Abstract

Claims (42)

1. A vehicle interior system comprising:

a polymer frame comprising a curved support surface; and

a glass substrate directly coupled to the curved support surface of the frame, the glass substrate comprising:

a first major surface;

a second major surface;

a minor surface connecting the first major surface and the second major surface; and

a thickness in a range from 0.05 mm to 2 mm, wherein:

the glass substrate has a curved shape such that the first major surface of the glass substrate includes a curved section,

the curved section of the first major surface includes a first radius of curvature greater than 30 mm and less than 5 m,

the curved support surface of the frame directly engages the first major surface of the glass substrate via a melt bond,

the direct engagement and a rigidity of the polymer frame maintains the curved shape of the glass substrate, and

the melt bond extends to the minor surface such that an edge of the polymer frame is aligned with the minor surface.

2. The vehicle interior system of claim 1 , wherein no structural adhesives are used to bond the glass substrate to the polymer frame.

3. The vehicle interior system of claim 1 , wherein the curved support surface is a convex curved surface and the curved section of the first major surface is a concave curved section.

4. The vehicle interior system of claim 3 , wherein the first major surface includes a second curved section, wherein the second curved section of the first major surface is a convex curved section.

5. The vehicle interior system of claim 1 , wherein the glass substrate comprises an asymmetric surface compressive stress distribution.

6. The vehicle interior system of claim 1 , wherein the glass substrate includes an anti-reflective coating on the first major surface.

7. The vehicle interior system of claim 1 , wherein the frame comprises any one of a center console, a dashboard, an arm rest, a pillar, a seat back, a floor board, a headrest, a door panel, a steering wheel and a portion of a housing of a free-standing display.

8. The vehicle interior system of claim 1 , wherein the vehicle is any one of an automobile, a sea craft, and an aircraft.

9. The vehicle interior system of claim 1 , wherein the glass substrate comprises cross-curvature.

10. The vehicle interior system of claim 1 , wherein the thickness is in a range from 0.7 mm to 1.5 mm.

11. The vehicle interior system of claim 1 , wherein the first radius of curvature is from about 60 mm to about 1500 mm.

12. A vehicle interior system comprising:

a polymer frame comprising a curved support surface;

a glass substrate directly coupled to the curved support surface of the frame, the glass substrate comprising:

a first major surface;

a second major surface;

a minor surface connecting the first major surface and the second major surface; and

a thickness in a range from 0.5 mm to 1.5 mm, wherein:

the glass substrate has a curved shape such that the first major surface of the glass substrate includes a curved section,

the curved section of the first major surface includes a first radius of curvature greater than 30 mm and less than 5 m,

the curved support surface of the frame directly engages the first major surface of the glass substrate via a melt bond, and

the engagement and a rigidity of the polymer frame maintains the curved shape of the glass substrate; and

a mechanical structure that is directly molded around the glass substrate and attached to the glass substrate without an adhesive, wherein the mechanical structure retains the polymer frame to the glass substrate.

13. The vehicle interior system of claim 12 , wherein no structural adhesives are used to bond the glass substrate to the polymer frame.

14. The vehicle interior system of claim 12 , wherein the curved support surface is a convex curved surface and the curved section of the first major surface is a concave curved section.

15. The vehicle interior system of claim 14 , wherein the first major surface includes a second curved section, wherein the second curved section of the first major surface is a convex curved section.

16. The vehicle interior system of claim 12 , wherein the glass substrate comprises an asymmetric surface compressive stress distribution.

17. The vehicle interior system of claim 12 , wherein the glass substrate includes an anti-reflective coating on the first major surface.

18. The vehicle interior system of claim 12 , wherein the frame comprises any one of a center console, a dashboard, an arm rest, a pillar, a seat back, a floor board, a headrest, a door panel, a steering wheel and a portion of a housing of a free-standing display.
