Definitions

  • the present invention relates to a vehicle seat comprising a shell, a decorative lining, a padding interposed between the shell and the lining, and inserts integral with the shell and used for fixing the seat on the vehicle.
  • the padding is placed on the shell while the lining is placed on the padding and fixed by its edges to the shell. Annoying slips between these elements can occur.
  • the present invention relates to a seat of the above type, characterized in that the lining, the padding and the inserts are an integral part of the shell, a fastening fabric being interposed between the padding and the shell.
  • the present invention also relates to a method of manufacturing this seat.
  • This process is characterized in that the padding is formed by injecting a foam between the lining and the hanging fabric, and in that the shell is formed by extrusion and blowing on the hanging fabric.
  • the formation of the padding can take place before that of the shell.
  • the shell is formed in a mold in which the assembly consisting of the lining, the padding and the hanging fabric was previously placed.
  • the formation of the padding can also take place after that of the shell.
  • the shell is formed in a mold in which a cap has been placed consisting of the lining and the hanging fabric previously assembled to one another.
  • the inserts can be fixed to the shell by placing these inserts in the bottom of the mold in which the shell is formed. They can also be fixed after formation of the shell by microfusion of the corresponding surfaces of the inserts and of the shell.
  • the seat has a padding 1 made of synthetic foam, for example polyurethane foam, which is interposed between an outer lining .2 and a hanging fabric 3, the assembly being an integral part of 'a blown shell 4 made for example of polypropylene copolymer or polyethylene of medium density.
  • the upper part 4a of the seat area of the shell has a decreasing thickness from its longitudinal edge towards the center, thus constituting a flexible fabric accompanying the foam 1 in its crushing and playing the role of elastic base.
  • the lower part 4b of this zone has studs 4c which limit the bending of the central portion of this part 4a and limit the sinking of the seat.
  • Hull 4 has ser inserts for attaching the seat to the vehicle and made of the same material as the shell, but reinforced with synthetic fibers.
  • these inserts are constituted by an external half-slide 5 and by a plate 6 which is provided on the internal side of the seat and on which supports 7 are fixed for a central slide 8.
  • the inserts 5 and 6 are an integral part of the shell.
  • the lining 2 and the hanging fabric 3 are made to overflow relative to the padding, as indicated in 2a and 3a.
  • the edges of the fabrics 2 and 3 are bonded beforehand by stitching or by high frequency welding.
  • the flexible part thus formed is placed in a mold comprising a die 11 and a punch 12, while maintaining the edges 2a and 3a of the fabrics in a sidewall clamp 13 (Figure 6).
  • the exterior profile of the punch 12 corresponds to the exterior profile desired for the exterior face of the shell.
  • the profile of the bottom of the matrix 11 corresponds to the profile that takes the external face of the flexible part when it is compressed under a pressure equal to the injection pressure of the shell, for example five bars, its internal face being fixed. This profile is indicated at 14 in Figure 5.
  • the die 11 and the punch 12 have on their edges cutting blades 11a and 12a respectively.
  • the inserts 5 and 6 are blocked in the mold at the places they must occupy on the shell.
  • the shell 4 is then extruded and blown into the mold 11-12.
  • the foam 1 is compressed by the blown material in the pasty state until the balance between the blowing pressure and the compression of the foam ( Figure 7).
  • the foam 1 On demolding, the blown material being hardened, the foam 1 returns to its initial shape ( Figure 8). The blades 11a and 12a cut the edges of the fabrics 2 and 3 which protruded from the foam. The seat is thus finished and ready to equip a motor vehicle.
  • the inserts 5 and 6 can be placed after formation of the shell by microfusion of the plastic by the mirror process.
  • the insert is pressed on the shell with the interposition of a hot wall, which melts the surfaces of the insert and the shell to the amount of the wall, this wall is removed and the insert is pressed. on the hull.
