After the computer is analyzed and confirmed, the computer immediately detonates an electric igniter (namely an electric detonator) in the airbag package to cause the airbag package to explode, and the process generally only needs about 50 milliseconds. After the igniter is ignited, the solid nitrogen particles are gasified rapidly, a large amount of nitrogen gas blows the air bag immediately, and under the strong impact force, the air bag is completely unfolded by opening the cover on the steering wheel.
Thus, an air cushion is formed in front of the driver and the passenger, when the driver and the passenger bump on the air bag, the nitrogen inside the air cushion is discharged from the small hole on the air bag due to pressure, thereby slowing down the bumping force and avoiding injuring the driver and the passenger.
Needless to say, an airbag plays an important role in protecting the safety of a driver and a passenger. However, the air bag is not perfect in the operating principle of the air bag, and if the air bag is not used properly, the air bag is likely to injure drivers and passengers. Because airbags are only a secondary safety system, consideration is given to protecting the user from the time the harness is fastened.
Although some automobiles are provided with a device for reminding passengers to fasten safety belts at present, the device and the automobile airbag system are mutually independent structures, namely, when the airbags act, the passengers are not necessarily in the state of fastening the safety belts, and the arrangement cannot enable the airbag system to fully exert the protection effect.
