Description

Technical area

The invention relates to a fitting for a vehicle, in particular for a motor vehicle, with a carrier and a foamed insert, wherein the insert has fastening elements for fixing to the carrier.

State of the art

In particular, interior components for motor vehicles, such as door panels, center consoles or instrument panels, have a layer structure of a carrier, a decor and a foam layer arranged therebetween. This foam layer serves as a haptic layer to achieve a pleasant, soft touch on the surface of the interior component.

The production of this layer structure can be realized by means of a direct foaming of the foam layer on the support and a subsequent lamination with a decorative layer. An inexpensive alternative is to use foam inserts as a foam layer, which are produced in a separate foaming process and then placed on the support. In the subsequent lamination process with the decorative layer, however, there is a risk in this process of unwanted marks on the surface due to slippage or pushing away of the foamed insert. So far, this problem has been avoided by an additional, costly and material-intensive manufacturing step, for example, the gluing of the insert with the carrier.

Description of the invention

The object of the invention is to provide a piece of equipment with foamed inserts available. In the production of the equipment part is dispensed with an additional, costly and material-intensive adhesive process and allows direct mounting of the insert on the carrier.

This object is achieved by the component according to claim 1. Advantageous embodiments follow from the subclaims and the described preferred embodiments.

The component according to the invention is an equipment part for a vehicle, in particular a motor vehicle, consisting of a carrier made of a rigid and / or elastic material and a foamed insert disposed thereon, and preferably a decorative layer arranged thereon, for example laminated or is padded. The decorative layer may be a foil or a dermis.

In a preferred embodiment of the equipment part of the insert itself forms the decorative surface, for example, the insert consists of an integral foam, or is provided before fixing to the support with a decorative layer.

The foamed insert is configured with a plurality of fastening elements for fixing on the carrier, wherein the fastening elements are formed integrally therewith in the manufacturing process of the insert. It is preferably no adhesive for connecting carrier and insert used. Rather, the connection is only positive and / or non-positive.

The insert consists of a foam system. The foam system may be a foamable system of suitable materials (e.g., (bio) polymers) in a chemical or physical foam process.

As the chemically foamed system, a two-component system is preferable, especially a polyurethane foam system. To shape the insert, the foam system is foamed, for example, in a foaming mold from a top and bottom tool. Both tool halves are equipped in the parting plane with a sealing surface, which seal at a suitable internal pressure. The venting of the resulting reaction gases also takes place via this parting line. In the foam mold, the insert receives the outer shape for placement on the carrier and is designed simultaneously with the fastening elements for fixing to the carrier.

The support may be made of a rigid material, preferably polypropylene, acrylonitrile-butadiene-styrene or other suitable plastic, preferably made by injection molding. However, fiber-reinforced plastics or compressed fiber mats made of natural and / or artificial fibers as support materials are also conceivable. Also carriers of flexible materials and / or of several rigid materials, which allow an articulated configuration of the carrier conceivable.

In the embodiment of the carrier recesses for receiving the fastening elements are provided, for example in the form of grooves, holes or columns.

The fasteners of the insert consist of a first section, which passes through the carrier from the front to the insert is arranged extends to the back, and a second portion which protrudes from the back of the carrier.

The first section is used for fixing or fitting the mounting position of the insert in a direction parallel to the plane spanned by the carrier and the second section is used for fixing in a direction perpendicular to the carrier. This results in a complete determination of the insert relative to the carrier. The fastening elements preferably have an undercut form, that is to say the width of the second section of the fastening element is at least partially greater than the width of the first section.

The minimum width of the first section must allow sufficient stability of the fasteners and sufficient fixation on the carrier. A depth is greater for this first portion of the fastener, in particular equal to the depth of the recesses of the carrier. That is, the first portion lies partially, in particular completely, in the recesses of the carrier.

Preferably, the width of the first portion of the fasteners is less than the average depth of the insert. Preferred for the first section are cylindrical or cuboidal configurations. A possible embodiment for the shape of the first section is a kind of bridge. The cross section of this first section preferably corresponds to that of the recesses in the carrier in order to realize a snug fit of the fastening elements.

Preferably, the second portion of the fastener tapers towards the end to allow for easier pushing of the fasteners in fixing the insert to the carrier. In a preferred embodiment, the second portion of the fastener has a mirror-symmetrical, in particular a spherically symmetrical shape. Conceivable, for example, second sections in the form of cylinders, prisms, spheres or pyramids.

An alternative embodiment provides for the second portion of the fasteners before a configuration that allows folding the fasteners on the back of the carrier. Conceivable is a kind of narrow web, for example in the form of a film hinge, at the transition to the first section whose width is smaller than the remaining part of the second section. After pushing the fasteners through the recesses of the carrier, pressure is exerted on the fasteners, so that they fold over the narrow web. Subsequently, the folded-over second sections of the fastening elements can be fastened in a suitable manner to the rear side of the carrier, for example by latching, bracing or gluing. Preferably, in this case, corresponding counter means in the form of latching or clamping means or defined adhesive surfaces are provided on the back of the carrier.

