この場合、ベルト引出口５９と上部ベルトガイド３２の横ガイド３６とは、ベルト引出口５９の略上下中間をシートベルト１６が移動するように相対的に構成する。
即ち、ベルト引出口５９から引き出されたシートベルト１６がベルト引出口５９の周縁のカバー部材５５および取付用段部６０に接触しないで移動することを期待し、シートベルト１６の接触抵抗の発生を抑制して操作性を向上させる。
また、シートベルト１６に掛かる荷重は上部ベルトガイド３２が支持し、カバー部材５５にはシートベルト１６の荷重が殆ど掛からず、カバー部材５５が変形・破損するのを防止して、カバー部材５５の変形・破損によるシートベルト１６の伸び発生を防止する。 In this case, the belt outlet 59 and the lateral guide 36 of the upper belt guide 32 are relatively configured so that the seat belt 16 moves substantially in the middle of the belt outlet 59.
That is, it is expected that the seat belt 16 pulled out from the belt pull-out port 59 will move without contacting the cover member 55 and the mounting step 60 on the periphery of the belt pull-out port 59, and the contact resistance of the seat belt 16 is generated. Suppress and improve operability.
Further, the load applied to the seat belt 16 is supported by the upper belt guide 32, the load of the seat belt 16 is hardly applied to the cover member 55, and the cover member 55 is prevented from being deformed / damaged. The seat belt 16 is prevented from being stretched due to deformation or breakage.

カバー部材５５の前側部分には、シートベルト１６の装着用スリット６４を形成する。装着用スリット６４はカバー部材５５の下縁開口部５６からベルト引出口５９に至る間に形成し、装着用スリット６４とベルト引出口５９とは連通させる。シートベルト１６は縦状にして装着用スリット６４から通し、ベルト引出口５９で横向きにしてシートベルト１６にカバー部材５５を通し、このカバー部材５５をステー２５に取付ける。
したがって、カバー部材５５を装着した後、カバー部材５５の取付用段部６０および装着用スリット６４はシートベルト１６の下方に位置して通常は目に触れない。
なお、それ以外のカバー部材５５の外観形状は任意であり、ステー２５および上部ベルトガイド３２の一部ならびにシート側開口部５０を包囲しうる形状であればよい。 A slit 64 for mounting the seat belt 16 is formed in the front portion of the cover member 55. The mounting slit 64 is formed between the lower edge opening 56 of the cover member 55 and the belt outlet 59, and the mounting slit 64 and the belt outlet 59 communicate with each other. The seat belt 16 is formed in a vertical shape and is passed through the mounting slit 64, and the cover member 55 is passed through the seat belt 16 in a lateral direction at the belt outlet 59, and the cover member 55 is attached to the stay 25.
Therefore, after the cover member 55 is mounted, the mounting step 60 and the mounting slit 64 of the cover member 55 are positioned below the seat belt 16 and are not usually visible.
The external shape of the cover member 55 other than that is arbitrary, and may be any shape that can surround a part of the stay 25 and the upper belt guide 32 and the seat side opening 50.

しかして、ステー２５にはカバー支持部材６５を設ける。カバー支持部材６５はカバー部材５５の周縁起立部５７の下縁７０の下方に位置し、カバー部材５５の下縁７０の下方に隙間が発生するのを防止する。
即ち、単にカバー部材５５を背凭シート２のクッション材１０の表皮部材１１上に載せるように取付けると、カバー部材５５の下縁７０の下方のクッション材１０が撓んで、下縁７０の下方に隙間が発生し、外観上の見栄えが悪く、また、この隙間は表皮部材１１の皺発生の原因となることがあるが、カバー支持部材６５はカバー部材５５の下縁７０の下方に隙間が発生するのを防止して、表皮部材１１の外観上の見栄えの低下を防止し、表皮部材１１の皺発生を防止する。 Accordingly, a cover support member 65 is provided on the stay 25. The cover support member 65 is located below the lower edge 70 of the peripheral upright portion 57 of the cover member 55, and prevents a gap from being generated below the lower edge 70 of the cover member 55.
That is, when the cover member 55 is simply mounted so as to be placed on the skin member 11 of the cushion material 10 of the dorsal seat 2, the cushion material 10 below the lower edge 70 of the cover member 55 bends, and below the lower edge 70. A gap is generated and the appearance is not good, and this gap may cause wrinkles of the skin member 11, but the cover support member 65 has a gap below the lower edge 70 of the cover member 55. This prevents the appearance of the skin member 11 from being deteriorated and prevents the skin member 11 from wrinkling.

