Description

The innovation relates to a vibration device for introducing and / or disseminating structure-borne sound waves into a body, comprising an actuator, a control unit controlling the actuator, and a surface element operatively connected to the actuator, which can be excited by the actuator for spreading body waves. Furthermore, the innovation relates to a sitting or lying device, such as a cushion, which is equipped with a vibration device according to the innovation.

In the prior art, vibration devices are known which are mounted, for example, on a chair to stimulate this to vibrate, so that on a person sitting on the chair, a vibration can be supplied. This principle requires a high and inefficient energy expenditure, since the entire chair must be set in vibration. Especially occur in this principle undesirable noise or at least noise to an undesirable extent.

Other vibration devices are off DE 20 2012 012 970 U1 known. DE 20 2012 012 970 U1 teaches an arrangement for transmitting structure-borne sound waves to a body, wherein the arrangement comprises a device which has a bearing area with a support surface and the device with the support surface can be placed on the body and at least one exciter device is provided, wherein the exciter device is arranged on the device is that the support area for generating body sound waves can be excited with a sound energy wherein the structure-borne sound waves are inducible with the sound energy by means of the support surface in the body. Here, the support region has a rigid structure in order to ensure a good vibration transmission and to be adaptable to a predetermined surface shape. In this case, it is disadvantageous that the support surface offers only little comfort for the body to be acted upon by the vibrations. Although an adaptation of the rigid support surface is provided to a predetermined surface shape to obtain a possible comfort gain, but the comfort is then still unsatisfactory and the scope of this correspondingly shaped support surface is very limited, since the shape is immutable adapted to a particular application.

The innovation is based on the object, a vibration device and equipped with a corresponding vibration device sitting or lying device according to the preamble of claim 1 and 18 such that the comfort of a person to be impacted with the structure-borne sound waves is increased and at the same time despite use a small-area actuator whose vibrations are as homogeneous as possible, are delivered over a much larger area compared to the size of the actuator. Furthermore, it is an object of the innovation that, despite the high level of comfort, there are no or no significant restrictions on the areas of application, for example on a chair, an armchair or a couch. In the application for a sitting or a reclining device whose sitting and lying comfort should be limited as low as possible and at the same time be as homogeneous as possible vibration distribution and / or vibration introduction on or in the person to be acted upon.

This object is achieved by a vibration device with the features of claim 1, as well as by a sitting or lying device with the features of claim 18. Advantageous developments of the innovation will become apparent from the dependent claims 2 to 17 and 19 to 29.

The core of the innovation is considered that the surface element comprises at least one planar sheet and the at least one surface of the surface element is at least temporarily elastic, wherein the at least one sheet or at least one of the sheets of foamed plastic, preferably of foamed polyvinyl chloride, from foamed Polystyrene, made of foamed polyurethane or foamed polysiloxanes is formed. This allows the best possible homogeneous and areal conduction / propagation of the vibrations of a basically point-acting actuator and thus a simple and inexpensive construction of the vibration device with a high degree of flexibility of the same. Since a basically punctually acting actuator can be used and a surface vibration is spread by the surface element, the number of actuators required to generate a surface acting for the user vibration can be kept low. Due to the elastic configuration of the surface element, this adapts to the body region / contour of this person when exposed to the person to be impacted with the structure-borne sound waves, while at the same time a vibrational feeling is created by the vibration conduction properties in the person, although the surface element only by a selective vibration source (the actuator) is excited. This saves on manufacturing costs, not only ensures comfort in using the device itself, but passes the comfort of the underlying piece of furniture or object in a high degree to the person. In other words, despite circulation or incorporation of the vibrating device according to the invention Comfort function of the upholstery of the seat and / or deck furniture not or hardly affected for the user. The literature argues that the means (surface element) stimulated by an actuator should be designed as stiffly as possible in order to ensure good vibration excitation, vibration initiation and / or vibration propagation. Surprisingly, it has been found by experiments that even temporarily elastic or permanently elastic surface elements can have a sufficiently good vibration excitation and vibration propagation property. Also, the experiments have shown that particularly good results are achieved when the at least one sheet is made of a foamed plastic. Particularly advantageous results have resulted in the use of foamed polyvinyl chloride or of foamed polystyrene. The structure of the foamed materials is extremely well suited for good vibration transmission / propagation with a high degree of flexibility. Also, with the use of foamed plastic for the sheets and in particular the use of foamed polyvinyl chloride or foamed polystyrene is accompanied by a simple design of the vibrating element to the intended application. Thus, for example, a standard surface element with a predetermined dimensioning can be adapted to the desired dimensioning in the simplest manner of machining (for example, sawing). Also, the sheet body could have predetermined breaking points for easier separation of unnecessary Flächenköperabschnitten. Thus, a simple integration of the vibration device is achieved at the same time low variance of sheets and / or the vibration devices themselves both for newly manufactured sitting or lying devices, as well as for the equipment of existing sitting or lying devices.

A temporary elastic sheet is understood to mean a sheet made of a material having a shape memory property, such as a shape memory polymer. Called the shape memory property or shape memory effect, the material apparently "remembers" its former external form, despite a strong transformation in the meantime, and resets it to its original shape after a stimulus. Thus, the surface element can deform at least partially plastically, but after the action of a stimulus, for example, a heat above or below a temperature threshold, move back to the original form. Also, the surface element in any deformation layers could maintain a defined basic elasticity, d. H. have an elasticity to a limited extent within the assumed basic shape of the surface element. As an essential feature of the temporary elastic surface element is in addition to call the good vibration line. In the case that the surface element consists of at least two surface bodies, the shape memory property can be realized in at least one or in all surface bodies.

