Pedal mechanism collision safety.

Pedal mechanism collision safety for a vehicle, pivoting said pedal (1) about an axis of rotation (2) connected to a support part (3) and mechanism comprising means security displacing the axis of rotation ( 2) towards the driver in a frontal collision due to the action of a part (4) of substantially undeformable vehicle. Means displacing the axis of rotation (2) comprise a lever (5) and a slide (6), such that, in a frontal collision, the portion (4) substantially indeformable acts on the lever (5) , said lever (5) acts on the slide (6) and said slide (6) pushes the rotational axis (2) of the pedal (1), causing said rotation axis (2) detaches from the support part (3).
