８が挿通される貫通孔９が形成されている。In the figure, the airbag 2 consists of an airbag body 3 and several laminated reinforcing sheets 4.4. The reinforcing sheet 4.4 is laminated and sewn to the peripheral edge of the inner circumferential surface 5 of the airbag body 3 to which the inflator is attached. A through hole 9 is formed in the peripheral edge of the inflator mounting hole 6 of the airbag 2, into which a mounting bolt 8 is inserted when the airbag 2 is assembled to the bag holder 7.

らなる。The airbag protection laminate 10 is disposed on the inner circumferential surface 11 of the near bag 2. This airbag protection laminate 10 is made by coating a cloth 12 with a coating layer 13 made of flame-retardant rubber, synthetic resin, or metal. The coating 1113 is made of, for example, chloroprene rubber, silicone rubber, epichlorohydrin rubber, , made of aromatic polyamide resin or aluminum foil.

熱風じ曝されるのを防止する。The covering layer 13 covers at least the surface of the cloth 12, that is, the surface that does not come into contact with the inner circumferential surface II of the airbag. The airbag protection laminate 10 is a flat annular body, and the inner peripheral portion 14 has a through hole 15 through which a bolt 8 is inserted when the airbag protection laminate 10 is assembled to the bag holder 7. It is formed at a predetermined location. The width of the airbag protection laminate 10 is larger than the width of the annular retainer 16, so that the outer peripheral portion 17 of the airbag protection laminate 10 can cover the seam 18 formed by sewing. Therefore, the airbag protection laminate 10 blocks the hot air from the inflator 1 and prevents the seam 18 from being directly exposed to the hot air.
