Abstract
Abstract The support is for viewing gear used aboard a vehicle and comprises means enabling its anchoring at a point situated above the head of the operator of the viewing gear, and an arm balanced by counterweights and bearing the viewing gear. The arm is mounted to pivot around an axis, parallel to the optical axis of the viewing gear and borne by a bow-shaped element. The support has between the upper anchoring means and the bow-shaped element a cardan joint enabling angular variations of the pivot about the latter. The pivot bears a rotary element on which are hinged, by one of their ends, around horizontal axes, two arms situated in a same vertical plane and between which a helicoidal spring is arranged. The arms bear at their free end around horizontal axes parallel to the preceding ones respectively the upper end of two vertical bars, on the other end of which are pivoted the ends of the bow element around horizontal axes situated in extension of one another and at right angles to the pivoting axes of the upper ends of the bars, the upper and lower pivots of each of the two bars being such that they enable angular variations.
