Abstract
Abstract Head mounting apparatus which can accommodate different head sizes and shapes comprises a substantially rigid member for supporting equipment, such as night vision equipment, to be used by the wearer, and a flexible member which can flex to adapt to the head of the wearer. The rigid and flexible members are connected by pivotal means at pivot positions along spaced pivotal axes. The flexible member has buttons for attachment of straps by which it is in use secured to the wearer's head. The position of the rigid member relative to the flexible member may be adjustable by manual rotation of knobs.
