An adaptor for connecting a fill tube to an inflator includes a sleeve configured to fit over a discharge end portion of the inflator and to be connected to the inflator. The adaptor also includes an end portion comprising a nipple configured to receive and connect with the fill tube, wherein the sleeve is configured to direct inflation fluid discharged from the inflator toward the nipple, and the nipple is configured to direct the inflation fluid into the fill tube.

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.

An airbag module (10) comprises an airbag (12) including two outer wall layers (18) which are interconnected at a circumferential joint (22) along a circumferential edge (20) of the airbag (12) and which delimit an interior of the airbag (12) fillable with gas, wherein an opening (26) which is in fluid communication with the fillable interior of the airbag (12) is provided in the circumferential joint (22), and a plug (14) which is permanently inserted in the opening (26). The plug (14) includes a passage (16), and an outer circumferential surface (32) of the plug (14) is sealed against an inner edge (28) of the opening (26).

In an assembly (20) of an elongate inflator (10) which has an outer housing (14) with outflow openings (18) spread along the circumference (U) and defining an outflow area (16) and an outflow direction, and of a clamp-type diffusor (22) enclosing the outflow area (16), the diffusor (22) includes a central receiving opening (24) into which the outer housing (14) protrudes so that the diffusor (22) circumferentially encloses an axial portion of the outer housing (14) which comprises the outflow area (16). At the inner side of the diffusor (22) delimiting the receiving opening (24) at least one bearing surface (34) and at least one gas guiding surface (30) are provided, wherein the bearing surface (34) bears directly against the outer housing (14) of the inflator (10) and the gas guiding surface (30) is radially spaced apart from the outer housing (14) while forming at least one collecting chamber (30) into which gas flowing out of the outflow area (16) is flowing. The collecting chamber (32) opens into at least one outlet opening (36) through which gas exits the diffusor (22) in an outlet direction (RD) transversely to the outflow direction out of the inflator (10).

An adaptive force vehicle airbag (AFVA) system includes airbag(s) stowed in a compressed state within an interior of a vehicle. An impact sensor detects a change in motion of the vehicle indicative of a collision. Selectable force gas generator(s) (SFGGs) gas-generating propellant cells that are individually fired. The SFGGs have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate at least one of the airbag(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the SFGGs. The controller enables the AFVA system to: (i) receive an inflation signal from the impact sensor; and (ii) fire a selected number of the gas-generating propellant cells to at least partially inflate the at least one airbag.

An airbag apparatus for a vehicle includes an inflator, an airbag configured to be expanded and deployed from an instrument panel when supplied with gas so as to be positioned on a front side of an occupant, and a flow guide cloth disposed inside the airbag. The flow guide cloth is configured to be expanded and deployed when the gas flows into the flow guide cloth and discharge the gas into the airbag. A rear end portion is spaced from a rear wall of the airbag. A rear outlet is disposed in the rear end portion and configured to discharge the gas into a rear end portion of the airbag. A front outlet is disposed in a front portion and configured to discharge the gas into a front portion of the airbag. An opening area of the rear outlet is larger than an opening area of the front outlet.

A diffuser includes a first tube and a second tube. The first tube includes a key and defines a first opening. The second tube is inserted through the first opening. The second tube defines a notch. The key is inserted into the notch.

A curtain airbag apparatus which can smoothly expand an airbag cushion even with a low gas ejection pressure of an inflator. A curtain airbag apparatus according to an embodiment includes: an outer cushion provided on an upper side of a pillar constituting a vehicle along a forward and backward direction of the vehicle to be expandable; a plurality of inner cushions which are fixed to an inner side of the outer cushion along the forward and backward direction of the vehicle to be spaced apart from each other and are independently expandable; and inflators disposed in the plurality of inner cushions, respectively, so as to eject gas into the inner cushions so that the inner cushions are expanded by generation of the gas.

Gas generator comprising: a first chamber having first pressurized gases and a first outlet port, a second chamber with second pressurized gases and a second outlet port, a diffusion zone, arranged to receive and diffuse towards an airbag the first pressurized gases and the second pressurized gases, wherein the first pressurized gases and the second pressurized gases are arranged to react together once they are mixed, characterized in that the gas generator comprises at least one deflector arranged to impose on the first pressurized gases a first discharge trajectory in the separate diffusion zone of a second discharge trajectory of the second pressurized gases.

An in-seat airbag device including an airbag main body having a front-rear chamber that expands past a side of a head of a passenger toward a seat front side and is disposed at the side of the head of the passenger, and a distal end chamber that expands from a seat front side end portion of the front-rear chamber toward a seat width direction inner side and is disposed at a seat front side of a face of the passenger, wherein the airbag main body and a seatback frame are connected by a force limiter mechanism that moves the airbag main body toward a seat front side when a load, which is toward a seat front side and is applied to the airbag main body, exceeds a predetermined threshold value at a time of head restraining when the head of the passenger is restrained.
