Abstract: A knee airbag device includes an airbag module and an airbag door. The airbag module, which is provided inside a column cover that covers the rear end portion of a steering column, includes gas generation device that generates gas when a collision occurs, and a knee airbag that is inflated and deployed from a folded state when the knee airbag receives the gas from the gas generation device. The airbag door, which is provided in the lower portion of the column cover, is opened when the inflation pressure of the knee airbag is equal to or higher than a predetermined value. When the knee airbag is deployed, at least a portion of the airbag door is positioned between an interfering object that is positioned in an area on the side of the column cover, and at leaser a portion of the knee airbag.

Abstract: The knee-protecting airbag apparatus is mounted on a lower region of a column cover covering a steering column of vehicle projecting rearward from an instrument panel. The airbag (47) folded and housed in a housing emerges and spreads in four directions from the housing for deployment in front of knees of a driver when fed with inflation gas from an inflator (41) that is stored inside the airbag (47) and disposed to the rear side of the housing. Folding of the airbag (47) before being stored in the housing is such that left and right areas of a region (50) attached to the housing is folded on the side of the column side wall (49) to reduce the lateral width L2 of the airbag (47) without superimposing the left and right areas of the mounting region (50) on the inflator (41) in the vertical direction and a folded region (63) on the front side of the mounting region (50) is located in parallel with and in front of the inflator (41).

Abstract: In an air bag device the storing and assembling efficiency of which are improved by retaining the folded shape of an air bag (2) by a band-like member (7), the smooth breaking of the band-like member (7), the improvement of the assembling efficiency of the device and the controlling of the unfolding behavior of the air bag are attained. A breaking portion (8) of the band-like member (7) comprising a woven cloth is formed by breakage aiding holes provided in a row, and the weaving threads (9) of the woven cloth are inclined with respect to the breaking direction of the breaking portion (8). This enables the band-like member (7) to be broken smoothly. Since the band-like member (7) is broken after a cover (5) enclosing the air bag (2) therewith has been ripped open, an excellent bag unfolding behavior is obtained with a rushing-out speed of a central portion of the air bag during an initial period of an unfolding action of the air bag minimized.

Abstract: In a knee protecting airbag device of the present invention, in the lower area inside a column cover(14a), a case (37) housing an airbag is attached to a steering column (3), (7). The steering column includes a movable member(8) for moving toward the front side of a vehicle along the axial direction of the column at the time when an impact on the front of the vehicle acts, and an unmoving stationary member (8), so that the column can absorb the impact when the movable member moves. The case is attached to such an area of the movable member that the case hits the stationary member when the moving member moves and absorbs impact, and the case can be deformed before or at the time of hitting the stationary member so that the moving stroke of the movable member is preserved when it moves.
