Abstract

A wiper blade (10) is proposed having a rubber elastic wiper strip (12). The wiper strip (12) is secured by means of at least one spring rail (14, 16) as supporting element. An end cap (20) is attached to at least one end of the longitudinal extension of the supporting element. According to the invention, the end cap (20) has at least one first, energy-absorbing region (22) and one second, in particular stabilizing region (24).

Claims

1. Wiper blade (10) having a rubber-elastic wiper strip (12), which is supported by at least one spring bar (14, 16) as supporting element, and having at least one end cap (20), which is attached to at least one end of the longitudinal extent of the supporting element, characterized in that the end cap (20) comprises at least one first, energy-absorbing area (22) and one second, stabilizing area (24).

2. Wiper blade (10) as claimed in claim 1, characterized in that the first, energy-absorbing area (22) consists of a more flexible material than the second area (24).

3. Wiper blade (10) as claimed in claim 1, characterized in that the wiper strip (12) comprises a wiper lip (18), which extends approximately parallel to the supporting element, and the first area (22) of the end cap (20) is arranged on the same side of the supporting element as the wiper lip (18).

4. Wiper blade (10) as claimed in claim 1, characterized in that the end cap (20) is produced using a multicomponent injection molding method.

5. Wiper blade (10) as claimed in claim 1, characterized in that the first area (22) comprises a thermoplastic elastomer.

6. Wiper blade (10) as claimed in claim 1, characterized in that the second area (24) comprises a connecting means (26, 28) for connecting the end cap (20) to the supporting element and/or the wiper strip (12).

7. Wiper blade (10) as claimed in claim 2, characterized in that the wiper strip (12) comprises a wiper lip (18), which extends approximately parallel to the supporting element, and the first area (22) of the end cap (20) is arranged on the same side of the supporting element as the wiper lip (18).

8. Wiper blade (10) as claimed in claim 7, characterized in that the end cap (20) is produced using a multicomponent injection molding method.

9. Wiper blade (10) as claimed in claim 8, characterized in that the first area (22) comprises a thermoplastic elastomer.

10. Wiper blade (10) as claimed in claim 9, characterized in that the second area (24) comprises a connecting means (26, 28) for connecting the end cap (20) to the supporting element and/or the wiper strip (12).
