Abstract

Embodiments of a vehicle interior component and methods of forming the same are disclosed. The vehicle interior component includes a frame with a support surface and having an opening formed in the support surface. A glass substrate is provided that includes a first major surface, a second major surface facing the support surface, and a minor surface between the first and second major surfaces and defining a thickness of the glass substrate. An adhesive at least partially fills the opening and adheres the glass substrate to the frame. The adhesive in the opening acts to secure the glass substrate and adhesive to the frame.

First claim

What is claimed is:

1. A vehicle interior component comprising:
a frame comprising a curved support surface and an opening formed in the curved support surface;
a glass substrate comprising a first major surface, a second major surface facing the support surface, and a minor surface between the first and second major surfaces and defining a thickness of the glass substrate, wherein the thickness is in a range from 0.5 mm to 1.5 mm, wherein the second major surface comprises a curved substrate surface in conformance with the curved support surface, and wherein the curved support surface comprises a first radius of curvature and the curved substrate surface comprises a second radius of curvature that is from 20 mm to 10,000 mm and within 10% of the first radius of curvature, wherein the glass substrate is a cold-formed glass substrate; and
a first adhesive at least partially disposed in the opening and adhering the glass substrate to the frame,
wherein the first adhesive and the opening are configured to act in concert to prevent delamination of the vehicle interior component and to oppose elastic forces present in the glass substrate from the glass substrate being cold-formed and prevent the glass substrate from returning to an un-bent state.

2. The vehicle interior component of claim 1 , wherein the opening extends through the support surface to a void behind the support surface such that the support surface separates the void from the glass substrate, and
wherein the first adhesive is disposed in at least a portion of the void.

3. The vehicle interior component of claim 1 , wherein the opening is disposed opposite to at least one of an edge region of the second major surface and a curved portion of the second major surface.

4. The vehicle interior component of claim 1 , wherein the opening is disposed opposite to a region of the second major surface that comprises a bending-induced stress.

5. The vehicle interior component of claim 1 , wherein the first adhesive comprises at least one of an epoxy, a silicone material, an acrylic, a cyanoacrylate, a urethane, or an epoxy acrylate.

6. The vehicle interior component of claim 1 , wherein the opening does not extend to a rear surface of the frame opposite to the curved support surface.

7. The vehicle interior component of claim 1 , wherein the glass is chemically strengthened.

8. The vehicle interior component of claim 1 , further comprising a display module attached to the frame.

9. A vehicle interior system comprising the vehicle interior component of claim 1 , and a decorative layer on one of the first and second major surfaces of the glass substrate.

10. The vehicle interior system of claim 9 , wherein the vehicle interior system is at least one of a dashboard, a center console, an instrument cluster, a display, an infotainment module, a steering wheel, a touch panel, and an interior door panel.

11. A vehicle interior component comprising:
a frame comprising a support surface, a rear surface opposite to the support surface, and one or more openings formed in the support surface;
a glass substrate comprising a first major surface, a second major surface facing the support surface, and a minor surface between the first and second major surfaces and defining a thickness of the glass substrate, wherein the thickness is in a range from 0.5 mm to 1.5 mm; and
a bonding layer between the glass substrate and the frame, the bonding layer configured to adhere the glass substrate to the frame,
wherein the bonding layer is disposed on the support surface, in the one or more openings, and on at least a portion of the rear surface,
wherein the glass substrate is cold-formed onto the bonding layer to conform to a shape of the support surface such that the second major surface comprises a radius of curvature that is from 20 mm to 10,000 mm,
wherein the bonding layer is configured to oppose elastic forces present in the glass substrate from the glass sibstrate being cold-formed and prevent the glass substrate from returning to an un-bent state.

12. The vehicle interior component of claim 11 , wherein the bonding layer comprises at least one of an epoxy, a silicone material, an acrylic, a cyanoacrylate, a urethane, an epoxy acrylate, or polydimethylsiloxane.

13. The vehicle interior component of claim 12 , wherein the bonding layer optionally comprises polydimethylsiloxane and wherein, when the bonding layer comprises polydimethylsiloxane, the bonding layer is plasma-bonded to the second major surface of the glass substrate.

14. The vehicle interior component of claim 11 , wherein the support surface comprises a curved support surface.
