摘要： A curtain airbag device includes an airbag including, on one end side in a vehicle front-rear direction, an inflation portion configured to be inflated by a gas, and a non-inflation region into which the gas does not flow. In a state where the airbag is inflated and deployed, the non-inflation region covers a part of an opening among the plurality of openings, and the inflation portion is disposed to surround the non-inflation region, the opening being located at endmost in a vehicle longitudinal direction. In a case where an impactor strikes the opening located at the endmost, the impactor comes into contact with the non-inflation region, and a lower inflation portion of the inflation portion is sandwiched between a lower end of the impactor and the interior materials of the vehicle side portion, the lower inflation portion being located on a vehicle lower side of the non-inflation region.

摘要： The present invention is a side airbag device stowed in a seatback of a vehicle seat, comprising: an inflator arranged on the occupant side of a side frame which is positioned on a side part inside the seatback, that generates expansion gas, and an airbag which expands due to said expansion gas and protects the occupant seated in the vehicle seat. The airbag includes a main chamber that deploys toward the front of the seatback, and a pre-chamber that houses the inflator inside and is connected to the occupant side of the main chamber. Furthermore, an integral joint without gaps is formed by sewing between at least the front edge part of the pre-chamber and the main chamber.

摘要： An apparatus for helping to protect occupants of a vehicle in the event of a collision includes a deployable restraint having a stored, predeployment condition in a vehicle floor. The restraint is deployable from the floor to restrain the feet and/or lower legs of an occupant from swinging forward and upward in response to a vehicle collision. In one configuration, the deployable restraint can include a module comprising an airbag and an inflator for inflating and deploying the airbag. The module can include a door that opens in response to deployment of the airbag and that serves as a reaction surface for the airbag. In another configuration, the deployable restraint can include a restraining panel configured to move to a deployed position extending above the vehicle floor adjacent the occupants lower leg and feet.

摘要： The present invention relates to a vehicular airbag device provided with a configuration comprising: an airbag cushion which is formed in a shawl shape so as to surround and restrict the entire upper body around both shoulders of an occupant as well as the abdominal and pelvic regions in the event of a vehicle collision, and deployed toward both side surfaces of the occupant; and a limiting means which is installed in first and second cushions of the airbag cushion deployed at both sides of the occupant, and provides a supporting force and limits the deployment shape of the first and second cushions at the time of deployment of the first and second cushions. According to the present invention, both side surfaces and the front surface of the occupant are efficiently restricted by improving the lateral strength of the airbag cushion to safely protect the occupant in the event of a vehicle collision.

摘要： A gas generator includes a housing constructed by combining and joining a plurality of shell members. One of the plurality of shell members includes a cylindrical portion and a flange portion. The cylindrical portion is provided with a plurality of gas discharge openings including gas discharge openings different in opening area from one another. The flange portion is shaped such that a distance from an axial line of the cylindrical portion to an outer edge of the flange portion is non-uniform. When a perpendicular line is drawn to the axial line from a maximum outer geometry position in the outer edge of the flange portion most distant from the axial line, a gas discharge opening arranged closest to the perpendicular line is a gas discharge opening other than a gas discharge opening largest in opening area among the plurality of gas discharge openings.

摘要： An inflatable restraint system inflator device having a housing defining an elongated chamber and containing an initial supply of stored inflation gas. An initiator is disposed proximate the first axial end of the housing and an operable closure is disposed proximate the second axial end of the housing. A slidable gas generator assembly is disposed within the chamber between the initiator and the closure and includes a supply of gas generant material reactable upon initiation to produce additional inflation gas. Upon actuation, the initiator and the slidable gas generator assembly cooperate to create a pressure wave to open the closure and to permit release of inflation gas. The slidable gas generator assembly slides within the elongated chamber and gas material reacts to form additional inflation gas.

摘要： An airbag system includes an airbag. The airbag system includes a base defining a track extending from a first end to a second end. The airbag system includes a carrier releasably fixed to the base and removable from the base at the second end. The airbag system includes a tether extending from the carrier and secured to the airbag. The airbag system includes a spring disposed at the first end. The spring is disposed between the carrier and the base. Upon application of a force to the carrier, e.g., via the tether when the airbag is inflated, the carrier is released from the base and compresses the spring. Upon removal of the force, the spring urges the carrier toward the second end where the carrier is ejected.
