特開２０１５−９３６０１号公報JP, 2005-93601, A

加飾部品に施される加飾ステッチは、一般的に直線や滑らかな曲線形状とされることが多い。しかしながら、加飾部品が角部を有するものとされ、その角部の外周端部に沿って折れ曲がる加飾ステッチを施したいという要望がある。そのような角部の外周端部に沿って折れ曲がるように加飾ステッチを施す場合、例えば、基材の角部に沿って表皮を貼り付けるために表皮を基材の外側に向かって引っ張ったりすることで、加飾ステッチのズレが生じやすい。また、基材の角部に沿った屈折する加飾ステッチは、そのズレを目視でも認識しやすく、加飾ステッチのズレによる品質の低下が問題となる。   The decorative stitches applied to the decorative component are generally in the form of straight lines or smooth curved lines. However, there is a demand that the decorative component has a corner portion, and that a decorative stitch that is bent along the outer peripheral end portion of the corner portion be provided. When performing a decorative stitch so as to be bent along the outer peripheral edge of such a corner portion, for example, the outer skin may be pulled toward the outside of the base material in order to attach the outer skin along the corner portion of the base material. Therefore, the decorative stitch is likely to be displaced. Further, in the decorative stitch that bends along the corners of the base material, it is easy to visually recognize the deviation, and there is a problem of quality deterioration due to the deviation of the decorative stitch.

本発明は、そのような実情に鑑みてなされたものであり、角部の外周端部に沿って加飾ステッチを施した加飾部品の品質を向上させることを課題とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to improve the quality of a decorative component in which a decorative stitch is applied along the outer peripheral edge of the corner.

上記課題を解決するために本発明の加飾部品は、(a)基材と、(b)前記基材を覆う表皮材と、(c)前記表皮材の表面側に施された加飾ステッチと、(d)前記加飾ステッチに沿って延びる線状をなして前記表皮材の裏面側に前記加飾ステッチによって縫い付けられるとともに、前記基材に対して取り付けられることで前記加飾ステッチの前記基材に対する位置を定めるためのステッチ位置固定部材と、を含んで構成される加飾部品であって、
前記基材は、外周に角部を有する形状とされ、
前記加飾ステッチの一部は、前記角部の外周端部に沿って施されており、
前記ステッチ位置固定部材は、前記角部に沿って折れ曲がる屈折部と、前記屈折部から一端側に延びる第１延在部と、前記屈折部から他端側に延びる第２延在部と、を有する形状とされており、
前記屈折部には、前記第１延在部側から前記第２延在部側に渡って形成されて前記基材に向かって突出する突出部が設けられるとともに、前記基材の前記角部には、前記突出部が嵌まり合う嵌合孔が設けられたことを特徴とする。 In order to solve the above problems, the decorative component of the present invention includes (a) a base material, (b) a skin material covering the base material, and (c) a decorative stitch provided on the surface side of the skin material. And (d) while being sewn to the back surface side of the skin material by the decorative stitch in the form of a line extending along the decorative stitch, and by being attached to the base material, the decorative stitch A decorative part configured to include a stitch position fixing member for determining a position with respect to the base material,
The base material has a shape having a corner on the outer periphery,
Part of the decorative stitch is applied along the outer peripheral edge of the corner,
The stitch position fixing member includes a bending portion that bends along the corner portion, a first extending portion that extends from the bending portion to one end side, and a second extending portion that extends from the bending portion to the other end side. It is supposed to have
The bending portion is provided with a protruding portion that extends from the first extending portion side to the second extending portion side and protrudes toward the base material, and at the corner portion of the base material. Is characterized in that a fitting hole into which the protrusion is fitted is provided.

