Abstract: A steering column (10), comprising: a base (20); an upper section (50) connected to the base (20), wherein the upper section (50) is movable relative to the base (20) with respect to at least two degrees of freedom; an actuation lever (60) connected to the upper section (50) and operable between a locked position, in which the actuation lever (60) is in stable equilibrium and constrains both degrees of freedom of the upper section (50) relative to the base (20), and two distinct unlocked positions, each of which respectively releases one of the two degrees of freedom of the upper section (50) relative to the base (20); wherein, in the two unlocked positions, the actuation lever (60) is located in two distinct respective stable equilibrium positions.

Abstract: A steering column (10), comprising: —a base (20); —a lower section (25), hinged to the base (20); —an intermediate section (30), hinged to the lower section (25); —an actuation lever (60) operable between a locked position, in which the actuation lever (60) is in stable equilibrium and constrains the mutual rotation of the lower section (25) relative to the base (20) and the mutual rotation of the intermediate section (30) relative to the lower section (25), and a first unlocked position or a second unlocked position, distinct from each other, in each of which it respectively releases one of the mutual rotation of the lower section (25) relative to the base (20) and the mutual rotation of the intermediate section (30) relative to the lower section (25).
