1. A hinge system of a hood of a vehicle, comprising:
a hinge which is arranged between the hood and a counter-element of the vehicle, wherein the hinge is configured both for opening the hood and for lifting the hood in a closed state; and
a lifting-piston actuator for introducing a lifting movement of the hood, wherein
the lifting-piston actuator has a piston element which is connectable to the hinge and/or to the hood in a form-fitting connection, in order to limit a freedom of movement of the hood, wherein
the hinge has a strap element with a holding region for the form-fitting connection to the piston element,
the holding region is movable by the hinge in a piston displacement of the piston element,
the holding region is a region of a through-opening in the strap element,
the through-opening comprises a through-region with a larger cross section than the holding region, and
the piston element is passable through the strap element at the through-region and not passable through the strap element at the holding region.
