Abstract

A windscreen wiper device comprising an elongated wiper blade of a flexible material, a connecting device, a mounting head, and a longitudinal strip-shaped arm. The wiper blade is adapted to be placed in abutment with a windscreen to be wiped. The wiper blade includes at least one groove in which an elastic, elongated carrier element is disposed. The connecting device is connected to the wiper blade. The mounting head transfers a reciprocal movement to the wiper blade. The longitudinal strip-shaped arm has a first end detachably connected to the mounting head through a snapping operation and a second end detachably connected to the connecting device through a snapping operation. The arm is made of a resilient material and is biased to exert a pressure onto the wiper blade towards the windscreen to be wiped.

First claim

The invention claimed is:

1. A windscreen wiper device comprising:
an elongated wiper blade of a flexible material, adapted to be placed in abutment with a windscreen to be wiped, wherein said wiper blade includes at least one groove in which an elastic, elongated carrier element is disposed, a connecting device connected to said wiper blade;
a mounting head for transferring a reciprocal movement to said wiper blade; and
a longitudinal strip-shaped arm having a first end detachably connected to said mounting head through a snapping operation and a second end detachably connected to said connecting device through a snapping operation, wherein said arm is made of a resilient material and is biased to exert a pressure onto said wiper blade towards the windscreen to be wiped, wherein said mounting head comprises at least one resilient tongue engaging in a correspondingly shaped hole provided in said arm near said first end thereof, and wherein said resilient tongue is hingeable between a wiping position retaining said arm onto said mounting head and a lift position releasing said arm from said mounting head.

2. The windscreen wiper device according to claim 1 , wherein said connecting device comprises at least one resilient tongue engaging in a correspondingly shaped hole provided in said arm near said second end thereof, wherein said resilient tongue is hingeable between a wiping position retaining said wiper blade onto said arm and a lift position releasing said wiper blade from said arm.

3. The windscreen wiper device according to claim 2 , wherein said hole has a closed circumference.

4. The windscreen wiper device according to claim 2 , wherein said resilient tongue extends in a longitudinal direction away from said mounting head.

5. The windscreen wiper device according to claim 2 , wherein said connecting device, comprises a first part and a second part, wherein said arm, can be pivotally connected to said first part about a pivot axis, with the interposition of said second part, wherein said second part comprises said resilient tongue, wherein said first part is connected to said wiper blade and said second part is detachably connected to said first part.

6. The windscreen wiper device according to claim 5 , wherein said second part is detachably connected to said first part by pivotally engaging protuberances of said first part, at the location of said pivot axis, in recesses provided in said second part.

7. The windscreen wiper device according to claim 6 , wherein said second part has a substantially U-shaped cross-section, wherein a base of said U-shaped cross-section comprises said resilient tongue, and wherein legs of said U-shaped cross-section comprise said recesses.

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

9. The windscreen wiper device according to claim 1 , wherein said resilient tongue extends in a longitudinal direction towards said mounting head.

10. The windscreen wiper device according to claim 1 , wherein said mounting head is fixed for rotation to a shaft, and wherein said shaft is rotatable alternately in a clockwise and in a counter-clockwise sense carrying said mounting head into rotation.

11. The windscreen wiper device according to claim 1 , wherein said mounting head is fixed for translation to a carriage, and wherein said carriage can be translated alternately in a linear direction and a counter linear direction carrying said mounting head into translation.

12. The windscreen wiper device according to claim 1 , wherein an elongated cap is connected to at least one of said mounting head, said arm and said connecting device.

13. The windscreen wiper device according to claim 12 , wherein said mounting head has two opposite side walls at the location of its attachment to said cap, wherein each side wall comprises a guiding groove cooperating with an inwardly extending protrusion on a wall of said cap.

14. The windscreen wiper device according to claim 13 , wherein said protrusion comprises a lateral rib to limit movement of said arm in a direction away from the windscreen to be wiped from a wiping position into a lifting position.

15. The windscreen wiper device according to claim 1 , wherein said windscreen wiper device further comprises two connecting pieces each positioned near an end of said wiper blade and connected to an end of said carrier element.

16. A strip-shaped arm arranged to be directly and detachably connected near a first end thereof to a mounting head of a windscreen wiper device through a snapping operation and arranged to be directly and detachably connected near a second end thereof to a connecting device of a wiper blade of a windscreen wiper device through a snapping operation, said arm being made of a resilient material and biased in order to exert a pressure onto the wiper blade towards a windscreen to be wiped, wherein:
said arm comprises a first hole and a second hole,
said first hole is adapted to cooperate with a resilient tongue of the connecting device that is movable between a wiping position retaining the wiper blade onto said arm and a lift position releasing the wiper blade from said arm, and
said second hole is adapted to cooperate with a resilient tongue of the mounting head that is movable between a wiping position retaining said arm onto the mounting head and a lift position releasing said arm from the mounting head.
