Windscreen wiper device
First Claim
1. A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips of said carrier element are disposed, wherein neighbouring ends of said longitudinal strips are interconnected by a respective connecting piece, which windscreen wiper device comprises a connecting device for an oscillating wiper arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis near one end, characterized in that said connecting device comprises engaging members being welded to longitudinal sides of said longitudinal strips that face away from each other in such a manner as to withstand shearing forces in a direction along said longitudinal strips, said connecting device and said engaging members being constructed as one piece of thermoplastic material and said longitudinal strips having an outer thermoplastic skin welded to said connecting device.
