Description

本発明は、車両用シートのヘッドレストに係り、特に、発泡成形した部材の表面を表皮で覆った構成を有する車両用シートのヘッドレストに係る。 The present invention relates to a headrest of a vehicle seat, and more particularly to a headrest of a vehicle seat having a structure in which the surface of a foam-molded member is covered with a skin.

従来の車両用シートのヘッドレストとして、例えば特開２００７−１９５７６８号公報（特許文献１）には、袋状に縫製した表皮の開口部において、一方の側の端末部を折り返してその上に他方の側の端末部を重ね合わせることで、開口部の内側に３枚重ねの部分を形成する構成が開示されている。 As a headrest of a conventional vehicle seat, for example, in Japanese Patent Application Laid-Open No. 2007-195768 (Patent Document 1), in an opening of a skin sewn in a bag shape, a terminal portion on one side is folded back and the other portion is placed on the opening. A configuration is disclosed in which a three-layered portion is formed inside the opening by overlapping the terminal portions on the side.

また、特開２０１６−１８２９０９号公報（特許文献２）には、１層構造の表皮を袋状に縫製した後、開口部に、この開口部の寸法よりも少し長い開口整形治具を挿入して、張力をかけることにより開口部を閉じた状態で、袋状の表皮の内部にウレタンを注入して発泡させることが記載されている。 Further, in Japanese Patent Application Laid-Open No. 2016-182909 (Patent Document 2), after sewing a one-layer structure skin into a bag shape, an opening shaping jig slightly longer than the size of the opening is inserted into the opening. It is described that urethane is injected into the inside of the bag-shaped epidermis and foamed in a state where the opening is closed by applying tension.

特開２００７−１９５７６８号公報JP-A-2007-195768 特開２０１６−１８２９０９号公報Japanese Unexamined Patent Publication No. 2016-182909

乗用車シートのヘッドレストの表皮が、第１層としての表面層と、ワディングなどで形成された第２層と、フィルムなどで形成された第３層を有する３層構造で形成されていた場合、表皮の剛性は、比較的高くなる。このような表皮を、特許文献１に記載されているように、袋状に縫製した表皮の開口部の内側に表皮の端末部を３枚重ねに形成すると、この３枚重ねにした部分は比較的高い剛性のために、隙間なくしっかりと重ね合わせられて、袋状の表皮の内部にウレタンを注入して発泡させるときに、開口部から外部に漏れ出ることが少ない。 When the skin of the headrest of a passenger car seat is formed of a three-layer structure having a surface layer as a first layer, a second layer formed by wading or the like, and a third layer formed of a film or the like, the skin is formed. Rigidity is relatively high. When such an epidermis is formed by forming three layers of epidermis terminal portions inside the opening of the epidermis sewn in a bag shape as described in Patent Document 1, the three-layered portion is compared. Due to its high rigidity, it is tightly stacked without gaps, and when urethane is injected into the inside of the bag-shaped skin and foamed, it is unlikely to leak to the outside through the opening.

しかし、特許文献２に記載されているように、ヘッドレストの表皮を１層構造にすると、開口部の内側に表皮の端末部を３枚重ねに形成しても十分な剛性を得ることができない。従って、表皮を１層構造にした場合、特許文献１に記載されているように、単に３枚重ねしただけの状態で、袋状に成形した表皮の内部にウレタンを注入して発泡させると、３枚重ねした部分の開口部から発泡したウレタンが外部に漏れ出てしまう恐れがある。 However, as described in Patent Document 2, when the skin of the headrest has a one-layer structure, sufficient rigidity cannot be obtained even if the end portions of the skin are formed in three layers inside the opening. Therefore, when the epidermis has a one-layer structure, as described in Patent Document 1, urethane is injected into the inside of the epidermis formed into a bag shape and foamed in a state where three sheets are simply stacked. There is a risk that urethane foamed from the opening of the three-ply stack will leak to the outside.

この発泡したウレタンが袋状に成形した表皮の外部へ漏れ出てしまうのを防ぐために、特許文献２では、開口寸法よりも少し長い開口整形治具を開口部に挿入して張力をかける方法を採っている。開口整形治具を用いて開口部を引張って閉じた状態にすることにより、袋状の表皮の内部に注入して発泡させたウレタンが袋状に成形した表皮の外部へ漏れ出すのを防止している。 In order to prevent the foamed urethane from leaking to the outside of the bag-shaped epidermis, Patent Document 2 describes a method in which an opening shaping jig slightly longer than the opening size is inserted into the opening to apply tension. I'm taking it. By pulling the opening to a closed state using an opening shaping jig, it is possible to prevent urethane that has been injected and foamed into the bag-shaped epidermis from leaking to the outside of the bag-shaped epidermis. ing.

