Description

The invention relates to a lying surface with inclination adjusters according to the preamble of claim 1.

The term a lying surface is understood to mean all lying surfaces of beds, upholstered furniture, sofa beds and the like, including seating and garden furniture.

The invention is independent of whether the bed is provided with slats and is designed as a slatted frame, or whether it is formed without slats as a tensioned surface of any kind.

If in the following description of a lying surface in the training as a bed frame or slatted is mentioned, this is not to be understood as limiting the present invention. This is only for better comparability with the prior art.

With the subject of DE 2 221 825 A1 has become known an apparatus for adjusting of pivotable bed frame parts, in which two lateral tilt adjuster are provided, for example, to pivot the one frame side part relative to the other frame side part. Disadvantage is that always the synchronism of two parallel and opposite tilt adjusters is required.

If, however, during the adjusting movement to the twisting of the head part to the foot part, it may happen that the tilt adjuster working with latching steps on one side, but not on the other side. This requires multiple actuation of the inclination adjuster.

With increasing width of the bed frames a synchronism between parallel and equal width adjacent adjacently arranged inclination adjusters is becoming increasingly difficult to realize, so experience requires several attempts to adjust a pivotally arranged on bed frame headboard tilted to the base frame, and to ensure that both inclination adjuster synchronously and evenly rest.

The same disadvantage is incidentally also in the DE 75 37 346 U1 , which also shows a mattress frame with hinged frame parts.

In the DE 7 201 996 U1 there is the further disadvantage that the locking positions of the latching bolt used for the locking device are spring loaded, which is associated with the disadvantage that the spring load is not the same at different inclinations of the adjustable parts and that the spring can break and then fails the locking device.

The invention is therefore based on the object, a reclining surface with inclination adjusters of the type mentioned in such a way that the inclination adjustment is reliably and reliably made possible at different tilt adjustable segments even with large width of the segments.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

Feature of the invention is that now the respective inclination adjuster according to the invention is arranged approximately centrally on the lying surface and that the inclination adjuster torsionally stiff consists of an outer profiled outer tube, in the inner profile of the profile of the outer tube adapted insertion part is slidably disposed, and between the outer tube and the Insertion part is arranged a locking device.

With the given technical teaching, there is the advantage that the respective inclination adjuster according to the invention is arranged centrally between the tilt-adjustable segments of the lying surface, and therefore can be dispensed with mutually parallel and adjustable inclination adjuster.

This has the advantage that an inclination setting always succeeds evenly with respect to an angled portion to another segment part of the bed, without having to pay attention to a synchronous operation of two mutually parallel, arranged on the same width tilt adjusters.

Due to the formation of a profiled outer tube, in which a same profiled insertion part is mounted longitudinally displaceable with little play, there is the advantage that a particularly torsionally rigid, high loads transmitting tilt adjuster is realized, which now ensures that the mutually bendable segment parts of the lying surface straight are guided to each other, and a bending or warping of these mutually angled, lying surface side segment parts is prevented by the dimensional stability of the tilt adjuster. It is therefore proposed a protected against twisting longitudinal guide of the two intermeshing profile tubes.

In a preferred embodiment of the invention, it is provided that the outer tube of the tilt adjuster is designed as a closed rectangular or square tube and that the insertion part is preferably formed as a plastic part, which is accommodated with little play longitudinally displaceable in the profile of the outer tube and there twisting and twisting -sured.

Between the outer tube and the insertion part is a known locking device, which consists of a slotted guide with at least one latchable therein latching bolt.

Instead of such a locking device consisting of locking device also other locking devices may be used, such as a clamping device, in which it succeeds to set a the outer tube and the insertion part passing through clamping screw so that the displacement position of the guided in the outer tube insertion part fixed to a particular position can be.

Such a clamping screw can be structurally and kinematically realized also electromagnetically or connected to a clamping device, such as an eccentric clamping head or a wedge clamping head.

