摘要： It is an object to ensure that, even when knee regions of an occupant are in a near state with respect to a storage section of a knee airbag at the time of a frontal collision of a vehicle, the knee regions can be restrained appropriately by the knee airbag.
A knee airbag 14 stored in a folded state in a glove box door 22 (a storage section) receives a supply of a gas at the time of a frontal collision of a vehicle 18 and inflates and deploys toward knee regions 36K of an occupant 36 seated in a front passenger seat 12 (a vehicle seat). At this time, when the knee regions 36K of the occupant 36 are in a near state with respect to the glove box door 22, the gas inside the knee airbag 14 becomes ventable to the outside from a vent hole 16. The vent hole 16 appropriately vents this gas from the inside of the knee airbag 14, and the reaction force of the knee airbag 14 with respect to the knee regions 36K are reduced.摘要翻译： 本发明的目的是确保即使在车辆的前方碰撞时，即使是乘员的膝部区域相对于膝部安全气囊的收纳部处于接近状态，也可以通过适当地约束膝部区域 膝盖气囊 以折叠状态存储在手套箱门22（存储部）中的膝部安全气囊14在车辆18的正面碰撞时接收气体供给，并且向乘坐者36的膝部区域36K充气并展开 在前乘客座椅12（车辆座椅）中。 此时，当乘员36的膝部区域36K相对于手套箱门22处于接近状态时，膝盖气囊14内的气体从通气孔16向外部通气。通气孔16适当地 从膝部安全气囊14的内部排出该气体，膝部安全气囊14相对于膝部区域36K的反作用力减小。

摘要： A knee airbag device for a vehicle, configured in such a manner that, when a knee airbag is inflated and expanded with the knees of a vehicle occupant located close to an airbag door, a load to the lower legs is reduced. A first tear section (100) for expanding a first airbag door (108) in the vehicle's top-bottom direction and a second tear section (102) for expanding a second airbag door (112) in the vehicle's lateral direction are formed on the rear surface side of a glove-box-door outer member (24). The first tear section (100) is composed of a left and right pair of vertical tear sections (104) and a first horizontal tear section (106). The second tear section (102) is composed of second lateral tear sections (110).

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.摘要翻译： 在膝部安全气囊通过在乘客的膝部靠近气囊门等的状态下膨胀而展开时的胫部上的负荷被减轻。 在膝部安全气囊（86）的内部，从上方和下方夹着充气机70配置上部系绳（100）和下部系绳（102）。 用于使气体上下流动的第一开口部分（104）和第二开口部分（106）交替地形成在上部系绳（100）和下部系绳（102）中。 第二开口部分（106）形成为具有比第一开口部分（104）更小直径的圆形孔。 第二开口部（106）配置在就座状态下的与小乘员的膝盖（Y）相对的位置。

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： 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： 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： A vehicle side airbag device (40) including an inflator (44), a side airbag (46), and a duct (48) is installed at a side section on a vehicle width direction outer side of a seatback (16) of a vehicle seat (12) configured to restrain an occupant using a three-point seatbelt (32). The side airbag receives a supply of gas from the inflator (44) in a vehicle side-on collision. As a result, a waist chamber (46D) is inflated and deployed from a lower portion of the side section toward a side of a waist (W) of the occupant, and a head chamber (46A) is inflated and deployed from an upper face side of the side section toward a side of a head (H) of the occupant (P). The duct extends along a vertical direction of the side airbag inside the side airbag, and is configured to guide gas from the inflator (44) into the waist chamber (46D) and into the head chamber (46A).
