  • Patent number: 6213534
    Abstract: The present invention relates to a locking device for motor vehicle folding tops with a first connecting device (3) which, for the fixing of the folding top (9) to the motor vehicle, has a first closing mechanism with at least one second connecting device (5), which is positioned at an interval from the first connecting device (3) and a plug-like element (7), as well as a guiding element (85) suitable for the mounting of the plug-like element (7). The locking device is distinguished through the fact that the second connecting device (5) has a connecting device for the temporary locking of the plug-like element in the guiding element, and that the second locking device is connected with the closing mechanism in such a manner that, upon the fixing of the first closing mechanism into its closing position, the locking of the plug-like element (7) takes place at the same time.

  • Patent number: 6199936
    Abstract: The present invention relates to a motor vehicle folding top system with a foldable folding top (13) in which a rear window (43) is positioned, a rod which has articulated- or support rods (18, 19) supported in an articulated manner, several transverse support units (33) which extend in the transverse direction of the motor vehicle and serve for the tightening of the folding top (13), a folding top casing (5) in which the folded folding top (13) can be accommodated, and a folding top flap (7) which at least partially covers over the folding top casing (5). In accordance with the invention, the motor vehicle folding top system has a swivelling supporting device (23) for the rod in the area of the folding top casing (5), which can be swivelled from an upright locking position into a folded starting position of the folding top, in the direction of the rear of the motor vehicle.