It is important that a dimensionally stable outer tube is provided with a profile adapted to the outer tube insertion part, so that the inclination adjuster invention also serves as a straight guide between wide inclination segments of the bed, and only one single inclination between the segment-like angled parts of the lying surface is present. The central tilt adjuster therefore acts as centering for the respective bendable parts of the lying surface.

According to the installation position of the inclination adjuster, it may be provided that the slotted guide according to the invention is arranged obliquely in the outer tube and the associated insertion part to always ensure that the latching in the slotted guide locking bolt gravity position finds its locking position and its release position.

Thus, a further advantage of the invention is that it dispenses with springs for spring preload of the locking bolt and the locking pin is guided only gravity loaded in the slide guide to ensure a particularly reliable locking even with prolonged use. A leading to the failure of the detent spring break must therefore no longer be feared.

The further advantage of the invention is that the tilt adjuster according to the invention can be exchanged modularly against adjusting motors, because the length of the inclination adjuster corresponds to the length of motor drives and the hinge points on the inclination adjuster according to the invention correspond to the articulation points on the associated motor adjusters, so that a modular exchange between electromotive drives and a tilt adjuster is readily possible. It is therefore a common assembly platform.

In a preferred embodiment of the invention, the lying surface is formed of a total of two mutually tilt-adjustable tilting parts, namely a front tilting part and a rear tilting part.

Each tilting part is still segmented in itself, and the front tilting part consists for example of a head part, which is connected via a horizontal pivot point pivotally connected to the back part, which back part is pivotally received end to a common base frame.

The same illustration applies to the rear tilting part, which in turn is segmented and consists of a pivotally arranged on one side of the round frame thigh part, which is connected at the opposite end via a horizontal hinge point with the adjoining pivoting lower leg part.

All segment parts are pivotally connected to each other via associated support lever and intermediate lever and mutually supported, so that a total of four existing tilt adjusters a total of four different segment parts of the bed can be set independently reliable.

The mechanical tilt adjusters have a particularly long life and ensure high load transfer, because they are durable with respect to acting shear and torsional forces.

The material of the outer tube is preferably formed as a metal material or highly durable plastic material, while the guided in the outer tube insertion part is preferably formed as a lightweight plastic part.

Preferably, the outer tube is made of a light metal alloy, such as an aluminum profile, in the inner profile of an insertion part is slidably and latchably arranged.

It can also be provided that the outer tube itself consists of a profiled aluminum extruded profile, which is preferably formed closed. In this extruded profile, the insertion part is longitudinally displaceable torsionsgesichert and torsionally stiff longitudinally.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular those shown in the drawings Spatial training, are claimed as essential to the invention, as far as they are new individually or in combination over the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

Perspective view of a lying surface

In FIG. 1 a multi-segmented lying surface is shown with a base frame 1, which consists essentially of a front tilting part 2 and a rear tilting part 7 arranged at a distance therefrom.

The front tilting part 2 is segmented in and consists of a head part 3, which is articulated via a horizontal hinge point 5 pivotally mounted on the free front end of a back part 4, which in turn is pivotally mounted with the horizontal hinge point 6 on the base frame 1.

The same illustration also applies to the rear tilting part 7, which in turn consists of two mutually pivotable segments, namely a thigh part 8 which is pivotally mounted on the base frame 1 via a horizontal hinge point 72 and with an upper hinge point 10 with the free end of the Lower part 9 is pivotally connected.

The said parts 3, 4, 8, 9 are independently pivotable and adjustable in their inclination to the base frame 1.

The adjustment of the head part 3 to the back part 4 via a first inclination adjuster 14, which attaches via a horizontal hinge point 15 at the upper part of the head part 3 pivotally and in the direction of arrow 17 and in the opposite direction is formed longitudinally displaceable and latched.

It engages with its lower end to a horizontal hinge point 16 and is connected via a support plate with the upper end of the back part 4 pivotally connected via the hinge point 16.

