Abstract: An airbag assembly can include a side curtain airbag having an inflatable curtain portion and an inflatable sail portion, and a first fold of the sail portion with respect to the curtain portion prior to folding the side curtain airbag into a stowed condition for installation in the vehicle. The curtain portion is disposed rearward of the first fold and the sail portion is disposed at least partially forward of the first fold. A tether has a first end attached to the side curtain airbag rearward of the first fold and a second end attachable to a structural pillar of the vehicle for guiding a direction of expansion of the sail portion during inflation.

Abstract: An inflatable side airbag restraint for use in passenger vehicles. The airbag includes a relief portion providing clearance for the arm and elbow of an occupant or test device which reduces or eliminates lateral compression of the arm on the chest and abdomen regions of an occupant or test device.

Abstract: A side curtain airbag to be deployed downward along an inner side surface of a passenger compartment of a vehicle can include at least one expandible chamber having an inflatable curtain portion and an inflatable sail portion extending forwardly from a foremost anchor point of the curtain portion with respect to the vehicle, and a tether attached to the expandible chamber at one end and attachable to a structural pillar of the vehicle at an opposite end for guiding a direction of expansion of the sail portion during inflation. A method for folding a side curtain airbag can include forming an expandible chamber from an inflatable curtain portion and an inflatable sail portion, positioning the sail portion to be overlying the inboard side of the curtain portion with a Z-shaped fold portion, and locating the inboard side of the chamber facing inboard when in a stowed position.
