IN THE C A N A D I A N PATENT & TRADEMARK OFFICE PATENT APPLICATION entitled: Heating device for hydrometric sensor for automatically controlling vehicle equipment, particularly windscreen wipers in the name of: Bernard MANZONI assigned to: MANZONI-BOUCHOT ABSTRACT OF THE DISCLOSURE This invention relates to a heating device for hygrometric sensor inserted in a circuit for automatically controlling vehicle equipment, compri- sing at least one electrical heating resistor located in the support of the sensor and in the vicinity thereof, this resistor being connected to the termi- nals of a constant voltage source when the engine of the vehicle is switched on. Between one of the terminals of the source of voltage and the correspon- ding terminal of the heating resistor, there is connected a threshold temperature detector, for example of the bimetal type or the like, disposed in the support of the sensor and in the vicinity of its humidity detector resistor, said detector ensuring cut-off of the supply circuit of the heating resistor when the temperature of the sensor attains a predetermined value.