そのため、実施例では、表皮部材１１が押されて凹む可能性のあるカバー部材５５の下縁７０の全周の下方にカバー支持部材６５の枠体６６の上面を配置しているが、カバー部材５５の一部の周縁起立部５７の下縁７０の下方でもよい。
カバー支持部材６５は枠体６６により形成し、枠体６６にはステー２５および上部ベルトガイド３２の上方から嵌めるための開口部６７を形成する。
カバー支持部材６５の枠体６６は前記カバー部材５５の周縁起立部５７より平面方向に所定幅有して形成し、カバー部材５５の周縁起立部５７の全周の下方位置に位置するように略四角形状により構成し、カバー支持部材６５は、枠体６６の開口部６７をステー２５に上方から嵌合させて、前記背凭フレーム５の上部フレーム２２の上面により載置させて取付ける。 Therefore, in the embodiment, the upper surface of the frame body 66 of the cover support member 65 is disposed below the entire circumference of the lower edge 70 of the cover member 55 that may be depressed when the skin member 11 is pressed. It may be below the lower edge 70 of the peripheral rising portion 57 of a part of 55.
The cover support member 65 is formed by a frame body 66, and the frame body 66 is formed with an opening 67 for fitting from above the stay 25 and the upper belt guide 32.
The frame body 66 of the cover support member 65 is formed to have a predetermined width in the plane direction from the peripheral erected portion 57 of the cover member 55, and is substantially positioned so as to be positioned below the entire circumference of the peripheral erected portion 57 of the cover member 55. The cover support member 65 is mounted in a rectangular shape, with the opening 67 of the frame body 66 fitted into the stay 25 from above and mounted on the upper surface of the upper frame 22 of the dorsal frame 5.

前記開口部６７は、前記枠体６６の略中央に上下に貫通して形成する。開口部６７の内周には少なくとも前記ステー２５の前板２６と左右の側板２７の一部を夫々当接させる。
即ち、開口部６７の内周の左右側にはステー２５の前板２６の左右両側に当接する当接部７５を形成する。
また、カバー支持部材６５にはステー２５の左右の側板２７に設けた係合部７６が係合する係合溝７７を形成する。
したがって、カバー支持部材６５をステー２５に上方から嵌合させると、開口部６７の内周の当接部７５がステー２５の前板２６の左右両側に当接し、カバー支持部材６５の係合溝７５がステー２５の係合部７６に係合する。そのため、当接部７５と係合溝７７によりカバー支持部材６５の前後の位置決めをする。 The opening 67 is formed through substantially vertically at the center of the frame body 66. At least the front plate 26 of the stay 25 and a part of the left and right side plates 27 are brought into contact with the inner periphery of the opening 67.
That is, contact portions 75 that contact the left and right sides of the front plate 26 of the stay 25 are formed on the left and right sides of the inner periphery of the opening 67.
Further, the cover support member 65 is formed with an engagement groove 77 that engages with an engagement portion 76 provided on the left and right side plates 27 of the stay 25.
Therefore, when the cover support member 65 is fitted to the stay 25 from above, the contact portion 75 on the inner periphery of the opening 67 contacts the left and right sides of the front plate 26 of the stay 25, and the engagement groove of the cover support member 65 75 engages with the engaging portion 76 of the stay 25. Therefore, the front and rear positions of the cover support member 65 are determined by the contact portion 75 and the engagement groove 77.

