Description

The invention relates to a method for producing an interior trim part Vehicle, in particular a motor vehicle, according to the preamble of claim 1 Device for performing the method according to the preamble of claim 8, and an interior trim part for a vehicle, in particular for a motor vehicle, according to the Preamble of claim 15.

In vehicles such as B. motor vehicles, interior trim parts are z. B. in the form of a Dashboard or in the form of a steering wheel hub cover, behind which Airbag modules are arranged as part of an occupant protection device. To a The airbag exits through the interior trim part in front of the vehicle occupant To enable an airbag outlet opening is integrated in the interior trim part, which in the not activated state of the occupant protection device and thus of the airbag module by means of a covering device, such as. B. one or more flaps covered and is closed. In the event of activation of the occupant protection device and thus the Airbag module, the cover is moved away from the airbag outlet opening to release them for an unhindered deployment of the airbag.

Such a structure is known for example from EP 0 867 346 A1. The Cover device of the airbag outlet opening is formed here by two cover flaps adjoin each other with border areas in a border area and so via traction means are connected to a rearward displaceable component of the occupant protection device, that in the activated state of the occupant protection device by the Airbag outlet opening directed backward displacement of this component over the Traction means a tractive force can be applied to the cover flaps. So that can Cover flaps opening the airbag outlet opening in the direction of Vehicle interior are pulled away inward behind the interior trim part. Specifically here are the border areas adjacent to the opening edge area Cover flaps Pins are provided that protrude from both sides of the cover flaps and in grooves correspondingly formed at the opening edge region of the airbag outlet opening are led. In a first embodiment, a rod connection is used as the traction means  provided, each of the tie rods on the one hand on the housing of the gas generator and on the other hand is articulated on the edge area of the cover flaps on the opening edge. in the If the occupant protection device is activated, the gas generator is activated moved back so that a pulling force on the cover flaps via the two tie rods is exercised so that it starts from the airbag outlet opening edge area inwards and pulled back. The cover flaps move on the through the pins and grooves predetermined curve profiles. In an alternative embodiment this is done the tensile force is applied to the tie rods by means of a rotary piston. Another alternative the tie rods are shifted using a linear piston-cylinder arrangement. In In another alternative embodiment, the gas generator blows into another component one, which is coupled to the traction means, so that when moving the Component a tensile force is applied to the cover flaps.

The airbag outlet opening is here in a carrier layer of the interior trim part trained, which together with the cover flaps towards the vehicle interior has a common surface layer as the outer skin. The backing layer is made from a relatively stable inner skin and a foam material. When activated the occupant protection device and a related withdrawal of the Cover flaps, however, there is a risk that the outer skin is formed Slush skin detaches from the backing layer, especially from the foam material, causing this can lead to individual parts of this slush skin and / or from the airbag being deployed If necessary, also of the foam material towards the outside towards the vehicle occupant be taken away, so that the danger of flying around loose loose particles is given, which can pose a potential hazard to the vehicle occupants.

In order to avoid this, a method is already known from WO 99/61288 is known with which an interior trim part for a motor vehicle is produced, the one Has carrier layer in which at least one airbag outlet opening is formed, which in the Basic state installed in the motor vehicle with the occupant protection device not activated and thus not activated airbag module by means of a likewise in the carrier layer trained cover device is covered and closed. The carrier layer and the at least one covering device has a common one that forms the outer skin Surface layer as a slush skin, the slush skin in the area of at least one Cover device connected to a reinforcing layer, preferably a fabric layer is. The first step in the process is to produce the slush skin Slush material in a shape that determines the shape of the slush skin Mold temperature heated mold introduced in which the introduced slush material  at least partially sintered and gelled. Then in a second Process step before cooling the slush skin the reinforcement layer in one of the at least one slush skin area assigned to the covering device of the gelled slush skin attached and by means of a pressing device in a defined pressing area in the gelled slush skin pressed in so that the reinforcement layer bakes with the slush skin.

Specifically, the pressing device is here by a not defined and explained dimensionally stable stamp. The reinforcement layer designed as a fabric layer can then according to a first embodiment during the foaming between the Outer skin and the inner skin on one from the inner skin towards the outer skin protruding catch hook can be hooked in, so that a better connection between the Outer skin and the stable inner skin is given, which is to avoid that the The outer skin peels off when the cover device is opened. Alternative to this relative elaborate and with certain uncertainties determining the fabric layer One or more hooks is the definition of the free tissue end at the Inner skin over conventional fasteners such. B. gluing, riveting or Screwing provided.

