ABSTRACT:
A night vision system comprising a helmet (1) having a transparent visor (13 or 15) before or movable to a position before the eye positions (IL, IR) of an observer wearing the helmet and a night vision device (19) having two eye pieces (22L, 22R), one for each eye, supported dependant from the helmet (11) so as to present the eye pieces (22L, 22R) of the device (19) at a short distance before the helmet wearer's eye positions and the visor (13 or 15). The device (19) is supported by means of a four-bar linkage arrangement (A,B,C,D) which constrains the eye pieces (22L, 22R) for rotational movement about the respective eye positions (IL, IR) between different operative positions, and so that the eye pieces (22L, 22R) do not make contact with the visor (13 or 15) during eye piece movement.
