The invention claimed is: 1. A wiper blade (10) with a band-like, elongated, spring elastic single or multipart supporting element (12) that has a longitudinal axis and that, in an unstressed state, is curved in the longitudinal direction and has a connection device (18) arranged in a central portion of a convex, top band side (16) of the supporting element, the connection device butting against the top band side and being intended for releasable connection to a driven wiper arm (20), and an elongate, elastomeric wiper strip (24) arranged on a concave, bottom band side (22) of the supporting element, the wiper strip extending parallel to the longitudinal axis of the supporting element (12) and comprising a folding wedge (38) and a wiper-strip back (34), which are connected to one another via a tilting web (36), characterized in that additional webs (42) are arranged laterally in respect of the tilting web (36), in a longitudinal groove (40), and the additional webs, starting from the tilting web (36), extend perpendicularly to the tilting web to an open side of the longitudinal groove (40), have outer sides (50) reaching at least as far as one of an outer edge (44) of the wiper-strip back (34) or an outer edge (46) of the folding wedge (38), and connect the wiper-strip back (34) to the folding wedge (38). 2. The wiper blade (1) as claimed in claim 1, wherein the tilting web has opposite sides, and characterized in that the additional webs (42) are arranged on both sides of the tilting web (36). 3. The wiper blade (10) as claimed in claim 2, characterized in that the additional webs (42) are located opposite one another on the opposite sides. 4. The wiper blade (10) as claimed in claim 3, characterized in that a spacing (a) between the additional webs (42) is between 10 mm and 50 mm. 5. The wiper blade (10) as claimed in claim 4, characterized in that a thickness (d) of the additional webs (42) is smaller than a thickness (D) of the tilting web (36). 6. The wiper blade (10) as claimed in claim 5, characterized in that the additional webs (42) connect the outer edge (44) of the wiper-strip back (34) and the outer edge (46) of the folding wedge (38) in a straight line (45). 7. The wiper blade (10) as claimed in claim 5, characterized in that outwardly oriented end sides of the additional webs (42) each form a concave profile (48) by means of which the adjacent outer edges (44, 46) of the wiper-strip back (34) and of the folding wedge (38) are connected to one another. 8. The wiper blade (10) as claimed in claim 5, characterized in that the outer sides (50) of the additional webs (42) run diagonally inward in the direction of the tilting web (36) from the outer edge (44) of the wiper-strip back (34) or from the outer edge (46) of the folding wedge (38). 9. The wiper blade (10) as claimed in claim 8, characterized in that slopes of the outer sides (50) of successive additional webs (42) run inward in the direction of the tilting web (36) in an alternating manner from the outer edge (44) of the wiper strip back (34) and from the outer edge (46) of the folding wedge (38). 10. The wiper blade (10) as claimed in claim 2, characterized in that the additional webs (42) on one side are offset in the longitudinal direction in relation to the additional webs (42) on the other side. 11. The wiper blade (10) as claimed in claim 10, characterized in that a spacing (a) between the additional webs (42) is between 10 mm and 50 mm. 12. The wiper blade (10) as claimed in claim 11, characterized in that a thickness (d) of the additional webs (42) is smaller than a thickness (D) of the tilting web (36). 13. The wiper blade (10) as claimed in claim 12, characterized in that the additional webs (42) connect the outer edge (44) of the wiper-strip back (34) and the outer edge (46) of the folding wedge (38) in a straight line (45). 14. The wiper blade (10) as claimed in claim 12, characterized in that outwardly oriented end sides of the additional webs (42) each form a concave profile (48) by means of which the adjacent outer edges (44, 46) of the wiper-strip back (34) and of the folding wedge (38) are connected to one another. 15. The wiper blade (10) as claimed in claim 12, characterized in that the outer sides (50) of the additional webs (42) run diagonally inward in the direction of the tilting web (36) from the outer edge (44) of the wiper-strip back (34) or from the outer edge (46) of the folding wedge (38). 16. The wiper blade (10) as claimed in claim 15, characterized in that slopes of the outer sides (50) of successive additional webs (42) run inward in the direction of the tilting web (36) in an alternating manner from the outer edge (44) of the wiper strip back (34) and from the outer edge (46) of the folding wedge (38). 17. The wiper blade (10) as claimed in claim 1, characterized in that a spacing (a) between the additional webs (42) is between 10 mm and 50 mm. 18. The wiper blade (10) as claimed in claim 1, characterized in that a thickness (d) of the additional webs (42) is smaller than a thickness (D) of the tilting web (36). 19. The wiper blade (10) as claimed in claim 1, characterized in that the additional webs (42) connect the outer edge (44) of the wiper-strip back (34) and the outer edge (46) of the folding wedge (38) in a straight line (45). 20. The wiper blade (10) as claimed in claim 1, characterized in that outwardly oriented end sides of the additional webs (42) each form a concave profile (48) by means of which the adjacent outer edges (44, 46) of the wiper-strip back (34) and of the folding wedge (38) are connected to one another. 21. The wiper blade (10) as claimed in claim 1, characterized in that the outer sides (50) of the additional webs (42) run diagonally inward in the direction of the tilting web (36) from the outer edge (44) of the wiper-strip back (34) or from the outer edge (46) of the folding wedge (38). 22. The wiper blade (10) as claimed in claim 21, characterized in that slopes of the outer sides (50) of successive additional webs (42) run inward in the direction of the tilting web (36) in an alternating manner from the outer edge (44) of the wiper strip back (34) and from the outer edge (46) of the folding wedge (38).
