Is it advisable to have the head restraints properly adjusted on all the seats in a car?
Active and passive safety
Explanation
The **headrest** is a **passive safety element** in vehicles. Its main function is to protect the neck and cervical spine of the occupants in the event of a sudden impact, such as an accident. To fulfill its function correctly, it is crucial that it is properly adjusted to the height of each passenger's head, both in the front and rear seats.
- 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 not be greater than four centimeters.
A well-adjusted headrest can prevent serious cervical injuries, such as whiplash, which is common in rear-end collisions. Therefore, it is advisable to properly adjust the headrests in all the seats of a car to ensure the safety of all passengers.
