Electromotive adjustable slatted frames usually have a Verstellbeschlag on it serves to transmit the adjustment of an electric motor or more electric motors on the mutually adjustable support members of the slatted base. For mounting an electric motor adjustable slatted base, for example, a double drive is mounted on the slatted frame so that its adjusting elements come into operative connection with the adjustment fitting of the slatted frame.

The invention has for its object to provide an electromotive adjusting device for a support means for supporting the upholstery of a seat and / or reclining furniture, in particular a mattress of a bed, which is simple in construction and in use.

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

The invention provides a retrofit kit with which support devices, which are not or not electromotive adjustable, can be retrofitted with an electromotive adjustment, so they get the functionality of an electromotive adjustable support device. For this purpose, the invention provides an insertable between the support means and the padding subframe having a base body with at least two under the pulling action of a traction cable of a Bowden cable, which is in train connection with an electric motor drive unit, pivotable relative to each other protective parts.

For retrofitting example, a not or not electromotively adjustable slatted frame of the subframe between the slatted frame and the mattress is inserted, so that the mattress in the areas in which the subframe along the extension extends the slatted frame, supported on the subframe and in the other areas on the slatted base. By actuating the electric motor drive unit, the frame parts of the subframe are verschwnkt each other. If the subframe is inserted, for example, in an area in which the upper body of a person resting on the mattress, so when adjusting the frame parts of the subframe relative to each other, the mattress is raised in the region of the upper body, so that the same functionality results as in a slatted frame, the upper body support member is adjustable by an electric motor.

The invention thus makes it possible in a particularly simple and cost-effective manner to retrofit slatted frames or other support devices with the functionality of an electromotive adjusting device.

Since according to the invention, the adjustment of the frame parts relative to each other via at least one Bowden cable, the subframe of the retrofit kit according to the invention has only a small height, so that the subframe increases the height of the slatted frame including mattress only slightly.

In order to maintain the spring comfort of a slatted frame even when the subframe is inserted, the frame parts of the subframe can be provided with resilient slats or other spring elements on its side which faces the wall when using the retrofit set of the upholstery, for example the mattress.

The retrofit kit according to the invention is particularly well suited for use in the hospital or care sector, because the components of the subframe are insensitive to liquids and sensitive to liquids electromotive Drive unit of the retrofit kit with appropriate length of the Bowden cable or the Bowden cables can be located away from the actual subframe.

In addition, however, the retrofit kit according to the invention is also suitable for other applications. For example, the retrofit kit can be used in hotels. If the hotel beds of a hotel are not equipped with an electromotive adjusting device for cost reasons, an inventive retrofit kit can be used if a hotel guest wishes a corresponding functionality.

According to the invention, the subframe can consist of more than two frame parts, wherein mutually adjacent frame parts can be pivotally connected to one another and pivotable about a horizontal pivot axis relative to each other. In terms of a simple structure, it is advantageous if the base body consists of a first frame part and a second frame part which can be pivoted relative to the first frame part, as is provided by an advantageous development of the invention. In this embodiment, the frame consists of only two pivotable relative to each other frame parts, with which, however, for example, the functionality of an electric motor adjustable upper body support member of a slatted frame can be modeled.

Another advantageous embodiment of the invention provides that the length of the subframe in the longitudinal direction of the support means is substantially less than the length of the support means. For example, and in particular, the subframe may extend only over half or two-thirds of the length of the support means.

Another advantageous embodiment of the invention provides that an adjusting member for pivoting the frame parts of the subframe relative to one another is under the pulling action of the traction cable of the Bowden cable pivotable pivot lever. In this way, a particularly simple, inexpensive and robust construction results.

The operative connection between the pivoting lever and the frame parts which can be pivoted relative to one another by means of the pivoting lever can be produced according to the respective requirements in accordance with the invention. An advantageous development of the invention provides insofar as one end of the pivot lever slidably supported on a support and the other end of the pivot lever is mounted on a two-armed lever whose first lever arm is pivotally connected to one of the frame parts and the second lever arm by means of a linear guide is guided on the other frame part. This embodiment allows a pivoting of the frame parts relative to each other with an adjusting device, which consists of only a few components.

