Description

Panneau de garnissage souple de véhicule automobile comprenant unFlexible trim panel for a motor vehicle comprising a

pictogramme rétroéclairé La présente invention concerne un panneau de garnissage souple pour véhicule automobile, du type comprenant au moins une zone formant un pictogramme, ledit pictogramme étant illuminé au moyen d'une source de lumière dis-posée sous le panneau de garnissage, le panneau de garnissage comprenant une peau translucide formant la surface externe du panneau et une couche de mousse souple sous la peau translucide. L'invention concerne également un véhicule automobile comprenant un tel panneau de garnissage. Par pictogramme, nous entendons tout dessin figuratif ou symbolique utilisé à des fins de communication, y compris des signes alphanumériques. Dans les panneaux connus de ce type, la source de lumière est disposée sous la couche de mousse. La lumière traverse donc la couche de mousse puis la peau translucide où elle est diffusée selon la forme du pictogramme délimitée par un masque. Le document FR-2 824 510 décrit par exemple un panneau de gar- nissage de ce type. Cependant, le passage dans la couche de mousse entraîne également une diffusion de la lumière à l'intérieur de celle-ci en raison de la présence d'air à l'intérieur de la mousse. Ceci entraîne une diffusion de la lumière à l'extérieur du masque. L'image du pictogramme devient donc imprécise et l'effet esthétique ob- tenu n'est pas satisfaisant. L'un des objectifs de l'invention est de pallier cet inconvénient en proposant un panneau de garnissage souple du type précité dans lequel l'éclairage du pictogramme est réalisé de façon précise et l'image obtenue est nette sans diffusion de lumière autour de celle-ci.  BACKGROUND OF THE INVENTION The present invention relates to a flexible lining panel for a motor vehicle, of the type comprising at least one zone forming a pictogram, said pictogram being illuminated by means of a light source placed under the lining panel, the panel of lining comprising a translucent skin forming the outer surface of the panel and a layer of soft foam under the translucent skin. The invention also relates to a motor vehicle comprising such a trim panel. By pictogram we mean any figurative or symbolic design used for communication purposes, including alphanumeric signs. In known panels of this type, the light source is disposed under the foam layer. The light then passes through the layer of foam then the translucent skin where it is diffused according to the shape of the pictogram delimited by a mask. Document FR-2,824,510 describes, for example, a packing panel of this type. However, the passage in the foam layer also causes light to diffuse into it because of the presence of air inside the foam. This causes light to scatter outside the mask. The image of the pictogram thus becomes imprecise and the aesthetic effect obtained is not satisfactory. One of the objectives of the invention is to overcome this drawback by proposing a flexible lining panel of the aforementioned type in which the illumination of the pictogram is made accurately and the image obtained is clear without light scattering around that -this.

A cet effet, l'invention concerne un panneau de garnissage du type précité, dans lequel la couche de mousse comprend une ouverture disposée en regard du trajet de passage de la lumière émise par la source de lumière et de la zone formant pictogramme, un élément de matériau souple translucide étant fixé à la peau dans ladite ouverture de sorte à transmettre la lumière de la source de lumière à la peau dans la zone formant pictogramme. Selon d'autres caractéristiques du panneau de garnissage : - l'élément de matériau souple translucide est un film en matériau polymère recouvrant l'ouverture de la couche de mousse ; -l'élément de matériau souple translucide est un coussin de gel remplissant au moins partiellement l'ouverture de la couche de mousse ; le panneau de garnissage comprend un insert rigide translucide disposé sous la couche de mousse souple, au moins en travers de l'ouverture de ladite couche de mousse ; - le panneau de garnissage comprend une plaque de matériau rigide disposée sous la couche de mousse souple, ladite plaque comprenant une ouverture disposée en regard de l'ouverture de la couche de mousse souple ; - le panneau de garnissage comprend un masque comprenant au moins une ouverture de la forme du pictogramme, ledit masque laisse passer la lumière à travers l'ouverture et bloque celle-ci autour de l'ouverture, ledit masque est dis-posé dans le trajet de passage de la lumière entre la source de lumière et la peau translucide ; - le masque est disposé entre la peau translucide et l'élément de matériau souple ou entre l'élément de matériau souple et la source de lumière ; - le masque est imprimé sur la surface interne de la peau translucide ou sur la surface supérieure ou sur la surface inférieure de l'élément de matériau souple ; et - le masque est un élément indépendant. L'invention concerne également un véhicule automobile comprenant un panneau de garnissage tel que décrit ci-dessus, ledit panneau étant appliqué contre au moins une partie de l'habitacle dudit véhicule automobile.  For this purpose, the invention relates to a lining panel of the aforementioned type, in which the layer of foam comprises an opening arranged facing the path of passage of the light emitted by the light source and the pictogram zone, a component translucent flexible material being attached to the skin in said opening so as to transmit light from the light source to the skin in the pictogram area. According to other features of the trim panel: the translucent flexible material element is a film of polymer material covering the opening of the foam layer; the translucent flexible material element is a gel cushion filling at least partially the opening of the foam layer; the trim panel comprises a translucent rigid insert disposed under the soft foam layer, at least across the opening of said foam layer; - The lining panel comprises a rigid material plate disposed under the layer of flexible foam, said plate comprising an opening disposed opposite the opening of the flexible foam layer; - The trim panel comprises a mask comprising at least one opening of the form of the pictogram, said mask passes the light through the opening and blocks it around the opening, said mask is placed in the path passage of light between the light source and the translucent skin; the mask is disposed between the translucent skin and the element of flexible material or between the element of flexible material and the light source; the mask is printed on the inner surface of the translucent skin or on the upper surface or on the lower surface of the element of flexible material; and - the mask is an independent element. The invention also relates to a motor vehicle comprising a trim panel as described above, said panel being applied against at least a portion of the passenger compartment of said motor vehicle.

