ADDITIONAL SAFETY DEVICES

Methods of restraint in addition
to the rear seat belts
Depending on the vehicle, they may
comprise:
– side seat belt inertia reel preten-
sioners;
– chest force limiters.
These systems are designed to act in-
dependently or together when the ve-
hicle is subjected to a frontal impact.
Depending on the severity of the im-
pact, the system can cause:
– blocking of the seat belt;
– the seat belt inertia reel pretensioner
(which engages to correct seat belt
slack).
Load limiter
Above a certain severity of impact, this
mechanism is used to limit the force of
the belt against the body so that it is at
an acceptable level.
Side seat belt pretensioners
The pretensioners 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 signifi-
cant 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 re-
straint system checked
following an accident.
– No operation whatsoever is per-
mitted on any part of the system
(pretensioners, airbags, comput-
ers, wiring) and the system com-
ponents must not be reused on
any other vehicle, even if identi-
cal.
– Only qualified personnel from
our Network may work on the
airbags; otherwise the system
may trigger accidentally and
cause injury.
– The electrical 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
airbags gas generators.
