Abstract
A chin strap buckle for securing a protective helmet to a wearer's head includes a female snap fastener member and a male snap fastener member which snappingly interlock together at their respective one ends in a pivotal relationship. The female member is formed of a substantially triangularly-shaped mid-portion and left and right end portions formed integrally with the opposite sides of the mid-portion. The mid-portion has a trough-like recess formed at its top. The male snap fastener member is formed of a triangular body portion and a lower end portion. The body portion has a post extending outwardly therefrom adjacent its top. The post has an enlarged button and a neck connecting the button to the body portion. The neck of the body portion of the male member is snappingly received within the trough-like recess formed at the top of the female member for interlocking the male and female members together. Stop members are formed upon the female member for limiting the rotational or punctual movement of the male member relative to the female member.
