Abstract
An electrically heated vision unit, such as a windshield, has bus bars extending substantially parallel to, and spaced from, each other in contact with an electrically conductive film provided on a surface of a transparent substrate. One bus bar extends laterally beyond the corresponding end of the opposite bus bar, an end portion at such corresponding end of the opposite bus bar being recessed away to avoid excessive current density at such recessed end portion.
