The invention relates to an electromotive adjustable support device referred to in the preamble of claim 1 for a padding of a seat and / or reclining furniture.

Such support means are well known, for example by the., For example in the form of electric motor adjustable bed bases of beds EP 0 372 032 B1 . DE-U-299 17 813 . DE-A-10 2006 030 674 and DE 199 62 541 C3 ,

By DE-U-20 2007 015 811 and DE-U-202 10 187 are drives for support devices, in particular slatted frames known, but not integrated into the support means, but are formed as recorded in a separate housing double drives.

By DE 38 42 078 C2 is an electric motor adjustable support means of the type in question for upholstering a sitting and / or lying furniture known. The known support means comprises a first support member and a pivotable about a pivot axis second support member, between which a third support member is arranged. In the known support means, the first support member is a stationary support member, while the second support member is a head support member and disposed between the first support member and the second support member third support member is an upper body support member. The known support means has a electromotive drive, which has an adjusting element which is the same via an actuating element with the second support member for pivoting in power transmission connection. In the known support means, the second support member is rotatably connected to a rotatably mounted shaft, is rotatably connected to an articulated lever. The adjusting element is in the known support means a slide which is connected to a spindle nut of a spindle drive. In operation of the known support means, the slider presses against the linkage, so that the shaft to which the second support member is connected, is rotated. In this way, the second support member is pivoted.

Out EP 1 702 536 A an electric motor adjustable support device according to the preamble of claim 1 is known.

The invention has for its object to provide an electric motor adjustable support means referred to in the preamble of claim 1 species whose structure is simplified and thus designed more cost-effective and whose height is kept low.

This object is achieved by the invention defined in claim 1.

According to the invention the actuating element is rod-like and guided by the adjusting linear linearly displaceable in a guide, which is preferably formed in or on the third support member. According to the invention, the actuating element for pivoting the second support member engages eccentrically to the pivot axis of the second support member. According to the invention, the second support member can be pivoted, for example, and in particular by the fact that the actuating element, which may be designed, for example, in the manner of a plunger, presses eccentrically to the pivot axis against the second support member. In this way, an articulated lever to be connected to a pivot shaft is initially no longer required, so that the structure of a support device according to the invention already so far simplified and designed more cost-effective. In addition, a rotationally fixed connection of the support member to be pivoted with a pivot shaft is no longer required in a support device according to the invention.

Since the rod-like actuating element can be mounted, for example, and in particular in a guide which is formed in the third support part, the components required for introducing an adjusting force into the second support part do not increase the overall height of the support device. Compared with known support means so that the height is significantly reduced.

Overall, this results in a simple, cost-effective and robust design with few components and low overall height.

The support device according to the invention may be, for example, a slatted base, which serves to support a mattress of a bed. However, the support device according to the invention may, for example, also be a couch, in particular a garden lounger, or any other seat and / or reclining furniture.

According to the invention, there is at least one further support member pivotable about a pivot axis, the further support member being associated with a further actuating element which is linearly displaceably guided in a guide which is formed in or on the support member adjacent to the further support member, the further one Actuating element for pivoting the further support member acts eccentrically to the pivot axis of the further support member. In this embodiment, the basic principle according to the invention is used for simultaneous or temporally successive pivoting of several support parts.

An extraordinarily advantageous development The invention provides that at least one support member remote from the guidance of a guided on the support member actuating element has a contact surface, wherein in a first kinematic phase, the adjusting element or arranged on an adjacent support member actuating element with an active surface on the actuating element comes to rest and this linearly displaced and wherein in a second kinematic phase, the adjusting element or arranged on the adjacent support member actuator comes with its effective surface on the contact surface of the support member eccentrically to the pivot axis to the plant and pivots the support member about the pivot axis. In this embodiment, by means of a particularly simple structure, for example, a headrest part and an upper body support part can be adjusted relative to a stationary support part. In the first kinematic phase, the adjusting element, for example a slider of a spindle drive arranged on the stationary support part, displaces linearly an actuating element guided on the upper body support part. The actuator engages eccentrically to the associated pivot axis of the headrest part, so that it is pivoted in the linear displacement of the actuating element. As soon as the slider comes to rest on the contact surface of the upper body support member, the actuator is not further linearly displaced, so that the headrest part is not pivoted further. Instead, the slider presses in the second kinematic phase eccentrically to the associated axis of rotation against the upper body support member, so that this - together with the already pivoted headrest part - is pivoted. The corresponding kinematics of the support parts is thus realized by only a few components.

