BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat structure in which an airbag for protecting an occupant by breaking and inflating a seat at the time of collision of a vehicle is embedded under the fabric of the seat. More specifically, the present invention relates to an improvement for surely and swiftly deploying the airbag in the expected position and direction.

2. Description of the Related Art Conventionally, in the event of a side collision of a vehicle, an actual flat opening 1 is provided to prevent direct contact between an occupant and a member forming a vehicle body side wall such as a door which is deformed by a side impact load.
It has been proposed to use an airbag device, as disclosed in Japanese Patent Publication No. 117957. In the one disclosed in this publication, an airbag is stored in a folded state inside an armrest arranged on the inner wall surface of a door, and at the time of a vehicle side collision, the airbag is instantly inflated to the inside of the passenger compartment to occupant. By intervening between the door and the door, direct contact between the deforming door and the occupant is prevented, and the occupant is protected.

However, in such a structure equipped on the armrest of the door or the like, the cushioning effect of the airbag may be significantly reduced. This is because the seat of the vehicle is slidably adjustable in the height direction and the front-rear direction of the seat portion (hereinafter referred to as a seat cushion) of the seat with respect to the vehicle body, and further, the backrest portion (hereinafter referred to as seat back). ) Is also adjustable, and when the position of the seat or backrest of the seat is adjusted, the relative positional relationship between the occupant and the storage position of the airbag changes accordingly. There is a risk that the air bag may be displaced from the occupant position where the maximum protection effect can be imparted.

Therefore, in order to solve such a problem,
It is possible to embed an airbag in the seat itself.
It is proposed in Japanese Patent Laid-Open No. 50052, Japanese Patent Laid-Open No. 6-64491, and the like. In the technologies disclosed in these publications, an airbag that bulges between a side wall portion of a vehicle body and an occupant during a side collision of a vehicle is embedded in a position near a side end of a seat back. As described above, when the seat itself is equipped, the relative positional relationship between the airbag and the occupant does not change due to the position adjustment of the seat, and the inflation position of the airbag with respect to the occupant can be stabilized. .

However, since the airbag is inflated and deployed rapidly in a very short time,
Actually, the position where the seat ruptures due to the inflation of the airbag is strictly regulated, and further, the deployment position of the inflated airbag varies if the timing at which the seat tears is not strictly regulated. Or, the time required to complete the expansion due to swelling may become longer, and the expected sufficient protection effect may not be obtained. That is, it is not enough to simply equip the airbag, and the deployment position and the deployment direction of the airbag are surely determined at the initial stage of the inflation of the airbag, and the airbag can be ruptured and swollen quickly. It is necessary to give sufficient consideration to the characteristics of the sheet material. However, in the vehicle seat structure in which the conventional airbag is embedded, including the technology disclosed in the above-mentioned publication, the deployment position and the deployment direction of the airbag at the initial stage of the inflation of the airbag are restricted, or the airbag does not cover the seat. There was insufficient consideration for quickly breaking and swelling, and it was a future task to solve these problems.

SUMMARY OF THE INVENTION The above object of the present invention is to provide a vehicle seat in which an airbag for protecting an occupant by rupturing and inflating the seat at the time of collision of the vehicle is embedded under the fabric of the seat. In the structure, the sheet material covering the airbag is a woven fabric in which a first woven thread and a second woven thread are woven together, and the first woven thread is woven when the airbag swells. Woven along the direction in which the dough should be cleaved, and
This is achieved by a vehicle seat structure characterized in that a second woven yarn is woven in a direction substantially orthogonal to the first woven yarn.

And a second woven yarn are woven together, the first woven yarn is woven along the direction in which the fabric is to be cleaved when the airbag is inflated, and The second weaving yarn is woven in a direction substantially orthogonal to the first weaving yarn, because the shearing force acting on the fabric due to the bulging of the airbag concentrates on the second weaving yarn. , The second weaving yarn is easily cut along the assumed tearing direction, stabilizing the timing of the tearing of the sheet material at the initial stage of the inflation of the airbag, and at the same time developing the sheet material at the tearing position. It can be regulated within a certain range of directions. Therefore, at the time of operating the airbag, the seat material is quickly broken in the assumed airbag deployment direction, and the airbag can be surely inflated and deployed in the intended direction.
It is possible to secure high reliability for protection of passengers.
