following an accident.
Depending on the vehicle, they may
comprise:
– No operation whatsoever is per-
mitted on any part of the system
(pretensioners, airbags, comput-
ers, wiring) and the system com-
ponents must not be reused on
any other vehicle, even if identi-
cal.
– 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

equipment.
– When the vehicle is scrapped,

– chest force limiters;
– airbags driver and passenger
front.
These systems are designed to act in-
dependently or together when the ve-

Depending on the severity of the im-
pact, the system can cause:
– blocking of the seat belt;
– the seat belt pretensioner to hold the

The pretensioners hold the seat belt
against the body, holding the occupant
more securely against the seat, thus
increasing the seat belt's efficiency.

the severity of the impact, the system
may trigger the seat belt inertia reel
pretensioner 1 which instantly retracts
the seat belt.
