Description

object The present invention is an interior trim part with a Carrier, a visual decor surface and one between the carrier and the decorative surface arranged intermediate layer. The carrier also has a in the intermediate layer protruding groove for receiving a positioning on, and the decor surface consists of a first and one with the first connected by a seam second partial surface. In addition, one is on one of the visible side of the decorative surface opposite bottom fastened in the area of the seam, into the groove protruding positioning available.

Such an interior trim part is for example from the document DE 10 2004 053 133 A1 known. With this invention, the object has been achieved to provide a coating with at least one seam for the lining of motor vehicle interiors, with which it is possible to easily position the seam with respect to a carrier material in the lamination and / or foam back, at the same time a seal against the intermediate layer, which is often a foam layer, should be given.

That in the DE 10 2004 053 133 A1 listed positioning element is made of a plastic or a metal and is connected directly to the decorative surface. The connection is made by means of a functional seam. The seam must penetrate the relatively hard positioning element, which can lead to damage to the decorative surface, whereby a lot of waste is produced. However, in the DE 10 2004 053 133 A1 also mentioned that the fixation between the positioning and the decorative surface can be made by gluing.

The Object of the present invention is an interior trim part to create, during which less during production Committee arises and the connection between the positioning element and the decor surface easier and possible thus cheaper.

These The object is achieved by an interior trim part according to claim 1.

in this connection is an interior trim part with a carrier, a visible decorative layer and one between the carrier and the decorative layer disposed intermediate layer, wherein the carrier has a groove for receiving a positioning and the Decor layer of a first and one with the first along one Seam connected second sub-surface consists and a on one of the visible side of the decorative layer facing away from the bottom in the area the seam has fixed positioning element projecting into the groove, wherein the positioning element is sewn to the decorative layer Seam banner, one with the seam flag firmly connected plastic profile and has at least one clip held in the plastic profile, wherein the plastic profile is disposed in the groove and the clip an opening of the carrier disposed at a bottom of the groove engages behind. Instead of the clip can also be a rivet, a pin, a screw or the like may be provided. In the context of the present description is usually referred exclusively to the clip, the However, there are also rivets, Pins, fittings, etc., unless otherwise stated is.

This Interior trim part has the particular advantage that the wearer must have no undercut and therefore inexpensive to manufacture is, just pass through openings of clips, rivets, pins, screws etc. The undercut will then through the clip or Never etc., the opening in the carrier engages, guarantees.

Especially It is also advantageous to correct the seam position by a displacement of the clip within the plastic profile becomes possible.

The Invention thus enables the cost-effective Production of a positioning element or inner lining part, in the particular multi-part decorative layers (for example Leather) on the one hand have an exact positioning of the seam, the ornamental or functional seams between individual parts of Decorative layer additionally the attachment of the seam flag serve and the positioning on top of that still the foam or liquid-tight seal in the seam area is used. hereby The production is significantly simplified, making a cost-effective Manufacture with less waste and lower costs possible becomes.

advantageous Further developments of the present invention are described in the dependent Claims shown.

A advantageous development provides that the decorative layer of textile material, Plastic film, synthetic leather or leather is. Especially with leather It is advantageous that this material often only in limited area sizes provided (this can be done on instrument panels important) and that there are also tightness problems between the individual parts can come, which excluded by the invention can be.

An advantageous development provides that the seam flag of a nonwoven material, preferably a needle felt, in particular of poly propylene, is. This material is easily pierced by a sewing needle, it does not lead to the destruction of a plastic profile or the like, also adapts the seam flag the course of the decorative layer particularly well, is therefore invisible and also offers good sealing properties. Of course, come for the seam flag other materials, especially textile materials in question.

A advantageous development provides that the plastic profile made of polypropylene. This material is particularly inexpensive and easy to process industrially. The plastic profile can, for example even be connected to the seam banner directly after extrusion, in this way the seam lug cohesively with the Plastic profile to connect. This can be an integration of the seam flag be in the slot of the plastic profile, it is also possible the seam flag on the surface of the plastic profile to install. However, it is also possible that the seam flag is clamped with the plastic profile and / or material fit, in particular by gluing or encapsulation, is connected.

