Abstract
Abstract A novel automotive heat reflector shield comprising aesthetic-appearing, laminated, energy saving device for excluding sunrays, having a minimum angle of incidence of 45°, from penetrating automobile roofs equipped with sunroof and T-top roof configurations. The shield is insulative and thermally, acoustically non-conductive and thermal and light reflective. The shield is affixed by attachment means to interior of automobile equipped with sunroof or T-top roof inferior to said sunroof or T-top roof. Comprising a shield for providing automobiles, whether parked or during operation with passive cooling device thermally maintaining cooler interior so as to diminish air-conditioning requirements thereby reducing fuel consumption. It also excludes road noise and serves as a safety device capable of shielding occupants of automobile equipped with sunroof or T-top roof from being ejected through said sunroof or T-top roof during collision with other automobile or object.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
An automotive heat reflector shield for excluding sun rays, having a minimum angle of incidence of 45°, from penetrating an automobile roof equipped with a transparent roof construction and having an interior rim therein, comprising in combination, a shell member made of a rigid, high impact strength plastic, a shallow flat depression on said shell member, means constituting a thermally and acoustically insulating layer carried within the boundaries of said shallow flat depression of said shell member, a thermal and light reflecting surface layer on the outer surface of said thermal and acoustic insulating layer, and attachment means for temporarily supporting said shell member on said interior rim and the interior surface of said automobile roof to cover said transparent roof construction, said attachment means including a peripheral extension of said shell member and intergal therewith.
Claim 2
Dependent Claim
136 words
An automotive heat reflector shield for excluding sun rays, having a minimum angle of incidence of 45°, from penetrating an automobile roof equipped with a transparent roof construction and having an interior rim therein, comprising in combination, a shell member made of a rigid, high impact strength plastic, a shallow flat depression on said shell member, means constituting a thermally and acoustically insulating layer carried within the boundaries of said shallow flat depression of said shell member, a thermal and light reflecting surface layer on the outer surface of said thermal and acoustic insulating layer, and attachment means for temporarily supporting said shell member on said interior rim and the interior surface of said automobile roof to cover said transparent roof construction, said attachment means including a peripheral extension of said shell member and intergal therewith.
Claim 3
Dependent Claim
32 words
The protective shield as defined in claim 1, wherein said shell is of sufficient thickness and strength to prevent ejection or serious injury to occupants through said transparent roof during any collision.
Claim 4
Dependent Claim
39 words
The protective shield for automobiles as defined in claim 1, wherein said shell has a retention lip peripherally surrounding said layers and a pressure sensitive adhesive on the interior of said shell for retaining said layers in said shell.
Claim 5
Dependent Claim
47 words
The protective shield for automobiles as defined in claim 1, wherein said thermally and acoustic insulating layer is constituted by a first flexible foam latex layer, a vinyl layer and a further latex foam layer, said vinyl layer being sandwiched between said two flexible foam latex layers.
Claim 6
Dependent Claim
44 words
The protective shield for automobiles as defined in claim 4, wherein said shell member in acrylonitrile butadiene styrene and is of such thickness dimension that the rigidity factor equals that of steel utilized in automobile roof construction having a thickness of approximately 0.025 inch.
