Section 17: Glossary
3-Point Seat Belt (Lap/Shoulder Belt): A seat belt with both
a lap and a shoulder portion, having three contact points (one
shoulder, two hips).
2-Point Seat Belt (Lap Belt Only): A seat belt system with two
contact points, (two hip points).
Airbag: A passive (idle) restraint system that automatically
deploys during a crash to act as a cushion for the occupant.
It creates a broad surface on which to spread the forces of
the crash, to reduce head and chest injury. It is considered
"supplementary" to the lap/shoulder belts because it enhances
the protection the belt system offers in frontal crashes. Also
known as SRS - Supplemental Restraint System; SIR -
Supplemental Inflatable Restraint; IC - Inflatable Curtain;
SIAB - Side Impact AirBag.
Belt-Positioning Booster: A platform that raises the child
(provides a taller sitting height) so adult lap and shoulder belts
fit better; some have high backs as well. Never use with a lap
belt only across the child. Also called a "Booster Seat."
Belt Routings: The manufacturer's required place where
the safety belt passes around or through the child restraint.
Indicated in red on this child restraint.
Child Restraint System: Common term for a specially
designed device that secures a child in a motor vehicle, meets
federal safety standards and increases child safety in a crash.
Also called a "Car Seat."
