     TECHNICAL FIELD 
       [0002]    The present invention relates to a seat device with a universal device for receiving an electronic gadget for an aircraft or spacecraft. 
         [0003]    Although the present invention and the problem it addresses can be applied to any seat for an aircraft or spacecraft, they will be described with regard to an aircraft. 
       BACKGROUND 
       [0004]    To entertain passengers during the long travel time of long-haul flights, so-called in-flight-entertainment systems (IFE systems) have been used for many years which provide every passenger in his/her seat with a choice of multimedia products, such as a plurality of films in different languages or music channels. The passenger usually watches the films on a screen which is fixedly installed as part of the IFE system in the region of the backrest. 
         [0005]    However, IFE systems of this type require complex and cost-intensive certifications. For this reason, the IFE systems are not replaced during the entire period for which the seat is used, although systems of this type are under constant technical development. 
         [0006]    From the prior art, DE 10 2006 007 284 A1 discloses an entertainment system for an aircraft in which, as an alternative to the known IFE system in the seat, information for the passenger is provided on a window pane of the aircraft. A disadvantage of this arrangement is that the presentation of films on the window pane can be distracting and disturbing in the long run for adjacent passengers. 
       SUMMARY 
       [0007]    It is one idea of the present invention to provide a seat with an electronic gadget, for which a renewed complex certification during a subsequent replacement of the electronic gadget is unnecessary, and which is significantly more economical compared to known IFE systems. 
         [0008]    According thereto, a seat with a receiving device for an electronic gadget is provided inside the headrest of the seat, the screen of the electronic gadget being separated in terms of construction from the surface of the seat by a safety screen. 
         [0009]    The idea addressed by the present disclosure is to realise a structural uncoupling between the screen of the electronic gadget and the surface of the seat. 
         [0010]    An advantage of the present invention is that due to the above-mentioned separation between the screen of the electronic gadget and the seat, it is possible to dispense with the complex and cost-intensive certification of the seat when the electronic gadget is exchanged so that just a single certification of this type is required for the seat according to the invention. With this certification, the electronic gadget can then be replaced by another specimen of a similar mass. 
         [0011]    Thus, the present seat makes it possible for an airline to adapt an IFE system, obtained during the new acquisition of the aircraft, to the technical development of components of this type through exchange, the otherwise usual additional certification of the seat in respect of impact safety becoming unnecessary. At the same time, the safety screen ensures that the electronic gadget is inaccessible to passengers, thereby reliably preventing tampering with or theft of the electronic gadget. 
         [0012]    Furthermore, the cost of integrating an IFE system is considerably reduced for the seat manufacturer by the use of a standardised receiving device, as a result of which the costs of providing a seat of this type can be reduced. 
         [0013]    The exchangeability of the IFE system in the present seat means that the IFE system can be easily adapted to further developed subsequent models during the time the seat is used. This enhances the use and convenience for the passengers. Thus, the IFE system is formed in particular by the electronic gadget, and preferably by an electronic video device. 
         [0014]    In addition thereto, the standardised receiving device in the seat provides an open market for IFE systems, so that consequently, a relatively large choice of IFE systems is available to the airlines at the time when the seats are acquired. Furthermore, the standardised size of the receiving device advantageously ensures that in spite of different dimensions, a single receiving device can be used in each case for an electronic gadget produced by different manufacturers. 
         [0015]    Furthermore, the receiving device is configured to receive an electronic gadget in the form of a tablet PC or a PDA. The use of a tablet PC or of a PDA as the electronic gadget significantly reduces the acquisition costs thereof compared to a screen and to the components of a conventional IFE system, since tablet PCs and PDAs are products which are manufactured for the mass market and hence can be supplied cheaply. Furthermore, by now the screens of entertainment devices of this type are large enough to allow films to be presented thereon in an appropriately high resolution. Due to the continuous development and the fierce competition of electronic gadgets of this type, relatively short innovation cycles exist for these products, so that during the period of use of the aircraft seat, the passenger can benefit from the additional facilities of the relatively new electronic gadgets. 
         [0016]    Advantageous configurations and improvements of the invention are provided in the subclaims. 
