Pivot-Arm Assembly for a Helmet Mounted Headset
First Claim
1. A pivot-arm assembly for attaching an ear cup to a mounting feature on an exterior of a helmet, the pivot-arm assembly comprising:
- a mount configured to releasably couple to the mounting feature;
an arm having a first end configured to couple to the ear cup and a second end;
a hinge rotatable about a first axis and about a second axis, the hinge being coupled to the second end of the arm and disposed between the arm and the mount such that the first end of the arm is rotatable relative to the mount about the first axis and the first end of the arm is rotatable relative to the mount about the second axis; and
a biasing member coupled to the arm and configured to spring bias the first end of the arm relative to the mount in a rotatable direction about the second axis of the hinge.

Abstract
A pivot-arm assembly is provided for attaching an ear cup to a mounting feature on an exterior of a helmet. The pivot-arm assembly comprises a mount configured to releasably couple to the mounting feature. A hinge is rotatable about a first axis and about a second axis. The hinge is coupled to a second end of the arm and disposed between the second end of the arm and the mount such that the first end of the arm is rotatable relative to the mount about the first axis and the first end of the arm is rotatable relative to the mount about the second axis. A biasing member is coupled to the arm and is configured to spring bias the first end of the arm relative to the mount in a rotatable direction about the second axis of the hinge.

22. A pivot-arm assembly for attaching an ear cup to a mounting feature of a helmet, the pivot-arm assembly comprising:
-
an ear cup; and a mount configured to releasably couple to a mounting feature on the helmet; an arm having a first portion coupled to the ear cup, the arm having a second portion moveably coupled to the first portion to adjust a length of the arm; a hinge having a first part rotatable about a first axis and second part rotatable about a second axis, the first axis being generally perpendicular to the second axis, the first part of the hinge being coupled to the mount and the second part of the hinge being coupled to the second portion such that the first portion of the arm is rotatable relative to the mount about the first axis and the first portion of the arm is rotatable relative to the mount about the second axis, the second part of the hinge having a torsion spring coupled to the first portion of the arm and configured to spring bias the first portion of the arm relative to the mount in a rotatable direction about the second axis of the hinge, the second part of the hinge having a lock configured to releasably retain the first portion of the arm in a predetermined angular position relative to the second axis, the second part of the hinge having a release configured to selectively release the lock. - View Dependent Claims (23)
