図1には跳ね上げ式車両用シートの外観を示す。図1において、シート本体Sはその車内側の側縁がシートクッションS1下面に設けられた折り畳み式の支持脚Lによって支持されるとともに、車外側の側縁はヒンジ装置Hに支持されている。ヒンジ装置Hは水平な軸体1を備えており、シート本体Sはその前後位置をステー21,22によって上記軸体1に回動可能に結合されている。   FIG. 1 shows the appearance of a flip-up vehicle seat. In FIG. 1, the seat body S is supported by a folding support leg L provided on the lower surface of the seat cushion S <b> 1 at the vehicle inner side edge, and supported by the hinge device H at the vehicle outer side edge. The hinge device H includes a horizontal shaft body 1, and the seat body S is rotatably coupled to the shaft body 1 by stays 21 and 22 at front and rear positions thereof.

軸体1は前後端部がそれぞれ支持ブラケット3A,3Bに架設されており、前後の支持ブラケット3A,3Bは下端が図2、図3に示すように、車両ボデーを構成するホイールハウスインナパネル41に設けた取付ブラケット51,52に固着されている。また、前後の支持ブラケット3A,3Bには、車内方向へ開放する略U字断面(図5参照)に成形され車両前後方向へ水平に延びる連結部材6の両端が固定されて、互いに連結されている。軸体1の周囲には前後位置に一対のコイルバネ7A,7Bが配設され、コイルバネ7A,7Bの各一端71は連結部材6の板面に、他端72は各ステー21,22に固定されて、シート跳ね上げ時の助勢力が各ステー21,22に付与されるようになっている。   The front and rear end portions of the shaft body 1 are installed on the support brackets 3A and 3B, respectively, and the lower end of the front and rear support brackets 3A and 3B has a wheel house inner panel 41 constituting a vehicle body as shown in FIGS. Are fixed to the mounting brackets 51 and 52 provided on the surface. Further, the front and rear support brackets 3A and 3B are connected to each other by fixing both ends of a connecting member 6 formed in a substantially U-shaped cross section (see FIG. 5) that opens in the vehicle interior direction and extending horizontally in the vehicle front-rear direction. Yes. A pair of coil springs 7A and 7B are disposed around the shaft body 1 at the front and rear positions. Each end 71 of the coil springs 7A and 7B is fixed to the plate surface of the connecting member 6, and the other end 72 is fixed to the stays 21 and 22. Thus, the assisting force when the sheet is flipped up is applied to each of the stays 21 and 22.

連結部材6の側面には車両後方寄りの中間位置に取付孔61(図5)が設けてあり、また、当該取付孔61に対応する連結部材6の下面には下方へ向けて位置決めピン62が突設してある。一方、ホイールハウスインナパネル41には、前後の取付ブラケット51,52の間にさらに取付ブラケット8が設けてあり(図4)、これは両側にフランジ部81を有するハット断面に形成されて、これらフランジ部81が、ホイールハウスアウタパネル42(図5)との衝合部に近く剛性の高いホイールハウスインナパネル41の上縁部に接合固定されている。   A mounting hole 61 (FIG. 5) is provided on the side surface of the connecting member 6 at an intermediate position near the rear of the vehicle, and a positioning pin 62 is provided downward on the lower surface of the connecting member 6 corresponding to the mounting hole 61. Projected. On the other hand, the wheel house inner panel 41 is further provided with a mounting bracket 8 between the front and rear mounting brackets 51 and 52 (FIG. 4), which is formed in a hat cross section having flange portions 81 on both sides. The flange portion 81 is joined and fixed to the upper edge portion of the wheel house inner panel 41 having high rigidity close to the abutting portion with the wheel house outer panel 42 (FIG. 5).

