Narrative:

A student and I had just flown in to ZZZ on a cross country flight. We landed and observed no other traffic in the pattern or on the ground; so we sat on the runway to allow time for my student to readjust his kneeboard for the next leg of the flight. When the student was ready (no more than 30sec after touchdown) he [placed] the helicopter into a hover. As my student was checking his gauges for takeoff we heard over CTAF '...taking the runway one six for takeoff; departure to the north.' I then asked my student to perform a right pedal turn to look behind us down the runway to make sure there was not an aircraft 'barreling down on us'. My student saw an aircraft rolling toward us and said 'uuuh; he is'. I then turned my head; saw the aircraft approaching us; took the controls and rapidly moved us into the grass area to the right of [the] runway. I made a radio call saying that I was on the active runway; no response from the airplane. As the aircraft passed us; I called out his tail number 'aircraft Y' to which someone replied 'you're on the grass!' the pilot made no other radio calls. Estimated distance of closest intercept was 75 ft.
