An airbag is a safety system designed to protect vehicle occupants from secondary collisions during an accident. It prevents direct impact between passengers and interior components such as the steering wheel or instrument panel, significantly reducing injury. When a vehicle collides at speeds over 25 km/h, sensors detect the force of impact and determine whether to deploy the airbag. The inflator rapidly fills the airbag to absorb the shock and protect the occupant. This entire process begins within 0.04 seconds and completes within 0.06 seconds. The airbag cover is a critical safety component that protects the airbag module and maintains a clean interior appearance under normal conditions. In the event of a collision, it ensures the safe and precise deployment of the airbag toward the occupant.
