  • Patent number: 11975677
    Abstract: The airbag device includes an airbag and a gas generator. The gas generator includes a body containing inflation gas and sealed with an unsealable lid, and a discharge portion that includes a housing, an outlet that is formed in the housing and allows outflow of gas to the airbag when the body is unsealed, a piercing pin for unsealing the lid, a spring for moving the pin, a retaining member that retains the spring, and a sliding mechanism that shifts the retaining member to a release position. The sliding mechanism includes a drive source and a connecting member that shifts the retaining member to the release position by a driving force of the drive source. The piercing pin, spring, lid and a portion of the retaining member retaining the spring are housed in the housing. The drive source and connecting member are partitioned from a gas channel inside the housing.
