DETAILED DESCRIPTION

[0020] Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings in which like numerals represent like elements throughout the several figures, and in which example embodiments are shown. Embodiments of the claims may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The examples set forth herein are non-limiting examples and are merely examples among other possible examples.

[0021] Some embodiments of this invention, illustrating all its features, will now be discussed in detail with respect to FIGS.2-6.

[0022] As shown in FIG. 2, a sunshade 11 is formed by a pair of resilient loop members 9 and 10 forming oval shape frames. The flexible loop members are retained in position by a peripheral loop portion of fabric 7 which includes an internal loop retaining structure. The fabric 7 is not in tension, but the fabric portion within the loop members 9 and 8 may be in tension. As an example, a pair of resilient loop members 8 and 9 forming oval shape frames may be provided by mechanically fastening (stitching), fusing, or gluing so that the loop frame members 8 and 9 are retained in position. The sunshade 11 is comprised of three layers (not shown), one being the reflective insulating material on the outside, to block the suns rays and protecting the interior of the vehicle from heat and sun damage. The second layer consists of at least two flexible oval shaped loops 8 and 9 made of flexible material (for e.g. a flexible metal strip or wire, spring metal, flexible steel and the like), each flexible oval shaped loops 8 and 9 include two endpoints connected by a Zig-Zag clamping mechanism or device 10. The at least two flexible oval shaped loops 10 placed in proper support locations in the sunshade. With the final layer being the vinyl backing seen from the interior of the vehicle, giving a cleaner cosmetic look to sunshades.

[0023] Although the loops 9 and 8 are described as formed of flexible steel and other resilient material such as plastics, spring may be used. The term fabric is to be given its broadest meaning and may include woven fabrics, sheet fabrics or even films.

[0024] As an exemplary embodiment, If we use the pair of oval sunshade shades as shown in FIG. 2 to be taller, lots of cloth wasted in overlap to make their use possible in narrow cars can be saved. The two oval-shaped sunshade shades are 33 in height, but only 26 in width (approx.)

[0025] So the total length of this shade is 1.5+26+2+26+1.5=57

[0026] Minimum width possible for narrow cars with taller windshield=26+26?2(2)=48

[0027] The total dimensions of a shade=57?38=about 33% savings in cloth material and 25% savings in length needed to make the metal circle.

[0028] This gives the versatility of taller sunshade shade in a compact design without making it bulky and costly in manufacturing cost thus retail cost.
