ABSTRACT:
A pivot assembly for use with headgear that includes a headtop and a shield, and a method for coupling the headtop to the shield using the pivot assembly. The pivot assembly can include a housing, a socket dimensioned to be received in the housing and having a plurality of first engagement features, and a post having a plurality of second engagement features adapted to engage the first engagement features. The pivot assembly can further include a spring dimensioned to be received in the housing to bias the first engagement features and the second engagement features into engagement, while allowing relative rotation between the post and the socket. A method can include moving the socket in a first direction into the housing, moving the post in a second direction that is different from the first direction toward engagement with the socket, and moving the spring in the first direction into the housing.