A advantageous variant provides that the plastic profile and the Clip (rivet, pin, screw, etc.) not cohesively with each other are connected. For example, it is possible that the Clip (rivet, pin, screw) only form-fitting from Plastic profile is held so that it is perpendicular to the carrier or can not be removed to the decorative layer. Along the course of the Plastic profiles can be the clip, rivet, pin screw etc. however be displaceable, this may be one Adjustment of the seam also in a late stage production still possible.

A advantageous development provides that the clip in a plastic profile Anordendable base and has a substantially peg-shaped Continued to engage behind the opening of the carrier followed. The clip can thus be manufactured as a single part be, with a break of the clip is not complete Replacing plastic profile but a lighter replacement of this Item is possible. The clip can be made in particular Plastic or metal can be produced inexpensively.

A advantageous development provides that at least one opening the carrier for receiving a clip, rivet, pins screw provided as a longitudinal slot along the groove of the carrier is. This is the clip not only in the plastic profile but even in the carrier from the longitudinal position ago variable. Preferably, the provision of a single hole for every clip, this hole can run round or square be possible, this is an exact positioning of the clip along the longitudinal course of the plastic profile possible.

A further advantageous embodiment provides that the clip, rivet, Pin, screw etc. is designed so that it is from the decor layer repellent side of the carrier in the plastic profile form-fitting is insertable. This results in a very light Mountability and high variability in the sequence the manufacturing steps. So it is even possible in hindsight with a not quite optimal seam correction make.

A Another advantageous embodiment provides that the positioning element is designed so that a first and second partial surface connecting seam foam-tight is completed by the positioning. For this purpose, preferably the seam lug itself foam-tight, elastic properties of the seam flag are beneficial to it too To seal a thread even better, because this even closer can be enclosed.

The Intermediate layer between the support and decorative layer may preferably as a foam layer (foamed in the tool or shoring a previously finished foam layer), but there are other possibilities ge, for example, for purposes of a desired special Haptik a spacer knit, etc. are used.

A advantageous development provides that the groove undercut is executed, these preferably as two at the Carrier integrally arranged webs is executed. This undercut-free arrangement is particularly cost-effective in the production, as for example on slide in the injection mold The carrier can be dispensed with.

A Another embodiment provides that the groove designed in this way is that the decorative layer and / or the seam flag on webs of the groove is supported. This will give a defined distance achieved in the seam region of the decorative layer to the wearer, this gives a visually very high quality impression of the interior trim part.

It is also advantageous that the seam with which the seam flag sewn to the decorative layer, one on the visible side the decorative layer is visible functional or decorative stitching. hereby will ensure that both tightness and positioning and production of functional and decorative stitching in a single step and thus labor costs remain low.

Further advantageous developments are dependent on the others Claims explained.

The Invention will now be explained with reference to several figures. It demonstrate:

1a to 1c a first embodiment of an interior trim part or positioning element according to the invention,

2a to 2c a second embodiment of an interior trim part or positioning element according to the invention,

3 a side view of a mounted on a decorative layer positioning with four clips, and

4 a carrier for connection with the device according to 3 ,

1a to 1c show details of an interior trim part according to the invention 1 , This shows a decorative layer 3 made of leather, which is composed of two sub-surfaces. These are the first part surface 3a as well as the second part surface 3b , The sub-surfaces are by means of a seam 7 sewn together. The direction of the seam is perpendicular to the plane of the page. Parallel to this connecting seam two seams are arranged, which are visible from the visible side S of the decorative layer ago. These seams connect each for the first part surface 3a or the second sub-surface 3b the ends are "U" -shaped, with the legs of the U connecting each individual sub-surface, respectively. With sewn in here is a seam flag 6a which has two legs in the present example. Each of these legs is connected to each part of a surface, the left leg of the seam flag 6a is with the lower leg of the "U" of the first face 3a connected, the right leg of the seam banner 6a is with the lower leg of the second sub-surface 3b also connected by sewing.

The seam banner 6a is in a plastic profile 6b firmly attached. The plastic profile is made of polypropylene and was connected after its extrusion with the plastic profile.

The Suture flag is in this case of a needle felt, this is light pierce with a needle. This textile material is also sufficiently stable in temperature when combined with polypropylene, so that here no warping or damaging the plastic flag is to be feared.

