Abstract: A method for actuating an electric motor with a motor control signal with an application-specific frequency, which signal is provided by an electronic motor control unit, wherein the electric motor is used in a vehicle roof for activating a component of this roof while being connected to a region of the roof. Embodiments provide that the electric motor can be actuated by the motor control unit with an additional signal whose frequency and amplitude are suitable for causing the region of the vehicle roof to which said electric motor is connected to oscillate in order to generate sound.

Abstract: A roller blind arrangement for a motor vehicle is disclosed which may have a roller blind web which has guiding tapes on its lateral edges on either side of a longitudinal center plane of the roller blind, a winding shaft onto which the roller blind web can be wound or from which the roller blind web can be unwound and which comprises a flexible hollow tube arrangement penetrated by a vehicle-attached mounting beam and comprising a flexible middle tube which is provided with bearing bushes in a co-rotating manner on both ends, each guiding tape of the roller blind web being attached to one bearing bush. At least one of the bearing bushes can shift relative to the middle tube in the longitudinal direction of the hollow tube.
