摘要： A load on the shins when a knee airbag is deployed by inflating in a state in which the knees of an occupant are proximate to an airbag door or suchlike is moderated. Inside a knee airbag, an upper tether and a lower tether are disposed to sandwich an inflator from above and below. First opening portions and second opening portions for letting gas flow through up and down are alternatingly formed in the upper tether and the lower tether. The second opening portions are formed as circular holes with smaller diameters than the first opening portions. The second opening portions are disposed at positions opposing the knees of a small occupant in a sitting state.

摘要： 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 airbag 36 of a knee airbag device 10 is formed of a first inflation portion 38 which extends in a vehicle lateral direction along an instrument panel 12 side, and a second inflation portion 46, which is deployed to a vehicle occupant knee side. A gas supply opening 42, to which gas ejected from an inflator 22 is supplied, is disposed at a first inflation portion 38 side. The gas supply opening 42, and the pair of protection portions 46 provided at left and right end portions of knee airbag 36, are provided on substantially the same line in a vehicle lateral direction, and the first inflation portion 36 communicates the two as a gas flow path. Therefore, in a frontal collision, even if a space 48 between the instrument panel 12 and the knees of the vehicle occupant is small, the pair of protection portions 46 can be quickly inflated and deployed to the small space 48.

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： A passenger-seat airbag (32) includes a pair of left and right airbags (44, 46), and a root portion (48) that is connected to both of the left and right airbags (44, 46). When the passenger-seat airbag (32) is provided in a vehicle, an airbag folded portion (62) that forms the left and right airbags (44, 46) is positioned closer to the rear of the vehicle than the root portion (48) is, and a slack portion (49) that forms the root portion (48) is made upright along the airbag folded portion (62), and is positioned closer to the front of the vehicle than the airbag folded portion (62) is. Thus, the slack portion (49) is expanded and deployed toward a windshield earlier to form “a wall”. Then, the left and right airbags (44, 46) are stably deployed toward a passenger seat (toward the rear of the vehicle).

摘要： A vehicular airbag device includes an airbag and an opening degree change portion. The airbag is folded and accommodated in an accommodation portion provided in front of a vehicle seat. The airbag is deployed toward an occupant seated in the vehicular seat by being supplied with a gas when a head-on collision occurs, and has a vent hole that allows the gas to be discharged in restraining the occupant. The opening degree change portion changes an opening area of the vent hole in accordance with a direction of impact of an upper body of the occupant with the airbag during deployment of the airbag.

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 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.

摘要： When a knee airbag is deployed, a lid, which is provided in a column cover that covers a steering column, is opened by the deployment pressure of the knee airbag. Thus, an opening, through which the knee airbag expands, is formed to extend in the lower wall portion and the right and left side wall portions of the column cover. At this time, an opening amount regulation portion regulates the opening amount of the lid so that the knee airbag is deployed toward areas on right and left sides of the column cover.

摘要： A knee airbag device includes a knee airbag that is disposed in a folded state inside a steering column cover. When the knee airbag receives gas, the knee airbag is inflated and deployed from the inside of the steering column cover toward the knee portion of an occupant. The knee airbag includes an instrument panel-side foundation cloth positioned close to an instrument panel when the knee airbag is deployed, an occupant-side foundation cloth positioned close to the occupant when the knee airbag is deployed, and a first strap and a second strap that connect the instrument panel-side foundation cloth and the occupant-side foundation cloth. When the knee airbag is deployed, the first strap is positioned above the second strap and the length of the first strap in a vehicle-longitudinal direction is set to be larger than the length of the second strap in the vehicle-longitudinal direction.
