Abstract

A vehicle window includes a pane of self-darkening or laminated glass and a function layer made of a low-emission material disposed on an inside surface of the pane. The function layer reflects a first infrared radiation into the vehicle and reduces an emission of a second infrared radiation from the glass pane into an interior of the vehicle. In addition, a method for regulating a thermal comfort of a passenger in an interior of a vehicle includes the steps of providing a self-darkening glazing as protection against glare and heat, disposing an IR-reflecting transparent layer on the glazing in form of a coating or film, reflecting an infrared radiation emitted from the vehicle interior back into the vehicle interior using the IR-reflecting transparent layer, and reducing a heat radiated by the glazing into the vehicle interior.

Claims

1. A self-darkening laminated vehicle window for a vehicle, the vehicle window comprising:

an outer glass pane;

an inner glass pane;

a function layer made of a low-emission material having an emission factor for infrared radiation of less than 0.5 disposed on an inside surface of the inner glass pane; and

a suspended particle device film disposed between the inner glass pane and the outer glass pane and in contact with the inner glass pane and the outer glass plane, wherein the vehicle window has a dark transmission of less than or equal to 5% and a bright transmission of more than 20%.

2. The vehicle window as recited in claim 1, wherein at least one of the inner and outer glass panes includes electrochrome glass.

3. The vehicle window as recited in claim 1, wherein at least one of the inner and outer glass panes includes primarily silicate glass.

4. The vehicle window as recited in claim 1, wherein the low-emission material includes electrically conductive SnO compounds.

5. The vehicle window as recited in claim 4, wherein the SnO compound includes at least one of indium oxide and metal fluoride.

6. The vehicle window as recited in claim 1, wherein the function layer includes one of a coating or a film of the low-emission material having a thickness ranging from 50 nm to 500nm.

7. The vehicle window as recited in claim 1, wherein the dark transmission and the bright transmission values of the vehicle window are determined independent of a shading of an additional mechanical shading device.
