Description
本発明は、車両内でエアバッグを膨張展開させて、エアバッグにより乗員を保護するエアバッグ装置に関する。
The present invention relates to an airbag device that inflates and deploys an airbag in a vehicle and protects an occupant with the airbag.
車両の緊急時や衝突時に乗員を保護するため、エアバッグ装置が使用されている。エアバッグ装置は、車体に固定されたエアバッグを有し、膨張展開させたエアバッグにより乗員を受け止める。その際、エアバッグは、展開に伴う引っ張りや乗員を受け止めた衝撃により、大きな力を受けることがある。そのため、エアバッグの車体に固定される部分には、高い強度が要求される。
これに関連して、車体に固定される固定布を2枚以上の布から形成して、固定布の強度を確保したエアバッグが知られている(特許文献1参照)。 Airbag devices are used to protect passengers in the event of a vehicle emergency or collision. The airbag device includes an airbag fixed to a vehicle body, and receives an occupant by the airbag that is inflated and deployed. At that time, the airbag may receive a large force due to pulling accompanying deployment and an impact received by the occupant. Therefore, high strength is required for the portion of the airbag fixed to the vehicle body.
In relation to this, there is known an airbag in which the fixing cloth fixed to the vehicle body is formed of two or more cloths and the strength of the fixing cloth is ensured (see Patent Document 1).

The airbag device includes an airbag fixed to a vehicle body, and receives an occupant by the airbag that is inflated and deployed. At that time, the airbag may receive a large force due to pulling accompanying deployment and an impact received by the occupant. Therefore, high strength is required for the portion of the airbag fixed to the vehicle body.
In relation to this, there is known an airbag in which the fixing cloth fixed to the vehicle body is formed of two or more cloths and the strength of the fixing cloth is ensured (see Patent Document 1).
また、エアバッグ装置は、膨張展開させたエアバッグにより乗員を受け止める際、乗員を確実に保護する。そのため、エアバッグは、車体に固定して、車両内の所定範囲に展開させる必要がある。
これに関連して、従来、車体に固定される固定布(固定部)をエアバッグに設けたエアバッグ装置が知られている(特許文献2参照)。 The airbag device reliably protects the occupant when the occupant is received by the inflated and deployed airbag. Therefore, the airbag needs to be fixed to the vehicle body and deployed in a predetermined range in the vehicle.
In relation to this, an airbag apparatus in which a fixed cloth (fixed portion) fixed to a vehicle body is provided in an airbag is known (see Patent Document 2).

In relation to this, an airbag apparatus in which a fixed cloth (fixed portion) fixed to a vehicle body is provided in an airbag is known (see Patent Document 2).
特許文献1のエアバッグ装置では、複数枚の布により固定布を形成するときに、枚数を確認しつつ複数枚の布をエアバッグに取り付ける必要がある。そのため、布の取り扱いと管理に手間がかかり、固定布の形成に要する作業時間が長くなる。また、布の枚数を間違えないよう、布の取り扱いと枚数の確認を慎重に行う必要もある。従って、固定布をエアバッグに形成するための手間と時間が増大する。
In the airbag apparatus of Patent Document 1, when forming a fixed cloth with a plurality of cloths, it is necessary to attach the plurality of cloths to the airbag while checking the number of sheets. Therefore, it takes time to handle and manage the cloth, and the work time required for forming the fixed cloth becomes long. In addition, it is necessary to carefully handle and check the number of cloths so that the number of cloths is not mistaken. Therefore, labor and time for forming the fixed cloth on the airbag are increased.
