Hinge system of a hood of a vehicle

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 in a lifting direction, wherein the hinge comprises:
• a hinge upper part with a main link and a hood part;
• two links which are each attached rotatably to the main link and to the counter-element of the vehicle, in order to produce a four-bar mechanism,
• wherein the hood part is configured for fastening to the hood,
• wherein the hood part is fastened to the main link so as to be rotatable at a bearing point and is connected to the main link in a non-rotatable manner by a fixing element, and
• wherein the fixing element is releasable by the lifting-piston actuator, in order to achieve torsion between the hood part and the main link.

A vehicle, comprising:

• a hood;
• and
• a hinge system 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,
• 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,
• the piston element is passable through the strap element at the through-region and not passable through the strap element at the holding region,
• wherein the hood is lifted by the hinge system to a predefined protection height, and
• during the lifting action, an overswing is limited to maximum of 25% above the predefined protection height.
