Definitions

  • the invention relates to a piece of seating furniture, comprising a seat assembly with a seat surface section and a backrest section formed in one piece with the seat section, and a foot assembly that supports the seat assembly.
  • Seating furniture in which the seat and backrest are formed in one piece with one another are known from the prior art. They are used, for example, in the garden or in lounges.
  • the leg assembly of these chairs usually consists of a metal frame that is bolted to the seat assembly. If one sits on such a piece of seating furniture and leans backwards, the connection between the seat surface and backrest sections forming an L-shape is stressed. Frequent deformation leads to the formation of microcracks, which in extreme cases can lead to the backrest section tearing or even breaking off.
  • a piece of seating furniture of the type mentioned at the outset which further comprises a compressible assembly which is arranged between the seat assembly and the foot assembly. If a person has sat down on the chair and leans backwards, the compressible assembly is compressed more in a partial area adjacent to the backrest section than in one of them Backrest section removed portion. As a result, the compressible assembly can absorb part of the movement of the backrest section caused by the reclining, so that the connection between the seat surface section and the backrest section is deformed less and is therefore less heavily loaded.
  • the property "compressible" in connection with the present invention is considered to be given if the thickness of the compressible assembly measured from the seat surface section to the support section changes under the weight of a person weighing 80 kg who is on the Seating has been reduced by more than 1%.
  • the compressible assembly can comprise a foam body, preferably a foam body formed from memory foam.
  • a foam body preferably a foam body formed from memory foam.
  • An open-pored polyurethane foam, for example, can be used as the memory foam.
  • the compressible assembly for example the foam body
  • the compressible assembly in a wedge shape, i.e. as an assembly whose thickness is greater in a partial area adjacent to the backrest section than in a partial area remote from the backrest section
  • the upper side of the compressible assembly facing the seat surface portion and the underside of the compressible assembly facing the support portion run essentially parallel to one another.
  • the thickness of the compressible assembly, for example the foam body can be between approximately 40 mm and approximately 60 mm, preferably approximately 50 mm.
  • the adjacent in the direction of the backrest section The length measured in the partial area to the partial area removed from the backrest section and the width of the compressible assembly measured orthogonally thereto must be dimensioned in such a way and/or the compressible assembly can be arranged in such a way that the front edge of the compressible assembly is set back by no more than 10 cm compared to the front edge of the seat surface section, while the lateral edges of the compressible assembly are substantially flush with the lateral edges of the seat portion.
  • the shape of the compressible assembly for example the foam body, to be freely selectable in the length and/or width direction. This is particularly advantageous when the seat section is made of a transparent material, since the compressible assembly can then be used in a variety of ways for design purposes, as long as their actual function is not impaired.
  • the shape of the compressible assembly in particular its outer contour, can be designed in the form of a logo and/or a logo can be milled into its surface facing the seating area section. Furthermore, it can be single-colored or multi-colored. Finally, it is also possible to encase the compressible assembly in a covering, whereby the covering can be made of textile, leather or the like, for example to match the surfaces of other furniture, walls or the like.
  • At least one spring unit be provided, one end of which can be positively connected to the seat surface section of the seat assembly and the other end of which can be positively connected to the support section of the foot assembly.
  • a screw such as a Countersunk screw can be arranged, which can be screwed with an external thread into a complementary thread of the seat surface section or of the support section, wherein a spring of the spring unit can be positively connected to the screw.
  • At least one spring unit is advantageously arranged in at least each of the four corner areas of the seat surface section.
  • At least one of the spring units passes through a through hole provided in the compressible assembly.
  • the spring units hold the compressible assembly in place and allow for its replacement if necessary.
  • the seat surface section and/or the backrest section are essentially flat.
  • the seat surface section and/or the backrest section it is also conceivable for the seat surface section and/or the backrest section to be arched, with the arching towards the inside of the L-shape formed by the two sections preferably being concave. Due to the curvature, at least one of the two sections can have the shape of a shell, ie a seat shell or a back shell.
  • the seat assembly can be made of a material that has a lower compressibility than the material of the compressible assembly, preferably is substantially incompressible compared thereto.
  • the seat assembly can be made of plastic, for example PMMA (polymethyl methacrylate) or PC (polycarbonate) or PP (polypropylene) or CFRP (carbon fiber reinforced plastic) or GRP (glass fiber reinforced plastic), in particular transparent plastic.
  • the seat assembly can be bent, starting from a plate-shaped element, into the L-shape having the seat surface section and the backrest section.
  • the thickness of the plate-shaped element can advantageously be between about 8mm and about 15mm, preferably about 12mm.
  • the leg assembly has, in addition to the support section, a substantially horizontally running base section and a connecting section, which connects the base section and the support section and essentially forms a C-shape with them. Due to its essentially C-shaped design, the foot assembly is also able to absorb at least part of the tilting angle of the backrest section caused by leaning back.
  • the connecting section is arranged on the back of the chair, ie on that side of the chair where the seat assembly has the backrest section.
  • the supporting section, the connecting section and the bottom section of the foot assembly are also formed in one piece with one another, and/or the foot assembly is made of plastic, for example PMMA (polymethyl methacrylate) or PC (polycarbonate) or PP (polypropylene) or CFRP (carbon fiber reinforced plastic).
  • plastic for example PMMA (polymethyl methacrylate) or PC (polycarbonate) or PP (polypropylene) or CFRP (carbon fiber reinforced plastic).
  • plastic or GRP (glass fiber reinforced plastic), in particular made of transparent plastic, and/or that the foot assembly, starting from a plate-shaped element, is inserted into the support section, the connecting portion and the bottom portion is bent C-shape.
  • the thickness of the plate-shaped element can be between about 10mm and about 25mm, preferably about 20mm.
  • connection section and the support section can enclose an angle of more than 90° between them, preferably an angle of between approximately 95° and approximately 105°, even more preferably an angle of approximately 100°.
  • connecting section and the base section can enclose an angle between them of between approximately 90° and approximately 80°, preferably an angle of approximately 85°.
  • the seat assembly and the foot assembly can be made of the same material, in particular the same plastic.
  • that from which the seat assembly is made can have a smaller thickness than that from which the foot assembly is made.
  • the seat assembly and/or the foot assembly can also be made of metal, for example steel or aluminum, or of wood, for example laminated wood, as an alternative to being made of plastic.
  • metal for example steel or aluminum
  • wood for example laminated wood
  • the person skilled in the art is also familiar with corresponding deformation processes for these materials in order to enable production from a plate-shaped element.
