Abstract

An emblem arrangement for a motor vehicle has an emblem support part, an element forming a brand emblem, and at least one luminous element for illuminating the emblem arrangement. The element forming the brand emblem is a layered structure having at least two layers, which layered structure has, when viewed in a plan view of the emblem arrangement, translucent and non-translucent regions. The translucent regions are able to depict the shape of the brand emblem in its entirety or wherein the translucent regions are able to depict merely the contour of the brand emblem.

First claim

The invention claimed is:

1. An emblem arrangement for a motor vehicle, the emblem arrangement comprising:
an emblem support part;
at least one luminous element for illuminating the emblem arrangement; and
an element forming a brand emblem, said element being a layer structure with at least two layers which, as seen in a plan view of the emblem arrangement, is formed with translucent regions and nontranslucent regions, wherein the translucent regions are formed to depict a shape of the brand emblem surface-wide or wherein the translucent regions depict the brand emblem only in a contour thereof;
wherein:
said layer structure includes a first layer being a transparent support sheet and a second layer forming the translucent regions and the nontranslucent regions, said second layer having at least two partial layers lying on one another and including a first partial layer, defining the translucent regions and the nontranslucent regions, and a second partial layer being translucent and having the same color as the translucent regions of said first partial layer;
or:
said layer structure includes a first nontranslucent layer and at least one second nontranslucent layer;
at least one circuit board in an edge region of the emblem arrangement carrying a plurality of luminous means configured to generate light to be coupled in the edge region of the emblem arrangement into a flat light guide; and
said flat light guide, on a side facing away from said layer structure, having a light output structure which is superimposed, in a plan view of an outline of the emblem arrangement, with regions in which said layer structure is entirely removed and which form the translucent regions; and
further comprising an annular light attenuation element arranged between said light guide and a cover glass covering said layer structure.

2. An emblem arrangement for a motor vehicle, the emblem arrangement comprising:
an emblem support part;
at least one luminous element for illuminating the emblem arrangement; and
an element forming a brand emblem, said element being a layer structure with at least two layers which, as seen in a plan view of the emblem arrangement, is formed with translucent regions and nontranslucent regions, wherein the translucent regions are formed to depict a shape of the brand emblem surface-wide or wherein the translucent regions depict the brand emblem only in a contour thereof;
wherein:
said layer structure includes a first layer being a transparent support sheet and a second layer forming the translucent regions and the nontranslucent regions, said second layer having at least two partial layers lying on one another and including a first partial layer, defining the translucent regions and the nontranslucent regions, and a second partial layer being translucent and having the same color as the translucent regions of said first partial layer;
or:
said layer structure includes a first nontranslucent layer and at least one second nontranslucent layer;
at least one circuit board in an edge region of the emblem arrangement carrying a plurality of luminous means configured to generate light to be coupled in the edge region of the emblem arrangement into a flat light guide; and
said flat light guide, on a side facing away from said layer structure, having a light output structure which is superimposed, in a plan view of an outline of the emblem arrangement, with regions in which said layer structure is entirely removed and which form the translucent regions; and
further comprising spacers disposed to produce defined air gaps between said emblem support part and said light guide, between said light guide and said element forming the brand emblem, and/or between said element forming the brand emblem and a cover glass.

3. An emblem arrangement for a motor vehicle, the emblem arrangement comprising:
an emblem support part;
at least one luminous element for illuminating the emblem arrangement; and
an element forming a brand emblem, said element being a layer structure with at least two layers which, as seen in a plan view of the emblem arrangement, is formed with translucent regions and nontranslucent regions, wherein the translucent regions are formed to depict a shape of the brand emblem surface-wide or wherein the translucent regions depict the brand emblem only in a contour thereof;
wherein:
said layer structure includes a first nontranslucent layer and at least one second nontranslucent layer;
at least one circuit board in an edge region of the emblem arrangement carrying a plurality of luminous means configured to generate light to be coupled in the edge region of the emblem arrangement into a flat light guide; and
said flat light guide, on a side facing away from said layer structure, having a light output structure which is superimposed, in a plan view of an outline of the emblem arrangement, with regions in which said layer structure is entirely removed and which form the translucent regions; and
wherein said at least one circuit board has a ring shape.

4. The emblem arrangement according to claim 3 , further comprising a cover glass abutting said layer structure, said cover glass comprising a peripheral circumferential wall on which there is a peripheral layer structure that is different from a remainder of said layer structure and comprises at least three partial layers lying on one another, and wherein color of a partial layer closest to said peripheral wall has a highest brightness and a color of a partial layer farthest away from said peripheral wall has a lowest brightness.

5. The emblem arrangement according to claim 4 , wherein the color of the partial layer farthest away from said peripheral wall is black and the color of the partial layer closest to said peripheral wall has the same color as the translucent regions of said partial layer forming the translucent and nontranslucent regions.

6. The emblem arrangement according to claim 5 , wherein the color of said partial layer closest to said peripheral wall is white.

7. An emblem arrangement for a motor vehicle, the emblem arrangement comprising:
an emblem support part;
at least one luminous element for illuminating the emblem arrangement; and
an element forming a brand emblem, said element being a layer structure with at least two layers which, as seen in a plan view of the emblem arrangement, is formed with translucent regions and nontranslucent regions, wherein the translucent regions are formed to depict a shape of the brand emblem surface-wide or wherein the translucent regions depict the brand emblem only in a contour thereof;
wherein:
said layer structure includes a first layer being a transparent support sheet and a second layer forming the translucent regions and the nontranslucent regions, said second layer having at least two partial layers lying on one another and including a first partial layer, defining the translucent regions and the nontranslucent regions, and a second partial layer being translucent and having the same color as the translucent regions of said first partial layer;
or:
said layer structure includes a first nontranslucent layer and at least one second nontranslucent layer;
at least one circuit board in an edge region of the emblem arrangement carrying a plurality of luminous means configured to generate light to be coupled in the edge region of the emblem arrangement into a flat light guide; and
said flat light guide, on a side facing away from said layer structure, having a light output structure which is superimposed, in a plan view of an outline of the emblem arrangement, with regions in which said layer structure is entirely removed and which form the translucent regions; and
further comprising a cover glass abutting said layer structure, said cover
