ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to collapsible sun shades for protecting the interior of automobiles against unwanted exposure to the sun. The sun shades of the present invention may be extended behind the windshield or windows of an automobile to act as a barrier to sunlight, reducing heat buildup within the vehicle interior and undesired weathering of the vehicle interior from exposure to sunlight.
In general, vehicle sun shades may be positioned to shield a vehicle interior from either an interior or exterior location. As an example, interior sun shades include folding cardboard sun shades for placement behind vehicle windshields such as shown in the patent to Levy, U.S. Pat. No. 4,202,396. Other types of interior windshield sun shades include fan-like venetian blind arrangements, and designs consisting of fabric supported by elongated loops of spring-like material.
In addition to the interior sun shades, exterior sun shades may also be used. For example, an exterior sun shade may consist of a thin layer of fabric or plastic to lie on the exterior surface of the windshield.
SUMMARY OF THE INVENTION
In general, in one aspect, the invention includes vehicle sunshades including a polymeric core material, a fabric covering, a series of stitches defining foldable panels, and a hinged margin around the periphery of the sun sunshade.
In general, in another aspect, the invention includes foldable vehicle sunshades including a polymeric core material, such as low or high density polyethylene or polyurethane foam,a polyethylene-terephalate coating on one side, a polyurethane coated nylon covering on another side, a series of stitches defining foldable panels, and a hinged margin around the periphery of the sunshade.
In general, in another aspect, the invention includes foldable vehicle sunshades including a polymeric core material, such as low or high density polyethylene or polyurethane foam, a nylon covering on at least one side of the polymeric core material, a series os stitches defining foldable panels, and a hinged margin around the periphery of the sunshade.
In general, in another aspect, the invention includes foldable vehicle sunshades including a polymeric core material, such as low or high density polyethylene or polyurethane foam,a polyethylene terephalate surface material on at least one side of the polymer core material, a series of stitches defining foldable panels, and a hinged margin around the periphery of the sunshade.
In general, sunshades under the present invention may be extended to form an open, or unfolded, state and may be folded to form a closed, or folded, state. Flexibility and resiliency in the materials selected to form the foldable sun shade provide a sun shade that is biased in an unfolded state, but that can also be folded to a folded state. A trimming material may be included around the periphery of the sunshade to prevent delamination of the surface material from the core material. Furthermore, the sunshades under the present invention include a restraining strap to maintain the sunshades in the closed, or folded, state.
