Description

座席装置及び座席装置の製造方法Seat device and method of manufacturing seat device
  本発明は、椅子の表面を布や皮等の表皮材で被覆した椅子に関し、例えば、自動車用のシート（座席装置）に関するものである。 発 明 The present invention relates to a chair in which the surface of the chair is covered with a skin material such as cloth or leather, and relates to a seat (seat device) for an automobile, for example.
  例えば、自動車用のシートは、弾性を有するウレタン等で構成されるパッドを、シートカバーで被覆し保護するように形成することが多い。シートカバーは、通常、複数の表皮材が繋がるように縫合されて、袋状に形成される。この縫合の縫合せ部が形成する線は、ハギ線と呼ばれ、例えば、座席のシートクッションの着座面の側端に配置されるよう設定される。 For example, automobile seats are often formed by covering and protecting pads made of elastic urethane or the like with a seat cover. The seat cover is usually formed into a bag shape by stitching so that a plurality of skin materials are connected. A line formed by the stitched portion of the stitching is called a hooked line, and is set to be disposed at the side end of the seating surface of the seat cushion of the seat, for example.
  この縫合せ部には、玉縁（たまぶち）が設定されることもある。玉縁とは、別名、パイピングとも呼ばれ、美観を向上させるために、縫合わせ部に共縫いする飾り部材である。材料としては、例えば、柔軟性樹脂の押し出し成形材や、柔軟性樹脂芯材に表皮材を巻きつけたものが用いられる。 玉 A ball edge may be set on the stitched portion. The ball edge is also called aliasing, and is a decorative member that is sewn together at the stitched portion in order to improve the beauty. As the material, for example, an extrusion molding material of a flexible resin or a material in which a skin material is wound around a flexible resin core material is used.
  ところで、パッドは弾性を有するので、シートカバーの固定時における表皮テンションによって、ハギ線や玉縁が蛇行しやすい。ハギ線や玉縁が蛇行すると、見栄えが悪くなる。また、シートの部位によっては、乗降耐久性が求められることから、更にテンションが強くなり、蛇行が顕著化する。 By the way, since the pad has elasticity, the hail line and the rim are likely to meander due to the skin tension when the seat cover is fixed.

（本発明の実施形態）
  本発明の実施形態について説明する。
  図１は、本発明の実施形態に係る座席装置の斜視図である。本実施形態の座席装置１０は、自動車用のシートであり、図１に示すように、着座者が腰を下ろすシートクッション（着座部）１と、着座者の背もたれとなるシートバック２と、着座者の頭部を支えるヘッドレスト３とを含むように構成される。 (Embodiment of the present invention)
An embodiment of the present invention will be described.
FIG. 1 is a perspective view of a seat device according to an embodiment of the present invention. The seat device 10 of the present embodiment is an automobile seat, and as shown in FIG. 1, a seat cushion (sitting part) 1 on which a seated person sits down, a seat back 2 that serves as a backrest of the seated person, and a seating And a headrest 3 that supports the person's head.
  シートクッション１は、弾性を有するウレタン等で構成されるパッド１３（図２参照）と、パッド１３を被覆し保護するシートカバー１ａとを含むように構成される。シートバック２とヘッドレスト３も、それぞれ、シートクッション１と同様に、弾性を有するパッド（不図示）をシートカバー（不図示）で被覆し保護するように形成される。 The heel seat cushion 1 is configured to include a pad 13 (see FIG. 2) made of elastic urethane or the like, and a seat cover 1 a that covers and protects the pad 13. Similarly to the seat cushion 1, the seat back 2 and the headrest 3 are each formed so as to cover and protect an elastic pad (not shown) with a seat cover (not shown).
