Uppfinningen kan tillampas pa vindrutetorkarblad och pa torkarblad for bakrutor i fordon. TITLE Water additive for flat blade type wiper blades TECHNICAL FIELD OF THE INVENTION The present invention relates to a heater additive for wiper blades, and in particular for wiper blades of the so-called flat blade type. The invention can be applied to windscreen wiper blades and to wiper blades for rear windows in vehicles.

BAKGRUND OCH KAND TEKNIK 10 Torkarblad av flatbladtyp skiljer sig fran konventionella torkarblad bl.a. genotx: att de saknar utvandiga metallkomponenter. Medan det konventionella metallbladet innefattar en gummilist som i sin ryggsida uppbares av en ledad metallskena, uppvisar flatbladets ryggsida en integrerat forrnad spoiler avsedd att med fartvindens hjalp pressa flatbladet mot vindrutan. Flatbladets anvandning 'akar och de monteras ofta som originalblad i nya bilar. BACKGROUND AND BACKGROUND ART 10 Flat-blade type wiper blades differ from conventional wiper blades, e.g. genotx: that they lack external metal components. While the conventional metal blade comprises a rubber strip which is supported in its back side by an articulated metal rail, the back side of the flat blade has an integrated former spoiler intended to press the flat blade against the windscreen with the help of the wind. The use of flat blades' akar and they are often mounted as original blades in new cars.

Bada torkarbladstyperna besvaras emellertid av pafrysning i vintervaglag och vid underkylt regn. However, both types of wiper blades are answered by freezing in winter conditions and in freezing rain.

For att losa problemet med isbildning pa torkarblad liar i US 2 746 077 foreslagits en varmartillsats bestaende av en stansad skena av metall med hog elektrisk 20 resistans, vilken Or anslutbar till fordonets elsystem.

Narrnare bestamt ãr hallaren anordnad att ingripa i langsldpande spar i torkarbladets sidor och vcrkar ddrvid for att ovanifran pressa ned motstandsvarmeskenan mot torkarbladets rygg. I monterat 'age pa torkarbladet lOper den storm delen av motstandsvarm.eskenan utanfor sp'aren i torkarbladets sidor medan endast kortare partier vaxelvis insticker i namnda spar, En nackdel med derma kanda varrnartillsats Or att vdrme gar fOrlorad via de langsgaende sidoomraden av motstandsvarmeskenan som ej har kontakt med torka.rbladet. En annan nackdcl Or att varmartillsatsen enligt US 2 746 077 medfOr 30 en vasentlig okning av torkarbladets bredd och paverkar darFar sikten. Ytterligare en nackdel Or att dess jarnfOrelsevis kompliceracie utfoiuming medlar att Idv och annan smuts fastnar i torkarbladet, forsvarar montering/dernontering, och fOrdyrar tillverlmingen. 2 REDOGORELSE FOR UPPFINNINGEN Foreliggande uppfirming syftar till att anvisa en varmartillsats for torkarblad vilken undviker fiera av de nackdelar som Or forknippade med den kanda varmartillsatsen. 5 Syftet uppfylls i korthet genom en vannartillsats innefattande en plan motstandsvannefolie med parallellt lOpande, jamntjocka och jamnbreda langdsektioner som i var ande forbinds genom en respektive tvarsektion, vilken motstandsvarmefolie Or elektriskt anslutbar till fordonets elsystem och tillordnad en hallare uppvisande parallellt lOpande, jarnntjocka och jamnbreda skenor som Or inbordes forbindbara 10 genom ett antal mellankopplade bryggor, varvid bryggorna Or forrnade for att i monterat lage ph torkarbiadet stracka sig over torkarbladets rygg tran sida till sida av torkarbladet, medan den pa skenornas ovansida vilande varmefolien klguns mellari skena och en fran torkarbladsryggen vand horisontell ansats i torkarbladets sida, och vidare van i namnda skenor uppvisar en forhnjd eller uppvikt ytterkant 15 som hindrar vannefolien att rymrria ur sitt lage i torkarbladets sida. To solve the problem of icing on wiper blades in US 2,746,077, a heater additive has been proposed consisting of a punched rail of metal with high electrical resistance, which is connectable to the vehicle's electrical system. A holder punched from tadpoles is designed to engage with the wiper blade to hold the resistance warning rail on the wiper blade. When the holder is arranged, it is arranged to engage in longitudinal grooves in the sides of the wiper blade and thereby acts to press down the resistance heat rail against the back of the wiper blade from above. When mounted on the wiper blade, the storm part of the resistance heat rail runs outside the groove in the sides of the wiper blade while only shorter portions alternately insert into said grooves. A disadvantage of this known heater additive is that heat is lost via the longitudinal side regions of the resistance heat. has contact with torka.rbladet. Another disadvantage is that the heater additive according to US 2,746,077 causes a substantial increase in the width of the wiper blade and therefore affects the visibility. Another disadvantage is that its iron-complex complication means that Idv and other dirt get stuck in the wiper blade, defend assembly / disassembly, and make production more expensive. 2 DESCRIPTION OF THE INVENTION The present invention aims to provide a heater additive for wiper blades which avoids many of the disadvantages associated with the known heater additive. The object is briefly fulfilled by a water heater attachment comprising a flat resistance water foil with parallel running, evenly thick and evenly wide longitudinal sections which are connected in each direction by a respective cross-section, which resistance heating foil is electrically connectable to the vehicle electrical system and assigned a holder having parallel which Or is embedded in connectable 10 through a number of interconnected bridges, the bridges Or being formed to extend over the wiper blade back side to side of the wiper blade in mounted layer ph wiper blade, while the heat foil resting on the top of the rails clings between rail and a wiper blade back. shoulder in the side of the wiper blade, and further van in said rails has a pre-extended or folded outer edge 15 which prevents the water foil from escaping from its layer in the side of the wiper blade.