When you pull or insert the tilt adjuster 14 in the direction of arrow 17 or in the opposite direction thus the head part 3 is adjusted in the direction of arrows 18 tilt adjustable to the back part 4 and is then locked below.

The inclination adjustment of the back part 4 is effected in that at the upper end of the back part 4, a support lever 11 is pivotally received in a horizontal hinge point 12 which forms a hinge point 21 at its other end, which is fixed to a stabilizing plate 19.

Rotationally fixed in the hinge point 21, an intermediate lever 20 is fixed, the other end is in turn received in a hinge point 22, on which pivotally engages the one part of a second tilt adjuster 24. This in turn is longitudinally adjustable and lockable in the direction of arrow 25 and in the opposite direction.

The rear end of the inclination adjuster 24 is formed as a claw 27 which pivotally surrounds a holding tube 26 connected to the stabilizing plate 19.

The holding tube 26 is also encompassed on the opposite side by a claw 28, which is part of the third tilt adjuster 34.

This is formed longitudinally displaceable and latchable in the direction of arrows 29 and in the opposite direction and engages with its other end to a horizontal hinge point 30, which is formed in the stabilizing plate 19.

In this hinge point 30 engages one end of an intermediate lever 31, the other end is received in the pivot point 32 which is rotatably connected to a support lever 33. The opposite end of the support lever 33 is pivotally received at the pivot point 35 at the upper end of the thigh part 8.

There is a fourth tilt adjuster 44 is present, which also surrounds the pivot point 32 with a claw, not shown, where also in a manner not shown a holding tube is arranged.

This is adjustable in length in the arrow directions 37 and engages with its other end in a hinge point 38 on the stabilizing plate 19, in which at the same time the intermediate lever 39 is pivotally received, which is rotatably connected to the support lever 36. The pivoting of the support lever 36 takes place in the hinge point 40 on the stabilizing plate 19th

The free end of the support lever 36 is received in a hinge point 41 at the free rear end of the lower leg part 9.

In this way, by the length adjustability of each of the four inclination adjusters 14, 24, 34, 44, an individual inclination adjustment of all said segment parts, namely the head part 3, the back part 4, the thigh part 8 and the lower leg part 9, possible.

It is particularly advantageous that the inclination adjusters 14, 24, 34, 44 are installed below the base frame 1 and thus are concealed, so that they take up no space and no height.

Thus, a small overall height at stable pivotal mounting of the individual, pivotally mounted to each other segment parts 3, 4, 8, 9 achieved because the inclination adjuster 14, 24, 34, 44 in torsion resistant and centrally in each case in the lying surface side part 3, 4, 8, 9 are arranged so that they act as a torsionally rigid straight guide for these parts 3, 4, 8, 9. It therefore does not require parallel to each other, arranged on the same width inclination adjuster 14, 24, 34, 44, because these are each arranged only centrally. Thus, a synchronization of different locking devices is no longer necessary, which is considered disadvantageous in the prior art.

FIG. 2 shows a section of the front tilting part 2, where it can be seen that the lying surface can also be equipped with spring elements.

In the illustrated embodiment, supporting elements 46 are present, which each form a lath receptacle 42 for the slats of a slatted frame at the upper end. The lath receptacles 42 are each in pairs and are connected to spring elements 43, which in turn are accommodated in a height adjustment device 45.

In this way, each pair of existing lath receptacles 42 perpendicular to the plane of the respective segment part 3, 4, 8, 9 are formed adjustable in height and lockable.

The invention is not limited to the arrangement of such support members 46 for the slats of a slatted base. It is also possible to provide simple non-height-adjustable slats or also a textile covering or only panels which form the lying-surface-side parts 3, 4, 8, 9.

FIG. 2 also shows the locking guide between the outer tube 47 and the insertion part 48th

After all inclination adjusters 14, 24, 34, 44 are the same design, the explanation of the in FIG. 2 shown tilt adjuster 24 for all other versions. It is important that longitudinally displaceable in the inner profile of an outer tube 47, an insertion part 48 is provided, which is thus guided in the arrow directions 25 displaceable in the outer tube 47.

