Definitions

  • ABSTRACT When vehicle seats are covered with a synthetic plastics material there are problems in hot weather because they do not soak up perspiration as would natural leather. On long journeys or on hot days, therefore,
  • the seat cushion as a pump which expells air as it is depressed by the movements caused by the person sitting on the seat or vehicle movements and the expelled air is forced out through the front face of the back rest of the seat.
  • This invention relates to vehicle seats, particularly car seats.
  • the seat coverings are generally made from synthetic plastics sheeting or leathercloth. This leads to difficulty, particularly in hot weather, because these synthetic materials do not absorb and soak'up perspiration like real leather seat coverings would do.
  • the seat covering itself can be given a deep embossment or channels may be provided in the shape of the seats. These expedients give a reasonable amount of ventilation over the surface of the seat covering'in the regions in contact with the body of the person sitting on the seat. Even in temperate climates, however, these expedients are not sufficient to prevent areas of the clothes in contact with the seat from becoming wet and sticky on hot days or on long journeys.
  • a car seat which comprises a cover of synthetic plastics sheet material over a resilient filling carried on a rigid frame or base, the sheet material of the cover having small perforations therethrough at least some of which are in communication with pump means, the pump means comprising a plurality of bellows fitted within the filling, the outlets of the bellows being in communication with one or more perforations through the covers so that vibrations and similar movements occuring during motion of the vehicle and/or body movements of a person sitting on the seat cause changes in the volumes of the bellows thereby causingair to be pumped through the perforations in communication withthe bellows.
  • the pumping action caused by body movements and movements of the car substantially increases the amount of ventilation and so keeps the person sitting on the seat cooler and drier.
  • the seat cushion can be provided with one or more individual bellows similar to those shown and described in our US. Pat. No. 3,506,308 which are arranged to suck air in through small holes in the upper surface of I the cushion, suitable ducts being provided to transmit the air to be expelled at the back rest of the seat.
  • the whole seat cushion acts as the pump or' bellows membersince then even very slight depression of the top surface of the seat cushion will then displace a comparatively large volume of air.
  • the seat cushion has a surface area of 1 400 sqare inches, e.g., inches by 20 inches, and its whole surface is depressed by as little as one-sixteenth inch, the volume of air displaced is cubic inches.
  • the seat can be ofany convenient construction.
  • the cover for the seat cushion pad back rest have both been made by vacuum forming, for
  • the covers formed inthis way have then-been filed with a foamable mixture, e.g, a polyurethane foam, which is foamed in situ so becoming bonded to the cover, the foam being of the open-celled type so that air can be displaced from the foam when the seat cushion is compressed.
  • a foamable mixture e.g, a polyurethane foam, which is foamed in situ so becoming bonded to the cover, the foam being of the open-celled type so that air can be displaced from the foam when the seat cushion is compressed.
  • a number of small holes are provided in the upper-surface of the seat cushion through which air can be sucked as the cushion becomes less depressed due to body movements or jolts caused by the motion of the car.
  • These holes are desirably near the centre of the area in contact with the body of the person on the seat and coincide with a number of elongated depressions or recesses, preferably interconnected, in the shape of the upper surface of the seat cushion which provide a network of passages extending over the region of the cushion in contact with the person and along which aircan pass to the holes when someone is sitting on the seat.
  • the back rest of the seat is also preferably provided with similar vent holes coinciding with elongated depressions or recesses so that the air expelled through these holes is spread over the area of the face of the back rest of the seat in contact with the person sitting on the seat.
  • FIG. 1 is a perspective view of the seat according to the invention
  • FIG. 2 is an upright cross-section taken centrally of the seat
  • FIG. 3 is an enlarged sectional detail.
  • the car seat 10 shown in the drawings has a seat cushion 12 and a back rest or squab 14 joined to one another by metal plates 16.
  • the seat cushion 12 consists of a cover 20 of an embossed plasticizedpolyvinyl chloride in which has been foamed in situ an open-celled polyurethane foam 22.
  • This seat cushion 12 has been made in the manner described in our United Kingdom Pat. No. 1,232,381. This cushion 12 sits in a metal frame 24.
  • the back rest or squab 14 comprises of a padded cushion 30 consisting of a cover 31 and padding foam 32 and is of similar construction to the seat cushion 12, a surrounding metal frame 33, and a rear sealing sheet 34 of embossed plasticized polyvinyl chloride welded to the shaped cover 31.
  • the top face of the cushion 12 has formed in it a number of channels 40 which are arranged in a crisscross pattern. These channels 40 are formed in the area which will normally be in contact with a person sitting on the seat so as to ensure excellent ventilation in that area between the person and the cover.
  • the front face of the cushion 30 has formed in its face similar channels 42, again formed in a criss-cross pattern in the area likely to be in contact with a person sitting on the seat 10.
  • passages 52 are provided through the cover 20 at the junction of transverse extending channels 40 and below these holes are passages 52 through the foam 22 leading to a common passage 54.
  • hinged flaps 56 (FIG. 3) which act as non-return valves and so ensure that air only passes in through the holes 50.
  • the common passage 54 leads to an outlet 58 from the seat cushion l2.
  • a hinged flap valve 70 is provided across the inlet 66.
  • Brass eyelets 72 define the holes 50 and 60 to prevent.
  • the covers 20 and 31 are also preferably deeply embossed so improving the comfort of the seat.
  • a vehicle seat comprising:
  • a resilient seat cushion having a top face on which a passenger sits
  • a resilient back rest having a front face arranged. to support the back of a passenger sitting on said seat cushion
  • a vehicle seat according to claim 1 further comprising non return valve means to prevent substantial egress of air from said top face of said seat cushion and substantial return of air from said back rest to said seat cushion.
  • a vehicle seat according to claim 2 further comprising at least one bellows unit positioned within said seat cushion, each bellows unit having an air inlet in communication with a small hole through said top face of said seat cushion, and an air outlet in communication with said means for the passage of air to said back rest.
  • said seat cushion comprises a shaped cover of synthetic plastics material, a resilient fill of open-celled foam material, and a number of small holes in said top face of said seat cushion, whereby depression of said top face causes air to be expelled from said foam through said air outlet means.
  • a vehicle seat according to claim 4 further comprising passages through said foam leading from said small holes, a common passage to which said passages through said foam lead, flap valves immediately below said small holes to prevent expulsion of air through said holes, said common passage leading to said air outlet means from said seat cushion.
  • a vehicle according to claim 5 further comprising elongated depressions in said top face of said seat cushion, said small holes being in alignment with said elongated depressions.
  • a vehicle seat according to claim 5 in which said elongated depressions are interconnected.
  • a vehicle seat according to claim 6 further comprising elongated depressions in said front face of said seat cushion and small holes through said front face in alignment with said depressions, said small holes constituting said air outlets through said front face of said back rest.
  • a vehicle seat according to claim 8 in which said back rest comprises a shaped cover of synthetic plastics material, a resilient interior covered by said shaped cover, and passages through said resilient interior leading to said small holes through said front face of said back rest, a common passage leading from said air outlet means from said seat cover to said passages through said resilient interior.
  • a vehicle seat according to claim 9 further comprsing a flap valve in said common passage to prevent substantial return of air from said back rest to said seat cushion.
  • a vehicle seat comprising:
  • a resilient seat cushion having a top face on which a passenger sits, 'b. a shaped covering for said cushion made of synthetic plastics material,
  • a resilient back rest having a front face arranged to support the back of a passenger sitting on said seat cushion
