<1-1.自動車用合わせガラスの構成>
図1に、第1実施形態に係る自動車用合わせガラス1の正面図を示す。自動車用合わせガラス(以下、単に合わせガラスということがある)1は、自動車の窓ガラス、特にフロントに取り付けられるウインドシールドである。図1は、合わせガラス1を車内側から見た図である。なお、以下の説明において、特に断らない限り、上下は、合わせガラス1を車体に接続した状態、すなわち、図1の状態を基準に定義される。
以下、図4を参照しつつ、以上の合わせガラス1の製造方法について説明する。まず、第2面T2上にその周縁部に沿って遮蔽層15が積層され、さらに遮蔽層15の下部上に加熱素子20及び導電性基板21が積層された外側ガラス板11を用意する。さらに、外側ガラス板11と略同じ形状の主面を有する内側ガラス板12と、シート状の中間膜13とを用意する。さらに、フラットハーネス3も用意する。
<2-1.自動車用合わせガラスの構成>
次に、第2実施形態に係る自動車用合わせガラス101について説明する。合わせガラス101は、加熱素子20及び導電性基板21が中間膜13の内部に配置される点を除き、第1実施形態に係る合わせガラス1と同様の構成を有する。以下では、第1実施形態と共通する要素には同じ参照符号を付して説明を省略し、第1実施形態との差について説明する。
以下、図8を参照しつつ、以上の合わせガラス101の製造方法について説明する。まず、第2面T2上にその周縁部に沿って遮蔽層15が積層された外側ガラス板11と、外側ガラス板11と略同じ形状の主面を有する内側ガラス板12とを用意する。さらに、シート状の外側中間膜131及び内側中間膜132と、シート材50上に加熱素子20及び導電性基板21が積層された電気素子シート5を用意する。さらに、フラットハーネス3も用意する。
以上、本発明の幾つかの実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、その趣旨を逸脱しない限りにおいて、種々の変更が可能である。例えば、以下の変更が可能である。また、以下の変形例の要旨は、適宜組み合わせることができる。
上記実施形態の合わせガラスは、自動車のフロントガラスに適用されたが、自動車のリアガラス、サイドガラス等にも適用することができる。
上記実施形態では、給電点としての導電性基板21により給電される電気素子は、デアイサー2の加熱素子(導線20)であったが、他の電気素子であってもよい。例えば、合わせガラス1に搭載されるデアイサー以外の解氷用加熱素子、デフォッガーに含まれる防曇用加熱素子、アンテナ装置に含まれるアンテナ素子、調光体又は発光シートとすることができる。また、加熱素子は、導線に代えて又は加えて、ITOやFTO等から構成される面状の加熱素子として構成することもできる。フラットハーネス3から導電性基板21を介して給電される電気素子は、例示したこれらの電気素子及び合わせガラス1に搭載されるその他の様々な電気素子の中から任意に選択される、1又は複数の電気素子とすることができる。
上記実施形態では、給電点としての導電性基板21から引き出される配線は、フラットハーネス3とされたが、この例に限定されず、例えば、丸型のハーネスであってもよいし、結束されている又は結束されていない1又は複数本の電線であってもよい。
