  • a generic piece of furniture is for example from the DE 20104534 U1 known.
  • This piece of furniture has a plate-like trained support segment for the legs of a user, which can be swung out of its unused starting position below a seat by means of a so-called scissors mechanism and in the swung-out state is then arranged approximately at the height of the seat.
  • This support segment is tilted by about 90 ° from the vertical to the horizontal.
  • a disadvantage of this configuration is that the scissors mechanism used is complicated and prone and beyond interfering in the extended state of the support segment to a considerable extent the aesthetic impression of the piece of furniture.
  • a seat is known in which a seat facing the first support portion is pivotable about a common pivot axis relative to the seat surface.
  • a second support region remote from the seat surface adjoins the first support region, which is closer to the seat surface, and which is pivotable relative to the first support section about a further pivot axis.
  • the first support section is approximately vertical in the unused state and approximately horizontally aligned in the used state.
  • a disadvantage of this embodiment is that the realization with an immediate pivoting of the support portion relative to the seat only with relatively thin support sections with only low padding thickness can be realized because the first support section is unused or not very limited under the seat displaced in the unused state.
  • Seating furniture is also known from the prior art, which have a fold-out support surface for the legs of the seated person, wherein this support surface is realized via a parallelogram mechanism.
  • the support surfaces are therefore aligned approximately horizontally both in the congested state and in the functional state.
  • the disadvantage of this is that also here the padding thickness limits the support sections is and that the corresponding connecting lever, which connect the seat with the extendable support portion, are necessarily provided laterally adjacent to the support surface or break through the support surface of the support portion. Both are considered aesthetically disadvantageous.

  • a particularly advantageous embodiment of this basic idea provides that in this case the path of movement of the pivot axis fixedly provided on the leg segment passes through an intermediate lowering in an intermediate position before reaching the functional position.
  • the movement path preferably corresponds to a circular path segment.
  • connecting member is movable with respect to a rotational degree of freedom relative to the main segment or a base frame on which the main segment rests.

It is considered particularly advantageous if in the stowed position, in contrast, the second pivot axis is arranged with respect to a horizontal behind the first pivot axis. The result of this is that during the transition from the stowed position into the functional position in the vertical, an intermediate lowering of the second pivot axis is achieved if, when pivoting about the first pivot axis, it is arranged directly below the first pivot axis. This lowering is advantageous because it allows particularly easy to ensure collision freedom of the leg segment and the main segment in the transfer of the leg segment in the functional position.

  • the pivot point 472 is controlled by this control member 492 in the direction of in the FIG. 5a shown arrow 474 force. This is done via the in Fig. 5 shown linear actuator 412.
  • This Kraftbeetzung leads starting from the state of Fig. 5a, 5b in that the leg segment 440 and the end segment 460 are transferred from their respective stowed state to their respective functional state, which in the Figures 5g and 5h is shown.
  • the leg segment 440 is pivoted downwards by about 90 ° relative to the functional state.
  • the end segment 460 is also pivoted about the leg segment 440 by about 90 ° and thus pivoted about 180 ° relative to its functional position.
  • the reel unit 476 is arranged in this initial state at the end pointing to the third pivot axis 403 of the guide track portion 483a of the first guide track 483 and is supported on this guide track 483, so that the end segment 460 can not fall further.
  • the roller unit 476 is in the initial state of FIGS. 5a and 5b arranged in an end region facing away from the second pivot axis 402, but not yet at the end stop of the guide tracks 480b. In this initial state, the entire system is completely determined by the fixed control member 492 and immovable in itself.
  • the shape of the first guide track portion 483a of the guide track 483 ensures that the roller unit 476 until reaching the intermediate state of the FIGS. 5e and 5f remains in said end portion of the second guide tracks 480b. Since the position of the roller unit 476 in the second guide track 480b simultaneously determines the relative position of the end segment 460 to the leg segment 440, this relative position likewise remains largely unchanged. This allows the transition from the starting position of the FIGS. 5a and 5b to the intermediate position of FIGS. 5e and 5f to avoid a collision between the end segment 460 and the floor not shown in the figures. This is further supported by the fact that the leg segment 440 in the transition to its functional position in the meantime at the state of FIGS. 5f . 5g is raised beyond its end position.
  • the roller 476a on the first guide track 483 has the boundary between the first guide track portion 483a and the second guide track portion 483b and thus completed a first movement phase, dominated in the relative movement between the main segment 420 and leg segment 440.
  • the second movement phase of movement of the end segment 460 begins. Since the movement limiting effect of the first guide track portion 483a with respect to the relative position of the end segment 460 to the leg segment 440 is no longer present in this second phase, the reel unit 476 may terminate the end portion of the second guide track 480b leave and be moved towards the opposite end.
  • seat piece of furniture allows it by the construction of its mechanics, with only a control member 492 to perform the complete sequence of movement of the stowed position of the leg segment 440 and the end segment 460 up to their functional position.
  • Acting as a slider roller unit 476 is used in conjunction with the first function track 483 to move in the first movement phase, the leg segment 440, while a relative movement of the end segment 460 to the leg segment 440 is largely blocked. The end of this blocking is achieved when the reel unit 476 reaches the boundary between the guide track sections 483a and 483b, since from this point on a movement of the roller unit 476 in the second guide tracks 480b is no longer limited by the first guide track 483.
