In the knee airbag body 2, the pair of bag-side engaging pieces 24 are oriented in the vehicle width direction, and the tip of the extension piece 26 of the bag-side engaging piece 24 is inserted into the engaging hole 36 of the instrument panel-side engaging piece 31. Get closer. The protruding portion 27 of the bag-side engaging piece 24 is inserted and locked on the peripheral edge of the engaging hole 36. Then, the instrument panel opening 3 is closed by the cover body 22 and the extension plate portion 25 of the knee airbag body 2. Thus, the knee airbag mounting structure 1 is completed.

上述した実施例によれば、ニーエアバッグ本体２０が展開した際の反作用によって、バッグ側係合片２４に車両前方側に向かう力が作用した際に、インパネ開口３に設けられた対向板部３２に延出板部２５が当接されることにより、バッグ側係合片２４が車両前方に変位することの抑制を図ることができる。   According to the above-described embodiment, the opposing plate portion provided in the instrument panel opening 3 when the force toward the vehicle front acts on the bag-side engaging piece 24 due to the reaction when the knee airbag body 20 is deployed. The contact of the extension plate portion 25 with the extension 32 can suppress the displacement of the bag-side engagement piece 24 toward the front of the vehicle.

また、インパネ側係合片３１は、対向板部３２（対向部）より車両前方側に設けられて、バッグ側係合片２４を係合させる係合孔３６（係合部）と、対向板部３２と係合孔３６とに連続されて、車両前後方向に延びる外側板部３４（連続部）と、を有している。これによれば、外側板部３４が、カバー部２１に作用する車両前方側に向かう力を効率よく受け止めることにより、より一層、カバー部２１が車両前方に変位することの抑制を図ることができる。   Further, the instrument panel-side engaging piece 31 is provided on the vehicle front side with respect to the opposing plate portion 32 (opposing portion), and has an engaging hole 36 (engaging portion) for engaging the bag-side engaging piece 24 with the opposing plate. An outer plate portion (continuous portion) that is continuous with the portion 32 and the engagement hole 36 and that extends in the vehicle front-rear direction. According to this, since the outer plate portion 34 efficiently receives the force acting on the cover portion 21 toward the vehicle front side, the displacement of the cover portion 21 toward the vehicle front can be further suppressed. .

また、バッグ側係合片２４には、対向板部３２（対向部）のニーエアバッグ本体２０から離れた端部に連続されて、外側板部３４（連続部）のニーエアバッグ本体２０から離れた側の面に対向する対向面２６Ａが設けられている。これによれば、カバー部２１に車両前方側に向かう力が作用して、ティアラインＴが破断してカバー部２１が変位されて、外側板部３４の外面３４Ａに対向面２６Ａが当接した場合には、カバー部２１が車両前方に変位することの抑制を図ることができる。   Further, the bag-side engaging piece 24 is connected to the end of the opposing plate portion 32 (opposing portion) remote from the knee airbag body 20, and is connected to the outer plate portion 34 (continuous portion) from the knee airbag body 20. An opposing surface 26A opposing the surface on the distant side is provided. According to this, a force toward the vehicle front side acts on the cover portion 21, the tear line T is broken, the cover portion 21 is displaced, and the facing surface 26 </ b> A abuts on the outer surface 34 </ b> A of the outer plate portion 34. In this case, it is possible to suppress the cover portion 21 from being displaced forward of the vehicle.

また、カバー本体２２には、車幅方向に連続されるティアラインＴが設けられ、対向板部３２（対向部）は、ティアラインＴの延長線上に交差する方向に延びている。これによれば、ティアラインＴが破断しても、対向板部３２がティアラインＴの延長線上に交差する方向に延びていることで、対向板部３２を、より確実にバッグ側係合片２４の延出板部２５に当接させることができる。   Further, the cover body 22 is provided with a tear line T that is continuous in the vehicle width direction, and the opposing plate portion 32 (opposing portion) extends in a direction crossing an extension of the tear line T. According to this, even if the tear line T is broken, the opposing plate portion 32 extends in a direction intersecting the extension of the tear line T, so that the opposing plate portion 32 can be more reliably attached to the bag-side engaging piece. 24 can be brought into contact with the extension plate portion 25.

また、インパネ側係合片３１には、対向板部３２（対向部）のニーエアバッグ体２側の端部に連続されて、車両前方に延びる内側板部３３（延在部）が設けられている。これによれば、内側板部３３が設けられていることにより、インパネ側係合片３１の剛性の向上を図ることができる。   Further, the instrument panel-side engaging piece 31 is provided with an inner plate portion 33 (extending portion) that extends to the front of the vehicle and is continuous with an end of the opposing plate portion 32 (opposing portion) on the knee airbag body 2 side. ing. According to this, the rigidity of the instrument panel-side engaging piece 31 can be improved by providing the inner plate portion 33.

However, the present invention is not limited to this. As shown in FIGS. 6 and 7, a bolt hole 51 into which a bolt B is inserted is provided at an end of the bag-side engaging piece 24 distant from the cover body 22, and a fastening formed in the instrument panel-side engaging piece 31. The knee airbag body 2 may be attached to the instrument panel opening 3 by being screwed into the hole 52 using a nut N. That is, the knee airbag body 2 may be attached by being bolted to the instrument panel opening 3.

その他、本発明を実施するための最良の構成、方法などは、以上の記載で開示されているが、本発明は、これに限定されるものではない。即ち、本発明は、主に特定の実施例に関して特に図示され、且つ、説明されているが、本発明の技術的思想及び、目的の範囲から逸脱することなく、以上述べた実施例に対し、形状、材質、数量、その他の詳細な構成において、当業者が様々な変形を加えることができるものである。従って、上記に開示した形状、材質などを限定した記載は、本発明の理解を容易にするために例示的に記載したものであり、本発明を限定するものではないから、それらの形状、材質などの限定の一部、もしくは全部の限定を外した部材の名称での記載は、本発明に含まれるものである。   In addition, the best configuration and method for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the present invention has been particularly shown and described with particular reference to particular embodiments, but without departing from the technical spirit and scope of the invention, Those skilled in the art can make various modifications in shape, material, quantity, and other detailed configurations. Therefore, the description of the shapes, materials, and the like disclosed above is merely illustrative for the purpose of facilitating the understanding of the present invention, and does not limit the present invention.
