Abstract: An article of headgear, such as a safety helmet, comprises a shell (10) with an outer surface having at least one locating notch (14, 16) defining an opening (22). The notch has first and second ends (24, 26), a base, and side walls (30, 32) extending from the base to the outer surface to form a continuous surface with the outer surface of the shell. The width of the opening decreases from one end towards the other. The depth of the side walls increases from one end towards the other. The width of the base decreases from one end towards the other and is wider at the other end than the width of the opening at the other end. The shell has a slot (20) in the outer surface aligned with the end of the notch. A mounting clip (40) comprises a mounting plate (42) and a locating tongue (48). One end is connected to the end to the mounting plate so that the tongue extends parallel to the mounting plate.

Abstract: A visor carrier assembly for a safety helmet includes a double-pivot mechanism attachable to each side of a safety helmet and configured to enable a visor to be selectively pivoted. An elongate arm of the double-pivot mechanism includes first and second pivotal couplings, each including a coupling member being a fixed elongate pin having rounded portions at each end, and a coupling region including an aperture defining, along its inner edge, a first notch or aperture within which one of the rounded portions of a respective coupling member is received to define a fixed pivot point, and an arcuate guide wall with which the opposite rounded portion of said respective coupling member engages and having ridges defining grooves or notches for receiving the opposite rounded portion as a respective pivotal coupling is pivoted about the fixed pivot point, each groove or notch defining a respective said visor position.

Abstract: A visor carrier assembly for a safety helmet, comprising: a visor; and an attachment device for attaching the visor to a safety helmet for use, the attachment device including a double-pivot mechanism attachable to each side of a safety helmet and configured to enable the visor to be selectively pivoted relative to said safety helmet, in use, between at least first, second and third visor positions, each double-pivot mechanism comprising an elongate arm, said elongate arm being coupled, by a first pivotal coupling at one end thereof, to a respective side region of the visor and coupled, by a second pivotal coupling at a longitudinally opposing second end thereof, to a fixed point, in use, at a respective side of said safety helmet, each pivotal coupling comprising a coupling member and a coupling region, each coupling member comprising a fixed elongate pin having rounded portions at each end, each coupling region comprising an aperture defining, along its inner edge, a first notch or aperture within which one
