ところで、車両衝突時に、前方に投げ出される乗員からの大荷重がシートベルト装置のベルトアンカー部に入るが、その際、アンカー取付部周辺が変形して前方へ変位すると、乗員拘束力が低下し乗員障害値が悪化することになる。その防止策として、特許文献１，２に示すように、ベルト引張方向にリンフォースを内蔵したり、あるいはビードを延設したりして対応しているが、専用のリンフォースやビード等を設定すると、コストや重量が嵩み、生産性も悪化する。したがって、安価に効果的に衝突時のベルトアンカーの変位を抑えたいという要望がある。   By the way, at the time of a vehicle collision, a large load from an occupant thrown forward enters the belt anchor portion of the seat belt device. At this time, if the area around the anchor attachment portion is deformed and displaced forward, the occupant restraining force is reduced and the occupant restrains. The fault value will be worse. As measures to prevent this, as shown in Patent Documents 1 and 2, a reinforcement is built in the belt pulling direction or a bead is extended to cope with this, but a dedicated reinforcement or bead is set. Then, cost and weight increase, and productivity also deteriorates. Therefore, there is a demand for inexpensively and effectively suppressing displacement of the belt anchor at the time of collision.

ところで、車体の側壁パネル上に設置されるベルトアンカーの上方近傍には、カーテンシールドエアバッグ（ＣＳＡ）装置が設けられている。このカーテンシールドエアバッグ装置は、車両の側面衝突時等に所定値以上の加速度を検出すると、車体の内部側面にあるピラーやドアのドアガラスとシート座席に座った乗員との間を遮るように、ドア開口部の上縁から下向きにカーテン状にエアバッグが展開する。   By the way, a curtain shield airbag (CSA) device is provided near the upper part of the belt anchor installed on the side wall panel of the vehicle body. This curtain shield airbag device, when detecting acceleration equal to or higher than a predetermined value at the time of a side collision of the vehicle, blocks the gap between the occupant sitting on the seat and the pillar or door glass on the inner side of the vehicle body. Then, the airbag is deployed in a curtain shape downward from the upper edge of the door opening.

本発明者は、このカーテンシールドエアバッグ装置が車体の側壁のサイドインナパネルに取り付けられているので、その取付部を利用して、その構造を工夫することで、安価かつ効果的に衝突時のベルトアンカーの変位を抑える車両構造を提供することに着眼し、本発明を完成するに至った。   The present inventor has found that the curtain shield airbag device is attached to the side inner panel on the side wall of the vehicle body, and by using the attachment portion to devise its structure, the curtain shield airbag device can be inexpensively and effectively used in a collision. The present invention has been completed by focusing on providing a vehicle structure that suppresses the displacement of the belt anchor.

すなわち、本発明の車両構造は、車体の側壁パネルの車室内側にシートベルト装置のベルトアンカーが設置され、前記ベルトアンカーの上方にカーテンシールドエアバッグ装置が設けられ、前記側壁パネルのベルトアンカー設置部の直上近傍に、カーテンシールドエアバッグ装置を取付けるための取付用段部が形成され、前記段部は、前記ベルトアンカーの直上近傍で、車両の前突時のベルト引張方向と略同方向に延設されていることを特徴とする。   That is, in the vehicle structure of the present invention, the belt anchor of the seat belt device is installed on the vehicle cabin side of the side wall panel of the vehicle body, the curtain shield airbag device is provided above the belt anchor, and the belt anchor installation of the side wall panel is provided. A mounting step for mounting the curtain shield airbag device is formed in the vicinity immediately above the section, and the step is provided in the vicinity of directly above the belt anchor and in substantially the same direction as the belt pulling direction at the time of a front collision of the vehicle. It is characterized by being extended.

本発明によると、側壁パネルのベルトアンカー設置部の直上近傍に、カーテンシールドエアバッグ装置を取付けるための取付用段部を形成し、この段部の位置と方向をベルト引張方向と略同一方向に合わせるだけで、車両衝突時のベルトアンカーからの引張り荷重に耐えることができるので、車両衝突時のアンカー取付部周辺の変形を抑制することができ、コスト・重量・生産性の面で有効な車両構造を提供することができる。   According to the present invention, a mounting step for mounting the curtain shield airbag device is formed in the side wall panel immediately above the belt anchor mounting section, and the position and direction of this step are substantially the same as the belt pulling direction. Just by matching, it can withstand the tensile load from the belt anchor at the time of vehicle collision, so it is possible to suppress deformation around the anchor attachment part at the time of vehicle collision, and it is an effective vehicle in terms of cost, weight and productivity Structure can be provided.

The coupling member 22 is fitted so as to close the groove 21 from above.

