US12759266 - Curved anti-ballistic glass armor with argon chamber for car windows and manufacturing method

The present invention belongs to the field of shielding mechanics for personal protective equipment and more specifically relates to the external shielding of a transparent glass or armor curved and laminated on its periphery, which has an argon chamber for automobile windows that does not requires modification of door or window frames; since it proposes a new solution with a reinforced flange that is established in the armor and not in the frame of the vehicle, made up of a perimeter steel flange, glass of different sizes, reinforcing polycarbonates and an argon chamber that makes it light, thin, which does not fog up due to temperature changes and blocks external bullet impacts but is permissive to the passage of bullets towards the outside of the vehicle due to internal impact.

The invention describes a curved anti-ballistic glass armor designed for automobile windows, featuring an argon chamber and a reinforced flange that allows for installation without modifying vehicle frames. This lightweight and thin armor effectively blocks external bullet impacts while permitting internal bullet passage, enhancing safety without compromising visibility.

Claim 1

1 . A curved antiballistic glass armor comprising: an external section having first and second glass sheets of equal size, the first and second glass sheets laminated with an ionoplast layer; an internal section having first and second polycarbonate sheets of equal size, the first and second polycarbonate sheets laminated with a polyurethane layer; wherein the internal section has a lateral dimension in a first direction less than a lateral dimension of the external section in the first direction, such that a portion of the external section extends beyond a periphery of the internal section and forms a flange; wherein the external section is spaced from the internal section by a double-sided tape, the double-sided tape extending along a periphery of the internal section and partially defining an air chamber containing argon; wherein the external section, the internal section, and the double-sided tape are joined and sealed with a urethane edge component extending along a periphery of the internal section; and the urethane edge component comprises two perforation regions, and the curved antiballistic glass armor has a maximum thickness of 15 mm. an external section having first and second glass sheets of equal size, the first and second glass sheets laminated with an ionoplast layer; an internal section having first and second polycarbonate sheets of equal size, the first and second polycarbonate sheets laminated with a polyurethane layer; wherein the internal section has a lateral dimension in a first direction less than a lateral dimension of the external section in the first direction, such that a portion of the external section extends beyond a periphery of the internal section and forms a flange; wherein the external section is spaced from the internal section by a double-sided tape, the double-sided tape extending along a periphery of the internal section and partially defining an air chamber containing argon; wherein the external section, the internal section, and the double-sided tape are joined and sealed with a urethane edge component extending along a periphery of the internal section; and the urethane edge component comprises two perforation regions, and the curved antiballistic glass armor has a maximum thickness of 15 mm. wherein the internal section has a lateral dimension in a first direction less than a lateral dimension of the external section in the first direction, such that a portion of the external section extends beyond a periphery of the internal section and forms a flange; wherein the external section is spaced from the internal section by a double-sided tape, the double-sided tape extending along a periphery of the internal section and partially defining an air chamber containing argon; wherein the external section, the internal section, and the double-sided tape are joined and sealed with a urethane edge component extending along a periphery of the internal section; and the urethane edge component comprises two perforation regions, and the curved antiballistic glass armor has a maximum thickness of 15 mm.