特許文献2のエアバッグ装置では、固定布を縫製するとともに、固定布の2つの下部を、それぞれ縫製によりエアバッグに取り付ける。固定布は、車体に固定されて、車両内で展開するエアバッグの位置を維持する。しかしながら、従来のエアバッグ装置では、固定布を複数箇所で別個に縫製するため、縫製の工程が多くなる。固定布の縫製時間も長くなるため、縫製の作業効率が低くなる傾向がある。また、固定布は、エアバッグの展開に伴う引っ張りや乗員を受け止めた衝撃により、大きな力を受けることがある。そのため、固定布が外力に耐えられるように、固定布の強度をより高くすることも求められている。
In the airbag device of Patent Document 2, a fixed cloth is sewn and two lower portions of the fixed cloth are attached to the airbag by sewing. The fixed cloth is fixed to the vehicle body and maintains the position of the airbag that is deployed in the vehicle. However, in the conventional airbag apparatus, since the fixed cloth is sewn separately at a plurality of locations, the number of sewing steps increases. Since the sewing time of the fixed cloth also becomes long, the working efficiency of sewing tends to be low. In addition, the fixed cloth may be subjected to a large force due to a pull accompanying the deployment of the airbag or an impact received by the occupant. For this reason, it is also required to increase the strength of the fixed cloth so that the fixed cloth can withstand external force.
本発明は、前記従来の問題に鑑みなされたもので、その目的は、複数の布からなる固定布をエアバッグに簡単に形成できるようにして、固定布の形成に要する作業時間を短縮することである。また、本発明の目的は、エアバッグの固定布の強度を高くしつつ、固定布の縫製のための工程と時間を削減して、縫製の作業効率を向上させることである。

固定布30は、図示のように、固定布30をエアバッグ20に結合する結合縫製部37Aと、固定布30を補強する補強縫製部38Aからなる2種類の縫製部37A、38Aを有し、1つの結合縫製部37Aと1つの補強縫製部38Aで縫製される。即ち、固定布30とエアバッグ20は、重ね合わされて結合縫製部37Aで縫い合わされる。つまり、固定布30とエアバッグ20を結合縫製部37Aで結合することで、エアバッグ20に固定布30が形成される。 FIG. 8 is a view showing a first sewing pattern of the fixed
As shown in the figure, the fixed
結合縫製部37Aは、固定布30を縫製によりエアバッグ20に取り付ける取付縫製部であり、固定布30の基部32を横断して縫製することで固定布30に形成される。この直線状の結合縫製部37Aで、基部32の全体が縫製される。結合縫製部37Aは、固定布30の基部32において固定布30の外まで形成される。
The combined sewing portion 37 </ b> A is an attachment sewing portion for attaching the fixed cloth 30 to the airbag 20 by sewing, and is formed on the fixed cloth 30 by sewing across the base portion 32 of the fixed cloth 30. The entire base portion 32 is sewn by the linear joint sewing portion 37A. The combined sewing portion 37 </ b> A is formed up to the outside of the fixed cloth 30 at the base portion 32 of the fixed cloth 30.
補強縫製部38Aは、折り畳まれた固定布30を縫製して形成される。固定布30は、補強縫製部38Aで縫製され、縫製により補強される。また、補強縫製部38Aは、挿入部33の周り(周辺部分)に形成されて、固定布30の挿入部33を補強し、挿入部33に沿って固定布30を縫製することで固定布30に形成される。補強縫製部38Aは、固定布30の挿入部33を囲む環状(図8では矩形状)に形成される。固定布30は、補強縫製部38Aで矩形状に縫い合わされ、補強縫製部38Aにより、複数の布が一体化して補強される。補強縫製部38Aは、挿入部33の周辺部分を補強し、挿入部33の周りの強度を高くする。
The reinforcing sewing portion 38A is formed by sewing the fixed cloth 30 that is folded. The fixed cloth 30 is sewed by the reinforcement sewing portion 38A and reinforced by sewing. The reinforcing sewing portion 38 </ b> A is formed around (the peripheral portion) around the insertion portion 33, reinforces the insertion portion 33 of the fixed cloth 30, and sewes the fixed cloth 30 along the insertion portion 33 to fix the fixed cloth 30. Formed. The reinforcing sewing portion 38 </ b> A is formed in an annular shape (rectangular shape in FIG. 8) surrounding the insertion portion 33 of the fixed cloth 30. The fixed cloth 30 is sewn into a rectangular shape at the reinforcement sewing portion 38A, and the plurality of cloths are integrated and reinforced by the reinforcement sewing portion 38A. The reinforcement sewing portion 38 </ b> A reinforces the peripheral portion of the insertion portion 33 and increases the strength around the insertion portion 33.
