US 12,053,961 B1 · Easily constructed stone chip-preventing protection film attachable to outside of automobile windshield

Abstract

The present invention relates to an easily constructed stone chip-preventing protection film attachable to the outside of an automobile windshield. The easily constructed stone chip-preventing protection film attachable to the outside of an automobile windshield, according to the present invention, comprises: a substrate film layer (100); a surface coating layer (200) disposed on the substrate film layer (100); a protective film layer (300) disposed on the surface coating layer (200); an adhesive layer (400) disposed under the substrate film layer (100); and a release film layer (500) disposed under the adhesive layer (400). By the construction described above, since the easily constructed stone chip-preventing protection film attachable to the outside of an automobile windshield, according to the present invention, includes a substrate film layer formed of a high elastic film to configure an automobile windshield protection film, the film can be gently attached and easily constructed without performing a heating process according to the shape of the windshield, so as to enhance the construction efficiency and prevent a stone chip from being caused by an impact of a small stone or a hard foreign substance.