  シートカバーは、複数の表皮材が繋がるように縫合されて、凸状又は袋状に形成される。表皮材と表皮材の縫合せ部であるハギ線は、シートカバーにおいて、シートクッション１の着座面と側面（第１の側面）との境界や、シートバック２の背もたれ面と側面（第２の側面）との境界や、ヘッドレスト３の頭支面と側面（第３の側面）との境界に配置される。頭支面とは、頭部を支える面である。上記第１～第３の側面は、それぞれ、着座面、背もたれ面、頭支面に略垂直な面である。表皮材の材質は、例えば化学繊維や人工皮革や本皮であり、厚さは０．７～２.０ｍｍ程度である。 The heel sheet cover is sewn so that a plurality of skin materials are connected, and is formed in a convex shape or a bag shape. In the seat cover, the hook line that is the stitched portion between the skin material and the skin material is the boundary between the seating surface and the side surface (first side surface) of the seat cushion 1, the backrest surface and the side surface (second surface) of the seat back 2. And the boundary between the head support surface and the side surface (third side surface) of the headrest 3. The head support surface is a surface that supports the head. The first to third side surfaces are surfaces substantially perpendicular to the seating surface, the backrest surface, and the head support surface, respectively. The material of the skin material is, for example, chemical fiber, artificial leather, or real leather, and the thickness is about 0.7 to 2.0 mm.
  図１の例では、シートクッション１のシートカバー１ａにはハギ線１ｈ、シートバック２のシートカバーにはハギ線２ｈ、ヘッドレスト３のシートカバーにはハギ線３ｈが形成されている。ハギ線１ｈは、シートクッション１の着座面の端を、左側の後部から前部へ延び、前側の左端から右端へ延び、右側の前部から後部へ延びている。ハギ線２ｈは、シートバック２の背もたれ面の端を、左側の下部から上部へ延び、上側の左端から右端へ延び、右側の上部から下部へ延びている。ハギ線３ｈは、ヘッドレスト３の頭支面の端を、左側の下部から上部へ延び、上側の左端から右端へ延び、右側の上部から下部へ延びている。ここで、左右上下は、シートクッション１に着座した運転者から見た方向である。 In the example of FIG. 1, a hail wire 1 h is formed on the seat cover 1 a of the seat cushion 1, a hail wire 2 h is formed on the seat cover of the seat back 2, and a hail wire 3 h is formed on the seat cover of the headrest 3. The hail line 1h extends from the rear part on the left side to the front part, extends from the left part on the front side to the right part, and extends from the front part on the right side to the rear part. The hail line 2h extends the end of the backrest surface of the seat back 2 from the lower part on the left side to the upper part, extends from the upper left end to the right end, and extends from the upper part on the right side to the lower part. The hail line 3h extends from the lower part on the left side to the upper part, extends from the upper left end to the right end, and extends from the upper part on the right side to the lower part. Here, right and left and up and down are directions viewed from the driver seated on the seat cushion 1.
（第１実施例）
  次に、本実施形態の第１実施例に係る座席装置について説明する。図２は、第１実施例に係る座席装置の構造を示す図であり、図１のシートクッション１のハギ線１ｈに対する垂直断面（Ａ-Ａ断面）を示す図である。シートバック２のハギ線２ｈに対する垂直断面やヘッドレスト３のハギ線３ｈに対する垂直断面も同様の構造である。 (First embodiment)
Next, a seat device according to a first example of the present embodiment will be described. FIG. 2 is a view showing the structure of the seat device according to the first embodiment, and is a view showing a vertical cross section (AA cross section) with respect to the hook line 1h of the seat cushion 1 of FIG. The vertical cross section of the seat back 2 with respect to the hail line 2h and the vertical cross section of the headrest 3 with respect to the hail line 3h have the same structure.
  図２に示すように、ハギ線１ｈにおいて、シートクッション１内部のパッド１３には、芯材１１を収容するためのスリット１２が、シートクッション１の表面に対し略垂直方向に設けられている。スリット１２は、上記垂直方向に対し４５度以内とするのが、ハギ線の蛇行を抑制するうえで好ましい。図２では、スリット１２は、解り易いように、実際よりも大きく誇張して描かれているが、本実施形態では、パッド１３に設けられた切り込みである。例えば、スリット１２は、パッド１３をカッターナイフのような薄刃で切ることにより形成される。なお、スリット１２を、芯材１１と嵌め合う所定の幅を有する溝として形成することも可能である。 As shown in FIG. 2, in the hook wire 1 h, the pad 13 inside the seat cushion 1 is provided with a slit 12 for accommodating the core material 11 in a direction substantially perpendicular to the surface of the seat cushion 1. The slit 12 is preferably within 45 degrees with respect to the vertical direction in order to suppress the meandering of the hail line. In FIG. 2, the slit 12 is exaggerated larger than the actual one so as to be easily understood, but in the present embodiment, the slit 12 is a cut provided in the pad 13. For example, the slit 12 is formed by cutting the pad 13 with a thin blade such as a cutter knife. Note that the slit 12 may be formed as a groove having a predetermined width that fits with the core material 11.
