  • Number 1 in Fig.s 1, 2 and 3 indicates an automobile fitted with a system for air conditioning seats 2.
  • the said system comprises a fluid source and a duct for feeding the said fluid inside a seat cover 3 constituting either the upholstery or an outer covering fitted over the upholstery on the said seat 2.
  • a seat cover 3 constituting either the upholstery or an outer covering fitted over the upholstery on the said seat 2.
  • the said fluid is fed towards the part of the user's body resting on the seat cover, for maintaining the said body part at a given temperature.
  • seat cover 3 comprises two prismatic box cases 4 and 5 designed to rest respectively on the seat and backrest portions of seat 2.
  • Cases 4 and 5 are preferably formed from impermeable synthetic fabric, and present a bottom wall 6, two long side walls 7, two short side walls 8, and a top wall 9 in which is formed a large rectangular through opening 11 designed to support the user's body and'covered with a layer 12 of permeable synthetic or vegetable fabric.
  • Seat cover 3 also comprises a rectangular header 13, in turn, comprising a first portion 14 housed inside case 4 next to side wall 8 forming one end of seat cover 3; a second portion 15, the first part of which is housed inside case 4 next to one of side walls 7, and the second part of which is housed inside case 5 next to side wall 7 corresponding with the former; a third portion 16 housed inside case 5 next to side wall 8 forming one end of seat cover 3; and a fourth portion 17 having, like the said second portion 15, a first part housed inside case 5 next to one of side walls 7, and a second part housed inside case 4 next to side wall 7 corresponding with the former.
  • the said header 13 presents a number of radial holes 21 ( Figure 3) distributed along its entire length.
  • the inside surface of bottom walls 6 is fitted with a layer 23, preferably of polyvinyl chloride, whereas the inside surface of top walls 9 is fitted with a layer 19 of woven-non-woven fabric for filtering and diffusing the air flow. Between layers 23 and 19, there is inserted a middle layer 22 formed from a honeycomb compound highly permeable by air.
  • Fig.s 4, 5 and 6 show three preferred embodiments of the system, depending on the type of automobile it is installed on.
  • the part of the system common to all three embodiments comprises a duct 26, a first end of which is connected to a four-way distributor 27 from which extend two ducts 28 and 31 connected to the respective unions 18 of seat covers 3 on front seats 2, and a duct 32 connected to a three-way distributor ( Figure 5) from which extend a further two ducts relative to seat covers 3 on rear seats 2.
  • Ducts 28, 31 and 32 are fitted with a throttle valve 34 for regulating the air supply to seat covers 3.
  • the component parts on the system are shown schematically, for the sake of simplicity, as are the automobile parts which have been modified for installing the system covered by the present invention.
  • the system shown in Fig.4, and indicated as a whole by 20, comprises an air distributor 24, which may consist of the existing fan normally incorporated in the air conditioning circuit on automobile 1. From distributor 24, there extends a union 25 connected to a second end of duct 26.
  • air supply may be regulated either by throttle valves 34, or by means, on distributor 24, commonly used on automobiles and not shown for the sake of simplicity.
  • system 20 may also provide for regulating the temperature of the air supplied to seat covers 3.
  • Number 35 in Fig.5 indicates a compressor forming part of an air conditioning circuit on automobile 1, here shown only partially.
  • compressor 35 is fitted onto a rotary shaft 36, onto which is also fitted a pulley 37 connected by belt 38 to a pulley 41 on the drive shaft, and to a pulley 42 on the output shaft of the alternator.
  • a first duct 43 is fitted with a radiator (not shown) for cooling the air inside the passenger compartment, and a second duct 44 with a radiator (not shown) for cooling the engine.
  • the system for air conditioning seat covers 3, as shown in Fig.5 and indicated as a whole by 29, comprises an air intake 45 possibly fitted with a filter and from which extend two ducts 46 connected, by means of a three-way valve 47, to an inlet duct 48 on a compressor 51 fitted onto shaft 36. From compressor 51, there extends a duct 26 for connecting seat covers 3 as already described.
