  • Patent number: 7993070
    Abstract: A coupling member for pivotally coupling an end of a device to a mounting ball includes a body connectable to an end of the device and defines a socket for receiving a mounting ball. The body further includes slots communicating with the socket. A sliding element arranged in a longitudinal groove of the body is movable from a first position to a second position. A C-shaped spring has two ends and a center section, the ends being received through the slots and projecting into the socket for holding the mounting ball in the socket. The sliding element interacts with the center section of the spring when the sliding element is moved to the second position so that the ends of the spring are drawn out from the socket to release the mounting ball from the socket, whereby the mounting ball is releasable from the socket without external tools.

  • Patent number: 7900531
    Abstract: In a drive device for opening and or closing the hatch of a motor vehicle, the drive including a spindle drive with a threaded spindle and a nut, with a clutch arranged between the rotary drive and the spindle drive, the clutch includes a shifting element, a clutch element, and a clutch disk non-rotatably connected to the threaded spindle. The shifting element is rotatably drivably connected to the rotary drive. The shifting element has an axially oriented helical first ramp and the clutch element has an axially oriented helical second ramp in opposed contact with said first ramp. Relative rotation of the shifting element and the clutch element causes relative axial displacement of the shifting element and the clutch element against a spring force. The clutch element has a clutch area movable into non-rotatable engagement with the clutch disk in response to the relative axial displacement of the shifting element and the clutch element such that the rotary drive for the spindle drive also operates the clutch.
