Description

Dispositif de signalisation lumineuse sur une peau souple et son procédé de fabrication Light-signaling device on a flexible skin and its manufacturing process
La présente invention concerne un dispositif de signalisation lumineuse et son procédé de fabrication .The present invention relates to a light signaling device and its method of manufacture.
L'invention concerne plus précisément la formation d'un dispositif de signalisation lumineuse sur un organe possédant à l ' extérieur une peau souple qui peut être déformée . Par exemple, des éléments de garnissage de compartiments des passagers d'une automobile ont souvent une surface formée par une peau souple disposée sur une mousse elle-même portée par un support rigide. La souplesse de la peau portée par la couche de mousse réduit ou supprime les blessures des passagers en cas de collision, et donne un toucher apprécié.The invention more specifically relates to the formation of a light signaling device on a member having on the outside a flexible skin which can be deformed. For example, passenger compartment trim elements of an automobile often have a surface formed by a flexible skin disposed on a foam itself carried by a rigid support. The softness of the skin on the foam layer reduces or eliminates passenger injury in the event of a collision and gives a nice touch.
On connaît déjà, d'après le document EP-688 701, un organe moulé de module de sac gonflable dans lequel une fenêtre rigide est intégrée par formation d'un insert lors du moulage. Dans une variante de ce document et dans le document DE—35 11 496, une mince souche de peinture est déposée sur une peau souple pour délimiter une "fenêtre" par absence de peinture .It is already known from EP-688 701, a molded airbag module member in which a rigid window is integrated by forming an insert during molding. In a variant of this document and in DE-35 11 496, a thin strain of paint is deposited on a flexible skin to define a "window" by lack of paint.
On connaît aussi, d'après les documents DE-35 11 496, WO 98/11576 et US 2004/095739, un dispositif de commutation muni d'un dispositif de signalisation dont l'organe de commande forme une saillie par rapport à la surface du dispositif dans lequel est intégré le dispositif de commutation.Also known from DE-35 11 496, WO 98/11576 and US 2004/095739, a switching device provided with a signaling device whose control member forms a projection relative to the surface of the device in which the switching device is integrated.
Enfin, les documents US 2005/077154 et DE-43 13 030 décrivent des disposXtrrs—dë^coiuîîπïΛ≡s^^srî^^ay≥n-t^une^pa^EfeiÉ transparente qui n ' est pas souple .Finally, documents US 2005/077154 and DE-43 13 030 disclose disposXtrrs-de coiuîîπïΛ≡s ^ ^^ ^^ Srî ay≥nt ^ a ^ pa ^ EfeiÉ transparent which is not flexible.
Le document US-6 652 128 concerne un dispositif de signalisation lumineuse formé par exemple dans un accoudoir d'automobile. L'accoudoir a une peau souple portée par une couche de mousse et, à l'emplacement d'un organe de commande de lève-vitre, la peau souple est percée de trous formant un motif de transmission de lumière dessinant un logo représentatif de la fonction de levage de vitre ; une source de lumière est placée sous cette partie de la peau.Document US Pat. No. 6,652,128 relates to a light-signaling device formed for example in an automobile armrest. The armrest has a supple skin carried by a layer of foam and, at the location of a window regulator, the flexible skin is pierced with holes forming a light transmission pattern drawing a logo representative of the glass lifting function; a light source is placed under this part of the skin.
Lorsque la source de lumière fonctionne, de la lumière passe par les trous de la peau, si bien qu'un passager est averti de l ' emplacement de l ' organe de commande de lève- vitre. Il peut donc exercer une pression avec un doigt, si bien que l ' organe à commander exécute la manoeuvre voulue .When the light source is working, light passes through the holes in the skin, so that a passenger is warned of the location of the window regulator. It can therefore exert pressure with a finger, so that the organ to be controlled executes the desired maneuver.
