Air bags can save people, but they can also hurt people!
If we look at things from the point of view of dialectical materialism, there are two sides to everything. There is no absolute good, there is no absolute bad. The same is true of "airbags", which are not necessarily safe, but also have drawbacks. We all know the role of airbags, that is, the vehicle pops up when a collision occurs to protect the safety of passengers. However, the ejection of the airbag has a trigger condition, and it will not be ejected under any circumstances. And the role of the airbag is to protect the safety of passengers, if the passenger is not injured, then even if the airbag is not ejected in the accident, is there no problem?
【1】Under what circumstances will the airbag pop out?
1. In the event of a traffic accident, the relative speed needs to be greater than 50km/h, and the acceleration of the opposite direction at the moment of collision is more than 40g to reach the condition of opening the airbag.
2, also need to be determined according to the angle of the car collision, only the impact near the airbag sensor, the airbag will be opened, about 60 ° between the left and right sides of the car.
3, need to hit the wall or obstacle, the airbag will be opened, if it is used to hit the airbag sensor, it will not cause the airbag to open. Because it has a certain relationship with the speed of the vehicle.
Therefore, the airbag is a configuration that only triggers under certain conditions, and if it is understood simply, not all traffic accidents will eject the airbag. But accidents that eject airbags are big accidents.
[2] Visually detect a big accident, but maybe it is a small accident?
Not long ago, such a thing happened, a Hongqi H9 owner suffered a traffic accident, the front of the car has been very serious damage, from the picture, the front bumper has been broken, the entire hood damage is also very serious. And the insurance company gave a maintenance price list of 160,000 yuan. It is reasonable to say that such a collision accident is already a big accident for many people. But at the time of the accident, the airbags did not pop out, and the passengers in the car were not injured.
Later, after third-party identification, the forward acceleration signal of this accident was less than 32 kilometers per hour in the calibration stage, and the columnar acceleration signal was not enough to ignite the front airbag.
In simple terms, the vehicle looks as if the collision is very serious, but in fact, the signal of forward acceleration is less than 32 kilometers per hour, which means that the accident has not yet reached the level of triggering the air bag.
[3] Vehicle safety should be based on human safety, not on whether the airbag is opened
In some accidents, many people use the airbag to determine whether the vehicle is safe or not. I don't think it's reasonable either. Vehicle safety should be based on human safety, not on whether the airbag is opened. In this traffic accident, the airbag of the Hongqi H9 was not opened, but the passengers in the car were not injured. Therefore, the safety of the most critical "people" is guaranteed.
So since people are safe, what is the point of opening the airbag or not? When the airbag is opened, is it safe for the person? Not necessarily, because the moment the airbags bounce off, they will also cause a collision on the human face.
Assuming that in this accident, the passengers in the Hongqi H9 car were injured, and the airbags did not pop out, then it is certain that there is a problem with the airbags of the vehicle. Since the passengers in the car were not injured, it makes little sense to investigate whether the airbags were bounced off.
