An airbag device includes an airbag formed with a discharge portion. The discharge portion includes: an opening portion; a tack portion around the opening portion; and a regulating belt portion disposed on a peripheral edge of the opening portion to regulate opening and closing of the opening portion. When the inflation of the airbag is completed, the tack portion is maintained in a folded state by the regulating belt portion due to tension acting on the regulation belt portion, so that a closed state of the opening portion is capable of being maintained, and when the tension does not act on the regulating belt portion, the folded state is released and the opening portion is brought into an open state.

An airbag control device for controlling the volume of an airbag (10) of a restraining means, comprising an inflator (14) for inflating the airbag (10) and an electrically controllable decoupling device (22) for tension means via which the geometry of the airbag (10) can be varied, is characterized in that the inflator (14) and the decoupling device (22) are fluid-communicated and the decoupling device (22) includes at least one outlet opening (36) the cross-section of which is variable by an electrically controllable actuator (46) and through which gas can escape from the inflator (14) to the atmosphere. Moreover, the invention describes an airbag unit.

An airbag comprises an airbag panel defining an inflatable volume. A discharge port having a closure is formed in the airbag panel. A tether extends through the inflatable volume from a first end tightly connected to the airbag panel in the direction of the discharge port to an opposite second end. The discharge port closure is connected to the second tether end and the airbag panel. The tether at least in portions has a two-ply design and includes two strap layers. A control strap extends transversely to the tether through the inflatable airbag volume. A first control strap portion is fastened to the airbag panel and to the first strap layer. A second control strap portion is fastened to the airbag panel and to the second strap layer.

A one-way multiple cushions and chambers vehicle airbag assembly includes an airbag body having a primary airbag chamber and a secondary airbag chamber. At least one one-way vent valve provides a gas interconnection passage between the primary airbag chamber and the secondary airbag chamber.

In a vehicle occupant protection system, a first tether is permanently fastened to a front panel of the airbag and is detachably fixed to an actuator unit on the module side. A second tether is arranged on the module side and is connected to the first tether, wherein in an extension of the second tether there is provided a decoupling arrangement which is located between the second tether and the first tether only when the actuator unit is activated.

An airbag cushion and an airbag apparatus for a passenger seat including the same. A side panel portion of the airbag cushion is divided into a first panel portion, which is disposed at an upper position, and a second panel portion, which is disposed at a lower position, an open gap communicating with the outside is formed in an overlap region between the first panel portion and the second panel portion, and a low-risk deployment (LRD) vent for the airbag cushion is formed using the open gap. Accordingly, the configuration for forming the LRD vent is simplified.

An airbag device configured to improving the opening and closing operability of a vent hole to reduce injuries to a passenger. The airbag device includes a cushion panel of an airbag cushion, the cushion panel having a hole, a guide panel overlapped with the cushion panel, and having a hole matching with the hole of the cushion panel, a bellows vent having a hollow vent hole therein, and connected to the hole of the cushion panel and the hole of the guide panel in a folded state while being located therebetween, and a tether connected to the bellows vent, and configured to close the vent hole by the bellows vent unfolded between the cushion panel and the guide panel as a tension pulling the bellows vent in a deployment direction of the airbag cushion due to an expansion pressure of the airbag cushion is generated.

An in-seat airbag device having an airbag main body including: an outer side airbag portion having a front-rear chamber that expands past one side of a head of a passenger toward a seat front side, a left-right chamber that expands from a seat front side end portion of the front-rear chamber toward a seat width direction inner side and is disposed at a seat front side of a face of the passenger, a distal end chamber that expands from a seat width direction inner side end portion of the left-right chamber toward a seat rear side and is disposed at another side of the head of the passenger, and a tether that joins the front-rear chamber and the distal end chamber; and an inner side airbag portion that expands and is disposed between the front-rear chamber, the left-right chamber and the distal end chamber.

The airbag device includes a first airbag cushion part and a second airbag cushion part installed on each side of a seat of a vehicle, a first active vent provided in the first airbag cushion part and a second active vent provided in the second airbag cushion part, and a controller that controls the first active vent or the second active vent to open and the other to close when the first airbag cushion part and the second airbag cushion part are expanded and deployed.

The airbag comprises an outer skin (20) having a first opening (26), a flap (32) being at least indirectly attached to the outer skin (20), and a tether (37). The first end of the tether is attached to a flap (32) and the second end (37b) of the tether is detachably attached to a holding element (16). When the airbag is deployed and the tether (37) is under tension, the flap (32) covers the first opening (26) at least partially such that the ventilation device is in a closed or throttled first state. When the airbag is deployed and the tether (37) is not under tension because the second end (37b) of the tether is detached from the holding element, the flap (32) covers the first opening (26) less than in in the first state, such that the ventilation device is in second state. The flap (32) is located between the outer skin (20) and an additional layer (34) having a second opening (36) at least partially overlapping the first opening (26).