According to the invention, the linear guide can be formed on a separate component, which is connected to the associated frame part. To further simplify the structure, an advantageous development of the invention provides that the linear guide has a profile rail which forms a longitudinal spar of one of the frame parts.

A development of the aforementioned embodiment provides that the profile rail is a C-profile rail.

How out Fig. 2 it can be seen, the outer frame 14 laterally spaced, in the longitudinal direction of the slatted base 2 extending longitudinal beams 20, 22, which are connected to each other in the region of their ends by transverse bars 24, 26. In the context of the invention, the direction along which the slatted base 2 has the greater extent is defined as the longitudinal direction of the slatted frame 2. Accordingly, the transverse direction of the slatted base 2 is defined as the direction along which the slatted frame 2 has the lesser extent.

Fig. 3 The mounting frame 16 has longitudinal bars 28, 30, which are connected to one another in the region of their ends by means of transverse bars 32, 34. In the illustrated embodiment, the transverse bars 32, 34 are each formed by a profile rail, which has the cross-section of a horizontal C and are arranged or guided in the adjusting members of the mounting frame 16, as described below with reference to FIG Fig. 11 is explained in more detail.

In the illustrated embodiment, the mounting frame 16 is configured width adjustable to adapt to slatted frames of different widths. In order to realize the width adjustability, telescopic elements 36, 38 and 40, 42 extending in the direction of the other longitudinal beam 30, 28 are arranged on the longitudinal beams 28, 30 of the mounting frame 16, which are formed in the illustrated embodiment as pipe parts and in the right Angle to the longitudinal beams 28 and 30 extend. In the telescopic elements 36, 38, the ends of the cross member 32 are guided telescopically in the illustrated embodiment.

Fig. 2 ) of the slatted frame 2. Specifically, the longitudinal beams 28, 30 of the mounting frame 16 are pulled apart so far that the distance between the outer surfaces of the longitudinal beams 28, 30 of the mounting frame of the clear width between the inner surfaces of the longitudinal beams 20, 22 of the outer frame 14 corresponds. In this case, slide the cross members 32, 34 of the mounting frame 16 in the telescopic elements 36, 38 and 40, 42. After setting the desired width of the mounting frame 16 is inserted into the outer frame, as in Fig. 2 shown. Subsequently, the mounting frame 16 can be attached to the outer frame 14, for example by screwing.

After assembly of the mounting frame 16 on the outer frame 14, the support members 6 to 14 of the slatted frame 2 can be connected to the mounting frame 16.

Fig. 4 shows an example of a compound of the upper body support member 8 with the mounting frame 16. The connection of the leg support member 10 together with its associated calf support member 12 is carried out in a corresponding manner and will therefore not be discussed here. For connection to the upper body support member 8, a mounting means for pivotally supporting at least one pivotally adjustable support member is formed on the mounting frame, wherein the storage device in the illustrated Embodiment laterally spaced bearing bushes, in which the upper body support member 8 is inserted with laterally spaced bearing journals.

The drive unit 18 has two drive trains 50, 52, to each of which an electric motor 54 or 56 is assigned and whose output member is formed in each case by spindle nuts 58, 60. The sheaths of the Bowden cables 44, 44 'and 46, 46' are fixed to the housing 48 of the drive unit 18, while the traction cables of the Bowden cables are fixed in pairs to the spindle nuts 58, 60. In the illustrated embodiment, the traction cables of the Bowden cables 44, 44 'are fixed to the spindle nut 58, while the traction cables of the Bowden cables 46, 46' are fixed to the spindle nut 60. The electric motors 54, 56 are independently controllable. Control means for controlling the electric motors 54, 56 are not shown in the drawing for reasons of clarity. The same applies to power supply means, which are also not shown for reasons of clarity.

Fig. 6 shows the drive unit 18 according to Fig. 5 , for reasons of clarity, the Bowden cables 44, 44 and 46, 46 'are omitted. The powertrain 50 and its mode of operation will be explained in more detail below. The drive train 52 is constructed accordingly and will therefore not be explained in detail.

