ABSTRACT:
The visor arrangement of the present invention includes a visor element and support apparatus to support the element in a pivotable state between a lowered, operative position and a raised, inoperative position on a protective helmet or other holder which can be applied on the user's head. The support apparatus is a pair of support arms, each consisting of two detachably connectable parts pivotable in relation to each other. One of the parts is provided with a laterally protruding journalling-pin element, while the other is provided with a laterally running through-opening into which the journalling pin can be inserted. The pin, due to the action of flange members arranged at its free ends and protruding laterally, is detachably retained in a state with limited pivotability about a first pivot point defined by a first longitudinal part hereof, to be turned about this point between two predetermined, stable positions corresponding to the two stated positions of the visor element, during displacement of an opposite second longitudinal part of the journalling-pin element along an abutting flexible wall portion of the opening. This second longitudinal part of the journalling-pin element defines a second pivot point for the journalling-pin element about which this can be turned from one of the two predetermined positions to a free position in which it can be removed from the opening.
