Steering column

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;
• wherein, between the base (20) and the upper section (50), an intermediate section (30) can be interposed, the upper section (50) is slidably connected to the intermediate section (30) defining a degree of translational freedom of the upper section (50) relative to the base (20);
• wherein, between the upper section (50) and the intermediate section (30) a frictional locking assembly (54, 55) is interposed, equipped with a control member (53, 56) selectively operable between a closed position, in which it stops the sliding of the upper section (50) with respect to the intermediate section (30), and an open position, in which it releases the sliding of the upper section (50) relative to the intermediate section (30);
• wherein the actuation lever (60) can be connected to the control member (53, 56) for the actuation of the same selectively between the closed position and the open position, respectively in the locked position of the actuation lever (60) and in a first position of the two unlocked positions of the same;
• and wherein the actuation lever (60) is rotatably connected to the upper section (50) with respect to a first axis of oscillation (B) and comprise a cam (61) with an eccentric profile relative to the first axis of oscillation (B) and adapted to actuate the control member (53, 56) selectively between the closed position and the open position as a result of an oscillation of the cam (61) with respect to the first axis of oscillation (B) of a given angle of oscillation.
