Description

【０００１】
【発明の属する技術分野】
本発明は二輪車用表皮吊り込みシートに関する。
【０００２】
【従来の技術】
従来から二輪車用シートは、例えば図５で示すようなシートＳは、ボトムプレート上にクッション材を配置して表皮で被覆して形成されている。そして二人乗りシートは前席Ｓｆと後席Ｓｒとを有しており、シートのデザイン等の外観意匠性を考慮して、凹凸形状シートとしたり、前席Ｓｆ及び後席Ｓｒの座面部の表皮１１０と、それ以外の部分の表皮１２０とで、表皮の材質や彩色等を異なるように構成したり、表皮の吊り込みをしたりして商品性の向上を図っている。
【０００３】
つまり図５で示すようなシートＳにおいては、図６で示すように、クッション材１２２に凹部ライン１２２ａを形成し、さらに表皮の接合部の吊り込み部分（図５の破線で示す）にターポリン１３０を取り付け、このターポリン１３０を介して吊り込み具（吊り込み紐）１３１でボトムプレート側へ吊り込んでいた。また吊り込み以外の部分では、図７で示すように、凹部ライン１２２ａに表皮材の接合部分が配置される。
【０００４】
【発明が解決しようとする課題】
そして凹凸形状を有した表皮吊り込みシートＳでは、凹部ライン１２２ａが複雑な曲線（Ｓ字曲線等を描く場合）や３次元曲線を描く場合は、図５で示すように、吊り込み個所を曲線の曲げポイント毎に多くの吊り込みポイントを設定しなければ、凸凹形状のメリハリ感が出にくいという問題があった。
【０００５】
しかし吊り込みポイントが増加すると局部的（吊り込んだポイントのみ）に「エクボ」のような状態が外観面に現われて外観に支障をきたすと共に、組み付け作業性の効率も悪化するという不都合があった。このため局部的な「エクボ」状の現出を抑えるとともに凹凸形状のめりはり感を保持し、且つ吊り込みポイントの数的減少化が課題となっている。
【０００６】
また上記のように凹凸形状を有した表皮吊り込みシートＳでは、凹凸形状シートに合わせて表皮を接合する必要があり、この表皮接合ライン形状が複雑になるために、表皮を予備成形したり、複数の表皮を縫合や接合する必要があった。
【０００７】
つまり図８で示すように、面Ｘ，Ｙ，Ｚの三面以上がぶつかり合う頂点の角Ｒ部１２５は、従来予備成形をしないで、一枚の表皮で被せたり、単に二枚の表皮を平面的に接合した表皮で被せると、表皮が余ってだぶつき、クッション材の形状に合わせた被覆が不可能であった。
【０００８】
このため、表皮を三面で形成し、この三面でつくられるいずれか１つの稜線（ハイライト線）の部分を切り込み、角Ｒ部の形状に合わせて切除した後で、図８で示すように、縫合ラインＨで縫合して、角Ｒ形状に合わせて接合するという手段を採用しなければならなかった。
【０００９】
本発明の目的は、シート側面への表皮密着性が向上し凸凹のメリハリ感を出すことができる二輪車用表皮吊り込みシートを提供することにある。本発明の他の目的は、複雑な曲線形状の稜線（ハイライト線）における表皮の接合部をなくして、外観商品性の向上とコストの削減が可能な二輪車用表皮吊り込みシートを提供することにある。
【００１０】
【課題を解決するための手段】
本発明に係る二輪車用表皮吊り込みシートは、ボトムプレート上にクッション材を配置して表皮で被覆してなる二人乗り用の二輪車用シートであって、前記表皮は前席及び後席の座面部に配置される第１表皮材と、座面部以外に配置される第２表皮材とを接合して形成され、前記後席の座面部の後方側は前記後席に配置された第１表皮材で端末まで被覆されると共にボトムプレート裏面で端末処理され、前記後席に配置された第１表皮材と第２表皮材との接合部のうちシート中央から側面への接合部は、蛇行した曲線形状となっており、前記後席に配置された第１表皮材と第２表皮材との接合部には、端末の手前位置までターポリンを配設し、前記クッション材の表面側には前記後席に配置された第１表皮材と第２表皮材の接合ラインに合わせた凹部ラインを形成し、少なくとも前記後席の座面部の凹部ラインに沿って前記ターポリンが配設された接合部を配置し、前記接合部のうちシート中央の範囲内のターポリンを介して接合部を吊り込み具によって、吊り込んでなることを特徴とする。
【００１１】
前記蛇行した曲線形状となった前記後席に配置された第１表皮材と第２表皮材との接合部近傍が前記クッション材の角Ｒ部となっており、前記後席に配置された第１表皮材と前記第２表皮材の接合部における曲線形状部分を、クッション材の角Ｒ部形状に合わせて接合する際に、前記クッション材の各角Ｒ部を被覆する部分に相当する前記後席に配置された第１表皮材と第２表皮材の外周側又は内周側の各周長を変えて、前記後席に配置された第１表皮材と第２表皮材を接合してクッション材の角Ｒ部を被覆して形成すると好適である。
