  • Airbag and airbag device
    Patent number: 8408597
    Abstract: A sewing thread of a sewn portion provided in an air chamber of an airbag is prevented from being cut during manufacturing, and damage to the airbag starting from an end of the sewn portion is suppressed. An inner connecting portion (30) provided in an air chamber of an airbag, at which opposing base fabrics are connected to each other, is formed of a first sewn portion (31) formed by sewing the base fabrics together so as to divide the air chamber, a second sewn portion (32) that surrounds an end (31T) of the first sewn portion (31) to protect it, and an adhesive layer (35) formed around the sewn portions (31) and (32). Ends (32T) of the second sewn portion (32) disposed on both sides of the first sewn portion (31) are formed such that they are continuously sewn toward an inner region (R) of the second sewn portion (32) along the end (31T) at a predetermined distance therefrom, such that they project further than the end (31T) of the first sewn portion (31), without intersecting the first sewn portion (31).
