摘要： A steering wheel airbag, arranged to cover a steering wheel when inflation is completed, includes: a front-collision receiving surface which is arranged on a side of a driver when inflation is completed, so as to receive the driver moving forward during a head-on collision of a vehicle, the front-collision receiving surface being arranged substantially along a vertical direction to be tilted with respect to a ring surface of the steering wheel when inflation is completed; and arm restraining parts which are arranged near arms of the driver steering a ring part of the steering wheel on both right and left sides of the front-collision receiving surface when inflation is completed, the arm restraining parts coming into contact with the arms during an oblique collision or an offset collision of the vehicle, so as to prevent a movement of the driver to an obliquely front side.

摘要： An airbag for a steering wheel is configured to cover an upper surface of the steering wheel generally all over when inflated. The airbag includes a driver-protection portion that is configured to be deployed towards a driver's seat and restrain a driver, a central protruding portion that is disposed in a vicinity of a center of the driver-protection portion and protrudes towards the driver's seat, a circumferential protruding portion that is disposed in a vicinity of an outer circumferential edge of the driver-protection portion and protrudes towards the driver's seat, and a small protruding portion that is disposed between the central protruding portion and circumferential protruding portion and protrudes towards the driver's seat. The small protruding portion is smaller in protruding amount than the central protruding portion and the circumferential protruding portion.

摘要： An airbag is formed by joining outer edges of an occupant-side wall and a vehicle-side wall each of which is made of a base cloth having flexibility. The occupant-side wall and vehicle-side wall are equal in circumferential length of the outer edge. The occupant-side wall includes a recessed region for receiving a head of a vehicle occupant and an annular raised region that surrounds the recessed region. At least one of the occupant-side wall and the vehicle-side wall includes at least one shortening region that reduces a circumferential length of an outer edge of the base cloth.

摘要： An airbag of a side airbag apparatus includes an upstream inflation portion, which inflates by inflation gas, and deploys frontward at a side of a vehicle seat. An opening is provided at a wall portion of the upstream inflation portion. A pressure regulator valve closes before an occupant is restrained by the upstream inflation portion, thereby restricting the inflation gas in the upstream inflation portion from flowing through the opening. Upon the occupant restraint, the pressure regulator valve cancels the restriction in response to a change in a tensed state of the dividing portion by an external force applied due to the restraint. A tear seam that connects valve body portions of the pressure regulator valve delays the opening time of the pressure regulator valve upon the occupant restraint by the upstream inflation portion relative to the opening time set only by the pressure regulator valve.

摘要： A side airbag apparatus includes an airbag main body. The inside of the airbag main body is divided by a vertical partition including a gas flow restrictor at least into an upstream inflation portion, which is located rearward of the vertical partition and receives inflating gas, and a downstream inflation portion, which is located forward of the vertical partition and receives the inflating gas that has passed through the upstream inflation portion and the gas flow restrictor. The dimension of the vertical partition in the widthwise direction of the automobile seat is set to a dimension that is equal or approximate to the dimension of the airbag main body in the widthwise direction in a case in which the airbag main body is inflated without the vertical partition.

摘要： An airbag includes a high pressure expansion chamber, a low pressure expansion chamber, and a communication passage, which connects the high pressure expansion chamber and the low pressure expansion chamber to each other. A gas supply port, which supplies inflation gas into the airbag, is located inside the low pressure expansion chamber to discharge the inflation gas toward the inside of the communication passage. The communication passage extends from the edge of a communication port, which connects the high pressure expansion chamber and the low pressure expansion chamber, toward the inside of the high pressure expansion chamber. At deployment and inflation of the airbag, the communication passage is located between a seam formed at the outer periphery of the base fabric sheet of the airbag and the gas supply port.

摘要： An airbag device includes a steering wheel a rim portion of which has a longer length in a left and right direction than in a front and back direction, and an airbag mounted on a boss section of the steering wheel. An outer shell of the airbag includes a vehicle-side wall that is configured to be supported by an upper surface of the rim portion when deployed, and a driver-side wall a central region of which is configured to deploy generally vertically for receiving the driver. The airbag as deployed includes, in a rear portion of the vehicle-side wall, a locking inflatable portion that protrudes downward from a vicinity of the upper surface of the rim portion of the steering wheel to be locked by a rear surface of the rim portion and prevent a front portion of the airbag from slipping forward.

摘要： An airbag main body is divided into a first inflation chamber, a second inflation chamber, and a third inflation chamber. The third inflation chamber is inflated beside the lumbar region of an occupant. The vertical partition has a communication hole that connects the first inflation chamber and the second inflation chamber to each other. The airbag main body has a gas passage, which extends in the up-down direction and surrounds at least the gas outlet of an inflator. The gas passage bridges the first inflation chamber and the third inflation chamber. The gas passage has an upper opening, which faces a part of the first inflation chamber that is inflated beside the shoulder region of the occupant. The gas passage also has a lower opening, which faces the third inflation chamber.

摘要： An airbag is manufactured as follows. In a first joining step, peripheral portions of structural fabric portions that are located closer to the main body fabric portions at the installation are joined to the main body fabric portions in a spread state. In a second joining step, a part that is not overlaid onto the structural fabric portions is joined to the main body fabric portions, and a part that is overlaid onto the structural fabric portions is joined only to the structural portions. In a third joining step, peripheral portions of the structural fabric portions that are separated away from the main body fabric portions at the installation are joined to each other.

摘要： An inflation portion of an airbag is divided by a partitioning member into an upstream inflation portion and a downstream inflation portion. Part of the partitioning member forms a pair of overlapping portions overlapped with each other in a band-like shape inside the upstream inflation portion. The overlapping portions are joined to each other by a joint portion located at a boundary between the overlapping portions and non-overlapping portions. The partitioning member includes an opening, which is formed by cancelling the joint between the overlapping portions by the joint portion, and a pressure regulating valve, which includes a pair of valve bodies, which sandwiches the opening. Stress relaxation portions are provided at the overlapping portions. The stress relaxation portions relax stress acting on parts of the joint portion that are adjacent to the opening as the pressure regulating valve is opened.
