**Seat belts** and **airbags** are considered **passive safety** systems. These elements are designed to **minimize injuries** to passengers in the event of an accident.

- **Airbags**: These are devices that automatically inflate during 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 objects that may become detached.

- **Seat belts**: They work similarly to airbags, as they help keep passengers in place, reducing the risk of injury by preventing them from moving abruptly during an impact.

These systems are automatic and do not require driver intervention to activate, classifying them as **passive safety** elements. Their goal is to **reduce injuries** in the event of an accident, rather than preventing the accident itself.
