The helmet visor can pivot for adjustment into at least three distinct positions. At its two upper rear ends is a narrow, light bearing mechanism which is detached with the visor when it is dismantled from the helmet. - The bearing mechanism is fitted at one end of an arm pivotable w.r.t. the visor, and whose other end has components for simple fixture to the helmet. The mechanism comprises a spring loaded lock pin which works in conjunction with sunken parts to provide different adjustment positions for the visor. |
