    专利说明:

    The invention relates to a support device for reclining or seating devices with an at least partially fixed frame and with intertwined, strained straps that define a support surface and which are accessible from both the upper support side and from the opposite bottom.
    Such devices are used in particular for beds or loungers where their robustness and their proven, for example, compared to pure metal or mat constructions higher comfort.
    The US 3,742,527 describes a hospital bed with a divided into mutually pivotable sub-segments mattress pad with strained in the longitudinal and transverse straps, which are accessible from the bottom. The moving parts of the frame of the mattress pad are adjustable by means of pneumatic drives. Due to the intransigence of the mattress pad for the purpose of lying comfort the use of a softer mattress between support and user is necessary, which, however, greatly reduces inter alia the air permeability from the bottom to the support surface and penetration for a massage is practically prevented.
    CN 201067225 Y discloses a mattress whose core is formed by a network of intertwined palm ropes fixedly arranged in a perforated rectangular wooden frame; The mattress is surrounded by a moisture-proof nylon layer to prevent deformation of the core.
    The CN 2779994 Y shows a mattress with a solid wooden frame, which is covered with intertwined straps, the tension of the straps is only globally adjustable for the entire support surface.
    In none of these known support devices can the tension of the straps be localized, i. For individual straps, be readjusted, which is why disadvantageously no adaptation of the support surface to the locally modified compliance or to the locally required different voltages can be made.
    It is therefore an object of the invention to provide a support device of the type mentioned, in which the flexibility of the support surface is locally adjustable, so that an improved comfort in use is achieved. In particular, the hardness of the support surface should also be adjustable so that the use of a mattress is superfluous, which in comparison to conventional mattresses high air permeability of the belt network can benefit the user directly. In addition, the lowest possible noise in the movement of the straps should be given.
    The support device according to the invention of the type mentioned solves this problem by at least some of the straps are connected by means of separately adjustable tensioning devices with the frame, so that the bias of the straps locally adjustable and the hardness of the support surface is locally adjustable.
    A low noise is achieved by a very good lubricity of the belt surface.
    In the present support device, therefore, a local slackening of the belt tension can be compensated if the decrease due to strong local loads of the support surface concerns only a portion of the straps, without having to increase the tension of the other straps also. Likewise, the "hardness " the support surface are partially adapted to the physical conditions of the current user, for example, in the case of a couch in the hip, knee, heel and shoulder area a lower hardness is set. When changing the user or when changing needs, the settings can be changed at any time without much effort, and the support or support characteristic can be adjusted again. Last but not least, due to their arrangement between straps and frames, the tensioning devices can also anticipate and / or correct changes in the frame.
    [0010] The invention can be applied to beds / beds with particular advantage, but is of course also in other persons, persons supporting facilities, such as armchairs or similar seating furniture, to motor vehicle, train -, bus or aircraft seats used, and indeed for their backrests.
    In particular, for the use of several similar reclining or seating devices and for easy replacement of parts of the support device according to the invention, it is advantageous if the frame forms a first module with the belts, on the underside of which a second module forming treatment device is arranged , which in turn is arranged on a third module formed by a substructure. Thus, for example, the first and generally lightest module may be separated from the rest of the support for cleaning purposes, thereby facilitating transportation and cleaning. In addition, the treatment device, so the second module can be replaced as needed, especially if different treatment facilities are available with different treatment functions, or for example for easy replacement of defective treatment facilities while maintaining the first and third module and the settings made there.
    In an efficient and relatively inexpensive variant of the device according to the invention, the straps connected to a tensioning device are connected at their opposite end of the clamping device fixed to the frame. This requires only a one-sided adjustment of the belt pretension, but this is hardly disadvantageous, for example, in areas with relatively high biases, since the game allowed by the tensioning device is low there anyway.
    If the straps are connected at both ends with a tensioning device, which preferably have the same spring stiffness, a displacement of the straps in the central region of the support, thus against a loaded point, at least partially avoided, since the straps in the direction of both ends give in. In addition, in this case, a total of greater flexibility 4/42 4 R 618 9 8 or a wider range of possible bias settings can be achieved with otherwise identical fixtures.
