ANTECEDENTES DE LA INVENCIÓN Con el objeto de mejorar el confort del ocupante del vehículo y permitir la personalización del interior del vehículo, una de las tendencias actuales es la incorporación de funciones adicionales a los elementos de revestimiento decorativo ya existentes, como es la iluminación con diversas funciones como la señalización, decoración, etc. BACKGROUND OF THE INVENTION In order to improve the comfort of the occupant of the vehicle and allow customization of the interior of the vehicle, one of the current trends is the incorporation of additional functions to the existing decorative cladding elements, such as lighting with various functions such as signage, decoration, etc.
En algunos casos resulta atractiva la incorporación de iluminación en el revestimiento decorativo de tal forma que los medios de iluminación permanezcan ocultos cuando no actúa la fuente de iluminación. Para ocultar los medios de iluminación en este caso, el recubrimiento decorativo que aporta el acabado estético al revestimiento decorativo, cubre dichos medios de iluminación. In some cases, the incorporation of lighting into the decorative coating is attractive so that the lighting means remain hidden when the light source does not act. To hide the lighting means in this case, the decorative coating that provides the aesthetic finish to the decorative coating covers said lighting means.
Por tanto, para que la luz se transmita a través del recubrimiento decorativo y sea visible en el interior del vehículo cuando actúan los medios de iluminación, dicho recubrimiento decorativo puede ser traslúcido o presentar orificios a través de los cuales se transmite la luz hacia el interior del vehículo. Therefore, so that the light is transmitted through the decorative coating and is visible inside the vehicle when the lighting means act, said decorative coating can be translucent or have holes through which the light is transmitted inwards. vehicle.
Por otro lado, la luz puede transmitirse de forma uniforme a través de una superficie del revestimiento decorativo sin presentar una forma definida, por ejemplo en el caso en el que la luz pase a través de un recubrimiento decorativo traslúcido, o puede transmitirse de forma localizada, a través de zonas concretas del recubrimiento decorativo, presentando una forma definida, por ejemplo en el caso en el que se utilice una máscara que impide el paso de la luz de forma selectiva. On the other hand, the light can be transmitted uniformly across a surface of the decorative lining without having a defined shape, for example in the case where the light passes to through a translucent decorative coating, or it can be transmitted locally, through specific areas of the decorative coating, presenting a defined shape, for example in the case where a mask is used that prevents the passage of light selectively .
Una máscara está formada por una combinación de zonas que permiten el paso de la luz y de zonas que impiden el paso de la luz. Para ello, una máscara normalmente está formada por un elemento opaco que comprende zonas que impiden la transmisión de la luz emitida por los medios de iluminación, y zonas recortadas o perforadas que permiten el paso de la luz. A mask is formed by a combination of areas that allow the passage of light and areas that prevent the passage of light. For this, a mask is normally formed by an opaque element that includes zones that prevent the transmission of the light emitted by the lighting means, and cut or perforated areas that allow the light to pass through.
Mediante la combinación de las zonas de la máscara que permiten el paso de la luz y las zonas de la máscara que no lo permiten, se configura un motivo predefinido que puede tener diferentes funciones, como pueden ser las de decoración, señalización, información, etc . By combining the zones of the mask that allow the passage of light and the zones of the mask that do not allow it, a predefined motif is configured that can have different functions, such as decoration, signage, information, etc. .
Por un lado dicha máscara se puede localizar entre los medios de iluminación y la cara vista de un recubrimiento decorativo traslúcido. De esta forma, cuando los medios de iluminación presentan un estado apagado, el motivo no es visible para el ocupante del vehículo . Por otro lado, en el caso en el que las zonas recortadas o perforadas de la máscara alcancen la cara vista del recubrimiento decorativo, el motivo es visible además cuando los medios de iluminación se encuentran en un estado apagado. On the one hand, said mask can be located between the lighting means and the exposed face of a translucent decorative coating. Thus, when the lighting means have an off state, the motive is not visible to the occupant of the vehicle. On the other hand, in the case where the cut or perforated areas of the mask reach the visible face of the decorative coating, the motif is visible also when the lighting means are in an off state.
Dicha máscara se puede llevar a cabo por ejemplo mediante la eliminación de una porción del elemento opaco de acuerdo a la forma predefinida del motivo, con el fin de permitir el paso de la luz a través de dichas zonas eliminadas. Dicha eliminación de las porciones del elemento opaco que configuran las zonas que permiten el paso de la luz puede ser completa, o puede ser parcial mediante la realización de pequeños orificios en el elemento opaco que permitan el paso de la luz a través de los mismos. Said mask can be carried out, for example, by removing a portion of the opaque element according to the predefined shape of the motif, in order to allow light to pass through said eliminated areas. Said elimination of the portions of the opaque element that make up the zones that allow the passage of light can be complete, or it can be partial by making small holes in the opaque element that allow the passage of light through them.
