The SRS side airbag and curtain shield airbag system is controlled by the airbag sensor assembly. The airbag sensor assembly consists of a safing sensor and airbag sensors. In a severe side impact, the side and curtain shield airbag sensor triggers the side and curtain shield airbag inflators. At this time a chemical reaction in the inflators very quickly fills the airbags with non-toxic gas to help restrain the lateral motion of the occupants. 103
