　前辺３４は左右方向に直線状に延在している。 The front side 34 extends linearly in the left-right direction.
　ボトムパネル３０の前部側には、インフレータ用開口３５が設けられている。該インフレータ用開口３５の周囲には、インフレータ取付用ボルトを挿通させるための小孔３６が複数個（この実施の形態では４個）設けられている。 An inflator opening 35 is provided on the front side of the bottom panel 30. Around the inflator opening 35, a plurality of (four in this embodiment) small holes 36 are provided for inserting the inflator mounting bolts.
　メインパネル１０の上辺１１にトップパネル２０の左辺２２、後辺２１及び右辺２３を縫着する。後辺２１は上辺１１の中央部１１ａに縫着され、左辺２２は左端側部１１ｂに縫着され、右辺２３は右端側部１１ｃに縫着される。 The left side 22, the rear side 21 and the right side 23 of the top panel 20 are sewn on the upper side 11 of the main panel 10. The rear side 21 is sewn to the central portion 11a of the upper side 11, the left side 22 is sewn to the left end side portion 11b, and the right side 23 is sewn to the right end side portion 11c.
　メインパネル１０の下辺１４にボトムパネル３０の後辺３１が縫着され、左辺１２にボトムパネル３０の左辺３２が縫着され、左辺１３にボトムパネル３０の右辺３３が縫着される。 The rear side 31 of the bottom panel 30 is sewn to the lower side 14 of the main panel 10, the left side 32 of the bottom panel 30 is sewn to the left side 12, and the right side 33 of the bottom panel 30 is sewn to the left side 13.
　メインパネル１０は、エアバッグ１の乗員対向面１ｆと左右のサイド面１ｓとを構成し、トップパネル２０はエアバッグ１の上面を構成し、ボトムパネル３０はエアバッグ１の下面を構成する。エアバッグ１の前縁にあっては、メインパネル１０は存在せず、トップパネル２０の前辺２４とボトムパネル３０の前辺３４とが縫着されている。 The main panel 10 constitutes an occupant-facing surface 1 f and left and right side surfaces 1 s of the airbag 1, the top panel 20 constitutes the upper surface of the airbag 1, and the bottom panel 30 constitutes the lower surface of the airbag 1. At the front edge of the airbag 1, the main panel 10 does not exist, and the front side 24 of the top panel 20 and the front side 34 of the bottom panel 30 are sewn.
　図２の符号１０Ｓ、２０Ｓ、３０Ｓは、各パネル１０，２０，３０同士の縫合予定ラインを示している。 Reference numerals 10S, 20S, and 30S in FIG. 2 indicate stitching planned lines between the panels 10, 20, and 30.
　上記のように各パネル１０，２０，３０同士を縫着した後、インフレータ用開口３５を通してエアバッグ１を表裏反転させることにより、縫合代をエアバッグ１内に配置させて製品形態のエアバッグ１とする。 After the panels 10, 20, and 30 are sewn together as described above, the airbag 1 is turned upside down through the inflator opening 35, so that the seam allowance is arranged in the airbag 1 so that the airbag 1 is in the form of a product. And
　このエアバッグ１は、インフレータが取り付けられ、折り畳まれ、箱状のケース５（図３）内に設置され、前記インフレータ取付用ボルトによってケース５に取り付けられる。インパネ２には、エアバッグ１の折り畳み体を覆うようにリッド（図示略）が設けられる。折り畳まれたエアバッグ１と、インフレータと、ケース５とによって助手席用エアバッグ装置が構成される。このリッドはインパネ２の一部として設けられてもよく、インパネ２とは別体の蓋状部材として設けられてもよい。後者の場合、リッドはケース５に連結される。 The airbag 1 is attached with an inflator, folded, installed in a box-like case 5 (FIG. 3), and attached to the case 5 with the inflator mounting bolt. The instrument panel 2 is provided with a lid (not shown) so as to cover the folded body of the airbag 1. The folded airbag 1, inflator, and case 5 constitute a passenger seat airbag device. This lid may be provided as a part of the instrument panel 2 or may be provided as a lid-like member separate from the instrument panel 2. In the latter case, the lid is connected to the case 5.
　インフレータが作動した場合、エアバッグ１はリッドを押し開け、図３の通り、助手席乗員の前方においてインパネ２とウィンドシールド３との間に展開し、該乗員を拘束する。 When the inflator is activated, the airbag 1 pushes open the lid and deploys between the instrument panel 2 and the windshield 3 in front of the passenger on the passenger seat as shown in FIG. 3 to restrain the passenger.
