BACKGROUND OF THE INVENTION 
     The invention proceeds from a wiper device. 
     There is already known a wiper device for a motor vehicle window, with a wiper arm adapter unit and a wiper blade adapter unit which form a positive connection in a mounted state. 
     SUMMARY OF THE INVENTION 
     The invention proceeds from a wiper device for a motor vehicle window, with a wiper arm adapter unit and a wiper blade adapter unit which form a positive connection in a mounted state. 
     It is proposed that the wiper device has a housing means which is fixedly arranged on the wiper blade adapter unit and which is provided for receiving the wiper arm adapter unit in a linear push in movement, with the result that a particularly simple coupling of the wiper blade adapter unit with the wiper arm adapter unit can be achieved. A “wiper blade adapter unit” is intended to be understood as meaning in this connection in particular an adapter unit which has a region of contact in relation to a wiper blade component and is captively connected to the wiper blade component and provided for making available a coupling region of the wiper blade component for a coupling and/or contacting with the wiper arm adapter unit. The wiper blade adapter unit preferably has a basic body which makes available a coupling surface for the coupling and/or contacting of the wiper arm adapter unit. A “wiper arm adapter unit” is to be understood as meaning in this connection in particular an adapter unit which has a region of contact in relation to a wiper arm component and is captively connected to the wiper arm component and provided for making available a coupling region of the wiper arm component for a coupling and/or contacting with the wiper blade adapter unit. “Provided” is to be understood as meaning in this connection in particular especially equipped and/or designed. A “mounted state” is to be understood as meaning in this connection in particular a state in which the wiper blade adapter unit and the wiper arm adapter unit are coupled to one another. A “longitudinal direction” is to be understood as meaning in this connection in particular a direction which extends at least substantially parallel to a main extension direction of the wiper arm adapter unit. “Substantially” is to be understood as meaning in this connection in particular a deviation of less than 10°. Here, a “housing means” is to be understood as meaning in this connection in particular a means which forms a substantially visible outer surface in at least a mounted state and makes available a receiving region for the wiper arm adapter unit. “Substantially visible” is to be understood as meaning in this connection discernible in particular at a glance. 
     In a further refinement, it is proposed that the wiper blade adapter unit has a locking means which is provided for avoiding a push movement of the wiper arm adapter unit in the mounted state, with the result that a particularly secure coupling of the wiper blade adapter unit with the wiper arm adapter unit can be achieved. 
     A particularly simple mounting of the wiper arm adapter unit with the wiper blade adapter unit can be achieved if the locking means is designed as latching means. “A latching means” is to be understood as meaning in this connection in particular a means which experiences an elastic deformation during a mounting sequence. 
     If the latching means is formed in one piece with a basic body of the wiper blade adapter unit, the wiper device can be produced in a particularly simple manner. “In one piece” is to be understood in particular as meaning integrally bonded, such as, for example, by a welding process and/or adhesive bonding process, etc., and particularly advantageously as meaning integrally formed, such as through production by casting or production in a single or multi component injection molding process. 
     Furthermore, it is proposed that the locking means is pivotably mounted about a pivot axis. As a result, a mounting of the wiper arm adapter unit with the wiper blade adapter unit can take place in a particularly simple manner. 
     If the pivot axis is arranged at least substantially parallel to a longitudinal direction of the wiper arm adapter unit, a coupling of the wiper blade adapter unit with the wiper arm adapter unit can be achieved in a particularly reliable manner. “Substantially” is to be understood in this connection as meaning in particular a deviation of less than 10°. 
     In a further refinement, it is proposed that the pivot axis is arranged at least substantially parallel to a transverse direction of the wiper arm adapter unit, with the result that a particularly simple construction of the wiper arm adapter unit can be achieved. A “transverse direction” is to be understood in this connection as meaning in particular a direction which is perpendicular to the longitudinal direction and perpendicular to a vertical direction and runs parallel to a wiping plane. A “wiping plane” is to be understood as meaning in this connection in particular an idealized plane which, in an operating state, is wiped by a wiper blade fastened to the wiper blade adapter unit. Here, a “vertical direction” is to be understood as meaning in this connection in particular a direction which is perpendicular to the wiping plane. 