また、開口部６７の左右内縁にステー２５の左右の側板２７が当接するので、カバー支持部材６５の左右の位置決めがされる。
６８は枠体６６の側部に設けた嵌合部であり、背凭フレーム５に設けた補強フレーム６９の上部に嵌合させるものである。
また、カバー支持部材６５の下面側（内面側）には前記背凭フレーム５の上部フレーム２２の上面に係合する円弧面形状に形成した係合面７８を設ける。
係合面７８は、カバー支持部材６５が所定位置に位置するように背凭フレーム５の上部フレーム２２の上面に係合して、嵌合部６８と共に上下方向の位置決め作用を奏する。
また、枠体６６の上面には上方に起立するリブ７１を形成する。リブ７１はカバー部材５５の下縁７０とにより表皮部材１１がカバー部材５５の下方から引き出されるのを防止する作用を期待する。 Further, since the left and right side plates 27 of the stay 25 are in contact with the left and right inner edges of the opening 67, the left and right positions of the cover support member 65 are positioned.
Reference numeral 68 denotes a fitting portion provided on a side portion of the frame body 66, and is fitted to the upper portion of the reinforcing frame 69 provided on the back frame 5.
Further, an engagement surface 78 formed in a circular arc shape that engages with the upper surface of the upper frame 22 of the dorsal frame 5 is provided on the lower surface side (inner surface side) of the cover support member 65.
The engaging surface 78 engages with the upper surface of the upper frame 22 of the dorsal frame 5 so that the cover support member 65 is positioned at a predetermined position, and has a vertical positioning action together with the fitting portion 68.
Further, a rib 71 standing upward is formed on the upper surface of the frame body 66. The rib 71 is expected to prevent the skin member 11 from being pulled out from below the cover member 55 by the lower edge 70 of the cover member 55.

そのため、表皮部材１１がカバー部材５５の下方から引き出されるのは、前記と同様に、表皮部材１１が押されて凹んだ場合が多いので、実施例では、カバー部材５５の前側部分および左右両側部分の内側にリブ７１が位置するように設けているが、カバー部材５５の下縁７０の全周の内側にリブ７１を設けてもよい。 Therefore, the skin member 11 is pulled out from below the cover member 55 in the same way as described above, because the skin member 11 is often depressed by being pushed. Therefore, in the embodiment, the front portion and the left and right side portions of the cover member 55 are used. However, the rib 71 may be provided inside the entire circumference of the lower edge 70 of the cover member 55.

（実施例の作用）
通常、着座者は座席シート３に腰を下ろし、車両用シート１全体をスライドレールにより車体に対して前後させて前後位置調節を行い、背中を背凭シート２に当てがって、リクラインニング装置により背凭シート２の傾斜角度を調節し、シートベルト１６のタングプレート１９をインナーバックル２０に係合させて、シートベルト１６を肩から胸の部分と腰部に装着する。
この場合、タングプレート１９を持ってシートベルト１６をベルトリトラクター１７から引き出すと、シートベルト１６の左右側は傾斜ガイド４０の左右の側板４２から上部ベルトガイド３２のガイド部３３の側部ガイド３７により連続して規制されて左右方向に振れずに引き出される。 (Operation of Example)
Normally, the seated person sits down on the seat seat 3, adjusts the front / rear position by moving the entire vehicle seat 1 back and forth with respect to the vehicle body by the slide rail, and puts the back on the dorsal seat 2, so that the reclining device By adjusting the inclination angle of the dorsal seat 2, the tongue plate 19 of the seat belt 16 is engaged with the inner buckle 20, and the seat belt 16 is mounted from the shoulder to the chest and the waist.
In this case, when the seat belt 16 is pulled out from the belt retractor 17 with the tongue plate 19, the left and right sides of the seat belt 16 are moved from the left and right side plates 42 of the inclined guide 40 to the side guide 37 of the guide portion 33 of the upper belt guide 32. Is pulled out without swinging in the left-right direction.