En pa detta salt utfonnad varmartillsats sakerstaller att ingen energi gar forlorad da all varme som alstras i motstandsvkinefolien overgar till torkarbladet och ingen varme forloras till omgivande luft. A heating additive invented on this salt ensures that no energy is lost as all the heat generated in the resistance coil foil transfers to the wiper blade and no heat is lost to the ambient air.

Genom att motstandsvarrnefolien Or fullstandigt infOlid i torkarbladets sida sker 20 ingen i5kning av torkarbladets bredd och varmartillsatsen paverkar saledes inte fOrarens sikt. Because the resistance protection foil is completely infolided in the side of the wiper blade, the width of the wiper blade does not increase and the heater addition thus does not affect the visor of the driver.

Genom ett konstruktivt fOrenklat utftirande Or uppfinningens vannartillsats enkel att montera och demontera fordonets forare, billig att framstalla, och enkel att halla ren i monterat lage. 25 Uppfmningens varmartillsats loser diirmed flera av de problem soul kan forvantas uppsta i den kanda varmartillsatsen for torkarblad. By means of a constructively simplified design, the water addition of the invention is easy to assemble and disassemble the vehicle's driver, inexpensive to manufacture, and easy to keep clean in assembled condition. The heater additive of the invention thus solves several of the problems that can be expected to arise in the known heater additive for wiper blades.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Fig. 1 shows, schematically, a wiper blade 1 of the flat blade type consisting of a foot unitary profile in which an embossing 2 is embedded which appears to give the wiper blade lateral stability. The cast profile may be formed of rubber or of a rubber compound, while the reinforcement 2, which may itself be hinged, usually contains metal. The wiper blade profile shown is arbitrarily selected but has representative mold elements such as a tip 3 designed to be swept asleep over the vehicle window in reciprocating sweeping motions, and a wiper blade back 4 designed as a spoiler which with the aid of the wind winds presses the wiper blade against the windshield. Narrinda functions typically cause the wiper blade profile to corrode to contain a free wiper blade ridge water horizontal shoulder 5 between the side stabilizing wiper blade ridge 4 and the sweeping, flexible tip 3. With "horizon bar" the welds should be fastened to the orientation shown in a wiper blade drawing The said shoulder 5 is used in the invention for mounting a warner attachment in a manner which will now be described.

