  • Patent number: 11168770
    Abstract: A drive mechanism for adjusting a position of a vehicle closure, with respect to a vehicle body, is provided. The drive mechanism may include a linear drive and a telescoping arrangement. The linear drive may include a spindle and a spindle nut and the telescoping arrangement may be coupled to the spindle nut and include a pair of gears coupled to one another.

  • Patent number: 9260899
    Abstract: The invention relates to a drive device for a hatch of a motor vehicle, wherein the drive device comprises two drive sections that are linearly moveable relative to each other between a retracted position and an extended position, wherein the drive sections are spring biased against each other into the extended position by a spring arrangement, wherein an end stop is provided to limit the drive motion between the drive sections to the extended position. It is proposed that the end stop comprises a damping arrangement with a deformation zone, wherein during a drive motion into the end stop, depending on the speed of the drive motion, the damping arrangement damps the drive motion mainly based on plastic deformation of the deformation zone.

  • Patent number: 7798572
    Abstract: A manual adjustment of a back support on a vehicle seat includes a cable pulley which is selectively rotatable in a drive direction or in a driven direction oriented counter to the drive direction, and a tensile device associated with the cable pulley, which may be rolled up onto the cable pulley by rotating the cable pulley in the drive direction. The tensile device is able to be coupled to a back support of a vehicle seat such that the rotation of the cable pulley in the drive direction and/or driven direction affects an adjustment of the back support. A pretensioning acts on the cable pulley -which produces a torque of the cable pulley in the driven direction.
