Airbags can evenly distribute the impact force on the head and chest, preventing the vulnerable passenger’s flesh from directly colliding with the body, greatly reducing the possibility of injury. Airbags can indeed effectively protect passengers in the event of a frontal impact, and even if they are not wearing seat belts, anti-collision airbags are still enough to effectively reduce injuries. According to statistics, when a car equipped with airbags has a frontal collision, it can reduce the degree of passenger injury by as much as 64%, and even 80% of the passengers are not wearing seat belts! As for the collision from the side and the rear seat, it still depends on the function of the seat belt. In addition, the sound volume when the air bag explodes is only about 130 decibels, which is within the tolerable range of the human body; 78% of the gas in the air bag is nitrogen, which is very stable and non-toxic, and is harmless to the human body; the powder brought out when it explodes is to maintain the air bag. Lubricating powder that does not stick together in the folded state and is also harmless to the human body.
