Definitions
- the invention relates to a seat, backrest or couch upholstery and generally aims to improve the ventilation of such upholstery.
- a problem with the ventilation of the seat and lying surface is that conventional seat upholstery is compressed under the weight of the person sitting or lying down, whereby the thermal insulation is reduced, but the ventilation is generally severely impaired. Strong thermal insulation or even active cooling with little ventilation of diffusion-permeable seat coverings can lead to condensation in the colder area of the upholstery, often combined with fungal growth of these areas which is not hygienically safe and which is in no way hermetically sealed.
- seat upholstery has been proposed (WO 95/14 409, WO 96/05475) in which air-conditioned air is blown out under pressure through channels and through pores of the upholstery to the buttocks and back of the seated person by means of a blower.
- a blower In the case of these known seat upholsteries, in spite of the very high outlay, an inadequate assignment of the ducts supplying and discharging the drainage air to the seated or leaning person can only be expected to have a slight effect or a large amount of energy. In particular, uncomfortable hypothermia can be expected in the peripheral zones of a seated person due to the intensive bypass flow.
- Mat-like pads are also known (US Pat. No. 5,004,294; EP 0 689 786 A1) which contain a large number of valves which are actuated by the load of a seated person. Then conditioned air is blown out through the valves against the seat and back area of the seated person. With these seat covers, the valve lift is small in comparison to the compression of the upholstery, so that the seat covers practically do not contribute to the upholstery effect. The blown-out conditioned air can lead to undesirable hypothermia in the areas of the body mentioned. The problem of air removal of this air, which is enriched with body vapors, is not considered.
- the invention has for its object to provide a device for effective and pleasant ventilation of seating, backrest or lying surfaces, which a draft-free ventilation essentially on the areas of the sitting or lying surfaces touched by the body with little manufacture - and operating costs limited.
- the device is also intended for retrofitting existing seating and lying furniture.
- the drainage air flow is automatically increased by the surface pressure on the part of the seated person or a desired flow distribution is effected. This is done by opening the valve means, which are preferably connected in parallel, and which only release the passage cross section under pressure or pressure.
- the drainage air is not passed the contaminated surface, but actually penetrates where the ventilation should be effective.
- the flow cross-sections of the valve means and the drainage channels can be designed such that a very small pressure difference of the order of 50 to 200 Pa and a correspondingly low energy expenditure is sufficient for a sufficient air throughput.
- Retrofittable upholstery according to the invention can consist of a gas-permeable, thin cover layer with a high heat transfer coefficient as a contact surface with the seated person and a sufficiently thick drainage layer underneath with a low flow resistance, for. B. in the form of an open-cell foam or a coarse fiber layer. This drainage layer can be closed off on the side facing away from the seated person with a largely diffusion-tight film.
- the drainage layer can be connected to a low-noise blower operated by pressure or suction, the speed of which or the volume flow through it can be adjusted manually or can be regulated automatically by means of a temperature sensor and / or moisture sensor and a setpoint element can be.
- the adaptation of the drainage air throughput to the physical conditions (dimensions, weight) of the seated person can be effected with the aid of a rotary slide valve which is installed in a cylindrical collector.
- the seat air conditioning can be connected to a hose via a hose.
- the valve means can, as known from US-A-5 004 294, a variety of valves, e.g. B. have poppet valves. These valves are opened by the weight of the seated or lying person against resilient spring elements which, according to the invention, significantly affect the upholstery affect the upholstery. Thus, when the air-conditioned seat or the lying surface is in pressure operation, the drainage air is pressed through the breathable cover layer over a small area and is correspondingly drawn off in suction operation. On the side of the valve sealing surfaces facing away from the seated or lying person, a duct system is arranged, via which the drainage air can be supplied or discharged.
- a duct system is arranged, via which the drainage air can be supplied or discharged.
- Such checkerboard-like valve systems represent a particularly energy-saving solution, since the cross-section of the drainage channels is only released for the drainage air in the area occupied by a person sitting or lying down, while in a system with channels connected in parallel by actuating one Valve in the seat or lying surface of one of the channels over the entire length of the channel, e.g. B. also on the breathable upholstery of the backrest, the drainage air is promoted without the seated person having to lean.
