Is it advisable to adjust and adapt the vehicle's head restraints to the physical build of the occupants?
Active and passive safety
Explanation
The **headrest** is a **passive safety element** in vehicles 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 occupants' heads, both in the front and rear seats, to prevent cervical injuries.
- The **cervical vertebrae** are the bones in the upper part of the spine. An impact without adequate protection can cause serious injuries in this area.
- The top of the headrest should be at the same height as the top of the occupant's head.
- The distance between the head and the headrest should be four centimeters or less to maximize protection.
Therefore, it is advisable to adjust and adapt the headrests to the physical build of the occupants to ensure their safety and prevent injuries in the event of an accident.