この構成の加飾部品は、ステッチ位置固定部材の屈折部に設けられた突出部が基材の嵌合孔に嵌まり合うことで、ステッチ位置固定部材は、それの屈折部を基準として、基材に対する位置が定まることになる。つまり、ステッチ位置固定部材の屈折部の基材に対する位置が固定されることで、加飾ステッチの折れ曲がる箇所である屈折点の基材に対する位置が確実に固定される。したがって、この構成の加飾部品は、加飾ステッチの屈折点は基材に対してズレが生じることがないため、当該加飾部品の品質を向上させることができる。   In the decorative component of this configuration, the protrusion provided on the bending portion of the stitch position fixing member fits into the fitting hole of the base material, so that the stitch position fixing member has a base on the basis of the bending portion. The position with respect to the material will be determined. That is, by fixing the position of the bending portion of the stitch position fixing member with respect to the base material, the position of the bending point, which is the bending portion of the decorative stitch, with respect to the base material is reliably fixed. Therefore, in the decorative component having this configuration, the refraction point of the decorative stitch does not deviate from the base material, so that the quality of the decorative component can be improved.

上記構成において、前記第１延在部は、前記第２延在部より長くされており、
前記突出部は、前記第１延在部に沿う部分の寸法が前記第２延在部に沿う部分の寸法より長くされた構成とすることができる。 In the above configuration, the first extending portion is longer than the second extending portion,
The protrusion may be configured such that a dimension of a portion along the first extending portion is longer than a dimension of a portion along the second extending portion.

ステッチ位置固定部材を基材に対して取り付ける際には、第１延在部側はその第１延在部側に引っ張りながら、第２延在部側はその第２延在部側に引っ張りながら、取り付けていくことになる。特に、その延在部の延びる方向が変化しているような形状の場合には、ステッチ位置固定部材の基材への取り付け時に屈折部に作用する力の方向も変化していくことになる。そして、相対的に長くされた第１延在部を取り付ける場合のほうが、第２延在部を取り付ける場合に比較して、屈折部には大きな力が作用する。この構成の加飾部品によれば、突出部は第１延在部に沿う部分の寸法が大きくされていることで、その取付時の力を受けやすくされており、例えば、ステッチ位置固定部材を基材に取付時において、屈折部が基材から外れてしまうような事態を回避することができる。   When attaching the stitch position fixing member to the base material, the first extension portion side is pulled toward the first extension portion side, and the second extension portion side is pulled toward the second extension portion side. , Will be installed. In particular, in the case of a shape in which the extending direction of the extending portion changes, the direction of the force acting on the bending portion also changes when the stitch position fixing member is attached to the base material. When the relatively long first extending portion is attached, a larger force acts on the refracting portion than when the second extending portion is attached. According to the decorative component of this configuration, the protrusion is made larger in the size of the portion extending along the first extending portion, so that it is easier to receive the force at the time of mounting the protrusion. It is possible to avoid a situation in which the refraction portion comes off the base material when it is attached to the base material.

また、上記構成において、前記突出部は、前記屈折部の内周に沿って形成されている構成とすることができる。   Further, in the above structure, the protrusion may be formed along an inner circumference of the refraction part.

この構成の加飾部品は、ステッチ位置固定部材の加飾ステッチが施される部分を基材の外周端に近い位置に配することができる。つまり、この構成の加飾部品は、加飾ステッチの屈折点を、加飾部品の角部における外周端により近づけることができる。   In the decorative component having this configuration, the portion of the stitch position fixing member to which the decorative stitch is applied can be arranged at a position close to the outer peripheral end of the base material. That is, in the decorative component having this configuration, the inflection point of the decorative stitch can be brought closer to the outer peripheral edge of the corner of the decorative component.

また、上記構成において、前記基材は、少なくとも前記角部の外周端部から裏側に向かって立設する立壁部を備え、前記嵌合孔は、前記立壁部の内壁から間隔をおいて形成された構成とすることができる。   Further, in the above structure, the base material includes at least an upright wall portion standing upright from an outer peripheral end of the corner portion toward the back side, and the fitting hole is formed at a distance from an inner wall of the upright wall portion. Can be configured.

