Description
(54) MOTOR VEHICLE WALL CLADDING ELEMENT
(71) We, DYNAMIT NOBEL
AKTIENGESELLSCHAFT, a German Company, of 521 Troisdorf, Near Cologne,
Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to the production of a vehicle interior cladding element of a type particularly suited for use on an internal wall surface of a motor vehicle, either as a cladding element on a fixed body section or on a door.
Various techniques have been adopted in the automobile industry for the production of vehicle interior cladding elements. Such elements generally require the use of a surface covering material (decorative material) having a graining effect such as to simulate the appearance of leather. Foils used for this purpose are bonded to a support, for example by induction welding using usually a welding aid. Such a procedure therefore requires the provision of different covering materials for a range of vehicle model options and hence the keeping of an extensive stock of differently surfaced starting materials. Moreover, there is the risk that since the bonds between the supports and the covering material are only local, creases may be formed in the covering material, especially when there are marked temperature variations.
It is frequently desired that the covering should have a multi-colour effect. Covering materials are used in the automobile industry for this purpose which have the required multi-colour appearance and, in addition, a grainy surface appearance.
According to the present invention, there is provided a process for the production of a vehicle interior cladding element for use on an internal wall surface of a motor vehicle, which element comprises a support formed of a material which may be permanently deformed when subject to heat and pressure and a covering material comprising a polyethylene foam sheet and a plastics covering foil, wherein the polyethylene foam sheet of the covering material is applied to the support by coextensive surface-tosurface thermal bonding resulting from application of heat and pressure and, simultaneously with said bonding, a surface texturing structure is embossed ontothe plastics foil of the covering material and the support is shaped out of planarity. The term «embossing» is used herein to denote any process whereby a surface texturing, that is a surface profiling of very low relief is applied to the covering material and includes, in particular, the provision of a graining surface effect.
When employing the process according to the invention, a covering material is used which comprises a polyethylene foam preferably having a bulk density of at least 100 m3 /kg and especially a closed cell polyethylene foam, at least on its side facing the support, and in addition a plastics foil is laminated to the polyethylene foam. The foil is preferably an acrylonitrilebutadiene-styrene or polyvinylchloride foil which may be bonded to the polyethylene foam using an adhesive, for example a polyurethane-based adhesive. Polyethylene foils can also be used; these can be bonded to the polyethylene foam at the time of bonding the latter to the support. In bonding the covering material to the support, it is no longer necessary to employ a welding aid since a surface-to-surface union between support and covering material, that is a genuine composite material, is produced by thermal bonding. This is not effected in a separate additional working step, but simultaneously with the provision of a surface texture to the covering material, for exam ple a graining, by embossing. Hence, it is not necessary to keep a stock of materials of different surface structure. At the same time, the support is shaped out of planarity by means of a heat-embossing press used for producing the aforesaid bonding and embossing, provided that the mould parts are suitably shaped. For example, shaping may be carried out concomitantly with embossing and bonding in a development of the so-called «Press-Tock» process of
Deutsche Pres-Tock GmbH and Co. KG which was originally developed as a procedure for producing shaped parts from flat mats formed of wood fibre-reinforced synthetic resins. In the Pres-Tock process, the flat mats are steam treated to render them deformable and then shaped under suitably controlled conditions of temperature, pressing pressure, pressing speed and pressing time in a mould a part of which may have a textured surface to ensure that the shaped product obtained has a corresponding textured surface.
If the upholstered element is to have a multi-colour surface appearance in addition to graining, then the graining material can be drawn off as a multi-coloured sheet from a supply reel. The limits or boundaries between colour regions of the covering material will in this case extend in the withdrawal direction. Deviations in the path of these colour limits can be corrected by applying decorative strips to the covering material.
Such problems in maintaining a sufficiently accurate alignment of these colour regions can occur more especially in the region of constrictions or channels in the support and irrespective of whether the support has already been rendered non-planar before applying the covering material or, as just described, the shaping of the support is effected in the same working step, whereby the required surface-surface bond and embossing are produced. In this case, the working tool used must push or draw the covering material into the channel. It may be expedient to provide the various colour regions juxtaposed with respect to each other by overlapping separate colour sheets or strips.
For a better understanding of the invention and to show how the same can be carried into effect, reference will now be made by way of example only to the accompanying drawing, which is a cross-section through an inside lining or facing for a door of a motor vehicle as produced by the process of this invention.
Referring to the drawing, the lining or facing comprises a support 1, which in this case is shaped out of planarity as at 2 and which consists of a material which can be deformed by using heat and pressure. For example, the support can be formed of cardboard, polypropylene with a sawdust filling of up to about 70% by weight, fibrid material, parchment paper or phenolic resin-bonded cotton fibres.
A multi-coloured covering material 3 is applied to the support. The covering material comprises a polyethylene foam layer on its surface facing the support, the foam layer preferably having closed cells, and additionally comprises a plastics foil over its other surface. A surface-surface bond has been produced between the parts 1 and 3 in a single working step and in which the support 1 has been shaped out of planarity and a surface structure has been given to the exposed free surface of the covering mater ial 3.
The foil comprised by the covering material is a multi-coloured sheet having, for example, dark colour regions at 4 and 5 and a light colour region at 6, as shown in the drawing. Dislocations in the iuxtaposition of colour regions 4, 6 and 5, 6 and especially the boundaries thereof are disguised by provision of decorative strips 7 and 8 which are provided at the critical positions, that is in the channels between the colour regions 4 and6and5and6.
The process of this invention can also be used when additional foam material strips are to be fitted and secured at «thick» positions, that is at 9 in the constructional example which is shown in the drawing. It is particularly when a water-repellent material is used for the support 1, that it is desirable to use a foam material having closed cells in order to ensure that water retention does not occur.
The edges of the covering material can be drawn around the edges of the support 1 and welded to the latter, and this can likewise take place in the single aforesaid working step. This working step is effectively a heat lamination procedure effected at temperatures usually from 150 to 1800C, and preferably around 1600C and at pressures preferably around 5 kg/cm2. The pressure emp lowed depends more especially on the supporting material and the thickness of the support.

