In the first episode of the animated Star Trek series, Beyond the Farthest Star, an away-team investigates an alien ship using "life support belts," which appear to protect the wearer with a force-field type of space suit. They are also mentioned by Uhura later in the same episode, when life support is lost on lower decks, and crew members are forced to use the life support belts.
Have these "life support belts" ever been or mentioned used elsewhere in the Star Trek universe?
I remember clear examples of space walks taking place on other Trek series, so the belts clearly never replaced space suits. The scene to modify the deflector dish in Star Trek: First Contact comes to mind as an example of physical suits being used.