しかし、特許文献２に記載されているように、開口寸法よりも少し長い開口整形治具を開口部に挿入するには、開口部を引張って開口整形治具を力尽くで開口部に挿入しなければならず、作業性が悪い。その結果、袋状に成形した表皮の内部にウレタンの注入を開始するまでに、比較的長い時間を要してしまう。 However, as described in Patent Document 2, in order to insert an opening shaping jig slightly longer than the opening size into the opening, the opening is pulled and the opening shaping jig is inserted into the opening with full force. It must be done, and workability is poor. As a result, it takes a relatively long time to start injecting urethane into the inside of the bag-shaped epidermis.

本発明は、上記した従来技術の課題を解決して、ヘッドレストの表皮を１層構造にした場合であっても、袋状に形成した表皮の内部にウレタンを注入して発泡させるときに、開口部から外部に漏れ出すのを比較的容易に防止できる構成を有するヘッドレストを提供するものである。 The present invention solves the above-mentioned problems of the prior art, and even when the skin of the headrest has a one-layer structure, it opens when urethane is injected into the inside of the skin formed in a bag shape and foamed. Provided is a headrest having a structure capable of relatively easily preventing leakage from a portion to the outside.

In order to solve the above-mentioned problems, in the present invention, the headrest of the vehicle seat is filled in the skin portion formed by superimposing the skin members and sewn into a bag shape and the inside of the sewn bag-shaped skin portion. It is composed of a urethane foam and a stay having a pair of legs extending from the inside of the urethane foam to the outside of the skin, and the skin is sewn to a part of a portion where the skin members are overlapped. The skin member has a non-sewn portion, and the skin member is the first section portion extending from the side of one skin member of the portion where the skin member is overlapped in this non-sewn portion and folded back inside the skin portion. The first portion extending from the side of the other epidermis member of the portion where the epidermis members are overlapped in the non-sewn portion and being overlapped with the first section portion inside the epidermis portion and along the folded direction. and a second section part near the end of the section portion and both sides are sewn in, the second piece portion is adhered to the foamed urethane, the second piece portion are formed holes The folded first section is adhered to urethane foam through a hole formed in the second section, and the second section is made of a urethane foam material inside the epidermis. A notch is formed for passing a nozzle for supplying the urethane, and a mesh-like cover is attached to a portion covering the notch .

本発明によれば、ヘッドレストの表皮を１層構造にした場合であっても、袋状の表皮の内部にウレタン発泡原液を注入して発泡させるときに、開口部から外部に漏れ出すのを比較的容易に防止でき、開口部の外観品質を損なうことなくヘッドレストを提供することが出来る。 According to the present invention, even when the skin of the headrest has a one-layer structure, when the urethane foam stock solution is injected into the bag-shaped skin and foamed, it is compared that it leaks to the outside from the opening. It can be easily prevented and the headrest can be provided without compromising the appearance quality of the opening.

本発明は、ヘッドレストの表皮を１層構造または発泡ウレタンと接する側に薄い樹脂層を形成した２層構造にした場合であっても、袋状に形成した表皮の内部にウレタン発泡原液を注入して発泡させるときに、袋状に形成した表皮の開口部から外部に発泡ウレタンが漏れ出すのを比較的容易に防止できるようにして、開口部の外観品質を損なうことなくヘッドレストを形成することが出来るようにしたものである。 In the present invention, even when the skin of the headrest has a one-layer structure or a two-layer structure in which a thin resin layer is formed on the side in contact with urethane foam, the urethane foam stock solution is injected into the bag-shaped skin. It is possible to form a headrest without impairing the appearance quality of the opening by making it relatively easy to prevent urethane foam from leaking to the outside from the opening of the epidermis formed in the shape of a bag when foaming. It is something that can be done.

即ち、本発明では、車両用シートのヘッドレストの表皮部を、表皮部材を重ね合わせた部分の一部に縫合されていない部分を有し、この縫合されていない部分において表皮部材を重ね合わせた部分の一方の表皮部材の側から伸びて縫合し袋状に形成した表皮部の内部で折り返された第１の切片部と、縫合されていない部分において表皮部材を重ね合わせた部分の他方の表皮部材の側から伸びて縫合し袋状に形成した表皮部の内部で第１の切片部と重ね合わされて折り返した方向に沿って第１の切片部と両側の端部付近が縫合された第２の切片部とを有し、第１の切片と第２の切片とを発泡ウレタンに接着することで、発泡ウレタンが開口部から外部に漏れ出すのを防止するようにしたものである。 That is, in the present invention, the skin portion of the headrest of the vehicle seat has a portion that is not sewn to a part of the portion where the skin members are overlapped, and the portion where the skin members are overlapped in this non-sewn portion. The first section portion that is folded back inside the epidermis portion that extends from the side of one epidermis member and is sewn into a bag shape, and the other epidermis member that is the portion where the epidermis member is overlapped in the unsewn portion. A second section in which the first section and the vicinity of both ends are sewn along the direction in which the first section is overlapped with the first section and folded back inside the epidermis formed by suturing from the side of the first section. It has a section portion, and by adhering the first section and the second section to the urethane foam, the urethane foam is prevented from leaking to the outside from the opening.

