What does airbag mean in a car?

Airbag in a car refers to the safety airbag, which is usually marked on the steering wheel and the interior panel of the passenger seat, indicating the presence of airbags in these locations. Some door panels and seats also have such markings, indicating that these components are equipped with airbags as well. An airbag is a high-strength fabric bag that is usually folded flat and stored within the interior decoration of the vehicle. When the vehicle experiences a collision, the impact sensor detects the accident and activates the airbag. The airbag will rapidly inflate, serving as a cushion between the occupants and the vehicle, preventing injuries caused by impact with the vehicle's structure or broken glass and other objects.
An airbag is a safety airbag, a crucial life-saving device in vehicles. I remember last time when I accompanied my friend to the repair shop, the technician specifically emphasized its importance. It's installed behind the steering wheel and dashboard, as well as near the doors and seats. When the sensors detect a severe impact, the airbag deploys in less than 0.1 seconds, instantly inflating to cushion you from hitting hard surfaces. Most cars now come standard with six or more airbags, and some high-end models even have them near the knee area. However, it's important not to hang objects on the airbag cover, as they can become dangerous projectiles when deployed in an emergency. During vehicle maintenance, the airbag system should be checked—if the yellow warning light comes on, it needs immediate attention. Airbags plus seat belts form a complete protection system, a principle I've firmly believed in throughout my more than ten years of driving.
The airbag you asked about is actually the safety airbag, which my driving instructor specifically covered during my license training. It's hidden like a balloon in the steering wheel and in front of the passenger seat. During a severe collision, the computer receives signals from sensors and triggers a chemical reaction to generate a large amount of nitrogen gas, causing the airbag to instantly inflate and cushion you from hard objects. I remember watching a car crash video where the airbag deployed, leaving the passenger with a logo imprint on their face but otherwise unharmed. However, when installing a child seat, be careful not to place it in the front seat, as the force of the airbag deployment can be harmful to children. Modern airbags are quite intelligent—they can determine the level of inflation based on the impact force and work in tandem with seatbelt pretensioners. It's recommended to have the airbag system checked every five years, as it's a matter of life and safety.
