Abstract The rotation of a first element (3), for example an arm carrying a lighting unit, with respect to a second element (2), about an axis (12), is limited in both directions, with an angular travel which can exceed 360 DEG, by an elastic element (13) comprising two coils wound in the same direction, each cooperating with a mobile stop piece integral in rotation with the first element (14, 15), the central part of the spring (13) cooperating with a fixed stop piece (16) integral with the second element (2). The present invention is especially the same with the medical equipment comprising articulated system.
