Abstract
A helmet attachment device includes an attachment device for a helmet, the attachment device comprising a clamp including means forming a “u” shaped lower section for receiving a portion of the helmet, wherein the clamp includes an exterior; and a cam pivotally mounted to the clamp for movement between a released and clamped position to respectively disengage and engage the attachment device to the helmet.
Claims11
An attachment device for a helmet, the attachment device comprising:
- a clamp comprising a lower section for receiving a portion of the helmet;
- and
- a cam comprising a cam axis mounted to a pivot axis of the clamp for movement between a released and clamped position to respectively disengage and engage the attachment device to the helmet, wherein the cam axis pivots relative to the pivot axis,
- wherein the cam axis is movable relative to a portion of the cam to adjust a distance between the portion of the cam and the pivot axis of the clamp.

An attachment device for a helmet, the attachment device comprising:
- a clamp comprising a lower section for receiving a portion of the helmet;
- and
- a cam comprising an insert having a cam axis mounted to a first pivot axis of the clamp for movement between a released and clamped position to respectively disengage and engage the attachment device to the helmet, wherein the cam axis pivots relative to the first pivot axis,
- wherein the insert of the cam is movable relative to the first pivot axis of the clamp to adjust a distance between a portion of the cam and the first pivot axis of the clamp.

An attachment device for a helmet, the attachment device comprising:
- a clamp comprising a “u” shaped lower section for receiving a portion of the helmet;
- a first cam;
- and
- a second cam,
- wherein the clamp has a pivot axis configured to selectively couple to the first cam and the second cam for movement between a released and clamped position to respectively disengage and engage the attachment device to the helmet,
- wherein the first cam comprises a first cam axis and a first contact surface for contacting the helmet in the clamped position;
- and
- wherein the second cam comprises a second cam axis and a second contact surface for contacting the helmet in the clamped position;
- and
- wherein a distance between the first cam axis and the first contact surface of the first cam is greater than a distance between the second cam axis and the second contact surface of the second cam for adjusting a distance between the cam and an opposite wall of the “u” shaped lower section when selectively coupled.
