Abstract
A helmet includes a shell configured to extend over ears of a user with integrated acoustic ear cups or ear phones that can be positioned and pressure adjusted while the helmet is in use. An adjustment mechanism connected to each ear cup includes a portion extending through an aperture in the helmet shell to facilitate movement of the ear cup using the portion extending through the shell. The adjustment mechanism may be used to move the ear cups between a retracted position to facilitate donning and removal of the helmet and a user adjustable deployed position with user adjustable side pressure to facilitate sealing and comfort for passive or active noise reduction (ANR).

A helmet, comprising:
- a shell configured to extend over ears of a user and having an aperture;
- an ear cup disposed within the shell;
- and
- an adjustment mechanism connected to the ear cup, the adjustment mechanism having a base fixed to an interior of the shell and a portion extending through the aperture of the shell to facilitate movement of the ear cup using the portion extending through the shell.
A helmet having a shell configured to cover ears of a user when worn and having an elongated slot on at least one side of the shell, the helmet including an adjustment mechanism comprising:
- an arch adapted to be fixedly secured to an interior portion of the shell;
- a positioner having first and second arms connected at a proximate end and spaced apart from one another at a distal end, each arm including an aperture adapted to receive an ear cup mounting post;
- and
- a clamping device operatively associated with the positioner and having a portion extending through the elongated slot of the shell to move the positioner within the arch and to selectively secure the positioner in a position along the elongated slot of the shell.
A helmet having a shell configured to receive and substantially surround integrated circumaural ear cups, the helmet comprising an adjustment mechanism for each ear cup having a portion adapted to couple to an associated ear cup and a portion extending through the shell to move the associated ear cup between a retracted position and an engaged position using the portion extending through the shell.