　このエアバッグ１は、各パネル１０，２０，３０に上記長さＬ１１，Ｌ１４，Ｌ２１，Ｌ３１の直線状部が設けられているので、膨張完了状態にあっては、乗員対向面１ｆが図１ａ，１ｂ，３の通り、上下及び左右にわたって平面に近い略平面状となる。この乗員対向面１ｆは、助手席用エアバッグ１の後面視において、略方形となる。このため、このエアバッグ１にあっては、車両の斜突（車両に対し斜め前方から衝撃が加えられる衝突形態。オフセット衝突を含む。）時に乗員が乗員対向面１ｆの左側縁部又は右側縁部に受承される。従って、エアバッグ１の容積を徒に増大させることなく、斜突時に乗員を拘束することができる。 The airbag 1 is provided with the linear portions of the lengths L 11 , L 14 , L 21 , and L 31 on the panels 10, 20, and 30. As shown in FIGS. 1 a, 1 b, and 3, 1 f has a substantially planar shape that is close to a plane in the vertical and horizontal directions. The passenger-facing surface 1f is substantially rectangular in the rear view of the passenger seat airbag 1. For this reason, in the airbag 1, the occupant has a left-side edge or a right-side edge of the occupant-facing surface 1 f when the vehicle obliquely strikes (a collision mode in which an impact is applied obliquely to the vehicle, including offset collision). Accepted by the department. Therefore, it is possible to restrain the occupant at the time of the oblique collision without increasing the volume of the airbag 1.
　助手席用エアバッグ１が、乗員対向面１ｆの後面視が略方形となるように膨張するので、インパネ２とウィンドシールド３との間に膨張したエアバッグは、底面の左右方向中央部だけでなく底面の左辺側及び右辺側もインパネ２に支承されるようになる。これにより、インパネ２とウィンドシールド３との間に膨張した助手席用エアバッグ１の姿勢がより安定したものとなる。 Since the passenger airbag 1 is inflated so that the rear view of the passenger-facing surface 1f is substantially square, the airbag inflated between the instrument panel 2 and the windshield 3 is only at the center in the left-right direction on the bottom. Instead, the left side and the right side of the bottom surface are also supported by the instrument panel 2. Thereby, the posture of the passenger seat airbag 1 inflated between the instrument panel 2 and the windshield 3 becomes more stable.
　図１ａ～３の助手席用エアバッグ１は、左右対称であり、各パネル１０，２０，３０はすべて左右対称であるが、本発明はこれに限定されず、乗員対向面１ｆの左側又は右側が図１のものよりも側方に張り出す構成とされてもよい。 The passenger seat airbag 1 shown in FIGS. 1a to 3 is symmetrical, and all the panels 10, 20, and 30 are symmetrical. However, the present invention is not limited to this, and the left or right side of the occupant facing surface 1f. However, it may be configured to project to the side of FIG.
　図４，５及び図６に示す助手席用エアバッグ１Ａ，１Ｂは、この一例を示している。 The passenger seat airbags 1A and 1B shown in FIGS. 4, 5 and 6 show an example of this.
　図４，５は、図１ａ，２と同様に、助手席用エアバッグ１Ａの斜視図とパネル構成図である。 4 and 5 are a perspective view and a panel configuration diagram of the passenger seat airbag 1A, similarly to FIGS. 1a and 2. FIG.
　この助手席用エアバッグ１Ａは、乗員側において左方へ張り出す張出部７を備えている。張出部７は、助手席用エアバッグ１Ａの上部から下部にまで延在している。 The passenger seat airbag 1A is provided with an overhanging portion 7 projecting leftward on the passenger side. The overhang portion 7 extends from the upper part to the lower part of the passenger seat airbag 1A.
　図５の通り、この助手席用エアバッグ１Ａを構成するトップパネル２０Ａ及びボトムパネル３０Ａでは、後辺２１，３１近傍において左辺２２，３２が左方に突出するように突出部２７，３７が設けられている。 As shown in FIG. 5, the top panel 20A and the bottom panel 30A constituting the passenger seat airbag 1A are provided with protrusions 27 and 37 so that the left sides 22 and 32 protrude to the left in the vicinity of the rear sides 21 and 31. It has been.
　メインパネル１０Ａは、この突出部２７，３７を回り込むように、直線状の中央部１１ａの左半側が図２のものよりも長さＱだけ長いものとなっている。すなわち、図５では、直線状中央部１１ａの長さＬ１１が図２の場合よりもＱだけ長くなっている。 In the main panel 10A, the left half side of the linear central portion 11a is longer than the length in FIG. That is, in FIG. 5, the length L 11 of the linear central portion 11a is longer by Q than the case of FIG.
　この助手席用エアバッグ１Ａは、左側の斜突時に張出部７がステアリング又は左側Ａピラーと乗員との間に膨張する。なお、張出部７の容積は助手席用エアバッグ１Ａの全体の容積に比べて小さいので、インフレータ出力を全く又は殆ど増大させることなく、助手席用エアバッグ１Ａが速やかに膨張完了する。 In the passenger seat airbag 1A, the overhanging portion 7 is inflated between the steering or the left A-pillar and the occupant when the left-side obliquely projects. Since the volume of the overhang portion 7 is smaller than the entire volume of the passenger airbag 1A, the passenger airbag 1A is quickly inflated without increasing or slightly increasing the inflator output.
