A deceleration device comprises a cylindrical container (14) housing at least one friction disc (16) against at least an internal wall of the cylindrical container (14), and a movable cursor (18), actuated by an external element, for the actuation of the friction disc (16), the friction disc (16) being bound to the cylindrical container (14) through constraint means which permit a roto-translational motion in order to acquire a further sliding contact surface in addition to the internal wall of the cylindrical container (14) at the end of the initial translation phase of the cursor (18) in which the friction disc (16) is subjected to a mainly or completely translational motion. |