Un tel dispositif est commode car il évite les saillies formées par des boutons de manoeuvre de commutateurs, habituellement nécessaires pour la commande des lève-vitre et d'autres accessoires électriques. Cependant, cette disposition a l ' inconvénient de permettre l ' entrée de poussières et de saletés par les trous de la peau, et donc un encrassement de l'organe à commander et même de la source de lumière, provoquant rapidement un défaut de fonctionnement.Such a device is convenient because it avoids the projections formed by switches operating buttons, usually necessary for the control of window lifters and other electrical accessories. However, this arrangement has the disadvantage of allowing the entry of dust and dirt through the holes of the skin, and thus a fouling of the body to be controlled and even of the light source, quickly causing a malfunction.
Pour remédier à cet inconvénient, on peut utiliser la disposition décrite dans le document FR-2 824 510 selon lequel une peau et une couche de mousse d'un complexe sont formées d'un matériau translucide afin qu'un logo éclairé, placé derrière le complexe formé peau-mousse, puisse être observé . Cette disposition a l ' inconvénient de limiter beaucoup la nature de la couche de mousse et celle de la peau, si bien que l ' aspect translucide ou transparent de la peau existe sur l'ensemble de la pièce concernée, qui peut être la planche de bord, à moins qu'un traitement spécifique tel qu'une peinture, rendent des parties opaques. Il est donc souhaitable de pouvoir utiliser d'autres matériaux comme peau souple, notamment des matériaux opaques.To overcome this drawback, it is possible to use the arrangement described in document FR-2 824 510 according to which a skin and a layer of foam of a complex are formed of a translucent material so that an illuminated logo placed behind the complex formed skin-foam, can be observed. This arrangement has the disadvantage of greatly limiting the nature of the foam layer and that of the skin, so that the translucent or transparent appearance of the skin exists on the entire part concerned, which can be the dashboard. , unless a specific treatment such as a painting, render opaque parts. It is therefore desirable to use other materials as soft skin, including opaque materials.
Pour remédier aux inconvénients de la technique antérieure, l'invention concerne un dispositif de signalisation lumineuse dans lequel la peau comporte un complexe de deux couches , l ' une souple et opaque qui est percée de trous formant un motif de transmission de lumière, représentant par exemple un logo évocateur d' un organe commandé , et l ' autre translucide ou transparente, solidarisée à la couche opaque au moins dans la région ayant les trous . De cette manière , les trous ne débouchent pas , et la poussière et les saletés ne peuvent pas parvenir à la source de lumière ou à l ' organe à commander éventuellement placé au-dessous .In order to overcome the drawbacks of the prior art, the invention relates to a light-signaling device in which the skin comprises a complex of two layers, one of which is flexible and opaque and which is pierced with holes forming a light transmission pattern, representing by a logo evocative of a controlled organ, and the other translucent or transparent, secured to the opaque layer at least in the region having the holes. In this way, the holes do not open, and dust and dirt can not reach the light source or the control unit possibly placed below.
Dans des modes de réalisation, la couche translucide ou transparente est souple, et dans d'autres elle est relativement rigide. Dans le premier cas, la couche translucide ou transparente peut avoir une grande étendue , bien au-delà du motif de transmission de lumière, alors que, dans le second cas , il est préférable que la couche translucide ou transparente rigide soit limitée à une partie relativement voisine du motif de transmission de lumière, afin que les propriétés de souplesse de la couche opaque puissent être mises en oeuvre aux limites de la couche rigide .In embodiments, the translucent or transparent layer is flexible, and in others it is relatively rigid. In the first case, the translucent layer or transparent may have a large extent, well beyond the light transmission pattern, while in the second case, it is preferable that the translucent or transparent transparent layer is limited to a relatively adjacent portion of the light transmission pattern so that the flexibility properties of the opaque layer can be implemented at the boundaries of the rigid layer.
