Abstract: PROBLEM
To provide an airbag device capable of efficiently retaining an airbag cushion in stowed form.
RESOLUTION MEANS
An airbag device 100 is provided with a bag-shaped airbag cushion 112 in a prescribed rolled or folded stowed form, and a cover member 114 for covering an outer periphery of the airbag cushion 112 in stowed form formed of a ductile fabric material containing a plurality of polymer fibers. The cover member 114 has a hard portion 124 in a state in which at least a portion of the plurality of polymer fibers are melted together, and a soft portion 126 that bends more readily than the hard portion 124 in which the percentage of the plurality of polymer fibers that are melted is at least lower than that of the hard portion 124. The airbag device 100 is characterized by a state in which the cover member 114 is bent along the soft portion 126, covering at least a portion of the outer periphery of the airbag cushion 112 in stowed form.

Abstract: An improved modularization of an airbag cushion covered with a cover member and a method for manufacturing the same are disclosed. A first press is performed on the first portion of the cover member in a state where the folded airbag cushion is not covered with the cover member. The first portion has at least a portion that includes a position corresponding to an inflator within the folded airbag cushion. Next, the folded airbag cushion is covered with the cover member, and in the covered state, a second press is applied to at least a part of the second portion of the cover member excluding the first portion.

Abstract: An airbag which is a constituent of a side airbag device installed in the vehicle seat according to the present invention is provided with a main chamber which deploys toward the front of a side support portion of the seat, and a sub-chamber which accommodates an inflator and which deploys at a position inward of the main chamber in the width direction of the vehicle. The main chamber is divided, by means of a baffle panel, into a main front chamber at the front, and a main rear chamber at the rear. The sub-chamber is linked to the main rear chamber at a side in the width direction of the vehicle. When the airbag is deployed, the baffle panel extends along a front edge of the sub-chamber, as viewed from the width direction of the vehicle.
