Abstract
A mechanical device for controlling changeover between two modes of relative displacement between two objects comprising: two assemblies capable of moving in guided relative translation, one assembly being fixed, and the other assembly moving, the device further comprising: resilient controller interposed between the two assemblies with a controlled clearance to define the mode of relative displacement; and an inertial mass associated with one of the assemblies and adapted to act selectively on the controller as a function of the time profile of moving assembly displacement in order to modify the clearance and the mode of relative displacement.
