Description
Panneau de garnissage de véhicule automobile comprenant un pictogramme rétroéclairé sur un support coloré La présente invention concerne un panneau de garnissage pour véhicule automobile, du type comprenant au moins une zone formant pictogramme, ledit pictogramme étant illuminé au moyen d'une source de lumière disposée sous le panneau de garnissage, le panneau de garnissage comprenant une peau translucide formant la surface externe du panneau de garnissage et une couche de support disposée contre la peau entre la source de lumière et au moins la zone formant pictogramme. The present invention relates to a lining panel for a motor vehicle, of the type comprising at least one pictogram zone, said pictogram being illuminated by means of a light source arranged under a light source. the trim panel, the trim panel comprising a translucent skin forming the outer surface of the trim panel and a support layer disposed against the skin between the light source and at least the pictogram area.
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 du type décrit ci-dessus, la source de lumière est disposée sous la couche de support. La lumière traverse donc la couche de support 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 garnissage de ce type. Cependant, le passage de la lumière dans la couche de support entraîne également une diffusion de la lumière à l'intérieur de celle-ci en raison de la cristallinité ou de la charge du matériau polymère formant la couche de support. Ceci entraîne une diffusion de la lumière à l'extérieur de la zone formant pictogramme. L'image du pictogramme devient donc imprécise et l'effet esthétique obtenu n'est pas satisfaisant. 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 the known panels of the type described above, the light source is disposed under the support layer. The light then passes through the support layer and 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 of light into the support layer also causes light to scatter therein due to the crystallinity or charge of the polymeric material forming the support layer. This causes the light to scatter outside the pictogram area. The image of the pictogram becomes imprecise and the aesthetic effect obtained is not satisfactory.
L'un des buts de l'invention est de pallier cet inconvénient en proposant un panneau de garnissage du type précité dans lequel l'éclairage du pictogramme est réalisé de façon précise et l'image obtenue est nette et ressort clairement par rapport à la zone l'entourant. A cet effet, l'invention concerne un panneau de garnissage du type précité, dans lequel la couche de support est teintée de sorte à former un filtre passe-haut pour la lumière provenant de la source de lumière. La coloration de la couche de support agissant comme filtre passe-haut permet de filtrer les faibles intensités lumineuses responsables de la diffusion de la lumière dans la couche de support. Ainsi, le rayonnement de faible intensité lumineuse est absorbé par le colorant de la couche de support et empêche la diffusion de la lumière dans cette couche. On obtient ainsi un pictogramme éclairé de façon nette et ressortant clairement par rapport à la zone l'entourant. One of the aims of the invention is to overcome this drawback by proposing a trim panel of the aforementioned type in which the illumination of the pictogram is made accurately and the image obtained is clear and clear from the area surrounding it. For this purpose, the invention relates to a trim panel of the aforementioned type, wherein the support layer is tinted so as to form a high-pass filter for light from the light source. The coloring of the support layer acting as a high-pass filter makes it possible to filter the low light intensities responsible for the scattering of light in the support layer. Thus, the low light intensity radiation is absorbed by the dye of the support layer and prevents the diffusion of light in this layer. In this way, a pictogram is clearly lit and clearly visible in relation to the surrounding area.
Selon d'autres caractéristiques du panneau de garnissage : - la couche de support est réalisé en matériau polymère chargé en verre et comprenant un colorant ; - le polymère de la couche de support est du polypropylène chargé à 10% en fibres de verre et contenant de l'EPDM, la teneur en colorant étant sensiblement comprise entre 10/0 et 5% ; - le colorant comprend des granulés comprenant des pigments noyés dans une résine ; - le panneau comprend un masque comprenant au moins une ouverture de la forme du pictogramme, ledit masque laissant passer la lumière à travers l'ouverture et bloquant celle-ci autour de l'ouverture, ledit masque étant disposé 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 la couche de support ou entre la couche de support 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 la couche de support ; - le masque est un élément indépendant ; et - la couche de support comprend des moyens de fixation d'un boîtier, la source de lumière étant disposée dans ledit boîtier. According to other characteristics of the trim panel: the support layer is made of glass-filled polymer material and comprising a dye; the polymer of the support layer is polypropylene filled with 10% of glass fibers and containing EPDM, the dye content being substantially between 10/0 and 5%; the dye comprises granules comprising pigments embedded in a resin; the panel comprises a mask comprising at least one opening of the form of the pictogram, said mask allowing the light to pass through the opening and blocking it around the opening, said mask being arranged in the path of passage of the light between the light source and the translucent skin; the mask is disposed between the translucent skin and the support layer or between the support layer 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 support layer; - the mask is an independent element; and - the support layer comprises means for fixing a housing, the light source being disposed in said housing.