例えば、基材の角部に、立壁部から連続して嵌合孔を形成してしまうと、基材自体の剛性が低下してしまうことになるが、この構成の加飾部品によれば、基材の剛性の低下を抑えることができる。なお、この構成の加飾部品は、上述した突出部が屈折部の内周に沿って形成された構成に特に有効である。それらの構成を合わせた加飾部品は、加飾ステッチの屈折点を、加飾部品の角部における外周端に近づけても、基材の剛性の低下を抑えることができるのである。   For example, if a fitting hole is continuously formed in the corner portion of the base material from the standing wall portion, the rigidity of the base material itself will decrease. However, according to the decorative component of this configuration, It is possible to suppress a decrease in the rigidity of the base material. The decorative component having this configuration is particularly effective for a configuration in which the above-mentioned protruding portion is formed along the inner circumference of the bending portion. In the decorative component having those configurations combined, the rigidity of the base material can be prevented from lowering even if the bending point of the decorative stitch is brought close to the outer peripheral edge of the corner of the decorative component.

また、上記構成において、前記第１延在部および前記第２延在部は、延在方向に沿って間隔をおいて配列された複数の被取付部を有し、前記基材は、複数の前記被取付部が取り付けられる複数の取付部を有し、前記被取付部は、前記取付部に対して前記延在方向に隙間を有する状態で取り付けられる構成とすることができる。   Further, in the above-mentioned configuration, the first extending portion and the second extending portion have a plurality of attached portions arranged at intervals along the extending direction, and the base material has a plurality of attached portions. The mounting part may have a plurality of mounting parts to which the mounting part is mounted, and the mounting part may be mounted to the mounting part with a gap in the extending direction.

ステッチ位置固定部材は、成形時に誤差が生じ、被取付部の位置にズレが生じる場合がある。ステッチ位置固定部材を基材に対して取り付ける際に、屈折部を基準として取り付けるが、この構成の加飾部品によれば、そのステッチ位置固定部材の成形時の誤差を、取付部の隙間で吸収することができるため、ステッチ位置固定部材を基材に対して確実に取り付けることができる。   The stitch position fixing member may have an error at the time of molding, and the position of the attached portion may be displaced. When the stitch position fixing member is attached to the base material, it is attached using the refraction portion as a reference. With the decorative component of this configuration, the stitch position fixing member's molding error is absorbed by the gap between the attaching portions. Therefore, the stitch position fixing member can be reliably attached to the base material.

本発明によれば、角部の外周端部に沿って加飾ステッチを施した加飾部品の品質を向上させることができる。   ADVANTAGE OF THE INVENTION According to this invention, the quality of the decorative component which decorated the decorative stitch along the outer peripheral edge part of a corner part can be improved.

そして、上記のアッパボード２０が、本発明の実施例である加飾部品であり、図２から図８をも参照しつつ、以下に詳しく説明することとする。アッパボード２０は、図１および図２に示すように、車両前後方向に延びる長手状で、車両前方側の部分の上下方向の幅が後方側の部分に比較して大きな形状のものとなっている。アッパボード２０は、前方側の幅が大きな部分から後方側の幅の小さい部分にかけて、急激に幅が小さくなるような形状となっており、前方側の幅の広い部分における後端は、ほぼ直角な形状をなしている。   The upper board 20 is a decorative component that is an embodiment of the present invention, and will be described in detail below with reference to FIGS. 2 to 8. As shown in FIGS. 1 and 2, the upper board 20 has a longitudinal shape extending in the vehicle front-rear direction, and has a shape in which the vertical width of the front portion of the vehicle is larger than that of the rear portion. There is. The upper board 20 has a shape in which the width is sharply reduced from a portion having a large width on the front side to a portion having a small width on the rear side, and a rear end of the wide portion on the front side has a substantially right angle. It has a unique shape.

