A booster seat (F-G) is a child restraint designed to
improve the fit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a five-point harness.
A booster seat can also help a child to see out the
window.
Q: How do child restraints work?
A: A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built-in child restraint system is a
permanent part of the motor vehicle. An add-on
child restraint system is a portable one, which
is purchased by the vehicle’s owner.
For many years, add-on child restraints have used
the adult belt system in the vehicle. To help
reduce the chance of injury, the child also has to be
secured within the restraint. The vehicle’s belt
system secures the add-on child restraint in the
vehicle, and the add-on child restraint’s harness
system holds the child in place within the restraint.
Onesystem, the three-point harness, has straps that
comedown over each of the infant’s shoulders and
buckletogether at the crotch. The five-point harness
systemhas two shoulder straps, two hip straps and a
crotchstrap. A shield may take the place of hip
straps.A T-shaped shield has shoulder straps that
areattached to a flat pad which rests low against the
child’sbody. A shelf- or armrest-type shield has
strapsthat are attached to a wide, shelf-like shield
thatswings up or to the side.
