Abstract

The present invention relates to a third sunscreen (1) that is located in the middle of the windscreen (10) upper portion, in the screening strip (3) of the vehicle windscreen (10) and is defined from above by bottom edge of a ceramic print (2) in the windscreen (10) upper portion (10), from the side by projection of tilted main mechanical screens of the driver and front passenger onto the vehicle windscreen (10) and from below by a transition line (15) of the vehicle windscreen (10) screening strip (3). It is comprised of a colored screening layer (12) based on PVB (polyvinyl butyral) film (11, 11') that is interposed between the first glass layer (13) of the windscreen (10) and the second glass layer (13) of the windscreen (10), whereby said colored screening layer (12) is transparent with a color shade, and light transmittance thereof is equal or if need may be variable but not greater than 25 percent all over the sunscreen (1) surface.

Description

Třetí sluneční clonaThird sun visor

Oblast technikyTechnical field

Vynález se týká třetí sluneční clony, umístěné v horní oblasti čelního skla automobilu mezi clonou řidiče a spolujezdce.BACKGROUND OF THE INVENTION The present invention relates to a third sun visor located in the upper region of a car windshield between a driver and a passenger visor.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

Dosud se proti oslnění sluncem v oblasti nad zpětným zrcátkem používá buď mechanická clona, nebo clona, vyrobená keramickým potiskem na skle. Mechanická clona má dvě různá provedení. První varianta je samostatný plastový díl, který je umístěn v obložení stropu a v případě potřeby se vyklopí a zakryje oblast nad vnitřním zpětným zrcátkem. Druhou variantou je řešení, kdy je clona na zakrytí prostoru nad zpětným zrcátkem součástí dvou hlavních slunečních clon proti oslnění. Toto řešení je omezeno tvarem obložení stropu ve střední části střechy, kde může být taková clona v kolizi s tímto obložením. V takovém případě se musí použít samostatná clona, viz první varianta.Until now, either a mechanical screen or a screen made of ceramic print on the glass has been used to prevent glare from the sun in the area above the rear-view mirror. The mechanical orifice plate has two different designs. The first variant is a separate plastic part, which is located in the ceiling trim and, if necessary, folds out and covers the area above the interior rear-view mirror. The second variant is a solution where the blind to cover the space above the rear-view mirror is part of the two main sun blinds against glare. This solution is limited by the shape of the ceiling lining in the central part of the roof, where such a curtain may conflict with the lining. In this case a separate orifice must be used, see first variant.

Jiné řešení představuje clona, která je vyrobena stejnou technologií jako černý keramický potisk na skle. Tato clona je umístěna na vnitřní straně skla v oblasti výhledu nad zrcátkem a je tvořená poměrně hrubým rastrem, tvořeným tečkami o velikosti řádově v milimetrech.Another solution is an orifice manufactured using the same technology as black ceramic printing on glass. This aperture is located on the inside of the glass in the area of vision above the mirror, and is formed by a relatively coarse screen consisting of dots of the order of millimeters.

Nevýhoda mechanické clony spočívá v tom, že je neprůhledná, takže při jejím použití není v oblasti, kterou zakryje, žádný výhled nad vnitřním zrcátkem. Průhled clonou, tvořenou rastrem, je také nekvalitní, neboť je tvořen ze 100 % neprůhledných a průhledných oblastí.The disadvantage of the mechanical iris is that it is opaque, so that when it is used, there is no view over the interior mirror in the area it covers. The screen through the screen is also of poor quality, as it consists of 100% opaque and transparent areas.

Podstata vynálezuSUMMARY OF THE INVENTION

Výše uvedené nedostatky do jisté míry odstraňuje třetí sluneční clona, tvořená barevnou clonící vrstvou na polyvinylbutyralové (PVB) fólii, která je umístěná mezi první a druhou skleněnou vrstvou čelního skla automobilu a umožňující průhled oblasti nad vnitřním zpětným zrcátkem, přičemž barevná clonící vrstva je transparentní s barevným odstínem, jejíž světelná propustnost je po celé ploše sluneční clony stejná nebo dle potřeby proměnná a není větší než 25 %.To some extent, the above-mentioned deficiencies are overcome by a third sun visor, consisting of a colored visor layer on a polyvinyl butyral (PVB) film, which is positioned between the first and second car windshields and allows viewing the area above the interior rearview mirror. a color shade the light transmittance of which is the same throughout the sun visor area or varies as necessary and is not more than 25%.

