Airbag system components
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly.
The airbag sensor assembly consists of a safing sensor and an air-
bag sensor.
In certain types of severe frontal or side impacts, the SRS airbag
system triggers the airbag inflators. A chemical reaction in the
inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants. Knee airbags
