以下、本発明の一実施形態を図１〜図６に基づいて説明する。図１に示すように、本実施形態に係る表皮材１０は、基材５１の表側面５１Ｍを被覆して、本発明に係る「乗物用内装部品」としてのアームレスト５０を構成する。   Hereinafter, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the skin material 10 according to the present embodiment covers the front side surface 51 </ b> M of the base material 51 to constitute the armrest 50 as the “vehicle interior part” according to the present invention.

基材５１は、下端が開口した箱状をなし、天井壁５１Ａと前面壁５１Ｂと側壁５１Ｃ，５１Ｃとを備えている。そして、天井壁５１Ａと前面壁５１Ｂとによって、本発明に係るＬ型壁部５２が形成されている。なお、前面壁５１Ｂの上下方向の長さは、天井壁５１Ａの前後方向の長さよりも短くなっていて、前面壁５１ＢがＬ型壁部５２におけるＬ字の短辺部を構成し、天井壁５１ＡがＬ型壁部５２におけるＬ字の長辺部を構成している。   The base material 51 has a box shape with an open lower end, and includes a ceiling wall 51A, a front wall 51B, and side walls 51C and 51C. An L-shaped wall portion 52 according to the present invention is formed by the ceiling wall 51A and the front wall 51B. Note that the length of the front wall 51B in the vertical direction is shorter than the length of the ceiling wall 51A in the front-rear direction, and the front wall 51B constitutes an L-shaped short side portion of the L-shaped wall portion 52. 51A constitutes an L-shaped long side portion of the L-shaped wall portion 52.

表皮材１０は、例えば、本革製の表皮片１１を複数縫い合わせてなり、基材５１の外形とほぼ同じ形状に縫製されている。具体的には、複数の表皮片１１には、基材５１の天井壁５１Ａと前面壁５１Ｂとを表側から覆う第１表皮片１１Ａと、基材５１の側壁５１Ｃ，５１Ｃを表側から覆う第２表皮片１１Ｂ，１１Ｂとが備えられている。   The skin material 10 is formed by stitching a plurality of skin pieces 11 made of genuine leather, for example, and is sewed into a shape substantially the same as the outer shape of the base material 51. Specifically, the plurality of skin pieces 11 include a first skin piece 11A that covers the ceiling wall 51A and the front wall 51B of the base material 51 from the front side, and a second skin that covers the side walls 51C and 51C of the base material 51 from the front side. Skin pieces 11B and 11B are provided.

図２に示すように、第１表皮片１１Ａと第２表皮片１１Ｂとは、縫合糸１３によって縫い合わされている。第１表皮片１１Ａと第２表皮片１１Ｂの縫い代１２，１２は、表皮材１０の裏側へ入り込むように折り返されている。そして、表皮材１０を表側から見たときに、第１表皮片１１Ａと第２表皮片１１Ｂの間に境界線１１Ｌが形成されている。   As shown in FIG. 2, the first skin piece 11 </ b> A and the second skin piece 11 </ b> B are stitched together by the suture thread 13. The seam allowances 12, 12 of the first skin piece 11A and the second skin piece 11B are folded back so as to enter the back side of the skin material 10. When the skin material 10 is viewed from the front side, a boundary line 11L is formed between the first skin piece 11A and the second skin piece 11B.

縫い代１２，１２は、第１表皮片１１Ａ側に倒され、縫い付け糸１７によって第１表皮片１１Ａに縫い付けられている。縫い付け糸１７は、縫合糸１３により形成される縫い目１３Ｌに沿って延びて装飾ステッチ１４を形成する。そして、縫い代１２，１２と、第１表皮片１１Ａのうち縫い代１２，１２が重ね合わされた部分とによって、本発明の縫合部１５が形成されている。このように、本実施形態では、縫合部１５の厚さが、表皮片１１を３枚重ねた厚さとほぼ同じになっている。   The seam allowances 12 and 12 are tilted to the first skin piece 11 </ b> A side, and are sewn to the first skin piece 11 </ b> A by the sewing thread 17. The sewing thread 17 extends along the seam 13 </ b> L formed by the suture 13 to form a decorative stitch 14. And the stitching | suture part 15 of this invention is formed by the seam allowances 12 and 12 and the part by which the seam allowances 12 and 12 were piled up among 11 A of 1st skin pieces. Thus, in the present embodiment, the thickness of the stitched portion 15 is substantially the same as the thickness of the three skin pieces 11 stacked.

