Abstract
An eyewear temple arm apparatus for an eyewear device including an elongated body member having a proximal end portion configured to mount to the eyewear device. The temple arm apparatus includes a functional element, an elongated flexible tether; and a guide base. The base is movably mounted to the elongated body member for movement thereof along a fixed path in a direction generally longitudinally therealong between a first position and a second position. In the first position, the guide base is positioned proximate to a proximal portion of the body member, while in the second position, it is oriented proximate to a distal portion thereof. One end of the tether is mounted to the guide portion and an opposite end thereof is mounted to the functional element such that when guide base is moved between the first and second positions, the functional element is moved between a parked condition, parked relative to the body member, and an operational condition, positioning the functional element sufficiently away from the body member to enable operation thereof.
