Patent number: 6322131Abstract: The invention relates to a convertible vehicle with a roof, which can be folded up and is provided with a rear window, it being possible, in the closed position of the roof, to lower the rear window at least regionally from a normal position into a lowered position below a window parapet line forming the upper boundary of the car body. In order to simplify the installation of a movable rear window for such an embodiment, provisions are made so that the rear window, in the lowered position as well as in the normal position, is held in a frame, which is firmly connected with the roof, as a result of which special adjustment of the rear window or of a different component with respect to the roof is superfluous.Type: GrantFiled: March 20, 2000Date of Patent: November 27, 2001Assignee: Wilhelm Karmann GmbHInventors: Joachim Maass, Frank Lehnig

Patent number: 6302470Abstract: A convertible vehicle with a roof, which can be folded up, is provided with a rear window, can be stowed in a rear region of the vehicle and is braced over at least one tension bracket in the closed state with respect to the car body, the tension bracket being pivotable in the forwards direction for opening the roof and hereby bringing about a forward displacement of the rear window. In the case of such a construction, in order to be able to carry out the forward shifting of the rear region of the folding top, comprising the rear window, without being obstructed by upright parts, such as the rear head supports or roll bars, provisions are made so that the rear window is held in a frame which, on the folding top side, is opened downward and, during the opening and closing of the roof, can be swiveled up with respect to this frame.Type: GrantFiled: March 20, 2000Date of Patent: October 16, 2001Assignee: Wilhelm Karmann GmbHInventors: Joachim Maass, Frank Lehnig

Patent number: 6270143Abstract: A folding top for a convertible has a lateral folding linkage with linkage legs lying opposite to one another in pairs, symmetrically to the longitudinal center plane of the vehicle. The parallelogram links of the linkage legs form a front and a rear four-bar chain, which is supported in the region of a common connecting leg with at least three hinge points. In the case of the inventive folding top, the connector between the two four-bar chains is constructed as a cantilever girder supporting a rear guiding leg of the front four-bar chain as well as a front main guide bar of the rear four-bar chain with a height distance in in each case one of its hinge points and the front four-bar chain with the front link forming the third hinge point is assigned to this cantilever girder.Type: GrantFiled: October 26, 2000Date of Patent: August 7, 2001Assignee: Wilhelm Karmann GmbHInventors: Udo Heselhaus, Wolfgang Richter

Patent number: 6193301Abstract: For a convertible vehicle with a top, which can be locked to the windshield frame, for which at least one movable handle is provided for carrying out the locking and unlocking, the handle can be transferred from its operating position, in which it is accessible to a movement, which brings about the locking or unlocking of the top, into an inoperative position, which is located essentially vertically upwards from the operating position, in which it is in an area, which does not limit the head freedom. When the handle in the inoperative position is lowered into a recess formed between lining parts, a flush closure of the handle with the lining parts can be attained.Type: GrantFiled: September 28, 1998Date of Patent: February 27, 2001Assignee: Wilhelm Karmann GmbHInventors: Andreas Baumeier, Melanie Eitermann

Patent number: 6094798Abstract: A component, particularly for land vehicles, preferably a car body component for motor vehicles, consists of a metallic foam material with a foamed porous layer comprising a metal powder and a blowing agent and possibly at least one solid metal sheet, there being metallic bonds between the solid metal sheet and the foamed porous layer. The component has at least one stamped contour which is raised from its surface, the angles, occurring in the region of the transitions between the three-dimensionally molded contour and the surface region being of the order of 100.degree. to 180.degree.. To produce the component, an essentially flat, metallic foam material, which is provided with solid metal sheets as covering layers, is initially shaped into a semi-finished molded product, which is end-contoured on one side, and the semi-finished molded product, so formed, is placed into a foaming mold, one wall of which is adapted to the end-contoured side of the semi-finished molded product, and foamed therein.Type: GrantFiled: August 16, 1999Date of Patent: August 1, 2000Assignee: Wilhelm Karmann GmbHInventors: Hans-Wolfgang Seeliger, Winfried Bunsmann

Patent number: 5558390Abstract: A rear-window pane of solid glass is insertable in the folding top cover of a convertible. The solid glass pane is provided with a plastic connecting element which is applied on the edge region of the solid glass pane and can be connected with the cover of the folding top by means of high frequency welding. With this arrangement, an additional reinforcing is no longer required and, accordingly, the advantages of a plastic window pane are combined with the longevity and stability of the glass material.Type: GrantFiled: June 14, 1995Date of Patent: September 24, 1996Assignee: Wilhelm Karmann GmbHInventors: Ludger Hemmis, Matthias Overberg, Burkhard Schroder