Another extremely advantageous development of the invention provides that the adjustment at least one actuating element and / or at least one actuating element an adjacent actuating element and / or at least one actuating element, the associated support member applied loosely. This embodiment is particularly advantageous when the force-transmitting components are claimed in the drive train of the support device during the pivoting of a support member or several support members to pressure. If the force-transmitting components or at least one of these components is claimed during the pivoting of a support member to train, however, the adjusting element with an actuating element or an actuating element with an adjacent actuating element or an actuating element with the associated support member can be firmly connected.

Another advantageous embodiment of the invention provides that at least one actuating element is claimed during the pivoting of the associated support member to pressure. In this way, a particularly simple structure, since in particular the actuating element can act on the associated support member loose.

According to another advantageous development, at least one actuating element is designed in the manner of a plunger.

The adjusting element can be designed in any suitable manner, preferably by the output member of a linear drive. In that regard, an advantageous development of the invention, that the adjusting element is a spindle nut or is connected to a spindle nut which is arranged against rotation and movable in the axial direction on a rotatably driven threaded spindle. Such spindle drives are available as simple and robust standard components and are suitable for transmitting large forces.

An advantageous development, in particular of the embodiment in which at least one actuating element is claimed during the pivoting of the associated support member to pressure, provides that the adjusting element is designed as a slide. In combination with the aforementioned embodiment, the slider may be formed by the spindle nut or connected to the spindle nut.

Another extremely advantageous development of the invention provides that the length of the actuating elements and in each case the distance of the active surface of an actuating element of the contact surface of the associated support member in an unadjusted position of the support members are dimensioned so that the support members pivot in chronological succession. In this way, a particularly ergonomic adjustment can be realized in which pivoted first, for example, a headrest part and then an upper body support part of a slatted frame. The number of support members is selectable within wide limits in all embodiments of a support device according to the invention.

Another embodiment of the invention provides that the lengths of the actuating elements and in each case the distance of the active surface of an actuating element of the contact surface of the associated support member in the unadjusted position of the support members are dimensioned so that the support members pivot at the same time or substantially simultaneously.

In terms of a simple and inexpensive construction using as few different components as possible, another advantageous development provides that the actuating elements have substantially the same length.

Another embodiment of the invention provides that in an unadjusted position, the distance of Active surface of an actuating element of the contact surface of the associated support member of the adjusting element closest to the actuating element to the adjustment element farthest located actuator decreases. At substantially the same length of the actuators results in this embodiment, a kinematics in which the adjustment element and thus the drive farthest support member pivot first and then successively pivot the drive closer to the support parts.

Another advantageous embodiment of the invention provides that the support means is formed as a slatted frame, wherein the support members have resilient slats for supporting a mattress of a bed.

Another development of the invention provides that the support device is designed as a couch, especially as a garden lounger.

The number of support parts can be selected within wide limits according to the respective requirements. According to the respective requirements, for example, a support means with a single adjustable support member or a support means with a plurality of mutually adjustable support members can be realized.

The invention will be explained in more detail with reference to the accompanying drawings, in which embodiments of a support device according to the invention are illustrated. All the features described in the drawing and claimed in the claims, taken alone and in any combination with each other form the subject of the invention, regardless of their summary in the claims and their back references and regardless of their description or representation in the drawing.

The Figures 1-4 do not represent an embodiment according to the invention. They serve exclusively as Ausauschungsbeispiel.

In the figures of the drawing, the same or corresponding components are provided with the same reference numerals.

The exemplary embodiments of the support device according to the invention shown in the drawing are designed as slatted frames, wherein for reasons of clarity, in each case only the main body of the slatted frame without slats is shown.

In Fig. 1 is shown in partially sectioned side view a Auschanungsbeispiel a support means 2 in the form of a slatted frame, which has a first support member 4, which is formed in this case by a stationary support member. The support device 4 further comprises a second support member 6, which is formed in this embodiment by a headrest part. In the longitudinal direction of the support means 2, a third support member 8 is arranged between the first support member 4 and the second support member 6, which is formed in this Auschanungsbeispiel by an upper body support member. In the drawing, only one intended to support the upper body and head support member 8 and 6 part of the support means 2 is shown. A to support the calf or leg area provided part of the support means 2 is constructed accordingly and will therefore not be explained here.

The second support part 6 is articulated and about a horizontal pivot axis 10 which in Fig. 1 extends in the plane of the drawing, pivotally connected to the third support member 8, which in turn is articulated and about a horizontal pivot axis 12, the in Fig. 1 extends into the plane of the drawing, pivotally connected to the first support member 4. For pivoting the second support member 6 and the third support member 8 relative to each other and to the first support member 4, an electric motor drive 14 is provided, which will be explained in more detail below.

