According to an exemplary embodiment, there is provided a vision protection assembly for a passenger seat for on-demand use in an upright seating position, the privacy screen assembly comprising: a privacy screen; wherein the visual protection device is designed for attachment to a passenger seat or on a passenger seat.

Such a screen is extendable, for example, only during the cruise phase after takeoff. For safety-relevant flight phases, such as "take-off" or "landing", the privacy screen is always retracted so that inspection of the cabin by the cabin crew is possible at all times. During start-up or landing, the privacy screen can be retracted by an automatic or manually.

According to one exemplary embodiment of the invention, the retraction of the privacy screen is performed by a central control via a guidance system for a passenger compartment or a flight attendant control panel or an aircraft information system.

Such a privacy screen can be installed / integrated on or around a passenger seat as standard equipment or as a retrofit option.

According to an exemplary embodiment, the screening device has a plurality of elements which are designed for the fan-like telescoping or folding.

Such elements of the visual protection device can also be performed telescopically. The privacy screen can consist of several telescoping elements to ensure the smallest possible space when the screen is folded. The shape of the privacy screen fits in with the design of the interior of the interior used. The execution of the screen can be absolute opaque or be designed so that shadowing is possible. A "reading" of documents is excluded.

According to an exemplary embodiment, the screening arrangement can furthermore be designed to be infinitely variable in a fan-shaped manner, extendable or fold-out as required in a fixed grid. For example, an axis of rotation can be provided for this purpose.

Such a screening device can also be mounted on the axis of rotation in such a way that the screening device is telescopically extendable, extendable or fold-out as needed or in a fixed grid. The privacy screen can telescope or fan-like, for example, as a pleat, be executed. As a pleat, for example, a privacy of folded fabric can be understood.

Such an extension, extension or unfolding of the screening arrangement has the advantage that the smallest possible space can be guaranteed. In this case, an embodiment with a rotation axis or without a rotation axis is possible.

According to an exemplary embodiment, a mechanical adjusting device is further provided for the screening device, wherein the screen protection device is mechanically adjustable by means of the mechanical adjusting device of a passenger.

Such a mechanical adjustment of the screen can be done manually or by mechanical means. As mechanical aids electrical (motor), hydraulic / pneumatic (piston cylinder) or similar drives are provided. The mechanical adjusting device of the visual protection device can also be mechanically adjustable, for example via a control system of a stewardess, centrally. It is possible that several privacy devices for several passenger seats are simultaneously mechanically adjustable by the mechanical adjustment. This is particularly advantageous for the takeoff and landing phases in an aircraft, as this allows inspection by the cabin crew at any time in several cabins and thus, for example, to help needy passengers when putting on the belt.

According to an exemplary embodiment, the visual protection device of the privacy screen is designed for attachment to the backrest of the passenger seat.

This embodiment makes it possible that the privacy screen is partially integrated into the backrest, whereby a small space for the blind device is required.

According to an exemplary embodiment, the visual protection device of the privacy screen can be designed for attachment to a seat surface of the passenger seat.

This embodiment makes it possible to integrate the privacy screen device to save space partially in the seat.

According to a further embodiment, the visual protection device of the privacy screen is further designed for attachment to an armrest of the passenger seat.

Such attachment of the screening device to an armrest allows a space-saving mounting of the screening device with a partial integration in the armrest of the passenger seat.

According to an exemplary embodiment, the visual protection device of the privacy screen has at least one surface element.

This embodiment makes it possible that a plurality of surface elements can be used to form the screen, and are designed to be slidable with each other, that the surface elements of the screen can be moved into each other to save space or are collapsible.

According to the invention, the visual protection device of the privacy screen has a lighting device with which the passenger seat can be illuminated.

This makes it possible for the illumination device to be integrated into the privacy screen, for example, as a surface light, or the arealight can be completely designed as a privacy screen to additionally illuminate the passenger individually. Compared to existing spotlight illuminations (reading light), such a lighting device advantageously produces a uniform illumination of the passenger space. When using the illumination device as a surface light, the OLED technology (Organic Light Emitting Diode) can be used, which makes it possible to produce flat luminous bodies. These filaments are very thin and can also be made of a flexible material. When using the OLED technology, it is also possible to produce a more energy-efficient lighting device than previously used bulbs. The illumination device can be executed both as a monochrome unit and as a color unit.

The shape of a surface light can adapt to the environment of the interior used in design. The design can be completely opaque or designed so that shadowy view is possible.

According to a further embodiment, the illumination device of the privacy screen is implemented with OLED technology.

According to the invention, at least one of the elements of the screening device is designed as a surface-light segment.

This makes it possible for a plurality of surface light segments to be combined to form a collapsible, displaceable, foldable illumination device. As a result, the lighting device can be realized in the smallest possible space. All elements of the screening device can be designed as surface-luminous segments or a combination of privacy-protection elements and surface-area segments can be implemented.

This makes it possible that the lighting device can be mounted on the passenger seat or integrated into the passenger seat. The lighting device can also be designed for attachment to the seat surface of the passenger seat. An embodiment for fixing the lighting device to an armrest of the passenger seat is also possible. The above-mentioned different embodiments for mounting the lighting device allow an advantageous space-saving comfortable arrangement of the privacy screen on the passenger seat.

This also makes it possible that the lighting device can be pulled or -gefahren according to demand continuously or in a fixed grid accordingly. In this case, a mechanical adjustment of the surface light can be done manually or by mechanical aids, such as electric (motor), hydraulic / pneumatic (piston cylinder) or similar drives.

According to an exemplary embodiment, the sight protection arrangement further has a control unit, wherein light color, brightness and intensity of the illumination device can be set individually by the control unit.

This embodiment makes it possible for the illumination device to be set individually by a passenger or centrally by a control device. This has the advantage that a passenger can adjust light color, brightness and intensity of the illumination device, for example for reading or resting, for his individual comfort. At the same time, for example, by a stewardess, a special lighting in terms of light color, brightness and intensity, for example, when starting or landing the aircraft or in an emergency for one or more passengers can be set centrally.

According to an exemplary embodiment, the visual protection device of the privacy screen is foldable by the above-mentioned or an additional control unit.

This embodiment has the advantage that, for example, at take-off and landing several visual protection devices are retractable at any time, so that inspection of the passenger cabins from the cabin crew is possible. The inspection of one or more passenger cabins is a safety-related necessity in aviation.

According to an exemplary embodiment, an aircraft seat is provided with a blind arrangement according to the invention.

Thus, the mechanism for adjusting the privacy screen can be coupled to the control of the aircraft seat.

According to an exemplary embodiment, an aircraft is provided with a blind assembly according to the invention.

By this measure, an effective privacy screen for passenger seats is provided in an aircraft, which allows an improvement in privacy and the passenger and the lighting of the passenger seat to improve comfort for each passenger and at the same time by a central control of the mechanical adjustment of the screen a safety-relevant inspection of the Passenger cabins from the cabin crew allows.
