The invention relates to a windscreen wiper apparatus for a motor vehicle, having a wiper motor and having at least one wiper bearing in which a wiper shaft is mounted, it being possible to drive said wiper shaft by means of the wiper motor in order to operate a wiper arm which is connected to the wiper shaft, wherein the wiper bearing has a bearing pin () for holding a tubular support (), it being possible for said bearing pin to be fixed to the tubular support () by means of a crimp, characterized in that the bearing pin () has an outer contour () which is already formed, at least in a region of overlap with the crimp, so as to correspond to an inner contour () of the crimped tubular support (), before the crimp is introduced, and also to a method for producing said windscreen wiper apparatus.

Windshield wiper apparatus

A windshield wiper device () especially for a motor vehicle is proposed. Said device is comprised essentially of a plate-shaped base (), on which a drive unit (), a wiper bearing () and a retaining element () are arranged. In accordance with the invention, the plate-shaped base () is provided with predetermined breaking points ().

Windshield wiping device, especially for a motor vehicle

A windshield wiper device (), particularly for a motor vehicle, is proposed. This windshield wiper device comprises a wiper bearing () supporting a wiper shaft (), which has an undercut () in which a securing device () for axially fixing the wiper shaft () in the wiper bearing () is arranged. The securing device () can be displaced by the effects of a defined axial force component (F) on the wiper shaft (), whereby the wiper shaft () can be displaced in relationship to the wiper bearing (). According to the invention, the securing device () comprises a bushing section () with an indentation (), which engages in the undercut () of the wiper shaft ().

Windscreen wiping device, particularly for a motor vehicle

The invention relates to a windshield wiper device (), in particular for a motor vehicle, comprising a support (), on which a bearing () is arranged, which supports a wiper shaft (). In this case, a retaining element () is provided, which detachably connects the bearing () to the support.

Windscreen wiper device, in particular for a motor vehicle

The present invention relates to a wiper having a wiper arm () and a fastening element (), the fastening element () being fastened on the wiper arm (), and the fastening element () having a hub () which can be plugged onto a drive shaft (). Precision alignment of the wiper relative to the drive shaft () is made possible in that the fastening element () is plugged into a cutout () in the wiper arm () in a form-fitting manner in one of at least two possible alignments. A wiper constructed in this way is, in addition, compact.

Wiper

Windshield wiper device for a motor vehicle with at least one molded tube () to accommodate a drive shaft to drive at least one wiper arm, wherein the at least one molded tube () can be attached to a holding element () that can be connected to the body, and to a stub () accommodating a mounting plate tube, and connecting bridges () are provided to attach the at least one molded tube () to the holding element () and/or to the stub ().

Windshield wiping device for a motor vehicle

Disclosed is a windshield wiper device (), comprising a wiper bearing () which is essentially composed of a molded tube () that can be fastened to a motor vehicle by means of a fastening element (). A wiper shaft () to which a wiper lever can be fastened is positioned in the molded tube (). A predetermined breaking point () is provided on the fastening element () in such a way that the wiper bearing () is able to dip into the interior of the motor vehicle in case a defined and essentially axial force acts on the wiper shaft (). The predetermined breaking point () is embodied as a hole in this case.

Winshield wiping device

The invention starts with a windshield wiper device (), in particular for a motor vehicle, with at least one drive element () that can be fastened to the vehicle body () and that has a driven shaft () and at least two axially rigid fastening elements (), which engage in receiving openings () on the vehicle body () and are provided with at least one damping element () for damping mechanical vibrations. It is proposed that the damping elements () are fastening blocks made of a rubber-elastic material and are fastened to the drive element (), that said damping elements are provided with slots () and are arranged in such a manner that they can be inserted in a first assembly direction () in the receiving openings () and prompted by a movement in a second assembly direction () transverse to the first direction the damping elements reach across the first edge () of the receiving opening () with a slot (), and that a locking element () secures the final position in the second assembly direction ().

Windshield wiper, especially for a motor vehicle

The invention relates to a method for adjusting a wiping angle (&#x3c6;, &#x3c6;) between a park position and a reversal position () of a wiper lever () of a windshield wiper system for a motor vehicle with at least one wiper lever () whose park position or reversal position () runs approximately parallel to an A pillar () of a vehicle body, which laterally delimits a windshield (), wherein the wiping angle (&#x3c6;) is adjusted by means of an eccentric ball pivot (), which is arranged on a free end of a driving crank () and connects the same to a motor crank () in an articulated manner by means of an articulated rod (), while the other end of the driving crank () sits on a drive shaft () in a rotationally fixed manner, said drive shaft driving a fastening part () of the wiper lever (). It is proposed that the windshield wiper system is first mounted on the vehicle body without the eccentric ball pivot (), that a rivet journal () of the eccentric ball pivot () is then inserted into a corresponding bore hole of the driving crank (), that the optimum wiping angle (&#x3c6;) is determined and adjusted by modifying the effective radius () between an articulation axis () of the eccentric ball pivot () and an axis () of the drive shaft () by rotating the eccentric ball pivot () around an axis () of the rivet journal (), and that finally the rivet journal () is fixed in the driving crank () in the adjusted position.

Method for adjusting a wiping angle

The invention is based on a wiper arm ( ) for a windshield wiper comprising a mounting part ( ) and an articulated part ( ) that are connected to each other via a hinged joint ( ) that has a hub ( ) permanently connected with one part ( or ) and open toward the other part ( or ), and an articulated axle ( ) permanently connected with the other part ( or ), wherein one of the ends of a tension spring ( ) is attached to an attachment device ( ) of the articulated part ( ) and the other end is attached to the mounting part ( ), and the hub ( ) and the articulated axle ( ) mutually loaded in the assembled state, and the hinged joint ( ), in a preassembled state of the wiper arm ( ) in a defined transport position, grips a seating surface that is situated on the side of the parts named above opposite to the hub ( ) in relation to the line of force ( ) of the tension spring ( ) and is formed by at least one bearing surface ( ) on the articulated part ( ) and on the mounting part ( ) in each case. It is proposed that the bearing surfaces ( ) are arranged and/or designed in such a fashion that, with a smaller joint angle (&phgr;) beyond the transport position, the articulated axle ( ) moves from its seating surface at the hub ( ) toward the open end ( ) and thereby increases the preload on the tension spring ( ).
