Description

The invention relates to a seat / reclining furniture, in particular armchair or chair, with a back part, a seat part and an adjustable footrest assembly, which is pivotable relative to the seat part between a folded basic position below a seat surface of the seat part and a deployed use position, wherein the footrest assembly comprises a frame , Which is attached to the part of the seat part or the seat part, and comprises a relative to the frame pivotable footrest.

Such furniture is basically known. For example, go out DE 10 2005 001 875 A1 a seat / reclining furniture according to the preamble of claim 1.

The pivotable footrest should in the unfolded use position as large as possible, i. Provide long contact surface, so that even a relatively large person a full foot rest is available. At the same time, the footrest should be as compact as possible and well stowed under the seat part in the retracted basic position.

The problem here is in particular the relatively low ground clearance, ie the clear height between the floor on which the furniture stands, and the underside of the seat part in the region of the front edge of the seat part. The desired useful length of the footrest in the unfolded use position is practically always greater than this clear height. There are therefore already multi-part footrests are known, which in a basic position corresponding state in which the parts of the footrest pushed together, folded, retracted or folded, are pivoted out of the basic position, wherein after reaching the unfolded use position the footrest forming parts are moved apart again. This can for example be done directly manually or indirectly via a fitting, which in turn is either manually or manually operated.

This adjustment of the footrest can be accompanied by an adjustment of the seat part and in particular the back part. It is in fact desirable in practice that the footrest is folded out in a so-called relax or rest position of the furniture, in which the seat part is lowered in the rear area and thus provides a more inclined seat surface, wherein also in this relaxation or Rest position the backrest formed by the back part is also more inclined than in the basic position of the furniture.

So far, such footrests are provided with a separate cover or with a separate padding, which is not connected to the cover or the padding of the seat part. Also, the individual parts of multi-part footrests are covered or upholstered separately. In this way it is ensured that the cover or padding is not affected by the fact that the footrest is pivoted relative to the seat part and also in a multi-part footrest, the individual parts are moved relative to each other. In particular, it can not come in the folded-in basic position to a disturbing folds of the cover or the upholstery.

The object of the invention is to develop a sitting / reclining furniture of the type mentioned in that even with relatively low ground clearance a footrest is provided with the largest possible contact surface, in addition, there are no restrictions on the further equipment, especially in terms of cover or upholstery options.

The solution of this object is achieved by the features of independent claims 1 and 14.

The footrest according to the invention has in the retracted basic position a greater length than in the intermediate position. The invention is thus based on the recognition that in the retracted basic position, the length of the footrest does not necessarily have to be minimal. Rather, it was recognized that, so to speak, the "bottleneck" is that pivotal position of the footrest, in which the footrest is oriented at least substantially vertically, since in this position, the available on the respective furniture ground clearance or clear height comes into play.

The invention thus makes it possible to shorten or contract or retract the footrest during pivoting and pivoting so far that given by the ground clearance or the clear height "bottleneck" can be easily passed through. This in turn opens the possibility to provide the entire footrest, optionally including the seat part, with a common, continuous cover or with a common, continuous padding. A possibly resulting in contracted footrest drapery of the cover or upholstery is inventively unproblematic, since this effect occurs only temporarily during the swinging or pivoting. While in the unfolded use position this problem does not exist anyway, but can be ensured by the invention that even in the retracted basic position drapery or similar disturbing effects that may occur due to the required shortening of the footrest, are not a problem. According to the invention, a tightening or smoothing of the cover or upholstery is achieved by the greater length of the footrest in the basic position compared to the intermediate position.

The invention thus also allows for multi-part footrests with retractable and retractable extension a continuous cover or a continuous upholstery even if the footrest in the unfolded use position has a comparatively long effective length, as it increasingly from the customer is expected, and if the footrest due to a relatively low ground clearance or clear height must be comparatively shortened to be unfolded and folded.

In possible further developments, the footrest arrangement according to the invention can have one or more features of the footrest arrangement described above in connection with the seat / reclining furniture according to the invention.

The invention will now be described by way of example with reference to the drawings, which are incorporated in FIGS Fig. 1 to 6 shows different views of an embodiment of a sitting / lying furniture according to the invention.

While the Fig. 2 an overall view with the relevant individual components of the furniture according to the invention at the same time in the basic position I, an intermediate position II and the use position III shows, is first based on Fig. 1 The concept of the pivoting footrest will be explained.

Fig. 1 shows various views of a footrest assembly 15 including, inter alia, a frame 17 which forms part of the seat portion 13 (FIG. Fig. 2 ) or attached to the underside of the seat part 13. The frame 17 or a part of the frame serving as a base for movable components and the seat part 13 are not movable relative to one another in this exemplary embodiment, thus behaving kinematically like a unit.

In all representations of the Fig. 1 is the footrest assembly 15 shown with unfolded, located in the use position Fußstütze, wherein in the three right representations only a part of the relevant components is shown here.

The footrest comprises a base part 19 which is pivotable about an axis 25 relative to the frame 17. Relative to the base part 19, an extension 21 is slidably mounted. The extension 21 can retracted or retracted and extended or withdrawn. For the guide between base 19 and extension 21 a so-called full extension is provided.

As Fig. 2 shows, the seat part 13 together with footrest assembly 15 is supported on a pedestal 51 of the furniture via a support 29 having a in Fig. 1 not shown, and a head portion comprises, from which in Fig. 1 in the middle right representation of two support members 61, 63 and in the illustration above it further, not shown here components are shown.

