Abstract
A twisted strap transfers loads generated by an aircraft passenger floor from the floor to an aircraft fuselage. The twisted strap may be formed of carbon fiber reinforced plastic, fiberglass reinforced plastic, or metal, such as aluminum, stainless steel, or titanium alloy. The twisted strap has first and second ends configured to be twisted between 40 to 120 degrees relative to the other whenever connected to a seat track and a forward-aft extending fuselage stiffener, respectively. In at least one form, the twisted strap has a length ranging from 15 to 30 inches, a width of 1 to 2 inches, and thickness of 0.1 to 0.5 inch. Each end incorporates apertures for accommodating separate connectors spaced at least four-to six diameters apart along the length of the twisted strap, and the twisted strap is configured to accommodate minimums of 9 G's of force in tension and 1.5 G's in compression.
