Abstract

This invention relates to a wiper blade (20) having a connecting part (32) which is mounted on a carrying element (24) of the wiper blade (20) and has a pivot pin (42, 96, 106, 138, 146, 164, 178) of a joint (30) whose free end is connected to a wiper rod (28, 70, 80, 90, 118, 136, 150). It is proposed that the joint (30) includes a cap (54, 114, 128, 160, 190) which covers the connecting part (32) and is attached to it, and during operation the wiper blade (20) and the wiper rod (28, 70, 80, 90, 118, 136, 150) are secured in the installed position.

Claims

1. Wiper blade (20) with a connecting part (32) which is mounted on a carrying element (24) of the wiper blade (20) and has a pivot pin (178) of a joint (30) whose free end is connected to a wiper rod (28, 90), characterized in that the joint (30) includes a cap (190) which covers and is attached to the connecting part (32) and in an installed position it secures the wiper blade (20) and the wiper rod (28, 90) during operation, characterized in that the cap (190) has at least one pocket facing the wiper rod (28, 90), said at least one pocket being open toward the windshield, and characterized in that the pivot pin (178) has two diametrically opposed wings (180, 182) extending radially to the pivot pin (178) and in the longitudinal direction of the wiper blade (28, 90) and engaging in the installed state in correspondingly aligned lateral pockets (184, 186) of the cap (190) in the manner of a bayonet closure.

2. Wiper blade (20) according to claim 1, characterized in that a spoiler (26) is attached to the carrying element (24) in the longitudinal direction on both sides of the connecting part (32), the cap (190) being connected to a portion of the spoiler with a connecting profile (64).

3. Wiper blade (20) according to claim 2, characterized in that an oncoming flow side of the spoiler (26) is facing the wiper rod (28).

4. Wiper blade (20) according to claim 1, characterized in that the pivot pin (178) is rotatably mounted in the connecting part (34), which is designed as a sheet metal claw (32) and is attached to the carrying element (24) by means of catch noses (36) mounted laterally on its back (34).

5. Wiper blade (20) according to claim 4, characterized in that the sheet metal claw (32) has side faces (38) standing upward on its longitudinal sides (66), said faces being connected by a bearing tube (40) in which the pivot pin (178) is rotatably mounted.

6. Wiper blade (20) according to claim 5, characterized in that the cap (190) has a clip (58) in the area of the bearing tube (42) with which it is attached to the bearing tube (40) or the pivot pin (178).

7. Wiper blade (20) according to claim 5, characterized in that the pivot pin (190) protrudes on one end beyond a side face (38) of the sheet metal claw (32) and is attached to the wiper rod (28,90) in a rotationally fixed manner, while its other end protrudes slightly beyond the respective side face (38) and engages in a recess in the cap (190).

8. Wiper blade (20) according to claim 4, characterized in that the cap (190) is held on the sheet metal claw (32) by means of catch noses (56), which engage in catch recesses (104) in the side faces (38) of the sheet metal claw (32).

9. Wiper blade (20) according to claim 1, characterized in that the pivot pin (178) has a head (44) in the direction of the wiper rod (28), said head having a slot (46) to accommodate the wiper rod (28) which is secured in the slot (46) by means of a cross pin (48).

10. Wiper blade (20) according to claim 1, characterized in that the wiper rod (90) is rotated by approximately 90°

about its longitudinal axis at its end which faces the pivot pin (96) so that its broad side runs across the pivot pin (96).
