  • Patent number: 12109974
    Abstract: A pedestrian protection device includes a left airbag and a right airbag that are disposed in a vicinity of a rear end of a hood panel in a vehicle, and are arranged in parallel on vehicle width direction sides. The left airbag and the right airbag each include a cowl cover portion that is disposed following the vehicle width direction and covers an upper face side of a cowl. The cowl cover portions have end portion regions disposed coinciding with each other on up-down direction sides on end sides that are in proximity to each other. At least one of the end portion regions is configured in such a way that an internal pressure when inflation is completed is raised higher than that of a general region.

  • Patent number: 12063988
    Abstract: A wearable airbag device for protecting the hip of a wearer includes an airbag that is formed of a sheet material having flexibility and is adapted to be put on a circumference of the pelvis of the wearer. The airbag is inflatable with an inflation gas. The airbag includes: a mounting portion that is adapted to be disposed at a region to be wrapped around the pelvis at airbag deployment; two protecting portions each of which is configured to extend downward from the mounting portion and cover an outer side of a targeted body part of the wearer at airbag deployment, the targeted body part being left and right trochanters of femurs; and a means for suppressing each of the protecting portions from expanding and floating away from the targeted body part at the lower end at deployment of the protecting portion.

  • Patent number: 10864879
    Abstract: Ahead protection airbag device includes an airbag. The airbag includes: a hag main body; and an attachment member configured to attach the bag main body to a predetermined attachment part. The attachment member includes: an attachment substrate; a neck part protruding from the attachment substrate; and an engaging head part arranged with being bulged at a tip end of the neck part. The bag main body has an insertion hole in which the neck part is inserted so as to enable the engaging head part to protrude from an outer surface-side of a folded body of the bag main body. The attachment substrate is arranged at a backside of a peripheral edge of the insertion hole so that the attachment member is attached to the bag main body.

  • 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.
