Claim:
Arrangement of a front gate ( 27 ) on a vehicle, having at least one hinge device ( 1 ) that lies in the rear, viewed in the direction of travel, in the form of a four-bar mechanism ( 3 , 4 ) having a long and a short arm, whereby the front gate ( 27 ) can be pivoted during normal opening and closing, by means of the hinge device ( 1 ), and can be raised in the rear region in the case of a collision of the vehicle, wherein the hinge device ( 1 ) has an energy accumulator ( 2 ) that activates a displacement device ( 17 , 28 ) in the case of a collision of the vehicle, which device in turn acts directly on the front gate ( 27 ) and stands in a releasable connection with it, whereby the front-gate-side articulations ( 19 ) of the four-bar mechanism ( 3 , 4 ) are fixed in place on a pivoting lever ( 15 ), in articulated manner, which lever is releasably fixed in place on the front gate ( 27 ) in the state of rest, with one end, and can be pivoted relative to the front gate ( 27 ) with its other end, about a rotary articulation ( 6 ) disposed on the front gate ( 27 ) in the region ( 18 ) of the articulation of the displacement device ( 17 , 28 ), and the displacement device ( 17 , 28 ) raises the front gate ( 27 ), guided by the arms ( 3 , 4 ) of the four-bar mechanism, and the pivoting lever ( 15 ) that is released from the front gate ( 27 ) on one side, as compared with the state of rest, in the case of a collision of the vehicle.
