Abstract

A polymeric vehicle glazing is described, having an outer face and an inner face, with a transparent polymeric component at the outer face and the inner face. An opaque polymeric component is flush mounted at the inner face in at least one section of the transparent polymeric component.

First claim

The invention claimed is:

an interface connecting the transparent polymeric component and the opaque polymeric component and a junction point in which the transparent polymeric component, the opaque polymeric component and the ambient air meet,
a first interior face defined as the nearest parallel to the outer face that passes through the transparent polymeric component and the opaque polymeric component, and
a second interior face defined as the most distant parallel to the outer face that passes through the transparent polymeric component and the opaque polymeric component,
wherein at the junction point, the interface and the second interior face form an angle α, wherein α is 20° to 100° in direction of the first interior face,
wherein at a point of the interface that lies 0.1 mm to 1 mm beneath the inner face, the interface and the second interior face form an angle α 1 , wherein α 1 is 10° to 60° in direction of the first interior face,
wherein the first interior face defines a plane of the interface nearest to the outer face, and
wherein within at least one section of the opaque polymeric component, the inner face and the second interior face form an angle ß, wherein ß is 10° to 100° in direction of the periphery.

2. The polymeric vehicle glazing according to claim 1 ,
wherein the angle α that is formed at the junction point is 50° to 90°, in direction of the first interior face,
and wherein the point of the interface where the angle α 1 is formed lies 0.3 mm to 0.6 mm beneath the inner face, wherein α 1 is 25° to 45° in direction of the first interior face.

3. The polymeric vehicle glazing according to claim 1 , wherein the inner face comprises an adhesive surface which is identical to the second interior face, or parallel to the second interior face and is 0.5 mm to 10 mm above the second interior face.

4. The polymeric vehicle glazing according to claim 3 , wherein the adhesive surface is parallel to and 1 mm to 5 mm above the second interior face.

5. The polymeric vehicle glazing according to claim 1 , wherein the inner face comprises at least two electrical contacts and at least one conductive wire and the electrical contacts are located on the opaque polymeric component.

6. The polymeric vehicle glazing according to claim 5 , wherein the electrical contacts comprise an upper bus bar and a lower bus bar.

7. The polymeric vehicle glazing according to claim 6 , wherein the conductive wires are electrically connected to the upper bus bar and the lower bus bar and the lower bus bar is glued to the opaque polymeric component.

8. The polymeric vehicle glazing according to claim 1 , wherein the opaque polymeric component forms a circumferential frame enclosing the transparent polymeric component.

9. The polymeric vehicle glazing according to claim 1 , wherein a thickness of the transparent polymeric component is between 1 mm and 20 mm, and a thickness of the opaque polymeric component is between 0.5 mm and 15 mm.
