The airbag device is generally a gas generator, an airbag which is inflated by gas from the inflator, and these airbags. And an airbag case for storing the inflator.
The airbag device is not limited to the one that restrains the occupant from the front, and in recent years, a device that restrains the occupant from the side has been developed as disclosed in Japanese Patent Laid-Open No. 6-64491. In such a side airbag device, an airbag module is embedded, for example, on the door side of a seat back, and in the vicinity of the airbag case opening, a cover material covering the airbag case opening and a seat surface are covered. The outer cover material is sewn, and the sewn portion is ruptured by breaking the airbag at a predetermined deployment pressure, and the airbag is deployed from the ruptured gap.

問題点もあった。However, since the sewn portion is ruptured mainly due to the difference in the elongation of the covering material and the elongation of the sewing thread, the perforation of the covering material, that is, the covering material itself is broken, so that the covering material has a low strength. However, it is not possible to guarantee sufficient entry and exit durability, and the airbag does not rupture from a certain location and the deployment trajectory of the airbag is not stable.The strength of the sewing thread is the strength between the perforations of the cover material. There is a restriction that it has to be stronger, and there is a problem that productivity is inferior because a high degree of balance between quality and technology is required for the covering material and sewing. Further, the opening of the airbag case is covered by a case lid that can be opened and closed, which causes a problem that complicated work such as assembling of the case lid is forced, and the case cover damages the skin material. Therefore, there is also a problem that the type of skin material used is limited, which is limited in terms of cost and design.

来通り縫合部7cで縫合してある。The seat cover 6 comprises a seat surface covering portion 6a, a gusset covering portion 6b and a seat back covering portion 6c. In the present invention, the seat surface covering portion 6a and the gusset covering portion 6b are provided. Is not what was sewn directly as in the prior art, but as shown in FIG. 3, the front end is sewn to the seat surface covering portion 6a as a sewn portion 7a to cover the opening 4 of the airbag case 3 and The cover material 10 such as a belt-shaped leather material whose ends are fixed to the airbag case 3 is sewn at a position slightly rearward from the sewn portion 7a which is not far from the opening 4 as a sewn portion 7b, and the front position of the gusseted cover portion 6b is sewn. The front portion of the stitched portion 7b is inserted into the gap between the edge of the sheet surface covering portion 6a and the cover material 10. An airbag guide portion 11 that restricts the bulging direction of the airbag 2 that bulges from the opening 4 is provided at a position of the cover material 10 facing the opening 4 of the airbag case 3. Incidentally, as shown in the drawing, the gusseted covering portion 6b and the seat back surface covering portion 6c are sewn together by the sewn portion 7c as usual.

糸自身の破断により行なわれることとなる。The cover material 10 is made of, for example, a synthetic resin leather cloth or a synthetic fiber cloth which does not affect the feel of a sheet such as nylon or polyester and has a small elongation, and the deployment pressure of the airbag 2 is increased. It is preferable to make it easy to concentrate on the sewn portion 7b with the gusseted covering portion 6b, but synthetic resin plate or synthetic fiber cloth may be used if the touch feeling of the sheet is disregarded, and a high-class design effect is excellent. When it is desired to obtain a sheet, as shown in FIG. 6, the sewn portion 6b is sewn together so that the bead 12 is arranged in the gap between the cover material 10 and the gusset covering portion 6b. When the cover material 10 is made of vinyl resin, leather, or the like and has a tensile strength smaller than that of the thread of the stitched portion 7b, tearing when the airbag is actuated does not occur.
This is done by breaking the cover material itself in part b,
On the other hand, when the cover material 10 is made of a synthetic resin plate, synthetic fiber cloth, or the like and has a higher tensile strength than the thread of the stitched portion 7b, the tearing during the airbag operation is caused by the breakage of the thread itself of the stitched portion 7b. Will be done.

前述のとおりである。With such a structure, when the airbag 2 is inflated slightly at the initial stage when the inflator of the airbag apparatus 1 is activated, the airbag case 3 is expanded by the deployment pressure as shown in FIG. In the cover material 10 that closes the opening 4 of the above, the fin-shaped member 10a surrounded by the U-shaped slits or perforations formed at the position corresponding to the opening 4 is pushed up and swelled in the initial stage of swelling. The airbag 2 begins to bulge outward while being regulated in direction from the airbag guide portion 11 that regulates the bulging direction of the airbag 2 that bulges from the opening 4 of the airbag case 3. As shown in FIG. The inflation pressure of the airbag 2 is concentrated on the sewn portion 7b between the cover material 10 and the gusseted covering portion 6b while the bag 2 is inflated and regulated in direction by the airbag guide portion 11. Then, due to this stress concentration, the cover material 10 is easily broken from the stitched portion 7b with the gusseted covering portion 6b, so that the gusseted covering portion 6b that is not directly sewn with the sheet surface covering portion 6a is entirely extruded. Immediately, the airbag 2 will inflate toward the side surface of the occupant. In addition,
When vinyl resin, leather, or the like is used as the cover material 10, the tearing at the time of operating the airbag is performed by breaking the cover material itself at the stitched portion 7b.
As described above.

In addition, since the airbag 2 is controlled so as not to inflate too much inside the gusseted covering portion 6b, a stable deployment trajectory of the airbag 2 can be guaranteed. Further, unlike the conventional case, since the opening of the airbag case 3 is not covered with the case lid, the case lid does not damage the skin material. Therefore, the type of the skin material to be used is not limited. This is advantageous in terms of cost and design, and even in normal use, the gusseted covering portion 6b is free from the feeling of foreign matter and provides a comfortable seat feeling.

いものである。As is apparent from the above description, the present invention does not rupture the conventional skin material itself, but uses the skin material covering the opening of the airbag case and the skin material covering the seat surface. With a novel structure that creates a trigger for the breaking of the sewing thread to be sewn, the sewing thread can be reliably and quickly ruptured by a slight deployment pressure of the airbag at the initial stage of airbag operation to easily tear the sewn portion. In addition, it is possible to stabilize the airbag's deployment trajectory by keeping the breakage points constant, and the strength of the covering material and the sewing thread can be easily balanced, and the workability of assembly is also excellent. It also has the advantage that productivity can be greatly improved, and that there is no limitation on the type of skin material used, which is advantageous in terms of cost and design. Therefore, the present invention greatly contributes to the industrial development as a vehicle seat equipped with an airbag device that protects an occupant from a side collision that eliminates the conventional problems.
