Abstract

A glazing includes a laminated glazed element including an exterior glass sheet, an interior glass sheet, and at least one plastic interlayer sheet situated between the glass sheets, and, along at least part of at least one edge, a profile section including a functional part provided with a groove and a fixing part for fixing it to the glazed element. The fixing part includes an interlayer flange which, viewed in cross section, is situated between the interlayer face of the exterior glass sheet and the interlayer face of the interior glass sheet; of the interior face and the exterior face of the interlayer flange at least one face being in contact with the plastic interlayer sheet.

First claim

The invention claimed is:

1. A glazing, comprising a laminated glazed element comprising an exterior glass sheet, an interior glass sheet, and at least one plastic interlayer sheet situated between said exterior and interior glass sheets,
said exterior glass sheet having an exterior face, an edge face and an interlayer face which faces toward said plastic interlayer sheet,
said interior glass sheet having an interlayer face which faces toward said plastic interlayer sheet, an edge face and an interior face,
said glazing comprising, along at least part of at least one edge, a profile section comprising a functional part provided with a groove and a fixing part for fixing the profile section to the glazed element,
wherein the fixing part comprises an interlayer flange which, viewed in cross section, is situated between the interlayer face of said exterior glass sheet and the interlayer face of said interior glass sheet, said interlayer flange comprising an exterior face facing toward the exterior glass sheet, an interior face facing toward the interior glass sheet and an edge face, and
wherein the interior face or the exterior face of the interlayer flange is, or both the interior face and the exterior face of the interlayer flange are, in contact with said at least one plastic interlayer sheet.

2. The glazing as claimed in claim 1 , wherein the exterior face and the edge face of the interlayer flange are in contact with said at least one plastic interlayer sheet and the interior face of the interlayer flange is connected, by contact or via the interposition of a layer of adhesive material, with the interlayer face of the interior glass sheet.

3. The glazing as claimed in claim 1 , wherein the glazed element comprises at least one exterior interlayer sheet and one interior interlayer sheet made of plastic between the exterior glass sheet and the interior glass sheet, the exterior face of the interlayer flange being in contact with the exterior interlayer sheet and the interior face of the interlayer flange being in contact with the interior interlayer sheet.

4. The glazing as claimed in claim 3 , wherein the glazed element further comprises a third plastic interlayer sheet between the exterior interlayer sheet and the inferior interlayer sheet, the edge face of the interlayer flange being in contact with an edge face of said third interlayer sheet.

5. The glazing as claimed in claim 1 , wherein the groove is open toward the exterior.

6. The glazing as claimed in claim 1 , wherein the profile section has, in cross section, two recesses that are open in the same direction or in opposite directions, a first recess forming the groove and a second recess fitting over the exterior glass sheet.

7. The glazing as claimed in claim 1 , wherein the interlayer flange has a width comprised between 5 and 40 mm.

8. The glazing as claimed in claim 1 , wherein the interlayer flange is corrugated.

9. The glazing as claimed in claim 1 , wherein the profile section comprises at least one body part made of a thermoplastic material delimiting the groove, and at least one fixing insert provided with a distal part inserted into said body part and with a proximal part that projects out of said body part.

10. The glazing as claimed in claim 9 , wherein the interlayer flange is made up at least in part of said proximal part of the fixing insert.

11. The glazing as claimed in claim 1 , wherein the interlayer flange has at least one cavity.

12. The glazing as claimed in claim 1 , wherein the profile section is provided with a sealing lip between the groove and the interlayer flange.

13. The glazing as claimed in claim 1 , wherein the groove is configured for clip-fastening a cover piece onto said profile section.

14. An assembly, comprising
a glazing as claimed in claim 1 , wherein the groove is configured for the clip-fastening of a cover piece onto said profile section, and
a cover piece comprising, viewed in cross section, a barbed hook that enters said groove during clip-fastening.

15. The assembly as claimed in claim 14 , wherein the cover piece is a scuttle panel or a trim element.

16. An assembly comprising
a glazing as claimed in claim 1 , and
a bodywork component,
the profile section bearing against said bodywork component.

17. The assembly as claimed in claim 16 , wherein the bodywork component has a main portion and an end portion that is set back toward the interior with respect to said main portion and connected thereto by a shoulder, and the functional part of the profile section bears against the shoulder, and the glazed element is fixed by bonding to said end portion.

18. A profile section for a glazing as claimed in claim 1 , comprising at least one body part made of a thermoplastic material delimiting a groove, and at least one fixing insert provided with a distal part inserted into said body part and with a proximal part that projects out of said body part.

19. The profile section as claimed in claim 18 , wherein the proximal part of the fixing insert has a plurality of through-openings.

20. A method for producing a glazing as claimed in claim 1 , comprising a step of laminating the exterior glass sheet and the interior glass sheet of the glazed element using at least one plastic interlayer sheet, the lamination step involving placing the interlayer flange of the profile section between the exterior glass sheet and the interior glass sheet in contact with said at least one interlayer sheet.