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. D'autres aspects et avantages de l'invention apparaîtront à la lecture 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 en coupe d'une partie d'un panneau de garnissage selon l'invention, - la Fig. 2 est une représentation schématique de dessus de la peau montrant la zone formant pictogramme lorsqu'elle est éclairée. Dans la description, on entend par externe ce qui est visible depuis 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 à la Fig. 1, on décrit un panneau de garnissage 1 comprenant une peau translucide 2 et une couche de support 4 disposée contre la surface interne 6 de la peau 2. 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. Other aspects and advantages of the invention will appear on reading the description which follows, given by way of example and with reference to the appended drawings, in which: FIG. 1 is a diagrammatic representation in section of a portion of a trim panel according to the invention; FIG. 2 is a schematic top view of the skin showing the pictogram area when illuminated. In the description, external means what is visible from 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. With reference to FIG. 1, there is described a lining panel 1 comprising a translucent skin 2 and a support layer 4 disposed against the inner surface 6 of the skin 2.
La couche de support 4 est par exemple réalisée en un matériau polymère translucide chargé en verre et adhérant à la peau translucide 2, ladite couche de support étant par exemple surmoulée directement sur la peau 2. Cet ensemble peut être conformé de la façon souhaitée pour s'adapter au garnissage d'un véhicule automobile. La surface externe 8 formée par la peau 2 est par exemple sensiblement plane ou présente des zones en saillie ou en creux, par exemple pour signaler la présence de boutons de commande de fonctions du véhicule sous l'ensemble peau 2 / couche de support 4. Au moins une zone 10 du panneau de garnissage 1 comprend un pictogramme 12 rétroéclairé. Par rétroéclairé, on entend qu'une source de lumière 14 est disposée sous le panneau de garnissage 1 et émet de la lumière selon un faisceau F qui est diffusé dans la peau translucide 2 dans la zone 10. De façon connue, la source de lumière 14 est disposée dans un boîtier 16, appelé boîte à lumière , comprenant une ouverture supérieure 18 recouverte par le panneau de garnissage 1. La source de lumière 14 est par exemple une diode électroluminescente. Selon le mode de réalisation représenté sur la Fig. 1, le boîtier 16 est fixé à la couche de support 4 par des moyens de fixation 20 s'étendant sous la couche de support 4. Les moyens de fixation 20 comprennent par exemple des pattes 22 s'étendant à partir de la surface interne de la couche de support 4 et comprenant des ouvertures de réception de saillies de fixation 24 prévues sur le boîtier 16. Selon un autre mode de réalisation, le boîtier 16 est fixé à un support s'étendant sous le panneau de garnissage. The support layer 4 is for example made of a translucent polymer material loaded with glass and adhering to the translucent skin 2, said support layer being for example overmolded directly on the skin 2. This assembly can be shaped as desired for adapt to the lining of a motor vehicle. The outer surface 8 formed by the 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 assembly 2 / support layer 4. At least one zone 10 of the trim panel 1 comprises a pictogram 12 backlit. By backlit means that a light source 14 is disposed under the lining panel 1 and emits light along a beam F which is diffused in the translucent skin 2 in the zone 10. In known manner, the light source 14 is disposed in a housing 16, called light box, comprising an upper opening 18 covered by the trim panel 1. The light source 14 is for example a light emitting diode. According to the embodiment shown in FIG. 1, the housing 16 is fixed to the support layer 4 by fixing means 20 extending under the support layer 4. The fixing means 20 comprise, for example, tabs 22 extending from the inner surface of the support layer 4 and including fixing projection receiving openings 24 provided on the housing 16. According to another embodiment, the housing 16 is attached to a support extending under the trim panel.
