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 airbagof a knee airbag deviceis formed of a first inflation portionwhich extends in a vehicle lateral direction along an instrument panelside, and a second inflation portion, which is deployed to a vehicle occupant knee side. A gas supply opening, to which gas ejected from an inflatoris supplied, is disposed at a first inflation portionside. The gas supply opening, and the pair of protection portionsprovided at left and right end portions of knee airbag, are provided on substantially the same line in a vehicle lateral direction, and the first inflation portioncommunicates the two as a gas flow path. Therefore, in a frontal collision, even if a spacebetween the instrument paneland the knees of the vehicle occupant is small, the pair of protection portionscan be quickly inflated and deployed to the small space
