How Does the Airbag Deployment Work?
2 Answers
Airbag deployment works as follows: sensors detect the intensity of a car collision and transmit the sensed signal to the controller. The controller receives and processes the signal from the sensors. When it determines that airbag deployment is necessary, it immediately sends an ignition signal to trigger the gas generator. Upon receiving the ignition signal, the gas generator rapidly ignites and produces a large amount of gas to inflate the airbag. Precautions for using airbags include: 1. Airbags must be used in conjunction with seat belts; 2. Maintain an appropriate distance from the airbag while seated; 3. Do not place objects in front of, above, or near the airbag; 4. Maintain good driving habits to ensure a certain distance between your chest and the steering wheel.
I've driven various types of vehicles and have considerable experience with how airbags deploy. When a vehicle experiences a severe collision, the onboard sensors quickly detect the impact force and then trigger the airbag module via electronic signals. The chemical reaction substances inside the module instantly generate a large amount of gas, inflating the airbag within tens of milliseconds to form a soft cushion that protects your head and chest from direct impact with hard objects. The entire process is incredibly fast—so fast that the airbag deploys before you can even react—but it only activates during severe frontal or side impacts. Remember that airbags work best when used in conjunction with seat belts. Avoid placing objects on the steering wheel that could block their deployment, and maintain a proper driving posture with your head not too close to the airbag area. After an airbag deploys, the entire system must be replaced. Regularly check the dashboard warning light to ensure it functions properly. These are all crucial safety details that help reduce injuries in accidents.