Třetí sluneční clona 1 má směrem do stran od bočních hran 8, 8' a směrem od spodní hrany 9 dolů k spodnímu okraji čelního skla 10 rozprostírající se boční přechodová pásma 6, 6' a spodní přechodové pásmo 5 třetí sluneční clony 1, přičemž v tomto spodním přechodovém pásmu 5, směrujícím od spodní hrany 9 třetí sluneční clony 1 směrem dolů, které je stejně široké jako přechodové pásmo 16 stínícího pruhu 3 čelního skla 10 automobilu, dochází k pozvolnému nárůstu světelné prostupnosti z hodnoty světelné prostupnosti třetí sluneční clony 1, která je menší nebo rovna 25 %, na hodnotu světelné prostupnosti čelního skla 10 automobilu (minimálně 75 %) a v bočních přechodových pásmech 6, 6' dochází k pozvolnému přechodu světelné prostupnosti z hodnoty světelné prostupnosti třetí sluneční clony £, která je menší nebo rovna 25 % na hodnotu světelné prostupnosti stínícího pruhu 3 čelního skla 10 automobilu.The third sun visor 1, located in the upper part in the middle of the windshield 10 of the car in the shielding strip 3 of the windshield 10, is delimited according to FIG. 1 by an upper edge 7 bounded by a lower edge. , 8 ', by projecting the lowered main mechanical curtains of the driver and passenger on the windshield 10 of the automobile, and the lower edge 9, delimited by the transition line 15 of the shielding strip 3 of the windshield 10 of the automobile. The third sun visor 1 has lateral transition zones 6, 6 'and a lower transition zone 5 of the third sun visor 1 extending laterally from the side edges 8, 8' and downwardly from the lower edge 9 to the lower edge of the windshield 10. a lower transition zone 5, directed downwardly from the lower edge 9 of the third sun visor 1, which is as wide as the transition zone 16 of the car windshield 10, there is a gradual increase in light transmittance from the light transmittance value of the third sun visor 1 less than or equal to 25%, to the light transmittance value of the windshield 10 of the car (at least 75%), and in the side transition zones 6, 6 ', the light transmittance is gradually transitioned from the light transmittance value of less than or equal to 25% to the light transmittance value of the windscreen shielding strip 3 10 automobilu.

Třetí sluneční clona £ podle obr. 2 je vytvořena barevnou clonící vrstvou 12, nanesenou na PVB fólii 11, která je umístěná mezi první skleněnou vrstvou 13 čelního skla 10 a druhou skleněnou vrstvou 14 čelního skla 10. PVB fólie 1 1 je polyvinylbutyralová fólie, která se standardně používá v laminovaných sklech, je zalaminována mezi první skleněnou vrstvou 13 a druhou skleněnou vrstvou 14 čelního skla 10. Barevná clonící vrstva 12 je stejná jako standardní inkoustová barva, používaná pro stínící pruh 3 čelního skla 10 automobilu. Barevný odstín třetí sluneční clony £ může být šedý, zelený nebo modrý.The third sun visor 6 of FIG. 2 is formed by a colored screen 12 applied to the PVB film 11, which is disposed between the first windshield 13 and the second windshield 14. The PVB 11 is a polyvinyl butyral film that is standardly used in laminated glass, is laminated between the first glass layer 13 and the second windshield 14 of the windshield 10. The color screen 12 is the same as the standard ink used for the windshield 3 of the windshield 10 of the automobile. The shade of the third sunshade can be gray, green or blue.

Třetí sluneční clona £ podle obr. 3 je vytvořena barevnou clonící vrstvou 12, nanesenou mezi PVB fólie 11, ££', které jsou umístěné mezi první skleněnou vrstvou 13 čelního skla£0 a druhou skleněnou vrstvou 14 čelního skla 10.The third sun visor 10 of FIG. 3 is formed by a colored screen 12 applied between the PVB films 11, 10, which are disposed between the first windshield 13 of the windshield 10 and the second windshield 14 of the windshield 10.
