Abstract
A head worn apparatus having a pair of rearwardly disposed elongated support arm assemblies having movable portions which are positionally adjustable to provide increased wearer comfort attached to a head-worn device such as a visor or eyeglasses. The support arm assemblies each include a an articulating segment and/or head gripping region pivotally coupled to the head-worn apparatus. The articulating segment include means for providing a constant inward compressive force by means of increased resistance for rotating articulating segments outwardly, thereby securing the head-worn device onto a wearer's head.

An articulating head worn support apparatus, comprising:
- a first and a second support arm assembly, at least one said assembly including an articulating member coupled to an articulating hinge assembly, said articulating hinge assembly comprising
- a first sleeve,
- a second sleeve,
- a plunger disposed within said first and second sleeves, and
- a lock and release mechanism configured for adjusting the position of said first sleeve in relation to said second sleeve in a ratcheting manner;
- said lock and release mechanism comprising
- a plurality of serrations longitudinally disposed on said plunger,
- a plurality of longitudinally disposed serrations within said first sleeve,
- said serrations within said first sleeve configured to engage said serrations on said plunger,
- an annular spring for biasing said serrations on said plunger against said serrations within said first sleeve, and
