METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS
(1/3)
– Have the entire restraint
system checked following
an accident.
– No operation whatsoever
is permitted on any part of the
system (air bags, electronic con-
trol units, wiring) and the system
components must not be reused
on any other vehicle, even if iden-
tical.
– 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 pretensioner and
airbag gas generators.
Pretensioner
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 seat
belt.
The pretensioner holds the seat belt
against the body, holding the occupant
more securely against the seat, thus in-
creasing the seat belt’s efficiency.
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.
Depending on the vehicle, they are
composed of:
– seat belt pretensioners;
– chest-level load limiters;
– air bags for the driver and front pas-
senger.
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 to hold the
occupant in the seat, and the force
limiter;
– the front air bag.