         [0017]    According to a possible configuration, the seat has a headrest, the receiving device and the safety screen being arranged in the headrest. The arrangement of the receiving device and of the safety screen in the headrest of the seat advantageously makes it possible for the passenger to view the electronic gadget in the receiving device in a particularly convenient and ergonomically favourable manner, the passenger being able to view said gadget in a sitting position, substantially without any effort. Furthermore, the arrangement of the receiving device and thus of the electronic gadget inside the headrest ensures that said electronic gadget is inaccessible to the passenger. 
         [0018]    According to a further possible configuration, the size and/or shape of the safety screen substantially corresponds to the size and/or shape of the receiving device and of the electronic gadget. A configuration of this type of the safety screen ensures the complete covering of the screen of the electronic gadget in the receiving device and the provision of the safety screen also maximises the secure surface during the impact of the passenger&#39;s head in the event of an accident. 
         [0019]    According to a further possible configuration, the seat has an electric power supply or can be connected via a first interface to the electric power supply of the aircraft or spacecraft, and the receiving device has a second electrical interface for the electric energy supply of the electronic gadget. This means that the electronic gadget can be operated and/or charged continuously during the flight, even when the passenger is not using the gadget. 
         [0020]    According to a further possible configuration, the receiving device has on at least one side an opening which is configured such that the electronic gadget can be inserted sideways into the receiving device via this opening. If allowed by the installation space inside the headrest, the electronic gadget can be exchanged through the opening in the side, the receiving device remaining installed in the seat while this takes place. Alternatively, the receiving device can also be removed from the headrest by means of an easily detachable connection, the receiving device then being opened and the electronic gadget being exchanged outside the seat. 
         [0021]    According to a further possible configuration, the receiving device is configured such that the electronic gadget can be inserted from the front into the receiving device. The view from the front preferably emerges when the associated seat is viewed from the side on which the screen of the electronic gadget is arranged or, in an equivalent alternative thereto, this is the side which is opposite the side on which the screen of the electronic gadget is arranged. To exchange the electronic gadget, for example a cover is firstly removed which is arranged in the region of the headrest, and particularly in the contact region of the passenger with the headrest. The electronic gadget can then be removed from the front or frontally from the receiving device and the replacement gadget is then inserted into the receiving means in the same way. 
         [0022]    According to a further possible configuration, the receiving device is articulated with the safety screen. This makes it possible to use the receiving device with the safety screen as an adapter for the electronic gadget. If different electronic gadgets are to be used, different adapters merely have to be produced, while the seats themselves can remain unchanged. In this respect, in a device, the safety screen can be articulated by its upper edge to the receiving device and in a further embodiment, it can be articulated by its left, right or lower edge to the receiving device. The safety screen protects the gadget and the display of the gadget during critical flight phases. 
         [0023]    According to a further possible configuration, a retaining means is provided which is arranged in the seat and is configured to receive the receiving device and the safety screen, articulated thereto, particularly when the receiving device is closed. This makes it possible to easily install the adapter in the seat, said adapter being formed by the receiving device and the safety screen, and to exchange it, if necessary. 
         [0024]    According to a further possible configuration, the seat has an operating unit which is provided for operating the electronic gadget. This makes it possible for the passenger to operate the electronic gadget by a standardised operating unit, so that the relevant functions of the electronic gadget can be selected with the smallest possible number of operating buttons. 
         [0025]    According to a further possible configuration, the receiving device has a pivot device, the electronic gadget being accommodated in the pivot device such that the electronic gadget can be pivoted. This makes it possible for the passenger to adapt the viewing direction of the screen of the electronic gadget when the seat is inclined, so that the view of the screen can be optimally selected at all times. 
         [0026]    According to a further possible configuration, the safety screen is arranged on the back of the seat, in particular on the back of the headrest. This arrangement advantageously allows the construction of the seat to be adapted in respect of the safety screen, which is also required, and in respect of the receiving device with very little effort, since the known IFE systems with the fixedly installed screen are also arranged in this region. 
         [0027]    According to a further possible configuration, the safety screen consists of Plexiglas® or of a plastics material. 