また、ベルトリトラクター１７から略上方に移動するシートベルト１６は傾斜ガイド４０の傾斜部４１により斜め上方に案内され、上部ベルトガイド３２のガイド部３３の横ガイド３６により前方に向けて方向変換されて引き出される。
しかして、上部ベルトガイド３２の一部はシートベルト１６を背凭シート２の上部に接触させないようにするために、背凭シート２の上部より所定高さ上方に突出しており、また、背凭シート２の上部のクッション材１０および表皮部材１１には上部ベルトガイド３２の一部を上方に突出させるためのシート側開口部５０を形成し、この上部ベルトガイド３２の一部およびシート側開口部５０を包囲するカバー部材５５を背凭シート２の上部に設けているから、上部ベルトガイド３２の一部およびシート側開口部５０はカバー部材５５により包囲される。 Further, the seat belt 16 that moves substantially upward from the belt retractor 17 is guided obliquely upward by the inclined portion 41 of the inclined guide 40, and the direction is changed forward by the lateral guide 36 of the guide portion 33 of the upper belt guide 32. Pulled out.
Thus, a part of the upper belt guide 32 protrudes above the upper portion of the dorsal seat 2 by a predetermined height so that the seat belt 16 does not come into contact with the upper portion of the dorsal seat 2. The cushion material 10 and the skin member 11 at the upper part of the seat 2 are formed with a seat side opening 50 for projecting a part of the upper belt guide 32 upward, and the part of the upper belt guide 32 and the seat side opening are formed. Since the cover member 55 that surrounds 50 is provided in the upper part of the back sheet 2, a part of the upper belt guide 32 and the seat side opening 50 are surrounded by the cover member 55.

カバー部材５５は、下部の開口部５６の周囲に周縁起立部５７をカップ形状に形成し、カバー部材５５には前後方向に開口するベルト引出口５９を形成しているから、カバー部材５５のベルト引出口５９からシートベルト１６は引き出される。
この場合、カバー部材５５のベルト引出口５９は前後方向に貫通させて開口させているので、ベルト引出口５９から塵埃等の異物がカバー部材５５内に進入するのを防止し、シートベルト１６の作動を確実にする。 Since the cover member 55 has a peripheral edge rising portion 57 formed in a cup shape around the lower opening 56 and the cover member 55 has a belt outlet 59 that opens in the front-rear direction. The seat belt 16 is pulled out from the pull-out port 59.
In this case, since the belt pull-out port 59 of the cover member 55 is opened so as to penetrate in the front-rear direction, foreign matter such as dust is prevented from entering the cover member 55 from the belt pull-out port 59, and the seat belt 16 Ensure operation.

しかして、カバー部材５５の一部または全部の下縁７０の下方にはカバー支持部材６５を設けているから、カバー部材５５周辺の表皮部材１１およびクッション材１０が押されても、カバー支持部材６５の高さ位置は変化せず、そのため、カバー部材５５の下縁７０の下方に隙間が発生するのを防止し、この隙間による外観上見栄えが悪くなるのを防止する。
即ち、単にカバー部材５５を背凭シート２のクッション材１０の表皮部材１１上に載せるように取付けると、カバー部材５５の下縁７０の下方のクッション材１０が撓んだときに、下縁７０の下方に隙間が発生し、この隙間自体が外観上見栄えが悪くなる原因となるが、本願ではカバー支持部材６５がカバー部材５５を支持して、下縁７０の下方に隙間が発生するのを防止するので、外観上見栄えを向上させる。 Since the cover support member 65 is provided below a part or all of the lower edge 70 of the cover member 55, the cover support member even if the skin member 11 and the cushion material 10 around the cover member 55 are pressed. The height position of 65 does not change. Therefore, it is possible to prevent a gap from being generated below the lower edge 70 of the cover member 55, and to prevent the appearance from being deteriorated by the gap.
That is, when the cover member 55 is simply mounted so as to be placed on the skin member 11 of the cushion material 10 of the dorsal seat 2, when the cushion material 10 below the lower edge 70 of the cover member 55 is bent, the lower edge 70. However, in the present application, the cover support member 65 supports the cover member 55, and the gap is generated below the lower edge 70. Since it prevents, it improves the appearance.

また、カバー支持部材６５はカバー部材５５を支持しているので、カバー部材５５周辺のクッション材１０が押されて凹んでもカバー部材５５の下縁７０の下方に隙間が発生するのを防止する。
したがって、カバー支持部材６５がカバー部材５５の下縁７０の下方に隙間が発生するのを防止しているから、皺発生の原因となるカバー部材５５下方の表皮部材１１（クッション材１０）が凹むことをカバー支持部材６５により未然に防止するので、カバー部材５５の下縁７０の下方に隙間が発生すること自体を抑制し、表皮部材１１の皺発生を抑制(防止）する。 Further, since the cover support member 65 supports the cover member 55, a gap is prevented from being generated below the lower edge 70 of the cover member 55 even when the cushion material 10 around the cover member 55 is pushed and recessed.
Therefore, since the cover support member 65 prevents a gap from being generated below the lower edge 70 of the cover member 55, the skin member 11 (cushion material 10) below the cover member 55 that causes wrinkles is recessed. This is prevented in advance by the cover support member 65, so that the occurrence of a gap itself below the lower edge 70 of the cover member 55 is suppressed, and the generation of wrinkles on the skin member 11 is suppressed (prevented).

