## Abstract

A windscreen wiper device is provided. The windscreen wiper device includes an elongated wiper strip of a flexible material for sealing against the windshield and at least one elongated groove. At least one flexible and elongated carrier element is disposed in the at least one groove of the wiper strip for biasing the wiper strip into a predetermined configuration when in a relaxed state. The at least one carrier element presents at least one upwardly facing curve and at least one downwardly facing curve when in a relaxed state.

## Claims

### Claim 1

A windscreen wiper device for cleaning a windshield of a vehicle, comprising:
an elongated wiper strip of a flexible material for sealing against the windshield and having at least one elongated groove;
at least one flexible and elongated carrier element disposed in said at least one groove of said elongated wiper strip for biasing said elongated wiper strip into a predetermined configuration when in a relaxed state; and
wherein said at least one carrier element presents at least one upwardly facing curve and at least one downwardly facing curve when in a relaxed state.

### Claim 2 (depends on 1)

The windscreen wiper device as set forth in claim 1 wherein said at least one carrier element presents a pair of said downwardly facing curves separated from one another by a single upwardly facing curve such that it is generally M-shaped in said relaxed state.

### Claim 3 (depends on 2)

The windscreen wiper device as set forth in claim 2 wherein said at least one elongated groove on said elongated wiper strip is further defined as a pair of elongated grooves and wherein said at least one carrier element is further defined as a pair of carrier elements.

### Claim 4 (depends on 3)

The windscreen wiper device as set forth in claim 3 further including a frame structure having at least two sets of claws in engagement with said carrier elements.

### Claim 5 (depends on 4)

The windscreen wiper device as set forth in claim 4 wherein at least two of said sets of claws are in engagement with said carrier elements at locations approximately between said upwardly facing curves and said downwardly facing curve.

### Claim 6 (depends on 4)

The windscreen wiper device as set forth in claim 4 wherein said at least two sets of claws is further defined as at least four pairs of claws.

### Claim 7 (depends on 6)

The windscreen wiper device as set forth in claim 6 wherein said sets of claws are slidable relative to said carrier elements to support said carrier elements while also allowing for sliding movement of said carrier element relative to said frame structure.

### Claim 8 (depends on 7)

The windscreen wiper device as set forth in claim 7 wherein said carrier elements extend between opposite ends and wherein said frame structure extends outwardly past said opposite ends of said carrier elements and includes a pair of flanged portions configured to present stopping points for said sliding movement of said carrier element relative to said frame structure.

### Claim 9 (depends on 4)

The windscreen wiper device as set forth in claim 4 wherein said frame structure has an outer surface with a spoiler shape.

### Claim 10

A method of making a windscreen wiper device comprising the steps of:
preparing at least one flexible and elongated carrier element; plastically deforming the at least one carrier element to give it at least one upwardly facing curve when in a relaxed state; and
plastically deforming the at least one carrier element to give it at least one downwardly facing curve when in a relaxed state.

### Claim 11 (depends on 10)

The method as set forth in claim 10 wherein the steps of plastically deforming the at least one carrier element is with a roller assembly.

### Claim 12 (depends on 10)

The method as set forth in claim 10 further including the step of engaging the at least one carrier element with a wiper strip to bias the wiper strip into a configuration having at least one upwardly facing curve and at least one downwardly facing curve.
