look at catt tape player doors that opened slowly for ideas..
they have to hinges like your helmet/mask and where spring loaded, with a gear/clutch that was small/cheap and slowed the door movement..

That would work if you only need to open it remotely, and you can push it closed. If you want it to open and close remotely, then it needs real actuation, not just a release and spring.