    The finest local Einsteilbarkeit the Gurtvorspannung is achieved when a single belt is connected to each jig. In particular, in this case, approximately flowing transitions between areas of the support surface can be adjusted with higher and lower pretension or hardness by adjusting the straps therebetween with correspondingly stepped pretensions. For example, if more than one strap is connected to a tensioning device, the number of straps connected to a tensioning device may be a maximum of ten straps of width less than 30 mm or a maximum of five straps of width about 50 mm.
    It is also advantageous if the tensioning devices have a sliding or rolling guide of the straps, as thus, for example, grinding noise of the support can be avoided and it can be ensured that the flexibility of the straps is oriented exclusively along the Gurtverlaufs. An orthogonal to Gurtverlauf the tensioning device, which could have their damage or distortion of the hardness adjustment for the support surface result, can be avoided by the between support surface and clamping device operatively arranged sliding or rolling guide of the straps.
    In addition, to keep an unpleasant - because not formed by straps - edge region of the support surface as small as possible, it is advantageous if the sliding or rolling guide the straps towards the bottom, preferably at an angle of about 90 °, deflects. Thus, the clamping devices can be arranged substantially below the support surface and space-saving on or in the frame.
    In particular, when the straps are substantially, i. In the context of the usual in the given use forces are inelastic, it is advantageous if the tensioning devices have a suspension, wherein the force exerted by the respective spring Fe- 5/42 5 R61898 substantially corresponds to the bias of the associated belt. Appropriately, therefore, the adjustment of the bias voltage can be made via the variation of the spring deflection. The suspension can be a resilient element, for example a helical spring, a band spring, a suspension via elastic materials (for example rubber, silicone) or a gas pressure spring, whereby particular attention should be paid to the lowest possible noise development.
    In connection with the suspension, it is advantageous if the maximum stroke of the suspension or the maximum spring deflection, preferably at a value of ^ 10 cm is limited. Thus, typically excessive temporary loading - for example, when supporting with the elbow or getting up - an excessive or undesirably deep local sinking or yielding of the support surface can be avoided, so that the activity in question is not or as little as possible difficult or hindered.
    A particularly rapid adjustment of the support device is possible when the clamping devices comprise a drive for adjusting the bias. The drive can generally replace a manual setting and, for example, allows those users to adjust the bias to their own needs, which would otherwise rely on outside help.
    If the moment applied by the drive sufficient to adjust the bias during use of the support device, for example, 1.5 Nm, depending on or adaptable to the weight class of the user and the belt width, per belt is, the device for and not relieved or left during the adjustment of the hardness. This is especially with frequent new hires and with movement-restricted users (certain illness cases) the
    Support device of advantage, which can thereby particularly benefit from the advantages of the device.
    A preferred variant of the connection between belt and 6/42 6 R 618 9 8th
    Drive is that the drive is connected via a spindle with the belt. The spindle provides a high power transmission from a rotating to a translatory movement, which for example, the use of relatively weak compared to the bias electric motors, e.g. Stepper motors enabled. At the same time due to the translation, a high precision of the bias adjustment can be achieved.
    If both a suspension and a drive are used, it has been found to be advantageous if the drive is operatively disposed between the suspension and the belt. In particular, with this arrangement, the drive is mounted damped relative to the frame, whereby any vibrations caused by the drive are decoupled from the frame and thus noise is reduced. Apart from that, the connection between the drive and the belt is easier if there is no suspension between them, which could disadvantageously also absorb a torque.
    A particularly comfortable adjustment of the support device can be achieved in that the drives of the tensioning devices are controlled separately or controllable, wherein a locally adjustable bias of the straps according to a bias voltage profile, e.g. automatically, is adjustable. In conjunction with a corresponding control, different bias profiles can thus be set depending on the person using and / or currently preferred positioning, body position or therapeutic needs.
    Long-term changes or certain time-dependent functions can further be realized in that the drives of the clamping devices are time-controlled and the bias of the straps is automatically changed time-dependent. Usage examples illustrating the benefit of such timed changes are the continuous redistribution of stressed body sites of patients or the adaptation to the sleep phase of a user. By means of a corresponding control program, special medical effects can also be achieved, such as systematically from below (condal) or upward migrating (direction of the heart) pressure (alternating pressure) or support in the removal of tissue fluid (edema).
