FORD 2007 F-150 v.2 - Manual (Page 191)

If the safety seat is not anchored properly, the risk of a child
being injured in a collision greatly increases.
Rear seat tether strap attachment
There are three loops of webbing
just above the back of the rear seat
(along the bottom edge of the rear
window) in the SuperCab and
SuperCrew. These loops are to be
used as both routing loops and
anchor loops for up to three child
safety seat tether straps. For
example, the center loop can be
used as a routing loop for a child
safety seat in the center rear seat
and as an anchoring loop for child seats installed in the outboard rear
seats.
Many tether straps cannot be tightened if the tether strap is hooked to
the loop directly behind the child seat. To provide a tight tether strap:
1. Route the tether strap under the
head restraint and through the loop
directly behind the child seat.