A control recess 49 is provided in the outer tube 47, which is associated with an associated locking guide in the insertion part 48. There is also a slotted guide 50 and a locking pin 51, the gravity-loaded depending on the shift position of the insertion part 48 in the outer tube 47 engages at a certain locking position of the guide slot 50 or lifted out of this locking tooth and can be brought into a different locking position.

FIG. 2 shows as an example that a total of four detent positions are present, to which the invention is not limited. There may also be more or less detent positions.

The FIG. 3 shows in relation to the other embodiments of the inclination adjuster 14, 24, 34, 44 a modified embodiment in which it can be seen that the insertion part 48 a cranked condyle 73a is arranged, which increases via an angled portion 46 at a distance 58 is formed above the outer tube 47. The cranked condyle 73a is connected to an angle reinforcement 59 for support so as to ensure a high load transfer from the cranked condyle 73a to the insertion part 48. The angle reinforcement 59 engages in a longitudinal slot 60 on the side of the outer tube 47, and thus it is ensured that the condyle 73 a can be inserted as closely as possible into the outer tube 47 in the longitudinal direction.

As shown, the pivot bearing 57 is arranged elevated in the condyle 73 a and has a distance 58 to the underside of the outer tube 47th

Instead of the embodiment of the cranked condyle 73a shown here, other shapes of the condyle may be provided, such as a Z or a U-shape.

The FIG. 4 shows another embodiment of a tilt adjuster, which is referred to as a basic shape, where it can be seen that the insertion part 48 in extension of its longitudinal axis, a joint head 73 is formed, which forms the pivot bearing 57.

For better displaceability of the insertion part 48 in the profile of the outer tube 47, one or more longitudinally aligned guide ribs 61 can be formed on the insertion part 48.

The FIGS. 3 and 4 also show various embodiments of arranged on the outer tube rod ends, wherein the in FIG. 3 shown condyle consists of two, formed by flanges 54 joint bearings 52 which are pierced by a common transverse bore 53.

The condyle after FIG. 4 is formed as a claw 27 having a central, outwardly open recess 55, so that such a claw on the in the drawing FIG. 1 shown holding tube pushed and snapped there and is pivotally mounted on this holding tube 26. It therefore requires no Schraubbefestigung.

Incidentally, the invention is related to the FIGS. 3 and 4 not limited to that on the right side of the outer tube 47 each have an outer tube side condyle is arranged. It can also be provided that two mutually displaceable insertion parts 48 in a single Outer tube 47 are arranged, and that each insertion part is assigned an associated slotted guide with locking device.

Thus, the outer tube 47 is merely to be referred to as the center tube, on each of which two oppositely and separately latchable insertion parts 48 are provided at each end.

The FIG. 5 shows the exploded view of a tilt adjuster 14, 24, 34, 44 after FIG. 4 , where it can be seen that the profile shape of the insertion part 48 of the profile shape of the outer tube 47 is adjusted. Furthermore, it can be seen that the insertion part-side longitudinal recess 65 substantially consists of a smooth running, approximately in the direction of the longitudinal axis of the insertion part 48 aligned control surface 66, the recessed merges into subsequent plurality of latching steps 67, which are formed as half-open locking grooves, the form an abutment for a locking bolt 51 engaging there detent.

The latching pin 51 is slidably mounted in a control recess 49 in the outer tube 47, and in the control recess 49, a slotted guide 50 is formed, which consists essentially of a return position 68 and a latching position 69.

There is the locking pin 51 in the detent position 69 and it is the insertion part 48 pulled out in the direction of arrow 75 from the outer tube 47, so that the stop 74 takes the locking pin 51 via the slide guide from position 69 with, moves it over the slope 76 away and brings him in the return position 68, which brings the locking pin on the just formed control surface 66.

