Description

The invention relates to a chair, preferably armchair or sofa, with a base body, preferably backrest, seat or frame and a pivotable relative to the main body functional part, preferably headboard, footboard or armrest, at least one pivot fitting for adjusting the functional part relative to the base body and a, in particular separate Hubsteller, for locking the functional part relative to the base body, wherein the Hubsteller has a guide and a sliding relative to the guide tab, wherein the Hubsteller of a adjustment of the functional part relative to the base body in a loading direction in several positions positively and / or clamping blocking setting position in an adjustment of the functional part relative to the base body in the loading direction from at least one position releasing reset position is adjustable, and wherein the functional part is carried by a pivot lever.

Furthermore, the invention relates to a chair, preferably armchair or sofa, with a base body, preferably backrest, seat or frame and a pivotable relative to the main body functional part, preferably headboard, foot or armrest, at least one pivot fitting for adjusting the functional part relative to the base body and a locking joint for locking the functional part relative to the base body in a locking position of the locking joint, wherein the functional part is supported by a pivot lever and connected via a lever to the main body, wherein the pivot lever and the lever are connected via the pivot axis forming a detent joint and wherein the locking joint a Having a toothed ring and a ratchet engaged in the ratchet position in the ratchet position,

Seating furniture, for instance in the form of sofas or armchairs, with functional parts pivotable relative to a base body are known in various configurations and enable the user of the chair to assume a comfortable sitting and / or reclining position. As functional parts are in particular headboards, which are also referred to as headrests, footboards or armrests in question. As a basic body here all the body of the chair into consideration, against which the functional part is adjusted. In particular, in this case come as a base body in question, which are not adjusted even though this is not mandatory. The main body can be, for example, a backrest, a seat or a frame in which the seat and / or the backrest can be accommodated. Instead of a frame but also comes in a chassis in question, which can form a frame together with attachments in the form of side panels.

The user of the chair can lean his head comfortably against the headboard, put his feet or legs comfortably on the footboard or put his arms comfortably on the armrests. A possible motorized adjustment of the headboard relative to the backrest further enhances the comfort of the user of the chair. In addition, the functional part can be held in any position.

To adjust the functional part, the seating on so-called swivel fittings, which allow a targeted adjustment of the functional part relative to the main body. The swivel fittings have at least one pivot lever which at least partially carries the functional part.

In order to ensure a corresponding adjustability and at the same time a lockability of the functional part in the desired position or in different positions, in some cases so-called lifting plates are used. Hubpers include a guide, such as in the form of a housing, and a tab that can be moved relative to the guide or can be pulled out. Tab and guide are preferably connected substantially linearly connected. In addition, the tab carries a spring-loaded locking element, the as a result of the spring force when pulling the tab in this along the guide provided recordings snaps or can engage. The recordings and the latching element are matched to one another in such a way that after latching in a receptacle, the latch can not be displaced again in the opposite direction along the guide or pushed back into the guide, optionally in the form of a housing. This is prevented by the positive engagement of the locking element in the corresponding receptacle. However, further displacement or extension of the tab can be done easily from the same position. In order to bring the tab back to the starting position, the tab must first be moved to an end position or pulled out. The locking element is blocked so that it can not engage in the recordings when pushing back the tab, such as in the housing. When re-pulling the tab relative to the guide or from the housing, however, the locking element is activated again and thus engages again, at least potentially, one after the other in the recordings.

By blocking a movement of the tab as described above and releasing this movement as required, the lift actuator also blocks the movement of the functional part, preferably in a loading direction. This results in the intended use of the functional part by the user. Due to the coupling of the functional part and the base body with the swivel fitting and the lifting plate, the displacement of the flap relative to the guide of the lifting plate is accompanied by an adjustment of the functional part relative to the base body and vice versa.

In other seating furniture of the type mentioned instead of a Hubstellers a locking joint for locking the functional part relative to the base body is provided in a locking position of the locking joint. The locking joint connects the pivot lever, which carries the functional part, with the adjusting lever via which the pivot lever is connected to the main body. In addition, the locking joint forms an axis of rotation about which the pivot lever and thus the functional part to the adjusting lever can be swiveled, at least in one direction (setting direction). In the other direction, in which the pivot lever is loaded during normal operation (load direction), the pivoting of the pivot lever, however, is at least partially hindered. For this purpose, the locking joint on a sprocket and a locking mechanism, which may be formed for example as a pawl or a series of teeth corresponding to the sprocket may have. In a detent position of the locking joint, the locking mechanism engages in the ring gear and prevents the ring gear can rotate in the direction opposite to the ratchet. In this way, the pivot lever can be held in different positions, depending on where the locking mechanism engages the ring gear.

