The driver's seat airbag is an auxiliary configuration for the passive safety of the vehicle body, which is increasingly valued by people. When the car collides with an obstacle, it is called a primary collision, and the occupant collides with the interior components of the vehicle, which is called a secondary collision. When moving, "fly on the air cushion" to alleviate the impact of the occupant and absorb the collision energy, reducing the degree of injury to the occupant.
airbag protector
The driver's seat airbag is installed on the steering wheel. In the early days when airbags were just popularized, generally only the driver was equipped with an airbag. With the increasing importance of airbags, most models are equipped with primary and co-pilot airbags. It can effectively protect the head and chest of the driver and the passenger in the passenger seat at the moment of the accident, because a violent collision in the front will cause a large deformation in front of the vehicle, and the occupants in the car will follow the violent inertia. The front dive causes collision with the interior components of the car. In addition, the airbag in the driving position in the car can effectively prevent the steering wheel from hitting the driver's chest in the event of a collision, avoiding fatal injuries.
effect
principle
When the sensor detects the collision of the vehicle, the gas generator will ignite and explode, generating nitrogen or releasing compressed nitrogen to fill the air bag. When the passenger contacts the air bag, the collision energy is absorbed by buffering to protect the passenger.
effect
As a passive safety device, airbags have been widely recognized for their protective effect, and the first patent for airbags began in 1958. In 1970, some manufacturers began to develop airbags that can reduce the degree of injury to occupants in collision accidents; in the 1980s, automobile manufacturers began to install airbags gradually; in the 1990s, the installed amount of airbags increased sharply; and in the new century Since then, airbags are generally installed in cars. Since the introduction of airbags, many lives have been saved. Studies have shown that a frontal crash of a car with an airbag device reduces the death rate of drivers by 30% for large cars, 11% for medium-sized cars, and 20% for small cars.
Precautions
Airbags are disposable products
After the collision detonates, the airbag no longer has the protective ability, and must be sent back to the repair factory for a new airbag. The price of airbags varies from model to model. Reinstalling a new airbag, including the induction system and computer controller, will cost about 5,000 to 10,000 yuan.
Do not place objects in front of, over or near the air bag
Because the airbag will be deployed in an emergency, do not place objects in front of, above or near the airbag to prevent the airbag from being ejected and injuring the occupants when it is deployed. In addition, when installing accessories such as CDs and radios indoors, you must abide by the manufacturer's regulations, and do not arbitrarily modify the parts and circuits that belong to the airbag system, so as not to affect the normal operation of the airbag.
Be more careful when using airbags for children
Many airbags are designed for adults, including the position and height of the airbag in the car. When the air bag is inflated, it may cause injury to children in the front seat. It is recommended that children be placed in the middle of the rear row and secured.
Pay attention to the daily maintenance of airbags
The instrument panel of the vehicle is equipped with an indicator light of the airbag. Under normal circumstances, when the ignition switch is turned to the ACC position or the ON position, the warning light will be on for about four or five seconds for self-checking, and then go out. If the warning light stays on, it indicates that the airbag system is faulty and should be repaired immediately to prevent the airbag from malfunctioning or accidentally deploying.