  図２の例では、スリット１２の深さ（図２のｘ１ｘ２方向の長さ）は、芯材１１のシートクッション１内における深さ方向（図２のｘ１ｘ２方向）の長さＬ１（３～２０ｍｍ）よりも長い。この長さの差は、２～１０ｍｍ程度が好ましい。スリット１２の長さを芯材１１の長さよりも長くすることにより、シートクッション１が縮む方向に変形した場合に、芯材１１がパッド１３とぶつかり図２のｘ１方向に押し出されることが抑制できる。 In the example of FIG. 2, the depth of the slit 12 (the length in the x1 × 2 direction in FIG. 2) is the length L1 (3 to 20 mm) in the depth direction (the x1 × 2 direction in FIG. 2) in the seat cushion 1 of the core material 11. ) Longer than. The difference in length is preferably about 2 to 10 mm. By making the length of the slit 12 longer than the length of the core material 11, when the seat cushion 1 is deformed in the contracting direction, the core material 11 can be prevented from colliding with the pad 13 and being pushed out in the x1 direction of FIG. 2. .
  芯材１１は、ＰＰ（ポリプロピレン）等の柔軟性樹脂で形成される。芯材１１のシートクッション１内における深さ方向の長さＬ１は、上述したように３～２０ｍｍである。長さＬ１を３～２０ｍｍとすることにより、クッション１の柔軟性を損ねることを抑制しつつ、ハギ線が蛇行することを抑制できる。長さＬ１が長すぎると、クッション１の柔軟性を損ね、短すぎると、ハギ線が蛇行し易くなる。 The core material 11 is made of a flexible resin such as PP (polypropylene). The length L1 in the depth direction in the seat cushion 1 of the core material 11 is 3 to 20 mm as described above. By setting the length L1 to 3 to 20 mm, it is possible to suppress meandering of the hook wire while suppressing the loss of flexibility of the cushion 1. If the length L1 is too long, the flexibility of the cushion 1 is impaired. If the length L1 is too short, the hail line tends to meander.
  また、芯材１１のシートクッション１外におけるｘ１ｘ２方向の長さは、後述する凸部の高さ（ｘ１ｘ２方向の長さ）Ｌ２と略同じであり、例えば２～１０ｍｍである。この長さは、芯材１１と後述する表皮材１４及び表皮材１５とを、縫糸１７で縫い合わせるときの縫い代に必要な長さを、少なくとも含む。芯材１１の厚さｔ（図２のｙ１ｙ２方向の長さ）は、本実施例では、０．８～１．０ｍｍである。 The length of the core material 11 in the x1x2 direction outside the seat cushion 1 is substantially the same as the height (length in the x1x2 direction) L2 of a convex portion described later, for example, 2 to 10 mm. This length includes at least a length necessary for a seam allowance when the core material 11 and the skin material 14 and the skin material 15 described later are stitched together with the sewing thread 17. The thickness t of the core material 11 (the length in the y1y2 direction in FIG. 2) is 0.8 to 1.0 mm in this embodiment.
  芯材１１は、図２のｘｙ面（ｘ１ｘ２線及びｙ１ｙ２線を含む平面）と垂直な方向であるｚ方向に、略（Ｌ１＋Ｌ２）の幅で延びる長方形の形状である。芯材１１のｚ方向の長さは、例えば、図１に示すハギ線１ｈの長さであり、ｘ１ｘ２方向の長さよりも長い。このように、芯材１１は、シートクッション１の表面からパッド１３の方向に突出する板状部材である。 The core material 11 has a rectangular shape extending in the z direction which is a direction perpendicular to the xy plane (a plane including the x1x2 line and the y1y2 line) in FIG. 2 with a width of approximately (L1 + L2). The length of the core material 11 in the z direction is, for example, the length of the hail line 1h shown in FIG. 1, and is longer than the length in the x1x2 direction. Thus, the core material 11 is a plate-like member that protrudes from the surface of the seat cushion 1 toward the pad 13.
