  • Publication number: 20080129088
    Abstract: A sliding roof system includes at least one guide rail, a cover that is displaceable relative to the guide rail, and a wind deflector that can be displaced between a lowered and a deployed position. At least two actuating elements act on the wind deflector in order to press the wind deflector out of the deployed position into the lowered position. An offset V is provided such that the sliding roof system is able to have one of the actuating elements act on the wind deflector while the other actuating element remains spaced apart from the wind deflector.

  • Patent number: 7234445
    Abstract: A device for actuating at least one throttle valve of an internal combustion engine is provided. When the throttle valve opening angles are small, the throttle valve and the actuating device are positively coupled, and when the throttle valve opening angles are large, the throttle valve and the actuating device are form lockingly coupled in the closing direction, but are only conditionally coupled in the opening direction, such that the throttle valve can be brought into operation for smaller throttle valve opening angles.
