DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat incorporating an airbag for a side collision of a vehicle, and more particularly to a seat frame, a pad material attached to the seat frame, and a skin material covering the pad material. An airbag module attached to the side of the vehicle seat and attached to the seat frame; a gas generator housed and fixed in the airbag module; and a gas generator when the gas generator is activated. The present invention relates to a side-impact airbag-incorporated seat including an airbag body fixed to the airbag module so that gas to be ejected flows into the airbag module.

[0002]

2. Description of the Related Art Conventionally, in order to avoid a direct impact between a side wall of a vehicle body such as a door deformed by an impact load and a seated occupant in a side collision of a vehicle, various airbag devices have been used. There have been proposed, for example, vehicle seat structures as disclosed in JP-A-4-50052 and JP-A-7-215159.

[0005] As shown in FIG. 5, the seat structure of this vehicle includes a seat back 1 on the outside of the side of the seat back 1 facing the side wall of the vehicle body.
An airbag device 11 is provided which inflates in a space perpendicular to the vehicle body side wall or between the occupant and the vehicle body. The airbag device 11 is disposed behind the pad material 5 of the seat back 1 in consideration of the getting on / off and cushioning of the seat.

As shown in FIG. 5, an airbag module 13 of an airbag device 11 is provided on a side frame 3 of a seat back 1, and a gas generator 15 is fixed to the airbag module 13 or the side frame 3. An airbag main body 17 is fixed to the airbag module 13 so that gas ejected from the gas generator 15 flows in when the gas generator 15 is operated.

[0005] The skin material 7 of the seat back 1 includes a main cloth 7a, a main side cloth 7b and a horizontal gusset cloth 7c, and the airbag body 17 is provided with a sewing portion 8 of the main side cloth 7b and the horizontal gusset cloth 7c. It is made to break and bulge. Further, a J-shaped hook 9 is fixed to an end portion of the horizontal gusset cloth 7c of the skin material 7 by sewing or the like, and the J-shaped hook 9 is locked to the side frame 3.

[0006]

However, in such a conventional technique, when the airbag body 17 of the airbag device 11 bulges forward from the side portion of the seatback 1, it is difficult to prevent the airbag body 17 from swelling.
As shown in FIG. 6, an impact force is applied to the J-shaped hook 9 of the skin material 7, and the J-shaped hook 9 is deformed, or a force is applied in the opposite direction, so that the J-shaped hook 9 and the side are joined together. Frame 3
The J-shaped hook 9 comes off, and the main side cloth 7b and the horizontal gusset cloth 7c of the skin material 7 are not retained.
Therefore, sufficient tension cannot be applied to the scheduled break portion of the sewn portion 8, and the scheduled break portion of the sewn portion 8 may not be rapidly broken.
