Wischblatt für Scheiben insbesondere von Kraftfahrzeugen und Verfahren zum Herstellen des Wischblatts

摘要

The invention relates to a wiper blade (10) that is provided with an elongated, rubber-elastic wiper strip (16) that is placed against the glass surface (12). On both longitudinal faces the wiper blade is provided with respective longitudinal grooves (28 and 30) that are open towards the longitudinal faces (27). Respective elongated, spring-elastic bars (32 and 34) are accommodated by said groove. The two spring bars (32, 34) form a matching pair whose dimensional characteristics are adapted to a predetermined glass surface configuration and to other, vehicle-specific features. An improved wiping result and a smoother wiping operation can be achieved when the two spring bars (32, 34) of a pair of spring bars have different frequencies of resonance.
