Abstract

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.

Claims

1. 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, wherein the support element has two flexible rails at a distance from one another, wherein the two flexible rails form a longitudinal slot remaining between the two flexible rails, wherein a separate third component extends between the two flexible rails through the longitudinal slot, wherein the first component and second component are connected together by the third component.

2. The wiper blade according to claim 1, wherein the third component has a first continuation that extends on the side of the support element having the lower belt surface, and wherein the third component has a second continuation that extends on the side of the support element having the upper belt surface.

3. The wiper blade according to claim 2, wherein the connection of the second component and the third component is achieved at the second continuation.

4. The wiper blade according to claim 3, wherein the connection of the first component and the third component is achieved at the first continuation.

5. The wiper blade according to claim 4, wherein the first continuation has a first profile shape, as seen in cross section, that matches a mating profile shape of the first component as seen in cross section, and wherein the second continuation has a second profile shape, as seen in cross section, that matches a mating profile shape of the second component as seen in cross section.

6. The wiper blade according to claim 5, wherein the first profile shapes has a first transverse width, wherein the second profile shape has a second transverse width, wherein the longitudinal slot has a transverse width, and wherein the first and second transverse widths are greater than the transverse width of the longitudinal slot.

7. The wiper blade according to claim 1, wherein the second component extends along an entire length of the wiper blade.

8. The wiper blade according to claim 1, wherein the second component extends along a substantial portion of a length of the wiper blade.

9. The wiper blade according to claim 1, wherein the second component extends along at least half of a length of the wiper blade.

10. The wiper blade according to claim 1, wherein the third component is one-piece.

11. A wiper blade to clean windshields, comprising:

an elongated belt-shaped, flexible spring support element having top and bottom belt surfaces;

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;

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;

a connection means for connecting the first component to the second component;

wherein the support element has two flexible rails at a distance from one another, wherein the two flexible rails form a longitudinal slot remaining between the two flexible rails;

wherein the connection means is a third component separate from the first and second components, and wherein the connection means extends between the two flexible rails through the longitudinal slot.

12. The wiper blade according to claim 11, wherein the second component extends along an entire length of the wiper blade.

13. The wiper blade according to claim 11, wherein the second component extends along a substantial portion of a length of the wiper blade.

14. The wiper blade according to claim 11, wherein the second component extends along at least half of a length of the wiper blade.

15. The wiper blade according to claim 11, wherein the connection means is one-piece.

16. The wiper blade according to claim 11, wherein the connection means has a first continuation that extends on the side of the support element having the lower belt surface, and wherein the connection means has a second continuation that extends on the side of the support element having the upper belt surface.

17. The wiper blade according to claim 16, wherein the first continuation has a first profile shape, as seen in cross section, that matches a mating profile shape of the first component as seen in cross section, and wherein the second continuation has a second profile shape, as seen in cross section, that matches a mating profile shape of the second component as seen in cross section.
