DE2603984A1 - Antidazzle screen for windscreen - comprises tinted plastics film stretched over inside of windscreen - Google Patents

Abstract

A tinted plastics film is reeled up at the top edge of the windscreen and is pulled down to cover all, or part of, the windscreen to eliminate dazzle. The density of tinting is greatest at the bottom edge of the film to reduce reflected light from wet roads, and can be partially pulled down to sit in front of the driver's eyes for low sunlight. The edges of the film are braced by wire inserts and the film is secured by suction pads or any other fittings. The film can serve as an emergency windscreen if the screen is broken and can also be formed by an inflatable plastic body which is self erecting. The tinting can be replaced by liq. crystal areas in front of the driver.

Description

Patent application with utility model auxiliary application Continuously adjustable glare protection for motor vehicles

The invention relates to a continuously adjustable glare protection for vehicles, in particular motor vehicles.

A glare protection must be used at every position in the sun and also on wet streets that shine the headlights of the oncoming ones Car reflects, be effective without impairing the view.

The sun visors that are common today in motor vehicles only partially fulfill their purpose because they cover, when folded down, only the uppermost part of the windshield and cannot be adjusted to the size of the driver. Even if they are one-sided are unhooked and placed at an angle from top to bottom, the driver must look past it on the left or right to the road to be able to overlook. In addition, the inclined position is irritating Cover; it is not transparent. A glare protection that makes it necessary to wear sunglasses fails to do its job.

According to the invention, the glare protection consists of a tinted, transparent plastic film, which when not in use over the windshield is rolled up or guided in the roof (headliner) of the vehicle, pulled out there down to the dashboard and can be moored there. It can have a sufficient width for the field of view, but also over that the whole width of the windshield is enough and that too

Cover the passenger’s field of vision. Is according to the invention the anti-glare film was heavily tinted at the bottom and steadily less strongly tinted at the top, so that it reflected from the rain-soaked streets Spotlight is dimmed down strongly. The heavily tinted lower part can also be adjusted if required brought at eye level and therefore the glare protection can also be adapted to the size of the driver. Through appropriate Edge reinforcement of the foil and inlay of spring steel wire, the foil adapts to the curvature of the windshield. Besides that the glare protection offers additional protection in the event of a breakage of the windshield and a wind protection in the event of a total failure, as it can be attached to the dashboard. In order to avoid reflections on the side facing the driver, this is anti-reflective coating by methods known per se.

For a further embodiment of the invention, the glare protection consists of an air-filled, flat bag-like, preferably rectangular structure made of plastic film. The shade used is preferably that of sunglasses. To determine at any height are attached below, on both sides or in the middle, e.g. suction cups or other means, such as glue points, holding the visor to the windshield. In the case of cars with a sliding roof, there is generally enough space to accommodate the glare protection in the roof. In this case, the anti-glare film is on the upper edge of the windshield Can be rolled up with appropriate spring balances. To further refine the invention, in one part, preferably in the field of view of the visor, in a known manner by means of

Liquid crystals, a self-adjustment to the brightness.

There is no need for a description based on drawings, as pictorial representations do not provide any further, better insight and the corresponding devices of a motor vehicle are generally known and familiar.
