ABSTRACT:
An eye shield or eyepiece for a viewing device, especially for a day and night vision sighting device for aiming a weapon essentially comprises a headrest and first and second mounting frames. These components form an assembly for mounting on the housing of a viewing device. For the practical manipulation and adaptation of the headrest to the form of the head of the observer, two hinge-like articulations are provided in mutually spaced relationship on the external face of a forehead rest of the headrest. A relatively low pressure force against the inner face of the forehead rest deforms and correspondingly adapts the elastomeric or flexible plastic headrest. In order to actuate, for instance, a laser distance measuring device mounted in the viewing device, the assembly formed by the headrest and first and second mounting frame components is articulated to the housing of the viewing device, and an actuating or switching member mounted on the second mounting frame can be brought into engagement with an enabling switch.
