Patent ID: 7845439

Claim:
A device for reversing a steering movement of a steering wheel shaft of a vehicle, having: a switching element movable between two switching positions to activate or deactivate the reversal of the steering movement; a mechanical actuating device comprising a shaft and a slide configured to actuate said switching element, said shaft extending along an axial direction and being rotatable in opposite rotational directions about said axis, and said slide being movable along said axis in an axial direction of said shaft which is a function of a rotational direction of said shaft to transfer said switching element between said switching positions; a first toothing system having a first pitch; and a second toothing system having a second pitch, the first and second pitches being different; the first and second toothing systems being driven with a rotational speed difference relative to one another and being engagable with said slide to move said slide relative to said shaft as a function of the rotational direction of said shaft and to transfer said slide between two slide positions which correspond to said two switching positions of said switching element, wherein said slide is in engagement with said first and second toothing systems during the movement of said slide along said shaft, said slide is disengaged from at least one of said first and second toothing systems in each of said two slide positions.
