Abstract

In a seat with a side air bag system, of two stay clothes (9, 10) continuously extending from a sewing portion corresponding to a breaking portion (8, 80) of a trim cover (7), one stay cloth (9) is taken into a cavity (3) from an opening edge of a back pad (2), the other stay cloth (10) is taken into the cavity (3) of the back pad (2) from a front side of an air bag system (1) so as to wrap the air bag system (1) with two stay clothes (9, 10), the stay clothes (9, 10) are connected and supported by wear plates (11, 12, 110) gripping and fixing a take-in end of each of the stay clothes (9, 10) between the air bag system (1) and the side plate (6). Accordingly, each of the stay clothes (9, 10) can be easily assembled and the air bag system (1) can be directly wrapped with two stay clothes so as to efficiently concentrate an inflating pressure of the air bag on the sewing portion corresponding to the breaking portion (8, 80) of the trim cover (7), thereby quickly inflating and developing the air bag.