アッパボード２０は、図３に示すように、ポリプロピレン等の合成樹脂材料などによって形成された板状の基材３０と、その基材３０の表面側（車室内側，意匠面側）を覆う表皮材３１と、を主体として構成される。なお、基材３０は、合成材料に限定されず、例えば、木質系材料（ケナフ、ヘンプ、フラックス、サイザルなど）と合成樹脂を混合したものなどを用いてもよい。上述したように、アッパボード２０は、前方側の幅の広い部分における後端がほぼ直角な形状をなしており、基材３０は、それに合わせた形状となっている。具体的には、基材３０は、意匠面を形成する本体部３０ａと、その本体部３０ａの下方側の外周端に沿ってオーナメントボード２２に対して取り付けるための取付片３０ｂとを含んで構成され、その本体部３０ａが、前方側の幅の広い部分における後端に角部３０ｃを有する形状となっている。また、表皮材３１の表面には、図１および図２に示すように、加飾ステッチＳが施されており、表皮材３１が基材３０を覆った状態において、加飾ステッチＳは、基材３０の下端に沿って延びている。つまり、加飾ステッチＳは、基材３０の角部３０ｃに沿ってほぼ直角に折れ曲がる箇所である屈折点ＰＳを有する形状となっている。 As shown in FIG. 3, the upper board 20 includes a plate-shaped base material 30 formed of a synthetic resin material such as polypropylene, and a surface covering the front surface side (vehicle interior side, design surface side) of the base material 30. The material 31 is mainly included. The base material 30 is not limited to a synthetic material, and for example, a material in which a wood-based material (kenaf, hemp, flux, sisal, etc.) and a synthetic resin are mixed may be used. As described above, the rear end of the upper board 20 in the wide portion on the front side has a substantially right angle, and the base material 30 has a shape corresponding thereto. Specifically, the base material 30 includes a main body portion 30a forming a design surface, and a mounting piece 30b for mounting the main body portion 30a to the ornament board 22 along the outer peripheral edge on the lower side of the main body portion 30a. The main body portion 30a has a corner portion 30c at the rear end in the wide portion on the front side. As shown in FIGS. 1 and 2, a decorative stitch S is applied to the surface of the skin material 31, and when the skin material 31 covers the base material 30, the decorative stitch S is It extends along the lower end of the material 30. That is, the decorative stitch S has a shape having the inflection point P S which is a portion that is bent substantially at a right angle along the corner portion 30 c of the base material 30.

また、アッパボード２０は、加飾ステッチＳの基材３０に対する位置を固定するためのステッチ位置固定部材３２（以下、単に「固定部材３２」と呼ぶ場合がある）を備えている。その固定部材３２は、例えば、ポリプロピレン等の合成樹脂材料などによって、加飾ステッチＳに沿って延びる線状の部材とされている。詳しく言えば、図３に示すように、固定部材３２は、基材３０の角部３０ｃに沿って折れ曲がる屈折部３２ａと、その屈折部３２ａから一端側である車両後方側に向かって延びる第１延在部３２ｂと、屈折部３２ａから他端側である車両前方側に向かって延びる第２延在部３２ｃと、を有する形状となっている。なお、第１延在部３２ｂは、屈折部３２ａから、一旦、上方側に延び出して、概して円弧上に湾曲して車両後方側に向かって延びている。   Further, the upper board 20 includes a stitch position fixing member 32 (hereinafter, may be simply referred to as “fixing member 32”) for fixing the position of the decorative stitch S with respect to the base material 30. The fixing member 32 is made of, for example, a synthetic resin material such as polypropylene, and is a linear member extending along the decorative stitch S. More specifically, as shown in FIG. 3, the fixing member 32 includes a bending portion 32a that bends along a corner portion 30c of the base material 30, and a first bending portion 32a that extends from the bending portion 32a toward the vehicle rear side that is one end side. It has a shape including an extending portion 32b and a second extending portion 32c extending from the bending portion 32a toward the vehicle front side which is the other end side. The first extending portion 32b once extends upward from the bending portion 32a, is curved in a generally arcuate shape, and extends toward the vehicle rear side.

