Vehicle deceleration or acceleration and
the direction of the force are essentially
determined by:
the distribution of the force during the
impact
the collision angle
the deformation characteristics of the
vehicle
the composition of the object involved
in the collision, for example the other
vehicle
Factors that cannot be seen or measured
until after the collision are not used to determine whether the airbag should be triggered and are not decisive for this.
The vehicle may be substantially deformed
without an airbag being triggered, for example if only relatively easily-deformable vehicle
parts such as the hood or fenders are affected by the collision and the required deceleration threshold is not reached. On the other
hand, airbags may be triggered even though
the vehicle only displays minor deformation,
Emergency tensioning retractors, belt
force limiters
If the vehicle is equipped with a driver’s airbag, the driver’s and the co-driver’s seat
belts are equipped with emergency tensioning retractors.
A belt force limiter additionally installed in
the seat belt reduces the load exerted by
the seat belt on the occupant when it is
triggered.
Emergency tensioning retractors tension
the seat belts in an accident, pulling them
close against the body.
When the ignition is on, the emergency
tensioning retractor is activated:
only if the restraint systems are opera-
tional (the 1-warning lamp comes
on for approximately 4 seconds after
the ignition is switched on.)
( page 28).
in the event of a head-on or rear-end
collision, if there is a high rate of vehicle acceleration or deceleration in the
initial stages of a collision
in the event of a side impact, if the ve-
hicle suddenly decelerates or accelerates in a lateral direction at the initial
stage of the impact and the vehicle is
equipped with thorax/sidebags and/
or windowbags.
If the emergency tensioning retractors are
triggered, you will hear a bang that is generally harmless to your hearing. A small
amount of powder may also be released.
The 1 warning lamp lights up.

Emergency tensioning retractors do
not correct:
incorrect sitting positions
incorrectly worn seat belts
Emergency tensioning retractors do
not pull occupants back towards the
backrest.
