METHODS OF RESTRAINT IN ADDITION TO REAR SEAT BELTS
The rear outer seat belts are fitted
with:
■ pretensioners integrated into the
inertia reel,
■ force limiters.
These two devices are designed to
act independently or together in the
event of frontal impacts.
There are two scenarios, depending
on the force of the impact:
- protection is provided by the belt
only;
- the pretensioner is triggered to
recover seat belt play.

seconds after the ignition has been

rear impact, a piston instantly
retracts the seat belt buckle or the
inertia reel. The winding up of the
belt pulls the seat belt against the
body and thereby increases its
efficiency.
Force limiter
In the event of a front impact above
a certain level of severity, this
mechanism is used to limit the force
of the belt against the body so that it
is kept at an acceptable level.
