Definitions
- the invention is directed to a cushion made of plastic for seating furniture and vehicle seats, the load area of which has elevations of different geometries, between which there are free spaces, the elevations forming a piece with a support plate made of the same material that is common to them.
- Upholstery cushions of this type are used primarily in the furniture sector, as they are e.g. are known from FR-A-2131448.
- Another known possibility is the working out of separate recesses, whereby a reduction in the hardness in partial areas of cushion elements has been achieved by reducing the load-bearing foam volume.
- the seat cushion of which is made of a relatively thin support plate with elastic elevations, which are optionally arranged on both sides; consists. Rubber, plastic or another elastomer is provided as the material for the seat cushion.
- the ridges have the shape of small and large mushrooms. They can be evenly or unevenly distributed.
- the mushrooms form the load-bearing, comfort-giving elements, while the support plate essentially serves only as a support for you mushrooms.
- Such a construction can only be made from non-foamed material, because when using foamed material, the relatively sensitive stems of the mushrooms would quickly tear off due to the inevitable transverse stresses.
- this seat cushion is unsuitable for automobile seats because it would give the seat a feeling of being too hard given the high dynamic loads during the journey.
- the request for protection is directed to a work chair with a seat and backrest, the seat and backrest each being formed in one piece from elastically resilient plastic foam and anatomically adapted and at least partially provided with flat knobs on their seat surface or rest surface .
- Smaller knobs, more densely than in the central area of the seat, are preferably provided in the other area of the seat, where the thighs of the seated person rest. Use of this cushion for vehicle seats is not taught in the document.
- the task is to find an upholstered cushion for seating furniture, but especially for vehicle seats, which ensures high seating comfort thanks to an optimal indentation characteristic that is tailored to the body and the stress, while the elevations of the cushion cushion can also withstand heavy transverse loads.
- the solution to the problem is that the material is foam-molded; that the support plate represents the actual cushion; that the height of the elevations is small in relation to the height of this cushion and that the distribution of the elevations of different geometries corresponds to the different loading zones of the cushion.
- elevations can be foamed at the same time as the actual cushion cushion during the molded foaming process and that, for example, elevations of a different geometry can be provided in the area of the buttocks than in the area of the less stressful thighs.
- the elevations can have a wide variety of designs, such as truncated cylinders, cones, truncated cones, pyramids, truncated pyramids, spherical caps, cuboids, prisms, ribs. Size and height are also of particular influence.
- a reaction system which, for example, forms polyurethane foam with high indentation hardness is used to produce the foam-molded cushion.
- the areas of the cushion that can be set softer are obtained by dimensioning the elevations accordingly. In this way, upholstery cushions with increasingly different hardness can be produced, in which the transition from one degree of hardness to the other can be adjusted almost continuously.
- the cushion 1 has side reinforcements 2, between which the actual seat 3 extends.
- This seat 3 is covered with three groups 4, 5, 6 of frustoconical elevations 7 of different sizes and heights.
- the geometry of these elevations 7 is matched according to the individual groups 4, 5, 6 to the stress to be recorded in each case.
- the height of the elevations 7 is small in relation to the height of the actual cushion cushion 1.
