Definitions

  • the invention relates more particularly to furnishing articles of the convertible sofa bed type.
  • a sofa bed has a metal frame generally constituting a slatted base or the like.
  • This box spring receives a mattress in two articulated parts, one of which forms the seat while the other acts as a backrest.
  • the bed base is also produced in two articulated parts by means of an appropriate mechanism capable of ensuring the automatic transformation of the article, either into a bench or into a bed.
  • FIGS. 1 and 2 respectively show the bench seat in the bench position (figure 1) and in the bed position (figure 2).
  • the object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
  • the problem which the invention proposes to solve is, in the case of a bench seat equipped with a mattress in two articulated parts and of the same dimension, of automatically reducing the depth of the seat during the transformation into a bench.
  • a device which includes means capable of ensuring the articulated coupling of the two seat and back parts so that, in the bench seat position, the seat part is automatically partially maintained under the back part, to correspondingly reduce the depth of said seat part.
  • the depth of the seat which, according to the state of the art cited is about 60 cm, can be reduced, according to the device of the invention, to very substantially 50 cm in the bench position , which corresponds to the generally accepted dimension to obtain optimum comfort.
  • the articulation means consist of at least one deformable band fixed at the junction of the two parts and at least set back from the corresponding edge of the seat part.
  • the band or bands are fixed, on the one hand, at the edge of the backrest and, on the other hand, set back from the corresponding edge of the seat part.
  • the distance between the zone of attachment of the strip (s) to the seat part with respect to the edge is determined to correspond to the desired seat depth.
  • the strip or strips are made of a non-elastic textile material.
  • Another problem which the invention proposes to solve is to maintain the seat so that it comes under the back part, in the bench position, in order to avoid its sliding as and when the transformation into the bench position.
  • the seat part is equipped with connecting means able to cooperate with a corresponding part of a box spring frame constituting the framework of the bench seat.
  • the connecting means consist of strips of self-gripping ribbons enclosing the section of one of the uprights of the box spring frame.
  • the hook-and-loop tapes are fixed overhanging the underside of the seat part located at the junction with the back part.
  • Figure 1 is a side view in schematic section showing a bench seat according to the prior art, in the bench position.
  • Figure 2 is a view corresponding to Figure 1 in the bed position.
  • Figure 3 is a side view in schematic section showing a bed seat equipped with the device according to the invention, in the seat position.
  • Figure 4 is a view corresponding to Figure 3 in the bed position.
  • Figure 5 is a perspective view of the sofa bed equipped with the device, in the bed position.
  • Figure 6 is a partial perspective view showing the attachment of the seat part.
  • a sofa bed comprises in a perfectly known manner, a mattress in two identical parts (1) and (2). Each of these parts is mounted in combination with a frame serving as a bed base (3) also produced in two articulated parts (3a) and (3b). The articulation of the bed base is carried out by any system allowing to pass automatically from the bench position to the bed position.
  • the articulation system of the frame is not described in detail because, on the one hand, it can have different embodiments and, on the other hand, it is not part of the specific object of the invention.
  • the two parts (1) and (2) are generally arranged in a mattress cover.
  • the part (1) constitutes the seat, while the part (2) constitutes the backrest, in combination, one and the other, with the parts (3a) and (3b) of the box spring frame (3).
  • the two parts (1) and (2) are articulated by at least one deformable strip (4) fixed at the junction of the two parts (1) and (2) and at least set back from the corresponding edge (1a) of the seat part (1).
  • the function of this band is to ensure the articulation of the two parts of the mattress (1) and (2) and to allow the shortening in the bench position of the seat function, by keeping the part of the seat (1) under the folder part (2).
  • the strip (4) is fixed, on the one hand, at the edge (2a) of the backrest (2) and, on the other hand, set back from the corresponding edge (1a) of the seat (1) ( Figures 3 and 4).
  • the strip (4) is made of a non-elastic textile material. As shown in Figure 5, the strip (4) is fixed by sewing or otherwise, over almost the entire length of the parts (1) and (2). It is not excluded to produce the strip (4) in several elements.
  • the seat part (1) has connecting means (5) cooperating with a part of the bed base (3a), for example with one of the longitudinal edges (3a1).
  • These connecting means can be constituted by self-gripping ribbons such as those known under the brand VELCRO (FIG. 6). More particularly, the hook-and-loop tapes (5) are fixed overhanging the underside of the seat part located at the junction with the back part.
  • the device can be applied to any type of mattress fitted to any seat system convertible into a bed.
