An assembly includes a seatbelt and an inflation chamber connected to the seatbelt. The inflation chamber is inflatable from an undeployed state to a deployed state. The inflation chamber includes a first inflation chamber and a second inflation chamber. The first inflation chamber is positioned above the second inflation chamber.

An airbag device includes a curtain airbag that is inflated by gas supplied to an inside of the curtain airbag, and that is configured to be deployed to a vehicle width direction outer side of an occupant seated in a vehicle seat, a main airbag that is inflated by gas supplied to an inside of the main airbag, and that is configured to be deployed from an instrument panel side to a front side of the occupant seated in the vehicle seat, and an auxiliary airbag that is inflated by gas supplied to an inside of the auxiliary airbag, and that is configured to be deployed between a vehicle width direction inner portion of the main airbag and an instrument panel.

A side airbag device for a vehicle includes a lower chamber and an upper chamber to protect a passenger from a side impact in the event of a vehicle collision. The upper chamber is bent towards the passenger by a connecting tether to support a passenger's neck region and prevent the neck from being twisted. The restraint belt forms an inserting space in front of a passenger when the upper chamber is bent so that a passenger's shoulder region is inserted into the inserting space when the passenger is moved forwards by collision inertia. The passenger's shoulder region is surrounded and supported by the restraint belt so that the passenger's body is restrained by a seat. A passenger is protected from impact and simultaneously the passenger is restrained by the seat to minimize an injury.

A door assembly includes a door trim panel, a first airbag coupled to the door trim panel and inflatable to an inflated position, a second airbag coupled to the door trim panel and spaced in a vehicle-rearward direction from the first airbag and inflatable to an inflated position, and an inflator in simultaneous fluid communication with both the first and second airbags when the first and second airbags are in the inflated positions.

An inflation assembly for use within a vehicle. The inflation assembly is configured to deliver gas from a pressure source to the one or more inflatable devices. The inflation assembly includes a fitting that engages with the pressure source and receives gas from the pressure source. The fitting includes outlet ports that are oriented to direct the gas away from the fitting and into hoses that lead to one or more inflatable devices. The outlet ports are configured to release gas in outward directions such that reactive forces that are applied to the fitting by the released gas are neutralized. This prevents the pressure source from moving and potentially injuring a person or damaging the vehicle.

A vehicular seat includes a first conduit that guides gas from a first gas generator to a first airbag, the first conduit includes a first flexible tube portion having flexibility and disposed along a first side end inside at least one of a seat surface or a seat back, and the first flexible tube portion expands to deform the seat body when the gas supplied to the first airbag from the first gas generator passes through the first flexible tube portion.

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.

A side inflatable airbag assembly for a vehicle is disclosed. Inflatable airbag assemblies may provide protection for an occupant in a vehicle collision event. In a side collision event, or other event producing lateral movement of the occupant relative to the vehicle, the disclosed inflatable airbag assembly may receive and support the occupant during ride down so as to prevent or minimize injury resulting from impact with a vehicle door, sidewall, center console, or other vehicle structure disposed lateral to the vehicle seating position. The disclosed airbag may differentially support the occupant buy providing varied degrees of support for the shoulder and pelvis, and the torso, which may be particularly beneficial to an elderly occupant whose bones may be more susceptible to some injury types and modes as a result of age-incident health issues.

An active bolster for a vehicle is provided, wherein the bolster comprises an expansible hollow interior that is inflatable and is self-supporting in both an inflated and in an uninflated position. The bolster has an inflator module for inflating the expansible hollow interior. The bolster has an inner wall for projecting inwardly into the vehicle and away from the side of the vehicle on inflation of the expansible hollow interior. The bolster may have a relatively non-expansible component located between a first expansible chamber and a second expansible chamber. The bolster may comprise an outer wall having an attachment portion for attaching the outer wall to a portion of the side of the vehicle.

Aspects of the disclosure provide for airbag systems suited for autonomous vehicles. Such an airbag system may include a first chamber, a second chamber, a dual-stage inflator, an orifice blocker mechanism and a control module. The dual-stage inflator may be in fluid communication with the first chamber via a first orifice and in fluid communication with the second chamber via a second orifice. The orifice blocker mechanism may be configured to block and unblock gas flow from the second orifice to the second chamber. The control module may be configured to activate the dual-stage inflator in order to inflate one or both of the first chamber and the second chamber with gas based on a position of the orifice blocker mechanism relative to the second orifice.