また、固定部材３２は、図３に示すように、基材３０の下端側に沿って形成された段差部３０ｄに嵌合可能とされている。そして、固定部材３２が、基材３０の段差部３０ｄに嵌合された状態において、基材３０の表面と固定部材３２の表面とが面一となる（図６〜図８参照）。   Further, as shown in FIG. 3, the fixing member 32 can be fitted into a step portion 30d formed along the lower end side of the base material 30. Then, when the fixing member 32 is fitted in the step portion 30d of the base material 30, the surface of the base material 30 and the surface of the fixing member 32 are flush with each other (see FIGS. 6 to 8).

図３に示すように、基材３０の段差部３０ｄには、平面視で概して長方形状をなす複数の貫通孔４０が形成されている。一方、固定部材３２は、第１延在部３２ｂと第２延在部３２ｃとの各々に、延在方向に沿って間隔をおいて配列された複数の突出部４１を有するものとなっている。固定部材３２の各突出部４１は、基材３０側に向かって突出しており、貫通孔４０に対して表側から取り付けられることで、固定部材３２は、基材３０に対して固定される。   As shown in FIG. 3, a plurality of through holes 40 each having a generally rectangular shape in plan view are formed in the step portion 30d of the base material 30. On the other hand, the fixing member 32 has a plurality of protruding portions 41 arranged at intervals along the extending direction on each of the first extending portion 32b and the second extending portion 32c. . Each protruding portion 41 of the fixing member 32 protrudes toward the base material 30 side, and the fixing member 32 is fixed to the base material 30 by being attached to the through hole 40 from the front side.

第２延在部３２ｃに形成された３つのものおよび第１延在部３２ｂに形成されたもののうち屈折部３２ａに最も近いものの合計４つのものである第１突出部４１ａは、図４、図５および図６に示すように、幅方向に間隔をおいて形成された一対の突起片部４１ａ１，４１ａ２からなり、それら突起片部４１ａ１，４１ａ２が爪を有する形状とされて、複数の貫通孔４０のうちの対応するものである第１貫通孔４０ａの孔縁部に裏側から掛かり止まるようになっている。また、第１延在部３２ｂに形成されたもののうち車両後方側の３つのものである第２突出部４１ｂは、図３に破線で示すように、幅方向における一端側（上方側）からのみ突出して爪を有していない形状のものであり、複数の貫通孔４０のうちの対応するものである第２貫通孔４０ｂに入り込むようになっている。なお、図５に示すように、第１突出部４１ａは、第１貫通孔４０ａに対して、延在方向の寸法が小さくされており、延在方向に隙間を有する状態で掛かり止まっている。第２突出部４１ｂも同様に、第２貫通孔４０ｂに対して、延在方向の寸法が小さくされており、その第２貫通孔４０ｂに入り込んだ状態において、延在方向に隙間を有する状態となっている。つまり、第１突出部４１ａおよび第２突出部４１ｂが、本発明に係る被取付部として機能するとともに、第１貫通孔４０ａおよび第２貫通孔４０ｂが、本発明に係る取付部として機能するものとなっている。   Of the three formed on the second extending portion 32c and the one formed on the first extending portion 32b, which is the closest to the refracting portion 32a, a total of four first protruding portions 41a are shown in FIGS. As shown in FIG. 5 and FIG. 6, it is composed of a pair of protruding piece portions 41a1 and 41a2 formed at intervals in the width direction, and these protruding piece portions 41a1 and 41a2 have a shape having a claw, and a plurality of through holes are formed. The first through hole 40a, which is the corresponding one of the 40, is hooked from the back side to the hole edge portion and stopped. Further, among the three formed on the first extending portion 32b, the two second protruding portions 41b on the vehicle rear side are provided only from one end side (upper side) in the width direction as shown by a broken line in FIG. It has a shape that does not have a claw protruding and is adapted to enter the corresponding second through hole 40b of the plurality of through holes 40. As shown in FIG. 5, the first protruding portion 41a has a smaller dimension in the extending direction than the first through hole 40a, and stops with a gap in the extending direction. Similarly, the second protruding portion 41b has a smaller dimension in the extending direction than the second through hole 40b, and has a gap in the extending direction when the second protruding portion 41b enters the second through hole 40b. Has become. That is, the first protruding portion 41a and the second protruding portion 41b function as the mounted portion according to the present invention, and the first through hole 40a and the second through hole 40b function as the mounting portion according to the present invention. Has become.