    Especially for observation, but also for the automated determination of the bias setting, it is helpful if the tensioning devices comprise a force sensor for determining the contact pressure, wherein the force sensor is preferably fixedly connected to the belt. The evaluation of the values transmitted by the force sensor allows conclusions about the position, the weight and possible pressure points and allows the automatic or semi-automatic adjustment of the preload profile to the current use. When the force sensor is directly connected to the belt, the force can be directly detected with the highest accuracy and dynamics. For lower demands, the respective force can also be calculated indirectly via the measured drive power of the drive.
    A particularly reliable adjustment of the prestressing profiles is given when the drives of the tensioning devices are controlled as a function of the contact pressure determined by the force sensor. Under these circumstances, for example, it is automatically possible to react to changes in the body position of the user.
    In order to ensure a high level of safety for the user even when loading individual straps, the straps and / or the tensioning devices should have a tensile strength by at least a factor of 3 higher than the required Gurtvorspannung (depending on the weight class of the user).
    In addition to the excellent air permeability and the associated natural temperature of the support surface allows the support device according to the invention due to the accessibility from the bottom and the small thickness and compressibility of the support surface forming straps the use of a bottom, i. as a treatment device according to the above-described module structure, arranged therapy device or a therapy device, wherein the therapy device preferably as massage device interchangeable and / or 8/42 8 R61898 automatically switchable massage heads and / or treatment heads (local cooling or heating) includes.
    A tailored to the anatomical conditions massage can be made possible by the massaging device by means of touch-sensitive scanning and / or non-contact, in particular capacitive, measurement performs an automatic orientation of the user located on the support surface. Thus, the body sites or regions to be massaged can be determined independently of absolute positioning. If appropriate, the values determined by the force sensors can also be used for coarse orientation or initialization.
    Since the temperature at the bearing surface for the comfort of the support device is a central parameter, can advantageously as needed at the top or bottom of the bed, a heater, such as an electric heater or infrared radiator, and / or cooling, for example a Fan, a cooling head or a Temperierkreislauf with a tempering, be arranged, whereby depending on the ambient and body temperature a pleasant temperature of the support surface can be made. In this context, it is also desirable to introduce certain temperature profiles on the support surface.
    For use in the care or hospital sector, it is desirable if the straps are made of a heat-, UV- and moisture-resistant material and are thermally and chemically disinfectable. Such an easy-care and, for example, easy to disinfect with a hot water high pressure cleaner device can be offered without restriction even under hygienically demanding conditions, since thus no drawn between the support surface and user dense protective layer is necessary. Such protective layers, as are common and necessary for example for the protection of mattresses, would severely impair the air and temperature permeability of the device as well as the therapy / massage options. In order to largely avoid the development of noise as well as any undesired displacements when adjusting the tensioning devices, it is advantageous if the straps have a low-friction or lubricious surface, wherein the frictional resistance between the straps is so low that it relative to the bias voltage is negligible, and noise during the displacement of the straps are minimized.
    When used for immovable or difficult umzubettende patient in the hospital and / or care sector, it is also useful if the support surface has a mattress comparable or lower absorption capacity for X-rays, as thus various diagnostic procedures can be performed directly on the support device , which is favored in particular by the accessibility of the support surface from the bottom.
    The advantages mentioned hitherto can be achieved, for example, if the straps consist essentially of polyester braiding, rayon, Goretex or aramid ribbons, alternatively of hybrid weave fabrics (for example reinforced with carbon fibers).
    To increase the lubricity, the straps may additionally have a coating, in particular a Teflon coating.
    When the frame is divided longitudinally in preferably at least two, in particular four, interconnected by joints sub-segments, wherein the hinge axes are arranged transversely to the longitudinal direction of the frame, the support device can support a variety of postures. The sub-segments can be aligned in parallel or mechanically or via auxiliary drives, for example, commonly used for hospital beds, industrially available linear actuators, so-called lifting columns are adjusted in the angular position. For example, depending on the arrangement of the subsegments, the same device can be used either as a lying or sitting device, for lifting the head part or in the knee area.
