阅读说明：本技术 侧窗层压汽车玻璃 (Laminated automotive glass for side window ) 是由 R·洛索特 S·卓格曼 于 2018-05-08 设计创作，主要内容包括：本发明涉及一种可电加热的层压汽车玻璃件,包括弯曲的并且钢化的外玻璃片材和也钢化的薄玻璃内部片材,这些片材通过热塑性间层片材接合,所述玻璃件被配置为接收机械移动和/或紧固装置,并且外部片材的一部分没有被薄内部片材覆盖,并且所述玻璃件被紧固在没有被薄片材覆盖的区中,所述玻璃件包括至少一个可电加热区,所述至少一个可电加热区包括：(i)基本上透明的导电涂层以及(ii)隔开的母线,所述母线适于在所述基本上透明的导电涂层上供应电压。根据本发明,所述隔开的母线被放置在所述外部片材的未被所述薄内部片材覆盖的部分中。(The present invention relates to an electrically heatable laminated automotive glazing comprising a curved and toughened outer glass sheet and a thin also toughened glass inner sheet joined by a thermoplastic interlayer sheet, the glazing being configured to receive mechanical movement and/or fastening means and a portion of the outer sheet being uncovered by the thin inner sheet and the glazing being fastened in a region not covered by the thin sheet, the glazing comprising at least one electrically heatable region comprising: (i) a substantially transparent conductive coating and (ii) spaced bus bars adapted to supply a voltage across the substantially transparent conductive coating. According to the invention, the spaced bus bars are placed in the portion of the outer sheet not covered by the thin inner sheet.)

1. An electrically heatable laminated automotive glazing comprising a curved and toughened outer glass sheet and a also toughened thin glass inner sheet joined by a thermoplastic interlayer sheet, the glazing being configured to receive mechanical movement and/or fastening means and a portion of the outer sheet being uncovered by the thin inner sheet and the glazing being fastened in a region not covered by the thin sheet,

the glass piece includes at least one electrically heatable zone comprising:

iii) a substantially transparent conductive coating,

iv) spaced bus bars adapted to supply a voltage across the substantially transparent conductive coating,

characterised in that the spaced busbars are placed in the portion of the outer sheet not covered by the thin inner sheet.

2. The glass piece of claim 1, wherein the conductive coating has a conductive path defined between the bus bars, wherein at least at one of the electrically heatable zones, the conductive path changes direction within the conductive coating at least once along its length so as to double back on itself.

3. Glazing according to claim 1 or 2, characterized in that the outer sheet has a thickness not greater than 5 mm.

4. Glass piece according to any of the preceding claims, characterized in that the thickness of the thin inner sheet is not more than 1 mm.

5. Glass piece according to any of the preceding claims, characterized in that the thickness of the thin glass inner sheet is not less than 0.2 mm.

6. A glazing as claimed in any preceding claim, wherein the thin glass inner sheet has no significant curvature before it is joined to the curved outer glass sheet.

7. A glazing as claimed in any preceding claim, wherein the thin glass inner sheet is chemically toughened.

8. Glass element according to any one of the preceding claims, characterized in that the thin glass inner sheet is coated on its side facing the interlayer sheet with a set of functional layers having non-heat conducting properties.

9. Glass piece according to any one of the preceding claims, characterized in that the non-overlapping portions of the sheets represent not more than 20% of the area of the outer sheet.

10. Glass element as claimed in any one of the preceding claims, characterized in that the non-overlapping parts of the sheets represent at least 0.5% of the area of the outer sheets.

11. Glazing according to any of the preceding claims, characterized in that the outer sheet comprises a hole in the non-laminated portion, the hole being configured to receive means for fastening/moving the glazing.

12. A glazing as claimed in any preceding claim, wherein the glazing forms a movable side window.

13. Glass piece according to any of the preceding claims, characterized in that the glass piece is a carrier for additional elements that require the glass piece to be processed.
