Airbags are extremely important to use precautions to know early
Car safety is one of the most concerned issues for riders. Car airbags are also very important. Many riders are very easy to ignore the problem of airbags. Here are some of the feelings that Xiaobian has arranged for the riders. Some related issues with car airbags. When consumers buy new cars, they are often concerned about safety issues. Airbags are a key issue that consumers must ask during the car purchase process. Many brands will write the number of airbags in conspicuous places in the product brochure. When the sales are introduced, the airbag device is inevitable. As early as 50 years ago, American John Hertlet invented the airbag. In 1952, he developed the idea of ​​an airbag after an accident. He used his daughter’s ball like a test material with his wife. As the driver, the bottle is continuously subjected to impact test in the laboratory. Finally, the rubber-coated airbag with gas can slow down the glass cracking. In the absence of airbag protection, the glass bottle is basically broken by 100%. Under the impact of the air like a ball, the fragmentation rate was only 24%. Two months later, John Hertlet gave his idea to GM, and the design on the drawing was in front of the steering wheel. An inflatable ball, filled with a ball in 2 seconds through a high-pressure air pump mounted on the front of the car, although this is the prototype of the airbag, but in the real crash, 2 seconds full of gas does not protect pedestrians, 1953 universal airbag installation In the steering wheel, the trigger end of the high-pressure air pump was replaced by a sensor. After several years of testing, the airbag was able to rush out in 0.63 seconds. With the development of the automobile industry, nowadays With the popularity of airbags, some of the drawbacks have gradually emerged in the process of use. Many customers just know that airbags can reduce the damage caused by car accidents, but ignore how to use airbags correctly. What do you need to pay attention to when using airbags? The airbag belongs to the passive safety configuration of the vehicle and bounces in the event of a collision of the vehicle to avoid a secondary collision or to be thrown away from the seat when the vehicle rolls over. We don't want to use it only in the configuration of the crisis, but you still need to know the relevant precautions. Owner story Ms. Liang finally bought the favorite seat cover, but she was reminded when she went to the 4S shop for maintenance: the seat cover she bought was not suitable for her own model. After the installation, it will affect the airbag pop-up. The staff suggested that she replace it as soon as possible. Ms. Liang did not understand. When I bought a seat, I said that all kinds of models are common. Why does it affect the use of airbags? Besides, most of her cars are used in urban areas. Should she use this airbag configuration? FAQ Airbags are classified According to experts, most of the airbags currently deployed on vehicles are mainly front airbags, side airbags and side air curtains. There are two standard airbags on the mid- and low-end cars, which are usually placed in front of the driver's seat and the first officer's seat to protect the front passenger's brain and chest when the vehicle hits a violent impact. In some mid- to high-end models, there are usually four airbags. In addition to the front position of the driver's seat and the passenger's seat, the side door also has two airbags. Some high-end cars will have more airbags. For example, Volvo, which is known for its safety, is equipped with six airbags and 18 air curtains on the flagship model. In addition to the front and rear front and rear driving positions in the front and rear seats, there are Two airbags, 18 air curtains distributed at the front and rear windshield and side windows provide the most effective protection against impact from all directions. Airbag popping is "conditional" The airbag is an auxiliary protection device for the airbag system. It is made of rubber-lined special fabric nylon, which is filled with harmless helium when it is opened. In the event of a collision, the airbag inflates approximately 0.03 seconds. The very fast inflation speed ensures that the airbag is in place when the passenger's body is restrained by the seat belt and the head is still moving forward. Since the airbag can be inflated at a speed of up to 320 km/h, if the occupant's riding posture is incorrect during a collision, it will cause serious injury to the human body. In order to ensure that the airbag is opened at the appropriate time, the car manufacturer has specified the detonation conditions of the airbag, and only when these conditions are met, the airbag will explode. However, if the airbag is not detonated, the airbag will not open. According to reports, the airbag needs a certain angle and strength to open. Generally speaking, the position where the car collides is about 45 degrees to the left and right of the front of the vehicle, and the airbag can be opened when the speed is higher than 25 kilometers. In the collision of the car, the main force is the bumper and the body longitudinal beam. In order to cushion the impact force during the collision, the front part of the vehicle body is mostly designed with a collision buffer, and the stiffness distribution of the body is also uneven. For example, when a car has a drilling rear-end collision with a truck without a rear guard, or a rollover accident occurs after the car collides with the guardrail, or a side collision occurs, such an accident often has no direct impact on the front of the vehicle body, mainly the upper part of the vehicle body. Collision with the side, the rigidity of the collision body part is very small, although the cabin is greatly deformed, causing injury or death of the occupant inside the vehicle, but the airbag cannot be opened because the collision position is wrong. Especially in a side collision, if the side airbag is not configured, the primary and secondary airbags cannot be detonated because they cannot reach the detonation condition. The above is some of the related issues about car airbags compiled by the editors for the riders. I hope that the riders can understand and remember.
