Patent ID: 8511710

Claim:
An airbag device comprising: a gas generation device that is disposed inside a portion of an instrument panel facing a vehicle top-bottom direction top side and a vehicle front-rear direction rear side; a pair of outer deployment sections that receive gas supplied from the gas generation device and inflate and deploy separately from each other in a vehicle width direction; an inner deployment section that connects the pair of outer deployment sections at least at the vehicle front-rear direction rear side, the vehicle top-bottom direction top side and a vehicle top-bottom direction bottom side, the inner deployment section deploying as the pair of outer deployment sections are deployed; a partitioning cloth that partitions the closed space into a first space at a vehicle front-rear direction front side and a second space at the vehicle front-rear direction rear side, the partitioning cloth being configured such that gas from the gas generation device is supplied to the first space and gas from the gas generation device is not supplied to the second space; and a lower side deployment section that passes through the inner deployment section and is connected to the partitioning cloth, the lower side deployment section receiving supplied gas so as to inflate and deploy between knees of an occupant and the instrument panel; wherein the inner deployment section is configured by connecting peripheral edges of the pair of outer deployment sections with a single cloth so as to deploy to form a closed space between the pair of outer deployment sections, and the partitioning cloth is formed with a gas supply hole through which gas from the gas generation device is caused to flow through the first space into the lower side deployment section.
