Seats & Safety Belts
Q: What if
a
child is wearing a lapshoulder belt, but the child
i s
so
small that the shoulder belt is very close to the child's face or neck?
A: Move the child toward the center
of
the vehicle, but be sure that the
shoulder belt still
is on the child's shoulder,
so that in a crash the child's
upper body would have the restraint that belts provide. If the child is so small
that the shoulder belt still is very close to the child's face or neck, you might
want to place the child in seat that has a lap belt, i f your vehicle has one.

I
Never
do this.
A
Here a child is sitting in a seat that has a lapshoulder 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.
