Description

The The invention relates to an arrangement for fixing a cable deflection roller according to the preamble of claim 1. Furthermore, the invention relates a provided with the arrangement carrier plate for a vehicle door (also called door module or subframe) and a rope window regulator for a vehicle according to the preamble one of the independent claims.

For rope windows in vehicles two basic constructions of cable window mechanisms are known, which are preferably realized on a support plate and mounted in a vehicle door. On the one hand, there are single-stranded cable window lifter, in which only one guide rail is mounted on the carrier plate. On the other hand, there are double-stranded cable windows, in which two guide rails are mounted on the carrier plate. The guide rails are used to guide drivers, which are coupled to the window pane to be raised or lowered. At the ends of the guide rails are usually Seilumlenkrollen for the guided in the cable window mechanism ropes. Such constructions are approximately from the DE 203 13 274 U1 and are described there in detail. It also describes that the respective cable deflection roller is supported by means of a bolt which is located at the lower or upper end of the corresponding guide rail. The respective cable deflection roller is preferably fixed together with the end of the guide rail on a support and / or body part. It must be ensured that the fixation of Seilumlenkrollen and the guide rails is very safe and yet easy and fast to install.

Proposals that relate in particular to a fixation of guide rails in a cable window mechanism, are, for. B. from the DE 20 2006 011 177 U1 known.

Arrangements for fixing Seilumlenkrollen are also known. A conventional arrangement for fixing a Seilumlenkrolle at the end of a guide rail is in the accompanying 1 to which reference is made below:
Like there in 1 can be seen, includes the arrangement 10 a rope pulley 110 which by means of a bolt 100 is stored, the bolt 100 a recess 131 in a guide rail 130 penetrates to both elements, ie the bolt 100 and the guide rail 130 , on a body part 140 of the vehicle, namely on a support plate 140 of the rope window regulator, to fix. The bolt 100 itself is essentially designed as a bearing axis on which a round guide part 101 is arranged in the form of a sleeve or socket. The guide part 101 is stuck with the bolt 100 , z. B. via a shaft or a thread with bonding 102 by microencapsulation. The rope pulley 110 itself is on the lead part 101 stored, wherein the guide part 101 Has an edge projection which secures the cable drum in the axial direction, ie in the vehicle transverse direction or in the 1 to the left. As a result, a multi-piece or multi-part, from bolts 100 and leadership part 101 formed, storage for the Seilumlenkrolle 110 created.

On the guide part 101 is also a Seilumlenkrollen carrier 120 arranged the rope drum 110 secures in the opposite axial direction and has an outer border which the Seilumlenkrolle 110 partially encloses and protects or shields to the outside. This will u. a the on the pulley 110 In addition, guided in wells rope secured against slipping of the pulley and it is prevented that the circulating cable can come into direct contact with adjacent objects or components that are mounted in the vehicle door.

In the 1 illustrated known arrangement 10 is at one end or at both ends of a guide rail 130 on a carrier plate or on a body part 140 mounted as follows: The bolt 100 engages through the guide rail 130 provided recess, in particular a punched round opening 131 represents. Here is the diameter of the opening 131 so dimensioned that also the guide part 101 , at least with a graduated end, also the opening 131 can pass through or be passed through them. The guide part sits with it 101 in the opening 131 the rail 130 and secure the bolt 100 in the axial direction. The bolt 100 in turn, it continues to lead to a screw connection by means of a mounting nut 103 , which is fixed in the body of the door at a well-defined reference point. By screwing the bolt 100 firmly secured and secured at this point. Together with the fixation of the bolt 100 in the opening 131 the guide rail 130 become the bolt 100 and also the leadership part 101 Defined aligned to the reference point and fixed (so-called reference point system, short RPS system or RPS function). To secure it is at the edge of the opening 131 the bolt 100 and / or the guide part 101 by means of a flange with the guide rail 130 connected.

This known arrangement 10 thus has a fixed irreversible fixation of Seilumlenkrolle and guide rail. This disassembly, such as for maintenance and repair purposes, made difficult or even impossible. Although the known arrangement is already characterized by a safe storage of Seilumlenkrolle, yet it is desirable to find an improvement that manages with fewer components and also simplifies the assembly and possibly disassembly.

Therefore It is an object of the invention to continue the aforementioned arrangement in terms of number of components and mounting options to improve.

Solved The object is achieved by an arrangement having the features of the claim 1.

Therefore According to the invention, an arrangement for fixing a Seilumlenkrolle proposed in a rope-window mechanism of a Vehicle is mounted by means of a bolt, wherein the bolt a Engages recess in a guide rail of the cable window mechanism, around the bolt and the guide rail on a body part to fix the vehicle, and wherein the bolt is a circumferential, in particular circular groove having an edge of the Recess positively receives and the guide rail secures at least in the axial direction.

Furthermore become a carrier plate provided with such an arrangement for a vehicle door and a rope window regulator proposed with the features of one of the independent claims.

The Invention has u. a. the advantage that the bolt itself directly with the recess an at least positive connection enters and thus serves as a direct fixation of the guide rail, so that waives an additional part of leadership can be. The at least positive reception of the Aussparungsrandes in the bolt groove causes a secure connection or fixation, which can be separated again and preferably as a snap connection can be trained. This can in particular a removal, re-assembly or replacing the cable pulley, for example, during maintenance or repair work on the vehicle door, very fast and easily done.

