An apparatus for adjusting a screen arrangement for a vehicle roof may have a main slider and an adjusting slider which can each be coupled to the screen arrangement and are configured for pivoting the screen arrangement out and in and for adjusting a prescribed alignment angle (A) of the screen arrangement. The apparatus may also have a drive coupling element which couples a drive cable of the main slider and a drive cable of the adjusting slider to one another, such that the main slider and the adjusting slider can be displaced, with respect to a common reference point, at least in certain portions, at different movement speeds, and such that with respect to a longitudinal axis (L) of the apparatus a spacing between the main slider and the adjusting slider and therefore an alignment angle (A) of the screen arrangement can be adjusted in a prescribed manner.

A vibration and noise-reduced electric-motor device for an electrical household appliance or an electrical sliding roof. The invention includes a method for the vibration and noise-reduced operation of an electric-motor device. The electric-motor device has an electric-motor assembly, a main body, and a driven group of accessories. The electric motor assembly includes an electric motor, a control and evaluation unit, a data memory, a current regulator, a rotor angle sensor and a torque evaluator. The electric motor has a stator, a rotor and motor coils. In the method, a setpoint current stored in a value table in the data memory is applied to the motor coils in accordance with the rotor angle. The torque deviation resulting at the setpoint current, between the setpoint torque and the actual torque is determined, and an optimized new setpoint current value is calculated by interpolation and is written into the value table.

A bed cover for a vehicle that may be deployed electromechanically, either on demand or automatically, when a vehicle operator so desires, when predetermined weather conditions are detected, when the vehicle reaches a predetermined speed or experiences predetermined operating conditions, and/or when predetermined aerodynamic drag conditions are detected. The bed cover is deployable from a stowed configuration to one or more use configurations. These use configurations may include a traditional horizontal bed cover and/or an angled “cap-style” bed cover, with the angled bed cover providing enhanced aerodynamic drag reduction characteristics. A vehicle control module and camera, sensor, and/or stop trigger are used to ensure that is safe to deploy and use the bed cover, without negatively impacting an item, animal, or person present in the bed or rear cargo space of the vehicle.

A roof system comprises a panel movable between closed and open positions. An operating mechanism comprises front and rear devices. A slide moves the panel both in vertical and horizontal directions via the front and rear devices. At least one of the front and rear devices comprises a lever connected to the slide or the stationary rail through a second pivot pin. A first guide cam is at least partly in engagement with either a stationary guide and/or a curve in the slide. The slide includes a first and second slide part are pivotally connected to each other. One of the slide parts, that is pivotally and slidably connected to said lever, includes a cam engaging a guide curve in the stationary guide rail to force said one slide part to pivot with respect to the other slide part during at least a part of the sliding movement of the slide.

A vehicle roof opening having a cover and bearing device which displaceably supports the cover on a roof-side longitudinal guide rail a front and rear bearing unit, which moves the cover between a closed and at least one deployed ventilation positions. The front bearing unit may have a bearing arm, one end which pivotally mounts the cover and the other end which is slidingly and pivotally mounted on the longitudinal guide rail; carries out a positioning movement controlling the cover front region, when said cover is moved from its closed position into its ventilation position and/or into an open position. The bearing arm may be pivotally mounted by a rocker-type bearing having a pivot bearing and two sliding elements, on the longitudinal guide rail in a slidingly mounted bearing carriage, and a pivot-control unit guides the two sliding elements to achieve the rocker-type pivoting action of the bearing arm.

A retractable cover system includes laterally spaced apart guide rails that each provide a track on either side of an opening. The retractable cover system further includes a cover that has multiple slats that are configured to interlock with one another in a deployed configuration. The slats are slidable in the tracks between first and second positions within the opening. The slats are stacked onto one another in a stowed configuration. The slats include laterally extending profiles that are complementary to one another and are configured to interlock with one another in a deployed configuration. The complementary profiles are configured to decouple from one another in the stowed configuration.

The invention relates to an arrangement for operating an electric motor, for example an electric motor for actuating a roof component, in a vehicle. Therein, the electric motor is electrically connected via at least two control lines with a motor control unit. The motor control unit is configured to control the electric motor by means of pulse width modulation. The motor control unit is configured to operate a first one of the two drive lines as an inactive line, and to operate a second one of the two drive lines as an active line during control of the electric motor. A switching module associated with the electric motor is configured to connect a terminal of the pole housing of the electric motor with the drive line which is operated as the inactive line during operation of the electric motor. The invention further relates to an electric motor as well as to a method of operating an electric motor, for example an electric motor for actuating a roof component, in a vehicle.

A tandem drive device for at least one adjustable vehicle part, in particular for a sliding roof system, preferably comprising at least two sliding roof elements such as, for example, a glass roof and a roller shutter, wherein the tandem drive device includes at least a first drive system having a first gear mechanism and a first drive motor, and a second drive system having a second gear mechanism and a second drive motor, as well as a common control circuit for the first drive motor and the second drive motor, wherein the first gear mechanism and the second gear mechanism as well as the control circuit are accommodated in a common housing.

A movably arranged vehicle component is operatively coupled to and may be driven by an electric motor. The electric motor is supplied with a motor current to drive the movement of the vehicle component. A method for detecting a movement obstruction comprises the steps of supplying the electric motor with a supply voltage, thereby supplying the motor current; determining a frequency content of the motor current; and analysing the frequency content to determine whether the movement obstruction is present or not. A motor control system is configured to perform the above-mentioned method.

A roof module for a vehicle roof of a passenger vehicle includes a module frame which includes a front module frame transverse element, a rear module frame transverse element, a first lateral module frame longitudinal element, and a second lateral module frame longitudinal element, where the first and the second lateral module frame longitudinal elements connect the front and the rear module frame transverse elements to each other. A cover element is mounted on the module frame. The front module frame transverse element is a first shell element and the first shell element is connectable to a second shell element of a roof frame of the vehicle roof. When the first shell element is connected to the second shell element they together form a roof crossmember of the vehicle roof which encloses a cavity.