Starting from this parking position, both the displacement of the insertion part 48 in the opposite direction to the arrow 75, the stop 77 can take the resting on the control surface 66 locking pin 51 and brings him into the locking position 69, wherein it then falls into the first latching step 67.

After the locking pin 51 in the first latching step 67 (in FIG. 5 the leftmost latching step) has fallen into it, this latching step 67 can either be occupied, or by re-pulling the insertion part 48 in the direction of arrow 75, another latching 67 found (right of the leftmost detent step) and anchored there the locking pin.

In this way, a latching length adjustment of the insertion part 48 in the outer tube 47 at any locking position of the latching steps 67 is possible.

In the illustrated embodiment, the locking pin 51 is formed as a round bolt, the left side carries a head of increased diameter and the right side is provided with a washer 62, and is secured against pulling out with a locking ring 63.

The Figures 5 and 6 show further that the outer tube side condyle is connected by screws 64 with the end face of the outer tube.

The condyle can either as a claw 27 or as a clevis with a pivot bearing 52 according to FIG. 6 be educated.

In contrast to FIG. 5 show the FIG. 6 a locking device having only two latching steps 67, while the representation after FIG. 5 a total of six detent steps forms.

The FIGS. 7 to 9 show various embodiments of a locking bolt 51. In FIG. 7 is a locking pin 51 according to Figures 5 and 6 shown. It consists essentially of a head 70 and a molded-on bolt arranged thereon and is secured on one side by means of the shim 62 and the retaining ring 63 against withdrawal.

The locking ring 63 engages in an associated annular groove at the free end of the locking bolt 51 a.

The FIG. 8 shows in contrast to FIG. 7 in that two different locking bolts 51 a, 51 b can also be present, which are formed separately from one another. Each locking pin 51 a, 51 b is then assigned a link guide.

The FIG. 9 shows in contrast that it is sufficient to use only a single locking pin 51 c, which is associated with a single link guide.

The FIGS. 10 to 14 show various embodiments of profile shapes of the outer tube 47 in comparison to the insertion part 48 arranged there displaceably.

The FIG. 10 shows a rhombic shape, that is, a rectangular or square shape, which is turned upside down while the FIG. 11 an oval shape that FIG. 12 a rooftop shape and the FIG. 13 show an outwardly open U-shape of the outer tube 47.

In order to avoid falling out of the insertion part 48 shown there, end stops 71 are provided.

The same applies to the U-shape after FIG. 14 , where it can be seen that in a downwardly open U of the outer tube 47, an insertion part 48 is slidably mounted and is secured against falling out by frontal attacks. Instead of a closed profile, therefore, a semi-open profile can be used.

The insertion part 48 is shown in each case as a material-solid part. The invention is not limited thereto. It can also be profiled as any shaped be formed extruded plastic or aluminum extruded profile and guided longitudinally displaceable in accordance with suitable, inner guide ribs of the outer tube.

In the embodiments of the FIGS. 10 to 14 is characteristic that at the opposite, vertical side surfaces of the respective outer tube 47, the possibility must be created to arrange there a slide guide, as shown with the slide guide 50 in conjunction with the associated control recess 49 and in the preceding drawings.

For reasons of simplification, the control recess 49 in connection with the slotted guide 50 does not follow in the drawing examples FIGS. 10 to 14 located.

It is also possible to divide the locking pin 51 by, for example, the locking pin 51 after FIG. 7 two-piece forms and arranged on the fixed to the one part of the locking bolt head 70 an opposite head, which is screwed into the material of the locking bolt by means of a threaded hole and a screw.

FIG. 15a to FIG. 15c shows how a locking plug 78 can be positioned in the insertion part 48. The introduction of the locking stopper 78 serves to limit the number of half-open latching steps 67, which adjoin the control surface 66 and form an abutment for a locking latch engaging there.

