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.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it. The
automatic lap-shoulder belt has plenty
of extra length built in, so it will fasten
around almost all people.
But if a safety belt isn't long enough to
fasten, your dealer will order you an
extender. It's free. When you go in to
order it, take the heaviest coat you will
wear, so the extender will be long
enough for you. The extender will be
just for you, and just for the seat in your
vehicle that you choose. Don't let
someone else use it, and use it only for
the seat it is made to fit. To wear it, just
attach it to the regular safety belt.
