Both the main panel 21 and the sub panel 40 are a sheet-like base fabric.
　メインパネル２１は、帯状のメインパネルの一例であり、例えば、左縁部３４と、右縁部３３と、一対の取り付け端部２６，２７と、中間部３０と、一対の延伸部３１，３２とを有する。 The main panel 21 is an example of a strip-shaped main panel. For example, the left edge portion 34, the right edge portion 33, a pair of attachment end portions 26 and 27, an intermediate portion 30, and a pair of extending portions 31 and 32. And have.
　左縁部３４は、メインパネル２１の幅方向８の一方の側縁部であり、メインパネル２１の幅方向８の第１の側縁部の一例である。右縁部３３は、メインパネル２１の幅方向８の他方の側縁部であり、幅方向８で左縁部３４とは反対側の第２の側縁部の一例である。左縁部３４と右縁部３３は、それぞれ、取り付け端部２６から取り付け端部２７までメインパネル２１の長手方向７に延在する。 The left edge portion 34 is one side edge portion in the width direction 8 of the main panel 21, and is an example of a first side edge portion in the width direction 8 of the main panel 21. The right edge portion 33 is the other side edge portion of the main panel 21 in the width direction 8 and is an example of a second side edge portion on the opposite side of the left edge portion 34 in the width direction 8. The left edge portion 34 and the right edge portion 33 each extend in the longitudinal direction 7 of the main panel 21 from the attachment end portion 26 to the attachment end portion 27.
　取り付け端部２６は、メインパネル２１の長手方向７の一方の先端部である。取り付け端部２７は、メインパネル２１の長手方向７の他方の先端部であり、長手方向７において取り付け端部２６とは反対側の先端部である。例えば、取り付け端部２６は、一対の取り付け孔８６を有し、取り付け端部２７は、一対の取り付け孔８７を有する。 The attachment end portion 26 is one end portion in the longitudinal direction 7 of the main panel 21. The attachment end 27 is the other end portion of the main panel 21 in the longitudinal direction 7, and is the end portion on the opposite side of the attachment end portion 26 in the longitudinal direction 7. For example, the attachment end portion 26 has a pair of attachment holes 86, and the attachment end portion 27 has a pair of attachment holes 87.
　図５の（Ｂ）において、中間部３０は、メインパネル２１の長手方向７の第１の中間部の一例であり、一対の延伸部３１，３２の間に位置する。一対の延伸部３１，３２は、中間部３０の長手方向７の両側に接続され、一方の延伸部３１は、中間部３０から取り付け端部２６に向けて長手方向７に延伸し、他方の延伸部３２は、中間部３０から取り付け端部２７に向けて長手方向７に延伸する。延伸部３１は、インフレータ２のガス噴出部が挿入される取り付け口１１を有する。 5B, the intermediate portion 30 is an example of a first intermediate portion in the longitudinal direction 7 of the main panel 21 and is located between the pair of extending portions 31 and 32. The pair of extending portions 31 and 32 are connected to both sides in the longitudinal direction 7 of the intermediate portion 30, and one extending portion 31 extends in the longitudinal direction 7 from the intermediate portion 30 toward the attachment end portion 26, and the other extending portion The portion 32 extends in the longitudinal direction 7 from the intermediate portion 30 toward the attachment end portion 27. The extending part 31 has an attachment port 11 into which the gas ejection part of the inflator 2 is inserted.
　中間部３０は、メインパネル２１の幅方向８において一対の延伸部３１，３２に比べて幅広であり、中間部３０の幅Ｌ５は、一対の延伸部３１，３２の幅Ｌ６よりも広い。中間部３０は、エアバッグ１０１の膨張展開時に助手席の乗員の頭部を受け止める部位である。したがって、中間部３０が幅方向８において一対の延伸部３１，３２に比べて幅広であることにより、助手席の乗員の頭部を確実に受け止めることができる。 The intermediate portion 30 is wider than the pair of extending portions 31, 32 in the width direction 8 of the main panel 21, and the width L5 of the intermediate portion 30 is wider than the width L6 of the pair of extending portions 31, 32. The intermediate portion 30 is a portion that receives the head of the passenger in the passenger seat when the airbag 101 is inflated and deployed. Therefore, since the intermediate portion 30 is wider than the pair of extending portions 31 and 32 in the width direction 8, the head of the passenger in the passenger seat can be reliably received.