　図４，５の助手席用エアバッグ１Ａのその他の構成は図１ａ，１ｂ，２の助手席用エアバッグ１と同様であり、同一符号は同一部分を示している。 4 and 5 are the same as those of the passenger seat airbag 1 shown in FIGS. 1a, 1b, and 2, and the same reference numerals denote the same parts.
　図６ａの助手席用エアバッグ１Ｂは、図１ａ，２の助手席用エアバッグ１と同一形状のバッグ本体１’にサブチャンバ４０を取り付けることにより乗員対向面１ｆが側方に張り出すよう構成した助手席用エアバッグ１Ｂを示している。なお、図６ａは助手席用エアバッグ１Ｂの斜視図、図６ｂはバッグ本体１’とサブチャンバ４０とを分離した状態の斜視図、図６ｃは図６ａのＣ－Ｃ線断面図である。 The passenger seat airbag 1B of FIG. 6a is configured such that the occupant facing surface 1f projects laterally by attaching the sub-chamber 40 to the bag body 1 ′ having the same shape as the passenger seat airbag 1 of FIGS. The passenger seat airbag 1B is shown. 6a is a perspective view of the passenger seat airbag 1B, FIG. 6b is a perspective view of the bag body 1 'and the sub-chamber 40 separated from each other, and FIG. 6c is a sectional view taken along the line CC of FIG. 6a.
　バッグ本体１’は、助手席用エアバッグ１の左サイド部後辺に開口１ｈを設けたものであり、その他の構成は助手席用エアバッグ１と同一である。この開口１ｈはメインパネル１０に設けられている。 The bag body 1 ′ is provided with an opening 1 h at the rear side of the left side portion of the passenger seat airbag 1, and the other configuration is the same as that of the passenger seat airbag 1. This opening 1 h is provided in the main panel 10.
　サブチャンバ４０は、外側湾曲面４１と、内側湾曲面４２と、上端面４３と下端面４４とを有している。内側湾曲面４２に開口４５が設けられている。サブチャンバ４０はパネルを縫製することにより製作されたものであり、内側湾曲面４２の周縁部がバッグ本体１’に縫着されている。また、開口１ｈと開口４５とは同一大きさであり、それらの周縁部同士が縫着されている。 The sub-chamber 40 has an outer curved surface 41, an inner curved surface 42, an upper end surface 43 and a lower end surface 44. An opening 45 is provided in the inner curved surface 42. The sub-chamber 40 is manufactured by sewing a panel, and the peripheral edge portion of the inner curved surface 42 is sewn to the bag body 1 '. Moreover, the opening 1h and the opening 45 are the same size, and those peripheral parts are sewn together.
　開口１ｈ、４５は円形であるが、楕円形など他の形状であってもよい。開口１ｈ、４５はそれぞれ２個以上設けられてもよい。助手席用エアバッグ１Ｂのその他の構成は助手席用エアバッグ１と同一であり、同一符号は同一部分を示している。 The openings 1h and 45 are circular, but may be other shapes such as an ellipse. Two or more openings 1h and 45 may be provided. Other configurations of the passenger seat airbag 1B are the same as those of the passenger seat airbag 1, and the same reference numerals denote the same parts.
　この助手席用エアバッグ１Ｂが膨張する場合、まずバッグ本体１’が膨張し、それから開口１ｈ、４５を通ってガスがサブチャンバ４０に流入してサブチャンバ４０が膨張する。サブチャンバ４０は、乗員とステアリング又は左側Ａピラーとの間に膨張する。サブチャンバ４０の容積はバッグ本体１’に比べて小さいので、インフレータの出力を全く又は殆ど増大させることなく、助手席用エアバッグ１Ｂが速やかに膨張完了する。 When the passenger seat airbag 1B is inflated, the bag body 1 'is first inflated, and then the gas flows into the subchamber 40 through the openings 1h and 45, so that the subchamber 40 is inflated. The subchamber 40 expands between the occupant and the steering or left A pillar. Since the volume of the sub-chamber 40 is smaller than that of the bag body 1 ', the passenger seat airbag 1B is quickly inflated without increasing the output of the inflator at all or almost.
　この助手席用エアバッグ１Ｂでは、乗員対向面１ｆからバッグサイド部にわたって１枚のパネル（メインパネル１０）で構成されているので、乗員対向面１ｆの左辺側及び右辺側に上下方向の縫合部がなく、サブチャンバ４０の配置自由度が高い。 In the passenger seat airbag 1B, a single panel (main panel 10) is formed from the occupant facing surface 1f to the bag side portion. Therefore, the stitching portions in the vertical direction are formed on the left side and the right side of the occupant facing surface 1f. And the degree of freedom of arrangement of the sub-chamber 40 is high.
