Windscreen wiper device
A windscreen wiper device, particularly for automobiles, comprises an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade is of the flat blade type and includes at least one groove, in which groove an elastic, elongated carrier element is disposed, wherein the windscreen wiper device further comprises a mounting head for transferring a reciprocal movement to the wiper blade, with the special feature that the windscreen wiper device further comprises a longitudinal strip-shaped arm, wherein the arm near a first end thereof is directly connected to the mounting head and near a second end thereof is directly connected to a connecting device of the wiper blade, and wherein the arm made of a resilient material is biased in order to exert a pressure onto the wiper blade towards the windscreen to be wiped.
1. A windscreen wiper device, comprising an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one groove, in which groove an elastic, elongated carrier element is disposed,
wherein said windscreen wiper device further comprises a mounting head for transferring a reciprocal movement to said wiper blade,
wherein said windscreen wiper device further comprises a longitudinal strip-shaped arm having opposing longitudinal exterior sides,
wherein said arm near a first end thereof is directly connected to said mounting head and near an opposite second end thereof is directly connected to a connecting device of said wiper blade,
wherein said arm is made of a resilient material and is biased in order to exert a pressure onto said wiper blade towards the windscreen to be wiped,
and wherein said windscreen wiper device further comprises an elongated cap connected directly to said arm adjacent said first end thereof and connected directly to said connecting device adjacent said second end of said arm, wherein said cap comprises a stop service to limit a movement of said arm in a direction away from the windscreen to be wiped from a working position into a lifting position.
2. A 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.
3. A windscreen wiper device according to claim 1 , wherein said arm is detachably connected to said connecting device through a snapping operation.
4. A windscreen wiper device according to claim 1 , wherein said arm and said mounting head are interconnected through a crimping operation.
5. A 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.
6. A windscreen wiper device according to claim 1 , wherein said cap further includes a pair of opposing side walls each having a plurality of longitudinally spaced apart ribs extending therefrom for engaging said longitudinal exterior sides of said arm to releasably secure said cap to said arm between said mounting head and said connecting device.
7. A windscreen wiper device according to claim 6 wherein said connecting device has a pair of opposing sides, and wherein said connecting device includes a protrusion projecting outwardly from each opposing side thereof and said cap includes a recess formed in each opposing side wall thereof for receiving said protrusions and attaching said cap to said connecting device.
8. A windscreen wiper device according to claim 7 , wherein said arm near said first end thereof includes two opposing recesses formed in said longitudinal exterior sides.
9. A windscreen wiper device according to claim 8 , wherein said mounting head has a substantially U-shaped cross-section at its attachment to said arm, said U-shaped cross-section having legs with clamping members formed as inwardly bent edges at an end portion of said legs for engaging said longitudinal exterior sides of said arm, and wherein said mounting head includes opposing, inwardly extending protrusions on said legs for engaging into said recesses of said arm.
10. A windscreen wiper device according to claim 9 , wherein said connecting device includes at least one resilient tongue engaging a correspondingly shaped hole provided in said arm near said second end, and wherein said resilient tongue is movable between a second working position retaining said wiper blade onto said arm and a rest position releasing said wiper blade from said arm.
11. A windscreen wiper device according to claim 7 , wherein said cap is connected directly to said arm via engagement of said ribs of said cap with said longitudinal exterior sides of said arm, and said cap is connected directly to said connecting device via engagement of said protrusions of said connecting device with said recesses of said cap.