Plus précisément, l'invention concerne un dispositif de signalisation lumineuse ayant une ou plusieurs sources de lumière et une peau souple comportant localement un motif de transmission de lumière ; selon l'invention la peau comporte deux couches superposées , les deux couches de la peau sont souples , l ' une des couches étant opaque et l ' autre translucide ou transparente, la couche opaque étant telle que la couche translucide ou transparente lui est solidarisée, le motif de transmission de lumière est formé de trous qui traversent la couche opaque mais ne traversent pas la couche translucide ou transparente, et la couche opaque est disposée plus loin de la source de lumière au moins que la couche translucide ou transparente.More specifically, the invention relates to a light signaling device having one or more light sources and a flexible skin locally having a light transmission pattern; according to the invention the skin comprises two superimposed layers, the two layers of the skin are flexible, one of the layers being opaque and the other translucent or transparent, the opaque layer being such that the translucent or transparent layer is secured thereto, the light transmission pattern is formed by holes which pass through the opaque layer but do not pass through the translucent or transparent layer, and the opaque layer is disposed further away from the light source than at least the translucent or transparent layer.
Dans un mode de réalisation, la couche translucide ou transparente est disposée sur une partie seulement de la couche opaque correspondant à la partie ayant un motif de trous. De préférence, la couche opaque a une épaisseur réduite dans la partie ayant le motif de trous .In one embodiment, the translucent or transparent layer is disposed on only a portion of the opaque layer corresponding to the portion having a pattern of holes. Preferably, the opaque layer has a reduced thickness in the portion having the pattern of holes.
De préférence, la source de lumière au moins est fixée à la couche translucide ou transparente, de sorte que 1 ' effet de signalisation lumineuse est sensiblement constant lors de la déformation de la peau souple. Par exemple, la couche translucide ou transparente forme un logement pour la source de lumière .Preferably, the at least one light source is attached to the translucent or transparent layer, so that the light signaling effect is substantially constant during the deformation of the soft skin. For example, the translucent or transparent layer forms a housing for the light source.
Dans un mode de réalisation, le dispositif comporte en outre un organe destiné à être commandé par une pression exercée sur le motif de la peau, et les deux couches de la peau transmettent la pression à l ' organe destiné à être commandé .In one embodiment, the device further comprises a member to be controlled by a pressure exerted on the pattern of the skin, and the two layers of the skin transmit the pressure to the member to be controlled.
Dans un autre mode de réalisation, le dispositif comporte en outre un organe destiné à être commandé par une pression exercée sur le motif de la peau, la couche translucide ou transparente est sensiblement rigide sur la partie correspondant au motif de la couche opaque , et la déformation de la peau provoque un déplacement de la couche translucide ou transparente pour l'application d'une pression à l ' organe à commander .In another embodiment, the device further comprises a member intended to be controlled by a pressure exerted on the pattern of the skin, the translucent or transparent layer is substantially rigid on the portion corresponding to the pattern of the opaque layer, and the deformation of the skin causes a displacement of the translucent or transparent layer for the application of a pressure to the organ to be controlled.
L'invention concerne aussi un procédé de fabrication d'un dispositif de signalisation lumineuse ayant au moins une source de lumière et une peau souple comportant localement un motif de transmission de lumière ; le procédé comprend la réalisation d'une couche opaque ayant des trous formant un motif de transmission de lumière, la solidari- sation de la partie de couche opaque ayant le motif de transmission de lumière à une couche translucide ou transparente, et le montage d' une source de lumière au moins du côté de la couche translucide ou transparente .The invention also relates to a method of manufacturing a light signaling device having at least one light source and a flexible skin locally having a light transmission pattern; the method comprises making an opaque layer having holes forming a light transmitting pattern, solidifying the opaque layer portion having the light transmitting pattern with a translucent or transparent layer, and mounting the same. a light source at least on the side of the translucent or transparent layer.
De préférence, la réalisation de la couche opaque est effectuée par injection de matière plastique.Preferably, the production of the opaque layer is carried out by injection of plastic material.
