Abstract:
1. A knee protecting airbag device comprising: a case which is arranged in the lower area inside a column cover which covers a steering column and which is attached to said steering column; an airbag folded and housed in said case; and an inflator for feeding an inflating gas to said airbag, wherein said airbag is inflated to expand while admitting the inflating gas discharged from said inflator, the airbag protrudes from said column cover and thus can protect the knees of a seated driver, wherein said steering column includes a movable member which moves toward the front side of the vehicle along the axial direction of the steering column at the time when there is an impact on the front of the vehicle, and an unmoving stationary member, and is configured so that the steering column can absorb the impact when said movable member moves, and wherein said case is attached to such an area of said movable member that the case hits said stationary member when the steering column moves to absorb the impact, and the case can be deformed before or at the time of hitting said stationary member so as to preserve the moving stroke of said movable member when it moves.