【００１２】
本発明に係る二輪車用表皮吊り込みシートは、ボトムプレート上にクッション材を配置して表皮で被覆してなる一人乗り用の二輪車用シートであって、前記表皮は座面部に配置される第１表皮材と、座面部以外に配置される第２表皮材と、前記座面部の後方側に配置される第３表皮材とを接合して形成され、前記座面部の後方側は前記第３表皮材で端末まで被覆されると共にボトムプレート裏面で端末処理され、前記座面部の後方側の第３表皮材と第２表皮材との接合部のうちシート中央から側面への接合部は、蛇行した曲線形状となっており、前記座面部の後方側の第３表皮材と第２表皮材との接合部には、端末の手前位置までターポリンを配設し、前記クッション材の表面側には前記第３表皮材と第２表皮材の接合ラインに合わせた凹部ラインを形成し、少なくとも前記座面部の後方側の凹部ラインに沿って前記ターポリンが配設された接合部を配置し、前記接合部のうちシート中央の範囲内のターポリンを介して接合部を吊り込み具によって、吊り込んでなることを特徴とする。
【００１３】
前記蛇行した曲線形状となった座面部の後方側の第３表皮材と第２表皮材との接合部近傍が前記クッション材の角Ｒ部となっており、前記第３表皮材と前記第２表皮材の接合部における曲線形状部分を、クッション材の角Ｒ部形状に合わせて接合する際に、前記クッション材の各角Ｒ部を被覆する部分に相当する前記第３表皮材と第２表皮材の外周側又は内周側の各周長を変えて、前記第３表皮材と第２表皮材を接合してクッション材の角Ｒ部を被覆して形成すると好適である。
【００１４】
さらに第２表皮材は伸縮性の良いレザーから構成すると好適である。
【００１５】
【発明の実施の形態】
本例に係る二輪車用シートＳを、前席Ｓｆと後席Ｓｒを有する二人乗り用のシートで説明する。本例の二輪車用シートは、ボトムプレート１上にクッション材２を配置して表皮３で被覆して形成されている。
【００１６】
本例のボトムプレート１は一枚ものの合成樹脂材で構成されており、前席Ｓｆと後席Ｓｒを一体で支えるものである。そして前席Ｓｆより後席Ｓｒ側が高い位置となるように、前席Ｓｆと後席Ｓｒとの間に段差部４を有して形成されている。
【００１７】
クッション材２は上記ボトムプレート１の上に載置されるものであり、ボトムプレート１の形状に合わせて、段差部４を介して、前席Ｓｆ側が低く、後席Ｓｒ側が高くなるように形成されている。
【００１８】
さらにクッション材２の表面には、図４の一点鎖線で示すように、後席の座面部を被覆する第１表皮材１０と座面部以外を被覆する第２表皮材２０との接合部に相当する部分に凹部ライン２ａを形成している。
【００１９】
表皮３は、前席及び後席の座面部を被覆する第１表皮材１０と座面部以外を被覆する第２表皮材２０とから構成されており、第１表皮材１０は前席Ｓｆと後席Ｓｒの各座面部に配置され、第２表皮材２０は前席Ｓｆと後席Ｓｒの各座面部以外に配置されるものである。
【００２０】そして後席Ｓｒを被覆する第１表皮材１０は、後席Ｓｒの側面から端末まで被覆して、ボトムプレート１の裏面で図示しないタッカー等により端末処理されている。
【００２１】
また後席Ｓｒ側の第１表皮材１０は、図１で示すように、凸状部１１が形成されて、前席Ｓｆと後席Ｓｒとを連結する連結部側である段差部４へ突出して形成されている。そして第１表皮材１０と第２表皮材２０との接合部のうち中央から側面側へ連なる接合部は、角Ｒ部に向けて蛇行した曲線形状となっている。
【００２２】
上記蛇行した曲線形状となった後席Ｓｒ側の第１表皮材１０と第２表皮材２０との接合部のうち、後席Ｓｒの座面側との接合部近傍がクッション材２の角Ｒ部５となっている。そして、第１表皮材１０と前記第２表皮材２０は、クッション材２の各角Ｒ部５を被覆する部分に相当する外周側又は内周側の各周長を変えて、第１表皮材１０と第２表皮材２０を接合している。
【００２３】
そして第２表皮材２０は伸縮性の良いレザーを使用している。このため、クッション材２の角Ｒ部５を表皮３で被覆したときに、表皮３の被覆量が不足するが、第２表皮材２０が伸長して、不足量をカバーする。
【００２４】
また後席Ｓｒ側の第１表皮材１０と第２表皮材２０との接合部には、ターポリン３０が配設されており、このターポリン３０は、図１で示すように、端末の手前位置まで配設されている。このターポリン３０の所定位置には吊り込み具としての吊り込みループ３１が配置されている。
