Eyeglass earstem with enhanced performance
First Claim
1. An earstem assembly comprising:
- a flexible suspension component extending posteriorly from an eyeglass frame, the suspension component having an anterior end and a posterior end; and
a rigid elongate body having an anterior end and a posterior end, the anterior end of the rigid elongate body being pivotally coupled to the flexible suspension component, the rigid elongate body and the suspension component being attached to each other at a point posterior to the anterior ends of the rigid elongate body and the suspension component, the rigid elongate body being operative to rotate relative to the eyeglass frame;
wherein the attachment between the rigid elongate body and the flexible suspension component causes deflection of the flexible suspension component upon rotation of the rigid elongate body relative to the frame.

Abstract
An earstem for an eyeglass is provided that can exhibit a dampening effect as the earstem is over-rotated or deflected from a deployed position to a deflected position. In some embodiments, a suspension component of the earstem can be operative to pivot relative to the frame until reaching a deployed position. The rigid elongate body can be operative to pivot relative to the frame beyond the deployed position. In this regard, the suspension component can be attached to the rigid elongate body along a posterior portion of the suspension component such that pivoting of the rigid elongate body beyond the deployed position causes deflection of the suspension component to dampen further pivoting of the rigid elongate body.

- 9. An earstem assembly comprising a flexible elongate body extending rearwardly from a frame and a rigid elongate body pivotally coupled to an anterior portion of the flexible elongate body to define a first pivot point, the rigid elongate body also being coupled to a posterior portion of the flexible elongate body, wherein the rigid elongate body can be rotated about the first pivot point to move to a deflected position.

15. An eyeglass comprising:
-
a frame; a pair of suspension components extending rearwardly from the frame; and a pair of rigid elongate bodies being pivotally coupled to respective suspension components along an anterior portion of each suspension component to define first pivot points, the pair of rigid elongate bodies also being coupled to the respective suspension components along a posterior portion of each suspension component to define second contact points such that pivoting of the rigid elongate body causes deflection of the suspension components to dampen further pivoting of the rigid elongate bodies. - View Dependent Claims (16, 17, 18, 19, 20)
