Definitions

  • the present invention relates to a flexible lining for seats.
  • the invention also relates to a method of manufacturing such a lining and its use for lining a seat frame.
  • the external face of this trim can be possibly covered with a flexible outer sheet of decorative material, for example fabric.
  • An object of the invention is, therefore, to provide a variant of the above-mentioned trim, which lends itself to easy attachment, with reduced tools, to a seat frame of any type, and to a easy production of concave or convex shapes.
  • Another object of the invention is to provide such a seat covering, which lends itself to the use of a covering sheet made of a noble material, allowing its possible use for equipping seats with interior furniture.
  • the invention also aims to provide a simple and inexpensive method of manufacturing such a lining.
  • the invention finally aims to propose the use of such a trim to equip a seat frame, which uses a particularly simple method of attachment to this frame.
  • the subject of the invention is a filling for a seat of the type described above, this filling being characterized in that the flexible external sheet covering the covering layer projects laterally with respect to this layer of sufficient width to be folded down on a seat support and made integral with it.
  • the constituent material of this flexible outer sheet may be fabric, plastic, leather, velvet and, more generally, any flexible decorative material used to cover seats.
  • the upholstery according to the invention may be fixed in a particularly simple manner on a seat frame by a process consisting in appropriately cutting the projecting part of the flexible outer covering sheet, in laterally folding this part on the seat frame and to make it integral by any means known in the art, in particular by gluing or stapling.
  • the covering layer can also be polymerized before applying the flexible sheet of decorative material thereto and then sticking this flexible sheet to the covering layer made of compact polymer resulting from this polymerization.
  • the lining thus produced can be easily fixed on a suitable support by simple gluing or stapling on the latter of the projecting part of the flexible sheet. It also lends itself to an excellent finish of the filling thus produced, with perfect continuity of the flexible covering sheet.
  • the manufacture of the lining is therefore divided into several phases.
  • the vandal-resistant part is made, which includes the metal sheet, the expanded layer and possibly the compact layer. This set once made will be cut to the desired shape.
  • Notches can be locally made to allow, after a possible bonding, to realize curved, concave or convex shapes.
  • a flexible external sheet of decorative material is reported.
  • This last sheet will be of dimensions greater than that of the sheet previously cut and possibly formed, in order to obtain at the necessary places a free edge which makes it possible to fix, in whole or in part of its periphery, the complex thus obtained on its support.
  • the connection between the flexible outer sheet of decorative material and the previously cut web can be done either by coating as in the previous case, or by application of the connecting material by means of a projection (for example with a spray gun) or a mechanical deposit.
  • the polymerization of the different layers can be done either all at once or in several stages. It can be carried out for each of the components by heating or by adding a catalyst.
  • the phases of the above process can be carried out in a discontinuous sequence.
  • the lining according to the invention comprises a layer 1 of an expanded plastic, in which are partially embedded helical springs 2 interleaved.
  • a layer 3 of a compact polymer is integral with the face of the layer 1 of expanded plastic opposite to that by which the springs 2 protrude.
  • a flexible sheet 4 of a covering material which extends laterally from the layer 3 of a length sufficient to allow the attachment of the lining on a seat support suitable, by gluing or stapling overhanging parts on this support, after elimination by cutting of the corner parts such as 5 or others and folding of the side parts 6.
  • the layer 1 of expanded plastic may, in known manner, consist of a foam of polyvinyl chloride, silicone, polyethylene or similar materials.
  • Layer 3 of compact polymer may also be made of polyvinyl chloride, polyethylene or silicone, or similar materials.
  • Figures 2 and 3 show how a packing according to the invention can be produced in a simple manner.
  • FIG. 2 a layer of a mixture of a liquid monomer, a blowing agent and a layer of a non-adherent support, such as transfer paper, is deposited on a sheet 8.
  • a polymerization catalyst the layer of helical springs 2 is partially drowned in this layer so that the springs emerge from the layer 1 thus deposited, and polymerization and expansion of the polymer are caused.
  • the sheet 8 is then removed from the assembly thus produced and, on the face of the layer 1 opposite the springs 2, a layer of a monomer and of a polymerization catalyst is applied and this is caused to polymerize. monomer to obtain layer 3 of the compact polymer adhering to layer 1 of expanded plastic.
  • the flexible outer sheet 4 (fabric or other) will advantageously be cut in the manner shown in FIG. 4, that is to say by cutting and eliminating at right angles the corner part of this sheet and leaving a rounded notch 10 in the part applied to the anti-vandalism support and corresponding to the rounded part thereof (see FIG. 1).
