Abstract

A trim element for a device includes a substrate formed from a material. The material has a first coefficient of static friction and a first coefficient of kinetic friction with respect to the device. The trim element includes a cured film disposed on the substrate and formed from a coating composition. The cured film has a second coefficient of static friction that is greater than the first coefficient of static friction and a second coefficient of kinetic friction that is greater than the first coefficient of kinetic friction. A device includes a body and the trim element attached to the body. In one embodiment, the device includes a component attached to the body and pivotable between an open position and a closed position.

First claim

The invention claimed is:

1. A device comprising:
a body having a flange;
a trim element disposed on the flange, wherein the trim element includes:
a substrate formed from a material; and
a cured film disposed on the substrate and formed from a coating composition; and

a component attached to the body and pivotable between an open position in which the component is spaced apart from the trim element and a closed position in which the component is disposed in fixed contact with the trim element;
wherein the material has a first coefficient of static friction with respect to the component and a first coefficient of kinetic friction with respect to the component;
wherein the cured film has a second coefficient of static friction with respect to the component that is greater than the first coefficient of static friction and a second coefficient of kinetic friction with respect to the component that is greater than the first coefficient of kinetic friction.

2. The device of claim 1 , wherein the substrate has an attachment portion configured for attaching to the body and a bulbous portion extending from the attachment portion.

3. The device of claim 2 , wherein the cured film is disposed on the bulbous portion.

4. The device of claim 1 , wherein the body is disposed in a plane, and further wherein the component is not translatable with respect to the trim element in a direction parallel to the plane when the component is disposed in the closed position.

5. The device of claim 1 , wherein the cured film dampens movement of the component with respect to the body when the component is disposed in the closed position.

6. The device of claim 1 , wherein the component is cohered to the body when the component is disposed in the closed position.

7. The device of claim 1 , wherein the component is a liftgate and the trim element is a seal disposed along the flange.

8. A device comprising:
a body;
a component attached to and pivotable with respect to the body;
a trim element disposed on the component, wherein the trim element includes:
a substrate formed from a material; and
a cured film disposed on the substrate and formed from a coating composition; and

wherein the component is pivotable with respect to the body between an open position in which the trim element is spaced apart from the body and a closed position in which the trim element is disposed in fixed contact with the body;
wherein the material has a first coefficient of static friction with respect to the component and a first coefficient of kinetic friction with respect to the component;
wherein the cured film has a second coefficient of static friction with respect to the component that is greater than the first coefficient of static friction and a second coefficient of kinetic friction with respect to the component that is greater than the first coefficient of kinetic friction.

9. The device of claim 8 , wherein the substrate has an attachment portion configured for attaching to the component and a bulbous portion extending from the attachment portion.

10. The device of claim 9 , wherein the cured film is disposed on the bulbous portion.

11. The device of claim 8 , wherein the component is cohered to the body when the component is disposed in the closed position.

12. The device of claim 8 , wherein the device is a vehicle, the component is a door, and the trim element is a seal.

13. A trim element for a device, the trim element comprising:
a substrate formed from a material, wherein the material has a first coefficient of static friction with respect to the device and a first coefficient of kinetic friction with respect to the device; and
a cured film disposed on the substrate and formed from a coating composition, wherein the cured film has a second coefficient of static friction with respect to the device that is greater than the first coefficient of static friction and a second coefficient of kinetic friction with respect to the device that is greater than the first coefficient of kinetic friction.

14. The trim element of claim 13 , wherein the second coefficient of static friction is greater than or equal to about 4.5.

15. The trim element of claim 13 , wherein the second coefficient of kinetic friction is greater than or equal to about 2.

16. The trim element of claim 13 , wherein the second coefficient of static friction is greater than or equal to about 5.

17. The trim element of claim 16 , wherein the second coefficient of kinetic friction is greater than or equal to about 5.

18. The trim element of claim 13 , wherein the coating composition is an epoxy.

19. The trim element of claim 18 , wherein the material is an elastomer.

20. The trim element of claim 19 , wherein the material is ethylene propylene diene terpolymer.
