Definitions

  • abreathable covering cooperate with a self-skinned cushion to provide ventilation.
  • auxiliary cushions do notgive the ap pearance of being an integral part of an upholstered seat and are thus, to many, not as aesthetically pleasing as a cushion that appears to be anintegral unit.
  • a seat cushion having a cast skin is formed so that a large recess is incorporated into the seating surface.
  • the recess is preferably shallow and has side walls which are generally perpendicular to the surface of the cushion so as to form a nest for snugly capturing an insert member placed therein.
  • the insert member may be be changed quite formed of the same material as the cast skin but in a different color so as to provide contrast, or it may be formed of a porous material which provides a degree of ventilation.
  • the inserts are preferably attached to the cushions by fasteners which are not visible but which may be readily fastened or unfastened. In an embodiment wherein the cushions are molded to include ventilating tubes between the recess area and the rear of the cushion, the fasteners may conveniently pass through said tubes and be anchored behind the cushion.
  • FIG. 1 is a partially cut away and partially exploded perspective view showing a pair of seat cushions of the present invention and one type of insert member and fastening therefor:
  • FIG. 2 is a partial side sectional view of the seat back cushion of FIG. 1 in association with a modified form of insert and attachment means with the various parts shown in the positions they assume just prior to the assembly of the insert to the seat;
  • FIG. 3 is similar to FIG. 2 but shows modified forms of the insert member, fastening means and seat cushion of FIG. 2;
  • FIG. 4 is similar to FIG. 2 but shows an additional modification
  • FIGS. 5 and 6 are front and side views respectively of the ventilated fastener retainer plate used in the modification shown in FIG. 4.
  • FIG. 7 shows a slight modification of the FIG. 4 arrangement
  • FIG. 8 is a view similar to FIG. 2 showing yet another modification but with the seat cushion and insert members in assembled relationship;
  • FIG. 9 is a side sectional view of the cushion and insert members of FIG. 4 in combination with other seat structure which includes ventilating passages and a blower device.
  • a seat 10 has a back cushion I2 and a bottom cushion l4 pivotally attached to each other by means of fastener means 18.
  • the cushions 12, 14 are covered with a cast skin 20 which is preferably formed of a tough durable plastic. Molded to the inside of the cast cover 20 is a filler 22 which preferably comprises an expanded foam material such as polyurethane.
  • a seat pan or frame member 24 may be molded into the foam material 22.
  • the cushions 12, 14, are formed with recessed areas 28, 28 which are defined by a generally flat recess surface 30 and side walls 32 which are generally perpendicular to the plane of the seating surface. Since the materials which are most desirable for the casting of the skin or cover 20 are usually non-porous and thus offer no opportunity for the seat cushions to breathe, a plurality of tubular openings 34 are preferably provided in the cushions which extend from the surface 30 of the recess area 28 to the rear of the cushion.
  • an insert member indicated generally at 38 which may include an interior bent wire frame 40 forgiving rigidity to the insert member and for providing a plurality of support locations 40a to which fasteners 50 may be attached for holding the insert 38 to the cushion 12.
  • the front and back surfaces 42, 44 of the insert 38 may be made of a porous covering material such as cloth.
  • the cover layers 42, 44 may be backed up by fillers such as jute padding which provide some measure of softness to the insert while preventing the support frame 40 from rubbing directly on the cover layers.
  • Recess 28' requires a larger insert than recess 28.
  • the insert 38 is preferably maintained within the recessed area 28 by fastening means such as springs 50 which may be looped around the frame 40a of the insert 38 at one ofits ends and be retained at its other end by fastening means such as a washer 54 and a pin or clip member 56.
  • fastening means such as springs 50 which may be looped around the frame 40a of the insert 38 at one ofits ends and be retained at its other end by fastening means such as a washer 54 and a pin or clip member 56.
