AUTOMOTIVE GLAZING AND METHOD OF MANUFACTURING SAME
First Claim
1. An automotive glazing, comprising a laminated glazing sheet including a first glazing sheet and a second glazing sheet laminated to an outboard side of the first glazing sheet, and a seal member attached to a peripheral part of the laminated glazing sheet, the automotive glazing further comprising:
- a cutout formed in a peripheral part of the first glazing sheet;
an electro-conductive pattern formed on an inboard side of the second glazing sheet;
electrode pieces connected to parts of the electro-conductive pattern and placed on the inboard side of the second glazing sheet within the cutout of the first glazing sheet;
flexible terminal pieces bonded to the corresponding electrode pieces; and
a cover member placed in the cutout so as to at least partly cover the electrode pieces and associated parts of the terminal pieces and defining an inboard surface substantially flush with an inboard side of the first glazing sheet;
wherein the seal member is bonded to a peripheral part of the inboard side of the first glazing sheet and the inboard surface of the cover member, and the terminal pieces are drawn from the electrode pieces out of the cutout via the cover member.

Abstract
In an automotive glazing comprising a laminated glazing sheet (2) including a first glazing sheet (6), a second glazing sheet (8) laminated to an outboard side of the first glazing sheet and an electric device (13) placed between the first and second glazing sheets, and a seal member (4) attached to a peripheral part of the laminated glazing sheet, a cutout (11) is formed in a peripheral part of the first glazing sheet, and a support member (24) defining an inboard surface (26) flush with an inboard side of the first glazing sheet is placed in the cutout. Terminal pieces (17) are drawn from electrode pieces (12) of the electric device out of the cutout via a gap defined between an edge of the first glazing sheet defining the cutout and an opposing edge of the support member. The terminal pieces include free end parts bonded to the corresponding electrode pieces and drawn away from an adjoining peripheral part of the second glazing sheet, and base end parts bent back toward the peripheral part of the second glazing sheet and extending along an inboard side of the seal member.

12. A method of manufacturing an automotive glazing, comprising the steps of:
-
preparing a laminated glazing sheet including a first glazing sheet having a cutout formed in a peripheral part thereof, a second glazing sheet laminated to an outboard side of the first glazing sheet, an electro-conductive pattern formed on an inboard side of the second glazing sheet, electrode pieces connected to parts of the electro-conductive pattern and placed on the inboard side of the second glazing sheet within the cutout of the first glazing sheet; bonding an end of a flexible terminal piece to each of the electrode pieces, and drawing another end of the terminal piece out of the cutout; depositing a sealant in the cutout so as to at least partly cover the electrode pieces and corresponding parts of the terminal pieces; placing a support member in the cutout before the sealant has cured such that the support member defines a support surface substantially flush with the inboard side of the first glazing sheet; and attaching a seal member to an inboard side of a peripheral part of the first glazing sheet and the support surface of the support member.
