Abstract
An anti-dazzle eye shade for protection against natural or artificial light rays in a reliable and effective safety system for protection of drivers against dazzling. An opaque or slightly transparent support is adapted to be held to the wearer's head at the level of the eyes. The support has an upper horizontal part, a front vertical part and two side blinders. The front part has sloped cutouts at the level of the eyes and is provided with laterally slidable portions each having a notch flared toward the bottom. The notched portions may be adjusted to the visual field of the wearer. In this way maximum protection of the eyes is obtained against all radiation outside of the direct field of vision of the wearer.
Claims8
An anti-dazzle visor to selectively limit the wearer's unobstructed field of view for protection against natural or artificial light rays from outside said limited field of view, comprising a support and adaptation means for adapting said support to the wearer, said support comprising:
- a horizontal part with a curved side for adjustment to the wearer's head;
- an essentially vertical front part connected at the top thereof to said horizontal part at the side thereof opposite said curved side, said front part being provided at the level of the wearer's eyes with sloping cutouts, said cutouts being held at a distance in front of the eyes determined by the width of said horizontal part;
- two parts connected to said horizontal part and said front part at the sides to form blinders at the level of the temples of the wearer;
- two notched parts each having a notch widened at the bottom and each being connected to each of a respective one of said sloping cutouts and being rectilinearly slidable in a lateral direction for rectilinar lateral slidability of the notches within said cutouts without producing a gap either at the top or sides of the notched parts, each of said notched parts defining an unobstructed field of view determined by the lateral position of the notch, for a fixed head position, and the distance of the notch from the eye, the greater the distance, the more limited the field of view;
- pushbutton means connected to each of said notched parts for allowing easy lateral shifting adjustment thereof within said sloping cutouts;
- and
- marking means on each of said notched parts and on said front part for indicating the relative lateral position of each of said notched parts,
- wherein said support is pivotally connected to said adaptation means such that the support, and particularly said front part, may be tilted upwardly and downwardly, and
- wherein a portion of one side of each of said notched parts adjacent to and on the same side of each notch is made of tinted transparent material to absorb or reduce the intensity of light rays reaching the eye from certain angles outside the desired field of view.
