The invention relates to an arrangement of a front gate on a vehicle, the
arrangement comprising at least one hinge system located at the rear in
the direction of travel, in the form of a four-bar mechanism with a long
arm and a short arm. The hinge system enables the front gate to be
pivoted for standard opening and closing, and to be raised at the rear
thereof in the event of a collision. To this end, the hinge system
comprises an energy accumulator that actuates a displacement device in
the event of a collision of the vehicle, said displacement device, in
turn, acting directly on the front gate and being detachably connected to
the same. The articulations of the four-bar mechanism on the side of the
front gate, are fixed to a pivoting lever in an articulated manner, the
pivoting lever being detachably fixed to the front gate with one end, in
the idle state, and being pivotable in relation to the front gate, with
the other end thereof, about a rotary articulation arranged on the front
gate in the region of the articulation of the displacement device. If the
vehicle crashes, the displacement device raises the front gate in
relation to the idle state in such a way that it is guided by the arms of
the four-bar mechanism and by the pivoting lever detaching itself on one
side from the front gate.
