- console position in which the plane of the rim 12 is then inclined with respect to the direction of the central part 16, in particular so that a user can for example place a computer on the rim 12.
- the possibility of changing the angular position is not necessarily limited to a pivoting of the whole of the rim 12, but can also concern only a portion of the rim 12 - for example only a half of the rim, such a rim portion constituting a mobile structure of the rim within the meaning of the invention.
- the primary pivot axis A1 of the rim 12 is oriented axially from the rear to the front.
- the steering wheel 10 here comprises a lateral module M for driving and locking the rim 12.
- the lateral module M is here arranged adjacent to rear branch 14 of steering wheel 10.

- FIG. 3 represents:
- a pivoting drive pinion 26 of the rim 12 which permanently meshes with the input pinion 24 (By way of non-limiting example, the drive pinion 26 is mounted for rotation around the primary axis A1 pivoting of the rim 12);
- a locking rocker 22 comprising a proximal portion shaped as a locking pinion 28 which is rotatably mounted around a locking axis A3 and which meshes permanently with the input pinion 24, and comprising a distal arm 30 which extends radially from the blocking pinion 28 and whose free end section 32 is shaped as a convex blocking surface, substantially in the arc of a cylinder.

- a fixed axial abutment pin 48 is arranged between the two reinforcement plates 50 and it is capable of cooperating with the abutment section 42 opposite the peripheral edge of the radial plate 36 of the hub 34.
- the angular driving position of the rim 12, around its primary pivot axis A1 is determined by the angular abutment of the abutment section 42 of the peripheral edge 37 of the radial plate 36 of the hub 34 in contact against the axial pin fixed stop 48.
- the blocking is ensured by the complementary locking surfaces 32 and 40 which are braced against each other by a clamping effect, thus ensuring locking without angular play of the rim 12 of the steering wheel, including understood after having taken up the clearances between the teeth of the various sprockets.

- control branch 22i comprises a circumferential cam follower element 52 which cooperates with an "L" shaped cam profile section 54 which is carried and which is driven in rotation by rim 27 of the drive pinion 26 .
- the cam follower 52 is permanently biased elastically against the L-shaped cam profile 54 by a blocking spring 56 which permanently biases the blocking rocker 22 in rotation in the clockwise direction in view of Figs 5 and 6A.
- the blocking branch 22s comprises a circumferential blocking nose 60 which is adapted to cooperate with a blocking section 62 of the peripheral edge 37 of the radial plate 36 of the hub 34 which is here in two consecutive parts 62-1 and 62-2, substantially at right angles.
- the first part of the angular travel of the input pinion 24 along F1 immediately causes the rotation of the drive pinion 26 and of the cam profile 54.
- the cam follower element 52 then leaves the radially outermost portion 54-1 of the cam profile 54 and descends along the inclined and radially innermost portion 54-2 of the cam profile 54. Under the action of the locking spring 56, this will cause the pivoting according to the arrow F1 of the locking fork 22 and release of locking spout 60.
- the input pinion 24 drives the drive pinion 26 and its axial drive finger 44 which then moves inside the notch 38, and this against the elastic return force exerted by the spring 46.