【００２５】
吊り込みループ３１の配置位置は、図１で示すように、後席Ｓｒ側の第１表皮材１０における凸状部１１の中心位置と、凸状部１１の両方の角部の合計３カ所に形成している。この吊り込みループ３１の形成位置は、前記したクッション材２の吊り込み用の穴２ｂと一致するように取り付けられている。
【００２６】
そして組み付けは、先ずクッション材２の表面側に形成された凹部ライン２ａに前記第１表皮材１０と第２表皮材２０の接合ラインを合わせて配置する。次にクッション材２に形成された吊り込み用の穴２ｂを介して吊り込みループ３１によりボトムプレート１側へ、第１表皮材１０及び第２表皮材２０の接合部（ターポリン３０）を吊り込む。
【００２７】
以上のように構成されているので、吊り込み部分が、第１表皮材１０の凸状部１１の中心位置と凸状部１１の角部の３カ所だけでの吊り込みにも拘わらず、凹部ライン２ａが露見し、シャープな形状出しが可能となる。
【００２８】
また同時に、ボトムプレート１の端末まで凹部ライン２ａが延長されているので、表皮３の凹部ライン２ａがシート端末処理により側面へ密着して、形状出しが側面まで可能となり、シートＳの側面への表皮３の密着性が向上し、凹凸メリハリ感を出すことができる。
【００２９】
さらに第１表皮材１０と前記第２表皮材２０は、クッション材２の各角Ｒ部５を被覆する部分に相当する外周側又は内周側の各周長を変えて、第１表皮材１０と第２表皮材２０を接合しており、第２表皮材２０は伸縮性の良いレザーを使用している。このため、クッション材２の角Ｒ部５を表皮３で被覆したときに、表皮３の被覆量が不足するが、第２表皮材２０が伸長して、不足量をカバーする。そして複雑な曲線形状の稜線（ハイライト線）における表皮の接合部をなくして、外観商品性の向上とコストの削減が可能となる。
【００３０】
【実施例】
以下、本発明の一実施例を図面に基づいて説明する。なお、以下に説明する部材，配置等は本発明を限定するものでなく、本発明の趣旨の範囲内で種々改変することができるものである。
【００３１】
本実施例では、二輪車用シートとして二人乗り用シートを例にして説明するが、本発明は一人乗り用シートであっても良いことは勿論である。そして図１乃至図４は本発明に係る実施例を示すものであり、図１は二輪車用シートの説明斜視図、図２は図１のＡ−Ａ断面図、図３は図１のＢ−Ｂ断面図、図４は図１の要部拡大説明図である。
【００３２】
本例に係る二輪車用シートＳは、前席Ｓｆと後席Ｓｒを有する二人乗り用のシートであり、ボトムプレート１上にクッション材２を配置して表皮３で被覆して形成されている。
【００３３】
本例のボトムプレート１は一枚ものの合成樹脂材で構成されており、前席Ｓｆと後席Ｓｒを一体で支えるものである。そして前席Ｓｆより後席Ｓｒ側が高い位置となるように、前席Ｓｆと後席Ｓｒとの間に段差部４を有して形成されている。上記ボトムプレート１の材質は合成樹脂に限定されるものではなく、金属製のものも用いることもできる。また前席Ｓｆと後席Ｓｒとを支えるのに分割されたボトムプレートを用いることもできる。
【００３４】
本例のクッション材２は上記ボトムプレート１の上に載置されるものであり、ボトムプレート１の形状に合わせて前席Ｓｆ側が低く、後席Ｓｒ側が高くなるように形成されている。そして本例のクッション材２は、前席Ｓｆと後席Ｓｒとの間の段差部４に合わせて形成されており、後席Ｓｒ側の段差部４の上部の両側は角Ｒ部５として形成された複雑な曲線形状となって形成されている。
【００３５】
さらにクッション材２の表面には、図４の一点鎖線で示すように、後述する座面部を被覆する第１表皮材１０と、座面部以外を被覆する第２表皮材２０との接合部に相当する部分に凹部ライン２ａを形成している。つまり表皮３でクッション材２を被覆したときの第１表皮材１０と第２表皮材２０との接合部に相当する位置に凹部ライン２ａを形成する。本例におけるクッション材２に形成された凹部ライン２ａは、ボトムプレート１の端末まで達している。そして本例では、前席Ｓｆと後席Ｓｒとの間の前席Ｓｆ側寄りの部分に吊り込み用の穴２ｂが３カ所形成されている。
【００３６】
なお上記ボトムプレート１が前席Ｓｆと後席Ｓｒの高さがあまり違わなくても、前席Ｓｆと後席Ｓｒのクッション材２の高さを違えるように構成することにより、前席Ｓｆと後席Ｓｒの段差部４や角Ｒ部５等を形成することができる。
【００３７】