- the problem with seating surfaces differs from that with lying surfaces in that the assignment of seated people and seating, in any case z. B. in desk chairs or car seats, is geometrically relatively precise, while a person lying on a mattress can occupy a wide variety of positions. Accordingly, in the case of mattresses, an embodiment is advantageous which is made up of a large number of valve-like elements which are arranged over a large area and react to loading by opening. In the case of desk armchairs and individual car seats, the construction should also be such that the extracted or blown-out drainage air is not uselessly bypassed by the person sitting in the bypass, but is directed through those areas which are intensely warm and humid ⁇ need to be removed.
- the drainage air distribution is adapted to people of different widths by placing an upper template on the seat, backrest or lying surface, which is provided with drainage openings in an arrangement adapted to the personal body dimensions.
- foam elements of the upholstery themselves serve as valves and form a multigonal mosaic over a large area, preferably in the form of a hexagonal grid.
- foam elements can have air-impermeable intermediate layers which, when the element is subjected to pressure, contracts it transversely and thereby releases voids for the passage of air, so that the drainage air ducts via the open-pored sections of the foam elements and via said voids with the drainage ducts of the padding or Cavities in a seat shell and are fluidly connected to the pressure or suction operation collector.

- FIG. 11 shows a longitudinal section through a mattress upholstery designed according to the invention
- FIG. 13 is a partial section on an enlarged scale of an inflated air mattress according to FIG. 12.
- FIG. 1 shows a desk armchair which, according to the invention, is equipped with a ventilation system.
- the contact surfaces 3 and 4 with the seated person are covered with a breathable fabric layer 1, which has a sufficiently high flow resistance against the suction of air.
- a breathable fabric layer 1 Under this layer of fabric 1 is an upper cushion 2 built of porous material, which has a higher rigidity, so that it is not compressed too much under the weight of the person sitting.
- the flow resistance of this upper cushion, the z. B. with longitudinal ribs in the direction of the spine of the seated person is reduced according to the invention by the weight of the seated person.
- the open-pore upper cushion 2 contains drainage channels 15 which, according to FIG. 1, are connected to a collector 5 accommodated in the neck cushion 6.
- a drainage air line 7 leads to the suction side of the blower 8, the motor of which is connected to an accumulator 9, which can be recharged via an electrical connection 10.
- Blower 8 with motor and accumulator are housed here in a soundproof room in the flow of the chair.
- the drainage air line 7 can be routed outside the backrest and seat to the blower. Then there is an arrangement, not shown here, of blower and accumulator in a flat design, which can be attached to the backrest.
- FIG. 2 shows a valve 18 with valve flaps 19 which is customary in inflatable floating wings and which is built into each of the parallel drainage channels 15 of the upper cushion 2 (FIG. 1) and is closed when the seat is unloaded (FIG. 2c)). Under the pressure load from a seated person, the valve 18 opens automatically the more (FIG. 2b)), the higher the local pressure load is. This is intended according to the invention because the removal of heat and water vapor should be most intensive at places with high pressure loads.
- FIG. 3 shows a drainage air collector 5 built into the neck cushion 6 of the armchair according to FIG. 1 with an internal Gending rotary valve 13, the passage window 17 is designed with a contour 14 so that a drainage air distribution adapted to body weight and mass on the drainage channels 15 connected in parallel is achieved by appropriate angular adjustment of the rotary valve 13.
- valve 4 shows a section of an upholstery according to the invention with contact surface 3 or 4 for the person sitting or leaning against it, which is covered with a breathable fabric layer 1 and is upholstered with an open-pore upper cushion 2.
- a layer of a plurality of valve closers in the form of valve disks 20 is arranged under the upper cushion 2 and separated therefrom, which, when loaded by a person sitting or leaning against it, opens its contact pressure profile against return springs in the form of spiral springs 21 and thus release a flow cross-section 22 for the drainage air which is supplied or discharged via drainage channels 41 in the hollow sub-floor.
- the valve seats can be formed by circular holes 23 in an intermediate floor 24 which is supported against the seat shell or a floor 42 via spacer elements 40.
- the coil springs 21 have a stroke, the size of which largely determines the cushioning effect.
- Fig. 5 shows a section of another embodiment of the invention with a contact surface 3 or 4 to the person sitting or leaning, in which the valves are realized by appropriately structured foam elements of the upholstery.
- An unloaded section is shown on the left and a loaded section on the right.
- the foam elements 36 which are preferably hexagonal and are open-pored with the usual upper cushion 37 and can thus be assembled into a regular grid, are constructed as follows.