However, it is problematic when the tissue is pressed into the gelled slush skin that in particular due to tolerance-related inaccuracies in the manufacture of the Slush shape to form a slush skin with a different area Thickness of material can come, which can also be caused by additional areas that may occur or less slight temperature fluctuations in the slush form can be favored. A position-defined application of Fabric layers on the slush skins are difficult, so there is a risk that the The fabric layer is anchored in different areas or firmly in the slush skin, z. B. in areas with a relatively thin material thickness may or may not be indented and hardly is anchored to it. As a result, there is a risk that the slush skins in a Tensile stress as part of an activation of the occupant protection device in unwanted detachment from the fabric layer, which can lead to the Airbag when it is deployed individual parts of the slush skin and possibly the foam material be taken out towards the vehicle occupant, so that furthermore there is the danger of flying around of individual loose particles, the one can pose a potential hazard to vehicle occupants.

It is therefore an object of the invention to provide a method for producing a Interior trim part of a vehicle, in particular a motor vehicle, and a  To create a device for performing the method with which a position-defined Applying reinforcement layers, in particular fabric layers, to slush skins Interior trim part is possible. Another object of the invention is to provide a To create an interior trim part with the risk of a slush skin peeling off a reinforcing layer, in particular a fabric layer and thus a carrier layer can be significantly reduced.

This object is achieved with respect to the method with the features of claim 1.

According to claim 1, the at least one reinforcement layer by means of a contour of the pressing surface of the pressing device which adjusts the slush skin to the gelled slush skin pressed and pressed.

With such a contact surface of the slush skin which adapts to the contour Pressing device is advantageously a position-defined application of the reinforcement layer, preferably a fabric layer on the slush skin possible because of such a structure the pressing surface of the pressing device can be adapted to the contour of the slush skin, that an even contact pressure of the fabric layer on the slush skin even with large manufacturing-related tolerances and dimensional deviations in the slush form and thus the Slush skin is possible, d. H. that the fabric layer especially in slush skin areas pressed into the slush skin with a relatively thin material thickness for good anchoring becomes. The adaptation to the specific pressing conditions is carried out automatically by adapting the contour of the aripress surface to the slush skin, so that a such a method, in particular also diverse in connection with the most varied Forming interior trim parts can be used. This is how this procedure is in particular also suitable for interior trim parts where z. B. the airbag outlet opening in an angled arcuate transition area is arranged, as z. B. in Passenger area of an instrument panel as an interior trim part can be the case without that this requires a special stamping tool. It is preferably the Reinforcement layer around a fabric layer, but basically also other materials can be used as fabric materials. The following, however, is with regard to the preferred use of a fabric layer mostly also uses this term.

Overall, there is therefore a simple and advantageous pressure and position-defined application possible from fabric layers to slush skins, so that the process as a whole is also relative is easy and inexpensive to carry out.  

Depending on the geometry and specific design of the covering device, e.g. B. the Cover flaps can be one or more fabric layers on the invention Way are pressed into the slush skin, possibly also several separate Contact surfaces with contour adjustment can be available. Basically there is different possibilities of the pressing device with the contour of the Form slush skin-matching contact surface, z. B. by the contact surface of a Form stamp is designed accordingly compliant. The is particularly advantageous Pressing device, however, formed by an airbag-like pressure pad, which for Volume increase preferably hydraulic and / or pneumatic with pressure is applied. Such a pressure pad is particularly simple and inexpensive producible and enables a particularly simple and good way according to the invention Contour adjustment.

According to a preferred embodiment of the method, the contact pressure of the Pressing device during a predetermined holding time depending on at least the slush skin material thickness and / or the degree of gelling and / or the fabric layer structure and / or the pressure value of the pressurization and / or the geometry of the Pressure area applied. The contact pressure is optimally set so that a very good connection between the tissue material and the slush skin is achieved contributes to the risk of the slush skin becoming detached from the tissue layer in the activated state of an occupant protection device is significantly reduced.

After the second method step, the pressing device is preferably of the form moved away and the carrier layer applied to the slush skin, preferably after the Cool down the slush skin. This ensures that the fabric layer is securely attached to the Slush skin is connected.

