IPC: G02B27/00
Filed: 1992-08-20
Abstract: The transparent windscreen (330) with a head-up display such as for aircraft, has two outer surfaces (340,338). At one section (342,344) the outer surfaces (340,338) are parallel to each other, and in a further section (337) they are not in parallel. Pref. the first section (342,344) is composed of two parts, and the second section (337) is between the two parts (342,344). The two parts (342,344) are of different thicknesses, and the second secton (337) is wholly enclosed by the first section (342,344), or it is not fully enclosed. In a cpd. windscreen (330) for vehicles, the two glass layers (332,334) are bonded together by an intermediate layer (336). The main surfaces (338,340) are not planar, and the glass panes (332,334) can be of coloured glass. At least one surface (338,340) of the glass panes (332,334) is coated, and the intermediate layer (336) is a thermoplastic material.