- Conical punch 25 made of open-pore foam which is enclosed by a somewhat softer ring 35 made of open-pore foam, is pressed into one by the pressure exerted by the seated person against a largely air-impermeable, flexible, but in the longitudinal direction hard expansion layer open-pore stamp pad 28 filled with soft foam 27 and thereby pulls the edge 29 of the element towards the axis 30.
- An annular cavity 31 is thus created around each of the loaded elements. Through this cavity 31, the open-pore stamps become
- stamp pad areas 27, 28 are fluidly connected to one another and to the drainage channels 41 in the seat shell or lower cushion 33, 34, which discharge the drainage air 32.
- FIG. 6 shows another variant.
- a transverse contraction of the hexagonal elements 36 is brought about by a cylindrical bulge surface 38, which surrounds an open-pore, cross-compression-soft core 39.
- the stiffness of the bulge surface 38 is such that the bulge surface bulges toward the axes 30 when the elements 36 are subjected to pressure, so that an annular cavity 31 is formed, over which the open-pored areas on the sealing intermediate layer
- the foam valves form the main cushion which effects the cushioning effect.
- the upper cushion 2 is manufactured.
- open-pore foam with low transverse contraction rigidity is molded into a shape corresponding to the punches 25 or cores 39. splashes.
- the annular intermediate layer 26 of somewhat harder open-pore foam is then injected into the interspaces.
- the underside of the upper part shaped in this way is laminated with an air-impermeable, compression-resistant layer.
- the intermediate layer 26 is cut open along the central surface with a honeycomb-like punching tool. This upper part is then glued onto a correspondingly congruent lower part, adhesive being applied only in the central region of the cores.
- hexagonal elements are prefabricated, which are then configured in a mosaic-like manner to form a flat structure.
- the hexagonal elements according to FIGS. 5 and 6 are glued open-pore with large-area air-permeable cover and base layers.
- Fig. 7 shows a further embodiment of an upholstery according to the invention.
- the air flow is shown by arrows.
- the seat or the seat cover 45 is equipped with a draining air-permeable base template 46, which is designed for broadly built people. Slightly built people place an appropriately small-area upper template 47 provided with drainage openings 48, which is equipped with a coarse-pored upper padding 49 for the transverse transport of drainage air under the seated person.
- the backrest can be constructed accordingly.
- a coarse-porous base layer 51 is provided along the drawer-like air-impermeable seat or backrest shell 50 for the transport of the drainage air 52.
- Spiral springs lying parallel or twisted in one another run towards the drainage air collector (s) 53 and thus represent a fluidic, low-pressure connection.
- Sitting comfort lies on this “coarse porous” base layer 51 Increasing soft, open-pore under-cushioning 54 or under-cushioning with drainage air openings which run essentially perpendicular to the seat surface or backrest.
- the base template 46 described above lies on this underpads as the cover layer of the lower cushion 55.
- the upper cushion 56 is placed on the lower cushion, the lower surface of which forms the personal upper template 47.
- This top template is provided with a hole or slot pattern 57 for the passage of air, which is shown on the left-hand side of the top view, and which facilitates the optimal removal of heat and moisture, e.g. B. along the spine to the coccyx and in the crotch area, but also on the highly stressed "sit bones".
- This upholstery can also have a rib-like or spiral structure, which particularly favors the entry of air from the unloaded sides. A mesh-like, good heat-conducting fabric is recommended as the cover fabric.
- FIG. 8 For lying surfaces, in particular for pocket spring mattresses, the embodiment of the invention shown in FIG. 8 offers advantages which, however, are also possible for a sophisticated seat structure.
- the coil spring of each pocket 60 is a one-piece "reversing spring" 61 with z. B. conical core 62 which is surrounded by a cylindrical spring portion 63.
- the cylindrical spring section is supported on the upper floor 64 of the hollow lower floor 65, during the somewhat shorter, conical inner spring section in the unloaded state of the mattress pulls a valve disk 66 into the valve seat 67.
- the valve disk is pressed against an elastic body 68, the rigidity of which, in conjunction with that of the reversing spring, determines the opening and closing characteristics of the valve.
- a largely local sink flow at the stressed point can only be achieved with this configuration, however, if the side walls of the pockets 60 or of pocket groups have a comparatively high flow resistance.
- the hollow underbody 65 consisting of a closed outer cover 69 and the upper bottom 64 containing the valve seats 67, can be flexible, e.g. B. be made of a sufficiently rigid natural rubber, so that even with this mattress an adjustment of the grate is easily possible.
- FIGS. 9 and 10 show two versions of upholstery according to the invention which are favorable in terms of manufacture and assembly.
