192 SAFETY
Group 1
Fig. B
Children who weigh between 9 kg and 18 kg may be
carried in a Group 1, forward facing seat like the one in fig.
B. This type of child restraint is for older children who are
too big for a Group 0 or 0+ child restraint.
Group 2
Fig. C
Children who weigh between 15 kg and 25 kg and who are
too big for the Group 1 child restraint may use a Group 2
child restraint system.
As shown in fig. C, the Group 2 child restraint system
positions the child correctly with respect to the seat belt so
that the shoulder belt crosses the child's chest and not the
neck, and the lap belt is snug on the pelvis and not the
abdomen.
Group 3
Fig. D
Children who weigh between 22 kg and 36 kg and who are
tall enough to use the adult shoulder belt may use a Group
3 child restraint. Group 3 child restraints position the lap
belt on the child's pelvis. The child must be tall enough
that the shoulder belt crosses the child's chest and not
their neck.
Fig. D shows an example of a Group 3 child restraint
system correctly positioning the child on the rear seat.
