    Description

    [0039] The invention will be described in the following by way of example with reference to the drawing that shows different views of an embodiment of a piece of seating/reclining furniture in accordance with the invention in FIGS. 1 to 6.

    [0040] While FIG. 2 shows a total overview with the relevant individual components of the furniture in accordance with the invention simultaneously in the base position I, in an intermediate position II and in the position of use III, the concept of the pivotable footrest should first be explained with reference to FIG. 1.

    [0041] FIG. 1 shows different views of a footrest arrangement 15 that inter alia comprises a frame 17 that forms a part of the seat part 13 (FIG. 2) or is fastened to the lower side of the seat part 13. The frame 17 or a part of the frame serving as the base for movable components and the seat part 13 are not movable relative to one another in this embodiment and thus behave as a unit in a kinematic regard.

    [0042] In all the representations of FIG. 1, the footrest arrangement 15 is shown with an outwardly folded foot rest located in the position of use, wherein only some of the respective components relevant here are shown in the three right hand representations.

    [0043] The footrest comprises a base part 19 that is pivotable about an axis 25 relative to the frame 17. An extension is displaceably supported relative to the base part 19. The extension 21 can be retracted or pulled in and extended or pulled out. A so-called full extension is provided for the guide between the base part 19 and the extension 21.

    [0044] As FIG. 2 shows, the seat part 13 together with the footrest arrangement 15 is supported at a foot 51 of the piece of furniture via a carrier 29 that comprises a support column not shown in FIG. 1 as well as a head section of which two carrier parts 61, 63 are shown in the middle right hand representation in FIG. 1 and further components, not designated in more detail here, are shown in the representation thereabove.

    [0045] An electric motor 27 is connected between the frame 17 and the carrier 29. The frame 17 can be adjusted by means of the motor 27 relative to the carrier 29 between the position of relaxation shown in FIG. 1, that corresponds to the outwardly folded position of use of the footrest, and a base position not shown here. The frame 17 is coupled for this purpose to the carrier part 61 with a front pivot lever arrangement 31 and with a rear pivot lever arrangement 33. The frame 17 is shown lowered in the rear region in the position of relaxation shown in FIG. 1. This can also be recognized in FIG. 2.

    [0046] The adjustment of the frame 17 and thus of the seat part 13 effects the pivoting of the base part 19 of the footrest, and indeed via a pivot mechanism 35. The rear pivot lever arrangement 33 connected in an articulated manner to the carrier part 61 actuates a connecting rod arrangement 53 that actuates a pivotably supported two-armed deflection lever 55 that in turn actuates an angled pivot lever 56. The pivot lever 56 is connected in an articulated manner to a further pivot lever 57, and indeed in a region between the articulated connection of this pivot lever 57 to the carrier part 63, on the one hand, and an articulated connection of this pivot lever 57 to a further pivot lever 59, on the other hand. The last-named pivot lever 59 is in turn finally connected in an articulated manner to the base part 19. Instead of one single lever, a respective lever arrangement can be provided with two or more single levers active in parallel.

    [0047] The adjustment of the frame 17 thus controls the pivot movement of the base part 19 and thus of the footrest in its totality. The moving out and moving in of the extension 21, in contrast, is derived from the pivot movement of the base part 19. An adjustment arrangement 37 is provided for this purpose. Reference is also made to the representations in FIG. 6 in this respect.

    [0048] The adjustment arrangement 37 comprises an elongated control member 35 that is provided in the form of a bar and that is connected in an articulated manner to the frame 17, on the one hand, and is connected to a two-armed swivel lever 41, on the other hand, that is a component of a conversion member 47.

    [0049] The adjustment axis 39 about which the control bar 45 can pivot relative to the frame 17 extends in parallel with the pivot axis 25 of the base part 19, but at a spacing from this pivot axis 25 in so doing. The adjustment axis 39 is arranged beneath the pivot axis 25, with the two axes 25, 39 being disposed in a plane that extends approximately vertically.

    [0050] This embodiment has the consequence that the effective length of the control bar 45 during the pivot movement of the base part 19 varies between the inwardly folded base position I and the outwardly folded position of use III, i.e. the connection point between the control bar 45 and the two-armed swivel lever 41 is more or less remote from the pivot axis 25 of the base part 19 in dependence on the angular position of the base part 19. The position of the swivel lever 41 is consequently also dependent on the pivot position of the base part 19. The swivel lever 41 is supported at the base part 19 rotatable about an axis of rotation 43, with the axis of rotation 43 extending perpendicular to the pivot axis 25 and perpendicular to the support surface defined by the base part 19.

    [0051] Due to the relative arrangement of the pivot axis 25 and of the adjustment axis 39, the effective length of the control bar 45 is at a maximum when the base part 19 extends in parallel with the plane defined by the two axes 25, 39. This is the case in the intermediate position II when the clearance between the floor and the front edge of the seat part 13 comes into play. In this intermediate position II, due to the above-explained adjustment of the seat part 13, i.e. the so-called seat lowering, its front marginal region is additionally raised with respect to the base position I (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 clearance is increased by the seat part adjustment or the seat lowering.

    [0052] When the base part 19 is folded further inwardly or is folded further outwardly with respect to the explained intermediate position II, the effective length of the control bar 45 respectively decreases. This means that the swivel lever 41 is pivoted outwardly out of the extreme position II—counter-clockwise in the upper representation of FIG. 6—both in the inwardly folded base position I and in the outwardly folded position of use III. Since the swivel lever 41 is coupled to the inwardly and outwardly movable extension 21 of the footrest via a further lever 49, this embodiment has the consequence that said extension is moved out more or less outside the intermediate position II with a maximally inwardly moved extension 21. In the position of use III in which the footrest is completely outwardly folded, the extension 21 is located in its position outwardly moved out the furthest. In the base position II with a footrest folded inwardly by a maximum distance, the extension 21 is likewise moved out, but to a lesser degree than in the outwardly folded position of use III. This can be seen from the upper representation in FIG. 6, from the overview representation of FIG. 2 and from a comparison of the individual representations in FIGS. 3, 4, and 5. The extension 21 is, for example, moved out approximately 5 cm with respect to the intermediate position II in the base position I. This is sufficient to eliminate a disturbing fall of the folds of the cover or of the upholstery 23 on the pivoting into the base position I, as can be seen from a comparison of FIGS. 4 and 5. A fall of the folds of the cover or of the upholstery 23 is indicated in FIG. 4.

    [0053] The pivot movement of the base part 19 is consequently converted into the sliding movement of the extension 21 relative to the base part 19 by means of the control member 45 and the conversion member 47 formed in the embodiment shown by the swivel lever 41 and the further lever 49.

    [0054] While the adjustment of the seat part 13 takes place by means of the motor 27 in the explained embodiment, a manual adjustability can alternatively also be provided, for example via a mechanism that makes it possible to bring about the explained seat lowering solely by a weight transfer of a user sitting on the piece of furniture, which then in turn automatically results in the outward pivoting or in the outward folding of the footrest and consequently again automatically effects the moving out of the extension 21 relative to the base part 19 of the footrest.