しかして、カバー支持部材６５の枠体６６は、表皮部材１１（クッション材１０）が押されて凹む可能性のあるカバー部材５５の下縁７０の全周の下方に配置しているので、カバー部材５５の下縁７０の全周に隙間が発生するの防止する。
カバー支持部材６５は枠体６６により形成し、枠体６６にはステー２５（上部ベルトガイド３２を含む）の上方から嵌めるための開口部６７を形成しているので、カバー支持部材６５は枠体６６の開口部６７をステー２５（上部ベルトガイド３２）に上方から嵌合させれば、取り付けられる。
また、開口部６７の内周には少なくとも前記ステー２５の前板２６と左右の側板２７の一部を夫々当接させているので、カバー支持部材６５は前後左右に位置ずれせず、カバー部材５５を確実に支持する。 Therefore, the frame body 66 of the cover support member 65 is disposed below the entire circumference of the lower edge 70 of the cover member 55 that may be depressed by pressing the skin member 11 (cushion material 10). A gap is prevented from occurring around the entire periphery of the lower edge 70 of the member 55.
The cover support member 65 is formed by a frame body 66, and an opening 67 for fitting from above the stay 25 (including the upper belt guide 32) is formed in the frame body 66. If the opening 67 of 66 is fitted to the stay 25 (upper belt guide 32) from above, it is attached.
In addition, since at least the front plate 26 of the stay 25 and a part of the left and right side plates 27 are in contact with the inner periphery of the opening 67, the cover support member 65 is not displaced from front to back and left and right. 55 is securely supported.

即ち、開口部６７の内周の左右側にはステー２５の前板２６の左右両側に当接する当接部７５を形成し、カバー支持部材６５にはステー２５の左右の側板２７に設けた係合部７６が係合する係合溝７７を形成しているので、カバー支持部材６５をステー２５に上方から嵌合させると、開口部６７の内周の当接部７５がステー２５の前板２６の左右両側に当接し、カバー支持部材６５の係合溝７５がステー２５の係合部７６に係合する。そのため、当接部７５と係合溝７７によりカバー支持部材６５の前後の位置決めが保持される。
また、開口部６７の左右内縁にステー２５の左右の側板２７が当接するので、カバー支持部材６５の左右の位置決めがされる。 That is, contact portions 75 that contact the left and right sides of the front plate 26 of the stay 25 are formed on the left and right sides of the inner periphery of the opening 67, and the cover support member 65 is provided on the left and right side plates 27 of the stay 25. Since the engagement groove 77 that engages with the mating portion 76 is formed, when the cover support member 65 is fitted to the stay 25 from above, the contact portion 75 on the inner periphery of the opening 67 becomes the front plate of the stay 25. 26, the engagement groove 75 of the cover support member 65 is engaged with the engagement portion 76 of the stay 25. Therefore, the front / rear positioning of the cover support member 65 is maintained by the contact portion 75 and the engagement groove 77.
Further, since the left and right side plates 27 of the stay 25 are in contact with the left and right inner edges of the opening 67, the left and right positions of the cover support member 65 are positioned.