The locking mechanism can be assigned to the adjusting lever and the ring gear to the pivot lever or vice versa. Are the ratchet and the ring gear firmly connected to the corresponding lever, is prevented by the engagement of locking mechanism and ring gear that the pivot lever is pivoted in the loading direction relative to the actuating lever. In the opposite direction pivoting of the pivot lever to the lever is possible, which is achieved by a corresponding bevel of the teeth of the ring gear and / or a corresponding configuration of the locking mechanism. When swiveling in one direction, the ring gear thus slides on the ratchet, while this is not the case in the opposite direction, in different positions of the pivot lever. In order to move the pivot lever back to the starting position, it must first be pivoted to an end position. Only then is pivoting back of the pivot lever in the starting position possible by a corresponding mechanism.

A disadvantage of the previous seating furniture is required for the swivel fitting space and / or the complexity of the swivel fitting. Therefore, corresponding seating furniture has a corresponding size and / or complexity, which is cumbersome, less appealing and more expensive.

Thus, the present invention has the object, a chair of the aforementioned type and previously described in such a way and further develop that the seating smaller and / or can be constructed easily, without restricting the functionality appreciably.

This object is achieved in a chair according to the preamble of claim 1, characterized in that the functional part is connected via a lever to the base body, that the pivot lever and the lever are pivotable about a pivot axis against each other that the adjusting lever relative to the base body of a lower position in an upper position and back is adjustable, that the pivot lever is connected via a lever connection comprising a handlebar lever and a control lever to the base body, that the handlebar lever relative to the pivot lever and relative to the control lever is pivotable, the control lever pivotally relative to the base body and / or the adjusting lever and that the control lever is connected to the adjusting lever, that the control lever is pivoted when adjusting the control lever from the lower position to the upper position and back against the base body and / or the adjusting lever and so on the handlebar lever pivoting n causes the pivot lever relative to the actuating lever.

This object is achieved in a chair according to the preamble of claim 11, characterized in that the adjusting lever relative to the base body from a lower position to an upper position and back is adjustable, that the pivot lever via a lever connection comprising a handlebar lever and a control lever connected to the main body is that the handlebar lever is pivotable relative to the pivot lever and relative to the control lever, that the control lever is pivotable relative to the base body and / or the adjusting lever and that the control lever is so connected to the adjusting lever, that the control lever when adjusting the adjusting lever from the lower position is pivoted to the upper position and back against the body and / or the lever and so on the Handlebar lever causes a pivoting of the pivot lever relative to the actuating lever.

It is therefore intended that the functional part is held by a pivot lever which is supported for adjusting the functional part via an adjusting lever on the base body, wherein the pivot lever is pivotable relative to the adjusting lever and the adjusting lever can be adjusted relative to the base body. The pivot lever is also connected via a further lever connection with the base body, wherein the lever connection comprises at least one handlebar lever and a control lever. The handlebar lever is pivotally mounted both relative to the pivot lever and with respect to the control lever. In addition, the control lever is pivotable relative to the base body and / or the adjusting lever and connected to the adjusting lever, that the adjusting lever pivots the control lever when the adjusting lever is adjusted in height, in particular pulled out or pushed in relation to the main body.

For this purpose, the control lever may be fixed with the end facing away from the handlebar lever in a manner relative to the base body, that this end can not be moved in the same way by the adjusting lever, as the area connected to the adjusting lever of the pivot lever. However, the control lever does not have to be fixed completely stationary relative to the main body.

The fact that the pivot lever is connected via a lever connection to the base body or supported by a lever on the base body is intended to express that no direct connection between the lever connection or the adjusting lever and the base body must exist. It may be further provided components between the lever connection or the adjusting lever and the base body. This applies in the present case also for other compounds which are described analogously.

The connection between the control lever and the adjusting lever can, in particular in the case where the functional part is a head part and the main body is a backrest is to be formed so that the control lever is pivoted at least one end up when the adjusting lever is moved from the lower position to the upper position. When adjusting the control lever from the upper position to the lower position, the same end of the control lever can be pivoted down. This end may be associated with the handlebar lever and thus this shift depending on the adjustment of the actuating lever up or down, whereby the pivot lever is moved to the pivoted-upper position or in the zurückverschwenkte lower position. The free mobility of the remote from the handlebar lever end of the control lever can be blocked by a connection of this end to the body in any case in relation to the opposite end of the control lever.

The functional part is thus moved when adjusting the same about the height adjustment of the control lever up or down and additionally pivoted back and forth on the simultaneous pivoting of the control lever. The adjustment of the functional part upwards and forwards to the pivoted-on position leads to a stretching of the upholstered section which is bent more strongly in the back-pivoted position of the functional part. This allows an adjustment of the functional part without wrinkling of the pad. A pure pivoting of the functional part from an angled relative to the base body position in a position which is aligned substantially parallel to the base body, would result in the case of padding of base and functional part to a wrinkling of excess in this position padding material. By lowering the functional part during the pivoting thereof in the zurückverschwenkte position cushioning material is provided for bending the pad to the rear, so that the pad does not have to be stretched in this area or stretched.