The electric motor 54 of the drive train 50 has a trained as a worm gear worm drive shaft 62 which is in engagement with a worm wheel 64 which is rotatably connected to a rotatably mounted in the housing 48 threaded spindle 66 is connected. In the illustrated embodiment, the worm 62 and the worm wheel 64 are part of a gear assembly, which, as shown Fig. 6 it can be seen, even more gear elements has, but in the present context, no further interest and therefore not be explained in detail.

On the threaded spindle 66 is secured against rotation and in the axial direction, the spindle nut 58, at which the Bowden cables 44, 44 '(in Fig. 6 not shown). For adjusting a support member of the electric motor 54 drives the threaded spindle 66 such that the spindle nut 58 in Fig. 6 moved to the left, so that the spindle nut 58 pulls on the traction cables of the Bowden cables 44, 44 '. The pulling action on the traction cables of the Bowden cables 44, 44 'is described below with reference to FIG Fig. 7 closer explained manner implemented in an erection of a raising lever, which forms an adjusting member of the mounting frame 16. A provision in the unadjusted position of the slatted frame (see. Fig. 1 ) takes place when the electric motor 54, but under the weight of the support member, possibly additionally under the load of a person resting on the slatted frame.

Fig. 7A shows a raising lever assembly 68 which has a first raising lever 70 which forms the adjusting member of the mounting frame 16 arranged furniture drive and under the pulling action of the traction cable of a Bowden cable can be set, in the illustrated embodiment under the pulling action of the traction cable of the Bowden cable 44 '. The first set-up lever 70 is pivotally erectable about a first pivot axis 72, wherein the first pivot axis 72 facing away from the first end lever pivotally and about a second pivot axis 72 parallel to the second pivot axis 74 pivotally connected to a second setting lever 76 which is connected to the traction cable of the Bowden cable 44th 'is operatively connected, such that the raising lever 70, 76 set up under the pulling action of the traction cable of the Bowden cable. In the illustrated embodiment, the traction cable of the in Fig. 7 Bowden cable, not shown, fixed to the end of the second setting lever 76 facing away from the first setting lever 70.

In the illustrated embodiment, the first set-up lever 70 is associated with a stop 78 which is formed on a stop member 80 which is non-displaceably connected to the longitudinal beam 30 of the mounting frame 16 (see. Fig. 11A ).

Hereinafter, the operation of the raising lever assembly 68 is explained in more detail, wherein on the Figs. 7A to 7E and on the Figs. 11A to 11E Reference is made. The Figs. 7A to 7E show only the set-up lever assembly 68 in combination with the stop member 80, while the FIGS. 11A to 11E additionally show the mounting frame 16. Among the Figs. 7A to 7E and 11A to 11E Figures with the same letter designate the same kinematic phase.

At the beginning of the adjustment movement, ie in the case of an uncovered slatted base 2, the pivot axes 72, 74 and a force application point of the Bowden cable 44 'on the second raising lever 76 in a plane, so that the raising lever arrangement under the pulling action of the traction cable of the Bowden cable 74 translational in Fig. 7A or 11A moves to the right. Out Fig. 11A It can be seen that the c-shaped profile of the longitudinal beam 30 of the mounting frame 16 forms a guide for the translational displacement of the set-up lever assembly 68. Due to the fact that in the first kinematic phase, the first pivot axis 72 and the second pivot axis 74 and the force application point of the traction cable of the Bowden cable 44 on the second setting lever 76 lie in one plane, the set-up lever assembly 68 in the first kinematic phase exclusively translational in FIG. 7A respectively. Fig. 11A moved to the right.

At the end of the first kinematic phase, the first set-up lever 70 runs on to a laterally, so in the axial direction of the first pivot axis 72 extending thickenings 82, 82 'on a lifting element 84 formed on the stop member 80. The lifting guide 84 is formed in the illustrated embodiment in cross-section arcuate. However, it can also be designed as an inclined plane.

