Abstract

A vehicle interior component with an improved torque hinge is provided. The vehicle interior component may comprise a base and a cover configured to move relative to the base. The torque hinge may be coupled to the base and the cover and configured to hold the cover in any position relative to the base. The torque hinge may comprise a bushing, a brake, a clamp and a fastener configured to provide a clamping force between the clamp and brake. The bushing may be configured to move with the cover as the cover moves relative to the base to provide a frictional force against the brake. The clamp may be manufactured by an extrusion process. The clamp may comprise a curved portion and first and second extension portions extending from the curved portion. The first and second extension portions of the clamp may be substantially parallel.

First claim

What is claimed is:

1. A component for a vehicle interior comprising:
(a) a base;
(b) a cover configured to move relative to the base;
(c) a torque hinge coupled to the base configured to hold the cover in a first position relative to the base and a second position relative to the base; and
(d) a shaft configured to couple the torque hinge to the cover;
wherein the torque hinge comprises a bushing configured to move with the cover as the cover moves relative to the base to provide friction between the shaft and the bushing;
wherein the torque hinge further comprises a clamp, a brake and a fastener, wherein the fastener is configured to provide a clamping force to the clamp and the brake.

2. The component of claim 1 wherein the torque hinge further comprises a brake, and wherein the bushing is configured to provide a frictional force against the brake.

3. The component of claim 1 wherein the bushing is configured to rotate with respect to the shaft.

4. The component of claim 1 wherein the bushing is comprised of a stainless steel material.

5. The component of claim 4 wherein the bushing comprises a plating comprised of chrome.

6. The component of claim 1 wherein the clamp is comprised of at least one of (a) an aluminum alloy, (b) a copper alloy.

7. The component of claim 1 wherein the clamp is manufactured by an extrusion process.

8. The component of claim 1 comprising a gap between the shaft and the bushing wherein the gap is between 0.04 and 0.06 mm.

9. A component for a vehicle interior comprising:
(a) a base;
(b) a cover configured to move relative to the base;
(c) a torque hinge coupled to the base configured to hold the cover in a first position relative to the base and a second position relative to the base; and
(d) a shaft configured to couple the torque hinge to the cover;
wherein the torque hinge comprises a clamp, a brake and a fastener;
wherein the fastener is configured to provide a clamping force to the clamp and the brake; and
wherein the clamp comprises a curved portion, a first extension portion extending from the curved portion and a second extension portion opposite the first extension portion extending from the curved portion;
wherein the first extension portion of the clamp and the second extension portion of the clamp are substantially parallel.

10. The component of claim 9 wherein the clamp is comprised of at least one of (a) an aluminum alloy, (b) a copper alloy.

11. The component of claim 9 wherein the clamp is manufactured by an extrusion process to provide the first extension portion of the clamp substantially parallel to the second extension portion of the clamp.

12. The component of claim 9 wherein the torque hinge comprises a bushing configured to move with the cover as the cover moves relative to the base to provide friction between the shaft and the bushing.

13. The component of claim 12 wherein the bushing is configured to provide a frictional force against the brake.

14. The component of claim 12 wherein the bushing is configured to rotate with respect to the shaft.

15. The component of claim 12 wherein the bushing is comprised of a stainless steel material.

16. The component of claim 15 wherein the bushing comprises a plating comprised of chrome.

17. A method of manufacturing a component for a vehicle interior comprising the steps of:
(a) providing a base, a cover and a shaft;
(b) extruding a material to provide an extruded clamp;
(c) providing a brake and a fastener;
(d) clamping the extruded clamp and the brake with the fastener to provide a torque hinge;
(e) assembling the shaft to the base, the cover and the torque hinge.

18. The method of claim 17 comprising the steps of providing a bushing and assembling the bushing to the torque hinge.

19. The method of claim 17 wherein the material comprises at least one of (a) an aluminum alloy, (b) a copper alloy.