- the upholstery of a seat or reclining surface here consists of an underpadding 81, which is produced from a somewhat stiffer closed-cell foam. and an upholstery 80.
- the upholstery 80 has a strip-like valve closer 82 made of closed-cell foam in the form of a rib-shaped thickening on a web 83 which is connected to a softer compensation layer 85 and / or through which drainage holes 84 pass.
- the underpadding 81 contains cylindrical cavities 86 running along its length, which serve as drainage channels. The cavities are open at the top via elongated slots or narrow points.
- Line-shaped valve seats 87 are formed on both sides of these constrictions.
- the webs 83 with the valve closers 82 protrude into the cavities 86 through the constrictions.
- the padding 81 is laminated on the underside with a largely air-permeable cover layer 88, which is flexible in mattresses.
- the rib-shaped valve closers 82 are pressed into the cylindrical cavities 86 of the under-cushioning and thus lift off from the valve seats 87. This creates a fluidic connection from the environment beneath a person 70 who is sitting or lying on the upholstery and the loaded padding section to the cavities 86, which can be connected to a blower operated by suction or pressure.
- the compressible valve closers 82 of the upper upholstery are squeezed from above through the valve seats 87 of the lower upholstery or are pushed in laterally, the valve closers 82 sealingly resting against the valve seats 87 with little pretension in the unloaded case.
- the valves are also integrated into the upholstery here.
- the lower cushion is formed by strip-shaped elements 89, which form the linear valve seats 87 and the cavities 86.
- said strip-shaped elements are rigid and can be produced in one piece with the seat shell or connected to it.
- the entire spring and valve closing path is included in the upper cushion 80.
- the valve closers 82 are designed to be sufficiently compressible if they are to be able to be pressed into the larger drainage cavity 86 in the underbody during initial assembly through the valve seats 87.
- This configuration can easily be dismantled for cleaning or recycling, since gluing of the upholstery and seat shell is unnecessary.
- valve closers 82 in FIGS. 9 and 10 are to be understood as rotationally symmetrical (spherical) bodies and the constrictions with the valve seats 87 as conical bores. In this case, assembly is only possible by squeezing through, but not by pushing the top padding into the bottom padding from the side.
- valve layer consisting of the elements 82, 87 could be very thin, e.g. B. with a thickness of only 10 mm up to the thickness of a strong upholstery fabric.
- a valve layer cushion could be placed as a thin seat cushion on a padding which is now very simple to carry out and which is connected flatly to a drainage air supply.
- the side of the valve layer cushion facing this person could e.g. B. have a rib structure, which forms a groove-shaped upper drainage, which could be covered by an open-pore, but firm, ie not stretch-like covering material. This acts as a dust filter to prevent rapid internal contamination of the valve layer, and as a barrier against flow blockage of the upper drainage z. B. in that the fibers of a woolen fabric press into these gaps under the pressure of the seated person.
- the air for air conditioning in the upper drainage layer 37 (FIGS. 4 to 6) or 49 (FIGS. 9 and 10) can be discharged laterally, since this drainage layer has a very high level good transverse permeability is designed as a tangential drainage layer. 4, 5 and 6, an upholstery is shown, in which air permeability of a contacting object was assumed, such as that e.g. given the controlled cooling of porous products, while the air permeability of the load object is excluded in FIGS. 7 to 10.
- a difficulty with the upholstery according to the invention is that no air is passed through in the unloaded case, as is the case, for. B. for cooling a vehicle seat would be desirable before the passenger sits down.
- the invention provides for the extraction fan to be equipped with an overload stage, so that when this stage is switched on, a significantly increased suction vacuum is created in the cavities, due to which the valves open even without stress from a seated person.
- the air inlet duct can be via a
- adjustable throttle valve can be connected to the ambient atmosphere. If this throttle valve 114 were completely opened, the drainage air flow would largely decrease through the lying surface 115 occupied by the person because the negative pressure in the drainage channels 112 would be greatly reduced by opening the throttle valve. This enables simple adaptation to the seasonal conditions. Furthermore, the moisture fed into the mattress during the sleeping period can be expelled from the region lying downstream of the valve layer 117 by switching on the fan in the collector 116 and opening the throttle valve 114.
- mattresses should be set up for ventilation from time to time. This is particularly difficult for older people and is unnecessary due to the configuration described according to FIG. 11.
- a moisture sensor at 119
- a temperature sensor at 120
- switch-off times or control values for the fan power can be specified automatically.
