What is car seat heating?

Seat heating refers to the electric heating device in the seat. It usually appears on vehicles with leather seats. Because the surface material of leather seats is low in winter, it is not a cold leather chair to sit down and wait on you in cold winter after the seats are heated. Most electric heating devices have the function of temperature adjustment.

In winter, many car owners find that the heating in the car starts slowly, and the whole back is chilly when sitting in a leather seat, so that they can't hold the steering wheel. How to heat the car body early before the car heating works normally? During the visit, Bian Xiao learned that most high-end cars on the market have been equipped with seat heating function, which can heat the whole seat surface through the electric heating device in the leather seat, giving the owner a warm and comfortable feeling in the cold winter. And those car owners who don't have heated seats can also install seat devices in auto decoration and beauty markets and auto parts stores. Is this seat device safe? Industry insiders remind that power seats and other configurations cannot be installed by themselves, so be careful when purchasing.

Heating the seat has a good effect, and the principle is the same as that of an electric blanket.

At present, many A-class cars with a price of more than 654.38+0.5 million yuan are equipped with heated seats (such as German Benz, BMW, Audi, Volkswagen, Passat, Bora, etc.). However, for most low-end models, the seat heating function has not been well popularized, so some car owners will realize similar functions by purchasing and installing heated seats themselves. The reporter visited several car decoration and beauty markets in Jinhua, and found that there are two kinds of car heating seats: one is an external seat device, and the heating pad inserted into the car cigarette lighter costs 50~ 100 yuan; Another built-in seat device requires professionals to install and replace wiring in the car, and the price is 200~500 yuan. The heating effect of these heated seats is quite good. When the switch is set to high-grade heating for 5 minutes, the temperature of the whole seat can rise by 15℃, and when it is set to medium-low grade, the temperature can remain constant for a long time. The temperature range of the whole seat is kept at 30~65℃.

When answering Bian Xiao's question about whether it is safe to install a heated seat, the seller of an automobile supplies franchise store in the city said that the heated seat has built-in sensors and protective devices, which can feel pressure and temperature. When the temperature is lower than 5℃, the circuit starts, and when it is higher than 65℃, the power supply is automatically cut off. When the cushion is pressed, it will automatically heat up. After the pressure disappears, the induction stops heating up. In other words, only the owner sits in the heated seat, otherwise the heating will stop. "The principle of heating seats is similar to that of electric blankets. Since the electric blanket has been accepted by everyone, why not heat the seat for the car? " Shopkeepers said that their products are produced in strict accordance with the special requirements of electric blankets, electric pads and other similar flexible heating appliances, and have a safe service life of three years and symbols. As long as the owner strictly follows the requirements, there will be no danger.

Consumers who modify the line have many concerns.

In a decoration shop in the city, Bian Xiao witnessed the whole process of installing the heated seat: first, the staff took off the outer seat cover of the seat, then tore off the adhesive on the back of the carbon fiber heating pad, stuck it on the seat and backrest sponge, connected the control switch and the dial wheel with connectors, then covered the seat cover and inserted the temperature control switch into the hole reserved in the car, so that the plug of the temperature control switch and the interface of the heating pad could be docked. As long as the car power is turned on, the heating pad will start to heat up. It is necessary to connect the main line, grounding line, running light line and ACC control line, and it is generally not recommended for the owner to operate by himself.

Does the customer need to modify the wiring when installing the built-in car heating seat? Bian Xiao learned in the interview that many car owners have concerns about heated cushions, mainly in the following aspects: First, they question the safety of installing heated seats. Some car owners are afraid that the modified circuit will affect the original circuit, resulting in short circuit or spontaneous combustion of the car body. Some car owners have installed heated seats, but they are still worried about heating for a long time, fearing that the seats will age and leak electricity. There is also a concern about the impact of the modified line on the car itself. Mr. Wu, who is onlookers, thinks that the seat modification may affect the effective ejection of the side airbag, causing safety hazards.

Heated seats cannot be installed at will.

At present, there are many brands of heated seats in Jinhua, some of which are poorly packaged and lack of effective data marks, so the quality is difficult to guarantee. Liu, a car decoration department in Jinhua, said that the external heating pad is often directly connected to the cigarette lighter, and it is particularly easy to blow the fuse when heating; However, some built-in car heating pads are not directly connected with cigarette lighters, so the wiring needs to be changed during installation, and the voltage limit of each car is stipulated. Once a new resistor is added, it may cause short circuit of vehicle current and even fire. Therefore, car owners are not encouraged to install such heating pads privately. If you connect the wires without permission, it will lead to short circuit of the wires, damage the electrical equipment and cause a fire.

Of course, some people regard the electric heating seat as a "chicken rib" and think that this product cannot be preheated in advance. When it is heated, the body will get warmer, so it is best to turn on the warm air. Nevertheless, in the eyes of car owners and prospective car owners, one less function is not as good as one more function, and the electric chair is still a symbol of "taste" and "comfort" and is sought after.
