Abstract

Please substitute the new Abstract submitted herewith for the original Abstract: A hinge system of a hood of a vehicle has a hinge which is arranged between the hood and a mating element of the vehicle. The hinge is designed both for opening the hood and for raising the hood when the latter is in the closed state, and includes a lifting-piston actuator for initiating a raising movement of the hood. The lifting-piston actuator has a piston element which can be connected to the hinge and/or the hood in a form-fitting manner in order to limit freedom of movement of the hood.

Claims (49)

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.

2. The hinge system according to claim 1 , wherein

the piston element has a flange-shaped region which is larger in size than the holding region but is smaller in size than the through-region.

3. The hinge system according to claim 1 , further comprising:

an elastic element for application of a force to the piston element in a direction of the holding region and/or for blocking the piston element in the holding region.

4. 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.

5. The hinge system according to claim 4 , 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, and

the strap element is fixedly coupled with the hinge upper part.

6. The hinge system according to claim 4 , 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, and

the strap element is fastened to the main link.

7. The hinge system according to claim 4 , wherein

the fixing element has a predetermined breaking point that can be broken by the lifting-piston actuator and/or a latch device which can be actuated by the lifting-piston actuator.

8. The hinge system according to claim 4 , wherein

the hood part is mounted via a holding element in a slot of the main link, so that a maximum torsion angle is established between the main link and the hood part.

9. 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.

10. The vehicle according to claim 9 , wherein the predefined protection height is approximately 60 mm.
