According to the present application, the illustrated bed 1 is arranged in the sensor 12, the sensor for detecting vibration, movement and/or sound wave. In the illustrated embodiment, sensor 12 is fixed to the back part 4 in the area. On the sensor 12 with the bed 1 of the connection of the details of which will be combined with the Figure 3 to Figure 13 is shown in greater detail.

Sensor 12 for example is configured to piezoelectric or electromagnetic component, and the sensor fixed on the bottom plate of the oscillation and a motion-sensitive, namely in this note to the back part 4 of the frame experience oscillation (vibration) or motion-sensitive. This kind of vibration also includes solid acoustic wave, the solid acoustic wave from the bed 1 on human through the rest of the mattress M is back part receiving and transmitting. "Motion" should be particularly understood as a sensor 12 of the low-frequency oscillation and deflection, its frequency in Hertz or sub-Hertz range. For the above purpose is another sensor type is the electromechanical sensor, such as the micromechanical acceleration sensor.

In addition, sensor 12 (air) can be acoustic sensitivity and in this sense as a microphone. Alternatively, in order to measure the air acoustic wave, there can be for example of a capacitance type microphone separate microphone is used as the additional sensor.

Sensor 12 via the sensor cable 13 and evaluation unit 9' connected, the evaluation unit in this is arranged in the control device 9 in. Alternatively, evaluation unit 9' can be connected with the control device 9 to separate their own formed in the casing. In order to transmit the determined physiological parameter, an evaluation unit 9' can then be with the control device 9 is electrically coupled. If necessary, via the sensor cable 13 for the sensor 12 to provide power supply, and by the sensor 12 output signal is transmitted to the evaluation unit 9'. In an alternative embodiment, sensor 12 can be via a wireless connection (for example, radio connection) and evaluation unit 9' coupling. In this case, sensor 12 is provided with its own energy supply device, for example, where necessary in the form of a rechargeable battery of the energy supply device.

Evaluation unit 9' includes for example amplifier and filter unit, they can from the sensor 12 of the signal transmitted in the extrapolations bits for bed 1 of the persons on certain physical function. In particular, an evaluation unit is provided for according to the sensor 12 of the signal to determine the physiological parameter of the person. These parameters such as relates to the function of the heart and circulation function, and include for example heart rate and respiratory frequency. In addition, located in the bed can also confirm whether the person snoring. In addition, also detects the movement of the person. The following combined Figure 2 used for from the sensor 12 signals to confirm the details of the parameters referred to in more detailed elaboration.

The determined parameters is directly or temporarily stored in the evaluation unit 9' in as wireless signal after 15 transmission to the mobile device 14. In particular, the mobile device 14 can be a commercial mobile telephone ("intelligent mobile phone") or flat panel computer and equipped with corresponding software ("APP"), the software can determine the parameters of the time-dependent sleep assessment and preferably carried on the graphical representation. For example, can be the WLAN (wireless local area network) or Bluetooth as a wireless signal 15 of the transmission path.

In addition, in the evaluation unit 9' can be arranged in the measured physiological parameter and the of these parameters is compared to the predetermined limit value. If the determined parameters during sleep stage is directly (i.e. in the evaluation unit 9' in the absence of a longer time phasing out) transmission to the mobile device 14, then alternatively or in addition, can be on the mobile device to carry out such a comparison. When more than or less than the limit value or when the parameters in one or more from the pre-given range to set up the control device 9 or a mobile device 14 outputs the alarm signal. The alarm signal can be visually and/or acoustically directly from the evaluation unit 9' or the control device 9 or a mobile device 14 output. Alternatively or in addition, can be provided with a mobile device 14 via another here not shown a radio transmission link (for example, WLAN, mobile radio network) sends an alarm message. If the display out of the unusual sleep parameter, can in this way notify the other one. Shown in bed 1 or with sensor 12 electric furniture drive device also can be used for clinical monitoring or patient monitoring or for monitoring infants to prevent the infant from sudden death.

In the illustrated embodiment, sensor 12 as the only sensor is disposed in the back part 4 on. In addition, by the positioning of the bed may also be used 1 or bed 1 at different positions on the plurality of sensor 12. In this case, a plurality of different types (type) of the sensor 12 may be positioned on a bed 1 in. Different sensor types are characterized in that they particularly suitable characteristic frequency range. A combination of different sensor types can be allowed to recording and analysis of very wide frequency spectrum.