Fig. 7B illustrates how the second setting lever 76 remote from the end of the first raising lever 70 runs onto the lifting guide 84 and is thereby raised, resulting in the consequence under the pulling action of the Zugseilsbowdenzuges 44 'to a setting up the raising lever 70, 76. Fig. 11B clarifies the resulting setting up the setting lever 70, 76th As from Fig. 7B and from Fig. 11B can be seen, the set-up lever assembly 68 performs during the second kinematic phase simultaneously both a translational movement and an erection.

Fig. 7C and Fig. 11C illustrate the end of the second kinematic phase at which the second setting lever 76 facing away from the free end of the first raising lever 70 runs onto the stop 78 formed on the stop member 80, so that a further translational movement of the set-up lever assembly 68 is prevented.

During an adjoining third kinematic phase, the first raising lever 70 executes exclusively an erecting movement, in which it pivots about the first pivot axis 72.

The Figures 7D and 11D represent the set-up lever assembly 68 in the third kinematic phase.

Fig. 7E and Fig. 11E show the raising lever assembly 68 at the end of the third kinematic phase in which the raising lever 70, 76 of the set-up lever assembly 68 are maximally positioned. In the Fig. 7E and Fig. 11E shown position of the raising lever assembly 68 corresponds to a maximum adjustment of the upper body support member 8 relative to the central support member. 6

Fig. 8 shows a perspective view of the stop member 80 taken by itself, the stopper 78 is particularly clearly visible.

Fig. 9 illustrates the emergence of the free end of the first raising lever 70 on the stop 78 at the end of the second kinematic phase.

Fig. 10 shows the first raising lever 70 during the third kinematic phase in which it executes exclusively a pivoting movement about the first pivot axis 72 and thereby abuts against the stop 78.

Fig. 12 illustrates the adjustment of the upper body support member 8 by means of the Verstellhebelanordnung 68. In the illustrated embodiment, the set-up assembly 68 applied to a longitudinal beam 86 of the upper body support member 8 loose by the longitudinal beam 86 loosely rests on the set-up lever assembly 68. Laterally spaced from the longitudinal beam 86, the upper body support member 8 has a further longitudinal spar 88, which is associated with a corresponding raising lever arrangement, however, for reasons of clarity in Fig. 12 not shown. The erecting lever arrangement associated with the longitudinal beam 88 interacts with the traction cable of the Bowden cable 44, the mode of operation being as described for the raising lever arrangement 68 and therefore not explained in detail here. Since the traction cables of the Bowden cables 44, 44 'on the same spindle nut 58 (see. Fig. 5 ) are set, the set up the longitudinal members 68, 88 Aufstellhebel arrangements completely synchronously, so that twists of the upper body support member 8 are reliably avoided during the adjustment.

Fig. 12B and 12C clarify the further adjustment of the upper body support part. 8 Fig. 12D shows the end position of the adjusting movement, which corresponds to a maximum adjusted position of the upper body support member 8 relative to the central support member and the mounting frame 16.

Based on Fig. 13 and 14 Be subsequently explained the first raising lever 70 associated locking means, wherein Fig. 13 the first set-up lever 70 and Fig. 14 the stop element 18 taken individually. The first raising lever 70 are assigned locking means which are effective in a predetermined Aufstelllage the first raising lever and lock the first set-up lever 70 against a translational movement, at the same time allow a raising movement of the first raising lever. In the illustrated embodiment, the locking means become effective when the first raising lever 70 adjacent to the stop 78 and pivotally a predetermined Setting position reached. In the illustrated embodiment, the locking means have a (see. Fig. 13 ) Bearing pin 90 which is formed on the first pivot axis 72 facing the end of the first deployment lever 70. The bearing journal 90 is designed and arranged such that it is rotatably or pivotally mounted in the locking position in a bearing recess formed on the stop element 80 and is released in an unlocking position from the bearing recess.

How out Fig. 13 can be seen, the bearing pin 90 has a circular cross-section bearing portion 92 and a flattening 94. As a result, the bearing portion 92 in the illustrated embodiment is approximately semicircular in cross section. Out Fig. 13 is not apparent and therefore it is explained here that the first raising lever 70 has on its side facing away from the bearing pin 90 a corresponding journal.

