► here a bladder gHead system by @Banfy
Having your head being moved by an external device feels really like having a helmet with G-Force.
Finally i have just put a bladder behind my head, under the seat cover (red spot) and it give quite good results considering how simple it is to implement ;-)
I can set it either for breaking or accelerating. I prefer the acceleration mode (simulating the helmet being compressed to the seat)

I use springs also but it appears for a different reason. I use torque only motor drivers therefore when a force ceases there is not a return to what would be considered neutral position because positional feedback is not present. In real life your head naturally snaps back to a position that feels natural and that's how my system works too. However there is some inherent resistance to movement in my actuators drivetrains so I use springs to provide just enough counterforce so your head doesn't feel a resistance when righting itself.