Med hanvisning till Fig. 2 visas en varrncfolie 6 vilken via en elektrisk ledare 7 Ar anslutbar till fordonets elsystem. Vannefolier larnpliga fOr framstallning av varmefolien 6 Ar tiligAngliga I handeln. Sam ett exempel pa en lamplig varmefolie 30 kan namnas en 0,40 mm tjock motstandsvarmefolie for 12 eller 24 V AC eller DC, uppburen av en polyesterbarare av 0,1-0,2 mm tjocklek. Varniefolier av detta slag kan uppna en yttemperatur av ca 45° C, och har ett arbetstemperaturomrade am ea -45° till +95° C. Uppfinaingen Ar naturligtvis inte begransad till dessa 4 specifikationer hos en i marknaden farekommande varmefolie och som har anges endast som exempel. Referring to Fig. 2, a warning foil 6 is shown which is connectable to the vehicle's electrical system via an electrical conductor 7. Water foils are required for the production of the heating foil 6 Are available in the trade. An example of a suitable heat foil 30 is a 0.40 mm thick resistance heat foil for 12 or 24 V AC or DC, supported by a polyester carrier of 0.1-0.2 mm thickness. Warning foils of this kind can reach a surface temperature of about 45 ° C, and have a working temperature range am ea -45 ° to + 95 ° C. The invention is of course not limited to these 4 specifications of a marketable heating foil and which has been stated only as example.

Varmcfolien 6 ar formad for applicering i den horisontella ansatsen 5 i torkarbladets profil. For detta andamal bestar varmefolien 6 av tva. parallellt 5 lapande jamntjocka och jamnbreda langdsektioner 8, 9 som i var ande farbinds genom en respektive tvarsektion 10 och 11. En avlangdsektionerna 9 ar bruten och uppvisar dubbla fastaron 12 och 13 for fastladning av ledaren 7. Fastaronen 12, 13 kan genom limning vara fixerade pa en platta 14 av flexibelt material och med liten tiocklek, sasom en polyesterfolie. Varmefoliens 6 langd ãr anpassad till 10 torkarbladets lAngd, och avstAndet mellan de parallella langdsektionerna skall vasentligen motsvara torkarbladsprofdens bredd i hOjd med den horisontella ansatsen 5. The heating foil 6 is shaped for application in the horizontal shoulder 5 in the profile of the wiper blade. For this purpose, the heating foil 6 consists of two. parallel longitudinally thick and evenly wide longitudinal sections 8, 9 which are connected in each direction by a respective transverse section 10 and 11. The elongate sections 9 are broken and have double fasteners 12 and 13 for loading the conductor 7. The fasteners 12, 13 can be fixed by gluing on a plate 14 of flexible material and with a small thickness, such as a polyester foil. The length of the heating foil 6 is adapted to the length of the wiper blade, and the distance between the parallel longitudinal sections shall substantially correspond to the width of the wiper blade probes at the height of the horizontal shoulder 5.

Varmefolien 6 ar avsedd aft monteras pa torkarbladet 1 med hjalp av en for a.ndarnalet utformad hallare 15, se Fig. 3. Hal!area 15 innefattar parallellt lapande, 15 iamntjocka och ja'mnbreda skenor 16 och 17 vilka ãr tubordes fOrbindbara genom ett antal mellankopplade bryggor 18, varvid bryggoma 18 ar formade for att i monterat lage pa torkarbladet stracka sig Over torkarbladets ryg,g fran sida till sida av torkarbladet pa satt som frarngar narmare av Fig. 4. 1 det monterade raget lyfts saledes varmefolien 6 upg till anliggning mot den horisontella ansatsen S med stad 20 undenfran av hallarens skenor 16 och 17. For att varrnefolien 6 inte skall rymma ut ur halla.ren ãr skenorna i sin utsida formade med en respektive uppstaende kant 19, 20. The heating foil 6 is intended to be mounted on the wiper blade 1 by means of a pre-designed holder 15, see Fig. 3. The holding area 15 comprises parallel running, 15 thick and evenly wide rails 16 and 17 which are tubularly connected by a number of interconnected bridges 18, the bridges 18 being shaped to extend over the wiper blade back in a mounted layer on the wiper blade, going from side to side of the wiper blade in a manner which is closer to Fig. 4. In the mounted ridge the heating foil 6 is thus lifted up to abutment against the horizontal shoulder S with city 20 below the rails 16 and 17 of the holder. In order that the protective foil 6 does not escape from the holder, the rails are formed on the outside with a respective upright edge 19, 20.

