Vehicle occupant restraining device

An occupant restraining device that restrains an occupant sitting on a seat of a vehicle, the occupant restraining device comprising:

• an airbag stowable in a seatback of the seat for expansion and deployment to a side of an occupant seated in the seat;
• an angle detecting means that detects a reclining angle of the seatback;
• internal pressure control means for controlling an internal pressure of the airbag during expansion and deployment according to the reclining angle;
• and
• first and second inflators for supplying gas to the airbag,
• wherein the internal pressure control means is operative to decrease the internal pressure of the airbag if the reclining angle of the seatback is more than a prescribed angle during expansion and deployment of the airbag, and
• wherein the internal pressure control means controls the internal pressure of the airbag by delaying gas discharge timing of the second inflator from that of the first inflator.