In this, the corresponding sensor 12 is positioned with respect to it on the ideal position, in this position particularly well applied to the sensor can be for the purposes of detection of the signal. Thus, ideally, for example in the form of a piezoelectric sensor or an acceleration sensor in the form of receiving solid acoustic wave sensor 12 the position of the bed 1 of the back area or middle area, but for example in the form of a microphone receiving air acoustic wave sensor 12 is arranged in the bed 1 rest on the human upper respiratory tract (for example, mouth or nose) in the vicinity.

With the bed is arranged 1 in the evaluation unit 9' or the control device 9 to prevent the sensor cable connection 13 must be laying on a bed 1 external. The sensor 12 is fixed on the bed 1 in or fixed on the bed 1 to ensure that the sensor 12 is always to be accurately positioned and so as to ensure that the sensor 12 of the reliable assessment of the data.

Figure 2 in an attempt to show the sensor 12 of the measuring signal 20 a part of. The shown on the horizontal axis to seconds as the unit time towards t. The vertical axis shown on the arbitrary units of signal amplitude A.

Signal 20 of the signal curve of the part in quiet sleep stage during the movement of the is not observes the human and snore. The human motion performance range for more than shown dozens to hundreds of a factor. Therefore, movement can be easily identified. The snoring and in connection with the vibration or movement can also be shown clearly distinguish from the signal curve, because snoring and in connection with the vibration or movement of the large amplitude of the reflected several times.

In fig. 2 shown in the signal 20 in the curve, can be observed that there is a regular peak 21, the of the peak caused by the beating of the and are then known as the heartbeat peak 21. From the heartbeat peak 21 spacing of which can be the heart rate is determined. The adjacent heartbeat peak 21 of the pulse time interval permitted to indicate the uniformity, the uniformity of the pulse can be sleep depth measurement.

In addition, in fig. 2 can also be seen, heartbeat peak 21 to lower the amplitude of the frequency of the change regularly. This change through the envelope 22 reproducing. The envelope 22 has shown the alternate rising edge 23 and falling edge 24. The envelope 22 associated with the direction of the hair of the breathing. The rising edge 23 said suction stage, while the falling edge 24 said stage of exhaling.

Figure 2 shows how the example from the sensor 12 of the signal can be inferred - cycle parameters of the heart, are here the pulse and respiration. Other sleep parameter (for example, the motion state and the snoring) can be determined in a similar manner.

In order to assess the signal 20, sensor 12 of original signal particularly by means of the low-pass filter filtration. Also can be used with an appropriate angular frequency (Eckfrequenz) band-pass filter. The low-pass filter or a band-pass filter for eliminating interference frequency. Preferably, by means of a digital signal processor (DSP) to realize the processing of the signal.

In addition or alternatively, the sensor 12 may also be used as the monitoring of the correct function of the electric driving device. Operating the adjusting drive device 7, 8 will cause the movable furniture part (for example, back part 4 and/or the leg part 5) mobile. In addition, operating the adjusting drive device 7, 8 will cause these furniture part and the whole furniture vibration, these vibrations also by the sensor 12 detecting. These vibration occurs in the typical frequency within the frequency range. Signal curve reflects the adjusting drive device 7, 8 of the motor movement. 1st typical relevant frequency range is located in the adjusting drive device 7, 8 of the motor of the motor rotational speed range. In this frequency range shows that the motor itself or the driven gear is arranged on the error. Another typical correlation of the frequency in the range corresponding to the ratio of the transmission mechanism according to the integer fraction, its is about 1:30 to 1:50. In this frequency range that downstream of the transmission stages or rolling bearing in error. 3rd typical frequency range of the hinge located within the range of harsh noise, these hinged member is a part of the furniture fittings. The form and in the range of on the one hand use of the actuating device 7, 8 is the typical, on the other hand, form and amplitude to provide about regulating the actuating device 7, 8 the correct function of the and its wear state information.

