Description
Oppfinnelsen angår en' varmematte av den type som er The invention relates to a heating mat of the type that is
angitt i innledningen til patentkrav 1. stated in the introduction to patent claim 1.
Oppfinnelsen er primært beregnet for anvendelse som bilvarmesete, men andre anvendelsesområder, såsom oppvarmede klesplagg, f.eks. sko,'eller som akkumulatorbatterivarmere, The invention is primarily intended for use as a heated car seat, but other areas of application, such as heated garments, e.g. shoes,'or as accumulator battery heaters,
er også1 tenkbare. I- sistnevnte tilfelle anbringes matten rundt batteriet og elektrodene forbindes med hver sin av batteriets poler. are also1 conceivable. In the latter case, the mat is placed around the battery and the electrodes are connected to each of the battery's poles.
Bilvarmeseter består vanligvis av en gjennom hele setet forløpende, meanderformet sloyfe av elektrisk motstandsmateriale, hvilken sloyfe er innstopt i et elektrisk isolerende, men godt varmeledende materiale. Sloyfen er med sine ender koblet til bilbatteriet. Sådanne bilvarmeseter har den ulempe Heated car seats usually consist of a meander-shaped sloyfe of electrical resistance material running through the entire seat, which sloyfe is stuffed in an electrically insulating but well heat-conducting material. The ends of the cable are connected to the car battery. Such heated car seats have the disadvantage
at det kan oppstå> brudd.på sloyfen, hvorved setet blir ubrukelig for sitt formål. Denne ulempe elimineres ved- at bilvarmesetet ifolge oppfinnelsen har de kjennetegn som er angitt.i patentkrav 1. Ved at hele setet består av et motstandsmateriale i hvilket that there may be a break in the sloyf, whereby the seat becomes unusable for its purpose. This disadvantage is eliminated by the fact that the heated car seat according to the invention has the characteristics stated in patent claim 1. By the fact that the entire seat consists of a resistance material in which
strommen fordeler seg' i det vesentlige homogent i området, mellom elektrodene, får. forskjellige mekanisk oppståtte skader på setet i hovedsaken ingen innvirkning på setets varmefunksjon. the current distributes itself essentially homogeneously in the area between the electrodes. various mechanically caused damages to the seat essentially no effect on the seat's heating function.
Dersom man velger et motstandsmateriale som har en ganske hoy positiv te.mperaturkoef f isient, i det minste ved If you choose a resistance material that has a fairly high positive temperature coefficient, at least wood
temperaturer over et på forhånd bestemt temperaturnivå, oker mattens motstand innenfor dette temperaturområde, og dette temperatures above a predetermined temperature level increase the mat's resistance within this temperature range, and this
betyr at den tilveiebragte effekt synker ved hoyere temperaturer, means that the provided effect decreases at higher temperatures,
slik at matten ikke kan nå en temperatur over.et visst bestemt temperaturnivå på grunn av yarmeavledning. Dette innebærer at matten ikke kan bli overoppvarmet. so that the mat cannot reach a temperature above.a certain determined temperature level due to yarme dissipation. This means that the mat cannot be overheated.
Det finnes riktignok allerede kjente varmematter hvor en plate av en elektrisk .ledende gummiblanding med på motstående sider innlagte elektroder kan kobles til en spen-ningskilde. for elektrisk oppvarming, men ved disse anordninger dannes elektrodene av hver sin i motstandsmaterialet innlagt, trådformet, leder, hvilket medforer en forholdsvis hoy over-gangsmotstand mellom den trådformede leder og motstandsmaterialet. Dette er ugunstig, da det herved fås en ujevn oppvarming og det kreves en forholdsvis hoy matespenning. Sammensetningen It is true that there are already known heating mats where a plate of an electrically conductive rubber mixture with electrodes placed on opposite sides can be connected to a voltage source. for electric heating, but with these devices the electrodes are each formed by a wire-shaped conductor embedded in the resistance material, which results in a relatively high transition resistance between the wire-shaped conductor and the resistance material. This is disadvantageous, as this results in uneven heating and requires a relatively high supply voltage. The composition
av motstandsmaterialet i disse allerede kjente varmematter er dessuten slik at mattene er beregnet for tilkobling til nett-spenning. Disse matter anvendes heller ikke som bilvarmeseter. of the resistance material in these already known heating mats is also such that the mats are intended for connection to mains voltage. These mats are also not used as heated car seats.
