Abstract: The present invention provides: an airbag cover which is formed by integrally joining a first base fabric and a second base fabric having mutually different characteristics, and has a joint portion that ensures high productivity in mass production; a method for manufacturing the airbag cover; and an airbag device. The present invention relates to an airbag cover for storing a bag-shaped cushion which is rolled up or folded before being inflated and deployed by a gas supplied from an inflater, and relates to a method for manufacturing the airbag cover. The airbag cover is characterized by comprising a first base fabric made of a plain-woven fabric or a non-woven fabric made from chemical fibers, and a second base fabric containing fibers different from the fibers constituting the first base fabric, and having an initial tensile resistance value higher than an initial tensile resistance value of the first base fabric.

Abstract: The present invention is a side airbag device housed in the side support part of a vehicle seat and includes an airbag for restraining an occupant and an inflator. The airbag includes a first bag housing the inflator which is capable of inflating and deploying, and a second bag capable of inflating and deploying on the side of the first bag. The second bag is configured to be deployed by inflation gas flowing in from the first bag. At the upper edge of the second bag, an inclined part is formed that is inclined to be lower at the front thereof than at the rear thereof when viewed from the vehicle width direction. The front portion of the inclined part is configured to be located lower than the center line extending in the longitudinal direction of the upper arm of the occupant seated in a vehicle seat.

Abstract: PROBLEM:
To provide a side airbag device that can be stored compactly.
RESOLUTION MEANS
The present invention is an airbag device to be stowed in a vehicle seat, comprising:
an airbag cushion that restrains an occupant by expanding and deploying;

an inflator arranged on the inner side of the seat frame which supplies expansion gas to the airbag cushion; and

a cover member made of a ductile material that melts and shrinks under heat and pressure to retain the airbag cushion. The airbag cushion includes a rear chamber section where the inflator is stowed, and a front chamber section that extends forward from the rear chamber section that is arranged outside of the seat frame when stowed. The cover member is then configured to heat and pressurize the region corresponding to the front chamber section of the airbag cushion, thereby pressurizing and retaining the relevant section of the airbag cushion.

Abstract: A far side side airbag device provided on the side part in the center in the width direction of a backrest portion of either of separated seats arranged in the width direction of a vehicle, which restrains the movement of an occupant. A cushion and an inflator expands and deploys the cushion. The cushion has a first portion and a second portion that expand and deploy onto the front surface of each of the adjacent separated seats when a signal is received to restrain the occupant and capture the side part of the occupant, and a center portion provided in between the first portion and the second portion. A protruding part is formed on the center portion in order to capture the head of the occupant.