    To support the adjustment of the angular position of the sub-segments can be connected to the frame drives that cause a certain setting or support a movement of the sub-segments. The control of the position of the individual segments of the support and the specification of various therapeutic massage programs or cooling or heating measures via an operating computer (Human Machine Interface, short HMI) or remotely controlled. There are various levels of security for the parameter change or input. Therapists and physicians have access to the highest level of security with a special password, with the possibility to set all available parameters and programs for the user. Nursing staff has access to a reduced parameter area, also protected by a special password, or can schedule predefined therapeutic treatment programs. Functions unlocked by higher security levels can be activated by the user at any time without a password. When using a bed for several users, user-specific characteristics, for example the stiffness profile of the straps, can be stored and retrieved in the HMI.
    Especially in public facilities, such as hospitals, nursing homes or hotels, when a support device is used in different places and for different users, it is advantageous if the base braked rollers for moving the device and a preferably electrical, alternatively hydraulic or pneumatic auxiliary drive for lifting and lowering or tilting of the support device, in particular individual sub-segments of the frame has.
    Also, especially when using a plurality of inventive support devices in a single room, it is advantageous if the noise or noise is reduced to a minimum in all uses. Particular attention should be paid to the rolling guides, the suspensions and the drives, but also the friction between the straps should be kept as low as possible. When using a massage device or a cooling or heating device, a low noise development is also desirable here and can be achieved by suitable drives, such as direct drives with a toothed belt.
    The invention will be explained below with reference to particularly preferred embodiments, to which it should not be limited, and with reference to the drawings. In detail in the drawing:

    In Fig. 1, a support device 1 for a reclining device, in particular a bed, is shown in a schematic plan view. The support device 1 has a rectangular in plan view frame 2. In frame 2 straps 4 are stretched between one another on opposite frame elements 3a, 3b. The straps 4 extend in two groups in parallel either in the longitudinal direction of the frame 2 or transversely thereto and are arranged at equal intervals. The distance, i. the free space 9 between the belts 4 should not exceed 10 mm in order to prevent breakage, for example with the elbow during support. In a preferred embodiment, the belt spacing is about 5 mm. In order to avoid slippage of the straps 4 transversely to the direction of tension, the straps 4 are intertwined, wherein, for example, a longitudinal belt 5 is arranged alternately above and below successive transverse straps 6. Depending on the belt width selected, however, alternative braiding combinations (for example two longitudinal and / or transverse belts) may also be selected. The width of parallel straps 4 is substantially constant, in the example shown, the longitudinal straps 5 are narrower than the cross straps 6. A belt width of at least 5 mm, preferably between 30 and 200 mm, in particular 50 mm, provides a suitable compromise between local Einsteilbarkeit ( Comfort), strength and economy. Narrower straps 4 allow a finer adjustment of local stiffness and thus greater comfort through a more even pressure distribution. They are particularly advantageous in areas of high contact pressures (sacral, knee, shoulder and heel area). Wider straps 4 require less technical and thus financial expense. At both ends, the straps 4 are connected to the frame elements 3a, 3b, wherein the connection is made at least at one end and at least at one transverse side of the frame 2 by means of tensioning devices 7 (see Fig. 4). The area enclosed by the frame 2 is covered by the belt mesh, so that the straps 4 form a bearing surface 8. The remaining between the straps rectangular openings 9 in the support surface 8 have the distances between the straps 4 corresponding edge lengths and determine a relatively high air permeability of the device. In addition, perforations 4 '(see Fig. 2) (perforated pattern) may be provided in the belts 4 in order to further improve the ventilation of the support surface 8 from the underside.
    As for the material and the structure of the straps 4, they must not only meet the mechanical requirements, such as a certain tensile strength, but often meet additional requirements in terms of hygiene and cleaning options. In particular, it is desirable that - as with ordinary mattresses or foam inserts - with plastic inserts must be worked, which would greatly reduce the comfort. If the straps 4, for example, from polyester braid, artificial silk, Goretex or aramid ribbons, alternatively from hybrid fabrics (eg reinforced with carbon fibers, without or with coating to increase the lubricity, for example with Teflon), the support surface 8 can directly with a High-pressure cleaner cleaned and prepared according to the hygienic requirements for use, in particular disinfected, be.