D'autres aspects et avantages de l'invention apparaîtront au cours de la description qui suit, donnée à titre d'exemple et faite en référence aux dessins annexés, dans lesquels : - la Fig. 1 est une représentation schématique d'un panneau de garnissage selon un premier mode de réalisation de l'invention, - la Fig. 2 est une représentation schématique d'un panneau de garnissage selon un deuxième mode de réalisation de l'invention. Dans la description, on entend par externe ce qui est visible dans l'habitacle du véhicule automobile et par interne ce qui n'est pas visible. Les termes supérieur et inférieur sont définis par rapport à une direction partant de la paroi de l'habitacle et allant vers l'intérieur de l'habitacle. En référence aux Fig., on a représenté un panneau de garnissage souple 1 comprenant une peau translucide 2 et une couche de mousse souple 4 sous la peau translucide 2. La couche de mousse souple 4 est par exemple une mousse de polyuréthane adhérant à la peau translucide 2. Cet ensemble peut être conformé de la façon souhaitée pour s'adapter au garnissage d'un véhicule automobile. La sur-face externe 6 formée par la peau translucide 2 est par exemple sensiblement plane ou présente des zones en saillies ou en creux, par exemple pour signaler la présence de boutons de commande de fonctions du véhicule sous l'ensemble peau 2 / couche de mousse 4. Au moins une zone 8 du panneau de garnissage 1 comprend un pictogramme (non représenté) rétroéclairé. Par rétroéclairé, on entend qu'une source de lumière 10 est disposée sous le panneau de garnissage et émet de la lumière, selon un faisceau F représenté sur les Fig, qui est diffusée dans la peau translucide 2 dans la zone 8. De façon connue, la source de lumière 10 est disposée dans une boîte à lumière 12 comprenant une ouverture supérieure 14 recouverte par le panneau de garnissage 1. La source de lumière 10 est par exemple une diode électroluminescente ou autre. Afin d'éviter la diffusion de la lumière dans la couche de mousse souple 4, la couche de mousse 4 comprend une ouverture 16 disposée en regard de l'ouverture supérieure 14 de la boîte à lumière 12 et dans le trajet du faisceau F de lumière. L'ouverture 16 est agencée pour le faisceau F de lumière ne pénètre pas dans la couche de mousse 4, comme représenté sur les Fig. Ainsi la zone 8 est dépourvue de mousse sous la peau translucide 2. II se pose alors un problème de touché et de texture dans la zone 8. En effet, il est souhaitable d'avoir un touché similaire sur tout le panneau de garnissage 1 que la mousse soit présente sous la peau 2 ou non. A cet effet, un élément 18 de matériau souple translucide est fixé à la peau souple 2 dans l'ouverture 16 de la couche de mousse 4. L'élément 18 de matériau souple est choisi pour offrir un touché sur la zone 8 similaire au touché du reste du panneau de garnissage 1, de sorte qu'on ne sente pas la transition entre les zones du panneau où la couche de mousse 4 est présente et les zones 8 de pictogramme rétroéclairé. L'élément 18 est translucide et est traversé par le faisceau F de lumière de sorte qu'il laisse passer la lumière en provenance de la source de lumière 10. Ainsi, la lumière est transmise de la source de lumière 10 à la zone de pictogramme 8 de la peau 2 sans être diffusée dans la couche de mousse 4. Selon un premier mode de réalisation représenté sur la Fig. 1, l'élément 18 est un film en matériau polymère 20 recouvrant l'ouverture 16 de la couche de mousse 4. Le film 20 est collé ou soudé à la face inférieure de la peau 2 dans la zone 8 et s'étend au-dessus de l'ouverture 16 en recouvrant sensiblement les bords de cette ouverture. Le film 20 est par exemple collé préalablement à la formation de la couche de mousse 4 qui est injectée sur la peau 2 dans une cavité de moulage avec des moyens permettant de former l'ouverture 16, selon un pro-cédé connu.  Other aspects and advantages of the invention will become apparent from the following description, given by way of example and with reference to the accompanying drawings, in which: FIG. 1 is a schematic representation of a trim panel according to a first embodiment of the invention; FIG. 2 is a schematic representation of a trim panel according to a second embodiment of the invention. In the description, external means what is visible in the passenger compartment of the motor vehicle and internally what is not visible. The terms upper and lower are defined with respect to a direction starting from the wall of the passenger compartment and going towards the interior of the passenger compartment. Referring to Fig., There is shown a flexible lining panel 1 comprising a translucent skin 2 and a flexible foam layer 4 under the translucent skin 2. The flexible foam layer 4 is for example a polyurethane foam adhering to the skin translucent 2. This assembly can be shaped as desired to fit the lining of a motor vehicle. The outer surface 6 formed by the translucent skin 2 is for example substantially flat or has protruding or recessed areas, for example to indicate the presence of vehicle function control buttons under the skin 2 / layer of foam 4. At least one zone 8 of the trim panel 1 comprises a pictogram (not shown) backlit. By backlit means that a light source 10 is disposed under the lining panel and emits light, according to a beam F shown in FIGS, which is diffused in the translucent skin 2 in the zone 8. In a known manner the light source 10 is arranged in a light box 12 comprising an upper opening 14 covered by the lining panel 1. The light source 10 is for example a light-emitting diode or the like. In order to prevent the diffusion of light into the flexible foam layer 4, the foam layer 4 comprises an opening 16 arranged facing the upper opening 14 of the light box 12 and in the path of the light beam F . The opening 16 is arranged for the beam F of light does not penetrate into the foam layer 4, as shown in Figs. Thus the zone 8 is devoid of foam under the translucent skin 2. There is then a problem of touch and texture in the zone 8. Indeed, it is desirable to have a similar touch on the entire trim panel 1 that the foam is present under the skin 2 or not. For this purpose, an element 18 of translucent flexible material is attached to the flexible skin 2 in the opening 16 of the foam layer 4. The element 18 of flexible material is chosen to provide a touch on the zone 8 similar to the touchdown from the rest of the trim panel 1, so that we do not feel the transition between the areas of the panel where the foam layer 4 is present and the zones 8 pictogram backlit. The element 18 is translucent and is traversed by the beam F of light so that it passes light from the light source 10. Thus, the light is transmitted from the light source 10 to the pictogram area 8 of the skin 2 without being diffused in the foam layer 4. According to a first embodiment shown in FIG. 1, the element 18 is a film of polymer material 20 covering the opening 16 of the foam layer 4. The film 20 is glued or welded to the lower face of the skin 2 in the zone 8 and extends beyond above the opening 16 substantially covering the edges of this opening. The film 20 is for example glued prior to the formation of the foam layer 4 which is injected onto the skin 2 in a molding cavity with means for forming the opening 16, according to a known method.

