Definitions

  • the invention relates to a seat, in particular a vehicle seat, with a foam core and a cover material.
  • Mandhmal is backed with a layer of an open-pore soft foam that is just a few millimeters thick.
  • Such seat constructions have been known for many years, particularly for use in motor vehicles, and can be produced relatively easily and inexpensively.
  • a major disadvantage of such seat constructions is, however, that when a person sits down on them, the so-called "heat build-up" phenomenon often occurs. Humans usually release excess body heat through the evaporation of water, which normally already occurs in the skin. However, the water vapor produced must then be easy to remove in order to avoid heat build-up and not to impair the well-being of the person concerned. Otherwise the air layers close to the body become saturated, the excess body heat is accumulated and the sweat soaks the laundry while feeling uncomfortably moist heat.
  • the open-pore foam is compressed under load (when a person has taken a seat on a seat) in such a way that the open-pore and air-permeable material is compressed into a closed layer, which makes further water vapor transport very difficult or even completely impossible.
  • the foam lamination of the textile covering material is already sufficient for this phenomenon.
  • seats which enable significantly better water vapor transport.
  • These are the previously used spring seats, on which a mat, for example made of rubber hair, is arranged, which not only has a relatively good elasticity, but is also particularly permeable to air and thus water vapor.
  • a textile cover material In such seat arrangements covered with a textile cover material, the excess body heat in the form of water vapor can be easily removed through the cover material and the rubber hair layer as well as via the free spring core space.
  • the main disadvantage of such seats is their complex construction, which is too cost-intensive, especially for mass-produced items such as vehicle seats. For this reason, for example, almost all automobile manufacturers install the seats described at the beginning with a foam core and an outer material, which may be lined with foam, in their vehicles.
  • the invention has for its object to provide a seat of the type mentioned with a foam core and a coating material that allows both a removal of the body heat released easily, and is inexpensive to manufacture and can be used for mass articles.
  • a seat according to the invention is characterized by the features of the main claim.
  • “seat” is understood to mean any type of seat.
  • a seat construction according to the invention is particularly suitable for seats in which people have to sit for long periods of time and for seats which have a backrest, in which therefore there is a particularly large contact area with the human body and in which, in known seats, "heat accumulation" is particularly common were observed.
  • These primarily include car seats, seats for public transport, airplanes, but also seats for cinemas, theaters, congress halls or seats in private households.
  • “seat surface” is understood to mean the sides of a seat or a seat construction facing the user, that is to say in particular the sides facing the user of the mostly horizontal or slightly inclined base region of a seat, the back and side rests.
  • a seat according to the invention is subjected to a transport route after mechanical stress (in particular compression) by a person taking a seat, in particular for keep the water vapor released into the seat clear by not fully closing the grooves and / or channels even after mechanical stress on the seat.
  • the choice of the width and depth of the grooves or channels is made depending on the foam material used and the loads to be expected.
  • the foam core can consist of various open or closed-pore foam materials, such as polyvinyl chloride, polyurethane or polyethylene and similar foam materials, but it must have a more or less strong elasticity depending on the intended use.
  • closed-pore materials can also be used without any problems compared to the known seat arrangements, because not the foam core material, but in particular the grooves or channels, ensure that the water vapor released into the seat is transported away.
  • the seat namely the seat and / or the backrest
  • forced ventilation which forcibly controls the air circulation in the grooves or channels by blowing or sucking and thus ensures optimal removal of any moisture or air.
  • temperature-controlled air for the forced ventilation, which can be done in a simple manner, for example when using such a seat in automobiles or aircraft, by connecting to the ventilation or air conditioning system.
  • the known fault-prone heating wires in the seat can be dispensed with.
  • the grooves advantageously run in a straight line and continuously on the foam core surface. Depending on the area of application of the seat, the grooves only need over to run part of the foam core surface. However, the grooves advantageously extend over the entire surface, so that even if the user is in an off-center sitting position, the removal of any water vapor that is produced is ensured.
