Now consider a heavy five-inch wide nylon webbed belt. As I stated in a previous article, the belt may have been up against a metal edge on the seat. They claim that the belt was fastened to the floor of the racecar. I erred previously thinking the belt was attached to the roll cage structure. But, in order to break it, the body would have to be strong enough to exert thousands of pounds of pressure, and it just isn't logical that a mass of flesh and bones would not break apart before breaking a five inch woven nylon belt.
Truckers use four-inch nylon straps to strap down loads weighing thousands of pounds.
I have seen trailers that have flipped over in accidents, and the belts did not break, they held the load intact to the trailer. It seems logical that if anything were to come apart, it would be the stitching where the belt is attached to the buckles. It was reported that the stitching did not come apart. Another item that I find interesting, is the statement made by firefighter Tommy Probst concerning firefighter Jason Brown's attempt to cut Dale's woven nylon helmet strap with shears. It would not cut.