         [0028]    According to a further possible configuration, the safety screen is configured such that it will not shatter when subjected to an external influence. A configuration of this type of the safety screen advantageously ensures that it satisfies all safety-relevant requirements imposed in a component of this type, so that when the safety screen is subjected to an external influence, no splinters are produced. Accordingly, the safety screen can consist of a plurality of superimposed sheets which each have an interposed protective film to collect splinters. 
         [0029]    According to a further possible configuration, the safety screen has a surface coating which makes the surface of the safety screen scratch-resistant. A surface coating of this type ensures that over the period of use of the seat, the passenger can always see a clear, unimpaired picture on the screen of the electronic gadget in spite of an external influence on the safety screen. 
         [0030]    Furthermore, an aircraft or spacecraft having at least one seat according to the invention is claimed.

       DETAILED DESCRIPTION 
       [0038]      FIG. 1  is a perspective view of a region of a headrest  20  for a seat  10  with a device  30  for receiving an electronic gadget (not shown) according to a first embodiment of the present invention. 
         [0039]    In its interior, the headrest  20  has the receiving device  30  which is coupled inside to a frame (not shown) of the seat  10 . The receiving device  30  is arranged substantially centrally with regard to the thickness of the headrest  20 . The receiving device  30  is arranged with regard to the height of the headrest  20  such that a screen for an electronic gadget (not shown) which is received by the receiving device  30  such that it can be exchanged, can be viewed comfortably by a passenger. The electronic gadget can be in particular an electronic video device. 
         [0040]    Arranged in the region of the surface of the headrest  20 , on the rearward side of the headrest  20  substantially congruently with the receiving device  30  is a safety screen (not shown), through which the screen of the electronic gadget can be viewed. The safety screen simultaneously ensures that the electronic gadget is inaccessible to the passenger, thereby reliably preventing tampering with, or theft of the electronic gadget. 
         [0041]    The receiving device  30  is substantially rectangular in shape. The receiving device  30  comprises an upper rail  31  and a lower rail  33  which are each arranged in parallel at a distance from one another and have a u-shaped profile. The upper rail  31  and the lower rail  33  are joined together on one side by a connecting element  32  which has a plug  35 , a socket  36  and an adapter  37 , each of which extends towards the inside of the receiving device  30 . 
         [0042]    The plug  35  is arranged in such a manner and is used to ensure that the electronic gadget is not accidentally installed upside-down in the receiving device  30 . Thus, the plug  35  can be arranged, for example, above the socket  36 . The socket  36  is provided as an interface for the electricity supply and for the provision of control commands for the inserted electronic gadget, so that a continuous operation of the electronic gadget is also ensured on long-haul flights. The socket  36  is connected by a first cable  39  to an electric power supply (not shown) of the seat  10 . The adapter  37  is preferably configured to form a stop for the electronic gadget in the installation position thereof. Thus, the adapter  37  can be cuboidal, for example. 
         [0043]    Arranged opposite the connecting element  32  is a pivotable closing element  34  which is coupled by a pivot shaft  38  to a longitudinal end preferably of the upper rail  31 . In the region of its free longitudinal end, the closing element  34  has a bent shape, the receiving device  30  being closed by this region and by the lower rail  33  via a closing mechanism (not shown). The electronic gadget is then exchanged by pivoting the closing element  34  to the side, thereby exposing an opening for removing the electronic gadget, so that the electronic gadget can be removed through this side opening and through which in turn the new electronic gadget can be inserted into the receiving device  30 . Thereafter, the closing element  34  is again pivoted towards the receiving device  30  and the receiving device is closed. 
         [0044]    Arranged under the receiving device  30  and in the region of the surface of the headrest  20  is an operating unit  70  which has a plurality of buttons  71 ,  72 ,  73 . The buttons  71 ,  72 ,  73  allow the selection of predetermined functions for operating the electronic gadget, the operating unit  70  evaluating the pressing of buttons  71 ,  72 ,  73  and converting them into corresponding electrical control commands. The operating unit  70  is connected to the socket  36  by a second cable  39  which transmits the control commands from the operating unit  70  to the electronic gadget. 
         [0045]    With reference to  FIGS. 2 and 3 , a further embodiment is illustrated for a seat  10  with a device  80  for receiving an electronic gadget  40 , where  FIG. 2  shows a side view of the region of the headrest  20  and  FIG. 3  shows a partial view from the front of the region of the headrest  20  for the seat  10  according to  FIG. 2 . 
