Description
[内装部材の配置、構成]
まず、本実施形態の内装部材の配置、構成について説明する。図1に、本実施形態の内装部材の配置図を示す。図2に、図1の枠II内の透過上面図(透過正面図)を示す。図3に、図2のIII-III方向断面図を示す。なお、図2においては、各部材の位置関係の説明の便宜上、表皮層3等を透過して、表示領域A1~D1、光源90A~90D等を示す。
加飾シート2は、表側から裏側に向かって、表皮層3と、中間層4と、意匠層5と、柔軟層7と、を備えている。図1、図2に示すように、表皮層3の表面(上面)は車室内に表出している。表皮層3は、合成皮革製であって、層状を呈している。表皮層3は透光性、柔軟性を有している。
図3に示すように、基材8は、柔軟層7の裏側に配置されている。基材8は、樹脂製であって、層状を呈している。基材8は、透光性、可撓性を有している。光源部9は、基材8の裏側に配置されている。図2、図3に示すように、光源部9は、四つの光源(LED)90A~90Dを備えている。光源90A~90Dの表面は、各々、全面的に発光可能である。光源90Aの光の照射対象は表示領域A1である。光源90Bの光の照射対象は表示領域B1である。光源90Cの光の照射対象は表示領域C1である。光源90Dの光の照射対象は表示領域D1である。
次に、本実施形態の内装部材の使用方法について説明する。図3に示すように、制御部93が光源90A~90Dを消灯している場合は、光源90A~90Dが発光しない。また、中間層4は表皮層3よりも透光性が低い。このため、使用者は、加飾シート2の表側(車室内)から意匠層5を視認しにくい。
次に、本実施形態の内装部材の作用効果について説明する。図2、図3に示すように、加飾シート2の柔軟層7は、仕切板710AB~710CDを備えている。仕切板710ABは、表側から見て、仕切板710ABを挟んで隣り合う二つの表示領域A1、B1のうち、一方の表示領域A1を照射対象とする光が、柔軟層7を介して、他方の表示領域B1に漏れ込むのを抑制することができる。並びに、仕切板710ABは、一方の表示領域B1を照射対象とする光が、柔軟層7を介して、他方の表示領域A1に漏れ込むのを抑制することができる。他の仕切板710BC~710CDについても同様である。このため、柔軟層7における光の拡散に起因する光漏れを抑制することができる。
本実施形態の内装部材と第一実施形態の内装部材との相違点は、仕切板の代わりに塗料含浸仕切部が配置されている点である。また、凹部の底部に中間部到達部が配置されている点である。ここでは、相違点についてのみ説明する。
本実施形態の内装部材と第一実施形態の内装部材との相違点は、仕切板の代わりにスリットが配置されている点である。また、凹部の側面に傾斜部が配置されている点である。ここでは、相違点についてのみ説明する。
本実施形態の内装部材と第一実施形態の内装部材との相違点は、仕切板の代わりにスペースが配置されている点である。また、凹部の底部に基底部と深底部とが配置されている点である。ここでは、相違点についてのみ説明する。