Selon un deuxième mode de réalisation représenté sur la Fig. 2, l'élément 18 est un coussin de gel 22 remplissant au moins partiellement ou totalement l'ouverture 16 de la couche de mousse 4. Le coussin 22 est collé à la face inférieure de la peau dans la zone 8 et s'étend en travers de l'ouverture 16. Le gel est par exemple à base d'un matériau polymère translucide tel que, par exemple, du silicone ou du polyuréthane. Le coussin 22 est par exemple collé préalablement à la formation de la couche de mousse 4 qui est injectée sur la peau 2 autour du coussin 22 dans une cavité de moulage. Le panneau de garnissage 1 est posé sur une plaque 24 en matériau plastique, par exemple du polypropylène. La plaque 24 recouvre la boîte à lumière 12 et comprend au moins une ouverture en regard de l'ouverture supérieure 14 de la boîte à lumière de sorte à laisser passer le faisceau F de lumière. La plaque 24 est donc interposée entre la boîte à lumière 12 et la couche de mousse 4 et s'étend sensiblement sous la totalité du panneau de garnissage 1. Cette plaque 24 permet de rigidifier le panneau de garnissage 1 de sorte que celui-ci ne s'enfonce pas lorsqu'un appui est exercé sur lui. Selon un mode de réalisation, on prévoit en outre un insert 26 translucide et rigide en matériau plastique interposé entre la plaque 24 et la boîte à lumière 12. Cet insert 26 recouvre l'ouverture 14 de la boîte à lumière et pénètre dans l'ouverture de la plaque 24. Cet insert permet de renforcer la rigidité du panneau de garnissage 1 et d'assurer une meilleure diffusion de la lumière vers la peau translucide 2. La zone 8 peut être uniformément éclairée ou seulement partiellement de sorte à éclairer une forme particulière de pictogramme. Cette forme est réalisée au moyen d'un masque (non représenté) comprenant au moins une ouverture de la forme du pictogramme. Ce masque laisse passer la lumière à travers son ouverture et bloque celle-ci autour de l'ouverture. Le masque est disposé dans le trajet de passage de la lumière entre la source de lumière 10 et la peau translucide 2.  According to a second embodiment shown in FIG. 2, the element 18 is a gel cushion 22 filling at least partially or completely the opening 16 of the foam layer 4. The cushion 22 is glued to the lower face of the skin in the zone 8 and extends into The gel is, for example, based on a translucent polymer material such as, for example, silicone or polyurethane. The cushion 22 is for example glued prior to the formation of the foam layer 4 which is injected on the skin 2 around the cushion 22 in a mold cavity. The lining panel 1 is placed on a plate 24 of plastic material, for example polypropylene. The plate 24 covers the light box 12 and comprises at least one opening facing the upper opening 14 of the light box so as to let the beam F of light. The plate 24 is thus interposed between the light box 12 and the foam layer 4 and extends substantially under the entire of the lining panel 1. This plate 24 stiffens the lining panel 1 so that it does not do not sink when support is exerted on him. According to one embodiment, there is further provided a translucent and rigid insert 26 of plastic material interposed between the plate 24 and the light box 12. This insert 26 covers the opening 14 of the light box and enters the opening of the plate 24. This insert makes it possible to reinforce the stiffness of the lining panel 1 and to ensure a better diffusion of the light towards the translucent skin 2. The zone 8 can be uniformly illuminated or only partially so as to illuminate a particular shape of pictogram. This shape is achieved by means of a mask (not shown) comprising at least one opening of the form of the pictogram. This mask lets light through its opening and blocks it around the opening. The mask is disposed in the path of passage of light between the light source 10 and the translucent skin 2.

