This was achieved by placing a reinforcing cloth in the position where it was included.

以下、本発明を実施するための形態例を、図１及び図２を用いて説明する。
図１は本発明のサイドエアバッグ装置を構成するエアバッグの説明図、図２は図１の要部拡大図である。 Hereinafter, exemplary embodiments for carrying out the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is an explanatory view of an airbag constituting the side airbag device of the present invention, and FIG. 2 is an enlarged view of a main part of FIG.

本発明のサイドエアバッグ装置は、車両側面からの衝突時に、例えば運転席に着座し、シートバックに体を預けた運転者とドアの間に、シートバックのドア側の側部から前方に向けてエアバッグを展開させ、乗員を保護するものである。   The side airbag device of the present invention is directed forward from the side of the seat back on the door side between the door and the driver who sits on the driver's seat and leaves the body in the seat back, for example, in the event of a collision from the side of the vehicle. The airbag is deployed to protect the passengers.

サイドエアバッグ装置のエアバッグ１１は、例えば１枚の基布１２を中央部分で二つ折りにして重ね合わせることで車内側と車外側の布パネル１２ａ，１２ｂとし、前記折り曲げ部１２ｃを除く全外周を縫製して袋状に形成している。   The airbag 11 of the side airbag device has, for example, a fabric panel 12a, 12b on the vehicle inner side and the vehicle outer side by folding a single base fabric 12 into two at the center and overlapping the outer periphery except for the bent portion 12c. Are formed into a bag shape.

その際、この外周縫製１３の終端部１３ａ同士を離間させて、エアバッグ１１が展開した後或いは乗員がエアバッグ部に当接した後にガスを排気することで、乗員への衝撃を緩和するベントホール１４を形成している。   At that time, vents that reduce the impact on the occupant by separating the end portions 13a of the outer periphery sewing 13 and exhausting the gas after the airbag 11 is deployed or after the occupant comes into contact with the airbag portion. A hole 14 is formed.

また、基布１２を重ね合わせた車内側と車外側の布パネル１２ａ，１２ｂの相対する内側に、補強布１５ａ〜１５ｄを配置して基布１２と一緒に縫製することで、インフレータから送られてくるガスの熱および圧力による外周縫製１３への影響を小さくしている。   Further, the reinforcing cloths 15a to 15d are arranged on the inner side and the inner side of the cloth panels 12a and 12b opposite to each other where the base cloth 12 is overlapped, and are sewn together with the base cloth 12 to be sent from the inflator. The influence on the outer periphery sewing 13 by the heat and pressure of the coming gas is reduced.

なお、図示省略したインフレータは、前記エアバッグ１１を上下方向に立てた状態で、エアバッグ１１の後端部１１ａにて包み込まれるようにして内蔵されている。   The inflator (not shown) is built in such a manner that the airbag 11 is wrapped in the rear end portion 11a of the airbag 11 in a state where the airbag 11 is erected in the vertical direction.

本発明は、基布１２の外周を縫製して袋状に形成する際、外周縫製１３の終端部１３ａ同士を離間させてベントホール１４を形成しているエアバッグ１１の、前記外周縫製１３の終端部１３ａを、図２に示すように折り返すことを特徴としている。なお、図２中の１３ｂは前記終端部１３ａを折り返した折り返し部を示す。   In the present invention, when the outer periphery of the base fabric 12 is sewn and formed into a bag shape, the outer peripheral sewing 13 of the airbag 11 that forms the vent hole 14 by separating the end portions 13a of the outer peripheral sewing 13 from each other is formed. The terminal portion 13a is folded back as shown in FIG. Note that reference numeral 13b in FIG. 2 denotes a folded portion obtained by folding the end portion 13a.

その際、ベントホール１４が布パネル１２ａ，１２ｂの外周よりエアバッグ１１の内側に引き下がって構成されるように、布パネル１２ａ，１２ｂの前記ベントホール１４を形成する部分の外周側の周辺に、布パネル延長部１２ａａ，１２ｂａを形成している。   At that time, around the outer peripheral side of the portion forming the vent hole 14 of the fabric panels 12a and 12b, the vent hole 14 is configured to be pulled down from the outer periphery of the fabric panels 12a and 12b to the inside of the airbag 11. Fabric panel extensions 12aa, 12ba are formed.

この布パネル延長部１２ａａ，１２ｂａは、図１では、ベントホール１４を形成する部分近傍の布パネル１２ａ，１２ｂの外周上の１点から、当該外周からはみ出すようにベントホール１４方向に伸ばした直線（接線）または曲線を、ベントホール１４直近から布パネル１２ａ，１２ｂの外周に戻した形状である。   In FIG. 1, the cloth panel extensions 12aa and 12ba are straight lines extending in the direction of the vent hole 14 so as to protrude from the outer periphery of the cloth panel 12a and 12b in the vicinity of the portion where the vent hole 14 is formed. (Tangent) or a curved line is returned to the outer periphery of the fabric panels 12a and 12b from the position closest to the vent hole 14.

