Abstract
This specification is directed to a process for making part of an electrically heated windshield assembly. The process includes the steps of selecting a glass sheet 10. The glass sheet is formed into a windshield configuration. At least a pair of electrically conductive bus bars (14, 16) are formed on the glass sheet. One bus bar (14) extends along a lower edge of the glass sheet. A second of the bus bars (16) extends along at least a short portion (20) of the lower edge of the glass sheet in a location spaced away from the bus bar (14) and near the lower edge of the glass sheet, up a side edge of the lower edge of the glass sheet as an edge portion (22), and along an upper edge of the glass sheet as an upper portion (24). A snap-on protective member (30) is placed on the glass sheet which engages both front and back surfaces of that glass sheet. The snap-on protective member covers over lower portions and side edge portions of the second bus bar (16). The surface of the glass sheet having the bus bars thereon is subjected to a vacuum metal deposition process to form an electrically conductive coating (32) between the bus bars uncovered by the snap-on protective member. Thereafter,…