A process for the production of a vehicle interior cladding element for use on an internal wall surface of a motor vehicle, which element comprises a support formed of a material which may be permanently deformed when subject to heat and pressure and a covering material comprising a polyethylene foam sheet and a plastics covering foil, wherein the polyethylene foam sheet of the covering material is applied to the support by coextensive surface-tosurface thermal bonding resulting from application of heat and pressure and, simultaneously with said bonding, a surface tex

At the same time, the support is shaped out of planarity by means of a heat-embossing press used for producing the aforesaid bonding and embossing, provided that the mould parts are suitably shaped. For example, shaping may be carried out concomitantly with embossing and bonding in a development of the so-called «Press-Tock» process of Deutsche Pres-Tock GmbH and Co.

If the upholstered element is to have a multi-colour surface appearance in addition to graining, then the graining material can be drawn off as a multi-coloured sheet from a supply reel. The limits or boundaries between colour regions of the covering material will in this case extend in the withdrawal direction. Deviations in the path of these colour limits can be corrected by applying decorative strips to the covering material. Such problems in maintaining a sufficiently accurate alignment of these colour regions can occur more especially in the region of constrictions or channels in the support and irrespective of whether the support has already been rendered non-planar before applying the covering material or, as just described, the shaping of the support is effected in the same working step, whereby the required surface-surface bond and embossing are produced. In this case, the working tool used must push or draw the covering material into the channel. It may be expedient to provide the various colour regions juxtaposed with respect to each other by overlapping separate colour sheets or strips.

For example, the support can be formed of cardboard, polypropylene with a sawdust filling of up to about 70% by weight, fibrid material, parchment paper or phenolic resin-bonded cotton fibres. A multi-coloured covering material 3 is applied to the support. The covering material comprises a polyethylene foam layer on its surface facing the support, the foam layer preferably having closed cells, and additionally comprises a plastics foil over its other surface. A surface-surface bond has been produced between the parts 1 and 3 in a single working step and in which the support 1 has been shaped out of planarity and a surface structure has been given to the exposed free surface of the covering mater ial 3. The foil comprised by the covering material is a multi-coloured sheet having, for example, dark colour regions at 4 and 5 and a light colour region at 6, as shown in the drawing. Dislocations in the iuxtaposition of colour regions 4, 6 and 5, 6 and especially the boundaries thereof are disguised by provision of decorative strips 7 and 8 which are provided at the critical positions, that is in the channels between the colour regions 4 and6and5and6.
