Abstract

The invention relates to an articulated wiper arm of a wiper apparatus for windows of motor vehicles with a device for a detachable connection to a pivoted wiper blade on one free end, in particular for connection to a non-articulated wiper blade, which includes at least one articulated bolt.

It is planned that the device for connection to the wiper blade (16) is embodied as a single piece with the wiper arm (10).

Claims

1. Articulated wiper arm of a wiper apparatus for windows of motor vehicles, having a free end and a non-free end opposite the free end, the free end of the articulated wiper arm being a single, substantially flat layer of material and having a device for detachably and pivotably connecting to a wiper blade, in particular for connecting to a non-articulated wiper blade, the device for connecting to the wiper blade being fixed to the wiper arm and comprising

an articulating bolt for pivotably carrying the wiper blade, and

a safety hook for partially gripping around the wiper blade in an operating position thereof,

wherein the safety hook is a bent section of the single layer defining the free end of the wiper arm, and extending to a terminus of the wiper arm, and the articulating bolt is located between the safety hook and the non-free end of the articulated wiper arm;

and

wherein the articulating bolt extends from the single layer of the wiper arm.

2. A wiper arm according to claim 1 wherein the articulating bolt is glued, welded or pressed to the wiper arm.

3. A wiper arm according to claim 1 wherein the wiper arm is formed of a flat material that is twisted around its longitudinal axis in sections.

5. A wiper arm according to claim 1 wherein the free end with the articulating bolt is twisted around its longitudinal axis by approximately 90 degrees vis-à

-vis a carrying area near a swivel support of the wiper arm.

6. A wiper arm according to claim 1 wherein a connecting section between a carrying area and the free end has a longitudinal axis and is twisted vis-à

-vis the carrying area and the free end and around the longitudinal axis by an angle of between 0 degrees and 90 degrees.

7. A wiper arm according to claim 1 wherein a connecting section between a carrying area and the free end has a longitudinal axis and is twisted vis-à

-vis the carrying area and the free end and around the longitudinal axis by approximately 45 degrees.

8. A wiper arm according to claim 1 wherein in an operating position, the wiper blade is locked on the wiper arm and is restricted in terms of its swivel range vis-à

-vis said wiper arm.

4. A wiper arm according to 1 wherein the free end with the articulating bolt is twisted around its longitudinal axis by an angle between 0 degrees and 90 degrees vis-à

-vis a carrying area near a swivel support of the wiper arm.

9. A windshield wiper assembly comprising:

an articulated wiper arm having a free end the free end being a single, substantially flat layer of material and a non-free end opposite the free end;

a wiper blade; and

a device for detachably and pivotably connecting the wiper arm and the wiper blade, the device being fixed to the wiper arm and including an articulating bolt pivotably carrying the wiper blade, and a safety hook partially gripping around the wiper blade in an operating position thereof, the safety hook being a bent section of the single layer defining the free end of the wiper arm, and extending to a terminus of the wiper arm

wherein the articulating bolt is located between the safety hook and the non-free end of the articulated wiper arm; and

wherein the articulating bolt extends from the single layer of the wiper arm.

10. The assembly of claim 9 wherein the safety hook is longer than the articulating bolt.

11. The assembly of claim 9 wherein the articulating bolt is glued, welded or pressed to the wiper arm.

12. The assembly of claim 9 wherein the wiper arm is formed of a flat material that is twisted around its longitudinal axis in sections.

13. The assembly of claim 9 wherein the free end with the articulating bolt is twisted around its longitudinal axis by an angle between 0 degrees and 90 degrees vis-à

-vis a carrying area near a swivel support of the wiper arm.

14. The assembly of claim 9 wherein the free end with the articulating bolt is twisted around its longitudinal axis by approximately 90 degrees vis-à

-vis a carrying area near a swivel support of the wiper arm.

15. The assembly of claim 9 wherein a connecting section between a carrying area and the free end has a longitudinal axis and is twisted vis-à

-vis the carrying area and the free end and around the longitudinal axis by an angle of between 0 degrees and 90 degrees.

16. The assembly of claim 9 wherein a connecting section between a carrying area and the free end has a longitudinal axis and is twisted vis-à

-vis the carrying area and the free end and around the longitudinal axis by approximately 45 degrees.

17. The assembly of claim 9 wherein in an operating position, the wiper blade is locked on the wiper arm and is restricted in terms of its swivel range vis-à

-vis said wiper arm.