  • Such a fastening means is invisible from the front of the seat cushion and retains the insert 38 against unauthorized removal while permitting the insert to be removed when desired by removing pin 56 or by pulling out on insert 38 sufficiently to enable spring 50 to be disconnected.
  • FIG. 2 shows an insert member indicated generally at 138 having outer and inner surface coverings 142, 144.
  • the insert 138 is attached to the cushion 112 by means of a plurality of plug-like fastener members 150 which have large flanges 152 which may be bonded or otherwise fastened to the surface 144 so as to be held in alignment with the holes 134 in cushion 112.
  • the pluglike fasteners 150 include friction engaging members such as rings 154 which are adapted to dig into portions of the cover material 120 which extend into the holes 134 so as to provide firm retention of the insert member.
  • the fasteners 150 preferably have a hole 156 extending through them in order to permit air to pass freely between the interior of the insert member 138 and through the ventilating holes 134.
  • the insert member indicated generally at 238 is attached to the cushion 212 by means of hook and loop fastener members 250, 252 such as those sold under the trademark Velcro".
  • This type of fastening means is particularly convenient when the seat cushion 212 does not include ventilating holes.
  • FIG. 4 shows a modification of the invention wherein the insert member indicated generally at 338 is fastened to the cushion 312 by a spring-like fastener member 350 which is anchored to the rear of the cushion 312 by a flanged grommet member 354 and a ventilating grid plate 356 (FIGS. and 6) having an anchor or loop portion 358 to which the spring 350 is attached and including a plurality of ventilating holes 360 which permit air to pass through the tubular opening 334.
  • the internal construction of the insert 338 shown in this modification includes a pair of outer surface layers 342 and 344 formed of porous material and a center portion 340 formed of coiled wire.
  • the coiled wire 340 gives a resilient support to the insert 338, permits air circulation therein, and provides convenient connec- '450.
  • the insert 438 may include grommet or eyelet members 446 for properly positioning the buttons 452 and protecting the surfaces 442, 444 from tearing.
  • the insert 438 may be covered with different materials on each side in order to increase its usefulness. For example, one side of the insert could be covered with a po rous material which could be made to face outwardly in the summertime to permit ventilation through the insert interior and the porous covering whereas the opposite side of the insert could be surfaced with a heat reflective material which would provide warmth when facing outwardly in the wintertime by reflecting body heat.
  • one side of the insert could be covered with a material such as terrycloth to provide an absorbent and cool surface for use when the vehicle containing the seat is to be driven to the beach or left in the sun while the opposite side could be covered with a more attractive looking material.
  • a material such as terrycloth to provide an absorbent and cool surface for use when the vehicle containing the seat is to be driven to the beach or left in the sun while the opposite side could be covered with a more attractive looking material.
  • FIG. 9 shows the insert 338 and cushion structure 312 of FIG. 4 in association with a seat back member 360 which includes ventilating channels 365 which interconnect the ventilating holes 334 through a conduit such as a flexible pipe 366 to a blower member 368 which can either blow air into the inserts and against the seat occupant or withdraw it from the insert.
  • a seat back member 360 which includes ventilating channels 365 which interconnect the ventilating holes 334 through a conduit such as a flexible pipe 366 to a blower member 368 which can either blow air into the inserts and against the seat occupant or withdraw it from the insert.
  • a blower member 368 which can either blow air into the inserts and against the seat occupant or withdraw it from the insert.
  • many other types of heating and cooling means could be connected to the seat and insert to make the seat more comfortable.
  • a ventilated seat construction comprising a molded cushion having a cast skin cover and a molded resilient filler portion, said filler portion being integrally bonded to said cover, said cast cover including at least one recessed portion on its external seating surface, a porous insert member having a cover of a material different from said cast skin cover, said porous insert member being adapted to be engaged by a seat occupant and having external dimensions corresponding to the dimensions of said recessed portion so as to be receivable in said recessed portion and retained thereby against sideways movement, and cooperating fastening means on said molded cushion and on said insert member for maintaining said insert member within said recessed portion.