取付ブラケット8は垂直断面では図5に示すように縦壁82と横壁83を有する略L字断面になっており、縦壁82には上記連結部材6の取付孔61に対応する位置にウェルドナット84を備えた取付孔821が形成されている。また、横壁83には角型開口831が形成されてここにガイド部材85が嵌着してある。ガイド部材85には中心にガイド孔851が形成されるとともにその上面はガイド孔851に向けて傾斜するガイド面852となっている。   As shown in FIG. 5, the mounting bracket 8 has a substantially L-shaped cross section having a vertical wall 82 and a horizontal wall 83, as shown in FIG. 5, and the vertical nut 82 has a weld nut at a position corresponding to the mounting hole 61 of the connecting member 6. A mounting hole 821 having 84 is formed. Further, a square opening 831 is formed in the horizontal wall 83, and a guide member 85 is fitted therein. A guide hole 851 is formed at the center of the guide member 85, and an upper surface thereof is a guide surface 852 that is inclined toward the guide hole 851.

このような取付構造において、シート本体Sを取り付ける場合には、ヒンジ装置Hを、これを一体に結合したシート本体Sと共に(図4ではシート本体を省略)据付ロボットによって持ち上げ、位置決めピン62をガイド部材85(図5)上へ下降させてガイド孔851内に進入させる。位置決めピン62のガイド孔851内への進入は、ピン先端がガイド面852の傾斜に沿って案内されることによってスムーズになされる。これによってヒンジ装置H(およびシート本体S)の車幅方向での位置決めがなされる。   In such an attachment structure, when the seat body S is attached, the hinge device H is lifted by the installation robot together with the seat body S integrally coupled thereto (the seat body is omitted in FIG. 4), and the positioning pin 62 is guided. The member 85 (FIG. 5) is lowered to enter the guide hole 851. The positioning pin 62 enters the guide hole 851 smoothly by guiding the tip of the pin along the inclination of the guide surface 852. Thus, the hinge device H (and the seat body S) is positioned in the vehicle width direction.

この状態で、前側支持ブラケット3A下端の取付孔を前側取付ブラケット51(図4)上面の取付孔に一致させてこれらにボルト91(図3)を挿入し両者を結合固定する。このようにして、前側支持ブラケット3Aと位置決めピン62によってヒンジ装置Hを二点で位置決めした後、残る後側支持ブラケット3Bをボルト91(図3)で後側取付ブラケット52(図4)に結合固定する。これにより、ヒンジ装置Hの平面視での傾きを最小限に抑えることができる。   In this state, the attachment hole at the lower end of the front support bracket 3A is made to coincide with the attachment hole on the upper surface of the front attachment bracket 51 (FIG. 4), and bolts 91 (FIG. 3) are inserted into these to fix them together. Thus, after positioning the hinge device H at two points by the front support bracket 3A and the positioning pin 62, the remaining rear support bracket 3B is coupled to the rear mounting bracket 52 (FIG. 4) with the bolt 91 (FIG. 3). Fix it. Thereby, the inclination in the planar view of the hinge apparatus H can be suppressed to the minimum.

前後の支持ブラケット3A,3Bを固定すると、連結部材6の取付孔61が取付ブラケット8の取付孔821に一致するから、これらにボルト92(図5)を挿通してウェルドナット84に結合することによって、連結部材6の中間位置が、取付ブラケット8を介してホイールハウスインナパネル41に固定される。   When the front and rear support brackets 3A and 3B are fixed, the mounting hole 61 of the connecting member 6 coincides with the mounting hole 821 of the mounting bracket 8, so that bolts 92 (FIG. 5) are inserted into these and coupled to the weld nut 84. Thus, the intermediate position of the connecting member 6 is fixed to the wheel house inner panel 41 via the mounting bracket 8.

このように連結部材6の中間位置を、剛性の高いホイールハウスインナパネル41上縁部に固定したことにより、コイルバネ7A,7Bの反力が入力してもこれは取付ブラケット8を介して速やかにホイールハウスインナパネル41上縁部に受けられる。したがって、前後の支持ブラケット3A,3Bが変形することはなく、十分な跳ね上げ助勢力を得ることができる。   By fixing the intermediate position of the connecting member 6 to the upper edge of the highly rigid wheel house inner panel 41 in this way, even if the reaction force of the coil springs 7A and 7B is input, this can be quickly done via the mounting bracket 8. The wheel house inner panel 41 is received at the upper edge. Therefore, the front and rear support brackets 3A and 3B are not deformed, and a sufficient raising assist force can be obtained.
