Front flap hinge for a motor vehicle and motor vehicle comprising a front flap hinge of this type
A front flap hinge for a motor vehicle comprises a hinge upper part and a front flap securing element which can be secured to a front flap of the motor vehicle and is connected to the hinge upper part such that it can swivel about a first pivot axis extending in a transverse direction. The hinge upper part comprises a guide element in which a guide counter element of the front flap securing element is guided in a first crash scenario. The guide counter element can be removed from the guide element in a second crash scenario. The invention also relates to a motor vehicle comprising a front flap hinge of this type.
1 . A front flap hinge for a motor vehicle, comprising:
an upper hinge portion; and,
a front flap securing element which can be secured to a front flap of the motor vehicle and which is connected to the upper hinge portion so as to be able to be pivoted about a first pivot axis which extends in the transverse direction;
wherein the upper hinge portion comprises a guiding element in which a guiding counter-element of the front flap securing element is guided in a first crash instance; and,
wherein the guiding counter-element can be removed from the guiding element in a second crash instance.
2 . The front flap hinge according to claim 1 , wherein:
the guiding counter-element can be removed from the guiding element by displacing the guiding counter-element in the transverse direction; and/or,
by pivoting the guiding counter-element about a second pivot axis which extends in the vertical direction.
3 . The front flap hinge according to claim 1 , wherein the guiding element is a slotted guiding member and the guiding counter-element is a guiding journal which is arranged in the slotted guiding member.
4 . The front flap hinge according to claim 1 , wherein the guiding element is configured to be open in an upper region in the vertical direction, at the rear in the longitudinal direction.
5 . The front flap hinge according to one of claim 1 , wherein the guiding counter-element has such a length and/or such play in the guiding element that the guiding counter-element in the second crash instance can be removed from the guiding element by pivoting about the second pivot axis.
6 . The front flap hinge according to claim 1 , wherein:
the first crash instance is a front-end crash in which in the transverse direction no force acts on the upper hinge portion, or in which a force which acts on the upper hinge portion in the transverse direction is below a defined threshold value; and/or,
the second crash instance is a front-end crash, a side crash or an oblique crash in which at least also in the transverse direction a force acts on the upper hinge portion or in which a force acting on the upper hinge portion in the transverse direction equates to at least a defined threshold value.
7 . The front flap hinge according to claim 1 , wherein the guiding element comprises at the upper end thereof in the vertical direction a recess which extends forward in the longitudinal direction.
8 . The front flap hinge according to claim 1 , comprising a lower hinge portion which can be rigidly fixed to a body of the motor vehicle.
9 . A motor vehicle comprising:
a front flap;
a body; and,
two front flap hinges according to claim 1 , wherein the front flap securing elements are in each case rigidly connected to the front flap.
