Abstract: An abutment mechanism for limiting the flapping of the blades of a rotor (1). High abutment members (6) can be moved into an engagement position by return means (13) exerting an intrinsic return force (R), and into a disengagement position by a flyweight (10) exerting a centrifugal force (C) under the effect of the rotor (1) rotating. At least one magnetic type bistable latch (15) is in selective engagement with the high abutment members (6). When the rotor (1) is stationary and while it is starting to rotate, an engagement latch (15) engages with the high abutment member (6) to prevent it passing from the engagement position towards the disengagement position. At a predetermined centrifugal force threshold, the engagement of the engagement latch (15) with the high abutment member (6) is broken, and the high abutment member (6) quickly passes into the disengagement position.
