An earmuff assembly comprising two earmuffs (10) each provided with a respective sealing ring (12). A fork-shaped member (14) is pivotally connected on the one hand - at the end of each fork leg - to a corresponding earmuff (10) and on the other hand - centrally - to a resilient headstrap unit (16) at its other end. When the earmuff assembly is not in use, the earmuffs (10) can be collapsed towards one another beneath the headstrap (22) of the headstrap unit (16), for self-locking through the medium of the spring force in the headstrap (22). The connection between a fork-shaped member (14) and the headstrap unit (16) is effected through the medium of pivot hooks (28) provided on respective ends of the headstrap unit (16) or on the central part of the fork-shaped member (14) and intended for gripping coaction with one or more corresponding pivot pins (26) on the central part of the fork-shaped member (14) or on respective ends of the headstrap unit (16). The pivot hooks (28) can only be engaged with and released from the pivot pins (26) when the fork-shaped member (14) and the headstrap unit (16) are in a mutually predetermined position in which the earmuffs (10) are unattached in relation to the fork-shaped members (14). This position is latched by the earmuffs (14) subsequent to mounting the same. |
