Which of the mentioned body parts is the headrest on the vehicle seat designed to protect?
aThe cervical spine.
bThe frontal bone
cThe occipital bone.
Why?
A head restraint protects the cervical spine by limiting sudden movement of the head relative to the torso, especially in a rear-end collision. The head restraints shown are adjustable so they can be positioned correctly behind the occupant’s head. Their main purpose is to reduce strain on the neck, rather than shield the frontal or occipital bone from a direct impact.