本例の表皮３は、第１表皮材１０と第２表皮材２０とから構成されており、第１表皮材１０は前席Ｓｆと後席Ｓｒの各座面部に配置され、第２表皮材２０は、前席Ｓｆと後席Ｓｒの各座面部以外に配置されるものである。これら第１表皮材１０と第２表皮材２０は、材質や彩色が異なるもので、本例では防水の観点や熱熱溶着等を考慮して、ＰＶＣや人工レザー等から構成されており、接合は例えば高周波ウエルダ加工、超音波溶着等により行われる。なお、一人乗り用シートの場合には、上記後席側の第１表皮材１０は、座面部が形成されないため、ライダーの座面部の後方を被せる第３表皮材として構成される。
【００３８】
後席Ｓｒを被覆する第１表皮材１０は、後席Ｓｒの側面から端末まで被覆して、ボトムプレート１の裏面で図示しないタッカー等により端末処理されている。従って、座面部までをカバーする第１表皮材１０がシート側面での密着性を充分確保する。
【００３９】
また後席Ｓｒ側の第１表皮材１０は、図１で示すように、凸状部１１が形成されて、前席Ｓｆと後席Ｓｒとを連結する連結部側である段差部４へ突出して形成されている。そして第１表皮材１０と第２表皮材２０との接合部のうち中央から側面側へ連なる接合部は、角Ｒ部に向けて蛇行した曲線形状（本例ではＳ字形状）となっている。
【００４０】
本例では上記蛇行した曲線形状となった後席Ｓｒ側の第１表皮材１０と第２表皮材２０との接合部のうち、後席Ｓｒの座面側との接合部近傍がクッション材２の角Ｒ部５となっている。そして、第１表皮材１０と前記第２表皮材２０の接合における曲線形状の部分を、クッション材２の角Ｒ部５の形状に合わせて接合する際に、第１表皮材１０と第２表皮材２０のクッション材２の各角Ｒ部５を被覆する部分に相当する外周側又は内周側の各周長を変えて、第１表皮材１０と第２表皮材２０を接合している。つまり本例では、第２表皮材２０の周長を、円弧形状を大きくすることで、第１表皮材１０の周長より少なくしている。
【００４１】
本例の第２表皮材２０は伸縮性の良いレザーを使用している。本例では０．８ｍｍの厚さのＰＶＣソフトレザーを使用している。このため、クッション材２の角Ｒ部５を表皮３で被覆したときに、表皮３の被覆量が不足するが、第２表皮材２０が伸長して、不足量をカバーする。従って、図４で示すように、クッション材２の角Ｒ部５の頂点は表皮３により潰されるが、従来のような余分な余った表皮３の部分を切除して稜線（ハイライト線）の接合部により合わせて形成することをせずに、複雑な曲線形状のクッション材２を表皮３で被覆することができるために、外観商品性の向上が図れると共に、接合工程を少なくすることができ、コストの低減を図ることが可能となった。なお表皮材２０の材質はＰＶＣに限定されることなく耐候性を備えた伸縮性の良いものを使用できる。
【００４２】
また後席Ｓｒ側の第１表皮材１０と第２表皮材２０との接合部には、ターポリン３０が配設されており、このターポリン３０は、図１で示すように、端末の手前位置まで配設されている。このターポリン３０は第１表皮材１０と第２表皮材２０を溶着するときに、同時に溶着するものであり、所定位置には吊り込み具としての吊り込みループ３１が配置されている。
【００４３】
本例の吊り込みループ３１の配置位置は、図１で示すように、後席Ｓｒ側の第１表皮材１０における凸状部１１の中心位置と、凸状部１１の両方の角部の合計３カ所に形成している。この吊り込みループ３１の形成位置は、前記したクッション材２の吊り込み用の穴２ｂと一致するように取り付けられている。
【００４４】
なお吊り込みループ３１は、ターポリン３０に予め配設しておいてもよく、あるいはターポリン３０の部分に後付して形成してもよい。いずれの場合でもターポリン３０の部分だけに吊り込みループ３１の配設用の穴（図示せず）を形成し、吊り込みループ３１を配設するものである。
【００４５】
次に上記構成からなる組み付けについて説明する。クッション材２の表面側に形成された凹部ライン２ａに前記第１表皮材１０と第２表皮材２０の接合ラインを合わせて配置する。そしてクッション材２に形成された吊り込み用の穴２ｂを介して吊り込みループ３１によりボトムプレート１側へ、第１表皮材１０及び第２表皮材２０の接合部（ターポリン３０）を吊り込む。
【００４６】
このとき少なくとも後席Ｓｒ側の接合ラインにはターポリン３０が形成されており、第１表皮材１０と第２表皮材２０の接合部とターポリン３０が、上記凹部ライン２ａ内に位置するために、吊り込み部分が、第１表皮材１０の凸状部１１の中心位置と凸状部１１の角部の３カ所だけでの吊り込みにも拘わらず、凹部ライン２ａが露見し、シャープな形状出しが可能となる。
【００４７】
