Oculus Rift attach to back of static mesh with (kind of a) springarm

Hey,
my team and I’ve been looking for a solution of the problem posted in the headline. We’re trying to attach the Camera to a spring arm which should be fixed in the back of the static mesh and follow any movement. The Camera itself should follow the rotation and the location of the spring arm (and therefore loc. and rot. of the static mesh) but you should still be able to look around freely.
So far we achieved to follow the static mesh in the world location without “sticking” to its back so we actually ended up watching our pawn flying out of sight while flying behind it in a fixed position.
We’re already desperate, please help!
Best regards