In the event that the functional part is a foot and the body is a seat, the pivot lever is pivoted upward, while the control lever and the lever are moved forward and vice versa. Then the Namely, preferably mounted in the longitudinal direction or approximately horizontally and not in an approximately vertical direction as for pivoting a head part relative to a backrest. The functional part in the form of a foot part is ultimately preferably moved over the adjusting lever to the front and rear and additionally pivoted about the simultaneous pivoting of the control lever up and down. The adjustment of the functional part upwards and forwards to the pivoted-on position in turn leads to a stretching of the upholstered section which is bent more strongly in the pivoted-back position of the functional part. This allows an adjustment of the functional part without wrinkling of the pad.

In addition, the mechanism for adjusting the functional part comes with relatively few components. The corresponding mechanism can therefore be mounted quickly and inexpensively.

To save components, it is preferred if the handlebar lever is connected directly to the pivot lever and the control lever. This can be done in each case via a pivot connection, so that the link lever is pivotable about a pivot axis with the pivot lever and the control lever. If necessary, but in principle further components can be integrated into the swivel fitting.

In a first preferred embodiment of the seat, the lifting plate on a locking element which cooperates with at least one receptacle, in particular a plurality of receptacles. The plurality of receptacles is then chosen so that the locking element can engage in different positions of the tab with respect to the guide of Hubstellers in each case a recording. The latching element is in particular spring-loaded in order to support a latching in the at least one receptacle. The locking element forms by engaging in a receptacle a latching connection, which blocks the adjustment of the tab relative to the guide or the functional part relative to the base body in one direction, in particular the loading direction positively. With multiple shots, the position of the tab of the Hubstellers in different positions be locked, at least in a direction of displacement of the tab against the guide. From a constructive point of view, it is also preferred if the at least one receptacle in the guide, in particular in the form of a housing, and the at least one latching element are provided on the tab.

Furthermore, the locking element can be deactivated so that the tab can be adjusted without blocking the guide, in particular so that the functional part can be adjusted in the loading direction relative to the base body. The deactivation is effected by moving the tab relative to the guide in an end position. The latching element can then be held in a retracted position, for example, in which the latching element can not engage with the at least one receptacle. In addition, the latching element can be reactivated by moving the tab relative to the guide in another end position, so that the locking element can engage with the at least one receptacle again. In the deactivated position of the locking element, the tab can thus be moved back in a direction in which the displacement of the tab is prevented in the activated position.

It is particularly preferred in terms of functionality, when the Hubsteller has at least one clamping element which is displaceable relative to the tab between a clamping position and an adjustment position. In the clamping position, the clamping element can be received in a clamping gap between the tab and the guide, in particular in the form of a housing, clamping, so that a displacement of the tab against the guide is prevented in one direction. This direction is preferably the direction in which the tab is loaded when the functional part is subjected to a normal load. This can be caused by the application of the head of the user to the headboard, by placing the legs on the footboard or supporting the arms on the armrests. Due to the jamming of the clamping element in the nip is achieved that the functional part in partial deflection not in the direction of a starting position can be reset. In the adjustment, the clamping element is not clamped in the nip. The tab can therefore be moved in a direction opposite to the guide. In the opposite direction, this is only partially possible. Namely, the clamping element passes so far into the nip after a very short adjustment that the clamping element is clamped in the nip and blocked further adjustment of the tab in this direction. The clamping can ultimately achieve a quieter and more accurate adjustment of the functional part relative to the main body.

A structurally simple and at the same time functional design of the Hubstellers is achieved when the nip tapers in one direction and / or when the clamping element is clamped in the clamping position between a tapered end of the tab and the guide. More elaborate designs of the Hubstellers that would be prone to malfunction, it does not need. The nip also tapers counter to the direction in which the clamping of the tab is effected. In addition, it is preferred if the clamping forces are so great that the tab is reliably clamped in the appropriate direction, even in the case of force effects of improper use.

In order to simplify and ensure the displaceability of the clamping element relative to the tab from the adjustment position into the clamping position and back, a clamping carriage may be provided which has the at least one clamping element and is also provided displaceable relative to the tab. The slidable coupling of tab and clamping carriage can be ensured in a simple manner via an opening provided in the tab slot, wherein the clamping carriage engages in the slot.

In order to securely hold the clamping element in the adjustment position and accordingly to allow a free adjustment without blocking, a releasable connection between the tab and the clamping element and / or clamping carriage is provided. The detachable connection can be closed by a separate operation by moving the tab relative to the guide in a connection position clamping and / or detent. In particular, this is done for the sake of simplicity and reliability by a stop of the clamping element and / or the clamping carriage at an end stop.

In this case, the clamping element and / or the clamping carriage rest at least partially frictionally on the guide. If the tab is displaced successively in opposite directions relative to the guide, the clamping element and / or the clamping carriage remains in a position when changing the direction of the tab initially, resulting in a relative displacement of the clamping element and tab. As a result, the at least one clamping element is clamped in the nip or adjusted from a clamped position to a non-clamping position.

