SEAT BELT RETRACTOR WITH FORCE LIMITER
The driver’s/front passenger’s seat belt retractor
has been equipped with a force limiter. The force lim-
iter is a device which operates when a predeter-
mined force is applied, and limits the force.

OPERATION
(1) If a collision energy is transmitted to the seat belt, the
ELR mechanism will operate to lock the seat belt.
(2) Then, if the energy increases to a predetermined value,
the torsion bar will be distorted. As the spool rotates
together with the torsion bar, the seat belt webbing is
pulled out, reducing impact on the occupants.
