Under What Circumstances Do Airbags Deploy?
2 Answers
Airbags deploy under the following conditions: when the vehicle speed exceeds 50 kilometers per hour; the point of impact must be near the sensor; and the object being struck is a rigidly fixed item. Introduction to Airbags: The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%. How Airbags Work: The principle of airbags is that when a collision occurs while the car is in motion, the airbag sensor receives the impact signal. If the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic controller. Upon receiving the signal, the electronic controller compares it with its pre-stored signals. If the conditions for airbag deployment are met, the drive circuit sends a start signal to the gas generator in the airbag module.
Airbags primarily deploy when the vehicle experiences significant impact, such as frontal or side collisions at speeds exceeding 25 kilometers per hour. Sensors are distributed at the front, rear, and sides of the vehicle to detect sudden deceleration or direct impact. Only when the impact is strong enough do the sensors trigger the explosive inflation of the airbags, aiming to protect the occupants' head and chest within milliseconds. Having driven for decades, I've learned that airbags don't activate in minor scrapes, like low-speed reversing into a tree; they only deploy in high-speed accidents, such as rear-end collisions or rollover risks. Ensuring seat belts are worn is crucial, as airbag deployment without them could cause harm. Regular checks of the safety system are also vital—if the airbag light comes on, get it fixed promptly to prevent accidental deployment. In reality, airbag design is highly intelligent, factoring in angle and impact severity to ensure they function only in genuine danger.
