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.

There is provided an occupant protection device for protecting an occupant seated on a seat, including: an airbag folded and accommodated in a bag shape made of a flexible sheet material; and a holding belt portion that is wrapped around a hip of the occupant and holds the folded airbag. The airbag is configured to, when the airbag is activated, allow an inflation gas to flow thereinto, and inflate to protrude forward and upward from the holding belt portion, and includes an upper body restraining surface capable of restraining an upper body of the occupant, on a rear surface side, when inflation is completed, and a vehicle body side member abutting surface that abuts against a vehicle body side member provided in front of the seat to be capable of ensuring a reaction force of the airbag when the occupant is restrained, on a front surface side.

The present disclosure relates to a leg protection device for an occupant protection system of a vehicle. The leg protection device includes an airbag module. The airbag module includes an airbag and a gas generator that inflates the airbag to a deployed state such that the airbag is disposed in the footwell and in front of a vehicle seat. The airbag includes a first chamber and a second chamber fluidically connected to the first chamber. The first chamber and the second chamber are deployed in the footwell to protect an occupant when the airbag is set in the deployed state. The first chamber is connected to the second chamber by a flexible connection region that diverts the airbag along the object in any spatial direction when the airbag encounters the object during deployment in the footwell.

An apparatus for helping to protect an occupant of a vehicle includes an airbag configured to be mounted to a support structure of the vehicle. The airbag is inflatable to deploy from a stored condition away from the support structure toward a vehicle seat in which the occupant is seated 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.

A knee airbag device includes: an airbag case disposed at a lower face part of an instrument panel; a knee airbag accommodated within the airbag case in a folded state, the knee airbag inflating and deploying toward a vehicle rear side and a vehicle upper side upon being supplied with gas; and an airbag door part disposed at a vehicle lower side of the airbag case, the airbag door part having a substantially U-shaped rupture target part, the rupture target part is open toward a vehicle front side as seen in a plan view, at a portion, of a bottom wall part configuring a vehicle lower side face of the airbag door part, disposed rearward of an intermediate part of the airbag door part in a vehicle front-rear direction, and the portion of the bottom wall part disposed rearward of the intermediate part opening toward a vehicle lower side upon rupture of the rupture target part caused by inflation pressure of the knee airbag.

An assembly includes a steering wheel having a hub rotatable about a rotational axis and a rim spaced radially from the hub. The assembly includes a first airbag supported by the hub and inflatable from an uninflated position to an inflated position. The assembly includes a second airbag inflatable from an uninflated position to an inflated position. The second airbag extending annularly around the rotational axis. The first airbag and the second airbag being spaced from each other along the rotational axis when the first airbag and the second airbag are in the uninflated position. The rim being between the first airbag and the second airbag when the first airbag and the second airbag are in the inflated position.

A vehicle airbag control system has an airbag module, a detector and an electronic controller. The airbag module has an airbag that is configured to be positioned below a vehicle floor panel in an undeployed state. The airbag that is configured to be positioned to be above the vehicle floor panel in the deployed state. The detector is configured to detect a presence of an obstruction over the airbag module at a location above the vehicle floor panel. The electronic controller is programmed to deploy the airbag based on a detected result of the detector.

A rear-seat airbag is configured to expand and deploy from a lower portion of a center console of a vehicle toward a center portion of a row of rear seats. A point of intersection of virtual loci of forward movements of a head, a chest, and knees of a passenger sitting in the center portion of the row of rear seats in response to an impact generated by a collision of the vehicle coincides with a center of gravity of the rear-seat airbag when the rear-seat airbag expands and deploys.

A rear-seat airbag configured to expand and deploy inward of a vehicle from a door trim beside a rear seat includes a first expansion air chamber and a second expansion air chamber. The first expansion air chamber is configured to expand and deploy to a space facing leg parts of a passenger in the rear seat that are above knees of the passenger. The second expansion air chamber is configured to expand and deploy to a space between the first expansion air chamber and the passenger in the rear seat.

A knee air bag reduces an injury to occupant's legs by employing a slim crash pad design. The air bag includes a first cushion that is deployed from an inner side of a crash pad toward an occupant to fill a space below the crash pad and a second cushion that is deployed between the first cushion and the occupant to support occupant's legs while being supported on the first cushion.