また、カバー支持部材６５の下面側（内面側）には前記背凭フレーム５の上部フレーム２２の上面に係合する円弧面形状に形成した係合面７８を設けているので、係合面７８は、カバー支持部材６５が所定位置に位置するように背凭フレーム５の上部フレーム２２の上面に係合して、嵌合部６８と共に上下方向の位置決め作用を奏する。
しかして、カバー部材５５は、ステー２５の突出片２８の上面に取付螺子２９により固定状態に取付けているから、カバー部材５５およびカバー支持部材６５の双方がステー２５により位置決めされ、上部ベルトガイド３２の一部およびシート側開口部５０を包囲すると共に、位置ずれによる皺発生も防止して、合理的な構成となる。 Further, since an engagement surface 78 formed in an arc surface shape that engages with the upper surface of the upper frame 22 of the dorsal frame 5 is provided on the lower surface side (inner surface side) of the cover support member 65, the engagement surface 78 is provided. Engages with the upper surface of the upper frame 22 of the dorsal frame 5 so that the cover support member 65 is positioned at a predetermined position, and performs a vertical positioning action together with the fitting portion 68.
Since the cover member 55 is fixedly attached to the upper surface of the protruding piece 28 of the stay 25 by the attachment screw 29, both the cover member 55 and the cover support member 65 are positioned by the stay 25, and the upper belt guide 32 is positioned. And a sheet side opening 50 are surrounded, and wrinkles due to misalignment are also prevented, resulting in a rational configuration.

また、カバー部材５５はカバー支持部材６５により支持され、カバー支持部材６５は背凭フレーム５の上部フレーム２２に支持されているから、カバー支持部材６５とカバー部材５５の下縁７０との高さ位置の寸法精度を向上させ、この点でも、表皮部材１１に皺が発生するのを防止する。
即ち、単にカバー部材５５を背凭シート２のクッション材１０の表皮部材１１上に載せて取付けると、クッション材１０の厚さやカバー部材５５の下縁７０の高さ等の製造精度や組立精度により、カバー部材５５の下縁７０が表皮部材１１およびクッション材１０を下方に押し付けることがあり、表皮部材１１の皺発生の原因となったり、あるいは、カバー部材５５周辺の表皮部材１１の沈み量が一定とならず、外観の見栄えがよくないことがあるが、本願ではカバー支持部材６５がカバー部材５５の下縁７０を支持し、表皮部材１１およびクッション材１０を下方に押し付けないので、カバー部材５５が表皮部材１１およびクッション材１０に対する押し付けや弛みの反復によって生じる皺発生を防止し、カバー部材５５周辺の表皮部材１１（クッション材１０）の沈み量を一定にして外観の見栄えを良好にする。 Further, since the cover member 55 is supported by the cover support member 65, and the cover support member 65 is supported by the upper frame 22 of the dorsal frame 5, the height between the cover support member 65 and the lower edge 70 of the cover member 55. The dimensional accuracy of the position is improved, and also in this respect, the occurrence of wrinkles on the skin member 11 is prevented.
That is, if the cover member 55 is simply mounted on the skin member 11 of the cushion material 10 of the dorsal seat 2, it depends on the manufacturing accuracy and assembly accuracy such as the thickness of the cushion material 10 and the height of the lower edge 70 of the cover member 55. The lower edge 70 of the cover member 55 may press the skin member 11 and the cushion material 10 downward, which may cause wrinkling of the skin member 11 or the sinking amount of the skin member 11 around the cover member 55 may be reduced. In this application, the cover support member 65 supports the lower edge 70 of the cover member 55 and does not press the skin member 11 and the cushion material 10 downward. 55 prevents the generation of wrinkles caused by repeated pressing and loosening on the skin member 11 and the cushion material 10, and the skin member 1 around the cover member 55. To improve the appearance of appearance in the constant sinking amount (the cushion material 10).

しかして、カバー支持部材６５は、四角形状の枠体６６の上面に上方に起立するリブ７１を形成しているから、リブ７１はカバー部材５５の下縁７０とにより表皮部材１１を挟持して、カバー部材５５の下方からの表皮部材１１の引き出しを一層確実に防止でき、好適である。
しかして、カバー部材５５は、その下部を開放して開口部５６を形成し、開口部５６の周囲に周縁起立部５７を設けてカップ形状に形成し、周縁起立部５７の左右両側および後部には頂部５８を続いて形成し、頂部５８の前側にはベルト引出口５９を形成し、ベルト引出口５９は略前後方向に開口させ、ベルト引出口５９の内側に上部ベルトガイド３２のガイド部３３の横ガイド３６を臨ませているから、シートベルト１６は上部ベルトガイド３２の横ガイド３６によりベルト引出口５９の下縁に摺接せずに移動する。 Since the cover support member 65 is formed with a rib 71 standing upward on the upper surface of the rectangular frame 66, the rib 71 sandwiches the skin member 11 with the lower edge 70 of the cover member 55. The pulling out of the skin member 11 from below the cover member 55 can be more reliably prevented, which is preferable.
Thus, the cover member 55 is opened at its lower portion to form an opening 56, and a peripheral edge rising portion 57 is provided around the opening 56 to form a cup shape. The belt 58 is formed in the front side of the top 58, the belt outlet 59 is opened in the front-rear direction, and the guide portion 33 of the upper belt guide 32 is formed inside the belt outlet 59. Therefore, the seat belt 16 moves without being in sliding contact with the lower edge of the belt outlet 59 by the lateral guide 36 of the upper belt guide 32.

