Abstract

Head-worn apparatus to which an optical device is adjustably coupled is disclosed. The apparatus comprises a headband, a support bow for the optical device rotatably coupled to the headband and a locking mechanism for automatically locking the bow in a viewing position of the optical device and in a rest position of the optical device while permitting the bow to be swivelled between the two positions. An articulated coupling adjustably connects the optical device to the central region of the bow. The locking mechanism always locks the bow in the same viewing position of the optical device so that once the articulated coupling has been adjusted with the optical device in its viewing position, the bow and with it the optical device can be swivelled back and forth between the rest and use positions without having to readjust the optical device. This arrangement enables a user to position an optical device in front of his or her eyes for use and move it out of the way without either taking the apparatus off his or her head or readjusting the optical unit.
