  • Patent number: 11084450
    Abstract: When a curtain airbag inflates and expands, an independent portion inside a slit portion inflates and expands toward a vehicle lower side toward a gap between a seat back and a center pillar garnish. If the independent portion interferes with the seat back, the independent portion inflects in the vehicle width direction. Meanwhile, regions of the curtain airbag other than the independent portion inflate and expand toward the vehicle lower side without being affected by the position of the independent portion.

  • Patent number: 10836342
    Abstract: An airbag includes a bag body and an inlet port section of inflation gas. As a gas receivable region, the bag body includes a front main inflatable region, a rear main inflatable region, a feed path that feeds the inflation gas from the inlet port section to the front and rear main inflatable regions, and a sub inflatable region that absorbs the gas from the front main inflatable region when a pressure of the front main inflatable region soars. A front partitioning region partitions the front main inflatable region from the sub inflatable region. The front partitioning region is disposed in front of a front end of an upper partitioning region in an island-like fashion remote from other uninflatable region so as to provide, at the rear of and there beneath, one each communication passage that provides gas communication between the front main inflatable region and the sub inflatable region.

  • Patent number: 10562481
    Abstract: An airbag package of an airbag for head protection includes a rolled portion formed by rolling a skin material of the airbag as laid flat, and a compressed region in which a void space formed at the center of the cross-sectional surface of the rolled portion has been crushed due to compression. The rolled portion includes, in the cross-sectional surface, an upper layered portion, a lower layered portion, and a pair of side layered portions that are disposed around the center of the cross-sectional surface of the rolled portion and each have layers of the skin material. In the compressed region, each of the side layered portions bends generally at the center in an up and down direction such that the bent regions butt against each other and are packed between the upper layered portion and the lower layered portion in such a manner as to fill the void space.

  • Patent number: 9950686
    Abstract: An occupant protection apparatus is provided with a first airbag device having a window airbag that protects an occupant in a vehicle and a second airbag device having an adjacent airbag that completes inflation to contact the window airbag for which inflation is completed, thereby protecting the occupant. Where the internal pressure of an inflation chamber at the contact site during contact with the adjacent airbag by the window airbag is P1 and the internal pressure of the adjacent airbag is P2, P1<P2 is satisfied. The wrap amount of the inflation chamber with the adjacent airbag is set as a proportion of a calculated value or less of a predetermined numeric expression.

  • Publication number: 20180086302
    Abstract: An airbag is deployed and inflated by inflating gas discharged from a plurality of gas discharge portions. The airbag is divided into a plurality of inflation chambers. At least one of the inflation chambers is an independent inflation chamber that restricts flow of inflation gas to and from adjacent ones of the inflation chambers. Two or more of the inflation chambers including the independent inflation chamber are discharge inflation chambers, each including the gas discharge portion. The gas discharge portions include a first gas discharge portion that starts discharging the inflation gas at a first timing and a second gas discharge portion that starts discharging the inflation gas at a second timing, which differs from the first timing. The first discharge portion is arranged in at least one of the independent inflation chambers.
