Definitions
- the present invention relates to a molded article for use as a reclining or seat pad, a control device for such a molded article, a method for adjusting the strength of such a molded article, a computer program product, and various uses of such a molded article.
- Shaped bodies for use as lying or seat underlay are found in a wide variety of forms, such as in the form of mattresses and cushions, or also seating in the home or in means of transport. Such items are not only used by humans, but also by animals.
- the assessment of firmness or firmness may be subject to subjective fluctuations.
- the strength of a shaped body can also change in the course of its use. Thus, although the initial strength of a molded article can be tested by trial or trial before buying. If the strength of the molded body changes over time, the user has few
- the on slatted frames it is possible, for example, to move sliders on the slatted frame in order to adjust the strength of the slatted frame.
- Another known possibility is to change the strength of the shaped body via changes in the volume or density. This is usually done with air or water bubbles, which are placed in or on the molding.
- thermoelastic and viscoelastic plastic At least a portion of thermoelastic and viscoelastic plastic, - A tempering device, which is arranged in thermal contact with the at least one portion of thermoelastic and viscoelastic plastic, and
- thermoelastic and viscoelastic plastic by changing the temperature
- thermoelastic and viscoelastic plastic is understood here to be a plastic whose strength or elasticity changes significantly with its temperature. That is, temperature-dependent strength changes are so large that they can be detected by the user without special gauges by their own perception. In addition, he is characterized by the fact that he returns after applying pressure on him only slowly to its original shape. This effect is also called slow recovery effect and leads to a pressure-reducing behavior and a very good pressure distribution.
- the one or more sections of thermoelastic and viscoelastic plastic can be specifically arranged at locations in the molded body, in which it can be easily changed Strength is particularly important, such as in the shoulder or heel area when used as a mattress or in the back area as a lumbar support when used as a seat pad.
- the one or more sections of thermoelastic and viscoelastic plastic can be combined with sections of any other materials, as conventionally used for such moldings, such as any foams, latex, steel springs or down or feather fillings.
- the section of thermoelastic and viscoelastic plastic can also be so large that it essentially forms the shaped body.
- the tempering unit serves to change the temperature of the at least one section of thermoelastic and viscoelastic plastic and thus to influence its strength. Depending on the thermoelastic and viscoelastic plastic and on the normal ambient temperature when using the molded body, a temperature increase or a temperature reduction will be necessary to achieve the desired strength.
- the tempering unit can be designed so that it leads over the entire at least one section of thermoelastic and viscoelastic plastic to a substantially homogeneous temperature distribution. But it can also be designed so that it allows to set inhomogeneous temperature distributions targeted, resulting in strength distributions over the at least one section of thermoelastic and viscoelastic plastic.
- the temperature control unit is controlled by a control device in which the correlation between the strength of the concrete molded body and its temperature is stored. This can be done in the simplest way, switched on for low strength, the tempering and it is turned off for high strength. By means of electrical switching elements, the tempering device can be switched to a higher temperature for a lower strength and to a lower temperature for a higher strength, wherein, if necessary, intermediate values can also be set.
- thermoelastic and viscoelastic plastic used in each case can also be stored as data in a memory and / or in the form of an algorithm which is accessed and / or accessed by a microprocessor to convert desired strength into a desired temperature range and to generate a corresponding output signal to the tempering device.
- thermoelastic material By controlled temperature supply or cooling of the at least one section of thermoelastic material is controlled influence on the strength taken without that a complex conversion of the molding would be necessary.
- control device By manual operation or by automatic operation of the control device can be adjusted by the user at any time just desired strength or strength distribution.
- Molded body which is set up to adjust the temperature of one or more sections of thermoelastic and viscoelastic plastic controlled by changing the temperature.
- the object is achieved by a method for adjusting the strength of a molding described above with the steps
- the object is achieved by the use of a shaped body as described above as a mattress, futon, cushion, upholstery component padding, upholstery component of a wheelchair or support for one of the aforementioned objects, in particular for decubitus prophylaxis, or as part of a chair, armchair, sofa, Wheelchair, motor vehicle, railway, aircraft seat or as a support for one of the aforementioned objects.