以下に、本発明の実施例を、図を用いて説明する。 Hereinafter, examples of the present invention will be described with reference to the drawings.

図１は、本実施例に係る車両用シートのヘッドレスト２００の斜視図を示す。図１に示した状態は、袋状に成形した表皮１００の内部にノズル１４０からウレタン発泡原液を注入して発泡させた直後の状態を示している。袋状に成形した表皮１００の内部にウレタン発泡原液を注入して発泡させる工程は、袋状に成形した表皮１００を図４に示すように金型の内部にセットした状態で行われる。 FIG. 1 shows a perspective view of a headrest 200 of a vehicle seat according to the present embodiment. The state shown in FIG. 1 shows a state immediately after the urethane foam stock solution is injected from the nozzle 140 into the inside of the bag-shaped skin 100 and foamed. The step of injecting the urethane foam stock solution into the bag-shaped skin 100 and foaming it is performed in a state where the bag-shaped skin 100 is set inside the mold as shown in FIG.

図１に示したヘッドレスト２００の構成において、１００は表皮で、織物又は編物、革、合成皮革などを材料として１層で構成されている。１１０と１２０とは、表皮１００を構成する部材であって、両側の縫合部２１０の線に沿って縫合されており、中央部分には縫合されていない開口部２２０が形成されている。 In the configuration of the headrest 200 shown in FIG. 1, 100 is an epidermis, which is composed of one layer made of woven fabric or knitted fabric, leather, synthetic leather, or the like. The 110 and 120 are members constituting the epidermis 100, and are sewn along the lines of the sewn portions 210 on both sides, and an unsewn opening 220 is formed in the central portion.

この縫合されていない開口部２２０は、表皮１００の部材である表皮部材１１０と１２０とを含む表皮部材を縫合した後に、この開口部２２０を通して表皮１００の裏と表をひっくり返すためのものである。なお、表皮１００は、図示した縫合部２１０以外の部分においても表皮部材が縫合されているが、説明を簡略化するために、図示を省略してある。 The unsewn opening 220 is for turning over the back and front of the epidermis 100 through the opening 220 after suturing the epidermis member including the epidermis members 110 and 120 which are the members of the epidermis 100. In the epidermis 100, the epidermis member is also sewn in a portion other than the illustrated suture portion 210, but the illustration is omitted for the sake of simplicity.

表皮１００の表皮部材１１０と１２０とを縫合(縫製)する前の状態を図２に示す。図２に示した状態で、表皮部材１１０は、図１に示したように成形された状態で表側になる面(表側の面)が上側になっている。一方、表皮部材１２０は、図１に示したように成形された状態で表側になる面(表側の面)が下側になっている。即ち、図２に示した状態で、表皮部材１１０と１２０とは、表側の面が互いに向き合った状態になっている。 FIG. 2 shows a state before the skin members 110 and 120 of the skin 100 are sewn (sewn). In the state shown in FIG. 2, the skin member 110 has a surface (front surface) on the upper side, which is the front side in the molded state as shown in FIG. On the other hand, the skin member 120 has a front surface (front surface) in a molded state as shown in FIG. 1 on the lower side. That is, in the state shown in FIG. 2, the skin members 110 and 120 are in a state where the front surfaces face each other.

表皮部材１１０には切片１１１が、また、表皮部材１２０には切片１２１が形成されている。表皮部材１１０と切片１１１には、ノズル１４０を通すための切り込み１４１と１４２とが形成されている。また、表皮部材１２０には、ノズル１４０を通すための切り込み１４３が形成されている。一方、表皮部材１１０には、ステー１３０の一対の脚部１３０ａと１３０ｂとを通すためのステー用穴１３１が２箇所に設けられている。 A section 111 is formed on the skin member 110, and a section 121 is formed on the skin member 120. The skin member 110 and the section 111 are formed with notches 141 and 142 for passing the nozzle 140. Further, the skin member 120 is formed with a notch 143 for passing the nozzle 140. On the other hand, the skin member 110 is provided with two stay holes 131 for passing the pair of leg portions 130a and 130b of the stay 130.

