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 depl oyed. This is the case if only
parts which are relatively easily deformed are
