ABSTRACT:
A latching mechanism for a foldable top at a windshield frame of a motor vehicle includes a pivot lever arranged on the side of the top and a mounting device provided at the windshield frame, whereby the pivot lever rotatably supported about an approximately horizontally aligned longitudinal axis cooperates with an actuating mechanism. In order to provide a latching mechanism for a top which has a good functioning combined with simple construction and in which the closing force acting in the vertical direction reaches its maximum value in the latching position of the top, the mounting device is formed by a rotatable roller which cooperates with a guide track provided at the pivot lever in such a manner that during the closing operation the guide track is displaced from an unlatched position extending laterally adjacent the roller about the lower area of the roller by way of intermediate positions into a latching position lying underneath the roller. The points of rotation of the pivot lever and of the roller are located on a common vertically extending auxiliary plane. During the closing operation, the upper point of rotation of the pivot lever travels downwardly along the auxiliary plane. In the latching position, the area of the guide track tangential to the roller is aligned at right angle to the vertical auxiliary plane.
