ABSTRACT:
In a knee airbag attached to a steering column, the knee airbag is inflated and deployed quickly to a small space between an instrument panel and the knees of a vehicle occupant in a collision.A knee airbag36of a knee airbag device10is formed of a first inflation portion38which extends in a vehicle lateral direction along an instrument panel12side, and a second inflation portion46, which is deployed to a vehicle occupant knee side. A gas supply opening42, to which gas ejected from an inflator22is supplied, is disposed at a first inflation portion38side. The gas supply opening42, and the pair of protection portions46provided at left and right end portions of knee airbag36, are provided on substantially the same line in a vehicle lateral direction, and the first inflation portion36communicates the two as a gas flow path. Therefore, in a frontal collision, even if a space48between the instrument panel12and the knees of the vehicle occupant is small, the pair of protection portions46can be quickly inflated and deployed to the small space48.
