Seat Positions

Rear-Facing
When properly installed in the rear-
facing position, the back angle of the
child seat should be at least 30˚ for
children and up to 45˚ from vertical for
infants unable to maintain head and
neck control (not to exceed 45˚) when
the car is parked on a level surface.
Use the line as a guide to achieve the proper recline angle
for rear-facing installations. The line will be parallel to the
ground when the child seat angle is at the center of the
acceptable angle range (37.5˚). If necessary, the proper
recline angle can be achieved by placing a rolled towel or
pool noodle in the vehicle seat bight.
Forward-Facing
In forward-facing
installations, it is
important that the base
of the child seat rests
completely flat on the
vehicle seat. As seen
in the illustration, it is
permissible to allow up to
20% or 7.6 cm (3 in.) of
the base to hang over the
edge of the vehicle seat.
Some vehicle seats do
not allow enough of the child seat base to contact the vehicle
seat. If this is the case, adjust the recline angle to a more
upright position. Not doing so could cause the child seat to
not perform as intended.
