Patent ID: 8549696

Claim:
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 arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis near one end, with the interposition of a joint part, said windscreen wiper device is provided with first and second retaining means for retaining said connecting device onto said oscillating arm, said first retaining means comprising at least one resilient tongue provided on said joint part engaging in at least one correspondingly shaped hole provided in said oscillating arm, said second retaining means comprising at least one first stop surface provided on said oscillating arm and at least one second stop surface provided on at least one of said joint part and said connecting device, both first and second stop surfaces being spaced apart during normal operation of said windscreen wiper device, wherein in case of disfunctioning of said first retaining means said connecting device is allowed to move with respect to said oscillating arm causing said second stop surface to correspondingly move towards said first stop surface until said first and second stop surfaces are adjacent one another, wherein said second stop surface is operative to move towards said first stop surface in a longitudinal direction of said wiper blade towards the free end of said oscillation arm, wherein said oscillating arm has an at least substantially U-shaped cross-section at the location of its connection to said joint part, wherein said first stop surface is provided on a leg of said U-shaped cross-section, wherein said first stop surface is formed by a transverse pin extending inwardly, and wherein each leg comprises clamping members formed as inwardly bended edges integral with said legs of said U-shaped cross-section and engaging round longitudinal sides of said joint part that face away from each other and serving to further enhance the retention of said oscillating arm onto said connecting device and joint part in a vertical direction.