Særlig ved bilvarmeseter der en lavspenning fra bilbatteriet kobles over elektrodene, og der man dessuten er inter-?-ressert i å holde effektforbruket på et' så lavt. nivå som mulig., utgjor opptredende overgangsmotst.and mellom elektrodene og motstandsmaterialet en stor ulempe. En stor'overgangsmotstand kan også medfore at hovedsakelig bare området rundt elektrodene varmes opp, og at det derved ikke oppnås noen vesentlig oppvarming av setet. Elektrodenes utforming bor derfor være slik at denne ulempe ikke oppstår. Dessuten skal materialet i elektrodene og motstandsmaterialet være slik avpasset til hverandre at det ikke dannes noen kjemisk forening mellom disse av en sådan karakter at et isolerende eller dårlig ledende skikt tilveiebringes ved. elektrodene. Ved. prover har et motstandsmateriale av folgende beskaffenhet vist seg å gi de onskede egenskaper for dette materiale: Especially with heated car seats where a low voltage from the car battery is connected across the electrodes, and where you are also interested in keeping the power consumption as low as possible. level as possible, the resulting transition resistance between the electrodes and the resistance material constitutes a major disadvantage. A large transition resistance can also mean that mainly only the area around the electrodes is heated, and that no significant heating of the seat is thereby achieved. The design of the electrodes must therefore be such that this disadvantage does not occur. Furthermore, the material in the electrodes and the resistance material must be matched to each other in such a way that no chemical union is formed between them of such a nature that an insulating or poorly conductive layer is provided. the electrodes. By. samples, a resistance material of the following nature has been shown to provide the desired properties for this material:
I denne forbindelse kan vulkaniseringsmidd.elet er-stattes med andre for polymeren.passende midler. Elektroder av messing eller fosforbronse har vist seg å gi god samvirkning med dette materiale, da disse materialer ikke så lett danner kjemisk forbindelse med det i vulkaniseringsmiddelet inngående svovel, som ville være tilfellet med rent kobber. Prover er også blitt utfort med elektroder av gull, rsolv og aluminium, men messing eller fosforbronse har vist seg å være det over-legent beste materiale for ovennevnte formål. In this connection, the vulcanizing agent can be replaced with other agents suitable for the polymer. Electrodes of brass or phosphor bronze have been shown to work well with this material, as these materials do not so easily form a chemical connection with the sulfur contained in the vulcanizing agent, as would be the case with pure copper. Tests have also been carried out with electrodes of gold, rsolv and aluminium, but brass or phosphor bronze have been found to be by far the best material for the above purposes.
Varmematten ifolge oppfinnelsen fremstilles hensiktsmessig slik at elektrodene- innlegges, mellom to ark av motstandsmaterialet langs to motstående sider av disse ark, hvoretter hele anordningen oppvarmes under hoyt trykk slik at elektrodene innvulkaniseres i motstandsmaterialet og arkene sammenvulkani-seres. The heating mat according to the invention is suitably manufactured so that the electrodes are inserted between two sheets of the resistance material along two opposite sides of these sheets, after which the entire device is heated under high pressure so that the electrodes are vulcanized in the resistance material and the sheets are vulcanized together.
Platen av motstandsmateriale behover ikke å være homogen, men kan omfatte perforeringer, eksempelvis i form av mellom elektrodene forlopende, gjennomgående, langstrakte spor som fortrinnsvis slutter i en avstand fra elektrodene. Ved at en viss luftveksling tillates å skje gjennom disse perforeringer, kan disse bidra til at anvendelseskomforten okes når varmematten The plate of resistance material does not need to be homogeneous, but can include perforations, for example in the form of continuous, elongated tracks extending between the electrodes which preferably end at a distance from the electrodes. By allowing a certain amount of air exchange to take place through these perforations, these can help to increase the comfort of use when the heating mat
ifolge oppfinnelsen f.eks., anvendes for bilvarmeseter eller klesplagg. according to the invention, for example, is used for heated car seats or clothing.
Oppfinnelsen skal beskrives nærmere i det folgende under henvisning til tegningen, der fig. 1 viser'et delvis gjennomskåret perspektivbilde av et bilvarmesete omfattende en varmematte ifolge oppfinnelsen med skjematisk vist tilkobling til bilbatteriet, fig. 2 viser et delvis gjennomskåret del- The invention shall be described in more detail in the following with reference to the drawing, where fig. 1 shows a partially cut-through perspective view of a heated car seat comprising a heating mat according to the invention with schematically shown connection to the car battery, fig. 2 shows a partially cut-away part

■ På fig. 1 er vist et bilva.rme.sete ifolge oppfinnelsen plasert på et bilsete 1 av vanlig forekommende type. Bilvarmesetet kan selvsagt-være utfort i ett.stykke med bilsetet ved fremstilling av dette. Bilvarmesetet består av to deler, nemlig ryggstøtten 2.og setet 3?og_hver del består i den viste utforelsesform av to ovenpå hverandre anbragte , .sammensveisede eller sammenlimte ark h og 5 av et elektrisk ledende motstandsmateriale. Dette materiale bor være elastisk og formbart og inneholder fortrinnsvis en blanding av gummi og grafitt. ■ In fig. 1 shows a heated car seat according to the invention placed on a car seat 1 of the usual type. The heated car seat can of course be made in one piece with the car seat when it is manufactured. The heated car seat consists of two parts, namely the backrest 2 and the seat 3? and each part in the embodiment shown consists of two sheets h and 5 of an electrically conductive resistance material placed on top of each other, welded together or glued together. This material should be elastic and malleable and preferably contains a mixture of rubber and graphite.
Langs hver sin motstående side av hver del. er et par elektroder 6, 7 innlagt mellom arkene. Hver elektrode består av et finmasket nett,:slik som vist oppskåret ved 6, eller av et perforert bånd, slik som vist oppskåret ved 7>og av et elektrisk godt ledende, boyelig -materiale , såsom messing eller, fosforbronse. Motstandsmaterialet er hensiktsmessig på sin overside overtrukket med et elektrisk isolerende belegg for å hindre strommen mellom elektrodene i å gå gjennom kroppen på Along opposite sides of each part. is a pair of electrodes 6, 7 inserted between the sheets. Each electrode consists of a fine-mesh net, as shown cut at 6, or of a perforated band, as shown cut at 7, and of an electrically conductive, bendable material, such as brass or phosphor bronze. The resistance material is suitably coated on its upper side with an electrically insulating coating to prevent the current between the electrodes from passing through the body of
