The **safety helmet** is a component of **passive safety**. Passive safety refers to elements that protect users in the event of an accident, reducing damage without requiring active intervention from the user.

- **Function of the helmet**: In the event of an accident, the helmet protects the head from impacts against the ground, other vehicles, or road elements. It also distributes the force of the impact to prevent serious injuries and protects the face and head from burns when sliding on the ground.

- **Importance of the helmet**: Head injuries are the main cause of death in two-wheel vehicle accidents. Wearing a helmet can save lives, as three out of ten people who have an accident on a two-wheel vehicle survive thanks to it.

- **Characteristics of the helmet**: It must be a full-face model that protects the jaw, be well-fitted, have a secure fastening, be of a light color for greater visibility, and have adequate ventilation. Additionally, it must be approved, which guarantees that it has passed quality tests.

For these reasons, the helmet is a crucial element of passive safety, designed to minimize damage in the event of an accident without requiring action from the user.
