  • Patent number: 8151470
    Abstract: To alleviate ice freeze-up of vehicle windows which incorporate spaced upper and lower seals which engage an outside surface of the vehicle window, a tool is provided with a handle and a blade extending from the handle and the blade has a bend and a distal end which is curved outwardly in the plane of the blade. The length of the blade segment between the bend and its distal end is selected to be slightly longer than the distance between the upper and lower seals whereby this blade segment may be inserted between the window outside surface and the upper and lower seals and then slid along the window to sever any ice seal existing between the outside window surface and the upper and lower seals to free up the frozen vehicle window for normal operation.
