Explanation of terms of driver's seat airbag
The driver's seat airbag is all installed on the steering wheel. In the early days, when airbags were just popularized, generally only drivers would be equipped with airbags. With the increasing importance of airbags, most models are equipped with primary and secondary airbags. At the moment of the accident, the head and chest of the driver and the co-pilot can be effectively protected, because the violent collision in front will cause great deformation in front of the vehicle, and the occupants in the vehicle will dive forward with the help of this violent inertia, resulting in collision with the internal parts of the vehicle. In addition, the airbag in the front driving position of the vehicle can effectively prevent the steering wheel from pushing the driver's chest in the event of a collision, thus avoiding fatal injuries.
Working principle of driver's seat airbag
When the sensor detects a vehicle collision, the gas generator will ignite and explode to generate nitrogen or release compressed nitrogen to fill the airbag. When the passenger touches the airbag, the collision energy will be absorbed through buffering, thus protecting the passenger.
As a passive safety device, the protective function of airbag has been widely recognized. The first patent on airbags began in 1958. 1970, some manufacturers began to develop airbags that can reduce the degree of occupant injury in collision accidents; In 1980s, automobile manufacturers began to install airbags step by step. In 1990s, the number of airbags increased sharply. After entering the new century, cars are generally equipped with airbags. Many people's lives have been saved since the appearance of airbags. The research shows that when a car with airbag device collides head-on, the driver's death rate of large cars is reduced by 30%, that of medium-sized cars by 1 1%, and that of small cars by 20%.
