- the padding device according to the invention gives the visual impression of a conventional mattress without an electric motor-driven adjustment device and a loading/relief device.
- a further advantage of the padding device according to the invention is that it has a low installation height.
- One advantageous further embodiment of the invention provides that the loading and relief device for achieving pressure loading or relief acts on least one spring element.
- at least one spring element is thus acted on with pressure or is relieved of pressure by the loading and relief device.
- the loading and relief device may operate according to any given suitable operating principle, and may be designed as a pneumatic loading and relief device, for example.
- the loading and relief device is an electromechanical loading and relief device.
- electromechanical devices have a relatively simple, inexpensive design, and allow pressure loading or relief, corresponding to any given kinematics, within broad limits.

An electric motor-driven adjustment device is provided for adjusting the support parts relative to one another.
- A support device is known from DE 10 2010 021 362 A1, in which a loading/relief device for achieving pressure loading or relief of the padding is provided. The pressure loading/relief device is situated beneath the base body of the support device.
- Similar support devices are also known from DE 10 2008 031 043 A1, DE 20 2005 009 180 U1, WO 2012/052972 A1, and DE 29509909 U1.
- An object of the invention is to provide an adjustable padding device for seating and/or lounging furniture, having expanded functionality.
- This object is achieved by the invention set forth herein.
- According to the invention, the functionality of the padding device is expanded by providing a loading/relief device for achieving pressure loading or relief of the padding element, the loading/relief device being accommodated in a shared casing.
- In this way, it is possible not only for the padding device to be adjustable by electric motor, but also for it to carry out a massage function, for example. As a result of all components of the padding device, including the loading/relief device, being accommodated in the shared casing, the padding device according to the invention gives the visual impression of a conventional mattress without an electric motor-driven adjustment device and a loading/relief device.
- A further advantage of the padding device according to the invention is that it has a low installation height.
- One advantageous further embodiment of the invention provides that the loading and relief device for achieving pressure loading or relief acts on least one spring element. In this embodiment, at least one spring element is thus acted on with pressure or is relieved of pressure by the loading and relief device.
- The loading and relief device may operate according to any given suitable operating principle, and may be designed as a pneumatic loading and relief device, for example. In this regard, one particularly advantageous further embodiment of the invention provides that the loading and relief device is an electromechanical loading and relief device. Such electromechanical devices have a relatively simple, inexpensive design, and allow pressure loading or relief, corresponding to any given kinematics, within broad limits.
- One advantageous further embodiment of the above-mentioned embodiment provides that the loading and relief device has at least one electric motor that is in operative connection with at least one pressure element, by means of which a pressure force is or may be exerted on at least one spring element in order to achieve pressure loading or relief.
- This results in a particularly simple design of the loading and relief device, in that the electric motor drives at least one pressure element that provides pressure loading or relief of the padding. In principle, a single pressure element is sufficient for achieving pressure loading or relief. According to the invention, however, two or more pressure elements may also be provided, so that the number of pressure elements is selectable within broad limits, depending on the particular requirements. The same correspondingly applies for the design of the pressure elements. Furthermore, according to the invention it is sufficient in principle when a single electric motor is provided. However, two or more electric motors may be provided if necessary, depending on the particular requirements.
- Another advantageous further embodiment of the invention provides a control device for controlling the electric motor or the electric motors. The control device may in particular have a manual switch via which a user of the support device may select whether, to what extent, or corresponding to which kinematics, pressure loading or relief is to be exerted.
- One advantageous further embodiment of the above-mentioned embodiment provides that the control device controls the electric motor or the electric motors in such a way that the pressure element or the pressure elements act(s) on at least two spring elements sequentially in time. In this embodiment, the pressure loading or relief of an individual spring element may vary over time, so that, due to appropriate pressure loading or relief of adjacently situated spring elements, pressure loading or relief that varies over time, and in particular is “rolling,” may be achieved, as is known per se for so-called massage chairs, for example.