第1の縫製パターンでは、2つの縫製部37A、38Aは、固定布30内で離して形成される。即ち、縫製部37A、38Aは、互いに独立しており、固定布30に別個に形成される。固定布30は2回縫製される。これに対し、第2の縫製パターンでは、固定布30は1回だけ縫製される。
In the first sewing pattern, the two sewing portions 37 </ b> A and 38 </ b> A are formed apart in the fixed cloth 30. That is, the sewing portions 37 </ b> A and 38 </ b> A are independent from each other and are formed separately on the fixed cloth 30. The fixed cloth 30 is sewn twice. On the other hand, in the second sewing pattern, the fixed cloth 30 is sewn only once.
図9は、固定布30の第2の縫製パターンを示す図である。図9Aは、縫製後の固定布30を示す図である。図9B、図9Cは、固定布30の縫製過程を示す図である。
第2の縫製パターンの縫製部37B、38Bは、基本的に、第1の縫製パターンの縫製部37A、38Aと同じ縫製部である。ただし、第2の縫製パターンでは、図示のように、結合縫製部37Bと補強縫製部38Bを繋げて、一度の縫製により連続して形成する。そのため、縫製部37B、38Bの全体の形状を、一筆で書ける形状に設定する。結合縫製部37Bと補強縫製部38Bは、接する部分、又は、重複する部分を有する。 FIG. 9 is a diagram illustrating a second sewing pattern of the fixedcloth 30. FIG. 9A is a diagram showing the fixed cloth 30 after sewing. 9B and 9C are diagrams illustrating a sewing process of the fixed cloth 30. FIG.
The sewing parts 37B and 38B of the second sewing pattern are basically the same sewing parts as the sewing parts 37A and 38A of the first sewing pattern. However, in the second sewing pattern, as shown in the figure, the joint sewing portion 37B and the reinforcement sewing portion 38B are connected and formed continuously by one sewing. Therefore, the entire shape of the sewing portions 37B and 38B is set to a shape that can be written with a single stroke. The combined sewing portion 37B and the reinforcing sewing portion 38B have a contacting portion or an overlapping portion.
第2の縫製パターンの縫製部37B、38Bは、基本的に、第1の縫製パターンの縫製部37A、38Aと同じ縫製部である。ただし、第2の縫製パターンでは、図示のように、結合縫製部37Bと補強縫製部38Bを繋げて、一度の縫製により連続して形成する。そのため、縫製部37B、38Bの全体の形状を、一筆で書ける形状に設定する。結合縫製部37Bと補強縫製部38Bは、接する部分、又は、重複する部分を有する。 FIG. 9 is a diagram illustrating a second sewing pattern of the fixed
The
第2の縫製パターンでは、縫製部37B、38Bの直線状部分が、基部32で同じ位置に設けられる。補強縫製部38Bは、結合縫製部37Bの中間部分に重なるように形成される。固定布30の縫製時には、縫製部37B、38Bの全体を、一筆書きのように連続して縫製する。その際、まず、結合縫製部37B(図9B参照)の一端から縫製を開始して結合縫製部37Bを所定位置まで形成したときに、縫製の方向を変更して、縫製する部分を、結合縫製部37Bから補強縫製部38Bに変更する。また、固定布30を、挿入部33を囲むように矩形状に縫製して、補強縫製部38B(図9C参照)を形成する。続いて、結合縫製部37Bの他端まで縫製して、縫製を終了する。
In the second sewing pattern, the linear portions of the sewing portions 37B and 38B are provided at the same position on the base portion 32. The reinforcing sewing portion 38B is formed so as to overlap the intermediate portion of the combined sewing portion 37B. At the time of sewing the fixed cloth 30, the entire sewing portions 37B and 38B are continuously sewn as in a single stroke. At that time, first, when sewing is started from one end of the combined sewing portion 37B (see FIG. 9B) and the combined sewing portion 37B is formed up to a predetermined position, the sewing direction is changed and the portion to be sewn is connected to the combined sewing portion. The portion 37B is changed to the reinforcement sewing portion 38B. Further, the fixed cloth 30 is sewn in a rectangular shape so as to surround the insertion portion 33 to form a reinforcing sewing portion 38B (see FIG. 9C). Subsequently, sewing is performed to the other end of the combined sewing portion 37B, and the sewing is finished.
