Description & Operation: Notes
The Supplemental Restraint System (SRS) is designed to provide increased accident protection for driver and passenger by deploying air bags in a front-end collision. The air bags, stored in center of steering wheel and in instrument panel above glove box, deploy in about 40 milliseconds after impact sensors close. SRS is designed to be used with 3-point safety belts.
During a front-end collision, front impact sensor internal balls are thrown forward. The balls complete an electrical circuit and ignite inflator to deploy air bag. At least 2 sensors, one safing sensor and one front impact sensor, must activate simultaneously to inflate air bag.
SRS includes following components: diagnostic monitor, driver-side air bag module, passenger-side air bag module, SRS readiness light (AIR BAG warning light), front impact sensors and safing sensor, ignitor assemblies (in air bag modules), clockspring) and associated wiring harnesses. See Fig 1 .
