It is thus possible to melt dew adhering to the inside of the windshield glass 7 and frost adhering to the outside to ensure visibility.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heater-equipped light shielding body for a vehicle, which is equipped with a heater effective for defrosting the windshield of a vehicle or the like.

Conventional technology When it comes to defrosting the windshields of vehicles, etc., it is a big safety issue that the driver's view must not be obstructed, so a heater is installed on the rear windshield.
Most other windshields are defrosted using warm air using the heat from the engine's cooling water.

FIG. 12 shows an example of defrosting the windshield glass 7 of vehicle i using warm air 31. Warm air 31 is blown from the defroster nozzle 30 to melt dew adhering to the inner surface of the windshield glass 7 and frost adhering to the outer surface. This is to ensure visibility.

In the 13th episode, warm air 3 from the defroster nozzle 30 described above
A conventional method other than the method of blowing out water 1, in which thin film heaters 33a and 33b are arranged on the windshield glass 7 to melt dew adhering to the inner surface of the windshield glass 7 and frost adhering to the outer surface to ensure visibility. (Jitsukai 62-122
