A forward - facing child seat (C - E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T
- shaped or shelf - like shields.
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.
