Definitions

  • the present invention relates to seat elements comprising a flexible lining. It relates more particularly to the production of a seat element by fixing rigid or deformable elements fixed to the periphery of a lining able to resist laceration or similar acts of vandalism.
  • Phase (3) of this process turns out to be expensive to implement, because of the price of the molds to be used.
  • the present invention aims to remedy this drawback by proposing a seat element equipped with a flexible lining, in particular of the type mentioned above, which can be produced in a simple manner using means usual in the art.
  • the invention also aims to provide a flexible and elastically deformable seat element, which can adapt to the anatomy of the user and then resume its initial shape, while remaining perfectly integral with the frame of the seat.
  • the invention aims to propose a seat element which can be made integral with the frame of a seat by simple pinching between two elements of this frame which can themselves be assembled by snap-fastening.
  • the subject of the invention is a seat element equipped with a lining comprising a sheet of helical metal springs embedded at least partially in a layer of plastic material, said lining having at least two opposite edges, along substantially all of the length of each of the two said edges, a longitudinal element being held integral with the ply of springs and / or said layer of plastic material by a bead of plastic material, characterized in that the longitudinal elements are flexible or rigid, and in that that the flexible longitudinal elements comprise a metal or plastic strip, while the rigid longitudinal elements comprise a metal profile.
  • said longitudinal element flexible or rigid, will be applied to the periphery of the lining, along an edge thereof, directly against the part of the ply of spring emerging from the layer of plastic material, a plastic material capable of adhering to these two members will be injected between this layer and said longitudinal element so as to fill the space separating them, and said plane element will be kept in position until the injected plastic material solidifies.
  • the injection can be carried out for example through holes made in said planar longitudinal elements.
  • a plastic or metal strip or strip will be used as the flexible longitudinal element, while a metal profile, in particular a wing of an angle iron whose protruding wing will protrude, will be used as a rigid element outwards.
  • the flexible or rigid elements ensure the dimensional stability of the seat element in the plane of the lining by opposing the tensile forces exerted on the periphery of the lining, when its user sits on the seat.
  • This dimensional stability is of particular interest in the case of a multiple seat, in which the central part of the seat usually tends to sag under the weight of the users.
  • the deformation of the lining can be limited to the place occupied by each of the users by fixing a flexible element on the lining at the limit of each place.
  • Said flexible or rigid longitudinal elements may be made integral with the trim previously cut, along at least two opposite sides, the seat element thus produced then being fixed in position by making the flexible or rigid elements integral with the seat frame.
  • Flexible elements such as strips have the advantage of being able to be easily shaped to the profile of the corresponding elements of the seat frame, while the rigid elements must have a shape allowing them to match this profile.
  • At least two flexible or rigid elements, fitted along two opposite edges of the seat element, will be pinched between two rigidly assemblable parts of the seat frame.
  • these two parts of the seat frame will have a complementary profile and will be assembled by simple clipping, which will allow the mounting of the seat by unqualified personnel, without any recourse to sophisticated tools.
  • a preferred seat covering for the seat element according to the invention comprises a covering layer 1 of compact plastic material such as silicone elastomers, polyethylene , and compact polyvinyl chloride (PVC), for example with a density of the order of 1.18 to 1.30, with a Shore hardness of 40 to 98, this covering layer 1 being relatively thick, for example of around 5 mm.
  • compact plastic material such as silicone elastomers, polyethylene , and compact polyvinyl chloride (PVC)
  • PVC compact polyvinyl chloride
  • This cover layer 1 is secured, by means of an intermediate layer of foam of the same plastic material 3, to a network 4 formed by a continuous sheet of springs 5 in a spiral, with axes parallel to each other and to the cover layer 1.
  • These springs 5 can be produced for example using steel wires with a diameter of the order of 5 to 15 / 10ths of a mm. The diameter of the turns can then be between 10 and 20 mm.
  • the intermediate layer 3 can be made of plastic foam (PVC, silicone, polyethylene), with a density that can for example vary from 1 to 1.25.
  • this intermediate layer 3 is between g to the diameter of the turns of the springs 5, so that the turns are only partially coated in the plastic foam.
  • a fabric 6 can be attached to the cover layer 1.
  • the present invention aims to fix at least two longitudinal elements, respectively flexible and / or rigid, along two opposite lateral edges, for example parallel, of this lining, on the underside thereof, in order to produce a seat element .
  • Such longitudinal elements can naturally be arranged along two, three or four sides of such a quadrilateral lining.
  • the longitudinal elements 7 that are used are flexible elements, such as metal or plastic strips. These strips are applied against the external part of the spring ply 5 in a position contiguous to the edges of the lining and are held in this position while a bead of plastic 9 is injected through holes 8 from which they are drilled. intended to fill the gap separating the strip 7 from the layer 3 and to ensure the connection between this layer, the strips 7 and the springs 5. The strips 7 are then kept applied against the springs 5 until the plastic material hardens .
  • the positioning of the blades or strips 7 is carried out easily and the resulting seat element offers improved comfort to the user.
  • the flexible elements 7 described above can be replaced with rigid elements 10, for example in the form of an angle iron, of which a flat face 10a is made integral with the layer 3 and the sheet of springs 5 by a layer of plastic material 12.
  • the plastic material can be injected through holes 11 on the face 10 of the angle iron, so as to fill the gap separating this face from the layer 3.
  • the layer of plastic material may also be deposited beforehand on layer 3 in the vicinity of the edges of the sheet of springs 5, under a thickness such that these springs are embedded in the bead. Then apply the face 10a of the angle iron 10 against the springs and keep it in position until the plastic material has hardened.
  • the strips 7 can be glued with a bead of adhesive 9 against this layer 3 (FIG. 4) or applied against this layer 3 before polymerization of the plastic, of which it is made, during the manufacture of the lining.
  • a branch 10a of the angle iron can be glued against the layer 3 or embedded in it, during the manufacture of the lining, before polymerization of the plastic material of which it is made (FIG. 5).
  • Figures 6 to 8 illustrate a preferred form of attachment of the seat element according to the invention on a frame of this seat, Figures 6 and 7 showing the lower part of the seat and Figure 8 its top view.
  • the seat element 14 is, in this case, of the type shown in FIG. 1 and it therefore comprises metal strips 7 made integral by a bead of plastic material on the sides of the trim element.
  • the fixed part 15 comprises two parallel wings 19, comprising, on the faces arranged opposite, cleats 20, while the removable part 17 comprises two parallel wings 21, the edges of which can be engaged by clipping under the cleats 20, to lock the two parts 15 and 17 in the assembled position.
  • the periphery of the seat element 14 is deformed, so as to conform to the shape of the frames formed by the flanges 16 and the flanges 18, and is clamped firmly between these two edges, so as not to become detached, under the weight of a user, despite the deformations imposed on the lining itself.
  • the seat element thus fixed therefore has good dimensional stability, while allowing the lining of this to elastically deform, thereby offering users the desired flexibility and comfort.
  • the installation of the seat element can be carried out by non-specialized personnel, without the use of particular tools.
  • the seat completely conceals the structure of the seat element and the mounting system from view, and it is possible to give it any desired harmonious profile.
  • the present invention therefore provides a simple and easy to implement means for producing a flexible and comfortable seat element, from the seat upholstery already described by the Applicant in its previous patent applications.
