What type of injuries can be reduced by proper use of the headrest?
Active and passive safety
Explanation
The **headrest** is a **passive safety** device in the vehicle that protects the **neck and cervical vertebrae** in the event of a sudden impact. The cervical vertebrae are the bones located at the top of the spine.
For the headrest to fulfill its protective function, it is crucial to position it correctly:
- The top of the headrest should be at the same height as the top of your head.
- The distance between your head and the headrest should be four centimeters or less.
Proper use of the headrest can reduce the risk of **cervical injuries** in the event of an accident, as it prevents sudden neck movements that could cause harm.