In a preferred specific embodiment, the carrier layer is formed First a stable inner skin as part of the carrier layer spaced from the slush skin arranged, this spacing preferably via attached to the inner skin and / or molded webs and / or ribs is reached. Then the Area between the slush skin and the stable inner skin with a foam material foamed, creating a connection between the stable support layer and the Slush skin is made. The free ends of the at least one can be advantageous fabric layer connected to the slush skin before foaming through the stable Inner skin to be threaded around this when installing the interior trim part with a when the airbag is activated, preferably movable away from the airbag outlet opening  to connect relocatable, stable component, via the direct or indirect one Tractive force can be applied to the covering device. This can result in a Moving the at least one covering device away from the airbag outlet opening Slush skin as outer skin not from the backing layer, especially from the foam material, detach and can thus separate parts of the slush skin and / or the foam material from inflated airbag not taken towards the vehicle occupant become.

In a particularly preferred embodiment, it is also provided that the An additional side of the tissue layer facing away from the slush skin Material layer, preferably a dimensionally adapted to the pressing area Foil is applied, which is preferably together with the at least partially Pore structure showing tissue layer on the gelled and thus an increased Temperature-bearing slush skin is put on. This ensures that the additional layer of material warmed by the heat given off by the slush skin and is melted so that it is at least partially embedded in the fabric layer merges with the slush skin in the contact area. This makes it a particularly safe one The tissue layer is anchored in the slush skin. A particularly good connection is achieved when the slush skin and the additional material layer from the same Are material to achieve a good fusion with each other. So that becomes a particularly firm anchoring of the tissue layer in the slush skin is achieved, so the danger the detachment of the slush skin from the fabric layer in the event of a tensile load is significantly reduced again. For example, such a film with a Material thickness of approximately 0.2 mm. Such a thin film can be easily Way to be melted. In addition, there is no second with such a method Slushing necessary because the heat of the mold, preferably one Electroplating tool, is still sufficient for a fusion.

The object is achieved with respect to the device with the features of claim 8.

According to claim 8, the pressing device is part of a carrier device for the Reinforcement layer, preferably a fabric layer and has a contour of the Slush skin adapting contact surface, which in a preferred embodiment a pressure pad is formed, preferably for increasing the volume with pressure pneumatically and / or hydraulically, can be acted upon.  

With such a device, as has already been explained in detail above, an interior trim part are advantageously produced, in which the risk that the slush skin in the event of activation of an occupant protection device with a Can detach airbag module from the reinforcement layer, preferably a fabric layer, be significantly reduced, so that overall functional reliability is significantly increased becomes. In particular, such a device is universal in the production of a large number of different interior trim parts can be used, so that not for each special Inner trim part uses a separate stamp and possibly a separate device must be, so that the cost of components and thus the use of materials and the Manufacturing costs can be significantly reduced overall.

According to a further preferred embodiment, the carrier device comprises a cavity open on one side as a receiving space for the pressure pad, in which the Pressure pad is added. The cavity has one at least in the opening area Contour according to the specified pressure range, so that with pressure pressurized and inflated pressure pads a good pressing of the fabric layer in the predetermined pressure range enables. Is the contact area of the fabric layer for example, rectangular, the cavity can at least in Opening area can be formed with a corresponding rectangular contour, so that the pressurized pressure pad at least in the opening area a has a corresponding pressure pad contour. Advantageous can thus in a simple manner, for. B. by appropriate inserts in the cavity Opening area a quick and easy adjustment to the geometry of the specified pressure range can be achieved.

The pressure pad fills the cavity preferably in the inflated state essential, whereby a particularly even pressure of the fabric layer on the Slush skin is possible.

A particularly simple way of applying pressure results when in the Cavity in which the pressure pad is received, a pressure supply line is guided, this pressure supply line preferably opposite the cavity opening in the Cavity is introduced.

The fabric layer is preferably by means of holding devices in front of the open cavity side held. In a particularly preferred embodiment, the fabric layer is pre-tensioned the open cavity side and thus in front of the pressurizable pressure pad  held. This ensures in a simple manner that the fabric layer quickly and simply positioned on the slush skin and can be put on, so that a particularly good position-defined pressing and pressing of the fabric layer on the Slush skin is possible.

The holding devices are particularly preferred by the edge around the open Retaining webs spaced around the carrier device formed in which the free fabric layer ends are held. Those are preferred The ends of the fabric layer are threaded through the holding webs and held therein, so that these are kept out of the pressing area in a safe and simple manner. This is an overall high level of functional reliability when the fabric layer is pressed in given.

