case of an accident, the headrest
should be adjusted so the middle
of the headrest is at the same
height of the center of gravity of
an occupant's head. Generally,
the center of gravity of most peo-
ple's head is similar with the
height of the top of their eyes.
Also, adjust the headrest as close
to your head as possible. For this
reason, the use of a cushion that
holds the body away from the
seatback is not recommended.

tion against neck injuries when
