**Airbags** are safety devices that inflate in the event of an accident to protect passengers. Their main function is to slow down the sudden movement of the body and prevent people from violently hitting parts of the vehicle. They also protect the face and eyes from broken glass and other elements that become detached during an accident.

However, for the airbag to function safely, it is crucial to always use the **seat belt**. If the seat belt is not fastened, the impact against the airbag can be stronger and more dangerous, as the body is not properly restrained. This can increase the risk of injury instead of reducing it.

Additionally, it is recommended to maintain a distance of at least 25 centimeters between the chest and the steering wheel to prevent the front airbag from hitting the driver when it inflates. It is also important to disconnect the passenger seat airbag if a child seat is going to be placed in that seat.


Therefore, the action of an airbag can be dangerous if the seat belt is not fastened, as the body is not adequately protected and the impact can be more severe.
