2. The wiper blade device as claimed in claim 1 , characterized in that the at least two detent means ( 12 ; 12 a ; 12 b , 14 ; 14 a ; 14 b ) comprise in each case one deflection means ( 24 ; 24 a ; 24 b , 26 ; 26 a ; 26 b ), which deflection means are arranged offset with respect to one another in the wiper blade longitudinal direction ( 16 ; 16 a , 16 b ).

3. The wiper blade device as claimed in claim 1 , characterized in that the at least two detent means ( 12 ; 12 b , 14 ; 14 b ) comprise in each case one deflection means ( 24 ; 24 b , 26 ; 26 b ), which deflection means which are arranged on the opposite lateral sides of the wiper blade adapter, wherein the opposite lateral sides of the wiper blade adapter are receiving sides ( 28 ; 28 b , 30 ; 30 b ) which face toward one another, of the wiper blade adapter ( 10 ; 10 b ).

4. The wiper blade device as claimed in claim 1 , characterized in that the wiper blade adapter ( 10 ) comprises at least one first guide groove ( 32 ) which, viewed in the wiper blade longitudinal direction ( 16 ), extends as far as between the at least two detent means ( 12 , 14 ).

5. The wiper blade device as claimed in claim 4 , characterized in that the wiper blade adapter ( 10 ) comprises at least one second guide groove ( 34 ) which, viewed in the wiper blade longitudinal direction ( 16 ), extends as far as between the at least two detent means ( 12 , 14 ).

6. The wiper blade device as claimed in claim 1 , characterized in that the wiper blade adapter ( 10 ; 10 a ; 10 b ), between the at least two detent means ( 12 ; 12 a ; 12 b , 14 ; 14 a ; 14 b ) as viewed in the wiper blade longitudinal direction ( 16 ; 16 a , 16 b ), engages around the at least one spring rail ( 18 ; 18 a ; 18 b ) at both sides in at least one plane.

7. The wiper blade device as claimed in claim 1 , characterized in that the at least two detent means ( 12 ; 12 b , 14 ; 14 b ) are deflectable in different directions ( 42 ; 42 b , 44 ; 44 b ).

8. The wiper blade device as claimed in claim 1 , characterized in that the at least two detent recesses ( 20 ; 20 a ; 20 b , 22 ; 22 a ; 22 b ) of the at least one spring rail ( 18 ; 18 a ; 18 b ) are arranged on mutually averted sides of the at least one spring rail ( 18 ; 18 a ; 18 b ).

9. The wiper blade device as claimed in claim 1 , characterized in that the at least two detent recesses ( 20 ; 20 a ; 20 b , 22 ; 22 a ; 22 b ) are arranged axially symmetrically with respect to a central axis of rotation ( 46 ; 46 a ; 46 b ).

10. The wiper blade device as claimed in claim 1 , further comprising a wind deflector unit ( 48 ) which has a spring rail channel ( 50 ) accommodating the at least one spring rail ( 18 ).

11. The wiper blade device as claimed in claim 1 , wherein the at least two detent means are configured to initially deflect away from one another when the spring rail is inserted into the wiper blade adapter, and are configured to deflect toward one another prior to engaging in the at least two detent recesses.

12.

15. The wiper blade device as claimed in claim 14 , wherein the wiper blade adapter includes a body having an abutment web that defines a groove having a width that is smaller than a width of the spring rail, such that when the spring rail is inserted into the wiper blade adapter, the abutment web is configured to deform to provide room for insertion of the spring rail through the wiper blade adapter.

16. A wiper blade device having a wiper blade adapter ( 10 ; 10 a ; 10 b ) which comprises at least two detent means ( 12 ; 12 a ; 12 b , 14 ; 14 a ; 14 b ) which are spaced apart from one another along a wiper blade longitudinal direction ( 16 ; 16 a , 16
