## Abstract

The invention relates to a wiper blade device comprising a wiper blade adapter (10) and a wiper strip unit (12). According to the invention, said wiper strip unit (12) has at least one securing recess (14) which, in at least one operating state, forms an interlocking connection with the wiper blade adapter (10).

## Claims

### Claim 1

A wiper blade device having a wiper blade adapter (10) and having a wiper strip unit (12), characterized in that the wiper strip unit (12) has at least one fastening recess (14) which, in at least one operating state, forms a positive fit with the wiper blade adapter (10).

### Claim 2 (depends on 1)

The wiper blade device as claimed in claim 1, characterized in that the wiper blade adapter (10) has at least one fastening means (16) which, in at least one operating state, forms a positive fit with a wind deflector element (20) of the wiper strip unit (12) and prevents a movement of the wiper strip unit (12) relative to the wiper blade adapter (10) in a longitudinal direction (18).

### Claim 3 (depends on 1)

The wiper blade device as claimed in claim 1, characterized in that the wiper strip unit (12) has at least one resiliently elastic carrier element (46) which, in at least one operating state, forms a positive fit with the wiper blade adapter (10).

### Claim 4 (depends on 3)

The wiper blade device as claimed in claim 3, characterized in that the positive fit between the carrier element (46) and the wiper blade adapter (10) prevents a movement of the carrier element (46) relative to the wiper blade adapter (10) in the longitudinal direction (18).

### Claim 5 (depends on 4)

The wiper blade device as claimed in claim 4, characterized in that the carrier element (46) has at least one detent means (48) which, in at least one operating state, forms a detent connection with the wiper blade adapter (10).

### Claim 6 (depends on 1)

The wiper blade device as claimed in claim 1, characterized in that the wiper strip unit (12) has a wind deflector element (20) and a wiper lip (22) which are formed in one piece.

### Claim 7 (depends on 1)

The wiper blade device as claimed in claim 1, characterized in that the wiper blade adapter (10) has a longitudinal guide unit (24) which receives a carrier element (46) with a positive fit.

### Claim 8 (depends on 1)

The wiper blade device as claimed in claim 1, characterized in that the wiper strip unit (12) has a longitudinal guide channel (26) which receives a carrier element (46) with a positive fit.

### Claim 9 (depends on 1)

A wiper strip unit (12) of a wiper blade device as claimed in claim 1.

### Claim 10 (depends on 1)

A wiper blade adapter (10) of a wiper blade device as claimed in claim 1.

### Claim 11 (depends on 1)

A method for assembling a wiper blade device as claimed in claim 1, characterized in that the wiper blade adapter (10) is mounted onto the wiper strip unit (12), wherein at least one fastening means (16) of the wiper blade adapter (10) engages into the fastening recess (14) with a positive fit.

### Claim 12 (depends on 11)

The method as claimed in claim 11, characterized in that, after the wiper blade adapter (10) is mounted onto the wiper strip unit (12), a carrier element (46) of the wiper strip unit (12) is inserted into a further component of the wiper strip unit (12) and into a longitudinal guide unit (24) of the wiper blade adapter (10).