- Thermoplastic and viscoelastic plastics are preferably used whose resistance has a temperature dependence in particular in the temperature range between about 20 0 C and about 35 ° C.
- an electric heater is used as tempering device, which has the special feature that heat is generated via electrically conductive textile threads 14, which are arranged here centrally in section 13. They are enveloped by a shield 15 which shields electromagnetic radiation as much as possible. This is especially important if the pillow 10 should be used as a pillow.
- the material is in the arrangement shown in Figure 1 b to ensure that it has a good thermal conductivity, so that in spite of the shield 15, a thermal contact between the electrically conductive textile threads 14 and the section 13 is to change the temperature of section 13.
- the shield can also be placed further out.
- particular care should be taken to ensure that air and moisture pass through as unhindered as possible in order not to adversely affect the climate properties of the respective molded body.
- the tempering device is controlled in the example shown in Figure 1 via the control unit 11, depending on the desired strength of the pad 11, the
- Power supply in the electrically conductive textile threads 14 increases or throttles, so that more or less energy is dissipated as flow through the textile threads as heat.
- the dissipation heat radiates into section 13, whose strength changes accordingly.
- a section 17 are provided from down.
- heat deflectors 16 are provided at the transition between sections 13 and 17. They serve to prevent heat transfer from the tempering device, that is to say the textile threads 14, in the example shown in FIG. The generated heat is used here only to influence the strength, without the user would feel it.
- the heat reflectors 16 have one side that reflects more heat than the other, this side being arranged facing the textile threads 14 in the present example.
- FIGS. 2 a, b show schematically an embodiment of the shaped body with variably adjustable strength as a futon 20.
- the futon 20 is connected via a cable connection 22 to a control unit 21, which controls an electric heating on the basis of heating wires 24 as tempering device.
- the futon 20 consists essentially of the portion 23 of thermoelastic and viscoelastic plastic, which may be, for example, a polyurethane foam or other suitable thermoelastic and viscoelastic plastic.
- the futon 20 is enveloped by an allergensperrenden layer 25.
- This allergensperrende layer 25 serves mainly to prevent nesting of mites in the futon 20 and leakage of mites from the futon 20.
- the material of the layer 25 is not only allergen-tight, but also permeable to air, so as not to impair the climate in the futon 20 and to offer a pleasant lying comfort.
- a certain allergensperrende layer 25 serves mainly to prevent nesting of mites in the
- Air permeability otherwise prevents overheating of the futon 20 in the event of a malfunction of the controller 21.
- Figures 3a, b show an embodiment of the variable strength molded body as a cushion bed 30.
- the mattress base is jacked up on four support legs 32.
- the control unit 31 is integrated in the upholstered bed 30.
- the upholstered bed 30 has at the bottom a section 33 with steel springs.
- a section 35 of thermoelastic and viscoelastic plastic is arranged. Center through the section 35 extends a layer 36 with electrically conductive plastic. This layer is powered by the control unit 31 to be proportional to the flow of current
- the layer 36 may be e.g. a carrier layer of fabric or nonwoven, on which there is a support layer formed by a flexible film.
- This may be, for example, a polyurethane, which is used to increase the conductivity, e.g. Graphite is added.
- the thermoelastic and viscoelastic plastic of the section 35 itself can serve as a carrier.
- Ventilation ducts 37 are distributed in section 35 according to orthopedic considerations. They also serve the ventilation to prevent heat accumulation in the upholstered bed 30.
- a heat reflector 34 is between provided for in sections 33 and 35. It reflects dissipation heat from the electrically conductive plastic layer 36 into the portion 35 of thermoelastic material and to a user when lying on the cushion bed 30. Especially for users who fear excessive body heat loss when lying down because they have low blood circulation or are older, it may also be welcome to use the generated heat not only to set the desired strength, but also to warm the user to use.
