A head stabilizing system is provided. The head stabilizing system is intend ed to minimize loads on the head and the neck, some of which may be injurious o r even fatal, by generating a reaction force that substantially opposes a forc e acting on the head and generated by rapid deceleration of a vehicle or a cra sh impact. The head stabilizing system includes a helmet, a connection structur e, and at least one resisting member. The resisting member generates a reaction force that opposes the crash impact force, yielding a reduced net force on t he head. This reaction force can be generated as a function of position, veloci ty or acceleration. The resisting member may include a tether, a dashpot, or a dashpot containing a controllable rheological fluid. The viscosity of the controllable rheological fluid can be automatically adjusted in response to changes in status of a vehicle or it's occupant.
