Vehicle window unit
A vehicle window unit that includes side curved regions that are arranged, in the installed state, near a, in particular standing, pillar of the vehicle body, wherein the curved regions are at least partially coloured in a transmittance reducing manner. The degree of colouration correlates with the degree of curvature.
1. A vehicle window unit that includes side curved regions that are arranged, in an installed state, near a pillar of the vehicle body,
wherein the curved regions are at least partially coloured in a transmittance reducing manner,
wherein the degree of colouration changes as a function of location, and wherein the degree of colouration correlates with the degree of curvature.
2. The vehicle window unit according to claim 1 , wherein the curvature in the side curved regions is more pronounced than an averaged curvature of the pane.
3. The vehicle window unit according to claim 1 , wherein a radius of curvature in the side curved regions is less than 300 mm.
4. The vehicle window unit according to claim 1 , wherein in the side curved regions a gradient of radii of curvature of at least 10 occurs.
5. The vehicle window unit according to claim 1 , implemented as a front window unit of a passenger means of transportation, wherein the coloured curved regions are those that are positioned, in the installed state, near an A-pillar of the vehicle body.
6. The vehicle window unit according to claim 1 , implemented as a rear window unit of a passenger means of transportation, wherein the coloured curved regions are positioned, in the installed state, near a C-pillar of the vehicle body.
7. The vehicle window unit according to claim 1 , implemented as a glass roof unit of a passenger means of transportation, wherein a coloured curved region is provided at least at or near a narrow side edge of the glass roof unit, which is positioned, in the installed state, at a border strut of a roof of the vehicle body.
8. The vehicle window unit according to claim 1 , implemented as a panoramic vehicle window of a passenger means of transportation (windshield to side window/windshield to roof pane/roof pane to rear window/rear window to side window) wherein a coloured curved region is provided at least at or near a narrow side edge of the roof pane.
9. The vehicle window unit according to claim 1 , wherein the colouration of curved regions is designed such that a reduced transmittance is between 50% and 75% of a transmittance of a rest of a window area.
10. The vehicle window unit according to claim 1 , wherein a degree of colouration changes as a function of a distance from an associated side edge.
11. The vehicle window unit according to claim 10 , wherein the colouration is less pronounced toward edges of each coloured region such that the transmittance increases toward the edges.
12. The vehicle window unit according to claim 1 , wherein the glass itself, a coating on the glass, or a polymeric film inserted into a composite glass is coloured in the coloured curved regions.
13. The vehicle window unit according to claim 1 , wherein the glass or a polymeric film inserted into a multilayer glass is imprinted in the coloured curved regions.
14. The vehicle window unit according to claim 1 , wherein the pillar is a standing pillar.
15. The vehicle window unit according to claim 3 , wherein the radius of curvature in the side curved regions is less than 200 mm.
16. The vehicle window unit according to claim 15 , wherein the radius of curvature in the side curved regions is less than 100 mm.
17. The vehicle window unit according to claim 4 , wherein in the side curved regions a gradient of radii of curvature of at least 15 occurs.
18. The vehicle window unit according to claim 17 , wherein in the side curved regions a gradient of radii of curvature of at least 20 occurs.
19. The vehicle window unit according to claim 9 , wherein the colouration of curved regions is designed such that the reduced transmittance is between 55% and 68% of the transmittance of the rest of the window area.