- an embodiment of the molding with variably adjustable strength is shown as a mattress 40.
- the regulation of the temperature is over here
- the control means is combined with a pump 41, e.g. Air or water of the required temperature through the fluid channels 42 pumps.
- a pump 41 e.g. Air or water of the required temperature
- the channels can be drilled directly in the thermoelastic material. But you can also have a conversion of fluid-tight, but thermally conductive material. They may also be disposed adjacent to the portion 43 of thermoelastic and viscoelastic plastic, as long as a heat transfer exists.
- the fluid channels 42 are arranged in the illustrated example such that in particular in the region of the heels and in the region of the head support heat is supplied or removed by the fluid flow in order to change the strength. Cooling may be desired if the body heat supplied by the resting user would result in undesirably low strength.
- the mattress 40 shown by way of example in FIGS. 4 a, b has a spacer fabric 44 over the section 43 made of thermoelastic and viscoelastic plastic in order to allow air flow within the mattress 40. This reduces unwanted, because poorly controllable heat transfer from or to the user lying.
- a gel layer 45 is provided on the spacer fabric 44, which leads to a better pressure distribution, as well as a foam layer 46 in order to increase the sleeping comfort.
- the gel layer can also be used to produce a thermal contact between tempering and one or more sections of thermoelastic and viscoelastic plastic. It should be pointed out that tempering devices can also be configured in such a way that they cumulate different possibilities for heat transfer, eg fluid flow, for example for cooling, and electric heating.
- FIG. 50 Another embodiment of the variable strength shaped body as a mattress 50 is shown in FIG.
- a plurality of sections 54, 55, 56 of thermoelastic and viscoelastic plastic are provided, which are embedded in a mattress body 57 made of latex in the neck, lumbar and heel area.
- Each of these sections 54, 55, 56 is connected to its own control unit 51, 52, 53. This makes it possible to regulate the strength in the neck, lumbar or heel area regardless of the strength in the other areas as needed.
- a single control unit can also be provided, which can receive inputs for the individual sections 54, 55, 56 and convert them into control signals for the respective temperature control units.
- FIG. 6 shows an embodiment as a mattress overlay 61 which is placed on a conventional mattress 60.
- the support 61 is essentially formed by the section 64 of thermoelastic and viscoelastic plastic, which is penetrated by a heating wire 63 and is adjusted by a control unit 62 in their strength by appropriate temperature regulation.
- 61 recesses 65 are provided on the user-facing side of the support. The distribution of the recesses 65 on the support 61 is advantageously carried out according to orthopedic considerations.
- FIG. 1 An embodiment as a support, namely as a seat pad 71 for a wheelchair 70 is shown by way of example in FIG.
- the seat pad 71 consists essentially of a foam part 74, in which two sections 72, 73 of thermoelastic and viscoelastic plastic in the neck and in the lumbar area are embedded. These sections 72, 73 are regulated by a tempering device, not shown here in their temperature and thus their strength at will.
- the tempering is designed as an electric heater, which is powered by manually operated wheelchairs via an additional battery and electric wheelchairs on the existing power supply with electricity.
- the control unit 75 is disposed on the armrest to be easily accessible and operable for the user. It should be noted that embodiments as a support can also be dimensioned smaller, so that they cover, for example, only a part of a mattress or a seat, such as the back, the neck, the lumbar region or others.
- FIG. 8 shows by way of example an embodiment as seating 80. It can be a sofa, an armchair or a cushioned chair with armrests.
- a control unit 81 is integrated with the seating 80 and provides the desired strength of the thermoelastic and viscoelastic plastic pads 82, 83 by being brought to a temperature corresponding to the desired strength by separate heating wires 84, 85 respectively.
- each heating wire 84, 85 can be controlled separately in order to adjust the strength in the pads 82, 83 regardless of the other pad.
- an intermediate change in strength is often required by the user and also for health reasons.