　中間部３０の左縁部３４は、一対の延伸部３１，３２の左縁部３４に対して左方に突出し、中間部３０の右縁部３３は、一対の延伸部３１，３２の右縁部３３に対して右方に突出する。中間部３０の左縁部３４と中間部３０の右縁部３３は、互いに平行な直線部分３６を有し、延伸部３１の左縁部３４と延伸部３１の右縁部３３は、互いに平行な直線部分３７を有し、延伸部３２の左縁部３４と延伸部３２の右縁部３３は、互いに平行な直線部分３８を有する。 The left edge portion 34 of the intermediate portion 30 protrudes leftward with respect to the left edge portion 34 of the pair of extending portions 31 and 32, and the right edge portion 33 of the intermediate portion 30 is the right edge of the pair of extending portions 31 and 32. Projects to the right with respect to the portion 33. The left edge portion 34 of the intermediate portion 30 and the right edge portion 33 of the intermediate portion 30 have linear portions 36 that are parallel to each other, and the left edge portion 34 of the extending portion 31 and the right edge portion 33 of the extending portion 31 are parallel to each other. The left edge portion 34 of the extending portion 32 and the right edge portion 33 of the extending portion 32 have linear portions 38 that are parallel to each other.
　中間部３０は、左縁部３４と右縁部３３の両側に一対の延伸部３１，３２に対して同じ突出量で突出し、幅Ｌ７と幅Ｌ８は互いに等しい。幅Ｌ７は、中心線８１と中間部３０の左縁部３４との最大距離であり、幅Ｌ８は、中心線８１と中間部３０の右縁部３３との最大距離である。中心線８１は、幅Ｌ６を二等分する直線であり、例えば、円形の取り付け口１１の中心８０を通る。 The intermediate portion 30 protrudes on both sides of the left edge portion 34 and the right edge portion 33 with the same protrusion amount with respect to the pair of extending portions 31, 32, and the width L7 and the width L8 are equal to each other. The width L7 is the maximum distance between the center line 81 and the left edge portion 34 of the intermediate portion 30, and the width L8 is the maximum distance between the center line 81 and the right edge portion 33 of the intermediate portion 30. The center line 81 is a straight line that bisects the width L6, and passes through the center 80 of the circular attachment port 11, for example.
　左縁部３４と右縁部３３は、それぞれ、中間部３０と一対の延伸部３１，３２との間に曲線部分３９を有する。曲線部分３９が設けられることにより、中間部３０が一対の延伸部３１，３２よりも幅広であっても、左縁部３４と左パネル２３の外周部８２（図８参照）との接合作業、及び右縁部３３と右パネル２２の外周部８３（図９参照）との接合作業が容易になる。例えば、左縁部３４と右縁部３３のそれぞれについて中間部３０と一対の延伸部３１，３２との間の部分が直角である場合に比べて、縫合等による接合作業が容易になる。 The left edge portion 34 and the right edge portion 33 each have a curved portion 39 between the intermediate portion 30 and the pair of extending portions 31 and 32. By providing the curved portion 39, even if the intermediate portion 30 is wider than the pair of extending portions 31 and 32, the joining operation of the left edge portion 34 and the outer peripheral portion 82 (see FIG. 8) of the left panel 23, And the joining operation | work of the right edge part 33 and the outer peripheral part 83 (refer FIG. 9) of the right panel 22 becomes easy. For example, as compared with the case where each of the left edge portion 34 and the right edge portion 33 has a right angle between the intermediate portion 30 and the pair of extending portions 31 and 32, the joining work by stitching or the like is facilitated.
　サブパネル４０は、中間部３０に接合され、長手方向７の長さがメインパネル２１よりも短いサブパネルの一例である。サブパネル４０の長手方向７の長さＬ１は、メインパネル２１の長手方向７の長さＬ３よりも短く、中間部３０の長手方向７の長さＬ４よりも短い。サブパネル４０の形状は、例えば、サブパネル４０の幅方向８の長さＬ２が長さＬ１よりも長くなるように形成された長円形である。サブパネル４０は、半円状の左外縁部４４と、半円状の右外縁部４３とを有する。 The sub-panel 40 is an example of a sub-panel that is joined to the intermediate portion 30 and has a length in the longitudinal direction 7 shorter than that of the main panel 21. The length L1 of the sub-panel 40 in the longitudinal direction 7 is shorter than the length L3 of the main panel 21 in the longitudinal direction 7 and shorter than the length L4 of the intermediate portion 30 in the longitudinal direction 7. The shape of the sub panel 40 is, for example, an oval formed so that the length L2 in the width direction 8 of the sub panel 40 is longer than the length L1. The sub-panel 40 has a semicircular left outer edge portion 44 and a semicircular right outer edge portion 43.