車内側のインナパネル８は、車室３側の凸状に膨出しつつフィックスガラス１２の上縁部よりも上側で車外側にくの字形状に折れ曲がって第１の折曲点２５ａを形成し、その第１の折曲点２５ａの車室３側に凹状のエアバッグ収容空間部２３が形成される。そのバッグ収容空間部２３を形成する第１の折曲点２５ａよりも下方部分は垂直壁２６とされてカーテンシールドエアバッグ装置２８のエアバッグが接し、エアバッグの展開時に垂直壁２６に沿って下方に展開し窓ガラスやフィックスガラス１２とシート座席４との間をシールドするガイド機能を有する。   The inner panel 8 on the inner side of the vehicle bulges in a convex shape on the upper side of the upper portion of the fixed glass 12 toward the outside of the vehicle while bulging into a convex shape on the vehicle cabin 3 side to form a first bending point 25a. A concave airbag accommodating space portion 23 is formed on the vehicle compartment 3 side of the first bending point 25a. A portion below the first bending point 25a forming the bag accommodating space portion 23 is a vertical wall 26, which is in contact with the airbag of the curtain shield airbag device 28, and along the vertical wall 26 when the airbag is deployed. It has a guide function that extends downward and shields between the window glass or fixed glass 12 and the seat 4.

この垂直壁２６の上下方向の長さはエアバッグを収容空間部２３に収容可能な長さであればよい。この垂直壁２６に連続して垂直壁２６の下端部が略直角に車外側に折れ曲がって第２の折曲点２５ｂを形成し、第２の折曲点２５ｂよりも車外側ではほぼ水平な横壁２７を構成している。さらに、横壁２７の車外側の端部が下方に折れ曲がって第３の折曲点２５ｃを形成する。第３の折曲点２５ｃよりも下方近傍にはアンカー取付座面１５が位置している。   The length of the vertical wall 26 in the up-down direction may be a length that can accommodate the airbag in the accommodation space 23. A lower end of the vertical wall 26 is bent outwardly at a substantially right angle to the outside of the vehicle so as to form a second bending point 25b, and the horizontal wall is substantially horizontal on the vehicle outside of the second bending point 25b. 27. Further, the outer end of the lateral wall 27 is bent downward to form a third bending point 25c. The anchor mounting seat surface 15 is located near and below the third bending point 25c.

また、車室３側には、ルーフパネル６からリアピラーインナパネル８にかけて板状の天井部材３０が設置される。この天井部材３０の左右両端部はインナパネル８のエアバッグ収容空間２３の下方に位置する第２の折曲点２５ｂの直下位置まで延設され、横壁２７の車室側端部を覆うように配置される。この天井部材３０の左右両端縁を隠すように横壁２７の下方にはトリム部材３１が配設されている。このトリム部材３１は、フィックスガラス１２を固定するアウタパネル７とインナパネル８の開口１１の端縁部まで覆っている。   A plate-like ceiling member 30 is provided on the vehicle cabin 3 side from the roof panel 6 to the rear pillar inner panel 8. The left and right ends of the ceiling member 30 extend to a position immediately below a second bending point 25b located below the airbag accommodating space 23 of the inner panel 8 so as to cover the end of the side wall 27 on the passenger compartment side. Be placed. A trim member 31 is provided below the horizontal wall 27 so as to hide left and right edges of the ceiling member 30. The trim member 31 covers up to the edge of the opening 11 of the outer panel 7 and the inner panel 8 to which the fix glass 12 is fixed.

エアバッグ収容空間部２３には、カーテンシールドエアバッグ装置２８（以下、略して、「ＣＳＡ装置２８」という場合がある）が収納される。このＣＳＡ装置２８は、左右のエアバッグ２８ａと左右のインフレータ（図示せず）とを含む。左右のエアバッグ２８ａは、車両１の側部の窓（前ドア、後ろドア、フィックスガラス１２）の上縁に沿って折畳状態で配置されると共に、各窓に沿って車室３の前後方向略全体にわたってカーテン状に展開可能となっている。このエアバッグ２８ａは、天井部材３０の端縁部とトリム部材３１の端部の間から車室３側に展開するようになっている。   A curtain shield airbag device 28 (hereinafter, may be abbreviated as “CSA device 28”) is stored in the airbag housing space 23. The CSA device 28 includes left and right airbags 28a and left and right inflators (not shown). The left and right airbags 28a are arranged in a folded state along the upper edges of the windows (front door, rear door, and fixed glass 12) on the side of the vehicle 1, and the front and rear of the passenger compartment 3 along each window. It can be deployed in a curtain shape over almost the entire direction. The airbag 28 a is configured to be deployed toward the vehicle compartment 3 from between the edge of the ceiling member 30 and the end of the trim member 31.

