What Must Airbags Work With to Provide Protection?
1 Answers
Airbags must be used in conjunction with seat belts to effectively provide protective measures. Without the use of seat belts, airbags alone are ineffective. Assuming that the combination of airbags and seat belts provides 100% safety, seat belts contribute 70% of the protection, while airbags contribute 30%. Therefore, airbags and seat belts must work together to fully maximize their protective effects. How Airbags Work: When a vehicle is involved in a collision while in motion, the airbag sensor first 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 data. If the conditions for airbag deployment are met, the drive circuit sends an activation signal to the gas generator in the airbag assembly. Once the gas generator receives the signal, it ignites the gas-producing agent, generating a large volume of gas. This gas is filtered and cooled before entering the airbag, causing the airbag to rapidly inflate within milliseconds, breaking through the cushion. An elastic cushion forms in front of the driver or passenger, which then deflates and contracts to absorb the impact energy. This process effectively protects the head and chest, preventing or reducing the severity of injuries.
