Abstract

Abstract A seat structure having a side impact air bag apparatus which can reduce costs, and can be assembled with improved workability. The air bag apparatus (14), which extends in the longitudinal direction of a seat back, is disposed in a side portion (12A) provided on the outer side of the seat back (12) in the widthwise direction of the vehicle. An air bag (32) of the air bag apparatus is folded and the folded air bag is integrated with a seat back pad (48) during a foaming process, and is fixed to a seat back frame (18) together with other structural components of the air bag apparatus. When the seat back pad is made by foaming, the air bag in the folded state is placed within a molding die, and a foaming material is foamed to obtain the seat back pad integrated with the air bag.
