Top Tether Anchor
A top tether (3,4) is used to secure
the top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment hook (2) 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.
The child restraint may have a
single tether (3) or a dual tether (4).
Either will have a single attachment
hook (2) to secure the top tether to
the anchor.
Some child restraints that have a
top tether 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. Be sure to read and follow
the instructions for the child
restraint.
