FIG. 3 is a front view showing a second embodiment of the airbag cover 1 according to the present invention.
The difference from the first embodiment shown in FIG. 1 is that the large diameter portion 4, the intermediate diameter portion 6, and the small diameter portion 5 are formed in a step shape, and extend from the large diameter portion 4 to the small diameter portion 5. A piece of base fabric is cut so that the diameter is continuously reduced, and sewing is performed so that the diameter is continuously reduced linearly from the large diameter portion 4 to the small diameter portion 5, 3 is formed.
Further, when the impact of the collision is received, a gas is introduced into the airbag 9, and the slit 2 is formed so that the airbag cover 1 is broken when the airbag 9 is inflated and deployed.
Although the boundary between the large-diameter portion 4 and the intermediate-diameter portion 6 of the airbag cover 1 is unclear, if the airbag insertion side is the large-diameter portion 4, the workability of attaching the airbag cover 1 and the airbag 9 is improved. . Moreover, at the position where the sealing material of the airbag is located, it is possible to prevent overtightening by the airbag cover 1 (the volume in the airbag cover 1 is gradually changing, so that even if local tightening occurs, Can be shifted to the left and right to release the force).

図4は、本発明のエアバッグカバー1の第三実施例を示す正面図である。
前記図1に示した第一実施例との違いは、大径部4、中間径部6、小径部5を段状に形成したものに替えて、この第三実施例のものは、両端部を大径部4とし、中間部は中間径部6から構成され、略逆凹字状の段状に形成されるように一枚の基布を裁断し、大径部4、大径部4より小径である中間径部6、大径部4の順に形成し、略逆凹字状になるように縫製し、縫製部3を形成する。
さらに、衝突の衝撃を受けた際に、内部にガスが導入され、エアバッグが膨張展開する時に、エアバッグカバー1が破断するようにスリット2を形成したものである。
FIG. 4 is a front view showing a third embodiment of the airbag cover 1 of the present invention.
The difference from the first embodiment shown in FIG. 1 is that the large-diameter portion 4, the intermediate-diameter portion 6 and the small-diameter portion 5 are formed in a step shape, and the third embodiment has both end portions. Is formed of an intermediate diameter portion 6, and a single base fabric is cut so as to be formed in a substantially inverted concave stepped shape, whereby the large diameter portion 4 and the large diameter portion 4 are formed. The intermediate diameter portion 6 having a smaller diameter and the large diameter portion 4 are formed in this order, and are sewn so as to have a substantially inverted concave shape, thereby forming the sewing portion 3.
Further, the slit 2 is formed so that the airbag cover 1 is broken when the gas is introduced into the interior and the airbag is inflated and deployed upon receiving the impact of the collision.

図5は、本発明のエアバッグカバー1の第四実施例を示す正面図である。
前記図4に示した第三実施例との違いは、大径部4が両端部に形成したものに替えて、中間部だけ大径部4にして、その両側は中間径部6から構成され、略逆凸字状の段状に形成されるように、一枚の基布を裁断し、大径部4より小径である中間径部6を両側に中間部を大径部4に形成し、略逆凸部状になるように縫製し、縫製部3を形成する。
さらに、衝突の衝撃を受けた際に、内部にガスが導入され、エアバッグ9が膨張展開する時に、エアバッグカバー1が破断するようにスリット2を形成したものである。
筒状のエアバッグカバー1の大径部4に周長の小さな部分を、中間径部6に周長の大きな部分を収納すると、エアバッグカバー1の大径部4に収納した周長の小さな部分のエアバッグ9との関係は比較的ルーズな拘束となるので、インフレータから供給されるガスの流れがスムーズになり、予めエアバッグカバー1の大径部4に、ある程度のガスが充填されるまでエアバッグ9の膨張を継続させ、エアバッグカバー1の破断を遅らせることができる。
逆に、エアバッグカバー1の中間径部6に収納した周長の大きな部分のエアバッグ9との関係はタイトな拘束となるので、インフレータから供給されるガスが僅かに流入するだけでエアバッグカバー1が破断するように調整することができる。これにより、Bピラーに対応する位置等のように比較的速くにエアバッグ展開を行いたい箇所を選択的に設定することができる。
FIG. 5 is a front view showing a fourth embodiment of the airbag cover 1 of the present invention.
The difference from the third embodiment shown in FIG. 4 is that instead of the large diameter portion 4 formed at both ends, only the intermediate portion is made the large diameter portion 4, and both sides thereof are constituted by the intermediate diameter portion 6. Then, a single base fabric is cut so that it is formed in a substantially reverse convex stepped shape, and an intermediate diameter portion 6 having a smaller diameter than the large diameter portion 4 is formed on both sides, and an intermediate portion is formed on the large diameter portion 4. Then, sewing is performed to form a substantially reverse convex shape, and the sewing portion 3 is formed.
Furthermore, when the impact of the collision is received, the slit 2 is formed so that the airbag cover 1 is broken when the gas is introduced into the interior and the airbag 9 is inflated and deployed.
When a portion with a small circumference is stored in the large diameter portion 4 of the cylindrical airbag cover 1 and a portion with a large circumference is stored in the intermediate diameter portion 6, the small circumference stored in the large diameter portion 4 of the airbag cover 1 is used. Since the relationship with the airbag 9 is relatively loose, the flow of gas supplied from the inflator is smooth, and the large-diameter portion 4 of the airbag cover 1 is filled with a certain amount of gas in advance. The airbag 9 can be continuously expanded until the airbag cover 1 is broken.
On the contrary, the relationship between the airbag 9 and the airbag 9 having a large circumference stored in the intermediate diameter portion 6 of the airbag cover 1 is tightly constrained, so that the airbag is supplied only by a slight flow of gas supplied from the inflator. The cover 1 can be adjusted to break. As a result, it is possible to selectively set a location where the airbag is to be deployed relatively quickly, such as a position corresponding to the B pillar.