- a timer can be provided which limits the operating time of the fan to two hours.
- the suction air flow can be controlled depending on the humidity and the temperature in an adaptable manner to the needs of the person sitting or lying down.
- FIGS. 12 and 13 represents a further development of the construction according to FIGS. 9 and 10 into an inflatable air mattress.
- the under-cushioning 81 provided in FIGS. 9 and 10 is replaced here by inflatable hollow chambers 90, which are produced by gluing the airtight base 88 to the airtight protuberances 91 forming the valve seats 87.
- the upholstery 80 is replaced by a system of inflatable hollow chambers 92, which are produced by gluing a lower layer 93 forming the valve closers 82 to an upper layer 94.
- the top padding is provided with openings 95 in the area of the adhesive bond. Via these openings, drainage air can flow into the cavities 86 from the upholstery when the mattress is loaded.
- the top layer 94 which is wavy after inflation, is covered with a porous cushion layer 1.
- drainage air passes under the lying person 70 to the flow sinks which are formed in accordance with the load profile of the person by pushing the valve closers 82 away from the valve seats 87.
- the Draina air is supplied to a small fan 101 via the cavities 86, which are combined via a collector 100 (FIG. 12).
- a sufficient ventilation in many cases can also be achieved here without connection to a suction or pressing fan by thermal effects.
- the air mattress according to FIGS. 12 and 13 can be folded to a small volume and offers in particular Extraction operation even when traveling in hygienically ongoing areas on hotel beds Protection against infections and parasites, without this having to be bought through an airtightness which is otherwise typical for air mattresses and the resulting excessive sweating.
- Figures 4 to 6 and 8 to 13 show largely to scale sections through upholstery into which, according to the invention, valve means are integrated, which, measured by the layer thickness of the upholstery, elastically cushion a large distance of 20-80% of the total upholstery thickness can.
- valve means are integrated, which, measured by the layer thickness of the upholstery, elastically cushion a large distance of 20-80% of the total upholstery thickness can.
- the desired low differential pressure in the order of 100 Pa, which the connected blower delivers, only low flow velocities may occur in the drainage channels; since the dynamic pressure of the flow is already approximately 60 Pa at a flow velocity of 10 ms "1. Since the flow does not run in a straight line, but several deflections and large changes in cross-section occur, as for example from FIGS. 9 and 10 If the tangential drainage channels 37 (FIGS. 4 to 6) or 49 (FIG.
- the valve means are dimensioned such that the valve closers 20 can cover a stroke 1 which is at most about 50% of the thickness of the upholstery. Even at the end of this stroke path, the valve still has a residual opening cross-section sufficient for ventilation, because the plate-shaped cover 20a which improves the seating comfort has a smaller diameter dp at the end of the valve axis 20b than the valve seat ds.
- the dimensioning of the valves made of upholstered foam is also largely to scale. While the upper drainage layer 37 and the lower drainage channels or layers 33, 34 are primarily flexible but hardly compressible, the padding is valve layer 36.39 designed both flexible and compressible.
- the dimensions B and H pv of the, for example, hexagonal valves should be in the order of 40-90% of the total thickness H of the cushion structure, which is usually between 50 and 200 mm.
- the thickness d TD of the tangential drainage layer 37 arranged towards the contacting person should be between 3 and 15 mm.
- the lower drainage layer or channels which can be made up of a finely structured layer 33 and a coarser layer 34.
- the essential element determining the cushioning effect namely the spiral spring 61, is itself the elastic actuator for the valve plate 66.
- the spiral spring 61 has a height Hs which is 60-80% of the thickness H of the mattress. The usual distances for spring or pocket spring mattresses can be maintained.
- the height H pv of the upholstery valve which is linear or cylindrical in the longitudinal direction of the upholstery, can be up to approximately 95% of the total thickness H of the upholstery, because the lower drainage 86 into the one that forms the valve seat Lower cushion 81 is integrated.
- the distance t v between adjacent linear valves can vary between approximately 0.3-H and 1.5-H.
- Diameter d B and pitch t ß of the drainage holes can be varied within a wide range, as is known from upholstery technology, of course with the aim of realizing the smallest possible pressure loss.
- the energy expenditure for the upholstery of a mattress which creates a comfortable lying climate according to the invention is orders of magnitude less than the outlay for a room air conditioning system.
- a room air-conditioning system costs many times the additional equipment of a mattress designed according to the invention.
