Device for displacement of a movable blocking element

The invention relates to a device for the displacement of a movable blocking element (10) of a functionally essential component (50), in particular a steering column (50) of a motor vehicle, with a drive (20), which communicates with the blocking element (10) so mechanically operatively connected that the locking element (10) between a locking position (1) and an unlocking position (2) is movable, in the locking position (1) engages the locking element (10) in the functionally essential component (50) and in the unlocked position (2) the locking element ( 10) detached from the functionally essential component (50). According to the invention it is provided that the locking element (10) on an axle (11) is rotatably mounted, to perform a movement between the locking position (1) and the unlocking position (2), a safety guide (30) is provided, which (at a deformity 4) of the component (50) causes the locking element (10) can be brought into an intermediate position (3) (between the locking position 1) and the unlocking position (2), wherein the safety guide (30) is designed such that during movement between the locked position (1) and the unlocking position (2) the locking element (10) (11) pivots only about the axis, wherein the axis (11) retains its position in the safety guide (30), and in case of misalignment (4) of the component (50) during the movement from the locking position (1) to the intermediate position (3) the blocking element (10) provided around the axis (11) is pivotable to a contact of the blocking element ( 10) is present with the component (50) and then the axis (11) with the locking element (10) along the safety guide (30) is translationally movable in a direction that is opposite (the component 50).