図１に示すように、表皮材１０の下端部からは、帯状のストラップ２０が下方に延びている。具体的には、ストラップ２０は、表皮材１０のうち基材５１の前面壁５１Ｂを覆う部分から装飾ステッチ１４に沿って下方へ延びている。ここで、装飾ステッチ１４は縫い目１３Ｌ（図２参照）に沿って延びているので、ストラップ２０は、縫い目１３Ｌに沿って延びることになる。なお、図１の例では、ストラップ２０が表皮材１０の両側部に１つずつ配置されているが、一方の側部にのみ配置されてもよい。   As shown in FIG. 1, a belt-like strap 20 extends downward from the lower end portion of the skin material 10. Specifically, the strap 20 extends downward along the decorative stitch 14 from a portion of the skin material 10 that covers the front wall 51 </ b> B of the base material 51. Here, since the decorative stitch 14 extends along the seam 13L (see FIG. 2), the strap 20 extends along the seam 13L. In addition, in the example of FIG. 1, the strap 20 is arrange | positioned 1 each in the both sides of the skin material 10, However, You may arrange | position only in one side part.

図３及び図４に示すように、ストラップ２０は、例えば、不織布又は布地によって構成され、装飾ステッチ１４によって縫合部１５に共縫いされている。即ち、装飾ステッチ１４を形成する縫い付け糸１７が、本発明の「縫合部にストラップを共縫いする糸」に相当する。   As shown in FIGS. 3 and 4, the strap 20 is made of, for example, a non-woven fabric or a fabric, and is stitched together with the stitching portion 15 by a decorative stitch 14. That is, the sewing thread 17 forming the decorative stitch 14 corresponds to “a thread for sewing the strap together with the stitching portion” of the present invention.

図３に示すように、縫い付け糸１７は、ストラップ２０のうち表皮片１１より外側に延出した延出部２０Ａにも縫い付けられている。別の言い方をすれば、装飾ステッチ１４は、延出部２０Ａまで延長されている。なお、装飾ステッチ１４は、ストラップ２０の幅方向の中央部に配置されている。   As shown in FIG. 3, the sewing thread 17 is also sewn to an extended portion 20 </ b> A that extends outward from the skin piece 11 in the strap 20. In other words, the decorative stitch 14 is extended to the extending portion 20A. The decorative stitch 14 is disposed at the center of the strap 20 in the width direction.

表皮材１０の構造に関する説明は以上である。次に、表皮材１０を用いたアームレスト５０の製造方法について説明する。   This completes the description of the structure of the skin material 10. Next, a method for manufacturing the armrest 50 using the skin material 10 will be described.

アームレスト５０を製造するには、まず、基材５１の表側面５１Ｍに表皮材１０が宛がわれる。このとき、表皮材１０は、基材５１のＬ型壁部５２（天井壁５１Ａ及び前面壁５１Ｂ）を表側から覆い、表皮材１０の縫合部１５が、Ｌ型壁部５２の折れ目、即ち、天井壁５１Ａと前面壁５１Ｂとの間の境界部分を横切るように配置される（図１参照）。また、前面壁５１Ｂの表側には、図１及び図５に示すように、上下方向に延びた受容溝５３（本発明の「受容凹部」に相当する。）が形成されていて、この受容溝５３に表皮材１０の縫合部１５が受容される。これにより、表皮材１０の縫合部１５が前側に膨出することが抑えられている。   In order to manufacture the armrest 50, first, the skin material 10 is applied to the front side surface 51 </ b> M of the base material 51. At this time, the skin material 10 covers the L-shaped wall portion 52 (ceiling wall 51A and front wall 51B) of the base material 51 from the front side, and the stitching portion 15 of the skin material 10 is a fold of the L-shaped wall portion 52, that is, These are arranged so as to cross the boundary portion between the ceiling wall 51A and the front wall 51B (see FIG. 1). Further, as shown in FIGS. 1 and 5, a receiving groove 53 (corresponding to the “receiving recess” of the present invention) extending in the vertical direction is formed on the front side of the front wall 51 </ b> B. 53, the stitched portion 15 of the skin material 10 is received. Thereby, it is suppressed that the stitching | suture part 15 of the skin material 10 bulges to the front side.

ここで、表皮材１０のうち前面壁５１Ｂを覆う部分（以下、「前面カバー部１０Ｚ」という）の長さは、前面壁５１Ｂの高さよりも長くなっていて、基材５１の表側面５１Ｍが表皮材１０で覆われると、図５及び図６（Ａ）に示すように、前面カバー部１０Ｚの下端部が前面壁５１Ｂよりも下方に飛び出る。そして、前面カバー部１０Ｚの下端部から、ストラップ２０がさらに下方に飛び出た格好となる。   Here, the length of the portion of the skin material 10 covering the front wall 51B (hereinafter referred to as “front cover portion 10Z”) is longer than the height of the front wall 51B. When covered with the skin material 10, as shown in FIGS. 5 and 6A, the lower end portion of the front cover portion 10Z protrudes downward from the front wall 51B. And it becomes the appearance which the strap 20 protruded further downward from the lower end part of the front cover part 10Z.

