OCCUPANT RESTRAINT SYSTEM " 1 Front passenger occupant classification system (ECU and sensors) 2 Side and curtain shield airbag sensor assemblies 3 Side airbag modules (airbag and inflator) 4 Curtain shield airbag modules (airbag and inflater) 5 Curtain shield airbag sensor assemblies 6 SRS warning light 7 Front passenger's seat belt buckle switch 8 "AIRBAG OFF" and "AIRBAG ON" indicator lights 9 Airbag sensor assembly The SRS side airbag and curtain shield airbag system consists mainly of the above components, and their locations are shown in the illustration. 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 sensor. In a severe side impact, the side and curtain shield airbag sensor and/or the curtain shield airbag sensor trigger(s) the side airbag inflators and/or the curtain shield airbag inflators. At this time a chemical reaction in the inflators quickly fills the airbags with non−toxic gas to help restrain the lateral motion of the occupants. 127
