A wiper blade to clean windshields, in particular of automobiles. The wiper blade (10) has an elongated belt-shaped, flexible spring support element (12), with a separate first component designed as an elastic rubber wiper strip (14) that can be pressed against the windshield (20) located at the bottom belt surface (13) of the support element and with a separate second component located at the other upper belt surface (11) of the support element (12) that is designed as a wind deflection strip (24) that extends at least along a longitudinal section of the wiper blade (10). A particularly low-disruption wiper blade results if the two components (14, 24) are connected together at their sides facing one another.

What is claimed is: 1. A wiper blade to clean windshields, provided with an elongated belt-shaped, flexible spring support element, with a separate first component designed as an elastic rubber wiper strip that can be pressed against the windshield located at a bottom belt surface of the support element and with a separate second component located at an upper belt surface of the support element that is designed as a wind deflection strip that extends at least along a longitudinal section of the wiper blade, characterized in that the two components are connected together at their sides facing one another, and characterized in that the wind deflection strip has two diverging sides as seen in cross section that are connected together at a common base, the free ends of said sides that face the support element being supported off of the wiper blade, that at the inner wall of one of the two sides is one of a positive and a negative profile shape, and a portion of the wiper strip defines the other of the positive and the negative profile shape, the positive profile shape mating with the negative profile shape, and wherein the wind deflection strip extends along at least half of a length of the wiper blade. 2. A wiper blade according to claim 1, characterized in that the positive profile shape is circular in cross section and is connected to one side of the wind deflection strip via a narrow longitudinal stem, and that the negative profile shape is designed as a circular longitudinal notch in cross section that on its side facing the wind deflection strip is provided a slotted longitudinal opening matched to the thickness of the longitudinal stem. 3. A wiper blade according to claim 2, characterized in that the diameter of the positive profile shape is snugly matched to the diameter of the negative profile shape. 4. A wiper blade according to claim 2, characterized in that the diameter of the positive profile shape that is made of an elastic material is smaller than the diameter of the negative profile shape, that the positive profile shape is provided with a longitudinal hole, and that a bar is introduced into this longitudinal hole that expands the diameter of the positive profile shape to the diameter of the negative profile shape. 5. A wiper blade according to claim 1, wherein the wind deflection strip extends along an entire length of the wiper blade. 6. A wiper blade according to claim 1, wherein the wind deflection strip extends along a substantial portion of a length of the wiper blade. 7. A wiper blade according to claim 1, wherein the wiper strip includes the negative profile shape. 8. A wiper blade to clean windshields, provided with an elongated belt-shaped, flexible spring support element having top and bottom belt surfaces, with a separate first component designed as an elastic rubber wiper strip that can be pressed against the windshield located at the bottom belt surface of the support element and with a separate second component located at the top belt surface of the support element that is designed as a wind deflection strip that extends at least along a longitudinal section of the wiper blade, characterized in that the two components are connected together at their sides facing one another, and characterized in that the wind deflection strip has two diverging sides as seen in cross section that are connected together at a common base, the free ends of said sides that face the support element being supported off of the wiper blade, wherein the inner wall of one of the two sides includes one of a positive and a negative profile shape and the wiper strip includes the other of the positive and negative profile shape, wherein the positive and negative profiles shapes snugly match, and wherein the wind deflection strip extends along at least half of a length of the wiper blade. 9. A wiper blade according to claim 8, characterized in that the positive profile shape is circular in cross section and is connected to one side of the wind deflection strip via a narrow longitudinal stem, and that the negative profile shape is designed as a circular longitudinal notch in cross section that on its side facing the wind deflection strip is provided a slotted longitudinal opening matched to the thickness of the longitudinal stem. 10. A wiper blade according to claim 9, characterized in that the diameter of the positive profile shape is snugly matched to the diameter of the negative profile shape. 11. A wiper blade according to claim 9, characterized in that the diameter of the positive profile shape that is made of an elastic material is smaller than the diameter of the negative profile shape, that the positive profile shape is provided with a longitudinal hole, and that a bar is introduced into this longitudinal hole that expands the diameter of the positive profile shape to the diameter of the negative profile shape. 12. A wiper blade according to claim 8, wherein the wind deflection strip extends along an entire length of the wiper blade. 13. A wiper blade according to claim 8, wherein the wind deflection strip extends along a substantial portion of a length of the wiper blade. 14. A wiper blade according to claim 8, wherein the wiper strip includes the negative profile shape. 15. A windshield wiper blade comprising an elongated belt-shaped, flexible spring support element having top and bottom surfaces and having a longitudinal slot, a wind deflection strip that is located above the top surface of the support element and that extends at least along a longitudinal section of the wiper blade, wherein the wind deflection strip extends along at least half of a length of the wiper blade, and an elastic rubber wiper strip that can be pressed against a windshield and that is located below the bottom surface of the support element, the wiper strip having a narrow portion extending through the slot of the support element, the wiper strip also having a wider portion connected to the narrow portion, the wider portion facing the top surface of the support element, wherein one of the wiper strip and the wind deflection strip has therein a recess, and the other the wiper strip and the wind deflection strip has thereon a projection received in the recess for securing the wind deflection strip to the wiper strip and the support element, and wherein the projection has a cross-sectional shape defining at least a portion of a circle, and wherein the recess is a longitudinal notch that is complementary in cross section. 16. A wiper blade according to claim 15, wherein the projection is generally circular in cross section, and wherein the recess is a longitudinal notch that is generally circular in cross section. 17. A wiper blade according to claim 15, wherein the projection is sized to snugly fit in the notch. 18. A wiper blade according to claim 17, wherein the projection is on the wind deflection strip and the recess is in the wiper strip. 19. A wiper blade according to claim 15, wherein the wind deflection strip extends along an entire length of the wiper blade. 20. A wiper blade according to claim 15, wherein the wind deflection strip extends along a substantial portion of a length of the wiper blade.