屈折部３２ａに形成された第３突出部４１ｃは、図４および図５に示すように、第１延在部３２ｂから第２延在部に渡って形成されるものであり、概してＬ字形状に突出するものとなっている。また、その第３突出部４１ｃは、屈折部３２ａの内周に沿って形成されている。一方、第３突出部４１ｃに対応する第３貫通孔４０ｃは、上方側（車両後方側、第１延在部３２ｂ側）および車両前方側（第２延在部側）の両者に渡って形成された概してＬ字形状のものであり、図５に示すように、第３突出部４１ｃが延在方向にほぼ隙間なく嵌まり合うような大きさに形成されている。つまり、第３突出部４１ｃが、本発明に係る突出部として機能するとともに、第３貫通孔４０ｃが、本発明に係る嵌合孔として機能するものとなっている。   As shown in FIGS. 4 and 5, the third protruding portion 41c formed on the bending portion 32a is formed from the first extending portion 32b to the second extending portion, and is generally L-shaped. It has become a project. The third protruding portion 41c is formed along the inner circumference of the bending portion 32a. On the other hand, the third through hole 40c corresponding to the third protruding portion 41c is formed over both the upper side (vehicle rear side, the first extending portion 32b side) and the vehicle front side (second extending portion side). As shown in FIG. 5, the third protrusion 41c is formed in a size such that the third protrusion 41c is fitted in the extending direction with almost no space therebetween. That is, the third protrusion 41c functions as a protrusion according to the present invention, and the third through hole 40c functions as a fitting hole according to the present invention.

なお、固定部材３２は、第１延在部３２ｂが第２延在部３２ｃより長くされている。そして、第３突出部４１ｃは、図４および図５に示すように、第１延在部３２ｂと第２延在部３２ｃとの各々の長さに合わせて、第１延在部３２ｂに沿った部分４１ｃ１の寸法が第２延在部３２ｃに沿った部分４１ｃ２の寸法より長くされている。   The first extending portion 32b of the fixing member 32 is longer than the second extending portion 32c. Then, as shown in FIGS. 4 and 5, the third projecting portion 41c extends along the first extending portion 32b according to the length of each of the first extending portion 32b and the second extending portion 32c. The dimension of the extended portion 41c1 is longer than the dimension of the portion 41c2 along the second extending portion 32c.

基材３０の本体部３０ａは、図５に示すように、下方側の外周端部に沿って、裏側に向かって立設する立壁部３０ｅを備えている。そして、上記の第３貫通孔４０ｃは、その立壁部３０ｅの内壁から内側に間隔をおいて形成されている。換言すれば、立壁部３０ｅの内壁と、第３貫通孔４０ｃの内壁とが、連続しないように形成されている。立壁部３０ｅの内壁と第３貫通孔４０ｃの内壁とが連続してしまうと、基材３０自体の剛性が低下することになるが、本実施例の加飾部品であるアッパボード２０は、基材３０の剛性の低下が抑えられている。   As shown in FIG. 5, the main body portion 30a of the base material 30 includes a standing wall portion 30e that stands upright toward the back side along the outer peripheral end portion on the lower side. The third through hole 40c is formed at a distance from the inner wall of the standing wall portion 30e toward the inside. In other words, the inner wall of the standing wall portion 30e and the inner wall of the third through hole 40c are formed so as not to be continuous. If the inner wall of the standing wall portion 30e and the inner wall of the third through hole 40c are continuous, the rigidity of the base material 30 itself will decrease, but the upper board 20 which is a decorative component of the present embodiment is The decrease in rigidity of the material 30 is suppressed.

