aint syst em in an accident
em in an accident How
there straint system works depends on the
se verity of the impact de tected and the apparent
type of accident:
R Frontal impact
R Rear impact
R Side impact
R Rollover
The activation thre sholds forth e components of
th ere straint system are de term ined based on the
ev aluation of the sensor values measured at vari-
ous points in theve hicle. This process is pre-e mp-
tive in nature. The triggering/deployment of the
components of there straint system must take
place in good time at the start of the collision.
Fa ctors which can only be seen and measured
aTer a collision has occur red cannot play a deci- sive
role in airbag deployment. Nor do they pro-
vide an indication of airbag deployment.
The vehicle may be deformed signi/cantly without
an airbag being deplo yed. This is the case if only
parts which are relatively easily deformed are
a.ec tedand thera te of vehicle deceleration is
not high. Con versely, an airbag may be depl oyed
ev en though theve hicle su.ers only minor defor-
mation. If very rigid vehicle parts such as longitu-
dinal membe rsare hit, this may result in su1-
ciently high le vels of vehicle deceleration.
Depending on the de tected deployment situation,
th e components of there straint system can be
acti vated or deplo yed independently of each
ot her:
R Seat belt tensioner: frontal impact, rear
impact, side impact, rollo ver
R Driver's airbag, front passenger airbag: frontal
impact
R Knee airbag: frontal impact
R Side airbag: side impact
