図１は、本発明の実施形態を説明するための、車両用シートの一例を示す。 FIG. 1 shows an example of a vehicle seat for explaining an embodiment of the present invention.

図１に示す車両用シート１は、座面部分を構成するシートクッション２と、背もたれ部分を構成するシートバック３と、シートに着席した乗員の頭部を支持するヘッドレスト４とを備える。シートクッション２及びシートバック３並びにヘッドレスト４は、例えばウレタンフォームなどの発泡材からなるクッションパッド、及びクッションパッドを支持するフレームをそれぞれ有する。 The vehicle seat 1 shown in FIG. 1 includes a seat cushion 2 that constitutes a seat surface portion, a seat back 3 that constitutes a backrest portion, and a headrest 4 that supports the head of an occupant seated on the seat. The seat cushion 2, the seat back 3, and the headrest 4 each have a cushion pad made of a foam material such as urethane foam, and a frame that supports the cushion pad.

シートクッション２のクッションパッド及びシートバック３のクッションパッドは、トリムカバー５によって一体に覆われており、ヘッドレスト４のクッションパッドもまた、トリムカバー５とは別のトリムカバーによって覆われている。 The cushion pad of the seat cushion 2 and the cushion pad of the seat back 3 are integrally covered by the trim cover 5, and the cushion pad of the headrest 4 is also covered by a trim cover different from the trim cover 5.

なお、シートクッション２のクッションパッド及びシートバック３のクッションパッドは、個別のトリムカバーによってそれぞれ覆われていてもよく、また、ヘッドレスト４が固定式のヘッドレストであってシートバック３と一体に構成される場合などには、ヘッドレスト４のクッションパッドは、一つのトリムカバーによって、シートバック３のクッションパッドと一体に覆われ、又はシートクッション２のクッションパッド及びシートバック３のクッションパッドと一体に覆われていてもよい。 The cushion pad of the seat cushion 2 and the cushion pad of the seat back 3 may be covered with individual trim covers, and the headrest 4 is a fixed headrest and is integrally formed with the seat back 3. In such cases, the cushion pad of the headrest 4 is integrally covered with the cushion pad of the seat back 3 or integrally with the cushion pad of the seat cushion 2 and the cushion pad of the seat back 3 by one trim cover. May be.

トリムカバー５は複数の表皮材が接ぎ合わされてなり、表皮材としては、例えば皮革（天然皮革、合成皮革）又は布帛（織物、編物、不織布）が用いられる。表皮材は、皮革又は布帛の単層構造であってもよいし、皮革又は布帛を表地として、皮革又は布帛にワディング（例えば弾性変形可能な軟質ポリウレタンフォームなどの樹脂発泡体）が積層された多層構造であってもよい。そして、トリムカバー５は、一種の表皮材によって形成されてもよいし、部位に応じて異なる複数種の表皮材によって形成されてもよい。 The trim cover 5 is formed by joining a plurality of skin materials, and as the skin material, for example, leather (natural leather, synthetic leather) or cloth (woven fabric, knitted fabric, non-woven fabric) is used. The skin material may have a single-layer structure of leather or cloth, or a multi-layer structure in which leather or cloth is used as the outer material and wading (for example, a resin foam such as elastically deformable flexible polyurethane foam) is laminated on the leather or cloth. It may be a structure. The trim cover 5 may be formed of one type of skin material, or may be formed of a plurality of different types of skin material depending on the site.

トリムカバー５を形成する複数の表皮材のうち、接ぎ合わされた二枚の表皮材１０，１１は、シートバック３の前面の幅方向中央部分を覆っている表皮材であり、表皮材１０，１１には表皮材１０，１１の接ぎ合せ方向（表皮材１０，１１の並び方向）に繰り返される模様がそれぞれ形成されている。 Of the plurality of skin materials forming the trim cover 5, the two joined skin materials 10 and 11 are skin materials covering the central portion of the front surface of the seat back 3 in the width direction, and the skin materials 10 and 11 A pattern that is repeated in the joining direction of the skin materials 10 and 11 (the direction in which the skin materials 10 and 11 are arranged) is formed.

