Description

35 40 7713250-4 2 andra tilledaren 6 via en termostatanordning 7 för att efter anslut- ning till en strömkälla hålla elementets temperatur på önskad nivå. 77 40 7713250-4 2 the second conductor 6 via a thermostat device 7 to keep the temperature of the element at the desired level after connection to a power source.

I praktiken är det lämpligt att metallfolieslingan l är innesluten gmellan två likadana, inbördes vidhäftade plastfolier för bildande av ett lätthanterligt, elektriskt isolerat folieelement, som på enkelt sätt kan anordnas innanför ytskiktet hos ett mjukt eller töjbart element, vars yta skall uppvärmas. I första hand är uppfinningen tänkt att tillämpas vid säten i-olika typer av fordon och farkoster, men givetvis kan anordningen enligt uppfinningen användas i alla sammanhang,.där man önskar snabbt och likformigt uppvärma en mjuk eller töjbar yta. ' d Såsom vidare framgår av ritningen är meanderslingorna 1 så orienterade, att de förlöper i olika, mot varandra vinkelräta rikt- ningar, nämligen med de längre raka slingdelarna parallella med rektangelns långsidor vid elementets båda ändavsnitt och parallella med kortsidorna i elementets centrala parti. Härigenom kan metall- folieslingan l töjas i betydande grad i godtyckliga riktningar utan skaderisk. För att säkerställa att bärskiktet 2 vid en dylik töjning ej brister på sådana ställen, att metallfolien l får övertaga belast- ningen, har slitsar 8 utstansats i de fria områdena bredvid och mellan meanderslingorna. De yttre slitsarna 8a är raka och parallella med de intilliggande slingpartierna. De inre slitsarna är väsentligen L-formiga (8b), T-formiga (8c) samt 1 några fall korsformiga (Bd) och i ett fall rakt (Be), varvid intilliggande slitsändar har mellan- liggande, såsom brottanvisningar tjänande materialbryggor 9,10. Vid töjning av elementet i godtyckliga riktningar kommer dessa i olika företrädesvis vinkelräta rader liggande materialbryggor 9,10 att brista först, varvid förlängda slitsar bildas, dock utan risk för skador på metallfolieslingan l.In practice, it is suitable that the metal foil loop 1 is enclosed between two identical, mutually adhered plastic foils to form an easy-to-handle, electrically insulated foil element, which can easily be arranged inside the surface layer of a soft or extensible element, the surface of which is to be heated. In the first place, the invention is intended to be applied to seats in different types of vehicles and vehicles, but of course the device according to the invention can be used in all contexts where it is desired to quickly and uniformly heat a soft or extensible surface. As further appears from the drawing, the meander loops 1 are oriented so that they run in different, perpendicular directions to each other, namely with the longer straight loop parts parallel to the long sides of the rectangle at both end sections of the element and parallel to the short sides in the central part of the element. In this way, the metal foil loop 1 can be stretched to a significant degree in arbitrary directions without risk of injury. In order to ensure that the support layer 2 does not break in such places in such an elongation that the metal foil 1 is allowed to take over the load, slots 8 have been punched out in the free areas next to and between the meander loops. The outer slots 8a are straight and parallel to the adjacent loop portions. The inner slits are essentially L-shaped (8b), T-shaped (8c) and in some cases cross-shaped (Bd) and in one case straight (Be), the adjacent slitting ends having intermediate material bridges 9,10 serving as fracture instructions. . When stretching the element in arbitrary directions, these material bridges 9,10 lying in different preferably perpendicular rows will first rupture, whereby elongated slits are formed, but without risk of damage to the metal foil loop 1.

De utstansade slitsarna 8 tjänar även som luftgenomsläppandv hål i det eljest gastäta folieelementet, och detta är av väsentlig betydelse vid permanent montering i fordonsäten o.d., nämligen för ökning av sittkomforten, vilken även befrämjas av att folieslementet tack vara slitsarna får större böjlighet. Likaså kan det flexibla folieelementet böjas helt ljudlöst. 1 Folieelementets ytterkantpartier kan vid behov förstärkas med draghållfasta armeringstrâdar eller enbart genom ökning av materi- altjockleken. Alternativt eller dessutom kan det av metallfolie ocn slitsade plastbärskikt bestående folieelementet anbringas, exempel- vis genom fastlimning, på ett med gles struktur utformat monterings- 77132504 Skikt, företrädesvis i form av ett plastnät eller en textilväv, vars flexibilitet och töjbarhet är större än folieelementets. Även andra modifieringar kan genomföras av fackmannen inom ramen för den i efterföljande patentkrav l presenterade uppfinningstanken.The punched slots 8 also serve as air-permeable holes in the otherwise gas-tight foil element, and this is of essential importance for permanent mounting in vehicle seats etc., namely for increasing seating comfort, which is also promoted by the foil element having greater flexibility thanks to the slots. Likewise, the flexible foil element can be bent completely silently. 1 The outer edge portions of the foil element can, if necessary, be reinforced with tensile-strength reinforcement threads or only by increasing the material thickness. Alternatively or in addition, the foil element consisting of metal foil and slotted plastic carrier layer can be applied, for example by gluing, to a mounting layer designed with a sparse structure, preferably in the form of a plastic net or a textile fabric, whose flexibility and extensibility are greater than the foil element. Other modifications may also be made by those skilled in the art within the scope of the inventive concept presented in the appended claim 1.

Förutom vid farkost- och fordonssäten kan uppfinningen med fördel tillämpas exempelvis vid uppvärmbara klädesplagg,kuddar, filtar, sovsäckar, mm.In addition to vehicle and vehicle seats, the invention can be advantageously applied, for example, to heatable garments, pillows, blankets, sleeping bags, etc.
