<全体構成>
図1は、本発明の第一実施形態に係る座席用表皮材の積層構造を模式的に示す断面図である。図1に示されるように、第一実施形態に係る座席用表皮材11は、表面層12と、裏面層13と、裏布14とを有し、表面層12の側から裏面層13の側に向けて貫通孔15(本発明の「孔部」に相当する。)が形成されている。なお、裏布14は、設けることが好ましい構成であるが、省略することも可能である。
表面層12としては、例えば、織物、編物、不織布等の布帛類、人工皮革、合成皮革、天然皮革等の皮革類等を用いることができる。
裏面層13を構成する材料としては、表面層12と同等のものを使用することができる。また、裏面層13は、例えば、クッション材で構成されることが好ましい。裏面層13をクッション材で構成することにより、着座感、及び触感が向上する。
裏面層13の下面には、貫通孔15の形成時の裏面層13(クッション材)の破損防止等の観点から、裏布14を設けることが好ましい。裏布14としては、特に限定されるものではなく、例えば、ポリエステル等の合成繊維からなる布帛が挙げられる。また、貫通孔15を形成する際の積層シートの打抜片を効率的に除去できるという観点から、低融点の繊維を用いた布帛を用いることが好ましい。なお、裏面層13の上面と下面とについて、表面層12と接触する側の面が上面であり、表面層12と接触する側の面の反対側の面が下面である。
貫通孔15は、表面層12の側から裏面層13の側に向けて縮径し、深さによって孔径が異なるように構成されている。このような貫通孔15は、深みのあるデザインとなり、意匠性が向上する。
次に、起毛又はバフ処理が施されたポリエステル織物によって表面層12が形成され、ポリウレタンフォームシートによって裏面層13が形成され、ポリエステル編物によって裏布14が形成される座席用表皮材11をエンボス加工法(平板エンボス加工法)によって製造する方法について説明する。なお、この製造方法の説明において例示する、表面層12、裏面層13、及び裏布14のそれぞれの構成材については、一例を挙げたにすぎず、ここで挙げた構成材に限定されるものではない。また、裏布14は省略される場合がある。
まず、図2(a)に示されるように、第一ドラム91から、表面層12を構成するポリエステル織物シートを繰り出し、第二ドラム92から、裏面層13を構成するポリウレタンフォームシートを繰り出し、ポリウレタンフォームシートの表面を加熱手段(本例ではバーナー93を例示する)で加熱し、ポリウレタンフォームシートの表面が溶融したところにポリエステル織物シートを貼り合わせるように一対のピンチロール94,95で挟みながら下流側へと送り、ポリエステル織物シートとポリウレタンフォームシートとが重ね合わされて溶着された二層シート(積層シート)を巻取りロール96で巻き取る。二層シートを巻き取った巻取りロール96は、第二ドラム92としてセットする。第一ドラム91に裏布14を構成するポリエステル編物シートをセットした後、これを繰り出しながら、第二ドラム92から、二層シートを繰り出し、二層シートにおけるポリウレタンフォームシートの表面を加熱手段で加熱し、ポリウレタンフォームシートの表面が溶融したところにポリエステル編物シートを貼り合わせるように一対のピンチロール94,95で挟みながら下流側へと送り、ポリエステル織物シート、ポリウレタンフォームシート、及びポリエステル編物シートが重ね合わされて溶着された三層シートを座席用表皮材の基材70として巻取りロール96で巻き取る。
次いで、図2(b)に示されるように、上記の基材形成工程にて形成された基材70を、貫通孔15を形成するための型押部17が基板18に立設されて構成される押し板80と、当該押し板80と対向する受け板81との間に挟み込む。このとき、基材70と受け板81との間に保護シート82が介挿されるように、受け板81上に保護シート82を予め載置しておくことが好ましい。
次いで、図2(c)に示されるように、表面層12を構成するポリエステル織物シートが溶融しない温度で受け板81を図示されない電熱線で加熱しながら、押し板80を受け板81に近づけるように相対移動させ、押し板80の型押部17を受け板81に押圧して基材70に貫通孔15を形成する。なお、裏面層13を構成するポリウレタンフォームシートは、表面層12を構成するポリエステル織物シートよりも熱によって軟化し易い。このため、座席用表皮材11においては、図1及び図2(d)に示されるように、裏面層13と共に裏布14が表面層12側に引き上げられて、当該座席用表皮材11の裏面は上凸円弧状に湾曲する(後述する図3~図8に示される第二実施形態乃至第七実施形態についても同様)。
次いで、図2(d)に示されるように、受け板81から押し板80を引き離すように押し板80を相対移動させ、貫通孔15が形成された基材70を、押し板80と受け板81との間から取り出す。こうして、貫通孔15を有する座席用表皮材11を製造することができる。
図3は、本発明の第二実施形態に係る座席用表皮材の積層構造を模式的に示す断面図である。第二実施形態において、第一実施形態と同一又は同様のものについては図に同一符号を付すに留めてその詳細な説明を省略することとし、以下においては、第二実施形態に特有の部分を中心に説明することとする(後述する第三実施形態乃至第七実施形態についても同様)。

