Abstract

A number of variations may include a product comprising a cam guide mechanism for use with a string-damper comprising a body, wherein the body includes a profiled surface and a groove extending along the profiled surface.

First claim

What is claimed is:

1. A product comprising:
a glove box hinged compartment comprising a first side surface, a second side surface, and a bottom surface; and a cam guide mechanism for a string-damper, wherein the cam guide mechanism is attached directly to the first side surface of the hinged compartment.

2. The product of claim 1 wherein the cam guide mechanism includes a profiled surface.

3. The product of claim 2 wherein the profiled surface is at least one of a smooth continuous radius shape, a variable radius shape, or a corner shape.

4. The product of claim 1 wherein the cam guide mechanism and the hinged compartment are one single continuous unit.

5. The product of claim 4 wherein the cam guide mechanism and the hinged compartment are molded.

6. The product of claim 1 further comprising a glove box frame which is constructed and arranged to remain stationary in a vehicle, wherein the string-damper is attached to the glove box frame, and wherein a string from the string-damper extends over the cam guide mechanism and is attached to the hinged compartment.

7. The product of claim 6 wherein the string is attached to the hinged compartment with an anchor clip, and wherein the anchor clip is fixed to the hinged compartment so that the anchor clip does not rotate on the hinged compartment.

8. The product of claim 6 wherein the string is attached to the hinged compartment with an anchor clip, and wherein the anchor clip is attached to the hinged compartment so that the anchor clip rotates on the hinged compartment.

9. A method comprising:
tuning of a string-damper for a hinged mechanism comprising:
providing a cam guide mechanism with a profiled surface on a side surface of a moving component of the hinged mechanism;
wrapping a string from the string-damper around the profiled surface on the cam guide mechanism and attaching the string to the moving component of the hinged mechanism; and
controlling the effective moment arm throughout the movement of the hinged mechanism with the profiled surface.

10. The method of claim 9 wherein the profiled surface is at least one of a smooth continuous radius shape, a variable radius shape, or a corner shape.

11. The method of claim 9 wherein the hinged mechanism is a glove box.

12. The method of claim 9 wherein the profiled surface of the cam mechanism is constructed and arranged to increase damping of the hinged mechanism as the hinged mechanism moves from a closed position to an open position.

13. A hinged compartment for a vehicle comprising:
a hinged compartment comprising a first side surface, a second side surface, and a bottom surface, and wherein the first side surface includes a cam mechanism having a groove;
a hinged compartment frame constructed and arranged to remain stationary in the vehicle; and
a string-damper attached to the hinged compartment frame, wherein a first end of a string from the string-damper is attached to the first side surface of the hinged compartment so that the string sits within the groove on the cam mechanism and is constructed and arranged so that the string moves fore and aft in relation to the cam mechanism as the hinged compartment is opened and closed.

14. The hinged compartment for the vehicle of claim 13 wherein the cam mechanism includes a profiled surface which is at least one of a smooth continuous radius shape, a variable radius shape, or a corner shape.

15. The hinged compartment for the vehicle of claim 14 wherein the profiled surface is constructed and arranged to increase damping of the hinged compartment as the hinged compartment moves from a closed position to an open position.

16. The hinged compartment for the vehicle of claim 13 wherein the hinged compartment is a glove box.

17. The hinged compartment for the vehicle of claim 13 wherein the cam mechanism and the hinged compartment are one continuous uninterrupted piece.

18. The hinged compartment for the vehicle of claim 17 wherein the cam mechanism and the hinged compartment are molded.
