Abstract
The invention concerns a vehicle seat, in particular for aircraft, comprising: a cushion made of plastic foam, a supporting body of an open-cell, resilient plastic foam with a first relative density; a middle layer with a second relative density different from the first; and a covering material. The layers are bonded together. A flame-resistant intermediate layer may be arranged between the supporting body and the covering material. The intermediate layer may be formed from a lattice or mesh of high temperature-resistant fibers or threads. The middle layer (18) is a nonwoven fabric of at least one fiber layer of needled or thermally bonded fibers or threads of synthetic and/or natural materials which are preferably applied to a carrier layer by needling.
