Abstract
Abstract A seat (1), in particular for vehicles, with foamed plastic padding (4, 5), has a supporting body (7) made of an open-cell elastic foamed plastic having a first specific gravity. A flame-retardant layer (12) made of an open-cell elastic foamed plastic having a second specific gravity different from the first and/or an upholstery material (14) is provided. An intermediate layer (9) is arranged between the supporting body (7) and the flame-retardant layer (12) and/or the upholstery material (14). The intermediate layer is non-flamable, and composed of a lattice or mesh of high temperature resistant fiber or threads, and/or liquid repellent. The supporting body (7) can be foamed on to the intermediate layer (9). A process for manufacturing the seat (1) is also described.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
Fire-resistant seating, such as aircraft seats, which comprises at least a soft, supporting material and a cover, between which there is a fire-resistant intermediate layer, which is a combination of a layer of polyurethane foam which has been rendered fire-resistant, having a thickness between 1 mm to 15 mm, and a fiberglass fabric, characterized in that the fire-resistant intermediate layer is a combination of a layer of fiberglass fabric which is firmly attached to the soft supporting material, and a layer of polyurethane foam, which has been rendered fire-resistant and a firmly attached both to the layer of fiberglass fabric and to the cover.
Claim 2
Dependent Claim
