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.
