This application claims priority under 35 U.S.C. ยง 119 from German Patent Application No. 102022108220.2, filed Apr. 6, 2022, the entire disclosure of which is herein expressly incorporated by reference.
The present invention relates to a cladding part having a textile covering.
In contemporary vehicle construction, surfaces in the vehicle interior or in the passenger compartment of motor vehicles are provided with decorative elements in order to create an appealing visual impression for the occupants of the vehicle. For the interior trim parts, or cladding parts, there is a multiplicity of surface variants (leather, artificial leather, films, textiles) that are applied to a carrier by various laminating methods. At present, for laminated interior trim parts, e.g. a knitted spacer fabric, a foam backing or nonwoven fabric is used as a haptic layer. In this context, it has become customary to adhesively bond decorative elements, for example in the form of films with the visual appearance of wood or carbon, to a plastic carrier. In addition, it is also known to mount skins of leather or artificial leather on carrier structures using laminating methods, e.g. press laminating methods or similar laminating methods, e.g. without a fixed upper tool, in order to create the visual appearance of leather. In the course of this laminating operation, the films or the skins are materially bonded to the underlying carrier structure using an adhesive. The heat needed to activate the adhesive is introduced into the adhesive joint through the skin via a hot press die of the press laminating tool by way of contact heat or by means of IR radiation. This activates the adhesive during the laminating method and connects the film or the skin to the carrier structure.
Many of these surfaces, however, have restrictions in terms of the possible uses of the cladding parts in the vehicle interior owing to the materials used and owing to the production method used.
US 2016/0229338 A1 discloses the provision and backlighting of cladding parts with a knitted surface.
DE 198 55 540 A1 discloses a seat covering in which different additional functional elements are integrated.
DE 198 47 333 A1 discloses a method for producing knitted fabrics with integrated fastening elements.
Taking this prior art as a starting point, the object of the present invention is to provide a cladding part which overcomes the disadvantages of the prior art. It is a particular object of the invention to provide a cladding part which is distinguished by good ergonomic properties.
This object is achieved by a cladding part according to the features of the independent claim. Further embodiments are specified in the dependent claims.
To achieve this object, the invention proposes a cladding part having a textile covering, the covering forming a visible surface of a wall. Suitable textiles in this context are in particular knitted-fabric material, woven-fabric material, stitch-bonded-fabric material, mesh material, etc. The covering can have at least one wall portion which can be transferred into a position in which the wall portion forms at least one outer wall region of a receptacle, or a cavity, or an indentation. Forming the wall portion from textile offers the advantage over placement surfaces of hard plastic that it is possible to realize a flexible surface offering ergonomic advantages. This flexibility of the textile also leads to a reduction in the risk of injury to the occupants of the vehicle in the event of a crash, since a textile storage compartment is considerably more flexible, or deformable, than a storage compartment of hard plastic with inflexible contours.
Furthermore, the wall portion may be transferable into a position in which the cladding part does not have a receptacle, or cavity, or indentation. In other words, in this position, the wall portion is in a folded-in state, so that it does not form a receptacle, or a storage compartment. This makes it possible to free up more interior installation space and thus improve the space conditions, which are always very limited. This relates in particular to use cases in which the cladding part is in the form of door cladding, in the case of which the placement surface usually penetrates the footwell of the driver or front-seat passenger.
The wall portion may be transferable from a first position in which the wall portion forms at least one outer wall region of a receptacle, or a cavity or an indentation, into a position in which the cladding part does not have a receptacle, or cavity, or indentation, and vice versa. In other words, the outer wall region of the covering can be folded out, so that it forms at least one outer wall region of a storage compartment. The wall portion can be folded open into a first position in which it encloses a receptacle, a cavity, an indentation, or a storage compartment, at least in certain portions. This offers the advantage that the receptacle can be used as a storage compartment when required. However, the wall portion can also be folded in, so that it does not form a storage compartment. Therefore, the loss of installation space, for example in a vehicle interior, is reduced to the cases in which it is actually necessary to use a storage compartment.
The surface covering may be formed from a textile throughout, with not just the wall portion but also the surrounding regions of the covering being formed from textile. This offers the advantage that the interior decoration in the vehicle interior is continuous and thus forms a homogeneous, visually extremely appealing appearance.
Furthermore, the wall portion may have a stiffening. The stiffening exerts a force on the wall portion which keeps the wall portion in a folded-in state. In a folded-out state, the stiffening exerts a force on the wall portion which keeps the wall portion in an open state.