L'invention concerne aussi un procédé de fabrication d'un dispositif de signalisation lumineuse ayant au moins une source de lumière et une peau souple comportant localement un motif de transmission de lumière ; le procédé comprend la réalisation d'une peau souple ayant deux couches solidaires superposées , l ' une étant opaque et l ' autre étant translucide ou transparente, la formation d'un motif de trous traversant la couche opaque mais pas une partie au moins de l'épaisseur de la couche translucide ou transparente, et le montage d'une source de lumière du côté de la couche translucide ou transparente, de sorte que la source de lumière est séparée de façon étanche des trous de la couche opaque .The invention also relates to a method of manufacturing a light signaling device having at least one light source and a flexible skin locally having a light transmission pattern; the method comprises producing a flexible skin having two superimposed integral layers, one being opaque and the other being translucent or transparent, forming a pattern of holes passing through the opaque layer but not at least a portion of the the thickness of the translucent or transparent layer, and the mounting of a light source on the translucent or transparent layer side, so that the light source is sealed from the holes of the opaque layer.
De préférence, la formation du motif de trous traversant la couche opaque est réalisée par un faisceau laser.Preferably, the pattern of holes passing through the opaque layer is formed by a laser beam.
D ' autres caractéristiques et avantages de l ' invention seront mieux compris à la lecture de la description qui va suivre d'exemples de réalisation, faite en référence au dessin annexé sur lequel : la figure 1 est une coupe schématique d'un exemple de peau souple d'un dispositif de signalisation lumineuse selon l ' invention ; la figure 2 est un agrandissement d'une partie de la figure 1 dans un exemple de réalisation ; la figure 3 représente une peau dans un autre mode de réalisation de l ' invention ; et la figure 4 représente un dispositif de signalisation lumineuse selon un autre mode de réalisation de l ' invention .Other features and advantages of the invention will be better understood on reading the following description of embodiments, with reference to the appended drawing in which: Figure 1 is a schematic sectional view of an example of flexible skin of a light signaling device according to the invention; Figure 2 is an enlargement of a portion of Figure 1 in an exemplary embodiment; Figure 3 shows a skin in another embodiment of the invention; and FIG. 4 shows a light signaling device according to another embodiment of the invention.
La figure 1 représente en coupe une peau souple d'un dispositif de signalisation lumineuse selon l ' invention . Sur cette figure, la peau souple est formé d'un complexe 10 qui comprend une couche extérieure opaque 12 qui est percée de trous 14 qui forment un motif 16 de transmission de lumière. Une couche transparente et souple 18 est solidarisée à la couche 12. La lumière 20 d'une source lumineuse placée du côté de la couche translucide ou transparente 18 parvient sur le motif de transmission de lumière 16.FIG. 1 represents in section a flexible skin of a light signaling device according to the invention. In this figure, the flexible skin is formed of a complex 10 which comprises an opaque outer layer 12 which is pierced with holes 14 which form a pattern 16 of light transmission. A transparent and flexible layer 18 is secured to the layer 12. The light 20 of a light source placed on the side of the translucent or transparent layer 18 reaches the light transmission pattern 16.
La figure 2 indique sous forme agrandie comment les trous 14 peuvent être formés par un faisceau laser. Il est important que le faisceau laser traverse toute l ' épaisseur de la couche 12 à cause de l'opacité de celle-ci. Les trous peuvent pénétrer ou non dans la couche translucide ou transparente 18, mais sans traverser celle-ci afin que les saletés ou poussières ne puissent pas traverser le complexe 10.Figure 2 shows in enlarged form how the holes 14 may be formed by a laser beam. It is important that the laser beam passes through the entire thickness of the layer 12 because of the opacity thereof. The holes can penetrate or not into the translucent or transparent layer 18, but without passing through it so that dirt or dust can not pass through the complex 10.
