Very neat (short) show on how school bus seats are made and tested on the science channel, 284 on DirecTv.
Highlights:
Seat fabric has fire resistant vinyl made from Kevlar.
Bolts holding belts on can take up to 150,000 lbs of force.
Seat back has foam padding with 4 types of foam.
35 MPH impact into the back of the seat testing.
6 rams with chains hooked to the seats pull and find that it does not break until it hits 20,000 lbs of pressure.
