Morphology
The noun is compositionally built from 'head' (the body part) + 'restraint' (a device that prevents movement), so the meaning 'a device that restrains the head' is directly derivable. This literal, physical compound follows common noun–noun compounding patterns (and parallels in other languages), so a B1 learner who knows the constituents will readily understand it.
Etymology
The noun head restraint comes from the simple image of a padded support that holds the head and the idea of a restraint that stops sudden movement in a car seat. So, it means a padded support that limits head movement and helps prevent 'whiplash' in a crash.
