Top Tether Anchor
A top tether (A, C) anchors the top of the child restraint
to the vehicle. A top tether anchor is built into the
vehicle. The top tether attachment (B) on the child
restraint connects to the top tether anchor in the vehicle
in order to reduce the forward movement and rotation
of the child restraint during driving or in a crash.
Your child restraint may have a single tether (A) or a
dual tether (C). Either will have a single attachment (B)
to secure the top tether to the anchor.
Some top tether-equipped child restraints are designed
for use with or without the top tether being attached.
Others require the top tether always to be attached.
In Canada, the law requires that forward-facing
child restraints have a top tether, and that the tether
be attached. In the United States, some child restraints
also have a top tether. Be sure to read and follow
the instructions for your child restraint.
If the child restraint does not have a top tether, one
can be obtained, in kit form, for many child restraints.
Ask the child restraint manufacturer whether or not
a kit is available.
