Embodiment Construction

[0018] refer to figure 1 and 8 , the windshield wiper device 1 includes an elastic wiper blade 2, opposite grooves 3 are formed on the sides of the wiper blade in the longitudinal direction, and also includes a longitudinal strip 4 made of elastic steel belt, which is installed in the longitudinal groove 3. The strip 4 forms a flexible carrier element for the wiper blade 2 , so that the wiper blade is in fact biased in a curved position (the curvature in the working position is equal to the curvature of the windshield to be wiped) . Adjacent ends 5 of the strips 4 on each end of the wiper blade 2 are connected to each other by clamping connectors 6 or "end caps". In this embodiment, the connector 6 is a separate structural element, which can be locked by form-locked ("positive locking" or "with positive fit") or by force (force-locked) connected to the end 5 of the strip 4. In another preferred embodiment, the connecting piece 6 and the strip 4 made of spring steel strip...