Regulating the actuating device 7, 8 in one of the plurality of overload can be according to the sensor 12 in the form of signal is identified. Therefore, sensor 12 for example can be used as the anti-pinch protection (Einklemmschutz), wherein the control device 9 in the adjusting drive device 7, 8 one of the overload stop the drive device or to allow its operation in the opposite direction. Regulating the actuating device 7, 8 on the underruns (Unterlast) can also be a clamping of the sign, for example when the release the furniture part (back part 4, the leg part 5) and almost effortless drive the adjusting motor 7, 8 when, that is the main part of the downward sinking below the furniture part of clamping. The adjustment of the load-free operation of the driving device 7, 8 can also be according to the sensor 12 signal to discern.

In Figure 3 and Figure 4 as shown in the example of furniture used for sleeping bed 1 of another embodiment, the sleep furniture with electric furniture drive device, the electric furniture drive device is provided with regulating the actuating device 7, 8 and for detecting vibration, movement and/or sound wave sensor 12. And all other of the same embodiment, the embodiment of the invention, the same reference mark indicates the same as that in the above example with or the same role of the element.

In order to for the sake of clarity, in the Figure 3 and Figure 4 not shown in Figure 1 as shown in the control device 9, an evaluation unit 9', with transmission link 11 a manual operation of the device 10 and the mobile device 14 and with its switching of the wireless signal 15.

In Figure 3 and Figure 4 in, from two different viewing directions respectively to isometric view once again show the bed 1. Bed 1 but also has the belt foot of the bracket, the bracket to form a basic element. It will be understood that, instead of having a separate structure of the feet of the frame shape support, also may be provided with extending to the floor of four side walls of more particular to the box-shaped support.

The basic element supports the support element 2, the support element holds the liner, in particular not shown here of the mattress. Although once again shown of the bed 1 is used for a person's bed, but the bed can also be in the same manner is designed for a plurality of human double bed.

In this, the supporting element 2 does not have the support of the frame, the frame such as the use of lath as the liner or the bottom of the mattress, but has a substantially self-supporting plate. This kind of bed design such as the so-called box-type spring bed in implementation, wherein the mattress than the traditional and comprises a spring element, the spring element in the absence of elastic bottom plate (for example, presentation is the lath) providing sufficient sleeping comfort.

On the other hand, the supporting element 2 is provided with a plurality of component can be adjusted to each other, in particular is not pivotable middle part part 3, with its relative pivot back part 4 and in this is divided into two part of the leg part 5. In this case, the leg part 5 of the 1st part 5' relative to the support element 2 can be pivoted. The leg part 5 of the 2nd part 5 "in the 1st part 5 'of the free lateral side with the 1st part 5' are hingedly connected, and accordingly the two part 5', 5" of the elevation of the connecting line.

In the not along the pivotal middle part part 3 and back part 4 or the leg part 5 of the 1st part 5 'of the connecting line between, and in the leg part 5 of the 1st part 5' with the 2nd part 5" on the connecting line between the hinge section arranged for example in the form of a pivot fitting. As a sport fitting 60 u-shaped framework of screwing in the back part 4 in the form on the force transmission, the frame of the base on the bed 1 in the transverse direction on the back part 4 and the middle part part 3 extend in a region of the connection. The motion fitting 60 assume Figure 1 shown in the actuating device 7 with the back part of the connection between the device 6 function. In this, middle part part 3 with the basic element 2 fixed distance apart.

In fig. 4 in order to oblique upper side isometric oblique view shows 3 of the bed 1. As can be seen in the graph, in this cannot be seen by the sensor 12 in the area of, four rectangular arrangement of the incision 121 surrounds the back part 4 of the part 120, and the back part 4 is separated from the rest of the area. Through the incision 121, the part 120 in acoustics (i.e., in its oscillation capacity) and the rest of the back part 4 decoupling. The sensor 12 is mounted in the decoupling part 120 of the back. Therefore, decoupling of the part 120 in the below also referred to as sensor plate 120. The notch 121 in between the sensor plate 120 of each corner is the retention of only the relatively narrow connecting plate.

Advantages of the invention is characterized in that the decoupling, the sensor board 120 relative to the back part 4 can be oscillation of the system, the system as a solid acoustic wave and air acoustic wave antenna and transmitted to the sensor 12 on. The sensor plate 120 to a certain extent that used for sensor 12 expanded receive membrane. Therefore, can be in the sensor plate 120 is formed on the larger amplitude, the amplitude result in the sensor 12 of the strong signal. The sensor board 120 on the lower side of the back in the area of positioning is advantageous, because usually in this area because of the breathing and heartbeat signal caused by most clearly to be detected.