     If, in at least one operating state, the housing means forms at least a large part of a visible outer surface of the wiper blade adapter unit, the wiper device can be designed to be particularly robust. A “large part” is to be understood in this connection as meaning in particular more than 50%, preferably more than 70%. 
     If the housing means has at least one at least largely closed side wall, the wiper device can be advantageously protected from external influences, such as, for example, water. 
     In a further refinement, it is proposed that the wiper device has at least one securing means which is provided for avoiding a movement of the locking means in at least one operating state, with the result that an operational reliability of the wiper device can be advantageously increased.

     DETAILED DESCRIPTION 
       FIG. 1 a    shows a wiper device according to the invention with a wiper arm adapter unit  10   a  and a wiper blade adapter unit  12   a  in an opened state. 
     The wiper blade adapter unit  12   a  has a basic body  22   a  which is connected to a wiper blade  24   a . Fixedly arranged on the basic body  22   a  is a housing means  18   a  which partially rests on the wiper blade  24   a.    
     The housing means  18   a  has three side walls  20   a  which are each closed and form a large part of a visible outer surface of the wiper blade adapter unit  12   a . In a longitudinal direction  16   a , the housing means  18   a  is opened and thus allows the wiper arm adapter unit  10   a  to be received in a linear push in movement. 
     The wiper arm adapter unit  10   a  is formed in one piece with a wiper arm  26   a . However, it is also conceivable in this connection to form the wiper arm adapter unit  10   a  separately from the wiper arm  26   a  and to connect them to one another via a suitable connecting element. 
       FIG. 1 b    shows the wiper device in a mounted state. The wiper arm adapter unit  10   a  has been pushed into the housing means  18   a . Side walls  32   a  of the wiper arm adapter unit  10   a  terminate flush with an inner surface  40   a  of the three side walls  20   a  of the wiper blade adapter unit  12   a . A movement of the wiper arm adapter unit  10   a  in a transverse direction  54   a  and in a vertical direction  44   a  is thus avoided. 
     A locking means  14   a  arranged on the wiper blade adapter unit  12   a  and designed as latching means  56   a  formed in one piece with the basic body  22   a  terminates flush with rear stops  28   a  of the wiper arm adapter unit  10   a . The latching means  56   a  is arranged at an opening  30   a  of the housing means  18   a  and, during an insertion of the wiper arm adapter unit  12   a  into the housing means  18   a , is deflected in the transverse direction  54   a  from a starting position. In the mounted state, the latching means  56   a  moves back into its starting position. 
     A push out movement of the wiper arm adapter unit  10   a  parallel to the longitudinal direction  16   a  is thereby avoided. The wiper arm adapter unit  10   a  forms a positive connection with the wiper blade adapter unit  12   a.    
       FIGS. 2 to 6  show five further exemplary embodiments of the invention. The descriptions which follow are substantially restricted to the differences between the exemplary embodiments, it being possible to make reference to the description of the first exemplary embodiment with regards to components, features and functions which remain the same. To distinguish the exemplary embodiments, the letter a has been replaced in the reference signs of the exemplary embodiments in  FIG. 1  by the letters b to fin the reference signs of the exemplary embodiments of  FIGS. 2 to 6 . Regarding identically denoted components, in particular with regard to components having identical reference signs, reference can also be made in principle to the drawings and/or the description of the first exemplary embodiment. 
       FIG. 2 a    shows a further exemplary embodiment of a wiper device with a wiper arm adapter unit  10   b  and a wiper blade adapter unit  12   b  in an opened state. The wiper arm adapter unit  10   b  corresponds to the wiper arm adapter unit  10   a  from the first exemplary embodiment. 