Fig. 14 shows a perspective view of the stop member 80. The stop member 80 has a groove 96 which opens at its end in a sectionally circular in cross-section bearing surface portion 98 whose diameter is greater than the inside diameter of the groove 96th

• Wie oben anhand von Fig. 7B beschrieben, läuft während der Verstellbewegung das dem zweiten Aufstellhebel 76 abgewandte Ende des ersten Aufstellhebels 70 auf die Hubführung 84 auf und wird dadurch angehoben, was zu einem Aufstellen der Aufstellhebel 70, 76 führt. Hierbei ist der Lagerzapfen 90 translatorisch in der durch die Nut 96 gebildeten Führung geführt. Die lichte Weite der Nut 96 ist so bemessen, dass unter Berücksichtigung der Form des Lagerzapfens 90 und des Aufstellwinkels des ersten Aufstellhebels 70 der Lagerzapfen 90 translatorisch in der durch die Nut 96 gebildeten Führung geführt ist, ohne zu klemmen.

The operation of the locking means is as follows:

• As above based on Fig. 7B described, runs during the adjustment of the second setting lever 76 remote from the end of the first raising lever 70 on the lifting guide 84 and is thereby raised, which leads to a setting up the set-up lever 70, 76. Here, the bearing pin 90 is guided translationally in the guide formed by the groove 96. The light Width of the groove 96 is dimensioned so that, taking into account the shape of the bearing pin 90 and the installation angle of the first setting lever 70 of the bearing pin 90 is translationally guided in the guide formed by the groove 96 without jamming.

At the end of the second kinematic phase (see the above description with reference to FIG Fig. 7C and Fig. 11C ) runs the second Aufstellhebel 76 remote from the free end of the first setting lever 70 on the stop member 80 formed on the stop 78, so that a further translational movement of the set-up lever assembly 86 is prevented.

During the subsequent third kinematic phase of the first raising lever 70 performs only an erection movement by being pivoted about the first pivot axis 72. Due to the formation of the bearing pin 90 and the bearing recess 98 of the bearing pin 92 locks in a further setting up of the first dispensing lever 70 on the bearing recess 98 such that it is secured against translational movement, at the same time a further raising movement of the first raising lever 70 is allowed.

By means of the locking means it is ensured that the raising lever arrangement 68 uniformly lowers in the event of a return from a maximally adjusted position in the direction of the unadjusted position. The provision takes place in such a way that the first setting lever 70 pivots back in the direction of the unadjusted position. Due to the locking means, up to a certain set-up position of the first raising lever 70, only one rotary or pivoting movement is permitted. In a predetermined Aufstellage lifts the lock, so that the bearing pin 90 thereafter translationally in the groove 96 moves away in the direction of the stop 78.

Without the locking means, there would be a risk that the first set-up lever will immediately move translationally in the event of a return, and subsequently a sudden lowering will occur, which is undesirable.

Based on FIG. 15 to 23 An exemplary embodiment of a retrofit kit according to the invention of an electromotive adjusting device for a support device for supporting a padding of a sitting and / or lying furniture, in particular a mattress of a bed, is explained in more detail below.

As an electric motor drive the retrofit kit is a drive unit 18 according to the FIG. 1 to 14 provided, which is adapted to exert on the traction cables of Bowden cables or the traction cable at least one Bowden cable a pulling action and thereby to adjust components relative to each other. For reasons of clarity, the drive unit 18 in the FIG. 15 to 23 however omitted.

In FIG. 15 an auxiliary frame 100 of a retrofit kit according to the invention of an electromotive adjusting device is shown, which has two about a horizontal pivot axis 102 relative to each other pivotable frame parts 104, 106.

The frame part 104 has two transverse to the longitudinal direction of the subframe 100 spaced apart longitudinal beams 108, 108 '. The frame part 106 is constructed accordingly and has laterally spaced apart longitudinal beams 110, 110 '. The longitudinal beams 108, 108 ', 110, 110' are formed in the illustrated embodiment by C-profile rails. At their side facing the padding when using the retrofit kit, the frame parts 104, 106 respectively a plurality of spring elements, which are formed in this embodiment by resilient slats, of which in the drawing only two slats by the reference numerals 112, 114 are provided. FIG. 15 shows the subframe 100 in an initial position of the adjustment, in which the frame parts 104, 106 span with each other a horizontal support plane.

