Windscreen wiper device

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.

What is claimed is: 
     
         1 . 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.   
     
     
         2 . The method as set forth in  claim 1  wherein the steps of plastically deforming the at least one carrier element is with a roller assembly. 
     
     
         3 . The method as set forth in  claim 1  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.
