Function
If the airbag sensor registers an accident, one or more airbag sensors first measure the severity of the accident. An ignition current is sent immediately from the airbag triggering device into a pyrotechnical container, which triggers an ignition. The pyrotechnical material burns, the generated gas fills the airbag.
Inflation of the seat cushion improves the pelvis support and the vehicle occupant is lifted up in the event of a frontal impact by the cushionbag thereby preventing them from slipping under the seat belt.
The operational readiness of the airbag is constantly monitored by the diagnostic system. In the event of a current interruption, the ignition energy is maintained by a capacitor.
The Supplemental Restraint System (SRS) control unit actuates the rear passenger compartment cushionbag squib (2) directly.
