Never do this.
Here a child is sitting in
a
seat that has
a
lap-shoulder belt, but the shoulder part
is
behind
the child.
If
the child wears the belt in this
way,
in
a
crash the child might slide under the belt. The
belt's force would then be applied right on the
child's abdomen. That could cause serious
or
fatal injuries.
Wherever
the
child sits, the lap portion
of
the belt
should be
worn
low
and
snug
on
the hips, just touching
the child's thighs. This applies belt force to the child's
pelvic bones
in
a
crash.
