The **airbag** is a passive safety device designed to protect vehicle occupants in the event of an accident. Its main functions are to slow down the abrupt movement of the body, prevent violent collisions with parts of the vehicle, and protect the face and eyes from broken glass and other detached elements.

However, for the airbag to function effectively and safely, it is **essential** that vehicle occupants use the **seat belt**. The seat belt keeps people in place, preventing them from moving too far forward during an impact. This is crucial because the airbag inflates with great force and speed. If a person is not wearing the seat belt, they may be too close to the airbag when it deploys, which can cause **serious injuries** due to the direct impact of the airbag.


Therefore, the use of the seat belt is fundamental to reduce the risk of injuries caused by the airbag and to maximize the protection that both devices offer together.