そして、外周縫製１３の終端部１３ａを、前記布パネル延長部１２ａａ，１２ｂａとベントホール１４の境界付近の布パネルコーナ部１２ａｂ，１２ｂｂ近傍に位置させ、前記折り返し部１３ｂを布パネル延長部１２ａａ，１２ｂａに延伸させている。   Then, the end portion 13a of the outer periphery sewing 13 is positioned in the vicinity of the cloth panel corner portions 12ab and 12bb near the boundary between the cloth panel extension portions 12aa and 12ba and the vent hole 14, and the folded portion 13b is placed in the cloth panel extension portion 12aa and It is extended to 12ba.

加えて、本発明では、前記折り返し部１３ｂにも、補強布１５ａ〜１５ｄが位置するように、図１（ｂ）に示すように、補強布１５ａ〜１５ｄの外周形状を基布１２の外周形状と同じ形状にしている。なお、図１，２中の１５ａａ〜１５ｄａは補強布延長部、１５ａｂ〜１５ｄｂは補強布コーナ部を示す。   In addition, in the present invention, the outer peripheral shape of the reinforcing cloths 15a to 15d is changed to the outer peripheral shape of the base cloth 12 as shown in FIG. 1 (b) so that the reinforcing cloths 15a to 15d are also located in the folded portion 13b. It has the same shape as In FIGS. 1 and 2, 15aa to 15da denote reinforcing cloth extensions, and 15ab to 15db denote reinforcing cloth corners.

上記構成の本発明のエアバッグ１１を採用した場合は、エアバッグ１１の展開時にベントホール１４の近傍の縫い目に作用する応力を、外周縫製１３の終端部１３ａのみならず折り返し部１３ｂでも負担することになるので前記応力を分散することができる。   When the airbag 11 of the present invention having the above-described configuration is employed, the stress acting on the seam in the vicinity of the vent hole 14 when the airbag 11 is deployed is borne not only by the terminal end portion 13a of the outer peripheral sewing 13 but also the folded portion 13b. As a result, the stress can be dispersed.

加えて、本発明では、前記折り返し部１３ｂにも補強布１５ａ〜１５ｄを位置させているので、前記応力の分散との相乗効果によってベントホール１４の近傍でエアバッグ１１を構成する基布１２が破れる不具合を防止することができる。   In addition, in the present invention, since the reinforcing cloths 15a to 15d are located also in the folded portion 13b, the base cloth 12 constituting the airbag 11 in the vicinity of the vent hole 14 due to the synergistic effect with the dispersion of the stress. The trouble which is torn can be prevented.

ちなみに、本発明の効果を確認するために、図２に示した構成のエアバッグ１１を展開させた際の展開後の基布の状態を図６（ｃ）に示す。本発明の構成を採用した場合、エアバッグの展開後も、ベントホールの近傍の基布（図６（ｃ）の矢印Ｃで示す箇所）にダメージは見られなかった。   Incidentally, in order to confirm the effect of the present invention, the state of the base fabric after deployment when the airbag 11 having the configuration shown in FIG. 2 is deployed is shown in FIG. When the configuration of the present invention was adopted, no damage was found on the base fabric (the location indicated by arrow C in FIG. 6C) in the vicinity of the vent hole even after the airbag was deployed.

比較として、ただ単に外周縫製の終端部同士を離間させてベントホールを形成したエアバッグ（図４参照）と、ベントホールを形成する外周縫製の終端部同士を折り返しただけで折り返し部に補強布のないエアバッグ（図５参照）について同様の実験を行った。   As a comparison, an airbag (see FIG. 4) in which the outer peripheral sewing end portions are simply separated from each other to form a vent hole and the outer peripheral sewing end portions forming the vent hole are merely folded back to provide a reinforcing cloth on the folded portion. A similar experiment was conducted for an airbag without air (see FIG. 5).

その結果を図６（ａ）（ｂ）に示す。ただ単に外周縫製の終端部同士を離間させてベントホールを形成したエアバッグの場合、エアバッグの展開後、ベントホールの近傍の基布に（図６（ａ）の矢印Ａで示す箇所）、外周縫製の終端部に沿う破断が見られた。   The results are shown in FIGS. 6 (a) and 6 (b). In the case of an airbag in which vent holes are formed by simply separating the end portions of the outer periphery sewing, on the base fabric in the vicinity of the vent holes after deployment of the airbag (location indicated by arrow A in FIG. 6A), Breaks were observed along the end of the peripheral sewing.

