BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an Upholstery element with a covering which covers a core of an elastic material, preferably of a foamed plastic, and is fastened to this core by an anchorage element which is enclosed by the core, and to a method for the production thereof.
BACKGROUND OF THE INVENTION
Upholstery elements, for example for the interior furnishing of motor vehicles, generally consist of an elastic core whose surface is completely or partly covered by a covering, for instance of cloth, leather or similar, for protective and aesthetic purposes. Foamed plastics, preferably polyurethane, are in particular used as the core material, occasionally also vegetable or animal fibres bonded together. In order to ensure that the covering holds firmly to the core, anchorage elements enclosed by the core material are commonly used in the prior art to distribute stresses occurring due to force over a large area. The utility model DE 295 06 306 discloses an example of an anchorage element in the form of a profile which can be foamed into a core. The particular advantage of the described anchorage element lies in the fact that, with the exception of a network of fibres, it consists of polyurethane, so that it is far easier to recycle the upholstery material as a result of using a uniform material and avoiding metal parts. The anchorage elements are joined to the covering by fastening means, for example hooks, which pass through the foamed plastic which is frequently provided with recesses for this purpose.
The anchorage elements known in the prior art entail high expenditure when producing the upholstery, with the clamping of the covering and the anchorage elements and the positioning thereof in the foaming mould in particular being labour-intensive. Moreover, there is a permanent join between the core of the upholstery and the covering, so that it becomes far more difficult to replace the latter should it wear or for aesthetic reasons.
OBJECT OF THE INVENTION
Against this background, the object of the invention is to develop an upholstery element in which the expenditure for anchoring the covering is reduced and the latter can be replaced without undoing permanent joins.
This object is achieved according to the invention in that the surface of the core comprises a groove which widens inwards, one edge of a material strip is fixed to the inside of the covering, the opposite edge of which strip is provided with a dimensionally stable body, the body is introduced into the groove, and the maximum diameter of the body is located in the groove and is greater than the minimum diameter of the groove.
DETAILED DESCRIPTION OF THE INVENTION
The surface of the core of the proposed upholstery element comprises a groove in the form of a hollow section which widens at the bottom, i.e. towards the interior of the core. A preferably profiled body is located in the groove, the maximum diameter of which body is disposed in the groove and is greater than the minimum diameter of the latter. The narrowest region of the groove is appropriately its opening. As a result, the dimensionally stable body can only be positioned in the groove and withdrawn from the latter by deforming the elastic core material. The spring force exerted by the core material in this case makes the body sit firmly in the groove. Dimensional stability of the body is only required for sufficient anchorage, so that its inherent elasticity can correspond perfectly well to that of the core material.
The join between the covering and the body is effected by a material strip, which may also be a component of the latter. Appropriate material strips are those which consist of a flexible material, for example netting or a woven fabric, which are fastened at the edge to the inside of the covering, e.g. stitched thereto. The groove is preferably filled by a single body in the form of a profile, with the material strip being joined to the body and the covering along its longitudinal sides. It is alternatively possible to introduce a plurality of b
