The **airbag** is a passive safety device in vehicles that inflates in the event of an accident. Its main function is to **protect passengers** by preventing them from violently colliding with parts of the car, such as the steering wheel or dashboard. This is achieved by slowing down the abrupt movement of the body during an impact.

Additionally, the airbag helps to **protect the face and eyes** of the occupants from possible broken glass or other elements that may become detached during the accident. Therefore, its purpose is clear: **to prevent injuries** by stopping passengers from hitting the interior of the vehicle.

For safe use of the airbag, it is important to maintain an adequate distance from the steering wheel and always use the seatbelt, which minimizes the impact against the airbag when it inflates.
