The invention is based on a wiper blade (12) with a wiper strip (14) which has a wiper lip (16) and a head strip (20) which is integrally formed on said wiper lip and, in a first longitudinal channel (26), has a supporting element in the form of a spring rail (18) with a flat cross section, and has
The invention is based on a wiper blade (12) with a wiper strip (14) which has a wiper lip (16) and a head strip (20) which is integrally formed on said wiper lip and, in a first longitudinal channel (26), has a supporting element in the form of a spring rail (18) with a flat cross section, and has a spoiler (22, 38, 46) on that side which faces away from the wiper lip (16). It is proposed that the spoiler (22, 38, 46) surrounds the head strip (20) on its longitudinal sides by means of guide rails (40).

1. A wiper blade (12) with a wiper strip (14) which possesses a wiper lip (16) and a head strip (20) which is integrally formed on the wiper lip and which has in a first longitudinal duct (26) a carrying element in the form of a spring rail (18) of flat cross section and which carries a spoiler (22,
1. A wiper blade (12) with a wiper strip (14) which possesses a wiper lip (16) and a head strip (20) which is integrally formed on the wiper lip and which has in a first longitudinal duct (26) a carrying element in the form of a spring rail (18) of flat cross section and which carries a spoiler (22, 38, 46) on its side facing away from the wiper lip (16), characterized in that the spoiler (22, 38, 46) surrounds the head strip (20) on its longitudinal sides by means of guide rails (30, 40), characterized in that the first longitudinal duct (26) substantially surrounds the spring rail (18), and characterized in that the spoiler (22, 38, 46) possesses, on that side of the head strip (20) which faces away from the wiper lip (16), at least one second longitudinal duct (32, 42) which runs parallel to the first longitudinal duct (26) and which has a substantially identical cross section to the first longitudinal duct (26). 2. The wiper blade (12) as claimed in claim 1, characterized in that the guide rails (40) are extruded on the spoiler (22, 38, 46) and have a higher hardness than the remaining spoiler (22, 38, 46). 3. The wiper blade (12) as claimed in claim 2, characterized in that at least one end piece (48) closed on an end face is integrally formed on the spoiler (46). 4. The wiper blade (12) as claimed in claim 3, characterized in that the second longitudinal duct (32, 42) is connected via a longitudinal gap (44) to a space between the guide rails (40) for receiving the head strip (20). 5. The wiper blade (12) as claimed in claim 4, characterized in that the carrying element comprises a second spring rail (28, 34) positioned in the second longitudinal duct (32, 42) in the spoiler (22, 38, 46). 6. The wiper blade (12) as claimed in claim 5, characterized in that the carrying element (18, 28, 34) has a cross section which varies in its width and/or height over the length of the spring rail (18). 7. The wiper blade (12) as claimed in claim 6, characterized in that the first spring rail (18) possesses a different length, as compared with the second spring rail (28, 34). 8. The wiper blade (12) as claimed in claim 7, characterized in that the cross section of one and/or of both spring rails (18, 28, 34) varies in its width (50) and/or height (52) over their length. 9. The wiper blade (12) as claimed in claim 6 characterized in that the cross section of one and/or of both spring rails (18, 28, 34) varies in its width (50) and/or height (52) over their length. 10. The wiper blade (12) as claimed in claim 5 characterized in that the first spring rail (18) possesses a different length, as compared with the second spring rail (28, 34). 11. The wiper blade (12) as claimed in claim 5 characterized in that the cross section of one and/or of both spring rails (18, 28, 34) varies in its width (50) and/or height (52) over their length. 12. The wiper blade (12) as claimed in claim 1, characterized in that at least one end piece (48) closed on an end face is integrally formed on the spoiler (46). 13. The wiper blade (12) as claimed in claim 1, characterized in that the second longitudinal duct (32, 42) is connected via a longitudinal gap (44) to a space between the guide rails (40) for receiving the head strip (20). 14. The wiper blade (12) as claimed in claim 1, characterized in that the carrying element comprises a second spring rail (28, 34) positioned in the second longitudinal duct (32, 42) in the spoiler (22, 38, 46). 15. The wiper blade (12) as claimed in claim 14, characterized in that the first spring rail (18) possesses a different length, as compared with the second spring rail (28, 34). 16. The wiper blade (12) as claimed in claim 14, characterized in that the cross section of one and/or of both spring rails (18, 28, 34) varies in its width (50) and/or height (52) over their length. 17. The wiper blade (12) as claimed in claim 1, characterized in that the carrying element (18, 28, 34) has a cross section which varies in its width and/or height over the length of the spring rail (18).
