Benefits of technology

The invention aims to improve the performance of windscreen wiper devices by improving their wiping properties.

Problems solved by technology

One drawback of the prior art windscreen wiper device is the fact that, during oscillatory movements of the wiper blade, the connecting pieces may touch the respective A-pillars of the vehicle concerned, resulting in a rattling noise, air turbulence and sometimes in damages to the connecting pieces and / or longitudinal strips.
As a result, the wiping properties may deteriorate, whereas the wiper blade may come loose from the connecting pieces, particularly when the wiper blade and the connecting pieces are not connected in a durable, solid manner.
Hence, the life span of the prior art windscreen wiper device may be seriously shortened.

[0017]FIG. 1 shows a preferred variant of a windscreen wiper device 1 according to the invention. the windscreen wiper device is built up of an elastomeric wiper blade 2, wherein a central longitudinal groove 3 is formed, and of a central longitudinal strip 4 made of spring band steel, which is fitted in the longitudinal groove 3. the strip 4 forms a flexible carrier element for the rubber wiper blade 2, as it were, which is thus biased in a curved position (the curvature in operative position being that of a windscreen to be wiped). Free ends 5 of the strip 4 and / or wiper blade 2 remain free, that is there are no connecting pieces or end caps connected thereto on either side of the windscreen wiper device 1. The windscreen wiper device 1 is furthermore built up of a connecting device 6 of plastic material for connecting an oscillating wiper arm thereto, with the interposition of a joint part 8. Connecting device 6 comprises clamping members that are integral therewith, which engage...
