A side impact protection airbag system includes an inflator, a retainer and an airbag. An interior space of the airbag is divided into a pelvis portion protecting chamber and a chest portion protecting chamber by a dividing part. A gas ejecting part of the inflator and an opening in the retainer are provided between a fixing end portion of the airbag and an end portion (a connecting portion) of the dividing part which lies a side facing the fixing end portion. A circumferential portion on a wall part which is separate from the opening is made to constitute an interruption wall which interrupts the passage of an inflation gas to the dividing part side, and the interruption wall is provided between the gas ejecting part and the connecting portion.