In a particularly preferred embodiment of the Hubstellers the tab is substantially continuously adjustable along the guide and / or clamped. Since the jamming blockage of the Hubstellers no recordings required, which must each have a considerable minimum distance between them, the clamping element can be clamped along the entire displacement of Hubstellers in the nip between the tab and guide in principle.

In a first preferred seating comprising a locking joint, the locking mechanism is spring-loaded in the direction of the ring gear. In this way, it is ensured in the detent position that engages the locking mechanism, in particular at different orientations of sprocket to locking or different angular positions of the pivot lever in the sprocket to hinder rotation of the sprocket in the return position or loading direction from the respective position ,

Alternatively or additionally, the ring gear and the ratchet can be disengaged in a pivoting position to the pivot lever relative to the To be able to pivot lever back to the starting position back. It is particularly simple and reliable when the pivot lever must first be brought into an end position, thereby to transfer the locking joint from the detent position to a reset position. Preferably, the locking joint forcibly passes without further action of the user in the reset position. In the reset position, the ratchet is separated from the sprocket, in particular over the entire adjustment path of the pivot lever until the pivot lever has reached the starting position. Then the locking joint also preferably forcibly returns to the locked position. A gradual adjustment of the pivot lever for setting a comfortable position for the user can then be done again without having to worry about accidentally zurückverstellen the pivot lever in the respective positions.

The handling of the swivel fitting can alternatively or additionally be simplified in that the pivot lever and the actuating lever are held against each other in a force-locking manner. This adhesion can be overcome by sufficient forces on the pivot lever in the loading direction. The adhesion should be adjusted so that the swivel fitting can be adjusted by sliding the sprocket and locking in the direction of adjustment. In addition, the frictional connection should be so large that the pivoting of the pivot lever in the return direction is prevented by the engagement of sprocket and locking mechanism. Only when significantly higher forces are used, the adhesion allows overcoming the static friction and an adjustment of the pivot lever in the return direction. So on the one hand accidental Zurückverstellen the pivot lever is avoided and on the other hand prevents damage to the locking joint by excessive force. Corresponding locking joints can be referred to as a locking / clamping joint due to the function described above. In order to enable the provision of the pivot lever despite engagement of ring gear and locking mechanism, it makes sense, when the ring gear and / or the locking mechanism so rotatable relative to the pivot lever and / or the lever is held that in the locking position of the pivot lever is pivotable in a direction opposite to the actuating lever.

In order to adjust the force acting on the locking joint clamping force between the pivot lever and the adjusting lever, which prevents too easy adjustment of the pivot lever relative to the adjusting lever, the locking joint may comprise a clamping device. The clamping device can be designed as a screw connection, for example comprising a screw provided concentrically with the axis of rotation of the latching joint. The pivot lever, the lever and, if necessary, other components can then be easily clamped between the screw head and a nut screwed onto the screw in the desired intensity.

In a further preferred embodiment of the seat, which may have a Hubsteller and / or a locking joint each of the type described above for locking the functional part, the control lever via one end to the base body, via another end to the handlebar lever and between the two ends connected to the lever. Then the control lever can cause a reliable and extensive adjustment of the functional part even with a small overall length. The control lever can be pivoted by the connection with the adjusting lever at the handlebar lever associated end up or down. The handlebar lever can thereby also be adjusted relative to the backrest so as to pivot the pivot lever up or down or front or rear.

It is also structurally simple and reliable, when the control lever and the adjusting lever via a pivot connection, in particular via a hinge, are interconnected. The adjusting lever and the control lever can then form a common pivot axis or axis of rotation.

Alternatively or additionally, the lever connection comprising the link lever and the control lever for simplifying the construction via a pivot connection, in particular via a hinge, engage the pivot lever, wherein the pivot connection for simplicity can define a pivot axis or a rotation axis between the pivot lever and the link lever. It is particularly preferred in this context, when the pivotal connection between the pivot lever and the handlebar lever between the free end of the functional part associated end of the pivot lever on the one hand and a pivotal connection between the rocker arm and the lever on the other hand engages the pivot lever. Thus, the connection between the pivot lever and the lever connection can define a pivot axis which is arranged between the end of the pivot lever assigned to the free end of the functional part and the pivot axis between the pivot lever and the control lever. In this way, a suitable adjustment of the functional part from the rear to the front and back or up and back (depending on the installation position and functional part) allows. It is advantageous for saving space when the lever connection engages near the pivot axis between the pivot lever and the adjusting lever on the pivot lever. It does not require a large distance to transmit a sufficiently large moment on the pivot lever.

The simple adjustability and the stable support of the control lever half of the adjusting lever can be held on a holder on the base body and against the holder at least partially extendable in the vertical direction, preferably telescopic, be. For this purpose, the holder and / or the adjusting lever may be formed as a rail element. For the purpose of displaceability, the holder and the adjusting lever are preferably formed as a rail system. In addition, at least one rail element can be mounted via rollers to reduce frictional forces.

