Component for a vehicle interior and a method of assembly
View Patent ↗A component for an interior of a vehicle is provided, including a substrate, a skin cooperating with the substrate to define a cavity, and foam disposed within the cavity. The substrate includes a recess defining a side wall and a back wall. The skin includes a primary wall defining a show surface, a perimeter wall extending away from the primary wall and contacting the side wall, and a terminal wall extending away from the perimeter wall. The terminal wall further contacts and applies a force onto the back wall. The foam is disposed within the cavity such as to substantially seal at least one of the perimeter wall and the terminal wall against the substrate. The force acting on the back wall promotes a substantially flam-tight seal, thus preventing foam from leaking between the substrate and the skin.
1. A component for an interior of a vehicle comprising:
a substrate having a recess defining a side wall and a back wall;
a skin cooperating with the substrate to define a cavity, the skin having a primary wall defining a show surface at least partially defining an outer surface of the vehicle interior component, a perimeter wall extending away from the primary wall and contacting the side wall, and a terminal wall extending away from the perimeter wall, contacting the back wall, and being biased to apply a force onto the back wall; and
foam disposed within the cavity such as to substantially seal at least one of the perimeter wall and the terminal wall against the substrate.
2. A component as in claim 1 , the substrate including a substrate angled portion between the side wall and the back wall, the skin including a skin angled portion between the perimeter wall and the terminal wall, the skin angled portion having an unconstrained skin angle when the skin portion is in an unconstrained state, the substrate angled portion having a substrate angle, wherein the unconstrained skin angle is greater than the substrate angle, and wherein the skin angled portion is at least partially engaged with the substrate angled portion.
3. A component as in claim 2 , wherein the skin angled portion is completely engaged with the substrate angled portion.
4. A component as in claim 2 , wherein the skin angled portion is in a constrained state defining a constrained skin angle while engaged with the substrate angled portion.
5. A component as in claim 4 , wherein the difference between the unconstrained skin angle and the constrained skin angle is less than 30 degrees.
6. A component as in claim 5 , wherein the difference between the unconstrained skin angle and the constrained skin angle is greater than 5 degrees and less than 15 degrees.
7. A component as in claim 4 , wherein the constrained skin angle is generally equal to 90 degrees.
8. A component as in claim 2 , wherein the substrate angled portion includes a generally arcuate cross-section.
9. A component as in claim 2 , the perimeter wall including a first portion extending from the primary wall at a first angle and a second portion extending from the first portion and defining a second angle with the primary wall.
10. A component as in claim 2 , wherein the substrate angled portion at least partially defines a secondary recess, and the perimeter wall extends into the secondary recess.
11. A component as in claim 1 , the substrate including a foam trap portion cooperating with the skin to define a foam trap conduit.
12. A component as in claim 11 , wherein the foam trap portion is a groove in the side wall.
13. A component for an interior of a vehicle comprising:
a substrate having a recess defining side walls, a back wall having a first depth, and a stepped perimeter portion having a second depth;
a skin having a primary wall defining a show surface at least partially defining an outer surface of the vehicle interior component, a perimeter wall extending away from the primary wall, and a terminal wall extending at an angle that is substantially unparallel to the perimeter wall;
wherein the first depth and the second depth are measured from the show surface and the second depth is greater than the first depth; and
foam disposed within the recess such as to substantially seal the terminal wall against the stepped perimeter portion.
14. A component as in claim 13 , wherein the side walls include a first side wall connecting the back wall and the stepped perimeter portion and a second side wall extending away from the stepped perimeter portion.
15. A component as in claim 14 , wherein the first side wall and the second side wall are substantially parallel to each other.
16. A component as in claim 15 , wherein the back wall and the stepped perimeter portion are substantially parallel to each other.
17. A component as in claim 16 , wherein the first side wall and stepped perimeter portions are substantially parallel to the primary wall.
18. A component as in claim 13 , wherein the angle between the terminal wall and the perimeter wall is substantially equal to 90 degrees.
19. A component as in claim 13 , wherein the stepped perimeter portion and at least one of the two side walls are connected by an arcuate portion.