　図６は、メインパネル２１とサブパネル４０との接合工程及び穴あけ工程の一例を示す図である。図６の（Ａ）は、サブパネル４０とメインパネル２１とが接合部５１で接合され、且つ、孔３５，４２が設けられた形態の一例を示す平面図である。図６の（Ｂ）は、図６の（Ａ）の形態の断面Ｂ－Ｂでの断面図である。 FIG. 6 is a diagram illustrating an example of a joining process and a drilling process between the main panel 21 and the sub-panel 40. FIG. 6A is a plan view showing an example of a form in which the sub panel 40 and the main panel 21 are joined by the joining portion 51 and the holes 35 and 42 are provided. FIG. 6B is a cross-sectional view taken along a cross section BB in the form of FIG.
　サブパネル４０がメインパネル２１に重ね合わされてから、サブパネル４０の中間部４１が線状の接合部５１でメインパネル２１の中間部３０に縫合等により接合される。中間部４１は、サブパネル４０の幅方向８の第２の中間部の一例である。接合部５１は、中間部４１を中間部３０の左縁部３４寄りに接合する環状の第１の接合部の一例である。 After the sub panel 40 is overlaid on the main panel 21, the intermediate part 41 of the sub panel 40 is joined to the intermediate part 30 of the main panel 21 by stitching or the like at the linear joint part 51. The intermediate portion 41 is an example of a second intermediate portion in the width direction 8 of the sub panel 40. The joint portion 51 is an example of an annular first joint portion that joins the intermediate portion 41 closer to the left edge portion 34 of the intermediate portion 30.
　接合部５１の長手方向７の長さＬ１１は、接合部５１の幅方向８の長さＬ１２よりも長い。長さＬ１１が長さＬ１２よりも長いことにより、図２，３，４に示されるように、膨張展開時のサブチャンバ１６を安定的に起立させることが可能となる。接合部５１の形状が長円形である場合、サブチャンバ１６をさらに安定的に起立させることができる。 The length L11 in the longitudinal direction 7 of the joined portion 51 is longer than the length L12 in the width direction 8 of the joined portion 51. Since the length L11 is longer than the length L12, as shown in FIGS. 2, 3, and 4, it is possible to stably stand up the subchamber 16 at the time of expansion and deployment. When the shape of the joint portion 51 is oval, the sub-chamber 16 can be raised more stably.
　孔３５は、メインパネル２１の中間部３０に設けられ、環状の接合部５１の内側に設けられる第１の孔の一例である。孔４２は、サブパネル４０の中間部４１に設けられ、環状の接合部５１の内側に設けられる第２の孔の一例である。孔３５は、中間部３０を貫通し、孔４２は、中間部４１を貫通する。孔３５，４２のそれぞれの数は、一つでもよいし、複数でもよい。孔３５，４２の外形は、それぞれ、円形であるが、円形以外の他の形状でもよい。 The hole 35 is an example of a first hole provided in the intermediate portion 30 of the main panel 21 and provided inside the annular joint portion 51.

The outer shapes of the holes 35 and 42 are each circular, but may be other shapes other than circular.
　孔３５，４２は、中間部３０と中間部４１とが接合部５１で接合された後に形成されることが好ましい。中間部３０と中間部４１とが接合部５１で接合されていることによって、孔３５，４２の形成時に、孔３５，４２の形成位置のずれを抑えることができる。孔３５，４２は、重なり合うように形成されることで、２つの孔３５，４２を１回の穴あけ作業で形成することができ、メインチャンバ１４からサブチャンバ１６へのガスの流通を滑らかにすることができる（図１参照）。 The holes 35 and 42 are preferably formed after the intermediate portion 30 and the intermediate portion 41 are joined by the joint portion 51. Since the intermediate part 30 and the intermediate part 41 are joined by the joint part 51, the formation position of the holes 35 and 42 can be prevented from being shifted when the holes 35 and 42 are formed. The holes 35 and 42 are formed so as to overlap each other, so that the two holes 35 and 42 can be formed by a single drilling operation, and the gas flow from the main chamber 14 to the sub-chamber 16 is made smooth. (See FIG. 1).

