ingly.
Head restraints
Correctly adjusted head restraint
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident. Only remove a head
restraint if no one will be sitting on the seat in
question. Reinstall the head restraint before
transporting anyone on that seat. Otherwise,
the passenger will be without protection from
the head restraint.<
Height
Adjust the head restraint so that its center is
approximately at ear level.
Distance
Adjust the distance so that the head restraint is
as close as possible to the back of the head.
