Definitions

  • the present invention relates in general to the heating and cooling of the seats of a motor vehicle.
  • a seat with temperature control including a mass of padding with a layered structure and heat-exchange means for heating or cooling the seat.
  • Such a seat is known, e.g. from DE-A-33 06 871.
  • Figure 6 is a partially-sectioned perspective view of the squab according to an embodiment of the invention.
  • a motor vehicle seat is constituted by a squab 1 including a layer 6 which has a resilient response and is sufficiently soft to ensure the comfort of the occupant; superposed on the layer 6 is a layer 5 with a "plastic" type of response, that is, a layer which can deform according to the load acting on it and can therefore increase the surface used to support the body weight of the occupant and at the same time improve its restraint, is superposed on the layer 6; this plastic layer can return to its undeformed condition some time after the removal of the load.
  • a squab 1 including a layer 6 which has a resilient response and is sufficiently soft to ensure the comfort of the occupant; superposed on the layer 6 is a layer 5 with a "plastic" type of response, that is, a layer which can deform according to the load acting on it and can therefore increase the surface used to support the body weight of the occupant and at the same time improve its restraint, is superposed on the layer 6; this plastic layer can return to its undeformed condition some time after the removal of the
  • a further surface layer (of resilient type) is glued on top of the "plastic" layer 5 and includes longitudinal grooves 3 defined by ribs 2 of the outer surface layer.
  • the outer surface layer includes two lateral restraining pads 7.
  • Longitudinal heat-exchange elements 4 are housed in the grooves (see Figure 2) and may be either electrical resistances or tubes containing a cooling or heating fluid.
  • the outer layer of padding is squashed so as to enable the heat-exchange elements 4 to come very close to the surface of the squab and thus eliminate the aforementioned insulation effects which lead to the low thermal efficiency of the controlled-temperature seat.
  • the outer layer including the grooves 3 could also be made of compact foam if design requirements call for the outermost layer of the squab 1 to have such a characteristic.
  • longitudinal grooves 3 enables the heat-exchange elements 4 to be maintained easily and also to be replaced quickly in the event of breakage.
  • an intermediate layer 10 which has the function of supporting the heat-exchange elements 4, to be inserted between the plastic layer 5 and the outer layer.
  • the squab has a surface covering layer 9 formed with longitudinal cavities and ribs, as described above; resilient foam (shown by shading in Figure 5) is subsequently injected into the grooves thus formed.
  • This composite, surface covering layer 9 and the resilient foam padding in the ribs 2 is then glued to the underlying plastic layer 5, with or without the interposition of the intermediate support layer 10.
  • Figure 6 shows the whole squab structure, in which the base 12 (made of mesh or a rigid tray) and the header tube 11 which connects the tubes 4 arranged longitudinally within the grooves 3 are also shown.