  • the foam core is surrounded on the sides approximately perpendicular to the seat surface by a frame which, in one embodiment of the seat according to the invention, has openings with grooves extending the grooves.
  • This frame advantageously extends beyond the surface of the foam core, so that a central recess is formed which is suitable for partially or completely receiving the air and water vapor permeable cover layer.
  • the frame not only serves to mechanically stabilize the seat in the edge area, but can also serve as a receiving frame for the air and water vapor permeable cover layer, so that the assembly of such a seat is particularly simple.
  • Rubber hair has proven to be particularly suitable as a covering layer which is arranged over the grooves.
  • Rubber hair is a composite material consisting of a natural or synthetic fiber and a binder based on latexes and which is used for various purposes, e.g. as packaging material, .. is used. Rubber hair has a high air permeability, which is easily maintained even under load. Rubber hair is also particularly suitable because a particularly elastic material is to be used as the covering layer, which increases the seating comfort. The excellent elastic behavior of the rubber hair also ensures good pressure distribution over the surface. Guin hair plates are preferably used, which are inserted as such over the entire surface of the foam core or into the recess formed by an optionally arranged frame.
  • the covering material placed around the foam core and the covering layer must be permeable to air. While woolen fabrics are particularly comfortable, they are only used for the seats of expensive cars, buses or airplanes for cost reasons. For standard seats, the abrasion resistance of the outer fabric is more important.
  • a conventional air-permeable covering material for example woolen fabric, is underlaid with a very air-permeable fleece, preferably a few millimeters thick.
  • a fleece is a moisture-storing and moisture-permeable one Material such as rayon or dunova, which have a coarser structure that is sufficient to remove body moisture.
  • hydrophilic binders can be mixed with the nonwoven material for reinforcement.
  • a seat according to the invention is designed in such a way that the multilayer structure has a water vapor permeability of at least 10ooo g / m 2 . Has 24 h, so that "heat build-up" can be reliably prevented.
  • FIG. 1 shows: Perspectively a car seat according to the invention in which the basic area is partially cut open.
  • Figure 2 schematically shows a section through an inventive seat element.
  • the foam core 4 with the grooves 9 and the frame 6 'with the openings 1o has been produced as a molded part in one operation, which makes production very simple and inexpensive.
  • the design of a frame 6 has several advantages. On the one hand, this mechanically reinforces the entire construction. On the other hand, it is avoided that the grooves 9 run out freely at the ends, as a result of which the lower stability of such grooves in the end region prevents the risk of closure, if a person loads the seat off-center. Furthermore, the insertion of, for example, a rubber hair mat or plate 11 into the recess 12 formed by the frame 6 is facilitated by the raised frame 6.
  • the air and water vapor permeable layer or plate only needs to be inserted into the depression 12, which is particularly simple.
  • the foam core 4 and the rubber hair plate 11 inserted into the depression 12 are surrounded on all sides by a woolen fabric 14 which is underlaid with a fleece 13 of cellulose and glued in a punctiform manner, the fleece 13 being mixed with a hydrophilic binder.
  • the backrest 3 is constructed in the same way as the base region 2, the grooves 9 or the openings 10 in the exemplary embodiment shown in the drawing running from left to right, that is to say parallel to the grooves 9 of the base region 2, as a result of which the removal paths for any Water vapor released into the seat is particularly short.
  • the vehicle seat shown in FIG 1 has a water vapor permeability of more than l o.ooo g / m 2 24 h, whereby heat accumulation can be reliably prevented by discharged into the seat steam.
  • the latter can also have channels which are guided through the foam core and, like the grooves, for the removal of moisture or water vapor . serve.
  • the seat in the case of particularly high-quality seat constructions (for pilots, for example), can be provided with forced ventilation, which forcibly controls the air circulation in the grooves (9) or channels by blowing or sucking and thus ensures optimal removal of any moisture or air .
  • the forced ventilation can also be directly connected to the ventilation or air conditioning system, which additionally results in the possibility of a temperature-controlled seat.