The object becomes with regard to the interior trim part with the features of the claim 15 solved.

According to claim 15, the reinforcement layer, preferably a fabric layer according to the Manufacture the slush skin and before connecting the slush skin to the backing layer a pressing device, the pressing surface conforming to the contour of the slush skin has, preferably by means of a hydraulic to increase the volume and / or pneumatically pressurizable airbag-like pressure pad into which Slush skin still in the gelled state is pressed in.

As has already been explained in detail above, such Interior trim part, in which the preferably designed as a fabric layer Reinforcement layer due to an even contact pressure through which the contour the contact surface of the pressing device that adjusts the slush skin is defined on dis Slush skin can be applied, the risk of detachment of the slush skin from the Fabric layer in the event of activation of an occupant protection device and one Moving the covering device away from the airbag outlet opening is considerably reduced because the tissue layer is particularly well anchored in the slush skin.

Basically, there are various options for designing the covering device, For example, such a covering device can be pivoted on Airbag outlet opening edge region hinged cover flap may be formed. Is preferred however, the cover device is formed by two cover flaps, each around an approximately opposite the border area of the two cover flaps and  swivel axis formed in the airbag outlet opening edge area as a cover flap Articulation point are pivotable. In the case of airbag activation, these are flaps then by means of a traction device inward behind the interior trim part to release the Airbag outlet opening pullable. With such a structure is a particularly fast and Easy opening and release of the outlet opening for the airbag achieved.

Basically, there are still various options for training the traction means. For example, the traction means, as initially mentioned in connection with the state of the Technology has already been explained in detail as tie rods with a Guide link mechanism to be trained. Alternatively, the use of Pull ropes conceivable. In a particularly preferred embodiment, the traction means at least partially formed by the free ends of the at least one fabric layer is connected to a component which can be moved back in the event of an airbag activation. In order to the fabric layer has an advantageous double function, which leads to a reduction in Component effort and overall leads to a relatively compact structure, because the Fabric layer on the one hand acts as a traction device and exerts a tensile force on the cover flap and on the other hand prevents the detachment of the slush skin. Furthermore, here can be relative elaborate traction means such. B. tie rods or the like, as separate components be saved.

Alternatively, the free ends of the at least one fabric layer can also be in the Region of the carrier layer, preferably on a stable inner skin of the carrier layer, be fixed, with the traction means then preferably also on the carrier layer the stable inner skin of the carrier layer.

The slush skin of the interior trim part can have one or more layers be built up, e.g. B. two layers with a surface layer and an underlayer. This is depending on the specific installation situation and the specific situation Design of the visible side of the interior trim part.

The carrier layer is preferably by a stable inner skin and a foam layer formed, the connection between the slush skin and the stable inner skin here then is made by the foam layer. For example, on the inner skin too Ribs and webs can be arranged with which the distance between the inner skin and the Outer skin is adjustable as a slush skin.

The invention is explained in more detail below with the aid of a drawing.

Fig. 12 is a schematic enlarged view of a portion of a fabric layer after putting on a slush skin and before fusing of the film with the slush skin, and

Fig. 13 is a fused with the slush skin in the nip film.

In Figs. 1 to 4, a process flow for manufacturing a trim part 1 for an automobile is shown schematically and by way of example schematically. As can be seen from FIG. 1, a slush skin 2 has been produced in a slush mold 3 , preferably an electroforming mold, which can be heated to a specific mold temperature, for which purpose a slush material has been introduced into the slush mold 3 , which material is obtained by rotating the slush mold 3 the heated mold surface is distributed and deposited and then sintered and gelled there.

In this gelled slush skin 2 is in a Slushhautbereich is to be formed in which a cover of an airbag outlet opening, mounted by means of a carrier device, a fabric layer 5 on the gelled slush skin 2 and subsequently formed by means of an integrally with the support device, the contour of the slush skin anpassendem, airbagartigem Pressing pad 6 is pressed into the gelled slush skin 2 with a uniform contact pressure in a defined contact area, as is shown schematically by the arrows in FIG. 2. This pressing and pressing process is shown in more detail in FIGS . 5 and 6 and in FIGS . 7 to 9.

