Definitions
- the present invention relates to a ventilated seat element. More particularly, the present invention relates to passive ventilated vehicular seat element.
- Isocyanate-based polymers are known in the art. Generally, those of skill in the art understand isocyanate-based polymers to be polyurethanes, polyureas, polyisocyanurates and mixtures thereof.
- One of the conventional ways to produce a polyurethane foam is known as the "one-shot” technique.
- the isocyanate, a suitable polyol, a catalyst, water (which acts as a reactive "blowing” agent and can optionally be supplemented with one or more physical blowing agents) and other additives are mixed together at once using, for example, impingement mixing (e.g. high pressure).
- impingement mixing e.g. high pressure
- the polyol would be replaced with a suitable polyamine.
- a polyisocyanurate may result from cyclotrimerization of the isocyanate component.
- Urethane modified polyureas or polyisocyanurates are known in the art. In either scenario, the reactants would be intimately mixed very quickly using a suitable mixing technique.
- prepolymer Another technique for producing foamed isocyanate-based polymers is known as the "prepolymer” technique.
- a prepolymer is produced by reacting polyol and isocyanate (in the case of a polyurethane) in an inert atmosphere to form a liquid polymer terminated with reactive groups (e.g. isocyanates).
- the prepolymer is thoroughly mixed with a lower molecular weight polyol (in the case of producing a polyurethane) or a polyamine (in the case of producing a modified polyurea) in the presence of a curing agent and other additives, as needed.
- foamed isocyanate-based polymers are commonly used to produce parts used in vehicles. These include vehicular seats.
- a typical vehicular seat comprises a seat bottom and a seat back.
- the prior system simply provides a heated seat which is of little use to an occupant who seeks improved convenience in a warmer climate.
- this prior system is not designed to address the humidity microclimate that exists between the occupant of the seat and the seat surface. This creates occupant discomfort regardless of the temperature control achieved using either prior art approach.
- Another approach has involved molding into the seat element a conduit system that is connected to a motor that forces air, particularly heated and/or cooled air, through the conduit system.
- the forced air temperature can be regulated to provide what is known in the art as a climate control seat.
- United States patent 7,070,232 [Minegishi et al. (Minegishi)] teaches a so-called breathable seat that comprises a seat foam body formed of urethane foam and a three- dimensional network cushion body incorporated in that region of the seat body which bears a user's body weight, a seat cover having breathability and a seat pan.
- the cushion body is formed from a large number of continuous linear elements of thermal plastic resin. The linear elements are looped windingly so that their respective contact portions are fused together.
- the seat body is formed having so-called venting holes that pass through the urethane foam in its thickness direction. The venting holes communicate with the cushion body and apertures of the pan frame.
- the seat cover envelopes the seat body and the cushion body.
- a disadvantage with the approach taught by Minegishi is that it requires the use of two separate elements to achieve the so-called breathable seat.
- the urethane seat body must be configured to receive a cushion body which is not a foam material. This adds to the cost and complexity of producing a seat body and also suffers from the above-mentioned difficulties with recyclability of the seat body when it is discarded after use.
- German patent DEI 00 02 464 CI teaches a motor vehicle seat having a foamed core and at least one air duct extending in the core, an air-permeable seat cover, below which are air distribution layer is arranged made of material which is air permeable on all sides and with an air impermeable dividing layer between the foamed core and the air distribution layer.
- the core is foamed in situ and is encased on all sides by an air impermeable foam layer and the air duct is formed by inserting a core tube extending from the impermeable foam rear layer to the air impermeable front dividing layer.
- the seat described in this German patent publication suffers from the same difficulties as that described above for Minegishi, namely that the seat is expensive and complex to manufacture and is difficult to recycle after the product is discarded.
- United States patent application publication number US 2011/0169318 [Lem et al. (Lem)] teaches a passively air-conditioned motor vehicle seat comprising a breathable seat cover which has ventilation channels extending in the thickness direction. Each ventilation channel has at least one valve element for preventing the return flow of air in the direction from the B-surface of the seat to the A-surface of the seat.
- the valve element is constructed from the same material as the seat body.