表皮材１０が基材５１の表側面５１Ｍに宛がわれると、表皮材１０の下端部を基材５１の裏側へと折り返す。このとき、ストラップ２０をＬ型壁部５２の裏側に引き込むことで、図６（Ａ）から図６（Ｂ）への変化に示すように、表皮材１０の前面カバー部１０Ｚを前面壁５１Ｂの下端部を支点として折り曲げ、前面壁５１Ｂに巻きつける。すると、前面カバー部１０ＺがＬ型壁部５２の裏側へと折り返される。このように、本実施形態のアームレスト５０の製造方法では、ストラップ２０を基材５１の裏側へ引き込むことにより、表皮材１０の下端部を基材５１の裏側へ容易に折り返すことが可能となる。   When the skin material 10 is directed to the front side surface 51 </ b> M of the base material 51, the lower end portion of the skin material 10 is folded back to the back side of the base material 51. At this time, by pulling the strap 20 into the back side of the L-shaped wall portion 52, the front cover portion 10Z of the skin material 10 is attached to the front wall 51B as shown in the change from FIG. 6 (A) to FIG. 6 (B). The lower end is bent as a fulcrum and wound around the front wall 51B. Then, the front cover 10 </ b> Z is folded back to the back side of the L-shaped wall 52. Thus, in the manufacturing method of the armrest 50 of this embodiment, the lower end portion of the skin material 10 can be easily folded back to the back side of the base material 51 by pulling the strap 20 to the back side of the base material 51.

次いで、表皮材１０のうち基材５１の裏側に折り返された部分を、溶着やタッカー止め等によって基材５１に固定する。図６（Ｂ）には、表皮材１０がタッカー６１によって基材５１に固定される例が示されている。これにより、アームレスト５０が完成する。なお、ストラップ２０の延出部２０Ａは、基材５１の裏側に溶着やタッカー止め等によって固定されてもよいし、切除されてもよい。   Next, a portion of the skin material 10 that is folded back on the back side of the base material 51 is fixed to the base material 51 by welding, tackering, or the like. FIG. 6B shows an example in which the skin material 10 is fixed to the base material 51 by the tucker 61. Thereby, the armrest 50 is completed. The extended portion 20A of the strap 20 may be fixed to the back side of the base material 51 by welding, tackering, or the like, or may be cut off.

アームレスト５０の製造方法に関する説明は以上である。次に、本実施形態の表皮材１０及び表皮材１０を用いたアームレスト５０の製造方法の作用効果について説明する。   This completes the description of the method of manufacturing the armrest 50. Next, the effect of the skin material 10 of this embodiment and the manufacturing method of the armrest 50 using the skin material 10 will be described.

本実施形態のアームレスト５０の製造方法では、表皮材１０を基材５１の表側面５１Ｍに宛がい、基材５１から飛び出した表皮材１０の下端部を基材５１の裏側へ折り返して固定することでアームレスト５０が得られる。ここで、基材５１には、表側が凸となるようにＬ字状に折り曲げられたＬ型壁部５２が形成され、このＬ型壁部５２の折り目を横切るように縫合部１５が配置されるため、縫合部１５の基材５１からの浮き上がりが問題となり得る。しかしながら、本実施形態の表皮材１０では、縫合部１５に共縫いされると共に、表皮片１１，１１同士の縫い目１３Ｌに沿って表皮片１１の外側へ延出する帯状のストラップ２０を備えているので、ストラップ２０をＬ型壁部５２の裏側に引き込むことで、表皮材１０の下端部をＬ型壁部５２の下端部に巻きつけるようにしてＬ型壁部５２の裏側へ折り返すことが可能となる。即ち、本実施形態では、縫合部１５に縫い付けられたストラップ２０を引っ張ることで、縫合部１５の基材５１（Ｌ型壁部５２）からの浮き上がりを抑えることが可能となる。しかも、ストラップ２０を基材５１（Ｌ型壁部５２）の裏側へ引き込むだけで、表皮材１０の折り返しが可能となるので、作業性の向上が図られる。   In the manufacturing method of the armrest 50 of the present embodiment, the skin material 10 is directed to the front side surface 51M of the base material 51, and the lower end portion of the skin material 10 protruding from the base material 51 is folded back and fixed to the back side of the base material 51. Thus, the armrest 50 is obtained. Here, the base 51 is formed with an L-shaped wall portion 52 that is bent in an L shape so that the front side is convex, and the stitching portion 15 is disposed so as to cross the fold of the L-shaped wall portion 52. Therefore, the lifting of the stitched portion 15 from the base material 51 can be a problem. However, the skin material 10 of the present embodiment includes a belt-like strap 20 that is sewn together with the stitching portion 15 and extends to the outside of the skin piece 11 along the seam 13L between the skin pieces 11 and 11.