- FIG. This is a seat 90, as it could be used in an airplane, on the train or in a vehicle such as car, bus or truck. Also possible is the design as an office chair.
- the upholstery 94 is the thermoelastic and viscoelastic plastic backrest to which heating wire assemblies 92,93 are contiguously provided in two areas. Both Thompsondrahtan effet 92, 93 can be independently controlled by the attached to the armrest 95 control unit 91 to set a desired strength of the pad 94 in the two back regions. Even a possibly automatic change of strengths during the sitting period can e.g. As a lumbar support have orthopedic benefits, but also prevent over-fatigue and even microsleep. In particular, on long-haul flights, a variable-strength seat results in improved circulation of the overlying skin, which is beneficial to both passengers and crew. This is also advantageous in office chairs.
- Main components are a desired strength distribution determining unit 105, a microprocessor 106 serving to determine the corresponding target temperature distribution from the SoII strength distribution, and a unit 107 for applying this target temperature distribution via a suitable interface 108 to issue a temperature control unit.
- the unit 105 for determining a desired strength distribution is connected in the illustrated example to a user interface 101. This may be an operating display, via which a manually desired current strength value, possibly a preset strength distribution over the entire strength-variable seat or couch pad or a temporal
- Strength history is entered or selected from preset options.
- the user interface 101 can also be designed as a remote control.
- an operating switch can also be provided, which can be switched back and forth between two strength values.
- the control unit is thus arranged to cooperate with one or more tempering devices by converting an input of a desired strength into a desired temperature range, be it mechanical, electrical, electromechanical or electronic, and from this a corresponding output signal for the tempering device (s) is generated ,
- the sensor (s) 102, 103, 104 are connected to the unit 105 for determining a desired strength distribution.
- the sensor (s) 102, 103, 104 may be e.g. be about sensors that respond to pressure or movement and so register body movements. It may also be sensors that detect sleep or wake phases based on body functions. These include sensors to determine the respiratory rate, the oxygen content in the blood, the heart rate or the blood pressure. A change of these parameters may e.g. initiate a time course of a strength distribution, such as changes in strength at different locations of a mattress during a sleep cycle with, for example, a softer strength distribution in the fall asleep, firmer strengths in the subsequent deep sleep phase and again softer strengths during the REM phases. The transition from one sleeping phase to the next can be detected by the sensors 102, 103, 104.
- the sensors can also be temperature or strength sensors, by means of which the current temperature or strength can be controlled to determine whether the desired state has already been reached.
- control device 100 may be set for periodic strength changes in the entire mattress or only in certain areas, without requiring manual operation by the bedridden user would be necessary.
- the regular strength changes support a good and regular circulation of all skin to avoid bedsores.
- the time-variable strength distribution can also be used to prepare the body of the person lying down for waking up by increasing the strength at a specific wake-up time.
- the unit 105 determines a desired time-strength distribution (step 203). From this, the microprocessor 106 determines the time course of the necessary temperature distribution (step 205).
- the temperature values may be e.g. be read from stored data tables and / or calculated.
- the specific thermo-and visco-elastic properties of the relevant section, its geometry as well as the geometry and concrete properties of the tempering device used should be taken into account.
- the individual parameters can be determined by simple measurements for each thermoelastic and viscoelastic plastic.
- the desired temperature distribution determined in this way is set via output from the unit 107 via the interface 108 to the tempering device (step 207). In order to increase the comfort of the user, it is also preferable to specify temperature gradients for setting the desired temperature distribution, so that the change in strength is carried out neither too quickly nor too slowly.
- Strength distributions can be dispensed with in simpler variants of the control device on a microprocessor to convert inputs about a desired strength in a desired temperature range or a desired temperature and to generate a corresponding output signal to the tempering.
- the temperature control unit can be switched over between a temperature which corresponds to a higher strength and a temperature which corresponds to a lower strength via a switch.
- thermoelastic and viscoelastic plastics are used which correspond to significantly different temperatures but which, for reasons of minimized energy consumption and a faster change of strength also not too far apart.