また、外周縫製の終端部同士を折り返しただけで折り返し部に補強布の無いエアバッグの場合、エアバッグの展開後、ベントホールの近傍の基布に（図６（ｂ）の矢印Ｂで示す箇所）、外周縫製の終端部に強いテンションが作用して基布が引っ張られた。   Further, in the case of an airbag in which the end portions of the outer periphery sewing are folded back and the folded portion does not have a reinforcing cloth, the airbag is deployed on the base fabric near the vent hole (indicated by an arrow B in FIG. 6B). ), A strong tension was applied to the end of the outer periphery sewing, and the base fabric was pulled.

本発明は上記の例に限らず、各請求項に記載された技術的思想の範疇に含まれるものであれば、適宜実施の形態を変更しても良いことは言うまでもない。   The present invention is not limited to the above examples, and it goes without saying that the embodiments may be appropriately changed as long as they are included in the scope of the technical idea described in each claim.

すなわち以上で述べたサイドエアバッグ装置は、本発明の好ましい例であって、これ以外の実施態様も、各種の方法で実施または遂行できる。特に本願明細書中に限定する主旨の記載がない限り、本発明は添付図面に示した詳細な部品の形状、大きさ、および構成配置等に制約されるものではない。また、本願明細書の中に用いられた表現および用語は、説明を目的としたもので、特に限定される主旨のない限り、それに限定されるものではない。   That is, the side airbag device described above is a preferable example of the present invention, and other embodiments can be implemented or performed by various methods. In particular, the present invention is not limited to the detailed shape, size, configuration, and the like of the components shown in the accompanying drawings unless otherwise specified in the present specification. In addition, expressions and terms used in the present specification are for the purpose of explanation, and are not limited thereto unless specifically limited.

例えば、上記の例では、１枚の基布１２を折り曲げ、その外周を縫製することで袋状のエアバッグ１１を形成しているが、２枚の布パネルの外周を縫製することで袋状のエアバッグを形成するものでも良い。   For example, in the above example, the bag-like airbag 11 is formed by bending one base cloth 12 and sewing the outer periphery thereof, but the bag-like airbag 11 is formed by sewing the outer periphery of two cloth panels. It may be the one that forms the airbag.

また、図２に示したものに替えて、図３に示すように外周縫製１３の終端部１３ａを、布パネル延長部１２ａａ，１２ｂａに位置するようにしてもよい。   Moreover, it may replace with what was shown in FIG. 2, and you may make it the termination | terminus part 13a of the outer periphery sewing 13 be located in cloth panel extension part 12aa, 12ba as shown in FIG.

また、布パネル延長部１２ａａ，１２ｂａの形状も、ベントホール１４が布パネル１２ａ，１２ｂの外周よりエアバッグ１１の内側に引き下がって構成されるものであれば、図１に示したものに限るものではない。   Further, the shape of the fabric panel extension portions 12aa and 12ba is also limited to that shown in FIG. 1 as long as the vent hole 14 is configured to be pulled down from the outer periphery of the fabric panels 12a and 12b to the inside of the airbag 11. is not.

また、上記の例では、補強布１５ａ〜１５ｄの外周形状を基布１２の外周形状と同じ形状にしているが、外周縫製１３の終端部１３ａの折り返し部１３ｂに補強布１５ａ〜１５ｄが位置すれば、同じ形状で無くても良い。   In the above example, the outer peripheral shapes of the reinforcing cloths 15 a to 15 d are the same as the outer peripheral shape of the base cloth 12, but the reinforcing cloths 15 a to 15 d are positioned at the folded portion 13 b of the terminal end portion 13 a of the outer peripheral sewing 13. For example, the shape may not be the same.

また、上記の例ではエアバッグ１１内は一つの空間であるが、乗員の腕部と対応する箇所に前記腕部の押圧を抑制する部分を形成したり、前記空間を適宜小さな空間に分割したものでも良い。   In the above example, the airbag 11 is a single space, but a portion that suppresses pressing of the arm portion is formed at a location corresponding to the arm portion of the occupant, or the space is divided into small spaces as appropriate. Things can be used.

上記本発明のサイドエアバッグ装置は、運転席だけでなく、助手席や後部座席にも適用できることは言うまでもない。   It goes without saying that the side airbag device of the present invention can be applied not only to the driver's seat but also to the passenger seat and the rear seat.

上記の実施例では、自動車に取付けるサイドエアバッグ装置について説明したが、自動車以外に航空機や船舶等の乗物用のサイドエアバッグ装置にも適用可能であり、同様な効果が発揮される。   In the above-described embodiment, the side airbag device attached to the automobile has been described. However, the present invention can be applied to a side airbag apparatus for vehicles such as an aircraft and a ship other than the automobile, and the same effect is exhibited.
