Abstract

A transparency, e.g. a laminated heatable windshield has a pair of spaced bus bars on an electric conductive member e.g. a sputtered electric conductive coating. The perimeter of the coating is spaced from the peripheral edge of the sheet to provide a non-conductive strip. Electric conductive leads connected to the bus bars provide external electric access to the bus bars. End portions of each of the bus bar extend beyond the perimeter of the coating into the non-conductive strip to minimize, if not eliminate, hot spots at the end portions of the bus bars. Additional features to reduce hot spots includes the pair of bus bars having different lengths with one of the bus bar extending along the top side of the coating and one of the bus bars extending along the bottom side of the coating. The portions of the coating between the bus bars do not extend beyond the ends of the longer bus bar. In still a further feature of the invention, the windshield has a vision area having a top edge and a bottom edge, and the coating has a top edge adjacent the top edge of the vision area and a bottom edge adjacent the bottom edge of the vision area. The top bus bars is adjacent the top edge of the coating and the bottom bus bar is adjacent the bottom edge of the coating with both bus bars outside of the vision area. The bottom edge of the coating is spaced a greater distance from the bottom edge of the vision area than the bottom bus bar and the top edge of the coating is spaced a greater distance from the top edge of the vision area than the top.
