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).

1. A wiper blade (10) for windows, comprising:an elongated, rubber-elastic wiper strip (14), wherein said wiper strip can be placed against the window (22); an elongated, spring-elastic support element, wherein said wiper strip is connected in a longitudinally parallel fashion to the elongated, spring-elastic support element (12), wherein the elongated, spring elastic support element has a connecting device (16) for a wiper arm (18) and 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 wherein inner longitudinal edges (32) of the two band-like spring strips 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 (101), wherein the wiper lip can be placed against the window and wherein the wiper lip is connected to a covering strip (104) secured to the support element (12) by means of a narrow intermediary strip (102) that is formed by opposing groove-like constrictions (106), and wherein the spring strips secure the wiper strip, wherein 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), wherein 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), wherein the two spring strips (28, 30) are connected to each other by at least two crosspieces (36, 38) disposed at their end sections, and wherein each crosspiece has a middle section (42), which extends spaced a distance (44) apart from the upper band surface (11) of the spring strips, thus producing bridge-like crosspieces, wherein the distance (34) between the two longitudinal spring strips (28, 30) is less than the bridge width (46), and wherein each crosspiece (36, 38) disposed at the end sections of the two spring strips (28, 30) is provided with a covering cap (82) made of plastic. 2. The wiper blade according to claim 1, wherein the lateral defining surface (108, 110) of the groove-like constrictions (106) diverge from the intermediary strip (102) to the longitudinal sides of the wiper strip (100).3. The wiper blade according to claim 2, wherein one lateral defining surface (110) of the groove-like constrictions (106) has a spherical course, viewed in cross section.4. The wiper blade according to claim 2, wherein both lateral defining surfaces (108,110) of the groove-like constrictions (106) have a spherical course, viewed in cross section.5. The wiper blade according to claim 1, wherein the wiper lip (101) is provided with a completely closed longitudinal conduit (118).6. The wiper blade according to claim 1, wherein an air gap remains between the respective opposing longitudinal edges (32) of the spring strips (28, 30) and the respectively adjacent longitudinal sides of the intermediary strip (102).7. The wiper blade according to claim 1, wherein each spring strip (28, 30), at least with a central edge strip, protrudes from its groove-like constriction (106).8. The wiper blade according to claim 1, wherein the two spring strips (28, 30) are embodied as separate components.9. The wiper blade according to claim 8, wherein the crosspieces (36, 38) are embodied as separate components and are affixed to the two spring strips (28,30).10.
