DEVICE FORMING A STEP OF A MOTOR VEHICLE

The invention relates to a step device comprising a body element (1) of a motor vehicle, a cavity (2) formed in the body element (1) delimited by a lower wall (3) forming a bearing surface for a front part of a user's foot (4). The device comprises a movable platform (8) articulated on a structural element (9, 11, 12) of the vehicle, between a deployed position below the lower wall (3) in the direction of the body element (1), and a retracted position opposite the body element (1), the movement of the movable platform (8) towards the retracted position being carried out under the constraint of the body element (1) undergoing deformation resulting from an impact.
