Description

Vehicle blind arrangement

The present invention relates to a vehicle blind arrangement according to the preamble of claim 1, and to a method for producing a vehicle blind arrangement according to claim 3.

A generic Fahrzeugroiloanordnung is known from DE 10 2010 018 259 A1.

Known vehicle blind arrangements have a roller blind, with a guide strip which extends along a pull-out of the roller blind, and is in communication with a side edge of the blind. The guide band is provided to be slidably mounted in a fastened to a vehicle body guide rail. A textile tape is provided, which connects the blind sheet to the guide tape, wherein the textile tape is sewn to the guide tape by means of a seam. It is an object of the present invention to provide a vehicle blind assembly and a method for producing a vehicle blind assembly, which or soft a particularly simple and thus inexpensive production allows the same.

This object is achieved by a vehicle roller blind arrangement according to the characterizing part of claim 1, as well as by a method according to claim 3.

In a vehicle blind arrangement according to the invention, punched holes are provided in the guide band for connecting the guide strip to a roller blind drive or to a winding shaft. Such an opening in the guide band in the form of a punch-out can serve, for example, for connection to a coupling of a tensioning bolt, by means of which the roller blind can be moved. Punctures, which are arranged at one end of the guide band, which is associated with a winding shaft, can serve to form a frictional connection between the guide band and the winding shaft, on which the roller blind can be wound guarantee. Furthermore, it can also be provided that a corresponding recess in the guide band serves to connect a drive cable, or as a positioning aid for positioning the guide bands, for example, when installed in a vehicle. An advantage of a vehicle blind arrangement according to the invention is that comparatively easy connection points for the vehicle blind arrangement can be created on the punched in the guide band. This offers the advantage, inter alia, that in a continuous production process, a long (compared to a cut guide tape) guide tape material can be sewn with a long textile tape material, and in the continuous manufacturing process further cutting to a specified length to a Textilmo - dul (with the guide tape sewn textile tape) can be performed.

In a method for producing a vehicle roller blind assembly having a Roliobahn, and a guide strip which extends along a Auszieh- direction of the blind sheet and is in communication with a side edge of the blind sheet, wherein the guide band are slidably guided in a fastened to a vehicle body guide rail can in the course of the process, the leader tape is sewn with a textile tape and the guide band and the textile tape attached to the side edge of the Roilobahn. According to the invention, the sewing of the leader tape to the textile tape is a continuous manufacturing process in which a leader tape material having a length for a plurality of leader tapes and a textile tape material having a length for a plurality of fabric tapes are fed to a machine. By means of the machine, the leader tape material and the textile tape material are sewn together. Then, along the machine, the sewn tapes are cut to a specified length to form a textile module. The specified length preferably corresponds substantially to the length of a Roliobahn, which may be programmed in the machine, for example, together with a seam pattern. In the area in which cutting or punching is carried out for cutting to length, at least one punched out of the guide strip is punched for connecting the guiding Bands on a Rolioantrieb or on a winding shaft or as a positioning aid for positioning the guide belt. By punching out of the guide band creates an opening in the guide band. In the case of a positioning aid, this can be used for positioning the guide bands, for example, when installed in a vehicle.

Due to the fact that the punching is punched out only during the production process and is not already punched out in the guide strip material, which is supplied, for example, on rolls, different textile modules can be produced with the same guide strip material. Furthermore, eliminates a cumbersome positioning of the guide strip material in the machine with respect to existing punched, since they are punched out only in the machine.

Further preferred embodiments of the invention will become apparent from the dependent claims.

Preferably, the punching of the punching is carried out simultaneously with the cutting or punching for cutting to length. For example, a single punching tool can be used.