そして、上記のように構成された固定部材３２は、表皮材３１の裏面に加飾ステッチＳに沿って配された状態で、その加飾ステッチＳによって表皮材３１に縫い付けられる。そして、その後、固定部材３２の複数の突出部４１を基材３０の複数の貫通孔４０に嵌め合わせるようにして、固定部材３２が基材３０に取り付けられ、それとともに、表皮材３１が基材３０の表面に貼り付けられているのである。このような構成により、アッパボード２０は、加飾ステッチＳの基材３０に対する位置が固定されたものとなっているのである。   Then, the fixing member 32 configured as described above is sewn to the skin material 31 by the decorative stitch S while being arranged on the back surface of the skin material 31 along the decorative stitch S. Then, after that, the fixing member 32 is attached to the base material 30 by fitting the plurality of protruding portions 41 of the fixing member 32 into the plurality of through holes 40 of the base material 30, and at the same time, the skin material 31 is the base material. It is attached to the surface of 30. With such a configuration, the upper board 20 has a fixed position of the decorative stitch S with respect to the base material 30.

さらに言えば、本実施例のアッパボード２０においては、表皮材３１に縫い付けられた固定部材３２を基材３０に取り付ける際、まず、第３突出部４１ｃを第３貫通孔４０ｃに嵌め入れる。これにより、固定部材３２は、それの屈折部３２ａを基準として、基材３０に対する位置が定まることになる。つまり、屈折部３２ａの基材３０に対する位置が固定されることで、加飾ステッチＳの屈折点ＰＳの基材３０に対する位置が確実に固定される。したがって、本実施例のアッパボード２０においては、加飾ステッチＳの屈折点ＰＳは基材３０に対してズレが生じることがないため、当該アッパボード２０は、高い品質を有するものとなる。 Furthermore, in the upper board 20 of the present embodiment, when the fixing member 32 sewn to the skin material 31 is attached to the base material 30, first, the third protruding portion 41c is fitted into the third through hole 40c. As a result, the position of the fixing member 32 with respect to the base material 30 is determined with reference to the refraction portion 32a. That is, by fixing the position of the bending portion 32a with respect to the base material 30, the position of the bending point P S of the decorative stitch S with respect to the base material 30 is reliably fixed. Thus, the upper board 20 of this embodiment, since no deviation occurs for refraction point P S is the substrate 30 of the decorative stitches S, the upper board 20 comes to have a high quality.

また、第３突出部４１ｃは、屈折部３２ａの内周に沿って形成されているため、固定部材３２の屈折部３２ａを、基材３０の外周端に近い位置に配置することができ、ひいては、加飾ステッチＳの屈折点ＰＳを基材３０の外周端に近い位置に配置することができるのである。なお、前述したように、固定部材３２を外周端に沿って配しているものの、第３突出部４１ｃは内周に沿って形成されているため、基材３０の第３貫通孔４０ｃは立壁部３０ｅの内壁より内側に間隔をおいた位置に配され、基材３０の剛性の低下をも抑える事ができるのである。つまり、上述の、第３貫通孔４０ｃが立壁部３０ｅの内壁から内側に間隔をおいて形成された構成は、第３突出部４１ｃが屈折部３２ａの内周に沿って形成された構成に対して、特に有効である。 Further, since the third projecting portion 41c is formed along the inner circumference of the bending portion 32a, the bending portion 32a of the fixing member 32 can be arranged at a position close to the outer peripheral end of the base material 30, and by extension, , it is possible to arrange the inflection point P S of decorative stitching S at a position near the outer peripheral end of the substrate 30. As described above, although the fixing member 32 is arranged along the outer peripheral edge, the third projecting portion 41c is formed along the inner periphery, so the third through hole 40c of the base material 30 is formed on the standing wall. It is arranged at a position spaced inward from the inner wall of the portion 30e, and it is possible to prevent the rigidity of the base material 30 from decreasing. That is, the above-described configuration in which the third through holes 40c are formed inwardly from the inner wall of the standing wall portion 30e is different from the configuration in which the third protruding portion 41c is formed along the inner circumference of the bending portion 32a. It is especially effective.