表皮部材１２０の側の切片１２１には、切り込み１４３の上を覆うようにして、粗い網目状の繊維(メッシュ)で形成されたカバー２３０が切片１２１に縫合又は接着により取り付けられている。また、切片１２１には、穴１２２が２箇所に形成されている。図２には、穴１２２を２箇所に形成した例を示したが、穴１２２の数は、１個であっても良いし、また、３個以上であっても良い。 On the section 121 on the side of the skin member 120, a cover 230 formed of coarse mesh fibers (mesh) is attached to the section 121 by suture or adhesion so as to cover the notch 143. Further, the section 121 is formed with holes 122 at two positions. Although FIG. 2 shows an example in which the holes 122 are formed at two positions, the number of holes 122 may be one or three or more.

また、本実施例では、図２に示すように、２つの穴１２２を、切り込み１４３を挟んで両側の対象な位置に配置することにより、開口部から外部への発泡ウレタンの漏れ出しを確実に防止するようにしている。 Further, in this embodiment, as shown in FIG. 2, by arranging the two holes 122 at the target positions on both sides of the notch 143, the urethane foam leaks from the opening to the outside reliably. I try to prevent it.

図２に示した構成で、表皮部材１１０と１２０とを、切り込み１４１と１４３とが重なり合うようにして重ね合せた状態で、縫合部２１０として一点差線で示した線に沿って縫製し縫合する。これにより、表皮部材１１０と１２０とを繋ぎ合わされて、表皮１００が袋状に成形される。この状態で、図２においてＬで示した区間は縫合されておらず、開口部２２０を形成する。２か所の穴１２２は、何れも開口部２２０の内側に形成されている。 In the configuration shown in FIG. 2, the skin members 110 and 120 are sewn and sewn along the line indicated by the one-point difference line as the suture portion 210 in a state where the cuts 141 and 143 are overlapped so as to overlap each other. .. As a result, the skin members 110 and 120 are joined together, and the skin 100 is formed into a bag shape. In this state, the section indicated by L in FIG. 2 is not sutured and forms an opening 220. The two holes 122 are both formed inside the opening 220.

実際には、表皮１００は、表皮部材１１０と１２０以外の表皮部材も縫製し繋ぎ合わされて袋状に形成されるが、本実施例では、説明を簡単にするために、表皮部材１１０と１２０とが繋ぎ合わされて表皮１００が袋状に成形されるとして説明する。 Actually, the skin 100 is formed in a bag shape by sewing and joining the skin members other than the skin members 110 and 120, but in this embodiment, for the sake of simplicity, the skin members 110 and 120 are combined with each other. Will be described as if the skin 100 is formed into a bag shape by being joined together.

表皮部材１１０と１２０とを縫合して袋状にし、表皮部材１１０と１２０との縫合された部分を縫合されていない開口部２２０を通すことで、表皮部材１１０と１２０とを裏返すことにより、図１に示したように、縫製時に互いに内側を向いていた表側の面が外側になる。その後、ステー１３０の一対の脚部１３０ａと１３０ｂとを２箇所のステー用穴１３１に通す。 The skin members 110 and 120 are sewn into a bag shape, and the sewn portion of the skin members 110 and 120 is passed through an unsewn opening 220, so that the skin members 110 and 120 are turned inside out. As shown in No. 1, the front side surfaces that face each other inward at the time of sewing become the outer side. After that, the pair of legs 130a and 130b of the stay 130 are passed through the two stay holes 131.

ここで、表皮部材１１０と１２０とを１層構造としたことにより、従来の表皮を３層で形成した場合と比べて、表皮１００の剛性を小さくする(柔軟にする)ことが出来る。その結果、縫合した表皮部材１１０と１２０とを裏返すときに、従来の剛性が大きい３層で形成した表皮の場合と比べて、表皮部材１１０と１２０とを通すための開口部２２０の幅Ｌを小さくすることができる。 Here, by forming the skin members 110 and 120 into a one-layer structure, the rigidity of the skin 100 can be reduced (made flexible) as compared with the case where the conventional skin is formed of three layers. As a result, when the sutured skin members 110 and 120 are turned inside out, the width L of the opening 220 for passing the skin members 110 and 120 is increased as compared with the case of the conventional skin formed of three layers having high rigidity. It can be made smaller.