Para el caso en el que el motivo se configure mediante orificios, las posiciones de éstos pueden seguir una distribución regular o una distribución irregular. For the case in which the motif is configured by holes, their positions may follow a regular distribution or an irregular distribution.
Se conocen algunos ejemplos alejados del objeto de la invención mostrados en los documentos DE4209105 y EP2681056 en los que la distribución es de tipo regular, donde dicha regularidad está definida por la distribución del conjunto de orificios de acuerdo a una sucesión de lineas rectas paralelas entre si, de manera que cada uno de los orificios que forma parte de la distribución es equidistante respecto de otros cuatro orificios que forman parte de dicha distribución. Some examples far from the object of the invention shown in documents DE4209105 and EP2681056 are known in which the distribution is of the regular type, where said regularity is defined by the distribution of the set of holes according to a succession of straight lines parallel to each other. , so that each of the holes that is part of the distribution is equidistant from other four holes that are part of said distribution.
En estos casos en los que la distribución de orificios es regular, se plantea un problema para definir el contorno de las zonas que presentan geometrías complejas tales como las que comprenden contornos curvos, ya que no es posible la presencia de orificios de una forma uniforme a lo largo del contorno de dicha zona de acuerdo a una ordenación de los orificios según dicha distribución regular. In these cases in which the distribution of holes is regular, a problem arises to define the contour of areas that present complex geometries such as those that comprise curved contours, since the presence of holes of a uniform shape along the contour of said area of agreement is not possible to an arrangement of the holes according to said regular distribution.
Esto tiene como consecuencia la presencia de discontinuidades en dicho contorno que dificultan una visualización nítida de la forma definida por dicha zona, es decir un contorno bien definido. This results in the presence of discontinuities in said contour that make clear visualization of the shape defined by said area difficult, that is, a well defined contour.
En el caso en el que la distribución sea de tipo irregular y para el caso particular de revestimientos decorativos luminosos para vehículos como el de la invención, se conocen los documentos JP59011934 o US20140119038. El primero de ellos, JP59011934, describe un revestimiento de techo luminoso para vehículo automóvil que comprende un sándwich formado por un soporte estructural, unos medios de iluminación distribuida que comprenden una guía de luz plana en combinación con una fuente de luz y un recubrimiento decorativo visible desde el interior del vehículo que cubre dichos medios de iluminación distribuida. In the case where the distribution is of an irregular type and for the particular case of light decorative coatings for vehicles such as that of the invention, documents JP59011934 or US20140119038 are known. The first one, JP59011934, describes a luminous roof covering for a motor vehicle comprising a sandwich formed by a structural support, distributed lighting means comprising a flat light guide in combination with a light source and a visible decorative coating. from inside the vehicle covering said distributed lighting means.
En este caso, el recubrimiento decorativo presenta un conjunto de orificios que alcanzan la guía de luz con el objeto de transmitir la luz procedente de los medios de iluminación y que son visibles desde el interior del vehículo. In this case, the decorative coating has a set of holes that reach the light guide in order to transmit the light coming from the lighting means and that are visible from the vehicle interior
En este caso, los orificios aparentemente se distribuyen de una forma aleatoria a lo largo de toda la superficie del recubrimiento decorativo, permitiendo proyectar bandas de luz en las zonas del guarnecido dónde existe una correspondencia entre los orificios y la fuente de iluminación distribuida. Por tanto en este caso, el motivo luminoso se encuentra definido por la forma de la guía de luz. In this case, the holes are apparently distributed randomly along the entire surface of the decorative covering, allowing light bands to be projected in the areas of the trim where there is a correspondence between the holes and the distributed light source. Therefore, in this case, the light motif is defined by the shape of the light guide.
El segundo de los documentos citados, US20140119038, describe un revestimiento decorativo luminoso para vehículo automóvil que comprende una lámina perforada localmente preferentemente de material metálico, que cubre unos medios de iluminación distribuida . The second of the cited documents, US20140119038, discloses a luminous decorative coating for a motor vehicle comprising a locally perforated sheet preferably of metallic material, which covers distributed lighting means.
En este caso, la lámina perforada está formada por un conjunto de orificios que definen un motivo luminoso. Dicho motivo puede comprender números, letras u otros diseños. In this case, the perforated sheet is formed by a set of holes that define a luminous motif. Said motif may include numbers, letters or other designs.