The electromotive drive 14 has an adjusting element, which is formed in this embodiment as a slide 16 which is reciprocable in the direction of a double arrow 18. The slider 16 is non-displaceably connected in this embodiment with a spindle nut 20, which is secure against rotation and in the axial direction movable on a threaded spindle 22 is arranged, which via a worm gear 24 with a in Fig. 1 unrecognizable electric motor is in rotary drive connection. According to the direction of rotation of the output shaft of the electric motor and thus the threaded spindle 22, the spindle nut 20 and thus the slider 16 moves in Fig. 1 to the right or left.

The slider 16 is connected via an actuating element 26 with the second support member 6 for pivoting the same in power transmission connection. According to the invention, the actuator 26 is rod-like and guided by the slider 16 linearly displaceable in a guide which is formed in the third support member 8. In the exemplary embodiment shown, the slide 16 acts loosely on the end of the rod-like actuating element facing away from the second support part 6, wherein the actuating element in this exemplary embodiment is designed in the manner of a plunger. In order to avoid a lateral buckling of the actuating element 26 under pressure load during pivoting of the second support member 6, the actuating element 26 is guided in the guide either over its entire length, or guide elements are provided at short intervals in the longitudinal direction of the actuating element 26, the distance thereof is chosen low, that a buckling of the actuating element 26 is avoided. The guide elements may be formed web-like or rib-like, for example.

How out Fig. 1 it can be seen, engages the rod-like actuator 26 for pivoting the second support member 6 eccentrically to the pivot axis 10 on the second support member 6 at.

The following is based on the Fig. 2A to 2C the underlying inventive adjustment explained in more detail. The Fig. 2A to 2C serve exclusively for Clarification of the underlying adjustment principle, so that the support members 4, 6, 8 are shown in a highly schematic and not to scale.

Fig. 2A shows the support members 4, 6, 8 in an adjustment position in which the support members 4, 6, 8 together span a substantially horizontal support plane. This adjustment corresponds to an unadjusted position of the support device. 2

As in Fig. 2A indicated, the actuating element 26 is guided on the third support member 8 in a guide 28 which is formed by a continuous channel-like recess, displaceable in its longitudinal direction on the third support member 8. Removes from the guide 28, in this Auschanungsbeispiel the third support member 8 on its the slider 16 facing end face on a contact surface 30, with a third support member 8 facing the effective surface 32 of the slider 16 in below with reference to FIG Figs. 2B and 2C cooperates closer explained way.

In a first kinematic phase, the slider 16 presses against the actuating element 26, so that this in Fig. 2A is moved to the right. Since the slider 32 remote from the end of the actuating element 28 acts eccentrically to the pivot axis 10 on the second support member 6, while the second support member 6 is pivoted counterclockwise.

Fig. 2B represents the end of the first kinematic phase in which the second Stüzteil 6 is pivoted relative to the third support member 8 maximum counterclockwise.

In a second kinematic phase, the active surface 32 of the slider 16 comes to the contact surface 30 of the third support member 8 to the plant. In the exemplary embodiment shown, the cross section of the slider 16 at its free end, that is to say in the region of the active surface 32, is larger, at least in one dimension, for this purpose As a result of this embodiment, in the second kinematic phase, the actuating element 26 is not displaced further relative to the third support part 8. Rather, in the second kinematic phase, the slider 16 presses eccentrically to the pivot axis 12 against the third support member 8, so that this pivots counterclockwise, as in Fig. 2C shown.

In this way, both the second support member 6 is pivoted by means of the actuating element, namely in the first kinematic phase, as well as the third support member 8, namely in the second kinematic phase.

Like from the FIGS. 2A to 2C it can be seen, the slider 16 acts on the actuating element 26 and the actuating element 26, the second support member 6 loose.

A provision of the support members 6, 8 in the in Fig. 2A shown starting position, which corresponds to an unadjusted position of the support means 2, under the weight of the support members 6, 8, but with the drive, wherein the spindle nut 20 and the slider 16 in Fig. 1 move to the left.

Fig. 3 shows the support 2 according to Fig. 1 in a Fig. 2B corresponding parking days.

Fig. 4 shows the support 2 according to Fig. 1 in a Fig. 2C corresponding adjustment, which corresponds to a maximum adjusted position of the support means 2.

Like from the Fig. 1 to 4 can be seen, the illustrated support means 2 allows a relatively simple structure an adjustment of the support members 6, 8. In addition, the support device 2 according to the invention Fig. 5-Fig. 7E a low height.

