    • In a wind deflector for installation in a vehicle roof in a front area, comprising a wind deflector body which extends in a direction of extension transversely to a direction of travel, a lifting device, with which the wind deflector body can be moved between a position retracted into the vehicle roof and a position extended out of the vehicle roof and projecting beyond a contour of the upper side of the vehicle roof and thus deflecting wind, wherein the lifting device has at least one lifting unit with a mounting base and a lifting arm which is mounted with a lifting arm bearing for pivoting about a first pivot axis relative to the mounting base and engages on the wind deflector body at an end located opposite the lifting arm bearing, in order to achieve a reliable movability of the wind deflector body with devices which are as mechanically simple as possible it is suggested that an actuating unit which is supported on the mounting base and engages on the lifting arm be provided for moving the lifting arm and that the actuating unit and the lifting arm bearing be displaceable relative to one another in a direction of displacement extending transversely to the first pivot axis of the lifting arm bearing for the purpose of pivoting the lifting arm.
    • 在用于安装在前部区域的车顶中的挡风板中,包括一个横向于行进方向的延伸方向延伸的导风板本体,一个提升装置,导风板主体可以通过该提升装置在一个位置 缩回到车顶和从车顶延伸出的位置并且突出超过车顶的上侧的轮廓并因此偏转风,其中提升装置具有至少一个具有安装基座和提升臂的提升单元 其安装有用于围绕相对于安装基座的第一枢转轴线枢转的提升臂轴承,并且在与提升臂轴承相对的端部处接合在导风板主体上,以便实现导风板主体与可靠运动 设备尽可能机械地简单,建议将支撑在安装基座上并与升降臂接合的致动单元设置为m 驱动提升臂,并且致动单元和提升臂轴承可以在横向于提升臂轴承的第一枢转轴线延伸的位移方向上相对于彼此移位,以便枢转提升臂。
