Before we start, we must first understand what an airbag is. First of all, it is a system. The airbag system is a passive and safe protection system. It is used together with the seat belt to provide effective collision protection for the occupants. When a car collides, the car airbag can reduce the head injury rate by 25% and the face injury rate by about 80%. The working principle is that the airbag is opened between the first and second collisions, so that the occupant "pushes on the air", which has a buffering effect on the huge recoil caused by the collision, which is used to protect the front driver and the driver's head. With the device on the chest.
Its structure is mainly composed of an airbag sensor, an anti-collision airbag and an electronic control device. The driver side anti-collision airbag device is in the steering wheel; the passenger side anti-collision airbag device is generally mounted on the instrument panel.
In the car, there are generally buttons for starting the airbag device. In the event of an emergency, the airbag will automatically pop up, so when you are fine, don’t just press the button to let the airbag pop out. You have to pay for the new one. It is very dangerous to have no airbag protection in case of emergency.
In addition, the E-NCAP (European New Car Safety Appraisal Association) conducts new vehicle crash tests every year, and has relevant standards for airbags and anti-collision effects. The E-NCAP that puts people first is always very strict. , there will be tests for the following projects
These are collisions to test passive safety. In terms of vehicle design, E-NCAP also requires airbags. It requires airbag warning signs and passenger side airbags to close the switch.
However, a considerable part of the current models in China are not equipped with passenger side airbags, and there are only airbags on the side with single main drive, which mainly protects the driver and ignores the safety of other passengers. This situation is more common in cheaper versions. On the manual transmission model, if the traffic rules require that the front passengers must wear seat belts on the vehicle, one does not have airbags, and the other does not wear seat belts in accordance with relevant laws and regulations, then in case of a high-speed collision traffic accident, the passenger's personal body Security is hard to guarantee. Moreover, the E-NCAP crash test has a top speed of only 64Km/h. Most of the traffic accidents that collide on the highway are much faster than this speed. Therefore, in addition to the protection of the airbag, more drivers are required. Safety awareness of driving, pay attention to keep a reasonable distance from the front car, don't be too fast, don't be too slow, don't change lanes at high speed, do not do dangerous driving actions, etc.
And the more airbags are equipped, the better? It’s not always true that airbags can protect the occupants in the event of a violent collision, but it depends on the strength of the body. Otherwise, even a car with a steel frame will fall apart, even if it is an airbag, it will not take you from death. The hand is recovered, and in theory the airbag design life of the car is consistent with the service life of the vehicle. However, due to the lack of design standards, the actual life of airbags is not that long. Although there is no clear shelf life, the quality of the airbag is difficult to guarantee even after 8 to 10 years of use, even if it does not detonate. Therefore, from time to time to go to the 4S shop for airbag troubleshooting, regular maintenance can be used at critical moments
