FIELD: transport engineering; ground, water and air vehicles. SUBSTANCE: invention can be used in automobiles, locomotives, sea vessels for cleaning sight windows from dust and other precipitations in service. According to invention additional elastic blade with shock absorbing frame and carrier are placed between upper end of main carrier and blade and guide belt. Additional carrier is hinge-coupled by one end with upper end of main carrier, and by other end, is hinge-coupled with slot of guide belt. Additional carrier is provided with ball from side of end pointed to belt, and profile of slot of belt is made cylindrical, forming lock joint at connecting. Carriers are rigidly connected with shock absorbing frame of blades, respectively, more over, space of belt is open from its both end faces, lengths of main blade and carrier are equal and commensurable with half of length being not greater than lower base of glass. Summary length of main and additional carriers is commensurable with distance from of support to inner surface of belt slot space in apex of changing of its side part into upper part. Invention improves observation of road and oncoming and side running vehicles. EFFECT: improved reliability of cleaning of window glasses at any season of year and safety. 6 dwg |