    Fig. 2 shows two clamping devices 7 according to the detail II in Fig. 1, wherein it can be seen that the frame member 3a and 3b of two parallel longitudinal struts 10, 10 'and interposed transversely arranged roller supports 11 is constructed. The belt width and belt spacing are not shown to scale, but would preferably be 50 mm and 5 mm respectively. In the roller supports 11 roller axles 12 are arranged parallel to the longitudinal struts 10, which serve as a support of the rollers 13 forming an unwinding guide. The distance between the longitudinal struts 10, 10 'is greater than the diameter of the rollers 13, so that the distance between the roller 13 and the outer longitudinal strut 10 at least equal to the thickness of the belt 4. Preferably, the height of the inside longitudinal strut 10 'is selected so that the apex 14 of the roller 13 projects beyond the longitudinal strut 10' on the inside, so that the belt 4, without touching it or on it to grind over it is curious. Alternatively, an inner longitudinal strut 10 'can also be completely dispensed with (cf., Fig. 4), wherein the roller axes 12 and thus the rollers 13 are then supported, for example, by cantilevered brackets 15 as roller supports 11.
    As shown in Fig. 3A, the straps 4 may be connected only at one end 16 with a tensioning device 7. The tensioning device 7 opposite end 17 is then for example firmly connected to the frame 2. In this case, the tensioning devices 7 of all straps 4 can be arranged on a frame element 3a, 3b, or the tensioning devices 7 of successive parallel straps 4 are arranged alternately once on one and then on the opposite frame element 3. The lowest production cost is achieved when only two mutually perpendicular frame members 3 (a transverse element and a longitudinal element) all the clamping devices 7 are arranged.
    However, a greater comfort offer on both sides connected to the straps 4 tensioning devices 7, as shown in Fig. 3B. Due to the lower friction between the straps 4, this variant also allows a reduction in the noise during use.
    In Fig. 4, the structure of a preferred embodiment of a clamping device 7 is shown in detail. As already explained in connection with FIG. 2, the belt 4 is guided via a rolling guide 18 with a roller 13. As can be seen in detail here, the rolling guide 18 leads the belt 4, starting from a horizontal bearing surface 8 along a quarter segment of the roller 13 by 90 ° in a vertical. The roller 13 of the rolling guide 18 is rotatably mounted about a roller shaft 12, wherein the roller shaft 12 is disposed in the provided as a roller support 15/42 15 R61898 11 console 15, which in turn is connected to the outside frame member 10. The vertically downwardly facing strap end 19 is disposed in a clamp 20 and held. The clamp 20 is connected via a bearing 21 to a force sensor 22, e.g. connected to a DMS element. At the bearing 21 opposite side of the force sensor 22, this is coupled to a fine thread 23 having a threaded spindle 24 and secured against rotation. The force sensor 22 thus measures the train directly between the spindle 24 and the belt 4. The fine thread 23 having spindle 24 is connected to the shaft 25 of a drive 26, in particular an electric motor 27. The drive 26 itself is finally connected via a suspension 28 to the frame 2 of the support device. The suspension 28 is formed by a compression spring 29 and / or an additional resilient filler 30, such as rubber or silicone, and is compressed by the Gurtvorspannung. In the example shown, the belt tension is set by the adjustable by means of the drive 26 position of the shaft 25 in the threaded spindle 24. The support of the suspension 28 via the horizontal engagement surface 32 which is fixedly connected to the frame member 10. As an alternative embodiment, it would also be possible to choose a common drive for a frame side for a frame element 3a or 3b, wherein the adjustment of the respective belt pretension takes place by a targeted coupling of the drive (for example displaceable gearwheel) to the threaded spindle 24.
    The maximum stroke of the suspension 28 is defined by the maximum compressibility of the spring elements 29 and 30, respectively. In -praktisch impossible - complete compression of the suspension 28, the drive 26 would give a maximum up to the plant to the attack surface 32 upwards. The setting of the mechanical Gurtvorspannung done via the supply line 33 of the drive 26, wherein a corresponding polarized current or 16/42 16 R61898
    Stepper motor causes a pulse train over a certain period of the desired spindle rotation in one or the other direction. If the belt 4 does not act as suspension itself, the translational movement caused by the spindle 24 results in a compression or decompression of the spring 29 and / or the spring filler 30 and thereby an increase or decrease of the bias of the belt 4. Because of the deflection of the Straps 4 acts without stress on the support surface 8, the force corresponding to the bias not only horizontally between the opposite frame members 3a and 3b, but also vertically between the rolling guide 18 and the engagement surface 32 of the suspension 28th
    The stroke of the threaded spindle 24 is suitably at most the same size as the maximum stroke of the suspension 28, wherein the length of the vertical Gurtabschnitts must be selected so that it does not lead to a collision of the Gurtklemmung 20 and the under load, especially at low bias voltages Roll 13 is coming.
