Abstract
Abstract An earcup suspension for a full coverage protective helmet makes use of a ball and socket between a rigid head contacting earcup and an adjustable assembly attached to the helmet shell. The adjustable assembly is manipulated by a knob on the exterior of the helmet shell which has a threaded engagement with a stud to which the ball is connected. Because the stud is secured to prevent rotation, it is moved inwardly or outwardly by rotation of the knob so as to adjust the snugness of the fit of the rigid earcup with respect to the wearer''s head.
