A vehicle side curtain airbag device having front protection function, comprising a side airbag (1) and an auxiliary airbag (2) connected to one side surface of the side airbag (1) and arranged in a left/right transverse direction after being expanded; a dividing hole membrane (3) is disposed between the side airbag (1) and the auxiliary airbag (2); the dividing hole membrane (3) is ensured to be opened only when the internal pressure of the side airbag (1) reaches a certain value, thus realizing self-adaptive opening threshold adjustment, controlling the instant of inflation and inflation speed of the auxiliary airbag (2), and adjusting the stiffness of the auxiliary airbag (2). When a vehicle has a collision, the device protects the head and neck of a passenger in both side collision and front collision traffic accidents, thus effectively absorbing the collision impact energy of the passenger, and reducing injury to the passenger.

Airbag cushion diffusers comprising one or more frangible portions and related airbag cushion assemblies and methods. In some embodiments, an airbag cushion assembly may comprise an airbag cushion having an internal diffuser positioned therein. The internal diffuser may comprise a lower panel that may be sewn or otherwise directly coupled to the airbag cushion and an upper panel coupled to the lower panel about respective entire peripheries of the upper and lower panels so as to define a diffuser chamber between the upper panel and the lower panel. The upper panel may comprise a plurality of openings for delivery of inflation gas therethrough and may comprise one or more openings, slits, and/or weakened regions configured to facilitate tearing in specific locations of the diffuser.

A roof airbag apparatus may include: a cushion configured to cover a roof when deployed; a pair of guides having a length in the deployment direction of the cushion, and configured to guide both sides of the cushion in the deployment direction; and a deployment resistance reducer having a connector connected to one end of each of the guides so as to apply an elastic force from a first location toward the rear, wherein the connector is moved to a second location in a front of the first location by frictional resistance which is applied to the guide when the cushion is deployed.

An airbag includes plural bag portions respectively including two sheet members attached to each other, and a welded portion at which the sheet members being in contact with each other are attached to each other. The welded portion includes a communication hole penetrating the sheet members to communicate the bag portions, and a rib portion arranged radially outward of the communication hole, the rib portion protruding in the thickness direction from a welded surface of the welded portion. The rib portion includes an annular rib surrounding the communication hole, and a cutout portion provided at the annular rib. The rib portion includes plural radial ribs arranged radially inward of the annular rib, the plural radial ribs radially surrounding the communication hole and extending in a radial direction of the communication hole. At least one of the radial ribs is arranged at a position radially away from the communication hole.
