A vehicle window shade assembly includes a plurality of roller units each positioned within a cab of a vehicle. Each of the roller units is aligned with an upper threshold of a respective one of a plurality of windows in the vehicle. A plurality of screens is each attached to a respective one of the roller units. Each of the screens is rolled onto the respective roller unit when the respective roller unit is turned on to expose the window corresponding to the respective roller unit. In this way the plurality of screens facilitates sunlight to pass through the respective window. Each of the screens is unrolled from the respective roller unit when the respective roller unit is turned off to cover the window corresponding to the respective roller unit. In this way the plurality of screens can shade an interior of the vehicle from sunlight.

A shading device for a vehicle roof includes at least one shading length that can be rolled up for shading a light-permeable and/or open area of the vehicle roof, a tension bow that is movably mounted in a direction of travel (V), to which the shading length-is fastened, a drive mechanism that can be operated by a drive motor to move the tension and a control unit for activating the drive motor. The shading device includes at least one opposing force element for restricting a traveling movement of the tension bow, and the control unit is designed to activate the drive motor based on an opposing force when the tension bow reaches an end position (P1, P2) defined by the stop element.

A pneumatic shade includes a plurality of slats, a plurality of first fold members, and a plurality of second fold members. Each slat is elongated and includes and spans laterally between opposite longitudinal edges. Each of the first- and second-fold members are elongated and co-extend longitudinally with the slats. Each first fold member is attached to longitudinal edges of the respective adjacent slats. Each second fold member is attached to longitudinal edges of respective adjacent slats and are alternatingly orientated with respect to the first fold members such that each slat spans laterally between a respective first fold member and second fold member. Each of the first fold members and the second fold members are adapted to move between a folded state and an unfolded state upon application of pressurized air.

The present invention refers to a window sun blind arrangement having a control circuit, which comprises at least one braking unit having a braking MOSFET-switch M2. The braking unit is configured to introduce an electrical power within the control circuit after decoupling the control circuit from an electric power supply into the motor unit in a reverse direction, as compared to its original operating direction, for braking its current movement. Moreover, the present invention refers to an appropriate control circuit, to a vehicle with such a window sun blind arrangement or control circuit and to various methods for operating such window sun blind arrangements.

The present invention refers to a window sun blind arrangement having a control circuit, which comprises a second switching unit having a MOSFET-switch M1. The second switching unit comprises a control unit CU configured to operate the MOSFET-switch M1. The MOSFET-switch M1 has an activated operation state, in which electrical power can be supplied from an electric power supply to a second power port of a motor unit via a second power supply path II, and a non-activated operation state, in which electrical power cannot be supplied from the electric power supply to the motor unit via the second power supply path II. The control unit is configured to operate the MOSFET-switch M1 in the activated operation state, when a current flowing through the MOSFET-switch M1 and the motor unit does not exceed a predetermined threshold value, and to operate the MOSFET-switch M1 in the non-activated operation state, when the current flowing through the MOSFET-switch M1 and the motor unit exceeds the predetermined threshold value. Moreover, the present invention refers to an appropriate control circuit, to a vehicle with such a window sun blind arrangement or control circuit and to various methods for operating such window sun blind arrangements.

A window sun blind arrangement having a control circuit. The control circuit comprises a first switching unit having a micro-switch MS. The first switching unit has a non-activated operation mode, in which electrical power can be supplied from an electric power supply to a first power port of a motor unit via a first power supply path I in a first direction, and an activated operation mode, in which electrical power cannot be supplied from the electric power supply to the motor unit via the first power port of the motor unit and in which the electrical power within the control circuit is introduced into a second power port of the motor unit in a second, reverse direction. The first switching unit is configured to be switched from the non-activated operation mode to the activated operation mode when a drop bar of the window sun blind arrangement reaches its upper end position or its lower end position.

A device (1) for covering a surface is provided. The device includes: (a) a cover (10) of which each longitudinal edge is provided with a bead (12); (b) a rotatably mounted drum (2) capable of winding or unwinding the cover, movable on rails placed on either side of said surface; and (c) a system for continuously locking/unlocking the bead in the rails during the translation of the drum.

A system for vehicular power shade control is provided. The system includes a power shade operable to selectively deploy and retract in relation to a corresponding window of a vehicle, a sensor providing data related to the vehicle, and a computerized power shade controller. The computerized power shade controller operates programming to monitor the data from the sensor, compare the data to a threshold value, and generate a command to the power shade based upon the comparing.

An automated retractable sun shield system for a vehicle, comprising a sun shield, a deployment mechanism, a roller, a tension bar, and a controller. The sun shield includes a flexible material which blocks sunlight. The deployment mechanism operates to deploy and retract the sun shield. The sun shield wraps around the roller so that the sun shield is in a rolled configuration when the sun shield is retracted and stored. The tension bar guides the sun shield to match a shape of the tension bar when the sun shield is deployed. At least one element comprising the sun shield system is installed and concealed behind a dashboard valence panel of the vehicle. At least one element comprising the sun shield system is installed and concealed behind an interior trim covering a vertical support of the vehicle.

A wireless power transfer system for a vehicle door glass includes: a door glass having an electric load, and a pair of electrodes connected to the electric load; a power transmitter mounted in a vehicle door, and wirelessly transmitting power of a battery; and a power receiver embedded in the door glass, and wirelessly receiving the power from the power transmitter, wherein the power receiver applies the power received from the power transmitter to the pair of electrodes of the door glass.