Particularly advantageous embodiments of the invention will become apparent from the subclaims:
Accordingly, the Seilumlenkrolle be mounted directly on the bolt, whereby the bolt itself serves as a storage for the Seilumlenkrolle and also for this, the guide member is unnecessary. Thus, the storage can be made in one piece or one piece and very easy to install.

Farther For example, the groove of the bolt can preferably receive the edge of the recess in a form-fitting manner and also secure the guide rail in the radial direction.

The Arrangement is preferably designed so that the recess as round opening is formed, which has a smaller diameter as the bolt has at the lowest point of the groove, wherein the guide rail made of a material that is softer than the material of the bolt is. In this context, it is advantageous if the circular running Groove the edge of the opening positively and non-positively receives, wherein the edge of the opening deforms plastically and caulked in the groove.

Preferably at least one edge of the groove of the bolt has a curved, in particular, all-round running, projection on, so that the diameter of the bolt at the location of the projection larger as the diameter of the recess or the opening in the guide rail is. In this context it is advantageous if the domed projection the recess or undercuts opening in the guide rail and the recess or opening snaps into the groove.

Also it is advantageous if the groove of the bolt has a radially extending Edge has, over the recess or opening protrudes and acts as an axial stop for the guide rail.

LIST OF FIGURES

following The invention and the above as well as others will become apparent resulting advantages described in detail with reference to an embodiment, with reference to the accompanying drawings:

1 shows a conventional arrangement for fixing a Seilumlenkrolle and serves as a comparison for the representations of the 2a and 2 B ,

2a shows an inventive arrangement for fixing a Seilumlenkrolle with a new, improved construction in which a bolt penetrates the recess of a guide rail contacting and causes an at least positive connection.

2 B shows in greater detail a preferred embodiment of the connection between the bolt and guide rail.

The known arrangement according to the 1 has already been described as prior art and serves as a comparison in the following description of a preferred embodiment Example of the invention.

The 2a shows an arrangement according to the invention, which has a new construction, which is further improved in particular with respect to the number of components or number of components and the mounting capability. Based on 2 B details of this construction are further illustrated. On both 2a and 2 B is also referred to here:
As the 2a shows is in the inventive arrangement 20 also at one end or at both ends of a guide rail 230 on a carrier plate or on a body part 240 a rope pulley 210 assembled. The support plate (also referred to in the art as a door module or subframe) can serve the pre-assembly of components of the vehicle door, such as cable window, operating unit, side airbag module or the like. It passes through a bolt 200 one in the guide rail 230 provided recess, in particular a punched round opening 231 represents. The bolt 200 even now has the opening at the point where he 231 penetrates or penetrates, an all-round groove 205 that with the opening 231 cooperates and in particular enters into a positive connection. This is the diameter of the opening 231 so dimensioned that it is not larger than the diameter of the bolt 200 in the middle of the groove 205 is. In most applications, the material of the guide rail (eg sheet metal or plastic or composite material) is softer than the material of the bolt (hardened steel or screw grade 8.8 or 10.9). Preferably, now the opening 231 dimensioned slightly smaller, so when inserting the bolt 200 the edge 232 the opening 231 through the shape of the groove 205 shaped or cold deformed and thus in the groove 206 is caulked. This results in a positive and non-positive connection in the form of a spontaneously produced during assembly snap connection, the bolt 200 securely fixed. The snap connection can optionally be easily solved again.

The opening 231 directly penetrating bolts 200 is in turn carried on towards a screw connection by means of a mounting nut 203 , which is fixed in the body of the door at a well-defined reference point. Together with the direct fixation of the bolt 200 in the opening 231 the guide rail 230 becomes the bolt 200 secured immediately according to an RPS function. Similarly, the guide rail 230 directly through the positive connection with the bolt 200 secured directly and in the form of a releasable snap connection.

The rope pulley 220 is on the bolt 200 stored itself and thus experiences a direct storage, which is particularly advantageous in terms of dimensions and component tolerances than the conventional constructions.

The bolt 200 is in the direction of the fastening screw 203 graduated, so that he in particular a border or stop 207 has for the guide rail, which secures them directly in the axial direction. Thus, also proves the fixation of the guide rail 230 especially in terms of dimensions and component tolerances as advantageous over the conventional designs.

As in particular on the basis of 2 B can be seen, has the groove 205 in the insertion direction of the bolt 200 a domed ledge 206 , the z. B. as a thickened border, as a nose or multiple noses, etc., can be configured. The lead 206 acts as an undercut in the caulking of guide rail 230 and bolts 200 , Besides, the bolt secures 200 directly also the Seilumlenkrollen carrier 220 both in the radial and in the axial direction. The caulking of the components also acts as a circular fuse or against rotation. Overall, there is a multiple backup, namely a caulking against twisting or torsion and an undercut with caulking against axial load.

As based on the 2a and 2 B becomes clear, occurs during mounting the caulking of guide rail 230 and bolts 200 in a single process step or production step.

During assembly, only the bolt needs 200 with attached rope pulley 210 and rope pulley support 220 in the opening 231 the guide rail 230 to be introduced. When defined snapping or during plastic deformation for caulking the bolt groove 205 with the boundary 232 the guide rail opening 231 takes place immediately and in one step, a secure and RPS-compliant connection, which can possibly later be reversibly solved again as far as possible.

The Arrangement according to the present invention especially because of the smaller number of components and the simple Handling during assembly particularly cost-effective to realize. The invention can be used in particular for cable windows used in motor vehicles.
