Methods of restraint in addition
to the front seat belts
Depending on the vehicle, they may
comprise:
– seat belt inertia reel
pretensioners;
– lap seat belt pretensioners;
– chest force limiters;
– airbags driver and passenger
front.
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 cause:
– blocking of the seat belt;
– the seat belt inertia reel pretensioner
which is triggered to correct seat belt
slack;
– the lap seat belt pretensioner to hold
the occupant in their seat;
– the front airbag.
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.
In the event of a severe frontal impact
and if the ignition is switched on, the
system may engage the following
depending on the force of the impact:
– the seat belt inertia reel pretensioner
1
which instantly retracts the seat belt;
– the lap seat belt inertia reel
pretensioner
2
on the front seats.
– Have the entire
restraint system checked
following an accident.
– No operation whatsoever 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 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.
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.
