What is the round disc inside the steering wheel?

The round disc inside the steering wheel is the airbag. Here is relevant information about airbags: 1. Introduction: The airbag is installed in the center position of the steering wheel. Nowadays, the horn buttons of many car models are also placed in the center of the steering wheel, though a few models position them at the three or nine o'clock positions. If the vehicle suffers a severe impact, the airbag will deploy from the center of the steering wheel. 2. Activation Conditions: To ensure the airbag deploys at the appropriate time, automakers have established specific activation criteria. The airbag will only inflate when these conditions are met. Even in some traffic accidents where passengers suffer head injuries or life-threatening situations, and the vehicle is nearly totaled, the airbag will not deploy if the activation conditions are not satisfied.

As a seasoned long-distance driver, I know that the round disc inside the steering wheel is actually the airbag system. It’s hidden beneath the steering wheel cover and consists of a disc containing the airbag cushion and inflator. I once experienced a car accident where the airbag deployed instantly, protecting my head and chest from serious injury. This device uses sensors to detect impact force and inflates within milliseconds during a collision to cushion the blow. However, it’s crucial not to place any objects on it, such as phones or decorations, as they can become dangerous projectiles if the airbag deploys. I recommend developing good habits: check the airbag indicator before driving and have the sensors and wiring inspected at a repair shop every year or two to ensure everything is functioning properly. Safety is the top priority when driving, and this small disc can be a life-saving barrier in emergencies.

When I first bought a car, I was also curious about what that round disc on the steering wheel was. After researching online, I found out it's the core component of the airbag. The airbag is made of tough fabric and inflates into a large cushion upon deployment, providing protection against collisions and impacts. I once tried disassembling an old steering wheel and saw compressed gas and an electronic controller inside, connected to the vehicle's crash sensors. While driving, the area around the disc must never be covered, as it could prevent the airbag from deploying, which is very dangerous. I also learned that airbags were invented decades ago and have now become standard safety equipment. Remember, regular maintenance can extend the airbag's lifespan—for example, reminding technicians not to tamper with it during car washes or repairs. Knowledge is protective power; understanding more about car details can make daily driving safer and more reassuring.

I drive to work every day and pay special attention to the round disc on the steering wheel, which is the airbag. It serves as a protective device, rapidly inflating during an accident to safeguard the occupant. When using it, be careful not to obstruct it, such as by placing stickers or objects on it. Maintenance is simple—just regularly check the sensors and avoid parking the car in high-temperature environments for extended periods. Safety always comes first; this small component is crucial.
