Methods of restraint in addition to the front seat belts
METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS (1/5)
Depending on the vehicle, they are
composed of:
– seat belt pretensioners;
– chest-level load 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 seat belt pretensioner
to hold the occupant in the seat, and
the force limiter;
– the front airbag .
– Have the entire restraint
system checked following
an accident.
– No operation whatso-
ever is permitted on any part
of the system (pretensioners,
airbags, computers, wiring) and
the system components must not
be reused on any other vehicle,
even if identical.
– Only qualified personnel from our
Network may work on the airbags;
otherwise the system may trigger
accidentally and cause injury.
– 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
airbags gas generators.
The passenger airbag protects 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 in-
creasing the seat belt’s efficiency.
With the ignition switched on, if the
vehicle is subject to a significant fron-
tal impact the system may, depending
on the severity of the impact, trigger a
piston which instantly retracts the belt.
Load limiter
Above a certain level of impact force,
this mechanism is used to limit the force
of the belt against the body so that it is
at an acceptable level.