Por otro lado la distribución de los orificios puede ser regular o irregular. Sin embargo en la descripción de la invención no se especifica una forma concreta para definir dicha distribución de manera que por un lado permita la obtención de un motivo bien definido a través de su contorno, y por otro lado que permita un buen grado de uniformidad de luz. On the other hand the distribution of the holes can be regular or irregular. However, in the description of the invention a specific way is not specified to define said distribution so that on the one hand it allows obtaining a well defined motif through its contour, and on the other hand it allows a good degree of uniformity of light.
A la vista de los documentos del estado de la técnica descritos mas arriba, el uso de pequeños orificios para definir un motivo luminoso que se extiende de acuerdo a un diseño determinado a lo largo de una superficie de un elemento opaco, plantea un doble problema no resuelto a la vista de los mismos para la obtención de un motivo luminoso. In view of the documents of the state of the technique described above, the use of small holes to define a luminous motif that extends according to a particular design along a surface of an opaque element, poses a double problem not solved in view of them for obtaining of a luminous motif.
El primero de ellos relativo a la identificación de un motivo luminoso bien definido a través de su contorno, es decir un motivo nítidamente definido. The first of these is related to the identification of a well-defined luminous motif through its contour, that is, a sharply defined motif.
El segundo de ellos relativo a conseguir áreas de luz distribuidas con un buen grado de uniformidad. The second one related to achieving distributed light areas with a good degree of uniformity.
Por tanto, mediante la resolución simultánea de ambos problemas se consigue obtener un efecto luminoso semejante al que ofrecería la obtención del motivo mediante la completa eliminación de la porción del elemento opaco que configura dicho motivo. Therefore, by simultaneously solving both problems, a light effect similar to that offered by obtaining the motif is achieved by completely eliminating the portion of the opaque element that configures said motif.
Por tanto, a la vista de lo anterior, la presente invención se refiere a un revestimiento decorativo con motivo luminoso para interior de vehículo automóvil, donde dicho revestimiento decorativo comprende un recubrimiento decorativo donde se configura un motivo luminoso que comprende al menos un área luminosa, donde dicho recubrimiento decorativo comprende al menos una capa opaca perforada, en correspondencia con el área luminosa, que comprende un conjunto de orificios distribuidos según un conjunto de reglas que permiten por un lado una buena definición del contorno del área luminosa permitiendo identificar visualmente dicha área luminosa de una forma nítida a través de su contorno bien definido, y por otro lado, un área luminosa con un buen grado de uniformidad. Therefore, in view of the foregoing, the present invention relates to a decorative lining with a light motif for the interior of a motor vehicle, where said decorative lining comprises a decorative lining where a light motif is configured comprising at least one light area, wherein said decorative coating comprises at least one perforated opaque layer, in correspondence with the luminous area, which comprises a set of holes distributed according to a set of rules that allow on the one hand a good definition of the contour of the luminous area allowing to visually identify said luminous area in a clear way through its well defined contour, and on the other hand, a luminous area with a good degree of uniformity.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención, por tanto, se refiere a un revestimiento decorativo con motivo luminoso para interior de vehículo automóvil que comprende: The present invention, therefore, relates to a decorative lining with a light motif for the interior of a motor vehicle comprising:
• un recubrimiento decorativo donde se configura un motivo luminoso y que comprende al menos una capa opaca,  • a decorative covering where a luminous motif is configured and comprising at least one opaque layer,
donde el motivo luminoso presenta al menos un área luminosa delimitada por un contorno y donde la capa opaca comprende un conjunto de orificios distribuidos en correspondencia con dicha área luminosa,  where the luminous motif has at least one luminous area bounded by an outline and where the opaque layer comprises a set of holes distributed in correspondence with said luminous area,
• y unos medios de iluminación distribuida en correspondencia al menos con el área luminosa, donde los medios de iluminación distribuida están cubiertos por la capa opaca,  • and distributed lighting means in correspondence with at least the light area, where the distributed lighting means are covered by the opaque layer,
de forma que los orificios permiten el paso de la luz procedente de los medios de iluminación distribuida hacia el interior del vehículo automóvil , caracterizado porque:  so that the holes allow the passage of light from distributed lighting means into the interior of the motor vehicle, characterized in that:
• el conjunto de orificios distribuidos comprende al menos nueve orificios, • the set of distributed holes comprises at least nine holes,
• el contorno que delimita el área luminosa está definido por una linea poligonal cerrada en dónde cada vértice de dicha linea poligonal coincide con el baricentro de un orificio del conjunto de orificios distribuidos, • the outline that delimits the light area is defined by a closed polygonal line where each vertex of said polygonal line coincides with the barycenter of a hole in the set of distributed holes,
· las posiciones de los orificios que forman el conjunto de orificios distribuidos no siguen una distribución regular,  · The positions of the holes that make up the set of distributed holes do not follow a regular distribution,
• cada uno de los orificios que forma parte del conjunto de orificios distribuidos tiene una dimensión máxima di comprendida en el intervalo entre 0,5 y 4 rom,  • each of the holes that is part of the set of distributed holes has a maximum dimension of between 0.5 and 4 rom,
• entre cualquier par de orificios del conjunto de orificios distribuidos existe una distancia de separación d2 ≥ 1,5 rom,  • there is a separation distance d2 ≥ 1.5 rom between any pair of holes in the distributed hole set,
· para cualquier orificio del conjunto de orificios distribuidos, existen al menos otros tres tal que las respectivas distancias de separación entre dicho orificio y cada uno de los otros tres orificios, d' 3, d" 3 y d'" 3, son tales que d' 3 2 x d2, d" 3≤ 2 x d2 y d" ' 3≤ 2 x d2. For any hole in the set of distributed holes, there are at least three others such that the respective separation distances between said hole and each of the other three holes, d ' 3 , d " 3 and d '" 3 , are such that d ' 3 2 x d2, d " 3 ≤ 2 x d2 and d "' 3 ≤ 2 x d2.