    The illustrated in Fig. 4, substantially unyielding connection between the drive 26 and force sensor 22, in particular without intermediate suspension, achieved an immediate and trouble-free mechanical feedback from the drive 26 to the force sensor 22 in a control loop 34, such as in FIG. 5 shown. Here, control loops 34 for three independent tensioners 7 are shown schematically, which relate their respective desired values, to which the belt pretension is regulated, from a common preload profile. The individual control loops 34 have not only the force measurements or force sensors 22 but also regulators 35 and actuators 36 (corresponding to the drives 26). In practice, a selectable bias voltage profile is preset via a central, program-specific setpoint specification for the controllers with the coupling 37 from the operator 17 (computer) 43. The controllers 35 provide the required drive signal for the actuators 36 based on the actual value detection by the force measurement 22 and / or the current measurement (Ui, U3, Uk, etc.).
    A - in addition to the comfort gain - the central advantage of the present support device 1 is the accessibility of the support surface 8 also from the bottom and thereby enabled application scenarios. The versatility of possible uses of the module structure shown in FIGS. 6A and 6B example of the support device 1 is particularly helpful. Even if only a massage device 38 is shown here as a treatment device 39, it is understandable to the person skilled in the art that between the first module 40 (shown only schematically in FIG. 6, without straps) with the support surface 8 and the third module 41, which has a universal base forms, a variety of treatment facilities 39 can be used. In particular, the use of a "heat tool" should be mentioned here. or a "cooling tool" (See Fig. 6D), for example, an infrared radiator or an electrical resistance heater or a pre-cooled cold head - optionally used instead of a massage head 42 - in the massage device 38 for local heating or cooling of the support surface 8 or pointed by body regions of the user. For global warming or cooling of the bearing surface 8, the third module 41, for example, at the foot, a heater (eg electric heater or infrared radiator) and / or a cooling unit 67 (eg with Peltier elements or special cooling media and cooling circuits) including ventilation with variable speed ,
    Due to the small thickness of the support or the straps 4, a good penetration can be achieved when used with a massage device 38, which favors in particular local treatments. Thus, massage movements for the neck, back and leg area such as effleurage, walking, tapping and vibrating, controlled according to therapeutic principles, can be performed from the underside of the support device 1. To carry out the various techniques, the massage device 38 has massage heads 42 (see Fig. 6C), which can be moved, for example, each with six degrees of freedom (three axes of rotation and three translation directions). In addition, various massage heads 42 may be provided which are manually or automatically selected and used. Possible applications are, for example, lymphatic drainage, (micro) stimulation to prevent damage to health due to long immobilization (eg decubitus ulcer) and loss of self-esteem for individual body parts (especially shoulder, sacral region and heels), mental relaxation, strengthening the immune system, improving microcirculation and the prevention of pressure ulcers. The automated implementation of appropriate therapies not only provides relief for the nursing staff, but also promotes a quick recovery and thus shorter stay, especially in hospitals. To prepare the respective massage program, the current position of the person to be massaged at the beginning but also during the massage by a surface, very gentle scanning, according to the Effleurage, with the massage device 38 or non-contact (eg with inductive, optical or infrared, preferably capacitive Sensors) determined.
    In Fig. 6C, a massage head 42 is shown in detail. The massage head 42 is connected to the massage device 38 (see Fig. 6A) via the underside 51 and via an axis of rotation 52. At the upper side 53, the massage head 42 has a circular massage tool 54 with a bearing ring 55 and six bulbous massage rollers 56 rotatably mounted therein. The axes 57 of the massage rollers 56 form the spokes of the bearing ring 55 and are arranged radially between a central hub 58 and an outer ring 19/42 19 R 618 9 8 59. The massage tool 54 is not only rotatable about the axis of rotation 52, but also pivots thanks to a gimbal 60 of the hub 58 against the rest of the massage head 42 in all directions. Below the massage tool 54, the massage head 42 has a rotating guide 61 of the bearing collar 55. Between a limiting ring 63 and the circular bottom 62 of the massage head 42 an elastic seal (not shown) is provided. An elastic seal is also provided for the upper portion of the massage head 42. The assembly takes place on the intermediate ring 65 and the rotating axis 52 with a sealing ring. Above the bottom 62 several drives 64 are visible. The limiting ring 63 limits the pivoting angle of the massage tool 54 and thus protects the drives 64 from collisions with the massage tool 54. The drives 64 can determine the rotation of the massage head 42 and / or the rotation and pivoting of the massage tool 54 on the one hand.
