“WEAR YOUR SEATBELT!!!”
That would only help if the pot metal or plastic seats stay bolted down.
I don’t believe I have EVER seen an aircraft seat made of pot metal. Steel and aluminum, yes. Same as the rest of the aircraft.
As for plastic ...
My seat on a UH60 consist of a steel frame and half-inch thick Kevlar composite bucket.
