Abstract:
1. A control system intended for the choice and selection of functions in a vehicle, the system comprising: a case; a lever configured to extend along a main axis from a first end to a second end, said first end located inside the case, and mounted to pivot about a pivot axis, said second end located outside the case and provided with an actuation knob, the lever also being able to turn about the main axis; an elastic return device configured to cooperate with the lever so that, following a pivoting and releasing of the lever, the lever returns to a neutral position where the main axis coincides with a neutral axis, wherein said elastic return device comprises an elastic means that includes an active zone configured to cooperate with an action surface attached to the lever, wherein the action surface comprises a surface in the form of a truncated cone of revolution aligned with the main axis, the cone being so that in response to pivoting of the lever, the active zone is displaced along a generatrix of the cone towards a vertex of the cone, the elastic means being more biased than in the neutral position; and a device limiting in the neutral position the possibility of rotation of the lever about the main axis, this then coinciding with the neutral axis, wherein said device includes a first toothed surface attached to the lever and a second toothed surface attached to the case, the toothed surfaces being distant one from the other in the neutral position, the lever then being able to turn about the neutral axis, and the toothed surfaces engaging with each other on a pivoting of the lever, the pivoted lever not being able to turn about the main axis.
