摘要： A knee airbag device (10) i includes a column cover (46) that covers a rear end portion of a steering column (12) from below; and an airbag module (30). The airbag module (30) is disposed in a column lower cover (48) and includes a gas generation portion (34) that generates gas and a knee airbag (36) that is housed in the airbag module (30) in a folded state, and is inflated and deployed by the gas supplied by the gas generation portion (34). The airbag module (30) is connected to the steering column (12) by a snap-fit action.

摘要： 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 a 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 least a portion of the knee airbag.

摘要： The knee-protecting airbag apparatus (M1) includes an airbag (61) folded and housed in a lower area (16a) inside the column cover (16). The airbag (61) pushes and opens a door section (34) on the column cover upon deployment. When the door section (34) is thus opened, a door (35) of the door section (34) blocks off an allowance gap (H) formed between an outer circumference (18) of the column cover (16) subjected to position adjustment and a lower area (11a) of a peripheral region (11) of an installation opening (10) on a dashboard (7) for installing the column cover (16) by locating a rear edge region (36) of the door (35) to abut on a rear side (12) of the dashboard (7) or the lower area (11a) of the peripheral region (11) of the installation opening (10) on the rear side (12) of the dashboard (7).

摘要： In a knee protecting airbag device of the present invention, in the lower area inside a column cover, a case housing an airbag is attached to a steering column. The steering column includes a movable member 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, 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.

摘要： 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).
