Is it necessary to adjust the headrest?
Active and passive safety
It is necessary to adjust the headrest in both the front and rear seats to protect the neck and cervical spine in the event of an impact, ensuring it is at the correct height for each passenger's head.
Explanation
The **headrest** is a **passive safety** device that protects the neck and cervical spine in the event of a sudden impact. It is crucial to adjust the headrest to the height of the passengers' heads, both in the front and rear seats. This is because the top of the headrest should be at the same height as the top of the head to provide adequate protection.
Additionally, it is important that the distance between the head and the headrest is four centimeters or less to maximize its effectiveness. Therefore, it is necessary to adjust the headrest in all the vehicle's seats to ensure the safety of all occupants.