このＣＳＡ装置２８を取付けるために、側壁５のインナパネル８は、第１の折曲点２５ａから垂直壁２６、さらには第２の折曲点２５ｂから横壁２７、さらには第３の折曲点２５ｃに至るまで略直角の段状に形成され、ＣＳＡ装置２８の取付用段部３２を構成している。ＣＳＡ装置２８は、取付段部３２を構成する垂直壁２６に係止フック（図示せず）等を用いてエアバッグ２８ａが取り付けられている。   In order to mount the CSA device 28, the inner panel 8 of the side wall 5 is moved from the first bending point 25a to the vertical wall 26, further from the second bending point 25b to the side wall 27, and further to the third bending point. The CSA device 28 is formed in a substantially right-angled step shape up to 25c. In the CSA device 28, an airbag 28a is attached to the vertical wall 26 forming the attachment step 32 using a locking hook (not shown) or the like.

取付用段部３２は、図１に示すように、前記ベルトアンカー１４の取付座面１５の直上近傍で、車両１の衝突時のベルト引張方向と略同方向に延設されている。また、この横壁側の第２の折曲点２５ｂとバッグ収容空間部２３の第１の折曲点２５ａとはエアバッグ２８ａの収容高さ分だけ離れているが、両折曲点２５ａ、２５ｂが形成する稜線間の距離が近い状態となっている。しかも、第２の折曲点２５ｂは略直角をなすように形成されている。さらに、略直角に折り曲げられた稜線はベルトアンカー１４の取付座面１５を前後方向で跨ぐように前後方向に長く形成されている。   As shown in FIG. 1, the mounting step 32 extends in the same direction as the belt pulling direction at the time of a collision of the vehicle 1 near the mounting seat surface 15 of the belt anchor 14. Further, the second bending point 25b on the side wall side and the first bending point 25a of the bag storage space 23 are separated by the storage height of the airbag 28a, but both bending points 25a, 25b Are in a state where the distance between the ridge lines formed is short. Moreover, the second bending point 25b is formed so as to form a substantially right angle. Further, the ridge line bent at a substantially right angle is formed long in the front-rear direction so as to straddle the mounting seat surface 15 of the belt anchor 14 in the front-rear direction.

上記構成においては、くの字状の第１の折曲点２５ａ、垂直壁２６の下端部の第２の折曲点２５ｂ、さらには横壁２７の第３の折曲点２５ｃで形成されるＣＳＡ取付用の段部３２の断面は、稜線間の距離が近い略直角をなすように形成されており、また、段部３２はベルトアンカー１４の取付座面１５を前後に跨ぐように設定されており、かつ衝突時の引張方向と同じ方向に設定されているので、衝突時にアンカー取付座面１５の周辺部の変形を抑制することができる。この際、ＣＳＡ装置２８は垂直壁２６に沿って下方に展開するため、従来のように、エアバッグを車室側に案内するガイド用ジャンプ台を別途設ける必要がなく、部品点数の軽減が可能となる。   In the above configuration, the CSA formed by the first bent point 25a in the shape of a U-shape, the second bent point 25b at the lower end of the vertical wall 26, and the third bent point 25c of the horizontal wall 27. The cross section of the mounting step portion 32 is formed so as to form a substantially right angle with a short distance between the ridge lines, and the step portion 32 is set so as to straddle the mounting seat surface 15 of the belt anchor 14 back and forth. In addition, since it is set in the same direction as the pulling direction at the time of the collision, the deformation of the peripheral portion of the anchor mounting seat surface 15 at the time of the collision can be suppressed. At this time, since the CSA device 28 is deployed downward along the vertical wall 26, it is not necessary to separately provide a guide jump stand for guiding the airbag to the vehicle compartment side as in the conventional case, and the number of parts can be reduced. Becomes

しかも、アンカー取付座面１５周辺は、ＣＳＡ装置取付用の段部３２を有しているので、アンカー取付部引張荷重対応専用のリンフォースを設ける必要がなく、部品点数及び重量の軽減を図ることができ、生産性を向上させることができる。   Moreover, since the periphery of the anchor mounting seat surface 15 has the step 32 for mounting the CSA device, it is not necessary to provide a dedicated reinforcement for the tensile load of the anchor mounting portion, and the number of parts and weight can be reduced. And productivity can be improved.

なお、本発明は、上記実施形態に限定されるものではなく、本発明の範囲内で多くの修正・変更を加えることができるのは勿論である。例えば、上記実施形態では、リアピラーにおけるベルトアンカーの取付部の補強について説明したが、これに限らず、センターピラーにおけるアンカーの取付部補強構造に本発明を適用してもよいことは勿論である。   It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made within the scope of the present invention. For example, in the above-described embodiment, the reinforcement of the attachment portion of the belt anchor in the rear pillar has been described. However, the present invention is not limited thereto, and the present invention may be applied to a reinforcement structure of the attachment portion of the anchor in the center pillar.
