The present invention provides a gas generator, including: in a cylindrical housing, a cup-shaped member separating the combustion chamber in a cylindrical housing main body portion from the diffuser portion, the cup-shaped member being disposed such that a bottom surface thereof is positioned on the side of a first end of the cylindrical housing main body portion, an opening thereof is positioned on the side of a second end of the cylindrical housing main body portion, and a first gap which allows the combustion chamber to communicate with the diffuser portion, is formed between the the cup-shaped member and an inner wall surface of the cylindrical housing main body portion; and a filter disposed in a space surrounded by the cup-shaped member and the diffuser portion, the filter being a cup-shaped filter having a base, a circumferential wall and an opening, and the filter being provided such that, the base of the filter abuts on a closed end surface of the diffuser portion, an end surface of the opening of the filter faces the bottom surface of the cup-shaped member, and the circumferential wall of the filter abuts, from inside, on the circumferential wall of the cup-shaped member including a plurality of the communication holes, and being disposed with a second gap formed between the filter and the gas discharge ports.

A seatbelt airbag for a vehicle is provided. The airbag is inflated in a seatbelt to restrain an occupant to reduce an injury to the occupant caused by the seatbelt. Particularly, since the airbag is locally inflated at occupant's shoulder and hip which are susceptible to injury by the seatbelt, an inflation speed is controlled, an impact is minimized, and the occupant may be restrained in the seat more rapidly and stably.

According to an embodiment of the present invention, provided is a closing structure of a pressure-resistant container in which an opening of a metallic cylindrical container is closed by a metallic closing member, the closing member including a closing part, the closing part including a first surface, a second surface on an opposite side to the first surface in a thickness direction, and a circumferential surface part between the first surface and the second surface, and having a same shape as that of the opening and having a size enabling insertion thereof into the opening. The closing structure includes: the closing member that is inserted to be at an inside of the opening of the cylindrical container, with the second surface facing inside of the cylindrical container; an annular deformed part that is deformed, with a peripheral wall part on the opening of the cylindrical container abutting against the first surface of the closing part of the closing member and a first annular corner part at a boundary between the first surface and the circumferential surface part; and a welded part where a contact portion between the first annular corner part of the closing part of the closing member and the annular deformed part is welded from outside.

A knitted seat trim cover for use on a vehicle seat equipped with an airbag assembly includes a first knitted panel with a first edge and a second knitted panel with a second edge. The first edge is positioned adjacent the second edge to define an airbag deployment zone. The seat trim cover also includes a pocket panel integrally knit with the first knitted panel and the second knitted panel. The pocket panel defines an airbag pocket configured to hold at least a portion of the airbag assembly.

A control valve provided in a communicating portion restricts the supply of gas from a front main chamber to a rear delay chamber during an initial stage of inflation and deployment of the front main chamber. The control valve releases restriction of the supply of the gas from the front main chamber to the rear delay chamber during the later stage of inflation and deployment of the front main chamber.

The invention relates, among other things, to a gas generator for generating a driving gas for a vehicle safety device, wherein the gas generator comprises: an ignition device; fuel which, after ignition using the ignition device, generates the driving gas; an at least partially tubular carrier element, in the tube interior of which a combustion chamber for the fuel is located; an injection-moulded body which fixes the ignition device in the connection hole and is located with an inner portion inside the carrier element and with an outer portion outside the carrier element; a feed pipe which is connected to a pipe end of the carrier element and which conveys the driving gas out of the combustion chamber; and a lid sealing the combustion chamber.

A side airbag device including: a bag-shaped airbag that deploys from a lateral portion of a vehicle seat toward a front side of a vehicle; and an inflator that supplies inflation gas into the airbag. The airbag has, at least at a lower portion thereof, a lower tuck-in region tucked into the airbag. Further, at least a part of the lower tuck-in region is folded into a fan shape and forms a radial folded region folded into a pleated shape along a line extending rearward in a radial direction from a central point of the fan shape positioned on a front side of the airbag.

An airbag apparatus may include: a first chamber connected to an inflator, and supporting the head of a passenger in case of a head-on collision of a vehicle; a second chamber connected to one side of the first chamber, and suppressing the head of the passenger from moving in a diagonal direction in case of an oblique collision of the vehicle; a communication tube formed on the first chamber to introduce gas of the first chamber into the second chamber, and having a tightening channel formed along the circumference thereof; and a valve tether including: a tether ring installed through the inside of the tightening channel; and a tether puller connected to the tether ring to pull the tether ring in one direction, and closing the communication tube by pulling the tether ring when the first chamber is completely deployed.

Airbag cushion assemblies for aspirating ambient air and related assemblies, methods, and components. Some embodiments may comprise an aspirating airbag cushion assembly comprising an airbag cushion housing, an aspiration housing coupled to the airbag cushion housing and comprising an aspiration inlet configured to allow for receipt of ambient air into an airbag cushion, and an inflation module slidably coupled to the aspiration housing. The inflation module may comprise an inflator and one or more inflation tubes or other conduits fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into the airbag cushion.

Device for fixing a connection to an OPW airbag, with an expansion sleeve (2), with a plurality of expansion shells (4), and a mandrel (6) extending longitudinally through the expansion sleeve (2) having a stretching piece (8) arranged in the vicinity of the expansion shells (4), the outer diameter of which stretching piece is greater than the inner diameter of the expansion shells (4).