したがって、上部ベルトガイド３２のガイド部３３の横ガイド３６は、シートベルト１６とカバー部材５５との接触抵抗の発生を抑制できて、軽くシートベルト１６を引き出せて操作性を向上させる。
また、ベルト引出口５９の内側に上部ベルトガイド３２のガイド部３３の横ガイド３６を臨ませているから、シートベルト１６に掛かる荷重は上部ベルトガイド３２が支持し、カバー部材５５にはシートベルト１６の荷重が殆ど掛からない。
したがって、カバー部材５５がシートベルト１６に掛かる荷重により変形・破損するのを防止して、カバー部材５５の変形・破損によるシートベルト１６の伸び発生を防止でき、シートベルト１６による着座者の拘束状態を良好に保持する。
また、カバー部材５５のベルト引出口５９はシートベルト１６に対して上下に隙間を有するように開口しているので、ベルト引出口５９から引き出されときのシートベルト１６の接触抵抗の発生はなく、操作性を向上させる。 Accordingly, the lateral guide 36 of the guide portion 33 of the upper belt guide 32 can suppress the occurrence of contact resistance between the seat belt 16 and the cover member 55, and the seat belt 16 can be pulled out lightly to improve operability.
Further, since the lateral guide 36 of the guide portion 33 of the upper belt guide 32 faces the inner side of the belt outlet 59, the load applied to the seat belt 16 is supported by the upper belt guide 32, and the seat belt is supported by the cover member 55. The load of 16 is hardly applied.
Therefore, the cover member 55 can be prevented from being deformed / damaged by a load applied to the seat belt 16, and the seat belt 16 can be prevented from being stretched due to the deformation / damage of the cover member 55. Keep good.
Further, since the belt outlet 59 of the cover member 55 is opened so as to have a vertical gap with respect to the seat belt 16, there is no occurrence of contact resistance of the seat belt 16 when being pulled out from the belt outlet 59, Improve operability.

しかして、ベルトリトラクター１７から上方に移動したシートベルト１６を、カバー部材５５のベルト引出口５９から前方に向けて略直角方向に方向変換させる上部ベルトガイド３２は、丸棒部材により形成しているので、製造が容易であり、生産コストを低くする。
また、上部ベルトガイド３２は上部フレーム２２に固定のステー２５に固定され、ステー２５は前板２６と側板２７により平面視「コ」の字形状に形成しており、上部ベルトガイド３２は横ガイド３６と側部ガイド３７とにより平面視「コ」の字形状に形成しているので、ステー２５と上部ベルトガイド３２はボックス状に上部フレーム２２に固定される。
したがって、上部ベルトガイド３２はシートベルト１６の荷重を強固に支持する。 Thus, the upper belt guide 32 that changes the direction of the seat belt 16 that has moved upward from the belt retractor 17 in a substantially perpendicular direction from the belt outlet 59 of the cover member 55 to the front is formed by a round bar member. Therefore, it is easy to manufacture and lowers the production cost.
The upper belt guide 32 is fixed to a stay 25 fixed to the upper frame 22, and the stay 25 is formed in a U shape by a front plate 26 and a side plate 27, and the upper belt guide 32 is a lateral guide. The stay 25 and the upper belt guide 32 are fixed to the upper frame 22 in a box shape because the 36 and the side guides 37 form a “U” shape in plan view.
Therefore, the upper belt guide 32 firmly supports the load of the seat belt 16.