図２及び図３は、表皮材１０，１１それぞれの模様の構成を示す。 2 and 3 show the composition of the patterns of the skin materials 10 and 11, respectively.

図示の例では、表皮材１０，１１それぞれに複数のステッチ１２が形成されており、複数のステッチ１２は、接ぎ合わせ方向に対して一方側に斜いて直線状に且つ互いに並行して延びるステッチの群と、接ぎ合わせ方向に対して他方側に斜いて直線状に且つ互いに並行して延びるステッチの群とを含む。これら二つのステッチ群が網目状に交差することによって、表皮材１０，１１の接ぎ合せ方向に繰り返される網目状の模様が構成されている。なお、表皮材１０，１１それぞれの模様及び模様を構成するステッチ１２のパターンは図示の例に限られるものではない。 In the illustrated example, a plurality of stitches 12 are formed on each of the skin materials 10 and 11, and the plurality of stitches 12 are stitches that are inclined to one side with respect to the joining direction and extend linearly and in parallel with each other. It includes a group and a group of stitches extending linearly and parallel to each other at an angle to the other side with respect to the joining direction. By intersecting these two stitch groups in a mesh pattern, a mesh pattern that is repeated in the joining direction of the skin materials 10 and 11 is formed. The patterns of the skin materials 10 and 11 and the patterns of the stitches 12 constituting the patterns are not limited to the illustrated examples.

複数のステッチ１２は接ぎ合わされる表皮材１０，１１それぞれの縫い代１０ａ，１１ａに達しており、縫い代１０ａ，１１ａに形成されている複数のステッチ１２の端部１２ａは、縫い代１０ａ，１１ａの延在方向に同一のパターンにて並んでいる。表皮材１０，１１は、複数のステッチ１２の端部１２ａを合わせ、表皮材１０，１１の接ぎ目１３を跨いでステッチ１２が連続するように接ぎ合わされている。 The plurality of stitches 12 reach the seam allowances 10a and 11a of the skin materials 10 and 11 to be joined, respectively, and the end portions 12a of the plurality of stitches 12 formed in the seam allowances 10a and 11a extend the seam allowances 10a and 11a. They are lined up in the same pattern in the direction. The skin materials 10 and 11 are joined so that the ends 12a of the plurality of stitches 12 are aligned and the stitches 12 are continuous so as to straddle the joint 13 of the skin materials 10 and 11.

そして、図３に示すように、複数のステッチ１２が、端部１２ａを除き、表皮材１０，１１の接ぎ合わせ方向に対して傾いて延びているのに対し、端部１２ａは、表皮材１０，１１の接ぎ合わせ方向と平行に直線状に延びている。 Then, as shown in FIG. 3, the plurality of stitches 12 extend at an angle with respect to the joining direction of the skin materials 10 and 11 except for the end portion 12a, whereas the end portion 12a has the skin material 10 , 11 extends in a straight line parallel to the joining direction.

図４及び図５は、表皮材１０，１１が接ぎ合わせ方向に相互に位置ずれして接ぎ合わされた場合を示す。 4 and 5 show a case where the skin materials 10 and 11 are misaligned with each other in the joining direction and joined together.

図４は、表皮材１０，１１それぞれの複数のステッチ１２の端部１２ａが表皮材１０，１１の接ぎ合わせ方向と平行に直線状に延びている場合を示しており、端部１２ａの一部が表皮材１０，１１の接ぎ目１３に現れるものの、接ぎ目１３を跨いでステッチ１２の連続性は保たれている。 FIG. 4 shows a case where the end portions 12a of the plurality of stitches 12 of the skin materials 10 and 11 extend linearly in parallel with the joining direction of the skin materials 10 and 11, and is a part of the end portions 12a. Appears at the joints 13 of the skin materials 10 and 11, but the continuity of the stitches 12 is maintained across the joints 13.

