet 20 comporte un cadre 22 qui est séparé d'un portillon 24 par une fente 26 ayant en plan une forme en U. La partie ouverte du U correspond à un bord d'articulation du portillon 24 du volet.A flap 20 is intended to close the opening 16 of the dashboard 10. This flap 20 comprises a frame 22 which is separated from a gate 24 by a slot 26 having a U-shaped plane. corresponds to an articulation edge of the gate 24 of the shutter.
Pour la fabrication de la planche de bord représentée sur la figure unique, une bande d'étanchéité 18, formée de mousse à cellules fermées, est collée au substrat 10 autour de l'ouverture 16. Le volet 20 est placé sur cette bande d'étanchéité 18, sans être collé à celle-ci ; il est simplement maintenu contre la bande d'étanchéité 18 afin que la fente en U 26 soit entièrement en face de cette bande.For the manufacture of the dashboard shown in the single figure, a sealing strip 18, formed of closed-cell foam, is glued to the substrate 10 around the opening 16. The flap 20 is placed on this strip. sealing 18, without being glued to it; it is simply held against the sealing strip 18 so that the U-slot 26 is entirely in front of this strip.
Lorsque le sac gonflable de la planche de bord repré- sentée sur la figure unique est déployé, la force qu'il exerce provoque sur le volet provoque le pivotement de celui-ci dont le bord arrache la mousse au niveau de la fente. Plus précisément, la mousse est arrachée à un emplacement quelconque de la largeur de la fente, soit directement au bord du portillon 24, soit au bord du cadre 22, soit entre les deux. Ainsi, la déchirure de la couche de mousse 12 n'est pas parfaitement maîtrisée. On peut envisager d'utiliser, pour la bande d'étan- chéité 18, une bande adhésive par ses deux faces, collée d'une part au substrat 10 et d'autre part au cadre 22 et au portillon 24. De cette manière, la mousse de la couche 12 est au contact d'une surface adhésive de la bande 18 dans la fente 26 et est donc retenue sur cette bande 18. Lorsque le portillon 24 est ouvert par un sac gonflable qui se déploie, la mousse est donc arrachée à partir du bord du portillonWhen the airbag of the dashboard shown in the single figure is deployed, the force it exerts causes the flap causes the pivoting thereof whose edge tears the foam at the slot. More specifically, the foam is ripped from a any location of the width of the slot, either directly to the edge of the gate 24, the edge of the frame 22, or in between. Thus, the tear of the foam layer 12 is not perfectly controlled. It is conceivable to use, for the sealing strip 18, an adhesive strip by its two faces, bonded on the one hand to the substrate 10 and on the other hand to the frame 22 and to the door 24. In this way, the foam of the layer 12 is in contact with an adhesive surface of the band 18 in the slot 26 and is thus retained on this band 18. When the gate 24 is opened by an inflatable bag that unfolds, the foam is torn off from the edge of the gate
24. L'emplacement de séparation de la mousse est maîtrisé.24. The separation location of the foam is controlled.
Cependant, cette disposition a l'inconvénient de créer une force de retenue du portillon 24 sur la bande de mousse d'étanchéité 18 ; ainsi, la force que doit exercer le sac gonflable doit être accrue . Il peut même arriver que le portillon 24 s'ouvre en arrachant la bande d'étanchéité 18.However, this arrangement has the disadvantage of creating a retaining force of the gate 24 on the sealing foam strip 18; thus, the force to be exerted by the air bag must be increased. It may even happen that the gate 24 opens by tearing the sealing strip 18.
L'invention a pour objet de remédier à l'inconvénient précité et de résoudre le problème de la localisation précise de l'emplacement d'arrachement de la couche de mousse 12 lors de l'ouverture du portillon 24.The object of the invention is to remedy the aforementioned drawback and to solve the problem of the precise location of the tear-off location of the foam layer 12 when opening the gate 24.
Selon l ' invention, l ' emplacement d' arrachement de la couche de mousse est déterminé au bord du portillon 24, grâce à l ' accrochage de la mousse de la couche 12 à la bande d'étanchéité 18 dans la fente 26, alors que les problèmes posés par le collage du portillon 24 à la bande de mousse 18 sont résolus parce que la bande d'étanchéité 18 n'est pas adhésive du côté du volet 20 et de la couche de mousse 12. Selon l'invention, la bande d'étanchéité 18 n'est adhésive que du côté du substrat 10, et elle est formée d'un matériau à porosité ouverte permettant la pénétration de la matière fluide utilisée pour la formation de la couche de mousse entre le substrat et la peau, par exemple d'une mousse à cellules ouvertes. De cette manière, lors de la fabrication de la couche de mousse 12, la mousse pénètre dans le matériau à porosité ouverte, par exemple les cellules ouvertes, de la bande 18 et se solidarise avec celle-ci. Par contre, le portillon 24 est simplement appliqué sur la bande d'étanchéité 18 et ne colle pas à celle-ci.According to the invention, the location of tearing of the layer of foam is determined at the edge of the gate 24, thanks to the attachment of the foam of the layer 12 to the sealing strip 18 in the slot 26, whereas the problems posed by the bonding of the gate 24 to the foam strip 18 are solved because the sealing strip 18 is not adhesive on the side of the flap 20 and the foam layer 12. According to the invention, the strip sealing member 18 is adhesive only on the side of the substrate 10, and it is formed of an open porous material permitting the penetration of the fluid material used for the formation of the foam layer between the substrate and the skin, by example of an open cell foam. In this way, during the manufacture of the foam layer 12, the foam penetrates the open porosity material, for example the open cells, of the strip 18 and becomes solid with it. On the other hand, the gate 24 is simply applied to the sealing strip 18 and does not stick to it.