Each of the left panel 23 and the right panel 22 is a single base fabric formed in a rounded polygonal sheet.
　左パネル２３は、メインパネル２１の左縁部３４に接合される外周部８２を有し、外周部８２と左縁部３４は、対応する各接合箇所Ａ１，Ｂ１，Ｃ１，Ｄ１で互いに接合される（図７，８参照）。このように、左縁部３４が外周部８２を周回するように左縁部３４と外周部８２とが縫合等により接合される。 The left panel 23 has an outer peripheral portion 82 joined to the left edge portion 34 of the main panel 21, and the outer peripheral portion 82 and the left edge portion 34 are joined to each other at corresponding joint locations A1, B1, C1, D1. (See FIGS. 7 and 8). In this way, the left edge portion 34 and the outer peripheral portion 82 are joined by sewing or the like so that the left edge portion 34 circulates around the outer peripheral portion 82.
　右パネル２２は、メインパネル２１の右縁部３３に接合される外周部８３を有し、外周部８３と右縁部３３は、対応する各接合箇所Ｅ１，Ｆ１，Ｇ１，Ｈ１で互いに接合される（図７，９参照）。このように、右縁部３３が外周部８３を周回するように右縁部３３と外周部８３とが縫合等により接合される。 The right panel 22 has an outer peripheral portion 83 joined to the right edge portion 33 of the main panel 21, and the outer peripheral portion 83 and the right edge portion 33 are joined to each other at corresponding joint locations E1, F1, G1, and H1. (See FIGS. 7 and 9). In this manner, the right edge portion 33 and the outer peripheral portion 83 are joined by stitching or the like so that the right edge portion 33 circulates around the outer peripheral portion 83.
　したがって、上述のように、サブパネル４０とメインパネル２１とを重ね合わせて穴あけ作業を行ってから、サブパネル４０の外縁部同士を接合する簡易な接合作業を行うことで、サブチャンバ１６を容易に形成できる。そして、メインパネル２１の側縁部と一対のサイドパネルの外周部とを接合する簡易な接合作業を行うことで、ガスが流通可能にサブチャンバ１６に接合するメインチャンバ１４を容易に形成できる。このように、メインチャンバ１４とサブチャンバ１６とを有するエアバッグ１０１を簡易に製造することができる。 Therefore, as described above, the sub-panel 16 and the main panel 21 are overlapped to perform the drilling operation, and then the sub-chamber 16 is easily formed by performing a simple bonding operation for bonding the outer edges of the sub-panel 40 to each other. it can.

However, the side surface of the passenger's head can be received by the right side surface 45 of the sub-chamber 16.
　＜エアバッグ１０２の構成＞
　図１０は、膨張展開したエアバッグ１０２の形態の一例を示す左斜視図である。図１１は、膨張展開したエアバッグ１０２の形態の一例を示す右斜視図である。図示のエアバッグ１０２は、助手席が前列右側に位置する場合の助手席用エアバッグの一例である。上述のエアバッグ１０１と同様の構成についての説明は省略する。 <Configuration of Airbag 102>
FIG. 10 is a left perspective view showing an example of the form of the inflated and deployed airbag 102. FIG. 11 is a right perspective view showing an example of the configuration of the inflated and deployed airbag 102. FIG. The illustrated airbag 102 is an example of a passenger seat airbag when the passenger seat is located on the right side of the front row. A description of the same configuration as that of the above-described airbag 101 is omitted.
　図１０，１１に示されるように、エアバッグ１０２は、メインパネル６１と、サブパネル４０と、左パネル９３と、右パネル９２とを備える。左パネル９３と右パネル９２は、車幅方向５に対置する一対のサイドパネルである。エアバッグ１０２は、帯状のメインパネル６１が非対称な点で、対称のメインパネル２１を有する上述のエアバッグ１０１と異なる。 As shown in FIGS. 10 and 11, the airbag 102 includes a main panel 61, a sub panel 40, a left panel 93, and a right panel 92. The left panel 93 and the right panel 92 are a pair of side panels that face each other in the vehicle width direction 5. The airbag 102 is different from the above-described airbag 101 having the symmetric main panel 21 in that the strip-shaped main panel 61 is asymmetric.
