What is the round disc inside the steering wheel?
2 Answers
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.
