US Patent 11992077 Two layer chin cup

A chin cup has a hard outer cup and a soft inner cup that may be removable from the outer cup. The inner cup has a peripheral edge extending beyond the edges of the outer cup. Strap guides that allow a strap to slide through. A one size fits all design includes a central indentation that extends upward toward a top central portion of the cups as well as a central narrowing longitudinally of the cups. Aligned vent holes between the cups let the user's chin breathe. The cups have an arcuate longitudinal arch shape. The chin cup includes a boss and hole design that has mushroom caps that prevents the separation of the cups when not in use, the soft inner cup imbedded in the hard outer cup.
