How Does The Side Airbag System Work? - Ford 2007 Focus Owner's Manual

How does the side airbag system work?

The side airbag system consists of
the following:
• An inflatable nylon bag (airbag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
• A special seat cover designed to
allow airbag deployment.
• The same warning light,
electronic control and diagnostic
unit as used for the front airbags.
• Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side airbags, in combination with
safety belts, can help reduce the risk of severe injuries in the event of a
significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The front passenger sensing system will
turn off the passenger seat side airbag if the seat is empty (unless for
some reason the safety belt is properly buckled). If the front passenger
seat is empty, and the safety belt is not properly buckled, the front
passenger seat side airbag will be turned off by the front passenger
sensing system. The airbag was designed to inflate between the door
panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.
The fact that the airbags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were
not of the type sufficient to cause activation. Side airbags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.