- One advantageous further embodiment of the above-mentioned embodiment provides that the control device controls the electric motor or the electric motors in such a way that at least one pressure element acts on at least two spring elements sequentially in time. This results in a particularly simple design.
- Another extremely advantageous further embodiment of the invention provides that the or each pressure element loosely acts on the or each associated spring element. In this embodiment, a connection between the pressure element and the associated spring element is not necessary, thus simplifying assembly and disassembly of the loading and relief device, also for maintenance, for example. Another advantage of this embodiment is that the pressure element acts on an associated spring element with pressure for achieving pressure loading, while the pressure element is otherwise not in contact with the spring element, so that the spring element then develops its full spring effect.
- Another advantageous further embodiment of the invention provides that the spring elements are bed frames.
- According to another further embodiment of the invention, the spring elements may also be elastic slats.
- The invention is explained in greater detail below with reference to the appended drawings, in which embodiments of a support device according to the invention is illustrated. All features that are described, illustrated in the drawings, and claimed in the patent claims, alone or in any combination, constitute the subject matter of the invention, regardless of their description or illustration in the drawings, and regardless of their recapitulation in the patent claims.

FIG. 1 illustrates one embodiment of a padding device according to the invention that is adjustable by electric motor, having asupport device 2 for supporting padding of seating and/or lounging furniture, in particular a mattress of a bed. In the illustrated embodiment, thesupport device 2 is designed as described in EP 1 239 753 B1, the contents of which are hereby fully incorporated by reference into the present patent application. - As described in EP 1 239 753 B1, the
support device 2 has a base body with at least two support parts that are adjustable relative to one another, and on which spring elements are situated which support the padding when the support device is being used.FIG. 1 illustrates a padding element 4 in the form of a mattress. As further described in EP 1 239 753 B1, the padding element 4 together with thesupport device 2 and an electric motor-driven adjustment device is joined to form a unit for adjusting the support parts relative to one another. - The padding element 4 together with the
support device 2 and the electric motor-driven adjustment device is accommodated in a shared casing which essentially completely surrounds the unit comprising the padding element 4 and thesupport device 2 together with the adjustment device. The casing is symbolically represented by a dashed line 6 inFIG. 3 . - The embodiment illustrated in the drawings is thus an adjustable padding device in the sense of EP 1 239 753 B1.
- In the illustrated embodiment, a charging/discharging device or loading/
relief device 8 is provided for achieving pressure loading or relief of the padding. The loading/relief device 8 may operate according to any given suitable operating principle. In the illustrated embodiment, the loading/relief device is depicted as a pneumatically operating device. For achieving pressure loading or relief, the loading/relief device acts on at least one spring element, for example an elastic slat, of the support device. For this purpose, in the illustrated embodiment the loading/relief device has a plurality of pressure elements situated in succession in the longitudinal direction of thesupport device 2; inFIG. 1 , only one pressure element is denoted byreference numeral 10. Thepressure elements 10 situated in succession in the longitudinal direction of thesupport device 2 act on spring elements situated in succession in the longitudinal direction of thesupport device 2. In the illustrated embodiment, thepressure elements 10 each have a cushion-like design and are inflatable by means of a pump. The pneumatic control takes place via valves in such a way that thepressure elements 10 are inflatable independently of one another. - As indicated in
FIGS. 2 through 4 , the loading/relief device is situated within the profile height of the base body of thesupport device 2. According to the invention, an arrangement of the loading/relief device 8 within the profile height of the base body of thesupport device 2 is understood to mean that the components of the loading/relief device 8 are situated within an upper delimiting plane and a lower delimiting plane that are defined, respectively, by the top side and the bottom side of the base body of thesupport device 2, while pressure elements, by means of which the loading/relief device 8 brings about pressure loading or relief of the padding, protrude beyond the profile height during operation of the loading/relief device. In the illustrated embodiment (seeFIG. 2 ), thepressure elements 10 are situated within the profile height of thesupport device 2 in the uninflated state, whereas in the inflated state they protrude beyond the profile height, as required for achieving pressure loading of the padding 4. - According to the invention, the loading/