Such a stopper 78 consists of a trapezoidal base body 81, with a sloping in the direction of the guided in the longitudinal recess 65 locking pin oblique surface 79 and adapted to the profile shape of the latching step 67 locking tooth 80, located at the bottom of the main body 81st followed. The inclined surface 79 enables improved guidance of the latching pin coming into contact with the inclined surface.

The main body 81 of the locking stopper 78 corresponds in height approximately to the width of the longitudinal recess 65 in the region of the control surface 66, so that a latching steps 67 positively inserted latching plug 78, the longitudinal recess in the area above the latching level completely fills and thus can not tilt sideways.

In the example shown FIG. 15b is the locking plug 78 in the fifth detent stage, starting from the control surface 66, inserted. A in the thus shortened longitudinal recess 65 guided locking pin can now be introduced into the remaining four locking steps between control surface 66 and inclined surface 79 of the locking stopper.

In a entrainment of resting on the control surface 66 locking bolt 51 through the outer tube, not shown in the direction of Ratsstopfens, are the locking pin after FIG. 15b now four instead of five Raststufen 67 available. In this way, a latching length adjustment of the insertion part 48 in the outer tube 47 is only possible to a limited extent.

In a change in position of the locking stopper 78 in the third last stop step 67 in front of the control surface according to FIG. 15c , the possible length adjustment is limited to two locking steps.

By limiting the length adjustment, the same insertion part can be installed in different areas of the base frame, where a different maximum length adjustment is desired. By producing only one insertion part for different installation position thus the tool costs can be reduced.

FIG. 16 shows a slightly modified embodiment, wherein a holding tube between the second and the third inclination adjuster is dispensed with. In FIG. 16 Also, a multi-segmented lying surface is shown with a base frame 1, which consists essentially of a front tilting part 2 and a rear tilting part 7 arranged at a distance therefrom.

The front tilting part 2 is segmented in and consists of a head part 3, which is articulated via a horizontal hinge point 5 pivotally mounted on the free front end of a back part 4, which in turn is pivotally mounted with the horizontal hinge point 6 on the base frame 1.

The same illustration also applies to the rear tilting part 7, which in turn consists of two mutually pivotable segments, namely a thigh part 8 which is pivotally mounted on the base frame 1 via a horizontal hinge point 72 and with an upper hinge point 10 with the free end of the Lower part 9 is pivotally connected.

The said parts 3, 4, 8, 9 are independently pivotable and adjustable in their inclination to the base frame 1.

The adjustment of the head part 3 to the back part 4 via a first inclination adjuster 14, which attaches via a horizontal hinge point 15 at the upper part of the head part 3 pivotally and in the direction of arrow 17 and in the opposite direction is formed longitudinally displaceable and latched.

It engages with its lower end to a horizontal hinge point 16 and is connected via a support plate with the upper end of the back part 4 pivotally connected via the hinge point 16.

When pulling or pushing the inclination adjuster 14 in the direction of arrow 17 or in the opposite direction thus the head part 3 in the arrow directions 18th tiltable adjusted to the back part 4 and is then locked below.

The inclination adjustment of the back part 4 is effected in that at the upper end of the back part 4, a support lever 11 is pivotally received in a horizontal hinge point 12 which forms a hinge point 21 at its other end, which is fixed to a stabilizing plate 19. The hinge point 21 is formed by a holding tube 82, which extends in the transverse direction through the base frame 1.

Rotationally fixed in the hinge point 21, an intermediate lever 20 is fixed, the other end is in turn received in a hinge point 22, on which pivotally engages the one part of a second tilt adjuster 24. This in turn is longitudinally adjustable and lockable in the direction of arrow 25 and in the opposite direction.

The rear end of the inclination adjuster 24 is connected via a claw to the holding tube 83, wherein the claw pivotally surrounds the holding tube 83.

The third tilt adjuster 34 is longitudinally displaceable and latchable in the direction of the arrows 29 and in the opposite direction and engages with its other end to a horizontal pivot point 30 which is formed in the stabilizing plate 19. The rear end of the inclination adjuster 34 is connected via a claw with the holding tube 82, wherein the claw pivotally surrounds the holding tube 82.

