An interior finish panel for a vehicle may include a panel substrate, at least two pieces of skin disposed over the panel substrate, and a foam layer. The panel substrate may include an inclined portion disposed between a base portion and at least one sealing surface. The at least two pieces of skin may include an upper skin and a lower skin joined together at a seam, wherein the seam may be at least partially disposed over the inclined portion. The seam may be sealed to a vertex of the inclined portion between the inclined portion and the sealing surface. The foam layer may be disposed between the at least two pieces of skin and the panel substrate. The foam layer may taper from the base portion towards the vertex of the inclined portion and terminate along the inclined portion before the vertex of the inclined portion.

1. A panel substrate for an interior finish panel of a vehicle comprising a base portion, an inclined portion, an upper sealing surface, and a lower sealing surface, wherein: the upper sealing surface and the lower sealing surface are non-coplanar;the inclined portion is disposed between the base portion and the lower sealing surface forming a graded transition between the base portion and the lower sealing surface such that the lower sealing surface and the base portion are non-coplanar; andthe inclined portion and the lower sealing surface form a vertex where the inclined portion and the lower sealing surface intersect wherein, when a skin layer comprising an upper skin and a lower skin is disposed over the panel substrate, the skin layer is sealed to the vertex, the upper skin and the lower skin are sealed to the upper sealing surface, one of the upper skin or the lower skin is sealed to the lower sealing surface and, when a foam layer is disposed between the skin layer and the panel substrate, the foam layer tapers between the base portion and the vertex. 2. The panel substrate of claim 1 wherein: the inclined portion is at least partially disposed between a first sidewall and a second sidewall; andthe first sidewall, the second sidewall and the inclined portion form a channel. 3. The panel substrate of claim 1 wherein the lower sealing surface is disposed between a first sidewall and a second sidewall. 4. The panel substrate of claim 3 wherein the lower sealing surface is further bounded by a back wall which extends between the first sidewall and the second sidewall. 5. The panel substrate of claim 1 wherein the upper sealing surface and the lower sealing surface are substantially parallel. 6. The panel substrate of claim 1 wherein an angle between the inclined portion and the base portion is greater than about 90°. 7. The panel substrate of claim 1 wherein an angle between the inclined portion and the at least one sealing surface is greater than about 90°. 8. The panel substrate of claim 1 wherein the at least one sealing surface and the base portion are substantially parallel. 9. An interior finish panel for a vehicle comprising a panel substrate, at least two pieces of skin disposed over the panel substrate, and a foam layer wherein: the panel substrate comprises an upper sealing surface and a lower sealing surface that are non-coplanar and an inclined portion disposed between a base portion and the lower sealing surface;the at least two pieces of skin comprise an upper skin and a lower skin joined together at a seam to form a skin layer, wherein the upper skin and the lower skin are sealed to the upper sealing surface, one of the upper skin or the lower skin is sealed to the lower sealing surface, and the seam is at least partially disposed over the inclined portion and the seam is sealed to a vertex of the inclined portion between the inclined portion and the lower sealing surface; andthe foam layer is disposed between the skin layer and the panel substrate, the foam layer tapering from the base portion towards the vertex of the inclined portion and terminating along the inclined portion before the vertex of the inclined portion. 10. The panel substrate of claim 9 wherein: the inclined portion is at least partially disposed between a first sidewall and a second sidewall; andthe first sidewall, the second sidewall and the inclined portion form a channel. 11. The panel substrate of claim 10 wherein: an angle between the inclined portion and the base portion is greater than about 90°;an angle between the inclined portion and the at least one sealing surface is greater than about 90°; andthe at least one sealing surface and the base portion are substantially parallel. 12. The interior finish panel of claim 9 wherein the seam comprises a skin lock portion and an overlap portion, wherein: the skin lock portion is disposed over the base portion of the panel substrate;the skin lock portion transitions into the overlap portion along the inclined portion; andthe overlap portion is sealed to the vertex of the inclined portion. 13. The interior finish panel of claim 12 wherein the lower sealing surface is positioned between the vertex of the inclined portion and the upper sealing surface and the overlap portion is positioned on the lower sealing surface. 14. The interior finish panel of claim 13 wherein the lower sealing surface is positioned between a first sidewall and a second sidewall. 15. The interior finish panel of claim 13 wherein the seam further comprises an edge-on-edge portion and the overlap portion transitions to the edge-on-edge portion at the upper sealing surface and the edge-on-edge portion is positioned on the upper sealing surface. 16. A method for forming a finish panel for a vehicle comprising a panel substrate, at least two pieces of skin disposed over the panel substrate, and a foam layer positioned between the panel substrate and the at least two pieces of skin, the method comprising: providing a panel substrate comprising an upper sealing surface and a lower sealing surface that are non-coplanar and an inclined portion positioned between a base portion and the lower sealing surface;positioning the panel substrate in a first mold half;providing an upper skin and a lower skin with a seam disposed between the upper skin and the lower skin;positioning the upper skin and the lower skin in a second mold half;engaging the first mold half with the second mold half such that the upper skin and the lower skin are disposed over the panel substrate and at least a portion of the seam is positioned over the inclined portion of the panel substrate such that the upper skin and the lower skin are sealed to the upper sealing surface, one of the upper skin or the lower skin is sealed to the lower sealing surface, and the seam formed by the upper skin and the lower skin is sealed to a vertex of the inclined portion and the lower sealing surface; andinjecting a foaming material between the panel substrate and the upper skin and the lower skin to form the foam layer. 17. The method of claim 16 wherein: the inclined portion of the panel substrate is at least partially disposed between a first sidewall and a second sidewall; andthe first sidewall, the second sidewall and the inclined portion form a channel. 18. The method of claim 16 wherein the seam between the upper skin and the lower skin comprises a skin lock portion and an overlap portion, wherein: the skin lock portion is disposed over the base portion of the panel substrate;the skin lock portion transitions into the overlap portion along the inclined portion; andthe overlap portion is sealed to the vertex of the inclined portion when the first mold half is engaged with the second mold half. 19. The interior finish panel of claim 18 wherein: the lower sealing surface is positioned between the vertex of the inclined portion and the upper sealing surface and the overlap portion is positioned on the lower sealing surface; andthe seam further comprises an edge-on-edge portion and the overlap portion transitions to the edge-on-edge portion at the upper sealing surface and the edge-on-edge portion is positioned on the upper sealing surface.