relief device 8 is accommodated in the shared casing 6, as illustrated inFIG. 3 . - In the illustrated embodiment, the padding has a
foam cover 12 on which a user lies during use of thesupport device 2. By inflation of thepressure elements 10, a pressure force is exerted on spring elements, for example elastic slats of thesupport device 2, situated between thefoam cover 12 and thepressure elements 10; the spring elements transmit the pressure force to thefoam cover 12 on which a user lies during use of thesupport device 2. A massage effect, for example, is achievable in this way. - Although the loading/
relief device 8 is illustrated in the drawings ofFIGS. 1-4 as a pneumatically operating device, in practice it is preferred for the loading/relief device to be an electromechanical loading/relief device having least one electric motor that is in operative connection with at least one pressure element, by means of which a pressure force is or may be exerted on at least one spring element in order to achieve pressure loading. - For controlling the electric motor or the electric motors, a control device is provided that preferably controls the electric motor or the electric motors in such a way that the pressure element or the pressure elements act(s) on at least two spring elements sequentially in time. The control device preferably controls the electric motor or the electric motors in such a way that at least one pressure element acts on at least two spring elements sequentially in time. In this way, rolling pressure loading may be provided, as is known for so-called massage chairs, for example.
- In the sense of a simple and maintenance-friendly design, it is preferred that the or each pressure element loosely acts on the or each associated spring element. This means that the pressure element has no fixed mechanical connection to the spring element, and in the active state exerts a pressure force on the associated spring element, while the pressure element in the inactive state is retracted by the spring element, so that in this state the spring effect of the spring element is not impaired, and in this state the spring element is thus freely resilient and its spring effect is thus not adversely affected in this state.
- Accordingly, in
FIGS. 5-11 , there is shown in another preferred embodiment of the invention, asupport device 2 directed to the use of springs to carry out the invention. -
FIG. 5 depicts asupport device 2 which is part of the padding device according to the invention.

pressure exerting element 36 is adjustable relative to the support plane defined by theslats pressure exerting element 36 relative to the support plane, as symbolized by adouble arrow 40 inFIG. 6 , theadjustment drive 38 including a second electric motor. The adjustment drive 38 will be described hereinafter in greater detail with reference toFIG. 11 . - The
slats broken lines FIG. 6 . - In use, in order to cause a massage effect upon a user resting on the padding device, the
first slide 28 is moved along its linear axis by means of the firstlinear actuator 28 to the left inFIG. 6 . - The
pressure exerting element 36 is adjusted toward the lower side of theslats adjustment drive 38, so as to interact with theslats -
FIG. 7 depicts the interaction between thepressure exerting element 36 and theslat 24, wherein thepressure exerting element 36 is charging theslat 24 so as to protrude over the support plane. As can been seen fromFIG. 7 , thepressure exerting element 36 abuts against the side of thestrap 40 facing away from theslats - As it is evident from
FIGS. 6 and 7 , upon linear motion of thefirst slide 28 along the longitudinal direction of thesupport device 2, the slats may be charged consecutively so as to effect a ‘rolling’ massage effect. - An embodiment for putting the basic principle illustrated in
FIG. 6 andFIG. 7 into practice will now be explained in greater detail with reference toFIG. 8 toFIG. 11 . -
FIG. 8 depicts thesupport device 2, wherein some of slats are omitted in order disclose details of the charging/dischargingdevice 26. - In this embodiment, in addition to the charging/discharging
device 26, a further charging/dischargingdevice 26′ is provided. The charging/dischargingdevices devices device 26 will be described in greater detail. For ease of reference, inFIGS. 9 to 11 only the charging/dischargingdevice 26 is shown, while the charging/dischargingdevice 26′ is omitted. - Referring now to