The excitation of the vibration device generates in a preferred embodiment substantially frequencies of tactile stimulation on the body between 2 and 750 Hz, more preferably substantially frequencies of tactile stimulation on the body between 5 and 300 Hz.

The excitation of the vibration device is preferably carried out on the basis of an audio signal, for example, a line-out audio signal represent the basis of the vibration excitation, and based on a preferably variable filter a dependent of the audio signal vibration output done by the vibration device. Alternatively or additionally, a frequency generator or a mechanically or otherwise excited frequency generator source can also be used.

In an advantageous embodiment, the material of the at least one sheet has a temperature resistance in the range from -40 to + 100 ° C, preferably from -35 to + 85 ° C. Foamed plastics, especially foamed polyvinyl chloride or foamed polystyrene having the aforementioned temperature resistance are particularly suitable with regard to the homogeneous vibration propagation and the given flexibility.

It is also advantageous if the material of the at least one sheet body has an E-modulus in the range of 0.2 to 5 MPa, preferably an E-modulus in the range of 0.5 to 2.5 MPa, particularly preferably an E-modulus in the range of 0.7 to 1.1 MPa. Foamed polyvinyl chloride or foamed polystyrene in the specified E modulus ranges show a high degree of vibration propagation property with high elasticity.

Additionally or alternatively, it is advantageous if the material selected for the sheet is in terms of elongation at break, breaking strength, thermal conductivity and / or impact resistance in the areas specified below.

For the elongation at break and / or breaking strength, the following value ranges were found to be advantageous: 10.00 to 75.00 MPa, preferably an elongation at break and / or a breaking strength in the range from 17.00 to 50.00 MPa, especially preferably an elongation at break and / or a breaking strength of 24.00 to 29.00 MPa.

Alternatively or additionally, it is advantageous if the material of the at least one sheet has a Charpy impact strength in the range of 5.00 to 45.00 KJ / m ² , preferably a Charpy impact strength in the range of 10.00 to 30.00 KJ / m ² , more preferably has a Charpy impact strength in the range of 12.50 to 17.50 KJ / m ² .

Finally, foamed plastics have further been found to be particularly suitable, which have a thermal conductivity in the range of 0.03 to 1.5 W / m ° C, in particular in the range of 0.05 to 0.10 W / m ° C.

A uniformly closed cell structure for the foamed plastic plates is also advantageous for the use according to the invention. The closed cell structure ensures good vibration transmission, whereby the cell geometry itself ensures a high degree of elasticity.

Furthermore, it has proved to be advantageous if the at least one sheet of a uniform material, this allows a simple and inexpensive production of the sheet. If the surface element comprises several surface bodies, it is advantageous if all surface elements of a surface element each consist of a similar or the same material, this also allows a simple and inexpensive production. By the same material is meant material having an equal or similar density (+/- 15%), the same or similar modulus of elasticity (+/- 15%) and / or the same or similar density to modulus ratio (+/- 15%). Furthermore, the same material may preferably also comprise identical material for a plurality of sheets of a surface element.

At least one, preferably all surface elements of a sheet have a disk-like shape and have a layer thickness of 0.75 to 6 mm, preferably a layer thickness of 1.5 to 3 mm. In another production-technically favorable embodiment of the innovation, the layer thickness of all surface elements of a sheet is selected with a maximum deviation of 25%, preferably selected with a maximum deviation of 10%, particularly preferably with a maximum deviation of 5%.

In addition, it has proved to be particularly advantageous if at least two surface elements of the surface element are movably connected to one another in such a way that at least one relative movement of the at least two surface elements in a translational degree of freedom, preferably in two translational degrees of freedom, is made possible. The use of the movable connection is particularly preferred achieved a connecting means. Through this enabled relative movement is achieved that with external application of force to the sheet during its elastic deformation, lower stresses occur within the surface element and a compensating movement of the respective sheet is largely executable independently of adjacent sheets. It can be increased in a structurally simple manner by the at least partially movable layer structure for the surface element whose flexibility. A key point here is that this elasticity enhancing measure has little to no effect on the body vibration excitation, body vibration initiation and / or body vibration propagation function of the surface element. The design of the connecting means can be versatile, so even the provision of one or more bands can lead to an effective connection of at least two sheets whose mobility is made possible along an axis perpendicular to the course of the band. In addition or as an alternative to a banderole, the connecting means can also be designed as a positive-locking profile or as an adhesive strip (for example adhesive tape) which overlaps at least two sides and can abut, for example, on area-wise edge regions of the planar element.

In a further example, engagement elements of an adjacent surface body can be received in correspondingly formed guide recesses on a first surface body, this in turn would allow a movable in one or two translational degrees of freedom attachment of the surface body. The connecting means may be a separate, separate from the sheets body. Alternatively, the connecting means may be formed as an integral (one-piece) component region of at least one sheet.

The two sheets may preferably each be disc-like, aligned parallel to each other and arranged adjacent to each other.

