The airbags are not unfamiliar to riders and are now basically the standard for every car. However, when it comes to airbags, the first reaction of many people is: Is it safe to use airbags in the end? This phenomenon is not surprising. It is only in recent years because airbags have become more and more difficult. . Well, after reading today’s article, I believe that everyone will have a comprehensive understanding of airbags. What is an airbag? The airbag system is a passive safety protection system that works with seat belts to provide effective crash protection for the occupants. Is airbag safety insecure? Through a large number of simulations and accident statistics, it is shown that in all possible fatal car accidents, approximately 45% of lives can be saved if seatbelts are properly used; this ratio rises to approximately 60% if seatbelts and airbags are used simultaneously; if only With airbags, this percentage will not exceed 5%. This is enough to show that the safety of airbags is relative. If airbags are used alone, it is a time bomb. The data shows that a car is traveling at a speed of 60km/h. When it encounters a sudden impact, the airbag will pop up at a speed of more than 200km/h. The resulting impact force is about 180kg. When the airbag is inflated, a huge impact force directly hits the occupant's face. If the occupant does not wear a seat belt, it directly hits the airbag that is exploding. It can even cause death! Therefore, whether or not the airbag is safe must be determined in conjunction with safety. Airbag defects As one of the effective measures to improve the safety of automobiles, airbags have attracted more and more attention. In some actual collision accidents, it has been proved that the airbags do have the effect of reducing the casualties of the occupants, but some problems have also been discovered. The problems with airbag use are: The airbag may open at very low speeds. When a car is driving at a low speed and a collision occurs, the occupant and the driver can fasten the seat belt, and no airbag protection is required at all. If the airbag is deployed at this time, it will cause unnecessary waste, and it may even increase the crash damage due to deployment of the airbag. Initiation of airbags can cause injuries to occupants. When the airbag system starts, the airbag cover will be flushed and the inflation will be carried out in an instant, which may cause impact to the occupant; the hot gas generated may also burn the occupant and the driver. According to calculations, if the car is traveling at a speed of 60 km/h, a sudden impact will cause the vehicle to stop within 0.2 seconds, while the air bag will pop up at a speed of about 300 km/h, and the resulting impact force will be about 180 kg. This is difficult for the vulnerable parts of the body such as the head and neck. Especially when the passenger deviates from the seat or the seat is a child's ride, the activation of the airbag system not only fails to provide the necessary protection, but also may cause some damage to the occupant. The airbag does not pop up. Now that pop-ups are mentioned, one cannot fail to mention that the airbags do not pop up: The first thing to say is the trigger point. No matter how severe the collision is, it does not hit the trigger point of the airbag. The airbag cannot be ejected anyway. Secondly, when hitting a stopped vehicle of the same class at a speed of 50km/h or less, the airbag may not start, hitting a pole that will not be broken at a speed of about 30km/h, and crashing into a truck, etc. Airbags may not start. Finally, frontal airbags are generally not activated at a speed below 20km per hour when hitting thick concrete walls, being hit by a side impact, being hit from behind, being rolled over, flipped over, etc. Some misunderstandings about the use of airbags Misunderstanding 1: If the seat belt is not attached, the airbag will not open? Some riders believe that airbags will not be opened without a seat belt. In fact, this is a misunderstanding. First, if you remove the deflagration pre-tensioned seat belt, there is no data cross-linking between the general seat belt and the bus in the car. Second, according to the general manufacturer's settings, the airbags will develop under conditions such as the deformation and acceleration of the collision. The state of the seat belt is not considered at this time, so whether the airbag is opened or not is not directly related to the seat belt. Misunderstanding 2: Put things in the control panel Many riders like to create a feeling of home in their own car, putting a lot of things in the car, but sometimes it will bring some hidden dangers, such as putting some 7788 in the center console, once In the event of an accident, the airbags were opened, and these things would be photographed with the open airbags on the front passenger's face. If a cloth doll were to be returned, it would be frustrating if it were a perfume bottle. Airbag use precautions 1. The airbag should be inspected periodically. Although it is not a consumable part and it is not prone to failure, it is best to check every one to twenty thousand kilometers. 2. Do not place objects around and above the airbag to prevent it from being ejected when the airbag pops open, causing injury to the inside of the vehicle. 3, children do not sit in the co-pilot, or prevent child safety seats, if you really want to put him (her) on the vice driving, provided that your co-pilot airbag can be locked independently, otherwise the child is prohibited from appearing in the co-pilot. 4, the driving posture must be correct, back affixed to the back, hands steady steering wheel, face and the steering wheel to maintain 35-40 cm distance, and fasten the seat belts. 5, for some expectant mothers, wearing seat belts should pay attention to matters needing attention, the diagonal belt of the seat belt must be placed under the chest, leaving no buffer room, and down from the chest along the stomach. The waist belt must be in the lowest position of the raised abdomen, not across the front abdomen. In particular, the latter approach is particularly important because if a collision occurs in the vehicle, the seat belt slides in the front of the abdomen, which can cause harm to pregnant women and the fetus. 6, airbags are disposable products, once this thing pops up, it can only be replaced. However, Xiaobian hopes that the car of the riders will never return to the new airbag. Although current car manufacturers use airbags as an important selling point to promote, airbags are an absolute double-edged sword that can provide good protection when used properly, and the airbags cannot be opened. Or when it is used improperly, it will have side effects. Again, all safety equipment is auxiliary, and only safe driving is the most important guarantee for ensuring safety.
