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 °, 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)
