  • Patent number: 6042764
    Abstract: A method of producing a three-dimensional shaped plastic foam part comprises the steps of mixing plastic foam granules of a predetermined range of sizes and of different hardness in a predetermined mixing ratio to obtain a mixture of the plastic foam granules, mixing the mixture of the plastic foam granules with a liquid primary material until the granules are coated with the liquid primary material and a mixture of coated plastic foam granules is obtained, feeding a preset quantity of the mixture of coated plastic foam granules into a mold cavity of a mold closed on all sides, reducing the volume of the mold cavity at least in partial regions thereof after it has been filled with the mixture of coated plastic foam granules, triggering a reaction of the liquid primary material by applying pressure and heat until a continuous cellular structure of plastic foam has been formed and the plastic foam granules have been interconnected by the cellular structure of plastic foam after the volume of the mold cavity has

  • Patent number: 5885693
    Abstract: A three-dimensional shaped part comprises at least one first portion having an equal density throughout the volume thereof and comprising a plastic foam of a primary material having a cellular structure and plastic foam granules interconnected by the cellular structure of the plastic foam, and at least one second portion having an equal density throughout the volume thereof, the second portion being adjacent the first portion and comprising a plastic foam of a primary material having a cellular structure and elastically precompressed plastic foam granules interconnected by the cellular structure of the plastic foam. 70% to 90% of the volume of the shaped part is formed by the plastic foam granules, and the density of the second portion is greater than the density of the first portion.

  • Patent number: 5518806
    Abstract: The invention describes a foamed material panel, in particular a shaped part composed of one or several foamed material panels. These panels consist of a soft and, if appropriate, elastic foamed material comprising cellular webs and/or cellular walls that are permanently deformed at least in some areas. A central area of the foamed material panel is plastically deformed to a higher volumetric weight than at least one intermediate area of the formed material panel.

  • Patent number: 5248185
    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.

  • Patent number: 5055339
    Abstract: A shaped element consists of a soft and preferably elastic foamed material, comprising cellular webs which have been deformed remanently at least over areas. The shaped element is formed from a foamed material granulate, a soft foamed material having a grain size of 2 to 20 mms and filler material, for example cork granulate, rubber granulate, chalk, calcium carbonate, hard polyurethane scraps or thermoplastic plastics material scraps, with a grain size of 2 to 20 mms, which are distributed in the soft foamed material by the foaming action. The cellular webs or walls between the individual floccules of the foamed material granulate and/or of the filler material are remanently deformed over the areas concerned.