    In case of sleep disturbances or to increase the comfort, a massage device 38 can carry out temporally controlled massage programs to support the process of falling asleep, to shorten awake periods or as an alarm function. In the case of automation, the massage is available at any time and several times a day, which is hardly possible with manual massages performed by caregivers. Since the described support device 1 together with tensioning devices 7 and massage device 38 works very quietly, even during the night's sleep and even in occupancy in shared rooms no massage, local or global cooling or heating or a change in Gurtvorspannungen be waived.
    As can be seen in FIG. 6A, the support device 1 can also be connected to an operator computer (HMI) 43 which, for example, allows the configuration of a pretension profile or a massage program. The data of the force sensors 22 could also be recorded, evaluated and, for example, used to select or optimize the massage.
    Of course, other medical equipment and aids, such as detectors or recording devices for X-ray diagnosis, can be used as a treatment device 39.
    In Fig. 6D, a massage head 42 for local heating or cooling is shown. The massage head 42 is connected to the underside 51 and via a rotation axis 52 to the massage device 38 (see Fig. 6A). For local heating, an electric resistance heating or heat lamp is integrated in the massage head housing 66 in the massage head. For local cooling, the massage head housing 66 is made of a high heat capacity material, e.g. Copper, executed. For cooling, the massage head 42 is cooled in its tool holder to a predeterminable temperature.
    For the use of the support device 1, for example, as a hospital bed special functions in the third module 41 - the substructure - can be implemented. As can be seen in FIG. 7, this includes the mobility produced by rollers 44, the fixation by braking (not shown), but also the lifting,
    Lowering and tilting of the entire support surface 8 or of sub-segments 45, 46, 47 of the support surface 8 (see Part figures A to F in Fig. 7), to facilitate the care work and / or as security measures. In this case, the treatment device 39, as shown here by way of example on the massage device 38, can follow the changes in the support surface 8. The subfigures show in detail: A A flat treatment position for arbitrary body positions, wherein the support surface 8 is advantageously arranged approximately at waist height or working height of the treatment personnel; 21/42 21 R61898 B A flat entry position where the distance from the support surface 8 from the floor 48 corresponds approximately to the seat height of the user so that easy entry and exit is possible; this position is also chosen as a special sleeping position in case of danger of falling out or as an emergency position (for resuscitation); C An S-shaped seating position wherein a back segment 45 is tilted at about 45 ° (e.g., by means of a pressure cylinder 68 shown diagrammatically), two leg segments 47 are arranged to support an angled leg position and the entire second module 39 - e.g. by means of a telescopic cylinder device 69 - has a rising to the head end 49 inclination. This position is also used as an emergency position (Trendelenburg storage). The positions C and E must be able to be aligned very quickly. In this case, the massage device 38 is arranged in a position for massage of the thigh of the user; D A slightly upright lying position with raised back and leg segments 45, 47; E A flat reclining position with the second module 39 having a slope rising from the foot 50; and F A seating position as in Part D, wherein the massage device 38 is disposed in a position to massage the lumbar region of the user; wherein the positions C and E can be aligned very quickly.
    Furthermore, an example electrical auxiliary drive can be provided to facilitate the change of location frequently moving beds.
    Schematically, as mentioned in Fig. 7C, two lifting devices 68, 69 are shown by way of example. Comparable (or other known) lifting devices or lifting columns can be used for the other segments or modules, which is shown in the drawing of the 22/42 22 R61898
    For simplicity's sake not shown.
    Although the support device 1 shown in particular can develop their benefits in the hospital as a hospital bed, but it can also work, private, care and wellness in the form of a bed or chair, seat (eg in transport such as car, Train, bus or plane), as an armchair or as a sunbed (eg sun lounger in outdoor area) are used. In the private sector, the arrangement can optionally be simplified accordingly and, for example, be dispensed with a modular design. 23/42
