Document Type and Number:
WIPO Patent Application WO/2018/205897
Kind Code:
A1
Abstract:
Disclosed is a heating device (300), in particular, a heating device (300) for a car seat. The device comprises: a carrier (301); positive and negative electrodes (302, 303) fixed on the carrier (301) and used for connection to a power supply; and a plurality of electric heating wires (304) fixed on the carrier (301) and conductively connected to the positive and negative electrodes (302, 303). According to the present invention, a heating area is defined between the positive and negative electrodes (302, 303) by means of the plurality of electric heating wires (304), and at least one electric heating wire (304) of the plurality of electric heating wires (304) is tortuously arranged in a different shape to other electric heating wires (304), such that an absolute value of a heat power density difference between any two measured parts within the heating area is less than a specified value for the same, thereby allowing the whole heating area to evenly heat up when a heating pad is energized.
