How does the side airbag system work?
The design and development of the side airbag system included
recommended testing procedures that were developed by a group of
automotive safety experts known as the Side Airbag Technical Working
Group. These recommended testing procedures help reduce the risk of
injuries related to the deployment of side airbags.
The side airbag system consists of
the following:
• An inflatable bag (airbag) with an
inflator 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.
• Crash sensors located on the
front doors and C pillars (one
sensor on each pillar on each side
of the vehicle).
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 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.