一方、図５は、表皮材１０，１１それぞれの複数のステッチ１２が末端まで表皮材１０，１１の接ぎ合わせ方向に対して傾いて延びている場合を示しており、表皮材１０，１１の接ぎ合わせ方向の相互の位置ずれに起因して、表皮材１０，１１の接ぎ目１３においてステッチ１２の齟齬が生じ、接ぎ目１３を境にステッチ１２が不連続となる。 On the other hand, FIG. 5 shows a case where a plurality of stitches 12 of the skin materials 10 and 11 extend to the end at an angle with respect to the joining direction of the skin materials 10 and 11, and the joints of the skin materials 10 and 11 are joined. Due to the mutual misalignment in the mating direction, the stitches 12 are inconsistent at the joints 13 of the skin materials 10 and 11, and the stitches 12 become discontinuous at the joints 13.

なお、表皮材１０，１１が接ぎ合せ方向に相互に位置ずれして接ぎ合わされるものとしたが、表皮材１０，１１の接ぎ合せ方向の相互の位置ずれは、表皮材１０，１１を接ぎ合せる縫い目が表皮材１０，１１において接ぎ合せ方向に位置ずれすることに等しく、したがって、表皮材１０，１１を接ぎ合せる縫い目が位置ずれした場合にも、ステッチ１２の端部１２ａが表皮材１０，１１の接ぎ合わせ方向と平行に直線状に延びていれば、ステッチ１２の連続性は保たれる。 It is assumed that the skin materials 10 and 11 are joined together with their positions displaced from each other in the joining direction, but the mutual misalignment of the skin materials 10 and 11 in the joining direction causes the skin materials 10 and 11 to be joined together. Equivalent to the seams being misaligned in the skin materials 10 and 11 in the joining direction, and therefore even if the seams that join the skin materials 10 and 11 are misaligned, the ends 12a of the stitch 12 will be displaced in the skin materials 10 and 11. The continuity of the stitch 12 is maintained as long as it extends linearly in parallel with the joining direction of the stitch 12.

このように、表皮材１０，１１それぞれの縫い代１０ａ，１１ａに形成されている複数のステッチ１２の端部１２ａが、縫い代１０ａ，１１ａの延在方向に同一のパターンにて並んでおり、且つ表皮材１０，１１の接ぎ合わせ方向と平行に直線状に延びていることにより、表皮材１０，１１の相互の位置ずれや縫い目の位置ずれによってもステッチ１２の連続性を保つことができ、トリムカバー５及び車両用シート１の意匠性を高めることができる。 In this way, the end portions 12a of the plurality of stitches 12 formed in the seam allowances 10a and 11a of the skin materials 10 and 11 are arranged in the same pattern in the extending direction of the seam allowances 10a and 11a, and the skin. Since the materials 10 and 11 extend linearly in parallel with the joining direction, the continuity of the stitch 12 can be maintained even if the skin materials 10 and 11 are displaced from each other or the seams are displaced, and the trim cover can be maintained. The design of 5 and the vehicle seat 1 can be enhanced.

ここまで、表皮材１０，１１それぞれの模様が複数のステッチ１２によって構成されるものとして説明したが、模様を構成する要素は、図６に示すエンボス１４や、図７に示すプリント１５であってもよい。いずれも、模様を構成する要素（エンボス１４又はプリント１５）が、少なくとも縫い代１０ａ，１１ａにおいて、縫い代１０ａ，１１ａの延在方向に同一のパターンにて並んでおり、且つ表皮材１０，１１の接ぎ合わせ方向と平行に延びており、表皮材１０，１１が接ぎ合わされた際に、表皮材１０，１１の接ぎ目を跨いで要素の連続性が保たれる。 Up to this point, the patterns of the skin materials 10 and 11 have been described as being composed of a plurality of stitches 12, but the elements constituting the patterns are the emboss 14 shown in FIG. 6 and the print 15 shown in FIG. May be good. In each case, the elements (embossing 14 or print 15) constituting the pattern are arranged in the same pattern in the extending direction of the seam allowances 10a and 11a at least in the seam allowances 10a and 11a, and the skin materials 10 and 11 are joined. It extends parallel to the mating direction, and when the skin materials 10 and 11 are joined, the continuity of the elements is maintained across the joints of the skin materials 10 and 11.