　図４～６ｃでは、張出部を乗員対向面１ｆの左側に配置しているが、右側に配置してもよい。また、張出部を左側及び右側の双方に設けてもよい。 4 to 6c, the overhanging portion is arranged on the left side of the occupant facing surface 1f, but may be arranged on the right side. Moreover, you may provide an overhang | projection part in both the left side and the right side.
　図７，８は、エアバッグ内容積を小さくするために、貫通孔を設けた助手席用エアバッグ１Ｃを示している。なお、図７は図１ａと同様の斜視図、図８は図３と同様の側面図である。 7 and 8 show a passenger seat airbag 1C provided with a through hole in order to reduce the volume of the airbag. 7 is a perspective view similar to FIG. 1a, and FIG. 8 is a side view similar to FIG.
　助手席用エアバッグ１Ｃを構成するトップパネル２０に開口２８が設けられ、ボトムパネル３０に開口３８が設けられ、開口２８，３８をつなぐように筒状パネル８が設けられている。筒状パネル８の上端は開口２８の周縁部に縫着され、筒状パネル８の下端は開口３８の周縁部に縫着されている。筒状パネル８と開口２８，３８とによって、助手席用エアバッグ１Ｃを上下に貫く貫通孔が構成されている。 The top panel 20 constituting the passenger seat airbag 1C is provided with an opening 28, the bottom panel 30 is provided with an opening 38, and the cylindrical panel 8 is provided so as to connect the openings 28 and 38. The upper end of the cylindrical panel 8 is sewn to the peripheral edge of the opening 28, and the lower end of the cylindrical panel 8 is sewn to the peripheral edge of the opening 38. The tubular panel 8 and the openings 28 and 38 form a through-hole penetrating the passenger seat airbag 1C vertically.
　この助手席用エアバッグ１Ｃのその他の構成は助手席用エアバッグ１と同一であり、同一符号は同一部分を示している。 Other configurations of the passenger seat airbag 1C are the same as those of the passenger seat airbag 1, and the same reference numerals denote the same parts.
　この助手席用エアバッグ１Ｃは、貫通孔を設けたことにより、助手席用エアバッグ１に比べて内容積が小さい。そのため、インフレータ出力を小さくしても速やかに膨張完了する。 This passenger seat airbag 1C has a smaller internal volume than the passenger seat airbag 1 due to the provision of through holes. Therefore, even if the inflator output is reduced, the expansion is completed quickly.
　筒状パネル８がトップパネル２０とボトムパネル３０とを連結しているので、助手席用エアバッグ１Ｃは、助手席用エアバッグ１と比較して、自由膨張完了状態における最上位点と最下位点との距離が小さいものとなる。このため、助手席用エアバッグ１Ｃの後面視において上辺と下辺とが左右方向に直線状に長く延在する膨張完了形状となる。 Since the tubular panel 8 connects the top panel 20 and the bottom panel 30, the passenger seat airbag 1 </ b> C is higher than the passenger seat airbag 1 in the free inflation completed state, and the lowest point. The distance from the point is small. For this reason, in the rear view of the passenger seat airbag 1 </ b> C, the upper side and the lower side have an inflated complete shape extending linearly in the left-right direction.
　貫通孔は助手席用エアバッグと左右方向に貫通するように設けられてもよい。２以上の貫通孔が設けられてもよい。 The through hole may be provided so as to penetrate the passenger seat airbag in the left-right direction. Two or more through holes may be provided.
　上記実施の形態は本発明の一例であり、本発明は図示以外の形態とされてもよい。例えば、上記実施の形態では、メインパネル１０，１０Ａが左端側から右端側まで連続した１枚のパネルにて構成されているが、２枚以上のパネルを縫合などにより繋ぎ合わせてメインパネルを構成してもよい。具体的には、メインパネルを中央で分断した形状の左半側パネルと右半側パネルとを繋ぎ合わせたメインパネルを用いてもよい。 The above embodiment is an example of the present invention, and the present invention may be other than illustrated. For example, in the above-described embodiment, the main panels 10 and 10A are configured by a single panel that is continuous from the left end side to the right end side, but two or more panels are joined together by stitching or the like to form the main panel. May be. Specifically, a main panel in which a left half panel and a right half panel having a shape obtained by dividing the main panel at the center may be used.
　本発明では、助手席用エアバッグの膨張完了状態形状を規制するためのテザーを設けてもよい。 In the present invention, a tether for regulating the shape of the inflated state of the passenger airbag may be provided.
　上記実施の形態は本発明の一例であり、本発明は図示以外の形態とされてもよい。
