When an airbag is in a car accident, it will pop out within milliseconds to reduce the impact injury of the occupants of the car.
However, because the airbag detonates extremely quickly, the ejection speed can reach 300km/h, and if it is injured by the airbag, it can also cause serious damage.
A few days ago, photos uploaded by netizens showed that because the airbag is under the logo cover in the center of the steering wheel, when the airbag pops out, it will bounce off the cover.
Unfortunately, the cover plate that was ejected hit the body of the people in the car again, because the impact was huge, and even the logo logo was printed on the body, and now netizens also know that this car is Beijing Hyundai.
In fact, the impact of the airbag cover plate that was ejected is also a high incidence incident, before, there was also a Honda car owner, who was "punched in the face" by the cover, and more exaggeratedly, directly printed a Honda "logo" on the face, which is simply incredible, from which you can also indirectly feel how powerful the airbag explosion is.
In addition, from the principle composition of airbags, we can understand how powerful they are.
After the collision sensing of the vehicle receives the car accident signal, it will lead to a gas bladder inflator, and after the device catches fire, the ignitant is propelled by sodium nitride and oxidant, which quickly generates a large amount of nitrogen and fills it into the airbag. And this ignition device is explosives, which is also the main reason for the huge power of airbags.
According to calculations, if the car is driving at a speed of 60km per hour, the sudden impact will make the vehicle stop within 0.2 seconds, and the airbag will pop out at a speed of about 300km/h, and the resulting impact force is about 180 kg, and it is difficult for the head and neck of the human body to withstand such a high-force impact.
Therefore, if the airbag does not pop up at the right angle, timing and force, the life-saving device will become a life-threatening device, especially for children, because the seat belt cannot fix it on the seat, so it must not be allowed to sit in the front row of the vehicle and be threatened by the airbag.
