Description
例えば、自動車のリクライニングシートを水平に倒してそのシートの上で子供が飛び跳ねた場合等に、車室中にアレルゲンが多量に舞い上がり、自動車の乗員がそのアレルゲンを吸い込こむことによってアレルギー疾患を引き起こす可能性などが指摘されている。
(1)ファブリック素材からなる表皮で被覆されている車両用シートであって、
前記車両用シートの全ての部位ではなく、天板メイン部、天板サイド部、かまち部、背裏部、及びヘッドレスト部のうちいずれか1つ以上の部位を被覆する表皮の少なくとも前記部位に抗アレルゲン処理が施されており、
抗アレルゲン処理は、表皮の裏面から芳香族ヒドロキシ化合物を有効成分とする抗アレルゲン剤を浸漬させる処理であり、抗アレルゲン処理は、3年間で44μg/m2以上のアレルゲンを低減化するように施される車両用シート。
(2)ファブリック素材からなる表皮で被覆されている車両用シートであって、
前記車両用シートの全ての部位ではなく、天板メイン部、天板サイド部、かまち部、背裏部、及びヘッドレスト部のうちいずれか1つ以上の部位を被覆する表皮の少なくとも前記部位に抗アレルゲン処理が施されており、
抗アレルゲン処理は、表皮の裏面から芳香族ヒドロキシ化合物を有効成分とする抗アレルゲン剤を浸漬させる処理であり、
抗アレルゲン処理は、5年間で73μg/m2以上のアレルゲンを低減化するように施される車両用シート。
(3)上記(1)又は(2)に記載の車両用シートであって、天板メイン部、天板サイド部、及び背裏部のうち少なくとも1つ以上の部位を被覆する表皮の少なくとも前記部位に抗アレルゲン処理が施されるとともに、かまち部及びヘッドレスト部を被覆する表皮には抗アレルゲン処理が施されておらず、
表皮に対する抗アレルゲン剤の付着量が2.0g/m2以上である、車両用シート。
12 天板メイン部
14 天板サイド部
16 かまち部
18 背裏部
20 ヘッドレスト部
すなわち、一般に、車両用シートは、皮革やファブリック素材等からなる表皮で被覆されているが、特に、ファブリック素材からなる表皮の場合には、表皮の織目や編目等の隙間に、チリダニ等のアレルゲンが多量に蓄積しているのでないかと本発明者らは予想した。
1つ目は、車両用シートに蓄積しているアレルゲンは、車室内で自然に発生したものではなく、車室外から持ち込まれたものがほとんどであるということである。すなわち、車室内のアレルゲンは、車両用シートの表皮で成虫になって成長し、あるいは死骸になったというものではなく、そのほとんどは、家の中のソファ等から乗員の衣服等に付着し、その乗員を介して車室外から持ち込まれたものであるということを、本発明者らは独自の調査によって発見した。
2つ目は、車両用シートの表皮に蓄積しているアレルゲンは、車両用シートの全ての部位に均一に蓄積しているのではなく、天板メイン部、天板サイド部、かまち部、背裏部、及びヘッドレスト部に集中しているということである。さらに、これらの部位の中でも、天板メイン部、天板サイド部、及び背裏部に特に集中しているということである。
以下、本発明に係る車両用シートの詳細について説明する。
また、上記一般式(1)〜(6)で示される官能基を線状高分子の側鎖に有する化合物において、nの数は0〜5である。5を越えると、線状高分子を使用する効果がなくなることがある。また、Rの少なくとも1つは水酸基であり、水酸基がないと、アレルゲン低減化効果を十分発揮できないことがある。水酸基が多すぎると着色性が強くなることがあるため、水酸基は一つが好ましい。さらに、水酸基の位置は、立体障害が最も少ない箇所に結合していることが好ましく、例えば一般式(1)ではパラ位にあるのが好ましい。
よって、表皮に対する抗アレルゲン剤の付着量は、2.0g/m2以上であることが好ましい。より好ましくは、3.0g/m2以上である。
このように、表皮に対して抗アレルゲン剤を2.0g/m2以上(より好ましくは3.0g/m2以上)付着させることによって、5年間で73μg/m2以上のアレルゲンを低減化することが可能である。
Claims (3)
- ファブリック素材からなる表皮で被覆されている車両用シートであって、
前記車両用シートの全ての部位ではなく、天板メイン部、天板サイド部、かまち部、背裏部、及びヘッドレスト部のうちいずれか1つ以上の部位を被覆する表皮の少なくとも前記部位に抗アレルゲン処理が施されており、
前記抗アレルゲン処理は、表皮の裏面から芳香族ヒドロキシ化合物を有効成分とする抗アレルゲン剤を浸漬させる処理であり、
前記抗アレルゲン処理は、3年間で44μg/m2以上のアレルゲンを低減化するように施される車両用シート。 - ファブリック素材からなる表皮で被覆されている車両用シートであって、
前記車両用シートの全ての部位ではなく、天板メイン部、天板サイド部、かまち部、背裏部、及びヘッドレスト部のうちいずれか1つ以上の部位を被覆する表皮の少なくとも前記部位に抗アレルゲン処理が施されており、
前記抗アレルゲン処理は、表皮の裏面から芳香族ヒドロキシ化合物を有効成分とする抗アレルゲン剤を浸漬させる処理であり、
前記抗アレルゲン処理は、5年間で73μg/m2以上のアレルゲンを低減化するように施される車両用シート。 - 請求項1又は2に記載の車両用シートであって、
天板メイン部、天板サイド部、及び背裏部のうち少なくとも1つ以上の部位を被覆する表皮の少なくとも前記部位に抗アレルゲン処理が施されるとともに、かまち部及びヘッドレスト部を被覆する表皮には抗アレルゲン処理が施されておらず、
表皮に対する抗アレルゲン剤の付着量が2.0g/m2以上である、車両用シート。