また同時に、ボトムプレート１の端末まで凹部ライン２ａが延長されているので、表皮３の凹部ライン２ａがシート端末処理により側面へ密着して、形状出しが側面まで可能となり、シートＳの側面への表皮３の密着性が向上し、凹凸メリハリ感を出すことができる。
【００４８】
なお吊り込みループ３１による吊り込みは、図示しないが、ボトムプレート１に係止部を形成し、この係止部と係合するホック等により、ボトムプレート１側へ引き込んで行う。また係止部はボトムプレート１に穴を形成し、吊り込みループ３１を係止部材に係合させて、上記穴に係止部材を係合するように構成することもできる。
【００４９】
なお、本発明は次の態様を含むものである。ボトムプレート上にクッション材を配置して表皮で被覆してなる二人乗り用の二輪車用シートであって、前記表皮は前席及び後席の座面部に配置される第１表皮材と、前記座面部以外に配置される第２表皮材とを接合して形成され、前記後席の座面部の後方側は前記後席に配置された第１表皮材で端末まで被覆されると共にボトムプレート裏面で端末処理され、前記後席に配置された第１表皮材と第２表皮材との接合部のうちシート中央から側面への接合部は、蛇行した曲線形状となっており、前記後席に配置された第１表皮材と第２表皮材との接合部には、端末の手前位置までターポリンを配設し、前記クッション材の表面側には前記後席に配置された第１表皮材と第２表皮材の接合ラインに合わせた凹部ラインを形成し、少なくとも前記後席の座面部の凹部ラインに沿って前記ターポリンが配設された接合部を配置し、前記接合部のうちシート中央の範囲内のターポリンを介して接合部を吊り込み具によって、吊り込んでなることを特徴とする二輪車用表皮吊り込みシート。
【００５０】
前記蛇行した曲線形状となった前記後席に配置された第１表皮材と第２表皮材との接合部近傍が前記クッション材の角Ｒ部となっており、前記後席に配置された第１表皮材と前記第２表皮材の接合部における曲線形状部分を、クッション材の角Ｒ部形状に合わせて接合する際に、前記クッション材の各角Ｒ部を被覆する部分に相当する前記後席に配置された第１表皮材と第２表皮材の外周側又は内周側の各周長を変えて、前記後席に配置された第１表皮材と第２表皮材を接合してクッション材の角Ｒ部を被覆したことを特徴とする請求項１記載の二輪車用表皮吊り込みシート。
【００５１】
ボトムプレート上にクッション材を配置して表皮で被覆してなる一人乗り用の二輪車用シートであって、前記表皮は座面部に配置される第１表皮材と、座面部以外に配置される第２表皮材と、前記座面部の後方側に配置される第３表皮材とを接合して形成され、前記座面部の後方側は前記第３表皮材で端末まで被覆されると共にボトムプレート裏面で端末処理され、前記座面部の後方側の第３表皮材と第２表皮材との接合部のうちシート中央から側面への接合部は、蛇行した曲線形状となっており、前記座面部の後方側の第３表皮材と第２表皮材との接合部には、端末の手前位置までターポリンを配設し、前記クッション材の表面側には前記第３表皮材と第２表皮材の接合ラインに合わせた凹部ラインを形成し、少なくとも前記座面部の後方側の凹部ラインに沿って前記ターポリンが配設された接合部を配置し、前記接合部のうちシート中央の範囲内のターポリンを介して接合部を吊り込み具によって、吊り込んでなることを特徴とする二輪車用表皮吊り込みシート。
【００５２】
前記蛇行した曲線形状となった座面部の後方側の第３表皮材と第２表皮材との接合部近傍が前記クッション材の角Ｒ部となっており、前記第３表皮材と前記第２表皮材の接合部における曲線形状部分を、クッション材の角Ｒ部形状に合わせて接合する際に、前記クッション材の各角Ｒ部を被覆する部分に相当する前記第３表皮材と第２表皮材の外周側又は内周側の各周長を変えて、前記第３表皮材と第２表皮材を接合してクッション材の角Ｒ部を被覆したことを特徴とする請求項３記載の二輪車用表皮吊り込みシート。
【００５３】上記態様において、前記第２表皮材は伸縮性の良いレザーから構成されていることを特徴とする二輪車用表皮吊り込みシート。
【００５４】
【発明の効果】
以上のように本発明によれば、吊り込み部分が、第１表皮材の凸状部の中心位置と、凸状部の両角部の３カ所だけでの吊り込みにも拘わらず、凹部ラインが露見し、シャープな形状出しが可能となる。
【００５５】
また同時に、ボトムプレート端末まで凹部ラインが延長されているので、表皮の凹部ラインがシート端末処理により側面へ密着して、形状出しが側面まで可能となり、シートの側面への表皮の密着性が向上し、凹凸メリハリ感を出すことができる。特に座面部の後方側を被覆する第３表皮材が、座面部の後方側の側面から端末まで被覆して、ボトムプレート裏面で端末処理されているのと相俟って、シート側面の密着性と凹部ラインと吊り込みとで、より一層の凹凸メリハリ感を確保することができる。
