Abstract: A defogging and defrosting rear window pane for motor vehicles has a plurality of spaced heating elements embedded therein. A relatively short metallic collector having a circular segment configuration is provided in each peripheral side of the window pane at opposite margins thereof. The central heating element extends between the collectors in a rectilinear path. Additional heating elements above and below the central element have a rectilinear central portion parallel to the central element and are connected to the collectors by end portions converging on the respective collectors. The respective collectors have an appendix extending outwardly beyond the window weatherstripping to serve as a terminal for connection to a power source.

Abstract: An electric connector for electrically heatable window panes including a tin-plated platelet solderable to a bus conductor having a tongue integral with the platelet bent at an angle with the platelet and adapted to be connected to the feed wire, wherein the area of the soldered joint is extended to both sides of the axis of the bend.