The control lever can be set directly to the support for the lever to simplify the design effort. To be able to compensate for movements when adjusting the functional part, but the control lever can also be set for example via a balance lever on the bracket.

In addition, it is preferred if the tab of Hubstellers are connected to a handlebar lever and the leadership of Hubstellers with the body. The Hubsteller could also be integrated as a lever in the swivel fitting. However, it is preferred for functional reasons and the ease of repair, if the pivot fitting for adjusting the functional part and the Hubsteller for locking the functional part are formed separately. In addition, the tab and / or the guide of Hubstellers may be connected instead of the pivot fitting with the functional part and / or the body.

In the Fig. 1 the inner construction of a seat 1 is shown with a base 2 in the form of a backrest and an adjustable functional part 3 in the form of a head, on the right side of the chair 1 in the form of a chair. The provided on the right side of the chair 1 swivel fitting 4 for adjusting the functional part 3 is provided in the same way mirror image on the left side of the chair 1, not shown.

In addition to the pivot fitting 4, a separate Hubsteller 5 is provided in each case, which is connected to the pivot fitting 4 and prevents the functional part 3 is accidentally pivoted back by the application of the head of the user from a partially pivoted position back into the zurückverschenkte starting position. The Hubsteller 5 comprises a tab 6, which is guided on a guide 7 and relative to the guide 7 is displaceable. At the illustrated and so far preferred seating 1, the guide 7 is formed in the form of a housing from which the tab 6 can be pulled out to the pivot fitting 4 and the functional part 3 of the in the Fig. 1 The tab 6 of the Hubstellers 5 is pivotally connected in the illustrated and so far preferred seating 1 with a handlebar lever 8, while the guide 7 of the lifting actuator 5 relative to the main body. 2 is determined in the form of the backrest.

From the in the Fig. 1 shown zurückverschwenkten position of the functional part 3, the functional part 3 can be adjusted by adjusting by hand upwards in the pivoted position. This is in the Fig. 2 shown. In the pivoted position of the functional part 3, the functional part 3 is not only pivoted forward, but also shifted upwards. This is served in the Fig. 3 closer fitting shown 4.

In the Fig. 3 In addition to the pivot fitting 4 and the main body 2 and the functional part 3 in the back-pivoted position including padding 9 are shown. In the illustration according to Fig. 4 is the functional part 3 in the same chair 1 in the swung-open position. The functional part 3 is supported on the respective side of the seat 1 shown by a pivot lever 10. The pivoting lever 10 has a free end, which in the illustrated preferred seat 1 in the direction of the free end of the functional part 3, or at least assigned to this. With the opposite end of the pivot lever 10 is freely rotatably mounted on a lever 11. The pivotal connection 12 between the pivoting lever 10 and the adjusting lever 11 allows a free and unhindered pivoting of the functional part 3 relative to the adjusting lever 11 over the entire adjustment range of the functional part 3.

The lever 11 of the illustrated and so far preferred seat 1 is configured approximately Z-shaped and with the pivot lever 10 facing away from the end in a Mounted 13 held or held on a holder 13. The holder 13 is fixed to the base body 2. In this case, the lower portion of the actuating lever 11 and the holder 13 of the illustrated and so far preferred seating furniture 3 form a rail system which is designed such that the adjusting lever 11 can be pulled upwards out of the holder 13 and then pushed back down into the holder 13 , About the displacement of the control lever 11, the functional part 3 can ultimately be moved relative to the base body 2 up and down.

The holder 13 is also connected to the guide 7 of the Hubstellers 5, wherein the guide 7 is pivotally hinged to the bracket 13. Alternatively, the guide 7 could be articulated directly on the base body 2, but this connection would be less stable under certain circumstances.

For pivoting the functional part 3 relative to the base body 2 is a lever connection 14 between the pivot lever 10 and the base body 2. This lever connection 14 engages the pivot lever 10 adjacent to the pivotal connection 12 between the pivot lever 10 and the lever 11 in the form of a rotary joint, namely at zurückverschwenktem functional part 3 both horizontally and vertically spaced from the pivot between the pivot lever 10 and the lever 11. The directional information vertically and horizontally understood for parked on a flat horizontal surface seating 1. The point of attack of the lever connection 14 on the pivot lever 10 is So compared to the pivot of the pivot lever 10 with the lever 11 on the one hand down and on the other hand to the free end of the pivot lever 10 and the functional part 3 is offset to the rear.

The lever connection 14 between the pivot lever 10 and the main body 2 comprises the handlebar lever 8, a control lever 15 and a balance lever 16. Other levers or the like would be conceivable, but rather to avoid from a constructive point of view. In the illustrated and insofar preferred seating 1 is the Handlebar 8 each connected via a pivotal connection 17 in the form of a rotary joint with the pivot lever 10 and the control lever 15.