【００５６】
さらに第３表皮材と前記第２表皮材は、クッション材の各角Ｒ部を被覆する部分に相当する外周側又は内周側の各周長を変えて、第３表皮材と第２表皮材を接合しており、第２表皮材は伸縮性の良いレザーを使用している。このため、クッション材の角Ｒ部を表皮で被覆したときに、表皮の被覆量が不足するが、第２表皮材が伸長して、不足量をカバーする。そして複雑な曲線形状における稜線（ハイライト線）における表皮の接合部をなくして、外観商品性の向上とコストの削減が可能となる。
【００５７】
以上のように、本発明では、シート側面への表皮密着性が向上し凸凹のメリハリ感を出すことができる二輪車用表皮吊り込みシートとなり、更に外観商品性の向上が図れると共に、接合工程を少なくすることができ、コストの低減を図ることが可能となった。

Moreover, in the skin suspending sheet S having the uneven shape as described above, it is necessary to join the skin according to the uneven shape sheet, and since this skin joining line shape becomes complicated, the skin is preformed, It was necessary to sew or join multiple epidermis.
[0007]
That is, as shown in FIG. 8, the corner R portion 125 at the apex where three or more of the surfaces X, Y, and Z collide is covered with a single skin or is simply flat with two skins without performing preforming. When the cover was covered with a jointed skin, the skin would be excessively rough and could not be coated in accordance with the shape of the cushion material.
[0008]
For this reason, the epidermis is formed on three sides, and after cutting the portion of any one ridgeline (highlight line) made on these three sides and cutting it according to the shape of the corner R part, as shown in FIG. It was necessary to adopt a means of stitching at the stitching line H and joining in accordance with the corner R shape.
[0009]
An object of the present invention is to provide a skin suspending sheet for a motorcycle that can improve the adhesion of the skin to the side surface of the seat and can provide an uneven feeling. Another object of the present invention is to provide a skin suspending sheet for two-wheeled vehicles that can improve the appearance merchantability and reduce the cost by eliminating the joint portion of the skin on the ridgeline (highlight line) having a complicated curved shape. It is in.
