[0033] 第 3図及び第 5図の通り、このハーネス 10hが揷通されている開口 8kの周縁部は、 その外周囲よりも一段低い低所 8tとなっている。この低所 8tの深さは、シール部材 5 0のフランジ部 51の厚みよりも小さい。シール部材 50は、その周回溝 52に該開口 8k の内周縁を係合させ、フランジ部 51を低所 8t内に配置させるようにして該開口 8kに 装着されている。周回溝 52の溝底面におけるシール部材 50の直径は、開口 8kの内 径よりも若干大きくなつており、周回溝 52の溝底面は開口 8kの内周に密着する。  As shown in FIGS. 3 and 5, the peripheral edge of the opening 8k through which the harness 10h is passed is a low place 8t that is one step lower than the outer periphery. The depth of the low portion 8t is smaller than the thickness of the flange portion 51 of the seal member 50. The seal member 50 is attached to the opening 8k so that the inner peripheral edge of the opening 8k is engaged with the circumferential groove 52 and the flange portion 51 is disposed in the low place 8t. The diameter of the seal member 50 at the groove bottom surface of the circumferential groove 52 is slightly larger than the inner diameter of the opening 8k, and the groove bottom surface of the circumferential groove 52 is in close contact with the inner periphery of the opening 8k.
[0034] この乗員拘束装置をシートパン 8に組み付けるには、エアバッグモジュール 10は、 シートパン 8への取り付けに先立ち、エアバッグ 12及びガス発生器 14がそれぞれリテ ーナ 16に連結されると共に、エアバッグ 12が折り畳まれ、該エアバッグ 12の折り畳 み体に包囲体 18が装着された第 4図の状態にまで組み立てられる。なお、ハーネス 10hはガス発生器 14に接続され、エアバッグ 12及び包囲体 18を通って外部に引き 出されている。  [0034] In order to assemble this occupant restraint device to the seat pan 8, the airbag module 10 is connected to the retainer 16 before the airbag 12 and the gas generator 14 are connected to the seat pan 8, respectively. The airbag 12 is folded and assembled to the state of FIG. 4 in which the envelope 18 is attached to the folded body of the airbag 12. The harness 10h is connected to the gas generator 14, and is pulled out through the airbag 12 and the enclosure 18.
[0035] このハーネス 10hには予めシール部材 50が装着されて!、る。  [0035] A seal member 50 is attached to the harness 10h in advance.
[0036] その後、このようにして組み立てられたエアバッグモジュール 10をシートパン 8の収 容部 8d内に配置する。この際、ハーネス 10hを開口 8kに揷通すると共に、シール部 材 50を該開口 8kに内嵌させ、そのフランジ部 51を低所 8t内に配置する。また、各ス タッドボルト 20を、それぞれ対応するボルト揷通孔 8eに揷通し、このスタッドボルト 20 にナット 26を締め込む。これにより、エアバッグモジュール 10がシートパン 8に固設さ れる。 Thereafter, the airbag module 10 assembled in this way is placed in the storage portion 8 d of the seat pan 8. At this time, the harness 10h is passed through the opening 8k, the seal member 50 is fitted into the opening 8k, and the flange 51 is disposed in the low place 8t. Further, each stud bolt 20 is passed through the corresponding bolt insertion hole 8e, and the nut 26 is tightened into the stud bolt 20. As a result, the airbag module 10 is fixed to the seat pan 8.

[0038] このようにして、フランジ部 51が低所 8tに押し付けられると共に、前記のように、シ 一ル部材 50の周回溝 52の溝底面が開口 8kの内周に密着する。これにより、開口 8k を介してエアバッグモジュール 10側へ水や湿気が侵入することが防止される。  In this way, the flange portion 51 is pressed against the lower portion 8t, and the groove bottom surface of the circumferential groove 52 of the seal member 50 is in close contact with the inner periphery of the opening 8k as described above. This prevents water and moisture from entering the airbag module 10 through the opening 8k.
[0039] なお、この実施の形態では、該シール部材 50を挟んだ左右両側で、エアバッグモ ジュール 10がそれぞれスタッドボルト 20によりシートパン 8に固定されているので、該 シール部材 50が略左右均等にシートパン 8とエアバッグモジュール 10の下面とに押 し付けられる。この結果、該シール部材 50によるシール性が良好なものとなる。 [0039] In this embodiment, the airbag module 10 is fixed to the seat pan 8 by the stud bolt 20 on both the left and right sides of the seal member 50, so that the seal member 50 is substantially equally left and right. Press against the seat pan 8 and the lower surface of the airbag module 10. Be trained. As a result, the sealing performance by the seal member 50 is good.
[0040] ただし、シール部材 50の配置はこれに限定されるものではない。例えば、このシー ル部材 50は、各スタッドボルト 20よりもエアバッグモジュール 10の長手方向の端部に 寄った位置に配置されてもよい。また、このシール部材 50は、エアバッグモジュール 10の下面のうちでも特にリテーナ 16の下面と重なる位置に配置されてもよぐこれ以 外の位置(リテーナ 16の下面と重ならな 、位置)に配置されてもょ 、。 However, the arrangement of the seal member 50 is not limited to this. For example, the seal member 50 may be disposed at a position closer to the longitudinal end of the airbag module 10 than the stud bolts 20. In addition, the seal member 50 is located at a position other than the bottom surface of the air bag module 10, particularly at a position that overlaps the bottom surface of the retainer 16 (a position that does not overlap the bottom surface of the retainer 16). It will be placed.
