COVER FOR A SEAT AND METHOD FOR PRODUCING A COVER
A cover ( 1 ), in particular a backrest cover or a lateral cover for a vehicle seat, is molded from a covering material layer ( 2 ), in particular from a covering material blank ( 2.1 ) and from a carrier material layer ( 4 ), in particular from a carrier material blank ( 4.1 ). An adhesive non-woven ( 3 ) or an adhesive layer is disposed between the covering material blank ( 2.1 ) and the carrier material blank ( 4.1 ).
1 . A vehicle seat backrest cover or vehicle seat lateral cover, comprising:
a covering material layer provided from a covering material blank;
a carrier material layer provided from a carrier material blank; and
an adhesive layer comprising an adhesive non-woven disposed between the covering material layer and the carrier material layer, wherein the covering material blank and the carrier material blank are molded together with the adhesive non-woven disposed therebetween.
2 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein a covering material of the covering material layer, and a carrier material of the carrier material layer are joined to one another by the adhesive layer by a pressure-forming and pressure joining method.
3 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the covering material and the carrier material are joined to one another by the adhesive layer by a pressure-forming and pressure-joining method by applied high frequency energy.
4 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the covering material is a vinyl material, a textile material, or a natural material.
5 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the carrier material is a carrier non-woven comprising a press felt or press non-woven.
6 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the adhesive non-woven is a co-polyester non-woven or a thermoplastic non-woven.
7 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the cover has a thickness in a range from 3 mm to 5 mm.
8 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the cover has a thickness in a range from 4.0 mm to 4.5 mm.
9 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the cover has a hardness of more than 60 Shore-A in with the carrier material layer comprising a 1000 g carrier non-woven.
10 . A vehicle seat backrest cover or vehicle seat lateral cover according to claim 1 , wherein the cover has a three-dimensional shape comprising a shell shape.
11 . A method for producing a vehicle seat backrest cover or vehicle seat lateral cover comprising a covering material layer provided from a covering material blank, a carrier material layer provided from a carrier material blank and an adhesive layer comprising an adhesive non-woven disposed between the covering material layer and the carrier material layer, the method comprising the steps of:
opening a forming and joining unit comprising at least one positive mold part and one negative mold part;
positioning the carrier material blank and the covering material blank, with an adhesive non-woven or an adhesive layer disposed therebetween, on one of the mold parts in the opened forming and joining unit;
closing the forming and joining unit by moving the negative mold part in the direction of the positive mold part, or vice versa;
joining the covering material blank to the carrier material blank by means of the adhesive non-woven by welding and molding the cover by pressure forming; and
opening the forming and joining unit and removing the molded cover.
12 . A method according to claim 11 , wherein the covering material and the carrier material are joined to one another by the adhesive layer by the pressure-forming and pressure joining method by applied high frequency energy.
13 . A method according to claim 11 , wherein the covering material is a vinyl material, a textile material, or a natural material.
14 . A method according to claim 11 , wherein the carrier material is a carrier non-woven comprising a press felt or press non-woven.
15 . A method according to claim 11 , wherein the adhesive non-woven is a co-polyester non-woven or a thermoplastic non-woven.
16 . A method according to claim 11 , wherein the cover has a thickness in a range from 3 mm to 5 mm.
17 . A method according to claim 11 , wherein the cover has a thickness in a range from 4.0 mm to 4.5 mm
18 . A method according to claim 11 , wherein the cover has a hardness of more than 60 Shore-A in with the carrier material layer comprising a 1000 g carrier non-woven.
19 . A method according to claim 11 , wherein the cover has a three-dimensional shape comprising a shell shape.
