  • Patent number: 5702150
    Abstract: A convertible has a stationary rollover bar on which a wind deflecting device can be fixed. In order to ensure, on the one hand, a good operation of the rollover bar and the wind deflecting device and, on the other hand, to not negatively influence the stylistic overall appearance of an open vehicle as a result of the rollover bar and the wind deflecting device, it is provided that the rollover bar comprises a tube section which extends approximately at the level of the belt line and in the transverse direction of the vehicle, bar sections which project upwards in laterally exterior areas leading away from the tube section. The wind deflecting device is composed of a center part and two lateral parts, the lateral part being inserted into the openings of the bar sections and the center part being inserted into the cutout of the rollover bar bounded by the bar sections and the transversely extending tube section.

  • Patent number: 5074612
    Abstract: A spoiler arrangement is arranged in the rear area of a fast back of a motor vehicle and, in the operative position, extends essentially above a rear window. So that the free design of the vehicle body is not impaired significantly and an effective protection of the spoiler arrangement is ensured when driving through an automatic car wash installation, the adjustably constructed spoiler arrangement is formed by a partial area of the rear window, the partial area in the retracted inoperative position, extending flush with the skin with respect to the adjacent rear window section.