In Fig. 5 is a first in a perspective view Embodiment of a support device 2 according to the invention shown, which differs from the Auschanungsbeispiel according to Fig. 1 characterized in that in addition to the first support member 4, the second support member 6 and the third support member 8, a fourth support member 34, a fifth support member 36, a sixth support member 38 and a seventh support member 40 are provided. Respective adjacent support members 4-8 and 34-40 are hinged and pivotally connected to each other about a horizontal pivot axis 12 and 10 or 42 or 44 or 46 and 48, respectively.

Fig. 6A shows the support 2 according to Fig. 5 in a partially sectioned side view, wherein it can be seen that the further support members 34, 36, 38, 40 are each associated with a further designed in the manner of a plunger actuator 50 or 52 or 54 and 56 respectively. In the illustrated embodiment, the support members 6, 34, 36, 38 constructed in terms of their structure and the interaction with the associated actuator as described above with reference to the third support member 8. Similarly, the actuators 50, 52, 54, 56 are constructed as described above with reference to the actuator 26.

How out Fig. 6A Furthermore, it is apparent in the in Fig. 6A shown adjusting position in which the support members 8, 6, 34, 36, 38, 40 span a substantially horizontal support plane and which corresponds to an unadjusted position of the support means 2, the actuators 26, 50, 52, 54, 56 with their end faces loose together or the slider 16 and the support member 40 at.

The Fig. 6B to 6G represent different kinematic phases during the adjustment of the support means 2. For the sake of clarity are in the FIGS. 6B to 6F essentially exclusively the Reference number of the components referred to registered. To adjust the support parts of the support means 2, the threaded spindle 22 is rotationally driven so that the spindle nut 20 and thus the slider 16 in Fig. 6A moved to the right. Here, the slider 16 moves the actuator 26 in Fig. 6A to the right, so that this the actuators 50, 52, 54 and 56 also in Fig. 6A moves to the right. Here, first, the active surface of the actuating elements 26, 50, 52, 54 and the slider 16 is still each of the contact surface of the associated support member 8, 6, 34, 36, 38 away (see Fig. 2A ), so that the support members 8, 6, 34, 36, 38 initially remain unverschwenkt each other while the support member 40 is pivoted in the drawing counterclockwise until the in Fig. 6B shown Verschwenklage is reached.

In the in Fig. 6B illustrated position of the actuating elements, the active surface of the actuating element 54 comes eccentrically to the pivot axis 46 on the contact surface of the associated sixth support member 48 to the system, so that the sixth support member 48 about the pivot axis 46 relative to the fifth support member 36 in Fig. 6B is pivoted counterclockwise. Here, the active surfaces of the slider 16 and the actuating elements 26, 50, 52 are initially spaced even to the contact surfaces of the associated support members, so that the support members 8, 6, 34, 36 are not initially pivoted.

Fig. 6C represents an adjustment in which the active surface of the actuating element 52 on the contact surface of the fifth support member 36 eccentrically to the pivot axis 44 abuts, so that the fifth support member 36 in a further movement of the slide in Fig. 6C to the right in Fig. 6C is pivoted counterclockwise.

In a further movement of the slider 16 in Fig. 6C to the right, the active surface of the actuating element 50 comes to the contact surface of the associated fourth support member 34 eccentrically to the pivot axis 42 to the system, so that the fourth support member 34 about the pivot axis 42 in Fig. 6D is pivoted counterclockwise.

In a further movement of the slider 16 in Fig. 6 arrives in the Fig. 6E illustrated position, the effective area of the actuating element 26 on the contact surface of the associated second support member 6 eccentric to the pivot axis 10 to the system, so that the second support member 6 relative to the third support member 8 in Fig. 6E is pivoted counterclockwise.

In a further movement of the slider 16 in Fig. 6E comes to the right in the in Fig. 6F illustrated position of the slider 16 with its active surface on the contact surface of the associated third support member 8 eccentric to the pivot axis 12 to the system, so that the third support member 8 relative to the first support member 4 in Fig. 6F pivoted counterclockwise.

Fig. 6G represents the end position of the adjustment, which corresponds to a maximum adjusted position of the support parts of the support means 2.

From the foregoing description of FIGS. 6A to 6G It can be seen that the support members 40, 38, 36, 34, 6, 8, starting with the support member 40, are pivoted one after the other. In this case, an actuating element, for example the actuating element 54, initially displaces the adjacent actuating element, for example the actuating element 56, linearly, until it comes into contact with its active surface against the contact surface of the associated supporting part, for example the sixth supporting part 38. In a further movement of the actuating element 54 then the sixth support member 38 pivots. This also applies in the manner described for the further actuating elements 56, 52, 50, 26 or the slide 16.