Los medios de iluminación distribuida se refieren a la utilización de un dispositivo luminoso que emite una luz uniformemente distribuida a lo largo de una superficie, bien porque la propia fuente de luz ofrece una distribución uniforme de la luz como por ejemplo en el caso de una lámina electroluminiscente o de un OLED, o bien porque se utiliza una o varias fuentes de luz que emiten luz puntual en combinación con una guia de luz que permite la distribución uniforme de la luz emitida por dichas fuentes de luz puntuales. Por distribución regular, se entiende un conjunto de orificios distribuidos de acuerdo a una sucesión de lineas rectas paralelas entre si, de manera que cada uno de los orificios que forma parte del conjunto de orificios distribuidos es equidistante respecto de otros cuatro orificios que forman parte de dicho conjunto de orificios distribuidos. La distancia de separación entre dos orificios se refiere a la distancia de separación mínima que hay entre los perímetros correspondientes de dichos orificios . La definición del contorno del área luminosa a través de una línea poligonal cerrada en dónde cada vértice de dicha línea poligonal coincide con el baricentro de un orificio del conjunto de orificios distribuidos, permite la identificación de un área luminosa bien definida sin la necesidad de perfilar dicho contorno por ejemplo mediante la utilización de líneas continuas que delimiten un área que después se rellena mediante orificios. Por otro lado, la combinación de las dimensiones de los orificios y de la distribución de dichos orificios definida a través de las distancias máximas y mínimas de separación entre contornos de orificios, permite crear un reparto uniforme de la luz a través de orificios, a lo largo del área luminosa que forma parte del motivo luminoso. Esto tiene como consecuencia que el ocupante del vehículo perciba una iluminación continua o uniforme a lo largo del área luminosa Distributed lighting means refer to the use of a luminous device that emits a uniformly distributed light along a surface, either because the light source itself offers a uniform distribution of light such as in the case of a sheet electroluminescent or an OLED, or because one or more light sources are used that emit point light in combination with a light guide that allows the uniform distribution of the light emitted by said point light sources. Regular distribution means a set of holes distributed according to a succession of straight lines parallel to each other, so that each of the holes that is part of the set of distributed holes is equidistant from other four holes that are part of said set of distributed holes. The separation distance between two holes refers to the minimum separation distance between the corresponding perimeters of said holes. The definition of the contour of the light area through a closed polygonal line where each vertex of said polygonal line coincides with the barycenter of a hole in the set of distributed holes, allows the identification of a well-defined light area without the need to profile said contour for example by using continuous lines that delimit an area that is then filled by holes. On the other hand, the combination of the dimensions of the holes and the distribution of said holes defined through the maximum and minimum separation distances between hole contours, allows to create a uniform distribution of the light through holes, at along the luminous area that is part of the luminous motif. This results in the vehicle occupant perceiving continuous lighting or uniform along the luminous area
Por otro lado, el conjunto de los orificios distribuidos de la invención permite adaptarse a distintas geometrías de las áreas luminosas que forman parte de un motivo luminoso y que estén formadas tanto por líneas rectas como curvas, asegurando tanto la distribución uniforme de la luz en dichas áreas, como la obtención de un contorno bien definido, mediante la aplicación de las reglas que definen la forma de distribuir los orificios. On the other hand, the set of distributed holes of the invention allows to adapt to different geometries of the luminous areas that are part of a luminous motif and that are formed by both straight and curved lines, ensuring both the uniform distribution of light in said areas, such as obtaining a well-defined contour, by applying the rules that define how to distribute the holes.

