CAUTION:
{
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child's
hip bones are still so small that the vehicle's
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child's abdomen. In a crash,
the belt would apply force on a body area that
is unprotected by any bony structure. This
alone could cause serious or fatal injuries.
Young children should always be secured in
appropriate child restraints.
Child Restraint Systems
The harness system holds the infant in place and, in a
crash, acts to keep the infant positioned in the restraint.
A rear-facing infant
seat (A) provides restraint
with the seating surface
against the back of
the infant.
A forward-facing child
seat (B) provides restraint
for the child's body
with the harness.