It has proved to be expedient to arrange the actuator in the central region of the main extension surface of the planar surface element, preferably centrally and / or flatly on a surface region, preferably resting on the main extension surface of the surface element on a contact surface of the surface element. The plane Edition of the actuator on the planar surface element allows a high efficiency in the excitation of the surface element by the actuator. Alternatively or additionally, at least one actuator in a recess of the surface element may be used at least partially, preferably the recess could be an opening within which the actuator protrudes at least partially, particularly preferably the actuator is arranged perpendicular to the main extension plane of the surface element centrally within the opening. The actuator is preferably fixed in a material or form fit to the surface element. The fixation can be done in particular by gluing, screwing, stapling, riveting, fusing. In particular, it has proven to be advantageous to fix the actuator to the surface element by means of an elastic adhesive (eg neoprene adhesive or body adhesive), which entails the advantage, inter alia, that no or only slight damage occurs when the surface element deflects. Stiff behaving "area comes at the fixing of the actuator.

In order to further increase the efficiency of the excitation of the surface element by the actuator and its degree of homogeneous vibration radiation, it has proved to be advantageous if, in addition to the contact surface of the actuator with the surface element, in addition by at least one einendseitig acting on the actuator transmission means on the other end with at least one , Actuator spaced from the insertion region of the surface element is operatively connected. This active connection of the actuator with the introduction region via the transmission means preferably takes place in such a way that structure-borne sound waves generated by the actuator at least one transmission medium can be indirectly or directly induced in the at least one introduction region.

As a transfer agent, an adhesive tape can be used in the simplest case. The transmission means can be mounted in the production under a bias (tension), this has the advantage that when pulling movements on the transmission means increased or always a basic train load applied to the transmission means and this even if caused by the actuator load changes a quick response the transmission means and thus a quick response of the Einbringbereiche or the sheet are desired. This bias is particularly advantageous when the user of the vibration device or the sitting or lying device is only a slight application of force to the surface elements.

The transfer means can be fastened to the introduction areas and / or to the actuator by a material-locking connection (eg gluing) or positive connection (eg screwing or riveting). The transmission means itself may preferably be formed as a metal or textile tape.

It is also advantageous if the at least one introduction region has a distance from the actuator which corresponds to at least one third of the smallest distance of the actuator to the outer boundary in the main extension plane of the surface element, preferably the at least one introduction region is arranged on an edge region of the surface element, especially Preferably, the at least one introduction region is arranged on the edge of the surface element. The fact that the introduction region has a certain minimum distance from the actuator significantly increases the effectiveness of the actuator surface element group. In particular, when the insertion region is arranged in the edge region or at the edge of the surface element, a similar or identical excitation can be performed by the actuator at two points at the same time, this leads to a more homogeneous and faster excitation of the surface element to a desired frequency. The "unification" of the excitation of the surface element by the actuator also allows a gain in comfort, as well as for the user of the vibration device and / or the sitting or lying device on its contact surface a more uniform vibration is perceptible. Structurally, a transmission means encompassing the wheel side could be realized by an adhesive tape holding the actuator on the surface element, the two ends of which are guided over the edge of the surface element and fastened (glued) to the surface of the surface element facing the actuator.

Hereinafter, the dimensions of the essential components for a particularly preferred embodiment are set forth. For example, if the actuator, preferably at maximum vibration deflection and / or maximum vibration expansion, a height of 1 to 30 mm, preferably one of the actuator has a height of 8 to 25 mm, particularly preferably the actuator has a height of 15 to 20 mm, wherein the overall height relates to the maximum extent of the actuator in the final assembly state with the surface element, which is present at right angles to the main extension plane of the surface element. Also, the surface element may have a maximum length in the main extension plane of the surface element of 75 to 750 mm, preferably from 100 to 500 mm, particularly preferably from 200 to 350 mm. Finally, the surface element and / or all sheets may have a height of 0.8 to 75 mm, preferably from 1.0 to 4.5 mm, particularly preferably from 1.5 to 3.0 mm. The overall height of the surface element is in this case the present in the final assembly state at right angles to the main extension surface of the surface element aligned extension.

For the aforementioned dimensions of the actuator and / or the surface element and / or sheet it is advantageous if the actuator used has a power in the range of 3 to 12 watts, preferably a power in the range of 5 to 9 watts. These power ranges form for the specified dimensions of the essential components a sufficiently effective and at the same time a high degree of comfort bidding preferred embodiment of the vibration device according to the innovation.

A further advantageous measure is when the control unit with at least two surface elements and with at least two each, a surface element associated actuators form a pre-assembly, preferably form a non-separable in itself pre-assembly. Preferably, in this case each surface element is assigned exclusively an actuator. This pre-assembly unit may preferably form an inherently integral and / or non-separable pre-assembly unit. An inseparable connection in this context may be a non-destructively separable connection and / or may provide such attachment of the connection partner that does not provide for disengagement, e.g. As a bond, rivets or the like. In the case of the pre-assembly unit, the vibration device can be mounted on an object (eg sitting or lying device) in a simple, quick and relatively error-avoiding manner. For example, the pre-assembly may be designed by the manufacturer of the vibration device as a functional in the delivery condition assembly / pre-assembly, so that a functional test without later disassembly and reassembly is executable. Also, the manufacturer of the objects to be provided with the vibratory devices demands only little know-how / low skill for the assembly, whereby the assembly effort and the susceptibility to errors can be kept low.

In order to enable the widest possible range of application for the vibration device according to the innovation, it is advantageous if the control unit in the final assembly state has a height which is equal to or less than the overall height of the actuator. Thus, the control unit and actuator in a plane next to each other, possibly also spaced next to each other are arranged so that the height of the object to be provided with the vibration device by the vibration device increases minimally.

