Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
front passenger’s SRS frontal airbags in
the steering wheel and instrument panel.
An impact sensor, which senses impact
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.)
For Outback models, 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 impact sensors together
sense an impact force above a predetermined 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 curtain airbags will deploy when
the front sensor and the control unit
determine that the impact results from an
offset frontal collision.
The curtain airbags are designed to
deploy when the driver’s frontal airbag
deploys or the driver’s and passenger’s
frontal airbags deploy in a frontal collision,
and also when the system determines that
the collision is an offset frontal collision.
The curtain airbags are basically designed
not to deploy when the frontal airbags do
not deploy or the system determines that
the collision is other than an offset frontal
collision.
For Outback models, 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 following 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
basically not designed to deploy in a
lesser side impact.
The SRS side airbag and SRS curtain
airbag deployment depend on the level of
force experienced in the passenger compartment 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.
For Outback models, the SRS curtain
airbags are also designed to deploy when
the vehicle is in an extremely inclined
state such as during a rollover. They are
not designed to de ploy in most lesser
inclined state.