具体的には、従来の３層で形成された表皮を用いた場合に、開口部２２０のＬの寸法として１２０ｍｍ前後必要であったのに対して、本実施例による１層で形成した表皮部材１１０と１２０とを通す場合には、５０から９０ｍｍ程度まで、好ましくは６０から８０ｍｍ程度までに小さくすることができる。 Specifically, when a conventional epidermis formed of three layers was used, the L dimension of the opening 220 was required to be about 120 mm, whereas the epidermis member formed of one layer according to this embodiment was required. When passing through 110 and 120, the size can be reduced to about 50 to 90 mm, preferably about 60 to 80 mm.

図３には、ノズル１４０を、切り込み１４１，１４２，１４３を通して、袋状に形成された表皮１００の内部(図３の下側)に挿入した状態を示す。これは、図１の袋状に形成された表皮１００の内部に発泡ウレタンを充填させる前におけるＡ−Ａ断面に相当する。 FIG. 3 shows a state in which the nozzle 140 is inserted into the inside of the bag-shaped skin 100 (lower side of FIG. 3) through the cuts 141, 142, and 143. This corresponds to the AA cross section before filling the inside of the bag-shaped skin 100 of FIG. 1 with urethane foam.

図３に示した状態は、縫合した表皮部材１１０と１２０とを開口部２２０を通して裏と表をひっくり返した後に、袋状に形成された表皮１００の内部で切片１１１と１２１とを表皮部材１１０の側に折り曲げて、ノズル１４０を切り込み１４２の側から切り込み１４１と１４３とに通して、表皮１００の内部に突き出させた状態を示している。この状態で、ノズル１４０の先端部分は、切片１２１に取り付けられたカバー２３０で覆われている。 In the state shown in FIG. 3, the sutured epidermis members 110 and 120 are turned upside down through the opening 220, and then the sections 111 and 121 are formed inside the epidermis 100 formed in a bag shape. The nozzle 140 is bent from the side of the notch 142 to the notches 141 and 143, and is projected into the skin 100. In this state, the tip portion of the nozzle 140 is covered with the cover 230 attached to the section 121.

ノズル１４０を、切り込み１４２の側から切り込み１４１と１４３とに通すために、縫合された切片１１１と１２１とを表皮部材１１０の側に折り曲げるときに、切片１１１と１２１にそれぞれ形成されて重ね合わされている切り込み１４１と１４３とが、表皮部材１１０に形成されている切り込み１４２と重なるようにして折り曲げる。 When the sutured sections 111 and 121 are bent toward the skin member 110 in order to pass the nozzle 140 from the side of the notch 142 through the notches 141 and 143, they are formed and overlapped on the sections 111 and 121, respectively. The cuts 141 and 143 are bent so as to overlap the cuts 142 formed in the skin member 110.

このノズル１４０が挿入され、ステー１３０を取り付けた、表皮部材１１０と１２０とで袋状に形成された表皮１００を、図４に示すように、金型３１１と３１２とに装着する。この状態で、図示していないウレタン発泡原液供給部からノズル１４０を介してウレタン発泡原液１５１を袋状に形成された表皮１００の内部に供給する。 As shown in FIG. 4, the skin 100 formed in a bag shape by the skin members 110 and 120 to which the nozzle 140 is inserted and the stay 130 is attached is attached to the molds 311 and 312. In this state, the urethane foam stock solution 151 is supplied from the urethane foam stock solution supply unit (not shown) to the inside of the skin 100 formed in a bag shape via the nozzle 140.

ウレタン発泡原液１５１は、ノズル１４０の先端部からある程度の勢い(噴射速度)を持って袋状に形成された表皮１００の内部に供給される。このとき、ノズル１４０の出口の直前にカバー２３０が無いと、ノズル１４０の先端部から勢いよく飛び出したウレタン発泡原液１５１は、表皮部材１１０又は１２０の一部に集中して吹き付けられ、ウレタン発泡原液１５１が表皮部材１１０又は１２０の一部に過度に浸み込んでしまう。表皮部材１１０又は１２０に過度に浸み込んだウレタン発泡原液１５１は、発泡せずに固まってしまい、本来柔らかい肌触りを有するヘッドレスト２００の触感を損ねてしまう。 The urethane foam stock solution 151 is supplied from the tip of the nozzle 140 to the inside of the skin 100 formed in a bag shape with a certain amount of momentum (injection speed). At this time, if the cover 230 is not provided immediately before the outlet of the nozzle 140, the urethane foam stock solution 151 that vigorously pops out from the tip of the nozzle 140 is concentrated on a part of the skin member 110 or 120 and is sprayed on the urethane foam stock solution. 151 excessively penetrates into a part of the skin member 110 or 120. The urethane foam stock solution 151 that has excessively soaked into the skin member 110 or 120 solidifies without foaming, and impairs the tactile sensation of the headrest 200, which originally has a soft touch.

