ABSTRACT:
A latch mechanism for controlling relative movement of two hinged members about an axis, e.g. a helmet and visor. The mechanism comprises a first part (19) fixed to one hinged member and a second part comprising a first member (25) fixed to the other hinged member (13) and a manually operable second member (27). On application of pressure the second member (27) pivots on the first member (25) against a spring bias (43) to disengage the second member from the first part (19) and allow the second latch part (25, 27) to move angularly with respect to the first latch part (19) under continuing pressure on the second member.
