Abstract

In the case of a wiper device for cleaning glass panes on vehicles, in particular automobiles, the wiper strip (2), which consists of an elastomeric material, is furnished with a molded spoiler (15) on a wiper strip upper side (14). The molded spoiler extends only in a wiper arm area (1″) which lies between one end of the wiper blade (1) and means of attachment (11) to attach the wiper blade (1) to an arm of a windshield wiper.

Claims

1. Wiper device for cleaning glass surfaces in vehicles, specifically automobiles, having a wiper blade-wiper arm array with a wiper blade (1, 102) with an elongate wiper strip (2, 105) consisting of an elastomeric material which, with a wiper strip underside or at least with a wiper lip (7, 108) furnished on the wiper strip underside, can be placed in contact with the specific glass surface and on whose upper side a spoiler (15, 110) is formed and is provided on both of its longitudinal sides (8, 9, 112, 113) with opposingly located longitudinal grooves (10) which are each engaged by preferably flexible support strips (3, 106) extending in the longitudinal direction (L) of the wiper strip (2, 105), as well as with means (11) to attach the wiper blade (1, 102) to a wiper arm (103) which is part of the wiper device, and with a wiper arm (103) which is connectable or is connected to a wiper blade (1, 102) in an area formed for the junction (104) between the ends of the wiper blade (1, 102), where one wiper blade end (102″

) is proximate to the wiper arm and the other wiper blade end (102′

) is distal to the wiper arm (103), characterized in that the molded spoiler (16, 110) extends only in an area (1″

, 109′

) of the wiper blade lying between the attaching means (11) and one end of the wiper blade (1, 102).

2. Wiper device in accordance with claim 1, wherein the spoiler (15, 110) has a changing height (h) in the longitudinal direction (L) of the wiper blade by which the spoiler (15, 110) or an edge of spoiler (16, 16a, 111) projects beyond the plane of an underside of the wiper strip (2, 105).

3. Wiper device in accordance with claim 2, wherein the height of the spoiler (15, 110) decreases toward the one end (102′

) of the wiper blade (1, 102) or the wiper strip (2, 105).

4. Wiper device in accordance with claim 1, wherein the spoiler (15, 110) possesses a constant or essentially constant height (h).

5. Wiper device in accordance with one of the preceding claims, where the spoiler molded on the wiper strip forms a first spoiler surface (15, 110), wherein the wiper arm (103) has an outer cross-section having at least one second spoiler surface (114) at least over an intermediate length.

6. Wiper device in accordance with claim 5, wherein the second spoiler surface (114) forms the continuation of the first spoiler surface (15, 110).

7. Wiper device in accordance with claim 5 or 6, wherein the wiper arm (103) overlaps the wiper blade (1, 102) over an intermediate length between the one end of the wiper blade (102′

) and the area of the junction (11, 104).

8. Wiper device in accordance with one of the preceding claims 5 to 7, wherein the first surface of the spoiler (16, 110) extends over the entire, or almost the entire intermediate length of the wiper blade (1, 102) between the area of the junction (11, 104)and the other end of the wiper blade (102′

).

9. Wiper device in accordance with one of the preceding claims 5 to 8, wherein the first surface of the spoiler (15, 110) emanates from a first edge of the spoiler (16, 111) and wherein the first edge of the spoiler (16, 111) has a changing height in the longitudinal direction of the wiper blade (1, 102).

10. Wiper device in accordance with claim 9, wherein the height of the first edge of the spoiler (16, 111) rises from the other end of the wiper blade (102′

) toward the area of the junction (11, 104).

11. Wiper device in accordance with one of the preceding claims 5 to 10, wherein the first edge of the spoiler (16, 16a, 111) and the second edge of the spoiler (115) each has the same height at the area of the junction (11, 104).

12. Wiper device in accordance with one of the preceding claims 5 to 11, wherein the wiper arm (103) engages a profiled section (109′

) of the wiper strip 105 in the area of the junction (104)from above, preferably straddles it from above.

13. Wiper device in accordance with one of the preceding claims 5 to 12, wherein the wiper arm (103) is formed from a profile which is open toward the underside of the wiper blade (1, 102) or of the wiper strip (2, 105) respectively.

14. Wiper device in accordance with one of the preceding claims 5 to 13, wherein the wiper strip (2, 105) over an intermediate length (1″

) between the one end of the wiper blade (102″

) and the area of the junction (104) has a lower height and/or width than over the intermediate length (1′

) between the area of the junction (104) and the other end of the wiper blade (102′

).

15. Wiper device in accordance with one of the preceding claims 5 to 14, wherein at least the wiper blade (102) over an intermediate length, preferably at least over a part of the length between the area of the junction (104) and the other end of the wiper blade (102′

) on a longitudinal side (112) proximal to the edge of the spoiler (111), has a concave curvature and/or on an additional longitudinal side (113) opposite to this longitudinal side has a convex curvature.
