A rear - facing infant seat (B) provides restraint with the
seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.
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.