The handlebar lever 8 extends substantially on the back of the control lever 11. In addition, the handlebar lever 8 is pivotally connected to the control lever 15 via a connection 17 in the form of a rotary joint. The same connection 18 is provided at the other end of the control lever 15 for connecting the control lever 15 to a compensating lever 16, which in turn is pivotally fixed to the holder 13 of the actuating lever 11. On the balance lever 16 could basically be omitted. However, in the present case, the compensating lever 16 makes possible a more comfortable adjustment path of the functional part 3 and is fixed on the holder 13 via the pivot connection 19.

The control lever 15 is connected between its compounds 17,18 with the balance lever 16 on the one hand and the handlebar lever 8 on the other hand with the lever 11. In the illustrated preferred seating 1, the control lever 15 is connected via a pivot connection 20 in the form of a rotary joint with the adjusting lever 11. Therefore, the control lever 15 is pivoted upon adjustment of the actuating lever 11 and thus moves the handlebar lever 8 depending on the adjustment of the actuating lever 11 upwards or downwards. As a result, the handlebar lever 8 pivots the pivoting lever 10 together with the functional part 3 back and forth about the pivotal connection 12 of the pivoting lever 10 with the adjusting lever 11.

• Als Ausgangszustand kann die zurückverschwenkte Stellung des Funktionsteils 3 gemäß Fig. 1 und 3 angesehen werden. Aus dieser Stellung kann das Funktionsteil 3 aufgeschwenkt werden, wobei dies zu einem Ausschieben der Lasche 6 des Hubstellers 5 aus der Führung 7 des Hubstellers 5 führt, die beim dargestellten und insoweit bevorzugten Sitzmöbel 1 in Form eines Gehäuses, zum Schutz vor Verschmutzung insbesondere in Form eines geschlossenen Gehäuses ausgebildet ist.

The operation of the seat 1 shown in the drawing is thus as follows:

• As an initial state, the pivoted-back position of the functional part 3 according to Fig. 1 and 3 be considered. From this position, the functional part 3 can be swung open, and this leads to a pushing out of the flap 6 of the lifting plate 5 from the guide 7 of the lifting plate 5, which in the illustrated and In that regard, preferred seating 1 in the form of a housing, designed to protect against contamination, in particular in the form of a closed housing.

The handlebar lever 8 is thereby displaced upward, wherein the handlebar lever 8 pivots the pivot lever 10 relative to the adjusting lever 11 about the common pivot axis between pivot lever 10 and lever 11 in a more upright position. In addition, the handlebar lever 8 pulls the connected to the handlebar lever 8 end of the control lever 15 with upward. Via the connection 20 between the control lever 15 and the adjusting lever 11, this leads to a lifting of the adjusting lever 11. The adjusting lever 11 is moved upwards by the adjusting lever 11 is partially pulled out of the holder 13 due to the rail system formed with the holder 13 upwards , The displacement of the actuating lever 11 upwards leads to a corresponding adjustment of the thereby pivoting functional part 3 upwards.

From this upper end position of the swivel fitting 4, in the Fig. 2 and 4 is shown, the swivel fitting 4 can be brought back into the lower end position in the Fig. 1 and 3 is shown. For this purpose, the handlebar lever 8 is moved down. This ensures via the coupling with the pivot lever 10 for pivoting the functional part 3 in the rear position. In addition, the handlebar lever 8 pivots the control lever 15 down, thereby shifting the lever 11 down. The lower portion of the control lever 11 is increasingly received in the holder 13 on the base body 2. The control lever 15 therefore moves the functional part 3 down.

The functional part 3 can only from the in the Fig. 2 and 4 shown end position back to the other end position or starting position according to Fig. 1 and 3 be adjusted. From an intermediate position, however, the functional part 3 can not be swung back in the appropriate direction or at most slightly, since this movement is then blocked by the Hubsteller 5. It is in this case, a clamping between the tab 6 and the guide 7 of the Hubstellers 5 generated. The corresponding clamping forces ensure that the tab 6 can not be pushed further into the guide 7. As a result, the pivot fitting 4 not further in the starting position according to Fig. 1 and 3 be pivoted. Thus, the functional part 3 is locked in the appropriate position, even if the user charged this. An accidental pivoting back of the functional part 3 is thus prevented. The situation is different only when the functional part 3 is initially adjusted into the pivoted-up end position and, consequently, the tab 6 of the lifting plate 5 is pulled out substantially opposite the guide 7.

If the functional part 3 is formed differently than the seat 1 shown as a footboard or armrest, preferably results in an analogous design of swivel fitting 4 and Hubsteller 5 with respect to the functional part 3 and the base body 2, which then by a seat, a frame or a Frame part, as a side part can be given. The arrangement and orientation of swivel fitting 4 and 5 Hubsteller in seating 1 but may then differ and be adapted to the connection of the functional part 3 with the base body 2 and to the function and desired adjustment of the functional part 3.

The operation of the Hubstellers 5 and thus its effect in relation to the pivoting of the swivel fitting 4 of the illustrated and so far preferred seating 1 is based on Fig. 5 to 12 explained in more detail.

