mETHOds Of REsTRAINT IN AddITION TO THE fRONT sEAT BELTs
Depending on the vehicle, they are
composed of:
– seat belt inertia reel pretension-
ers;
– lap belt pretensioners;
– chest-level load limiters;
– air bags for 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 inertia reel pretensioner
(which engages to correct seat belt
slack);
– the lap seat belt pretensioners to
hold the occupant in his seat;
– the low volume front air bag;
– the large volume front air bag.

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.
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:
– seat belt inertia reel pretensioner 1
which instantly retracts the seat belt;
– piston 2 on the front seats.
– Have the entire restraint
– 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
2
injury, only qualified personnel
from an approved dealer may
work on the pretensioner and air
bag system.
– 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
air bag gas generators.
