Abstract

A glazing, and in particular an automotive glazing, includes a laminated glazed element including an exterior glass sheet, an interior glass sheet and a plastic interlayer sheet that is located between the two glass sheets and including at least one light-emitting diode that is located under a peripheral edge of the interlayer face of the exterior glass sheet, wherein the emitting face of the light-emitting diode is located facing at least a part of the edge face of the interior glass sheet and wherein the glazing includes a profiled bead including an exterior lip an interior lip and a body, with the body being located a distance away from, and not in contact with, the emitting face of the light-emitting diode.

First claim

The invention claimed is:

1. A glazing, comprising a laminated glazed element comprising an exterior glass sheet, an interior glass sheet and a plastic interlayer sheet that is located between said exterior and interior glass sheets,
said exterior glass sheet having an exterior face, an edge face and an interlayer face that is oriented toward said plastic interlayer sheet,
said interior glass sheet having an interlayer face that is oriented toward said plastic interlayer sheet, an edge face and an interior face,
said glazing including at least one light-emitting diode located under a peripheral edge of said interlayer face of said exterior glass sheet and having an emitting face,
wherein said emitting face is located facing at least a part of said edge face of said interior glass sheet and wherein the glazing includes a profiled bead including
an exterior lip in contact with said peripheral edge of said interlayer face of said exterior glass sheet and/or said edge face of said exterior glass sheet,
an interior lip in contact with a peripheral edge of said interior face of said interior glass sheet, and
a body located between, and connecting, said exterior lip and said interior lip,

with said body being located a distance away from the entirety of the light-emitting diode and not in contact with said light-emitting diode; wherein said light-emitting diode is attached to said peripheral edge of said interlayer face of said exterior glass sheet with an adhesive layer, said body being located a distance away from, and not in contact with said adhesive layer.

2. The glazing as claimed in claim 1 , wherein said interior lip does not lie against said edge face of said interior glass sheet.

3. The glazing as claimed in claim 1 , wherein said interior lip is in contact with said peripheral edge of said interior face of said interior glass sheet over only a part of its length.

4. The glazing as claimed in claim 1 , wherein said exterior lip has a width comprised between 1.0 and 3.0 mm and a height comprised between 1.0 and 5.0 mm.

5. The glazing as claimed in claim 1 , wherein said interior lip has a width comprised between 1.0 and 10.0 mm and a height comprised between 1.0 and 3.0 mm.

6. The glazing as claimed in claim 1 , further comprising an additional protective profile that at least partially covers an interior face of said profiled bead, the interior face of said profiled bead being the face furthest away from said light-emitting diode.

7. A process for manufacturing a glazing as claimed in claim 1 , comprising positioning said profiled bead, by extruding a constituent material of said profiled bead, with said body located a distance away from said emitting face of the light-emitting diode and not in contact with said emitting face.

8. The process as claimed in claim 7 , further comprising manufacturing an additional protective profile by encapsulating said profiled bead.

9. The glazing as claimed in claim 1 , wherein the glazing is an automotive glazing.

10. The glazing as claimed in claim 1 , wherein said body is located a distance away from, and not in contact with, said edge face of said interior glass sheet.

11. The glazing as claimed in claim 1 , wherein and said exterior lip is located a distance away from, and not in contact with, said adhesive layer.

12. The glazing as claimed in claim 6 , wherein the additional protective profile completely covers the interior face of said profiled bead.

13. The process as claimed in claim 7 , wherein the body is located a distance away from, and not in contact with, said edge face of said interior glass sheet.

14. The glazing as claimed in claim 1 , wherein said profiled bead is a one-piece element.

15. The glazing as claimed in claim 1 , wherein said body includes a first interior face that is oriented so as to face the interlayer face of the exterior glass sheet and to face the interior face of the interior glass sheet, and a first exterior face, said first exterior face being opposite the first interior face, and wherein the first interior face is out of contact with the interlayer face of the exterior glass sheet and with the interior face of the interior glass sheet.
