METhOds Of REsTRAINT IN AddITION TO ThE fRONT sEAT BELTs (1/4)
Depending on the vehicle, they are
composed of:
– seat belt inertia reel pretension -
ers 1;
– lap belt pretensioner 2;
– air bags for driver and front pas -
senger 3.
These systems are designed to act in-
dependently or together when the vehi-
cle is subjected to a frontal impact.
The following systems will be triggered
according to the level of impact force:
– seat belt locking;
– the seat belt inertia reel pretensioner
(which engages to correct seat belt
slack);
– the lap seat belt pretensioners to
hold the occupant in his seat;
– the front air bag.
pretensioners
The pretensioners flatten the belt
against the body, holding the occupant
against the seat, thus improving the ef-
ficiency of the belt.
In the event of a severe frontal impact
and if the ignition is switched on, the
system may engage the following de -
pending on the force of the impact:
– the seat belt inertia reel preten -
sioner 1 which instantly retracts the
seat belt;
– the lap belt pretensioner 2 which in-
stantly retracts the lap belt.
– Have the entire restraint
system checked following
an accident.
– No operation whatso -
ever is permitted on any part of
the system (pretensioners, air
bags, computers, wiring) and the
system components must not
be reused on any other vehicle,
even if identical.
– To avoid incorrect triggering of
the system which may cause
injury, only qualified personnel
from an approved dealer may
work on the pretensioner and air
bag system.
– The ignition module electrical
specifications 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
air bag gas generators.
