<p>A device for limiting the rotational range of a swiveling arm, comprising a discoidal reaction element (1) adapted to be connected to an element of said swiveling arm so as to integrally turn with said swiveling arm, and further comprising at least a limiting element (2) adapted to cooperate with at least an abutting fixed element (6), said limiting element (2) being reversibly constrainable in any circumferential position along the external perimeter of said discoidal reaction element (1), in order to determine a limiting angle of the rotational range of said swiveling arm, wherein said discoidal reaction element (1) comprises an upper face and a lower face, and wherein said limiting element (2) comprises a reversible junction (4) adapted to clamp said upper face and said lower face in a same circumferential position.</p> |