How out Fig. 6A it can be seen, in the illustrated embodiment, the actuating elements 26, 50, 52, 54, 56 are formed substantially the same length. As further out Fig. 6A it can be seen, takes in the unadjusted position of the support means 2, the distance of the active surface of an actuating element to the contact surface of the associated support member, for example, the distance of the active surface of the actuating element 56 to the contact surface of the associated support member 40, of the slider 16 nearest actuator, ie the actuator 26, to which the slider 16 farthest actuator, namely the actuator 56, from. The particular desired kinematics is adjustable by appropriate choice of the lengths of the actuators.

In a modification of the embodiment according to Fig. 6 For example, it is possible to increase the length of the actuating element 52 and simultaneously reduce the length of the actuating element 54 so that at the same time the active surface of the actuating element 54 on the contact surface of the sixth support member 36 and the active surface of the actuating element 52 on the contact surface of the associated fifth Support member 36 comes to the plant. In this case, the seventh support member 40 is pivoted relative to the sixth support member 38, while the support members 36, 38 are not pivoted relative to each other. In this way, the kinematics of the support members can be adapted to the respective requirements.

In Fig. 7A a second embodiment of a support device 2 according to the invention is shown, which is for supporting a on the support device. 2 resting person in the region of her upper body and head has four support parts 8, 6, 34, 36, similar to that in Fig. 6 illustrated first embodiment to horizontal and mutually parallel pivot axes 12, 10, 42, 44 are connected to each other or with a stationary support member 4. The embodiment according to Fig. 7A differs from the embodiment according to Fig. 6 above all, characterized in that the support members 8, 6, 34, 36 associated rod-like actuators tensile and pressure-resistant connected to each other. At the in Fig. 7A In the embodiment shown, the actuating element associated with the second supporting part 6 is formed by two rod-like actuating elements 26 ', 26 ", which are pivotably connected to one another and pivotable relative to one another about an eccentric pivot axis 10. The end of the actuating element 26' facing away from the supporting part 6 is articulated and connected about a pivot axis 60 parallel to the pivot axis 60 with another actuator 62, the 26 'remote from the actuating element end hinged and about a pivot axis 10 parallel to the pivot axis 64 is pivotally connected to the slider 16.

The slide 16 remote from the end of the actuating element 26 'is articulated and connected to a parallel to the pivot axis 10 pivot axis 66 with the actuating element 50'. In this way, the actuating element 50 "is articulated and connected to the actuating element 52 'about a pivot axis 68 parallel to the pivot axis 42. The end of the actuating element 52' facing away from the actuating element 52 is articulated and about a pivot axis 70 parallel to the pivot axis 44 connected to the support member 36.

How out Fig. 7A it can be seen, for example, the pivot axis 60 to the pivot axis 12 eccentric arranged so that the pivoting of the support member 8, the actuator 62 eccentrically engages the pivot axis 12 on the support member 8. In a corresponding manner, the pivot axis 66 is arranged eccentrically to the pivot axis 10, the pivot axis 68 eccentric to the pivot axis 42 and the pivot axis 70 eccentrically to the pivot axis 44.

To adjust the support parts 8, 6, 34, 36 from the in Fig. 7A shown adjustment, the electric motor drives the threaded spindle 22 so that the slide 16 in Fig. 7A moved to the right, so that the actuation elements 62, 26 ', 26 ", 50', 50", 52 "and 52" are subjected to pressure due to the arrangement of the pivot axes 60, 66, 68 and 70 eccentric to the pivot axes 12, 10, 42 and 44 are in this case the support members 8, 6, 34, 36 in the in the Fig. 7B to 7E shown pivoted until the in Fig. 7E shown end position of the pivoting movement is reached.

The adjustment of a resting on the support device 2 person in the calf / leg serving support portion 72 is carried out in a corresponding manner and will therefore not be explained in more detail. A threaded spindle 22 'assigned to the support section 72 can be rotationally driven independently of the threaded spindle 22, so that the support parts of the support section 72 can be adjusted independently of the support parts 8, 6, 34, 36. However, it is also possible, the threaded spindles 22 and 22 'rotatably connected to each other, so that the adjustment of the support parts of the support portion 72 to the adjustment of the support members 8, 6, 34, 36 is coupled. For example, and in particular one of the threaded spindles 22, 22 'can then have a left-hand thread and the other a right-hand thread.
