The purpose of an airbag is to cushion and protect occupants in the event of a collision or sudden deceleration. It works in conjunction with seat belts to provide a secondary level of protection. When a collision occurs, the airbag rapidly inflates with gas and forms a cushioning barrier between the occupant and the hard surfaces of the vehicle, reducing the risk of injuries to the head, chest, and other body parts. The primary function of an airbag is to prevent occupants from forcefully hitting the steering wheel, dashboard, or windshield and to prevent them from being ejected from the vehicle.