　＜エアバッグ１０２の製造方法＞
　次に、エアバッグ１０２の製造方法の一例を説明する。上述のエアバッグ１０２と同様の製造工程についての説明は省略する。 <Method for Manufacturing Airbag 102>
Next, an example of a method for manufacturing the airbag 102 will be described. The description of the manufacturing process similar to that of the above-described airbag 102 is omitted.
　図１２は、サブパネル４０とメインパネル６１とが接合される前の各構成の一例を示す平面図である。図１２の（Ａ）は、サブパネル４０の一例を示す平面図である。図１２の（Ｂ）は、メインパネル６１の一例を示す平面図である。メインパネル６１とサブパネル４０は、いずれも、シート状の一枚の基布である。 FIG. 12 is a plan view showing an example of each configuration before the sub panel 40 and the main panel 61 are joined. FIG. 12A is a plan view showing an example of the sub-panel 40. FIG. 12B is a plan view showing an example of the main panel 61. The main panel 61 and the sub panel 40 are both a sheet-like base fabric.
　メインパネル６１は、帯状のメインパネルの一例であり、例えば、左縁部７４と、右縁部７３と、一対の取り付け端部２６，２７と、中間部７０と、一対の延伸部７１，７２とを有する。 The main panel 61 is an example of a strip-shaped main panel. For example, the left edge portion 74, the right edge portion 73, the pair of attachment end portions 26 and 27, the intermediate portion 70, and the pair of extending portions 71 and 72. And have.
　左縁部７４は、メインパネル６１の幅方向８の一方の側縁部であり、メインパネル６１の幅方向８の第１の側縁部の一例である。右縁部７３は、メインパネル６１の幅方向８の他方の側縁部であり、幅方向８で左縁部７４とは反対側の第２の側縁部の一例である。左縁部７４と右縁部７３は、それぞれ、取り付け端部２６から取り付け端部２７までメインパネル６１の長手方向７に延在する。 The left edge portion 74 is one side edge portion in the width direction 8 of the main panel 61, and is an example of a first side edge portion in the width direction 8 of the main panel 61. The right edge 73 is the other side edge of the main panel 61 in the width direction 8 and is an example of a second side edge opposite to the left edge 74 in the width direction 8. The left edge portion 74 and the right edge portion 73 respectively extend in the longitudinal direction 7 of the main panel 61 from the attachment end portion 26 to the attachment end portion 27.
　中間部７０は、メインパネル６１の長手方向７の第１の中間部の一例であり、一対の延伸部７１，７２の間に位置する。 The intermediate portion 70 is an example of a first intermediate portion in the longitudinal direction 7 of the main panel 61 and is located between the pair of extending portions 71 and 72.
　中間部７０は、メインパネル６１の幅方向８において一対の延伸部７１，７２に比べて幅広であり、中間部７０の幅Ｌ２５は、一対の延伸部７１，７２の幅Ｌ２６よりも大きい。中間部７０は、エアバッグ１０２の膨張展開時に助手席の乗員の頭部を受け止める部位である。したがって、乗員の頭部を受け止め可能なパネルの面積を広げることができる。 The intermediate portion 70 is wider than the pair of extending portions 71 and 72 in the width direction 8 of the main panel 61, and the width L25 of the intermediate portion 70 is larger than the width L26 of the pair of extending portions 71 and 72. The intermediate portion 70 is a portion that receives the head of the passenger in the passenger seat when the airbag 102 is inflated and deployed. Therefore, the area of the panel that can receive the head of the occupant can be increased.
　中間部７０は、左縁部７４側に右縁部７３側に突出するよりも大きく突出し、幅Ｌ２７は幅Ｌ２８よりも大きい。幅Ｌ２７は、中心線８１と中間部７０の左縁部７４との最大距離であり、幅Ｌ２８は、中心線８１と中間部７０の右縁部７３との最大距離である。中間部７０が、左縁部７４側に右縁部７３側に突出するよりも大きく突出することにより、センターコンソール９に向かう乗員の頭部を確実に受け止めることができる。 The intermediate portion 70 protrudes larger than the left edge portion 74 toward the right edge portion 73, and the width L27 is larger than the width L28. The width L27 is the maximum distance between the center line 81 and the left edge portion 74 of the intermediate portion 70, and the width L28 is the maximum distance between the center line 81 and the right edge portion 73 of the intermediate portion 70. The intermediate portion 70 protrudes larger than the left edge portion 74 side protrudes toward the right edge portion 73 side, so that the passenger's head toward the center console 9 can be reliably received.

