Abstract

A windshield wiper has a wiper arm, a wiper blade connected to the wiper arm pivotably about a transverse axis, a device secured to the wiper arm and laterally guiding the wiper blade with a spacing from the transverse axis, the device having a first guide element and also a second guide element which laterally guides the first guide element enabling a spacing between the first guide element and the wiper arm perpendicular to a windshield to vary independently of the wiper arm, the first guiding element connecting the device so that the first guiding element is guided rigidly relative to a direction of motion of the windshield wiper.

Claims

1. A windshield wiper, comprising a wiper arm;

a wiper blade connected to said wiper arm pivotably about a transverse axis;

a device secured to said wiper arm and laterally guiding said wiper blade with a spacing from said transverse axis and preventing a rotation of said wiper blade in a plane parallel to a windshield, said device having a first guide element and also a second guide element which laterally guides said first guide element enabling a spacing between said first guide element and said wiper arm perpendicular to the windshield to vary independently of said wiper arm, said first guide element being guided rigidly relative to a direction of motion of the windshield wiper, wherein said second guide element being a spring tongue which is firmly connected by one end to said first guide element and by another end is secured to said wiper arm.

2. A windshield wiper as defined in claim 1, wherein said second guide element has at least one guide cheek cooperating with said first guide element.

3. A windshield wiper as defined in claim 1, wherein said device is a plastic injection-molded part.

4. A windshield wiper as defined in claim 1, and further comprising a wiper rod on which said device is retained.

5. A windshield wiper as defined in claim 1, and further comprising a link element on which said device is retained.

6. A windshield wiper, comprising a wiper arm;

a wiper blade connected to said wiper arm pivotably about a transverse axis;

a device secured to said wiper arm and laterally guiding said wiper blade with a spacing from said transverse axis and preventing a rotation of said wiper blade in a plane parallel to a windshield, said device having a first guide element and also a second guide element which laterally guides said first guide element enabling a spacing between said first guide element and said wiper arm perpendicular to the windshield to vary independently of said wiper arm, said first guide element being guided rigidly relative to a direction of motion of the windshield wiper, said first guide element being U-shaped.
