Reduced ultraviolet radiation transmitting, safety protected electrochromic glazing assembly
First Claim
1. A reduced ultraviolet transmitting, safety protected electrochromic vehicular glazing assembly adapted for mounting in a vehicle having an interior and an exterior, said assembly comprising:
- first, second and third spaced optically transparent panels, said first panel located closest to said exterior of said vehicle when said assembly is mounted in said vehicle, said third panel located closest to said interior of said vehicle when said assembly is mounted in said vehicle, and said second panel disposed between said first and third panels when said assembly is mounted in said vehicle;
said second and said third panels each having a front surface and an opposing rear surface, said rear surface of said second panel facing and spaced from said front surface of said third panel and defining a space between said second and third panels, said rear surface of said second panel and said front surface of said third panel each being coated with a transparent electrical conductor;
an electrochromic medium disposed in said space whose light transmittance is variable upon the application of an electric field thereto;
ultraviolet radiation reducing means incorporated in said assembly for reducing ultraviolet radiation transmission through said assembly; and
a polymeric antilacerative layer disposed on said rear surface of said third panel for preventing lacerative injuries should said third panel crack or break.

Abstract
An electrochromic glazing assembly is disclosed with reduced near-infrared radiation transmission and reduced ultraviolet (UV) radiation transmission. The assembly may include at least a pair of glass or other elements confining an electrochromic medium therebetween. Ultraviolet radiation reducing means are incorporated for reducing ultraviolet radiation transmission through the assembly. A polymeric antilacerative layer is disposed on one surface of one of the glass elements for preventing lacerative injuries. Reduced near-infrared radiation transmission means may also be included.
