摘要： In a method for producing flat-blade windshield wipers with curved flat blades in particular, and for obtaining dimensionally stable bending radii with exact tolerances, a spring band formed by flat blades individually arranged one next to the other, is bent between three support sites spaced from each other in the longitudinal direction of the spring band and resting successively in an alternating manner on one of the two sides of the spring band, and the spring band is thereafter re-bent on a subsequent support site in the opposite direction by a re-bending degree lower than the bending degree. The flat blade so treated is subsequently separated from the spring band, combined with a rubber-elastic wiping strip, and provided with a connecting device for a wiper arm.

摘要： The invention relates to a method for producing a bandlike-elongated, spring-elastic element (12) for supporting a rubber-elastic wiper strip (22) of a windshield wiper for vehicles, which element has two spring rails (26, 28), located with a spacing (24) from one another and essentially parallel to one another, which at least on both of their end portions are solidly joined together by transverse ribs (30) that are disposed on the one band face (14) of the spring rails and that span the spacing (24). An especially advantageous production method for such a support element is obtained in that the prefabricated spring rails (26, 28) are solidly joined together in pairs and oriented essentially parallel to one another by means of at least one bandlike retaining element (44) oriented transversely to the spring rails; that the gridlike combination (54) thus obtained is subjected to at least one further method step, by which, by cutting the retaining element (44) between the applicable pairs of spring rails (26, 28), the support elements (12) are released from the combination (54).

摘要： A wiper blade is proposed, which is for cleaning for windows, particularly of motor vehicles. The wiper blade (10) has an elongated, rubber-elastic wiper strip (14), which can be placed against the window (22) and is connected to an elongated, spring-elastic support element (12) so that their longitudinal axes are parallel, which support element (12) is directly connected to a device (16) for connecting the wiper blade to a driven wiper arm (18). The support element (12) has two band-like spring strips (28, 30), which are situated in a plane that is disposed in front of the window, essentially parallel to the window, and whose one, lower band surfaces (13) are oriented toward the window and whose adjacent, inner longitudinal edges (48), which are disposed spaced a distance (34) apart from each other, each protrude into a respective longitudinal groove (54, 56, or 106), which grooves are associated with each longitudinal edge and are open toward a respective longitudinal side of the wiper strip (14), and these two spring strips (36, 38) are connected to each other by at least two crosspieces (36, 38) disposed spaced apart from each other in the longitudinal direction. Manufacturing advantages for the wiper blade according to the invention are achieved if each crosspiece (36, 38) has a middle section (42) which extends spaced a distance (44) apart from the upper band surfaces (11) of the spring strips (28, 30), producing bridge-like crosspieces, where the distance (34) between the two longitudinal strips (28, 30) is less than the bridge width (46).

摘要： A wiper blade is proposed, which is used for cleaning windows, particularly of motor vehicles. The wiper blade (10) has an elongated, rubber-elastic wiper strip (14), which can be placed against the window (22) and is connected in a longitudinally parallel fashion to an elongated, spring-elastic support element (12), which has a connecting device (16) for a wiper arm (18). The wiper blade has two band-like spring strips (28, 30), which are parallel to each other and are disposed in a plane spaced a distance (26) apart from the window (22) and whose one, inner longitudinal edges (32) disposed close to each other are spaced a distance (34) apart from each other, and the wiper strip, which has a uniform cross section over its longitudinal span, has a strip-like wiper lip (102), which can be placed against the window and which, by means of a narrow intermediary strip (102) that is formed by opposing groove-like constrictions (106), is connected to a covering strip (104) secured to the support element (12), and the spring strips secure the wiper strip. A wiper blade, which is particularly low-profile and therefore insensitive to the flow conditions of the window, is obtained if each of the two inner longitudinal edges (32) of the spring strips (28, 30) is disposed in one of the two groove-like constrictions (106) of the wiper strip (100), where the width of the constriction grooves (106), at least over an outer partial region, is greater than the thickness of the spring strips (28, 30).