En una realización particular de la invención, los medios de iluminación distribuida (3) comprenden al menos un LED (3.2) que genera luz (3.2.1) en combinación con una guia de luz (3.2) que distribuye dicha luz (3.2.1) y la transmite hacia el interior del vehículo a través del recubrimiento decorativo (2) que permite la configuración de al menos un área luminosa (6.2, 6.3, 60.2) . In a particular embodiment of the invention, the distributed lighting means (3) comprise at least one LED (3.2) that generates light (3.2.1) in combination with a light guide (3.2) that distributes said light (3.2.1 ) and transmits it into the vehicle through the decorative covering (2) that allows the configuration of at least one light area (6.2, 6.3, 60.2).
Opcionalmente, dichos medios de iluminación distribuida (3) pueden comprender un elemento electroluminiscente o un OLED en correspondencia al menos con el área luminosa (6.2, 6.3, 60.2) . Optionally, said distributed lighting means (3) may comprise an electroluminescent element or an OLED corresponding to at least the light area (6.2, 6.3, 60.2).
Por otro lado la al menos un área luminosa (6.2, 6.3, 60.2) que forma parte del motivo luminoso (5), está delimitada por un contorno (6.1, 60.1) . On the other hand, the at least one light area (6.2, 6.3, 60.2) that is part of the light motif (5), is delimited by an outline (6.1, 60.1).
Cómo se ha dicho más arriba, al menos una de las áreas luminosas (6.2, 6.3, 60.2) definidas en el motivo está formada por un conjunto de orificios (2.1.1) distribuidos de acuerdo a la invención. As stated above, at least one of the luminous areas (6.2, 6.3, 60.2) defined in the motif is formed by a set of holes (2.1.1) distributed according to the invention.
Cómo se puede ver en la figura 4A dónde se muestra un ejemplo particular de motivo luminoso (5), éste está formado por tres zonas luminosas diferenciadas, una primera zona luminosa en correspondencia con los pétalos (6) de la flor, una segunda zona luminosa en correspondencia con el tallo (60) de la flor y una tercera zona luminosa en correspondencia con las hojas (600) de la flor. As can be seen in Figure 4A where a particular example of a luminous motif (5) is shown, it is formed by three differentiated luminous zones, a first luminous zone corresponding to the petals (6) of the flower, a second luminous zone in correspondence with the stem (60) of the flower and a third luminous zone in correspondence with the leaves (600) of the flower.
Particularmente las primera y segunda zonas luminosas presentan áreas luminosas (6.2, 6.3, 60.2) que comprenden conjuntos de orificios (2.1.1) distribuidos de acuerdo a la invención. Más concretamente, la primera zona luminosa en correspondencia con los pétalos (6) de la flor presenta una primera área luminosa (6.2) y una segunda área luminosa (6.3), y la segunda zona luminosa en correspondencia con el tallo (60) de la flor presenta una tercera área luminosa (60.2) . Particularly, the first and second light zones have luminous areas (6.2, 6.3, 60.2) that comprise sets of holes (2.1.1) distributed according to the invention. More specifically, the first luminous zone in correspondence with the petals (6) of the flower has a first luminous area (6.2) and a second luminous area (6.3), and the second luminous zone in correspondence with the stem (60) of the flower presents a third luminous area (60.2).
Dichas áreas luminosas (6.2, 6.3 y 60.2) son capaces de emitir luz distribuida de una manera uniforme, a través de conjuntos de orificios (2.1.1) distribuidos particulares, que siguen un conjunto de reglas que se explican en detalle más adelante. Said luminous areas (6.2, 6.3 and 60.2) are capable of emitting distributed light in a uniform manner, through sets of particular distributed holes (2.1.1), which follow a set of rules that are explained in detail below.
En cuanto a la tercera zona luminosa en correspondencia con las hojas (600) de la flor, ésta está formada por orificios que siguen lineas continuas que perfilan el contorno de las hojas (600) de la flor a través de las cuales pasa la luz. Por tanto la tercera zona luminosa en correspondencia con las hojas (600) de la flor, es capaz de emitir luz continua que se extiende solamente a lo largo de lineas y no a lo largo de toda la superficie que forma dicha zona como en el caso de las áreas luminosas (6.2, 6.3 y 60.2) definidas más arriba. As for the third light zone in correspondence with the leaves (600) of the flower, it is formed by holes that follow continuous lines that outline the outline of the leaves (600) of the flower through which the light passes. Therefore the third luminous zone in correspondence with the leaves (600) of the flower, is capable of emitting continuous light that extends only along lines and not along the entire surface that forms said zone as in the case of the luminous areas (6.2, 6.3 and 60.2) defined above.
