Definitions

  • the present invention relates a trim cover attachment system.
  • the present invention relates to a seat and particularly, to a passenger seat for use in vehicles, which incorporates the trim cover attachment system.
  • Passenger seats in vehicles are typically fabricated from a foam (usually polyurethane) material which is molded into the desired shape and covered with an appropriate trim cover.
  • the foamed material is selected to provide passenger comfort by providing a resilient seat and the trim cover is selected to provide the desired aesthetic properties. It is known in the art that, while the resiliency of the foamed material in the seat provides passenger comfort, it does not provide the necessary structural strength for the seat. This necessitates additional reinforcement of the seat to provide the degree of structural strength required to ensure proper mounting of the seat within the vehicle and proper support of anti-submarine elements, if present. Accordingly, prior art vehicular seats typically include a perimeter frame of metal which strengthens the seat.
  • support rails are typically mounted across the metal frame to stiffen the frame and to provide a suitable attachment point for the means used to anchor the seat to the vehicle.
  • the metal frame and/or support rails are substantially completely embedded in the foam material when the seat is molded.
  • the metal frame will further comprise a plurality of apertures or other means for attaching a trim cover to the seat.
  • a passenger seat comprising: a frame element, vehicle anchorage means connected to the frame element, a seat body comprising a resilient material fixed with respect to the frame element and trim cover attachment means, the trim cover attachment means comprising a relatively high density, rigid foam member having a groove disposed in a surface thereof, the groove capable of receiving connection means comprised in a trim cover.
  • a "tongue and groove” connection system may be utilized to affix a trim cover to the frame element of the passenger seat.
  • the combination of the tongue and the groove provides an interference fit of sufficient strength that the trim cover will not readily detach from the frame element of the passenger seat.
  • the precise design of groove 15 is not particularly restricted and, in some cases, may be dictated by the design of tongue member 40.
  • the present invention provides a passenger seat comprising: a frame element; vehicle anchorage means connected to the frame element; a seat body comprising a resilient material fixed with respect to the frame element and a groove disposed in a surface thereof; a trim cover disposed over at least a portion of the seat body; and trim cover attachment means attached to the trim cover and comprising a tongue for insertion in the groove, the tongue operable between a closed position during insertion in the groove and an open position after insertion in the groove.
  • the present invention provides a padded element comprising a seat body comprising a resilient material and a groove disposed in a surface thereof; a trim cover disposed over at least a portion of the seat body; and trim cover attachment means attached to the trim cover and comprising a tongue for insertion in the groove, the tongue operable between a closed position during insertion in the groove and an open position after insertion in the groove.
  • the present invention provides a trim cover system for a padded element, the trim cover system comprising: a trim cover; and trim cover attachment means attached to the trim cover and comprising a tongue for insertion in a groove in the padded element, the tongue operable between a closed position during insertion in the groove and an open position after insertion in the groove.
  • Figures 1-3 illustrate production of an embodiment of the present passenger seat.
  • an aspect of the present invention relates to passenger seat.
  • the term "seat” is intended to have its conventional meaning and includes one or both of a cushion (i.e., the portion of the seat on which the occupant sits) and a back or back rest (i.e., the portion of the seat which supports the back of the occupant).
  • a "seat” includes both a cushion and a back (or backrest).
  • the term “seat” includes a cushion, a back (or back rest) or a unit construction comprising a cushion and a back (or backrest).
  • the frame element may be constructed of a foam having an indentation force deflection at 25% deflection in the range of from about 150 to about 4000 pounds, more preferably from about 500 to about 2500 pounds, most preferably from about 900 to about 2000 pounds, when measured pursuant to ASTM 3574-
  • the frame element of a polyurethane foam it is preferred to construct the frame element of a polyurethane foam. More preferably, the polyurethane foam of frame element 20 preferably has a specific gravity of less than about 0.40, more preferably in the range of from about 0.10 to about 0.25.
  • the liquid foamable polyurethane composition used to produce frame element 20 has a free rise density of from about one to about twenty pounds per cubic foot, more preferably from about two to about eight pounds per cubic foot. For most molded foams, this would give use to a foam core having a density in the range of from about 1.5 to about 24 pcf, more preferably from about 2.5 to about 12 pcf.
  • Non-limiting and preferred examples of suitable polyurethane foams for use in producing frame element are conventional rigid polyurethane foams
  • polyurethane foam suitable for use in producing such a frame element and having the requisite characteristics may be produced from the following general non-limiting formulation:
  • Suitable polymer polyols, polyols and isocyanates are described in United States patents 3,304,273, 3,383,351, 3,523,093, 3,939,106 and 4,134,610, Belgian patent 788,115, Canadian Patent 785,835 and "Polymer/Polyols, aNew Class of Polyurethane Intermediate", Kuryla, W.C. et al., J. Cellular Plastics, March (1966). See also, “Flexible Polyurethane Foam” by Herrington et al. (1991).
  • the preferred polyurethane foam suitable for use in frame element 20 may be produced from the following formulation: Component Amount
  • Isocyanate 6 Adequate quantity for an index of from about
  • the frame element may be a conventional metal frame - see, for example, the Burchi #1 Patents and the Burchi #2 Patents for a discussion of the use of conventional metal frames.
  • the present passenger seat further comprises a resilient body in which the frame element is embedded.
  • the resilient body may be constructed of any material conventionally useful in the production of seats.
  • the resilient body may be made of a foam or non-foam material.
  • Non-limiting examples of useful non- foam materials include fibers matrices such as horse hair, organic fibers and the like.
  • the resilient body may also be constructed of any suitable foam material.
  • the resilient body is constructed of a relatively low density, resilient foam, more preferably a polyurethane foam. Polyurethane foams useful for this purpose are well known in the art.
  • the present passenger seat further comprises a groove disposed in the surface of the seat body.
  • this groove may be disposed directly into the seat body or it may be disposed in the frame element (made of foam or metal) which is embedded in the seat body. In either case, the groove is disposed (directly or indirectly) in the seat body.
  • the purpose of the groove is to receive a tongue which is attached to the trim cover.
  • a trim cover 10 has attached to it a fabric portion 15 which functions as a retainer. Attached to fabric portion 15 is a tongue 20. Tongue 20 comprises a body portion 25 and a locking portion 30. Locking portion 30 comprises a pair of projections 35,40.
  • trim covered 10 is attached to a seat body 50 made of a conventional resilient polyurethane foam.
  • Seat body 50 has disposed therein a groove 55.
  • Groove 55 comprises an elongate passageway 60 having an open first end and connected to a trench 65.
  • trench 65 comprises a pair of shoulders 70,75.
  • groove 55 is disposed directly in resilient seat body 50 and the frame element is not illustrated.
  • groove 55 could be disposed in a foam or metal frame element without departing from the spirit and scope of the present invention.
  • locking portion 30 Once locking portion 30 enters trench 65, projection 35,40 of locking portion 30 are biased to an open position and are locked into place against shoulders 70,75 in trench 65.
