A vehicle side airbag device including an inflator, a side airbag, and a duct is installed at a side section on a vehicle width direction outer side of a seatback of a vehicle seat configured to restrain an occupant using a three-point seatbelt. The side airbag receives a supply of gas from the inflator in a vehicle side-on collision. As a result, a waist chamber is inflated and deployed from a lower portion of the side section toward a side of a waist of the occupant, and a head chamber is inflated and deployed from an upper face side of the side section toward a side of a head of the occupant. The duct extends along a vertical direction of the side airbag inside the side airbag, and is configured to guide gas from the inflator into the waist chamber and into the head chamber.

An airbag device includes a seat frame that forms a skeleton of a vehicle seat on which an occupant of a vehicle sits; an airbag that is disposed on a backrest portion that supports a back of the occupant in the vehicle seat and that is deployed by supply of gas; and a gas generator that is disposed at a seating surface portion that supports buttocks of the occupant in the vehicle seat and that generates gas to be supplied to the airbag; where a part that is a portion of the seat frame and includes at least a portion of a back frame forming a skeleton of the backrest portion, is formed as a flow tube that connects to the airbag to supply gas generated by the gas generator to the airbag.

An airbag assembly for a vehicle is provided that includes a housing coupled to the support structure of a vehicle. An airbag module is coupled to and supported by the housing. The airbag module includes an airbag deployable from an undeployed condition to a deployed condition, and an inflator configured to inflate the airbag from the undeployed condition to the deployed condition. An air duct that is configured to transmit an airflow is at least partially integrally coupled to the housing.

The invention describes an airbag (10), in particular a head side airbag (10) or a head-thorax side airbag, including at least two opposite fabric layers (12, 14) which form at least one inner wall (13) and one outer wall (15) of the airbag (10), wherein the airbag (10) is manufactured in one piece by a multi-layer weaving process in which the fabric layers (12, 14) are interwoven at least in a peripheral region (16), with a gas generator mount (18) for an external gas generator (20) being disposed in either of the two fabric layers (12, 14). The invention further describes an airbag module (8) comprising an airbag (10) according to the invention as well as a method for manufacturing a one-piece-woven airbag (10) and a method for manufacturing an airbag module (8).

A self-adaptive air bag blocking device is disclosed. The device includes an air bag, a first gas conveying pipe and a second gas conveying pipe, wherein an air chamber is formed in the air bag, a ring-shaped abutting surface is formed on the peripheral side of the air bag, so that the abutting surface abuts against a mouth of a container. The first gas conveying pipe is communicated with the air chamber and the outer part of the air bag, so that air enters the air chamber to enable the air bag to expand. The abutting surface is elastically deformed and tightly abuts against the inner wall of the container to form air-tight abutment, and the second gas conveying pipe is arranged on the air bag, so that air enters the container through the second gas conveying pipe, and thus the working liquid is discharged.

A coupling structure includes a first coupling portion formed by one end portion of a first tube, and a second coupling portion formed by one end portion of a second tube, and is configured such that the first coupling portion is inserted in the second coupling portion, the first coupling portion and the second coupling portion are coupled, with the second tube being pivotable with respect to the first tube, and a gap is formed between an outer surface of the first coupling portion and an inner surface of the second coupling portion in a first state in which a fluid is not flowing through the flow path, and in a second state in which the fluid is flowing through the flow path, pressure of the fluid causes the first coupling portion to deform to expand toward an outer side of the flow path to reduce the gap.

In an assembly group comprising a cap of a tubular gas generator and a deflector element that deflects gas flowing out of at least one outflow opening of the cap to at least one discharge opening of the deflector element, a deflection surface of the deflector element is arranged radially outwardly of the outflow opening. At least two securing arms of the deflector element extend through the outflow opening and engage behind an edge defining the outflow opening on an inside in a positive connection with the cap. The cap is fixed firmly to an axial end of the tubular gas generator. Subsequently, the deflector element is slid from an outside of the cap with its securing arms through the outflow opening, the securing arms forming a positive connection with the edge of the outflow opening which fixes the deflector element firmly to the cap.