Finalmente el motivo luminoso (5) puede comprender una cuarta zona no luminosa (7) que define la zona central de la flor y que se distingue, bien por la ausencia de orificios (2.1.1) en el caso de la realización mostrada en la figura 3A, o bien por el contraste de iluminación existente con respecto a la primera zona luminosa cuando actúan los medios de iluminación distribuida (3) en el caso de la realización mostrada en la figura 3B. Una vez hecha la distinción entre las zonas luminosas y las áreas luminosas (6.2, 6.3, 60.2), siendo estas últimas las que comprenden un conjunto de orificios (2.1.1) distribuidos de acuerdo a la invención, a continuación se describen las reglas que definen la forma de distribuir dicho conjunto de orificios (2.1.1) distribuidos. Finally the light motif (5) can comprise a fourth non-luminous zone (7) that defines the central zone of the flower and which is distinguished, either by the absence of holes (2.1.1) in the case of the embodiment shown in Figure 3A, or by contrast of existing lighting with respect to the first light zone when the distributed lighting means (3) act in the case of the embodiment shown in Figure 3B. Once the distinction has been made between the light zones and the light areas (6.2, 6.3, 60.2), the latter being those comprising a set of holes (2.1.1) distributed according to the invention, the rules that they define the way to distribute said set of holes (2.1.1) distributed.
En primer lugar un área luminosa (6.2, 6.3, 60.2) de acuerdo a la invención está delimitada por un contorno (6.1, 60.1) que encierra un conjunto de orificios (2.1.1) distribuidos de acuerdo a las siguientes reglas: el conjunto de orificios (2.1.1) distribuidos comprende al menos nueve orificios (2.1.1), First, a luminous area (6.2, 6.3, 60.2) according to the invention is delimited by an outline (6.1, 60.1) that encloses a set of holes (2.1.1) distributed according to the following rules: the set of distributed holes (2.1.1) comprises at least nine holes (2.1.1),
el contorno (6.1, 60.1) que delimita el área luminosa (6.2, 6.3, 60.2) está definido por una linea poligonal (6.1.1) cerrada, representada en la figura 4B mediante una linea discontinua, en dónde cada vértice de dicha linea poligonal (6.1.1) coincide con el baricentro (6.1.2) de un orificio (2.1.1) del conjunto de orificios (2.1.1) distribuidos. Esta característica permite asegurar la definición de las áreas luminosas (6.2, 6.3, 60.2) de una forma nítida, ya que permite definir unas áreas luminosas (6.2, 6.3, 60.2) cuyos contornos se encuentran bien definidos. The contour (6.1, 60.1) that delimits the light area (6.2, 6.3, 60.2) is defined by a closed polygonal line (6.1.1), represented in Figure 4B by a dashed line, where each vertex of said polygonal line (6.1.1) matches the barycenter (6.1.2) of a hole (2.1.1) of the set of holes (2.1.1) distributed. This characteristic ensures the definition of the luminous areas (6.2, 6.3, 60.2) in a clear way, since it allows defining some luminous areas (6.2, 6.3, 60.2) whose contours are well defined.
las posiciones de los orificios (2.1.1) que forman el conjunto de orificios (2.1.1) distribuidos no siguen una distribución regular, es decir, no se distribuyen de acuerdo a una sucesión de líneas rectas paralelas entre sí, de manera que cada uno de los orificios que forma parte del conjunto de orificios (2.1.1) distribuidos, es equidistante respecto de otros cuatro orificios que forman parte de dicho conjunto de orificios (2.1.1) distribuidos . the positions of the holes (2.1.1) that form the set of distributed holes (2.1.1) do not follow a regular distribution, that is, they are not distributed according to a succession of straight lines parallel to each other, so that each one of the holes that is part of the set of holes (2.1.1) distributed, is equidistant from other four holes that are part of said set of holes (2.1.1) distributed.
Esta regla permite adaptar el conjunto de orificios (2.1.1) distribuidos a diferentes geometrías especialmente, en el caso en el que éstas presenten curvaturas.  This rule allows adapting the set of holes (2.1.1) distributed to different geometries especially, in the case where they present curvatures.