In FIG. 5, the support device 4 is shown together with Pressure Pads 6, wherein the support device 4 includes a cavity open at one end 7 as a receiving space in which the Pressure Pads 6 is received. The fabric layer 5 is preferably held tensioned in front of the cavity opening by means of retaining webs 10 spaced at the edge around the cavity opening on the carrier device, the free fabric layer ends 8 , 9 being threaded through the retaining webs 10 . The holding of the free fabric layer ends 8 , 9 in the holding web 10 is shown here only extremely schematically and by way of example.

On the side opposite the cavity opening side of the support device 4, a compressed air line is guided in the cavity 7 11, wherein the Pressure Pads 6 is disposed around and fastened to the line opening this compressed air line 11, so that the Pressure Pads 6 at a compressed air in the cavity 7 is inflatable, such as this is shown schematically in FIG. 5 by the arrows 12 .

The cavity 7 is formed at least in the cavity opening area with such a geometry that the contact surface 13 of the contact pad 6 corresponds to the contact area 14 of the fabric layer 5 on the gelled slush skin 2 , as can be seen in particular from FIG. 6. Due to the pressure pad 6 adapting in its contour to the slush skin 2 , a uniform contact pressure of the fabric layer 5 on the gelled slush skin 2 is achieved, whereby the position-defined application of the fabric layer 5 is possible.

In Figs. 7 to 8 of the pressing process, as shown in FIGS. 5 and 6, again shown in detail in partial views, wherein it is apparent in particular from FIG. 8 that the Pressure Pads 6 for pressing on the opening edge portion 15 the cavity opening can protrude in order to achieve a defined indentation of the fabric layer 5 on the predetermined contact area 14 .

After pressing the fabric layer 5 by means of the pressure pad 6 , in the subsequent process step, as can be seen from FIG. 9, the carrier device 4 together with the pressure pad 6 is lifted off the slush skin 2 , so that the slush skin 2 for a firm anchoring of the fabric layer 5 can bake with this.

This state is also shown schematically in FIG. 3.

As can further be seen from FIG. 4, the slush skin 2 is subsequently connected to a carrier layer 16 in a subsequent method step. For this purpose, first a stable inner skin as part of this carrier layer 16 is introduced into the slush mold 3 at a distance from the slush skin 2 , the spacing preferably taking place via ribs formed on the inner skin. The area between the stable inner skin and the slush skin 2 is then foamed with a foam material, but this is not shown in detail here. However, the free fabric layer ends 8 before this foaming of the intermediate region between the stable inner skin and the slush skin 2, threaded through the stable inner skin of the carrier layer 16 9, so that these e.g. during assembly of the trim part 1 in the motor vehicle. B. can be connected to an airbag activation relocatable component of an occupant protection device. By moving the component back, a tensile force is then applied to the free fabric layer ends 8 , 9 , which simultaneously act as traction means, so that, for. B. in the case of two flaps, these can be pulled inward behind the interior trim part 1 , the risk of detachment of the slush skin 2 from the carrier layer 16 being considerably reduced by the firm connection of the slush skin 2 to the fabric layer 5 , so that no slush skin parts and possibly Foam parts can be carried by the inflating airbag in the direction of the vehicle interior towards a vehicle occupant.

Depending on the desired geometry of the cover flaps or the cover device Airbag outlet opening can additionally in the inner trim part in a manner known per se Target tear points are formed, e.g. B. by laser cutting. For example in the formation of two cover flaps in a middle border area as well  Such cuts are circumferentially made around a defined one Setting and specifying the opening behavior of the cover flaps. Such an incision can, for example, if necessary, at least the fabric layer cut through areas. The fabric layer shown in the figures is only here shown as an example and schematically. Depending on the covering device to be trained this fabric layer can of course be designed in different ways.

As can be seen further from FIG. 10, can on which the slush skin 2 remote from fabric layer side of an adapted in size to the contact surface of film 17, preferably a sheet 17 made of the same material as the slush skin 2, are applied. This is shown again schematically in cross section in FIG. 11 as section AA. In particular, it should be noted here that, for reasons of clarity, no device components are shown.

After the application of the film 17 , as can be seen in particular from FIG . B. with the pressure pad 6, a pressure is exerted on the film 17 together with the fabric layer 5 , as a result of which the slush skin 2 is placed on the gelled and thus still at an elevated temperature. The film 17 is then heated and melted by the heat given off by the slush skin 2 , so that it fuses with the slush skin 2 by embedding the fabric layer 5 in the pressing area, as shown in FIG. 13.