Therefore, as the antenna of the sensor plate 120 has such a characteristic, that receiving is located by furniture or bed 1 in order to vibration or acoustic wave of the person sending the physiological signal, such as a respiration signal, cardiac signal, the motion signal, the snoring signal, and these signals are supplied to the at least one sensor 12. To this end, the antenna or sensor plate 120 at least can be understood as a signal receiving unit. In addition, the antenna or sensor plate is also configured to signal transmission unit. In order to best receive and/or transmit the signal, the sensor board 120 by with an extremely small damping of a suitable material. In addition, sensor plate 120 of the geometric shape to a certain extent is configured to optimization of the acoustic wave. This selection of material and/or geometry, such that the acoustic wave and/or vibration-free as possible attenuation guide and transmitted to the respective sensor 12. Of the material used is made of solid wood material and wood fiber material.

In Figure 7 and Figure 8 in, with the Figure 4 and Figure 5 in the same manner as the reproduction of the sleep and rely on the furniture for the example of the bed 1 and the other two embodiments. In these two embodiments, and is not a sensor plate 120 is disposed in the middle of the back part 4 at the lower one-third, but two adjacent positioning of the sensor plate 120 are respectively provided in the back part 4 of the lower-left half and right half in. This kind of arrangement for detecting sleeping as independently as possible noise and vibration or movement, and thus the detection side by side lying on the bed 1 on two of the physiological parameter of the person. In fig. 7 in the embodiment of the, once again through the incision 121 separated, but not completely separate back part 4 region is configured to sensor plate 120. In these sensor plate 120 in each of the below are mounted on all single sensor 12. In the Figure 8 embodiment, similar to the Figure 5 example, sensor plate 120 through the retaining element 123 is disposed in the peripheral notch 122 in. Here also are respectively in each of the sensor plate 120 is provided with the single sensor 12. Shown with two sensor plate 120 and two sensor 12 can also be in the arrangement of the bed 1 in use, wherein a single people how to is located in the bed 1 on, each sensor 12 of sensor signals are averaged, or take into account the sensor 12 in the respective one of the stronger signal.

In fig. 9 to fig. 12 in, shown as a according to the present invention rely on the furniture of sleep or for example bed 1 of the embodiment of the other four.

In these embodiments, the sensor plate 120 or these sensor plate 120 is not disposed in the back part 4 in, but is disposed in the middle part part 3 in. Experiments show that, in the in the sleep of the people in the lower back or buttocks of the positioned therein middle part part 3 in the area is also very suitable for catching the sleep noise, motion and vibration of, these sleep noise, motion and vibration allows to infer the physiological parameter. In this case, middle part part 3 can be relative to the bed 1 of the frame is fixedly arranged. In the so-called "wall (wall hugger)" in the bed, when the back part 4 when the deflection, middle part part 3 in the bed 1 on the end of the direction of the head of the mobile, in order to prevent the back part 4 and bed by its head on the end of the clearance between the wall. Further alternatively, also can be envisaged deflection slightly lower middle part part 3.

A sensor plate 120 or a plurality of sensor plate 120 in the middle part part 3 on the advantages of the arrangement of, based on lying on the bed 1 of the persons on the gravity load independent of to back part 4 or the leg part 5 of the adjusting is basically constant. Mechanical boundary conditions affect the sensor 12 or the sensor plate 120 of decoupling. The boundary condition is constant, can be more clearly to the sensor 12 of the assessment of the measurement signal.

In the illustrated embodiment, similar to the Figure 4 and Figure 5, is provided with the respectively associated with the sensor 12 in the middle of the sensor plate 120, or respectively arranged in Figure 11 and Figure 12 in the example of the 2 adjacent arrangement of the sensor plate. Once again can use different type of sensor plate 120 of decoupling, that is according to fig. 9 and fig. 11 embodiment of the introduction of slit type not connected to each other in the cut-out 121, or in Figure 10 and Figure 12 in the embodiment of the circumferential cut into 122 and the use of the holding member 123.

