Description:
BACKGROUND 
       [0001]    The invention is based on a seat operation unit. 
         [0002]    Seat operation units with light-emitting units are already known. 
       SUMMARY 
       [0003]    The invention is based on a seat operation unit, particularly an aircraft seat operation unit, having at least one light-emitting unit. 
         [0004]    It is proposed that the seat operation unit comprise an adjusting unit which is intended to electronically adjust the light intensity and/or light color of the light-emitting unit. In this context, a “seat operation unit” is intended to be understood to mean particularly a unit which a person in a seat can use to make inputs, such as particularly adjustments. In this case, the seat operation unit may have just one input unit associated with a seat apparatus or else a plurality of input units associated with one and/or else more seat apparatuses. 
         [0005]    An “adjusting unit which can be used to electronically adjust a light intensity and/or a light color” is intended to be understood to mean particularly a unit which comprises an electronics unit and/or preferably a processor unit and which can be used to produce various, in particular constant, light intensities, particularly not equal to zero and/or light colors particularly without interchanging light-emitting means. In addition, “intended” is intended to be understood to mean particularly specially equipped, designed and/or programmed. 
         [0006]    An appropriate embodiment allows a high level of flexibility to be achieved, specifically both for a passenger and/or also particularly for an interior designer, such as particularly an aircraft cabin designer. In this case, the adjusting unit is preferably intended to allow at least individual adjustments to be made only by a member of specialist personnel, so that individual, undesirable alterations by a passenger can be prevented. In particular, the seat operation unit can be matched, with little complexity, to different constraints and particularly to different customer requirements, such as particularly airlines. When used over a large area, it is advantageously possible to take account of design aspects, specifically particularly when the adjusting unit can be used to adjust a plurality of light-emitting units, associated with a plurality of seat apparatuses, centrally. In addition, it is a simple matter to compensate for instances of dimming caused by aging. 
         [0007]    Preferably, the adjusting unit is intended to be at least partially integrated into a seat apparatus, which allows advantageous simple actuation to be achieved. In this case, “integrated” is intended to be understood particularly to mean that at least a portion of the adjusting unit forms a mounting unit together with a seat apparatus, such as particularly with a single seat apparatus in an aircraft. Advantageously, at least a portion of the adjusting unit is also arranged centrally, so that a plurality of seat operation units, particularly also as plurality of seat rows, can advantageously be actuated together. 
         [0008]    In a further embodiment of the invention, it is proposed that the processor unit be at least partially in integral form with a seat control unit, which allows components, weight, mounting complexity and/or costs to be saved. In this case, a “processor unit” is intended to be understood particularly to mean a unit which comprises a processor or a computation unit and a memory unit with an operating program stored therein. 
         [0009]    In addition, it is proposed that the seat operation unit have a processor unit which is intended to adjust at least one adjusting operation at least semi-automatically on the basis of at least one parameter, which allows particularly convenience to be increased. By way of example, present room illumination can be taken as a basis for automatically adjusting the color and/or the light intensity of the seat operation unit. 
         [0010]    The light-emitting unit may have various light-emitting means which appear appropriate to a person skilled in the art. Particularly advantageously, however, the light-emitting unit has at least one light-emitting diode and/or a light-emitting foil which can be integrated in a particularly space-saving manner and also can be advantageously actuated in order to obtain different light intensities and/or light colors. In this connection, a light-emitting foil is intended to be understood particularly to mean a foil of multilayer design, specifically particularly with a layer which is formed by a rear electrode, a layer which is formed by an insulator, a layer which is formed by a light-emitting material and a layer which is formed by a front electrode. In this case, the light-emitting unit may have light-emitting diodes in one color, in different colors and/or also light-emitting diodes which emit different light colors depending on an applied voltage and/or frequency. 
         [0011]    If the light-emitting unit has light-emitting means which are intended to emit light in different colors, adjustment can be achieved by means of a simple design, specifically particularly if the adjusting unit is intended to produce different light colors by mixing, particularly differentiated mixing, of light colors, wherein at least one output color is produced by mixing light from at least two light sources in different colors and/or preferably at least emitted light in a particular color from at least one light source is used for at least two output colors. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS  
         [0012]    Further advantages can be found in the description of the drawing which follows. The drawing shows an exemplary embodiment of the invention. The drawing, the description and the claims contain numerous features in combination. A person skilled in the art will expediently also consider the features individually and combine them to form appropriate further combinations. 
           [0013]      FIG. 1  is a side view of a seat apparatus, and 
           [0014]      FIG. 2  is a schematic illustration of a seat operation unit and a seat control unit in the seat apparatus of  FIG. 1 . 
       
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0015]      FIG. 1  shows a seat apparatus  14  in an aircraft or an aircraft seat apparatus in a side view with a seat housing  24 , within which a backrest  26  and a seat base—not shown in more detail—are arranged. The seat apparatus comprises a console  28  and a seat operation unit, integrated therein, with a light-emitting unit  10 . The seat operation unit can be used by a passenger to adjust the seat base and the backrest  26  via a seat control unit  18  in the seat apparatus. 
         [0016]    The seat operation unit has an adjusting unit  12  which is intended to adjust the light intensity and light color of the light-emitting unit  10  electronically, i.e. particularly without interchanging light-emitting means ( FIG. 2 ). In this case, the adjusting unit  12  is intended to be operated exclusively by a member of specialist personnel, i.e. not by a passenger. 
         [0017]    The adjusting unit  12  comprises a processor unit  16  which is in partially integrated form with the seat control unit  18 , specifically the processor unit  16  and the seat control unit  18  have a common computation unit  30  or a common processor. In addition, the seat control unit  18  and the adjusting unit  12  are supplied with direct current by means of a common power supply unit  40 . 
         [0018]    In addition, the adjusting unit  12  comprises a memory unit  32  which stores an operating program. The memory unit  32  has an interface  34  which can be used to interchange an operating program locally on the seat apparatus  14 , specifically by installing a new operating program and/or by deactivating a selected operating program and activating an operating program which is already stored in the memory unit  32 . As an alternative and/or in addition, an operating program could also be arranged for a plurality of seat apparatuses centrally in a memory unit and/or an interface  48  could be provided which can be used to access a plurality of memory units, so that the operating program can be changed centrally for a plurality of seat apparatuses  14 , particularly also for a plurality of seat rows, as indicated in  FIG. 2 . The seat control unit  18  comprise a memory unit  36  with an operating program stored therein which can be interchanged centrally via an interface  38 , i.e. the operating program can be interchanged centrally simultaneously particularly for a plurality of seat apparatuses  14 . 
         [0019]    In addition, the processor unit  16  is intended to perform an adjusting operation on the basis of present room illumination. For this purpose, the processor unit  16  is supplied with data about the present room illumination via a data bus  42  and via an interface  44 . 
         [0020]    The light-emitting unit  10  has a light-emitting foil  22  and a plurality of light-emitting diodes  20  which are intended to emit light in different colors. The processor unit  16  is used to actuate the light-emitting foil  22  and the light-emitting diodes  20  via an electronics control converter  46 . 
         [0021]    The light-emitting foil  22  is intended to emit light of different intensity and in different colors, whereas the processor unit  16  is intended to use the light-emitting diodes  20  to produce different light colors by mixing light colors.
