More likely than not, you will not find a regulation that states the seatbelts need to be replaced. But call and ask a manufacturer; they will know. If the aircraft was truly in an accident, I would replace the belts. In certificated airplanes (and you can watch the front end impact tests of automobiles, too), the belts stretch a lot during impact. If a stretched restraint is reused in the stretched condition, it will not give on initial impact and stop the occupant in a quicker fashion, imparting higher G-loads into the body.