- United States patent publication number US 2011/0241404 [Di Giusto et al. (Di Giusto)] teaches a vehicle supporting body having a padding which has a honeycomb body of elastic material and is covered with upholstery permeable to air and defining a user supporting surface.
- the cells of the honeycomb body extend along axis crosswise to the supporting surface and are open at the end.
- the seat supporting body comprises a number of connecting cells that are purportedly opened and closed automatically by valves in response to compression and decompression of the air in the cells - see Figures 2A-2D.
- Di Giusto suffers from the same disadvantages as described above with respect to Lem and Liou, namely that the temperature and humidity microclimate at the interface of the occupant of the seat and the A-surface of the seat is not improved appreciably.
- the approach in Di Giusto suffers from the disadvantages described above with respect to Minegishi, namely that the construction requires a number of heterogeneous elements which increases the cost and complexity of producing the seat and raises challenges with respect to recyclability.
- the present invention provides a vehicular seat element comprising a foam subtstrate, the foam substrate comprising an A-surface for contact by an occupant and a B-surface opposed to the A-surface, a central portion of the A-surface have a first surface area and comprising a plurality of channels, the central portion of the A-surface comprising an occupant contact portion having a second surface area, wherein the first surface area is greater than the second surface area, a plurality of apertures disposed in the plurality of channels, each aperture interconnecting the A-surface and the B-surface of the foam substrate.
- the present invention provides a A vehicular seat element comprising a foam subtstrate, the foam substrate comprising an A-surface for contact by an occupant and a B-surface opposed to the A-surface, a central portion of the A-surface have a first surface area and comprising an air manifold portion, the central portion of the A-surface comprising an occupant contact portion having a second surface area, wherein the first surface area is greater than the second surface area, a plurality of apertures disposed in the air manifold portion, each aperture interconnecting the A-surface and the B-surface of the foam substrate, the foam substrate configured to create a bellows effect of air in one or both of the air manifold potion when the occupant contact portion is successively compressed and de-compressed.
- the present inventors have discovered a novel passively ventilated vehicular seat element which affords various improvements to the prior art discussed above. These improvements are proved from the provision of the combination of a plurality of channels in the A-surface of the seat element where the channels are coupled to one or more apertures that extend to the B-surface of the seat element.
- the channels extend an area of the A-surface which is larger than the contact area between the occupant of the seat and the A-surface. In other words, the channels extend beyond where a typical occupant would contact the A-surface of the seat element.
- channels are not particularly restricted provided that it allows for lateral movement of air with respect to the positioning of the apertures that connect the channels to the B-surface of the seat element.
- a specific channel pattern which provides the improvements referred to above is set out in more detail below, it is to be understood that other channel patterns can be used.
- the point is the channel must provide the function of achieving lateral movement of air with respect to the A-surface of the seat element and the aperture that is connected to that channel and the B-surface of the seat element.
- WO 2006/102751 International Publication Number WO 2006/102751 [San Miguel et al. (San Miguel)].
- a typical vehicular seat element it is common to have side bolster portions on a opposed sides of the foam seat element and a central region for contact with the occupant. While it is preferred to dispose the channel pattern over substantially the entire central portion of the seat element, the main requirement is that the channel pattern be disposed in a central area of the A-surface that exceeds a predetermined area configured for normal contact with the occupant of the seat element. This ensures that air can be circulated beyond the area of contact between the occupant and the A-surface of the seat element.
- a vehicular seat element As used throughout the specification, this term is intended to cover both a vehicular seat cushion (the bottom portion of the seat) and a vehicular seat back (the back portion of a vehicular seat).
- the seat element is produced from an isocyanate-based polymer foam, more preferably a polyurethane foam, in which the channel pattern has been directly molded into a portion of the A-surface of the foam element. This facilitates production of the passively ventilated seat element and improves recyclability of the seat after it is discarded.
- a molded polyurethane foam pad is produced in one process step. In other words, no post processing is required.
- the foam pad has a series of through holes that connect the bottom or B-surface of the foam pad with a top or a A-surface of the foam pad.
- the A-surface has a series of channels and a number of through holes disposed in the channels.