  • compressor 51 is a rotary type
  • system 29 is preferably provided with a maximum pressure valve 52 on duct 26.
  • System 29 comprises two heat exchangers 53 fitted onto ducts 43 and 44 and through which run respective ducts 46.
  • ducts 46 downstream from respective exchangers 53 supply hot and cold air respectively, which may be drawn off selectively by valve 47 and mixed to produce a single stream of air at a given temperature.
  • the system shown in Fig.6, and indicated as a whole by 49 comprises an air intake 54 possibly fitted with a filter and connected, via duct 55, to a rotary power compressor 56 on the output shaft 57 of a d.c. motor 58 supplied by the battery (not shown) on automobile 1 by means of an electric cable 61.
  • the said cable 61 is fitted with a voltage regulator 62, for regulating the speed of power compressor 56, and with a safety fuse 63.
  • From the said power compressor 56 there extends duct 26 fitted with maximum pressure valve 52.
  • Power compressor 56 may be re- placed by a power blower, also supplied by the automobile battery. All the air supply ducts are preferably formed from plastic, in particular, polyvinyl chloride.
  • Air intakes 45 and 54 shown schematically in Fig.s 4 and 5, may be installed at the front or rear of automobile 1.
  • ducts 28, 31 and 32 supply air into header 13 which, via radial holes 21, feeds it towards honeycomb layer 22, and through layers 19 and 12 towards the part of the body resting on the said layer 12.
  • the existing air conditioning or ventilation circuit on automobile 1, in which case, it is possible to regulate both the air supply and the amount of hot and cold air supplied to seat cover 3.
  • Operation of system 20 in Fig.4 consists quite simply in drawing off from distributor 24 a given amount of air for supplying seat covers 3.
  • the drive shaft, via belt 38 turns pulley 37 and, therefore, also shaft 36.
  • the said shaft 36 is also fitted with an additional compressor 51 which draws off air from air intake 45 and supplies it to seat covers 3. As it flows through exchangers 53, the said air yields or absorbs heat from the gas flowing inside ducts 43 and 44. Valve 47 provides for mixing the said hot and cold air and, therefore, for supplying seat covers 3 with air of a given temperature.
  • System 49 in Fig.6 enables seat covers 3 to be used on automobiles with no ventilation or air conditioning circuit.
  • System 49 in fact, presents a d.c. motor 58 supplied by the battery on automobile 1 and controlling operation of power compressor 56, which draws off air from intake 54 and supplies it to seat covers 3.
  • air may be supplied differently to seat cover 3, by employing component parts on the existing ventilation or air conditioning circuit on automobile 1.
  • a rotary shaft may be assembled and fitted with a pulley and compressor.
  • the said pulley may be connected by means of a belt to the pulley on the drive shaft, and to the pulley on the alternator shaft of automobile I.
  • the compressor may be connected, at one end, to an air intake such as 45 and 54 and, at the other end, to duct 26.
  • Fluid may be fed inside seat cover 3 in any number of ways.
  • a centre header may be provided on the connection between the backrest and the seat portion of seat 2.
  • a number of ducts may extend towards both the seat portion and backrest covers, the said ducts having a number of radial holes, similar to holes 21, along their entire length.
  • the shape and material of seat cover 3 may also be other than as described herein. Water may be used in place of air, in which case, the automobile must be provided with an appropriate tank, and seat cover 3 acts as an ordinary heat exchanger between the water circuit inside and the part of the user's body resting on seat cover 3. Obviously, on such a system, both seat cover 3 and the water circuit inside the same must be waterproof.
  • the said circuit inside seat cover 3 may be formed in any number of ways, the only difference, as compared with the air systems already described, being that the water system must be provided with a duct for feeding water from seat cover 3 back to the tank. Instead of a compressor, the said water system will, of course, be provided with a pump for drawing off water from the tank and supplying it to seat cover 3. On the water system also, water may be fed through heat exchangers as shown in Fig.5.
