Claims17
A method of operating a tonneau cover, the tonneau cover configured for placement above a cargo area of a vehicle, the cargo area having a plurality of side walls, the method comprising:
- a first pivoting step, where a first moveable panel of the tonneau cover is moved on top of a second moveable panel of the tonneau cover about a first hinge, and then a second pivoting step where both of the first moveable panel and the second moveable panel are moved together on top of a third panel of the tonneau cover about a second hinge;
- wherein during the second pivoting step, a torsion element that is arranged between the second moveable panel and the third moveable panel is configured to apply an assisting force or torque onto the second moveable panel to at least partially offset a weight of at least both of the first moveable panel and the second moveable panel as the first moveable panel and the second moveable panel are together moved on top of the third panel.
A method of operating a tonneau cover, the tonneau cover configured for placement above a cargo area of a vehicle, the cargo area having a plurality of side walls, a front wall that is adjacent to a passenger area of a vehicle, and an opposing tailgate, the method comprising:
- i) a first moving step where a first movable panel of the tonneau cover is moved in an upwardly direction away from a top end of the tailgate and onto a second movable panel of the tonneau cover, then ii) a second moving step where the first movable panel and the second movable panel are together moved onto a third movable panel of the tonneau cover, and then iii) a third moving step where the first movable panel, the second movable panel, and the third movable panel are together moved onto a fourth panel of the tonneau cover, wherein during the third moving step, a torsion element is configured to apply an assisting force or torque onto the third moveable panel to at least partially offset a weight of at least the first movable panel, the second movable panel, and the third movably panel.