　図１３は、メインパネル６１とサブパネル４０との接合工程及び穴あけ工程の一例を示す図である。図１３の（Ａ）は、サブパネル４０とメインパネル６１とが接合部５１で接合され、且つ、孔３５，４２が設けられた形態の一例を示す平面図である。図１３の（Ｂ）は、図１３の（Ａ）の形態の断面Ｄ－Ｄでの断面図である。図１３の説明は、図６での説明を援用することにより、省略する。 FIG. 13 is a diagram illustrating an example of a joining process and a drilling process between the main panel 61 and the sub-panel 40. FIG. 13A is a plan view showing an example of a form in which the sub panel 40 and the main panel 61 are joined by the joining portion 51 and the holes 35 and 42 are provided. FIG. 13B is a cross-sectional view taken along the line DD in the form of FIG. The description of FIG. 13 is omitted by using the description of FIG.
　図１４は、サブパネル４０の外縁部同士を接合する工程の一例を示す図である。図１４の（Ａ）は、左外縁部４４と右外縁部４３とが接合部５２で接合された形態の一例を示す平面図である。図１４の（Ｂ）は、図１４の（Ａ）の形態の左側面４６側からの側面図である。図１４の（Ｃ）は、図１４の（Ｃ）の形態の断面Ｅ－Ｅにおける断面図である。図１４の説明は、図７での説明を援用することにより、省略する。 FIG. 14 is a diagram illustrating an example of a process of joining the outer edge portions of the sub-panel 40 to each other. FIG. 14A is a plan view showing an example of a form in which the left outer edge portion 44 and the right outer edge portion 43 are joined by the joint portion 52. FIG. 14B is a side view from the left side 46 side of the configuration of FIG. FIG. 14C is a cross-sectional view taken along a section EE of the form of FIG. The description of FIG. 14 is omitted by using the description of FIG.
　図１５は、左パネル９３の一例を示す平面図である。図１６は、右パネル９２の一例を示す平面図である。左パネル９３は、メインパネル６１の左縁部７４に接合される第１のサイドパネルの一例である。右パネル９２は、メインパネル６１の右縁部７３に接合される第２のサイドパネルの一例である。左パネル９３と右パネル９２は、それぞれ、丸みを帯びた多角形のシート状に形成された一枚の基布である。 FIG. 15 is a plan view showing an example of the left panel 93. FIG. 16 is a plan view showing an example of the right panel 92. The left panel 93 is an example of a first side panel that is joined to the left edge 74 of the main panel 61. The right panel 92 is an example of a second side panel that is joined to the right edge 73 of the main panel 61. Each of the left panel 93 and the right panel 92 is a single base fabric formed in a rounded polygonal sheet shape.
　左パネル９３は、メインパネル６１の左縁部７４に接合される外周部８４を有し、外周部８４と左縁部７４は、対応する各接合箇所Ａ２，Ｂ２，Ｃ２，Ｄ２で互いに接合される（図１４，１５参照）。このように、左縁部７４が外周部８４を周回するように左縁部７４と外周部８４とが縫合等により接合される。つまり、図１０の接合部５３は、左縁部７４が外周部８４を周回するように左縁部７４と外周部８４とを接合する第３の接合部の一例である。 The left panel 93 has an outer peripheral portion 84 joined to the left edge portion 74 of the main panel 61, and the outer peripheral portion 84 and the left edge portion 74 are joined to each other at corresponding joint locations A2, B2, C2, and D2. (See FIGS. 14 and 15). Thus, the left edge portion 74 and the outer peripheral portion 84 are joined by stitching or the like so that the left edge portion 74 circulates around the outer peripheral portion 84. That is, the joint portion 53 in FIG. 10 is an example of a third joint portion that joins the left edge portion 74 and the outer peripheral portion 84 so that the left edge portion 74 circulates around the outer peripheral portion 84.