In the Fig. 5 the Hubsteller 5 is shown in a perspective view. The Hubsteller 5 comprises at the rear end of the guide 7, which is in the form of a housing, and at the front end of the tab 6 each have a through opening 20. With the openings 20 of the Hubsteller 5 is pivotally mounted on the pivot fitting 4. The tab 6 is formed in the illustrated and insofar preferred seating 1 substantially strip-shaped, but could also be formed, for example, rod-shaped. In addition, the guide 7 of the Hubstellers 5 preferably has a corresponding, rectangular cross-section. In addition, the guide 7 is designed to protect against contamination in the form of a substantially closed housing.

In the FIGS. 6A and 6B the lift 5 is shown in a partially extended position in two sectional views perpendicular to each other. The tab 6 has a tapered inner end 21. This end 21 forms correspondingly on the two narrow sides of the tab 6, two outer surfaces 22 which extend obliquely to the opposite inner sides 23 of the guide 7, which are aligned parallel to each other and parallel to the extension direction of the tab 6 in the illustrated and so far preferred Hubsteller. Between the inclined surfaces 22 of the tab 6 and the opposite inner sides 23 of the guide 7 are formed according to clamping gaps 24, in which clamping elements 25 are added. When illustrated and so far preferred lifting plate 5, the clamping gaps 24 forming surfaces 22 are made flat and the clamping elements 25 have a cylindrical shape.

If the tab 6 from the in Fig. 6A shown position pressed into the guide 7, there is a blockage of the Hubstellers 5, since the clamping elements 25 wedged on both sides of the tab 6 in the clamping gaps 24 provided there. The clamping elements 25 can absorb such high clamping forces that the tab 6 is securely fixed relative to the guide 7.

The clamping elements 25 are held in the illustrated and insofar preferred lifting plate 5 in a clamping slide 26, which in turn is held on the tab 6. The clamping carriage 26 is formed in two parts and engages around the lower end of the tab 6. In this case, fingers 27 of the clamping carriage engage in a slot 28 of the tab 6 to slidably mount the clamping carriage 26 against the tab 6 to a small extent. The clamping carriage 26 also has on two opposite sides of friction tabs 29 which abut the cooperating with the clamping elements 25 inner sides 23 of the guide 7. The result caused stiction ensures that the clamping carriage 26 tends to maintain its position, as far as the clamping carriage 26 is freely displaceable relative to the flap 6.

In the extension direction form lateral lugs 30 of the tab 6 and the guide 7 corresponding stop surfaces, which together form an end stop 31 for the tab 6 and prevent further extension of the tab 6 from the guide 7. This is also a further adjustment of the connected with the Hubsteller 5 swivel fitting 4 is prevented.

If the tab 6 from in the Fig. 6A shown position further pulled out of the guide 7, the Hubsteller 5 enters the in the Fig. 7 shown position in which the tab 6 is pulled out almost to an end position of the guide 7. The clamping carriage 26, which bears against the pin 32 of the tab 6, has been moved as a result up to an end stop 33 for the clamping carriage 26. This end stop 33 limits the further displacement of the clamping carriage 26 in the extension direction of the tab. 6

If the tab 6 then continues in the in the Fig. 8 drawn position shown removed from the guide 7, slide the pin 32 of the tab 6 past the tab-shaped connecting elements 34 of the clamping carriage 26, after which the connecting elements 34 engage behind the pin 32 and thus form a separate connection between the tab 6 and the clamping carriage 26. The pins 32 are received in corresponding receptacles 35 of the terminal carriage 26. This is especially true in the Fig. 4 shown. The clamping carriage 26 is now connected in a position with the tab 6, in which the clamping elements 25 can not get into the clamping gaps 24 by clamping. Therefore, the tab 6 can be inserted without much effort in the guide 7.

In order to solve the separate connection between the clamping carriage 26 and the tab 6 again, the tab 6 must be in an initial position relative to the Guide 7 are inserted. Then, the pins 32 of the tab 6 engage in a free space 36 in the bottom 37 of the guide 7. Before the tab 7 reaches this starting position, the clamping carriage 26 comes into contact with the bottom 37 of the guide 7. The bottom 37 forms in this way an output stop 38 for the clamping carriage 26. The clamping carriage 26 is held in this position, while the tab 6 can be further inserted into the guide 7. In this case, the pin 32 of the tab 6 press on the connecting elements 34 of the clamping carriage 26 over and the positive locking connection between the tab 6 and the clamping carriage 26 dissolves. The pins 34 of the tab are then no longer included in the corresponding receptacles 35 of the clamping carriage 26. The tab 6 can thus be partially pulled out again while carrying the clamping carriage 26 to counteract in the corresponding position again a renewed insertion of the tab 6. In order to push the tab 6 back to the starting position in the guide 7, the tab 6 must first be pulled out again as described to the end position to set in this way the clamping carriage 26 via the separate locking connection to the tab 6.