第2の縫製パターンでは、結合縫製部37Bを途中まで形成した後、補強縫製部38Bの全体を形成し、続いて、結合縫製部37Bの残りの部分を形成する。固定布30には、直線状の結合縫製部37Bと矩形状の補強縫製部38Bが1回の縫製により連続して形成される。これにより、固定布30とエアバッグ20が縫い合わされ、固定布30がエアバッグ20に取り付けられる。補強縫製部38Bは、挿入部33の周りに形成され、挿入部33の周りで固定布30を補強する。また、固定布30が、結合した複数枚の布により形成されてエアバッグ20に設けられる。その後、固定部材10(図4参照)が固定布30に取り付けられる。固定布30は、エアバッグ20に取り付けられた後、固定部材10により車体に固定される。
In the second sewing pattern, after forming the combined sewing portion 37B halfway, the entire reinforcing sewing portion 38B is formed, and then the remaining portion of the combined sewing portion 37B is formed. On the fixed cloth 30, a linear joint sewing portion 37B and a rectangular reinforcement sewing portion 38B are continuously formed by one sewing. Thereby, the fixed cloth 30 and the airbag 20 are stitched together, and the fixed cloth 30 is attached to the airbag 20. The reinforcing sewing portion 38 </ b> B is formed around the insertion portion 33 and reinforces the fixed cloth 30 around the insertion portion 33. Further, the fixed cloth 30 is formed by a plurality of combined cloths and provided on the airbag 20. Thereafter, the fixing member 10 (see FIG. 4) is attached to the fixing cloth 30. The fixed cloth 30 is fixed to the vehicle body by the fixing member 10 after being attached to the airbag 20.
以上説明したように、本実施形態では、固定布30を所定の複数回折り畳んでエアバッグ20に結合するため、固定布30の取り扱いと管理が容易である。固定布30は所定の複数回折り畳むだけでよいため、固定布30の枚数を確認する手間も削減できる。また、複数の布からなる固定布30を、エアバッグ20に簡単に形成できる。固定布30の枚数を間違えるのを防止できるため、固定布30に必要な強度を確保できる。固定布30の形成にかかる手間を削減できるため、固定布30の形成に要する作業時間を短縮できる。
As described above, in this embodiment, the fixed cloth 30 is folded in a predetermined plurality of times and coupled to the airbag 20, so that the fixed cloth 30 can be easily handled and managed. Since the fixed cloth 30 only needs to be folded a predetermined number of times, it is possible to reduce the trouble of checking the number of the fixed cloths 30. Moreover, the fixed cloth 30 made of a plurality of cloths can be easily formed on the airbag 20. Since it is possible to prevent the number of the fixing cloths 30 from being mistaken, the strength necessary for the fixing cloth 30 can be ensured. Since the labor required for forming the fixed cloth 30 can be reduced, the work time required for forming the fixed cloth 30 can be shortened.