Plus précisément, l'invention concerne une planche de bord ayant une ouverture de passage de sac gonflable, la partie de planche de bord ayant l ' ouverture étant du type qui comprend, sur un substrat, une couche de mousse et une peau apparente, l'ouverture formée dans le substrat étant normalement fermée par un volet formé dans une plaque, le volet ayant des dimensions supérieures à celles de l ' ouver- ture, de sorte que son bord se trouve en face du substrat de matière plastique, le volet étant maintenu sur le substrat avec interposition d'une bande d'étanchéité. Selon l'invention, la bande d'étanchéité est formée d'un matériau à porosité ouverte permettant la pénétration de la matière fluide utilisée pour la formation de la couche de mousse entre le substrat et la peau.More specifically, the invention relates to a dashboard having an airbag passage opening, the dashboard portion having the opening being of the type which comprises, on a substrate, a foam layer and an exposed skin, the aperture formed in the substrate being normally closed by a shutter formed in a plate, the shutter having dimensions greater than those of the aperture, so that its edge is opposite the plastic substrate, the shutter being maintained on the substrate with the interposition of a sealing strip. According to the invention, the sealing strip is formed of a material with an open porosity allowing penetration of the fluid material used for the formation of the layer of foam between the substrate and the skin.
De préférence, le matériau à porosité ouverte est une mousse à cellules ouvertes .Preferably, the open porosity material is an open cell foam.
Dans un mode de réalisation, le portillon est délimité dans la plaque par une fente en U formant un espace entre un cadre et le portillon, et la fente en U se trouve en face du substrat. Par exemple, la plaque dans laquelle est formé le volet est métallique .In one embodiment, the gate is delimited in the plate by a U-shaped slot forming a space between a frame and the gate, and the U-slot is opposite the substrate. For example, the plate in which the shutter is formed is metallic.
Ainsi , l ' invention se distingue de la technique anté- rieure en ce que la bande d'étanchéité est formée d'un matériau à porosité ouverte dont la porosité est adaptée aux propriétés de la matière fluide utilisée pour la formation de la couche de mousse 12 de la planche de bord, notamment à la fluidité et à la nature chimique de cette matière, afin que celle-ci puisse pénétrer dans les pores du matériau à porosité ouverte et donne, après polymérisation ou durcissement, une force d'accrochage de la couche de mousse 12 au matériau à porosité ouverte .Thus, the invention differs from the prior art in that the sealing strip is formed of an open-porosity material whose porosity is adapted to the properties of the fluid material used for the formation of the foam layer. 12 of the dashboard, including the fluidity and the chemical nature of the material, so that it can penetrate the pores of the open porosity material and gives, after polymerization or hardening, a gripping force of the foam layer 12 to the open porosity material.
La détermination de la nature chimique, de la porosité et des propriétés mécaniques du matériau à porosité ouverte dépend de la nature chimique et des propriétés de fluidité de la matière fluide de moussage. A titre indicatif, il est toujours possible d'utiliser, pour la bande d'étanchéité, une bande de mousse à cellules ouvertes d'une matière plastique de la même famille que la matière plastique de la matière fluide de moussage.The determination of the chemical nature, porosity and mechanical properties of the open-porosity material is dependent on the chemical nature and flow properties of the foaming fluid material. As an indication, it is always possible to use, for the sealing strip, an open cell foam web of a plastic material of the same family as the plastic material of the foaming fluid material.
Ainsi, la simple utilisation d'un matériau à porosité ouverte pour la mousse permet une détermination précise de l'emplacement d'arrachement de la couche de mousse 12, sans modification du comportement du portillon 24 à l'ouverture.Thus, the simple use of a material with open porosity for the foam allows a precise determination of the tear-off location of the foam layer 12, without modification of the behavior of the gate 24 at the opening.
Bien qu ' on ait décrit l ' invention en référence à un volet métallique ayant un portillon disposé dans un cadre et délimitant une fente, l'invention s'applique à des volets formés d'autres matières, par exemple d'une matière plastique, ainsi qu'à des volets n'ayant pas de cadre, la couche intermédiaire 12 pénétrant alors dans la bande d'étanchéité du bord du portillon jusqu'à l'extrémité de cette bande. Although the invention has been described with reference to a metal flap having a gate disposed in a frame and delimiting a slot, the invention applies to shutters formed of other materials, for example a plastic material, and shutters without a frame, the intermediate layer 12 then penetrating into the sealing strip of the edge of the door to the end of this strip.