本実施例のアッパボード２０は、第３突出部４１ｃを第３貫通孔４０ｃに嵌め入れた後、第１延在部３２ｂおよび第２延在部３２ｃの各々の突出部４１を、屈折部３２ａに近いものから順次取り付けていくことになる。そして、本実施例のアッパボード２０は、第１突出部４１ａが、第１貫通孔４０ａに対して、第２突出部４１ｂが、第２貫通孔４０ｂに対して、延在方向の寸法が小さくされており、延在方向に隙間を有する状態で取り付けられている。そのため、本実施例のアッパボード２０は、固定部材３２に成形誤差（突出部４１の位置ズレ等）が生じていても、その隙間によって、その成形時の誤差を吸収して、第１延在部３２ｂおよび第２延在部３２ｃの突出部４１を貫通孔４０に確実に取り付けることができる。   In the upper board 20 of the present embodiment, after the third protrusion 41c is fitted into the third through hole 40c, the protrusion 41 of each of the first extending portion 32b and the second extending portion 32c is attached to the bending portion 32a. Will be installed in order from the one closest to. In the upper board 20 of this embodiment, the first protrusion 41a has a smaller dimension in the extending direction than the first through hole 40a and the second protrusion 41b has a smaller dimension in the extending direction than the second through hole 40b. And is attached with a gap in the extending direction. Therefore, in the upper board 20 according to the present embodiment, even if the fixing member 32 has a molding error (positional deviation of the projecting portion 41 or the like), the gap allows the error at the time of molding to be absorbed and the first extension. The protrusions 41 of the portion 32b and the second extending portion 32c can be reliably attached to the through hole 40.

さらに、本実施例のアッパボード２０においては、第１延在部３２ｂおよび第２延在部３２ｃの各々の突出部４１を貫通孔４０取り付けて行く際、第１延在部３２ｂおよび第２延在部３２ｃを引っ張りつつ、突出部４１を貫通孔４０取り付けて行くことになる。固定部材３２は、第１延在部３２ｂが第２延在部３２ｃより長くされているため、第１延在部３２ｂの突出部４１を取り付けていく場合には、第２延在部３２ｃの突出部４１を取り付けていく場合に比較して、屈折部３２ａに大きな力が作用すると考えられる。しかしながら、本実施例のアッパボード２０においては、屈折部３２ａに形成された第３突出部４１ｃは第１延在部３２ｂ側の部分４１ｃ１の寸法が第２延在部３２ｃ側の寸法より長くされているため、その第１延在部３２ｂが延在する方向に引っ張られた際に生じる力を受け止めやすくなっている。したがって、本実施例のアッパボード２０によれば、例えば、固定部材３２を基材３０に取り付ける際に、屈折部３２ａが基材３０から外れてしまうような事態を回避することができる。   Furthermore, in the upper board 20 of the present embodiment, when the protrusion 41 of each of the first extending portion 32b and the second extending portion 32c is attached to the through hole 40, the first extending portion 32b and the second extending portion 32c are attached. The protruding portion 41 is attached to the through hole 40 while pulling the existing portion 32c. Since the first extending portion 32b of the fixing member 32 is longer than the second extending portion 32c, when the protruding portion 41 of the first extending portion 32b is attached, the first extending portion 32b of the second extending portion 32c is fixed. It is considered that a large force acts on the bending portion 32a as compared with the case where the protruding portion 41 is attached. However, in the upper board 20 of the present embodiment, in the third projecting portion 41c formed in the bending portion 32a, the dimension of the portion 41c1 on the first extending portion 32b side is made longer than the dimension on the second extending portion 32c side. Therefore, it is easy to receive the force generated when the first extending portion 32b is pulled in the extending direction. Therefore, according to the upper board 20 of the present embodiment, for example, when the fixing member 32 is attached to the base material 30, it is possible to avoid a situation in which the bending portion 32a comes off the base material 30.