- a decorative trim cover is placed on top of the pad and is selected to have a medium to high level of permeability (e.g., fabric, perforated leather, etc.) in the region of the ventilation channels to allow for air flow to the occupant.
- the series of channels acts a distribution manifold for air to be moved laterally with respect to the A-surface of the foam pad and also through the holes in the seat pad to allow for circulation of air.
- the through holes in the foam provide a pass for air to flow from the B-surface of the foam pad to the A-surface of the foam pad, and vice versa.
- This air flow is further promoted by compressing and decompressing of the foam by the mass of the occupant while the vehicle is in motion. This compression and decompression of the foam creates a so-called bellows effect to push or pull air through the vehicular seat.
- the series of channels molded in the A-surface of the foam pad form a manifold that enhances air distribution by providing multiple paths for the air flow around (not just beneath) the occupant and through the seat.
- the above improvements can be achieved without significantly (or otherwise) affecting the comfort properties of the seat element.
- Figure 1 illustrates a perspective view of a vehicular seat incorporating a preferred embodiment of the present ventilated seat element in the form of a vehicular seat back in combination with a vehicular seat cushion;
- Figure 2 illustrates an enlarged perspective view of a portion of a vehicular seat cushion illustrated in Figure 1
- Figure 3 illustrates a front elevation of a portion of the vehicular seat cushion illustrated in Figure 1 ;
- Figure 4 illustrates a sectional view along the lines 4-4 in Figure 3 with the additional inclusion of an occupant and a trim cover on the ventilated seat element;
- Figures 5 and 6 illustrate alternate embodiments of channel patterns that may be used in place of or in addition to the channel pattern illustrated in Figure 2 and 3.
- Vehicular seat 10 comprises a seat cushion element 100 and a seat back element 200.
- seat cushion element 100 and seat back element 200 are shown in Figure 1 without a trim cover and without the channel pattern (the latter is shown in Figures 2-4) and discussed in more detail below.
- Seat cushion element 100 comprises a pair of side bolsters 105,110.
- the A-surface of seat cushion element 100 comprises a central portion 1 15 containing a series of apertures (described in more detail below) that traverse from the A-surface of seat cushion element 100 to the B-surface.
- seating portion 120 Disposed within central portion 115 is a seating portion 120 shown in hatched outline.
- Seating portion 120 is designed to represent a portion of the A-surface of seat cushion element 100 intended for the occupant. The point is central portion 115 of the A-surface of seat cushion element 100 is larger than seating portion 120.
- portion 115 comprises a series of channels 125 and ridge portions 130.
- Channels 125 are in a generally jagged or Z-shaped configuration.
- Disposed periodically in channels 125 are a series of apertures 135 which are shown ghosted as in Figure 2 since they are obscured by ridges 130.
- Arrow X in Figures 1 and 2 shows a orientation of channels 125 and ridges 130 with respect to vehicular seat 100 - this is a preferred embodiment only and other relative orientations of channels 125 and ridges 130 are possible.
- FIG. 3 With reference to Figure 3, there is a shown a front elevation of the section of portion 1 15 shown in Figure 2. The placement of apertures 135 can be clearly seen in Figure 3.
- foam element 102 comprising channels 125, ridges 130 and apertures 135 can be seen.
- foam element 102 is made from polyurethane foam.
- channels 125, ridges 130 and apertures 135 are disposed in central portion 115 of seat cushion element 1 10 which extends beyond seating portion 120 that is adapted to contact the occupant.
- the three variations consisted of representative seat elements with no modifications or a flat surface (comparative #1), a flat surface with only through holes connecting the A-surface and B-surface - i.e., no channel pattern in A-surface (comparative #2) and the seat element as illustrated Figure 3, which includes channels, ridges and aperatures (invention).
- the mass or indentor used had a contact surface area less than the surface area of the A-surface in which the combination of channels, ridges and aperatures was disposed in the seat element as illustrated in Figure 3.
- Seat cushion element 100 and seat back element 200 may be produced using a conventional mold configured to provide a combination of channels 120 and ridges 130 (see, for example, San Miguel referred to above), and apertures 135 (see, for example, German patent DE 100 02 464 CI).
