Flexible folding cover

A tonneau cover system for a cargo box of a pickup truck, said pickup truck having a passenger cabin, said tonneau cover system comprising:

• a plurality of tonneau sections being positionable generally over the cargo box of the pickup truck, said plurality of tonneau sections having at least a first tonneau section, a second tonneau section, a third tonneau section, and a fourth tonneau section, said plurality of tonneau sections being generally coplanar in an extended position;
• a first hinge system hingedly coupling said first tonneau section and said second tonneau section to permit pivotal stacked nesting of said first tonneau section relative to said second tonneau section;
• a second hinge system hingedly coupling said second tonneau section to said third tonneau section to permit pivotal stacked nesting of the combination of said first tonneau section and said second tonneau section relative to said third tonneau section;
• a third hinge system hingedly coupling said third tonneau section to said fourth tonneau section to permit pivotal movement of the combination of said first tonneau section, said second tonneau section, and said third tonneau section relative to said fourth tonneau section into a retracted, stacked, and rotated upward position;
• and
• a standoff device operably coupled to said third hinge system, said standoff device operable to at least partially retain the combination of said first tonneau section, said second tonneau section, and said third tonneau section in said retracted, stacked, and rotated upward position.
