Abstract: A window shade device according to the present invention serving for a significant decrease in the rising of temperature within a vehicle caused by the greenhouse effect includes a multiple-ply sheet that is the main component of the window shade device and has the required qualities of mechanical strength, low weight, good reflection of solar y radiation, and self-rolling capability. These qualities are granted to the shading sheet by its structure and y manufacturing process. The shading sheet is composed as a multiple-ply sheet, with the plies composed of materials granting most of the required qualities and tension differences, including the self-rolling capability for rolling around one single axis. The multiple-ply sheet is stored in a container that can have low aerodynamic resistance, assembled in a suitable location on a vehicle or stationary structure.

Abstract: A sunshade for use with an automobile includes a plurality of housings which can be mounted on the roof of the automobile. Each of the housings contains a flexible sunshade which is mounted on a roller. The sunshades can be unrolled to protect the front windshield, the side windows, the rear window and the roof of the automobile. Magnets are provided on the outer edges of the sunshades for attachment to the body of the automobile.

Abstract: A combination sunshade and luggage carrier which includes four housings, are arranged in a rectangular configuration. Each of the housings contains a flexible sunshade which is mounted on a roller. The housings are mounted on a linkage mechanism which is mounted in the roof of an automobile. The linkage mechanism can move the housings from a storage position in which the housings are in the confines of the automobile roof to an operating position in which the housings are above the roof In the operating position, the sunshades can be extended to protect the automobile from solar heating. Luggage may be placed in a space defined by the housings and lashed to the housing.
