A system includes an airbag including a first lobe, a second lobe, a first tether connected to the first lobe, and a second tether connected to the second lobe, a seat rotatable relative to the airbag from a first position to a second position, and a computer programmed to, based on whether the seat is in the first position or the second position, release one of the first tether or the second tether.

A seat airbag for a vehicle includes: a cushion including: a main part provided along an edge of a seatback of a vehicle, the main part spreading to a front part of the seatback so as to cover a passenger when spreading and open on a front part of the main part while covering opposite side parts and an upper part of the passenger; and an extension part connected to an open front end of the main part and shrinking so as to protect a front part of the passenger; and a protection tether connected to the extension part and shrinking the extension part by pulling the extension part during spreading of the main part.

An airbag assembly includes a housing and an airbag. The airbag is supported by the housing and includes a vent. The airbag assembly includes a tether supported by the housing and fixed to the vent. The airbag assembly includes a tether release operatively coupled to the tether. The airbag assembly includes a tether retractor supported by the housing and fixed to the tether.

An apparatus for helping to protect an occupant of a vehicle includes an airbag configured to be mounted to a seat back of a vehicle seat. The airbag is inflatable between the seat back and an adjacent side structure of the vehicle to one of a first deployed condition in which the airbag is configured for a non-reclined condition of the vehicle seat, and a second deployed condition in which the airbag is configured for a reclined condition of the vehicle seat. The airbag is configured to deploy to the first deployed condition in response to determining a non-reclined condition of the vehicle seat and to the second deployed condition in response to determining a reclined condition of the vehicle seat.

An air-bag apparatus includes: a bag body that is provided on a vehicle seat and that is inflated and expanded at a time of an impact input and prevents at least an upper part of a body of an occupant seated on the vehicle seat from being separated from a seat back of the vehicle seat; an inflator that supplies a gas to the bag body at a time of an impact input; a body size detection part that detects a body size of the occupant seated on the vehicle seat; and an expansion degree adjustment part that adjusts a degree of an inflation expansion of the bag body in accordance with the body size of the occupant detected by the body size detection part.

An airbag module assembly has an airbag cushion with at least one vent, a housing structure for receiving the airbag cushion, a housing cover for attachment to the housing structure, a vent connector connected to the vent, a pin puller mechanism with a retractable pin, and a flexible conduit extending from the airbag cushion adjacent the vent to the pin puller mechanism. The vent connector extends inside the conduit to a looped end for attachment to the retractable pin. The vent connector can be a rope or wire. The vent is initially in a closed position during deployment of the airbag. The airbag cushion is folded about the conduit during assembly and the vent connector is configured to pass through the flexible conduit when the airbag cushion is folded.

A vehicle includes a seat having a seat bottom and defining a seat-forward direction. The vehicle includes an interior component. The vehicle includes an airbag supported by the interior component and inflatable to an inflated position having a main body elongated along a vehicle-longitudinal axis and an extension extending from the main body transverse to the vehicle-longitudinal axis in front of the seat bottom relative to the seat-forward direction.

An airbag has a main bag portion that is provided with an occupant protective surface which is disposed to face the occupant and an auxiliary bag portion that can be disposed on the left side of the storage part, between the main bag portion and a vehicle body-side member, when the inflation is completed. The auxiliary bag portion is configured to enable an inflating gas to flow into an inside thereof through the main bag portion, is configured to be inflated under control of a control mechanism in association with a collision mode of a vehicle, and is configured to be interposed between the main bag portion and the vehicle body-side member and to be capable of pushing a region of the occupant protective surface on a side of the auxiliary bag portion, which is inflated, toward a side of the occupant, when the inflation is completed.

An airbag apparatus includes an airbag and an airbag controller. The airbag is disposed in a movable member and configured to be able to deploy in different sizes in a front-to-back direction of an automobile. The movable member can move in the front-to-back direction in front of a passenger in the automobile. The airbag controller is configured to control a size of the airbag to be deployed, according to a position to which the movable member is moved.

An instrument panel assembly includes an instrument panel. The instrument panel assembly includes an airbag having an inboard chamber and an outboard chamber. A panel separates the inboard chamber and the outboard chamber. A diffuser is in fluid communication with both the inboard chamber and the outboard chamber. A releasable vent is between the diffuser and one of the inboard chamber and the outboard chamber. An inflator is in fluid communication with the diffuser.
