Abstract

Abstract A side-impact airbag device capable of being located in a narrow and restricted position and promptly and sufficiently inflating an airbag to a predetermined range even if a part such as an arm rest or the like is provided. An airbag body is disposed so as to be spread over a side wall such as a side door or the like. Predetermined portions of the airbag body, which correspond to the part such as the arm rest or the like attached to the side door, are bonded to one another so that the predetermined portions are prevented from inflating due to the introduction of gas therein. An inflator is used to inflate the entirety of the airbag body on the average.
