Abstract
Description
上記車両内装部材において、前記導電糸の全体は、通電されると発熱する材料により形成されていることが好ましい。
導電糸として、上記の条件を満たす直径を有するものが用いられることで、導電糸によるゴワゴワした触感が表皮を介して感じられにくく、触感が向上する。
クッション層として、上記の条件を満たす密度を有するものが用いられた場合には、そのクッション層によって車両内装部材に、柔らかな触感が付与される。
なお、以下の記載においては、車両の前進方向を前方として説明し、車両の後進方向を後方として説明する。また、上下方向は車両の上下方向を意味し、左右方向は車幅方向であって車両の前進時の左右方向と一致するものとする。また、図3及び図4において、図面の寸法比率は、説明の都合上誇張されており、実際の比率とは異なる。
アームレスト11は、基材12上に積層されたクッション層13を備えている。クッション層13は、ウレタン等の発泡体からなる。アームレスト11では、クッション層13が、基材12上に積層された第1クッション層14と、第1クッション層14上に積層された第2クッション層15とによって構成されている。第1クッション層14は、0.16kg/m^3(「^ 」はべき乗を表わす)以下の密度を有している。これに対し、第2クッション層15は、0.05kg/m^3以下であって、第1クッション層14よりも低い密度を有している。第1クッション層14と第2クッション層15とで、密度を異ならせることは、発泡倍率を異ならせることで可能である。
本実施形態の織布部18では、隣り合う一対の緯糸22(導電糸)の間に2本の緯糸23(非導電糸)が位置するように、緯糸22,23が配置されている。
図4に示すように、パームレスト31は、クッション層の構成の点でアームレスト11と異なっている。すなわち、アームレスト11におけるクッション層13が、第1クッション層14及び第2クッション層15の2層構造を採っているのに対し、パームレスト31におけるクッション層32は、第2クッション層15のみの1層構造を採っている。パームレスト31の上記以外の構成は、アームレスト11と同様である。そのため、パームレスト31においてアームレスト11と同様の構成要素には同一の符号を付し、重複する説明を省略する。
上記のように、アームレスト11とパームレスト31とで表皮27の表面の目標温度に差を設定しているのは、アームレスト11では表皮27の熱が衣服を通じて間接的に肘に伝わるのに対し、パームレスト31では表皮27の熱が手首に直接伝わるからである。
不織布等の布帛上に電熱線を貼付けて配線した従来のヒータ層では、電熱線が布帛から厚み方向に突出する。また、上記のように布帛の外部に配線される電熱線の耐久性等を考慮すると、同電熱線として径の大きなものが用いられることになる。従って、ヒータ層が組込まれた従来の車両内装部材(アームレスト、パームレスト等)に肘、手首等を乗せて荷重をかけると、電熱線によるゴワゴワした触感が表皮を介して感じられる。
・導電糸として、全体が、通電されると発熱する材料によって形成されたものが用いられている。そのため、導電糸の全体が通電により発熱する。従って、導電糸の一部、例えば、外表面のみが、通電されると発熱する材料によって形成されている場合に比べ、導電糸を効率よく発熱させることができる。
・ヒータ層16は、主要部が織布部18によって構成されているため、薄く嵩張りにくい。ヒータ層16が、アームレスト11やパームレスト31において、同ヒータ層16の厚み方向に占めるスペースが小さくてすむ。
なお、上記実施形態は、これを以下のように変更した変形例として実施することもできる。上記実施形態及び以下の変形例は、技術的に矛盾しない範囲で互いに組合わせて実施することができる。
・織布部18における緯糸22が導電糸によって構成され、緯糸23が非導電糸によって構成される場合、隣り合う緯糸22間に位置する緯糸23の数が、上記実施形態(2本)とは異なる数に変更されてもよい。緯糸23の数が多くなるに従い、織布部18で発生される熱量が少なくなる。
・織布部18における全ての緯糸22,23が導電糸によって構成されてもよい。
・織布部18は、平織とは異なる織り方、例えば、斜文織(綾織)、朱子織等によって織られたものであってもよい。
・導電糸として、全体が、通電により発熱する材料であることを条件に、金属とは異なる材料によって形成された糸が用いられてもよい。
・本発明における車両内装部材の適用対象は、アームレスト11のみであってもよいし、パームレスト31のみであってもよい。
<その他>
・表皮27における表面の目標温度が、アームレスト11とパームレスト31とで同一に設定されてもよい。