In the pivot point 30 engages one end of an intermediate lever 31, the other end is received in the pivot point 32 which is rotatably connected to a support lever 33. The opposite end of the support lever 33 is pivotally received at the pivot point 35 at the upper end of the thigh part 8.

There is a fourth tilt adjuster 44 is present, which also surrounds the hinge point 32 (holding tube 83) with a claw, not shown.

This is adjustable in length in the arrow directions 37 and engages with its other end in a hinge point 38 on the stabilizing plate 19, in which at the same time the intermediate lever 39 is pivotally received, which is rotatably connected to the support lever 36. The pivoting of the support lever 36 takes place in the hinge point 40 on the stabilizing plate 19th

The free end of the support lever 36 is received in a hinge point 41 at the free rear end of the lower leg part 9.

In this way, by the length adjustability of each of the four inclination adjusters 14, 24, 34, 44, an individual inclination adjustment of all said segment parts, namely the head part 3, the back part 4, the thigh part 8 and the lower leg part 9, possible.

It is particularly advantageous that the inclination adjusters 14, 24, 34, 44 are installed below the base frame 1 and thus are concealed, so that they take up no space and no height.

Thus, a small overall height at stable pivotal mounting of the individual, pivotally mounted to each other segment parts 3, 4, 8, 9 achieved because the inclination adjuster 14, 24, 34, 44 in torsion resistant and centrally in each case in the lying surface side part 3, 4, 8, 9 are arranged so that they act as a torsionally rigid straight guide for these parts 3, 4, 8, 9. It therefore does not require parallel to each other, arranged on the same width inclination adjuster 14, 24, 34, 44, because these are each arranged only centrally. Thus, a synchronization of different locking devices is no longer necessary, which is considered disadvantageous in the prior art.

FIG. 17 shows a perspective view of FIG. 16 , wherein due to the better representability of the inclination adjuster 14 and the inclination adjuster 44 are not shown.

The front tilting part 2 is segmented in itself and consists of a head part 3, which is articulated via a horizontal pivot point 5 pivotally connected to the free front end of a back part 4, which in turn is pivotally connected to the base frame 1.

The same illustration also applies to the rear tilting part 7, which in turn consists of two mutually pivotable segments, namely a thigh part 8, which is pivotally mounted on the base frame 1 via a horizontal hinge point.

The said parts 3, 4, 8 are independently pivotable and adjustable in their inclination to the base frame 1.

The inclination adjustment of the back part 4 is effected in that at the upper end of the back part 4, a support lever 11 is pivotally received in a horizontal hinge point 12 which forms a hinge point 21 at its other end, which is fixed to a stabilizing plate 19. The hinge point 21 is formed by a holding tube 82, which extends in the transverse direction through the base frame 1.

Rotationally fixed to the holding tube 82, an intermediate lever 20 is fixed, the other end is in turn received in a hinge point on which pivotally engages the one part of a second tilt adjuster 24.

The rear end of the inclination adjuster 24 is connected via a claw 84 with the holding tube 83, wherein the claw 83, the holding tube 83 pivotally engages around.

The third tilt adjuster 34 is longitudinally displaceable and latchable in the direction of the arrows 29 and in the opposite direction and engages with its other end to a horizontal pivot point 30 which is formed in the stabilizing plate 19. The rear end of the inclination adjuster 34 is connected via a claw with the holding tube 82, wherein the claw pivotally surrounds the holding tube 82.

In the pivot point 30 engages the one end of an intermediate lever 31, the other end in the hinge point 32 (holding tube 83) is received, which is rotatably connected to a support lever 33. The opposite end of the support lever 33 is pivotally received at the pivot point 35 at the upper end of the thigh part 8.

It is particularly advantageous that the inclination adjusters 24 and 34 are installed below the base frame 1 and thus are concealed, so that they take up no space and no height.
