Seat Belt EntanglementThe majority of seat belts have a locking mechanism that is activated when the seat belt is pulled all the way out from the retractor. This feature is designed for child seat installation. In instances when the locking feature activates, the child may not be able to free him or herself.
This can happen if you do not properly restrain your child, for example, if you let the child lie
down or sleep on the vehicle seat, instead of being properly restrained. Older children who
are no longer in a child restraint system, can become entangled by pulling a seat belt all the
way out of the retractor, or by playing with an unused seat belt.