     The wiper blade adapter unit  12   b  has a housing means  18   b  and also a locking means  14   b  which is pivotably mounted about a pivot axis  46   b  and which is formed as a cover flap  50   b . The pivot axis  46   b  is arranged substantially parallel to a longitudinal direction  16   b.    
     The wiper blade adapter unit  12   b  further has a basic body  22   b  which is formed in one piece with the housing means  18   b . The housing means  18   b  forms a large part of a visible outer surface  52   b  of the wiper blade adapter unit  12   b . Moreover, a counter stop  36   b  is arranged on the basic body  22   b.    
     The cover flap  50   b  is arranged laterally on the wiper blade adapter unit  12   b  and thus allows the wiper arm adapter unit  10   b  to be received in a linear movement which runs substantially parallel to a transverse direction  54   b.    
       FIG. 2 b    shows a second mounting step in which the wiper arm adapter unit  10   b  has been pushed into the basic body  22   b . The outer surface  52   b  limits a freedom of movement of the wiper arm adapter unit  10   b  in a vertical direction  44   b.    
     The counter stop  36   b  forms a positive connection with a rear stop  28   b  of the wiper arm adapter unit  10   b . A freedom of movement of the wiper arm adapter unit  10   b  is consequently limited in the longitudinal direction  16   b . A movement of the wiper arm adapter unit  10   b  is possible only parallel to the transverse direction  54   b.    
       FIG. 2 c    shows the wiper device in a mounted state. The cover flap  50   b  is closed and terminates flush with the outer surface  52   b  of the wiper blade adapter unit  12   b . As a result, the wiper arm adapter unit  10   b  is limited in its freedom of movement in the transverse direction  54   b.    
       FIG. 3 a    shows a further exemplary embodiment of a wiper device with a wiper arm adapter unit  10   c  and a wiper blade adapter unit  12   c  in an opened state. The wiper arm adapter unit  10   c  corresponds to the wiper arm adapter unit  10   a  from the first exemplary embodiment. 
     The wiper blade adapter unit  12   c  has a housing means  18   c  with a locking means  14   c  which is formed as a cover flap  50   c . The cover flap  50   c  is pivotably mounted about a pivot axis  46   c . The pivot axis  46   c  is arranged substantially parallel to a transverse direction  54   c  of the wiper arm adapter unit  10   c.    
     The housing means  18   c  has a visible outer surface  52   c  of the wiper blade adapter unit  12   c . Furthermore, a counter stop  36   c  is arranged on the housing means  18   c.    
     The cover flap  50   c  is arranged laterally on the wiper blade adapter unit  12   c  and thus allows the wiper arm adapter unit  10   c  to be received in a linear movement which runs substantially parallel to the transverse direction  54   c.    
       FIG. 3 b    shows the wiper device in a second mounting step in which the wiper arm adapter unit  10   c  has been pushed into the housing means  18   c . The outer surface  52   c  limits a freedom of movement of the wiper arm adapter unit  10   c  in a vertical direction  44   c.    
     The counter stop  36   c  forms a positive connection with a rear stop  28   c  of the wiper arm adapter unit  10   c . A freedom of movement of the wiper arm adapter unit  10   c  is thereby limited in a longitudinal direction  16   c . A movement of the wiper arm adapter unit  10   c  is possible only in the transverse direction  54   c.    
       FIG. 3 c    shows the wiper device in a mounted state. The cover flap  50   c  has been pivoted about the pivot axis  46   c  and terminates flush with the outer surface  52   c  of the wiper blade adapter unit  12   c . The wiper arm adapter unit  10   c  is limited by the cover flap  50   c  in its freedom of movement in the transverse direction  54   c.    
       FIG. 4 a    shows a further exemplary embodiment of a wiper device with a wiper arm adapter unit  10   d  and a wiper blade adapter unit  12   d  in an opened state. 