Le masque peut être un élément rapporté ou être imprimé directement sur un élément du panneau de garnissage, par exemple par des techniques de tampographie, d'héliographie, d'impression ou de marquage à chaud. Selon divers modes de réalisations, dans le cas d'un masque imprimé, le masque est imprimé sur la face inférieure de la peau translucide 2 ou sur la face supérieure ou inférieure du film 20 ou du coussin 22. Dans le cas d'un élément rapporté, le masque est disposé entre la peau 2 et l'élément de matériau souple 18 ou entre l'élément de matériau souple 18 et la plaque 24 ou entre la plaque 24 et la boîte à lumière 12 ou entre la plaque 24 et l'insert 26 ou entre l'insert 26 et la boîte à lumière 12.  The mask may be an insert or may be printed directly on an element of the trim panel, for example by pad printing, heliography, printing or hot stamping techniques. According to various embodiments, in the case of a printed mask, the mask is printed on the underside of the translucent skin 2 or on the upper or lower side of the film 20 or the cushion 22. In the case of an element reported, the mask is disposed between the skin 2 and the flexible material member 18 or between the flexible material member 18 and the plate 24 or between the plate 24 and the light box 12 or between the plate 24 and the insert 26 or between the insert 26 and the light box 12.

Le panneau de garnissage décrit ci-dessus permet d'obtenir une zone 8 de pictogramme éclairée de façon nette et sans débordement autour du pictogramme du fait d'une diffusion de la lumière dans la couche de mousse 4. De plus, la zone 8 offre un touché sensiblement identique au touché offert par la couche de mousse 4, malgré l'ouverture 16 pratiquée dans cette couche de mousse 4.25  The trim panel described above makes it possible to obtain a zone 8 of pictogram that is clearly illuminated and without overflow around the pictogram because of the diffusion of light in the foam layer 4. In addition, the zone 8 offers a touch substantially identical to the touch offered by the layer of foam 4, despite the opening 16 made in this layer of foam 4.25