- temperature steps of about 1, 5 ° C to 2.5 ° C offer.
- FIG. 12 shows by way of example a possible construction of a shaped body.
- the molded body has an upper part 121 and a lower part 122, which are shown in the separated state. While the upper part 121 has two parallel grooves in the manner of grooves 125, the lower part 122 has two complementary strips in the manner of springs 124. As a result, upper and lower parts 121, 122 can be easily connected and disconnected again if necessary. However, other means than groove 125 and spring 124 may be provided to allow a positive connection of the parts.
- a recess 123 is provided, in which the tempering and / or the control device can be partially or completely admitted.
- the tempering and / or the control device can be partially or completely admitted.
- the upper and lower parts 121, 122 are made of thermoelastic material.
- thermo-elastic material may also be embedded in one or more parts.
- FIG. 14 schematically shows a further embodiment of the molding as a mattress 140 in section.
- the thermoelastic viscoelastic foam portion 143 is provided with an upper portion 146 and a lower portion Section 145 of a plastic, combined in the present example of a foam having a lower strength at room temperature than the portion 143 of thermoelastic viscoelastic foam.
- the sections 145, 146 of a conventional, ie non-thermoelastic and viscoelastic foam in which no noticeable temperature dependence of the strength in particular in
- the sections 145, 146 are integrally formed. In other variants, they can also be designed in several parts. Likewise, further sections may be provided from a conventional or a thermoelastic and viscoelastic plastic. In some variants, it is also possible to dispense with an upper section 146 so that a lying leg rests on the section 145 of thermoelastic viscoelastic foam.
- thermoelastic viscoelastic plastic which is relatively strong at room temperature
- an underlying portion of softer plastic at room temperature the softness of which remains substantially constant even at temperatures above that, enhances the effect of changing the strength of the molded body having these portions, especially at higher levels
- Temperatures for example in the range between about 30 0 C and body temperature
- thermoelastic, viscoelastic plastics show a lower strength change than at lower temperatures, for example in the range between room temperature and about 30 0 C.
- the section of thermoelastic, viscoelastic plastic by appropriate temperature below a certain strength, additional softness of the underlying soft plastic portion is noticeable, previously from the solid portion of thermoelastic viskoelasti plastic was covered.
- thermoelastic, viscoelastic plastics can also be combined for this purpose, as long as they have different strengths at different temperatures.
- a heating fleece 142 which is connected via a heating cable with a control device 141 and is applied directly on top of the section 143 of thermoelastic, viscoelastic foam, the temperature of this section 143 changed to achieve a strength change.
- the heating fleece can be replaced, inter alia, by a heating foil or a textile of heating filaments.
- the respective current temperature is controlled by the temperature sensor 147, which is arranged at a distance from the tempering device formed here as a heating fleece 142.
- two, three or more temperature sensors can be provided.
- the temperature signal is passed via the sensor cable 149 to the control device 141, which in turn determines depending on the desired strength and the necessary temperature on the one hand and the current temperature, whether a temperature change by the temperature control is necessary or not and a corresponding signal on the heating cable 148th to the Schuvlies 142 passes.
- the position of the temperature sensor 147 at a distance from the heating fleece 142 ensures that the plastic temperature and not the actual temperature of the heating fleece 142 is measured.
- the temperature sensor 147 is particularly preferably arranged on the side of the heating fleece 142 facing a lying side. This also takes into account the influence of the body heat of the person lying on the temperature of the plastic and thus also on the strength. By placing the temperature sensor closer to the horizontal or closer to the respective temperature device, the control unit weights the respectively considered influence of these heat sources accordingly.
- the heating fleece 142 is provided with a metal coating 144a, which serves to shield electromagnetic radiation emitted by the heating fleece from the horizontal.
- the metal coating 144a is grounded.
- it has a grounding cable 144b.
- thermoelastic material 54 Section made of thermoelastic material 55 section of thermoelastic material
