Abstract: The invention relates to a front hood arrangement on a vehicle, comprising a hinge mechanism that is located in the rear relative to the direction of travel and is embodied as a quadruple joint with a long and a short pull rod. The hinge mechanism allows the front hood to be swiveled during normal opening and closing while allowing the same to be raised in the rear zone during a collision of the vehicle. Such a hinge mechanism is provided with a spring element which actuates an adjusting lever during a collision while the adjusting lever acts directly upon the front hood and rests thereupon either directly or via intermediate elements. The joints of the quadruple joint located at the front hood end are hingedly fixed to a swiveling lever.

Abstract: 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 joints of the quadruple joint located at the front hood end are hingedly fixed to a swiveling lever. In the neutral position, one end of the swiveling lever is removably fastened to the front hood while the other end thereof can be swiveled relative to the front hood about a pivot joint that is disposed in the area where the adjusting lever is associated with the front hood.
