Abstract: An assembly is provided for use in securing a secondary unit, such as a welder's mask or the like, to a primary unit, such as a protective helmet often referred to as a hard hat. The secondary unit is mounted for adjustment between operative and inoperative modes relative to the primary unit. The primary unit is provided with at least one exterior shoulder projecting laterally outwardly from a wall surface. The shoulder is provided with an upwardly extending passageway. The assembly includes a base portion which rests upon and is supported by the shoulder. Connected to and depending from the base portion are a plurality of fingers which extend into and resiliently engage the shoulder passageway and retain the bracket in assembled relation with the primary unit. Adjustable means coact with the base portion to secure the secondary unit to the bracket base portion whereby the secondary unit can assume a selected mode relative to the primary unit.
