Description

The present invention relates to a wiper, in particular a wiper arm, for a wiper device, and a method for producing such a wiper, comprising a fastening part which is intended to be connected to a joint part via a rotary joint.

State of the art

The document DE 103 48 773 A1 discloses a wiper arm mounting portion having a single bushing for a pivot joint.

Disclosure of Invention

The present invention with the features of the main claim has the advantage that at least two sliding bearings for the swivel joint are arranged on the fastening part. On the one hand, this saves material and, on the other hand, creates space for other components, such as a washing water hose. The friction at the swivel joint can also be reduced.

Advantageous developments of the invention according to the main claim are possible due to the features listed in the subclaims. So it is advantageous if the at least two plain bearings are introduced into the fastening part, as a result of which a stable design is made possible.

It is also advantageous if the ends of the at least two plain bearings are flanged, as a result of which the at least two plain bearings can be fixed quickly and stably to the fastening part.

It is also advantageous if at least one bearing pin is introduced into the at least two plain bearings, which is intended to be fastened to the joint part. This enables stable mounting of the bearing pin.

The invention also relates to a method for producing a wiper, in particular a wiper according to the preceding description, for a wiper device, comprising a fastening part which is intended to be connected to a joint part via a rotary joint. The method has the advantage over the cited prior art that at least two plain bearings for the rotary joint are arranged on the fastening part. In this way, a wiper can advantageously be produced in which, on the one hand, material is saved and, on the other hand, there is space for further components, such as a washing water hose. A wiper can also be produced in this way in which the friction at the pivot joint is reduced.

It is also advantageous if the at least two sliding bearings are introduced into the fastening part, as a result of which a stable configuration of the wiper is made possible.

It is also advantageous if the ends of the at least two plain bearings are flanged, as a result of which the at least two plain bearings can be fixed quickly and stably to the fastening part.

It is particularly advantageous if one end of each of the at least two plain bearings is flanged before the at least two plain bearings are introduced into the fastening part, as a result of which the method can be carried out more efficiently.

It is also particularly advantageous if a further end of each of the at least two plain bearings is crimped after the at least two plain bearings have been introduced into the fastening part, as a result of which the method can also be carried out more efficiently.

Description of the embodiment

In 1 A perspective view of one embodiment of a wiper 10 is shown. In the present case, the wiper 10 is a wiper arm 12 for a wiper device, or a windshield wiper device, of a motor vehicle.

The wiper 10 comprises a fastening part 14 and a joint part 16. The wiper also comprises a wiper rod 18 and an adapter 20.

The fastening part 14 is connected to the joint part 16 via a rotary joint 22 . The joint part 16 is connected to the wiper rod 18 which in turn is connected to the adapter 20 is. The adapter 20 is provided for attaching a wiper blade.

In 2 FIG. 14 is a perspective view of an attachment part 14 of the wiper 10 of FIG 1 shown in the area of the pivot joint 22 . The rotary joint 22 comprises two plain bearings 24 arranged on the fastening part 14. The two plain bearings 24 can save material on the one hand and create space for other components, such as a washing water hose, on the other. The friction at the pivot joint 22 can also be reduced.

The two plain bearings 24 are introduced into the fastening part 14 . This enables a stable configuration, in the present case of the swivel joint 22 . In the case shown, the slide bearings 24 are each introduced into an opening 28 provided for the respective slide bearing 24 .

The ends 30 of the at least two plain bearings 24 are flanged. As a result, the slide bearings 24 can be quickly fixed to the fastening part 14, in the present case to the openings 28 of the fastening part 14.

Furthermore, the swivel joint 22 comprises at least one bearing pin 26 which is intended to be attached to the joint part 16 . As in 2 shown, the bearing pin 26 is inserted into the two plain bearings 24 arranged on the fastening part 14 . In the present case, the two plain bearings 24 for the bearing pin 26 are arranged on the fastening part 14 . Correspondingly, in 3 a plan view of the fastening part 14 is shown, with the bearing pin 26 already being introduced into the two slide bearings 24 . In 1 the bearing pin 26 is already attached to the joint part 16.

For the exemplary embodiment shown, the inner end 32 of each of the two plain bearings 24 was crimped in relation to the fastening part 14 before the two plain bearings 24 were introduced into the fastening part 14 . As a result, the plain bearings 24 can be fitted particularly quickly.

Alternatively, however, it would also be conceivable that, in relation to the fastening part 14 , the outer end 34 of each of the two plain bearings 24 is flanged before the two plain bearings 24 are introduced into the fastening part 14 .

For the exemplary embodiment shown, in relation to the fastening part 14 , the outer end 34 of each of the at least two plain bearings 24 was flanged after the two plain bearings 24 had been introduced into the fastening part 14 . As a result, the plain bearings 24 can also be mounted particularly quickly.

Alternatively, however, it would also be conceivable that, in relation to the fastening part 14 , the inner end 32 of each of the two plain bearings 24 is flanged after the two plain bearings 24 have been introduced into the fastening part 14 .

In the case shown, the plain bearings 24 are radial bearings which are provided for the radial bearing of a shaft, in the present case the bearing pin 26 . The two slide bearings 24 can also be regarded as bearing bushes.
