AUTOMOTIVE GLASS WITH VARIABLE TRANSPARENCY Russian patent published in 2019 - IPC B60J1/00 G02F1/153 B60J3/04 

FIELD: transport machine building.

SUBSTANCE: invention relates to automotive glasses and is intended for production of electrochromic automotive glass. Automotive glass comprises three superimposed glass sheets. On adjacent surfaces of first and second sheets there are electroconductive layers with fixed buses of connection of power supply source. Space between said sheets is sealed and electrochromic working substance is placed in it. All glass sheets and electroconductive layers are completely or partially transparent at least in part of visible spectrum of optical radiation. Between the third and second sheets there is a polymer layer which delays ultraviolet radiation. On the other side, a protective film which does not transmit ultraviolet radiation is glued onto the first sheet. First sheet is smaller than second sheet in contact area of vehicle glass edge with seal. When installing the glass, the third sheet is put outside the car, and the first one – inside.

EFFECT: possibility to install glass with variable transparency into standard compactor of vehicle window at simultaneous long-term operation of electrochromic layer protected from ultraviolet, and protection of glass from scratches.
