Abstract

A clip assembly for attaching two component assemblies while reducing NVH characteristics comprising a first clip portion; a second clip portion; and a middle clip portion that connectively spans between the first clip portion and the second clip portion; wherein the middle clip portion comprises a material that absorbs at least a portion of vibration energy that may be caused by one or both of the two component assemblies.

Claims (27)

1. A clip assembly for attaching two component assemblies while reducing NVH characteristics, comprising:

a first clip portion;

a second clip portion; and

a middle clip portion comprised of an elastomeric material with a Shore A Hardness of between 40 and 50 per ISO 868 that connectively spans between the first clip portion and the second clip portion, connected to the first and second clip portions via protrusions disposed on the first and second clip portions;

wherein the middle clip portion absorbs at least a portion of vibration energy that may be caused by one or both of the two component assemblies, further wherein the first clip portion, second clip portion, or both comprise a polyamide, a polycarbonate, a polyolefin, a vinyl, or any combination thereof and wherein a middle spanning portion has a diameter of 5.0 mm to 8.5 mm and a length of 2.0 mm to 10.0 mm.

2. The clip assembly according to claim 1 , wherein the elastomeric material is selected from a group of Natural Rubber, Synthetic Polyisoprene, Butyl rubber, Halogenated butyl rubbers, Polybutadiene, Styrene-butadiene Rubber, Nitrile Rubber, Hydrogenated Nitrile Rubbers, Chloroprene Rubber, polychloroprene, Neoprene, Baypren, ethylene propylene rubber, ethylene propylene diene rubber, Epichlorohydrin rubber, Polyacrylic rubber, Silicone rubber, Fluorosilicone Rubber, Fluoroelastomers, Perfluoroelastomers, Polyether Block Amides, Chlorosulfonated Polyethylene, and Ethylene-vinyl acetate.

3. The clip assembly according to claim 1 , wherein the first clip portion includes a laterally extending flange that provide an anti-rotational feature to the clip assembly.

4. The clip assembly according to claim 1 , wherein the first clip portion includes a wall portion that includes a constricted neck, adjoining a cavity adapted to fit a wire therein, and a locking cover.

5. The clip assembly according to claim 1 , wherein the second clip portion includes a snap-fit head.

6. A clip assembly for attaching a blower to a seat while reducing NVH characteristics, comprising:

a first clip portion including a wall portion that includes a constricted neck, adjoining a cavity adapted to fit a wire therein, and a locking cover;

a second clip portion including a snap-fit head; and

a middle clip portion that connectively spans between the first clip portion and the second clip portion;

wherein the middle clip portion comprises an elastomeric material with a Shore A Hardness of between 40 and 50 per ISO 868, further wherein the first clip portion, second clip portion, or both comprise a polyamide.

7. The clip assembly according to claim 6 , wherein a middle spanning portion of the middle clip portion has a diameter of 5.0 mm to 8.5 mm and a length of 2.0 mm to 10.0 mm.

8. A method of installing an air mover to a seat comprising the steps of:

providing a first component assembly, wherein the first component assembly comprises a wire of the seat;

providing a second component assembly, wherein the second component assembly comprises at least the air mover;

providing at least three clip assemblies, each clip comprising:

a first clip portion;

a second clip portion; and

a middle clip portion comprised of an elastomeric material with a Shore A Hardness of between 40 and 50 per ISO 868 that connectively spans between the first clip portion and the second clip portion, connected to the first and second clip portions via protrusions disposed on the first and second clip portions;

wherein the middle clip portion absorbs at least a portion of vibration energy that may be caused by one or both of the two component assemblies, further wherein the first clip portion, second clip portion, or both comprise a polyamide, a polycarbonate, a polyolefin, a vinyl, or any combination thereof;

attaching the first clip portion to the first component assembly;

repeating the above attaching step for all the clip assemblies;

attaching the second clip portion to the second component assembly; and

repeating the above attaching step for all the clip assemblies, thus installing the air mover to the seat.
