The present invention is provided with an inflator arranged on the occupant side of the side frame positioned on the side portion inside the seatback that generates expansion gas and an airbag that is expanded by the expansion gas and protects an occupant seated on the vehicle seat. The airbag includes a main chamber that deploys toward the front of the seatback, and a pre-chamber that houses the inflator inside and is connected to the occupant side of the main chamber. In addition, an internal tether having a front end part connected to the front portion of the pre-chamber and a rear end part connected to the rear portion of the pre-chamber are provided inside the pre-chamber.

The present invention provides a seat airbag device for a vehicle, the seat airbag device including an airbag cushion including a lateral chamber positioned at lateral sides of a passenger and configured to be deployed forward from a seatback of a vehicle, a front chamber configured to be deployed forward from an upper side of the seatback to surround the passenger, and an auxiliary chamber configured to be deployed from the front chamber toward a front side of the passenger so as to be positioned between the front chamber and the passenger, and a support tether extending from the seatback and connected to the airbag cushion to support the airbag cushion.

An assembly for a vehicle includes a first seat and a second seat. The assembly includes a crossbar positioned between the first seat and the second seat. The assembly includes an airbag supported by the crossbar. The assembly includes a controller programmed to position the crossbar in a raised position in response to a detected occupant egress.

In one aspect, an apparatus for helping to protect an occupant of a vehicle includes a frontal curtain airbag. The airbag has overlying panels that are interconnected. The airbag is deployable a deployed condition in which the airbag spans across a width of a windshield opening of the vehicle. A restraining panel is separate from and extends widthwise over the panels of the airbag. The restraining panel is connected to the airbag and has a width configured to cause opposing end portions of the deployed airbag to be bent toward one another and into a curved configuration. Pressurization in the deploying airbag tensions the restraining panel widthwise. The tensioned restraining panel maintains the bend in the deploying airbag so that an effective airbag depth is measured between the restraining panel and the airbag.

An airbag includes a U-shaped chamber, a head-impact chamber, and an uninflatable panel. The U-shaped chamber has a first side leg, a second side leg, and a top extending from the first side leg to the second side leg. The head-impact chamber is disposed between the first side leg and the second side leg. The uninflatable panel extends from the first leg to the second leg adjacent the head-impact chamber.

An airbag includes a main inflation portion to be deployed and inflated at an outer side of the upper body of an occupant, and an auxiliary inflation portion disposed at a position adjacent to an inner side of the main inflation portion and to be deployed and inflated at an obliquely front outer side of a head portion. In the airbag whose deployment and inflation are completed, a maximum dimension in a facing direction in which an outer main body portion and an inner main body portion of the auxiliary inflation portion face each other is smaller than a dimension in a direction orthogonal to the facing direction. The auxiliary inflation portion has the outer main body portion as a joining area, and is joined to the main inflation portion in the joining area, in a state of being in communication with the main inflation portion.

A side airbag that is configured to reduce risk of injury to a passenger by differentiating inner pressures in an airbag cushion at the beginning of a deployment of the airbag cushion. The side airbag includes a diffuser configured to supply gas discharged from an inflator to an inside of an airbag cushion, a separator partitioning an internal space of the airbag cushion up and down so that an upper region of the airbag cushion is more rapidly inflated than a lower region of the airbag cushion by the gas introduced into the airbag cushion through the diffuser, and a passage formed between the upper region and the lower region such that the gas flows between the upper region and the lower region.

A center airbag apparatus may include: an inflator mounted in an instrument panel and configured to inject gas; a first cushion part deployed by the gas injected from the inflator, and configured to support a driver airbag; and a second cushion part connected to the first cushion part, and configured to be deployed between the driver airbag and a passenger airbag to protrude toward the rear of a vehicle based on the driver airbag.

Disclosed is an airbag apparatus for a vehicle. The disclosed airbag apparatus for a vehicle includes a main cushion part configured to support a passenger's body by being deployed, a vent hole part formed in the main cushion part and configured to pass gas, a tube part coupled to the main cushion part and configured to guide a movement of the gas passed through the vent hole part, and a sub-cushion part coupled to the main cushion part, formed to surround the tube part, and configured to support the head of the passenger at the time of deployment.

An assembly for a vehicle includes a dash. The assembly includes an airbag supported by the dash and being inflatable to an inflated position. The airbag includes a knee chamber, a chest chamber supported by the knee chamber in the inflated position, and a head chamber supported by the chest chamber in the inflated position. The chest chamber is connected to the knee chamber at a lower seam that defines a lower fluid pathway. The head chamber is connected to the chest chamber at an upper seam that defines an upper fluid pathway. The assembly includes an inflator supported by the dash and being connected directly to the knee chamber.
