PROBLEM TO BE SOLVED: To enhance the reliability of a sewing section at which panels of an airbag are sewed together.SOLUTION: A first panel 12 includes: a fold-back part 12c folded along an edge part 12a of the first panel; and a seam allowance part 12d laid on top of the fold-back part 12c, the second panel 13 being sewed in a first chain stitch 17 while being laid on top of the fold-back part 12c. Since a chain part 17a of the first chain stitch 17 is located between the fold-back part 12c and the seam allowance part 12d, the chain part 17a of the first chain stitch 17 is covered by the seam allowance part 12d of the first panel 12. Therefore, the chain part 17a of the first chain stitch 17 is prevented from rubbing against other members during deployment of the airbag 11. Consequently, the reliability of a sewing section 14 can be enhanced.SELECTED DRAWING: Figure 4
【課題】 エアバッグのパネルどうしを縫製する縫製部の信頼性を高める。【解決手段】 第1パネル12は、その端部12aに沿って折り返された折り返し部12cと、折り返し部12cに重なり合う縫い代部12dとを備え、第2パネル13は折り返し部12cに重なり合った状態で第1チェーンステッチ17により縫製され、第1チェーンステッチ17の鎖部17aは折り返し部12cおよび縫い代部12d間に有するので、第1チェーンステッチ17の鎖部17aを第1パネル12の縫い代部12dで覆うことで、エアバッグ11の展開時に第1チェーンステッチ17の鎖部17aが他部材に擦れるのを防止して縫製部14の信頼性を高めることができる。【選択図】 図4