固定布30を複数の折り返し線L1~L3で順に折り返すことで、固定布30を正確に折り畳むことができる。スリット47を固定布30の折り目の位置に形成したため、固定布30を、容易かつ正確に折り畳むことができる。2つの縫製部37B、38Bを連続して形成するときには、縫製部37B、38Bの縫製を途切れさせずに1工程で行うことができる。その結果、縫製のための工程と時間を削減できるため、縫製の作業効率を向上できる。
The fixed cloth 30 can be folded accurately by sequentially folding the fixed cloth 30 along a plurality of folding lines L1 to L3. Since the slit 47 is formed at the fold position of the fixed cloth 30, the fixed cloth 30 can be easily and accurately folded. When the two sewing parts 37B and 38B are formed continuously, the sewing of the sewing parts 37B and 38B can be performed in one step without interruption. As a result, since the process and time for sewing can be reduced, the work efficiency of sewing can be improved.
固定布30を縫製によりエアバッグ20に結合するため、固定布30をエアバッグ20に簡単に結合できる。固定布30とエアバッグ20を高い強度で結合することもできる。補強縫製部38(38A、38B)により固定布30を補強するため、固定布30の強度を高くできる。固定布30の複数の布は、外力を単独で受けずに、共同して外力を受ける。その結果、固定布30は、外力に対する強度が高くなり、破れ難くなる。挿入部33の周りに形成した補強縫製部38により挿入部33を補強するときには、挿入部33の周辺部分の強度を高くできる。これにより、固定布30が挿入部33の周りで破れ難くなるため、固定布30が固定部材10から外れるのを防止できる。補強縫製部38を、挿入部33を囲んで形成するときには、挿入部33の周りの全体を補強できる。
Since the fixed cloth 30 is coupled to the airbag 20 by sewing, the fixed cloth 30 can be easily coupled to the airbag 20. The fixed cloth 30 and the airbag 20 can be combined with high strength. Since the fixed cloth 30 is reinforced by the reinforcing sewing portions 38 (38A, 38B), the strength of the fixed cloth 30 can be increased. The plurality of cloths of the fixed cloth 30 receive external force jointly without receiving external force alone. As a result, the fixed cloth 30 has high strength against external force and is not easily torn. When the insertion portion 33 is reinforced by the reinforcing sewing portion 38 formed around the insertion portion 33, the strength of the peripheral portion of the insertion portion 33 can be increased. Thereby, since the fixed cloth 30 is difficult to be broken around the insertion portion 33, it is possible to prevent the fixed cloth 30 from being detached from the fixed member 10. When the reinforcing sewing portion 38 is formed so as to surround the insertion portion 33, the entire area around the insertion portion 33 can be reinforced.
結合縫製部37(37A、37B)(図8、図9参照)を固定布30の基部32に形成するときには、固定布30を基部32においてエアバッグ20にしっかりと取り付けることができる。
When the joint sewing portion 37 (37A, 37B) (see FIGS. 8 and 9) is formed on the base 32 of the fixed cloth 30, the fixed cloth 30 can be firmly attached to the airbag 20 at the base 32.
なお、固定布30内で、凹部35の底は、負荷が掛かり易い部分であり、結合縫製部37は、少なくとも2つの凹部35の底の下方部間に渡って形成する必要がある。即ち、結合縫製部37は、凹部35の底の下方部間に渡って形成されていればよく、凹部35の底の下方部よりも外側には形成しなくてもよい。ただし、結合縫製部37は、固定布30への負荷に確実に対処するため、上記のように形成するのが好ましい。
In addition, in the fixed cloth 30, the bottom of the recessed part 35 is a part where load is easily applied, and the joint sewing part 37 needs to be formed between the lower parts of the bottoms of at least two recessed parts 35. In other words, the combined sewing portion 37 only needs to be formed between the lower portions of the bottom of the recess 35, and may not be formed outside the lower portion of the bottom of the recess 35. However, the combined sewing portion 37 is preferably formed as described above in order to reliably cope with the load on the fixed cloth 30.