La couche de support 4 est par exemple formée à partir de polypropylène chargé à 10% en fibres de verre et contenant de l'EPDM (Ethylène Propylène Diène Monomère) et comprend un colorant dont la teneur est sensiblement comprise entre 1% et 5%. Selon un mode de réalisation, la teneur en colorant est sensiblement égale à 2%. Le colorant comprend par exemple des granulés comprenant des pigments noyés dans une résine, produit connu sous le nom de masterbatch qui évite d'utiliser des poudres de pigments très polluantes. L'utilisation d'un tel colorant permet de donner la fonction de filtre passe-haut à la couche de support 4. Un tel filtre absorbe le rayonnement de faible intensité de la lumière provenant de la source de lumière 14 et ne laisse passer que le rayonnement de forte intensité. La demanderesse a constaté que la lumière de faible intensité était responsable de la diffusion de la lumière dans la couche de support, ce qui crée un pictogramme flou 12 sur la peau 2. Ainsi, lorsque le colorant absorbe la lumière de faible intensité, la diffusion de la lumière dans la couche de support 4 est empêchée et seule la lumière de forte intensité débouche dans la zone 10 formant pictogramme 12, ce qui forme un pictogramme 12 net et présentant un fort contraste par rapport au reste de la peau, comme représenté sur la Fig. 2. La zone 10 peut être uniformément éclairée ou seulement partiellement de sorte à éclairer une forme particulière de pictogramme 12, comme représenté sur la Fig. 2. Cette forme est par exemple réalisée au moyen d'un masque (non représenté) comprenant au moins une ouverture de la forme du pictogramme 12. 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 14 et la peau translucide 2. Le masque est un élément rapporté ou est imprimé directement sur un élément du panneau de garnissage 1, par exemple par des techniques de tampographie, d'héliographie, d'impression ou de marquage à chaud. Selon divers modes de réalisation, dans le cas d'un masque imprimé, le masque est imprimé sur la face inférieure de la peau 2 ou sur la face inférieure ou la face supérieure de la couche de support 4. The support layer 4 is for example formed from polypropylene filled with 10% glass fibers and containing EPDM (Ethylene Propylene Diene Monomer) and comprises a dye whose content is substantially between 1% and 5%. According to one embodiment, the dye content is substantially equal to 2%. The dye comprises, for example, granules comprising pigments embedded in a resin, a product known under the name of masterbatch which avoids the use of highly polluting pigment powders. The use of such a dye makes it possible to give the function of high-pass filter to the support layer 4. Such a filter absorbs the low-intensity radiation of the light coming from the light source 14 and passes only the high intensity radiation. The Applicant has found that the low intensity light is responsible for the diffusion of light in the support layer, which creates a fuzzy pictogram 12 on the skin 2. Thus, when the dye absorbs light of low intensity, the diffusion light in the support layer 4 is prevented and only the high intensity light emerges in the area 10 forming pictogram 12, which forms a pictogram 12 net and having a high contrast with the rest of the skin, as shown on FIG. Zone 10 may be uniformly illuminated or only partially so as to illuminate a particular form of pictogram 12, as shown in FIG. 2. This form is for example made by means of a mask (not shown) comprising at least one opening of the form of the pictogram 12. This mask passes 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 14 and the translucent skin 2. The mask is an insert or is printed directly on a member of the trim panel 1, for example by pad printing techniques , heliography, printing or hot stamping. According to various embodiments, in the case of a printed mask, the mask is printed on the lower face of the skin 2 or on the lower face or the upper face of the support layer 4.
Dans le cas d'un élément rapporté, le masque est disposé entre la peau 2 et la couche de support 4 ou entre la couche de support 4 et la source de lumière 14, par exemple en recouvrant l'ouverture 18 du boîtier 16. Afin de conférer un aspect ou une couleur particuliers à la peau 2, celle-ci peut être grainée. Afin d'éviter que la lumière passant de l'extérieur vers l'intérieur du panneau de garnissage ne soit réfléchie par la boîte à lumière lorsque le pictogramme n'est pas éclairé, ce qui modifierai l'aspect de la zone 10 par rapport au reste de la peau, le boîtier 16 est réalisé de sorte à absorber la lumière, par exemple en utilisant un matériau noir. Ainsi, seule la lumière provenant de la source de lumière 14 passe par la couche souple 4 et par la peau 2. Le panneau de garnissage décrit ci-dessus permet d'obtenir un pictogramme 12 éclairé de façon nette et sans débordement autour du pictogramme du fait de l'absorption de la lumière de faible intensité par le colorant de la couche de support 4. De plus, la peau présente un aspect uniforme lorsque le pictogramme n'est pas éclairé. In the case of an insert, the mask is disposed between the skin 2 and the support layer 4 or between the support layer 4 and the light source 14, for example by covering the opening 18 of the housing 16. to give a particular appearance or color to the skin 2, it can be grained. In order to prevent the light passing from the outside to the inside of the trim panel from being reflected by the light box when the pictogram is not lit, which will modify the appearance of the zone 10 with respect to rest of the skin, the housing 16 is made to absorb light, for example using a black material. Thus, only the light coming from the light source 14 passes through the flexible layer 4 and through the skin 2. The trim panel described above makes it possible to obtain a pictogram 12 that is clearly illuminated and without overflow around the pictogram of the the absorption of the low-intensity light by the dye of the support layer 4. In addition, the skin has a uniform appearance when the pictogram is not illuminated.