La figure 3 représente une variante de l ' invention . Dans celle-ci, le complexe 22 formant la peau comprend une couche 24 qui est souple et opaque, et une couche translucide ou transparente 30 qui est relativement rigide. Cette couche rigide a des picots 26 qui atteignent la surface de la couche opaque 24, de sorte que cette couche opaque a des trous correspondant aux picots 26 et formant un motif 28 de transmission de lumière. La couche translucide ou transparente 30 est solidarisée à la couche opaque 24 uniquement dans une région qui correspond au motif 28 de transmission de lumière. De cette manière, une pression exercée sur le complexe 22 au niveau du motif de transmission de lumière 28 permet, par déformation de la couche souple 24 de part et d'autre de la couche rigide 30, un déplacement en translation de celle-ci qui peut alors venir au contact d'un organe à commander .Figure 3 shows a variant of the invention. In this, the skin complex 22 comprises a layer 24 which is soft and opaque, and a translucent or transparent layer 30 which is relatively rigid. This rigid layer has pins 26 which reach the surface of the opaque layer 24, so that this opaque layer has holes corresponding to the pins 26 and forming a pattern 28 of light transmission. The translucent or transparent layer 30 is secured to the opaque layer 24 only in a region corresponding to the pattern 28 of light transmission. In this way, a pressure exerted on the complex 22 at the light transmission pattern 28 allows, by deformation of the flexible layer 24 of the else of the rigid layer 30, a displacement in translation thereof which can then come into contact with a body to be controlled.
Lors de la fabrication de cette variante, il est avantageux que la couche rigide soit d'abord formée avec les picots, et que la couche opaque 24 soit ensuite formée par injection dans un moule contenant la couche rigide 30.During the manufacture of this variant, it is advantageous that the rigid layer is first formed with the pins, and that the opaque layer 24 is then formed by injection into a mold containing the rigid layer 30.
Dans un mode de réalisation, la source lumineuse peut être solidaire de la couche rigide 30. Par exemple, celle-ci peut former un logement d' une photodiode .In one embodiment, the light source may be integral with the rigid layer 30. For example, the latter may form a housing of a photodiode.
La figure 4 représente une variante dans laquelle une couche transparente et rigide 32 est munie à sa périphérie d'un flasque 34 percé de trous 36. La peau souple et opaque 38 est formée par moulage par injection, si bien qu'elle forme une partie amincie 40 à l'emplacement de la couche translucide ou transparente 32 , et des saillies 42 de rive- tage de la couche rigide 32 sur la peau souple 38.FIG. 4 represents a variant in which a transparent and rigid layer 32 is provided at its periphery with a flange 34 pierced with holes 36. The flexible and opaque skin 38 is formed by injection molding, so that it forms a part thinned 40 at the location of the translucent or transparent layer 32, and projections 42 of shore of the rigid layer 32 on the flexible skin 38.
Les trous du motif de transmission de lumière ne sont pas représentés sur la figure 4. Ils peuvent être réalisés soit par faisceau laser, comme dans le mode de réalisation décrit en référence à la figure 2 , soit directement par moulage lors de l'injection de la couche 38, comme dans le mode de réalisation décrit en référence à la figure 3.The holes of the light transmission pattern are not shown in FIG. 4. They can be made either by laser beam, as in the embodiment described with reference to FIG. 2, or directly by molding during the injection of layer 38, as in the embodiment described with reference to FIG.
La couche opaque peut être d'un type couramment utilisé, par exemple de polyoléfine, de chlorure de polyvinyle, etc., et la couche translucide ou transparente est formée d'un matériau translucide ou transparent, tel qu'une polyoléfine ou un chlorure de polyvinyle non chargé .The opaque layer may be of a commonly used type, for example polyolefin, polyvinyl chloride, etc., and the translucent or transparent layer is formed of a translucent or transparent material, such as a polyolefin or a chloride of polyvinyl chloride. unloaded polyvinyl.
Le motif de transmission de lumière formé par les trous constitue une marque permettant à l'utilisateur de localiser par exemple un interrupteur de lève-vitre placé au-dessous . Ce motif est donc évocateur de l'organe commandé, et se trouve de préférence sur l ' essentiel de la zone de peau sur laquelle peut être exercée la pression de commande. The light transmission pattern formed by the holes is a mark allowing the user to locate for example a window regulator switch placed below. This pattern is therefore evocative of the controlled member, and is preferably on most of the skin area on which the control pressure can be exerted.
