I saw this idea the other day when looking for something else, so I did not keep a record of it.
It was in a pdf paper on improving sailplane safety and crash survivability, but may also be useful for power planes. Maybe someone else will recognize the idea and post a link to the pdf?
The seat they described was supported on 4 linkages, two on each side attached to the seat bottom, and to the cockpit wall. The seat rests on a structure made of aluminum honeycomb material, although I think foam could also be used.
How it works is that during a hard landing, the aluminum honeycomb crushes absorbing most of the forces. At the same time the seat swings down and forward on the linkages.
The seat back angle and lumbar support also play an important role.
