Abstract

A windscreen wiper device comprising at least one yoke which is attached to a carrier in such a manner as to be capable of pivotating movement about a first pivot axis, wherein both said carrier and said yoke have a substantially U-shaped cross-section at the location of their interconnection, said windscreen wiper device further comprising a oscillating arm pivotally connected to said carrier about a second pivot axis near one end, wherein said carrier is provided, at the location of said second pivot axis, with a transverse shaft, with the special feature that said oscillating arm and said carrier are interconnected with the interposition of a joint part, wherein said joint part comprises at least one resilient tongue engaging in a correspondingly shaped hole provided in said oscillating arm.

Claims

1. A windscreen wiper device comprising at least one yoke which is attached to a carrier in such a manner as to be capable of pivoting movement about a first pivot axis, wherein both said carrier and said yoke have a substantially U-shaped cross-section at the location of their interconnection, said windscreen wiper device further comprising an oscillating arm pivotally connected to said carrier about a second pivot axis near one end, wherein said carrier is provided, at the location of said second pivot axis, with a transverse shaft, wherein said oscillating arm and said carrier are interconnected with the interposition of a joint part, and wherein said transverse shaft is pivotally snapped in a correspondingly shaped recess in a downwardly extending portion of said joint part, said joint part including at least one resilient tongue engaging in a correspondingly shaped hole provided in said oscillating arm, wherein said oscillating arm has an at least substantially U-shaped cross-section at the location of its connection to said joint part, and wherein each leg of said U-shaped cross-section comprises inwardly bended edges which engage around longitudinal sides of said joint part that face away from each other, and said joint part including laterally outwardly projecting protrusions formed along said longitudinal sides of said joint part and extending beneath longitudinal lower edges of said legs of said oscillating arm adjacent said bent edges.

2. A windscreen wiper device according to claim 1, wherein said hole is provided in a base of said U-shaped cross-section of the arm.

3. A windscreen wiper device according to claim 1, wherein said hole has a closed circumference.

4. A windscreen wiper device according to claim 1, wherein said shaft is dimensioned such that it can be passed through an insertion opening of the recess from an at least substantially perpendicular position of said oscillating arm with respect to said carrier, and be locked in position in said recess from an at least substantially parallel position of said oscillating arm with respect to said carrier.

5. A windscreen wiper device according to claim 1, wherein said shaft is formed by a pin extending from one longitudinal side to another longitudinal side of said carrier.

6. A windscreen wiper device according to claim 1, wherein said joint part is made of plastic.
