The invention relates to a blind arrangement for a vehicle, comprising a drive unit that is provided with a roller tube (10) for winding up a blind web, a roller shaft (14), and an electric motor (12) for driving the roller tube about the roller shaft, as well as a planetary gear (16), the roller tube being embodied as an internal gear of the planetary gear on the inner surface thereof. The invention further relates to a drive unit encompassing a roller tube (10) for winding up a blind web, a roller shaft (14), and an electric motor (12) for driving the roller tube about the roller shaft. The electric motor is provided with a stator and an armature (42). The stator is connected to the roller tube so as to rotate along with the roller tube when the roller tube rotates while the armature is mounted so as to rotate relative to the vehicle body when the roller tube rotates. The inventive electric motor is additionally equipped with sliding contacts (44) by means of which the electric motor is connected to a voltage source of the vehicle. Alternatively, the electric motor is connected to the voltage source of the vehicle, which is fixed to the vehicle body, by means of flexible wires (28) whose length and flexibility are selected such that the connection to the voltage source is maintained even when the electric motor travels a maximum rotational distance. Also disclosed is a blind arrangement for a vehicle, comprising a drive unit that is provided with a roller tube (10) for winding up a blind web and an electric motor (12) for driving the roller tube. Said blind arrangement further comprises a sliding clutch (22) in the drive train of the roller tube. |