In a particularly preferred embodiment of the invention, the punched holes of successively manufactured textile modules are arranged mirror-symmetrically in the guide strip material such that a textile module for a right-hand side edge of a roller blind arrangement is manufactured alternately after a textile module for a left-hand side edge in the continuous production process. In a continuous production process preferably a guide belt material and a textile belt material is continuously unrolled from respective rollers and sewn together. As soon as a programmed length of a textile module has been reached, the textile module is cut to length. It can be produced as continuous pairs of textile modules, as long as appropriate strip material for leader tape and fabric tape is fed by a respective roll. In this case, an axis of symmetry for the punching of a cutting or punching line for cutting to length of a textile module correspond. This mirror symmetry with respect to the cutting or punching line ensures that a textile module for a left or a right side edge of a roller blind arrangement is alternately produced alternately. If, for example, a punched-out for a connection of the guide belt to a winding shaft is considered, then in the continuous production process, a textile module is first manufactured for a first side edge of the roller blind arrangement, for example for the left-hand side edge. When sewing the leader tape material with the fabric tape material to this left fabric module, fabric tape material and leader tape material are sewn together starting from, for example, one end of the textile module associated with an end portion of the roof panel in a finished vehicle blind assembly (ie, facing away from the winding shaft) to the end later associated with the winding shaft. As soon as this area is reached in the sewing process, a bolt seam is executed and, together with the punching process for cutting the textile module to length, a punch-out for connecting the guide belt to the winding wire is punched out of the guide belt. In the subsequent textile module, which is accordingly provided for the right-hand side edge of a vehicle roller blind arrangement, the stamping for binding the guide strip to the winding shaft is started in the continuous production process. This punching can be punched out at the same time as the previous punching and the cutting to length of the preceding textile module (for the left side edge) or the separation of the modules. The continuous and alternate production of left and right textile modules is therefore possible because the cutting or punching line for cutting to length of a textile module at the same time the axis of symmetry for the mirror-symmetrical punch-outs. During production, you can start with a left or right textile module. The sewing of a first textile module of a first side of the roller blind is started at a first end of the textile module. The subsequent manufactured textile module is then provided for the opposite side, and the sewing is started here at the opposite end, so that in continuous manufacturing successively left and right Textiimodule are always made rotated by 180 ° to each other. The punched out, which are punched out of the guide band, can simultaneously open the stitched with the guide band or this surrounding textitband. In a further preferred embodiment of the invention, however, the textile tape is removed in a region of the guide tape in which the punched out punched out prior to punching by means of a hot stamp or by laser cutting or by hot trimming. This simplifies the punching process, since only the guide band has to be punched, but not the tex- tile cover in the form of the textile band. A hot trimming can be carried out, for example, by means of a hot metal wire or a hot knife. In these methods, the textile tape is thus locally removed by a melting or combustion process.

Preferably, holes are provided in the guide band material, and when suturing the leader band to the textile band, a suture stitching thread is passed through the holes of the leader band. For example, a needle for stitching the textile tape material with the guide tape material does not need to pierce the guide tape, but the needle is passed through the corresponding holes of the guide tape. This is particularly advantageous because it reduces the stress on the sewing needle when using a metal strip as a guide tape. The corresponding holes in the guide band can already be pre-punched in the guide band material.

The textile band preferably has three legs in cross-section, with two legs being guided at least partially and in opposite directions around the guide band and sewn thereto, and the further Schenket is sewn to the Roliobahn. The fact that two legs of the three-dimensional textile tape wrap around the guide band, this can be performed on the one hand friction in a guide channel of a guide rail, and on the other hand, a stable mechanical connection between the textile band and guide band can be ensured.

In a further preferred embodiment of the invention is carried out before cutting to a range in which the cutting or punching to cut to length is performed, a bolt seam through guide tape and textile tape. This prevents a dissolution of the seam between the guide belt and the textile belt, wherein such a bolt seam can be produced, for example, by repeated stitching along a defined length transversely or longitudinally to the guide belt.

In the following the invention will be described by way of example with reference to the accompanying drawings. Showing:

Figure 1 shows a cross section through a guide strip which is guided in a guide rail; and FIG. 2 is a plan view of a guide tape according to the invention.

FIG. 1 shows a cross section through a Roliobahn 10, which is connected via a textile belt 18 with a guide band 12. The guide band 12 is displaceably mounted in a guide channel 14 of a guide rail 16. The guide rail 16 extends in a vehicle longitudinal direction, so that the roller blind 10 can also be moved in the vehicle longitudinal direction, and they can shade a glazed roof opening in a vehicle roof area. The illustrated region of the roller blind 10 is a section of the roller blind 10, which represents a lateral edge region of the vehicle blind assembly.

