COMBINATION FILTER-VISOR Russian patent published in 2001 - IPC

FIELD: transport engineering; safety on roads. SUBSTANCE: invention relates to devices preventing blinding of on-coming drivers. Device is based for its operation of polarized irradiation for providing safety. It has visor installed for turning relative to axle of attachment bracket on vehicle and filter with holder installed on antiblinding visor which is essentially a body. Filter is made polarizing and is installed on holder for movement and drawing out of body. Body is furnished with interlock to prevent turning relative to bracket axle. Antiblinding visor is made on base of polarization filter whose polarization plane is orthogonal to polarization plane of polarization filter and is similar to polarization plane of polarization filter developed close visor relative to holder axle through 180 deg. Both filters are secured by this axle. EFFECT: provision of filter-visor playing part sun visor and antiblinding polarization filter. 8 cl, 14 dwg