Furthermore, the wall portion may have a stiffening in its end which is uppermost counter to gravitational force. This offers the advantage that the upper terminating edge of the wall portion is formed with a stiffening, which shapes the contour of the wall portion. In a folded-out state, in which a storage compartment is formed, it is consequently possible to form a dimensionally stable opening in the storage compartment with improved engagement. The contour-defining stiffening element, however, also offers the advantage that the opening and closing of the storage compartment, i.e. the folding-out and folding-in of the wall portion, are made easier.
As an alternative, the stiffening may be applied partially or else to the entire surface area of the wall portion, with the result that the restoring effect can result not only from a partial region at the upper end of the wall portion but from the entire surface area of the wall portion.
In all the alternatives mentioned, the stiffening may be in the form of a mesh, or mesh woven fabric, or a leaf spring.
The textile may have sufficient intrinsic stability, or stiffness. This offers the advantage that, in the folded-in state, the wall portion closely follows the carrier structure of the carrier part in a dimensionally stable manner. In the folded-out state, the intrinsic stability offers the advantage that a desired form of the outer wall is maintained by the textile.
In addition, an illumination device that emits light may be provided. In a position in which the cladding part does not have a receptacle and therefore the wall portion is in a folded-in state, the wall portion may be translucent. In this way, it is particularly easily possible to backlight the passenger compartment, what is referred to as ambient lighting.
Furthermore, it is possible for the wall portion to not be translucent in a position in which the wall portion forms at least one outer wall region of a receptacle, or cavity, or indentation. This offers the advantage that the illumination device is used as lighting for the storage compartment. By reducing the translucent properties of the outer wall region, or of the wall portion, it is possible to have the effect of increasing the brightness inside the storage compartment.
Of course, as an alternative, it is also possible for the outer wall region to continue to be translucent even when the wall portion is in a folded-out position. This makes it possible not only to achieve good illumination of the inner region of the storage compartment, but also to backlight the passenger compartment at the same time.
The cladding part is preferably an interior component for the vehicle interior of a vehicle, such as instrument panels, door claddings, claddings for the A pillars, B pillars, etc., sunshades, back seat area compartments, arm rests, central consoles, closable storage compartments such as glove boxes, etc. Glove boxes may be provided with cladding both on the outside and inside. However, the cladding part may also be used to clad seats and/or headrests. Therefore, 2D/3D knitted fabrics can be used as interior surfaces that have a decorative seam integrated during the knitting process for the purpose of creating a component.
However, the cladding part may also be used for other means of transport, such as aircraft, ships, trains etc. The use of the cladding part in furniture or furnishings is also contemplated.
A knitted material, or knitted fabric, should be understood to mean a sheet-like textile in the context of the invention. The knitted fabric is preferably formed from a front-side knitted fabric and a back-side knitted fabric, the front-side knitted fabric and the back-side knitted fabric preferably each being produced from a yarn or monofilament. The yarn according to the invention is, in turn, formed from a multiplicity of filaments. For example, a yarn comprises 50 to 100, in particular 70, filaments. The filaments are preferably manufactured from a plastic and/or aramid and/or a similar material. A 3D knitted fabric is manufactured in a three-dimensional manner by way of its special production process and consequently differs from a two-dimensional, flat knitted fabric both in terms of handling and manufacturing and the requirements for fastening and processing. A 3D knitted fabric is generally manufactured for the covering over a carrier component and advantageously enables processing with reduced offcuts or even without offcuts.
The advantages of the invention are to be briefly summarized below. By replacing the previously known plastics components with textile composite materials, in particular textiles, it is possible to realize flexible component surfaces. The use of textiles with intrinsically stiff properties makes it possible to largely dispense with the use of an underlying substrate. Its intrinsically stable properties enable the knitted fabric to span regions of the substrate in which the substrate has openings or apertures, without the edges of the openings being reproduced on the surface of the cladding part, or the knitted fabric. The saving on component materials for the substrate thus leads to a reduction in the overall weight of the cladding part. Using the textiles, it is possible to present high-quality surface materials without an underlying carrier structure, or without an underlying substrate. Advantages result not least for the production of the cladding part according to the invention, because the manufacturing process is facilitated. In particular, there are no preliminary processes for the component manufacture, because, for example, the production of the substrate is made easier. When textiles with intrinsically stiff properties are used, it is possible to save on a deposition of adhesive to bond the substrate to the covering and thus the laminating of the substrate to the covering forming the surface can be made easier.
In particular, the receptacle, cavity, indentation, or placement surface within the meaning of this invention can be understood as meaning in particular map pockets, bottle holders, pockets, flaps, bags/pouches for small parts and similar depressions.
Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of one or more preferred embodiments when considered in conjunction with the accompanying drawings.
The wall portion 11 is flexible and can be folded in, so that it is transferred into a position depicted in
