Abstract:
A wireless passenger seat control device, particularly for an aircraft, has at least two ranges of functions. One of the ranges of functions includes seat adjustment. The operation of the device is simplified if the control units for the at least two ranges of function, particularly for the seat adjustment and the audio/video functions, are combined in one common housing and only mechanically attached to the seat.

Description:
BACKGROUND OF THE INVENTION  
   It is therefore an object of the present invention to unify the control of the infotainment functions and the seat functions. 
   In known seats for aircraft, trains and the like, control units are provided for so-called infotainment functions, which in the simplest case include volume and programs selection for audio transmissions. In more convenient units, particularly in aircraft, the control unit also includes control means for TV, video, e-mail, internet functions and, where appropriate, the telephone. Control units of this kind are physically and functionally separate from the control units for seat functions, which comprise seat adjustment and, where required, other seat functions. 
   When the controls for infotainment and for seat control are separately arranged in the way described, it is on the one hand necessary for this to be fitted and wired in the seat separately, which means that fitting is more expensive. On the other hand, the passengers are faced with two different control units, which may possibly be positioned in different places and may need to be operated in different ways. In practice, this is undesirable. 
   It is therefore an object of the present invention to unify the control of the infotainment functions and the seat functions. This is achieved by a control device having the features given in claim  1 . 
   SUMMARY OF THE INVENTION  
   This object is realized by a control device, for a passenger seat in a means of transport, having at least two ranges of functions, one of which includes seat adjustment. wherein control units for the at least two ranges of functions are combined in a common housing. 
   Because the control units are combined in one common housing they are at the same place, which means that they can fitted into a housing simultaneously in one assembly operation and can be found, all together, by the passenger. The way in which they operate can also be matched visually and electromechanically when this is the case. 
   The two control units are preferably situated in one housing of a hard-wired or wireless remote control for the seat. Where the remote control is wireless it may be connected to the seat, in such a way that it cannot be lost, via a fastening means which performs purely mechanical functions. 
   The control device may also be connected to an identifying unit which identifies the passenger and, if required, calls up and accepts stored values for the preferred seat setting or the preferred infotainment setting. In the simplest instance, the identifying unit is in this case a card reader, for chip or magnetic cards for example. The data for the preferred settings may be stored on the card and, on a different journey, may be called up again by a seat which operates in the same way on a different means of transport. 
   The identifying device may also be arranged to be a credit-card reader or a reader of cards held by members of frequent flyer programs. Chargeable services such as pay-TV, the internet or telephone may then be charged for at the same time via these cards. 

   
     BRIEF DESCRIPTION OF THE DRAWINGS  
     In what follows, an embodiment of the present invention is described by reference to the drawings. 
     In the drawings: 
       FIG. 1  is a plan view of a control device for an aircraft seat in the form of a hard-wired remote control; 
       FIG. 2  is a side view of the control device shown in  FIG. 1 ; and 
       FIG. 3  is a rear view of the control device shown in  FIG. 1 . 
   

   DESCRIPTION OF PREFERRED EMBODIMENTS  
     FIG. 1  is a plan view of a hard-wired remote control for an aircraft seat. A remote-control housing  1  comprises, in that part of a manipulable housing  2  which is at the top in  FIG. 1 , a switching member  3  for functions of the backrest of the seat, a switching member  4  for functions of the horizontal surface of the seat, and a switching member  5  for functions of the leg-rest or foot-rest. A further control  6  is provided for a lumbar support in the back-rest. 
   Also provided for the functions of the seat are a light-switch  7  and, at  8 , a total of four switches for pre-selected positions (eating, reading, resting, lying). 
   Below the controls for the seat functions is provided, at  10 , a section having controlling units for video functions (fast forward, rewind, start and stop). A display  11  shows the audio or video source selected or other functions. The screen situated in the passenger&#39;s field of vision can be switched on and off with an on-and-off switch at  12 . Service can be requested with a switch  13 . 
   Below the controls which have been described, there is in turn a switch  14  for channel selection, a volume control  15  and various changeover switches  16  for video, audio, screen brightness and a menu. All the functions which have been described up to this point are incorporated in the control unit  1 . When the passenger seat is being assembled, they can therefore be purchased as a single, fully prefabricated bought-in or manufactured part and can be connected to the seat by a connecting cable  20 . Consequently, this control unit is particular easy to fit and the fitting is particularly economical of time, and thus of cost as well. 
   For the user, this control device has the advantage that all the functions required for comfort and convenience during a journey can be found at the same point. There is no need for him to make a search for the different control units for the different comfort-enhancing functions and, particularly with the embodiment of a hard-wired remote control that is shown, he does not have to direct his attention to different control units. 
     FIG. 2  is a side-view, from the right, of the control device shown in  FIG. 1 . Built into the side of the housing of the control device  1  is a card reader  21  which has a slot  22 , open at the side, for the insertion of a magnetic card. 
   The personal details of the passenger can be queried with this magnetic card. On the card he can store seat settings that have been made personally, which may for example be assigned to the keys  8 . These preferred seat settings can then be called up again at a later date in a seat of similar or identical construction. Preferred settings for the audio and video functions may also be stored and called up and finally, charging data may be transmitted which enables the passenger to use chargeable infotainment services such as for example pay-TV, computer games or games of chance and internet functions and, where applicable, telephone, without these having to be charged for in a separate process which may possibly be seen as a nuisance. 
   It is also possible for functional devices for controlling internet, e-mail or other functions which require a user input to be provided on the back of the control device. Controls of this kind arranged on the back are identified in  FIG. 3  by reference numerals  23 ,  24  and  25 . 
   Although the present invention has been elucidated in the present case by reference to a control device which is constructed in the form of a hard-wired remote control, control devices of this kind may also be constructed in wireless form. In particular, it is also possible for a control device which transmits by wireless means to be connected to the given seat, in such a way that it cannot be lost, by a traction means such as a cable of rope-like form for example, thus doing away with the electrical cable connection, which may possibly be vulnerable mechanically.