  なお、芯材１１は、ｚ方向における複数個所において、ｘ１ｘ２方向に亘る切れ目を設けるように構成してもよい。あるいは、芯材１１のパッド１３内の部分を、ｚ方向において、断続的に設けるように構成してもよい。この場合も、後述する凸部と凸部カバー１６は、ｚ方向に連続して形成される。 It should be noted that the core material 11 may be configured to provide cuts extending in the x1x2 direction at a plurality of locations in the z direction. Or you may comprise so that the part in the pad 13 of the core material 11 may be intermittently provided in az direction. Also in this case, the convex part and convex part cover 16 which are mentioned later are formed continuously in the z direction.
  また、芯材１１の表面には、芯材１１がパッド１３から抜けることを抑制するための抜け抑制部である凹凸（例えば、サメ肌状の凹凸）が形成されることが好ましい。抜け抑制部として、芯材１１をパッド１３の深さ方向、つまり、シートカバー１ａの内側方向（ｘ２方向）にのみ移動可能とする鉤部を設けてもよい。 In addition, the surface of the core material 11 is preferably formed with unevenness (for example, a shark skin-shaped unevenness) that is a disengagement suppressing portion for suppressing the core material 11 from being removed from the pad 13. You may provide the collar part which can move the core material 11 only to the depth direction of the pad 13, ie, the inner side direction (x2 direction) of the seat cover 1a, as a slip-off suppression part.
  図２に示すように、芯材１１の端部は、第１の表皮材１４の端部及び第２の表皮材１５の端部と、シートカバー１ａの外側（つまり、第１の表皮材１４及び第２の表皮材１５の外側）において、縫糸１７により縫い合わされている。そして、第１の表皮材１４の端部と第２の表皮材１５の端部と芯材１１の端部とにより、シートカバー１ａの外側方向（ｘ１方向）に突き出る凸部が形成されている。なお、芯材１１の端部とは、芯材１１のｘ１ｘ２方向における長さを３等分したときに、中央部以外の部分を指す。 As shown in FIG. 2, the end portion of the core material 11 includes the end portion of the first skin material 14 and the end portion of the second skin material 15, and the outside of the seat cover 1 a (that is, the first skin material 14. And on the outer side of the second skin material 15). And the convex part which protrudes in the outer side direction (x1 direction) of the seat cover 1a is formed by the edge part of the 1st skin material 14, the edge part of the 2nd skin material 15, and the edge part of the core material 11. . In addition, the edge part of the core material 11 points out parts other than a center part, when the length in the x1x2 direction of the core material 11 is divided into 3 equal parts.
  また、上記凸部の表面には、上記凸部を覆う凸部カバー１６が、設けられ取り付けられている。凸部カバー１６は、その両端が凸部カバー１６の内側となるように折り返され、該折り返された２つの端部が、上記凸部の側面（ｙ１ｙ２方向を向く面）に接触して、上記縫糸１７の位置よりもｘ１方向にずれた位置において、縫糸１８により上記凸部と縫い合わされている。なお、図２では、解り易くするため、縫糸１８が凸部カバー１６の表面より上にあるように描いているが、実際には、縫糸１８は凸部カバー１６の表面より沈んだ位置となる。縫糸１７や縫糸１８の材質は、例えば木綿や化学繊維である。 Moreover, the convex part cover 16 which covers the said convex part is provided and attached to the surface of the said convex part. The convex cover 16 is folded back so that both ends thereof are inside the convex cover 16, and the two folded end portions are in contact with the side surfaces (surfaces facing the y1y2 direction) of the convex portion, At the position shifted in the x1 direction from the position of the sewing thread 17, it is sewn to the convex portion by the sewing thread 18. In FIG. 2, for ease of understanding, the sewing thread 18 is drawn so as to be above the surface of the convex cover 16, but in actuality, the sewing thread 18 is in a position sunk from the surface of the convex cover 16. . The material of the sewing thread 17 and the sewing thread 18 is, for example, cotton or chemical fiber.
  凸部カバー１６を設けない構成とすることも可能であるが、凸部カバー１６を設けることにより、ハギ線１ｈの美観がより向上し、また、上記凸部の先端が解れることが抑制される。また、凸部カバー１６の両端を、凸部カバー１６の内側となるように折り返すことにより、ハギ線１ｈの美観がさらに向上する。 Although it is possible to adopt a configuration in which the convex portion cover 16 is not provided, the provision of the convex portion cover 16 further improves the aesthetic appearance of the hail line 1h and suppresses the unraveling of the tip of the convex portion. The Further, by folding back both ends of the convex cover 16 so as to be inside the convex cover 16, the appearance of the hail line 1h is further improved.