The guide tape 12 is sewn by means of a seam 20 with the textile tape 18, which in turn is sewn by means of another seam 38 with the Roliobahn 10. For this purpose, the Y-shaped textile tape 18 has a first leg 22 which is sewn to the roller blind 10. Two further legs 24 and 26 of the textile band 18 are sewn to the guide band 12. For this purpose, the two werteren legs 24 and 26 are guided in opposite directions at least partially around the guide belt 12 or looped, so in the region of holes 28 of the guide belt 12th the leg 24 of the textile band 18 rests against the guide band 12 from below, and the leg 26 lies on the guide band 12. The leg 24 of the textile band 18 is made long enough to completely surround the guide band 12 and on the leg 26, which is on top the guide tape 12 is, comes to rest. In the area of the holes 28 of the guide strip 12, this results in a "layer sequence" from top to bottom starting with the end of the leg 24, the leg 26, the hole 28 and a central region of the leg 24. By this layer sequence, the seam 20 is guided The guide band 12 is configured T-shaped together with the textile band 18 (and the associated legs 22, 24 and 26) and the roller blind 10, whereby the guide band 12 is deflected by approximately 90 ° for mounting the roller blind 10 on the guide rail 16 is that the guide belt 12 as well as the blind sheet 10 is guided horizontally aligned.

2, the continuous production of textiimodulen, so combinations of textile bands 18 and guide strips 12 for each of a left and a right edge of a vehicle blind assembly will be explained. For this purpose, in a machine, which is a combination of a sewing machine and a punching machine, a strip material is introduced, which has the multiple length of a laterally cut to length guide strip 12. Holes 28 are already punched into this strip material, through which connection in the manufacturing process by means of the seam 20 with the textile strip 18 of FIG. 1, not shown here, is carried out. As soon as a predetermined length for a textile module is achieved in this continuous sewing of the guide strip material and the textile strip material, an automatic lengthening takes place along the punching line 32 by a stamping process. In the area in which cutting or punching is carried out for cutting to length, a bar seam (30) is formed by guide strip (12) and textile strip (18). Together with the punching or punching of the textile module along the punching line 32 punched out 34 and 36 are punched out, which serve to tie the guide belt 12 to a roller blind or to a Wickelweile. It is important that all cutouts 34 and 36 are designed and arranged mirror-symmetrically to the punching line 32. The punched-out section 36 is oval in this case with a larger cross-section in the longitudinal direction of the guide strip 12, which serves to compensate for production surprises Alternatively, a punched out can also be rectangular. The holes 28 may also, but need not be designed or arranged mirror-symmetrically to the punching line 32. The subsequent arrangement of the punched out 34 and 36 offers the great advantage that at any point of the guide strip material with the production of a textile module 40 or 42 can be started.

With the execution of the punching line 32 for cutting the left in the image direction textile module 40 not only the punch 34 and 36 punched this left textile module, but also the corresponding punched 34 and 36 of the subsequently manufactured right textile module 42. The left in the image direction of Figure 2 Textilmodui 40 may be a left textile module 40 for a left edge region of a vehicle rolling system according to the invention. Accordingly, the textile module 42 shown on the right is then a right textile module 42 for a right edge region of a Fahrzeugrolioanordnung. Thus, after the left-hand textile module 40 has been brought to the desired length by cutting along the punching line 32, the right-hand textile module 42 can be sewn. As can be seen from FIG. 2, the right-hand textile module 42 can be folded downwards (in the image direction) such that it comes to rest parallel to the left textile module 40 and the punching line 32 of the two textile modules 40 and 42 lies to the right in the image direction. By cutting along the punching line 32 and by the fact that, in particular, all the punched-out sections 34 and 36 are arranged mirror-symmetrically to the punching line 32, two textile modules 40 and 42 have therefore been produced, which in turn are mirror-symmetrical with respect to a central longitudinal axis of the roller blind 10. if they are sewn on the left and right to the shade 10. These symmetry conditions ensure that as long as a leader roll material is fed continuously from one roll and textile ribbon material is fed continuously from another roll, a left textile module 40 alternately followed by a right (twisted) textile module 40 followed by a left textile module 40 etc. can be made continuously.