これに対して、本実施例では、ノズル１４０から勢いよく飛び出したウレタン発泡原液１５１は、ノズル１４０の先端部分を覆うカバー２３０に当たって勢いが弱められてから表皮部材１１０又は１２０に当るようになっている。このような構造とすることにより、カバー２３０に当たって勢いが弱められたウレタン発泡原液１５１は、表皮部材１１０又は１２０に浸み込むことがなくなり、ヘッドレスト２００の触感を損ねてしまうことを無くすことができる。 On the other hand, in this embodiment, the urethane foam stock solution 151 vigorously popping out from the nozzle 140 hits the cover 230 covering the tip portion of the nozzle 140 to weaken the momentum, and then hits the skin member 110 or 120. There is. With such a structure, the urethane foam stock solution 151, which has been weakened by hitting the cover 230, does not permeate into the skin member 110 or 120, and the tactile sensation of the headrest 200 can be prevented from being impaired. ..

ノズル１４０から袋状に形成された表皮１００の内部に供給されたウレタン発泡原液１５１は、表皮１００の内部で発泡して発泡ウレタン１５０が形成され、図５に示すように、袋状に形成された表皮１００を押し広げる。その結果、表皮部材１１０や１２０は、金型３１１と３１２で形成された形状に倣って成形される。 The urethane foam stock solution 151 supplied from the nozzle 140 to the inside of the epidermis 100 formed in a bag shape is foamed inside the epidermis 100 to form the urethane foam 150, and is formed in a bag shape as shown in FIG. Spread the epidermis 100. As a result, the skin members 110 and 120 are formed according to the shapes formed by the molds 311 and 312.

ここで、表皮部材１１０の側の切片１１１が発泡ウレタン１５０に接していない場合には、開口部２２０において、発泡ウレタン１５０から受ける圧力により切片１１１と１２１とが離れて隙間が形成されてしまう可能性がある。これは、表皮部材１１０と１２０とを、１層構造の比較的柔軟な部材で形成した場合により顕著になる。 Here, when the section 111 on the side of the skin member 110 is not in contact with the urethane foam 150, the sections 111 and 121 may be separated from each other by the pressure received from the urethane foam 150 at the opening 220 to form a gap. There is sex. This becomes more remarkable when the skin members 110 and 120 are formed of a relatively flexible member having a one-layer structure.

そのような隙間が形成されると、その隙間から発泡ウレタン１５０の一部が外部に漏れ出てしまう可能性がある。また、発泡ウレタン１５０が外部に漏れでなくとも、発泡ウレタン１５０で押し上げられることにより、切片１１１の表皮部材１１０から折り曲げた部分がめくれた状態になってしてしまう可能性がある。その結果、ヘッドレスト２００の外観を損ねてしまう場合が発生する。 When such a gap is formed, a part of the urethane foam 150 may leak to the outside through the gap. Further, even if the urethane foam 150 does not leak to the outside, there is a possibility that the bent portion of the section 111 from the skin member 110 may be turned up by being pushed up by the urethane foam 150. As a result, the appearance of the headrest 200 may be spoiled.

この課題に対して、本実施例では、表皮部材１２０の切片１２１で縫合部２１０よりも内側(図２で、開口部２２０の寸法Ｌよりも狭い間隔)に複数の穴１２２(図２に示した例では２個)を形成し、この穴１２２を通して表皮部材１１０の側の切片１１１も発泡ウレタン１５０に接するようにした。このように、切片１２１の複数の穴１２２を通して切片１１１の表面に発泡ウレタンを含浸させて切片１１１と発泡ウレタン１５０とを接着させることにより、発泡ウレタン１５０から受ける圧力により切片１１１と１２１とが離れて隙間が形成されてしまうのを防止した。 In response to this problem, in this embodiment, a plurality of holes 122 (shown in FIG. 2) in the section 121 of the epidermis member 120 inside the suture portion 210 (in FIG. 2, at intervals narrower than the dimension L of the opening 220). In the example, two) were formed, and the section 111 on the side of the skin member 110 was also brought into contact with the urethane foam 150 through the hole 122. In this way, by impregnating the surface of the section 111 with urethane foam through the plurality of holes 122 of the section 121 and adhering the section 111 and the urethane foam 150, the sections 111 and 121 are separated by the pressure received from the urethane foam 150. Prevented the formation of gaps.