Hallaren 15 ar lampligen tillverkad av svntetiskt material och kan vara gjuten genom ett stranggiutningsfarfarande. Efterbearbetning av den dutna profilen innefattar bortskarning av Overfladigt material mellan bryggorna 18, samt upptagning av ett hal 21 i en av brvggorna far genomforing av den elektriska ledaren 7.1 det gjutna utforandet reser sig bryggorna 18 saledes fran den uppstacnde kanten 19, 20 i hallarens sida. The holder 15 is suitably made of synthetic material and can be cast by a strand casting process. Finishing of the dull profile involves cutting of superficial material between the bridges 18, and taking up a hall 21 in one of the bridges before the electrical conductor 7.1 is passed through the cast design. The bridges 18 thus rise from the raised edge 19, 20 in the side of the hall.

Hallaren 15 Or foretradesvis utformad i anpa.ssning till torkarbladets profit sa att 30 torkarbladsryggen mottages med formanpassning under bryggorna 18. En fullstan.dig forrnanpassning mellan torkarbladets tygg 4 0th bryggorna 18 Or emellertid inte nadva.ndig. Genom att hallaren 15 kan utforas med en i utgangslaget underdimensionerad oppning Indian skenorna 16 och 17, varrned bryggorna maste bojas utat at sidorna vid montering, komrner bryggorna 18 att i monterat rage pa 35 torkarbladet utava en krainkraft i pilarnas F riktning enligt Fig. 4. The holder 15 is preferably designed in adaptation to the profit of the wiper blade so that the wiper blade back is received with shape adjustment under the bridges 18. However, a complete front fit between the wiper blade fabric 40th the bridges 18 is not necessary. Because the holder 15 can be made with an opening, which is undersized in the initial layer, the Indian rails 16 and 17, under which the bridges must be bent outwards at the sides during assembly, the bridges 18 will exert a crane force in the direction of the arrows F according to Fig. 4.

Separate bridges 22, acting as mounting brackets 22, may, where appropriate, be required to provide further fixation of the holder 15 and the heating foil 6, as shown in Fig. 5. In its 5 free spirits, the mounting bracket 22 is made with inboard opposite C-profiles designed to mount bearings 16 and 17 below the bearing and then clamp the holder 15 saint the water foil 6 resting in the rails of the holder to the horizontal shoulder 5 of the wiper blade profile.

Monteringsklamman 22 kan Iiksom hallaren 15 vara tillverkad i syntetmaterial och 10 dimensionerade for att i monterat lage utiiva en kla.mkraft i pilarnas F riktning i Fig. 5. Monteringskramman 22 kan alternativt vara utfOrd i mctall och deformerbar for att efter rnontering hallos pa plats av en bestacndc forrnanpassning till torkarbladet och till hallaren 15. Monteringsklanunan 22 uppvisar med fordel tillrAcklig bredd for att i forekommande fall tdcka och fixera de motande andarna av tva hallare 15 och 15', vilka fran varsin a.nde av torkarbla.det ãr inskjutbara fCr att mOtas i en skarv 23 (se streckad linje 23 under monteringsldamman 22 i Fig. 6). liallarens delar 15, 15' kan vara av sadan langd att de mots i narhet av torkarbladets torlc.ararmsfaste fOr att fixeras inbOrdes med hjalp av monteringsklamman 22. The mounting clamp 22 can, like the holder 15, be made of synthetic material and dimensioned to exert a clamping force in the mounted layer in the direction of the arrows in Fig. 5. The mounting clamp 22 can alternatively be made of metal and deformable to be held in place after installation. a permanent front fitting to the wiper blade and to the holder 15. The mounting clamp 22 advantageously has a sufficient width to cover and fix the receiving spirits of two holders 15 and 15 ', each from which the spirit of the wiper blade is slidable. is received in a joint 23 (see dashed line 23 under the mounting dam 22 in Fig. 6). The parts 15, 15 'of the liar can be of such a length that they are in proximity to the dryer arm attachment of the wiper blade to be fixed with the aid of the mounting clamp 22.
