DE10336673A1 - Fastening of windscreen wiper system to motor vehicles uses two plug connection for fastening into holders on vehicle body, to reduce number of fastening points - Google Patents

Abstract

The wiper system is a modular component with several connection points for mounting on the vehicle, with at least one, pref. two, plug connections (1). These are located in the area of the wiper bearings. Each plug connection has a guide stud (2) passing through a long bore in a slider (3), so that this can be moved on the stud via a stop plate (13). A rubber cone (4) is fastened to the slider. The plug connection is inserted into a retainer of a holder (5) on the vehicle body. The holder also acts as fastening point for a screw connection.

Description

The The invention relates to the attachment of a windshield wiper system a motor vehicle according to the preamble of claim 1.

It is known windscreen wiper systems, in particular for motor vehicles, To attach as pre-assembled modules to the motor vehicles. The assembly of a windshield wiper system includes this Mounting tube for attaching the windscreen wiper system to the vehicle body. On the mounting tube are the wiper shafts and bearings and the wiper motor attached, over a coupling linkage connected to the wiper shafts and bearings.

It are also on the mounting tube and possibly on the wiper motor Attachment points provided at which the windshield wiper system with the vehicle body connected, usually bolted. At the attachment points are damping elements between the Vehicle body and the windshield wiper system arranged, for example made of rubber to the transfer to avoid vibrations.

at this known attachment of the windshield wiper system is disadvantageous that the arrangement of Be fastening points in particular in the area the wiper bearing is hampered by the restricted space. For larger windscreen wiper systems are also in about five required six attachment points on the vehicle body, which is relatively high Manual assembly effort leads. The assembly is also difficult, as they are in confined space conditions perform is.

Of the The invention is based on the object, a Attachment for a windscreen wiper system for to create a motor vehicle that has the aforementioned disadvantages avoids and a space-saving attachment of the windshield wiper system enabled with less installation effort.

The Invention solves This object with the characterizing features of claim 1.

The under claims have advantageous developments of the invention the subject.

The inventive attachment a windshield wiper system on a motor vehicle with the claim 1 mentioned characteristic features reduced to advantageous The number of screw points to be mounted on the vehicle body by two arranged at the ends of the mounting tube connectors.

moreover cause the guide pin invention the connectors a prefix the windshield wiper system on the vehicle body, allowing subsequent assembly by screwing the facility on the vehicle is facilitated.

By the arrangement of the rubber cone in the sliding piece of the connector is also a damping the attachment to the vehicle body achieved without a separate At the damping element to arrange this attachment point.

embodiments The invention are described below with reference to drawings. Show it

1 the perspective top view of a side connector 1 the windscreen wiper system;

2 a section through the connector 1 ;

3 a front perspective view of the connector 1 ;

4 the plug connection 1 with removed sliding piece in perspective view;

5 the cut connector 1 with removed sliding piece 3 ,

In 1 is fragmentary illustrated the lateral end of a windshield wiper system according to the invention. On a mounting pipe 12 is a wiper bearing 11 stored. The attachment of the windshield wiper system takes place here in this area by a screw connection 10 and by the connector according to the invention 1 , Both the screw connection 10 as well as the plug connection 1 be with a bracket 5 connected, which in turn is fastened to the front wall of the vehicle body.

The attachment of the windshield wiper system on the motor vehicle is now according to the invention in that the windshield wiper system in a first step by arranged at both ends of the windshield wiper system connectors 1 is prefixed. Then in a second step, the screw connection of the windshield wiper system, where at the side connectors 1 Replace in the art arranged in this area arranged screw. By prefixing with the help of the connectors 1 the assembly work of the later fitting is facilitated insofar as the windshield wiper system through the connector 1 already brought into the position in which it is to be bolted to the vehicle body.

The plug connection 1 is for this purpose as in 2 shown constructed. On a guide pin 2 , which is approximately right-angled to the mounting tube 12 for mounting 5 is aligned, is an investment plate 13 arranged. On the investment plate 13 is a sliding piece 3 with a rubber cone attached 4 slidably mounted.

The guide pin 2 penetrates this one in the sliding piece 3 arranged slot 14 , as in 3 shown. The slot 14 allows a shift of the sliding piece 3 in the transverse direction of the motor vehicle and parallel to the mounting tube 12 , It is in this way a tolerance compensation with respect to the holder 5 and the receptacle arranged therein 8th possible. In 3 is the arrangement of the sliding piece 3 on the guide pin 2 shown. It can be seen that a displacement of the sliding piece on the guide pin due to the slot 14 is possible.

In order to ensure the tolerance compensation in the transverse direction of the vehicle is the sliding piece 3 against twisting to ensure the alignment of the oblong hole in the transverse direction. For this is, as in 4 shown in the investment plate 13 a sliding groove 15 arranged, which is aligned in the transverse direction of the vehicle. In this sliding groove 15 grab a rail 16 one at the to the investment plate 13 pointing bottom of the sliding piece 3 is arranged. The rail 16 runs parallel to the tolerance widening of the oblong hole 14 so that upon intervention of the rail 16 in the sliding door 15 the orientation of the slot 14 in the transverse direction of the vehicle and thus parallel to the mounting tube 12 is fixed.

Will now, as in 1 shown, the connector 1 in the recording 8th the holder 5 introduced, so first engages the guide pin in the recording 8th one. The guide pin is in this case conically formed in its front region to the introduction of the connector 1 in the recording 8th to facilitate.

The one in the recording 8th engaging rubber cone 4 is frusto-conical, whereby a guide and a sliding in of the connector in the recording 8th is guaranteed.

In 2 is the installation situation of the plug connection 1 in the holder 5 shown. The recording 8th the holder 5 hereby adapted to the course of the rubber cone 4 also conically inward, creating a form-liquid concern of the rubber cone 4 at the reception 8th the holder 5 is reached. It is thus due to the shape of the rubber cone 4 as well as the recording 8th achieved a damping elastic attachment.

The screw connection 10 at the same time in a connection position with respect to the threaded hole 9 brought. By the subsequent screwing at this attachment point is the plug connection 1 firmly in the recording 8th the holder 5 pressed.

Because the sliding piece 3 slidable on the plant plate 13 by means of the sliding groove 15 and the rail 16 is stored, it must be against sliding off the guide pin 2 be secured in the longitudinal direction. This is in the slot 14 a groove 7 as well as on the guide pin 2 one with this groove 7 corresponding circumferential collar 6 arranged.

Now the sliding piece on the guide pin 2 attached, the sliding groove 15 must be in the contact plate 13 in accordance with the rail 16 at the bottom of the sliding piece 3 is brought. Grasping sliding door 15 and rail 16 into each other, so the covenant glides 6 in the designated groove 7 in the slot 14 , The sliding piece 3 is positively on the guide pin 2 held, with a longitudinal displacement in the direction of the sliding groove 15 is still possible.

Conveniently, the rubber cone 4 firmly with the sliding piece 3 connected. The windscreen wiper system preassembled as a module is supplied with preassembled connectors. Again, it is relevant that the sliding piece 3 on the guide pin 2 secured by the means previously described.

The for the connectors 1 required brackets 5 are suitably made of sheet metal and welded to the front wall of the vehicle body.

As in 1 recognizable, it is expedient the screw connection 10 , the plug connection 1 as well as the wiper bearing 11 in one with the mounting pipe 12 to arrange connected component. This has the advantage that the attachment points and the wiper bearing 11 as compact as possible can be arranged to each other.
