摘要

A rear window for an automotive vehicle has imbedded at an upper portion thereof resistance-heating wires for the electrical heating of the window. A window wiper is provided to sweep the window which has a lower portion free from the heating conductors. In its rest (inoperative) position the wiper lies against a portion of the window provided with additional heating elements for rapidly heating the rest position of the wiper to free the wiper, if frozen to the window, to enable the wiper to be brought into play without delay.