固定布30の凹部35は、固定布30の突出部31が固定部材10により折り曲げられる際に、突出部31を折り曲げ易くするために設けられている。従って、突出部31の折り曲げ易さが問題とならないときには、固定布30に凹部35を設けなくてもよい。この場合には、例えば、突出部31と基部32の間の角部を曲線状に形成して、突出部31と基部32を曲線部で接続する。また、挿入部33は、結合部28の窪み28A(図5参照)の外に配置するようにしてもよい。固定布30に凹部35がなく、かつ、挿入部33を窪み28Aの外に配置するときには、窪み28Aが不要になる。そのため、窪み28Aを結合部28に形成しなくてもよい。
The concave portion 35 of the fixed cloth 30 is provided to facilitate bending of the protruding portion 31 when the protruding portion 31 of the fixed cloth 30 is bent by the fixing member 10. Accordingly, when the ease of bending the protruding portion 31 does not matter, the recessed portion 35 may not be provided in the fixed cloth 30. In this case, for example, the corner between the protruding portion 31 and the base portion 32 is formed in a curved shape, and the protruding portion 31 and the base portion 32 are connected by the curved portion. Further, the insertion portion 33 may be disposed outside the recess 28A (see FIG. 5) of the coupling portion 28. When the fixing cloth 30 has no recess 35 and the insertion portion 33 is disposed outside the recess 28A, the recess 28A is not necessary. Therefore, the recess 28 </ b> A does not need to be formed in the coupling portion 28.
固定布30は、上記した折り畳みの仕方に限定されず、他の仕方で折り畳むようにしてもよい。固定布30は、折り畳んだ後に複数枚の重なり合う布からなるように形成すればよい。固定布30は、エアバッグ20の両面に同じ枚数ずつ配置してもよく、エアバッグ20の各面で異なる枚数になるように配置してもよい。固定布30は、エアバッグ20の一方の面のみに配置してもよい。結合縫製部37は、直線状以外の形状(例えば、曲線状や波状)に形成してもよい。補強縫製部38は、矩形状以外の形状(例えば、円形状や多角形状)に形成してもよい。次に、他の実施形態の固定布について説明する。
The fixed cloth 30 is not limited to the above folding method, but may be folded in other ways. The fixed cloth 30 may be formed of a plurality of overlapping cloths after being folded. The same number of the fixing cloths 30 may be arranged on both surfaces of the airbag 20 or may be arranged so that the number of the fixing fabrics 30 is different on each surface of the airbag 20. The fixed cloth 30 may be disposed only on one surface of the airbag 20. The joint sewing portion 37 may be formed in a shape other than a straight shape (for example, a curved shape or a wave shape). The reinforcing sewing portion 38 may be formed in a shape other than a rectangular shape (for example, a circular shape or a polygonal shape). Next, a fixed fabric according to another embodiment will be described.

図10に示す固定布50は、挿入部33の形状のみが上記した固定布30と相違し、固定布50の挿入部33は、所定幅のスリットからなる。固定布50は、折り返し線L1~L3で折り畳んで、エアバッグ20に結合する。 10 and 11 are diagrams showing fixed fabrics 50 and 51 according to another embodiment. FIG. 10A and FIG. 11A are development views showing the fixed fabrics 50 and 51 before folding. FIG. 10B and FIG. 11B are diagrams showing the fixed fabrics 50 and 51 after being folded.
The fixedcloth 50 shown in FIG. 10 is different from the above-described fixed cloth 30 only in the shape of the insertion portion 33, and the insertion portion 33 of the fixed cloth 50 includes a slit having a predetermined width. The fixed cloth 50 is folded at the folding lines L1 to L3 and coupled to the airbag 20.
