Abstract

A vehicle glazing includes a glazed element, at least one portion of extruded seal, at least one trim having an outer face and an inner face, and a core, having an elongate form and having, in cross section, a head and a foot, wherein the portion of extruded seal is manufactured by molding a plastic material on the glazed element.

First claim

The invention claimed is:

1. A vehicle glazing, comprising a glazed element, at least one portion of extruded seal, at least one trim having an elongate form which extends along an edge of said glazed element and having an outer face visible from an outside of a vehicle on which the vehicle glazing is to be mounted and an inner face situated opposite said outer face, and a core, having an elongate form and having, in cross section, a head and a foot, said core being situated under said trim with at least a part of said head in contact with said inner face of the trim and said foot which protrudes under said trim with at least a part of said foot which is not in contact with said inner face of the trim, said portion of extruded seal, seen in cross section, being in contact with said glazed element, said foot and a part of said outer face of the trim, wherein said portion of extruded seal is manufactured by molding a plastic material on said glazed element, on said foot and on the part of said outer face of the trim.

2. The glazing as claimed in claim 1 , wherein said core adheres either directly, or via a glue, with said portion of extruded seal and/or said foot has, on at least a part of a contour, at least one longitudinal groove.

3. The glazing as claimed in claim 1 , wherein said portion of extruded seal has, on the outer face, a hollow of a form complementing a perimeter of said foot.

4. The glazing as claimed in claim 1 , wherein said foot has, seen in cross section, a section which is wider in proximity to the head and which is narrower away from the head.

5. The glazing as claimed in claim 1 , wherein said trim comprises at least one tab which is situated on a longitudinal edge of said trim and which is folded back into contact with said foot.

6. The glazing as claimed in claim 5 , wherein said trim further comprises at least one opposite tab which is situated on an opposite longitudinal edge of said trim and which is folded back into contact with said foot.

7. The glazing as claimed in claim 1 , wherein said core has a length equal to a length of said trim.

8. The glazing as claimed in claim 1 , wherein said portion of extruded seal, seen in cross section, is in contact with an outer face, an inner face and an edge face of said glazed element and wherein said trim is situated at least partly above said outer face of said glazed element.

9. The glazing as claimed in claim 1 , wherein said foot comprises at least one transverse hole for a passage of the material of said portion of extruded seal.

10. A method for manufacturing a vehicle glazing, said vehicle glazing comprising a glazed element, at least one portion of extruded seal, at least one trim having an elongate form which extends along an edge of said glazed element and having an outer face visible from an outside of a vehicle on which the vehicle glazing is to be mounted and an inner face situated opposite said outer face, and a core, having an elongate form and having, in cross section, a head and a foot, said core being positioned under said trim with at least a part of said head in contact with said inner face of the trim and said foot which protrudes under said trim with at least a part of said foot which is not in contact with said inner face of the trim, the method comprising manufacturing said portion of extruded seal by molding a plastic material on said glazed element, on said foot and on a part of said outer face of the trim with said portion of extruded seal, seen in cross section, which is in contact with said glazed element, said foot and a part of said outer face of the trim.

11. The method as claimed in claim 10 , wherein said core adheres either directly, or via a glue, with said plastic material of said portion of extruded seal and/or said foot has, over at least a part of a contour, at least one longitudinal groove.

12. The method as claimed in claim 10 , wherein said trim comprises at least one tab which is situated on a longitudinal edge of said trim and which is folded back into contact with said foot before the molding of said portion of extruded seal.

13. The method as claimed in claim 12 , wherein said trim further comprises at least one opposite tab which is situated on an opposite longitudinal edge of said trim and which is folded back into contact with said foot before the molding of said portion of extruded seal.

14. The glazing as claimed in claim 1 , wherein the trim has, in cross section, a central base and two opposite wings which extend from two opposite edges of said base and wherein said portion of extruded seal, seen in cross section, is in contact with said two opposite wings.
