Abstract
Automobile seats having improved comfort have a spacer layer included within the layers of cushioning materials. The spacer layer has a large void volume and nearly unrestricted flow of air. Heated, cooled or ambient air can be forced into the spacer layer of the seat, making the seat more comfortable with respect to temperature and removal of perspiration.
Claims23
A vehicle seat comprising (a) two or more layers of materials selected from cushioning materials and fabrics, and (b) a spacer layer between said layers of materials and positioned within about one inch of the outer surface of said seat, wherein said spacer layer comprises one or more layers of a three-dimensional fiber network comprising a knit or woven textile fabric having a multiplicity of projections comprised of said textile fabric rising from the plane of said textile fabric, said textile fabric comprising thermoplastic filaments having a diameter of at least about 0.1 mm, wherein said spacer layer has a density less than about 10% of the density of the materials used to make said spacer layer.
A vehicle seat comprising a knit or woven textile fabric having a multiplicity of projections comprised of said textile fabric rising from the plane of said textile fabric, said textile fabric comprising thermoplastic filaments having a diameter of at least about 0.1 mm.
A method of making a vehicle seat, comprising the steps of (a) providing a three-dimensional fiber network comprising a knit or woven textile fabric having a multiplicity of projections comprised of said textile fabric rising from the plane of said textile fabric, said textile fabric comprising thermoplastic filaments having a diameter of at least about 0.1 mm, and (b) incorporating said three-dimensional fiber network as a layer in said vehicle seat.