この構成を、図６を用いて説明する。図６には、表皮部材１２０の切片１２１に形成された穴１２２を横切る断面Ｂ−Ｂ(図１参照)で、内部(図６において、表皮部材１１０及び１２０の下側)に発泡ウレタン１５０が充填された状態を示す。表皮部材１２０の切片１２１は、発泡ウレタン１５０に接している。更に、切片１２１の２箇所に形成した穴１２２を介して、表皮部材１１０の側の切片１１１にも発泡ウレタン１５０が接している。これにより、発泡ウレタン１５０が切片１１１に接着し、開口部２２０において、切片１１１と１２１とが密着した状態を保っている。 This configuration will be described with reference to FIG. FIG. 6 shows a cross section BB (see FIG. 1) crossing the hole 122 formed in the section 121 of the skin member 120, and urethane foam 150 is provided inside (lower side of the skin members 110 and 120 in FIG. 6). Indicates the filled state. The section 121 of the skin member 120 is in contact with the urethane foam 150. Further, the urethane foam 150 is also in contact with the section 111 on the side of the skin member 110 through the holes 122 formed at the two positions of the section 121. As a result, the urethane foam 150 adheres to the section 111, and the sections 111 and 121 are kept in close contact with each other at the opening 220.

また、この複数の穴１２２を、切片１１１を折り返した箇所に出来るだけ近付けた位置に設けることにより、切片１１１を表皮部材１１０から折り返した部分がめくれ上がるのをより抑えることが出来る。具体的には、複数の穴１２２を、切片１１１に形成したノズル１４０を通すための切り込み１４１よりも切片１１１を折り返した箇所に、より近い位置に形成する。これにより、切片１１１が折り返した箇所の近くで切片１１１を発泡ウレタン１５０と接着させることが出来、切片１１１を表皮部材１１０から折り返した部分がめくれ上がるのをより抑えることが出来る。 Further, by providing the plurality of holes 122 at positions as close as possible to the folded portion of the section 111, it is possible to further prevent the portion where the section 111 is folded back from the skin member 110 from being turned up. Specifically, the plurality of holes 122 are formed at positions closer to the folded-back portion of the section 111 than the notch 141 for passing the nozzle 140 formed in the section 111. As a result, the section 111 can be adhered to the urethane foam 150 near the portion where the section 111 is folded back, and the portion where the section 111 is folded back from the skin member 110 can be further suppressed from being turned up.

また、開口部２２０の幅寸法Ｌを従来の開口部の幅寸法と比べて小さくすることができるので、この小さくした開口部寸法と、この開口部の寸法Ｌよりも狭い間隔で２箇所に形成した穴１２２とを組み合わせることにより、特許文献２に記載されているような開口整形治具を用いなくても、開口部２２０において、切片１１１と１２１との密着した状態を確実に維持しながら表皮１００の内部で発泡ウレタン１５０を形成することが出来るようになった。 Further, since the width dimension L of the opening 220 can be made smaller than the width dimension of the conventional opening, the width dimension L of the opening 220 is formed at two locations at a narrower interval than the reduced opening dimension L. By combining with the hole 122, the epidermis is reliably maintained in close contact with the sections 111 and 121 in the opening 220 without using an opening shaping jig as described in Patent Document 2. It has become possible to form urethane foam 150 inside 100.

ここで、穴１２２の径(直径)は、穴１２２を介して、切片１１１を発泡ウレタン１５０と確実に接続させるために、３〜１０ｍｍ、より好ましくは、５〜８ｍｍに設定する。穴１２２の径を１０ｍｍよりも大きくすると、切片１１１と１２１との間から発泡ウレタン１５０が外部にはみ出して、ヘッドレスト２００の外観を損ねてしまう場合がある。また、穴１２２の径が３ｍｍよりも小さいと、切片１１１と発泡ウレタン１５０との接触面積が小さくなって、切片１１１と発泡ウレタン１５０との間で十分な接着力を確保することが出来なくなり、発泡ウレタン１５０から受ける圧力により切片１１１と１２１とが離れて隙間が形成され、発泡ウレタン１５０が外部に漏れ出てしまう場合がある。 Here, the diameter of the hole 122 is set to 3 to 10 mm, more preferably 5 to 8 mm in order to reliably connect the section 111 to the urethane foam 150 via the hole 122. If the diameter of the hole 122 is made larger than 10 mm, the urethane foam 150 may protrude from between the sections 111 and 121 and spoil the appearance of the headrest 200. Further, if the diameter of the hole 122 is smaller than 3 mm, the contact area between the section 111 and the urethane foam 150 becomes small, and it becomes impossible to secure a sufficient adhesive force between the section 111 and the urethane foam 150. Due to the pressure received from the urethane foam 150, the sections 111 and 121 may be separated from each other to form a gap, and the urethane foam 150 may leak to the outside.

