Upon detection of a vehicle emergency, the inflator(s) supply expansion gas to the airbag cushion, which inflates upward to raise the seat surface and restrain the occupant's waist/pelvis region. A key feature is the controlled timing of gas generation from one or more gas-generating parts, adjusted based on vehicle sensor input, enabling staged or optimized inflation sequences.
