エアバッグ装置のエアバッグに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an airbag of an airbag device installed in a vehicle, and more specifically, the lower gas inlet periphery is connected to a mounting member, and the gas flow When gas flows in from the inlet, it is expanded from the folded state, and when the internal pressure rises after expansion, the conduction shield is ruptured and the auxiliary bag section provided in a part of the airbag is inflated, suppressing the increase in internal pressure. The present invention relates to an airbag of an airbag device that can be suppressed.

せてしまう虞れがあった。そのため、その後の内圧上昇
時には膨らませるべき補助袋部が無くなり、内圧上昇を
抑制できなくなる虞れがあった。However, in this airbag, the auxiliary bag section is simply disposed on a part of the peripheral wall through the conduction shielding section, and when the airbag attempts to expand due to gas flowing in from the gas inlet, There was a risk that a large bow tension would act on the peripheral wall, and the sewing thread of the conduction shielding part would break before the expansion was completed, causing the auxiliary bag part to inflate. Therefore, when the internal pressure increases thereafter, there is no longer any auxiliary bag portion to be inflated, and there is a possibility that the increase in internal pressure cannot be suppressed.

エアバッグを提供することを目的とする。This invention solves the above-mentioned problem, and when the airbag is expanded, the auxiliary bag portion does not inflate and the airbag expands into a predetermined shape, and when the internal pressure increases after the expansion is completed, the auxiliary bag portion expands and the expansion ends. It is an object of the present invention to provide an airbag of an airbag device that can reliably suppress a subsequent increase in internal pressure.

対向部位をガス流入口に接近させて上側・下側バッグ基
布の外周縁側を上方へ折り畳んだ状態としている。<Operations and Effects of the Invention> In the airbag of the airbag device according to the present invention, in the folded state, the portions of the upper bag base fabric C facing the gas inlet are brought closer to the gas inlet, and the upper and lower bag base fabrics are folded. The outer periphery side is folded upward.

で下側バッグ基布が次第に伸張され、拡開終了時では、
取付部材じ連結されたガス流入口周縁が最も引張力を受
けることとなる。When a predetermined gas flows in from the gas inlet and expands, at the beginning of the expansion, the portion of the upper bag base fabric facing the gas inlet is pushed upward and begins to expand.
Before the expansion is completed, the upper bag base fabric is already stretched, and the lower bag base fabric is gradually stretched, and when the expansion is completed,
The periphery of the gas inlet, which is connected to the mounting member, receives the most tensile force.

く、導通遮蔽部が破断する虞れが生じない。Therefore, in the airbag according to the present invention, even if the maximum tensile force is applied to the periphery of the gas inlet at the end of expansion, the conduction shielding part connected to the auxiliary bag part is separated from the periphery of the gas inlet, Furthermore, since it is disposed on the upper bag base fabric which is separate from the lower bag base fabric, the tensile force acting on the periphery of the gas inlet is difficult to be transmitted to the conduction shielding part. There is no risk of breakage.
