Perhaps you could borrow the term "proper frame" from Sp. Relativity.
As I understand the term, an object's/observer's "proper frame" is the
frame in which it/he is at rest..

The term "rest frame" seems to be quite commonly used, at least as
frequently as "proper frame".

Einstein himself, in composing and explaining the relativity laws, did
not use the term "frame". His terminology is usually translated to
"reference-body" or "body of reference". Where we would now say
"inertial frame", Einstein used the term "Galilean reference-body".
Reading his SR and GR, it seems that he envisioned each reference frame
specifically associated with a particular object.
