Definitions

  • the invention relates to a support for the seat or backrest surface of a seat or the reclining or seating surface of a reclining or seating furniture to prevent or dissipate condensing moisture, in which passages are provided between the person and the contact surface of the support, which provide access to Improve air.
  • the object of the invention is to improve a support of the type mentioned at the outset in such a way that the accessibility of the air to the passages is further improved and good drying is brought about.
  • the invention proposes that the contact surface is part of an exchange layer, in which air outlet openings are arranged, and that a substructure is provided below the exchange layer, which carries an air inlet for feeding in air and with a distributor structure for distributing the fed-in air to the individual air outlet openings.
  • the edition according to the invention is e.g. B. applied to a car seat or an office chair in the manner of a slipcover, so z. B. attached to the backrest by a bag-like design by slipping or fixed with straps reaching around the seat or the backrest. It is therefore suitable as a retrofit part for vehicles and office furniture as well as for hospitals and old people's homes.
  • the air fed into the air inlet can be the room air, a heated room air or a conditioned or left fresh air, which depends on the local conditions. In any case, a high air exchange is brought about on the contact surface between the person and the seating or reclining furniture, which ensures good moisture removal in condensed or vapor form.
  • the individual air outlet openings can be arranged within grooves so that they are not completely closed by contact with the person.
  • the entire exchange layer can consist of an open-pore foam, which creates the air outlet openings due to its open-pore structure.
  • separate air outlet openings can also be provided at certain points.
  • the top layer of the overlay can be formed by a decorative fabric overlay, so that a pleasing appearance and adaptation to existing fabrics is possible.
  • the edition can also be in one Be covered with fabric that surrounds the entire edition. The cover is closed with a zipper. Only an opening for connecting the air supply is provided on the cover. The cloth clothing of the seated person, the air-permeable cover and a ribbed surface of the pad guarantee perfect air circulation.
  • the support can be connected to the outlet opening of such a system via a hose and an adapter.
  • the interior air of the motor vehicle can also be blown into the interior of the support in a simple manner with the aid of a compressed air generator.
  • the compressed air is preheated using a heating element.
  • the air can also be taken from the environment, for example removed from an installed fresh air nozzle or, for example, with a suitably long hose at a suitable point. B. in the engine compartment.
  • the support 1 shown in FIG. 1 essentially consists of a substructure 2 and an exchange layer 3.
  • the substructure 2 consists of an elastic plastic with an integrated distributor structure, that is to say with channels and spaces lined up in order to uniformly blow air blown in via a pipe socket 6 over the entire length Distribute area and let it come out of air outlet openings 5.
  • the distribution structure is not shown. However, the average specialist referred to is easily able to implement a corresponding distribution structure that is based on findings from the air conditioning of rooms.
  • the support 1 shown is attached to the seat of a motor vehicle seat with the aid of tapes. To do this Loops 10 are provided on the side, to which the optionally elastic bands are attached.
  • a compressed air generator 8 is connected to the pipe socket 6 with the aid of a hose 12, which sucks in the vehicle air via a filter 13 and, if necessary, heats it.
  • the compressed air generator is, for. B. attached under the car seat or on the side or on the backrest, if necessary with the help of a Velcro fastening.
  • the compressed air generator 8 carries two rotary switches with which the rotational speed of a fan located therein on the one hand and the intensity of an electric heater on the other hand can be set.
  • a remote control 16 can also be provided, on which this operation is then possible and which, for. B. is attached at a suitable location on the dashboard.
  • a corresponding hose 12 can in turn be connected via a filter element 13 to an adapter 14 which, for. B. is connected to the existing air conditioning or ventilation and heating system in the motor vehicle.
  • the adapter 14 is in the form of a funnel, it can also be arranged at a location under the bonnet or in the front part of the vehicle at which a dynamic pressure is created by the wind. There is then no need for a blower or just a blower for a drive in the stationary state.
  • the adapter 14 is connected to the existing air conditioning, ventilation or heating system of the vehicle, it may be expedient to provide a separate quantity regulator, that is to say in the edition 1 to be able to regulate the given air volume separately.
  • a separate quantity regulator that is to say in the edition 1 to be able to regulate the given air volume separately.
  • Such a controller is preferably implemented with the aid of a slide, the details of which are not shown in the figure.
  • the exchange layer 3 is not separable from the substructure, but both plastic parts are, for. B. firmly glued together. In individual cases, however, B. for hygiene reasons, the exchange layer 3 can be removed from the substructure 2, which can easily be made possible.
  • a power supply for the compressed air generator 8 on the basis of 220 V alternating current is recommended for domestic use. If exclusive operation is provided in a motor vehicle, 12 V or 24 V can be selected as the operating voltage. For camping or similar outdoor use, e.g. B. for the equipment of seats for spectators at tennis tournaments or the like can also provide a rechargeable battery or the like for the power supply. If necessary, a current converter can be provided, which is used for low-voltage direct voltage, but is unnecessary for 220 V alternating current.
  • Figures 2 and 3 show a support 20 in the form of a hollow body with an upper part 21 and a lower part 22.
  • the support 20 is made of an elastically resilient Made of plastic that has a certain inherent rigidity.
  • the upper part 21 essentially consists of an upper wall 23, the side walls 24 and 25, an end wall 26, two continuous webs 27 and 28 and side webs 29 branching diagonally therefrom.
  • the webs 27 and 28 run parallel to the side walls 24 and 25 in such a way that channels 30 of approximately the same width are formed.
  • the side webs 29 cover about 2/3 of the channel width, so that passages for the air remain.
  • the support 20 has an opening 31 which lies opposite the end wall 26 and extends over the entire width of the support 20. The opening 31 serves to supply air.
  • the air is pressed into the opening 31 and sweeps along the side walls 24 and 25 and the webs 27, 28 and 29 to the front area of the support 20.
