What a painful understanding of car knowledge-airbags you don’t know

hint:

seat beltSince its invention, it has provided drivers and passengers with a very important protective effect, but in the event of a strong collision, the head and chest of the front seat driver are still vulnerable to injury, soairbagWas born. As we all know, the airbag is very effective in cushioning the impact, it will fully absorb part of the impulse of the driver and passengers, and assist the seat belt to protect the driver and passengers. As a result, more airbags appeared on the head and sides of the driver and passengers.

Speaking of this, you might think that the airbag is filled with gas, and it should be soft and gentle. You don’t understand it. Once you know its pop-up principle, you will find that the airbag is actually not gentle at all. very dangerous!

So where did the airbag pop out from?No need to studysteering wheelOn the stitches, the airbag did not pop out from the stitches, but "exploded" out!

To be precise, the airbag is instantly inflated by explosives inside, breaking through a pre-designed weak area on the steering wheel or dashboard.

However, this weak area is also carefully designed by engineers. There will be a line under the smooth surface. The thickness of the plastic is generally only 0.5mm or even thinner. This line is called a tear crack and is the key to airbag design.

If the vehicle is hit by a frontal impact without a seat belt and the airbag is triggered, the airbag that pops up instantly will give you a 180kg uppercut to your leaning body, which will directly send you to the top. Therefore, airbags and seat belts are a pair of conjoined brothers and cannot be divided!

So the question is, what is the experience of being hit by an airbag in the face?

The editor has no personal experience, but the editor has collected some lessons learned from old drivers:

"I was rear-ended, and I was okay, but the airbag popped out to hit the face and lost a tooth."

"It was dumbfounded in an instant. Then I couldn't find the glasses..."

"It's like a heavy slap, but I was too scared at the time and forgot the pain."

"It's so painful! My head is a big bag!"

"I have a nosebleed, do you think it will feel better?"

"When something went wrong, I subconsciously put my arms in front of my head, and the arms that were stricken by the air sacs covered a big head and a big bag."

"The two cars collided, the co-pilot was tied up, and the other was not tied, but it was not tied. The lung pneumothorax was hospitalized for 20 days. The eye of the tied pneumothorax was blown up by the airbag, and the person was okay. seat belt."

Finally, the editor reminds everyone that it is of course a good thing to drive safely, but if there is a problem with the airbag, you must deal with it immediately and don't delay!

Because the manufacturer can't guarantee that the airbag can still be used normally after ten years, so if you have a car that has been used for ten years, you need to replace the airbag if you continue to drive it.
