Arrangement for increasing the buckling strength of windshield pillars of a vehicle

An arrangement for increasing the buckling strength of windshield pillars of a vehicle, particularly of the very inclined windshield pillars of a convertible, includes a supporting strut which interacts with an activating device. In its deposited position, the strut is aligned approximately horizontally and extends along an upper area of a side vehicle door having an inside door panel. In the event of danger, an end of the strut facing the windshield pillar is moved by an activating device into an operative position along a guide rail to an upper end area of the windshield pillar. The supporting strut, in its deposited position, is detachably fastened on an impression of the vehicle door facing the passenger compartment, whereas, in the swivelled-up position and in its operative position, the supporting strut is completely uncoupled from the vehicle door and, in the operative position, is on the one side connected in a force-transmitting manner with the upper end area of the windshield pillar and, on the other side with a receiving device which is arranged adjacent to the vehicle door and is fixed on the body side.
