To improve the fit of both the lap and shoulder belt on children who
have outgrown child safety seats, Ford Motor Company recommends use
of a belt-positioning booster.
Booster seats position a child so that safety belts fit better. They lift the
child up so that the lap belt rests low across the hips and the knees
bend comfortably. Booster seats may also make the shoulder belt fit
better and more comfortably. Try to keep the belt near the middle of the
shoulder.
When children should use booster seats
Children need to use booster seats from the time they outgrow the
toddler seat until they are big enough for the vehicle seat and
lap/shoulder belt to fit properly. Generally this is when they weigh about
80 lb. (36 kg) (about 8 to 12 years old).
Booster seats should be used until you can answer YES to ALL of these
questions:
•
Can the child sit all the way back
against the vehicle seat back with
knees bent comfortably at the
edge of the seat without
slouching?
•
Does the lap belt rest low across the hips?
•
Is the shoulder belt centered on the shoulder and chest?
•
Can the child stay seated like this for the whole trip?