図10に示す固定布50は、挿入部33の形状のみが上記した固定布30と相違し、固定布50の挿入部33は、所定幅のスリットからなる。固定布50は、折り返し線L1~L3で折り畳んで、エアバッグ20に結合する。 10 and 11 are diagrams showing fixed

図11に示す固定布51は、スリット状の挿入部33に替えて、円形孔からなる挿入部39を有する。固定布51は、挿入部39を除いて、上記した固定布30と同様に構成されている。固定布51の挿入部39は、ボルト等の固定部材(図示せず)が挿入される固定孔である。固定布51は、折り返し線L1~L3で折り畳んで、エアバッグ20に結合され、挿入部39に挿入された固定部材により車体に固定される。
11 has an insertion portion 39 made of a circular hole in place of the slit-like insertion portion 33. The fixed cloth 51 is configured in the same manner as the fixed cloth 30 described above except for the insertion portion 39. The insertion portion 39 of the fixing cloth 51 is a fixing hole into which a fixing member (not shown) such as a bolt is inserted. The fixed cloth 51 is folded along the folding lines L1 to L3, coupled to the airbag 20, and fixed to the vehicle body by a fixing member inserted into the insertion portion 39.
図12、図13は、固定布51の2つの縫製パターンを示す図である。
図12に示す縫製パターンでは、上記した固定布30(図9参照)と同様に、結合縫製部52Aと補強縫製部53Aを、一続きに繋げて、一度の縫製により連続して形成する。固定布51は、結合縫製部52Aと補強縫製部53Aで連続して縫い合わされる。その際、縫製(図12A参照)を結合縫製部52Aの一端から開始し、結合縫製部52Aを所定位置まで形成した後、挿入部39の全体を囲んで縫製する。これにより、環状の補強縫製部53A(図12B参照)を、挿入部39を囲むように挿入部39の周りに形成する。続いて、結合縫製部52Aの他端まで縫製して縫製を終了する。結合縫製部52Aは、基部32を横断せずに、固定布51内に形成される。 12 and 13 are diagrams showing two sewing patterns of the fixedcloth 51. FIG.
In the sewing pattern shown in FIG. 12, similarly to the above-described fixed cloth 30 (see FIG. 9), the combinedsewing portion 52A and the reinforcing sewing portion 53A are connected together and continuously formed by one-time sewing. The fixed cloth 51 is continuously sewn by the combined sewing portion 52A and the reinforcing sewing portion 53A. At that time, sewing (see FIG. 12A) is started from one end of the combined sewing portion 52A, and after forming the combined sewing portion 52A to a predetermined position, the entire insertion portion 39 is surrounded and sewn. Thus, an annular reinforcing sewing portion 53A (see FIG. 12B) is formed around the insertion portion 39 so as to surround the insertion portion 39. Subsequently, the sewing is finished by sewing up to the other end of the combined sewing portion 52A. The combined sewing portion 52A is formed in the fixed cloth 51 without traversing the base portion 32.
図12に示す縫製パターンでは、上記した固定布30(図9参照)と同様に、結合縫製部52Aと補強縫製部53Aを、一続きに繋げて、一度の縫製により連続して形成する。固定布51は、結合縫製部52Aと補強縫製部53Aで連続して縫い合わされる。その際、縫製(図12A参照)を結合縫製部52Aの一端から開始し、結合縫製部52Aを所定位置まで形成した後、挿入部39の全体を囲んで縫製する。これにより、環状の補強縫製部53A(図12B参照)を、挿入部39を囲むように挿入部39の周りに形成する。続いて、結合縫製部52Aの他端まで縫製して縫製を終了する。結合縫製部52Aは、基部32を横断せずに、固定布51内に形成される。 12 and 13 are diagrams showing two sewing patterns of the fixed
In the sewing pattern shown in FIG. 12, similarly to the above-described fixed cloth 30 (see FIG. 9), the combined
図13に示す縫製パターンでも、結合縫製部52Bと補強縫製部53Bを連続して形成する。ただし、補強縫製部53Bは、挿入部39の一部(ここでは下半分)を囲むように挿入部39の周りに形成する。補強縫製部53Bは、挿入部39の一部に沿って形成されて挿入部39の一部を囲み、挿入部39の周りの一部を補強する。この補強縫製部53Bのように、固定布の補強縫製部は、固定布の補強すべき部分に応じて様々な形状と位置に形成される。
In the sewing pattern shown in Fig. 13, the combined sewing portion 52B and the reinforcing sewing portion 53B are continuously formed. However, the reinforcing sewing portion 53B is formed around the insertion portion 39 so as to surround a part of the insertion portion 39 (here, the lower half). The reinforcing sewing portion 53 </ b> B is formed along a part of the insertion portion 39, surrounds a portion of the insertion portion 39, and reinforces a portion around the insertion portion 39. Like this reinforcement sewing part 53B, the reinforcement sewing part of a fixed cloth is formed in various shapes and positions according to the part which should be reinforced of a fixed cloth.