　右パネル９２は、メインパネル６１の右縁部７３に接合される外周部８５を有し、外周部８５と右縁部７３は、対応する各接合箇所Ｅ２，Ｆ２，Ｇ２，Ｈ２で互いに接合される（図１４，１６参照）。このように、右縁部７３が外周部８５を周回するように右縁部７３と外周部８５とが縫合等により接合される。つまり、図１１の接合部５４は、右縁部７３が外周部８５を周回するように右縁部７３と外周部８５とを接合する第４の接合部の一例である。 The right panel 92 has an outer peripheral portion 85 joined to the right edge portion 73 of the main panel 61, and the outer peripheral portion 85 and the right edge portion 73 are joined to each other at corresponding joint locations E2, F2, G2, and H2. (See FIGS. 14 and 16). Thus, the right edge portion 73 and the outer peripheral portion 85 are joined by stitching or the like so that the right edge portion 73 circulates around the outer peripheral portion 85. That is, the joint portion 54 in FIG. 11 is an example of a fourth joint portion that joins the right edge portion 73 and the outer peripheral portion 85 so that the right edge portion 73 goes around the outer peripheral portion 85.
　メインパネル６１は、中心線８１に関して非対称であり、左縁部７４の長さは、中間部７０が右縁部７３側よりも左縁部７４側に大きく突出しているため、右縁部７３の長さよりも長い。よって、図１５，１６に示されるように、外周部８４の周長は、外周部８５の周長よりも長い。 The main panel 61 is asymmetric with respect to the center line 81, and the length of the left edge portion 74 is such that the intermediate portion 70 protrudes more on the left edge portion 74 side than on the right edge portion 73 side. Longer than the length. Therefore, as shown in FIGS. 15 and 16, the peripheral length of the outer peripheral portion 84 is longer than the peripheral length of the outer peripheral portion 85.
　したがって、上述のエアバッグ１０１と同様、メインチャンバ１４とサブチャンバ１６とを有するエアバッグ１０２を簡易に製造することができる。また、車両がオフセット衝突することにより、乗員の頭部が慣性でセンターコンソール９寄りに斜めに移動しても、膨張展開したエアバッグ１０２は、乗員の顔面をメインパネル６１の中間部７０で受け止めつつ、乗員の頭部の側面をサブチャンバ１６の右側面４５で受け止めできる。 Therefore, similarly to the airbag 101 described above, the airbag 102 having the main chamber 14 and the sub-chamber 16 can be easily manufactured. Further, even when the head of the occupant moves to the center console 9 obliquely due to an offset collision, the inflated airbag 102 receives the occupant's face at the intermediate portion 70 of the main panel 61. However, the side surface of the passenger's head can be received by the right side surface 45 of the sub-chamber 16.
　以上、助手席用エアバッグ及びそれを備えるエアバッグ装置を実施形態により説明したが、本発明は上記実施形態に限定されるものではない。他の実施形態の一部又は全部との組み合わせや置換などの種々の変形及び改良が、本発明の範囲内で可能である。 As described above, the passenger airbag and the airbag apparatus including the passenger airbag have been described according to the embodiment, but the present invention is not limited to the above embodiment. Various modifications and improvements such as combinations and substitutions with some or all of the other embodiments are possible within the scope of the present invention.
　例えば、本実施形態のエアバッグは、助手席が前列左側に位置する場合の助手席用エアバッグに適用されてもよい。 For example, the airbag of the present embodiment may be applied to a passenger seat airbag when the passenger seat is located on the left side of the front row.
　また、上述の実施形態では、サブチャンバは、車幅方向の内側のサイドパネル寄りに設けられることで、センターコンソール９に向かって斜め方向に移動する乗員の頭部を確実に受け止めできる。しかしながら、サブチャンバは、車幅方向の外側のサイドパネル寄りに設けられてもよい。これにより、サブチャンバは、Ａピラーに向かって斜め方向に移動する乗員の頭部を確実に受け止めできる。 In the above-described embodiment, the sub-chamber is provided near the side panel on the inner side in the vehicle width direction, so that the head of the occupant moving in an oblique direction toward the center console 9 can be reliably received. However, the sub-chamber may be provided near the outer side panel in the vehicle width direction. Thereby, the sub-chamber can reliably receive the head of the occupant moving in the oblique direction toward the A pillar.
