ADDITIONAL SAFETY DEVICES
Methods of restraint in addition
to the front seat belts
Depending on the vehicle, they may
comprise:
– seat belt pretensioners;
– chest force limiters;
– Airbags driver and passenger
front.
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 pretensioner to hold the
occupant in the seat, in addition to the
force limiter;
– the front airbag.
The passenger airbag pro­
tects the front passenger(s)
(depending on whether
there is a conventional seat or a
bench seat in the front).
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 switched on, if the ve­
hicle is subject to a significant frontal
impact the system may, depending on
the severity of the impact, trigger a pis­
ton which instantly retracts the belt.
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.
– 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.