FIG. 16 shows the subframe 100 in an end position of the adjustment, in which the frame parts 104, 106, however, are pivoted relative to each other and arranged at an angle to each other.

FIG. 17 shows a detail FIG. 16 in the region of a pivot joint 116, via which the frame parts 104, 106 are pivotally connected to one another. The pivot joint 116 connects the longitudinal spar 108 'of the frame part 104 with the longitudinal spar 110' of the frame part 106. The connection of the longitudinal spar 108 of the frame part 104 with the longitudinal spar 110 of the frame part 106 is designed accordingly and will therefore not be explained in detail.

FIG. 18 shows in opposite FIG. 17 enlarged scale, the pivot joint 116, wherein in particular it can be seen that the longitudinal spar 108 'is formed by a C-profile rail.

To explain the adjustment of the pivot joint 116, which, taken independently of the retrofit kit according to the invention has an independent inventive meaning and is also suitable for the pivoting adjustment of other components, in particular furniture components, is below FIG. 19 Referenced.

As an adjusting member for pivoting the frame parts 104, 106 relative to each other in this embodiment, a lever designed as a raising lever 118 is provided, one end of which is rotatably connected about a pivot 120 with a two-armed lever 122. The pivot bearing 120 remote from the end of the pivot lever is loosely based on the bottom of in FIG. 19 not shown profiled rail.

At the end facing away from the pivot bearing 120 of the pivot lever 118, with which the pivot lever is supported on the bottom of the rail, a pull cable of a Bowden cable is fixed in tension, the in FIG. 19 at the reference numeral 124 is indicated.

A first lever arm 126 of the two-armed lever 122 is pivotally connected eccentrically to the pivot axis 102 with the longitudinal spar 110 'of the frame part 106. The second lever arm 128 of the two-armed lever 122 is guided by means of a linear guide on the other frame part 104. The linear guide has a carriage 130 which is captured in the C-profile of the longitudinal spar 108 'and slidably guided therewith.

For adjusting the frame parts 104, 106 relative to each other, the drive unit exerts a pulling force on the traction cable 124 of the Bowden cable in the direction of an arrow 132, so that the pivot lever 118 pivots on the base of the C-profile of the longitudinal spar 108 'supporting around the pivot bearing 120 and gets up. As a result, the two-armed lever 122 is raised, wherein the carriage 130 slides in the C-profile of the longitudinal spar 108 'in the direction of the arrow 132 and the longitudinal spar 110' and thus the frame member 106 about the pivot axis 102 in FIG. 19 is pivoted counterclockwise.

FIG. 20 shows the pivot joint 116 according to FIG. 19 with the carriage 130 omitted.

The end position of the adjusting movement of the frame parts 104, 106 relative to each other is in FIG. 16 shown.

FIG. 21 shows a combination of a subframe 100 according to the invention with a support means 134 in the form of a slatted frame. Here, the subframe 100 is placed on the slatted frame 134 and thus arranged between the slatted frame 134 and a mattress, not shown in the drawing. In this case, the subframe 100 is oriented in the longitudinal direction of the slatted frame 104 so that the frame part 110 is in the region of the upper body of a person resting on the mattress, pivoting the frame part 106 relative to the frame part 104 thus raising the mattress in the area of the upper body of the person leads. Out FIG. 21 It can be seen that the subframe extends in the longitudinal direction of the slatted base 134 only over part of the slatted frame 134. As a result, an electromotive adjustability is realized in the region of the upper body of a person resting on the slatted frame 134 with the auxiliary frame 104 resting on it, the auxiliary frame 100 being of compact design.

FIG. 22 shows the subframe 100 in a maximum adjustment position in which the frame parts 104, 106 are maximally adjusted to each other.

Out FIG. 23 it can be seen that the subframe 104 has only a small height and thus can be easily placed between the slatted frame and the mattress, without this interfering in any way.

The invention makes it possible in a simple way to retrofit not or not electromotive adjustable slatted frames or other support means with an electromotive adjusting device.