A further advantageous embodiment provides that the control unit is in operative connection with an amplifier, a power supply and / or an energy store. In particular, it has proven to be advantageous if the energy storage is wirelessly charged to an external power source, such a wireless power consumption, for example, by an inductive charging, this has the advantage, for example, that held on the control unit receiving element no externally visible interfaces must be, d. H. in the case of a cushion provided with the vibration device according to the invention, this cushion has no charging socket on its surface. Alternatively or additionally, the control unit may comprise an operating unit, via which the user can control the intensity or local distribution of the structure-borne sound waves at one or more surface elements. Preferably, the control unit is wirelessly coupled to the control unit, so that - as in the example above for the inductive charge - mentioned advantages.

Alternatively or additionally, the actuator in its main extension plane has an area of 10 to 10,000 mm ² , the actuator preferably has an area of 50 to 7,500 mm ² in its main extension plane, particularly preferably the actuator has an area of 100 to 6,000 mm ² in its main extension plane Most preferably, the actuator has an area of 225 to 5026 mm ² in its main plane of extension. This limitation of the actuator to be used leads to a so-called point actuator, that is, an actuator that sends its vibrations in a point-like manner. These actuators are inexpensive and especially advantageous for those applications which require flexibility of the overall system or subsystem (seat pads, upholstery). This is made possible by the small size of the actuators that lead to a no or barely noticeable impairment of seating comfort. In other words, small actuators allow their usually rigid design is barely noticeable or not felt by the user. So that the vibrations for the user are not perceptible as point sources, the surface elements and / or surface elements act as homogenizing sound propagation elements. In particular, the small-scale point actuators make it possible to easily equip constructions of lying and / or seating devices to be newly designed or already existing with the vibration device according to the invention.

Furthermore, in the case of the obstruction of an energy storage device, this can likewise be installed in a plane to the control unit and / or in a plane to the actuator, so that despite the provision of an energy storage, the overall height in the transverse direction to the longitudinal extent is not or only slightly increased.

In a particularly advantageous manner, the vibration device according to the invention is used within a sitting or lying device, wherein the at least one sheet of the vibrating device is disposed between a reference layer facing a sitting or lying user and a comfort layer located more remote from the reference layer relative to the reference layer, preferably the comfort layer is connected to a seat or recliner frame. Characterized in that the at least one sheet of the vibration device is formed elastically, it is possible to arrange the vibrating device close to the cover layer and / or directly to the cover layer, without having to take greater loss of comfort for the seat or couch user in purchasing. The sitting or lying device, for example, a padded chair, a cushioned lounger or a cushion itself - for example, a pillow - be. Also, the seat or reclining device may comprise part of a seating or reclining device, such as the seat cushion pad (eg, vehicle seat surface), a back surface (eg, vehicle seat back), armrests (eg, in a vehicle door trim panel) and / or in a vehicle center armrest), a steering wheel padding and / or a neck / headrest padding. It is essential here that the sitting or lying device comprises an at least temporarily elastic body (comfort layer) acting on the sitting or lying device, which gives way at least temporarily when the sitting or lying device is acted upon. The reference layer and / or the reference layer can be, for example, a textile material.

It is furthermore proposed that an intermediate comfort layer be arranged at least in regions between the surface element and the cover layer. The intermediate comfort layer can further increase the comfort for the seat or couch user. By virtue of the fact that the intermediate comfort layer has a higher or identical vibration conductivity (lower vibration damping property or also a higher vibration-conducting property) than the comfort layer, it is possible to ensure that the vibrations generated by the vibration device act primarily on the intermediate comfort layer facing the seat or lying user.

In an advantageous embodiment, the comfort layer and / or the intermediate comfort layer have an at least temporarily elastic property, preferably the comfort layer and / or the intermediate comfort layer are / is a cushion layer and / or a memory effect comfort layer provided with a memory effect and / or or memory effect intermediate comfort layer formed. The upholstered layer allows comfort as is customary in upholstered furniture. In particular, the combination of an elastic surface element with a cushion layer allows outstanding adaptability to the user, without the actuator could be selectively perceived / localized as a structure-borne noise source by the user, since the surface element ensures a planar structure-borne sound radiation.

Furthermore, it has proved to be advantageous if the elastic vibration layer surrounds the control unit and / or the energy storage unit at least laterally, preferably surrounds the elastic vibration layer, the control unit and / or an energy storage in a plane completely (with the exception of any existing connection means such B. connecting cables).

According to an advantageous embodiment, the memory effect comfort layer and / or memory effect intermediate comfort layer comprises a shape memory material, in particular a shape memory polymer, preferably the shape memory material is reset by thermal, optical and / or magnetic influence in an original shape state. For example, a longer yielding of the shape memory polymer and the concomitant transmission of body temperature results in a more compliant structure which, after cancellation of contact and cooling of the pad, eventually with some delay, reverses the deformation and returns the structure to its original shape declining.

In a further advantageous embodiment, the comfort layer and / or the intermediate comfort layer has a density of 16 to 85 kg / m ³ , preferably a density of 33 to 45 kg / m ³ , particularly preferably the memory effect comfort layer and / or the Memory effect intermediate comfort layer has a density of 16 to 85 kg / m ³ . These high density values lead to a good vibration transmission property of the materials, despite its elastic behavior. Outstanding here is the use of the memory effect material, since this may have a basic elasticity, which is temporarily changed by temperature change. For example, a memory foam material such as "Tempur" offered by Tempur-Pedic can be used. This memory foam (also called memory foam) is already used in viscoelastic mattresses.

