造作業が面倒になる。However, in such a conventional technique, the air bag, the gas generator, etc. are attached, and finally the entire seat back is covered with the skin cover. Wrinkles may occur on the epidermis cover depending on how the bag or the like is attached. Therefore, as a measure for eliminating the wrinkles, it is necessary to apply steam to the wrinkles, which makes the manufacturing work of the seat back troublesome.

端末同士が縫製部３４において結合されている。This embodiment is different from the unitized structures of the previous embodiments and shows an improved structure in which the guide function of the lid in the conventional non-unitized structure is strengthened. That is, the airbag 18, the gas generator 19, and the lid 32 are sequentially attached to the side panel 33 without being unitized, and the pad 10 and the skin cover 11a are also provided outside the lid 32. The outer cover 11a on the side and the outer cover 11b on the center are joined at their ends at a sewing portion 34.

部３４付近に位置させていた。On the other hand, the rear end 35 of the lid 32 is fixed to the side panel 33 with a screw 37, and the front end 36 is folded back toward the rear by a predetermined length D. The structure in which the front end 36 is folded back is different from the conventional structure. Conventionally, the front end was simply positioned near the sewn portion 34 as a free end without being folded back.

ガイド機能が向上する。According to this embodiment, since the front end 36 of the lid 32 is folded back, the airbag 18 is deployed forward at the time of a side collision of the vehicle, and the sewing portions of the skin covers 11a and 11b are sewn. When 34 is broken and the lid 32 is opened, the length of the lid 32 is increased by the amount of the front end 36. Therefore, as the length of the lid 32 at the time of opening is increased, the guide function of the airbag 18 by the lid 32 is improved.

になる。According to the invention as set forth in claim 1, the airbag and the gas generator are integrated into one independent airbag unit, and the side panel in the region where the pad on the side of the seat back and the skin cover are not present. Since the mounting condition of the airbag unit does not affect the skin cover or the pad, the seat sewing workability is good. Further, since the airbag unit is not related to the skin cover or the pad, it is possible to attach the airbag unit, which requires careful handling, at the end of the seat manufacturing process, which also improves the workability of manufacturing the seat. .
It should be noted that the removal and replacement of the airbag unit will be easier than before.

が行い易い。According to the fifth aspect of the present invention, a bolt is formed which extends obliquely inward and rearward from the gas generator through the storage container and is inserted into the bolt hole formed in the corresponding portion of the side panel. Since the structure is such that the bolts are fixed by the nuts, the bolts are located on the opposite side of the airbag deployment direction (obliquely outside front), so that the airbag deployment reaction force can be reliably received. Moreover, since the bolts are directed diagonally inward and rearward, it is easy to perform the nut fastening work from the back of the seat back.
