Abstract
A shield lock assembly for releasably securing a rotatable helmet shield includes a post having a threaded post and a post body, a detent button slidably mounted relative to the post body, and a compression spring positioned within a spring chamber defined cooperatively by the post body and the detent button. The detent button includes an internal annular flange that engages a lip on the post body to limit axial movement and retain the detent button on the post. The spring biases the detent button toward an extended locking position for engagement with a shield aperture. The threaded post may be offset from a central axis of the detent button.
