The Importance Of Shoulder Belts - Ford 2008 F-250 Owner's Manual

• Those with a high back.
If, with a backless booster seat,
you cannot find a seating position
that adequately supports your
child's head, a high back booster
seat would be a better choice.
Either type can be used at any seating position equipped with
lap/shoulder belts if your child is over 40 lb. (18 kg).
Children and booster seats vary widely in size and shape. Choose a
booster that keeps the lap belt low and snug across the hips, never up
across the stomach, and lets you adjust the shoulder belt to cross the
chest and rest snugly near the center of the shoulder. The drawings
below compare the ideal fit (center) to a shoulder belt uncomfortably
close to the neck and a shoulder belt that could slip off the shoulder.
If the booster seat slides on the vehicle seat, placing a rubberized mesh
sold as shelf or carpet liner under the booster seat may improve this
condition.

The importance of shoulder belts

Using a booster without a shoulder belt increases the risk of a child's
head hitting a hard surface in a collision. For this reason, you should
never use a booster seat with a lap belt only. It is best to use a booster
seat with lap/shoulder belts in the back seat- the safest place for children
to ride.
Move a child to a different seating location if the shoulder belt
does not stay positioned on the shoulder during use.
