Definitions

  • the invention relates to a piece of seating furniture according to the preamble of claim 1.
  • a relevant in the context of the invention piece of furniture is 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 scissor mechanism and is then arranged in the swung-out state 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 in this case the padding thickness is limited to the support sections and that the corresponding connection lever which connect the seat with the extendable support section, are necessarily provided laterally adjacent to the support surface or break the support surface of the support section. Both are considered aesthetically disadvantageous.
  • a support section which is aligned horizontally both in the congestion state and in the functional state, by appropriate design of the lever is directed to pivot by appropriate design of the lever in the transition from the congestion state to the functional state in an intermediate state about a horizontal pivot axis to ensure that the support section can be passed without collision on a main section with seat.

  • the legrest is movable relative to a seat surface, wherein a positive guidance is realized by a double lever design.
  • a chair which has a leg rest, which is arranged in a stowage position under a seat and opposite to this can be moved forward in a functional position.
  • the seat and the leg rest are hinged together via a coupling lever.
  • the object of the invention is to develop a generic piece of seating furniture to the effect that even heavily padded leg segments can be used and / or that the passage between congestion and functional state realizing mechanism is better hidden than in the known from the prior art seating furniture pieces.
  • This design according to the invention is based on the basic idea of the invention that the leg segment is brought out of its stowage position under the main segment into its functional position in front of the leg segment with a superimposed movement.
  • 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.
  • the link provided in accordance with this invention is movable with respect to a rotational degree of freedom with respect to the main segment or a base frame on which the main segment rests.
  • the leg segment in turn is movable relative to the intermediate segment with respect to a further degree of rotational freedom.
  • these two degrees of freedom make it possible to design the transitional movement between the stowage position and the functional position of the leg segment in such a way that even with a comparatively thick embossment of the leg segment, this can be guided past the main segment without collision and can be arranged in its pivoted position in front of the main segment.
  • the two pivot axes which always remain at a constant distance from each other through the connecting member, are formed parallel to each other. It is also possible to use a plurality of connecting members whose first and second pivot axes coincide in each case.
  • the seating furniture has a preferably upholstered seating area, with the seat cushion or the seat cushion as the main segment in the Meaning of the invention is understood.
  • This main segment may be formed stationary, so that it is not movable to an external reference system, such as a floor on which the piece of furniture stands.
  • the main segment may also be movable relative to this reference frame and a base frame fixed in this reference frame, this flexibility preferably being limited to a slight pivoting, displacement or superimposed sliding and pivoting movement of the main segment relative to the base frame.

  • a leg segment is understood a part of the seating furniture piece according to the invention, which has at least one support surface and any kind of hinge means, which ensure the pivotability about the second pivot axis.
  • the substantially horizontal orientation of the support surface of the leg segment in the functional position is to be understood so that the support surface deviates on average by no more than 30 ° from a horizontal.
  • the support surface is tilted in the stowage position.
  • the tilt angle between stowed position and functional position is preferably between 70 ° and 180 °. It is particularly advantageous if the support surface is aligned substantially vertically in the congested state, this means that a resulting surface normal on the support surface by a maximum of 10 ° relative to the horizontal facing upwards or by a maximum of 30 ° relative to the horizontal downwards.
  • the connecting member is a rigid component, which is designed for pivotable articulation on the main segment or the base frame on the one hand and the leg segment on the other hand. As rigid while a component is considered, which ensures a constant distance between the first and second pivot axis.

Axles in the sense of this invention are understood to mean axes of rotation in a non-figurative sense. An axis therefore only describes the relative mobility about an imaginary stationary axis of rotation. All known from the prior art for this purpose, suitable machine elements such as bolts, axle sections, Welzlagerorganizen and the like are included.

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 angle between a vertical and the main extension direction of the connecting member is in the stowage position preferably between 0 and 30 °, wherein the main extension direction of the connecting member is understood to be a direction that runs along a connecting line of the first and second pivot axis.
