4 are inserted into the notch 11 of the seat frame 2 over the upper and lower portions of the inflator 12 and are bent inward, so that the mounting holes 16 are inserted into the upper and lower bolts 13. Through each. Finally, a nut 18 is attached to the bolt 13, and both ends 14, 15 and the belt portion 17 are fixed in a state of being overlapped. Since the belt portion 17 is folded back from the notch 11 and overlapped on both ends 14 and 15 as described above, the airtightness of the mounting portion of the airbag 9 is high, and the mounting strength is high. Further, since the airbag 9 can be directly attached to the seat frame 2 and the inflator 12, the structure is simple and the assembly is easy. Further, the number of parts is small, and the cost can be reduced.

して、乗員を側面衝突から保護することができる。When the airbag 9 is inflated, tension is applied to the entire outer skin 4 so as to extend, and the first seam h1 located at the outermost surface of the extension 5 is broken by the tension (see FIG. 7). When the first suture portion h1 breaks, a part of the extension portion 5 is sent to the side of the epidermis 4 and the epidermis 4 is slackened (margin). Therefore, the portion of the skin 4 pressed by the airbag 9 inflates to the front side, that is, the front side along the inside of the vehicle compartment, together with the airbag 9.
Next, the second suture portion h2 is broken (see FIG. 8), and thereafter,
Since the third suture portion h3 is sequentially broken, loosening (margin) occurs one after another in the epidermis 4, and the portion of the epidermis 4 corresponding to the airbag 9 inflates forward with the airbag 9 in a non-cleaved state. , Can protect the occupants from side collisions.

The range A in FIG. 10 shows until the first suture portion h1 breaks, the range B shows after the first suture portion h1 breaks, the range C shows after the second suture portion h2 breaks, D is the third
This shows a state after the suturing portion h3 has been broken. When the airbag 9 is inflated by sequentially breaking the first to third suture portions h1, h2, and h3, the airbag 9 is ruptured at a stretch as in the conventional case, and the airbag 9 is inflated. Since the internal pressure of the airbag 9 decreases stepwise without abruptly decreasing, it is more preferable in protecting the occupant.
