An airbag assembly is configured for mounting above an occupant in a vehicle. The example airbag assembly includes an airbag housing that is configured to enclose an airbag cushion when the airbag cushion is in an uninflated state. The airbag cushion is connected to the airbag housing and is configured to project outward from the airbag housing when the airbag cushion inflates from the uninflated state to an inflated state. The example airbag assembly also includes a tether connected at a first attachment point and connected to the airbag cushion at a second attachment point. The first attachment point is located horizontally closer to the occupant than the second attachment point when the airbag cushion is in the inflated state such that the tether limits movement of the airbag cushion in a direction away from the occupant.

The present disclosure relates to a vehicle airbag device, which includes a main cushion and an auxiliary cushion deploying from the main cushion and may more effectively protect both a passenger-seat passenger in a normal seating state and a passenger-seat passenger in a relaxed seating state even in the event of an oblique offset collision by differentiating the deployment of the auxiliary cushion by releasing or maintaining the connection of a tether connected to the auxiliary cushion during deployment of an airbag cushion.

An airbag device for a car may include an inflator positioned between first and second seats and generating an operating gas, a chamber part receiving the operating gas generated by the inflator and expanding between the first and second seats, a tether part connected to the chamber part to control a deployment shape of the chamber part, and a locking release part connected to the tether part at an inner surface or side surface of the chamber part which removes the connection to the tether part according to a control signal.

An airbag assembly includes a base member and an airbag supported by the base member and being inflatable to an inflated position. The airbag includes a panel and a plurality of sheets attached to the panel. The panel includes a first portion extending in a first direction from the base member to a distal end and a second portion extending in a second direction transverse to the first direction from the base member to a distal end. Each sheet is elongated in the first direction along the first portion of the panel and elongated in the second direction along the second portion of the panel. During a vehicle impact, the momentum of the occupant may move the occupant towards the airbag. The airbag may absorb energy from the head and knees of the occupant, which may assist in reducing injuries.

A roof airbag apparatus may include: a cushion having an inlet through which gas discharged from an inflator is introduced; a plurality of tethers connected to the cushion, and arranged along the edge of the cushion so as to be separated from each other; a plurality of steel tabs each having a connection hole formed therein; and a tether guide installed in a pillar shape through the connection holes, and supporting the cushion. The tethers may be connected to the cushion through the respective connection holes

A side airbag device includes: an inflator; a cushion main body that is disposed at a side of a seat of a vehicle and that is expandable from the side toward a front of the vehicle by a gas; a cushion protrusion that is disposed at a vehicle front side with respect to the cushion main body and that is expandable to project further toward the front of the vehicle by receiving the gas from the cushion main body; a tether that is string-shaped, the tether bridging from the cushion protrusion over a predetermined position of the side of the seat, the tether maintaining the cushion protrusion in a state in which the cushion protrusion is folded back toward a rear of the vehicle; a sensor that receives information from the vehicle; and a tether cutter that cuts the tether according to the information obtained by the sensor.

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 curtain airbag system of a vehicle is configured such that a position of an auxiliary chamber provided in a curtain airbag is changed to correspond to an occupant's seating posture or the occupant's lying posture in response to a vehicle collision, so that the occupant is safely protected in various seating postures.

Airbag assemblies including a housing assembly to be mounted above a vehicle occupant position, an inflator, and an inflatable cushion are provided. The inflatable cushion can include first and second lateral chambers and a frontal chamber disposed between the first and second lateral chambers. Airbag assemblies including a first inflatable cushion that is configured to deploy at a first lateral side and forward of a vehicle occupant position and a second inflatable cushion that is configured to deploy at a second lateral side and forward of the vehicle occupant position are also provided.

An assembly includes a first seat and a second seat spaced from the first seat. The assembly includes a first airbag inflatable between the first seat and the second seat from an uninflated position to an inflated position and a second airbag inflatable between the first seat and the second seat from an uninflated position to an inflated position. The first airbag is supported by the first seat in the uninflated position and the inflated position. The second airbag is supported by the second seat in the uninflated position and the inflated position. The second airbag includes a distal end spaced from the second seat in a seat-forward direction. A pyrotechnic retractor is supported by the second seat. The pyrotechnic retractor is operatively coupled to the distal end of the second airbag to move the distal end of the second airbag toward the first airbag.
