Abstract

A method for forming an embossed mark (14) on a cover (10) of a vehicle seat (1), wherein according to the method in a first step on the left side of the intended for the mark (14) location of the cover (10) a lock lining ( 16), in a second step the mark (14) is embossed in the cover (10) and in a third step the three-dimensional shape of the mark (14) is fixed by sliding the lock lining together with the left side of the cover (10 ) is treated in the region of the mark (14) with a lacquer (L), wherein the existing of an absorbent material barrier lining (16) partially absorbs the paint (L), which then hardens.

Description

The invention relates to a method for forming an embossed mark having the features of the preamble of claim 1.

When embossing three-dimensional shape tags into a leather-covered trim for a vehicle seat, the problem is that the leather is slowly approaching its original shape, making the brand flatter. Therefore, in a known method, the mark on the left side of the cover is filled with silicone, which fixes the three-dimensional shape after drying. However, the silicone takes several hours to cure, forms an unpleasant odor during processing and may not be used in some cases in the vehicle interior. Such a method is known from KR 1019920005679 B1 known.

From the DE 40 10 872 C2 a method is known in which the three-dimensional shape of the mark is fixed, wherein the cover is coated on one side with a thermoplastic material. From the AT 001 532 U1 It is known to coat the three-dimensional shape of the mark with a polyurethane foam or rubber. The JP 2000104100 A describes the fixing of the three-dimensional shape of the mark with a two-sided coating with synthetic resin. The attachment of a surface element of a polar, forming during embossing plastic is in the DE 10 2004 047 667 A1 described. The sticking of a lamination, z. B. fabric cloth on the back to prevent the warp of the embossing is in the DE 17 22 132 U disclosed.

The invention is based on the object to improve a method of the type mentioned. This object is achieved by a method with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

The fact that the left side of the cover in the region of the mark is treated with a lacquer for fixing the three-dimensional shape of the mark, this process step requires significantly less time, especially if the paint cures quickly. For example, only a few minutes instead of several hours as in the case of silicone needed. The paint is preferably applied quickly by spraying it on. Alternatively, the paint can be applied with a brush. As a paint, in principle, any commercially available, film-like coatable and curing coating material can be used, whether on a solvent basis or by utilizing a polymerization, provided that it is approved for the vehicle interior. In the most general case, the "paint" may also be a curing adhesive or a corresponding resin.

In order to improve the shape-stabilizing effect of the paint and to protect the cover as possible, a lock lining is mounted, for example glued, which is preferably thin-layered, so as not to apply, and before the stamping on the left side of the mark provided for the reference point of the cover has a size slightly larger than the brand to also fix the edge next to the mark. The chuck then becomes part of the cover. The barrier liner is treated with the coating along with the cover to enhance the fixation of the three-dimensional shape. A so-called non-woven fabric or other absorbent material takes up the paint partially. During curing, this contributes particularly well to fixing the three-dimensional shape of the mark.

The usual for the further processing of the cover lamination is then applied after the fixation on the left side of the cover, preferably glued, thereby covering the fixed left side of the mark. However, the lamination does not affect the three-dimensional shape of the mark and is therefore optional.

The method is particularly well suited for covers made of leather, but could theoretically also be used for synthetic leather or fabrics with similar properties. It is not limited to vehicle seats and can also be used for other saddlery products.

In the following the invention with reference to an embodiment shown in the drawing is explained in more detail. Show it

1A a first step of attaching a barrier liner to the cover,

1B a second step, in which the mark is embossed in the cover,

1C a third step, in which the cover is treated with lacquer,

1D a fourth step, in which the lamination is attached to the cover,

1E a section through the vehicle seat in the area of the brand, and

2 a perspective view of the vehicle seat.

A vehicle seat 1 is intended as a front seat for a motor vehicle. The vehicle seat 1 is designed as a sports seat with a contoured, one-piece (or two-part) shell 5 as a supporting structure, for example made of carbon fiber reinforced plastic, one of the shell 5 included upholstery 7 , for example, foam, and one over the pad 7 tense and on the edge of the shell 5 fixed cover 10 on the passenger facing the front of the vehicle seat 1 , In conventional designation is the occupant facing side of the cover 10 as the right side, the side facing the upholstery referred to as the left side. The reference 10 is made of leather. On the left side of the cover 10 is a lamination 12 applied from a thin foam layer, with which together the cover 10 on the padded shell 5 is attached.

The reference 10 carries a mark on its right side in an exposed place 14 which is an integral part of the cover 10 is and is raised above its environment, so is three-dimensional. The term "brand" should also be understood to mean other signs, coats of arms or ornaments.

For the production of the brand 14 on the cover 10 in a first step ( 1A ) on the left side for the brand 14 intended place of reference 10 a chuck 16 attached, glued here. For example, adhesive is applied locally to the cover 10 painted and the chuck 16 then pressed. The lock lining 16 becomes thereby a component of the reference 1 , The lock lining 16 has one opposite the brand 14 slightly larger size and consists of a thin-layer, absorbent material, in this case a so-called non-woven fabric.

In a second step ( 1B ) becomes the brand 14 in the reference 10 impressed, wherein from the left side a stamp with the raised image (male P) and from the right side a stamp with the recessed image (die M) on the relevant point of reference 10 acts. The lock lining 16 When embossing takes the shape of the brand 14 at.

In a third step ( 1C ) becomes the left side of the cover 10 at the point concerned, together with blocked feed 16 sprayed with a varnish L, which dries quickly and thus the three-dimensional shape of the brand 14 fixed.

In a fourth step ( 1D ) becomes the lamination 12 on the left side of the cover 10 attached, for example by adhesive over a large area on one side of the lamination 12 is sprayed on and then the lamination 12 with the adhesive coated side on the cover 10 is pressed on the left side. This will make the lock lining 16 covered.

The thus prepared cover 10 is in a conventional manner when assembling the vehicle seat 1 used ( 1E ).