In its orientation illustrated in the example of cannot be changed and not with adjusting motor 7, 8 in the middle part of one of the coupling parts 3 in, can be used for signal amplification of the other method. This in fig. 13 shown in. Because the middle part part 3 not with the motion fitting coupling and with the back part 4 or the leg part 5' and 5" compared with the small, therefore the embodiment of the invention the whole middle part part 3 is used as the sensor plate 120.

In order to also in this case the antenna effect, middle part part 3 is placed in the elastic element 124 on the (buffer), the elastic element such as rubber or silicon resin elastic and soft material or the soft plastics, and allow the middle part part 3 relative to the support frame 2 oscillation. In fig. 13 shown in the middle of the lift part 3, to show the elastic element 124 and its arrangement.

In all previously shown in the embodiment of the, as low as possible loss to the vibration (especially solid acoustic wave) from the decoupling part 120 or from the sensor plate 120 transmitted to the sensor 12 is important. Sensor 12 and decoupling part 120 or the sensor plate 120 are respectively used for transmitting the acoustic wave and/or solid acoustic wave and/or vibration of the connection.

Preferably, are fixedly connected. Alternatively, the connection is that the material cooperates. In addition, preferably, the connection is not allows the sensor 12 and the sensor plate 120 relative movement between. Advantageously, in this way the acoustic wave or vibration to the sensor 12 on the attenuation of the transmission of very small or close to zero. For example, by bonding to the realization of the sensor 12 in the sensor plate 120 on the connection is suitable. May is a multi-component liquid adhesive or can replace the thin film adhesive can be used as the adhesive. Thin film adhesive for example can be a double-sided adhesive tape coated with an adhesive film. In addition, the connection may also include a primer and the like, the sensor plate 120 and/or the sensor 12 in the bonding process is set before the primer.

According to another embodiment of the connection, the connection is a material-fit connection, so that the sensor 12 is formed with the sensor plate cannot be separated from the unit. This material cooperates or pressing unit can be realized by casting. Ideally, the sensor 12 is disposed in the sensor plate 120 in the groove and by means of the casting material with its cast together. Alternatively, sensor 12 can be described by means of the casting material of the casting in the sensor board 120 or on the surface of the normal injection in the sensor plate 120 on the surface.

According to another embodiment of the connection, the connection is provided with a force. In this case, sensor 12 by means of a continuing force applied to the sensor plate 120 in the direction of the to be fixed. In this case, sensor 12 can directly contact the sensor plate 120. However, preferably, is arranged to receive the sensor 12 and the sensor of the at least one electrical connection of the sensor housing. Ideally, the sensor housing can be connected with the sensor plate 120 joint, so that even in the bonding process after the end of the sensor 12 itself with the sensor plate to form a fixed connection. In addition, there can also be the aforesaid connecting combined. Increase the sensor housing in principle is advantageous, because the sensor housing to protect the sensor 12 and the cable stress relief can be implemented. Therefore, alternatively, can be protective covers covering the housing with the sensor plate 120 and firmly glued to the sensor 12 and has a sensor 12 of the stress relief of the connecting cable. Similarly, the corresponding housing such as a through bolt and the sensor plate 120 firmly connected.

In Figure 14 and Figure 15 in, respectively in order to isometric view showing a sensor of the appropriate sensor housing 125 of the example. The sensor 12 for example can be used for Figure 3 to Figure 12 in the embodiment shown in, and may also be in fig. 3 in the example of to see.

The sensor housing 125 includes a dome-like shell upper part, the actual acoustic wave or oscillation receiver is arranged in the housing part. Preferably has bending protective cable sleeve 130 for through sensor cable 13. A dome-like housing component are arranged in the center of the mounting plate 126 on. The mounting plate 126 has such as used for screw mounting of the fastening hole 127.

Such as in fig. 15 it can be seen that, in the towards the furniture part (for example, back part 4) of the mounting plate 126 on the underside of the arrangement of the lug 128, sensor 12 in the mounted flat on the surface of the projection abuts against the through on this surface. Therefore, in particular, the oscillating transmission of the projection 128 in the area on the. Preferably, the sensor housing 125 internal, has its oscillation of sensitive areas of the actual acoustic wave or oscillation receiver is disposed in the lug 128 above. For this reason, if needed, the lug 128 can continue to inwardly extending, so as to realize the sound wave or oscillation of the receiver to the oscillation-sensitive part of the direct transmission. In this way, the solid acoustic wave transmission as directly as possible to the acoustic wave or oscillation receiver.

