ABSTRACT:
A locking and release mechanism for a helmet which, on release, permits rotation of the visor in either direction. The mechanism comprises an arcuate track (23) fixed to the helmet shell (11). The visor is preferably mounted on an arm (19) rotatable about an axis transverse of the shell and connected to a subsidiary arm (27) rotatable about the same axis. On the arm is a shoe (31) with a flat surface (37) opposing arcuate surface (25) of the track. Two interengaging operating members (45, 47) with respective guide surfaces are pivotally mounted on the shoe. Two outwardly biassed rollers (95, 97) are located between the opposed surfaces. Movement of the operating members against the rollers' biassing brings the guide surfaces into contact with the rollers and pushes them from wedging engagement to release the mechanism permitting rotation of the visor against low opposition from the rollers.