図14に示す固定布54は、凹部35と貫通孔36を有さない。固定布54は、凹部35と貫通孔36以外は、上記した固定布51と同様に構成されている。固定布54は、縁を揃えて折り畳まれ、固定布54とエアバッグ20は、縁を揃えて重ね合わされる。 FIG. 14 is a diagram illustrating a fixedcloth 54 that is partially different from the fixed cloth 51 illustrated in FIG. 11. FIG. 14A is a development view showing the fixed cloth 54 before folding. FIG. 14B is a diagram illustrating the fixed fabric 54 after being folded.
The fixedcloth 54 shown in FIG. 14 does not have the concave portion 35 and the through hole 36. The fixed cloth 54 is configured in the same manner as the above-described fixed cloth 51 except for the concave portion 35 and the through hole 36. The fixed cloth 54 is folded with the edges aligned, and the fixed cloth 54 and the airbag 20 are overlapped with the edges aligned.

次に、保護布を設けたエアバッグ20について説明する。保護布は、固定部材10(図3、図4参照)とエアバッグ20の間に配置されて、固定部材10からエアバッグ20を保護する。エアバッグ20には、上記した固定布30(図5~図7参照)に加えて、保護布が取り付けられる。
Next, the airbag 20 provided with a protective cloth will be described. The protective cloth is disposed between the fixing member 10 (see FIGS. 3 and 4) and the airbag 20 to protect the airbag 20 from the fixing member 10. A protective cloth is attached to the airbag 20 in addition to the above-described fixed cloth 30 (see FIGS. 5 to 7).
図15は、保護布60を示す図である。
保護布60は、図示のように、エアバッグ20を保護する保護部61と、エアバッグ20へ結合される結合部(結合端)62からなる。保護部61は、矩形状をなし、結合部62と一体に形成されている。結合部62は、固定布30の固定ピース41~46及び折り畳んだ固定布30と同じ形状に形成されている。従って、結合部62は、挿入部33Aと、凹部35Aと、貫通孔36Aとを有する。結合部62は、固定布30のエアバッグ20への結合と同時に、エアバッグ20に結合される。これにより、保護布60がエアバッグ20に取り付けられる。 FIG. 15 is a diagram showing theprotective cloth 60.
As shown in the figure, theprotective cloth 60 includes a protective portion 61 that protects the airbag 20 and a coupling portion (coupling end) 62 coupled to the airbag 20. The protection part 61 has a rectangular shape and is formed integrally with the coupling part 62. The coupling portion 62 is formed in the same shape as the fixed pieces 41 to 46 of the fixed cloth 30 and the folded fixed cloth 30. Accordingly, the coupling portion 62 includes the insertion portion 33A, the concave portion 35A, and the through hole 36A. The coupling portion 62 is coupled to the airbag 20 simultaneously with the coupling of the fixed cloth 30 to the airbag 20. Thereby, the protective cloth 60 is attached to the airbag 20.
