The seat belts are locked during
heavy acceleration or deceleration of
the vehicle holding the occupants in
the sitting position. Thereby the risk of injury is considerably reduced.

not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child

Make sure that the belts are not
damaged by shoes or sharp-edged
objects or trapped. Prevent dirt from
getting into the belt retractors.
