If the primary lock is incomplete, ribs interfere and prevent the secondary lock.\n\nSecondary Lock\n\nRibs\n\nPrimary Lock\n\n[Diagram showing three stages: Primary Lock Incomplete (Secondary Lock Prevented), Primary Lock Complete (Secondary Lock Permitted), Twin-Lock Completed]\n\nAB0088\n\nWhen the vehicle is involved in a frontal collision in the hatched area (Fig. 1) and the shock is larger than a predetermined level, the airbag is activated automatically. Safing sensors are designed to go on at a smaller deceleration rate than the front and center airbag sensors. As illustrated in Fig. 2 below, ignition is caused when current flows to the squib, which happens when a safing sensor and a front airbag sensor and/or the center airbag sensor go on simultaneously.\n\nWhen a deceleration force acts on the sensors, it causes the squib to ignite. Gas is then generated, increasing the pressure inside the bag rapidly. The inflated bag breaks open the steering wheel pad. Bag inflation then ends, and the gas is discharged through discharge holes provided behind the bag. The bag becomes deflated as a result.\n\nPower Source\n\nSafing Sensors in Center Airbag Sensor Assembly\n\nSquib\n\nCenter Airbag Sensor\n\nFront Airbag Sensors\n\nFig. 1\nAB0219\n\nFig.