図5は、本発明の第四実施形態に係る座席用表皮材の積層構造を模式的に示す断面図である。図5に示される第四実施形態に係る座席用表皮材41において、陥没孔45の内壁は、表面層12の側から裏面層13の側に向かう途中に形成される円環状の段面46を有し、段面46を境にして孔径が大きく変化するように構成されている。なお、座席用表皮材41において、陥没孔45を形成する場合、裏布14は溶融しない。このため、陥没孔45の底部下方における表面層12と裏面層13とは、表面層12及び/又は裏面層13(本例では表面層12及び裏面層13の両方)に含まれる成分の融着物116によって接合されている。
図6は、本発明の第五実施形態に係る座席用表皮材の積層構造を模式的に示す断面図で、(a)は孔部が貫通孔である場合、(b)は孔部が段付き貫通孔である場合、(c)は孔部が陥没孔である場合、(d)は孔部が段付き陥没孔である場合である。図6(a)~(d)に示されるように、第五実施形態に係る座席用表皮材51A~51Dは、表面層(表面組織)112に編み込まれた図示されない接結糸と、裏面層(裏面組織)113に編み込まれた図示されない接結糸とが互いに交絡することにより、表面層112と裏面層113とが接結されてなるダブルラッセル経編地を用いたものである。これら座席用表皮材51A~51Dにおいては、表面層112の側から裏面層113の側に向けて貫通孔55A(図6(a)参照)、及び段付き貫通孔55B(図6(b)参照)、並びに陥没孔55C(図6(c)参照)、及び段付き陥没孔55D(図6(d)参照)が形成されている。なお、座席用表皮材51A,51Bにおいて、裏面層113における貫通孔55A,55Bの開口周縁部は、表面層112、裏面層113、及び接結糸の1種以上(本例では3種全て)に含まれる成分の融着物216によって接合されている。また、座席用表皮材51C,51Dにおいて、陥没孔55C,55Dの底部下方における表面層112と裏面層113とは、表面層112、裏面層113、及び接結糸の1種以上(本例では接結糸)に含まれる成分の融着物316によって接合されている。
図7は、本発明の座席用表皮材の第六実施形態の説明図である。図7(a)~(d)に示される座席用表皮材61A,61B,61C,61Dは、第一実施形態乃至第四実施形態の座席用表皮材11,21,31,41において、表面層12と裏面層13との間に中間層200を設けるようにしたものである。こうして、中間層200を設けることにより、重厚感を持たせることができる。中間層200としては、例えば、織物、編物、不織布等の布帛類等や、ポリウレタンフォーム等の合成樹脂発泡体を用いることができる。なお、座席用表皮材61A,61Bにおいて、裏面層13における貫通孔15,25の開口周縁部は、表面層12、中間層200、裏面層13、及び裏布14の1種以上(本例では4種全て)に含まれる成分の融着物416によって接合されている。また、座席用表皮材61C,61Dにおいて、陥没孔35,45を形成する場合、裏布14は溶融しない。このため、陥没孔35,45の底部下方における表面層12と中間層200と裏面層13とは、表面層12、中間層200、及び裏面層13の1種以上(本例では3種全て)に含まれる成分の融着物516によって接合されている。
図8は、本発明の第七実施形態に係る座席用表皮材の積層構造を模式的に示す断面図である。図8に示される第七実施形態に係る座席用表皮材71においては、貫通孔75の内壁が、表面層12で被覆された部分だけでなく、裏面層13や裏布14等が露出した部分が存在している。このような構造となるケースとしては、例えば、裏面からの孔開け加工の場合や、表面層12の加熱押圧によるダメージを防ぐために加熱押圧の条件を弱くした場合などが挙げられる。この場合、表面層12及び/又は裏面層13に含まれる成分の融着物が必ずしも存在するとは限らない。このような第七実施形態の座席用表皮材71によっても、当該座席用表皮材71が備える貫通孔75により蒸れ感を抑えることができるとともに、意匠性や耐久性を向上することできる。なお、第七実施形態に係る座席用表皮材71の製造に際しては、貫通孔75を形成するのに適した形状の型押部77が用いられる。
上記の実施形態においては、エンボス加工法(平板エンボス加工法)により座席用表皮材11,21,31,41,51A~51D,61A~61D,71を製造する例を示したが、ウェルダー加工法により座席用表皮材11,21,31,41,51A~51D,61A~61D,71を製造することもできる。図示による詳細説明は省略するが、ウェルダー加工法においては、型押部17,27,37,47,57A~57Dを取り付けた可動定盤と、固定定盤上の絶縁紙との間に、基材70を通し、高周波により加熱された型押部17,27,37,47,57A~57Dによって、基材70を加熱押圧することで貫通孔15,25,55A,55B、又は陥没孔35,45,55C,55Dを形成する。ウェルダー加工法に用いられる型押部17,27,37,47,57A~57Dの形状については、エンボス加工法と同様の形状を用いることができる。ウェルダー加工法に用いられる絶縁紙としては、例えば、シリコーンシート、テフロン(登録商標)シート、ベークライト板、紙等が挙げられ、これらを単独、又は組み合わせて使用することができる。なかでも、貫通孔15,25,55A,55Bの形成し易さの観点から、紙を用いることが好ましい。なお、ウェルダー加工法においても、上記のエンボス加工法と同様に、型押部の損傷を防いだり、貫通孔を形成する際の打抜片を効率的に除去したり、貫通孔の形成を容易にしたりするために、保護シート(例えば、フィルム等)を併せて用いることもある。