  なお、凸部カバー１６は、その両端を凸部カバー１６の内側となるように折り返さず、その両端を上記凸部と、縫糸１８により縫い合わすように構成することも可能である。このようにしても、ハギ線１ｈの美観が向上し、また、上記凸部の先端が解れることが抑制される。 It should be noted that the convex cover 16 may be configured such that both ends thereof are not folded back so as to be inside the convex cover 16 and both ends thereof are stitched together with the convex portion by the sewing thread 18. Even if it does in this way, the beauty | look of the hail line 1h will improve and it will be suppressed that the front-end | tip of the said convex part is released.
  また、凸部カバー１６内において、凸部カバー１６の先端１６ａ，１６ｂと、第１の表皮材１４の先端１４ａと、第２の表皮材１５の先端１５ａと、芯材１１の先端１１ａとを、シートカバー１ａの表面に対して平行としている。このように、凸部のｘ１方向の先端位置を揃えることにより、凸部カバー１６の表面の凹凸が軽減され、ハギ線１ｈの美観がさらに向上する。 Further, in the convex cover 16, the tips 16 a and 16 b of the convex cover 16, the tip 14 a of the first skin material 14, the tip 15 a of the second skin material 15, and the tip 11 a of the core material 11 are arranged. , And parallel to the surface of the seat cover 1a. As described above, by aligning the tip positions of the convex portions in the x1 direction, the unevenness of the surface of the convex portion cover 16 is reduced, and the appearance of the hail line 1h is further improved.
  次に、第１実施例に係る座席装置の製造方法の工程を説明する。
（ステップ１）
  まず、パッド１３に、芯材１１を収容するスリット１２を形成する。例えば、カッターナイフのような薄刃で、パッド１３に切り目を入れて、スリット１２を形成する。このとき、スリット１２のｘ１ｘ２方向の長さを、上記Ｌ１より長くするのが好ましい。 Next, the steps of the seat device manufacturing method according to the first embodiment will be described.
(Step 1)
First, the slit 12 for accommodating the core material 11 is formed in the pad 13. For example, the slit 12 is formed by making a cut in the pad 13 with a thin blade such as a cutter knife. At this time, it is preferable that the length of the slit 12 in the x1x2 direction is longer than the length L1.
（ステップ２）
  複数の表皮材を繋ぐように縫い合わせて、シートカバー１ａを形成する。このとき、ハギ線１ｈに該当する表皮材の縫い目において、パッド１３の方向（シートカバー１ａの内側方向：ｘ２方向）に突出するように、芯材１１を取り付け縫い合わせる。なお、ステップ１とステップ２は、どちらが先でもよい。 (Step 2)
The seat cover 1a is formed by stitching together a plurality of skin materials. At this time, the core material 11 is attached and sewn so as to protrude in the direction of the pad 13 (inner direction of the seat cover 1a: x2 direction) at the seam of the skin material corresponding to the hail line 1h. Either step 1 or step 2 may be performed first.
（ステップ２ａ）
  詳しくは、第１の表皮材１４の端部と、第２の表皮材１５の端部と、芯材１１の端部とを、まとめて、シートカバー１ａの外側において、縫糸１７により縫い合わせる。これにより、第１の表皮材１４の端部と第２の表皮材１５の端部と芯材１１の端部とにより、凸部を形成する。また、このとき、第１の表皮材先端１４ａと、第２の表皮材先端１５ａと、芯材先端１１ａとは、シートカバー１ａの表面から同じ位置となるように、揃えられる。つまり、第１の表皮材先端１４ａと、第２の表皮材先端１５ａと、芯材先端１１ａとが、シートカバー１ａの表面に対して平行となる。このとき、芯材１１は、シートカバー１ａの表面から内側方向に突出している。 (Step 2a)
Specifically, the end portion of the first skin material 14, the end portion of the second skin material 15, and the end portion of the core material 11 are collectively stitched together with the sewing thread 17 outside the seat cover 1 a. Thus, a convex portion is formed by the end portion of the first skin material 14, the end portion of the second skin material 15, and the end portion of the core material 11. At this time, the first skin material tip 14a, the second skin material tip 15a, and the core material tip 11a are aligned so as to be at the same position from the surface of the seat cover 1a. That is, the first skin material tip 14a, the second skin material tip 15a, and the core material tip 11a are parallel to the surface of the seat cover 1a. At this time, the core material 11 protrudes inward from the surface of the seat cover 1a.
