<p>The invention relates to an adjustable helmet (10) having a front shell (12) and a back shell (14) that are movably secured to one another and that comprise engaging members (25) that may be held together by a locking mechanism (30) comprising a cam (32) that pivots about an axis extending in a direction that is substantially parallel to a side portion of the helmet (10). The locking mechanism (30) of the present invention has the advantage of exerting a compressive force on a substantial portion of the engaging members (25) thereby providing a more solid engagement. The locking mechanism (30) also has the advantage of being easily replaceable by a conventional mounting screw assembly (52, 55). The helmet (10) of the present invention is particularly well suited for use in hockey or other like sports.</p> |
