What is the function of airbags?
2 Answers
Airbags are primarily designed to prevent injuries caused by collisions between vehicle occupants and interior components during a car crash. Below is relevant information: 1. The protective principle of airbags is as follows: When a car experiences a certain level of impact force, the airbag system triggers a chemical reaction similar to the detonation of a small explosive. The airbag, hidden within the vehicle, rapidly inflates and deploys, positioning itself between the occupant and the interior components before impact occurs. Upon contact with the airbag, the airbag begins to deflate through small holes on its surface, cushioning the impact and reducing the force exerted on the body. This ultimately minimizes the occupant's injuries. 2. The airbag system can only be inspected using an airbag diagnostic tool. It should not be tested with a test light, voltmeter, or ohmmeter, as the airbag can be accidentally triggered by high test currents. As a critical safety component, airbags protect drivers in the event of an accident. Therefore, regular maintenance is essential. If any issues are detected, even minor ones, it is advisable to visit a 4S store or repair shop for inspection and servicing.
The airbag is primarily a device designed to prevent serious injuries during a car crash. It rapidly inflates and deploys in the event of a collision, acting like a large cushion to absorb the impact on your body, especially critical areas such as the head and chest. I have personally witnessed airbags saving lives—without this cushioning effect, hitting the steering wheel directly could even result in broken ribs. The working principle of an airbag involves sensors detecting a severe impact, which then triggers a chemical reaction to generate a large volume of gas, all happening at an astonishing speed. However, it's important to note that airbags must be used in conjunction with seat belts to function effectively; their performance is significantly reduced when used alone. Nowadays, high-end models also feature side airbags installed in doors or seats to provide all-around protection for various parts of the body. Every time the vehicle starts, the airbag light on the dashboard briefly illuminates for a self-check, ensuring it functions properly when needed most.
