Abstract: A curtain airbag is configured to include a sub chamber to simplify a structure of the curtain airbag and to improve deployment performance of an airbag cushion. The curtain airbag includes a main chamber of the airbag cushion fixed to an upper end inside a vehicle body and configured to be deployed downward, the sub chamber of the airbag cushion configured to be deployed from an upper portion of a pillar trim located inside the vehicle body and to allow the main chamber to move toward a central region of a vehicle, and a cushion cover configured to cover the main chamber and the sub chamber while being folded, wherein the sub chamber is folded with an upper end thereof located higher than a folding center of the main chamber.

Abstract: A side airbag may include: a bracket coupled to a side portion of a seat; a housing to which the bracket is coupled along the edge thereof through insert molding, and which has an internal housing space communicating with the outside through an opening formed on one side thereof; a cover formed as one body with the housing so as to close the opening, and having a tear line formed along the edge thereof; and a cushion housed in the housing space, and deployed to the outside through the opening by an inflation force while tearing the tear line, when gas is supplied thereto.

Abstract: Disclosed herein is a method of folding a far-side airbag, which includes forming a first folding part in such a manner that an upper side of an airbag seat is folded inboard, forming a second folding part by folding both widthwise sides of the airbag seat, forming a third folding part by folding the upper side of the airbag seat, forming a roll-folding part by roll-folding the upper side of the airbag seat, forming an overlapping part by folding over an inflator of the airbag seat, and folding the roll-folding part so that the roll-folding part overlaps the overlapping part.

Abstract: Disclosed herein is a hard cover for a side airbag. The hard cover includes a housing accommodating a cushion, a cover unit covering an opening of the housing and having a cut part formed to be cut when the cushion is deployed, a hinge connecting the cover unit and a rear of the housing, a first restraint unit provided on a front of the housing, a first hook unit provided on a front of the cover unit to be caught and restrained by the first restraint unit, a second restraint unit provided on each of upper and lower sides of the housing, and a second hook unit provided on each of upper and lower sides of the cover unit to be caught and restrained by the second restraint unit and separated from the second restraint unit when the cushion is deployed.

Abstract: A folding method of a far-side airbag apparatus may include: a first folding step of folding an upper portion of an airbag sheet toward an inboard side; a second folding step of folding both widthwise sides of the airbag sheet toward an outboard side; a third folding step of folding the upper portion of the airbag sheet toward the inboard side; and a fourth folding step of roll-folding the airbag sheet.

Abstract: A side airbag apparatus may include: a housing coupled to a seat and having a cover to open/close an opening; a first cushion housed in the housing, unfolded and deployed to the side by gas supplied from an inflator so as to open the cover, and formed by folding an airbag sheet; and a second cushion connected to the first cushion, wound toward the seat and housed in the housing, unwound and deployed to the outside through the opening when the first cushion is deployed, and formed by winding the airbag sheet.

Abstract: The disclosure relates to a side airbag device including: an inflator that discharges gas; a cushion that covers the inflator and is expanded toward a side of a passenger by the gas discharged from the inflator; and a tether that is disposed through and around the cushion and induces an upper portion of the cushion to bend when the cushion expands, thereby being able to prevent a passenger-to-passenger collision and protect even one passenger.