In a further advantageous refinement, the intermediate comfort layer has at least one first region at least in the vicinity of the actuator and a second region arranged further from the actuator, the vibration-conducting properties of the first and second regions being different, preferably the vibration-conducting property of the first region being less than that of the second area. In other words, the first region acts vibration-damping than the second region. Thus, without this measure, the perceptible increased near the actuator Submit vibrations attenuated to a person as the vibrations that are transmitted through the second areas to a person, so that a total of a more homogeneous vibration transmission is perceptible to the person. In the vicinity of the actuator, this means that this area is closer to the actuator than the more remote area. By way of example, the first region of the intermediate comfort layer, which is closer to the actuator, can be at least 30% (preferably at least 50%, particularly preferably at least 70%) in its vibration transmission property by choice of material and / or geometric design (for example recesses) and / or coating. ) ensure lower vibration transmission, as a second, the actuator remote arranged portion of the intermediate comfort layer. The first area of the intermediate comfort layer closer to the actuator can consequently also be referred to as a damping layer. The idea underlying this embodiment of equipping the intermediate comfort layer with different "damping properties" depending on the distance to the actuator is not limited to a first and a second range, but instead three or more ranges with at least partially different degrees of damping may be provided Preferably, the magnitude of the increase in the distance to the actuator decreases. Finally, the provision of different damping properties as a function of the distance to the actuator can be applied not only to the intermediate comfort layer, but additionally or alternatively also to the comfort layer. In particular, when the comfort layer rests directly or indirectly on a sitting or lying frame or generally on a rigid support, it may be provided depending on the distance to the actuator and / or depending on the configuration of the seat or couch frame or carrier different areas in terms of To provide cushioning property of the comfort layer, for example, so as to reduce or prevent a vibration energy input in the rigid sitting or lying frame or carrier, so that the vibration energy of the actuator can be amplified used to vibrate a person.

The regions having different vibration-conducting properties can be achieved, for example, by means of an intermediate comfort layer formed in several pieces in the main extension plane thereof, the respective pieces of the intermediate comfort layer having different vibration-conducting properties. Alternatively or additionally, an integral, at least partial region of the intermediate comfort layer, which comprises both the first and the second region and for this purpose has different vibration-conducting properties in the two regions, can have these different vibration-conducting properties through material recesses and / or through coatings.

In a further advantageous embodiment, the second region of the intermediate comfort layer and a third region of the intermediate comfort layer are formed from the same or identical material. Alternatively or additionally, the second and the third region are arranged spaced apart from each other at least in regions, preferably, the first region of the intermediate comfort layer is arranged within a distance of the second and third regions of the comfort layer. It is also possible to provide more than three regions of the intermediate comfort layer, which have at least partially different properties with regard to the vibration line.

• – eine Nettorohdichte (nach ISO-845 ) von 17 [kg/m³],
• – eine Stauchhärte 40% (nach DIN EN ISO 3386 ) von 2,5 [kPa],
• – eine Zugfestigkeit (nach DIN EN ISO 1798 ) von größer 65 [kPa],
• – eine Bruchdehnung (nach ISO-1798 ) von größer 100[%] und/oder
• – einen Druckverformungsrest (nach DIN EN ISO-1856 ) größer 6 [50%/70°C/22 h].

As a material for the first region of the intermediate comfort layer PU and / or polyurethane foam (polyurethane) has proven particularly suitable. Alternatively or additionally, it is advantageous if the material properties of the first region of the intermediate comfort layer have the following:

• - a net density (according to ISO 845 ) of 17 [kg / m ³ ],
• - a compression hardness 40% (after DIN EN ISO 3386 ) of 2.5 [kPa],
• - a tensile strength (acc DIN EN ISO 1798 ) greater than 65 [kPa],
• - an elongation at break (after ISO-1798 ) of greater than 100 [%] and / or
• - A compression set (nach DIN EN ISO-1856 ) greater than 6 [50% / 70 ° C / 22 h].

If the value of the elasticity can be determined, it is advantageous if the comfort layer and / or the intermediate comfort layer has a density of 16 to 85 kg / m ³ , preferably a density of 33 to 45 kg / m ³ , particularly preferred that the Memory effect comfort layer and / or the memory effect intermediate comfort layer has a density of 16 to 85 kg / m ³ .

In addition, it has proved to be advantageous if at least partially a reference layer is arranged on the side facing away from the cover side of the seat or reclining device, preferably the comfort layer is at least partially bounded by the reference layer, particularly preferred is the reference layer with the reference layer at least partially directly connected. In other words, the reference layer is the "reference layer" of the sitting or lying device opposite the reference layer. In a particular embodiment, cover layer and reference layer can be formed from a similar or identical material or even form a common part (both material and geometry identical). Also can cover layer and Reference layer connected directly to each other, z. B. sewn. Alternatively, a hose-like body, e.g. As a shrink tube, as at the same time covering layer and reference layer forming used for the sitting or lying device. Overall, for example, the cover layer and the reference layer can form the cover of a pillow.

For a particularly advantageous mode of operation, it has been proven that the vibrating device is arranged between the reference layer and comfort layer, that the sound emitted from the vibrating body sound waves are subject to a higher body sound attenuation until reaching the seat or lying frame, as the reference layer reaching structure-borne sound waves, preferably this is achieved by a corresponding, structure-borne noise damping design of the comfort layer with respect to the intermediate comfort layer and / or by a corresponding, not or hardly köperschalldämpfende interpretation of the intermediate comfort layer. In other words, the comfort layer is more vibration damping than the intermediate comfort layer. With these measures can be achieved that the vibration energy (kinetic energy) can be provided primarily where it is desired, namely at the contact surface to sitting or lying user and not on any existing sitting or lying frame.

