78 Seats and Restraints
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle’s safety belts.The manufacturer instructions that
come with the booster seat state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the fit test below:
.
Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
. Buckle the lap-shoulder belt.
Does the shoulder belt rest on
the shoulder? If yes, continue.
If no, try using the rear safety
belt comfort guide, if available.
See “Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt
0 61. If a comfort guide is not
available, or if the shoulder belt
still does not rest on the
shoulder, then return to the
booster seat.
. Does the lap belt fit low and
snug on the hips, touching the
thighs? If yes, continue. If no,
return to the booster seat. .
Can proper safety belt fit be
maintained for the length of the
trip? If yes, continue. If no,
return to the booster seat.
Q: What is the proper way to wear safety belts?
A: An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder
belt can provide. The shoulder
belt should not cross the face or
neck. The lap belt should fit
snugly below the hips, just
touching the top of the thighs.
This applies belt force to the
child's pelvic bones in a crash.
It should never be worn over the
abdomen, which could cause
severe or even fatal internal
injuries in a crash.
Also see “Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt
0 61.
According to accident statistics,
children are safer when properly
restrained in a rear seating position.
