Seat heating refers to the electric heating device in the seat. Generally appear on vehicles that use leather seats. Because the surface material of leather seats is low in winter, after the seat is heated, in the cold winter, sit down and wait for you. Leather chair. Most electric heating devices have the function of temperature adjustment.
In winter, many car owners find that the heating in the car starts slowly. Sitting on the leather seats, the entire back is cold, and the steering wheel is too cold to hold. How to warm up the body earlier before the car heater works? The editor learned during the visit that most high-end cars on the market are already equipped with seat heating. The electric heating device in the leather seat can heat up the entire seat surface, which will give the owner a warm and comfortable feeling in the cold winter. Feel. And those car owners who do not have heated seats can also install seat devices on their own in the car decoration and beauty market and auto parts stores. Is it safe to install a seat device like this? Insiders reminded that configurations such as electric heating seats cannot be installed on their own and should be selected carefully when purchasing.
Heated seats have good effect, the principle is the same as electric blankets
At present, many a-class cars with more than 150,000 yuan on the market are equipped with heated seats (such as German Mercedes-Benz, BMW, Audi, Volkswagen, Passat, Bora, etc.). But for most low-end models, the seat heating function has not been well popularized, so some car owners will purchase and install heated seats to achieve similar functions. The reporter visited several car decoration and beauty markets in Jinhua and found two types of heated car seats: one is an external seat device, a heated cushion inserted into the car cigarette lighter, and the price is 50-100 yuan; A built-in seat device that requires professional staff to install and modify the wiring in the car. The price is 200 to 500 yuan. The heating effect of these heated seats is quite good. When the switch is adjusted to high-end heating for 5 minutes, the temperature of the entire seat can rise by 15°C, and the temperature can be kept at a constant state for a long time by adjusting it to low-medium. The temperature range of the entire seat is maintained at 30~65℃.
In response to the issue of whether it is safe to install heated seats, the seller of an auto supplies store in the urban area said that the heated seats have built-in multiple sensors and protection devices to feel pressure and temperature. The circuit starts when the temperature is lower than 5°C, and automatically cuts off when the temperature is higher than 65°C. The seat cushion can automatically heat up when the pressure is pressed, and the induction stops heating up after the pressure disappears, that is to say, only the car owner sits in the position to heat the seat to start working, otherwise it will stop heating. "The principle of heated seats is similar to electric blankets. Now that electric blankets have been accepted by everyone, why not heated seats for cars?" The owner said that their products strictly follow the "Electric blankets, electric heating pads and similar flexible heating Special Requirements for Appliances", with 3 years of safe service life and symbol mark, as long as the owner strictly follows the requirements, there will be no danger.
Modified lines, consumers have many concerns
In a decoration shop in the city, the editor witnessed the entire process of installing heated seats: the staff first removed the outer seat cover of the seat, and then tore off the adhesive on the back of the carbon fiber heating pad and stuck it to the car On the seat and backrest sponge, connect the control switch and the dial with the connector, and then cover the seat cover, insert the temperature control switch into the original reserved hole of the car, so that you can connect the plug of the temperature control switch and the heating pad When the interface is connected, the heating cushion will start to generate heat as long as the car power is turned on. The main line, the ground line, the driving light line, and the ACC control line must be connected. Generally, it is not recommended that the car owner operate it by himself.
The installation of the built-in Heated Car Seat requires a modification of the circuit. Is the customer assured? The editor learned in the interview that many car owners have concerns about Heated Seat cushions, which are mainly manifested in: One type is questioning the safety of installing heated seats. Some car owners are afraid that the modified circuit will affect the original circuit, causing a short circuit or spontaneous combustion of the car body. There are also car owners who have installed heated seats, but still do not worry about heating them for a long time for fear of seat aging and leakage. Another type is concerned about the impact of the modified circuit on the car itself. Mr. Wu, who is on the sidelines, feels that the seat modification may affect the effective ejection of the side airbags and cause safety hazards.
Heated seats cannot be installed at will
At present, there are many brands of heated seats on the market, and some of them have simple packaging, lack of effective data signs, and quality is difficult to guarantee. Liu Mou from Jinhua No. 1 Automobile Decoration Department said that external heating pads are often directly connected to the cigarette lighter, so that the fuse is particularly easy to burn when heating; while other built-in automobile heating cushions are not directly connected to the cigarette lighter. The installation process The circuit needs to be changed, and the voltage limit of each car is stipulated. Once a new resistance is added, it may cause a short circuit of the car current, and even cause a fire. Therefore, it is not recommended for car owners to install such heating cushions privately. If you wire it privately, it will short-circuit the wires and destroy the electrical equipment, or cause a fire.
Of course, some people regard the electrically heated seats as "chicken ribs", thinking that the rouch cannot be preheated in advance. After it is heated up, the body will also warm up. It is better to turn on the warm air. Even so, in the eyes of car owners and prospective car owners, one less function is not as good as one more function. The electrically heated chair is still a symbol of "taste" and "comfort" and is sought after.