The actuator can advantageously contact the surface body on its first main extension surface and be surrounded at least laterally by an elastic oscillation layer; the actuator is preferably in contact with a counter surface body on its second main extension surface opposite the first main extension surface. This allows a compact design of the device according to the invention. This can be further increased if the elastic damping layer further surrounds a control unit and / or an energy storage at least laterally.

A manufacturing technology favorable embodiment is achievable if the mating surface body similar, preferably identically formed as the sheet. In the best case, a common part could be used for mating surface body and surface body.

The following dimensions of the essential elements of the sitting or lying device indicate a particularly compact and at the same time effective and high efficiency exhibiting embodiment. Here, the thickness of the cover layer to the overall height of the surface element may have a ratio of 1: 1 to 1: 5, preferably from 1: 1 to 1: 3. Alternatively or additionally, the thickness of the cover layer is selected to the common height of the surface element and the actuator so that a ratio of 1:10 to 1: 100 is present, preferably a ratio of 1:20 to 1:80 is present. Also, the common height of cover layer and intermediate comfort layer to the height of the comfort layer, a ratio of 1: 1 to 1: 5, preferably from 1: 1 to 1: 3.

Furthermore, in an additional or alternative embodiment, the height of the comfort layer to the common height of the planar element and the actuator may have a ratio of at least 1.0, preferably a ratio of at least 3.0. These dimensions and these ratios are each directed to a surface element for structure-borne sound transmission, which in particular in the frequency range of 5 to 300 Hz has a high efficiency and effectiveness. Since humans have a high tactile sensitivity at frequencies around 250 Hz, a defined working range of the vibration device and the seat or reclining device equipped with it should be achieved by the above conditions.

According to a further embodiment of the innovation, it is provided that the sitting or lying device with a heating element is equipped, preferably, the heating element is part of a pre-assembly. The heating element makes it possible to provide the sitting or lying device additionally with a heating function, it makes sense to provide the power flow for the heating function from the same energy source (energy storage or power supply) as the actuator. In particular, for therapeutic purposes, it has proved to be helpful if the person who uses the vibration device according to the innovation is used in addition to the vibrations at the same time with heat. Also, in the application of a convertible seat, which is equipped with a so-called Airscarf (Warmluftbeaufschlagung the person sitting in the convertible seat in the neck area), an increase in the "draft risk" and a health impairment of the person reduce because in addition to the warm air in the neck additionally a " Massage "in the back of the person is ensured by the built-in back seat back vibration device.

The sitting or lying device, in particular, if it is designed as a cushion or as a support, may be provided with an interface for data transmission. This interface for data transmission can preferably be designed as a radio interface. So that a person can transmit control or regulation commands to the vibration device via this radio interface, for example, the intensity and / or the dependence of the vibrations starting from an audio signal can be changed via the radio interface in the form of a Bluetooth connection by means of a mobile phone and an app operated thereon be similar to that of an equalizer, so that, for example, certain frequency ranges of the input signal to the vibrating device amplified or attenuated transmitted to the perceptible to the person vibrations. The integration of wireless control and / or power systems allow a compact design and ease of use of the device.

In an alternative embodiment, it is advantageous if the material of the at least one sheet has a density of at least 750 kg / m ³ , preferably a density of at least 950 kg / m ³ , particularly preferably a density of at least 1150 kg / m ³ and an E -Module of a maximum of 2500 MPa, preferably an E-modulus of at most 1600 MPa. As relative material values, a density-to-modulus ratio of 0.35 to 0.95, preferably 0.40 to 0.90, more preferably 0.65 to 0.85, has been found for the sheet Density to modulus ratio is defined by the amounts of SI units of density and modulus.

In a further advantageous embodiment, the actuator, the at least one surface element and a comfort layer form a preassembly assembly, wherein the at least one surface element and the comfort layer at least predominantly lie flat against one another and are connected to each other in a movable manner. This pre-assembly can be easily pre-assembled and handed over to a manufacturer of seating or lying devices and be integrated in the sitting or lying devices. Thus, a manufacturer could provide a seat model in a simple way once with a conventional pad or optionally use the innovation provided with the vibrating pad and thus equip a seat model accordingly. It is particularly advantageous if the preassembly assembly additionally comprises an intermediate comfort layer which, with at least one surface element, lies at least predominantly flat and is connected to each other so as to be movable in some areas. Finally, the preassembled subassembly can additionally additionally comprise an elastic oscillation layer which at least predominantly rests flat against at least the actuator and / or the comfort layer and / or a surface element and is movably connected to one another in regions. The regional mobility can be given by the fact that the surface elements, the comfort layer, the intermediate comfort layer and / or the elastic vibration layer are not connected to each other over the entire surface but only at least partially overlapping at the edges of adhesive strips are fixed together. In other words, by means of the surface element (s), the comfort layer, the intermediate comfort layer and / or the elastic vibration layer, a construction in the manner of a sandwich is achieved, which regions are connected to one another at the edges by means of adhesive strips. This non-full-surface connection of the components has positive effects on the vibration emission behavior of the structure. Furthermore, the flexibility of the vibrator is kept at a high level.

