Abstract

Interior panels for an interior of a vehicle, vehicles, and methods for making interior panels for an interior of a vehicle are provided. In one example, the interior panel includes a first trim section having a first exposed surface configured to face towards the interior. A second trim section that has a second exposed surface configured to face towards the interior is disposed adjacent to and spaced apart from the first trim section to define a gap. A first lighting array that includes light sources is configured to be disposed proximate the gap hidden from the interior by the second trim section. A controller is configured to be in communication with the first lighting array to independently direct each of the light sources to generate light that passes through the gap into the interior and illuminates the first exposed surface to define an illumination pattern.

First claim

What is claimed is:

1. An interior panel for an interior of a vehicle, the interior panel comprising:
a first trim section having a first exposed surface configured to face towards the interior;
a second trim section that has a second exposed surface configured to face towards the interior and that is disposed adjacent to and spaced apart from the first trim section to define a first gap;
a first lighting array that includes a first plurality of light sources and that is configured to be disposed proximate the first gap hidden from the interior by the second trim section; and
a controller that is configured to be in communication with the first lighting array to independently direct each light source of the first plurality of light sources to generate light that passes through the gap into the interior and illuminates at least a portion of the first exposed surface to define a first portion of an illumination pattern.

2. The interior panel of claim 1 , wherein the controller is configured to independently direct each light source of the first plurality of light sources to generate light at a corresponding illumination intensity that is variable.

3. The interior panel of claim 1 , wherein the controller is configured to receive a command signal corresponding to the illumination pattern, and wherein the controller directs the first plurality of light sources to generate light to define the first portion of the illumination pattern in response to the command signal.

4. The interior panel of claim 3 , wherein the controller is configured to be in communication with a user interface that generates the command signal in response to user selection of the illumination pattern from a plurality of selectable illumination patterns.

5. The interior panel of claim 1 , wherein the second trim section has a first channel that extends on a side opposite the second exposed surface proximate to the first gap, and wherein the first lighting array is disposed in the first channel.

6. The interior panel of claim 5 , wherein the second trim section has a lower trim portion disposed adjacent to and extending transversely away from the first trim section to an upper trim portion that extends transversely and generally upward from the lower trim portion, and wherein the lower trim portion is spaced apart from the first trim section to define the first gap.

7. The interior panel of claim 6 , wherein the interior panel further includes a third trim section that has a third exposed surface configured to face towards the interior and that is disposed adjacent to and spaced apart from the upper trim portion of the second trim section to define a second gap, wherein the interior panel further includes a second lighting array that includes a second plurality of light sources and that is configured to be disposed proximate the second gap hidden from the interior by the second trim section, and wherein the controller is configured to be in communication with the second lighting array to independently direct each light source of the second plurality of light sources to generate light that passes through the second gap into the interior and illuminates at least a portion of the third exposed surface to define a second portion of the illumination pattern.

8. The interior panel of claim 7 , wherein the first portion of the illumination pattern and the second portion of the illumination pattern define the illumination pattern.

9. The interior panel of claim 7 , wherein the second trim section has a second channel that extends on a side opposite the second exposed surface proximate to the second gap, and wherein the second lighting array is disposed in the second channel.

10. The interior panel of claim 1 , wherein the illumination pattern varies as a function of time.

11. The interior panel of claim 1 , wherein the first plurality of light sources are light-emitting diodes.

12. A vehicle comprising:
a vehicle structure having an interior; and
an interior panel disposed in the vehicle, the interior panel comprising:
a first trim section having a first exposed surface facing towards the interior;
a second trim section that has a second exposed surface facing towards the interior and that is disposed adjacent to and spaced apart from the first trim section to define a first gap;
a first lighting array that includes a first plurality of light sources and that is disposed proximate the first gap hidden from the interior by the second trim section; and
a controller in communication with the first lighting array to independently direct each light source of the first plurality of light sources to generate light that passes through the first gap into the interior and illuminates at least a portion of the first exposed surface to define a first illumination pattern.

13. The vehicle of claim 12 , wherein the controller is configured to independently direct each light source of the first plurality of light sources to generate light at a corresponding illumination intensity that is variable.

14. The vehicle of claim 13 , wherein the vehicle further includes a user interface that generates a command signal in response to user selection of the illumination pattern from a plurality of selectable illumination patterns, and wherein the controller is in communication with the user interface to receive the command signal, and wherein the controller directs the first plurality of light sources to generate light to define the first portion of the illumination pattern in response to the command signal.

15. The vehicle of claim 14 , wherein the second trim section has a first channel that extends on a side opposite the second exposed surface proximate to the first gap, and wherein the first lighting array is disposed in the first channel.

16. The vehicle of claim 15 , wherein the second trim section has a lower trim portion disposed adjacent to and extending transversely away from the first trim section to an upper trim portion that extends transversely and generally upward from the lower trim portion, and wherein the lower trim portion is spaced apart from the first trim section to define the first gap.

17. The vehicle of claim 16 , wherein the interior panel further includes a third trim section that has a third exposed surface facing towards the interior and disposed adjacent to and spaced apart from the upper trim portion of the second trim section to define a second gap, wherein the interior panel further includes a second lighting array that includes a second plurality of light sources and that is disposed proximate the second gap hidden from the interior by the second trim section, and wherein the controller is in communication with the second lighting array to independently direct each light source of the second plurality of light sources to generate light that passes through the second gap into the interior and illuminates at least a portion of the third exposed surface to define a second portion of the illumination pattern.

18. The vehicle of claim 17 , wherein the controller directs the second plurality of light sources to generate light to define the second portion of the illumination pattern in response to the command signal.

19. The vehicle of claim 18 , wherein the first portion of the illumination pattern and the second portion of the illumination patter define the illumination pattern.

20. A method for making an interior panel for an interior of a vehicle, the method comprising the steps of:
obtaining a first trim section having a first exposed surface that is configu