Cada uno de los orificios (2.1.1) que forma parte del conjunto de orificios (2.1.1) distribuidos tiene una dimensión máxima di comprendida en el intervalo entre un valor mínimo 0,5 y un valor máximo 4 rom . En este caso, el valor mínimo del intervalo viene condicionado por aquel que permita la transmisión de una cantidad de luz suficiente para que sea apreciable desde la cara vista del recubrimiento decorativo (2) teniendo en cuenta los materiales que forman dicho recubrimiento decorativo (2) y las condiciones de luz ambiente en el interior del vehículo. En cuanto al valor máximo vendrá definido por, y por tanto dependerá de, la dimensión del área luminosa (6.2, 6.3, 60.2), en combinación con la distancia a la que habitualmente un ocupante del vehículo se encuentra del revestimiento decorativo en el que se sitúa dicha área luminosa (6.2, 6.3, 60.2), con el objeto de que dicho ocupante sea capaz de visualizar el área luminosa (6.2, 6.3, 60.2) de forma nítida, es decir, de forma que dicho ocupante sea capaz de visualizar el contorno (6.1, 60.1) del área luminosa (6.2, 6.3, 60.2) bien definido permitiéndole una correcta identificación de la forma de dicha área luminosa (6.2, 6.3, 60.2) . Each of the holes (2.1.1) that is part of the set of distributed holes (2.1.1) has a maximum dimension in the range between a minimum value 0.5 and a maximum value 4 rom. In this case, the minimum value of the interval is conditioned by that which allows the transmission of a sufficient amount of light to be appreciable from the face of the decorative coating (2) taking into account the materials that form said decorative coating (2) and ambient light conditions inside the vehicle. As for the maximum value It will be defined by, and therefore will depend on, the dimension of the luminous area (6.2, 6.3, 60.2), in combination with the distance at which usually an occupant of the vehicle is located from the decorative covering in which said luminous area is located ( 6.2, 6.3, 60.2), so that said occupant is able to visualize the light area (6.2, 6.3, 60.2) clearly, that is, so that said occupant is able to visualize the contour (6.1, 60.1 ) of the luminous area (6.2, 6.3, 60.2) well defined allowing a correct identification of the shape of said luminous area (6.2, 6.3, 60.2).
Entre cualquier par de orificios (2.1.1) del conjunto de orificios (2.1.1) distribuidos, existe una distancia de separación entre dos orificiosBetween any pair of holes (2.1.1) of the set of holes (2.1.1) distributed, there is a separation distance between two holes
(2.1.1) d2 ≥ l,5mm, dónde dicha distancia de separación se corresponde con la mínima separación que hay entre los perímetros de dos orificios(2.1.1) d2 ≥ l, 5mm, where said separation distance corresponds to the minimum separation between the two hole perimeters
(2.1.1) . Dicha distancia de separación mínima entre los perímetros de dos orificios (2.1.1) definida por esta regla, está condicionada por la distancia que necesariamente debe de existir entre dos orificios (2.1.1) teniendo en cuenta las tolerancias del proceso de fabricación de dichos orificios (2.1.1), tal que dicha distancia permita la realización de orificios (2.1.1) independientes unos de otros evitando la unión no deseada de un orificio (2.1.1) con respecto a otro contiguo, y por la distancia de separación que debe de existir entre dos orificios (2.1.1) tal que garantice una cantidad de material suficiente entre los mismos que asegure la durabilidad del revestimiento decorativo ( 1 ) . (2.1.1). Said minimum separation distance between the perimeters of two holes (2.1.1) defined by this rule, is conditioned by the distance that must necessarily exist between two holes (2.1.1) taking into account the tolerances of the manufacturing process of said holes (2.1.1), such that said distance allows the realization of holes (2.1.1) independent of each other avoiding the unwanted union of a hole (2.1.1) with respect to another contiguous one, and by the separation distance that must exist between two holes (2.1.1) such that it guarantees a sufficient amount of material between them to ensure the durability of the decorative coating (1).
• Para cualquier orificio (2.1.1) del conjunto de orificios (2.1.1) distribuidos, existen al menos otros tres orificios (2.1.1) tal que las respectivas distancias de separación entre dicho orificio (2.1.1) y cada uno de los otros tres orificios (2.1.1), d' 3, d" 3 y d'" 3, son tales que d' 3 ≤ 2 x d2, d 3 ≤ 2 x d2 y d 3 ≤ 2 x d2. De manera que cada una de las distancias de separación d' 3, d" 3 y d 3, siempre y cuando cumplan la condición impuesta, pueden ser iguales entre ellas o diferentes. Dicha distancia de separación máxima de un orificio (2.1.1) con al menos otros tres definida por esta regla, permite asegurar la uniformidad de la distribución del conjunto de orificios (2.1.1) distribuidos, de manera que el ocupante del vehículo sea capaz de percibir un efecto de iluminación uniforme a lo largo de la superficie que forma el área luminosa (6.2, 6.3,• For any hole (2.1.1) of the set of holes (2.1.1) distributed, there are at least three other holes (2.1.1) such that the respective separation distances between said hole (2.1.1) and each of the other three holes (2.1.1), d ' 3 , d " 3 yd '" 3 , are such that d ' 3 ≤ 2 x d2, d 3 ≤ 2 x d2 and d 3 ≤ 2 x d2. So that each of the separation distances d ' 3 , d " 3 and d 3, as long as they meet the imposed condition, can be equal to each other or different. Said maximum separation distance of a hole (2.1.1) with at least three others defined by this rule, ensure the uniformity of the distribution of the set of holes (2.1.1) distributed, so that the occupant of the vehicle is able to perceive a uniform lighting effect along the surface that form the light area (6.2, 6.3,
60.2) . 60.2).
