Also es scheint doch zu stimmen das es wirklich "Gravschirme" gibt.
Ich habe mal die Textstelle rausgesucht in der so ein Ding beschrieben wird.
Das ganz stammt aus dem Buch "The Guns of Tanith" aus der Gaunt's Ghosts Reihe und ich habe leider nur den englischen Originaltext. Es steht übrigens aus Seite 193, falls es jemand nachschlagen will/kann.
"Babbist opened the crate and lifted something out for them all to see. It was a compact but heavy metal backpack with a fearsome harness that included thigh loops, and a hinged arm with a moulded handgrip on the left side. The backpack sprouted two blunt, anter-like horns from the shoulders that ended in fist-sized metal balls. It was painted matt-green.
'What we have here, friends and neighbours', ssaid Babbist, patting the old, worn unit, 'is a classic type five infantry jump pack. Accept no imitations. Formal spec, for those that need it, is Type Five Icarus-Pattern Personal Descent Unit with dual M12 gravity nullers and a variable-vent compressor fan for attitude control. Which, I gather many of you need.'"
