Additional methods of restraint
to the front seatbelt
METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS (1/6)
Depending on the vehicle, they are
composed of:
– seat belt pretensioners;
– chest force limiters;
– airbags
driver and passenger
front.
These systems are designed to act in-
dependently or together when the vehi-
cle is subjected to a frontal impact.
Depending on the severity of the
impact, the system can trigger:
– seat belt locking;
– the seat belt pretensioner (which en-
gages to correct seat belt slack);
– the front airbag;
– the force limiter, in the most severe
impacts.
Pretensioners
The pretensioners hold the seat belt
against the body, holding the occupant
more securely against the seat, thus in-
creasing the seat belt’s efficiency.
With the ignition on, following a signif-
icant 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 (airbag, electronic units,
wiring) and the system compo-
nents must not be reused on any
other vehicle, even if identical.
– To avoid premature triggering
of the system which may cause
injury, only qualified Network per-
sonnel are authorisedto work on
the methods of restraint in addi-
tion to the front seat belt.
– 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 gas generators for
the pretensioners and airbags.
