Is the airbag popped up? wrong! ! !

It is known that the airbag is a passive safety protection system that provides effective crash protection for occupants in emergency situations. However, the gap between the steering wheel is so small. How does the airbag pop up in an instant? In fact, the airbags did not spring from the gaps in the steering wheel, but they were "broke out." Then the question came again. How did the airbag get out of the box? Listen to Xiao Bian slowly.

Actually, the center of the steering wheel that we usually see, and the position in front of the co-pilot are generally smooth, and everyone knows that there is a well-designed line under this smooth surface. At the location of that line, the thickness of plastic is generally only 0.5mm or even thinner. This is the legendary “tear seam” and is the key to airbag design.

However, the airbag did not pop out of this tear seam, which was summed up from the accident caused by the airbag. According to statistical results, the accident is not a failure of the airbag itself, but occurs when the airbag is working properly. Originally, airbags were generally blown open. Therefore, the metal fragments that were generated when the airbags were blown were wounded. It was these fragments that cut people instantly!

Someone may have to ask, is the airbag not used to protect safety, how could such a large lethality? In fact, look at its working principle to know, airbag = "buffer big balloon" = impact + sensor + ECU trip computer + electric burst tube + powder powder + gas generating agent + airbag. Therefore, the so-called "airbag pop-up" is actually blown out. The intensity of this kind of instant blasting can be imagined, and the strength must be small.

Although Xiao Bian said it was a bit serious, but I have to remind everyone, do not blindly believe the role of airbags! With any security issues, what really matters is the seat belt. To know that the full name of the airbag is SRS Airbag (Supplemental Restraint System), that is to say "seat belt auxiliary protection system", pay attention to its focus is auxiliary. Therefore, we must remember to use the seat belt correctly so that the airbag can play a normal role of protection, rather than a counter effect.

The United States had planned to use airbags instead of seat belts and found that the crash still hung. Therefore, the more airbags are not necessarily safer, the “tear seams” are determined after millions of experiments. When plastics and metals are “fried out”, they cannot fly everywhere.

Editor's Note: The last Xiaobian would like to say is that the airbag has a shelf life, it is recommended that every 1 to 20,000 kilometers after going to the 4S shop to check once. At the same time, airbags are also disposable products, and new airbags must be replaced promptly after detonation.
