Abstract

A glazing includes a laminated glazed element. The glazing includes a profiled strip including a groove for the clip fastening of a cover piece. The glazing further includes a polymer tape situated between the groove and an edge face of an interior substrate, or even also between a peripheral edge of an interior face and an interior flange.

First claim

The invention claimed is:

1. A glazing, comprising:
a laminated glazed element comprising
an exterior substrate having an exterior face which faces an exterior space, an intermediate face opposite the exterior face, and a peripheral edge face,
an interior substrate having an interior face which faces an interior space, an intermediate face opposite the interior face, and a peripheral edge face,
a plastic interlayer situated between and in contact with the intermediate face of said exterior substrate and the intermediate face of said interior substrate, and

a profiled strip arranged along at least part of at least one edge of said laminated glazed element, the profiled strip comprising a groove for a clip-fastening of a cover piece to said profiled strip, said cover piece comprising, viewed in cross section, a barbed hook that enters said groove during clip-fastening,
said profiled strip comprising a lip situated against said peripheral edge face of said exterior substrate,
said profiled strip comprising, viewed in cross section, an interior flange situated underneath a peripheral edge of said interior face of said interior substrate, and
a polymer tape situated between said groove and said peripheral edge face of said interior substrate so as to fill a space extending from said profiled strip to said peripheral edge face of said interior substrate.

2. The glazing as claimed in claim 1 , wherein said tape has a width between said groove and said peripheral edge face which is comprised between 0.2 and 5.0 mm.

3. The glazing as claimed in claim 1 , wherein said tape is situated underneath and in contact with said lip.

4. The glazing as claimed in claim 1 , wherein said tape is in contact with said peripheral edge face of said exterior substrate.

5. The glazing as claimed in claim 1 , wherein said tape has, in cross section, the shape of a square, a rectangle or an L.

6. The glazing as claimed in claim 1 , wherein said glazing forms a vehicle windshield and said tape is situated along a lower edge of the vehicle windshield.

7. The glazing as claimed in claim 1 , wherein said tape, viewed in cross section, is situated between said groove and an adhesive band which is situated on said interior flange.

8. The glazing as claimed in claim 1 , wherein said interior flange of said profiled strip comprises at least one hole passing through said interior flange.

9. The glazing as claimed in claim 1 , wherein, viewed in cross section, said exterior face of said exterior substrate is free with respect to said groove.

10. A profiled strip for a glazing as claimed in claim 1 , comprising a polymer tape which extends longitudinally in a corner between said groove and said interior flange.

11. The glazing as claimed in claim 1 , wherein the glazing is a vehicle glazing.

12. The glazing as claimed in claim 1 , wherein the polymer tape is also situated between said peripheral edge of said interior face and said interior flange.

13. The glazing as claimed in claim 2 , wherein the width is between 0.5 and 3.0 mm.

14. The glazing as claimed in claim 8 , wherein said hole has a length comprised between 2.0 and 50.0 mm and a width comprised between 2.0 and 10.0 mm.

15. The glazing as claimed in claim 9 , wherein said groove is flush with said exterior face.

16. The glazing as claimed in claim 1 , wherein the polymer tape is in contact with both the profiled strip and said peripheral edge face of said interior substrate.

17. The glazing as claimed in claim 1 , wherein the lip of the profiled strip is in contact with said peripheral edge face of said exterior substrate.

18. A glazing, comprising:
a laminated glazed element comprising
an exterior substrate having an exterior face which faces an exterior space, an intermediate face opposite the exterior face, and a peripheral edge face,
an interior substrate having an interior face which faces an interior space, an intermediate face opposite the interior face, and a peripheral edge face,
a plastic interlayer situated between and in contact with the intermediate face of said exterior substrate and the intermediate face of said interior substrate, and

a profiled strip arranged along at least part of at least one edge of said laminated glazed element, the profiled strip comprising a groove for a clip-fastening of a cover piece to said profiled strip, said cover piece comprising, viewed in cross section, a barbed hook that enters said groove during clip-fastening,
said profiled strip comprising a lip situated against said peripheral edge face of said exterior substrate,
said profiled strip comprising, viewed in cross section, an interior flange situated underneath a peripheral edge of said interior face of said interior substrate, and
a polymer tape situated between said groove and said peripheral edge face of said interior substrate and arranged in contact with said profiled strip and said peripheral edge face of said interior substrate.

19. The glazing as claimed in claim 18 , wherein said tape is situated underneath and in contact with said lip.

20. The glazing as claimed in claim 18 , wherein said tape is in contact with said peripheral edge face of said exterior substrate.
