Abstract
An automotive glazing that provides a portal (32) for receiving infrared radiation and an automotive glazing (40, 50) that defines an open pathway for infrared radiation between an infrared camera on one side of the glazing and a camera field of view on the other side of the glazing.
Claims7
A glazing for use in vehicles that include a sensing device of a type that is responsive to electromagnetic radiation, said glazing comprising:
- a first transparency that defines an outer surface and an inner surface, said inner surface of said first transparency being oppositely disposed on said first transparency from said outer surface, said first transparency having a perimeter edge between said inner surface and said outer surface, said perimeter edge defining the outer perimeter of said first transparency, said first transparency also further defining a portal between said inner surface of said first transparency and said outer surface of said first transparency and inside the perimeter edge of said first transparency;
- a second transparency that defines an outer surface and an inner surface, said inner surface of said second transparency being oppositely disposed on said second transparency from said outer surface of said second transparency, said second transparency being oriented with respect to said first transparency such that said inner surface of said second transparency faces said inner surface of said first transparency, at least a portion of said second transparency covering the portal of said first transparency;
- a third transparency that defines an outer surface and an inner surface that is oppositely disposed on said third transparency from said outer surface of said third transparency, said third transparency being oriented with respect to said first transparency such that said inner surface of said third transparency faces the inner surface of said first transparency and a portion of the outer surface of said third transparency faces a portion of the inner surface of said second transparency, said third transparency defining a portal that coincides with the portal of said first transparency;
- and
- an interlayer that is located between the inner surface of said first transparency and the inner surface of said third transparency, said interlayer defining a portal that coincides with the portal of said third transparency and with the portal of said first transparency;
- and
- a subframe that is secured to said first transparency near the edge of the portal of said first transparency, said subframe also being connected to said second transparency to maintain said second transparency in covering relationship with the entire portal of said first transparency and the entire portal of the third transparency.

- a second transparency that defines an outer surface and an inner surface, said inner surface of said second transparency being oppositely disposed on said second transparency from said outer surface of said second transparency, said second transparency being made of zinc sulfide and oriented with respect to said first transparency such that said inner surface of said second transparency faces said inner surface of said first transparency, at least a portion of said second transparency covering the portal of said first transparency;
- a third transparency that defines an outer surface and an inner surface that is oppositely disposed on said third transparency from said outer surface of said third transparency, said third transparency being oriented with respect to said first transparency such that said inner surface of said third transparency faces the inner surface of said first transparency and a portion of the outer surface of said third transparency faces a portion of the inner surface of said second transparency, said third transparency defining a portal that extends between said inner surface of said third transparency and said outer surface of said third transparency, said portal of said third transparency coinciding with the portal of said first transparency;
- and
- a subframe that is secured to said first transparency near the edge of the portal of said first transparency, said subframe also being connected to said second transparency to maintain said second transparency in covering relationship with the entire portal of said first transparency and the entire portal of the third transparency.
