bosom. In the case of an accident of
the front bumping, excessive tilting
of a seat might increase injury risk.

can wear seat belt properly.

The children must sit on back seat and
wear seat belt properly for protection. In
accordance with accident statistics, it is
safer for the children to seat in a back
seat under proper protection than in a
front seat.
