Abstract
The device (FIG. 1) is provided in combination with helmet A and related vizor B, with a box shaped gear and pinion assembly 10, secured by pin 12 to helmet A. A gear wheel 14, secured to side wall A of the helmet, engages, via pinion 20 held by gear and pinion assembly 10, with a sector gear (rack) 24 also secured to said gear and pinion assembly which is torsionally connected to the end of vizor B. When assembly 10 is caused to oscillate in the clockwise direction to lift vizor B, a complementary counter-clockwise oscillation is imparted to same to permit complete lifting of the vizor, so that its top edge may approach and fit tightly over the surface of helmet A.