（ステップ２ｂ）
  次に、凸部を、凸部カバー１６で覆う。詳しくは、凸部カバー１６は、その両端が折り返され、該折り返された２つの端部が、第１の表皮材１４の端部、芯材１１の端部、及び第２の表皮材１５の端部と、まとめて縫糸１８により縫い合わされる。このとき、凸部カバー１６の両端は、第１の表皮材先端１４ａや第２の表皮材先端１５ａと、シートカバー１ａの表面から同じ位置となるように、揃えられる。 (Step 2b)
Next, the convex portion is covered with the convex portion cover 16. Specifically, both ends of the convex cover 16 are folded, and the two folded ends are the end of the first skin material 14, the end of the core material 11, and the second skin material 15. The end portions are sewn together by a sewing thread 18. At this time, both ends of the convex cover 16 are aligned with the first skin material tip 14a and the second skin material tip 15a so as to be at the same position from the surface of the seat cover 1a.
（ステップ３）
  シートカバー１ａに取り付けた芯材１１を、スリット１２に挿入するように、シートカバー１ａをパッド１３に取り付け、シートカバー１ａでパッド１３を被覆する。 (Step 3)
The seat cover 1a is attached to the pad 13 so that the core 11 attached to the seat cover 1a is inserted into the slit 12, and the pad 13 is covered with the seat cover 1a.
  第１実施例によれば、少なくとも以下に示す効果を奏する。

  （Ａ２）第１の表皮材の端部と、第２の表皮材の端部と、板状部材の端部とが、シートカバーの外側において縫い合わされて、第１の表皮材の端部と第２の表皮材の端部と板状部材の端部とにより、凸部が形成されるように構成したので、ハギ線の美観が向上する。
  （Ａ３）凸部を覆う凸部カバーを設けるように構成したので、凸部の先端が解れることが抑制され、また、ハギ線の美観がより向上する。
  （Ａ４）凸部カバーは、その両端が折り返され、該折り返された２つの端部が、第１の表皮材の端部、板状部材の端部、及び第２の表皮材の端部と、まとめて縫い合わされるように構成したので、ハギ線の美観がさらに向上する。
  （Ａ５）凸部カバー内において、凸部カバーの両端と、第１の表皮材の先端と、第２の表皮材の先端と、板状部材の先端とが、シートカバーの表面に対して平行となるように構成したので、ハギ線の美観がさらに向上する。
  （Ａ６）パッド内における板状部材の長さが３～２０ｍｍであるように構成したので、クッションの柔軟性を損ねることを抑制しつつ、ハギ線が蛇行することを抑制できる。
  （Ａ７）板状部材の表面に凹凸を形成するように構成したので、板状部材がパッドから抜けることを抑制できる。
  （Ａ８）スリットの深さ方向の長さは、板状部材の深さ方向の長さよりも長くなるように構成したので、板状部材がパッドから抜けることを抑制できる。 According to the first embodiment, at least the following effects can be obtained.
(A1) The seat cover is formed by stitching together a plurality of skin materials, and has a plate-like member (core material 11) protruding in the direction of the pad at the seam of the plurality of skin materials. Since it is configured to have a slit to be accommodated, it is possible to suppress the meander line from meandering. In addition, the seat cover can be easily attached to the pad.
(A2) The end of the first skin material, the end of the second skin material, the end of the plate-like member, and the end of the first skin material are sewn together outside the seat cover. Since it has constituted so that a convex part may be formed by the edge part of the 2nd skin material, and the edge part of a tabular member, the beauty of a hail line improves.
(A3) Since the convex cover that covers the convex portion is provided, the tip of the convex portion is prevented from being unraveled, and the appearance of the hooked line is further improved.
(A4) Both ends of the convex cover are folded, and the two folded ends are the end of the first skin material, the end of the plate member, and the end of the second skin material. Since it is configured to be sewn together, the appearance of the hail line is further improved.