Los orificios (2.1.1) que forman el conjunto de orificios (2.1.1) distribuidos de la invención, pueden presentar por ejemplo una forma circular, elíptica, poligonal, etc., pudiendo ser a su vez regulares o irregulares . The holes (2.1.1) that form the set of distributed holes (2.1.1) of the invention can, for example, have a circular, elliptical, polygonal shape, etc., which can be regular or irregular.
Por otro lado, los orificios (2.1.1) que forman el conjunto de orificios (2.1.1) distribuidos de la invención, pueden ser iguales o diferentes entre sí, siempre y cuando se cumpla la regla que establece que la dimensión máxima di de dichos orificios (2.1.1) se encuentre en el intervalo entre 0,5 y 4 rom . On the other hand, the holes (2.1.1) that form the set of distributed holes (2.1.1) of the invention can be the same or different from each other, as long as the rule that establishes that the maximum dimension of said holes (2.1.1) is in the range between 0.5 and 4 rom.
Según una realización de la invención al menos el 80% de los orificios (2.1.1) se distribuyen formando hileras (8) de al menos tres orificios (2.1.1) cada una, dónde los orificios (2.1.1) extremos de cada una de las hileras (8) se sitúan en el contorno (6.1) del área luminosa (6.2, 6.3, 60.2) . According to an embodiment of the invention at least 80% of the holes (2.1.1) are distributed forming rows (8) of at least three holes (2.1.1) each, where the holes (2.1.1) ends of each one of the rows (8) are located in the contour (6.1) of the light area (6.2, 6.3, 60.2).
Dichas hileras (8) se pueden extender sobre lineas rectas, como se muestra en el caso de la segunda área luminosa (6.3), o sobre lineas curvas, como se muestra en el caso de la primera y tercera áreas luminosas (6.2, 60.2) . Said rows (8) can be extended on straight lines, as shown in the case of the second light area (6.3), or on curved lines, as shown in the case of the first and third light areas (6.2, 60.2) .
Por tanto, un motivo luminoso (5) puede comprender varias áreas luminosas (6.2, 6.3, 60.2) que presenten conjuntos de orificios (2.1.1) distribuidos de acuerdo a la invención iguales, o diferentes entre si. Therefore, a luminous motif (5) can comprise several luminous areas (6.2, 6.3, 60.2) that have sets of holes (2.1.1) distributed according to the invention the same, or different from each other.
Dependiendo de la complejidad del área luminosa a iluminar a través del conjunto de orificios (2.1.1) distribuidos de la invención, y con el objeto se asegurar una iluminación uniforme a lo largo del área luminosa (6.2, 6.3, 60.2), es posible que en la realización particular en la que los orificios (2.1.1) se distribuyen en hileras (8), sea necesario que entre dos hileras (8) consecutivas se intercalen orificios (2.1.1) de forma aleatoria no formando hileras como las definidas más arriba, es decir, hileras (8) de al menos tres orificios (2.1.1) cada una dónde los orificios (2.1.1) extremos de cada una de las hileras (8) se sitúan en el contorno (6.1, 60.1) del área luminosa (6.2, 6.3, 60.2) . Para ilustrar lo anterior, se muestra la tercera área luminosa (60.2) dónde el conjunto de orificios (2.1.1) distribuidos comprende hileras (8) curvas y orificios intercalados de manera aleatoria (60.3) entre dos hileras (8) consecutivas. Depending on the complexity of the light area to be illuminated through the set of holes (2.1.1) distributed of the invention, and with the object to ensure uniform illumination along the light area (6.2, 6.3, 60.2), it is possible that in the particular embodiment in which the holes (2.1.1) are distributed in rows (8), it is necessary that between two consecutive rows (8) holes are interleaved (2.1.1) randomly not forming rows as defined above, that is, rows (8) of at least three holes (2.1.1) each where the holes (2.1.1) ends of each of the rows (8) are located in the contour (6.1, 60.1) of the light area (6.2, 6.3, 60.2). To illustrate the above, the third light area (60.2) is shown where the set of distributed holes (2.1.1) comprises rows (8) curves and randomly intercalated holes (60.3) between two consecutive rows (8).
