Abstract

A vibration damping assembly for use with an automotive vehicle is provided. The assembly includes a bracket having a C-shaped receptacle, a component such as an air cleaner housing having an integrally-formed, grommet-holding cylindrical post extending therefrom attached to the bracket, and a spool-shaped isolator mounting grommet attached to the post. The post includes a proximal end integrally attached to the component and a distal end. The distal end includes at least one integrally-formed retention barb and preferably includes two spaced-apart and integrally-formed barbs. The post includes an attachment end attached to the component and an unattached end opposite the attachment end. The barbs are formed on the unattached end. Each barb includes an upper edge extending beyond the unattached end of the post. Each barb includes a ramped, grommet-passing surface. The spool-shaped isolator mounting grommet may be formed from materials such as TPO, TPE, AEM, ECO, and EPDM.

First claim

What is claimed is:

1. A vibration damping assembly for use with an automotive vehicle comprising:
a bracket having a C-shaped receptacle;
a component attachable to said bracket, said component including an integrally-formed post, said post including an end having a grommet retention barb integrally formed therewith, and
a spool-shaped isolator mounting grommet attached to said post, wherein the post is a unitary solid structure that extends completely through the spool-shaped isolator mounting grommet.

2. The vibration damping assembly of claim 1 , wherein said a spool-shaped isolator mounting grommet is formed from an elastomeric material.

3. The vibration damping assembly of claim 2 , wherein said elastomeric material is selected from the group consisting of TPO, TPE, AEM, ECO, and EPDM.

4. The vibration damping assembly of claim 1 , wherein said spool-shaped isolator mounting grommet includes a first end defined by a first radius, a second end defined by a second radius, and a tubular body formed therebetween, said tubular body including a post-passing bore.

5. The vibration damping assembly of claim 1 , wherein said post includes an attachment end attached to said component and an unattached end opposite said attachment end, said retention barb is formed on said unattached end.

6. The vibration damping assembly of claim 5 , wherein said barb includes an upper edge that extends beyond said unattached end of said post.

7. The vibration damping assembly of claim 5 , wherein said barb includes a ramped, grommet-passing surface.

8. The vibration damping assembly of claim 1 , wherein said post has a shape, said shape being selected from the group consisting of round, triangular, oval, and D-shaped.

9. The vibration damping assembly of claim 1 , wherein said spool-shaped isolator mounting grommet includes a body, said body being compressible, said body having an uncompressed diameter and a compressed diameter, said uncompressed diameter being greater than said compressed diameter, said C-shaped receptacle has an inner diameter, said uncompressed diameter of said body being greater than said inner diameter of said C-shaped receptacle.

10. The vibration damping assembly of claim 1 , wherein said spool-shaped isolator mounting grommet component includes a long axis and a slot formed along said long axis and wherein said integrally-formed post includes a grommet locator ridge, whereby said grommet locator ridge is positioned within said slot of said spool-shaped isolator mounting grommet.

11. A vibration damping assembly for use with an automotive vehicle comprising:
a bracket having a C-shaped receptacle;
a component attachable to said bracket, said component including an integrally-formed post, said post further including an end having a grommet retention barb integrally formed therewith, said barb including a ramped, grommet-passing surface, and
a spool-shaped isolator mounting grommet attached to said post, wherein the post is a unitary solid structure that extends completely through the spool-shaped isolator mounting grommet.

12. The vibration damping assembly of claim 11 , wherein said a spool-shaped isolator mounting grommet is formed from an elastomeric material.

13. The vibration damping assembly of claim 12 , wherein said elastomeric material is selected from the group consisting of TPO, TPE, AEM, ECO, and EPDM.

14. The vibration damping assembly of claim 11 , wherein said spool-shaped isolator mounting grommet includes a first end defined by a first radius, a second end defined by a second radius, and a tubular body formed therebetween, said tubular body including a post-passing bore.

15. The vibration damping assembly of claim 11 , wherein said post includes an attachment end attached to said component and an unattached end opposite said attachment end, said retention barb is formed on said unattached end.

16. The vibration damping assembly of claim 15 , wherein said barb includes an upper edge that extends beyond said unattached end of said post.

17. The vibration damping assembly of claim 11 , wherein said post has a shape, said shape being selected from the group consisting of round, triangular, oval, and D-shaped.

18. The vibration damping assembly of claim 11 , wherein said spool-shaped isolator mounting grommet includes a body, said body being compressible, said body having an uncompressed diameter and a compressed diameter, said uncompressed diameter being greater than said compressed diameter, said C-shaped receptacle has an inner diameter, said uncompressed diameter of said body being greater than said inner diameter of said C-shaped receptacle.

19. The vibration damping assembly of claim 11 , wherein said component is an air cleaner housing.

20. A vibration damping assembly for use with an automotive vehicle comprising:
a bracket having a C-shaped receptacle;
a component attachable to said bracket, said component including an integrally-formed post, said post including an end having a grommet retention barb integrally formed therewith, said barb including a ramped, grommet-passing surface, and
a spool-shaped isolator mounting grommet attached to said post, said grommet including a body, said body having an uncompressed diameter and a compressed diameter, said
uncompressed diameter being greater than said compressed diameter, said C-shaped receptacle having an inner diameter, said uncompressed diameter of said body being greater than said inner diameter of said C-shaped receptacle, wherein the post is a unitary solid structure that extends completely through the spool-shaped isolator mounting grommet.