しかして、ステー２５の前板２６の下部は上部フレーム２２より下方に位置させ、上部フレーム２２の下面に上部ベルトガイド３２の円弧部３４を固定しているので、ステー２５の側板２７の下部と上部ベルトガイド３２の円弧部３４により上部フレーム２２を上下に挟持する。
また、ステー２５の前板２６の下方部分と上部ベルトガイド３２の縦軸部３５により上部フレーム２２を前後に挟持して固定しているから、一層、ステー２５と上部ベルトガイド３２は上部フレーム２２に強固に固定され、前後左右方向のみならず上部フレーム２２の円周方向にステー２５が回転するように作用する荷重に対しても強固に支持される。 Thus, the lower portion of the front plate 26 of the stay 25 is positioned below the upper frame 22, and the arc portion 34 of the upper belt guide 32 is fixed to the lower surface of the upper frame 22. The upper frame 22 is vertically clamped by the arc 34 of the upper belt guide 32.
Further, since the upper frame 22 is sandwiched and fixed by the lower portion of the front plate 26 of the stay 25 and the longitudinal portion 35 of the upper belt guide 32, the stay 25 and the upper belt guide 32 are further separated from each other by the upper frame 22. And is firmly supported against a load acting so that the stay 25 rotates in the circumferential direction of the upper frame 22 as well as in the front-rear and left-right directions.

上部ベルトガイド３２は丸棒部材により形成し、上部ベルトガイド３２の上部は左右方向の横ガイド横ガイド３６の左右両側に側部ガイド側部ガイド３７を設けて平面視「コ」の字形状に形成したガイド部ガイド部３３に形成しているので、横ガイド３６と側部ガイド３７は繋がっており、横ガイド３６から横にシートベルト１６が滑っても側部ガイド３７によりガイド部３３から外れることなく、シートベルト１６の案内を確実にする。
しかして、ステー２５の前板２６と左右の側板２７により包囲された空間内には、上部ベルトガイド３２の横ガイド３６に向けてシートベルト１６を斜めに案内する傾斜ガイド４０を設けているので、ベルトリトラクター１７から引き出されるシートベルト１６の裏面は傾斜ガイド４０の傾斜部４１により上部ベルトガイド３２に向けて案内され、シートベルト１６の左右測縁は傾斜ガイド４０の左右の側板４２により案内される。 The upper belt guide 32 is formed of a round bar member, and the upper portion of the upper belt guide 32 is provided with side guide side guides 37 on both the left and right sides of the lateral guide lateral guide 36 in the left-right direction so as to have a “U” shape in plan view. Since it is formed in the formed guide part guide part 33, the lateral guide 36 and the side part guide 37 are connected, and even if the seat belt 16 slides sideways from the lateral guide 36, the side part guide 37 disengages from the guide part 33. Without any problem, the seat belt 16 is reliably guided.
Accordingly, in the space surrounded by the front plate 26 and the left and right side plates 27 of the stay 25, an inclined guide 40 for guiding the seat belt 16 obliquely toward the lateral guide 36 of the upper belt guide 32 is provided. The back surface of the seat belt 16 pulled out from the belt retractor 17 is guided toward the upper belt guide 32 by the inclined portion 41 of the inclined guide 40, and the lateral measurement of the seat belt 16 is guided by the left and right side plates 42 of the inclined guide 40. Is done.

この場合、傾斜ガイド４０は合成樹脂により形成しているので、シートベルト１６の案内機構を軽量化する。
また、傾斜ガイド４０の傾斜部４１の前面には、ステー２５の係合孔４３に係合する係合部４４を形成しているから、傾斜ガイド４０はステー２５の側板２７間に傾斜部４１および側板４２を嵌め込んで、係合部４４を係合孔４３に係合させて取付けるので、特別な工具は不要で、組立を容易にする。 In this case, since the inclined guide 40 is made of synthetic resin, the weight of the seat belt 16 guide mechanism is reduced.
Further, since the engaging portion 44 that engages with the engaging hole 43 of the stay 25 is formed on the front surface of the inclined portion 41 of the inclined guide 40, the inclined guide 40 is interposed between the side plates 27 of the stay 25. Since the side plate 42 is fitted and the engaging portion 44 is engaged with the engaging hole 43 and attached, a special tool is not required and assembly is facilitated.
