DE202004012549U1 - Windshield wiper arm for e.g. van, has attachment with fastening position for fastening arm, and including wiper that can be suspended and/or is held by clip at fixing position for fixing arm on fixing position - Google Patents

Abstract

The arm has an attachment (5) fastening the arm in a fastening position. The attachment has a wiper that is suspended and/or held by a clip at the fixing position for fixing the arm on the fixing position. The possibility of the suspension of the wiper is realized by guidance within the area of the attachment and an appropriate rising of the wiper within the area of the arm. A bosh unit fixes the arm in its position at the attachment.

Description

The The present invention is concerned with the provision of connectivity a wiper arm, which is characterized by a simple disassembly option distinguished.

State of technology

Of the The prior art knows various methods to attach wiper arms. The most common method is the screwing.

Problem Description

In the arrangement of a linear wiper, as in the German patent application with the file number DE 102004029080.6 , described, the problem could arise that the wiper due to a defect does not go to the parking position, which is located outside the wiping field. In this case, the wiper arm would have to be removed to open the door. This would not be possible without tools with the Wischarmbefestigungen the current state of the art.

task

It results from the problem described the task, a Wiper arm or attachment for To create a wiper arm that is or that is particularly easy to solve.

Solution of the problem

The Problem is solved by a Wischarmbefestigung in which the wiper arm through a profiled or profile-like Form is pushed onto the attachment point of the driver. The wiper arm is then passed through a clip at the attachment point held and so very easily removed by loosening the clip again and removed.

description

An attachment of a windscreen wiper arm ( 1 ), whereby the windscreen wiper arm ( 1 ) at the attachment point on the driver carrying the windscreen wiper ( 5 ), pushed or in the, the wiper-carrying carrier ( 5 ) is inserted. The windscreen wiper arm ( 1 ) is replaced by a detent ( 4 ) by a lever ( 3 ) is operable in the groove ( 2 ) held. The groove ( 2 ) into which the wiper arm ( 1 ) is preferably in the form of a dovetail profile. In such a profiled shape, the wiper arm ( 1 ), which has a shape which is formed in the region of the attachment such that it can be inserted into the groove of the driver, are held approximately automatically by pressing forces. Furthermore, there is a locking element which fixes and holds the windscreen wiper arm in its position on the driver. This locking connection has only a locking, or additional function, since the wiper arm is already held by the pressing forces in the groove of the driver.

These Mounting form is particularly suitable for mounting linear wiper arms on vehicles, such as vans. In these vehicles a disc is wiped, which is installed in a door. Because the wiper in such vehicles on a guide rail above the Door is led, the wiper does not move with the door to be opened, but can block it when opening, if the wiper is still in the area of the disc. The door can therefore only open when the windscreen wiper is in its parking position or if the windscreen wiper arm was previously dismantled.

From the use in linear wiper systems proved particularly advantageous, in which the wiper arm is attached to a driver, the driver is driven by a rope, which in turn via pulleys guided and from a rope drum on which the rope is wound up and which is connected to an electric motor is moved. These Invention can of course also used in all other Linearschscheibenwischersystemen become.

there is according to a preferred embodiment, the direction in the wiper arm is pushed into the fastening groove vertically to the plane of the wiping field (Y-Z-plane) the windscreen wiper, namely in X direction. As a rule, the direction of travel of the vehicle the X direction corresponds. This arrangement prevents inertial forces from passing through the movement of the wiper arm, act in the direction of the mounting groove and possibly loosen the wiper arm can or too much stress on the latching. Forces by the acceleration of the vehicle can arise neglected in this case because at positive accelerations the forces are below a critical point remain and with negative acceleration forces the wiper arms of the rear wiper be on the disc and be held with it.
