Abstract

The invention relates to a display device (38) for a wiper blade (10) made up of a plastic piece with a display field (40, 42, 44) with means (52) for clipping to the wiper blade (10). According to the invention, said device has the same cross-sectional profile as a spoiler (30) for the wiper blade (10) of flat bar construction, wherein the inner profile (50) of the display device (38) matches the outer profile (32, 34, 36) of the spoiler (30).

5. The display device (38) as claimed in claim 2, characterized in that a display field (44) for details of a wiper blade manufacturer is provided on an outflow side (34).

6. The display device (38) as claimed in claim 1, characterized in that a display field (40) for details of a vehicle manufacturer is provided on an inflow side (32).

7. The display device (38) as claimed in claim 2, characterized in that provided on an outflow side (34) is a display field (42) that changes its color as a function of the time loading imposed by influences from weather or environment.

8. The display device (38) as claimed in claim 7, characterized in that the display field (42) includes a basic material or is coated with a basic material that changes color with the time loading imposed by the influences from weather or environment and includes a legend (48) whose color is the same as the initial color of the basic material of the display field (42), but does not change or does so differently from the basic material of the display field (42).

9. The display device (38) as claimed in claim 8, characterized in that a further display field (44) for details of a wiper blade manufacturer is provided on the outflow side (34).

10. The display device (38) as claimed in claim 9, characterized in that a display field (40) for details of a vehicle manufacturer is provided on an inflow side (32).

21. The display device (38) as claimed in claim 1, characterized in that the display device (38) has an inner profile (50) matching the outer profile (32, 34, 36) of the spoiler (30).

22. The display device (38) as claimed in claim 21, characterized in that the spoiler has an inflow side (32) with a curved profile and a generally linear outflow side (34), and in that an inner profile (50) matches the profile of the inflow side (32) and the outflow side (34).

23. The display device (38) as claimed in claim 1, characterized in that the wiper blade (10) has a connecting element (24) operable to connect the wiper blade (10) to a wiper arm, and in that the display device (38) is separate from the connecting element (24).

24. The display device (38) as claimed in claim 1, characterized in that the spoiler (30) has edges (36) engaging spring rails of the wiper blade (10), and in that the display device (38) has claws (52) which clip onto the spoiler (30).

25. The display device (38) as claimed in claim 4, characterized in that the legend (48) is not perceptible in a new state of the basic material as a result of the legend (48) having the same color as the initial color of the basic material.

31. The display device (38) as claimed in claim 1, characterized in that the display device (38) has a uniform cross-section throughout the display field (40).

11. A wiper blade (10) of flat bar construction, comprising a spoiler (30) having an outer profile and a display device (38), the display device including a plastic part with a display field (40, 42, 44), and means (52) for clipping onto the wiper blade (10), characterized in that the display device has a cross-sectional profile the same as that of the spoiler (30), an outer profile of the display device (38) substantially conforming to the outer profile (32, 34, 36) of the spoiler (30), a thickness of the display device (38) being substantially uniform.
