Abstract

A compensating fastener assembly is configured to secure a fastener to a surface element. The compensating fastener assembly includes a compression limiter having a cylindrical main body and a flange, the cylindrical main body defining a channel and a longitudinal axis. The compensating fastener assembly further includes a spring defining a central passage. The central passage of the spring is configured to receive the main body of the compression limiter such that a first end of the spring is configured to be disposed adjacent the flange of the compression limiter.

First claim

The invention claimed is:

1. A compensating fastener assembly configured to secure a fastener to a surface element, the compensating fastener assembly comprising:
a compression limiter having a main body and a flange, the main body defining a channel and a longitudinal axis; and
a spring defining a central passage,
wherein the central passage of the spring is configured to receive the main body of the compression limiter such that a first end of the spring is configured to be disposed adjacent the flange of the compression limiter,
wherein the flange includes an annular depression area,
wherein the surface element includes an opening, and
wherein the main body of the compression limiter is configured to be inserted into the opening, the flange is configured to abut the surface element, and the spring is configured to receive the compression limiter so that the surface element is disposed between the first end of the spring and the flange of the compression limiter.

2. The compensating fastener assembly of claim 1 , wherein the main body of the compression limiter includes a recessed region, and wherein a second end of the spring is configured to be received by the recessed region.

3. The compensating fastener assembly of claim 2 , wherein the spring is configured to be compressed between the flange and a retention feature of the main body of the compression limiter.

4. The compensating fastener assembly of claim 1 , wherein the compensating fastener assembly is configured to receive a fastener in the channel of the compression limiter.

5. The compensating fastener assembly of claim 4 , wherein the spring is configured to contact and be retained between the fastener and the flange.

6. The compensating fastener assembly of claim 1 , the spring is a conical wire spring, and wherein the first end of the spring has an outer diameter greater than an outer diameter of a second end of the spring.

7. A fastener assembly, comprising:
a compression limiter having a main body extending between a first end and a second end opposite the first end, a flange extending radially outward from the second end, and an outer rim spaced apart from the flange and facing a top surface of the flange; and
a spring defining a central passage between an upper end and a lower end opposite the upper end,
wherein the spring is configured to be axially aligned with the main body and the upper end of the spring is configured to be disposed adjacent the outer rim of the compression limiter, and
wherein a surface element is disposed between the lower end of the spring and the flange of the compression limiter, and wherein the lower end of the spring is located proximate an opening of the surface element.

8. The fastener assembly of claim 7 , wherein the first end of the main body has an outer diameter that is greater than an outer diameter of a remainder of the main body.

9. The fastener assembly of claim 7 , wherein the spring is compressed between the outer rim and the surface element.

10. The fastener assembly of claim 7 , wherein a fastener includes a head and a shaft extending from the head, the shaft being configured to be at least partially inserted through the compression limiter such that a gap is formed between the shaft and the compression limiter.

11. The fastener assembly of claim 10 , wherein the upper end of the spring is configured to abut the head of a fastener.

12. A fastener assembly, comprising:
a compression limiter having a main body defining a channel therethrough and a flange extending radially outwardly from an end of the main body; and
a spring having an upper end and a lower end,
wherein the upper end of the spring is configured to be disposed adjacent the main body and a surface element is configured to be disposed between the spring and the compression limiter,
wherein the channel includes an upper ramp and a lower ramp, and
wherein the upper ramp extends inwardly relative to a longitudinal axis at an angle from an interior surface and the lower ramp extends outwardly relative to the longitudinal axis at an angle between an inner recessed surface and the interior surface of the main body.

13. The fastener assembly of claim 12 , wherein the main body of the compression limiter is configured to be received through an opening of the surface element.

14. The fastener assembly of claim 13 , wherein a gap is formed between the main body and an inner surface of the opening.

15. The fastener assembly of claim 14 , wherein a fastener is configured to be inserted through the channel of the compression limiter and an outer diameter of the fastener is greater than an inner diameter of the channel.

16. The fastener assembly of claim 15 , wherein the fastener includes a shaft extending from a head, the shaft being configured to be at least partially inserted through the channel of the main body such that a gap is formed between the shaft and the main body.

17. The fastener assembly of claim 16 , wherein the spring is configured to be compressed between the head of the fastener and the flange of the compression limiter.

18. The fastener assembly of claim 12 , wherein the spring is configured to be axially aligned with the channel of the compression limiter.
