An assembly includes a vehicle seat. The assembly includes an airbag supported by the vehicle seat and inflatable to an inflated position. The airbag includes a main chamber, a first side chamber, and second side chamber spaced downwardly from the first side chamber. The assembly includes a computer including a processor and a memory storing instructions executable by the processor to determine a size of an occupant seated in the vehicle seat and, based on the size of the occupant, selectively inflate one of the first side chamber from an uninflated position to an inflated position or the second side chamber from an uninflated position to an inflated position.

An occupant protection system may comprise an expandable curtain, expandable bladder and tether. The curtain may be configured to expand from a stowed state to a deployed state. In the deployed state, the curtain may comprise a transverse portion having a support side face and a rear side face. The bladder may be configured to expand from a stowed state to a deployed, wherein in the deployed state, the bladder comprises an occupant facing surface and a rear surface configured to face the support side face of the curtain. The tether may be attached at a first location to the bladder and at a second location such that in the deployed state of the curtain and bladder, the tether extends behind the rear side face of the curtain and frictionally engages the rear side face of the curtain, thereby creating a resistance to lateral movement of the bladder.

A side airbag device is to be attached to a side portion of a seat back and includes an inflator and a bag-shaped airbag. The airbag includes a first inflation part at which a gas ejection hole of the inflator is disposed and configured to be inflated and deployed beside a body of an occupant, and a second inflation part communicating with the first inflation part and configured to be inflated and deployed beside a head of the occupant. A portion of the first inflation part is configured to be inflated and deployed above a console box and to come into contact with an upper surface of the console box. In a state where the airbag is folded, the second inflation part is folded to overlap the first inflation part such that the second inflation part is arranged inward of the first inflation part in a vehicle width direction.

A vehicle includes a vehicle body defining an interior cabin. The interior cabin includes a passenger compartment and a cargo compartment. The vehicle body includes a floor below the interior cabin. An airbag is supported on the floor and is inflatable upwardly from the floor between the passenger compartment and the cargo compartment. A retractor is fixed to the vehicle body above the airbag. A tether extends from the retractor to the airbag.

The present invention is a side airbag device housed in the side support part of a vehicle seat and includes an airbag for restraining an occupant and an inflator. The airbag includes a first bag housing the inflator which is capable of inflating and deploying, and a second bag capable of inflating and deploying on the side of the first bag. The second bag is configured to be deployed by inflation gas flowing in from the first bag. At the upper edge of the second bag, an inclined part is formed that is inclined to be lower at the front thereof than at the rear thereof when viewed from the vehicle width direction. The front portion of the inclined part is configured to be located lower than the center line extending in the longitudinal direction of the upper arm of the occupant seated in a vehicle seat.

A roof airbag for a vehicle is proposed. The roof airbag for a vehicle has an airbag cushion configured to be unfolded downward from an inner roof to protect a passenger seated on a seat, and the airbag cushion has a shape bent toward the passenger by a main tether and a sub-tether, thus securing a restraining force for the passenger and safely protecting the passenger from an impact, and the airbag cushion is unfolded downward while avoiding insertion between a roof-side portion of the roof and a headlining by the sub-tether. Specifically, the airbag cushion is prevented from being transversally contracted and an unfolding shape of the airbag cushion is maintained. Furthermore, the fluidity of a gas flow in the airbag cushion is secured, so that the airbag cushion is rapidly unfolded.

A seat-mounted airbag device includes a guidance member and an airbag body which includes a front-rear chamber and a distal-end chamber and is accommodated in a side portion of a headrest of a window-side vehicle seat in a state where the airbag body includes an outward winding portion. At the time of a front end collision, the front-rear chamber deploys from the side portion through a gap between the head of an occupant sitting on the window-side vehicle seat and the head of an occupant sitting on a central-side vehicle seat and is disposed in the gap. The distal-end chamber deploys inwardly from a front end part of the front-rear chamber. The guidance member projects from the side portion prior to the deployment of the airbag body so as to be disposed between the airbag body and the head of the occupant sitting on the central-side vehicle seat.

An assembly includes a seat having a seatback. The assembly includes an airbag supported by the seatback and inflatable to an inflated position. The airbag extends from the seatback to an end in the inflated position. The assembly includes a spool rotatably supported by the seatback. The assembly includes a belt extending along the airbag in the inflated position. The belt extends from the spool to the end of the airbag. The belt is extendable from the spool.

The present invention provides a roof airbag for a vehicle, the roof airbag including an airbag cushion mounted on a roof panel of a vehicle and configured to deploy downward from the roof panel to a location between front and rear passengers seated while facing one another, a front tether configured to surround an outer portion of the airbag cushion and having one end connected to a front side of the airbag cushion and the other end connected to the airbag cushion, and a rear tether configured to surround the outer portion of the airbag cushion and having one end connected to a rear side of the airbag cushion and the other end connected to the airbag cushion, in which the front and rear tethers surround the outer portion of the airbag cushion while intersecting each other.

A deployable restraint system comprising a reaction panel, a panel actuator that deploys the reaction panel, a cushion, and a cushion actuator that deploys the cushion. When both the reaction panel and the cushion are deployed, the reaction panel is configured to transfer force from the cushion to a roof and only one of two sides of a compartment. A lower end of the reaction panel is configured to couple to the one of the two sides with a tether that is moved by the panel actuator.
