The
rate ofvehicle deceleration oraccelera-
tion andthedirection ofthe force areessen-
tially determin edby:
R the distribution offorces during thecollision
R the collision angle
R the deformation characteristics ofthe vehi-
cle
R the charact eristics ofthe object withwhich
the vehicle hascollided
Fact orswhich canonly beseen andmeasured
after acollision hasoccurred donot play a
decisive roleinthe deployment ofan air bag.
Nor dothey provide anindication ofair bag
deployment.
The vehicle canbedeformed considerably,
without anair bag being deployed. Thisisthe
case ifonly parts which arerelatively easily
deformed areaffect edand therate ofdeceler-
ation isnot high. Conversely, airbags maybe
deployed eventhough thevehicle suffersonly
minor deformation .This isthe case if,for
example, veryrigid vehicle partssuchaslongi-
tudinal bodymembers arehit,and sufficient
deceleration occursasaresult.
If the restr aintsystem controlunit detect sa
side impact orifthe vehicle rollsover, the
applicable componentsofthe restr aintsystem
are deployed independent lyof each other
depending onthe apparent typeofaccident .
R Side impact airbags onthe side where the
impact takesplace, independent lyof the
Emergen cyTensionin gDevice andtheuse
of the seat beltonthe driver's seatand
outer seats inthe second row
The side impact airbag onthe front
passenger sidedeploys underthefollowing
condit ions:
- the OCS system detectsthat thefront
passenger seatisoccupied or
- the seat beltbuckle tongue isengaged in
the belt buckle ofthe front passenger
seat
R Window curtainairbag onthe side of
impact, independent lyof the use ofthe seat
belt andindependent lyof whether thefront -
passenger seatisoccupied
R Emergen cyTensionin gDevices, ifthe sys-
tem determin esthat deployment canoffer
additional protectioninthis situation
R Window curtainairbags onthe driver's and
front -passenger sideincert ainsituations
when thevehicle rollsover, ifthe system determin
esthat deployment canoffer addi-
tional protec tiontothat provided bythe
seat belt
i Not
allair bags aredeployed inan acci-
dent. Thevarious airbags work independ-
ently ofeach other .
How theairbag works isdetermin edbythe
severity ofthe accident detected,especially
the vehicle deceleration oracceleration and
the apparent typeofaccident :
