  • Publication number: 20120068444
    Abstract: The present invention provides an airbag device that is capable of restraining a rectification cloth that switches a vent hole to an opened or closed state so as not to be twisted, and that is capable of switching the vent hole from an opened state to a closed state, and further, switching to the opened state. At an initial stage at which an airbag main body inflates and expands, the vent hole 8 is arranged between the leg portions 5, and when the airbag main body is in a predetermined internal pressure state, the vent hole is closed by means of the band-shaped portion 4. If an occupant or the like comes into contact with the airbag main body, a tense state of each of the leg portions is released, the rectification cloth is established in a slackened state, and the vent hole 8 is established in an opened state.

  • Patent number: 7766380
    Abstract: An airbag is expanded upward on the side of a passenger from a door part. A cover body which covers the airbag is formed by overlaying an outer part made of a hard resin to an inner part made of a soft resin. A supporting piece part is protruded from the cabin external side of the inner part. A to-be-ripped part is formed on the supporting piece part. On expansion of the airbag, the to-be-ripped part is ripped, thereby allowing the door part to move rotationally on the cabin internal side. Therefore, the airbag equipped at the door part can be smoothly expanded along the side face part of the cabin. Thus, an airbag apparatus is improved in appearance.