In drawing figure 1 the basic structure of the vibrating device is shown in a simple form in side view. An actor 1 is approximately in the middle of one side of a surface element 3 arranged. The vibration of the actuator 1 becomes directly to the surface element 3 and transferred directly or indirectly by the latter to its contact partner (eg a person). By the opposite to the actuator 1 enlarged surface of the surface element 3 This can be the pointwise radiating vibrations of the actuator 1 spread in a more planar form. The actor 1 is with a control unit 2 operatively connected, which power currents and / or control signals to the actuator 1 can transfer. At the surface element 3 opposite side of the actuator 1 are transmission means 7 . 7 ' arranged, which from there to one from the actor 1 spaced introduction area 8th . 8th' on the surface element 3 extend. These transmission means 7 . 7 ' may be elastic and / or arranged in a prestressed state. The task of the transmission elements 7 . 7 ' it is, in addition to the immediate contact area of the actuator in the illustrated embodiment 1 and surface element 3 Another direct vibration transmitting connection for vibration transmission of actuator 1 to the surface element 3 provide to the emitted vibrations of the surface element 3 reinforced as a surface perceived vibration form. In that also an excitation of the surface element 3 at one of the actuator 1 spaced area through the transmission elements 7 . 7 ' additionally takes place, can a greater homogenization of the vibration radiation through the surface element 3 respectively. Also, the inertia of the surface element 3 to a change of the actor 1 reduced emitted vibration.

Another aspect is in drawing figure 2 can be seen, after which the surface element 3 an external force (here large, down arrow in the upper drawing area) can go along elastic by a deformation. In other words, the surface element 3 - If it is arranged for example on the top of a seat cushion - adapt flexibly and elastically to a pressed body. The actor 1 itself is an at least predominantly rigid element, so that its stiffness by the surface element 3 is mitigated against the adjacent body. The transmission means also work 7 . 7 ' in turn, such that the vibrations emitted selectively by the actuator due to their additional transmission via the transmission means 7 . 7 ' the flat vibration radiation of the surface element 3 is reinforced. For example, the transmission means 7 . 7 ' be configured such that at an increased deformation of the surface element 3 the transmission means 7 . 7 ' subject to a higher voltage and at the same time a higher degree of vibration transmission than in the state of an undeformed or less deformed surface element 3 exhibit. That means that the transmission means 7 . 7 ' one depending on the degree of deformation of the surface element 3 may have variable vibration transmission property. As in particular with an adjoining Body or a reinforced pressing of a body to a vibrating element, the perception of a punctual vibration actuator may be present, provide the transmission means 7 . 7 ' an effective solution to ensure a more even radiation.

In the drawing figures 3 and 4 the vibrating element has a surface element 3 with two sheets 4 . 4 ' on. These two sheets 4 . 4 ' lie in the illustrated exemplary embodiment directly with their longitudinal sides flat against each other and are connected by connecting means 5 . 5 ' connected with each other. The connecting means 5 . 5 ' are designed such that the two sheets 4 . 4 ' at least a relative movement of the two sheets 4 . 4 ' in the direction of their longitudinal axes can run at least to a limited extent. In the illustrated embodiment, the connecting means 5 . 5 ' designed as bands. Furthermore, it is off 3 the height 16 of the surface element 3 as well as the height 14 of the actor 1 shown. These two heights 14 . 16 are as a length perpendicular to the longitudinal extent of the surface element 3 and / or the actor 1 Are defined.

In 4 the vibration device is acted upon by an adjacent body (not shown) or an external force (large arrow), wherein the surface element 3 , or the two sheets 4 . 4 ' yield to the external force and an elastic deformation (bending) takes place. This deformation results at least at the edges of the sheets 4 . 4 ' to a recognizable relative movement, so that the end regions are no longer tightly flush, but creates a type of stepped contour, similar to that of a claimed on bending paperback. Due to the design of the elastic surface element 3 in the form of at least two elastic sheets 4 . 4 ' For example, an increase in elasticity is achieved without unduly restricting the vibration transmission and vibration propagation characteristics.

From the drawing figures 5 and 6 are further alternative or additional embodiments of the connecting means 5 . 5 ' shown. In 5 are the lanyards 5 . 5 ' as edge on the surface element 3 arranged retaining clips or retaining profiles or adhesive tape formed. Also, the retaining clips or the retaining profiles or the adhesive strips by corresponding recesses of at least one surface element 3 , then be arranged at its inner areas (not shown). According to 6 can the connecting agent 5 as hose-like body (band) the sheets 4 . 4 ' surrounded, it can be the connecting means 5 at least one recess for receiving the actuator 1 include. Alternatively, the actor could 1 also from the lanyard 5 be surrounded. All embodiments of the connecting means 5 . 5 ' is to own, that these a relative movement of the held by these sheets 4 . 4 ' allow in at least one translational and / or rotational degree of freedom. In the 5 and 6 For example, the released motion would arise along the space axis perpendicular to it from the plane of the drawing.

