Windscreen wiper device

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 the 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 a oscillating arm comprising two longitudinal arm sections connected to each other by a curved intermediate section, said oscillating arm being pivotally connected to said connecting device about a pivot axis, with the interposition of a joint part, wherein said joint part includes a resilient tongue engaging in a correspondingly shaped hole provided in said oscillating arm, and wherein said joint part and said connecting device are pivotally connected to each other by mutually cooperating protrusion and hole structure located below a longitudinal center plane between said two longitudinal arm sections, and wherein said joint part is detachably connected to said connecting device through a snapping or clipping operation wherein said resilient tongue includes at least one upwardly extending protrusion and at least one downwardly extending protrusion, said upwardly extending protrusion adapted to engage in a correspondingly shaped hole provided in an oscillating arm of a first type, and wherein said downwardly extending protrusion is adapted to engage in a correspondingly shaped hole provided in an oscillating arm of a second type, said oscillating arms of said first and said second types mutually differing in the distance between their respective longitudinal arm sections.

2. A windscreen wiper device according to claim 1 , wherein said resilient tongue is rotatable along a hinge axis between a first position,

wherein said upwardly extending protrusion is adapted to engage in said correspondingly shaped hole provided in said oscillating arm of said first type for retaining said wiper blade onto said oscillating arm of said first type, and wherein said downwardly extending protrusion is adapted to engage in said correspondingly shaped hole provided in said oscillating min of said second type for retaining said wiper blade onto said oscillating min of said second type, and a second position,

wherein said upwardly extending protrusion is adapted to disengage from said correspondingly shaped hole provided in said oscillating arm of said first type for releasing said wiper blade from said oscillating arm of said first type, and wherein said downwardly extending protrusion is adapted to disengage from said correspondingly shaped hole provided in said oscillating arm of said second type for releasing said wiper blade from said oscillating arm of said second type.

3. A windscreen wiper device according to claim 2 , wherein said hinge axis is located near an inner edge of said joint part.

4. A windscreen wiper device according to claim 2 , wherein said hinge axis is located near an outer edge of said joint part.

5. A windscreen wiper device according to claim 1 , wherein said upwardly extending protrusion and said downwardly extending protrusion are provided with an inclined surface.

6. A windscreen wiper device according to claim 1 , wherein said joint part has an at least substantially U-shaped cross-section at the location of its connection to said connecting device, and wherein said resilient tongue extends in longitudinal direction between legs of the U-shaped cross-section.

7. A windscreen wiper device according to claim 1 , wherein said correspondingly shaped hole is provided in a longitudinal arm section of said oscillating ann.

8. A windscreen wiper device according to claim 1 , wherein a cap is detachably connected to said joint part and/or said connecting device for retaining the said wiper blade onto said oscillating arm.

9. A windscreen wiper device according to claim 1 , wherein said joint part is connected to said connecting device by pivotally engaging protrusions of said connecting device, at the location of said pivot axis, in recesses provided in said joint part.

10. A windscreen wiper device according to claim 9 , wherein said joint part has an at least substantially U-shaped cross-section at the location of its connection to said connecting device, and wherein said joint part in each leg of said U-shaped cross-section is provided with a recess provided coaxially with said pivot axis.

11. A windscreen wiper device according to claim 9 , wherein the protrusions extend outwards on either side of said connecting device, and wherein the protrusions are at least substantially cylindrical.

12. A windscreen wiper device according to claim 1 , wherein said joint part is connected to said connecting device by pivotally engaging protrusions of said joint part, at the location of said pivot axis, in recesses provided in said connecting device.
