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.
Claims44
In combination with a vehicle seat, a seat cushion comprising
- (a) a supporting body of an open-cell, resilient plastic foam, the plastic foam having a first relative density,
- (b) a covering material, and
- (c) a middle layer arranged between the supporting body and the covering material, the middle layer being connected to the supporting body and being comprised of a nonwoven fibrous web of at least one layer of firmly interconnected fibers or threads, the nonwoven fibrous web having a second relative density differing from the first relative density;
- (d) said fibers or threads needled together;
- wherein at least some of the fibers or threads are comprised of synthetic materials;
- and
- wherein the synthetic materials comprise thermoplastic resins, and the fibers or threads are at least partially thermally bonded to each other.
In the combination of 1, wherein the covering material is laminated to the middle layer, a polyether or polyester foam layer bonding the covering material to the middle layer.
In a combination with a vehicle seat, a seat cushion comprising
- (a) a supporting body of an open cell, resilient plastic foam, the plastic foam having a first relative density,
- (b) a covering material, and
- (c) a middle layer arranged between the supporting body and the covering material, the middle layer being connected to the supporting body and being comprised of a nonwoven fibrous web of at least one layer of firmly interconnected fibers or threads, the nonwoven fibrous web having a second relative density differing from the first relative density,
- wherein the nonwoven fibrous web comprises mainly fibers or threads of a synthetic material and the synthetic material of at least a portion of the fibers or threads has a softening point between 100.degree. C. and 150.degree. C.,
- (d) said fibers or threads needled together,
- (e) the middle layer is connected to the supporting body over the whole surface of the middle layer.
In a combination with a vehicle seat, a seat cushion comprising
- (a) a supporting body of an open cell, resilient plastic foam, the plastic foam having a first relative density,
- (b) a covering material, and
- (c) a middle layer arranged between the supporting body and the covering material, the middle layer being connected to the supporting body and being comprised of a nonwoven fibrous web of at least one layer of firmly interconnected fibers or threads, the nonwoven fibrous web having a second relative density differing from the first relative density,
- wherein the nonwoven fibrous web comprises mainly fibers or threads of a synthetic material and the synthetic material of at least a portion of the fibers or threads has a softening point between 100.degree. C. and 150.degree. C.,
- (d) said fibers or threads needled together,
- (e) the middle layer is connected to the supporting body only at certain points on the supporting body.