The two legs of the seam flag 6a resting on webs, the two sides of a groove 5 (please refer 4 ) are mounted. This groove has openings (see, for example, openings 5a in 4 ). These openings are engaged behind by at least one clip 6c , This clip has a base in an undercut groove of the plastic profile 6b is held. At this base of the clip is followed by a pin-shaped portion, which is the carrier 5 engages behind and thus for the maintenance of the plastic profile 6b in the groove 5 provides. This is also about the associated with the plastic profile seam flag 6a and the first and second sub-surfaces sewn in turn 3a and 3b the positioning of the decorative layer 3 specified.

This in 1c once again shown alone positioning 6 consists of the seam flag 6a , the plastic profile connected materially 6b and at least one clip 6c which is inserted in an undercut groove of the plastic profile. Both the seam flag and the plastic profile are executed in a constant cross-section perpendicular to the paper plane, the clip 6c is essentially rotationally symmetrical with respect to the connection between base and pin (see also 3 ). The clip are made of plastic, a replacement of a clip that has broken out of the groove, for example, is readily possible because there is no permanent connection to the plastic profile.

This in 1a to 1c shown interior trim part 1 or positioning element 6 is designed so that the first 3a and second sub-surface 3b connecting seam 7 foam-tight is completed by the positioning 6 , This is especially important in the case where the interlayer 4 from a foaming in the carrier material (for example isocyanate and polyol) is formed. However, the foam layer can also be designed as a finished foam layer or spacer fabric. In the 1a respectively. 1b To be seen supporting the decorative layer on the groove adjacent webs ensures that here is given a defined distance to the carrier base and thus a uniform thickness (adapted to the thickness of the intermediate layer 4 ) is possible. The fact that the seam lug or the ornamental or functional seam connected to this seam lug, which in this case is visible on the visible side, is supported on the groove, also has further advantages in terms of tightness.

1a shows in summary so the interior trim part 1 . 1b shows the same arrangement, but without a clip inserted 6c or rivet, pin, screw, etc.). 1c shows a complete positioning element 6 that made of seam banner 6a , Plastic profile 6b and at least one clip 6c consists.

The arrangement according to 2a to 2c is according to the first embodiment according to 1a to 1c built up. It is different, however, that (see 2a . 2 B respectively. 2c ) the seam banner 6a has a greater distance between the left and the right leg, each of the two legs is here in another area of the plastic profile 6b arranged. Except that's the seam 7 the one seam, in addition to the connection of the decorative layers 3a and 3b also the seam flag with fixed. 2a to 2c show a decorative layer, the only decorative seams left and right parallel to the seam 7 has (both the seam 7 as well as the decorative seams 8th have a course perpendicular to the leaf level) In addition, the first sub-surface 3a or the second sub-surface 3b not in the contact area in each case again umugt, so that a lower height of the decorative layer in the seam 7 results.

The remaining aspects or features of the embodiment according to 2a to 2c are appropriate 1a to 1c , so that reference is made to avoid repetition thereof only.

1a - 2c each show embodiments of positioning elements, in which the seam flags within the plastic profile 6b are attached. But it is also possible to attach the seam tab only on the outer surface of the plastic profile.

3 shows a side view of a decor 3 that already by means of a seam 7 with a seam banner 6a is sewn and in which the seam flag 6a with the plastic profile 6b is connected cohesively. The undercut groove in which the clips 6c are good to see (at 3 it is a lateral view of the decorative layer 2a respectively. 2 B , here the decorative stitching 8th not shown).

Along the undercut groove within the plastic profile 6b are the clips 6c as indicated by the arrows, slidable to the left and right of the page. As a result, a slight adjustment of the seam during the production of the interior trim part is still possible.

4 shows a plan view of a carrier 2 , where here the groove 5 with the two adjacent webs, which include the groove is shown. Along the Nutverlaufs are openings 5a given, in each case a clip 6c can be clipped to thereby the positioning element 6 to fix. There are also alternative hole shapes possible, for example, square hole shapes or hole shapes in the form of longitudinal slots.

It is also possible for a clip 6c from the decor layer 3 repellent side of the wearer 2 out in a plastic profile 6b (or in the undercut groove of this plastic profile 6b ) can be introduced. This makes it possible, for the first time "from outside" the fixation of the positioning or the determination of the course of the seam 7 to influence.
