Abstract
Abstract A veiwport assembly is provided for installation in the hood of a vehicle, the hood having an opening cut therein adapted to receive the viewport assembly. The viewport assembly includes a viewport having a central portion and a peripheral portion, with the viewport being of a size larger than the hood opening so that the peripheral portion of the viewport overlaps the peripheral edge of the hood opening. The overlapping portion of the viewport is provided with a tapered edge for engaging the uppersurface of the hood and for providing a smooth transition between the viewport and the hood. The viewport further includes a mounting member extending in a direction perpendicular to the viewport and extending from the viewport at a point between the peripheral and central portions thereof. The viewport assembly further includes lip means connected to the mounting member for engaging the underside of the hood to securely fasten the viewport within the hood opening. A number of alternative embodiments are disclosed in which the mounting member may be a snap-fit element, a U-shaped flange, or a clamp arrangement.
