An airbag module includes a curtain-type airbag arranged in a packaged configuration, and a strap looped around the airbag. The airbag includes a mounting edge extending exteriorly along the airbag. The mounting edge includes a securement adaptor projecting therefrom exteriorly to the airbag. The strap includes two endpieces respectively anchored to the mounting edge and secured with the securement adaptor, thereby securing the strap in a loop around the airbag at the mounting edge.

A vehicle occupant protection expandable bladder may comprise an initial expandable chamber, an occupant restraining expandable chamber and a releasable connection that is configured to connect the occupant restraining expandable chamber to the initial expandable chamber or to a vehicle. The vehicle occupant protection expandable bladder may be configured to be expanded from a stowed state to a deployed state in a vehicle. The deployed state may comprise a first phase in which gas flow from the initial expandable chamber to the occupant restraining expandable chamber is at least substantially restricted and a second phase in which gas flow from the initial expandable chamber to the occupant restraining chamber is unrestricted. The releasable connection may be configured to release the connection in the deployed state.

A head portion protection airbag device includes: an airbag, formed into a folded body being folded such that a lower edge side in an unfolded state approaches an upper edge side, wrapped with an unfoldment preventing tape material and attached to the upper edge side of the window, assembled with a twisting restriction member, which is configured to prevent twisting of the folded body, on an upper edge side of the airbag, and attached to the upper edge side of the window as a bag attachment body. A plurality of attachment piece portions, which are attached to a body side of the vehicle, are arranged side by side on the upper edge side of the airbag. The bag attachment body is wrapped with the tape material in a state where the twisting restriction member is assembled to the upper edge side of the airbag in the folded body.

A vehicle safety system includes an actuatable restraint for helping to protect a vehicle occupant and a controller for controlling actuation of the actuatable restraint in response to a vehicle rollover event. The controller is configured to execute a discrimination algorithm comprising at least one classification metric that utilizes at least one of vehicle pitch rate (P_RATE) and vehicle roll acceleration (D_RATE) to discriminate at least one of a ramp rollover event and a soil rollover event from an embankment rollover event. The discrimination algorithm determines a classification of the vehicle rollover event as one of a ramp rollover event, a soil rollover event, and an embankment rollover event. The controller is also configured to select a deployment threshold for deploying the actuatable restraint. The deployment threshold corresponds to the classification of the vehicle rollover event.

A method for manufacturing a one-piece woven (OPW) air bag includes providing yarns having a spin finish and warping the yarns on at least one beam of a loom. The yarns are simultaneously woven into a fabric air bag structure having two layer portions defining an inflatable volume and single layer portions forming seams delimiting the inflatable volume. The air bag structure is coated to cover the spin finish. The coated air bag structure is cut to define the one-piece woven air bag.
