Headliner for a vehicle
A headliner for a vehicle includes a substrate that attaches to, and covers a roof panel, the substrate defining a groove on a first side formed around an entirety of a periphery of an area of the roof panel, wherein the groove is continuous around the periphery. A light emitting material is disposed within the groove formed in the substrate and is uninterrupted around the periphery within the groove.
1. A headliner for a vehicle, comprising:
a substrate that attaches to, and covers a roof panel, the substrate spanning a substantially entire length and a substantially entire width of the roof panel, the substrate defining a groove on a first side formed around an entirety of a periphery of an area of the roof panel to emphasize a feature on the headliner, wherein the area is configured to receive a sunroof or a moonroof, and wherein the groove is continuous around the periphery; and
a light emitting material disposed within the groove formed in the substrate, and being uninterrupted around the periphery within the groove.
2. The headliner of claim 1 , wherein the groove defines first and second sections, the first section having a width being less than a diameter of the second section and a diameter of the light emitting material.
3. The headliner of claim 1 , wherein the sunroof or moonroof comprises a window such that the light emitting material extends around a periphery of the window.
4. The headliner of claim 1 , wherein the substrate is configured to be heated on a second side to form the groove.
5. The headliner of claim 1 , wherein the groove is formed at a predetermined distance into the headliner from the first side toward a second side such that the light emitting material and first side are flush.
6. The headliner of claim 5 , wherein the predetermined distance is between 2 to 3 millimeters.
7. The headliner of claim 1 , wherein the groove is formed by a mandrel having an end such that first and second portions of the mandrel are oppositely oriented and expand away from a center of the mandrel to a distance greater than a diameter of the light emitting material.
8. A vehicle, comprising:
a roof panel having a headliner attached thereto, the headliner spanning a substantially entire length and a substantially entire width of the roof panel, wherein the headliner includes a groove, being continuous, formed around an entirety of a periphery of an area to emphasize a feature on the headliner,
a sunroof or moonroof received within the area; and
a light emitting material disposed within the groove such that light from the light emitting material is directed toward an interior of the vehicle.
9. The vehicle of claim 8 , wherein the headliner includes a substrate having a first side, and a second side, wherein the groove and light emitting material are disposed on the first side of the substrate.
10. The vehicle of claim 9 , wherein the groove is formed with a mandrel having an end that expands the first side of the substrate in response to a plunger sliding within the mandrel in a direction of the second side with heat being applied to the second side.
11. The vehicle of claim 10 , wherein the end of the mandrel includes two, oppositely oriented portions that expand to a width greater than a diameter of the light emitting material.
12. The vehicle of claim 8 , wherein the groove is molded in a headliner form tool to match a contour of the headliner.
13. The vehicle of claim 8 , wherein the groove defines a depth such that the light emitting material is flush with the substrate of the headliner.
14. The vehicle of claim 8 , wherein the groove is continuous such that the light emitting material extends around the periphery of a window being the area to emphasize a feature on the headliner, uninterrupted.
15. A method of forming a headliner for a vehicle comprising:
forming a substrate having first and second sides and configured to span a substantially entire width and a substantially entire length of a roof panel, the substrate defining an area configured to receive a sunroof or a moonroof;
heating the second side of the substrate;
driving a mandrel into the first side of the substrate;
actuating a plunger through the mandrel such that first and second portions of the mandrel expand away from a center of the plunger to form a groove within the first side of the substrate; and
retracting the plunger and mandrel from the substrate.
16. The method of claim 15 further comprising inserting a light emitting material into the groove.
17. The method of claim 16 , wherein inserting the light emitting material into the groove includes extending the light emitting material around a periphery of a roof panel, the light emitting material being uninterrupted around the periphery.
18. The method of claim 15 further comprising forming the groove to match a contour of the headliner.
19. The method of claim 15 , wherein actuating the plunger defines a depth of the groove such that the light emitting material is flush with the second side of the substrate.
20. The method of claim 15 , wherein the first and second portions of the mandrel expand to a diameter greater than a diameter of the light emitting material.