[0041] 上記実施の形態では周回溝 52の溝底面も開口 8kの内周に密着している力 第 8a , 8b図に示すように、周回溝が省略され、フランジ部 51に円筒状の胴部 53が直に連 なり、この胴部 53の直径が開口 8kの内径よりも小さいシール部材 50Aを用いてもよ い。この場合、フランジ部 51が低所 8tに密着することにより、水や湿気の侵入が防止 される。 In the above embodiment, the force with which the groove bottom surface of the circumferential groove 52 is also in close contact with the inner circumference of the opening 8k, as shown in FIGS. 8a and 8b, the circumferential groove is omitted, and the flange 51 has a cylindrical body. The sealing member 50A may be used in which the portion 53 is directly connected and the diameter of the trunk portion 53 is smaller than the inner diameter of the opening 8k. In this case, the intrusion of water or moisture is prevented by the flange 51 being in close contact with the low 8t.
[0042] 第 8a, 8b図のシール部材 50Aは、フランジ部 51が円形である力 第 9a, 9b図のよ うにフランジ部 51が角形のシール部材 50B, 50Cを用いてもよい。なお、胴部は円 筒状でなくてもよぐ第 9b図のように角筒形などの非円形としてもよい。この角筒は四 角形に限定されず、三角形や五角形以上の多角形であってもよい。  The seal member 50A shown in FIGS. 8a and 8b may be a seal member 50B and 50C having a square flange portion 51 as shown in FIGS. 9a and 9b. The body may not be cylindrical, but may be non-circular such as a square cylinder as shown in Fig. 9b. This rectangular tube is not limited to a square, and may be a triangle or a polygon more than a pentagon.
[0043] 本発明では、第 10a, 10b図のように上記のフランジ部のみよりなるシール部材 50 D, 50Eを用いてもよい。  In the present invention, as shown in FIGS. 10a and 10b, seal members 50D and 50E composed only of the flange portion may be used.
[0044] 本発明では、第 11図のように、ハーネス 10hを保護シース 60に揷通し、この保護シ ース 60をシール部材 50Fのハーネス揷通孔 54に揷通してもよい。また、この保護シ ース 60として図示の通り螺旋状又は周回状の溝 61が外周面に周設されたコルゲー トチューブよりなるものを用いてもよ 、。  In the present invention, as shown in FIG. 11, the harness 10h may be threaded through the protective sheath 60, and the protective sheath 60 may be threaded through the harness through hole 54 of the seal member 50F. Further, as the protective sheath 60, a protective sleeve 60 made of a corrugated tube in which spiral or circular grooves 61 are provided on the outer peripheral surface as shown in the figure may be used.
[0045] このシール部材 50Fが前記シール部材 50と異なるのは、ハーネス揷通孔 54の内 周面に突起 55が周設されて 、ると共に、ハーネス揷通孔 54が保護シース 60を揷通 し得るように大径となっている点にあり、その他の構成はシール部材 50と同様である 。このシール部材 50Fも、周回溝 52を開口 8kに内嵌させ、フランジ部 51を開口 8kの 上側に配置させるようにして用いられる。  The seal member 50F is different from the seal member 50 in that the protrusion 55 is provided around the inner peripheral surface of the harness through hole 54, and the harness through hole 54 passes through the protective sheath 60. In other words, the configuration is the same as that of the seal member 50. This seal member 50F is also used so that the circumferential groove 52 is fitted in the opening 8k and the flange portion 51 is disposed above the opening 8k.
[0046] フランジ部 51が低所 8tに押し付けられると共に、この突起 55が溝 61の内面に密着 することにより、水や湿気が貫通孔 54を通って侵入することが防止される。溝 61が周 回溝の場合、突起 55はリング状に周回する。 [0046] The flange portion 51 is pressed against the lower portion 8t, and the protrusion 55 comes into close contact with the inner surface of the groove 61, thereby preventing water and moisture from entering through the through hole 54. Groove 61 goes around In the case of a turning groove, the protrusion 55 circulates in a ring shape.
[0047] 上記実施の形態はいずれも本発明の一例であり、本発明は図示以外の形態をもと りうる。例えば、上記実施の形態ではシール部材の上面にエアバッグモジュール 10 の包囲体 18に押し付けられる構成となっている力 包囲体 18を省略し、エアバッグ がシール部材を押し付ける構成としてもよ 、。 [0047] Each of the above embodiments is an example of the present invention, and the present invention may take forms other than those illustrated. For example, in the above embodiment, the force envelope 18 configured to be pressed against the envelope 18 of the airbag module 10 on the upper surface of the seal member may be omitted, and the airbag may press the seal member.
[0048] また、エアバッグをケーシング内に収容し、このケーシング底面からハーネス 10hを 引き出すようにしてもよぐこの場合には、ケーシング底面がシール部材を上力も押し 付けるようにする。 [0048] Further, the airbag may be accommodated in the casing, and the harness 10h may be pulled out from the bottom surface of the casing. In this case, the bottom surface of the casing presses the sealing member also with an upper force.
[0049] また、上記の各実施の形態では、エアノ ッグをリテーナに連結するのとリテーナをシ ートパンに固定するのを共通のスタッドボルトによって行っている力 エアバッグをリテ ーナに連結するためのスタッドボルトと、リテーナをシートパンに固定するためのスタ ッドボルトとをそれぞれ設けてもょ 、。エアバッグのリテーナヘの連結手段ゃリテーナ のシートパンへの固定手段はスタッドボルト及びナットに限定されるものではない。  [0049] Further, in each of the above-described embodiments, a force is used to connect the air noggles to the retainer and to fix the retainer to the seat pan by a common stud bolt. The air bag is connected to the retainer. There may be a stud bolt for fixing and a stud bolt for fixing the retainer to the seat pan.
