The invention relates to a flow guiding apparatus of a motor vehicle, comprising a spoiler which is fastened to a tailgate of the motor vehicle, and to an adjustment kinematics device for adjusting the spoiler between a rest position, in which the spoiler is arranged in a flush-mounted manner in the tailgate, and at least one functional position, in which the spoiler is deployed beyond the vehicle contour or the surface of the tailgate with regard to the height and/or the angle. In order to achieve a downforce effect and/or braking effect and/or aerodynamic improvement during driving of the motor vehicle, the adjustment of the adjustment kinematics device takes place via actuable drive means. This flow guiding apparatus is intended to be developed in such a way that a multiplicity of operating positions of the spoiler can be set with a compact overall design and integration into the movable tailgate, with at least one operating position intended to fulfil the function of an air brake. For this purpose, the adjustment kinematics arrangement comprises at least one adjustment kinematics unit which is formed from a first adjustment kinematics system and a second adjustment kinematics system which is coupled to the former in an operatively connected manner, the first adjustment kinematics system being configured as a four-bar linkage and to set a deployment height, and the second adjustment kinematics system being configured as a four-bar linkage and to set a deployment angle, and an adjustment of the spoiler being a superimposed kinematic adjustment movement of the first and second adjustment kinematics system, and the first adjustment kinematics system comprising at least one pivoting axle which is mounted in a stationary manner and is pivotal via an electric motor as drive means, and the second adjustment kinematics system comprising a pivoting axle which is mounted in a stationary manner and is pivotable via a separately actuable electric motor as drive means.