     The wiper blade adapter unit  12   d  has a housing means  18   d  with outer surfaces  52   d  and with a locking means  14   d  which is formed by a cover flap  50   d  which is pivotably mounted about a pivot axis  46   d . The pivot axis  46   d  extends parallel to a longitudinal direction  16   d.    
       FIG. 4 b    shows the wiper device in a second mounting step. The wiper arm adapter unit  10   d  has been pushed into the housing means  18   d  of the wiper blade adapter unit  12   d . The wiper arm adapter unit  10   d  is limited in a vertical direction  44   d  and also in the longitudinal direction  16   d  in its freedom of movement by the outer surfaces  52   d . A movement of the wiper arm adapter unit  10   d  is possible only in a transverse direction  54   d.    
       FIG. 4 c    shows the wiper device in a mounted state. The cover flap  50   d  has been pivoted onto the housing means  18   d  and terminates flush with the outer surfaces  52   d . Securing means  42   d  arranged on the cover flap  50   d  latch into place on the housing means  18   d  and prevent the cover flap  50   d  from pivoting back into the opened state. 
       FIG. 5 a    shows a further exemplary embodiment of a wiper device with a wiper arm adapter unit  10   e  and a wiper blade adapter unit  12   e  in an opened state. The wiper arm adapter unit  10   e  has a fastening cutout  34   e  and is formed in one piece with a wiper arm  26   e.    
     The wiper blade adapter unit  12   e  has a fixedly arranged housing means  18   e  which rests partially on a wiper blade  24   e  and is opened in a longitudinal direction  16   e . On the housing means  18   e , a locking means formed as a lever arm  38   e  is mounted pivotably about a pivot axis  46   e . The lever arm  38   e  has at one end a securing means  42   e  which is designed as a fastening pin. The pivot axis  46   e  is arranged substantially parallel to a transverse direction  54   e.    
       FIG. 5 b    shows the wiper device in a second mounting step. The wiper arm adapter unit  10   e  has been pushed into the housing means  18   e  of the wiper blade adapter unit  12   e  in the longitudinal direction  16   e . A movement of the wiper arm adapter unit  10   e  relative to the wiper blade adapter unit  12   e  in a vertical direction  44   e  or in the transverse direction  54   e  is thus avoided. 
       FIG. 5 c    shows the wiper device in a mounted state. The lever arm  38   e  has been pivoted about the pivot axis  46   e  and rests on the wiper arm adapter unit  10   e . The securing means  42   e  has been introduced into the fastening cutout  34   e  and forms a positive connection therewith. Consequently, a push out movement of the wiper arm adapter unit  10   e  in the longitudinal direction  16   e  is avoided. 
     In order to avoid the lever arm  38   e  being pivoted back into the opened state, the securing means  42   e  additionally forms a non-positive connection with the fastening cutout  34   e.    
       FIG. 6 a    shows a further exemplary embodiment of a wiper device with a wiper arm adapter unit  10   f  and a wiper blade adapter unit  12   f  in an opened state. The wiper arm adapter unit  10   f  corresponds to the wiper arm adapter unit  10   a  from the first exemplary embodiment. 
     The wiper blade adapter unit  12   f  has a housing means  18   f  which is connected to a wiper blade  24   f  via a swivel joint  48   f . A locking means  14   f  which is formed by a pivotably mounted lever arm  38   f  is arranged on a side wall  20   f  of the housing means  18   f  that is directed away from the wiper blade  24   f  The housing means  18   f  has an opening  30   f  in a longitudinal direction  16   f.    
       FIG. 6 b    shows the wiper device in a mounted state. The wiper arm adapter unit  10   f  has been pushed into the housing means  18   f . A freedom of movement in a vertical direction  44   f  and in a transverse direction  54   f  is thereby limited. By pivoting the lever arm  38   f , the latter terminates flush with the side wall  20   f  At the same time, the lever arm  38   f  engages in a fastening cutout  34   f  in the wiper arm adapter unit  10   f , and thus avoids a push out movement of the wiper arm adapter unit  10   f.
