Abstract

A wiper blade (10) is proposed that serves to clean windows of motor vehicles. The wiper blade has an elongated, rubber-elastic wiper strip (14) which is provided on its two long sides with respective facing longitudinal grooves (38, 40), in each of which one spring rail (30, 32), protruding intermittently from the grooves by one longitudinal edge (42, 44), is disposed; the spring rails belong to an elongated, spring-elastic support element (12) for the wiper strip (14), on whose middle portion a connection device (16) for a wiper arm (18) guided on the vehicle body is disposed. An especially simple disposition of a wind deflector strip and a connection device for a wiper arm are obtained if at least one longitudinal portion of the part of the wiper strip located on the side of the spring rails (30, 32) remote from the window is embodied as a wind deflector strip (54), and if furthermore the connection device (16) is retained on the longitudinal edges (42, 44) of the spring rails (30, 32) that protrude from the longitudinal grooves (38, 40).

Dependent claims

A wiper blade for cleaning windows of motor vehicles, said wiper blade comprising

an elongated, rubber-elastic wiper strip (14) provided with respective longitudinal grooves (38,40) on corresponding opposite long sides thereof and with a wiper lip (28) for contact with a window (26);
an elongated spring-elastic support element (12) for the wiper strip (14), said support element (12) having corresponding spring rails (30,32) engaged in and protruding from the longitudinal grooves (38,40) provided in the wiper strip (14);
a connection device (16) for a wiper arm (18) connected to a middle portion of the support element (12), wherein said spring rails (30,32) have longitudinal edges (42,44) arranged outside of the longitudinal grooves (38,40) and said connection device (16) is held on the longitudinal edges (42,44) of the spring rails (30,32);
and
a wind deflector strip (54) comprising at least one longitudinal portion of the wiper strip, said at least one longitudinal portion being located on a side of the spring rails (30,32) remote from the wiper lip (28);
and
retaining means (34,36) for said spring rails (30,32), wherein said wind deflector strip (54) is provided with at least one recess (62) for receiving said retaining means, said at least one recess (62) extending longitudinally along said wind deflector strip (54) nearly to the longitudinal grooves (38,40), and said retaining means (34,36) extend across said wind deflector strip (54).
