The car seat heating switch icon is a seat sign with three arrows pointing upward from the bottom of the seat. There is a row of buttons above the air conditioning control keys at the lower part of the center console. The button in the red box on the left is the driver's seat heating switch, and the button on the right is the passenger seat heating switch. Seat heating is to use the electric heating wire in the seat to heat the interior of the seat, and transfer the heat to the occupant through heat transfer, so as to improve the uncomfortable feeling caused by the seat being too cold after long-term parking in winter.

Heating principle of automobile seat

Below the seat cushion is a non-woven fabric with electric heating wires. After the heating switch of the seat in the car is turned on, the heating wire is energized, and the seat will generate temperature, so that the seat will gradually heat up in a short time. It is similar to the principle of electric blanket. Generally, there is a temperature sensor in the electric heating pad, which can monitor the change of the seat temperature, so as to control the power-on and power-off of the electric heating wire and keep the heating temperature of the seat within a suitable range.
