Definitions

  • the present invention relates to a cover for covering a seat cushion of a motor vehicle, such as a seat cushion for the front seat or rear seat, headrest or armrest, as well as to a method to dress such a cushion.
  • a seat cushion is usually made of a deformable material such as foam and is bounded by a top, sides and a bottom or bottom carried by a frame.
  • This foam is covered by a cap, such as a cover, in a flexible material.
  • This cap itself comprises a tray, a skirt and a flap extending mutually and which respectively cover, when the cap is in place on the cushion, the top thereof, at least a greater part of its sides and a corresponding strip from its underside.
  • the cushion and its frame are sandwiched between the tray and the flap of the cap.
  • An object of the invention is to provide a cap and a method for covering a cushion which dispenses with having over the entire contour defined by the free edges of the flap of such assembly profiles. This represents for mass production of seats both a saving in parts and a saving in considerable assembly time.
  • the present invention provides a cover for covering a motor vehicle seat cushion, cushion defined by a top, sides and a bottom, said cover itself comprising a tray, a skirt and a flap extending mutually and intended to cover respectively the top of the cushion, at least the largest part of its sides and a corresponding strip of its underside, at least the greatest length of the free edge of the flap being pleated and stretched so as to keep the cover in place on the cushion, characterized in that the pleating of the edge of the flap is carried out by sewing this edge in its previously pleated state, on an inextensible bead extending without folds along said edge.
  • the invention also provides a method for covering a seat cushion of a motor vehicle - cushion defined by a top, sides and a bottom - by a cap comprising a plate, a skirt and a flap extending mutually and intended to respectively cover the above the cushion, at least the greater part of its sides and a corresponding strip of its underside, at least the greater length of the free edge of the flap being pleated and stretched so as to keep the cover partly on the cushion, characterized in what, prior to the establishment of the cap on the cushion, it is sewn by pleating the edge of the flap on an inextensible cord which is extended without folds along said edge.
  • the seat of the front seat of a motor vehicle mainly comprises a frame 2 and a foam cushion 3.
  • the cushion 3 has a shape delimited by a top 3a, front sides, lateral and rear 3b and a bottom 3c by which the cushion 3 is carried on the frame 2.
  • This cushion 3 is covered by a cap 4.
  • This cap 4 mainly comprises a plate 5 which covers the top 3a and which defines with it the carrying surface on which the user is supported, as well as a skirt 6 attached by sewing on the edge of the plate 5 and which covers the front and lateral sides of the cushion 3.
  • the cover 4 also has a base 8 independent of this skirt 6, extending the rear edge of the plate 5 and intended to cover the rear flank of the cushion 3.
  • the skirt 6 is in place on the cushion, while the base 8 is shown in a position where it is not folded down on the underside 3c.
  • the skirt 6 is shaped with, over its entire periphery, a flap 7 whose edge is pleated and stretched by means 12 described below which maintain this flap 7 pressed against the bottom 3c and the frame 2.
  • this frame conventionally comprises a metal frame 9 between the sides of which extends at least one spacer 10, and zigzag springs 11 mounted between this spacer 10 and the frame 9.
  • Each of the two ends of the skirt 6 is extended by a rear wing 17 carrying the female part 17a of a press button.
  • This wing is folded laterally on the rear flank of the cushion 1 and thus ensures the complement of the coverings provided by the skirt 6 and the base 8.
  • the female part 17a cooperates with a complementary male part carried by the frame 2.
  • the pleating means 12 mainly comprise a cord 13 which is a braid of inextensible material extending along the edge of the flap 7 and on which this edge is sewn with pleating by two seam lines 14 ( Figure 4) stitched in the braid 13.
  • the folds or gathers, referenced by 15, thus formed on the edge of the flap 7 are distributed with a density which varies locally in the same direction as the curvature local of said edge.
  • the plate 5 of the seat is produced independently of the rest of the cap. It bears on its face destined to come in contact with the top 3a of the cushion 3 usual means intended to cooperate with complementary elements of the frame 2 to produce re-entrant lines L on the carrying surface of the seat cushion.
  • the skirt 6 is produced by cutting from a flexible material, such as a fabric-coated-plastic, two half-pieces 6 1 , 6 2 . These two half-pieces are assembled together by a seam line referenced by 18 in the figures.
  • the base 8 is cut from the same material. The different cutting contours correspond to the open projections of the shapes of the cushion portions 3 that the skirt 6 and the base 8 are intended to match.
  • the pleating machine is programmable for this purpose. It is fed simultaneously with the braid 13 and with the skirt 6 which it automatically pucks with a local percentage reduction in rating depending on the program it has in memory. The distribution law of folds is determined by preliminary tests on templates.
  • the skirt 6 thus preformed is then sewn onto the edge of the plate 5.
  • the braid 13 extends beyond the edge of the skirt 6 and at least one of its extensions is used for sewing between the plate 5 and the skirt 6.
  • the aforementioned pleating machine, and without interruption, sewing is performed without pleating of the skirt 6 on the edge of the contour of the plate 5 and on the braid 13, then the seam with pleating of the edge of the flap 7 of the skirt 6 on the braid 13.
  • This operation can moreover be carried out with a braid whose part on which the edge is sewn pleated flap is extended only on one side.
  • Another step consists in sewing on the free edge of the base 8 of the profiles 16, then in sewing this base 8 on the rear edge of the plate 5.
  • the establishment of the cap 4 on the cushion 3 begins with the assembly of the plate 5 on this cushion 3 either by gluing, or by molding in situ, or by conventional mechanical recall. The cap is then on the cushion 3 in the position shown in FIG. 4.
  • the cushion foam is mechanically compressed.
  • the skirt 6 is turned over like a sock on the foam and its pleated edge is placed against the frame 2.
  • the skirt 6 is then kept in tension between, on the one hand, the plate 5 resting on the foam and, on the other hand, the braid 13.
  • the outline delimited by this braid 13 is arranged inside that of the frame 9, so that the skirt 6 is shaped with a flap 7 extending from the outer edge of the frame 9 to edge pleated by the braid 13.
  • the cushion 3 is thus enclosed in the cover 4.
  • the rear wings 17 of the skirt 6 are then closed on the rear flank 3b of the cushion 3 and held by fitting the female parts 17a of the snaps on the complementary parts carried by the frame 2.
  • the cover 4 is then on the cushion 3 in his position shown in figure 2.
  • the base 8 is folded over the bottom that constitutes the frame 2 and held thereon by cooperation of the sections 16 with complementary portions of the frame 2 which receive them.
  • Positioning eyelets can be provided laterally at the rear of the frame 2 to cooperate with staples carried by the cover 4 and facilitate centering of the cover 4.
  • the final appearance of the covered seat 1 is that shown in FIG. 1.
  • the invention is not limited to the particular embodiment described but encompasses all the possible variants.
  • the braid can be replaced by any other cord stitched along the edge of the skirt flap, such as a ribbon or a similar continuous linear element.
  • the covered cushion can be without reinforcement. In the case of cushions other than seat cushions, the cover can be threaded without turning over the cushion.