Figure drawing 7 shows a bottom view of a vibration device according to 1 , where four transmission means 7 . 7 ' . 7 '' . 7 ''' star shaped by the actor 1 away to the respective introduction areas 8th . 8th' . 8th'' . 8th''' of the surface element 3 extend. The transmission means 7 . 7 ' . 7 '' . 7 ''' can alternatively or additionally also to the edge 12 of the surface element 3 extend (not shown). Furthermore, it can be seen that the actuator 1 central to the main extension area 13 ie in the middle range 6 of the surface element 3 is arranged. The transmission means 7 . 7 ' . 7 '' . 7 ''' are particularly effective if these minimum distances from the actuator 1 exhibit. For example, the introduction area 8th . 8th' . 8th'' . 8th''' a distance 9 from the actor 1 at least a third of the shortest distance 10 of the actor 1 to the outer limit 11 in the main extension plane 13 of the surface element 3 equivalent. The surface element shown here 3 is rectangular and has a maximum length 15 on, the diagonal of the surface element 3 equivalent. In the case of a circular surface element 3 would be the maximum length 15 equal to the diameter of the surface element 3 , Correspondingly, the maximum length would be 15 with any geometry of the surface element 3 defined as the maximum resulting length in the main extension plane 13 of the surface element 3 ,

In 8th are two vibratory devices, each with a surface element 3 and an actor 1 below a reference layer 17 arranged, wherein the surface elements 3 immediately at the reference layer 17 issue. Between the reference layer 17 and a sitting or lying frame 19 can, as in 8th represented, a comfort layer 18 be arranged. This comfort layer 18 For example, it may be a pad, wherein the pad has a correspondingly designed compliance or material recess, at least in the region of the installation location of the vibration devices, so that the arrangement of the vibration devices for the viewer and / or user of the cover layer 17 not or hardly recognizable and / or perceptible. Also, the two vibration devices are through a single, both vibratory devices controlling control unit 2 in operative connection. The control unit 2 is in accordance with the design 8th on the side facing away from the vibration device of the sitting or lying frame 19 arranged and attached to this. Alternatively, the control unit 2 on the, the vibrating device facing side of the sitting or lying frame 19 be arranged and fastened.

Also could be the edition 29 be used as a pillow. The reference layer 17 opposite side of the edition 29 is as a reference 26 educated. The reference situation 26 is in direct contact with the cover layer 17 and forms together with this one, the rest of the structure at least predominantly surrounding shell. In case of a circulation 29 according to 10 can by geometric and / or material design the comfort layer 18 and the intermediate comfort layer 23 have different vibration conduction properties. In particular, with different design of the comfort layer 18 and intermediate comfort layer 23 it is advantageous if the vibration characteristics of the two layers 18 . 23 over the length of the pad 29 are different, thus, by selecting the user-facing side of the edition 29 , a specific vibration characteristic of individual areas of the edition 29 to be provided. In a simple example, an edition could 29 have on a surface in its longitudinal extent a high-vibration region, followed by a low-vibration region and in turn followed by a high-vibration region, wherein for the opposite side of the support 29 Now, by selecting the side facing it, the user can choose whether to perceive the vibrations amplified at the edges or in the central region of the overlay (length) Paragraph with respect to a circulation 29 Explanations regarding a variable vibration characteristic also apply to sitting or lying devices in general.

The surface element 3 on the first page of the actuator 1 has at least one sheet 4 . 4 ' on. The one on the opposite side of the actuator 1 arranged sheet 3 '' has at least one mating surface body 32 on. In the space between the two surface elements 3 . 3 '' is the control unit 2 , the energy store 27 and / or the interface 28 placed, leaving the remaining space between the two surface elements 3 . 3 '' with an elastic vibration layer 31 can be completed. Also, this elastic vibration layer 31 in one embodiment, in one piece and / or material uniformly with the comfort layer 18 be educated. The between the surface elements 3 . 3 '' arranged, non-vibration generating elements (here: control unit 2 , Energy storage 27 as well as interface 28 ) are via damping elements 43 . 43 ' . 44 . 44 ' . 45 . 45 ' with the surface elements 3 . 3 '' connected. This is intended to unwanted vibrations to the control unit 2 , the energy store 27 and / or the interface 28 avoided or at least reduced.

As in the embodiment according to 11 shown, it may be advantageous if the interface 28 , the energy store 27 and / or the control unit 2 to the respective adjacent component a minimum distance 47 . 48 having. This minimum distance 47 . 48 ensures a basic flexibility of the sitting or lying device. This embodiment allows despite providing a control unit 2 , a storage unit 27 and an interface 28 , the flexible property of the sheet 4 not or only slightly affected by these components themselves.

The upper layer forms the intermediate comfort layer 23 , the middle layer forms the elastic vibration layer 31 and the lower layer is through the comfort layer 18 educated. These three layers are preferably surrounded by an envelope surrounding these layers, for example a textile or leather-made covering. The elastic vibration layer 31 can recesses for receiving the actuator 1 and / or the surface elements 3 . 3 ' exhibit. An essential design measure is a minimum distance 49 . 49 ' the surface elements 3 . 3 ' to the cladding (here the reference layer 17 and reference position 26 ). This distance 49 . 49 ' is in the illustrated embodiment by the elastic vibration layer 31 filled up at the side. Alternatively or additionally, at least laterally to the surface elements 3 . 3 ' also at least partially the comfort layer 18 or the intermediate comfort layer 23 extend. It is essential that the one or more surface elements 3 . 3 ' to the perimeter of the sitting or lying device and / or to the cover layer 17 and if necessary to the reference position 26 is / are spaced by an elastic means. As a result, it is possible to ensure that even when the seat or lying device is seated on a rigid body and also when the seat or lying device is trapped or clamped in or against a stiff environment, the surface elements 3 . 3 ' always a minimum freedom of movement (minimum mobility) is ensured for their vibration and consequently the vibration process is hardly or not affected.
