A wiper blade (10) for windows, in particular of motor vehicles, is proposed that is equipped with a long, rubber-elastic wiper strip (14) that can be placed against the window (22), that is situated parallel to the longitudinal axis on a long, spring-elastic carrier element (12) to which a component (16) belonging to a device for attaching the wiper blade (10) to a driven wiper arm (18) is directly connected, whereby the carrier element (12) has springs (28, 30) designed in the shape of a strap lying in front of the window (22) in a plane that is basically parallel to the window, the bottom surfaces of the strap (13) of which face the window, the inner, adjacent longitudinal edges (32) of which have a distance between them and plunge individually into longitudinal grooves (54, 56) assigned to each longitudinal edge and open toward the longitudinal side of the wiper strip, and that are connected to each other by way of at least two transverse ribs (36) situated in the longitudinal direction with distance between them. A reliable and stressfree attachment of the wiper strip to the carrier element is insured when each transverse rib (36) has a center section (42) that extends at a distance from the top strap surfaces (11) of the springs (28, 30) so that bridge-like transverse ribs result, whereby the distance (34) between the two springs is less than the bridge width (46), and means of attachment (74, 76, 78) are situated on the carrier element (12) to secure the wiper strip (14) to the carrier element (12) in its longitudinal direction.

1. A wiper blade for windows, in particular of motor vehicles, comprising:a long, rubber-elastic wiper strip (14) that can be placed against the window (22), wherein said wiper strip is situated parallel to a longitudinal axis on a long, spring-elastic carrier element (12) to which a component (16)
1. A wiper blade for windows, in particular of motor vehicles, comprising:a long, rubber-elastic wiper strip (14) that can be placed against the window (22), wherein said wiper strip is situated parallel to a longitudinal axis on a long, spring-elastic carrier element (12) to which a component (16) belonging to a device for attaching the wiper blade (10) to a driven wiper arm (18) is directly connected, wherein the carrier element (12) has springs (28, 30) designed in the shape of a strap having top and bottom surfaces and lying in front of the window (22) in a plane that is substantially parallel to the window, wherein the bottom surfaces of the straps (13) of which face the window, wherein inner, adjacent longitudinal edges (32) of the springs situated at a distance from each other plunge individually into longitudinal grooves (54, 56) assigned to each longitudinal edge and open toward the longitudinal side of the wiper strip, and are connected to each other by way of a least two transverse ribs (37) situated in the longitudinal direction with distance between them, wherein at least one transverse rib (36) has a center section (42) that extends at a distance from the top strap surfaces (11) of the springs (28, 30) so that at least one bridge-like transverse rib results, whereby the distance (34) between the two springs in particular is less then a bridge width (46), wherein means of attachment (74, 76, 78 and 174, 175, 176, 177, 178) for securing the wiper strip to the carrier element in the longitudinal direction are disposed as one-piece on one of the transverse ribs, wherein the means of attaching are situated on a transverse rib (36) located in the region of one end section of the two springs (28, 30), and wherein the means of attachment comprise an extension (74 and 174) designed in the shape of a tongue that extends from the center section (42) of one transverse rib (36) toward the other end section of the two springs. 2. The wiper blade according to claim 1, wherein the means of attachment (74, 76, 78 and 174, 175, 176, 177, 178) can be brought into their securing position after the wiper strip (14) is positioned on the carrier element (12).3. The wiper blade according to claim 1, wherein the extension (74 and 174) designed in the shape of a tongue grips a cover strip (62) of the wiper strip (14) with fixing means (78 and 177, 178) located above the two longitudinal grooves (54, 56) as well as above the top strap surfaces (11) of the springs (28, 30).4. The wiper blade according to claim 1, wherein the extension designed in the shape of a tongue has at least one projection pointing toward a cover strip (62) of the wiper strip (14) as a fixing means.5. The wiper blade according to claim 4, wherein the projection (76) is designed in the shape of a bezel on its free end.6. The wiper blade according to claim 4, wherein multiple projections (175, 176) pointing toward the cover strip (62) are situated on the extension (174) designed in the shape of a tongue as fixing means.7. The wiper blade according to claim 1, wherein the transverse ribs (36) as well as the extension (74 and 174) designed in the shape of a tongue and connected with one of the transverse ribs as a single part are made out of metal.
