Abstract:
1. An airbag device comprising: an airbag which has a gas supply port and an inner peripheral portion; an inflator which supplies gas to the inside of said airbag through said gas supply port; a gas discharge state switching member which is attached to an opening portion provided in said airbag, and is configured to be changed over from a gas discharge state where the gas in said airbag is dischargeable to a gas non-discharge state where discharge of the gas in said airbag is suppressed; a connecting member comprising one end portion which is connected to said gas discharge state switching member, and the other end portion which is connected to a portion of said inner peripheral portion of said airbag such that when said inflator initially supplies gas to the inside of said airbag, said gas discharge state switching member is on the outside of the opening portion of the airbag and in a gas discharge state where gas in said airbag is dischargeable through the gas discharge state switching member, and as the inflator continues to supply gas to the inside of the airbag causing expansion of the airbag, the connecting member is configured to pull the gas discharge state switching member into the inside of the airbag thereby changing the gas discharge state switching member over to a gas non-discharge state where discharge of the gas from said airbag through said gas discharge state switching member is suppressed; and a vent hole which is formed in said airbag and through which the gas is discharged at a gas discharge speed slower than a gas discharge speed of said gas discharge state switching member in said gas discharge state, wherein:
