**Passive safety systems** are elements designed to **reduce damage** to passengers and other users in the event of an accident. Examples of these systems include the **seat belt**, the **airbag**, and the **headrest**. They operate automatically, and their correct use is crucial to ensure their effectiveness.

- **Seat belt**: It must be properly adjusted to prevent the body from moving abruptly during an accident.
- **Airbag**: Its function is to slow down the abrupt movement of the body, prevent violent impacts against parts of the vehicle, and protect the face and eyes from broken glass and other elements.


**Misuse** of these systems, such as not fastening the seat belt correctly or sitting too close to the steering wheel where the airbag is located, can **increase the risk of injury** instead of preventing it. Therefore, it is essential to use them properly to maximize their protective capacity.
