1. An airbag comprising:
- a first panel and a second panel, which have peripheral portions having inner surfaces facing and connected to each other, elastic adhesive disposed between the inner surfaces of the first and second panels at the peripheral portions to connect the first and second panels, and a yarn sewed along the peripheral portions within a range of the width of the elastic adhesive to connect the first and second panels together with the elastic adhesive so that when the first and second panels are pulled in inflating the airbag, the adhesive is pulled outwardly to absorb an expansion force, said yarn comprising a first seam positioned outside and a second seam positioned inside relative to a center of the first and second panels, a sewing yarn for the second seam being thinner than a sewing yarn for the first seam.

Abstract
An airbag is provided which securely prevents gas leakage through seams between panels and has excellent productivity. The airbag 10 has panels 1, 2. Peripheral portions of the panels 1, 2 are bonded with silicone adhesive 5 and also sewn together by sewing yarns 6A, 6B. Seams of the sewing yarns 6A, 6B may be coated by silicone sealant. The sewing yarn 6A composing an inner seam is thinner than the sewing yarn 6B composing an outer seam so that the sewing yarn 6A is broken during the inflation of the airbag 10, thereby absorbing energy.
