Abstract: A curtain airbag device with which the position of a tether that pulls an end chamber during inflation and deployment thereof can be stabilized, thereby stabilizing the deployment behavior of the end chamber. A curtain airbag device 100 is housed in a side face upper portion of a vehicle cabin and inflated and deployed along the side face, and includes a main chamber 132 that is inflated and deployed using gas from an inflator 122, an end chamber 134 that is disposed on a front end 136 of the main chamber and inflated and deployed by gas received from the main chamber, a tab 144 attached to an upper portion of the main chamber, a bracket 128 fixed to the side face upper portion of the vehicle cabin, the tab being passed through the bracket, and a tether 126 attached so as to extend from a front end 138 of an upper portion of the end chamber to the bracket, wherein a length La of the tether is shorter than a distance Lb from the front end of the upper portion of the end chamber to the bracket in a case where the main chamber and the end chamber are inflated and deployed without the tether.

Abstract: A curtain airbag device that allows easy recognition and correction of twisting of an airbag during attaching. The curtain airbag device can be stored in a compact manner during transportation. The curtain airbag device including an airbag that is disposed along a roof side rail of a vehicle interior, and that can deploy so as to cover a window portion on a side face of the vehicle interior, the curtain airbag device further including a cover that covers the airbag, at least, in a part of the folded or rolled airbag in the longitudinal direction. The cover is formed of a pliable fabric material of polymer fibers, and maintains the shape of the rolled-up airbag through mutual fusion of at least a part of the polymer fibers. A high stiffness portion harder than other portions and formed during the fusion of the cover is provided in the cover extending in the longitudinal direction of the cover.

Abstract: A cover member (18) is formed of a pliable fabric material having a plurality of polymer fibers, and is configured to maintain the shape of the airbag by mutual fusion of at least part of the polymer fibers. The cover member (18) is configured to have a high stiffness portion (25) of higher stiffness than other portions of the cover member, as a result of partial overlaying of the pliable fabric material in more folds than at other portions.
