A variable control apparatus for an airbag of a vehicle includes: a plurality of tethers each of which having one side coupled to a front sheath among a plurality of sheaths of an airbag cushion, each of the plurality of tethers formed to have a length shorter than a distance between the front sheath and a rear sheath when the airbag cushion is fully deployed; a release mechanism provided at a rear sheath side of the airbag cushion, connected to the respective other sides of the plurality of tethers, and selectively releasing a tether among the plurality of tethers upon an operation of the release mechanism; and a controller configured to variably control a deployment shape of the airbag cushion by operating the release mechanism based on a collision direction of the vehicle, a seat state of a seat of the vehicle, or a sitting posture of a passenger in the vehicle.

A vehicle configuration wherein the center of mass of the vehicle is approximately superimposed upon the passenger and driver centers of mass when seated within the vehicle. An occupant's center of mass can be approximated using a standard center of mass position approximation, or a combination of any number of standard center of mass position approximations. The vehicle's center of mass can be approximately superimposed upon the occupant's center of mass in at least the longitudinal and vertical directions.

An airbag device includes: an airbag body that is configured to deploy toward a front side of a driver; and a control unit that is configured to deploy the airbag body using a first deployment method when a central axis of a rim portion of a steering member of a vehicle is in a first state and a deployment condition is satisfied and deploy the airbag body using a second deployment method in a second state when an inclination angle of the central axis in relation to the central axis in the first state exceeds a threshold and the deployment condition is satisfied.

Various embodiments of vehicle occupant safety systems having extendable restraints for use with, for example, airbags are described herein. In one embodiment, for example, the disclosed technology includes a 2-point occupant restraint that secures an occupant in an aircraft seat. In this embodiment, the aircraft seat is positioned in a seating area that includes a forward monument housing a stowed airbag. In the event of a crash or other significant dynamic event that causes, for example, a rapid deceleration of the aircraft above a preset magnitude, the airbag deploys between the occupant and the monument as the dynamic forces cause the occupant to pitch forward. The forward momentum of the occupant's body creates a significant tension load in the 2-point restraint, which causes the restraint to extend by a preset amount, thereby allowing the occupant to move forward in the seat more than the occupant would have moved had the occupant been wearing a conventional, non-extending 2-point restraint. Although the occupant is allowed to move forward, the occupant remains secured to the extended restraint by means of non-extending webbing that is secured around the waist of the occupant. Allowing the occupant to move forward in this manner enables the occupant's upper torso to impact the airbag at a reduced or otherwise more favorable angle. This can reduce both the speed and the angle at which the occupant's head impacts the airbag, thereby reducing the likelihood of injury.

A vehicle includes a floor, a roof, and a pair of body sides spaced from each other. A pillar is spaced from both of the body sides. The pillar has a first end at the roof and a second end at the floor. An airbag is supported on the pillar.

A side airbag device 100 includes: a main bag 120, is built in a seat of a vehicle, and inflates and deploys toward a side of an occupant and a vehicle front side; an inner bag 122 which is formed in a bag shape independent of the main bag 120, and inflates and deploys on a vehicle rear side inside the main bag 120. An inflator 110 provided inside the inner bag 122 to supply gas; and a tension member 126 which spans between the vehicle front side and the vehicle rear side inside the inner bag 122 and is tensioned as the inner bag 122 inflates and deploys. The length of the inner bag 122 in the front-back direction of the vehicle at inflation is restricted by the tension member 126 to a predetermined range, and the inner bag therefore inflates in a vehicle width direction and pushes and spreads the vehicle rear side of the main bag 120 from the inside of the main bag 120 to both sides in the vehicle width direction.

An assembly includes a seatback. The assembly includes a first airbag and a second airbag, each inflatable to an inflated position spaced from each other at the seatback and abutting each other in front of and spaced from the seatback. The assembly includes a sheet extending from the first airbag to the second airbag in front of where the first airbag abuts the second airbag in the inflated positions.

A seat device for a vehicle includes a seat for supporting a lower body of a vehicle occupant, and a backrest for supporting an upper body of the occupant. The seat device further includes an arresting portion that is stored in a storage position disposed in the seat. The arresting portion is configured to be deployed from the storage position and restrain a part of the lower body of the occupant from moving forward in the event of a collision of the vehicle.

A vehicle seat includes a seat back having a front surface and a rear surface, a panel movable along the rear surface from a stowed position adjacent the rear surface to a deployed position facing the front surface, and an airbag supported on the panel and inflatable toward the front surface to an inflated position in which the airbag contacts the panel.

The present disclosure provides an airbag for a vehicle. The airbag safely supports a passenger after deploying forward from behind a passenger in a seat. Additionally, the airbag is able to be changed in position to safely protect a passenger by changing the position even when the position of a seat is changed.
