US Patent 7503611 Vehicle with a tailgate

A vehicle includes a body and a tailgate coupled to the body by a hinge. The tailgate is moveable between a closed position and an open position. The vehicle also includes two cylinders for exerting a force on the tailgate with respect to the body. One of the cylinders is actuated by a drive device, and the lever arm of the cylinder actuated by the drive device with respect to the hinge is greater than the lever arm of the other cylinder with respect to the hinge in the closed position of the tailgate. The cylinder actuated by the drive device can develop a greater torque for opening the tailgate, facilitating the opening of the tailgate by a user since the cylinder actuated by the drive device allows for the movement of the tailgate.
