Laminated glazing for a motor vehicle, particularly a side glazing
A laminated glazing for a motor vehicle, particularly a side glazing intended to be slidably mounted in a door of the vehicle, includes at least one outer glass sheet and one inner glass sheet assembled by an interlayer which includes at least one sheet of polymer material, the glazing including at least one part for attaching the glazing provided with at least one attachment hole which has an axis and passes at least through the outer glass sheet, the attachment hole being intended to receive a system for attaching the glazing with a drive device, wherein the glazing includes at least one insert which, including a hole, is housed in a complementary cut-out provided in the interlayer, at the attachment part.
1. A laminated glazing for a motor vehicle, comprising:
an outer glass sheet and an inner glass sheet assembled by an interlayer which comprises at least one sheet of polymer material,
at least one attachment part for attaching the laminated glazing and provided with at least one attachment hole which has an axis and passes through at least the outer glass sheet, said attachment hole being intended to receive an attachment system to attach said laminated glazing with a drive device, and
at least one insert which, comprising a hole, is housed in a complementary cut-out provided in the interlayer, at the attachment part such that at least portion of the at least one insert is sandwiched between the outer glass sheet and the inner glass sheet.
2. The laminated glazing according to claim 1 , wherein the insert comprises an outer face which is in direct contact with an inner face of the outer glass sheet and an inner face of which all or at least one part is in direct contact with an outer face of the inner glass sheet.
3. The laminated glazing according to claim 1 , wherein the insert is made of a material having a hardness greater than that of the interlayer comprising at least said sheet of polymer material.
4. The laminated glazing according to claim 1 , wherein said insert is made of a plastic material, or a metal material.
5. The laminated glazing according to claim 1 , wherein the hole is formed in the insert after assembly of said outer and inner glass sheets of the laminated glazing.
6. The laminated glazing according to claim 1 , wherein the hole of the insert has a diameter between 10 mm and 30 mm.
7. The laminated glazing according to claim 1 , wherein the insert comprises a bushing which, extending along the axis O, is configured to pass through at least one part of the outer glass sheet provided with a hole and/or of the inner glass sheet provided with a hole.
8. The laminated glazing according to claim 7 , wherein the insert comprises a core projecting with respect to one and/or the other of an outer and an inner faces of the insert, said core being intended to be bored so as to form the bushing which said hole passes through, preferentially bored after assembly of said outer and inner glass sheets of the laminated glazing.
9. The laminated glazing according to claim 1 , wherein the insert has a thickness that is equal to a thickness of the interlayer+/−10%.
10. The laminated glazing according to claim 1 , wherein the insert is configured to form a spacer between the outer glass sheet and the inner glass sheet so as to limit creep of the polymer material of said at least one sheet of the interlayer.
11. The laminated glazing according to claim 1 wherein the inner glass sheet comprises at least one cut-out provided in the attachment part for attaching the laminated glazing so that the attachment system engages with the insert without contact with said inner glass sheet.
12. The laminated glazing according to claim 11 , wherein the cut-out of the inner glass sheet has dimensions smaller than those of the insert so that the insert engages around said cut-out with a part of an outer face of the inner glass sheet.
13. The laminated glazing according to claim 1 , wherein the insert comprises at least one part configured to form a holding surface capable of retaining the insert vertically in position.
14. The laminated glazing according to claim 1 , wherein the laminated glazing is symmetric, said at least one attachment part for attaching the glazing comprising the outer glass sheet, the insert and the inner glass sheet.
15. The laminated glazing according to claim 1 , wherein the insert comprises de-airing means configured to allow a discharge of the air contained in the interlayer during assembly of the laminated glazing.
16. The laminated glazing according to claim 1 , wherein the laminated glazing is a side glazing that is slidably mounted in a door of the motor vehicle.
17. The laminated glazing according to claim 3 , wherein the sheet of polymer is a sheet of polyvinyl butyral (PVB).
18. The laminated glazing according to claim 3 , wherein the material of the insert has a Shore D hardness between 70 and 90.
19. The laminated glazing according to claim 4 , wherein said plastic material is polyamide (PA), polyoxymethylene (POM), polybutylene terephthalate (PBT), or polyethylene terephthalate (PET) and said metal material is steel.
20. The laminated glazing according to claim 6 , wherein the hole of the insert has a diameter between 15 mm and 25 mm.
