If th ere stra int sy stem is malfunctioning,

ge red at all in theev ent of an accident. This
may af fect the Emer gency Tensioning Device

Fu nction of there stra int sy stem in an acci‐
dent
How there stra int sy stem works is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
RFr ontal impact
RRe ar impact
RSide impact
RRo llover
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of
th e components of there stra int sy stem should ta
ke place in good time at thest art of the colli‐

sive role in air bag deployment, nor do they pro‐
vide an indication of air bag deployment.
The vehicle may be deformed significantly with‐
out an air bag being deplo yed. This is the case if
only parts which are relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an air bag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, forex am‐
