Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
force, is located in each of the following
locations.
. In the left and right front doors
. In the left and right center pillars
. In the left and right rear wheel houses
. In the airbag control module
. In the left and right front fenders (only
SRS curtain airbags are designed to
deploy when the front sub sensors sense
a severe impact.)
A rollover sensor is also located inside the
airbag control module.
If the impact sensor that is located in the
airbag control module and one of the
center pillar impact sensors or front door
impact sensors together sense an impact
force above a predetermined level in a
side collision, the control module causes
both the SRS side airbag and curtain
airbag on the impacted side to inflate
regardless of whether the rear wheel
house impact sensor on the same side
senses an impact.
If the impact sensor that is located in the
airbag control module and one of the rear
wheel house impac t senso rs to gethe r
sense an impact force above a predeter-
mined level in a side collision, the control
module causes only the SRS curtain
airbag on the impacted side to inflate.
Even if a frontal collision occurs, both right
and left SRS curtain airbags will deploy
when the front sensor and the control unit
determine that the impact results from an
offset frontal collision.
The SRS curtain airbags are designed to
deploy when the driver’sSRSfrontal
airbag deploys or the driver’s and pas-
senger ’s SRS frontal airbags deploy in a
frontal collision, and also when the system
determines that the collision is an offset
frontal collision. The SRS curtain airbags
are basically designed not to deploy in a
frontal collision when the SRS frontal
airbags do not deploy or the system
determines that the collision is other than
an offset frontal collision.
If the rollover sensor detects rollover of the
vehicle, the control module inflates the
SRS curtain airbags. At this time, the
driver’s and front passenger’s seatbelt
pretensioners also operate at the same
time.
After the deployment, the SRS side airbag
immediately starts to deflate. The time
required from detection of an impact to
deflation of an SRS side airbag after
deployment is shorter than the blink of
an eye.
The SRS curtain airbag remains inflated
for a while fo llowing deployment then
slowly deflates.
The SRS side airbag and SRS curtain
airbag deploy even when no one occupies
the seat on the side on which an impact is
applied.
The SRS side airbag and SRS curtain
airbag are designed to deploy in the event
of an accident involving a moderate to
severe side impact collision. They are not
designed to deploy in most lesser side
impact. Also, they are not designed to
deploy in most rear impacts because SRS
side airbag and SRS curtain airbag
deployment would not help the occupant
in those situations.
The SRS side airbag and SRS curtain
airbag deployment depend on the level of
force experienced in the passenger com-
partment during a side impact collision.
That level differs from one type of collision
to another, and it may have no bearing on
the visible damage done to the vehicle
itself.
The SRS curtain airbags are also de-
signed to deploy when the vehicle is in an
extremely inclined state such as during a
rollover. They are not designed to deploy
in most lesser inclined state.
