Patent ID: 11608024

Abstract:
An airbag device includes an actuator of a configuration that causes a string-form coupling member extending from an airbag to be coupled, and controls an inflation aspect of the airbag by causing a state of coupling with the coupling member to be maintained or terminated. The actuator includes a gas generator that can eject a combustion gas and a holder portion that can hold the coupling member. The holder portion includes a holding wall portion, which can hold the wound coupling member on an outer peripheral face side, and a top wall portion that closes a leading end side of the holding wall portion, and a contact region in which the combustion gas can be brought into contact with the coupling member is disposed in a region of the holding wall portion. The actuator causes the coupling member to be severed by causing the combustion gas to come into contact with the coupling member in the contact region, whereby a state of the coupling member being held in the holder portion can be terminated.
