摘要： An airbag device for a front passenger's seat is made compact in a vehicle vertical direction. At an airbag device (10) for a front passenger's seat, due to an inflator (20) being fixed to a front side bottom wall portion (22F) that is formed at a vehicle front side and upper side of a rear side bottom wall portion (22E), the inflator (20) is offset toward the vehicle front side with respect to a central axis (L3) of a case (22). Further, the front side bottom wall portion (22F) is inclined with respect to the rear side bottom wall portion (22E) such that a central axis (L1) of the inflator (20) intersects a normal line (L2) of the rear side bottom wall portion (22E) further toward a vehicle upper side than airbag doors (12, 14), and due thereto, the inflator (20) is tilted. Accordingly, the airbag device (10) for a front passenger's seat can be made to be compact in a vehicle vertical direction as compared with a case in which, for example, the front side bottom wall portion (22F) is parallel to a direction in which the rear side bottom wall portion (22E) extends as shown by a two-dot chain line (L5).

摘要： The decorative panel (34) provided at the instrument panel (12) includes the protruding portion (84) that is engaged with the engagement hole (86) of the airbag door (24), in a state in which the distal end portion (84A) protrudes from the rear surface (24B) of the airbag door (24), and the door decorative portion (78) that is formed integrally with the protruding portion (84) and attached to the front surface (24A) of the airbag door (24) by engaging the protruding portion (84) with the engagement hole (86). The protective plate (36) that includes the protective portion (104) covering the distal end portion (84A) of the protruding portion (84) from the airbag (32) side is provided at the rear surface (24B) of the airbag door (24). When the airbag (32) is inflated and deployed, the airbag (32) is prevented from interfering with the distal end portion (84A) of the protruding portion (84).

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 (86), an upper tether (100) and a lower tether (102) are disposed to sandwich an inflator 70 from above and below. First opening portions (104) and second opening portions (106) for letting gas flow through up and down are alternatingly formed in the upper tether (100) and the lower tether (102). The second opening portions (106) are formed as circular holes with smaller diameters than the first opening portions (104). The second opening portions (106) are disposed at positions opposing the knees (Y) of a small occupant in a sitting state.

摘要： An airbag device capable of reducing the volume of an airbag while still securing occupant restraining capability. The occupant seat airbag device (10) is disposed inside a vehicle front-rear direction curved section (15B) of an instrument panel (15) facing both towards the vehicle top-bottom direction top side and vehicle front-rear direction rear side. The airbag (20) is configured including a pair of outer deployment sections (26) that receive gas supplied from an inflator (22) and inflate and deploy separately from each other in the vehicle width direction, and an inner deployment section (28) formed by a connecting a cloth (34) around substantially the entire periphery of the outer edges of the pair of outer deployment sections (26). An occupant side deployment section (28P) of the inner deployment section (28) does not receive gas supplied from the inflator (22) and deploys as the pair of outer deployment sections (26) deploy.

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).

摘要： An occupant (P) is restrained to a passenger scat (28) by a seat belt apparatus (30). A passenger-seat side airbag (44) is constructed of a first airbag (40) that is deployed along a windshield (46), and a second airbag (42) that is deployed along an upper surface (12A) of an instrument panel (12). A gap opening is formed between the first and second airbags. That is, since the hip and the chest of the occupant (P) are restrained by the seat belt apparatus (30), the airbag apparatus is intended to specifically restrain the head of the occupant (P), which undergoes a larger inertial movement to a vehicular front side, by the first airbag (40) and the second airbag (42). Therefore, the gas capacity of the passenger-seat side airbag (44) as a whole can be reduced.

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： 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).
