Definitions

  • the invention relates to a back-support arrangement for being placed on a sitting or lying surface of a piece of furniture, as stated in the preamble of claim 1.
  • the object of the invention is to present a new type of back-support which is constituted in such a manner that it can be placed anywhere on a sitting or lying surface of a piece of furniture, and which remains where it is placed completely without the use of further bracing means, securing means or the like.
  • the back-support arrangement is disposed on the surface, it remains here, even though one or more persons use it as a backrest with the full weight of the upper body, the reason being that special shape of the back-support, including the backward slope of the forward-facing surface and the specially-shaped underside, which must be substantially plane so as to achieve the greatest possible contact with the sitting or lying surface, makes it "cling" to the under surface so that it does not slide.
  • the pressure applied by a person (or several persons) leaning up against it will be transferred downwards against the support surface, thus contributing towards an increase in the friction so that the back-support arrangement cannot slide on the sitting or lying surface, but stands solidly on the surface and, in fact, more firmly the heavier it is leaned against.
  • the freely movable backsupport arrangements can be removed from the sitting or lying surface without any form whatsoever of mechanical separation or the like of the parts, so that the furniture can be instantly changed from a sofa or the like for sitting on to a piece of furniture for lying on, e.g. a bed.
  • a piece of furniture 1 for lying or sitting on consisting of a plane upper part 2 and an under part 3 which, for example as shown, can constitute a piece of furniture on four legs.
  • a substantially plane upper surface 4 of the furniture there are placed two back-support arrangements 5, each with a cushion 8 disposed in front of it, and thus the back-support arrangement 5 together with the cushion constitute a backrest 14 which is shown in more detail in figs. 2 and 4 of the drawing.
  • Each back-support arrangement 5 comprises an upholstered wedge 7, for example with triangular cross-sectional profile, and which can be produced or upholstered with any kind of material whatsoever.
  • the material used is polyurethane foam rubber, so-called hard cold-foam.
  • the foam rubber wedges 7 have a substantially plane support surface 6, arranged to rest on the surface 4, and two upwardly-extending side surfaces 12 and 13, in that the surface 12 inclines rearwards to such a degree that the load from a sitting person results in a substantially downwardly-directed load, so that the friction between the support surface 6 of the back-support arrangement 5 and the surface 4 is increased. It is important that the surfaces 4 and 6 are in close contact with each other, i.e. that the surface 6 is relatively plane.
  • the back-support arrangements 5 can be composed of two wedges as shown in fig. 3, joined along the breakline 9 so that the backrest acquires the shown angle characteristic which both increases the sitting comfort and the friction against the surface 4, but can also be configured in a completely rectilinear manner as shown in fig. 2.
  • Each foam wedge includes a support surface 6 arranged to rest on the surface 4, and two upwardly-extending, inwardly-sloping side surfaces 12 and 13.
  • the shape that the rear side shall have, i.e. the surface 13, is independent of the construction of the slope of the forwardly-facing side 12 and the under side 6. In this regard, one is thus freely disposed, which provides the possibility of different detail configurations, e.g. a straight, vertical back.
  • the shape shown with triangular cross-sectional profile is material saving.
  • the back-support arrangement 5 is upholstered with a suitable material, which can include fabric, leather or synthetic materials.
  • the support surface 6 must always be upholstered with a material which provides great friction against the surface 4.
  • a material can be leather, artificial leather, fabric, i.e. in many cases that material with which the side surfaces 12 and 13 are covered.
  • the support surface 6 can also be upholstered or covered with special friction-providing kinds of plastic or rubber, all depending on the material with which the surface 4 has been made or upholstered.
  • a cushion 8 is placed in front of the back-support arrangement (see fig. 1).
  • This can be, for example, an ordinary back-cushion stuffed with feathers or any kind of foam filling.
  • the cushion comprises that part of the backrest 14 which a person will normally lean against.
  • the back of the cushion 8 is preferably secured to the back-support element 5, see especially fig. 4, in such a manner that the cushion always stands up against the back-support arrangement and cannot slide on same.
  • the connection can be established by means of a lengthwise zip fastener, snap fastener, Velcro locks, or the like, or can be of a permanent execution by the sewing together of material or leather upholstery.
  • the joining together is shown executed along the lowermost edge of the back-support arrangement 5 and along the whole length of the back of the cushion, but naturally there is nothing to prevent the assembly being executed at other places in the surface where the cushion 8 touches the side surface 12.
  • the under side 10 of the cushion 8 can be provided with a friction-providing layer or materials such as described above with regard to the support surface 6, if the cushion upholstery in itself does not extend sufficient friction.
  • the height h of the back-support arrangement should be less than the sum of the depths p + b for the cushion 8 and the bottom surfaces of the back-support arrangement 5. It is thus ensured that sufficient friction is always achieved, and it is avoided that the backrest can tip backwards.
  • the surface 4 is of a relatively smooth leather, and if the support surface 6 is covered with a non-skid layer of friction-providing material, e.g. polyurethane or rubber-covered material, and if the cushion 8 is upholstered with relatively smooth leather, e.g. the same leather as that with which the surface 4 is covered, then the backrest 14, i.e. the back-support arrangement 5 with cushion 8, will remain standing firmly on the surface.
  • a non-skid layer of friction-providing material e.g. polyurethane or rubber-covered material
