CONTROLLED LIFTING DEVICE, FOR HELMET VISORS AND THE LIKE, AND HELMETS EQUIPPED WITH SUCH A DEVICE

摘要

A LIFTING DEVICE INCLUDING A GEAR SYSTEM 10, FIXED BY A SHAFT 12 TO A HELMET WITH A TOOTHED WHEEL 14, FIXED TO THE SIDE WALL OF THE HELMET A, IS IN CONNECTION, VIA A PINION 20, WITH A TOOTHED AREA 24 WHICH IS ATTACHED TO THE END OF A VISOR B. WHEN THE SYSTEM 10 IS PIVOTED IN THE CLOCKWISE DIRECTION TO LIFT VISOR B, THIS IS SUBJECT TO ADDITIONAL PIVOTING ON THE OTHER SIDE, WHICH ALLOWS THE FULL LIFTING OF VISOR B, SO THAT ITS UPPER EDGE MAY GET CLOSE TO THE SURFACE OF HELMET A AND TIGHTLY ADAPT TO IT.