このような状態で、開口部２２０において発泡ウレタン１５０から圧力を受けても、切片１２１の２箇所に形成した穴１２２を介して発泡ウレタン１５０と接続している切片１１１は、切片１２１と離れることなく密着した状態を保つことが出来る。その結果、開口部２２０から外部に発泡ウレタン１５０が漏れ出ることがなくなり、図７に示すように、外観を損ねることなくヘッドレスト２００を形成することが出来る。 In such a state, even if pressure is applied from the urethane foam 150 at the opening 220, the section 111 connected to the urethane foam 150 via the holes 122 formed at two positions of the section 121 is separated from the section 121. It is possible to maintain a close contact without any. As a result, the urethane foam 150 does not leak to the outside from the opening 220, and as shown in FIG. 7, the headrest 200 can be formed without impairing the appearance.

なお、図２には、切片１２１に径が３〜１０ｍｍの穴１２２を２箇所形成する例を示したが、本実施例はこれに限られるものではなく、穴１２２に代えて、スリット状の長穴を複数形成するようにしても良い。 Note that FIG. 2 shows an example in which two holes 122 having a diameter of 3 to 10 mm are formed in the section 121, but this embodiment is not limited to this, and instead of the holes 122, a slit shape is formed. A plurality of elongated holes may be formed.

本実施例によれば、ヘッドレスト２００の表皮１００を１層の表皮部材１１０，１２０で形成しても、袋状に成形した表皮１００の内部にウレタン発泡原液１５１を供給して表皮１００の内部に発泡ウレタン１５０を充填させる場合において、表皮１００に形成した開口部２２０から発泡ウレタン１５０が外部に漏れ出てしまうのを確実に防止することが出来るようにした。これにより、１層の表皮部材１１０，１２０で形成した表皮１００を用いたヘッドレスト２００を、外観の見栄えや肌触りの感触を損なうことなく、確実に形成することが出来るようになった。 According to this embodiment, even if the skin 100 of the headrest 200 is formed by the skin members 110 and 120 of one layer, the urethane foam stock solution 151 is supplied to the inside of the skin 100 formed into a bag shape to the inside of the skin 100. When the urethane foam 150 is filled, it is possible to reliably prevent the urethane foam 150 from leaking to the outside through the opening 220 formed in the skin 100. As a result, the headrest 200 using the skin 100 formed of the one-layer skin members 110 and 120 can be reliably formed without impairing the appearance and the feel of the skin.

なお、本実施例では、表皮１００を１層で形成した場合について説明したが、表皮１００の発泡ウレタン１５０と接する側の面(袋状に形成した表皮１００の内側の面)に、５０μｍ以下、より好ましくは２０〜３０μｍ又はそれ以下の厚さを有する薄い樹脂の層１００１を形成しても良い。 In this embodiment, the case where the epidermis 100 is formed by one layer has been described, but the surface of the epidermis 100 on the side in contact with the urethane foam 150 (the inner surface of the epidermis 100 formed in a bag shape) is 50 μm or less. More preferably, a thin resin layer 1001 having a thickness of 20 to 30 μm or less may be formed.

このように薄い樹脂の層１０１１を形成することにより、本実施例で説明した表皮１００を１層で形成した場合とほぼ変わりのない柔軟性を確保した上で、発泡ウレタン１５０が表皮１００に染込むことを確実に防止でき、ヘッドレスト２００の外観の見栄えを損なってしまうこと、及び肌触りの感触を損なってしまうことを防ぐことが出来る。 By forming the thin resin layer 1011 in this way, the urethane foam 150 dyes the skin 100 while ensuring flexibility that is almost the same as when the skin 100 described in this embodiment is formed by one layer. It is possible to surely prevent it from getting stuck, and it is possible to prevent the appearance of the headrest 200 from being impaired and the feel of the headrest 200 from being impaired.

また、この薄い樹脂の膜の表面をコロナ放電で処理して膜の表面に改質処理を施すことにより、膜の表面に微細な凹凸を形成して、発泡ウレタン１５０との接着性を向上させることが出来る。その結果、切片１２１と発泡ウレタン１５０とがより強く接着され、折り返し部のめくれ上がりをより少なくすることが出来る。 Further, by treating the surface of this thin resin film with corona discharge and modifying the surface of the film, fine irregularities are formed on the surface of the film to improve the adhesiveness with the urethane foam 150. Can be done. As a result, the section 121 and the urethane foam 150 are more strongly adhered to each other, and it is possible to reduce the turning up of the folded portion.
