Chin strap

A chin strap comprising:

• a protective shell including an outer surface that faces away from a user's chin during use of the chin strap, the outer surface including a curved and convex contour extending between lengthwise ends of the shell, the shell further including a first curved edge extending between the lengthwise ends along a top edge portion of the shell and a second curved edge extending between the lengthwise ends along a bottom edge portion of the shell that extends below the user's chin during use of the chin strap, wherein the first curved edge includes a concave contour, the second curved edge includes a convex contour, the convex contour of the second curved edge is centrally located along the second curved edge, and the second curved edge further includes a first concave contour located between a first lengthwise end of the shell and the centrally located convex contour of the second curved edge and a second concave contour located between a second lengthwise end of the shell and the centrally located convex contour of the second curved edge;
• and
• a cushion member secured to an inner surface of the shell that opposes the shell outer surface, wherein the cushion member includes a surface including a curved and concave contour that extends between lengthwise ends of the cushion member such that the cushion member engages with the user's chin during use of the chin strap;
• wherein a cross-section along a lengthwise central axis of the chin strap defines first and second outer surface shell portions that are asymmetrical such that the first outer surface shell portion of the cross-section including the first curved edge defines a first area that is less than a second area defined by the second outer surface shell portion of the cross-section including the second curved edge.
