  • Patent number: 9016757
    Abstract: A folding top frame has a corner bow with a lower end connected pivotably to a main bow. A load-bearing support is articulated pivotably on a folding top bearing, and has a guide slot, at an end opposite the folding top bearing. The corner bow is guided in the guide track by way of a journal. In the closed position of the folding top frame, the journal is at a lower end stop of the guide slot so that the corner bow is supported.
    Type: Grant

  • Patent number: 8899657
    Abstract: A simplified folding-top linkage is distinguished in that the two roof-frame links are articulated directly on the two roof-frame portions, in that one of the roof-frame links has an extension, which is angled in relation to said roof-frame link and extends beyond a point of articulation located on the second roof-frame portion, and in that the drive link is articulated on the extension and the coupling link.

  • Patent number: 7201413
    Abstract: A crash box for installation between a longitudinal member and a bumper cross member of a motor vehicle, includes a sheet metal body having a deformation member which extends anteriorly of an end surface of the longitudinal member and whose maximum crumpling capability defines the energy absorption of the crash box. In prolongation of the deformation member is an attachment member which is engaged in the longitudinal member and detachably secured by bolts therein. Formed in a transition zone between the deformation member and the attachment member, is a stop which is configured in the form of an outwardly directed material protuberance or outwardly directed thickened area of the sheet metal body and bearing against the end surface of the longitudinal member.