図6は、本発明のエアバッグカバー1の第五実施例を示す正面図である。
前記図5に示した第四実施例との違いは、大径部4を左、右どちらかの一端部に設け、残部は中間径部6から構成され、段状に形成されるように、一枚の基布を裁断し、大径部4を左右どちらか一方に、その残りは大径部4の径より小径な中間径部6を形成するように縫製し、縫製部3を形成する。
さらに、衝突の衝撃を受けた際に、内部にガスが導入され、エアバッグ9が膨張展開する時に、エアバッグカバー1が破断するようにスリット2を形成したものである。
エアバッグ9の非膨張部やガスの下流側に位置する膨張部を収納する部分を中間径部6とし、ガスの上流側に位置する膨張部を収納する部分を大径部4とすることで、エアバッグ9のガス上流部から下流側までにガスが所定量入った後に、エアバッグカバー1を破断することで、エアバッグ全体を同時に展開することができる。
エアバッグカバー1の大径部4と中間径部6との境界付近で、エアバッグカバー1内の容積を大きく変化させることができるので、エアバッグ9とエアバッグカバー1との寸法を適宜に設定することで、種々の展開特性を容易に調整することができる。
FIG. 6 is a front view showing a fifth embodiment of the airbag cover 1 of the present invention.
The difference from the fourth embodiment shown in FIG. 5 is that the large-diameter portion 4 is provided at one end on either the left or right side, and the remaining portion is constituted by the intermediate-diameter portion 6 so as to be formed in a step shape. A piece of base fabric is cut, and the large-diameter portion 4 is sewn so as to form either one of the left and right sides, and the rest is formed with an intermediate diameter portion 6 smaller than the diameter of the large-diameter portion 4 to form the sewn portion 3. .
Furthermore, when the impact of the collision is received, the slit 2 is formed so that the airbag cover 1 is broken when the gas is introduced into the interior and the airbag 9 is inflated and deployed.
A portion that accommodates the non-inflatable portion of the airbag 9 and the inflatable portion located on the downstream side of the gas is the intermediate diameter portion 6, and a portion that accommodates the inflatable portion located on the upstream side of the gas is the large diameter portion 4 After the predetermined amount of gas has entered from the gas upstream portion to the downstream side of the airbag 9, the airbag cover 1 can be broken to deploy the entire airbag at the same time.
Since the volume in the airbag cover 1 can be greatly changed in the vicinity of the boundary between the large diameter portion 4 and the intermediate diameter portion 6 of the airbag cover 1, the dimensions of the airbag 9 and the airbag cover 1 are appropriately set. By setting, various development characteristics can be easily adjusted.

上記いずれの実施の形態においても、大径部4および大径部より小径の中間径部6として説明したが、これに限定されるものではなく、例えば、エアバッグカバー1の大部分が大径部4であり、テザーベルトなど、嵩高くならない部分を収納する小径部5の長さがわずかな場合には、大径を中間径部6とし、小径を小径部としてもよいものである。   In any of the above-described embodiments, the large-diameter portion 4 and the intermediate-diameter portion 6 having a smaller diameter than the large-diameter portion have been described. However, the present invention is not limited to this. When the length of the small diameter portion 5 that accommodates the portion 4 that is not bulky, such as a tether belt, is small, the large diameter may be the intermediate diameter portion 6 and the small diameter may be the small diameter portion.

自動車内の前後の座席に着座している乗員を保護するカーテンエアバッグ、その他各種エアバッグを収納するエアバッグカバーとして全ての車種に利用することができる。   It can be used for all vehicle types as a curtain airbag for protecting passengers seated in front and rear seats in an automobile, and an airbag cover for storing various other airbags.