In addition, the housing 121 for electronic device still exist in sufficient installation space, so that the sensor signal of the signal processing can be directly in the sensor housing 121 in the. The signal processing can include from the acoustic wave or oscillation from the receiver of the signal of the amplifying and/or filtering. In the sensor cable 13 may be provided for in the sensor housing 121 in the assess the electronic device of the corresponding power supply wire. In addition to the for signal pre-processing of the outside of the electronic device, the above assessment unit 9' also may be placed directly in the sensor housing 121 in.

According to another embodiment, the sensor 12 in the sensor plate 120 of during the manufacturing process is introduced into the sensor plate. In the is formed of plastic of the sensor plate 120 in, sensor 12 of the sensor plate 120 in manufacture of casting to the sensor plate. By the fiber - wood material forming the sensor plate 120 in, sensor 12 of the sensor plate 120 in the manufacturing process is introduced into the sensor plate. By the laminated wood material forming the sensor plate 120 in, sensor 12 of the sensor plate 120 in the manufacturing process of bonded or laminated to the sensor plate.

Alternatively, also can use the metal sensor plate 120 or is made of plastic material of the sensor plate 120. Figure 16 shows in this exemplified in the sleep or rely on the furniture plate-like element (for example, the aforesaid embodiment of the back part 4) are respectively in the sensor plate 120 the two upper sensor 12 of this kind of arrangement.

In the illustrated embodiment, in the back part 4 is introduced into the flat groove 40, in these grooves are placed in the here also basically is constructed the flat elastic element 124. The elastic element 124 for example can be made of flexible rubber or sponge rubber or silicone material. The resilient member has a protruding upward from the peripheral edge, the peripheral edge forming and inserting the sensor plate 120 of the . Preferably, the sensor plate 120 is made of a hard material such as aluminum, or is made of hard plastic or also are made of steel. Preferably, the elastic element 124 on one side and back part 4 of the connection and on the other side with the sensor plate 120 are connected through the bonded to realize. Also preferably, the piezoelectric element of the sensor in the form of 12 bonded on the way to the sensor plate 120 on. The sensor 12 on the way of the bonding preferably placed protective cover 129. The protective cover 129 at the same time used for fixing the sensor cable 13, the sensor cable here is guided through the back part 4 of the surface. Alternatively, sensor cable 13 can also be guided through the hole to the back part 4 of the other side. The hole can be directly adjacent to the sensor plate 120 extends through the back part 4 or in the sensor plate 120 in the region of the guide through the sensor plate, the elastic element 124 and back part 4.

Figure 17 shows the arrangement of the combination state. As in the previously-described embodiment as in, the sensor board 120 used as a supporting element 2 of the decoupling part of the acoustic wave, the portion of the special absorbing solid acoustic wave and transmit it to the corresponding sensor 12. In fig. 17 in, sensor 12 itself is hidden in the protection cover 129 and below can not be seen.

With the thus far different from the illustrated embodiment, in Figure 16 and Figure 17 in the example of, the sensor plate 120 towards the placing of the mattress. The elastic element 124 so that the sensor 12 with for example via the bed 1 of the bracket of the transmission of the sound wave interference effects of the pace of decoupling. In addition, they will by transmission of the mattress in the bed 1 of the person resting on the solid acoustic wave combined and in that sense serves as the sensor 12 of the antenna element.

In the illustrated arrangement, the sensor 12 is arranged in the middle of the sensor plate 120 on. However, can also be eccentric positioning. In addition, can also imagine sensor 12 is disposed in the sensor plate 120 of the outside of the main surface, for example disposed projecting out from the main sensor plate 120 of the tongue piece (Zunge) or tab (Lasche) on. This can be at least the selected frequency within the frequency range further enhance the sensor signal.

In order to protect this arrangement, in addition to the protection cover 129 can also be set up to use the outside protective material covering the whole of the back part 4. In the box-type spring in the bed, is basically set up the plate-shaped support element of this covering.