An electric motor 27 is connected between the frame 17 and the carrier 29. By means of the motor 27, the frame 17 relative to the carrier 29 between the in Fig. 1 shown relaxation position, which corresponds to the unfolded use position of the footrest, and a basic position, not shown here are adjusted. For this purpose, the frame 17 with a front pivot lever assembly 31 and a rear pivot lever assembly 33 is coupled to the support member 61. The frame 17 is in the in Fig. 1 lowered relaxation position shown in the rear. This is also in Fig. 2 to recognize.

The adjustment of the frame 17 and thus the seat portion 13 causes the pivoting of the base portion 19 of the footrest, via a pivot mechanism 35. The hinged to the support member 61 rear pivot lever assembly 33 actuates a push rod assembly 53 which actuates a pivotally mounted, two-armed lever 55, the in turn actuates an angled pivot lever 56. The pivot lever 56 is pivotally connected to a further pivot lever 57, in an area between the articulation of this pivot lever 57 on the support member 63 on the one hand and an articulated connection of this pivot lever 57 with another pivot lever 59 on the other. The latter pivoting lever 59, in turn, is finally connected in an articulated manner to the base part 19. Instead of a single lever, a lever arrangement with two or more parallel individual levers can be provided in each case.

The adjustment of the frame 17 thus controls the pivotal movement of the base member 19 and thus the footrest as a whole. The extension and retraction of the extension 21, however, is derived from the pivotal movement of the base member 19. For this purpose, an actuating arrangement 37 is provided. In this regard, the illustrations in Fig. 6 directed.

The adjusting arrangement 37 comprises an elongated, provided in the form of a rod control member 35 which is articulated on the one hand on the frame 17 and on the other hand connected to a two-armed rotary lever 41 which is part of a Umsetzorgans 47.

The adjusting axis 39, about which the control rod 45 can pivot relative to the frame 17, is parallel to the pivot axis 25 of the base member 19, but at a distance from this pivot axis 25. The control axis 39 is disposed below the pivot axis 25, wherein the two axes 25th , 39 lie in a plane that is approximately vertical.

This configuration has the consequence that the effective length of the control rod 45 varies during the pivotal movement of the base member 19 between the retracted basic position I and the unfolded Nutzstellung III, ie, the junction between the control rod 45 and the two-armed rotary lever 41 is a function of the angular position of the Base part 19 more or less far away from the pivot axis 25 of the base part 19. Consequently, the position of the rotary lever 41 of the pivotal position of the base member 19 is dependent. The rotary lever 41 is rotatably mounted about an axis of rotation 43 on the base part 19, wherein the rotation axis 43 is perpendicular to the pivot axis 25 and perpendicular to the support member defined by the base 19.

Due to the relative arrangement of the pivot axis 25 and the adjusting axis 39, the effective length of the control rod 45 is maximum when the base part 19 is parallel to the plane defined by the two axes 25, 39. This is the case in the intermediate position II, when the ground clearance or the clear height between the bottom and front edge of the seat part 13 comes into play. In this intermediate position II is also due to the above-described adjustment of the seat part 13, ie the so-called seat lowering, whose front edge region relative to the basic position I raised ( Fig. 2 ). Since the pivot axis 25 of the base part 19 is located in the region of the front edge of the seat part 13, the ground clearance or the clear height is increased by the seat part adjustment and the seat lowering.

If the base member 19 is further folded against the explained intermediate position II or further expanded, respectively reduces the effective length of the control rod 45. This means that both in the retracted position I and in the unfolded Nutzstellung III of the rotary lever 41 by means of the control rod 45th is pivoted out of the extreme position II - in the upper illustration of the Fig. 6 counterclockwise. Since the rotary lever 41 is coupled via a further lever 49 with the retractable extension 21 of the footrest, this configuration has the consequence that outside the intermediate position II with a maximum retracted extension 21, this is more or less extended. In the utility position III, in which the footrest is fully unfolded, the extension 21 is in its furthest extended position. In the basic position II with a maximum wide folded footrest extension 21 is also extended, but to a lesser extent than in the unfolded position III. This is the top illustration in Fig. 6 , the overview representation of Fig. 2 and a comparison of the individual representations in the Fig. 3 . 4 and 5 refer to. For example, the extension 21 is extended in the basic position I with respect to the intermediate position II about 5 cm far. This is sufficient to disturbing folds of the cover or the padding 23rd when pivoting to the basic position I eliminate, as can be seen from a comparison of Fig. 4 and 5 evident. In Fig. 4 a drape of the cover or the padding 23 is indicated.

By means of the control member 45 and formed in the illustrated embodiment of the rotary lever 41 and the other lever 49 Umsetzorgans 47 Consequently, the pivotal movement of the base member 19 is implemented in the sliding movement of the extension 21 relative to the base member 19.

While in the illustrated embodiment, the adjustment of the seat part 13 by means of the motor 27, alternatively, a manual adjustability may be provided, for example via a mechanism which makes it possible to bring about alone by a shift in weight of a user sitting in the furniture, the explained seat lowering, which then turn automatically leads to swinging or unfolding of the footrest and consequently again automatically causes the extension of the extension 21 relative to the base part 19 of the footrest.
