Headgear support device having front-back adjustment

A headgear support device for supporting a face shield comprising:

• a headband having an elongated slot;
• and
• a pivot element affixed to the face shield, wherein the pivot element is slidably located within the slot to enable translational movement of the face shield and wherein the pivot element is also rotatable within the slot to enable rotational movement of the face shield;
• and a pivot link;
• wherein
• the pivot link has a hole therein through which the pivot element extends to locate the pivot link on the pivot element and having upper and lower guide elements which fit over and accommodate top and bottom portions of a perimeter of the slot such that the pivot link is constrained for sliding movement relative to the slot with the pivot element, a location peg being formed on the pivot link;
• and further including
• a pivot stop which, in use, is attached to the face shield, the pivot stop having an hole therein through which the pivot element extends to rotatable mount the pivots top on the pivot element, and further having upper and lower recesses into which the location peg is accommodated during rotation of the pivot stop on the pivot element so as to hold the pivot stop in first and second rotational positions on the pivot element corresponding, in use, to raised and lowered positions of the face shield.
