Abstract

A hearing protection device is presented. The device has a first earmuff connected to a second earmuff by a connector. Each of the first and second earmuffs are configured to receive an ambient sound and provide a dampened ambient sound to a wearer. The device also has a cable, with a cable length, that extends from the first earmuff to the second earmuff. The cable is coupled to the connector by a connection assembly. The connection assembly comprises a plurality of connection mechanisms arranged in a connection plan. Such a hearing protection device gives more freedom of placing the cable in a compact arrangement.

Claims (23)

1 . A hearing protection device comprising:

a first earmuff connected to a second earmuff by a connector, wherein each of the first and second earmuffs are configured to receive an ambient sound and provide a dampened ambient sound to a wearer; and

a cable, with a cable length, that extends from the first earmuff to the second earmuff, wherein the cable is coupled to the connector by a connection assembly and wherein the connection assembly comprises a plurality of connection mechanisms arranged alternatively on a first side of the connector and a second side of the connector,

wherein the plurality of connection mechanisms each comprise curvature,

wherein the plurality of connection mechanisms comprise a plurality of snap fit mechanisms configured to releasably receive the cable,

wherein the plurality of snap fit mechanisms at least partially enclose the cable.

2 . The hearing protection device of claim 1 , wherein the cable length is longer than a length of the connector.

3 . The hearing protection device of claim 1 , wherein the plurality of connection mechanisms are fixed to the connector.

4 . The hearing protection device of claim 3 , wherein the plurality of connection mechanisms are built into the connector.

5 . The hearing protection device of claim 3 , wherein the plurality of connection mechanisms are molded into the connector.

6 . The hearing protection device of claim 1 , wherein the plurality of connection mechanisms are moveable with respect to the connector.

7 . The hearing protection device of claim 1 , wherein the hearing protection device is, in a first mode, coupled to a headband and, in a second mode, coupled to a helmet.

8 . The hearing protection device of claim 1 , wherein each of the plurality of connection mechanisms has a radius of curvature that maintains a cable bend radius.

9 . A cable compaction system comprising:

A cable compaction assembly with an assembly length;

a plurality of compaction features arranged in a pattern on the cable compaction assembly, wherein the pattern causes the cable to form a meander pattern when received by the plurality of compaction features; and

wherein the plurality of compaction features are each configured to receive a portion of a cable such that a cable length is compacted to the assembly length, and wherein the plurality of compaction features are free of sharp edges;

wherein the plurality of compaction features each comprise curvature,

wherein the plurality of compaction features comprise a plurality of snap fit mechanisms configured to releasably receive the cable,

wherein the plurality of compaction features at least partially enclose the cable.

10 . The cable compaction system of claim 9 , wherein the meander pattern is a sinusoidal pattern.

11 . The cable compaction system of claim 9 , wherein the meander pattern is a lengthwise meander pattern.

12 . The cable compaction system of claim 9 , wherein the meander pattern is a widthwise meander pattern.
