3. The cover according to claim 1 , wherein the torsion element is attached to one or both of the opposing side walls of the cargo area.
4. The cover according to claim 1 , wherein the torsion element includes end portions that are attached to the single panel.
5. The cover according to claim 1 , wherein the frame comprises a recess into which the torsion element is at least partially received.
6. The cover according to claim 1 , wherein a bracket is attached to the frame, and the torsion element is attached to the bracket.
7. The cover according to claim 1 , wherein the cover comprises a second torsion element that is configured to apply an assisting force or torque onto the single panel to assist the motor and/or the torsion element in moving the single panel.
8. A cover for a vehicle comprising a cargo area, the cargo area has a plurality of walls that include opposing side walls, a front wall that is located adjacent to a passenger cab of the vehicle, and a rear wall or tailgate, the cover comprising:
a single panel;
one or more hinges, brackets, or mechanisms that connect the single panel to the vehicle and/or to provide for the single panel to be moved relative to the cargo area or vehicle between a closed configuration and an open configuration and/or between the open configuration and the closed configuration;
one or more shocks configured to assist with moving the single panel and/or for maintaining a position of the single panel in the open configuration; and
a torsion element that is configured to apply an assisting force or torque onto the single panel during movement of the single panel between the closed configuration and the open configuration and/or between the open configuration and the closed configuration; and
wherein the single panel comprises an outside surface and an opposing inside surface that is configured to face an inside of the cargo area, and the torsion element is connected to the inside surface of the single panel and applies the assisting force or torque onto the inside surface.
9. The cover according to claim 8 , wherein the torsion element is a torsion bar that has a U-shape.
