The airbag system is a passive safety protection system. It is used in conjunction with seat belts to provide effective crash protection for passengers. When a car collides, the airbag can reduce the head injury rate by 25% and the facial injury rate by about 80%.
Sort by quantity Single airbag, double airbag The number of standard airbags in domestically produced mid-range and low-end cars is 1-2. Generally, there is one in the driving and co-pilot positions of the vehicle, which is used to protect front members from the chest and brain during a violent collision Effective protection of the Ministry.
Four airbags In some mid-range B-class cars, four airbags are generally installed in addition to the two in the driver’s and co-pilot positions, and two are also installed in the side doors. Effectively cushions powerful impact from the front and sides.
Multi-balloon In some high-end cars, as well known for its safety, the Swedish Volvo sedan is equipped with 6 airbags and 18 air curtains in its flagship model. They are located in the front and front driver’s seats in the car, two on each side of the front and rear doors 18 air curtains are distributed at the front and rear windshields, and the side windows provide the most effective protection against impacts from all directions.
Airbag seat belt Airbag-type seat belts that prevent car rebound injuries and deaths, formerly known as airbag-type safety belts that prevent car airbag rebound injuries and injuries, are also known as airbag-type safety belts. A Peugeot airbag device is provided on the shoulder and the entirety of the vehicle safety belt. The safety belt combines the characteristics of traditional seat belts and airbags to provide passengers with a higher level of collision safety protection. This technology reduces the passenger’s head, neck and chest injuries during the accident. The use of airbag-type seat belts further enhances the vehicle’s innovative safety facilities, and is a good news for children and the elderly. This airbag type seat belt, when it encounters an unexpected situation, the seat belt will instantly expand into an airbag shape, and its impact relief effect is 5 times that of the traditional seat belt; first, the large area can effectively reduce the head and neck Shake, the second is to have a certain reaction force when the airbag is inflated, which can reduce the rib fractures, internal organ damage and bruises that are prone to passengers in a car accident.
Side airbag Side airbags are installed on the outside of the seat to reduce injuries caused by side impacts. Many manufacturers’ models come standard with side airbags for the front two seats, while few models with rear side airbags.
Knee airbag Most models are only equipped with main and co-pilot airbags, side airbags, etc. In fact, when the vehicle actually experiences a frontal collision, the underside should be more protected, and the distance between the lower knee and the center console is the shortest, which is the easiest The site of the fracture injury. The knee airbag is used to reduce the occupant’s knee injury to the passenger’s knee during the second collision. The airbag at the knee is located in the front driver’s seat. Once opened, it can effectively protect the lower limbs of the rear passengers, which can also relieve the frontal impact from frontal collision.
Head airbag The head airbag, also called a side air curtain, pops up to cover the windows during a collision to achieve the effect of protecting passengers. The head airbag mainly protects the head of a passenger in a side collision. B-pillar sides, window panes, and even seat belt side support buckles can all become killers in car accidents. Then the head airbag will separate members from these things. The head airbag is installed in the curved steel beam on the roof, usually running through the front and back, and controlled by the lateral acceleration sensor in the body. When the lateral acceleration is greater than the normal value and reaches a dangerous value, the explosion will be controlled. It has a good personnel protection function for serious accidents such as side collisions and rollovers.
By protection object ● Front airbag: Driver Front Airbag (DA), ● Passenger Front Airbag (PA) ● Side airbag: Front Side Airbag (FSA), ● Rear Side Airbag (RSA) ● Side Tubular or Side Curtain Airbag ● Knee Airbag
The airbag can evenly distribute the impact force on the head and chest, preventing fragile passengers 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. Even without a seatbelt, anti-collision airbags are still effective in reducing injuries. According to statistics, in the event of a frontal collision with a car equipped with airbags, the degree of injury to passengers can be reduced by up to 64%, and even 80% of them are not wearing seat belts! As for the collision from the side and the back seat, it still depends on the function of the seat belt. In addition, the volume of the airbag when it bursts is only about 130 decibels, which is within the tolerable range of the human body; 78% of the gas in the airbag is nitrogen, which is very stable and non-toxic, which is harmless to the human body; the powder brought out during the burst is to maintain the airbag Lubricating powder that does not stick together in the folded state is not harmful to the human body.