The shape and size of the fasteners may each be the same, different or in groups the same. The number of fasteners of an insert is also variable. Depending on the size and design of the carrier, for example, several small or few large fasteners are useful. Optimally, the position and size of the fasteners is suitably adapted to the shape of the carrier and the best possible fixation of the insert on the carrier. Preferably, a different arrangement and shape of the fasteners for different equipment parts is provided in order to avoid a risk of confusion when fixing the insert to the carrier, for example in equipment for left and right-hand drive. Preferably, the shape of the insert and / or support supports the impressions and fixation of the fasteners. It is conceivable, for example, a kind of channel in the carrier on the recesses for receiving the fasteners, in which the equipped with a matching rib for receiving the insert is pressed.

In a preferred embodiment, the edge regions of the insert are designed such that they can be inserted into the carrier, which is provided with a suitable groove. As a result of the manufacturing process of the insert, air pockets and defects may form, especially at the edge region. For example, caused by the vent during foaming unwanted foam films at the edge of the insert. By sinking or pushing the edge region in the carrier these undesirable impairments of the insert are hidden, so that can be dispensed with an additional post-processing of the insert. In addition, insertion into this groove makes it possible to stabilize the insert during the transition from the support to the soft insert, so that displacement of the support in the edge regions is avoided and additional simplification of the subsequent laminating process with a decorative layer can be achieved.

At the carrier 2 it is a plastic carrier, manufactured by injection molding. As foam material for the depositor 3 polyurethane foam is provided. The depositor 3 is manufactured in a foaming process known from the prior art, separately from the carrier 2 ,

After curing of the foamed insert 3 the fixing takes place on the carrier 2 by removing the fasteners 6 through the recesses 5 be pushed ( 1b ).

As in 1b shown, the recesses run 5 through the entire depth of the carrier 2 and have a thin groove shape. The fixing of the insert takes place under external pressure, wherein the soft foam material of the fastening elements 6 slightly deformed and through the recesses 5 lead. The undercut shape of the fasteners 6 prevents loosening of the inserter 3 from the carrier 2 at the following processing steps and holds the depositor 3 in a defined position on the carrier 2 ,

The fasteners 6 consist of a first section 61 , which at one on the carrier 2 fixed depositors 3 through the recesses 5 of the carrier, and a second section 62 that's over the back 22 of the carrier 2 protrudes. The first paragraph 61 serves to fix the inserter 3 in a parallel direction 23 to the front 21 of the carrier 2 and the second section 62 for fixing in a direction perpendicular thereto 24 ,

The shape of the first section 61 is like a cuboid bridge, which in the recesses 5 of the carrier 2 fits. The depositor 3 is with two different sets of fasteners 6 formed, whose second section 62 on the one hand has a cylindrical shape and on the other hand, a prism with a trapezoidal base resembles.

The first paragraph 61 is designed in the form of a bridge or cylinder, which fits perfectly with the recesses 5 of the carrier 2 concludes. The depth of the recesses 5 of the carrier 2 is equal to the depth of the first section 61 , The width of the second section 62 is at least partially greater than the width of the first section 61 ,

In the 2a -C are different shapes for the second section 62 the fasteners 6 illustrated. A rotationally symmetrical shape is in 2a represented, which can be cylindrical or ball-like. The mirror-symmetric shape, shown in 2 B , corresponds to that of a prism with a trapezoidal base. Conceivable here is of course also a geometry in the form of a truncated pyramid or an arrowhead. The second section 62 a fastener 6 in 2c does not have a symmetrical shape. The shape is similar to that of a prism with an irregular base, or a latching hook.

The variant in 2d includes in addition to the design of the fasteners 6 at the depositor 3 another shape in the form of a rib 7 , The carrier 2 is structured so that this rib is picked up. A kind of channel in the vehicle 2 offers a possibility. This additional rib facilitates the impressions of the fasteners 6 in the carrier 2 and improves the fixation of the inserter 3 on the carrier 2 , This can be the rib 7 in its longitudinal extent parallel to the front of the carrier 21 one or more fasteners 6 exhibit.

In 3 is a schematic sectional view of an equipment element 1 with a carrier 2 and a foamed inserter 3 shown. The arrangement of fasteners 6 at the depositor 3 is the structure of the vehicle 2 customized. Ideally, the fasteners lie 6 between existing undercuts or bulges in the carrier 2 , 3 shows next to the fasteners 6 border areas 9 of the depositor 3 , which are designed in a suitable manner for receiving the carrier. For this recording are grooves 8th in the carrier 2 intended. The border areas 9 in the grooves 8th provide additional fixation of the soft insert 3 at the transition to the carrier 2 ,
