Hinged cargo liner

A hinged cargo liner adapted to assume unfolded and folded configurations, the cargo liner comprising:

• a floor panel adapted to be placed on a floor of a cargo area of a vehicle, the floor panel having a front margin, a top surface and a bottom surface for placement on the floor of the cargo liner, the floor panel having a substantially uniform floor panel thickness between the top surface and the bottom surface;
• a first pleat having a rear margin and a front margin, a top surface of the first pleat extending from the rear margin of the first pleat to the front margin of the first pleat, an opposed bottom surface of the first pleat extending from the rear margin of the first pleat to the front margin of the first pleat, the first pleat having a substantially uniform first pleat thickness between the top surface of the first pleat and the bottom surface of the first pleat;
• a second pleat having a rear margin and a front margin, a top surface of the second pleat extending from the rear margin of the second pleat to the front margin of the second pleat, a bottom surface of the second pleat extending from the rear margin of the second pleat to the front margin of the second pleat, the second pleat having a substantially uniform second pleat thickness between the top surface of the second pleat and the bottom surface of the second pleat,
• a seat back panel having a rear margin and a front margin, a top surface of the seat back panel extending from the rear margin of the seat back panel to the front margin of the seat back panel, a bottom surface of the seat back panel extending from the rear margin of the seat back panel to the front margin of the seat back panel, the seat back panel having a substantially uniform seat back panel thickness between the top surface of the seat back panel and the bottom surface of the seat back panel;
• a first hinge joining the front margin of the floor panel the rear margin of the first pleat, the first hinge having an upper surface forming a continuous upwardly concave arc between the front margin of the floor panel and the rear margin of the first pleat, the first hinge having a lower surface which is substantially continuous between the lower surface of the floor panel and the lower surface of the first pleat, a thickness of the first hinge varying as a function of distance from the front margin of the floor panel and having a single minimum smaller than the floor panel thickness and the first pleat thickness;
• a second hinge joining the front margin of the first pleat to the rear margin of the second pleat, the second hinge having an upper surface which is substantially continuous between the upper surface of the first pleat and the upper surface of the second pleat, the second hinge having a lower surface forming a continuous downwardly concave arc between the lower surface of the first pleat and the lower surface of the second pleat, a thickness of the second hinge varying as a function of distance from the front margin of the first pleat and having a single minimum that is smaller than the first pleat thickness and the second pleat thickness;
• and
• a third hinge joining the front margin of the second pleat to the rear margin of the seat back panel, the first hinge having an upper surface forming a continuous upwardly concave arc between the front margin of the second pleat to the rear margin of the seat back panel, the third hinge having a lower surface which is substantially continuous between the lower surface of the second pleat and the lower surface of the seat back panel, a thickness of the third hinge varying as a function of distance from the front margin of the second pleat and having a single minimum smaller than the second pleat thickness and the seat back panel thickness.
