Airbag apparatus

摘要

An airbag apparatus (1) includes an airbag (5) that has a first portion and a second portion. The airbag (5) is folded such that the first portion approaches the second portion. The folded airbag (5) has an elongated shape extending along a first direction. An inlet (12a) is formed in the airbag (5). By receiving the supply of gas through the inlet (12a), the folded airbag (5) is inflated while being deployed in a second direction perpendicular to the first direction, such that the first portion moves away from the second portion. The inlet (12a) is arranged in a part of the folded airbag (5) that is located in a trailing side in the second direction. A first attachment portion (16) is provided in the same part of the folded airbag (5). A second attachment portion (27) is provided in each of the ends of the folded airbag(5). The folded airbag (5) is installed in a ceiling of a vehicle (2) by means of the first attachment portion (16) and the second attachment portions (27). When the airbag (5) is being deployed and inflated, the second attachment portions (27) function to apply an outward tension along the first direction to the airbag (5).
