A curtain airbag for a vehicle may include a curtain airbag cushion; a venting chamber that fills a space between an end portion of a frontal airbag on the door window side and an A pillar; and a first vent opening formed in a portion of the venting chamber, the portion being near the door window.

Holding elements for attaching an element of an airbag assembly to a holding unit comprising such a holding element and an inflating element, along with related methods. In some embodiments, the holding element may be configured for attaching an element of an airbag assembly via at least one tear seam, and the holding element may comprise a first side wall made of a flexible material and a second side wall made of a flexible material. A peripheral connection may couple the first side wall and the second side wall and may extend from a first end to a second end such that the first side wall, the second side wall, and the peripheral connection define a space therebetween and an opening. The holding element may further comprise an inlay comprising a hole and having at least one layer being located between the first side wall and the second side wall.

Airbag cushion assemblies for aspirating ambient air to enhance inflation. Some embodiments may comprise an inflation module comprising an inflator and a plurality of high-velocity nozzles fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into an airbag cushion. A housing coupled to the airbag cushion, may comprise an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion. The plurality of high-velocity nozzles may be configured to, upon actuation of the inflator, draw ambient air into the airbag cushion along with the inflation gas from the inflator. In some embodiments, a valve assembly may be provided that is configured to open upon actuation of the inflator and to close following inflation of the airbag cushion to prevent air and inflation gas from exiting through the aspiration inlet.

A restraint system includes a side air curtain, a sail panel, and a secondary cushion. The side air curtain is inflatable to an inflated position and has a top edge, a bottom edge, and a forward edge extending from the top edge to the bottom edge. The sail panel extends from the forward edge. The secondary cushion is inflatable to an inflated position and is elongated in a direction away from the bottom edge and the forward edge toward the top edge.

An airbag apparatus including: a first chamber connected to an inflator; a second chamber connected to the rear of the first chamber and supported by the first chamber, supporting the head of a passenger in case of an oblique collision of a vehicle, and having a first passage through which gas of the first chamber is introduced; a third chamber connected to the rear of the first chamber and supported by the first chamber, disposed at one side of the second chamber, and supporting the head of the passenger in a head-on collision of the vehicle; a connection tether connecting the second and third chambers to limit separation between the second and third chambers; and a shut-off valve closing the first passage to block gas of the second chamber from being discharged to the first chamber through the first passage, when the first chamber is completely deployed.

Disclosed is an airbag apparatus for a vehicle. The disclosed airbag apparatus for a vehicle includes a main cushion part configured to support a passenger's body by being deployed, a vent hole part formed in the main cushion part and configured to pass gas, a tube part coupled to the main cushion part and configured to guide a movement of the gas passed through the vent hole part, and a sub-cushion part coupled to the main cushion part, formed to surround the tube part, and configured to support the head of the passenger at the time of deployment.

An airbag includes an internal pressure adjusting mechanism: including: a tether arranged in a bag part; a long side part; and a short side part; and adjusting an exhaust of the inflation gas: to be in an exhaust mode in which the exhaust is facilitated when the tether is loosened; and to be in an exhaust suppression mode in which the exhaust is suppressed when the tether is stretched. In a state where the tether is loosened during the exhaust mode, facing edge parts of the long side part and the short side part are separable. In a state where the tether is stretched during the exhaust suppression mode, the facing edge part of the long side part and a root side part are inflated around the short side part and a leading edge side part contacts a back surface side of the short side part.

An airbag venting device (10) comprises a housing (24) which includes a first flow orifice (18) facing away from the airbag (12) and a second flow orifice (20) facing the airbag (12). The housing (24) has an axial total length (26), the first flow orifice (18) has a first axial opening length (34) and the second flow orifice (20) has a second axial opening length (34). An adjustable closure element (22) assigned to the housing (24), in an open position, releases at least one of the two flow orifices (18, 20). An actuator device (30) interacts with the closure element (22) to release and/or to close the flow orifice (18, 20), and, in doing so, the axial total length (26) of the housing (24) is less than 3 times the length of the longer axial opening length (34) of the two flow orifices (18, 20).

The present invention discloses an airbag apparatus for mobility that safely protects passengers even if an impact comes from different directions in collisions such as a front collision, a side collision, and an oblique collision as the airbags inflate to surround the passengers in the event of a collision.

A side airbag device for a motor vehicle includes an airbag, in which, in the event of an impact, gas is introduced by a gas generator of the side airbag device. The airbag includes drain valve for removing the gas immediately after the impact. The device also includes an electronic computing unit and a further drain valve and/or a further gas generator. A passenger of the motor vehicle is detected by a detection unit. The device is filled with the gas in the event of the impact to protect this passenger. The electronic computing unit is configured, depending on the detected passenger, to determine a gas pressure in the airbag by actuation of the further drain valve or the further gas generator before the impact and to adapt the gas pressure to the passengers during the impact.