         [0046]    On its inside, the headrest  20  has a receiving device  80  which is coupled by a pivot device  81  with the frame (not shown) of the seat  10  such that the receiving device  80  can be pivoted. The pivot device  81  is preferably configured in the manner of a peg. The pivot device  81  is arranged in the region of the outer surface of the receiving device  80 . The receiving device  80  has a mirror-symmetrical shape and consists of three u-shaped profiles which are arranged such that the inner faces thereof form a planar receiving surface for receiving an electronic gadget  40 , said electronic gadget  40  being in contact with at least two different surfaces of one profile. When viewed from the front, i.e. when the seat associated with the receiving device  80  is viewed from the side on which the screen of the electronic gadget  40  is arranged, the receiving device  80  is substantially u-shaped. The receiving device  80  and the pivot device  81  are arranged at a distance from the centre of the headrest  20  towards the rearward part of the headrest  20  with regard to the thickness of the headrest  20 . 
         [0047]    Arranged in the region of the outer surface of the headrest  20  is a safety screen  50  which substantially has the size and shape of the receiving device  80  and covers a screen of the electronic gadget  40  which is accommodated in the receiving device  80 . The safety screen  50  consists of Plexiglas® or of a transparent plastics material. The safety screen  50  has a thickness and construction such that when subjected to external influences, it satisfies all the safety requirements imposed on the safety screen  50 , such as the requirement that the safety screen  50  must be shatterproof. 
         [0048]    Arranged inside the headrest  20  is a plate-shaped head protector  90  which substantially extends over the entire width and the height of the headrest  20 . The head protector  90  can be pivoted via a pivot axle  91  which is arranged in the region below the centre of the head protector  90  and is received and mounted by the frame of the seat  10 . 
         [0049]    Arranged below the receiving device  80  in the region of the outer surface of the headrest  20  is an operating unit  70  which is substantially identical to the operating unit of  FIG. 1 . The operating unit  70  is connected by a cable  61  to an interface  60  which inputs the control commands from the operating unit  70  into the electronic gadget  40 . Furthermore, the interface  60  is connected to a further cable  61  which is connected to an electric power supply (not shown) of the seat  10 . 
         [0050]    In the region of its outer surface, the headrest  20  has a covering  100  which is arranged in the contact region between the passenger&#39;s head and the headrest  20 . The covering  100  is covered by an antimacassar  110  which extends over the length of the covering  100  on the surface thereof. To exchange the electronic gadget  40 , the antimacassar  110  and the covering  100  are removed from the headrest  20 , an opening in the frontal direction being exposed. The head protector  90  is then pivoted away from the inside of the headrest  20  until the opening is exposed. Finally, the receiving device  80  is pivoted by the pivot device  81  towards the outside of the headrest  20  until the electronic gadget  40  can be removed frontally through the opening. The new electronic gadget  40  is then installed in reverse sequence. 
         [0051]      FIG. 4  shows a view of an embodiment of the receiving device  30  according to the invention which is articulated to the safety screen  50 . The safety screen  50  is coupled to the receiving device  30 , for example by a hinge  130 . However, the safety screen  50  could also be coupled to the receiving device  30  by a coupler mechanism, for example a four-joint mechanism. In this manner, it is possible for the safety screen to perform a rotatory and translatory pivot movement relative to the receiving device  30  during opening and closing. 
         [0052]      FIG. 5  is a schematic view of a seat  10  with a retaining device  120  according to an embodiment of the invention. The retaining device  120  is arranged on the back of the seat  10 . In this embodiment, the retaining device  120  is in the form of a frame and is also configured to hold the receiving device  30  non-positively and/or positively. The retaining device  120  can also be provided with a catch device, for example a ball catch which catches into the receiving device  30 . The receiving device  30  could also be secured in the retaining device  120  by suckers and/or by a Velcro® fastening. 
         [0053]    Although the present invention has been described above on the basis of preferred embodiments, it is not restricted thereto, but can be modified in many different ways. 
         [0054]    For example, the receiving device can have adapters for adapting the vertical installation site for the screen of the electronic gadget in the case of different sized screens of different electronic gadgets.
