Definitions
- the present invention relates to a laminated glass for an automobile.
- a laminated glass for automobiles a laminated glass having an outer glass plate and an inner glass plate and an interlayer film inserted between the two glass plates is widely used.
- an electric element such as a heating element for a deicer, a heating element for anti-fog, and an antenna element is often mounted mainly on the peripheral portion of the inner surface of the outer glass plate.
- a part of the peripheral portion of the inner glass plate is cut out so that the presence of the inner glass plate and the intermediate film does not hinder the inner glass plate and the intermediate film. It is configured not to exist.
- the sealing property between the outer glass plate and the intermediate film may be reduced. More specifically, water may enter through a gap between the outer glass plate from which the harness is drawn out and the interlayer film, and may impair the function of the electric element and / or the power supply point on the inner surface of the outer glass plate.
- the electric element and the feeding point may be arranged inside the intermediate film instead of the inside surface of the outside glass plate.
- an electric element and a feeding point are sandwiched between two intermediate films and then bonded to each other.
- a gap is formed around the harness inside the intermediate film. Or, a problem of flooding of the power supply point may occur.
- An object of the present invention is to provide a laminated glass for automobiles that can suppress inundation of an electric element and / or a power supply point.
- the laminated glass for an automobile includes an outer glass plate, an inner glass plate, an intermediate film, an electric element, a power supply point for supplying power to the electric element, and wiring.
- the outer glass plate has a first surface and a second surface located on the vehicle interior side with respect to the first surface.
- the inner glass plate has a third surface and a fourth surface located on the vehicle interior side with respect to the third surface.
- the intermediate film is disposed between the outer glass plate and the inner glass plate, and joins the second surface and the third surface.
- the electric element and the power supply point are arranged on the second surface or inside the intermediate film near a peripheral portion of the second surface.
- the wiring is connected to the feed point, exits the feed point, and passes through the intermediate film toward the third surface.
- the laminated glass for an automobile according to the second aspect of the present invention is the laminated glass for an automobile according to the first aspect, wherein the wiring is a flat harness.
- An automotive laminated glass according to a third aspect of the present invention is the automotive laminated glass according to the first aspect or the second aspect, wherein at least one peripheral edge of the second surface and the fourth surface has a shield. A layer is formed, the intermediate film is in contact with the shielding layer, and the feeding point is at least partially disposed on the shielding layer.
- the laminated glass for an automobile according to a fourth aspect of the present invention is the laminated glass for an automobile according to any one of the first to third aspects, wherein the wiring passes through the intermediate film, and It advances between a surface and the intermediate film, and is drawn out from between the third surface and the intermediate film.

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。
