How does the side air bag system work?
The side air bag system consists of
the following:
•An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•A special seat cover designed to
allow air bag deployment.
•The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
•Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated. The front passenger sensing system will
turn off the passenger seat side air bag 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 air bag will be turned off by the front passenger
sensing system. The air bag was designed to inflate between the door
panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
The fact that the air bags 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 air bags 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.