In the Fig. 9 and 10 an alternative Hubsteller 5 'is shown. This differs from the Hubsteller 5 of Fig. 5 to 8 only by the design of the bottom 37 'and is also shown in a longitudinal section.

The bottom 37 'of the lifting plate 5' has two edge elements 38 'of the guide 7' which are pressed inwards and which provide the extension surfaces 39 'in the direction of extension. The stop surfaces 39 'form an output stop 40' for the clamping carriage 26. Instead of depressed inwardly edge elements 38 'of the guide 7', the stop surfaces 39 'could also be provided by another stop element.

If the connected via the already described separate connection with the clamping carriage 26 tab 6 in the direction of its initial position relative to the guide 7 'is inserted, first of the clamping carriage 26 reaches a fixed by the abutment surfaces 39' output stop 40 '. The clamping carriage 26 is held in this position, while the tab 6 can be further inserted against the guide 7 '. By the corresponding relative movement between the tab 6 and the clamping carriage 26, the pins 32 of the tab 6 are pushed past the connecting elements 34 of the clamping carriage 26 of the receptacle 35 thereof while the separate connection between the clamping carriage 26 and the tab 6 is released. The clamping carriage 26 remains nevertheless slidably held against the tab 6 on the tab 6, so that on the one hand the tab 6 can be pulled out again and on the other hand, the clamping elements 25 always prevent accidental pushing back of the tab 6 relative to the guide 7 ', as this basically has already been described. The connection of the detachable connection between the tab 6 and the clamping carriage 26 when pulling the tab 6 relative to the guide 7 'also takes place as previously described.

The illustrated and insofar preferred seating 1, in which the functional part 3 is designed as a headboard and the base body 2 as a backrest, both the pivot fitting 4 and the lifting plate 5 is aligned substantially vertically. However, it is also a horizontal orientation of swivel fitting and Hubsteller in question, especially in a functional part in the form of a foot and a base body in the form of a seat. Then, for example, the functional part can be pivoted from a lower rather vertical position to an upper, more horizontal position and back.

In the Fig. 11 and 12 a swivel fitting 50 is shown without seating. The pivot fitting 50 has instead of a Hubstellers a locking joint 51, via which the pivot lever 10 and the lever 11 are interconnected. The same components carry the same reference numerals. The locking joint 51 has a sprocket 52 which is rotatably connected to the pivot lever 10. On the lever 11, a locking mechanism 53 is set, the one with the sprocket 52nd corresponding toothing 54 has. The ratchet 53 is biased by a spring and therefore engages with its teeth 54 in the teeth 55 of the ring gear 52 a. The flanks of the teeth of the teeth 54,55 are formed so that the ring gear 52 can slide on the ratchet 53 when the pivot lever 10 is pivoted in the swung-open position. Then, the teeth 55 of the ring gear 52 pushes the ratchet 53 outward, so that the ring gear 52 is rotated tooth by tooth against the ratchet 53 and the ratchet 53 repeatedly engages in the ring gear 52. The mutually sliding flanks are inclined in the direction of the circumference of the ring gear 52. If the pivot lever 10 is pressed in the opposite direction, flanks of the corresponding toothings 54, 55 come into abutment against each other, which are aligned steeper with respect to the circumference of the toothed rim 52. Therefore, the ratchet 53 locks the ring gear 52 so that it can not rotate in the appropriate direction. Thus, the pivot lever 52 and connected to the pivot lever 10 functional part are set. The user of the chair can thus lean with parts of his body against the functional part, without the functional part yields and pivots back.

In order for the pivoting lever 10 can nevertheless be zurückverstellt again, the illustrated and so far preferred pivot fitting 50 must be pivoted into an end position and indeed in the fully pivoted position of the functional part. By means not shown, the ratchet 53 is then forcibly separated from the ring gear 52, so that the ring gear 52 can be rotated freely relative to the ratchet 53, to the other end position or the starting position. There, the separation of ratchet 53 and sprocket 52 is repealed and the pivot lever 10 can again pivot gradually in the pivoted position. The separation of ratchet 53 and sprocket 52 can be done by the ratchet 53 is pushed against the spring force to the outside and held there. This fixation is then forcibly lifted, for example by a stop, when the starting position is reached.

The pivot fitting 50 according to Fig. 11 and 12 otherwise works, so except the lock or determination of the pivot lever 10 in different positions as well as this in connection with Fig. 1 to 4 has been described. It is also noted that a locking / clamping joint could also be provided. In such a joint, the ratchet and the ring gear need not be separated from each other to return the pivot lever in the starting position. It only needs to be overcome a clamping between the pivot lever and the lever, so that the joint allows rotation in the direction of the starting position. Although it may still be provided means to effect a forced separation of ratchet and ring gear and cancel this separation again when the corresponding end positions of the pivot lever can be achieved. This is not necessary because of the clamping. It is particularly effective if at least one friction disc is clamped between the pivot lever and the adjusting lever, which has at least one friction surface on which an adjacent component slides, while the pivot lever is pivoted in the direction of the starting position.
