METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS
Depending on the vehicle, they will
consist of :
– seat belt inertia reel
2
pretensioners ;
– chest-level load limiters ;
– air bags for driver and front
passenger.
These systems are designed to act
independently or together when the
vehicle is subjected to a frontal impact.
Depending on the severity of the
impact, the system can trigger :
– seat belt locking ;
– the seat belt inertia reel pretensioner
(which engages to correct seat belt
slack) ;
– airbags.

Pretensioners
The pretensioners (in driver side) hold
the seat belt against the body, holding
the occupant more securely against
the seat, thus increasing the seat belt's
efficiency.
With the ignition on, following a
significant frontal impact and
depending on the severity of the
impact, the system may trigger the
seat belt inertia reel pretensioner 1 ,
which instantly retracts the seat belt.
– Have the entire
restraint system checked
following an accident.
– No operation whatsoever is
permitted on any part of the
system (pretensioners, air bags,
computers, wiring) and the
system components must not be
reused on any other vehicle, even
if identical.
– To avoid incorrect triggering of
the system which may cause
injury, only qualified personnel
from an approved Dealer may
work on the pretensioner and air
bag system.
– The electric trigger system may
only be tested by a specially
trained technician using special
equipment.
– When the vehicle is scrapped,
contact an approved Dealer for
disposal of the pretensioner and
air bag gas generators.
Load limiter (in driver side)
Above a certain severity of impact, this
mechanism is used to limit the force of
